In this way, multiple grinding wheels can be fixed at the same time by setting multiple clamping plates, which is convenient for subsequent processing of the grinding wheels.

[0018] 2. In the utility model, through the setting of the lifting unit, when the grinding wheel needs to be clamped, the grinding wheel can be sleeved on the sleeve column to initially limit the position of the grinding wheel, and then the second cylinder is started to drive the second telescopic column to extend, thereby driving the lifting plate and the grinding wheel on the sleeve column to rise, and then the first cylinder is started so that the edge of the grinding wheel is in the arc groove, and then the second cylinder is started to drive the lifting plate and the sleeve column to descend, so that multiple grinding wheels are lifted and fixed in turn, ensuring that the vertical positions of multiple grinding wheels are the same, avoiding damage to some grinding wheels due to errors in the position of the grinding wheels during subsequent processing, and improving the convenience of the clamp.
