Abstract
The present invention relates to a portable electric spot-facing chamfering machine. It is characterized by that it is formed from the following several portions: machine frame; magnetic block clamping device which is mounted under the machine frame, used for clamping workpiece and is equipped with a magnetic flux switch and spot-facing mechanism which is mounted over the machine frame. Said invention also provides its working principle and concrete operation method.
Description
Technical field
The present invention relates to a kind of portable electric tool, particularly a kind of hand-held electric spot-facing beveler.
Background technology
At present, touch manufacturings such as tool five metals at machinery, the metallic element that is processed all is connected with rivet by screw, so on metallic element, be drilled with many big and small holes, the hole that processes with drill bit on drilling machine all has burr, burr, in order to reach the assembly technology requirement, 45 ° spot-facing chamfered must be carried out in these holes that have the burr burr, also be on drilling machine, to carry out this procedure of chamfering at present, operation is to be the chamfering about (0.1-3.5) * 45 ° processing the nominal standard size on the end face in hole by the size in hole, particularly during through hole, two-sidedly all will carry out chamfer machining, chamfering will be carried out more bit change on drilling machine, displacement, centering, work steps such as locking board anchor clamps, operation is trouble comparatively, lose time very much again, and taken a large amount of production times of lathe, big at operating process Fraquent start motor power consumption, when adopting large-sized drill machine to finish chamfer machining, because drilling machine cost height is so processing charges are also higher.
Summary of the invention
The objective of the invention is to design a kind of hand-held electric spot-facing beveler, it has simple in structure, operate light, production efficiency height, characteristics such as crudy is good.
The present invention realizes with following technical scheme: this spot-facing beveler is by frame, the spot-facing mechanism of playing clamping workpiece magnetic patch clamping device that use and that have Flux switch (inhaling piece but its structure is equivalent to the magnet of the switch magnetic flow of being joined on the used usually dial gauge instrument of metalworking workshop) and being installed on the frame top that is installed on frame below forms, and wherein spot-facing mechanism is again by the guide pillar that is connected successively, pivot bush unit is on guide pillar and be used for the support spring of support guide pin bushing, guide pin bushing, the motor of fixedlying connected with guide pin bushing one side, gear reduction box and counterbit cutter constitute.
In technical solution of the present invention, on described frame, also be fixed with a spacing bolt column of using, on bolt column, be connected with and can touch mutually to control the stop nut regulated of cutting output with guide pin bushing.
In technical solution of the present invention, have the scale of ten five equilibriums on described (adjusting spot-facing working depth) spacing surface with adjustable nut, as be carved into ten five equilibrium lines, every line value equals 0.1mm, with the degree of depth that the handled easily workman regulates spot-facing processing, accomplish accurately spacing.
In technical solution of the present invention, also be equipped with a movable left handle of amounting in the outside of described frame (left-external side), also be equipped with a movable right handle of amounting in the outside (the right outside) of motor.
Use principle method of the present invention is as follows: this machine can utilize processed workpiece as platform, but the magnetic patch magnetic force of the switch magnetic flow that will use as anchor clamps is as fastening force, spot-facing mechanism is fastened on the workpiece with magnetic force absorption, the circular hole on the workpiece is carried out spot-facing processing.With reference to accompanying drawing, its specific operation process is as follows: the available right hand down workpiece pressing of right handle of holding with a firm grip, force counterbit (head) to aim at the center of circular hole to be processed, the left hand left handle of holding with a firm grip, and open Flux switch, this moment, whole spot-facing mechanism was fixed on the workpiece by magnetic force, loosened the right hand, make counterbit (head) leave workpiece a little, start power switch simultaneously, motor drives the counterbit head by gear reduction box and rotates, and this moment is by the bottom right handle, make the counterbit cutting workpiece, by the spot-facing time of an about 0.5-3 in hole of the general processing of size second in hole, when reaching the spacing position of being set up, just loosen the right hand, the powered-down switch, under the effect of support spring, motor and spot-facing mechanism are pushed up from workpiece the closed magnetic flux switch, just finish the spot-facing processing in this machine hole, also complete machine can be moved on workpiece simultaneously next hole is processed.Counterbit of the present invention (head) can adopt 90 ° of taper multiple-cutting-edge counterbits that the automatic centering effect is arranged, and as when cutter departs from the center, agrees with monolateral load resistance, will pass the center, hole to counterbit under the downforce effect.The cutting output adjusting nut can be adjusted the spot-facing chamfering degree of depth.
Compare with the spot-facing beveler of the big drilling machine of prior art, have simple to operate, easy to use, work efficiency improves more than ten times, and the chamfer machining face that adopts counterbit to process is highly polished, and no burr, the degree of depth are accurate, size is unified, it is small and exquisite in light weight that complete machine also has structure, good energy-conserving effect, the low advantages such as (quite electric tool prices) of cost cost.
Description of drawings
Fig. 1 is a kind of overall structure schematic diagram of the present invention.
The specific embodiment
With reference to accompanying drawing as can be known, when the present invention makes in specific design, its structure comprises frame 5 and is installed on the magnetic that has Flux switch 1 (iron) the piece clamping device 4 of frame 5 belows, frame 5 passes on left hinge 3 and is provided with the left handle 2 that can amount to, also add a movable right handle 16 of amounting to (connecting) by hinge pin axle 15 in the right outside of motor 12, frame 5 upper fixed have guide pillar 10, movable sleeve is connected to spring 8 and guide pin bushing 9 and clamp nut 11 on the guide pillar 10, motor 12 by bolt 14 with after the gear reduction box 17 that is positioned at the motor front end is connected, be fixedly installed in a side of guide pin bushing 9 again by threaded connector 13, and constitute spot-facing mechanism together, support spring 8 should support the whole spot-facing mechanism that comprises motor weight, the output shaft of reduction gear box 17 connects counterbit head 18 with Morse's taper, just can on workpiece 19, carry out the spot-facing chamfer machining, the stopping means that the caging bolt post 7 that can regulate the spot-facing depth dimensions and adjusting nut 6 thereof constitute also is housed on frame 5, on the circumference of the upper surface of adjusting nut 6, be carved with the scale of ten five equilibrium lines, spot-facing adds man-hour, guide pin bushing 9 can touch with adjusting nut 6 in folding process, plays the position-limiting action of spot-facing working depth.
