Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0011] The cutting tool feeding method for bearing ring turning of the present invention is to divide the complete tool feeding stroke into at least two sections of strokes, and perform a tool retraction after each section of stroke to break off chips. Specifically, the digital controller is used to control the servo motor to drive the carriage to realize the feeding and retracting of the tool. As an example, the complete feed stroke is divided into two strokes, the first feed stroke and the second feed stroke are respectively 60-80% and 40-20% of the complete feed stroke.

[0012] At present, hydraulic lathes are selected for turning bearing rings because hydraulic lathes have good rigidity and high turning force. However, since the hydraulic lathe adopts the feed control mode of hydraulic actuators, it is difficult to realize multiple movements of...

Abstract

The invention discloses a bearing ring turning and cutting feed method, which belongs to the technology of turning processing. According to the existing cutting feed control method, a cutter is easy to break, materials are easy to block, and the deviation from circular form is large, while the bearing ring turning and cutting feed method is characterized in that a complete cutting feed process is divided into at least two sections of processes, and primary retracting is carried out so as to break cuttings after each process is finished. Particularly, a digitizing controller is used for controlling a servo motor to drive a carriage to realize cutting feed and retracting; a pneumatic actuating element is adopted for realizing feeding, blanking, clamping of a workpiece, fast moving of the carriage. According to the bearing ring turning and cutting feed method, through at least two times of cutting feed and retracting to break the cuttings, the problem of curling of the cuttings is solved; inner stress generated by power cutting is released, so that deformation of the workpiece caused by the inner stress is reduced; and due to the adoption of digitization programmed control technology, a segmented feeding mode in a bearing ring turning processing process is realized, the inner stress caused by large cutting volume is eliminated, and the dimensional accuracy and the shape precision of bearing ring turning processing are improved.

Description

technical field [0001] The invention belongs to the turning processing technology, in particular to a turning tool feeding method for a bearing ring. Background technique [0002] During the processing of bearing rings, structures such as turning grooves, chamfers, and sealing grooves are required. Existing bearing ring turning processing equipment mostly adopts hydraulic drive, and there are fluctuations in cutting parameters set by the equipment due to changes in oil temperature during use. At the same time, due to the difficulty in adjusting cutting parameters during hydraulic drive, only one feed can be realized. , the internal stress is large, which affects the processing accuracy and shape accuracy of the product: ①In the process of turning and processing products in the bearing ring automatic turning production line, the setting of various parameters of the carriage feed, such as rotation speed, feed speed, and tool retraction The delay time will directly affect the ...
