Compressor cylinder block machining fixture

Abstract

The invention discloses a compressor cylinder block machining fixture. The compressor cylinder block machining fixture comprises vertical plates symmetrically and fixedly arranged at the two ends of abottom plate. A rotary plate is erected on the vertical plates through a rotary shaft and can rotate around the rotary shaft. A locating flange is movably arranged on the top end face of the rotary plate. The edge of the locating flange is pressed and fixed through pressing blocks fixedly arranged on the rotary plate. A locating part is connected to the middle of the locating flange through bolts. A telescopic cylinder is mounted at the bottom end of the rotary plate. A piston rod of the telescopic cylinder penetrates through the locating part and the locating flange in sequence to be connected with a connecting screw rod of the rotary plate. A pressing plate is clamped to the portion, under a nut, of the connecting screw rod. The compressor cylinder block machining fixture is high in universality. The repeated locating precision, production efficiency and machining quality are improved. The clamping time is shortened. The labor intensity of works is reduced. The number of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of machining of automobile air-conditioning compressors, in particular to a processing fixture used for cylinder blocks of automobile air-conditioning compressors. Background technique [0002] The cylinder block is the most important and complex part in the automotive air-conditioning compressor. Because the appearance and shape of different cylinder blocks are very different, the internal processing dimensions are also very different, especially there are many inclined holes inside the cylinder block that need to be processed. At present, in the traditional processing technology, the operator manually drills the holes, and the inclined holes are all drilled manually by the operator on the tooling. Because they are all manually operated, the labor intensity of the workers is increased, the production efficiency is reduced, and the quality of the processed holes is difficult to guarantee; in addition, be...

AI Technical Summary

Problems solved by technology

Because they are all manually operated, the labor intensity of the workers is increased, the production efficiency is reduced, and the quality of the processed holes is difficult to guarantee; in addition, because the angle of the inclined hole is drilled by the hand, the position of the exit of the inclined hole is not uniform. As a result, the product scrap rate is very high; again, due to the instability of manual operation, the accuracy and quality of the inclined hole cannot be unified, which will easily cause the quality of the automotive air-conditioning compressor to decline
