[0026] Place the part blank on the stamping table 1 and adjust the position. Pull up the movable rod 7. The tail end of the movable rod 7 is rotatably connected to the front ends of the two groups of transmission plates 8, so that the front ends of the transmission plates 8 move upward following the movable rod 7. The tail ends of the transmission plates 8 are rotatably connected to the front ends of the first sliders 9. Under the linkage action of the movable rod 7 and the transmission plates 8, the tail ends of the transmission plates 8 drive the first sliders 9 to slide horizontally along the first chutes 11 and compress the springs 13, thereby disengaging the fixing pins 10 from the pin holes 4 and releasing the fixation between the movable block 5 and the guiding groove 3. At the same time, push the fixing plate 6. The fixing plate 6 is fixedly connected to the movable block 5, so that the fixing plate 6 drives the movable block 5 to slide along the track of the guiding groove 3 until one side of the fixing plate 6 abuts against the edge of the part blank. Release the movable rod 7, and the potential energy stored in the springs 13 is released, then drive the first sliders 9 and the fixing pins 10 to rebound, so that the fixing pins 10 are inserted into the pin holes 4, thereby achieving the purpose of fixing the part blank.

A connecting rod 20 is rotatably connected to the bottom of the second slider 19. The tail end of the connecting rod 20 is rotatably connected to a square block 21. The bottom of the square block 21 is fixedly connected to an electric telescopic rod 22. The tail end of the electric telescopic rod 22 is fixedly connected to a first support plate 23;

[0028] Place the part blank on the stamping table 1, control the electric telescopic rod 22 to be energized, so that its front end drives the square block 21 to move downward. The three adjacent sides of the square block 21 are respectively rotatably connected to the three connecting rods 20, so that the square block 21 drives the front ends of the connecting rods 20 to descend synchronously. The tail end of the connecting rod 20 is rotatably connected to the tail end of the second slider 19. When the square block 21 drives the front end of the connecting rod 20 to descend, the inclination angle of the connecting rod 20 changes, and then drives several second sliders 19 to slide horizontally and approach the blank along the track of the second sliding groove 17. The guiding column 18, the second slider 19 and the moving plate 15 are all fixedly connected. Under the connection and transmission of the guiding column 18, the second slider 19 drives the moving plate 15 to slide, and then several moving plates 15 respectively limit the three sides of the blank, so that the blank is in the center position. Through precise positioning, it is possible to avoid unnecessary impact and wear on the mold caused by the position deviation of the blank during the stamping process, thereby extending the service life of the stamping equipment.

[0029] Please refer to Figure 1 , a positioning mechanism for stamping automotive parts: A lower mold 24 is fixedly installed in the middle of the top of the stamping table 1. A plurality of support rods 25 are fixedly installed on the top of the stamping table 1. The top of the support rod 25 is fixedly connected to a second support plate 26. A stamping mechanism 27 is fixedly installed at the bottom of the second support plate 26;

[0030] Align the blank with the lower mold 24 and fix it, and then start the stamping mechanism 27 to complete the stamping and shaping of the blank. By vertically arranging the stamping mechanism 27 above the lower mold 24, it is ensured that the punching force acts directly and evenly on the blank, reducing the force transmission path and loss, making the stamping process more efficient and improving productivity.

[0031] Working principle: Place the blank of the component on the lower die 24 of the stamping table 1, control the electric telescopic rod 22 to be energized, and make its front end drive the square block 21 to move downward. Under the linkage action of the connecting rod 20, several groups of second sliders 19 drive the guide posts 18 and the moving plates 15 to slide close to the blank along the track of the through groove 16 until several groups of moving plates 15 are all tightly attached to the edge of the blank, thereby achieving the purpose of limiting the three sides of the blank, correcting the position of the blank, and making the blank in the centered position. Pull the movable rod 7 upward. Under the linkage action of the transmission plate 8, the fixation between the movable block 5 and the mounting plate 2 is released. At the same time, push the fixed plate 6 to make the fixed plate 6 tightly attached to the edge of the blank. Release the movable rod 7, and the potential energy stored in the spring 13 is released, and then drive the fixed pin 10 to rebound into the pin hole 4, so that the movable block 5 is fixed to the mounting plate 2, thus achieving the purpose of fixing the blank. When the size of the blank becomes larger, control the electric telescopic rod 22 to move in the reverse direction, pull the movable rod 7 to release the fixing mechanism and push the fixed plate 6 in the reverse direction, and then the blank of other sizes can be fixed again.
