Description

Technical Field

[0002] Fire fittings are an important part of the fire protection system, mainly including fittings for connection and sealing, such as rigid joints, flexible joints, mechanical tees and grooved flanges; fittings for connection and transition, such as elbows, tees, crosses, reducers, blind plates, etc. Fire fittings are usually made of cast iron, stainless steel, copper, plastic, etc., among which cast iron and stainless steel are the most widely used.

[0003] During use, fire-fighting pipe fittings generally need to be matched with fire-fighting pipes, and their matching positions often require high precision. Therefore, when processing fire-fighting pipe fittings, it is necessary to grind the outer surface of the fire-fighting pipe fittings so that the outer surface has good smoothness to ensure the accuracy during subsequent use.

[0004] After searching, the Chinese invention patent application with application number "202311571091.X" discloses a grinding and polishing machine tool equipment, which relates to the field of grinding technology; in order to solve the problems of grinding efficiency and grinding quality; specifically includes a base, a fixed frame fixed on the top of the base, and a sliding frame matched with the top of the base through a linear drive unit, the top outer wall of the fixed frame is fixed with a three-jaw chuck, and the top of the sliding frame is provided with a grinding part, and the claws of the three-jaw chuck are matched with the shaft to be polished through ball rolling; the grinding part includes a gear ring embedded in the inner wall of the sliding frame, a plurality of planetary gears meshed with the inner side wall of the gear ring, and a sun gear meshed with the inner side of the plurality of planetary gears.
