An automatic measuring mechanism for ab value of scroll compressor

Abstract

The invention relates to the technical field of production of vehicle air-conditioning compressors, in particular to an automatic measuring mechanism for the AB value of a scroll compressor. It includes the measuring mechanism lifting device and the A value measuring mechanism and B value measuring mechanism arranged on the measuring mechanism lifting device, wherein the A value measuring mechanism presses the front cover end face of the moving plate assembly and the moving plate end face, and the front cover end face is used as the A value Measuring benchmark, measure the distance A value between the end face of the front cover and the end face of the moving plate through the A value displacement sensor; The end face is used as the B value measurement benchmark, and the distance B value between the upper end face of the cylinder block and the end face of the static disk wear plate is measured by the B value displacement sensor. The invention has high measurement precision, can improve operation efficiency, effectively guarantee product quality, and can realize compatible production of different types of products through quick replacement of a small amount of tooling.

Description

technical field [0001] The invention relates to the technical field of production of vehicle air-conditioning compressors, in particular to an automatic measuring mechanism for the AB value of a scroll compressor. Background technique [0002] The scroll compressor is composed of two double-function equation-shaped moving and static scrolls meshing with each other. In the working process of suction, compression and exhaust, the angular relationship between the dynamic and static disks and the control of the axial end face clearance are very important, and they are the key processes that determine the refrigeration performance of the scroll compressor. In the automatic production of scroll compressors, the control of the axial end face clearance between the dynamic and static discs requires the measurement mechanism to have high detection accuracy and stability, so that the adjustment gasket with the appropriate gear can be selected. Since the current measurement mechanism d...

AI Technical Summary

Problems solved by technology

Since the current measurement mechanism does not have an ideal floating structure, etc., it is not stable enough in the actual automatic production of large-scale products, and the accuracy is low. Sometimes it is even necessary to manually install an adjusting gasket of a certain thickness through part batches and experience. After multiple assembly processes, until the whole machine fails to pass the performance test, a large number of rework is required, gaskets are replaced and the assembly process is repeated, resulting in a huge waste of time and cost, and low production efficiency
