Novel technology for turning bearing outer ring connecting line

Abstract

The invention provides a novel technology for turning a bearing outer ring connecting line. Three single machines are adopted for connecting line machining, and the technology comprises the following steps that 1, the first single machine is adopted for finish turning of the inner diameter and a chamfer of one side of an outer ring or cutting of a sealing groove or cutting of an outer chamfer; 2, the second single machine is adopted for finish turning of the inner diameter and a chamfer of the other side of the outer ring or cutting of the sealing groove or cutting of the outer chamfer and pre-turning of a part of a locking groove; and 3, the third single machine is adopted for finish turning of an outer ring roller path and cutting of the outer ring roller path and the locking groove. Compared with existing four-machine connecting line machining technology, the novel technology has the beneficial effects that one machine tool is directly omitted, and the cost of a production line is greatly lowered; meanwhile, the machining time is saved, and the machining efficiency of the production line is greatly improved; and the novel technology is the innovative connecting line machining mode.

Description

technical field [0001] The invention is suitable for the turning technology field of the hydraulic program-controlled connection of the bearing outer ring, and particularly relates to a new technology for the connection turning of the bearing outer ring. Background technique [0002] Hydraulic program-controlled in-line turning of bearing outer ring is a very common turning method at present. Through the combination of a single hydraulic program-controlled machine tool, and the cooperation of special fixtures and forming tools, the turning of a ferrule is completed. [0003] The program-controlled hydraulic automatic lathe is an automatic lathe controlled by a PLC program that uses a hydraulic system for automatic cutting processing. Usually, there are two left and right pallets, which respectively adjust the inner diameter, chamfering, raceway, sealing groove, stopper, etc. of the bearing ring. The moving grooves and other parts are cut. The stroke in both directions of ea...

AI Technical Summary

Problems solved by technology

The small square in the figure is the positioning surface, the triangular block is the clamping surface, and the direction of the arrow is the direction in which the tool enters the cutting. Through these four steps, the turning process of the entire bearing outer ring is completed, but it requires 4 single machines for in-line processing, and the cost is relatively high. , long processing time
