Description

Clamp capable of clamping various rim specifications Technical Field The utility model relates to the technical field of rim clamps, in particular to a clamp capable of clamping various rim specifications. Background The steel wire wheel is also called a spoked wheel, and comprises spokes, a hub and a rim, so that the steel wire wheel has good elasticity, can absorb road surface impact, is suitable for non-paved road surfaces, and is generally used for wheels of off-road motorcycles. The rim of the motorcycle is a core component of the wheel of the motorcycle and mainly bears the functions of supporting the tire, transmitting power, buffering vibration and the like. The material is mostly aluminum alloy or steel section bar, and is formed by the processes of rolling, cutting, shaping, butt welding, polishing, punching and the like, and has the characteristics of light weight, high strength and the like. In the manufacturing process, the dimensional accuracy and static and dynamic balance quantity performance are required to be ensured, and the running safety and the control stability of the vehicle are directly affected. In the rim production process, a jig for clamping the rim is an important medium for connecting the processing equipment with the workpiece. The universality of the clamp is important to the improvement of the production efficiency. Taking the forming machine and the blanking machine as examples, the universal clamp can adapt to clamping requirements of rims of different types, and the processing of multi-specification products can be completed without frequently replacing the clamp. The compatibility not only reduces the equipment debugging time, but also reduces the cost of purchasing the special fixture for enterprises. Meanwhile, the universal fixture can simplify the production management flow, reduce the downtime caused by fixture switching and ensure the continuous operation of the production line. Flexibility of the universal fixture is particularly important for manufacturing enterprises. The clamp can quickly respond to market demand change, and clamp abandonment caused by product iteration is avoided.
