[0021] Embodiment 1: Please refer to Figures 1-4 , a fixture for processing automotive shock absorber supporting stamping parts with strong adaptability, including a fixture seat 4 and a hollow cavity 15. A hollow cavity 15 is provided inside the fixture seat 4. An installation cavity 19 is provided at the middle position of the top of the fixture seat 4. Moving grooves 3 are provided on both sides of the installation cavity 19. Clamping blocks 2 are embedded inside the moving grooves 3.

A clamping piece 18 is fixedly connected to the end face of the locking screw 17. There are two groups of clamping pieces 18 and they are symmetrically distributed in the vertical direction;

[0023] Specifically, as shown in Figure 1 and Figure 3 , when the two groups of clamping blocks 2 move relative to each other, the workpiece can be clamped. During clamping, the clamping piece 18 tightly abuts against the workpiece. For workpieces with different shapes, clamping pieces 18 with different shapes can be used. Just disassemble the locking screw 17, and the fixing rod 21 can be removed together with the clamping piece 18 and a new clamping piece 18 can be replaced, so as to adapt to the workpiece, and the applicability is relatively strong.

[0024] Embodiment 2: A positioning die 1 is provided inside the installation cavity 19. Fixing bolts 16 are fixedly connected between the four sides of the positioning die 1 and the fixture seat 4 respectively. A cavity 22 is provided at the top of the positioning die 1;

[0025] Specifically, as shown in Figure 1 and Figure 4As shown in the figure, under the impact of long-term stamping processing, the positioning die 1 of the fixture will also be deformed. The positioning die 1 of this fixture can be removed from the installation cavity 19, and a new positioning die 1 can be replaced, changing the integrally formed structure, with strong maintainability and no need for overall maintenance. According to different workpiece specifications, cavities 22 of different sizes are designed for processing.

[0026] Embodiment 3: A rotating piece 9 is arranged inside the hollow cavity 15. A connecting shaft 12 is movably connected between the top end of the rotating piece 9 and the top end inner wall of the hollow cavity 15. A driving motor 11 is arranged at the bottom end of the hollow cavity 15. The output end of the driving motor 11 is fixedly connected with a driving shaft 10. The top end of the driving shaft 10 is fixedly connected with the rotating piece 9. Limiting grooves 8 are arranged on both sides of the driving motor 11. The bottom ends of the clamping blocks 2 are respectively fixedly connected with pull rods 5. The bottom ends of the pull rods 5 are respectively provided with first hinge blocks 6. Second hinge blocks 13 are arranged on both sides of the rotating piece 9. A connecting handle 14 is movably sleeved between the first hinge block 6 and the second hinge block 13. The rotating piece 9 is diamond-shaped. Two groups of connecting handles 14 are arranged and kept parallel. The bottom ends of the second hinge blocks 13 are respectively movably sleeved with limiting rods 7. The limiting rods 7 are respectively embedded and move inside the limiting grooves 8.

[0027] Specifically, as Figure 1 and Figure 2 shown, the workpiece is inserted into the cavity 22 of the positioning die 1. The driving motor 11 is started. The driving shaft 10 of the driving motor 11 drives the rotating piece 9 to rotate. When the rotating piece 9 rotates clockwise, the pull rods 5 pull the two clamping blocks 2 to move relatively in the moving grooves 3, so as to quickly clamp the workpiece. The limiting rods 7 are embedded and move in the limiting grooves 8 to ensure the horizontal movement of the clamping blocks 2. Similarly, when the rotating piece 9 rotates in the reverse direction, the clamping blocks 2 are loosened, realizing an automatic and quick precise clamping effect.

[0028] Working principle: When the utility model is in use, first, the workpiece is inserted into the cavity 22 of the positioning die 1. The driving motor 11 is started. The driving shaft 10 of the driving motor 11 drives the rotating piece 9 to rotate. When the rotating piece 9 rotates clockwise, the pull rods 5 pull the two clamping blocks 2 to move relatively in the moving grooves 3, so as to quickly clamp the workpiece. The limiting rods 7 are embedded and move in the limiting grooves 8 to ensure the horizontal movement of the clamping blocks 2. After the stamping processing is completed, the rotating piece 9 rotates in the reverse direction, the clamping blocks 2 are loosened, and the workpiece can be taken out. The positioning die 1 of this fixture can be removed from the installation cavity 19, and a new positioning die 1 can be replaced. The two clamping blocks 2 can clamp the workpiece when moving relatively. When clamping, the clamping piece 18 tightly abuts against the workpiece. For workpieces with different outer shapes, clamping pieces 18 of different shapes can be used. Only by disassembling the locking screw 17, the fixing rod 21 and the clamping piece 18 can be removed together and a new clamping piece 18 can be replaced.
