Problems solved by technology

[0003] However, most of the current back shaft chucks of the centering machine are three-petal self-centering chucks, which can only clamp some rotating shaft parts. When encountering some special-shaped parts with high dimensional accuracy requirements, only increase It is completed in one process, so it has an additional process, the process is cumbersome, and consumes a lot of time for no reason; at the same time, it increases additional costs; increases the risk of poor size

Abstract

The invention relates to the technical field of machinery, and more particularly, the invention relates to a special-shaped chuck for the back shaft of a walking machine and a production process thereof. The special-shaped chuck for the back shaft of the walking machine includes a first chuck handle 1, a chuck body 2 and a boss 3 connected in sequence, and the first chuck handle 1, the chuck body 2 and the boss 3 are integrally connected; The first collet handle 1, the collet body 2 and the peripheral wall of the boss 3 are machined with two notch grooves 4, and the corresponding positions of the 2 notch grooves 4 are parallel to each other; the top of the boss 3 is provided with a clamping cavity 5. The special-shaped chuck for the back shaft of the centering machine provided by the invention can clamp the special-shaped products, and the clamping is stable, which ensures the need for processing the special-shaped products with only one operation, and avoids additional processes. The back shaft special-shaped collet has a long service life and can be used for processing 500,000 products without deformation.

Description

technical field [0001] The invention relates to the technical field of machinery, and more particularly, the invention relates to a special-shaped chuck for the back shaft of a walking machine and a production process thereof. Background technique [0002] The chuck of the walking machine is installed at the front end of the main shaft or the back shaft, and plays the role of clamping the raw materials and products to move back and forth with the main back shaft. [0003] However, most of the current walking machine back shaft chucks are three-lobed self-centering chucks, which can only hold some shaft-like rotating parts. When encountering some special-shaped parts and high dimensional accuracy requirements, only increase It is completed by one process, so it has an additional process, which is cumbersome and consumes a lot of time for no reason; at the same time, it increases the extra cost and increases the risk of poor size. SUMMARY OF THE INVENTION [0004] In view o...
