Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, more specifically to a wheel hub processing fixture. Background Art

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

[0003] Since the wheel hub is cylindrical, it needs to be clamped during processing. The existing wheel hub processing fixture usually applies force to the outside of the wheel hub through the fixture to fix the wheel hub from the outside of the wheel hub, but there is no support on the inside of the wheel hub. Therefore, during the processing or handling process, the wheel hub may produce some undesirable deformation due to the external force, and the fixing stability is poor, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a hub processing fixture, which can limit and fix the inner and outer sides of the hub, effectively prevent the hub from deforming during processing, and improve the processing quality.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A wheel hub processing fixture comprises a workbench, a transmission groove is opened in the middle of the workbench, and four first sliding grooves are opened on the working upper surface evenly distributed around the circumference of the transmission groove, a pitch adjusting screw is rotatably arranged in the first sliding groove, one end of the pitch adjusting screw penetrates into the transmission groove and is fixedly connected with a bevel gear, and the four bevel gears are meshed with each other. A first driving motor that drives the pitch adjusting screw to rotate is installed on one side of the workbench, a sliding block is threadedly connected to the pitch adjusting screw, and the top of the sliding block is fixedly connected to a base, a second sliding groove is opened on the upper surface of the base, a bidirectional screw is rotatably arranged in the second sliding groove, both ends of the bidirectional screw are threadedly connected with mounting blocks, the mounting block is slidably connected to the second sliding groove, a fixture assembly is arranged on the mounting block, and a second driving motor that drives the bidirectional screw to rotate is installed at one end of the base.

[0007] Furthermore, the clamp assembly includes a first connecting rod vertically fixedly connected to the mounting block, and a limiting roller is rotatably sleeved on the first connecting rod.

[0008] Furthermore, a rubber pad is provided on the outer surface of the limiting roller.

[0009] Furthermore, the clamp assembly includes a second connecting rod vertically fixedly connected to the mounting block, and an arc-shaped limiting plate is fixedly sleeved on the second connecting rod.

[0010] Furthermore, rubber pads are provided on opposite sides of the two arc-shaped limit plates located above the same bidirectional screw.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] During processing, according to the size of the wheel hub workpiece that needs to be fixed, the first drive motor drives the pitch adjusting screw to rotate, driving the slider to slide along the first slide groove, and at the same time, through the engagement of the bevel gears, drives the four bases to move to the specified position, and then the wheel hub workpiece is placed between the inner and outer side clamp assemblies, and the second drive motor drives the bidirectional screw to rotate, driving the two mounting blocks to approach each other, so that the two clamp assemblies respectively limit and fix the inner and outer sides of the wheel hub, effectively preventing the wheel hub from deforming during processing, improving the processing quality, helping to ensure the safety of the processing process, and avoiding accidents caused by movement or instability of the wheel hub.
