[0019] Beneficial Effects

[0020] The utility model provides a novel quick-change tooling structure for CNC lathes. Compared with the prior art, it has the following beneficial effects:

[0021] 1. The new quick-change tooling structure for CNC lathes has two baffle bars fixedly connected at equal intervals on the surface of a rotating plate. A slide is sleeved on the surface of the rotating plate. Two slide grooves are arranged at equal intervals in the inner cavity of the slide.

This solves the problem that the CNC machine tool needs a fixture to clamp aluminum bars and other raw materials during cutting processing, and then rotates at high speed. This places high requirements on the positioning and center of gravity of the fixture. Deviation from the positioning and center of gravity will make the products fail to meet the requirements and become waste. In severe cases, the tool head will break and fly, which will injure the operator. There is a great risk, resulting in increased production costs and endangering the safety of the operator.

The slide plate 23 slides inside the slide groove 24, which solves the problem that when aluminum bars and aluminum plates are used to manufacture non-ferrous metal smelting and rolled products, CNC machine tools are needed to perform cutting processing. When performing cutting processing, the cutting process is simple, the type of fixture used is single, and cumbersome steps are required to load and unload the fixture and then replace it during loading and unloading, resulting in complicated and diverse operations, occupying production time, and wasting time and effort.

[0034] In this embodiment, the rotating assembly 3 includes:

[0035] The transmission part 31 is used to position the product. The transmission part 31 includes three arc rods 311 arranged above the fixed block 1, and the arc rods 311 are evenly distributed above the fixed block 1.
