Description

Technical Field

[0001] The invention relates to a fully automatic piston sliding shoe clearance detection tool for new energy vehicles. Background Art

[0002] Piston sliding shoe clearance detection is one of the most important detection processes in new energy vehicle air conditioning compressors. The accuracy of its measurement directly affects the service life and performance of the compressor.

[0003] The patent with the announcement number CN216482712U discloses a sliding shoe clearance detection tool for automobile air-conditioning compressor, which is composed of a base, a compressor positioning device and a measuring device, and the compressor positioning device and the measuring device are fixed on the base; the relative distance between the compressor positioning device and the measuring device is adjusted according to different compressor products, and the main structure of the existing sliding shoe clearance detection tool is roughly similar to it;

[0004] When using a similar inspection tool as described above, the operator is generally required to visually check the dial gauge reading or use a displacement sensor to verify the piston-shoe clearance value, and the operator is required to manually place the spindle and piston-shoe assembly into the corresponding slot. Because the number of measurements is very large, the worker becomes tired. Once the spindle and piston-shoe assembly are not properly placed, the inspection accuracy will be out of control, which will lead to a decline in the quality of the automobile air-conditioning compressor. When it is discovered later, mass production has often been completed, resulting in a large amount of rework;

[0005] The above problems can be overcome by using a robotic arm to replace manual loading and unloading and using a computer to calculate statistical detection data. However, due to the position design of the main shaft and piston sliding shoe assembly placement grooves, as well as the structure and coordination of the two, the action design of the robotic arm is demanding and complex. Even if the designed robotic arm can barely complete the loading and unloading actions, there are still defects such as slow loading and unloading speeds and the inability to guarantee placement accuracy, which requires further improvement. Summary of the invention

[0010] When the clearance between the swash plate and the piston shoe assembly of the main shaft is detected, the lifting platform is raised for the first time until the top surface is flush with the top surface of the high platform, and then the equipment frame moves forward to insert the swash plate into the lower end of the guide groove, and the two mounting arms are extended to allow the clamping platform to push the swash plate to abut against the guide groove and be clamped, and then the lifting platform is raised for the second time, driving the swash plate to be clamped between the shoes of the piston shoe assembly.
