Abstract

The invention discloses a doorsill type workpiece welding fixture. The doorsill type workpiece welding fixture comprises a base, a first rotating arm and a second rotating arm, wherein a first pressing head is fixed to the base; the first rotating arm is pivoted to the base, and a first support block, a second support block and a third support block are fixed to the inner side of the first rotating arm in sequence from bottom to top; and the second rotating arm is pivoted to one end, which is far from the base, of the first rotating arm, and a second pressing head, a third pressing head, a fourth pressing head and a fifth pressing head are fixed to the inner side of the second rotating arm. Compared with the prior art, the doorsill type workpiece welding fixture has the advantages that five pressing points are set, wherein three pressing points act on a doorsill, two pressing points act on a floor assembly, and a plurality of pressing points are realized on the welding fixture, so that the doorsill can be effectively fixed, additionally, the floor assembly is assisted to be pressed, the welding stability of the whole assembly is increased, the structure of the welding fixture is simple, and the welding space is enough, so that the welding operation difficulty of employees is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a threshold-type workpiece welding fixture. Background technique [0002] Welding fixtures are an important means to ensure the accuracy of auto parts, and reasonable positioning and pressing forms are the key to fixture design. In the automobile body sub-assembly parts, the combination of threshold and floor assembly is an important part of body welding. The position accuracy of the threshold directly affects the accuracy of the final combination of the side wall and the lower body. The threshold combining station is the body in white The key station that needs to be controlled for precision improvement. [0003] Such as figure 1 The schematic diagram of the assembly state of the fixture in the prior art is shown. The existing fixture generally presses the flange edge of one side of the threshold 01, and the compression stability is weak. At the same time, it has...
