[0002] An all-terrain vehicle is a vehicle that can travel on any terrain and can move freely on terrain where ordinary vehicles are difficult to maneuver. It is commonly known as a beach buggy in China. The wheel hub is also called the rim. Depending on the characteristics and needs of different models, the wheel hub surface treatment process will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The wheel hub needs to be clamped and fixed by a fixing device during processing.

[0003] An existing patent (publication number: CN220825694U) discloses a wheel hub machining and fixing device comprising a base plate, a first mounting plate fixed to its upper surface, a second mounting plate fixed to its upper surface, and a fixing mechanism disposed within the first mounting plate. During implementation of this solution, the following problems were discovered in the prior art, which have not been adequately addressed: During use, the device requires rotating a handle to control the retraction of a second threaded block to clamp the wheel hub, and then requires a motor to control the downward movement of a support roller to secure the wheel hub. However, in this case, the wheel hub is relatively low, and when the wheel hub is rotated during machining, the friction between the second threaded block and the wheel hub makes it difficult to rotate, making machining the wheel hub more difficult for the operator. Utility Model Content

[0004] In order to improve the problem that the above-mentioned device controls the retraction of the second threaded block and clamps the wheel hub by turning the handle during use, and then needs to control the support roller to move down and fix the wheel hub by the motor, however, the height of the wheel hub is relatively low at this time, and the friction between the second threaded block and the wheel hub when the wheel hub is rotated during processing makes it difficult for the operator to rotate the wheel hub, so it is more troublesome for the operator to process the wheel hub. The utility model provides a beach car wheel hub processing and fixing device.

[0005] The utility model provides a beach car wheel hub processing and fixing device, which adopts the following technical solutions:

[0006] A beach car wheel hub processing and fixing device includes a bracket, a first slide groove is opened on the inner side of the bracket, a driving rod is arranged in the first slide groove, a supporting plate is threadedly sleeved on the driving rod, a second slide groove is opened inside the supporting plate, a gear rod is rotatably arranged in the second slide groove, a tooth plate opposite to the gear rod is provided on the inner side of the bracket, the tooth plate is meshed with the gear rod, and clamping parts are threadedly sleeved on both ends of the gear rod, the clamping part is movably arranged in the second slide groove, and a rotating part is provided on the top of the bracket.

[0007] Through the above technical solution, the wheel hub is first placed on the supporting plate, and then the driving rod is started to control the supporting plate to move up.

[0012] Optionally, in the above-mentioned beach car wheel hub processing and fixing device, both ends of the gear rod are provided with external threads, and the thread directions of the two external threads are opposite, and two transmission gears are symmetrically arranged on the gear rod.

[0019] Through the above technical solution, when the bearing plate moves up, the wheel hub is forced to abut against the pressure plate, and the rubber rod is pushed down by the spring to abut against the wheel hub, thereby increasing the friction between the pressure plate and the wheel hub.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] When the carrying plate moves up, the wheel hub is forced to abut against the pressure plate, and at the same time the height of the wheel hub is increased. The spring pushes the rubber rod downward and abuts against the wheel hub, thereby increasing the friction between the pressure plate and the wheel hub. Then the second motor drives the pressure plate to rotate, thereby driving the wheel hub to rotate through the pressure plate, making it easier for the operator to process the wheel hub.

[0022] First, place the wheel hub on the supporting plate, then start the driving rod to control the supporting plate to move up. As the supporting plate moves up, the gear rod is driven to rotate through the tooth plate and the two clamping parts are controlled to contract, thereby clamping and fixing the wheel hub through the clamping parts.
