Abstract

The invention relates to the technical field of 3D printing post-treatment, provides a surface polishing device for a 3D printing blank and an operation method, and aims to solve the problems of low manual polishing efficiency, poor product consistency and limit in improving the product surface roughness with abrasive particle flow and magnetic polishing in a surface treatment method for a 3D printing workpiece in the current industry. The surface polishing device comprises a control system and a grinding mechanism, wherein the grinding mechanism comprises a working platform and protective partition plates symmetrically mounted on the two sides of the upper end of the working platform; a fixed arm is mounted at the upper end of one of the protective partition plates; the other end of the fixed arm is connected with a movable telescopic arm in which a built-in telescopic structure and a mechanical transmission system are built in through a rotary connecting unit; a movable arm is mounted at the tail end of the movable telescopic arm; a grinding head mounting base is arranged at the other end of the movable arm; and a grinding head is detachably mounted in the grinding head mounting base. The surface polishing device is particularly suitable for post-treatment of 3D printing core parts in the field of aerospace engines, and has high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of post-processing of 3D printing, in particular to a surface polishing device and an operation method of a 3D printing blank. Background technique [0002] With the continuous progress and development of 3D printing technology, 3D printing technology can basically meet the forming requirements of the core parts in the field of aerospace engines. The core parts in the field of aerospace engines are generally in service under high temperature and high pressure conditions. The surface quality directly affects the structural strength and heat transfer efficiency of the core. However, the surface quality of the workpiece after forming is not uniform, and there is uncertainty in the surface treatment control of thin-walled structures. This limitation has always restricted the further application and development of 3D printing technology in this field. [0003] At present, the surface treatment methods of 3D prin...
