Bearing-crankshaft intelligent press mounting method and system for scroll air-conditioning compressor

Abstract

The invention relates to a bearing-crankshaft intelligent press mounting method and a bearing-crankshaft intelligent press mounting system for a scroll air-conditioning compressor. The system comprises three parts, namely a press mounting device, an industrial robot and a visual device, wherein the industrial robot receives position signals of a bearing and a crankshaft output by the visual device, processes the position signals of the bearing and the crankshaft to generate a motion trail of the industrial robot, grabs the bearing to put the bearing into the press mounting device and grabs the crankshaft to put the crankshaft into the bearing; the press mounting device receives a state signal of the industrial robot, converts the state signal into a control signal and controls the press mounting device to perform press mounting on the crankshaft into the bearing; and after receiving the state signal of the press mounting device, the industrial robot takes the bearing and the crankshaft subjected to press mounting out of the press mounting device.

Description

technical field [0001] The invention relates to a bearing-crank shaft intelligent press-fitting system and a press-fitting method of a scroll air-conditioning compressor. Background technique [0002] Due to its low power consumption and good high-speed performance, the scroll air-conditioning compressor is gradually replacing the swash-plate compressor as an important equipment in the refrigeration process of vehicle air-conditioning. In the scroll air conditioner compressor, the bearing and the crankshaft are the two key components. The tightness of these two components directly affects the performance of the scroll compressor to compress air, affects the cooling effect, and affects the service life of the compressor. [0003] There is an existing method for press-fitting bearings on crankshafts, for example, Chinese invention patent CN100999047A, which includes first fixing the crankshaft on the bracket; The axis line coincides with the axis line of the crankshaft, and ...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem that the bearing and crankshaft press-fitting automation of air-conditioning scroll compressors is not high, relying on manual assembly has low precision and slow speed, which affects product quality and assembly efficiency, resulting in reduced service life of the compressor. The purpose is to provide an intelligent press-fitting method and press-fitting system applied to scroll air-conditioning compressor bearings and crankshafts, which can intelligently judge the state of bearings and crankshafts, and automatically press-fit the crankshafts to the in bearing
