Description
Technical Field
[0001] The utility model relates to the technical field of rear seat armrest skeleton processing, and particularly relates to a fixing fixture for welding a rear seat armrest skeleton. Background Technique
[0002] As Figure 1 shown, the vehicle rear seat armrest skeleton is composed of a skeleton main body 18, a limiting shaft 19 and a rotating shaft 20. The limiting shaft and the rotating shaft are both fixed to the skeleton main body by welding. After the rotating shaft is welded, people need to flip the skeleton main body to weld the limiting shaft on its other surface. However, in the actual operation process, since the flipped skeleton main body cannot be placed flat after the rotating shaft is fixed, it is very easy for the skeleton main body to move due to vibration or other external forces when welding the limiting shaft. Once the skeleton main body moves during welding, it is very easy to cause the failure of welding. Moreover, when welding the rear seat armrest skeleton, for the convenience of operation, the limiting shaft and the rotating shaft are often placed together. In the actual welding process, problems such as welding them in the reverse way, welding two limiting shafts or two rotating shafts on the same skeleton main body are likely to occur. Therefore, it is particularly important to design a fixing fixture for welding a rear seat armrest skeleton to solve this problem. Summary of the Invention
[0003] The utility model designs a fixing fixture for welding a rear seat armrest skeleton to solve the above problems. By setting the fixture assembly and the rotation locking mechanism, it can effectively prevent the unnecessary movement of the skeleton main body during forward and reverse welding, enabling the welding work to proceed smoothly and reducing the risk of welding failure.

Before work, the rotating shaft and the limiting shaft to be welded are uniformly placed on the left and right sides of the fixed base plate, and then the skeleton body to be welded is fixed by the clamp assembly. The rotating shaft or the limiting shaft on the corresponding side is placed according to the orientation of the welding position on the skeleton body. After the rotating shaft or the limiting shaft is placed in the welding position, it is welded and fixed by a welding machine. After the rotating shaft or the limiting shaft on this side is welded, the rotating shaft is rotated to flip the skeleton body, and then the rotating shaft or the limiting shaft on this side is placed to continue welding. The utility model can effectively prevent the skeleton body from unnecessary movement during forward and reverse welding by providing a clamp assembly and a rotation locking mechanism, so that the welding work can proceed smoothly and the risk of welding failure is reduced.

The tooth structure on the locking block is connected to the gear under the action of the spring. The shifting block is arranged on the outer wall of the locking block and is connected to the gear. When the rotating shaft needs to be rotated, the shifting block is shifted to separate the locking block from the gear. At this time, the rotating shaft is rotated. After the rotation is in place, the shifting block is released to lock the gear using the locking block.
[0020] like Figure 3The shown fixture assembly includes an L-shaped support plate 14, an L-shaped clamping plate 15 and a clamping electric cylinder 16.

The upper end of the second through groove is open and communicates with the guiding groove. A connecting seat is fixed at each of the left and right ends of the lifting seat. The connecting seat extends out of the support seat along the second through groove and can slide up and down along the second through groove. A telescopic electric cylinder 5 is installed on the connecting seat extending out of the support seat. The output shaft end of the telescopic electric cylinder is connected to a mounting block 6 through a connecting member. A lifting electric cylinder 7 is installed on the top of the mounting block.
