Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub processing, in particular to a wheel hub fixing device used for automobile wheel hub processing. Background Art

[0002] The wheel hub fixing device used for automobile wheel hub processing is a device used to firmly fix the wheel hub during the wheel hub processing process. It has the characteristics of large clamping force, good rigidity, and high stability. It can ensure that the wheel hub does not move or deform during the processing process, thereby ensuring processing accuracy and efficiency. The device is usually composed of a clamp, a bracket, a drive system and a control system. The clamp is used to clamp the wheel hub, the bracket is used to support the clamp and the wheel hub, the drive system is used to drive the movement of the clamp, and the control system is used to control the operation of the entire device. Through the application of the wheel hub fixing device, not only the degree of automation of wheel hub processing can be improved, but also the quality and efficiency of wheel hub processing can be improved and production costs can be reduced.

[0003] According to the search of China Utility Model Publication No.: CN220680247U, a fixing device for processing automobile wheel hubs is disclosed. The utility model can rotate the entire fixing assembly by cooperating with the rotating rod, worm and turbine arranged on the bottom wall of the groove through the rotating table arranged inside the groove. During operation, the first bevel gear is driven by the motor, and the first bevel gear drives the second bevel gear. The rotation of the second bevel gear can drive the rotation of the rotating rod, and the rotation of the rotating rod drives the rotation of the worm, and the turbine can be driven by the worm to rotate, and then the rotation of the entire rotating table is driven. The rotating table can drive the entire fixing assembly to rotate, which solves the problem that the fixing device cannot drive the wheel hub to rotate when processing its surface, and the staff needs to process and polish around the wheel hub, which has low adaptability, increases the workload of the workers, and affects work efficiency.

[0027] Specifically, the inner side of the placement table 301 is rotatably connected to the rotating table 302, and one side of the rotating table 302 is rotatably connected to the moving motor 303. The moving motor 303 is fixedly connected to the base 1. When the moving motor 303 works, the rotating table 302 rotates.

[0029] Specifically, the connecting block 309 is fixedly connected to the limiting rod 306, and multiple groups of connecting blocks 309 are provided. A first telescopic rod 310 is provided between the connecting blocks 309. The connecting block 309 forms a movable structure through the first telescopic rod 310 and the limiting rod 306.

[0034] Working principle: First, the rotating motor 316 drives the rotating arm 315 to rotate to prevent the pressure plate 318 from affecting the wheel hub removal and placement, and the wheel hub is placed on the placement table 301. Then the first telescopic rod 310 extends to adjust the height of the connecting block 309 to clamp the wheel hub at a higher height stably. Then the moving motor 303 works to rotate the rotating table 302, and the relative positions of the straight limit groove 304 and the curved limit groove 305 change, so that the limit rod 306 moves, and the slider 308 moves in the slide groove 307 to move the connecting block 309. Then the second telescopic rod 312 extends and retracts to adjust the clamping The holding arm 311 is angled so that the connecting block 309 fits against the wheel hub to fix the wheel hub and adapt to wheel hubs of different diameters. After the fixing block 313 fits against the wheel hub, the wheel hub is fixed and stable. The rubber material has good elasticity and can absorb and disperse the impact and vibration generated during the clamping process, protecting the clamped object from damage. The surface protrusions can increase the friction between the fixing block 313 and the wheel hub, thereby improving the stability of the fixation.
