Description

Technical Field

[0001] The utility model relates to the field of piston processing, in particular to a positioning device for processing a main pump piston. Background Art

[0002] The main pump piston is a key component in the main pump. It undertakes the important task of converting mechanical energy into hydraulic energy. During the operation of the pump, the piston compresses and discharges the liquid through reciprocating motion, thereby realizing liquid delivery or pressure conversion. Therefore, the processing quality and precision of the piston have a vital impact on the overall performance and efficiency of the main pump.

[0003] At present, pistons are mainly cast by molding. In order to ensure the quality of the pistons, they also need to be polished and deburred to make the piston surface smoother. During positioning polishing, some pistons need to be adjusted within a certain angle, which requires employees to manually change and adjust the direction. The debris after polishing needs to be manually cleaned, resulting in a decrease in efficiency. Therefore, we propose a positioning device for main pump piston processing to solve the above problems.
