Technical Field

[0001] The utility model relates to a driving spindle of a hub spinning machine which is easy to maintain and belongs to the technical field of driving spindles of spinning machines. Background Art

[0002] The wheel hub is a cylindrical metal component that supports the tire with its inner profile supported by the tire and is mounted on an axle in the center. It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheel hubs depending on their diameter, width, molding method, and material.

[0003] During the processing of the wheel hub, a spinning machine is required to spin-form the side of the wheel hub. During the use of the spinning machine, the spinning part at the upper end of the driving spindle is the main force-bearing end. After the driving spindle has been used for a period of time, the spinning part of the driving spindle will be worn and needs to be repaired and replaced. However, the existing driving spindle is generally an integrated structure. When repairing and replacing, the entire driving spindle needs to be removed from the spinning machine. Because the driving spindle has many matching parts on the spinning machine, the repair and replacement is difficult and time-consuming. In addition, the replacement of the entire driving spindle has a high maintenance cost. In view of the above problems, the utility model proposes a wheel hub spinning machine driving spindle that is easy to repair. Utility Model Content

[0007] A further improvement is that the spindle spinning part includes a spinning part, a sleeve opening extending through the middle of the spinning part, a first stabilizing component slot and a second stabilizing component slot being symmetrically provided on the side wall of the sleeve, and a plurality of screw holes being spaced around the top surface of the spinning part.

[0008] A further improvement is that the stable insert seat group includes a stable seat, an insert block arranged on the front side of the stable seat, a first section and a second section arranged on the left and right sides of the stable seat, a first slide track is opened on the first section, and a second slide track is opened on the second section.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a hub spinning machine driving spindle which is easy to maintain. The driving spindle and the spindle spinning part are designed to be disassembled in sections, and the first stabilizing component and the second stabilizing component are symmetrically offset between the driving spindle and the spindle spinning part, so that after the spinning part of the driving spindle is worn, only the spinning part needs to be disassembled and replaced, and the replacement operation is simple, time-saving and labor-saving, and the maintenance and replacement cost is low. The symmetrical offset design of the two stabilizing components makes the main rotational force between the driving spindle and the spindle spinning part on the two stabilizing components during spinning, so that the screw between the driving spindle and the spindle spinning part is fixedly connected. When the screw is rotated clockwise and counterclockwise for spinning, each screw is only subjected to a small force, which can prevent the screw from loosening or breaking, and improve the spinning connection stability between the driving spindle and the spindle spinning part.
