The bottom plate is provided with at least one set of clamp component, the clamp component comprises two fixing plates, an edge-eat pin and a locating pin, the edge-eat pin and the locating pin are arranged between two locating plates, the locating plates are fixed on the bottom plate through bolts, the locomotive brake shoe is arranged in the inner annular edge of the bottom plate, the locating pin is inserted in a locating hole in the locomotive brake shoe and fixed through the two fixing plates, and the edge-eat pin is located on one side of the locomotive brake shoe to assist in locating. Compared with the prior art, the elevator traction locomotive brake shoe machining clamp has the advantages of being simple in structure, capable of improving machining precision, and the like.
Description
Technical field
The present invention relates to a kind of fixture, especially relate to a kind of elevator traction locomotive brake shoe clamp for machining.
Background technology
Brake shoe is conventional parts in braking machinery, for some circular arc brake shoes, in order to ensure braking effect, require the working face of the brake shoe after processing, installation must ensure enough precision, but in process, especially in assembly welding process, after brake shoe is heated, easily deform and cannot use, causing decrease in yield.
Utility model patent ZL200920063393.5 discloses a kind of fixture for making brake shoe, comprises an arc sample circle identical with brake shoe working face, on arc sample circle, multiple clamps is set, clamp be activity movably.This fixture is in order effectively to prevent the distortion of brake shoe in assembly welding process, adopt the arc sample circle identical with brake shoe working face, be used in conjunction with removable clamp, although reduce to a certain extent distortion,, locate inaccurate, easily mobile, especially the accumulated error that multiple clamping produces affects machining accuracy, and production efficiency is low, and labour intensity is high.
Summary of the invention
Object of the present invention is exactly to provide a kind of simple in structure in order to overcome the defect that above-mentioned prior art exists, and can improve the elevator traction locomotive brake shoe clamp for machining of machining accuracy.
Object of the present invention can be achieved through the following technical solutions: a kind of elevator traction locomotive brake shoe clamp for machining, comprise one with the circular base plate of the brake watt identical arc of working face, it is characterized in that, on described base plate, disperse to be provided with at least one group of clamp assembly, this clamp assembly comprises two fixed heads, and the pin limit arranging between two location-plates pin and alignment pin, described location-plate is bolted on base plate, car brake shoe is arranged on ring limit in base plate, locating hole on car brake shoe inserts in alignment pin, and fix by two fixed heads, described pin limit pin is positioned at car brake shoe auxiliary positioning on one side.
Two described location-plates be provided with can around bolt rotate and can before and after slide waist-shaped hole, according to the position adjustments location-plate of car brake shoe, and be bolted.
Described alignment pin is cylindrical shape, matches with the locating hole on 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 2-6 group, and scattering device is on circular base plate.
Described fixture clamps small size workpiece, ensures that small size workpiece car goes out orthodrome, and the cambered surface size of guarantee circular arc and cambered surface are to the distance (ensureing that cambered surface arrives the distance at work axis hole center) of alignment pin.
Compared with prior art, the present invention is simple in structure, and accurate positioning can avoid repeatedly installing the error causing, improve machining accuracy, reduce labour intensity, and be provided with many group clamp assemblies simultaneously, can disposablely clamp multiple workpiece, and can process simultaneously, working (machining) efficiency is high, and middle without dismounting after disposable clamping, thereby has ensured the machining accuracy of multiple workpiece.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, a kind of elevator traction locomotive brake shoe clamp for machining, comprise one with the circular base plate 5 of the brake watt identical arc of working face, on described base plate 5, disperse to be provided with at least 4 group clamp assemblies, every group of clamp assembly comprises two fixed heads 1, and the pin limit pin 3 and the alignment pin 4 that between two location-plates 1, arrange, described location-plate 1 is fixed on base plate 5 by bolt 2, location-plate 1 be provided with can around bolt rotate and can before and after slide waist-shaped hole, can locate according to the position adjustments location-plate 1 of car brake shoe, and fixing by bolt 2.Described alignment pin 4 is cylindrical shape, matches with the locating hole on 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.
Car brake shoe is arranged on ring limit in base plate, and the locating hole on car brake shoe inserts in alignment pin, and fixes by two fixed heads, and described pin limit pin is positioned at car brake shoe auxiliary positioning on one side.
Described clamp assembly is provided with 2-6 group, and scattering device is on circular base plate.
Fixture clamps small size workpiece, even if can ensure that workpiece size is very little simultaneously, but can, at fixedly get off out 700 degree and the above orthodrome of this fixture, ensure the cambered surface size of circular arc, thereby can ensure that in addition cambered surface arrives the distance guarantee cambered surface of alignment pin to the distance at work axis hole center.
