[0002] Straightening machines are equipment for straightening metal profiles, bars, pipes, wires, etc. Straightening machines use straightening rollers to squeeze bars and other materials to change their straightness. Generally, there are two rows of straightening rollers, with varying numbers. There are also two-roller straightening machines, which rely on the angle change of two rollers (concave in the middle, hyperbolic rollers) to straighten materials of different diameters. The main types include pressure straightening machines, balance roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc., which need to be corrected when processing shaft parts to ensure that the shaft has reliable stability when rotating.

[0003] However, there are still some problems when using the existing automatic straightening machines for shaft parts processing:

[0005] The existing shaft straightening machines have certain problems in loading and unloading operations when processing shaft parts. If the diameter of the shaft parts is thicker, the weight must be heavier. If the loading and unloading is done manually, it is not only difficult to operate, but also prone to safety hazards during the loading and unloading process.

[0006] The existing straightening machines have a low overall straightening efficiency. They use a three-jaw chuck for clamping. First, the stability is low. The one-way clamping cannot guarantee the stability of the shaft parts during rotation. At the same time, the operation of the three-jaw chuck is relatively inconvenient.

[0007] Aiming at the above problems, an innovative design was carried out based on the original automatic straightening machine for processing shaft parts. Summary of the invention
