Roller pin processing technology and grinding miller for technology

Abstract

The invention relates to the technical field of shaft part processing, in particular to a roller pin processing technology. The roller pin processing technology comprises the following steps that 1, steel wire uncoiling is conducted, specifically, a steel wire coil is coiled on an uncoiling frame for uncoiling; 2, steel wire straightening is conducted, specifically, the uncoiled steel wire is sentinto a steel wire straightening machine for straightening; 3, steel wire cutting is conducted, specifically, the steel wire is straightened and then cut to form a steel column; 4, steel column grinding is conducted, specifically, the steel column is put into the grinding miller for grinding and deburring; and 5, steel column polishing is conducted, specifically, the grinded steel column is put into a centerless polishing machine for polishing. According to the roller pin processing technology, the steel column can be subjected to burr cleaning before being polished by the centerless polishingmachine, and thus the effect that the probability of the burr stabbing assembly personnel during the subsequent installation is reduced is achieved.

Description

technical field [0001] The invention relates to the technical field of processing shaft parts, in particular to a needle rolling processing technology. Background technique [0002] The cross shaft is also called the ten-byte, that is, the universal joint. It is a machine that realizes variable-angle power transmission. It is used for the position where the direction of the transmission axis needs to be changed. In order to make the cross shaft rotate smoothly, needle rollers need to be installed on the cross shaft. . [0003] The existing needle roller processing technology includes the following steps: [0004] Step 1: Uncoiling the steel wire, winding the steel wire on the uncoiling stand for uncoiling; [0005] Step 2: Straightening the steel wire, sending the uncoiled steel wire into the steel wire straightening machine for straightening; [0006] Step 3: Cutting the steel wire, straightening the steel wire and then cutting to form a steel column; [0007] Step 4: G...

AI Technical Summary

Problems solved by technology

[0008] The above-mentioned existing technical solutions have the following defects: the existing needle-rolling processing technology has a relatively rough cutting surface after cutting, and there will be burrs at the same time, and when the centerless grinder is used for subsequent grinding, only the circumferential direction of the steel column is polished, and the length of the steel column The two ends of the direction cannot be polished and the burrs are not easy to remove, and the burrs are easy to stab the assembler during subsequent installation
