Description

Technical Field

[0001] The utility model relates to the technical field of truck wheel hub processing, and more specifically, to a special clamp for a heavy truck wheel hub. Background Art

[0002] The wheel hub is a cylindrical metal part with the inner profile of the tire supporting the tire, and the center is installed on the axle. It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheels according to their diameter, width, molding method, and material. The truck wheel hub is an important part of the truck tire, used to support the tire and bear the weight of the vehicle and various forces during driving.

[0003] During the brake drum production process, the inner and outer surfaces of the brake drum need to be cleaned and painted. The current cleaning method is fixed clamping and cleaning with a fixed high-pressure water gun head, but there are some dead corners that cannot be completely cleaned, and the cleaning efficiency is low. During the cleaning process, the brake drum needs to be rotated and clamped stably, and the existing clamping tools cannot meet production needs.

[0004] After searching, the Chinese patent with application number CN202120270050.7 discloses a wheel hub clamp, in which the wheel hub presses the part of the L-shaped clamp connected to the connecting rod, so that the L-shaped clamp rotates around the hinge with the circular rotating bracket, so that the clamping pulley presses the wheel hub, and at the same time the connecting rod drives the sliding block to compress the reset spring. At the same time, the connecting rod and the L-shaped clamp play a supporting role. When rotation is required, a spray nozzle is used to spray the paddle, so that rotation cleaning can be carried out, which is convenient for cleaning and can meet the requirements of both tightening and rotation. At the same time, it can also clamp wheels of different diameters.

[0005] When the above-mentioned wheel hub clamp is actually used, the existing wheel hub clamp is not convenient for turning over the wheel hub, resulting in that during the wheel hub production process, the operator needs to use tools to turn over the wheel hub, thereby reducing the production efficiency of the wheel hub.

[0013] As a further description of the above technical solution: a support frame is fixedly connected to one side of the connecting frame, and a plurality of connecting holes are provided on both sides of the support frame.
