[0057] The longitudinal servo slide 31 , the transverse servo slide 34 and the lifting cylinder 33 cooperate with each other to enable the polishing motor 36 to move arbitrarily in the longitudinal, transverse and vertical directions.

[0058] In the utility model, when in use, by controlling the piston rod of the lifting cylinder 23 to extend or retract, the connecting rod 25 can be used to drive the slider 26 to move along the slide rod 27 to clamp the regular water pump housing, and by controlling the piston rod of the clamping cylinder 28 to extend or retract, one or several clamping blocks 29 can be driven to approach or move away from the center of the limit plate 22 to clamp the irregular water pump housing. The longitudinal servo slide 31, the transverse servo slide 34 and the lifting cylinder 33 cooperate with each other to drive the polishing motor 36 to move, so that the polishing wheel 37 contacts the water pump housing, and the polishing motor 36 drives the polishing wheel 37 to rotate to polish the water pump housing.

[0066] The lifting motor 43 is a servo motor. After the lifting motor 43 is started, the output shaft of the lifting motor 43 can drive the lifting screw 44 to rotate. Since the lifting screw 44 is threadedly connected to the carrier plate 46 and both sides of the carrier plate 46 are slidably connected to the lifting slide rod 45, the lifting screw 44 rotates and drives the carrier plate 46 to move along the axis direction of the lifting screw 44, thereby driving the water pump housing to rise or fall, so as to realize automatic loading and unloading of the water pump housing.

[0067] When loading or unloading materials, it is necessary to rotate the motor 14 to drive the rotating frame 13 to rotate until the clamping device 2 faces the ground and the rotating frame 13 remains parallel to the ground.
