Description
Technical Field
The invention relates to a bearing bush machining system and process, in particular to an improved bearing bush manufacturing process based on an automatic inner hole machining method.
Background
The bearing bush (bearing shell) is a part of a sliding bearing contacted with a shaft neck, is in a tile-shaped semi-cylindrical surface, is very smooth, is generally made of wear-resistant materials such as bronze, antifriction alloy and the like, and can be made of wood, engineering plastics or rubber under special conditions.
Thick-walled bearing shells may be cast and to improve friction properties, a layer of bearing alloy (known as a bearing lining) may be cast onto the inner surface of the bearing shell. In order to make the bearing alloy and the bearing bush adhere well, tenons, grooves or threads are often made on the inner surface of the bearing bush in various forms. The thin-wall bearing bush can be produced in large quantities by the processes of continuous rolling of bimetallic plates and the like.
Powder metallurgy is a method in which a basic material such as iron or copper powder is mixed with graphite, and the mixture is pressed and sintered to be formed. The pores can store lubricating oil, and the bearing is called as an oil-retaining bearing.
The bearing bush material is usually soft, the inner cylindrical surface is not suitable for being processed by a grinding method, and the bearing bush material can be processed by boring, diamond boring, scraping or grinding. The grinding should not be done by the method of matching the shaft diameter, but should be done by a special grinding rod with the same size as the hole size of the bearing bush. The scraping is mainly used for partial tile bearings and is carried out by a wide-edge scraper. When scraping by hand, the scratch should be shallow. The bearing bush with the complicated inner surface shape adopts a special boring method according to the specific shape.
In the bearing bush machining industry, with the improvement of automation degree, different devices such as a boring machine and chamfering devices are often connected through a conveying belt so as to improve production efficiency. In fact, the prior art has been able to adapt the front and rear machines to integrated transport. However, in the machining process, the bearing bush faces leftwards after the front machine such as a boring machine is machined, and when the bearing bush enters a rear machine such as chamfering equipment, the machining requirement is that the bearing bush enters the equipment in a state of facing rightwards, the turning process can be finished only manually at present, and because the production capacity of the bearing bush is large, the process greatly increases the labor capacity and reduces the production efficiency. CN201320804939.4 a conveying device for automatically steering bearing bushes provides a conveying device, but it cannot meet the requirement of automation.
In the course of working at present axle bush oil groove, the processing of axle bush oil groove all adopts the lathe, and is inefficient, and every shift does not exceed 1700, and intensity of labour is big, and manual clamping, hand cranking gilding plate feed still produce easily and collapse sword line or have edges and corners, can not guarantee the required precision. Although the CN201020289599.2 milling bearing bush oil groove device provides a processing scheme, the device cannot meet the processing modes of various oil grooves, and has poor universality and high cost.
When the punch head punches the positioning lip of the bearing bush in the prior art, the bearing bush is easy to damage, and the punch head is easy to break. CN201020289581.2 is a milling device before punching a bearing bush positioning lip, but the defect of low processing precision still exists.
Compared with the traditional process, the CN201811536596.1 high-precision unmanned control bearing bush machining method is greatly improved, but still has high machining cost and improved space, so that the efficiency and the precision are improved, the upgrading and the updating are realized, and the requirements of customers of different engines and diesel engines are met.
