Description

Technical Field

[0001] The utility model belongs to the technical field of shaft sleeve processing, and particularly relates to a shaft sleeve forming device with double-sided chamfering. Background Art

[0002] A bushing is a mechanical part, usually a cylindrical part made of metal or other materials, whose main function is to reduce friction and wear. Bushings are installed on mechanical equipment to support, position and reduce friction between the shaft and the hole. During the operation of mechanical equipment, gaps may occur between the shaft and the hole. These gaps may cause wear and equipment failure when rotating at high speeds, and bushings reduce friction by filling these gaps, thereby extending the service life of the equipment. Bushings are also used to protect the shaft itself, prevent it from directly contacting with external hard substances, reduce noise and vibration of mechanical equipment, and improve work efficiency. Bushings are widely used in various machinery and equipment, such as automobiles, railways, ships, excavators, steel, mining and other industries. Bushings need to be chamfered by a chamfering machine during the processing process to facilitate the installation of bushings.

[0003] After searching, the Chinese patent with announcement number CN219648855U discloses a sleeve processing chamfering device, which includes a rotating fixture: a workbench is fixedly installed at the bottom of the rotating fixture, a material box is fixedly installed on the top of the workbench, and a cylinder 1 is fixedly installed on the right side of the top of the workbench. The utility model can control the up and down movement of the rectangular tube through cylinder 2, and the workpiece to be processed can be clamped on the surface of the conveyor belt through the cooperation of cylinder 3 and the lower pressure plate. Through the cooperation of motor 2, roller, conveyor belt and electric slide rail, the workpiece to be processed can be moved to the clamping cavity of the rotating fixture and taken out. The workpiece to be processed can be adjusted to rotate half a circle through motor 1, three frames and rectangular tubes, and the workpiece to be processed can be rotated half a circle and pushed into the inner cavity of the rotating fixture again, so that the single-head chamfering device can chamfer both ends of the sleeve, reducing the number of times the sleeve is put into the material feeding device, thereby reducing the labor intensity of the staff. Although the device can realize double-sided chamfering of the sleeve, the whole operation process is complicated and cumbersome, and the two chamfering actions are repeated many times, which greatly affects the production efficiency of the sleeve.
