Heavy Duty Rim Welding Fixtures

Abstract

The invention discloses a heavy wheel rim welding clamp. The heavy wheel rim welding clamp comprises a base and a supporting disc installed on the base, wherein a vertically-arranged lifting oil cylinder is arranged on the base, a tip cone is installed at the top end of a telescopic rod of the lifting oil cylinder, radially distributed guide grooves are formed in the outer conical surface of the tip cone, a rolling wheel is pressed in each guide groove, each rolling wheel is installed on radially distributed guide rods respectively, the guide rods can radially telescope through a guide sleeve installed on the supporting disc, supporting claws are installed at the tail ends of the guide rods, and the outer side end faces of the supporting claws are provided with supporting faces. After the structure is adopted, three sections of a wheel rim cylinder are kept coaxial during butt welding, the concentricity during welding is ensured, the running balance performance of a vehicle is effectively improved, dynamic load impact is reduced, and the service life is prolonged. The heavy wheel rim welding clamp facilitates welding and enables the welding precision to be high, meanwhile turning machining is needed no longer after the butt welding is completed, production processes are optimized, the machining efficiency is improved, and accordingly the machining cost is reduced.

Description

technical field [0001] The invention relates to an auxiliary tool for welding automobile parts, in particular to a heavy-duty wheel rim welding fixture. Background technique [0002] The main body of the rim is a cylindrical workpiece. The main body of the rim is composed of three structural parts in the axial direction. For the main body of the rim, it is usually necessary to splice the three structural parts by welding and then weld them into one body. However, in the process of splicing and welding, traditionally, manual positioning is generally used, which brings problems such as poor positioning accuracy. During the welding process, the roundness of the rim cannot be guaranteed, and then it needs to be processed on a lathe to ensure the dimensional accuracy. This processing method is labor-intensive and time-consuming, and the accuracy of the concentricity of the manufactured rim body is poor.
