Description

Polishing device is used in production of 3D printing accessory Technical Field The utility model relates to the technical field of 3D printing, in particular to a grinding and polishing device for 3D printing accessory production. Background The 3D printing accessory is a component manufactured by a 3D printing technology. The 3D printing can precisely manufacture various accessories with complex shapes according to a specific design model by using a mode of stacking materials layer by layer. Compared with the traditional manufacturing mode, the 3D printing accessory has high customization and can meet different personalized requirements. It can quickly make prototype and shorten the development period of product. However, 3D printing accessories have certain drawbacks. In many fields, the surface flatness of the parts is guaranteed, and the surface texture of the 3D printed product cannot meet the requirement. At present, the polishing mode is mostly adopted to remove the layer patterns, and the method has the advantages of manual polishing, high controllability, slow efficiency and vibration polishing machine, but also has the defects. Firstly, parts such as bolts in the polishing cylinder are easy to scratch the accessories, secondly, the accessories are usually small in size, and no matter the accessories are checked after polishing or the progress is checked in the polishing process, the accessories are required to be salvaged from polishing sand after stopping, so that the accessories are troublesome and frequent stopping is required. Disclosure of utility model The utility model provides a double-cylinder design for solving the problems, which ensures the protection effect on accessories, limits the accessories to a certain extent and can take out the accessories without stopping the machine. In order to solve the technical problems, the technical scheme is that the polishing device for 3D printing accessory production comprises a base, wherein a polishing outer cylinder is detachably arranged on the base, a polishing inner cylinder is detachably arranged in the polishing outer cylinder, a plurality of hanging frames are arranged at the edge of the upper part of the polishing inner cylinder, the hanging frames are hung on the edge of the upper part of the polishing outer cylinder, a plurality of supporting rods are fixedly arranged around the polishing outer cylinder above the base, telescopic rods are rotatably arranged at the upper ends of the supporting rods, and hanging ropes for fixing 3D printing accessories are connected to the extending ends of the telescopic rods. Furthermore, a plurality of anti-slip adhesive tapes are arranged below the base. Based on the characteristics, the anti-slip adhesive tape can increase the friction force between the whole device and the placing surface, ensure that the device cannot easily slide or shift in the polishing process, and ensure the stability and safety of operation.
