The sliding plate is slidably connected to the machine tool, the sliding drive assembly is arranged on the machine tool, the movable plate is slidably connected to the sliding plate, the movable plate is fixedly connected to a clamping plate, the opposing assembly is arranged on the sliding plate, the rotating assembly is arranged on the clamping plate, the grinder is arranged on the machine tool through a lifting assembly, the water spray gun is fixedly connected to the machine tool through a support frame, the water tank is fixedly connected to the machine tool, the water tank is connected to a water pump through a connecting pipe, the water pump is fixedly installed on the machine tool, and an upper water pipe is connected between the water pump and the water spray gun.

[0004] However, the above device has the following technical problems when actually used:

[0005] 1. The above device clamps the connecting rod by rotating disks on both sides, but Figure 3 It can be seen that there is a stop edge on the side of the rotating disk. The stop edge will partially block the two ends of the connecting rod. Therefore, during the actual grinding process, the grinder cannot easily grind to the end position of the connecting rod due to the influence of the stop edge, which causes limitations in the actual use of the above-mentioned device.

[0006] Second, when the above-mentioned device is used to grind the connecting rod, if the size of the connecting rod does not match the rotating disk, then after actual assembly, the connecting rod may be offset due to the top pressure of the grinder, resulting in eccentric rotation under the clamping action of the rotating disks on both sides, thereby affecting the subsequent grinding of the connecting rod surface by the grinder. Utility Model Content

At the same time, when the connecting rod and the rotating disk in the above device do not match in size, in the subsequent grinding, the connecting rod may be subjected to the top pressure from the grinder, and the position of the connecting rod may be offset, thereby causing eccentric rotation under the clamping action of the rotating disks on both sides, affecting the actual grinding effect of the subsequent grinder.
