[0002] Shaft parts can be made of bar stock, forgings and other blank forms according to the use requirements, production type, equipment conditions and structure. For shafts with similar outer diameters, bar stock is generally used, while for stepped shafts or important shafts with large differences in outer diameters, forgings are often used. This not only saves materials and reduces the workload of machining, but also improves mechanical properties. Shaft parts are rotating parts with a length greater than the diameter. They are composed of an outer cylindrical surface, a conical surface, an inner hole, a thread and the corresponding end faces.

[0003] At present, slender shaft products will have irregular bending deformation after forging or heat treatment. In order to ensure subsequent processing and reduce the defective rate, it is necessary to roughly correct the roughness of the shaft products without center holes to ensure that their radial runout is within a reasonable range. Shaft products are often straightened by manpower, but the straightness is low and the labor cost is also high. Some equipment has poor flexibility during operation and the accuracy of straightening shaft products is poor. Therefore, a straightening device for shaft products without center holes is needed to improve the above problems. Utility Model Content
