Bidirectional piston type pneumatic clamp for combined machining of automobile air conditioner compressor shell

Abstract

The invention discloses a two-way piston type automobile air conditioner compressor shell combination machining pneumatic clamp which comprises a clamp body, a tensioning mechanism, a jacking mechanism and a rotating mechanism, the clamp body and the tensioning mechanism are installed on a numerical control index plate, the numerical control index plate and the jacking mechanism are installed on a machine tool workbench, and the tensioning mechanism and the jacking mechanism are oppositely arranged. Tensioning and jacking of a workpiece are automatically controlled, the tensioning force and the jacking force are consistent in direction, acting force is uniform, clamping time is shortened, production efficiency is improved, labor intensity of workers is reduced, and meanwhile the safety mistake-proof function that the workers forget to clamp the pressing plate is achieved; during rotation angle machining, the tensioning rotation structure and the jacking rotation structure can work, and the structure is simple, practical and reliable; the product is clamped at one time, so that the flatness and parallelism quality of the air suction and exhaust port parts and the mounting lugs of the front and rear cylinder bodies are ensured; quick remodeling can be realized, the production efficiency is improved, and processing switching of different products can be realized only by replacing the positioning plate during remodeling.

Description

technical field [0001] The invention relates to the technical field of processing automobile air-conditioning compressor shells, in particular to a pneumatic clamp for combined processing of two-way piston type automobile air-conditioning compressor casings. Background technique [0002] The cylinder block is the most important and complex part in the automotive air-conditioning compressor, especially the suction and exhaust sealing performance is very high. The existing processing technology of the front cylinder block and the rear cylinder block of the two-way piston type automotive air-conditioning compressor shell, the processing technology of the suction and exhaust holes, generally adopts the manual operation of the single shell (front cylinder block or rear cylinder block) by the operator. Place the CNC indexing table (fourth axis turntable) on the tooling with screws, and the pressure plate to press the workpiece tightly. Due to the manual operation, the labor inten...

AI Technical Summary

Problems solved by technology

Due to the manual operation, the labor intensity of the workers is increased, and the production efficiency is reduced. At the same time, the front cylinder body and the rear cylinder body are processed with mounting ears, so it is difficult to ensure the parallelism of the suction and exhaust holes, and the consistency is poor. As a result, the suction and exhaust pressure plates cannot be sealed when assembling, which is easy Leakage and difficult installation when installing the compressor on the whole vehicle, the product rework rate or scrap rate is high, and it is easy to cause the quality of the car air-conditioning compressor to decline
