Usually, when producing the air conditioning pipeline, the pressure plate joint will be directly prefabricated on the air conditioning pipeline. Then, a through hole is prefabricated on the pressure plate joint for easy fixing, and the air conditioning pipeline is fixed to the air conditioning mounting seat through bolts.

[0003] The quantity of each batch of automobile air conditioning pipe pressure plates is very large (usually starting from several thousand pieces). The micrometer is used to measure the sealing groove of the pressure plate. This method has high requirements for the inspector. Once the micrometer is tilted, the measurement result will be biased. According to the sampling ratio, several thousand pressure plates need to be measured for hundreds of pieces, and the micrometer needs to be reused hundreds of times. The manual measurement efficiency of the inspector is extremely low and it is easy to produce measurement errors, resulting in losses to production. The sealing groove is where the sealing ring is installed. Once the size deviates, it will affect the use of the sealing ring, thereby causing gas leakage. Utility Model Content
