Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts manufacturing process, in particular to a welding tool for an automobile sliding door hinge wire bracket. Background Art
[0002] Automotive sliding door systems are increasingly popular with customers due to their unique opening method, offering numerous advantages over traditional hinged revolving doors, such as reduced opening space requirements, easy access, convenient loading and unloading, and the ability to operate them electrically. Sliding door systems are driven by either manual or electric drive, with electric drive being the predominant method in mid- to high-end MPVs. The drive cable is connected to the center hinge using a plastic clip. The precision of the fit between the cable bracket and the center hinge directly impacts the installation quality of the clip, thus affecting the proper opening and closing of the door. Therefore, the relative positional accuracy of the center hinge cable bracket and the mandrel is crucial. Due to the cable bracket's spatial structure, welding the cable bracket to the mandrel can only be performed using manual argon arc welding. Due to the clearance, the relative position of the cable bracket and the pin is difficult to maintain, resulting in low welding efficiency and significant welding difficulty. Utility Model Content
[0003] In order to overcome the disadvantage of the prior art that it is difficult to manually determine the relative position of the wire bracket and the pin shaft, one of the purposes of the utility model is to provide a welding tool for the wire bracket of the hinge of an automobile sliding door.

[0005] The positioning structure includes a positioning fixing block, which is fixedly connected to the upper side of the turntable. A circular groove is formed on the upper side of the positioning fixing block. A supporting block and a second blocking block are fixedly connected to the upper side of the positioning fixing block. There are two supporting blocks and four blocking blocks. A spring and a cylindrical block are arranged inside the circular groove to facilitate the fixing of the wire bracket.
[0006] According to the welding fixture for a sliding door hinge cable bracket for an automobile, the rotating structure includes a rotating shaft that is rotatably connected to the upper side of the base, and a turntable fixedly connected to the other end of the rotating shaft. This facilitates the rotation of the welding mechanism to weld the cable bracket and the shaft core block.
[0007] According to the welding fixture for the automobile sliding door hinge cable bracket, the outer side of the turntable is fixedly connected to a limit block to prevent the turntable from rotating too much and causing uneven welding.
[0008] According to the welding fixture for a hinge cable bracket for an automobile sliding door, the clamp structure includes a clamp fixing block, which is fixedly connected to the upper side of a turntable. Bracket block 1 is fixedly connected to the upper side of the clamp fixing block. A rotating rod is rotatably connected to the inner side of bracket block 1. A movable hole is provided on the outer side of the rotating rod. Bracket block 2 is fixedly connected to the outer side of bracket block 1. Bracket block 2 is rotatably connected to the inner side of bracket block 2. Sliding blocks are slidably connected to the upper and lower sides of the rotating rod. A threaded block is provided on the outer side of the sliding block. Threaded clamp blocks are provided inside the threaded block and the movable hole. This facilitates the fixation of the cable bracket and the shaft core block.
[0009] According to the welding fixture for the automobile sliding door hinge cable bracket, the rotating block is arranged outside the rotating rod to facilitate limiting the rotation of the rotating rod.
[0010] According to the welding fixture for the automobile sliding door hinge cable bracket, one end of the spring is fixedly connected to the positioning block, the other end of the spring is fixedly connected to the cylindrical block, and the cylindrical block and the positioning block are slidably connected, which facilitates the placement of the shaft core block by the operator.
[0011] The above scheme has the beneficial effects: through the setting of the rotating structure, the clamping structure and the positioning structure, when the wire drawing bracket equipped with the shaft core block is placed on the positioning structure, the threaded clamp block presses the shaft core block so that the flange surface of the shaft core block fits with the installation surface of the wire drawing bracket, and then manual argon arc welding is used for welding. During welding, the rotating structure can be rotated to weld the entire weld, reducing the difficulty of operation for workers. The device structure is simple and easy to operate.
