Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub processing, in particular to an automobile wheel hub processing deburring device. Background Art

[0002] In the automotive manufacturing industry, wheels are an essential component of automobiles, and their quality and precision directly impact their performance and safety. With the continuous development of the automotive industry, the requirements for wheel processing quality are becoming increasingly stringent. During the wheel processing process, due to cutting and casting processes, a large number of burrs often form on the wheel surface. These burrs not only affect the wheel's appearance quality but can also adversely affect subsequent assembly and use, necessitating deburring.

[0003] In the prior art, traditional deburring devices mostly use a grinding wheel to grind the hub surface to achieve the purpose of deburring. For example, a hub deburring machine proposed in application number CN108705405A, when in use, uses a processing station to drive the hub to rotate so that the hub and the grinding wheel rotate together to complete the grinding. However, this method has major defects. For example, due to the different sizes of hubs, this method is very inconvenient when processing hubs of different sizes. Therefore, the utility model proposes a vehicle wheel hub processing and deburring device to solve the above problems. Utility Model Content

[0007] Preferably, the lifting mechanism includes two electric push rods respectively fixedly connected to the upper ends of the two fixed plates, and the telescopic ends of the two electric push rods are both fixedly connected to the movable plate.

[0008] Preferably, the clamping mechanism comprises a slider slidably connected in a sliding groove, and a clamping plate is fixedly connected to a side wall of the slider.

[0009] Preferably, the inner walls of the four sliding grooves are all rotatably connected with first threaded rods, and the four first threaded rods respectively pass through four sliding blocks and are threadedly connected thereto.

[0010] Preferably, the second threaded rod passes through the side wall of the rotating plate and is rotatably connected thereto, and the end of the second threaded rod is fixedly connected to a handle.

[0011] Preferably, the lower end of the movable plate is fixedly connected to a first motor, and the end of the output shaft of the first motor is fixedly connected to the upper end of the rotating rod.

[0012] Preferably, one end of the four first threaded rods located in the groove is fixedly connected to a first bevel gear, a second bevel gear is rotatably connected in the groove, and the four first bevel gears are all meshed with the second bevel gear.

[0013] Preferably, a second motor is fixedly connected to the lower end of the base, and the end of the output shaft of the second motor is fixedly connected to the axis of the second bevel gear.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

By setting up a moving mechanism, rotating the handle drives the second threaded rod to rotate, thereby driving the moving block threadedly connected to it to move in the through groove, thereby driving the grinding assembly to move, and the distance between the grinding assembly and the rotating rod can be adjusted. During grinding, the rotating rod rotates to drive the rotating plate to rotate, and drives the grinding assembly to rotate with the rotating rod as the axis.
