[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 7 , the laser welding positioning tooling at the taillight includes a base plate 1, on which a welding support mechanism and a welding clamping mechanism are provided, and the welding support mechanism and the welding clamping mechanism are arranged oppositely;

[0024] The welding support mechanism includes a flip support mechanism installed on the top of the base plate 1 and a horizontal support mechanism provided on one side of the flip support mechanism, for supporting the side of the workpiece;

[0025] The welding clamping mechanism includes a flip clamping mechanism arranged on the top of the base plate 1 and a horizontal clamping mechanism arranged on one side of the flip clamping mechanism, which is used to apply pressure to the supporting surface of the workpiece.

[0026] When the device is in use, the workpiece is the automobile taillight installation assembly, which consists of three parts. Figure 1 A, B and C are used to represent them respectively. First, part A is placed (other tooling is required to support part A. This tooling is a welding tooling, so the support tooling for part A is not shown in the figure). Then the flip support mechanism and the horizontal support mechanism are controlled in place. Next, parts B and C are placed on the flip support mechanism and the horizontal support mechanism. Finally, the flip clamping mechanism and the horizontal clamping mechanism provided on one side of the flip clamping mechanism are used to complete the clamping process. At this time, the welding operation can be started. Compared with the existing technology, this device has redesigned the welding tooling for the automobile rear taillight installation assembly. The overall structure of the tooling is compact, which can fully support and clamp the weld, thereby reducing the welding deformation and improving the welding quality.

[0027] In this embodiment, the bottom plate 1 is further provided with a plurality of bottom clamping mechanisms for applying force to the bottom of the workpiece.

[0028] In this embodiment, the flip support mechanism and the flip clamping mechanism both include a first cylinder 2, a mounting base 3 arranged on one side of the first cylinder 2, a second cylinder 4 rotatably mounted on the mounting base 3 through a rotating shaft, and a connecting member 5 rotatably mounted on the driving end of the first cylinder 2. The connecting member 5 is rotatably connected to the second cylinder 4. The tops of the two second cylinders 4 are respectively provided with a first support member 7 and a first clamping member 8. The flip support mechanism and the flip clamping mechanism are used to fix part B.

[0029] In this embodiment, the horizontal support mechanism includes a horizontal slide 6 and a second support member 11 arranged at the driving end of the horizontal slide 6. The horizontal clamping mechanism includes a horizontal slide 6 and a second clamping member 12 arranged at the driving end of the horizontal slide 6. The second support member 11 is adapted to the second clamping member 12. Both horizontal slides 6 are electric slides. The positions of the two horizontal slides 6 are set vertically at 90 degrees. The horizontal support mechanism and the horizontal clamping mechanism are used to fix part C.

[0031] In this embodiment, the first pressing member 8, the first supporting member 7, the second pressing member 12, the second supporting member 11 and the bottom supporting member 10 are all composed of a plurality of L-shaped parts, and the plurality of parts are connected to each other by a rotating shaft. A rubber buffer pad is provided between the parts used to press or support the workpiece and the adjacent parts to adapt to the shape of the workpiece and avoid damage to the workpiece due to excessive rigidity during the pressing process. The parts are connected by the rotating shaft to facilitate adjustment of the direction and angle of the parts, and are suitable for workpieces of different shapes, such as Figure 6 shown.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
