Description

Technical Field

[0001] The present application relates to the technical field of grinding devices, and in particular to a grinding device for producing a main pump piston rod. Background Art

[0002] Grinding refers to a processing method that uses abrasives and grinding tools to remove excess material from a workpiece. Depending on the process purpose and requirements, there are many forms of grinding process methods. In order to adapt to development needs, grinding technology is developing towards precision, low roughness, high efficiency, high speed and automatic grinding.

[0003] The piston rod needs to be ground on its surface during processing. The existing piston rod production grinding device is difficult to position the axis of the piston rod during use, and the clamping device will affect the grinding and cannot be processed in one go, which reduces the processing efficiency and is not conducive to use.

[0004] For example, the patent with publication number CN114714203B specifically discloses an automatic grinding processing equipment for piston rod production, including a base, a first clamping assembly, a second clamping assembly, a first telescopic member and a clamping member. Thus, the piston rod axis is accurately positioned and can be applied to piston rods of different lengths, ensuring the stability of the piston rod rotation and avoiding the influence of the clamping device on the grinding of the piston rod.

[0005] When the above patent bending device is in use, the piston rod is clamped and positioned by the clamping assembly, and the piston rod is ground by the grinding assembly, and the collecting assembly is arranged on the grinding assembly and moves with the grinding assembly to collect the grinding shavings generated during grinding. However, during the grinding process, when the piston rod is ground by the grinding assembly, the surface temperature of the piston rod is likely to be high, and the grinding shavings adhere to the surface of the piston rod, thereby affecting the grinding accuracy of the piston rod. At the same time, the collecting assembly arranged only on the grinding assembly and at the lower end of the piston rod cannot completely collect the grinding shavings, and the grinding shavings are easy to scatter. Therefore, it is necessary to design a grinding processing device for the production of the main pump piston rod to solve the above problems.
