Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mechanical part processing, and particularly relates to a polishing device for mechanical part processing. BACKGROUND

[0002] Mechanical part processing refers to a process of treating raw materials through a series of processes to make the shape, size and performance of the part meet the design requirements. The process includes various process methods, among which cutting processing is to remove materials by using a tool to achieve the required shape and size; and forging processing is to apply pressure to metal to produce plastic deformation, thereby obtaining a specific organizational structure and performance. In mechanical part processing, part polishing is an important surface treatment process. The main purpose is to remove burrs, scale and other defects on the surface of the part to improve the surface finish and quality. During polishing, appropriate abrasive and polishing method need to be selected according to the precision requirements of the part. For parts with low precision requirements, relatively coarse abrasive can be used for preliminary polishing to quickly remove obvious surface defects; for parts with high precision requirements, fine abrasive needs to be used for long-time polishing to ensure that the surface meets the specified roughness and flatness requirements. After polishing treatment, the part can better meet the use requirements and improve the overall performance and reliability of the product.

[0003] When polishing tubular parts, steel pipe polishing equipment is used. The existing steel pipe polishing equipment is mainly of two forms. The first form of polishing equipment polishes the steel pipe without changing the position of the steel pipe, and drives the steel pipe to rotate and polishes the steel pipe through a translatable polishing head. For example, the Chinese utility model patent with the publication number CN210139294U supports the steel pipe through a support mechanism, drives the steel pipe to rotate through a rotating drive mechanism, and polishes the steel pipe through a translatable polishing mechanism. Although this form of polishing equipment can polish the steel pipe, the translatable distance of the polishing mechanism is limited by the size of the equipment itself, so this form of polishing equipment can only process steel pipes with a length less than the equipment, and cannot process longer steel pipes. In order to adapt to longer steel pipes, this polishing equipment is often long in size and large in floor area, which wastes the space of the factory building.

[0004] Another form of polishing device, the position of its polishing mechanism does not change during polishing, and the steel pipe is driven to rotate and translate by a feeding roller and a set of inclined guide wheels, so that the polishing mechanism can polish the steel pipe as a whole, such as the Chinese invention patent with publication number CN119077595A, which drives the feeding roller to rotate by motor one, chain wheel and chain, thereby driving the steel pipe to rotate, the steel pipe drives the inclined guide wheel to rotate by friction, under the action of the inclined guide of the inclined guide wheel, the stainless steel pipe rotates at the same time with the stable rate to the polishing assembly, although the polishing device of this structure can drive the steel pipe to translate, it can be used for processing the steel pipe longer than the device itself, but this polishing device drives the inclined guide wheel to rotate by the rotation of the feeding roller and the rotation of the steel pipe, so as to realize the axial movement of the steel pipe, the speed of the axial movement of the steel pipe is highly positively correlated with the rotation speed of the steel pipe itself, when processing steel pipes of different specifications, different roughness and different polishing precision, the device cannot change the ratio of the steel pipe rotation speed to the steel pipe translation speed, and the moving speed of the steel pipe remains constant during the polishing and polishing process, so it cannot accurately adjust the length of time when the polishing mechanism and the steel pipe locally contact according to the processing requirements, in addition, the device keeps the steel pipe stable by vibration sensor, controller, motor and negative pressure adsorption mechanism and other structures to avoid the vibration of the steel pipe, the anti-vibration mechanism has the problems of complex structure and limited anti-vibration effect.
