Due to the meshing relationship between the inner end of the active internal gear disc 502 and the bottom end surface of the transmission gear 503, the transmission gear 503 can be driven to rotate. And due to the meshing relationship between the top end surface of the transmission gear 503 and one side of the sliding seat 403, multiple sliding seats 403 and the sliding seat 403 can be driven to move simultaneously along the inside of the sliding cavity 402, and the semi-finished pump body interfaces with different inner diameters can be clamped by shrinking and expanding.

[0073] Then, the lifting component 201 can be activated to drive the moving component 202 and the grinding component 203 to move up and down as a whole. Then, the moving component 202 is activated to drive the grinding component 203 to move telescopically. At the same time, the grinding component 203 is activated to grind the surface of the semi-finished pump body. Then, when it is necessary to switch the grinding position and direction, the transmission disc 601 can be activated to drive the power motor 602 to rotate, so as to drive the threaded rod 603 to slide inside the movable cavity 7, and drive the movable block 604 to drive the transmission arm 605 and the fixture support table 3 as a whole to rotate, finally meeting the grinding treatment in different position directions.
