[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts.

[0003] Currently, there is a feeding device for shaft tube production with patent number 201921027775.2, which includes a base, a processing table fixedly connected to the top of the base, a support plate fixedly connected to the top of the base is arranged on one side of the processing table, a slide groove is provided on the front of the support plate, a slider is movably connected to the inner wall of the slide groove, a feeding plate is fixedly connected to the front of the slider, a feeding rod is fixedly connected to the front of the feeding plate, a support rod fixedly connected to the top of the base is arranged on one side of the support plate, one end of the support rod is fixedly connected to a slideway, a bearing is fixedly connected to the front of the slideway, and the bearing includes an outer shaft. The feeding device for shaft tube production achieves the purpose of saving space, solves the problem of wasting space in general feeding devices for shaft tube production, saves space for feeding work, and other work can be completed using the saved space, saving manpower and material resources, having a good use effect, and meeting people's needs.

[0004] However, the above patent has the problem of poor limiting effect on the shaft tube during loading after improvement, and does not have the function of correcting the position of the shaft tube, which makes the shaft tube easy to be skewed or offset when being transported on the conveyor line. There is also the risk of rolling during transportation, which will affect the stability of the shaft tube during loading and transportation. In addition, the existing loading mechanism requires manual arrangement of the shaft tubes in sequence before loading, and cannot realize automatic arrangement and loading of the shaft tubes. For this reason, we propose an automatic loading device for shaft processing. Utility Model Content
