Description

Technical Field

[0001] This utility model belongs to the field of plunger processing technology, and in particular relates to a grinding device for plunger processing. Background Technology

[0002] A plunger is a key component in hydraulic, pneumatic, or mechanical systems used to transmit pressure, achieve reciprocating motion, or control fluid flow. It is typically a cylindrical or near-cylindrical part that can perform linear reciprocating motion within a cylindrical cavity.

[0003] During machining, plungers will have cutting marks, burrs, or microscopic unevenness on their surface. Plungers typically need to operate in high-pressure, high-speed, or high-precision environments, and surface quality directly affects their performance. To improve sealing and increase the wear resistance of the plunger surface, a grinding device is needed to grind the plunger surface. During grinding, to prevent the plunger from shaking and causing positional displacement, a clamp needs to be manually adjusted to hold and fix the plunger. The manual adjustment process takes a long time, and multiple adjustments are required when grinding different positions of the plunger, reducing processing efficiency. Utility Model Content
