Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device for an impeller casting which is convenient for fixing and belongs to the technical field of impeller casting processing. Background Art

[0002] The impeller of a water pump is generally cast, and there are many burrs on the impeller after casting. The impeller grinding device of a water pump is an auxiliary device used to grind the burrs during the production process of the water pump. The grinding device makes the blades on the impeller smooth, thereby improving the water conduction performance of the impeller.

[0003] However, during the grinding process of the existing water pump impeller, the impeller is generally placed directly on the grinding table. When the grinding head of the grinder contacts the impeller surface, the impeller without limiting is prone to displacement or shaking, thereby causing the grinding position to shift, which is not conducive to improving the grinding effect of the impeller.

[0009] Preferably, the card slot is arranged in a T-shaped structure, and the mounting seat is located at the central part of the top end of the turntable.

[0010] Preferably, the mounting mechanism includes a clamping block and a sliding plate. The sliding plate is slidably mounted at the card slot part. The top end of the sliding plate is fixedly connected with a clamping block, and the top end of the clamping block is fixedly connected with a pulling block and a pressing plate.

[0011] Preferably, several pressing plates are arranged at equal intervals in a ring shape, and the pressing plates are arranged in an arc surface structure and are in contact with the side wall of the mounting seat.

Then, the control switch of the hydraulic rod fixed in the mounting seat is started.
