Description

Technical Field

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

[0002] The automobile wheel hub refers to a cylindrical metal part whose inner contour supports the tire and whose center is mounted on the shaft. It is also called a wheel rim or steel rim. It is an important part that connects the brake drum or brake disc, wheel disc and half-axle. It cooperates with the tire to support the wheel and can also determine the specifications of the tire. It is an indispensable component in the car. During the processing of the wheel hub, a fixing fixture is needed to position the wheel hub.

[0003] The patent publication number of the inspection institute CN217045471U discloses a clamp for processing automobile wheel hubs, including a base, a workbench is provided above the base, a rotating mechanism for rotating the workbench is provided between the workbench and the base, a fixing rod is fixedly connected to the upper end face of the workbench, a disc is fixedly connected to the end of the fixing rod away from the workbench, two symmetrically arranged through grooves are provided on the upper end face of the workbench, an L-shaped rod is provided in the through groove, and a clamping mechanism for clamping the wheel hub is provided at the end of the L-shaped rod located above the through groove. The utility model fixes the wheel hub on the workbench with the disc as the center point by turning the handle so that two arc-shaped plates are used to fix the wheel hub on the workbench with the disc as the center point, and then the main power is provided by the power motor and the two rollers cooperate with the annular groove to make the workbench rotate stably, so that various angles of the wheel hub can be processed, which improves the practicality of the device while increasing work efficiency.

[0004] However, this patent still has some shortcomings. When the wheel hub is fixed, the bottom of the wheel hub will be completely blocked by the workbench.
