High-precision plunger forming process

Abstract

The invention provides a high-precision plunger forming process. The high-precision plunger forming process comprises the following steps that 1, plungers are manually loaded; 2, the tail ends of the plungers are slotted, a clamping part moves to a second driving assembly, a clamping assembly is matched with a positioning shaft to clamp the plungers, a slotting mechanism carries out slotting work on the plungers, and after slotting work of all the plungers is completed, a first driving assembly drives a rotary disc to continue to rotate to drive the plungers to be switched to a ball milling station; 3, the head ends of the plungers are ball-milled; 4, the plungers are automatically discharged; and 5, the plungers are automatically fed. The problems that when the plungers are machined again, the plungers are manually loaded to a machining lathe, and after machining is completed, the plungers are manually taken down and stored, so that the manual labor force is consumed, and meanwhile the plunger machining efficiency is very low are solved.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a high-precision forming process for plungers. Background technique [0002] During the working process of the swash plate axial piston pump and motor, the plunger has two motion modes: axial movement and rotation around the central axis. For swash plate axial piston pumps and piston motors, the plunger body is a cylindrical structure, and the movement in the cylinder includes two types of movement, horizontal movement and self-rotation. The plunger is affected by the pressure of the hydraulic oil. When the plunger moves horizontally in the cylinder, it will form a certain angle with the horizontal direction, which will cause mechanical contact between the two ends of the plunger and the outer wall of the cylinder, resulting in wear; When the plug rotates around the drive shaft, the plunger itself will rotate, and the rotation of the plunger will aggravate the wear of the ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a plunger high-precision molding process for the deficiencies of the prior art. By sequentially completing the upper loading work, slotting work, ball milling work and blanking work of the plunger on one device, the entire process can be realized. The continuous tightness of the work, the whole work can realize unmanned operation, and the degree of automation is high, which solves the problem that the plunger in the prior art is manually uploaded to the processing lathe when the plunger is processed, and the processing is completed Finally, it is manually removed and stored, so while consuming manual labor, the efficiency of plunger processing is very low.
