AI Technical Summary
Technical Problem
In the existing technology, during the oil injection process of the damper, the remaining grease in the pipeline rushes into the sleeve when the oil injection is completed, which affects the accuracy of the oil injection volume.
Method used
An oil injection device was designed. By gradually reducing the inner diameter of the oil injection pipe and the stroke of the pumping piston, combined with a one-way valve structure, the amount of grease injected is controlled to ensure the accuracy of oil injection.
Benefits of technology
It reduces the amount of extra grease injected during the oiling process and improves the accuracy of the oiling operation.

Abstract
The utility model provides a kind of oil injection equipment for damper processing, belong to damper processing technical field, including perfusion assembly, oil injection pipe, conveying table and pumping piston. The perfusion assembly includes several oil injection tanks arranged along the conveying direction of conveying table, the bottom of the oil injection tank is equipped with oil injection pipe, the inner diameter of the oil injection pipe gradually decreases along the conveying direction of conveying table, the inside of the oil injection tank is equipped with pumping piston, the pumping piston reciprocates in the inside of the oil injection tank. The utility model gradually reduces the inner diameter of the pipe along the direction of conveying damper sleeve, and the stroke of the pumping piston inside the oil injection tank reciprocates up and down along the direction of decreasing pipe diameter, further reduces the additional grease injection caused by stopping oil injection during oil injection process, and increases the accuracy of oil injection operation.
