Device for finish turning of rimless end face and chamfer of flanging shaft sleeve

Abstract

The invention discloses a device for finish turning of a rimless end face and a chamfer of a flanging shaft sleeve. The device comprises a vertical plate (1), a pressing sliding block (2), a screw (3), a nut block (4) and a base (5). The vertical plate (1) is fixedly arranged on the upper face of the base and provided with an embedded hole, a sliding groove is arranged in the upper portion of the embedded hole, the pressing sliding block can slide in the sliding groove up and down, the lower end of the screw is connected with the upper face of the pressing sliding block, and the nut block is fixed on the upper face of the vertical plate and spirally connected with the screw. When the device is applied, a lathe chuck is provided with a cutting cutter head, the base is fixed on the upper face of a middle drag plate positioned on a lathe large drag plate, a workpiece is located in the embedded hole of the vertical plate to be fixed by the screw through the pressing sliding block, a rimless end is towards the cutting cutter head, a lathe is started, the large drag plate is dragged to move the workpiece to be close to the cutting cutter head, the processing of the rimless end is finished in one time, the technical scheme of lathe motor shutdown, dragging and workpiece reloading for continuous processing is not needed, and the goal of improvement of efficiency and quality, reduction of costs and working strength and easiness in clamping is achieved in the processing of the rimless end of the flanging shaft sleeve.

Description

technical field [0001] The invention relates to a lathe cutting processing device, in particular to a device for finishing the edgeless end face and chamfering of a flanged bushing by using a lathe to cut and process the borderless end face and chamfering of the flanged bushing. Background technique [0002] The bushing is a cylindrical bearing bush, and the bushing with a flange step at one end is called a flanged bushing, and the end with a flange is called a flanged end, and the end opposite to the flanged end is called a borderless bushing. end; in the production and manufacture of the flanging bushing, it is necessary to cut and flatten the two end faces of the bushing, and to cut and chamfer the inner and outer circumferential edges of the two end faces. Rotating on the chuck, the turning tool installed on the tool holder, under the drag of the large and medium carriages, performs flattening and chamfering processing on the flanging end face and inner and outer periphe...

AI Technical Summary

Problems solved by technology

[0002] The bushing is a cylindrical bearing bush, and the bushing with a flange step at one end is called a flanged bushing, and the end with a flange is called a flanged end, and the end opposite to the flanged end is called a borderless bushing. end; in the production and manufacture of the flanging bushing, it is necessary to cut and flatten the two end faces of the bushing, and to cut and chamfer the inner and outer circumferential edges of the two end faces. Rotating on the chuck, the turning tool installed on the tool holder, under the drag of the large and medium carriages, performs flattening and chamfering processing on the flanging end face and inner and outer peripheral edges of the flanging sleeve. Among them, the lathe workers process according to the following procedures: parking and clamping the workpiece, driving, feeding the end face of the tool, retracting the tool, chamfering the inner round edge of the tool, retracting the tool, feeding the outer round edge and chamfering of the tool, parking and taking The lower workpiece is turned around and clamped, the other end is cut and processed, and the above process is repeated. After the car is finished, the car is stopped to remove the semi-finished product, the workpiece is replaced, and the machine is started again for processing. This cycle is repeated, the work intensity is high, and the efficiency is low. The loading and unloading of the workpiece must be frequently opened and stopped. , the lathe motor consumes a lot of energy, resulting in high labor costs and high power consumption costs, and it is difficult to ensure the consistency of the chamfer width. In addition, it is difficult for the chuck of the lathe to clamp the flange end of the workpiece to cut and process the edgeless end, which is prone to turning tools. The accident of turning over the workpiece; therefore, the prior art has the problems and deficiencies of low efficiency, high cost, poor quality, high working intensity, and difficult clamping of the flange end of the workpiece
