[0002] A dynamic pressure simulation testing machine is a device that squeezes an object, then simulates the dynamic pressure of the object, and then completes the testing of the object.

[0003] When conducting a dynamic pressure simulation test on a rubber seal, the rubber seal is placed on the workbench, and then a button on the controller on one side is pressed to start the electric telescopic rod on the bracket, so that the pressing block on one side of the electric telescopic rod continuously squeezes the rubber seal on the workbench with different forces. Then, a sensor on one side of the workbench collects data on the rubber seal under dynamic pressure, and then completes the dynamic pressure simulation test of the rubber seal. When the rubber seal is continuously impacted by the pressing block, the rubber seal is likely to move on the workbench, which may lead to problems affecting the subsequent extrusion effect of the pressing block on the rubber seal. Summary of the Utility Model

The fixing device 2 fixes and restricts the position of the rubber seal to be detected on the surface of the workbench 1. When performing a dynamic pressure simulation test on the rubber seal, the rubber seal is placed on the workbench 1, and then the fixing device 2 is fixed to the workbench 1 through the installation component 3. Then, the fixing device 2 fixes and restricts the position of the rubber seal. Then, the button 8 on the controller 7 on one side of the workbench 1 is used to start the electric telescopic rod 5 on the bracket 4, so that the pressing block 6 on one side of the electric telescopic rod 5 continuously squeezes the rubber seal on the workbench 1 with different forces. Then, the sensor 9 on one side of the workbench 1 collects data on the rubber seal under dynamic pressure, and then completes the dynamic pressure simulation test of the rubber seal.

[0029] Refer to Figures 1-4As shown in the figure, this embodiment discloses that the fixing device 2 includes a slide rail 21. The slide rail 21 is located on one side of the workbench 1 close to the bracket 4. Two sliding blocks 22 are slidably connected inside the slide rail 21. The two sliding blocks 22 are in an L shape. On the side of the two sliding blocks 22 away from the slide rail 21, bolts 23 are threadedly inserted. On one side of the bolt 23, a fixing plate 24 is rotatably connected. On the side of the bolt 23 away from the fixing plate 24, an operation block 25 is fixedly connected. The fixing plate 24 is located on both sides of the rubber seal. When placing the rubber seal under the pressing block 6 of the workbench 1, the sliding blocks 22 inside the slide rail 21 can be moved first to make the two sliding blocks 22 reach both sides of the rubber seal. Then, the distance between the two fixing plates 24 is adjusted to fit the size of the rubber seal. Then, through the operation block 25, the bolt 23 is rotated to drive the fixing plate 24 to approach both sides of the rubber seal, and then the rubber seal is squeezed and fixed. By using the fixing device 2, the fixing plate 24 can be used to fix the position of the rubber seal, avoiding the situation that the rubber seal moves on the workbench 1 when the rubber seal is continuously impacted by the pressing block 6, so that the pressing block 6 can subsequently squeeze and test the rubber seal well, thereby improving the use effect of the dynamic pressure simulation testing machine.

The plurality of anti-slip blocks 26 are arranged equidistantly on one side of the fixing plate 24. By using the anti-slip blocks 26, the friction between the fixing plate 24 and the rubber seal is increased, thereby improving the use effect of the fixing plate 24. Arc-shaped strips 27 are fixedly connected to both sides of the sliding block 22, and the arc surfaces of the arc-shaped strips 27 are smooth. By using the arc-shaped strips 27, the friction between the sliding block 22 and the slide rail 21 is reduced, making it easier for the sliding block 22 to move inside the slide rail 21.

[0031] Refer to Figures 1-4 As shown in the figure, this embodiment discloses that a limiting component 28 is provided on one side of the sliding block 22.

Then the clamping block 32 is moved so that the clamping block 32 passes through the installation plate 31 and is fixed to the connecting plate 33. Then the baffle 34 is moved to block the position of the clamping block 32. Then the position of the slide rail 21 is fixed. By using the installation component 3, the position of the fixing device 2 can be quickly installed and fixed, which is convenient for the operator to use the fixing device 2 subsequently.

[0033] Referring to Figures 1-4 As shown in the figure, this embodiment discloses that a connecting rope 35 is fixedly connected to one side of the clamping block 32. The side of the connecting rope 35 away from the clamping block 32 is fixedly connected to the installation plate 31. By using the connecting rope 35, the clamping block 32 is connected to the installation plate 31 to prevent the loss of the clamping block 32.

[0034] Working principle: When performing a dynamic pressure simulation test on a rubber seal, the rubber seal is placed on the workbench 1. Then the slide rail 21 can be moved so that the connecting plate 33 on one side of the slide rail 21 is inserted into the installation plate 31. Then the clamping block 32 is moved so that the clamping block 32 passes through the installation plate 31 and is fixed to the connecting plate 33. Then the baffle 34 is moved to block the position of the clamping block 32. Then the position of the slide rail 21 is fixed. When the rubber seal is placed under the pressing block 6 on the workbench 1, the sliding blocks 22 inside the slide rail 21 can be moved first so that the two sliding blocks 22 reach both sides of the rubber seal. Then the distance between the two fixing plates 24 is adapted to the size of the rubber seal. Then, by operating the block 25, the bolt 23 is rotated so that the bolt 23 drives the fixing plate 24 to approach both sides of the rubber seal. Then the rubber seal is squeezed and fixed. Then, by pressing the button 8 on the controller 7 on one side of the workbench 1, the electric telescopic rod 5 on the bracket 4 is started, so that the pressing block 6 on one side of the electric telescopic rod 5 continuously presses the rubber seal on the workbench 1 with different forces. Then, the sensor 9 on one side of the workbench 1 collects data on the rubber seal under dynamic pressure. Then the dynamic pressure simulation test of the rubber seal is completed.
