Description

A high-end CNC lathe step execution end pressure chuck

Technical field

The invention relates to the field of electromechanical equipment, and in particular to a high-end CNC lathe step execution end pressure chuck.

Background technique

With the development of the automobile industry, the requirements for production efficiency and precision of planet carrier and gear processing are getting higher and higher. Currently, when the planet carrier needs to press the window part, due to the small size of the rectangular window, ordinary end pressure chuck cannot be used, and it is required. Changing the clamping standard will lead to a large deformation in the final accuracy difference; another example is planetary gears or side gears, which need to press the arc above the teeth. However, due to the limitations of the movement of ordinary tooling fixtures, the inner hole and teeth of the planetary side gears will be damaged. The upper arc cannot be processed at one time because the tool will interfere with the fixture. However, the sequential processing of the arc and the coaxiality of the inner hole requires two machine tools, which consumes a lot of manpower, time and cost.

Therefore, there is an urgent need for a clamp that can avoid tool interference and ensure coaxial accuracy.

In summary, a high-end CNC lathe step execution end pressure chuck is needed to solve the deficiencies in the existing technology.
