Description

Clamping fixture for processing excircle of hard alloy top hammer Technical Field The utility model relates to the technical field of top hammer processing, in particular to a clamping fixture for processing an outer circle of a hard alloy top hammer. Background The hard alloy top hammer is an indispensable key consumable in the synthesis of the superhard material, the quality of the hard alloy top hammer determines the synthesis quality of the superhard material, and meanwhile, the processing efficiency of the hard alloy top hammer also influences the price of the top hammer and the production cost of the superhard material. The hard alloy top hammer structure comprises a top surface, four large inclined surfaces, four small inclined surfaces, an outer circle and a bottom surface, wherein the top surface, the four large inclined surfaces and the four small inclined surfaces are called nine surfaces together, when the hard alloy top hammer is machined, firstly, the outer circle of the hard alloy top hammer needs to be ground, due to the particularity of the hard alloy top hammer structure, when a grinding wheel longitudinal machine tool is used for machining the outer circle of the hard alloy top hammer, a special clamping fixture is required to be installed on the machine tool, at present, the clamping fixture is usually a top hammer large inclined surface profiling fixture, when clamping, the hard alloy top hammer large inclined surface is matched with the top hammer large inclined surface profiling fixture, and the other end of the clamping fixture is tightly pressed against the hard alloy top hammer bottom surface through a machine tool tailstock so as to achieve the fixing effect, however, at present, the hard alloy top hammer blank is required to be sintered at high temperature after being formed through powder, the hard alloy top hammer blank is deformed to different degrees, namely, different degrees or upturned, when the hard alloy top hammer and the top hammer large inclined surface profiling fixture cannot be completely matched, and a gap exists when clamping is caused, the hard alloy top hammer and the hard alloy top hammer large inclined surface profiling fixture cannot be firmly clamped, and the gap is required to be formed, at this moment, the gap is required to be overcome. But at present, the mode of this kind of backing paper is very loaded down with trivial details, and paper can be wetted by grinding fluid and throw away when following carbide top hammer high-speed rotatory processing, lead to the top hammer clamping in the processing not hard alloy top hammer to become flexible, and then lead to the carbide top hammer that drops to take place in the course of working, the irregular collision and grinding can take place with the emery wheel for the carbide top hammer that drops, can not only lead to the fact carbide top hammer product to scrap like this, can also cause the damage to the machine tool simultaneously, especially in the processing large-scale top hammer in-process more take place the clamping not hard up and lead to the accident that top hammer dropped, this kind of top hammer big inclined plane profile modeling anchor clamps cooperation backing paper clamping mode production efficiency is lower, there is higher production processing risk simultaneously, easily cause the processing accident to take place. Disclosure of utility model Based on the problems existing in the prior art, the utility model aims to provide a clamping fixture for processing the excircle of a hard alloy top hammer. The technical scheme includes that the clamping fixture for processing the outer circle of the hard alloy top hammer comprises a profiling fixture main body, wherein a plurality of profiling claws which are uniformly distributed along the circumferential direction are arranged at the upper end of the profiling fixture main body and form a containing cavity together, claw head inclined planes which are matched with the shape of the large inclined plane of the top hammer are arranged on the profiling claws, and telescopic fixing plates and adjusting assemblies for adjusting the positions of the telescopic fixing plates to enable the telescopic fixing plates to be tightly attached to the large inclined plane of the top hammer are further arranged at the top ends of the profiling claws. The adjusting component comprises a limit screw for propping up the telescopic fixed plate to adjust the position of the telescopic fixed plate and a guide column for limiting the moving direction of the telescopic fixed plate. Threaded holes and guide holes penetrating through the outer circular surface and the inner side surface of the profiling claw are formed in the top end of the profiling claw. One end of the guide post is fixedly connected to the telescopic fixed plate, and the other end of the guide post is positioned in the guide hole on the profiling claw. The tail end of the limit screw penetrates thro
