Abstract

The utility model relates to an elevator traction machine brake shoe machining fixture which comprises an annular bottom plate with the same arc shape with a work face of a machine brake shoe. At least one set of fixture component is arranged on the bottom plate in a scattered mode, each fixture component comprises two fixing plates and side pins and positioning pins between two positioning plates, wherein the positioning plates are fixed on the bottom plate through bolts, the machine brake shoe is arranged on the inner ring edge of the bottom plate, the positioning pins are inserted in positioning holes in the machine brake shoe, the machine brake shoe is fixed through the two fixing plates, and the side pins are located on one side of the machine brake shoe for auxiliary positioning. Compared with the prior art, the elevator traction machine brake shoe machining fixture has the advantages of being simple in structure and capable of improving machining precision.

Description

A kind of elevator traction locomotive brake shoe clamp for machining
Technical field
The utility model relates to a kind of anchor clamps, especially relates to a kind of elevator traction locomotive brake shoe clamp for machining.
Background technology
Brake shoe is parts commonly used in the braking machinery, for some circular arc brake shoes, in order to guarantee braking effect, the working face of the brake shoe after requiring to process, install must guarantee enough precision, but in process, especially in the assembly welding process, deform easily after brake shoe is heated and can't use, cause decrease in yield.
Utility model patent ZL200920063393.5 discloses a kind of brake shoe clamp for machining, comprises an arc sample circle identical with the brake shoe working face, on arc sample circle a plurality of clamps is set, clamp be activity movably.These anchor clamps are in order to prevent the distortion of brake shoe in the assembly welding process effectively, adopted the arc sample circle identical with the brake shoe working face, be used removable clamp, though reduced distortion to a certain extent,, locate inaccurate, move easily, especially the accumulated error of multiple clamping generation influences machining accuracy, and production efficiency is low, the labour intensity height.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simple in structure for the defective that overcomes above-mentioned prior art existence, can improve the elevator traction locomotive brake shoe clamp for machining of machining accuracy.
The purpose of this utility model can be achieved through the following technical solutions: a kind of elevator traction locomotive brake shoe clamp for machining, comprise a circular base plate with the brake watt identical arc of working face, it is characterized in that, disperse to be provided with at least one group of clamp assembly on the described base plate, this clamp assembly comprises two fixed heads, and the pin limit that is provided with between two location-plates pin and alignment pin, described location-plate is by being bolted on the base plate, the car brake shoe is arranged on ring limit in the base plate, locating hole on the car brake shoe inserts in the alignment pin, and fix by two fixed heads, described pin limit pin is positioned at car brake shoe assist location on one side.
Described two location-plates be provided with can around bolt rotate and can before and after the waist-shaped hole that slides, according to the position adjustments location-plate of car brake shoe, and pass through bolting.
Described alignment pin is cylindrical shape, is complementary with locating hole on the car brake shoe.
Described pin limit pin is cylindrical shape, and is being provided with a straight flange near car brake shoe one side, guide car brake shoe location.
Described clamp assembly is provided with the 2-6 group, disperses to be arranged on the circular base plate.
Described anchor clamps clamp small size workpiece, guarantee that the small size workpiece car goes out orthodrome, and the cambered surface size of assurance circular arc and cambered surface are to the distance (guaranteeing that promptly cambered surface arrives the distance at work axis hole center) of alignment pin.
Compared with prior art, the utility model is simple in structure, and accurate positioning can avoid repeatedly installing the error that causes, improve machining accuracy, reduce labour intensity, and be provided with many group clamp assemblies simultaneously, can disposablely clamp a plurality of workpiece, and can process simultaneously, the working (machining) efficiency height, and need not dismounting in the middle of behind disposable clamping, thus guaranteed the machining accuracy of a plurality of workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, a kind of elevator traction locomotive brake shoe clamp for machining, comprise a circular base plate 5 with the brake watt identical arc of working face, disperse to be provided with at least 4 group clamp assemblies on the described base plate 5, every group of clamp assembly comprises two fixed heads 1, and the pin limit that is provided with between two location-plates 1 pin 3 and alignment pin 4, described location-plate 1 is fixed on the base plate 5 by bolt 2, location-plate 1 be provided with can around bolt rotate and can before and after the waist-shaped hole that slides, according to position adjustments location-plate 1 location of car brake shoe, and fixing by bolt 2.Described alignment pin 4 is cylindrical shape, is complementary with locating hole on the car brake shoe.Described pin limit pin 3 is cylindrical shape, and is being provided with a straight flange near car brake shoe one side, guide car brake shoe location.
The car brake shoe is arranged on ring limit in the base plate, and the locating hole on the car brake shoe inserts in the alignment pin, and fixes by two fixed heads, and described pin limit pin is positioned at car brake shoe assist location on one side.
Described clamp assembly is provided with the 2-6 group, disperses to be arranged on the circular base plate.
Anchor clamps clamp small size workpiece, even can guarantee that workpiece size is very little simultaneously, but the orthodrome more than can reaching at 700 degree of fixedly getting off out of these anchor clamps guarantees the cambered surface size of circular arc, thereby can guarantee that in addition cambered surface arrives the distance of the distance assurance cambered surface of alignment pin to work axis hole center.
