Description
Technical field
The utility model relates to motor vehicle brake shoe manufacturing technology, is related specifically to a kind of motor vehicle brake shoe assembly chamfering clamp.
Background technology
Drum brake, when braking, usually drives friction facing outwards movement by brake-shoe, makes friction facing and brake drum inwall produce strong friction, absorbs energy, finally brakes.Due to brake shoe assembly drive liner outwards move time, the front end of friction facing contacts suddenly brake drum inwall, and now brake drum is in High Rotation Speed state, produces sharp pounding between the two, and then produces so-called initial brake noise.For solving initial brake noise problem during brake shoe assembly skidding, usually the front end of friction facing being ground off a fritter, making friction facing front end be the breach of α at an angle relative to tangent line shape, being usually referred to as chamfering.Prior art motor vehicle brake shoe assembly chamfering method adopts hand-guided to carry out chamfering to liner usually, the operation technique of operator and motive force size affect very large on friction facing chamfer dimesion, not only complicated operation, labour intensity are larger, further, after chamfer machining, the dimensional accuracy of friction facing and uniformity are all difficult to ensure.Obviously, it is comparatively large that prior art motor vehicle brake shoe assembly chamfering method also exists complicated operation, labour intensity, and after chamfer machining, the dimensional accuracy of friction facing and uniformity are all difficult to the problems such as guarantee.
Summary of the invention
For the complicated operation, the labour intensity that solve the existence of prior art motor vehicle brake shoe assembly chamfering method are larger, after chamfer machining, the dimensional accuracy of friction facing and uniformity are all difficult to the problems such as guarantee, the utility model proposes a kind of motor vehicle brake shoe assembly chamfering clamp.The utility model motor vehicle brake shoe assembly chamfering clamp, comprises, base, mandrel, bearing, rotary body, fastening bolt, pressing plate and butterfly nut; Described mandrel is arranged on base center, and rotary body is fixed on mandrel by bearing; The excircle dimension of described rotary body and the inner circle on the brake-shoe edge of a wing match, and the width on thickness and the brake-shoe edge of a wing matches; The two groups of alignment pins matched with brake-shoe web mounting-positioning holes are symmetrically arranged with in the outer face of rotary body, and the link stopper of restriction emery wheel shift position; Further, be also symmetrically arranged with fastening bolt in the outer face of rotary body, pressing plate is sleeved on fastening bolt, and butterfly nut spinning is on fastening bolt.
Further, described bearing is bearing group, and namely two bearings are fixed on mandrel by lining interval, and rotary body is sleeved on two bearings.
Further, the set bolt of pressing plate bottom is also set with return spring.
The Advantageous Effects of the utility model motor vehicle brake shoe assembly chamfering clamp is dimensional accuracy and the uniformity that can ensure brake shoe assembly friction facing chamfering, improves the quality of friction facing chamfer machining, efficiency and yield rate.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of brake shoe assembly chamfering;
Accompanying drawing 2 is front elevational schematic of the utility model motor vehicle brake shoe assembly chamfering clamp;
Accompanying drawing 3 is schematic top plan view of the utility model motor vehicle brake shoe assembly chamfering clamp.
Below in conjunction with drawings and the specific embodiments, the utility model motor vehicle brake shoe assembly chamfering clamp is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic diagram of brake shoe assembly chamfering, as seen from the figure, for solving initial brake noise problem during brake shoe assembly skidding, usually the front end of friction facing is ground off a fritter, make friction facing front end be the breach of α at an angle relative to tangent line shape, be usually referred to as chamfering.Prior art motor vehicle brake shoe assembly chamfering method adopts hand-guided to carry out chamfering to liner usually, the operation technique of operator and motive force size affect very large on friction facing chamfer dimesion, not only complicated operation, labour intensity are larger, further, after chamfer machining, the dimensional accuracy of friction facing and uniformity are all difficult to ensure.Obviously, it is comparatively large that prior art motor vehicle brake shoe assembly chamfering method also exists complicated operation, labour intensity, and after chamfer machining, the dimensional accuracy of friction facing and uniformity are all difficult to the problems such as guarantee.
Accompanying drawing 2 is front elevational schematic of the utility model motor vehicle brake shoe assembly chamfering clamp, and accompanying drawing 3 is schematic top plan view of the utility model motor vehicle brake shoe assembly chamfering clamp, in figure, 1 is base, and 2 is mandrel, and 3 is bearing, 4 is rotary body, 5 is fastening bolt, and 6 is pressing plate, and 7 is butterfly nut, 8 is alignment pin, 9 is link stopper, and 10 is emery wheel, and 11 is return spring.As seen from the figure, the utility model motor vehicle brake shoe assembly chamfering clamp, comprises, base 1, mandrel 2, bearing 3, rotary body 4, fastening bolt 5, pressing plate 6 and butterfly nut 7; Described mandrel 2 is arranged on base 1 center, and rotary body 4 is fixed on mandrel 2 by bearing 3; The excircle dimension of described rotary body 4 and the inner circle on the brake-shoe edge of a wing match, and the width on thickness and the brake-shoe edge of a wing matches; The two groups of alignment pins 8 matched with brake-shoe web mounting-positioning holes are symmetrically arranged with in the outer face of rotary body 4, and the link stopper 9 of restriction emery wheel 10 shift position; Further, be also symmetrically arranged with fastening bolt 5 in the outer face of rotary body 4, pressing plate 6 is sleeved on fastening bolt 5, and butterfly nut 7 spinning is on fastening bolt 5.During concrete use, first friction facing is bonding or be riveted on outside the brake-shoe edge of a wing, the locating hole of the installation web of brake shoe assembly is sleeved on the alignment pin of rotary body outer face, because the excircle dimension of rotary body and the inner circle on the brake-shoe edge of a wing match, the width on thickness and the brake-shoe edge of a wing matches; Further, match at alignment pin and brake-shoe web mounting-positioning holes, can ensure that brake shoe assembly is accurately positioned in rotary body outer rim, now, pressing plate on set bolt is just in time in the middle part of brake-shoe web, screws wing bolt, brake shoe assembly can be fixed on rotary body.Open emery wheel, spinning rotary body, be fixed on the brake shoe assembly spinning thereupon on rotary body, emery wheel carries out grinding to the termination of friction facing, and stops when emery wheel moves to baffle plate, makes its angulation be the breach of α, i.e. chamfering.Further, ensure that precision and the uniformity of chamfer dimesion.Be symmetrical arranged because alignment pin, pressing plate etc. are, alternately brake shoe assembly can be installed, and carry out chamfer machining.For ensureing the stationarity of rotary body, the bearing of fixing rotary body is bearing group, and namely two bearings are fixed on mandrel by lining interval, and rotary body is sleeved on two bearings.Thus, the stability of rotary body is added.For convenience of clamping brake shoe assembly, the set bolt of pressing plate bottom is set with return spring, after chamfer machining completes, unclamps butterfly nut, pressing plate upwards lifts under the effect of return spring, facilitates taking-up and the placement of brake shoe assembly.Obviously, due to adopt first friction facing is bonding or riveted joint after carry out chamfer machining again, the efficiency of chamfer machining and yield rate are all largely increased.
Obviously, the Advantageous Effects of the utility model motor vehicle brake shoe assembly chamfering clamp is dimensional accuracy and the uniformity that can ensure brake shoe assembly friction facing chamfering, improves the quality of friction facing chamfer machining, efficiency and yield rate.
