[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a multi - vehicle - type welding production line, including two sets of lifting mechanisms 1 for conveying vehicle parts and multiple sets of transportation and positioning groups 2. The two sets of lifting mechanisms 1 are respectively arranged at the input end and the output end of the multiple sets of transportation and positioning groups 2. The lifting mechanism 1 includes a fixed frame 3 and a movable frame 4. The movable frame 4 is vertically slidably connected in the fixed frame 3. Each of the multiple sets of transportation and positioning groups 2 is provided with two sets of transportation mechanisms. The transportation mechanism includes a fixed base 7, a limiting mechanism 8, a guiding component 9, and a moving mechanism 10. The vehicle parts are conveyed by the transportation and positioning groups 2 for welding work.

[0023] Please refer to Figure 2 , the fixed frame 3 includes a bottom frame and a vertical frame. The movable frame 4 is slidably connected up and down with the vertical frame. A lifting motor 5 is arranged on the vertical frame. A lifting belt is arranged on the vertical frame and connected with the movable frame 4.

[0028] Working principle: During use, the worker places the vehicle part and the mounting plate for fixing the vehicle part on the movable frame 4 at the loading station. The lifting motor 5 is used to drive the lifting belt to rotate. One end of the lifting belt is connected to the movable frame 4, so as to lift the movable frame 4 to the same height as the welding station above the transportation and positioning group 2. Then, the cylinder of the guiding mechanism 6 is used to push the pushing block to move. The pushing block pushes the mounting plate and the vehicle part onto the guiding component 9 of the transportation and positioning group 2. Then, the driving motor of the moving mechanism 10 is used to drive the driving guide wheel to rotate, move the mounting plate to the welding station, and use the limiting mechanism 8 to fix the workpiece. The cylinder is used to drive the limiting clamping arm to approach the mounting plate and clamp and fix the mounting plate, so as to fix the vehicle part. Then, the welding robot is used to weld the vehicle part. The transportation and positioning groups 2 at different positions can weld different vehicle parts. The welded vehicle parts can be lowered and stored at the unloading station through another set of lifting mechanisms 1, so that the loading work and the unloading work will not interfere with each other, improving the welding efficiency.
