[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] according to Figure 1-4 As shown: This utility model provides a stamping positioning device for automotive stamping parts: including a bracket 4, a lower die body 1, and an upper die body 2; the lower die body 1 is disposed in the bracket 4, and a groove 5 is provided in the lower die body 1; the upper die body 2 is slidably connected to the bracket 4, and a protrusion 6 corresponding to the groove 5 is fixedly connected to the lower part of the upper die body 2; a hydraulic press 3 is disposed on the bracket 4, and the upper die body 2 is fixedly connected to the working end of the hydraulic press 3.
[0022] like Figure 1 , 2 As shown, there are two positioning rods 7, and one clamping rod 8 that can form a triangle with the two positioning rods 7; through three-point positioning, the positioning of the circular stamping part can be quickly achieved; the positioning rods 7 are slidably mounted on the lower die body 1, and an adjustment groove 10 is provided in the lower die body 1, and an adjustment component that can drive the two positioning rods 7 to slide simultaneously is provided in the adjustment groove 10.
[0023] like Figure 3 As shown, the adjustment assembly includes a motor 9, a bidirectional lead screw 12, and adjustment blocks 11. The motor 9 is located on the side wall of the lower die body 1. The bidirectional lead screw 12 is rotatably mounted in the adjustment groove 10 and is fixedly connected to the output shaft of the motor 9. Two adjustment blocks 11 are provided, and the two adjustment blocks 11 are threadedly connected to corresponding positions of the bidirectional lead screw 12. A first guide groove 13 communicating with the adjustment groove 10 is provided on the lower die body 1, and the adjustment blocks 11 pass through the first guide groove 13 and are fixedly connected to the positioning rods 7. By setting the motor 9 and the bidirectional lead screw 12, the two positioning rods 7 can be easily adjusted to accommodate circular stamping parts of different diameters.
[0024] like Figure 4 As shown, the clamping rod 8 is slidably mounted on the lower mold body 1. A groove 15 is provided inside the lower mold body 1, and a sliding component capable of driving the clamping rod 8 to slide is provided inside the groove 15.
[0025] The sliding assembly includes an electric telescopic rod 14 and a slider 16. The electric telescopic rod 14 is mounted on the lower mold body 1, and the slider 16 is slidably disposed within a groove 15, with the slider 16 fixedly connected to the working end of the electric telescopic rod 14.

[0026] The principle of this utility model
[0027] like Figure 1 , 2 As shown, when using this application, the circular stamped part is placed on the lower die body 1, so that the circular stamped part simultaneously contacts the two positioning rods 7, completing the initial positioning of the stamped part; then the electric telescopic rod 14 is activated, driving the clamping rod 8 to move towards the circular stamped part until the clamping rod 8 contacts the circular stamped part, at which point the final positioning and fixing of the circular stamped part is completed. The whole process is quick and convenient, and the two positioning rods 7 and one clamping rod 8 can achieve precise positioning of the stamped part, making the center of the stamped part correspond to the center of the groove 5. The structure is simple and the positioning efficiency is high.
