Description
The present invention relates to the flywheel of improved electromechanical fastener driving tool, relate in particular to a kind of like this flywheel that on its circumference working face, has one or more grooves, groove extends to another side along the working face circumference and from one side of working face, has avoided making loss of friction or forfeiture between the contact-making surface because of piling up impurity on driver-flywheel contact-making surface.
Motor-driven ailing machine and stapler (staple drives nailing machine) are well-known technically, and extensively are applied.This is because they are than manually can drive securing member sooner more accurately.Usually see most that the form of usefulness is, this motor-driven ailing machine and stapler drive by compressed air, and the flexible pipe that therefore needs air compressor and length accompanies with it.
In recent years, interest has taken place to dynamo-electric ailing machine and stapler in people, because as long as at the scene of using power supply is arranged, and building-site always has electric energy to use.This instrument also is suitable for family's use that electric energy very easily obtains.
People have invented the electromechanical fastener driving tool of many types, disclosed a kind of electric stamping tool as United States Patent (USP) 4042036,4204622 and 4323127, in this instrument, driver is to utilize two counterrotating flywheels to finish its impulse stroke by the engagement of frictional force, and each flywheel has its motor.United States Patent (USP) 4121745 has also disclosed a kind of counterrotating flywheel that utilizes, finish the electric stamping tool of its impulse stroke by frictional force engagement driving driver, yet in this patent, a flywheel is directly by a Motor Drive, and another flywheel drives by belt pulley and rubber strip, geared system or analog with same motor.
United States Patent (USP) 4189080 and 4298072 has disclosed a kind of electromechanical fastener driving tool, and wherein driver is to utilize the flywheel of single high speed rotation to drive and finish its impulse stroke.This driver is engaged between a single flywheel and the support member.The most frequently used structure of support member comprises the roller of a low inertia.Other bracing or strutting arrangements as linear bearing or polytetrafluoroethylene (PTFE) pulley, as pointing out in these patents, also can be used for finishing same purpose.
Above-mentioned Electrical Mechanician prodigiosin is used for driving nail, staple or other securing member.The present invention is described with its example that is applied as in dynamo-electric ailing machine, and still, technical staff in the art can understand, and the present invention is equally applicable to dynamo-electric staple driven tool.
All electromechanical fastener-driving tools all exist a common problem.This problem is exactly can pile up impurity on the driver and this impurity can be transferred on a flywheel or a plurality of flywheel from driver, and finally the loss because of the frictional force of driver and one or more flywheel has destroyed good driving function.
For example, common way is to have arranged nail with parallel spaced-apart relation in the tool box, and keeps this parallel relation by the tape that use scribbles the thermoplasticity PUR.Another common way is, is coated in the initial drive part of each nail body at least with coating such as resins, so that help nail to penetrate workpiece, in case and after nail is driven into, increase the confining force of nail.
Because driver is to utilize with the friction engagement of at least one flywheel to finish its impulse stroke, so when tool using, driver can generate heat.In fact the heat that obtains of driver be enough to melt PUR on the nail or coat or its both.When driver under the extruding force effect between flywheel (or between flywheel and bracing or strutting arrangement) when motion, the material that has melted is piled up in the front of driver-flywheel contact area, arrives the stage that loses frictional force and driving force up to occurring sliding or float and contact between driver-flywheel being descended.
Such driver provided by the invention generally comprise forward direction with parallel, plane, relative broad and back to and the paddle-like element of the working surface that has long and narrow edge.This driver also can be provided with at one or two buttock and import the conical surface or inclined-plane.Working face is meshed by counterrotating flywheel or a flywheel and a bracing or strutting arrangement.When the working face of paddle-like driver during, be added to the downward power (F of driver by two flywheels or a flywheel and a support component engagement
D) can be explained by following formula:
F
D＝XN（μCos
2θ-SinθCosθ）
N is the extruding force that is added on the drive operation face here, and μ is a coefficient of friction, and X is flywheel number (1 or 2), and θ is the cone angle of the importing conical surface on the driver or the oblique angle on inclined-plane.As can be seen from the above equation, for normal pressure (vertical force) N, when the μ value descends, in order to keep onesize downward force (F
D), the N value must increase.Be appreciated that in addition added extruding force can only be out of shape and other problem otherwise will produce driver in rational (appropriateness) scope.As a result, be lower than acceptable limit when following, must take instrument cleaning driver and flywheel or flywheel and bracing or strutting arrangement usually apart, thereby cause instrument to quit work when frictional force is reduced to driving force.The accumulation of impurity also can make the wearing and tearing of the working face of the working face of the working face of driver and flywheel or flywheel and support member increase.
United States Patent (USP) 4519535 touches this problem specially, is quoted for your guidance here for this reason.This patent points out that (maybe when using two flywheels, two flywheels all are provided with annular (circumference) groove, and then the meeting that produces makes the impurity accumulation of frictional force decline can reduce to minimum if flywheel is provided with annular (circumference) groove between one or more flywheels and driver.These grooves parallel with two parallel edges of flywheel working face.These grooves are provided with to such an extent that make total contact area that can keep best between one or more flywheels and driver.These grooves trend towards flowing into therebetween along driver-flywheel contact wire formation cavity, impurity.As a result, a multiple week in a week is in considerable time, by the positive friction engagement of one or more flywheels generations to driver.And, the working life of the working life of one or more flywheels, especially driver, because the minimizing of the wearing and tearing of these elements, and greatly increase.
The present invention has made improvement to above-mentioned United States Patent (USP) 4519535.Though can obtain good result according to this patent, if at (or two flywheel working face on) formed one or more grooves on the flywheel circumference working face, not only also pass across the circumferential surface an of flywheel (or two flywheels) in a circumferential direction but also simultaneously, will obtain better result.In other words, the parallel edge of the flywheel working face at groove of the present invention and groove place can clear be seen this point at angle below.
Scroll of the present invention or be that spiral groove has played extruding and swept effect basically, this interaction energy makes the working face of driver and the working face of one or two flywheel keep the cleaning of longer time.
Behind a large amount of cycle periods, can see the working face of driver that can the wearing and tearing adjacency with edge parallel annular (circumference) groove (described in United States Patent (USP) 4519535) of flywheel circumference working face, on the driver of the position of enegine pit, produce ridge edge longitudinally.These ridge edge have been represented the area of the working face that does not wear and tear so muchly at least on the driver as all the other working faces.Therefore these ridge edge have been represented that part of area that total life-span of drive operation face is not made contributions.In fact they are inoperative areas.What otherwise groove of the present invention produced for the drive operation face of adjacency is uniform wearing and tearing, thereby makes the working life of driver longer.
According to the present invention, provide a kind of improved flywheel that is used for electromechanical tool such as ailing machine or stapler.This instrument is a kind of instrument with a driver, and this driver is to utilize electricity to drive flywheel by finishing its impulse stroke with the flywheel friction engagement.This driver is squeezed between flywheel and support member (i.e. counterrotating flywheel, a low inertia roller, a polytetrafluoroethylene (PTFE) pulley or an analog).According to the present invention, flywheel is provided with one or more groove on its circumference working face, keeps best contact simultaneously between flywheel and driver.These grooves on the flywheel become angle relation with two parallel edges of the flywheel working face at their places, they extend along annular (circumference) direction with respect to the horizontal direction of flywheel circumference working face on the circumference working face of flywheel.When two flywheels were arranged in the instrument, these two flywheels all were provided with groove of the present invention, and its traffic direction is opposite.
Groove of the present invention not only constitutes the impurity inflow cavity wherein that makes on driver and the flywheel along contact wire or many contacts wire of driver-flywheel, and also has extruding and cleaning effect, so that clean the working face of these elements more up hill and dale.And the working face of these elements, especially driver, wear and tear to such an extent that compare uniformity, therefore make the working life of driver longer.
Fig. 1 is the local sketch map of support member of driver, flywheel and the low inertia roller type of prior art.
Fig. 2 is the local sketch map of expression one driver and a pair of relative rotary flyweights.
Fig. 3 is the front view according to flywheel of the present invention.
Fig. 4-the 11st, the sketch map of the flywheel circumference working face on generate plane shows the various structures by the formed groove of the present invention.
Apparent of the present inventionly be applicable to that any wherein driver is by finishing the electromechanical fastener driving tool of its impulse stroke by friction engagement with at least one high speed rotary flyweights.
The Fig. 1 that leaies through earlier the figure illustrates the flywheel of a driver, a rotatable driving and the bracing or strutting arrangement of a low inertia roller type.The general structure of this pointed class electromechanical fastener-driving tools in Here it is the United States Patent (USP) 4189080 recited above and 4298072.
Driver 1 comprises elongated paddle-like element, and this element has forward direction working face 2, back to working face 3 and long and narrow vertical limit, and one of them limit is represented with 4.
As example, described low inertia roller 6 just moves to the activation point shown in the dotted line 6a with the direction of arrow B.This moving of roller 6 can be finished in any suitable manner, realizes (not shown) as the bindiny mechanism that links to each other with the contact workpiece safety device by use, and this knows in prior art.
Note that as shown in Figure 1, it can not drive its work by flywheel 5 and low inertia roller 6 when driver 1 is in contraction normality position, moved to its work (driving) position 6a even work as roller 6, also is like this.This is because driver 1 is provided with groove mouth 7 nominal thickness of driver 1 is reduced.Groove mouth 7 partly links to each other with the driver normal thickness by importing the conical surface or inclined-plane 8.
As shown in Figure 1 usually in the operation of the prior art driven tool of type, flywheel 5 is at first driven by its drive motor (not shown) energising and with the direction rotation of arrow A, energising is to be finished by the electric switch that the hand switch (not shown) drives.When the head (not shown) of instrument is positioned on the workpiece that nail will be driven into, workpiece touch-safe device can move on to low inertia roller 6 position of its 6a, make switch (not shown) closure simultaneously, make solenoid (not shown) energising and driver 1 moved down the engagement mouth that enters flywheel 5 and roller 6.
When roller 6 was in its position 6a, the distance between roller 6 and the flywheel 5 was lower than the nominal thickness of driver 1, as mentioned above.For inclined-plane 8 and driver 1 that upper part (working face part) can be between roller 6 and flywheel 5 by and by roller 6 and flywheel 5 engagements, roller 6 and flywheel 5 both one of install to such an extent that can back off so that driver 1 can be entered therebetween and driven by them.
In case nail or securing member are driven in by driver 1, instrument can make roller 6 get back to its normality position from the safety device of workpiece rise and response workpiece.So driver 1 disengages with flywheel 5 and roller 6.Driver 1 after certain device makes and disengages is got back to the normality position of contraction as shown in Figure 1.
The schematic diagram that Fig. 2 is the simplification described in above-mentioned United States Patent (USP) 4042036,4204622,4323127 and 4121745 has represented to utilize the driven tool of the typical prior art of two relative rotary flyweights among the figure.Among the figure, the paddle-like driver is designated as 9, and it has working face 10 and 11, and driver 9 is between a pair of flywheel 12 and 13.Such as explained above, flywheel 12 and 13 each by they Motor Drive separately, can be with the rotation of the direction of arrow C and D, perhaps flywheel 12 and one of 13 is directly driven and another available same motor drives indirectly by a motor.
As shown in Figure 2, flywheel 12 and 13 is being separated by the distance greater than the nominal thickness of driver 9 when being in not the normality that drives each other.Fig. 2 shows that also driver 9 is in the normality position that does not drive.One or two can move so that draw close mutually in the flywheel.As example, flywheel 13 just moves to the activation point 13a shown in the dotted line among the figure with the arrow E direction.When flywheel 13 was in its activation point 13a, the distance between it and the flywheel 12 was less than the nominal thickness of driver 9, yet driver 9 forms a pair of opposite groove mouth 14 and 15 in its working face 10 and 11. Groove mouth 14 and 15 joins with separately working face 10 and 11 respectively by the opposite importing conical surface or inclined- plane 16 and 17.
The work of Fig. 2 embodiment is quite similar with the relevant description of Fig. 1.At first, utilize, allow one or two motor of flywheel 12 and 13 switch on, make the direction rotation of flywheel with arrow C and D by the suitable switch (not shown) of manual activation.Make flywheel 13 move on to its activation point 13a then.This available any suitable mode is finished, and comprises the suitable bindiny mechanism that utilization links to each other with the contact workpiece safety device.After this, by suitable mechanical device, for example solenoid or analog move down driver 9 between flywheel 12 and 13.Flywheel 12 and one of 13 also is to install to such an extent that move after can be slightly, and the chamfered portion 16-17 of driver 9 and working face part 10-11 can be entered therebetween.In case flywheel 12 and 13 engages the working face 10 and 11 of driver 9, they just make driver 9 finish its fastener drive stroke.When the fastener drive stroke finished, instrument rose from workpiece.D/d contact workpiece safety device makes flywheel 13 move on to its normality retracted position according to the opposite direction of arrow E, and at this moment, the distance that it and flywheel are 12 is greater than the nominal thickness of driver 9.As a result, as shown in Figure 2,, driver 9 is disengaged, get back to its normality, non-activation point by the appropriate device of prior art.
Can see from Fig. 1 and Fig. 2, driver 1 and 9 by with they separately flywheel 5,12 and 13 friction engagement be driven.As a result, driver 1 and 9 can heating.In fact, driver can be warm to the PUR that is enough to melt on the band that keeps the nail appropriate location in the tool box.The nail that so connects together so-called " nail that clings ".Driver 1 and 9 heating also are enough to melt any coating that is coated on driven nail.These materials that melted can be bonded on the driver, transfer to then on the flywheel or two flywheels of adjacency.Also can further see from Fig. 1 and Fig. 2, when driver 1 and driver 9 between roller 6 and flywheel 5 and between flywheel 12 and 13, when moving under the extruding force effect, the impurity in the flywheel on the driver can be deposited in the front of the driver-flywheel contact wire of motion.This accumulation proceeds to always and occurs sliding or unsteady phenomenon, and in fact driver-flywheel contact drops to makes frictional force and driving force forfeiture.When this happens, the forfeiture because of the frictional force between the flywheel of driver and its correspondence makes driver lose its originally good driving function.This situation may just take place after several work periods seldom for number.So far, can only be by taking instrument apart, the flywheel of cleaning driver and its correspondence could recover driving force.And the wearing and tearing that this impurity also can accelerator actuator reduce its working life significantly.
Obviously, 5 on driver 1 and its flywheel to contact with driver 9 and its flywheel 12 in fact all be the line contact with 13 contact.During impulse stroke, the contact of these lines round flywheel and along driver towards driver the upper end carry out, therefore driver 1 and 9 and the flywheel 5,12 and 13 of their correspondences between set up contact area.We find, have a best contact area for given flywheel and given driver.This best contact area depends on like this some factors: as making material, the payload of size, driver and the flywheel of instrument or put on the value etc. of the extruding force of driver by flywheel and analog etc.These factors when design one concrete instrument, are easy to be measured out by those skilled in the art.
These factors are not construed as limiting the present invention.However, when on flywheel 5,12 and 13 circumferential groove being set, it is very important keeping best contact area between the driver of each flywheel and its correspondence.This can just can finish with that part of width of 13 each driver that is contacted by widening simply by flywheel 5,12.
As mentioned above, United States Patent (USP) 4519535 is pointed out, annular (circumference) groove that limit one or more and flywheel circumference working face parallels can be set on the circumference working face of flywheel.These grooves provide cavity along driver-flywheel contact wire, give the place of the impurity of piling up to flow.Because the impurity of piling up can go with having, it can not be deposited on driver-flywheel contact-making surface too much, and frictional force is therebetween descended.United States Patent (USP) 4519535 points out that further annular (circumference) groove can not filled up by impurity.
The present invention further discloses, if the one or more grooves that are formed on the flywheel circumference working face become the angle relation with two parallel edges of that flywheel circumference working face, when the contact of these lines around flywheel and along driver when advance in its upper end, these grooves will pass through driver and contact with line between flywheel.As a result, one or more grooves show extruding and cleaning effect on the contact-making surface between driver and flywheel, and the accumulation and the frictional force of impurity reduce thereby more effectively hinder therebetween.And flywheel and driver wear and tear relatively evenly and can not form annular (circumference) ridge edge, the working life that has further prolonged it in drivers.
See also Fig. 3 and Fig. 4 now.Illustrated among Fig. 3 usually with 18 flywheels of representing.Flywheel 18 can be equipped with suitable wheel hub 19 and axle 20.Obviously, these parts of flywheel 18 are not construed as limiting the invention.
Flywheel 18 has the working face 21 of circumferential circle, and as can be seen from Figure 3, it laterally is flat.This working face 21 has two parallel edges 22 and 23.Working face 21 schematically shows with plane form in Fig. 4.One continuous groove 24 is formed in the working face 21, and this can see the most clearly from Fig. 4.In half of the circumference of flywheel 18, this groove 24 is from extending near working face edge 22 near working face edge 23.For second half of flywheel circumference, groove 24 turns back near working face edge 23 from extending near working face edge 22 again.As can be seen, with respect to the working face 21 of flywheel 18, each segmentation of groove 24 is linear.Can know from Fig. 3 and Fig. 4 and to find out that when flywheel rotation one whole circle, groove 24 at first crossed line contact between flywheel and the driver from a direction, crossed the line contact then the other way around.
One as an example and to the present invention not in the example of any limited significance of tool, about 1.938 inches and and have about 0.5 an inch driver logotype of width of the diameter of the flywheel of Fig. 3 and Fig. 4.About 0.565 inch of flywheel face width.About 0.035 inch of the width of groove 24, about 0.06 inch of the degree of depth.The limit of groove 24 is parallel and becomes 16 degree angles approximately.Flywheel is installed in the instrument with driver.After a large amount of work periods, the friction engagement between discovery flywheel and driver can keep and not have impaired.The working face 21 of flywheel 18 and the wearing and tearing of the working face of driver are minimum, do not occur the groove (ridge edge) of circumferential on the working face of driver.
Fig. 5 to Figure 11 shows the structure of other groove of the working face 21 that can be used for flywheel 18.Among Fig. 5, except that groove 25 1 through to the edge 22 and edge 23 of working face 21, groove 25 groove 24 with Fig. 4 basically is identical.The groove 26 of Fig. 6 is similar with 25 to the groove 24 of Fig. 4 and Fig. 5, but groove 26 is full curves and sine wave shape is arranged.If necessary, groove 26 can reach the position near edge 22 and 23 in the mode identical with the groove 24 of Fig. 4.
The embodiment of remaining Fig. 7 to Figure 11 is provided with one or more scroll grooves.Two grooves 27 and 28 are arranged among the embodiment of Fig. 7.Two grooves are identical and extend to working face edge 23 from working face edge 22.Groove 27 and 28 respectively extends half (being half of circumference of flywheel) of the length of about working face 21.Fig. 8 embodiment is similar to Fig. 7, just is provided with the closeer at interval each other scroll groove of more number.
Fig. 9 embodiment adopts single groove 33, and this groove extends to working face edge 23 and is full of the length of entire working surface 21 from working face edge 22.Figure 10 embodiment is provided with two scroll grooves 34 and 35, and they are similar to the groove 33 of Fig. 9.Groove 34 a bit begins on edge 22, with the starting point of groove 35 180 degree or half of working face 21 length of approximately being separated by.
At last, in the embodiment of Figure 11, working face is provided with single groove 36.Groove 36 22 extends to edge 23 from the edge.As can be seen, groove 36 on flywheel around two whole circles.Different with Fig. 4,5 and 6 embodiment, the embodiment of Fig. 7 to Figure 11 only crosses flywheel and contacts with line between driver in a direction.
Obviously, the embodiment of Fig. 4 to Figure 11 only is some examples of usefulness as an example, can also propose other embodiment within the scope of the invention.Important feature is: between each work period of fastener-driving tools, groove is passed through over along the contact wire between flywheel and the driver.
When the electromechanical fastener-driving tools is equipped with two driving flywheels, all be provided with the groove of the above-mentioned type on best two flywheels.Also have, preferably the groove of two flywheels is arranged to such an extent that can clean driver in the opposite direction simultaneously.When for example low inertia roller of single flywheel and support member, linear roller bearing or polytetrafluoroethylene (PTFE) pulley (Teflon block) when being used in combination, there is no need on support member, to establish groove.
In essentiality content scope of the present invention, can also make many variations or change to the present invention.Groove for example of the present invention can be made other any suitable cross section structure, or the like.
