Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts detection equipment, in particular to a dynamic balance detection loading device for a compressor rotor. Background Art

[0002] The compressor rotor is a key component of an automotive compressor. Its accuracy and performance are crucial to the efficient operation of the vehicle's air conditioning system. Among the many performance indicators of the compressor rotor, dynamic balancing is particularly critical, as it directly affects the smooth operation and reliability of the compressor.

[0003] However, there are many deficiencies in the existing technology for dynamic balancing performance testing of compressor rotors. First, due to the structural characteristics of the camshaft, its testing process requires the design of a complex fixture structure. This complex design not only makes the clamping and disassembly process cumbersome, but also easily causes stress damage to the camshaft during the clamping process, thereby affecting the accuracy and reliability of the test results. Secondly, the existing detection method requires the use of different equipment to perform axial and radial performance tests on the compressor rotor respectively. This separate detection method cannot simultaneously verify the various performance of the compressor rotor in the same process, resulting in a cumbersome detection process and failure to fully meet the actual application requirements in actual service scenarios. In addition, the existing detection technology cannot detect the compressor rotor in a temperature-controlled environment, and the temperature-controlled environment is an important factor in simulating real service conditions. The existing detection method has great limitations in actual applications.
