Problems solved by technology

[0005] However, since the machining of the bearing pad by the tool is relatively rough, in order to make the inner surface of the bearing pad smooth, it is necessary to use sandpaper and other materials for grinding
At present, the grinding is done manually, that is, after the inner surface of the bearing bush is pr

Abstract

The invention discloses a high-accuracy bearing bush inner side machining device. According to the high-accuracy bearing bush inner side machining device, a grinding wheel is installed at a position, close to a tool, of a rotary shaft, primary rough machining is carried out on the inner side of a bearing bush by means of the tool to enable the inner surface of the bearing bush to be machined into a needed shape when the rotary shaft rotates, and along with the movement of the rotary shaft in the axial direction of the bearing bush, secondary fine machining is carried out on the inner side of the bearing bush by the grinding wheel to enable the inner surface of the bearing bush to be smooth and meet requirements. Therefore, two machining procedures are achieved through one-time machining, working efficiency is improved, and labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bearing bush processing, in particular to a precision machining device for the inner surface of a bearing bush. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. The bearing pad is the part of the sliding bearing that is in direct contact with the shaft. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloy. It is shaped like a tile-shaped semi-cylindrical surface. The function of the bearing bush is to bear the f...
