[0026] The implementation principle of the compressor housing clamping mechanism in this application embodiment is as follows: During operation, the compressor housing is sleeved on the outside of the four support rods 2 through the central hole. Then, the push cylinder 61 is used to push the fixed plate 62 and the positioning rod 63 to move. The four positioning rods 63 push the compressor housing to move. Since the overall shape of the compressor housing is circular, the compressor housing can be initially positioned. Then, the lifting cylinder 31 is used to push the push block 32 upward. At this time, the connecting rod 35 rotates clockwise downward. Under the guiding and limiting action of the guide rod 37 and the fixed block 38, the compressor housing is initially positioned. The connecting rod 35 can drive the support rod 2 to move outward along the length of the guide rod 37, so that the support rod 2 fixes the compressor housing by pressing the inner wall of the central hole of the compressor housing. Then, the adjusting motor 55 drives the bidirectional threaded rod 52 to rotate, driving the two nut seats 53 to move closer or further away from each other to adjust the two pressing heads 411 to a suitable position, ensuring that the pressing heads 411 are fully pressed down on the surface of the compressor housing. Then, the pressing cylinder 41 is used to push the pressing heads 411 to press down and fix the compressor housing, thus stabilizing the compressor housing.
