Description

Technical Field

[0001] The utility model relates to an auxiliary tooling for a magnetic polishing machine, belonging to the technical field of grinding equipment. Background Art

[0002] The skin lattice structure is an ideal material for satellite structural panels. It consists of two layers of thin-walled skin and a regularly arranged lattice structure in the middle. Figure 1 As shown, the current forming processes for skin lattice structures on the market mainly include metal powder laser melting 3D printing technology and 3D printing combined with precision casting technology.

[0003] The metal powder laser melting 3D printing technology of the skin lattice structure mainly uses the printing equipment to stack the metal powder layer by layer and melt it into shape. Its molding size is limited by the size of the equipment, the production cycle is long, and the cost is high. The maximum size of the skin lattice structure under this technology is about 1200mm×1500mm. 3D printing is combined with precision casting technology to produce the skin lattice structure, mainly using 3D printing and investment casting technology, with a short production cycle, low cost, and large-scale mass production. The maximum molding size has exceeded 2 meters. Its main process steps are making wax molds, embedding gypsum, baking demolding, and pouring molding.

[0004] In the prior art, the skin lattice structures produced by metal powder laser melting 3D printing technology and 3D printing combined with precision casting technology have requirements for internal polishing of the lattice and the smoothness and cleanliness of the lattice. The use of magnetic grinding to clean the inside of the lattice is usually affected by the product size and requires customization of equipment larger than the product size for internal cleaning of the lattice. This causes a sharp increase in the post-production processing costs of large-sized and extra-large-sized skin lattice structures. Utility Model Content

The upper end of the supporting base is provided with a threaded column. The threaded column is screwed in the thread groove. Rotating the supporting base can adjust the length of the threaded column inserted into the thread groove.
