[0024] Specifically, the pressure testing device, through the cooperation of the movable support block 8 and the movable lead screw seat 12, can adjust the position of the pressure block 16 according to the pressure position of the automotive parts, thereby improving the practicality of the pressure testing device.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a pressure resistance testing device for stamped automotive parts. Four limiting posts 19 are fixedly installed inside the testing seat 1. A connecting plate 17 is slidably connected to the surface of the four limiting posts 19.

The telescopic end of the second electric push rod 18 is fixedly connected to the center of the bottom of the connecting plate 17.

[0026] Specifically, the limiting post 19 is used to limit and guide the connecting plate 17.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a pressure resistance testing device for stamped automotive parts. Fixing blocks 4 are fixedly installed at both corners of the testing seat 1. A first trapezoidal screw 5 is rotatably connected between the two aligned fixing blocks 4. The first trapezoidal screw 5 is threadedly connected to the bottom of the support block 8. A transmission component is provided between the two first trapezoidal screws 5.

[0028] Limiting grooves 6 are provided in the middle of both sides of the detection seat 1. Limiting sliders 7 are slidably connected inside the two limiting grooves 6. The front of the two limiting sliders 7 is fixedly connected to the side of the support block 8.

[0029] The transmission assembly includes a fixed box 9. The fixed box 9 is fixedly installed on the top of the back of the detection seat 1. Two connecting shafts 23 are rotatably connected to one side wall of the fixed box 9. One end of the two connecting shafts 23 passes through the fixed box 9 and is fixedly connected to one end of the corresponding first trapezoidal lead screw 5. The other end of the two connecting shafts 23 is fixedly installed with a second bevel gear 21. Rotating shafts 22 are rotatably connected to both sides of the inner wall of the fixed box 9. First bevel gears 20 are fixedly installed at both ends of the rotating shafts 22. The first bevel gears 20 mesh with the corresponding second bevel gears 21.

[0030] A driven gear 25 is fixedly installed in the middle of the rotating shaft 22. A first servo motor 24 is fixedly installed inside the fixed box 9. A driving gear 26 is fixedly installed on the output shaft of the first servo motor 24. The driving gear 26 and the driven gear 25 are meshed and connected.

[0031] Specifically, the rotation of the rotating shaft 22 is driven by the cooperation of the first servo motor 24, the driving gear 26 and the driven gear 25. The rotation of the rotating shaft 22 and the two first trapezoidal lead screws 5 is driven by the cooperation of the first bevel gear 20, the second bevel gear 21 and the connecting shaft 23. The synchronous rotation of the first trapezoidal lead screws 5 drives the movement of the support block 8. The movement of the support block 8 drives the movement of the fixed frame 10. The movement of the fixed frame 10 drives the movement of the pressure block 16, thereby realizing the adjustment of the position of the pressure block 16.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a pressure resistance testing device for stamped automotive parts. Limiting rods 13 are fixedly installed on both sides of the inner wall of the fixed frame 10. The two limiting rods 13 are inserted and connected to both sides of the lead screw seat 12.

The second trapezoidal lead screw 14 is threadedly connected to the lead screw seat 12. A second servo motor 11 is fixedly installed on one side of the fixed frame 10. The output shaft of the second servo motor 11 is fixedly connected to one end of the second trapezoidal lead screw 14.

[0033] Specifically, the second servo motor 11 drives the second trapezoidal lead screw 14 to rotate, the rotation of the second trapezoidal lead screw 14 drives the lead screw seat 12 to move, and the movement of the lead screw seat 12 drives the movement of the pressure block 16, thereby realizing the adjustment of the position of the pressure block 16.

[0034] In specific implementation, when using the pressure resistance testing device, first turn on the power and open the second electric push rod 18. The second electric push rod 18 pushes the connecting plate 17 to move upward. The upward movement of the connecting plate 17 causes the L-shaped pressure plate 3 to move upward, so that the L-shaped pressure plate 3 separates from the testing table 2. Then, place the automotive parts to be tested on the top of the testing table 2. Then, close the second electric push rod 18. The second electric push rod 18 retracts and causes the connecting plate 17 to move downward. The downward movement of the connecting plate 17 causes the L-shaped pressure plate 3 to move downward, which facilitates the limiting and fixing of the edge of the car.

[0035] Next, the position of the pressure block 16 is adjusted according to the pressure test position. First, the second servo motor 11 is turned on, which drives the drive gear 26 to rotate. The drive gear 26 meshes with the driven gear 25, thereby driving the rotating shaft 22 to rotate. The rotating shaft 22 and the first trapezoidal lead screw 5 are connected by the first bevel gear 20, the second bevel gear 21 and the connecting shaft 23 to drive the two first trapezoidal lead screws 5 to rotate synchronously. The rotation of the first trapezoidal lead screw 5 drives the support block 8 to move. The movement of the support block 8 drives the fixed frame 10 to move. The second servo motor 11 drives the second trapezoidal lead screw 14 to rotate. The second trapezoidal lead screw 14 drives the lead screw seat 12 to move. The movement of the lead screw seat 12 drives the pressure block 16 to move, so that the pressure block 16 moves to the pressure test position. Then, the first electric push rod 15 is turned on, which pushes the pressure block 16 to move down. During the downward movement of the pressure block 16, the pressure is detected in real time by the pressure sensor to realize the pressure test of the automotive parts.
