Refers to cars that are mainly used to transport goods, and sometimes also refers to cars that can tow other vehicles. They belong to the category of commercial vehicles. Generally, they can be divided into heavy and light according to the weight of the vehicle. Most trucks use diesel engines as their power source, but some light trucks use gasoline, LPG or natural gas.

[0003] However, there are many kinds of parts used in the production of trucks, such as steering knuckles, steering gears, steering columns, steering wheels, steering tie rods; bumpers, doors, fenders, body frame columns, etc. In particular, body frame columns also include frame crossbeams, frame cantilever beams, frame longitudinal beams, etc., which often need to be drilled at the upper and lower ends or the hole slots of the parts with upper and lower holes drilled need to be assembled and assembled during production and processing;

[0004] When processing upper and lower holes on truck parts, it is often necessary to position the parts to avoid tipping over during inspection. Different models of truck parts have different shapes and sizes, but the existing fixtures cannot adaptively meet the positioning needs of various models of truck parts, which brings inconvenience to the upper and lower hole processing operations.

[0030] The truck parts are placed on the placement seat 7, and the driving assembly is started to rotate the rotating clamping assembly so that the clamping assembly abuts against the side tangent point of the truck parts, thereby achieving the fixation of the truck parts.

[0031] In this embodiment, preferably, the rotating clamping assembly includes a hinge 4, the hinge 4 is rotatably connected to the base 1, a rotating plate 5 is fixedly connected to the hinge 4, a clamping plate 6 is fixedly connected to the top of the rotating plate 5, and the driving assembly is used to drive the rotating plate 5 to rotate. The driving assembly is started to rotate the rotating plate 5, so that the clamping plate 6 fixedly connected to the top of the rotating plate 5 abuts against the side tangent point of the truck component, thereby achieving the fixation of the truck component.

[0032] In this embodiment, preferably, a slider is provided at the bottom of the rotating plate 5, and a slide groove 9 is provided on the base 1, and the slider is arranged in the slide groove 9. When the rotating plate 5 rotates, the slider slides in the slide groove 9, follows the rotation direction thereof, and limits the rotation direction of the rotating plate 5;

[0033] In this embodiment, preferably, a plurality of balls 10 are evenly arranged on the inner walls of both sides of the slide groove 9, and the balls 10 are rotatably connected to the inner wall of the slide groove 9. The arrangement of the balls 10 reduces the friction resistance between the rotating plate 5 and the base 1 when the rotating plate 5 rotates, so that the slider slides more smoothly in the slide groove 9.

[0034] In this embodiment, preferably, the driving assembly includes a rack 11 and a gear 12. The gear 12 is rotatably arranged in the installation cavity. Two racks 11 are arranged opposite to each other, and both racks 11 are meshed with the gear 12. The end of the rack 11 is fixedly connected to the rotating plate 5.
