[0003] The existing ones do not have precise positioning of the products to be measured, and the products to be measured may not provide sufficient stability, which may cause the products to be measured to shake or shift during the testing process, resulting in deviation of the measurement data, thereby affecting the accuracy and reliability of the test results.

[0004] For example, an auxiliary pneumatic pressing test fixture disclosed in the patent with the publication number CN216209563U. The product to be measured in this patent is directly placed inside the product fixing frame, and the size of the product fixing frame is fixed. Therefore, it can only effectively fix and support those products to be measured whose sizes match or are slightly smaller than its size. However, this product fixing frame with a fixed size also brings certain limitations in flexibility. For products to be measured with different sizes or shapes, it may be necessary to design product fixing frames with different sizes to adapt, thereby reducing the adaptability and flexibility of the test fixture.

[0005] Therefore, it is very necessary to invent a quick-clamping pneumatic test fixture to solve the above problems. Summary of the Utility Model

[0009] Preferably, a detection probe is arranged below the mounting plate, and a detection table is arranged directly below the detection probe to ensure that the detection probe can accurately contact and test the object to be measured placed on the detection table.

[0010] Preferably, there are 4 adjusting rods. One end of each of the four adjusting rods is hingedly connected to the driving plate to achieve flexible transmission between the driving plate and the adjusting rods, and further control the horizontal movement of the sliding block and the moving block.

[0011] Preferably, the other ends of the four adjusting rods are hingedly connected to the vertical frame to achieve flexible transmission between the driving plate and the vertical frame.

[0012] Preferably, a sliding groove is formed at the contact position between the sliding block and the support plate, and the sliding block is slidably connected to the sliding groove, so that the sliding block can slide smoothly in the sliding groove of the support plate to achieve precise adjustment in the horizontal direction.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the drawings.

[0025] The present utility model provides a kind of quick-clamping pneumatic test fixture as Figures 1-5 shown, which includes a base 1, a detection probe 6, a detection table 7 and a limit clamping block 17. A machine shell 2 is arranged above the base 1, a cylinder 3 is arranged at the top of the machine shell 2, an output end of the cylinder 3 is provided with a mounting plate 4, a guide rod 5 is arranged through the mounting plate 4, a bottom surface of the guide rod 5 is fixedly installed on the base 1, a top surface of the guide rod 5 is fixedly installed on the machine shell 2, there are 4 guide rods 5, and the four guide rods 5 are slidably connected with the mounting plate 4. A detection probe 6 is arranged below the mounting plate 4, a detection table 7 is arranged directly below the detection probe 6, a detection table 7 is arranged above the base 1, a support plate 8 is arranged below the detection table 7, a hydraulic cylinder 9 is arranged at the center of the bottom of the detection table 7 and penetrates through to the support plate 8, an output end of the hydraulic cylinder 9 is provided with a drive plate 10, an adjusting rod 11 is arranged on the drive plate 10, a vertical frame 12 is arranged above the adjusting rod 11, a sliding block 13 is arranged above the vertical frame 12, a moving block 15 is arranged above the sliding block 13, and a limit clamping block 17 is arranged on a side wall of the moving block 15.

[0026] There are 4 adjusting rods 11. One end of each of the four adjusting rods 11 is hinged to the driving plate 10, and the other end of the four adjusting rods 11 is hinged to the vertical frame 12. A sliding groove 14 is provided at the contact position between the sliding block 13 and the support plate 8, and the sliding block 13 is slidably connected to the sliding groove 14. A moving groove 16 is provided at the contact position between the moving block 15 and the testing table 7, and the moving block 15 is slidably connected to the moving groove 16. There are 4 limiting clamping blocks 17, and the four limiting clamping blocks 17 are located around the testing table 7 above.

[0027] When the provided hydraulic cylinder 9 drives the driving plate 10 to move up and down, it allows the angle of the adjusting rod 11 to change when the driving plate 10 moves. Through the angle change of the adjusting rod 11, the vertical movement of the driving plate 10 is converted into the horizontal movement of the vertical frame 12, realizing the displacement adjustment in the horizontal direction. A sliding groove 14 is provided on the support plate 8, and the sliding block 13 is slidably connected to the sliding groove 14. As the vertical frame 12 moves, the sliding block 13 slides in the sliding groove 14, and a moving groove 16 is provided on the testing table 7, and the moving block 15 is slidably connected to the moving groove 16. As the sliding block 13 moves, the moving block 15 slides in the moving groove 16. Thus, as the moving block 15 moves, the limiting clamping blocks 17 will also adjust their positions accordingly, so that the four limiting clamping blocks 17 surround the test object from all around, providing an even clamping force to prevent the test object from tilting or moving.

[0028] The working principle of the present utility model:

[0029] Refer to the attached Figures 1-5 description. When using the present utility model, first place the object to be tested on the testing table 7 and ensure its correct position. Start the hydraulic cylinder 9 through the control system. The hydraulic cylinder 9 drives the driving plate 10 to move upward. The movement of the driving plate 10 is converted into the horizontal movement of the vertical frame 12 through the adjusting rod 11. The movement of the vertical frame 12 drives the sliding block 13 to slide in the sliding groove 14 of the support plate 8. The moving block 15 connected above the sliding block 13 slides in the moving groove 16 of the testing table 7 as the sliding block 13 moves. This sliding connection ensures that the moving block 15 can move smoothly and precisely. As the moving block 15 moves, the four limiting clamping blocks 17 provided on its side wall also adjust their positions accordingly;

[0030] When the limiting clamping blocks 17 move to the appropriate positions, the four limiting clamping blocks 17 will move synchronously to clamp the test object on the testing table 7 to ensure that it remains stable and immovable during the test. After the position of the object to be tested is fixed, the cylinder 3 can be started through the control system. The cylinder 3 pushes the mounting plate 4 and the detection probe 6 to approach and contact the test object for the required test operation. After the test is completed, control the cylinder 3 and the hydraulic cylinder 9 to move in the reverse direction through the control system to make the detection probe 6 and the limiting clamping blocks 17 return to their initial positions, and then take out the test object.
