Device for polishing annular groove

Abstract

The invention belongs to the technical field of inner surface machining, and particularly relates to a device for polishing an annular groove. The device comprises a workpiece clamping and rotating device and a feeding device, wherein the workpiece clamping and rotating device comprises a spindle box, a three-jaw chuck and a motor; and the feeding device comprises a lead screw I, a sliding rail, aslide carriage box and a workbench. The device is characterized in that a fixing frame is arranged on the workbench; a grinding device is connected with the fixing frame; an adjusting device is arranged below the workbench; and the grinding device comprises a clamping handle fixed to the fixing frame, an annular magnetic pole sleeve connected with the clamping handle, an annular magnetic pole arranged in the annular magnetic pole sleeve, a rubber ring arranged in the annular magnetic pole, a hollow cylinder arranged in the rubber ring, a packing device arranged in the hollow cylinder, and a cylindrical magnetic pole arranged at the end of a piston, wherein packing comprises a piston shaft, the piston and a piston handle. The device is simple in structure and ingenious in design, magneticgrinding materials are evenly distributed, the magnetic field intensity in a grinding area is evenly distributed, and the grinding effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of inner surface processing, in particular to a device for polishing an annular groove. Background technique [0002] Due to its structural characteristics, ring grooves are generally processed by turning, boring and milling. However, with the continuous development of the machinery manufacturing industry, the requirements for annular grooves are getting higher and higher. Conventional processing can no longer meet the processing requirements, such as surface damage such as burrs and microcracks, which requires grinding to ensure. Grinding can significantly improve the surface quality of the annular groove, prolong the service life of the sealing ring installed in the annular groove, ensure the sealing ability for a long time, and have great room for development. [0003] At present, grinding wheels are usually used for grinding annular grooves, but because of the high hardness of the grinding wheels, the s...

AI Technical Summary

Problems solved by technology

[0003] At present, the grinding of the annular groove is usually done by grinding wheel, but because of the high hardness of the grinding wheel, the sand particles are not easy to fall off during processing, and burns are caused after repeated grinding

Also, because the area involved in cutting is different, and the degree of wear inside and outside the grinding wheel is different, the bell mouth phenomenon appears consistently in the finished parts.
