Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a clamping tool for processing aluminum alloy wheel hubs. 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 the diameter, width, molding method, and material.

[0003] Aluminum alloy wheel hub is a common automobile wheel hub. When processing the aluminum alloy wheel hub, it needs to be clamped and fixed first. Chinese patent CN218800582U discloses a tooling positioning device for machining aluminum alloy wheel hub, including: a positioning device workbench, the surface of the positioning device workbench is evenly opened with six groups of openings, and the first clamping column, the second clamping column, the third clamping column, the fourth clamping column, the fifth clamping column and the sixth clamping column are respectively installed inside the six groups of openings, and the aluminum alloy wheel hub is placed on the surface of the positioning device workbench, and the aluminum alloy wheel hub is clamped and fixed on the positioning device workbench by the first clamping column, the second clamping column, the third clamping column, the fourth clamping column, the fifth clamping column and the sixth clamping column. In the tooling positioning device for machining the aluminum alloy wheel hub, six groups of servo electric cylinders work simultaneously, and the piston rod of the servo electric cylinder drives the clamping column to move, so that the first clamping column, the second clamping column, the third clamping column, the fourth clamping column, the fifth clamping column and the sixth clamping column move synchronously toward the aluminum alloy wheel hub, and the aluminum alloy wheel hub is clamped, which is convenient for processing the aluminum alloy wheel hub.

[0004] When processing a wheel hub, it is often necessary to process both the upper and lower surfaces of the wheel hub. Although the above patent can clamp and fix the wheel hub, the wheel hub cannot be turned over after being clamped and fixed. After the upper surface of the wheel hub is processed, the wheel hub needs to be loosened, and then the wheel hub is turned over manually, and then the wheel hub is clamped to process the other surface, which is more troublesome. Therefore, in view of the above situation, it is urgent to develop a clamping tool for aluminum alloy wheel hub processing that is convenient for clamping the wheel hub, convenient for turning the wheel hub up and down, and convenient for processing, so as to overcome the shortcomings in current practical applications and meet current needs.
