Abstract

The invention relates to the field of automobile manufacturing devices, in particular to a car lock lug welding fixture. By the car lock lug welding fixture, the problem that an existing lock lug welding fixture is insufficient of space for arrangement is solved. A plurality of positioning seats (4) are arranged on a rectangular welding fixture platform (1), a lug clamping unit is arranged on each positioning seat (4), each lug clamping unit comprises a lug clamping cylinder (5), a lug positioning cylinder (6) and a wedge mechanism (7), each lug positioning cylinder (6) is connected with the corresponding wedge mechanism (7) and drives the same to move horizontally, and wedges (18) can be driven to move by being connected with the corresponding lug clamping cylinders (5). The car lock lug welding fixture is used for welding automotive lugs.

Description

technical field [0001] The invention relates to the field of automobile manufacturing devices, in particular to an automobile lock lug welding fixture. Background technique [0002] At present, domestic automobile manufacturing companies generally use profile positioning for the positioning of the top cover outer plate on the welding line. Due to the extremely small size of the locking lugs, which are stamped and formed from thin steel plates, and the actual welding electrode position is just above the bottom surface of the lugs, there is not enough space for the positioning design of the lug welding jig. Contents of the invention [0003] The object of the present invention is to provide an automobile lock lug welding jig to solve the problem that the current lock lug welding jig does not have enough space for arrangement. [0004] The technical scheme adopted by the present invention to solve the above technical problems is: the clamp includes a rectangular welding fixt...
