Abstract
The utility model belongs to the technical field of grinding wheel dressers, and relates to a dual-supporting single-point arc dresser, in particular to a device for dressing grinding wheels. The dual-supporting single-point arc dresser comprises a dressing base. An upper rotating shaft is installed at the upper end of a dressing cavity through a bearing, the upper end of the upper rotating shaft is connected with a speed reducer through a coupling, and the upper end of the speed reducer is connected with a driving motor. A lower rotating shaft is installed at the lower end of the dressing cavity through a bearing, and the center line of the lower rotating shaft and the center line of the upper rotating shaft are located in the same straight line. An arc-shaped rotating rocker is arranged in the dressing cavity, and the upper end and the lower end of the rotating rocker are connected with the upper rotating shaft and the lower rotating shaft through jackets. An eccentric sleeve is arranged in a center circular hole of the rotating rocker, and the front end of the eccentric sleeve is connected with a diamond pen. The dual-supporting single-point arc dresser is simple, compact and reasonable in structure, convenient to use, fast to adjust, and high in rotation precision due to the adoption of the upper rotating shaft and lower rotating shaft supporting structure; furthermore, the dual-supporting single-point arc dresser is strong in universality and wide in application range because the grinding wheel dressing radius is adjustable.
Description
Technical field
The utility model relates to a kind of double base single-point grinding wheel arc dresser, specifically for the device of trimming wheel, belongs to dresser technical field.
Background technology
Dresser is that grinding machine is used for the important device of dressing and shaping emery wheel.Generally there are the several methods such as the finishing of single-point diamond pen straight line, circular arc finishing, emery wheel video disc interpolation finishing, emery wheel moulding finishing.In the time that being circular arc, grinding wheel shape generally has three kinds of method for trimming: 1, emery wheel moulding finishing, adopt emery wheel moulding finishing to be applicable to produce in enormous quantities same specification product, in the time that changing, product circular shape just can only change roller, so processing cost is relatively high.In the time of many variety production of small lot, change kind bothers simultaneously; 2, Buddha's warrior attendant video disc interpolation finishing, different cultivars roller does not need to change, and adjusts by changing lathe finishing interpolation parameters.Solve the drawback of above-mentioned the 1st kind of method.But NC Interpolation is the method that adopts straight line to approach circular arc on microcosmic, and sensitivity and overall precision to lathe are had relatively high expectations.In the time that product arc-shaped surface quality is higher, be often difficult to reach requirement.The method is often used in the not too high corase grind occasion of required precision; 3, single-point circular arc finishing, the method is usually used in the finishing of high accuracy abrasive wheel grinding wheel arc, and different circular arcs is easy to adjust reliable.But existing single-point circular arc finishing adopts single support structure, hydraulic oil cylinder driving gyration, finishing poor rigidity, easily causes wheel vibration and affects product quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of double base single-point grinding wheel arc dresser is provided, and for the circular arc finishing of large emery wheel, has rotating accuracy high, adjusts fast the feature of highly versatile.
The technical scheme providing according to the utility model, a kind of double base single-point grinding wheel arc dresser comprises finishing base, finishing base one side is provided with the finishing chamber of circular arc, it is characterized in that: install gyroaxis in finishing upper end, chamber by bearing, rotating shaft last time upper end is by shaft coupling connection reducer, and decelerator upper end connects drive motors.Gyroaxis under installing by bearing in finishing lower end, chamber, the centerline of lower gyroaxis and rotating shaft last time is in same straight line.In finishing chamber, be provided with the revolution fork of circular arc, the two ends up and down of revolution fork connect rotating shaft last time and lower gyroaxis by chuck.In revolution fork center hole, be provided with eccentric bushing, eccentric bushing front end connects diamond pen.
Preferably, drive motors adopts AC revolution drive motors.
Preferably, the lock-screw that eccentric bushing connects by side is locked in revolution fork center hole.
Preferably, the eccentric bushing rear end adjusting handle that is threaded, is provided with differential spring between adjusting handle and eccentric bushing.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, adopts upper and lower rotation shaft supporting structure, and rotating accuracy is high; Easy to use, adjust quick; Crushing radius is adjustable, highly versatile, and the scope of application is wide.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model partly cuts open figure.
Fig. 3 is A place enlarged drawing in Fig. 2.
Under description of reference numerals: 1-finishing base, 2-, gyroaxis, 3-revolution fork, 4-diamond pen, 5-adjusting handle, 6-lock-screw, 7-eccentric bushing, 8-rotating shaft last time, 9-shaft coupling, 10-decelerator, 11-drive motors, 12-differential spring, 13-motor case, 14-repair chamber.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Fig. 1 ~ 3, the utility model mainly comprises finishing base 1, and finishing base 1 one sides are provided with the finishing chamber 14 of circular arc.
Install gyroaxis 8 in finishing 14 upper ends, chamber by bearing, rotating shaft last time 8 upper ends are by shaft coupling 9 connection reducers 10, and decelerator 10 upper ends connect drive motors 11.Described drive motors 11 adopts accurate small-sized AC revolution drive motors, and decelerator 10 adopts the precision speed reduction device of large reduction of speed ratio, has guaranteed the even running in the time turning round compared with low speed of rotating shaft last time 8, and nothing is creeped, jitter phenomenon, meets high-quality emery wheel finishing requirement.
Gyroaxis 2 under installing by bearing in finishing 14 lower ends, chamber, the centerline of lower gyroaxis 2 and rotating shaft last time 8 is in same straight line.
In finishing chamber 14, be provided with the revolution fork 3 of circular arc, the two ends up and down of revolution fork 3 connect rotating shaft last time 8 and lower gyroaxis 2 by chuck.In revolution fork 3 center holes, be provided with eccentric bushing 7, eccentric bushing 7 front ends connect diamond pens 4, and the eccentric bushing 7 rear ends adjusting handle 5 that is threaded, is provided with differential spring 12 between adjusting handle 5 and eccentric bushing 7.Adjusting handle 5 can drive the diamond pen 4 on eccentric bushing 7 to move forward and backward along revolution fork 3 center holes, thereby regulates the finishing radius of emery wheel.The lock-screw 6 that described eccentric bushing 7 connects by side is locked in revolution fork 3 center holes.
Operation principle of the present utility model is: in the time of work, emery wheel is positioned at finishing chamber 14, carries out circular arc finishing by diamond pen 4, and the position of diamond pen 4 can regulate, thereby realizes the finishing of different radii emery wheel, highly versatile, and the scope of application is extensive.Adopt upper and lower rotation shaft supporting structure, rotating accuracy is high.
