[0022] In this embodiment, the inner side of the slot rod 59 is rotatably connected to the limit rod 519, and the limit rod 519 and the lower end of the L-shaped plate 58 are fixedly connected to a movable plate 520.

[0025] Specifically, the circular plate 2, pushed by the push plate 611, will squeeze into between the two groups of extension shells 533 and stretch them apart until the circular plate 2 enters between the two groups of clamping shells 527. During the process, the extension shell 533 and the clamping shell 527 will move forward due to the squeezing of the circular plate 2, so that the third slider 528 and the fourth slider 531 slide on the inner side of the fourth slide groove 532 at the same time. At the same time, the spring 529 will be compressed, and the moving cylinder 526 will also move toward the inner side of the connecting cylinder 524. By sliding the block 530 on the inner side of the third slide groove 525, the clamping shell 527 can move smoothly to avoid displacement during the movement, thereby avoiding affecting the clamping effect.

[0026] In this embodiment, a support column 537 is fixedly connected to the upper end of the base 1, and the support column 537 is located below the impact head 54. An annular groove 538 is provided on the surface of the output end of the cylinder 53. The feeding mechanism 6 includes a ring block 61, and the ring block 61 is rotatably connected to the inner side of the annular groove 538. A connecting rod 1 62 is fixedly connected to the outer side of the ring block 61, and a connecting rod 2 63 is fixedly connected to one end of the connecting rod 1 62. The connecting rod 2 63 is slidably connected between the two groups of mounting plates 51, and two groups of connecting rods 3 64 are fixedly connected to one side of the connecting rod 2 63.

[0027] Specifically, the cylinder 53 is started to shrink, and the impact head 54 moves upward at the same time. During the process, the connecting rod 1 62 is driven to move upward at the same time through the ring block 61, and then the first tooth plate 65 is driven to move upward under the connection of the connecting rod 2 63 and the connecting rod 3 64, so that it can be moved out from the inner side of the groove 66.

[0028] In this embodiment, the two groups of connecting rods three 64 are symmetrical to each other, one end of the connecting rod three 64 is fixedly connected to the first tooth plate 65, the upper end of the workbench 3 is provided with a groove 66, the first tooth plate 65 is movably connected to the inner side of the groove 66, the upper end of the workbench 3 is fixedly connected to two groups of fixed blocks 67, the opposite sides of the two groups of fixed blocks 67 are rotatably connected to gear three 68, the gear three 68 is meshed with the first tooth plate 65, the lower end of the gear three 68 is meshed with the second tooth plate 69, the lower end of the second tooth plate 69 is slidably connected to the fixed seat 610, and the lower end of the fixed seat 610 is fixedly connected to the workbench 3.

[0029] Specifically, the first tooth plate 65 meshes with the gear three 68, and when the gear three 68 rotates, it will mesh with the second tooth plate 69 at the same time, so that the second tooth plate 69 moves, and when the second tooth plate 69 moves, it will drive the push plate 611 to move, thereby pushing the circular plate 2 to move toward the extension shell 1 533.

[0030] In this embodiment, a push plate 611 is fixedly connected between the two groups of second tooth plates 69, and the lower end of the push plate 611 is in contact with the surface of the workbench 3. One side of the push plate 611 is rotatably connected to a sub-plate 612 through a rotating shaft. The front and rear ends of the sub-plate 612 are fixedly connected to a third tooth plate 613, and the third tooth plate 613 is meshed with the gear three 68. The outer sides of the push plate 611 and the sub-plate 612 are fixedly connected with a spring piece 614. A connecting groove 615 is provided at the upper end of the workbench 3, and the spring piece 614 is movably connected to the inner side of the connecting groove 615.

[0031] Specifically, when the second tooth plate 69 moves, since the auxiliary plate 612 is connected to the push plate 611 through the rotating shaft, the auxiliary plate 612 is pulled by the push plate 611 and moves with it. After being affected by the workbench 3, it flips from vertical to a state flush with the second tooth plate 69, and then continues to move upward with the first tooth plate 65, which will cause the third tooth plate 613 to continue to mesh with the gear three 68. In addition, when the output end of the cylinder 53 pushes the impact head 54 downward, it will drive the ring block 61 and the connecting rod 1 62 to move downward, meshing with the gear three 68 to make it rotate in the opposite direction, thereby moving the push plate 611 back to its original position, and the auxiliary plate 612 is flipped from horizontal to vertical under the pull of the spring piece 614.

[0032] When in use, the base 1 is placed on a horizontal ground, and then the circular plate 2 that needs to be strength tested is placed between the two sets of fixed seats 610, and then the cylinder 53 is started to shrink it, and the impact head 54 moves upward at the same time. During the process, the connecting rod 1 62 is driven to move upward at the same time through the ring block 61, and then the first tooth plate 65 is driven to move upward under the connection of the connecting rod 2 63 and the connecting rod 3 64, so that it moves out from the inner side of the groove 66, and the first tooth plate 65 is meshed with the gear 3 68. When the gear 3 68 rotates, it will mesh with the second tooth plate 69 at the same time, so that the second tooth plate 69 moves, and when the second tooth plate 69 moves, it will drive the push plate 611 to move, thereby pushing the circular plate 2 to move toward the extension shell 1 533. In addition, when the second tooth plate 69 moves, because the auxiliary plate 612 is connected to the extension shell 1 533 through the rotating shaft, the auxiliary plate 612 is connected to the extension shell 1 533 through the rotating shaft. The push plate 611 is connected, and the auxiliary plate 612 is pulled by the push plate 611 and moves with it. After being affected by the workbench 13, it flips from vertical to a state flush with the second tooth plate 69, and then continues to move upward with the first tooth plate 65, so that the third tooth plate 613 continues to mesh with the gear 3 68. After the circular plate 2 moves into between the two groups of extension shells 1 533, the circular plate 2 will squeeze into between the two groups of extension shells 1 533 under the push of the push plate 611 and stretch the two groups apart until the circular plate 2 enters between the two groups of clamping shells 527. During the process, the extension shell 1 533 and the clamping shell 527 are squeezed by the circular plate 2 and move forward, so that the third slider 528 and the fourth slider 531 slide on the inner side of the fourth slide groove 532 at the same time. At the same time, the spring 529 is compressed, and the moving cylinder 5 26 also moves to the inner side of the connecting cylinder 524, and the block 530 slides on the inner side of the third slide groove 525, so that the clamp shell 527 can move smoothly to avoid its deviation. After the circular plate 2 is clamped between the two groups of clamp shells 527 under the action of the spring 529, the cylinder 53 is started again. At this time, the impact head 54 impacts the circular plate 2 under the output of the cylinder 53, and then the motor 517 is started. The motor 517 rotates the gear 2 518, and the gear 2 518 rotates the pulley 514 by meshing with the gear 1 516. The two groups of pulleys 514 can rotate at the same time under the connection of the belt 515, which makes the two groups of groove rods 59 rotate together. As the groove rod 59 rotates, the sliding ball 512 enters the U-shaped groove from the original position of the straight groove 510 511, as the slot rod 59 continues to rotate, the sliding ball 512 and the L-shaped plate 58 will be prompted to move downward, and the clamping shell 527 will move downward under the connection between the third slider 528 and the connecting plate 521, so as to press the edge of the circular plate 2 downward, and then the circular plate 2 is supported by the support column 537 to achieve the operation of bending the circular plate 2. Through the set U-shaped groove 511, as the slot rod 59 continues to rotate, the sliding ball 512 can slide to the position of the straight groove 510 again, so that the L-shaped plate 58 drives the moving plate 520 to move back to its original position again, so that the circular plate 2 for testing the bending force returns to its original state, and the motor 517 stops outputting. Next, the staff will continue to put the next group of circular plates 2 to be tested between the two groups of fixed seats 610.Just repeat the above steps, and the next group of circular plates 2 to be tested will also be pushed by the push plate 611 to move toward the extension shell 1 533. When the next group of circular plates 2 moves between the two groups of clamping shells 527, the circular plates 2 tested in the previous group will be pushed out, so that the circular plates 2 after the bending test will move to the workbench 2 4 through the extension shell 2 534. After the next group of circular plates 2 enters between the two groups of clamping shells 527, the circular plates 2 after the bending test will then be squeezed by the two groups of clamping plates 536, and the side surfaces will also be tested for strength, and then collected by the staff for the next step.
