Self-lubricating shaft sleeve chamfering device

Abstract

The self-lubricating shaft sleeve chamfering device comprises a rack and a tool rest movably connected to the rack, and a cleaning part is arranged on the tool rest; the cleaning part comprises a protection cleaning head, the protection cleaning head is in sliding connection with the tool rest through a moving shaft, the sliding direction of the protection cleaning head is the same as the sliding direction of the tool rest on the rack, and a mounting base is arranged at the end, away from the tool rest, of the moving shaft; the protective cleaning head is arranged, when chamfering cutting is carried out, the protective cleaning head can protect the inner surface of a shaft sleeve from being scratched by cutting chips and preventing copper powder from being embedded, the quality of the inner surface of a product is improved, the machining procedure of manual cleaning is reduced, and the labor cost is reduced; the production efficiency is improved.

Description

technical field [0001] The invention relates to mechanical cold processing equipment, in particular to a self-lubricating shaft sleeve chamfering device. Background technique [0002] The self-lubricating bushing is made of a three-layer composite self-lubricating material composed of a steel back, a copper powder layer and a self-lubricating layer. In the processing technology of this kind of bushing, both ends of the bushing need to be chamfered inside and outside. In the traditional Generally, a general-purpose chamfering machine is used in the process. Since the inner surface of the shaft sleeve is a soft plastic layer, it is very easy to cause scratches on the plastic layer, copper powder embedded or attached to the inner surface during the chamfering process, and affect product quality. After the processing is completed, it is necessary to manually pick out the copper powder and clean the surface, resulting in increased labor costs and reduced production efficiency. ...
