[0024] The clamping mechanism includes a clamping block 38, which is slidably connected to the inside of the rectangular groove 39. A push rod 42 is fixedly connected to the bottom end of the clamping block 38. A second spring 44 is sleeved on the push rod 42. The second spring 44 is fixedly connected to the inner wall of the first movable groove 43. The side of the push rod 42 away from the clamping block 38 abuts against the top block 40. A third spring 45 is fixedly connected to the top block 40. The side of the third spring 45 away from the top block 40 is fixedly connected to the inner wall of the second movable groove 46. The rectangular groove 39, the first movable groove 43 and the second movable groove 46 are all provided inside the movable plate 27.

[0025] Two groups of circular grooves 29 are formed inside the movable plate 27. A first spring 30 is fixedly connected to the inner wall of the circular groove 29. The first spring 30 is sleeved on an insertion rod 31. The side of the first spring 30 away from the movable plate 27 is fixedly connected to the fixed plate 24. The insertion rod 31 is inserted into the fixed plate 24.

[0026] In the above-mentioned technology, a powder coating impact tester often needs to impact the test board multiple times in order to ensure the reliability of the experimental results during the coating detection process. After each impact, the operator needs to manually adjust the position of the test board, which is relatively cumbersome. Through the structural design of the moving mechanism, the test board placed on the placement slot 28 can be moved on the device body 1 by moving the moving block 22 on the threaded rod 21, so as to facilitate changing the position of the test board on the device body 1, so as to achieve the purpose of the device body 1 being able to facilitate impact detection of different positions on the test board. Driven by the motor 23, the cavity 20 inside The threaded rod 21 will rotate and make the two groups of moving blocks 22 threadedly connected on the threaded rod 21 move in the same direction. The moving block 22 is fixed to the bottom end of the fixed plate 24, so the fixed plate 24 can move left and right on the device body 1. A moving plate 27 is slid on the fixed plate 24 through the slider 25 and the slide groove 26. The test plate placed on the placement groove 28 will move with the movement of the fixed plate 24, thereby changing the position of the test plate, so that the device body 1 can perform impact detection on different positions of the test plate. The slider 25 and the slide groove 26 are both trapezoidal in design, so that the moving plate 27 can slide on the fixed plate 24 without being separated from the fixed plate 24.

[0027] Through the structural design of the clamping mechanism, it is only necessary to press the top blocks 40 on the two sets of fixed plates 24 inward at the same time to make the clamping block 38 move in the opposite direction on the placement groove 28, thereby releasing the clamping and fixing of the test board placed on the placement groove 28 by the clamping block 38, so as to facilitate the fixing of the test board on the placement groove 28 and removing it from the placement groove 28. By pressing the top block 40 inward, the top block 40 will push the two sets of push rods 42 to move to both sides, and the push rods 42 and the bottom ends of the clamping block 38 are fixed together, so that the clamping block 38 will be separated from the test board, and the test board can be easily removed at this time. The placement groove 28 is opened on the movable plate 27 to facilitate the placement of the test board, and the position of the test board on the movable plate 27 is fixed to avoid movement during the test process.

[0028] The fixed plate 24 is designed to be L-shaped as a whole, and through the first spring 30 and the insertion rod 31, the movable plate 27 can slide back and forth on the fixed plate 24, so that its position can be changed by pushing the movable plate 27, so that the equipment body 1 can perform impact detection on different positions on the test plate.

[0029] See also Figure 1 , Figure 2 and Figure 3The moving block 22 is fixedly connected with two groups of card blocks 34, which are slidably connected to the inside of the card slot 35, which is provided on the inner wall of the through slot 36, and the bottom end of the fixed plate 24 is fixedly connected with four groups of pulleys 33, which are slidably connected to the long slot 37, which is provided on the device body 1.

[0030] By sliding the card block 34 in the card slot 35, the movement of the movable block 22 in the vertical direction is restricted to ensure that the movable block 22 can move smoothly in the horizontal direction. At the same time, support is also provided for the bottom end of the fixed plate 24 to prevent the threaded rod 21 from being subjected to greater pressure. Four sets of pulleys 33 are fixed to the bottom end of the fixed plate 24. By sliding the pulleys 33 on the long slots 37, the fixed plate 24 can be more stable during movement and is less likely to shake.

[0031] See also Figure 3 , Figure 4 and Figure 5 One side of the top block 40 is conical in design, and a rounded corner is provided on the side of the push rod 42 close to the top block 40. A gasket 32 ​​is fixedly connected to the inner wall of the placement groove 28, and the gasket 32 ​​is made of rubber.

[0032] The top block 40 is conical in design and the push rod 42 is provided with corresponding rounded corners so that the top block 40 can better push the push rod 42 to move. The gasket 32 ​​is made of rubber material to increase the friction between the inner wall of the placement groove 28 and the two sides of the test board to facilitate the placement of the test board on the placement groove 28.

[0033] Working principle: In the prior art, a powder coating impact tester often needs to impact the test plate multiple times in order to ensure the reliability of the experimental results during the coating detection process. After each impact, the operator needs to manually adjust the position of the test plate, which is relatively cumbersome. The coating impact test device in this case uses the structural design of the moving mechanism. The test plate placed on the placement slot 28 can be moved on the device body 1 by moving the moving block 22 on the threaded rod 21, thereby facilitating the change of the position of the test plate on the device body 1, so as to achieve the purpose of the device body 1 being able to facilitate impact detection of different positions on the test plate. Driven by the motor 23, the threaded rod 21 inside the cavity 20 will rotate and cause the threaded rod 21 to move. The two groups of movable blocks 22 threadedly connected on the rod 21 move in the same direction, and the movable blocks 22 are fixed to the bottom end of the fixed plate 24, so that the fixed plate 24 can move left and right on the equipment body 1, and a movable plate 27 is slid on the fixed plate 24 through the slider 25 and the slide groove 26. The test plate placed on the placement groove 28 will move with the movement of the fixed plate 24, thereby changing the position of the test plate, so that the equipment body 1 can perform impact detection on different positions of the test plate, wherein the slider 25 and the slide groove 26 are both trapezoidal in design, so that the movable plate 27 can slide on the fixed plate 24 while not separating from the fixed plate 24. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
