Description

Technical Field

[0001] The utility model relates to the technical field of armrest assembly processing, and particularly relates to a welding auxiliary device for an armrest assembly. Background Technique

[0002] During the production of the armrest assembly, the skeleton thereof needs to be welded. Among them, during the processing of the right-angle structure and the vertical welding of a skeleton above the right-angle structure, manual lapping is often used for welding. This method has great problems. One is that manual lapping cannot ensure that the entire lapping surface can be closely attached, and there is a risk of virtual lapping. Once welding is carried out under the condition of virtual lapping, it is very easy to cause welding failure; the other is that the welding position accuracy of manual lapping is uncontrollable. During the welding process, the human hand often moves inadvertently. Once it moves, it will cause the welding position to be inaccurate. Therefore, it is particularly important to design a welding auxiliary device for the armrest assembly to solve the above problems. Summary of the Invention

[0003] The utility model designs a welding auxiliary device for an armrest assembly to solve the above problems. The first square skeleton and the second square skeleton can be pressed and attached together by a pressing block, and then welded directly. By this method, not only the accuracy of the welding position can be ensured, but also the occurrence of welding failure caused by virtual lapping can be effectively avoided, which plays a role in increasing the practical performance.

[0004] To solve the above technical problems, the utility model provides a welding auxiliary device for an armrest assembly, which is characterized in that: it includes a bottom plate, a first side plate, a second side plate, a first limiting block, a second limiting block, a connecting seat, a pressing block and a first screw rod. The bottom plate is in a "C" shape, and its two ends are respectively integrally connected with the vertically arranged first side plate and the second side plate. One end of the first side plate is integrally connected with one end of the second side plate at a right angle. The first limiting block and the second limiting block integrally connected with the bottom plate are respectively arranged at both ends of the bottom plate. The first limiting block faces the first side plate and forms a first limiting groove for limiting the first square skeleton between them. The second limiting block faces the second side plate and forms a second limiting groove for limiting the second square skeleton between them. The connecting seat is arranged on the top of the bottom plate and is integrally connected with it. A first threaded through hole matching the first screw rod is opened on the connecting seat. The first screw rod is horizontally arranged. One end of it passes through the connecting seat along the first threaded through hole and is connected with the pressing block. One end of the first screw rod passing through the connecting seat is rotatably connected with the pressing block. A first knob is installed at the other end of the first screw rod. The first square skeleton and the second square skeleton are respectively pressed against the first side plate and the second side plate by the pressing block.

[0005] Further: A support seat is provided on the side of the second side plate away from the second limit block.

A first top bolt is connected in the third threaded through hole. One end of the first top bolt passes through the third threaded through hole and extends into the chute to contact the trapezoidal slide rail. The support seat is locked on the trapezoidal slide rail by the friction force between the first top bolt and the trapezoidal slide rail.

[0007] Furthermore: The bent connecting column is detachably connected to the connecting cylinder. One end of the bent connecting column extends into one end of the connecting cylinder. A fourth threaded through hole is provided on the outer wall of the connecting cylinder at the connecting end with the bent connecting column.
