High-precision oil line machining method for bearing bush and assembling method

Abstract

The invention relates to a high-precision oil line machining method for a bearing bush and an assembling method. High-precision oil line machining equipment for the bearing bush comprises a pairing turning machine and a machining part; the pairing turning machine is used for distributing chamfered bearing bush parts into to-be-machined boring marking bearing bush parts; and the machining part is used for carrying out boring marking and oil groove machining on the boring marking bearing bush parts and comprises a boring marking center, a boring clamp machine, an oil groove machining center a groove milling clamp machine and a bearing bush output belt, the boring marking center is used for carrying out boring marking on the to-be-machined boring marking bearing bush parts, and the boring clamp machine is connected with the bearing pairing turning machine in a working procedure and feeds materials to the boring marking center, the oil groove machining center is used for machining the bored marked bearing bush parts into machined bearing bush parts, the groove milling clamp machine is in process connection with the boring clamp machine and feeds the materials to the oil groove machining center, and the bearing bush output belt is used for outputting the machined bearing bush pats output by the groove milling clamp machine. The equipment is reasonable in design, compact in structureand convenient to use.

Description

technical field [0001] The invention relates to a processing method and an assembly method for high-precision oil wires of bearing bushes; the parent case is CN201811537434.X High-precision oil wire processing equipment for bearing bushes, a processing method and an assembly method. Application date: 20181215. 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...

AI Technical Summary

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 processed into the required shape with a tool, the bearing bush is removed, and the inner surface of the bearing bush is manually polished with sandpaper until it meets the requirements. Not only the labor cost is high, but the grinding may be uneven. The efficiency is still very low and needs to be improved urgently
