Transmission shaft device for automobile air-conditioning compressor suction performance testing equipment

Abstract

The invention provides a transmission shaft device for automobile air-conditioning compressor suction performance testing equipment. The transmission shaft device comprises a working table, and a transmission shaft structure, a driving head, a dodecagonal head and a main shaft. The transmission shaft device has the beneficial effects that the transmission shaft device is matched with a compressormain shaft for pumping through a dodecagonal head thread tightening mode, a traditional buckling spline joint mode is replaced, the problem of the abrasion and damage of the compressor main shaft dueto the fact that a buckling key groove structure is effectively solved, the abrasion and damage of the compressor main shaft key groove part due to the fact that the buckling key groove structure areavoided, and the percent of pass of compressor products is improved; and meanwhile, the replacement of easily-damaged parts of the testing equipment is reduced, it is ensured that the automobile air-conditioning compressor suction performance is efficiently and smoothly tested, the using effect is good, and the popularization is facilitated.

Description

technical field [0001] The invention relates to the field of transmission shaft devices, in particular to a transmission shaft device used in equipment for testing the suction performance of automobile air-conditioning compressors. Background technique [0002] At present, automotive air-conditioning compressors are common parts in modern automotive refrigeration (heating) equipment. It is particularly important to check the performance index and check the matching degree between the car air conditioning system and the compressor. Among them, the detection of the suction performance of the automobile air-conditioning compressor is an indispensable link, which plays an important role in improving the qualified rate of compressor products and ensuring the production quality of products.

AI Technical Summary

Problems solved by technology

[0003] When testing the suction performance of automotive air-conditioning compressors, traditional equipment is connected to the shaft end of the compressor main shaft through a snap-in keyway structure. When pumping, the transmission shaft of the suction performance testing equipment for automotive air-conditioning The bayonet and keyway drive the compressor shaft to rotate at a high speed at an irregular speed. After the suction performance test is completed, the keyway at the shaft end of the compressor shaft will be worn and damaged, which will increase the reject rate of compressor products. In addition, the suction will be accelerated. Damage to performance testing equipment components increases the frequency of replacement of vulnerable parts of testing equipment, which is not conducive to the high-efficiency operation of the compressor production line
