Machined part surface polishing device

Abstract

The invention discloses a machined part surface polishing device and relates to the technical field of machining. The device comprises a supporting frame, wherein a polishing groove filled with quartzsand is installed in the supporting frame in a sliding mode, a sleeve is rotatably installed on the supporting frame, the sleeve is in transmission connection with a rotary stirring mechanism, a motor III is fixed to a side wall of the supporting frame, and a translation mechanism used for driving the polishing groove to move in the transverse direction is driven by the motor III. The device is advantaged in that the quartz sand and parts in the grinding groove can be rotationally stirred through the arranged rotary stirring mechanism, surfaces of the parts are fully rubbed by the quartz sand, the surfaces of the parts are quickly and fully polished, the rotating directions of a stirring frame and a dispersing plate on the hollow shaft are opposite, the stirring effect of the quartz sandand the parts is more sufficient, polishing efficiency is remarkably improved, an arranged lifting mechanism can drive the rotating stirring mechanism to ascend and descend in the vertical direction,and that the parts in the polishing groove are fully and thoroughly polished by the quartz sand is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a surface polishing device for mechanical processing parts. Background technique [0002] Mechanical parts, also known as mechanical components, are the basic components of machinery, and they are inseparable individual parts that make up machinery and machines. Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. During the production and processing of some mechanical parts, it is usually necessary to mix the parts with quartz sand, and through mutual agitation and friction, the surface of the mechanical parts can be polished. [0003] The patent application publication number CN208575659 U discloses a mechanical parts polishing equipment. A sprocket is installed on the frame, and a chain ...

AI Technical Summary

Problems solved by technology

[0003] The patent application publication number CN208575659 U discloses a mechanical parts polishing equipment. A sprocket is installed on the frame, and a chain is wound around the sprocket. There is a track on the track plate, and the track plate is slidingly connected to the bottom of the workbench through the track. An emery roller is installed on the top of the workbench, and the polishing motor is connected to the emery roller. One side of the workbench is fixed with a suction pipe. There are several suction nozzles distributed on the dust suction pipe, the air inlet of the fan is connected with the dust suction pipe through the pipeline, and the air outlet of the fan is connected with the collection box; a number of positioning screw holes are arranged on the described workbench, although the device can Mechanical parts are polished, but the parts cannot be fully polished, and the polishing efficiency is low. For this reason, a surface polishing device for mechanically processed parts is now provided to solve the above technical problems
