Processing method for oil groove of inner wall of shaft sleeve

Abstract

The invention relates to a processing method for the oil groove of the inner wall of a shaft sleeve and the method comprises the follow steps of: 1) determining the depth and width of the oil groove, and arranging a fixture and a positioning device respectively on the two ends of a lathe bed; 2) placing the shaft sleeve in the fixture, and locking tight to fix the shaft sleeve; 3) fixing a cutter in the positioning device, and sticking the cutter into the shaft sleeve and fixing; 4) starting a motor to spin the shaft sleeve, wherein the cutter is milling the inner wall of the shaft sleeve; and 5)stopping the motor, withdrawing the cutter and loosing the fixture. The method is advantageous by simple operation, accurate positioning in processing, and reduced time for repeated confirmation; therefore solving the problem caused by inaccurate processing position of the oil groove, greatly reducing processing cost and time, overcoming the disadvantages of low efficiency, high cost and long working hours, realizing relatively high processing quality and production efficiency, and satisfying the requirements of mass production.

Description

technical field [0001] The invention relates to a machining method, in particular to a machining method for an oil groove on the inner wall of a shaft sleeve. Background technique [0002] In the moving parts, the wear of the parts is caused by long-term friction. When the shaft and the hole are worn to a certain extent, the parts must be replaced. Therefore, it is necessary to choose a shaft sleeve with lower hardness and better wear resistance, which can reduce shaft and hole wear. For the wear of the seat, in order to better match the movement of the sleeve and the shaft, it is necessary to open an oil groove on the inner surface of the sleeve to achieve the purpose of lubricating and storing lubricating oil, so as to prevent the shaft from being aggravated or even damaged due to lack of oil. A processing method of the oil groove is to turn the inner surface of the workpiece by the screw rod to drive the forming tool. Although this method is simple, it has the following d...

Problems solved by technology

A processing method of the oil groove is to turn the inner surface of the workpiece by the screw rod to drive the forming tool. Although this method is simple, it has the following disadvantages: 1. It is difficult to control the stroke of the tool, and it is difficult to ensure that the oil groove is cut during processing. The depth and width of the workpiece are very easy to pull the oil tanker out of the end surface of the workpiece, resulting in waste and increasing costs; 2. Higher requirements for workers' manipulation skills; 3. Long processing time and low production efficiency make it difficult to meet high-efficiency and mass production requirements; oil tank Another processing method is to place the blank between the upper and lower oil groove molds before the blank is made into a shaft sleeve, and realize the forming of the upper oil groove of the blank under the drive of the hydraulic cylinder. This method is used to process large-sized shaft sleeves , for small-sized bushings, the billet will be damaged due to excessive pressure, wasting raw materials and increasing the cost
