A synchronizer gear sleeve deburring machine and its use method

Abstract

The invention relates to a deburring machine for a synchronizer gear sleeve and a method for using the same. It comprises a machine tool body capable of fixing a ring-shaped synchronizer gear sleeve workpiece. The push knife moves to remove the burr of the inner spline of the workpiece and moves downward to return to its original position. The push knife includes an outer spline that cooperates with the inner spline of the workpiece; the lower end of the workpiece is coaxially sleeved on the upper end of the push knife with a gap between them There are gaps. In the present invention, the workpiece is fixed on the machine tool body, the push knife is socketed on the lower side of the workpiece, and the external splines are arranged to cooperate with the internal splines of the workpiece, and the deburring method of pressing up and down is adopted to effectively remove all burrs; only Through the upward movement of the push knife, the burr is removed at one time, and the efficiency is extremely high. There is a gap between the outer spline of the push knife and the inner spline of the workpiece, so that the push knife will not damage the surface of the inner spline of the workpiece and will not affect the roughness of the tooth surface. The degree of deburring will not be missed; at the same time, the transfer of parts is reduced and the bumping of parts is prevented.

Description

technical field [0001] The invention belongs to the field of synchronizer processing, and in particular relates to a synchronizer gear sleeve deburring machine and a use method thereof. Background technique [0002] At present, the splines of the existing synchronizer gear sleeves are processed with connected teeth, missing teeth, V-shaped grooves and other small teeth. In China, forming milling cutters are used to process 90° V-shaped grooves on the original internal splines. and 25° chute, etc., resulting in serious burr flanging, see Figure 2 to Figure 4 , the spline of the synchronizer gear sleeve is the internal spline of the workpiece 2, including three evenly distributed teeth 12 along the circumferential direction of the workpiece 2, three groups of missing teeth 13 (with 25° inclined grooves), three V-shaped grooves 14 and Several small teeth, the burr is located on the tooth surface of the connecting tooth 12, the missing tooth 13, the V-shaped groove 14 and the s...

AI Technical Summary

Problems solved by technology

Among them, the burrs on the tooth-missing surface and the spline tooth surface near the V-shaped groove are mainly removed by manual filing. Internal spline teeth are removed tooth by tooth in the direction of the internal spline, which is inefficient and easy to scratch the tooth surface of the internal spline, affecting the roughness of the tooth surface, and repeated manual handling will cause parts to bump; manual processing has a faster cycle time of 40 seconds / piece

[0003] To solve the problem of burrs, Germany has equipped an automatic deburring mechanism in the existing special machine tools for compound processing of gear sleeves. However, because Germany adopts advanced cycloidal theory to process grooves, the burrs generated by gear sleeves are small and thin, and can be easily removed. ;Due to the different processing methods of domestic gear sleeves (using machining centers with forming milling cutters), the burrs are hypertrophic, so that the German deburring technology cannot be directly adopted; in addition, German machine tools do not consider the burrs on the missing teeth of the gear sleeve splines. Requires manual file removal
