[0017] The present invention also provides an adjustable tooling adjustment method for a vibration impact test, comprising the following steps:

[0018] S1. Place the material to be tested on the top of the vibration test bench, start the fifth motor, so that the fifth motor drives the first bevel gear to rotate, and then drives the second bevel gear to rotate through the shape of the first bevel gear, so that the second bevel gear can drive the second connecting rod to rotate on the inner wall of the vibration test bench during rotation, and then drives the third bevel gear to rotate through the rotation of the second connecting rod. After the third bevel gear drives the fourth bevel gear to rotate, the fourth bevel gear drives the bidirectional screw to rotate, and drives the first limit plate and the second limit plate to move through the threads arranged on the outer wall of the bidirectional screw, so that the first limit plate and the second limit plate move in opposite directions, and clamps the material to be tested placed on the top of the vibration test bench so that its position is fixed in the middle of the top of the vibration test bench, and then controls the control console through the control button and then starts the vibration test bench through the signal transmission line, so that the vibration test bench emits vibration to detect the vibration impact of the material to be tested;

[0020] S3. Start the third motor. The third motor can drive the first connecting rod to rotate and then drive the screw sleeve to rotate. Since the screw sleeve and the flip gear are meshingly connected, the screw sleeve drives the flip gear to rotate when rotating, and then drives the connecting frame and the flip suction cup to rotate, so that they can rotate back and forth, so that the flip suction cup can absorb the material to be tested and rotate back and forth. When the fourth motor is started, it can drive the flip frame and the component installed on the flip frame to rotate left and right, so that the flip suction cup can rotate at multiple angles when absorbing the material to be tested, and can flip the absorbed material to be tested by cooperating with the lifting component, so that after completing the vibration and impact test on one side of the material, the vibration resistance of other sides of the material can be monitored.

[0021] Compared with the existing technology, the advantages of the adjustable tooling for vibration impact test are:

[0022] The present invention cooperates with structures such as a connecting seat, a first connecting rod, and a third motor so that after the third motor is started, the third motor can drive the first connecting rod to rotate and then drive the screw sleeve to rotate. Since the screw sleeve and the flip gear are meshingly connected, the screw sleeve drives the flip gear to rotate when rotating and then drives the connecting frame and the flip suction cup to rotate, so that they can rotate back and forth, so that the flip suction cup can absorb the material to be tested and rotate back and forth. When the fourth motor is started, it can drive the flip frame and the component installed on the flip frame to rotate left and right, so that the flip suction cup can rotate at multiple angles when absorbing the material to be tested, and can flip the absorbed material to be tested by cooperating with the lifting component, so that after completing the vibration impact detection of one side of the material, the vibration resistance of other sides of the material can be monitored, so as to achieve the purpose of facilitating vibration detection of multiple sides of the material.

[0023] The present invention cooperates with structures such as the first motor, the connecting shaft, and the mounting plate, so that due to the chain meshing connection with the inner walls of the first sprocket and the second sprocket, the first sprocket or the second sprocket can drive the lifting bracket fixed on one side of the chain to lift and lower when rotating, and then lift and lower the lifting bracket and the first motor fixed on the lifting bracket. Starting the first motor can drive the connecting shaft to rotate and then drive the mounting plate to rotate, so as to ensure that the flipping suction cup can rotate after sucking the material to be tested. Starting the second motor can drive the transmission screw to rotate and then drive the position of the flipping table to move on the mounting plate through the thread set on the outer wall of the transmission screw, so that the flipping suction cup can contact the material to be tested placed in the middle of the top of the vibration test table and suck it, so as to achieve the purpose of facilitating the device to suck and rotate and then move left and right to achieve the flipping effect.

[0024] The present invention arranges the coordination of structures such as a fixed seat, a fifth motor, and a first bevel gear, so that the device can place the material to be tested on the top of the vibration test bench, start the fifth motor, so that the fifth motor drives the first bevel gear to rotate, and then drives the second bevel gear to rotate through the shape of the first bevel gear, so that the second bevel gear can drive the second connecting rod to rotate on the inner wall of the vibration test bench during rotation, and then drives the third bevel gear to rotate through the rotation of the second connecting rod. After the third bevel gear drives the fourth bevel gear to rotate, the fourth bevel gear drives the bidirectional screw to rotate, and drives the first limit plate and the second limit plate to move through the thread arranged on the outer wall of the bidirectional screw, so that the first limit plate and the second limit plate move oppositely, and clamp the material to be tested placed on the top of the vibration test bench, so that its position is fixed in the middle of the top of the vibration test bench, at this time, the control console is controlled by the control button and then the vibration test bench is started through the signal transmission line, so that the vibration test bench emits vibration to detect the vibration impact of the material to be tested.
