The gear ring 53 and the rotating seat 51 are driven to rotate through the gear 54.

[0035] When the output end of the cylinder six 52 controls the moving block 55 to move downward, the grinding tool 501 rotates with the swing arm 56 and fits against the end of the water pump housing 6 sleeve, and grinds the inner side of the sleeve end, and processes the chamfer at the sleeve end of the water pump housing 6.

The cutting operation process is uniform, which speeds up the processing efficiency of the water pump housing 6, and the hole groove ends on the water pump housing 6 are efficiently processed, which is suitable for the forming processing of the water pump casting housing.

[0036] Here’s how it works: For the water pump housing 6 produced by batch casting, it is loaded into the conveying path 11 in sequence, and the water pump housing 6 is pushed to move horizontally so as to be conveyed to the bottom of the positioning assembly 2.

[0037] Moreover, the rotation of the shaft 22 can drive the levers 27 on both sides to slide in the vertical grooves 26, so that the two moving rods 24 move in opposite directions, and then the limiting rollers 29 fit into the water pump housing 6, completely locking the water pump housing 6.

[0038] Finally, the output end of the cylinder 4 31 controls the pressure rod 33 to move downward to press the pressure rod 33 against the water pump housing 6 to ensure that the shaft sleeve axis of the water pump housing 6 is coaxial with the output shaft of the motor 2 36. During the downward movement of the pressure rod 33, when the bottom end of the moving rod 2 401 contacts the end of the shaft sleeve of the water pump housing 6, the position of the moving rod 2 401 is supported and fixed by the end of the shaft sleeve of the water pump housing 6. As the rotating plate 41 continues to move downward, the moving seat 46 moves downward, and the driven rod 49 rotates around the end portion rotatably connected to the moving rod 401 as the axis, pulling the two moving seats 46 closer together, and the spring 404 is in a compressed state, so that the two grinding wheels 48 fit the inner and outer sides of the shaft sleeve of the water pump housing 6, and the top end of the moving rod 401 is slidably connected to the guide ring groove 35 to prevent the moving rod 401 from vibrating.

[0039] Then move the side frame 5 to the top of the water pump housing 6, and then the cylinder 6 52 pushes the swing arm 56 to rotate until the grinding tool 501 is attached to the shaft sleeve of the water pump housing 6, rotate the rotating seat 51, and finally use the grinding tool 501 to process the water pump housing 6.
