Clamp for machining rear cover of automobile air conditioning compressor

Abstract

The invention discloses a clamp for machining a rear cover of an automobile air conditioning compressor. The clamp comprises a connecting seat fixedly arranged on a connecting flange, a positioning disc is arranged in the middle of the top end of the connecting seat, and the positioning disc is correspondingly and fixedly provided with a limiting pin and a supporting column, wherein the limiting pin and the supporting column are used for positioning a rear cover workpiece; and pressing devices for pressing the rear cover workpiece are arranged in the positions, located on the outer side of thepositioning disc, of the connecting seat. According to the clamp for machining the rear cover of the automobile air conditioning compressor, the pressing devices on the left side and the right side clamp the rear cover workpiece at the same time, stress is uniform, and the pressing point positions can be freely adjusted; the clamp is adaptive to the rear cover workpieces of different sizes, so that universality is high; and furthermore, the functions of further improving repeated positioning precision, improving production efficiency, reducing clamping time and the number of times, reducing labor intensity of workers and reducing machining procedures and personnel are achieved.

Description

technical field [0001] The invention relates to the technical field of machining of automobile air-conditioning compressors, in particular to a fixture used for machining the back cover of the automobile air-conditioning compressor. Background technique [0002] The back cover is the most important and complicated part of the car air-conditioning compressor. Because the appearance of different back covers is very different, the internal processing size is also very different, especially there are many oblique holes inside the back cover that need to be processed. At present, the traditional processing technology is manually drilled and tapped by the operator, and the inclined hole is drilled and tapped 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, because the angle of the inc...

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 manually drilled, the position of the exit of the inclined hole is not uniform, resulting in The product scrap rate has always been high; again, due to the instability of manual operation, it is impossible to achieve uniformity in the position of the internal thread of the hole, and it is also impossible to achieve uniformity in the accuracy and quality of the inclined hole, which will easily cause the quality of the automotive air-conditioning compressor to decline
