Welding clamp for heavy truck bumper assembly

Abstract

The invention relates to a welding clamp for a heavy truck bumper assembly. The welding clamp comprises a base, a supporting frame, a sliding rod, an adjustment threaded rod, a threaded disc, a rotating plate, a bolt and an adjusting screw. The base is fixed to the upper portion of a welding working table. A boss is connected below the base and fixed to the lateral side of the welding working table. A plurality of positioning holes are formed in the upper portion of the base. The supporting frame is arranged in the positioning hole in the left side of the base. The sliding rod capable of vertically sliding is arranged on the supporting frame, and the specific position of the sliding rod is adjusted through the adjusting screw. The adjusting threaded rod vertically penetrating the sliding rod is arranged at the other end of the sliding rod. The threaded disc is connected to the lower portion of the adjusting threaded rod. The rotating plate is arranged in the positioning hole in the right side of the base. A sliding groove is formed in the rotating plate. The bolt penetrates the sliding groove and the positioning hole below the sliding groove. The bottom end of the bolt is fixed into a threaded hole in the welding working table. A fixing hole is formed in the other end of the rotating plate. The welding clamp is simple in structure, and welding errors are reduced; and the welding clamp is suitable for welding various heavy truck bumper assemblies, light in weight and convenient to use, and has the high universality; and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a welding clamp for a heavy truck bumper assembly. Background technique [0002] Car bumpers not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact, protect the body and protect the body and occupants. The bumper welding jig is a tooling fixture used to tailor the left and right brackets and the front fender assembly of the automobile bumper. For the technical requirements of the workpiece of the bumper, the position, size and angle of the left and right brackets of the bumper relative to the front fender assembly are relatively high. The structure of the heavy-duty vehicle bumper assembly is complex, and the general welding fixture cannot meet its welding requirements. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a hea...
