Variable displacement compressor main shaft displacement detection device

A variable displacement compressor main shaft displacement detection device comprises a rack, and an operation panel, an electric box, a tool bottom plate, a lifting device, a detection device and a pressing device are arranged on the rack. The tool has the advantages that the characteristic that the variable displacement compressor is provided with the elastic gasket is utilized, after the compressor is placed on the tool bottom plate, the lifting device is used for positioning the compressor, and then the compressing device is used for compressing the elastic gasket inside the compressor; and the detection device determines the spindle displacement of the variable displacement compressor according to the measured position height variation before and after compression, and compares the spindle displacement with a set spindle displacement range to determine whether the spindle displacement is qualified or not. The whole detection process is good in cooperativity and high in detection efficiency. 一种变排量压缩机主轴窜动量
