Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheel hub processing, in particular to a clamping structure for preventing the wheel hub from moving. Background Art
[0002] After the casting of aluminum alloy wheels is completed, they need to go through a machining process to process the wheel blank into a finished product with dimensions and appearance that meet quality requirements. At present, during the first-order machining process of the wheel blank, the support block used to position the wheel hub is usually a flat block. During the machining process, the wheel hub is subject to the feed and cutting force of the tool, which is prone to movement and a certain amount of positional deviation, affecting the machining accuracy of the wheel hub. Especially in the latter part of the tool life cycle, after the machining tool inevitably wears and ages to a certain extent, the radial thrust acting on the wheel hub during the cutting process will increase significantly, which can easily cause the wheel hub blank to move, resulting in deviations in the wall thickness of the wheel hub, and even causing waste. There is also a quality risk of waste products being miscirculated due to wall thickness deviation. In addition, the dynamic balance of the wheel hub with wall thickness deviation will also be out of tolerance. During the clamping process, since the clamping end face is a continuous end face, the clamping position is not fixed each time, which will make it difficult to adjust the balance of the wheel hub and the balance failure rate is high.
[0003] Based on this, developing a clamping structure to prevent wheel hub movement and applying it to actual production is an issue that needs to be solved urgently. Utility Model Content
[0004] The utility model aims to provide a clamping structure for preventing the wheel hub from moving in view of the above problems, so as to solve the problem that the wheel hub is prone to moving during the existing wheel hub processing, resulting in wall thickness deviation and the inability to ensure processing quality.

The false wheel lip of the wheel hub blank is connected to the support plate via the limiting structure, so that the wheel hub blank is firmly connected to the support plate by the limiting action of the limiting structure.
[0007] Preferably, the limiting structure is an anti-skid tooth provided on the support plate, and the anti-skid tooth forms a serrated structure on the support plate for contacting the hub blank.

[0009] Preferably, inclined surface structures are provided on both sides of the limiting ridge, and the inclination of the inclined surface structure is equal to the inclination of the clamping groove of the hub blank.
[0010] Preferably, the edges of the limiting ridge are provided with rounded corners, so that the limiting ridge can lie smoothly into the clamping groove.
[0011] Preferably, the limiting structure is a limiting notch arranged on the support plate, and the limiting notch is arranged corresponding to the outer edge of the false wheel lip of the hub blank, so that the outer edge of the false wheel lip can lie in the limiting notch.
[0012] Preferably, the support plate is provided with a fixing hole for connecting to the base, so that the fastening bolt can pass through the fixing hole and be connected to the base, thereby achieving connection and fixation between the support plate and the base.

When in use, the false wheel lip of the wheel hub blank to be processed is placed on the support plate 2, and then the wheel hub blank is pressed by the pressing claws to complete the positioning and clamping of the wheel hub blank. In order to improve the problem that the wheel hub blank is prone to moving during the processing and affects the processing accuracy, a limiting structure 3 for limiting the movement of the wheel hub blank is provided on the support plate 2, and the false wheel lip of the wheel hub blank is connected to the support plate 2 through the limiting structure 3, so that the wheel hub blank is firmly connected to the support plate 2 by the limiting effect of the limiting structure 3, thereby avoiding the position movement of the wheel hub blank during the processing and ensuring the processing accuracy.
[0026] First embodiment:
[0027] As a first embodiment of the utility model, the limiting structure 3 is an anti-skid tooth 31 provided on the support plate 2, and the anti-skid tooth 31 forms a serrated limiting structure 3 on the support plate 2 for contacting the hub blank. When in use, the false wheel lip of the hub blank is supported on the anti-skid tooth 31, and then pressed by the pressing claws, so that the anti-skid tooth 31 is firmly pressed on the false wheel lip of the hub blank, so as to achieve the purpose of limiting the movement of the hub blank. In this embodiment, the anti-skid tooth 31, with its sharp serrated structure, can be slightly embedded in the false wheel lip surface of the hub blank during the pressing process, forming a stable clamping of the hub blank.

In this embodiment, the positioning clamping of the hub blank is achieved through the plug-in cooperation between the limiting ridge 32 and the clamping groove. Compared with the first embodiment, this embodiment avoids the problem that the anti-slip teeth 31 are easy to wear and affect the limiting effect, and has a long service life.
[0030] Preferably, inclined surface structures 321 are provided on both sides of the limiting ridge 32, and the inclination of the inclined surface structure 321 is equal to the inclination of the hub blank mounting groove.
