At this time, the mounting block 33 is away from the inside of the fixed plate 32, and the detection pressure plate 108 is away from the surface of the stabilizing suction cup 35, so that the detection pressure plate 108 is removed from the surface of the lifting plate 103, and the detection pressure plate 108 is replaced to realize the function of facilitating the assembly of the detection pressure plate 108 by the crack detection tooling.

[0029] Furthermore, if Figure 2 and Figure 5As shown, the surfaces of the lifting plate 103 and the containing box 104 are both provided with an efficient sealing mechanism 4, the interior of the efficient sealing mechanism 4 includes a first sealing gasket 41, a sealing frame 42 and an efficient sealing component 43, the efficient sealing component 43 is arranged on the surfaces of the lifting plate 103 and the containing box 104, the efficient sealing component 43 is composed of a guide groove 431, a sealing spring 432 and a second sealing gasket 433, the surface at the top position of the containing box 104 is installed with a first sealing gasket 41 for sealing between the containing box 104 and the lifting plate 103, the surface at the bottom position of the lifting plate 103 is installed with a sealing frame 42, the interior of the sealing frame 42 is provided with a second sealing gasket 433 for sealing between the containing box 104 and the air pump 107, the inner walls on both sides of the sealing frame 42 are provided with guide grooves 431, the guide grooves 431 and the surface of the second sealing gasket 433 are slidably matched with each other, the interior of the sealing frame 42 is installed with a sealing spring 432, and one end of the sealing spring 432 is fixed to the surface of the second sealing gasket 433.

[0030] During implementation, the lifting plate 103 drives the sealing frame 42 to move downward. At this time, the surface of the first sealing gasket 41 moves to the inside of the sealing frame 42, and the first sealing gasket 41 squeezes the second sealing gasket 433 inside the sealing frame 42 upward, and drives the second sealing gasket 433 to move under the elastic force of the sealing spring 432 inside the sealing frame 42, so that the second sealing gasket 433 slides inside the guide groove 431, and the second sealing gasket 433 is guided by the guide groove 431.

[0031] Working principle: When in use, first place the tool box 1 at the designated position, and then place the sheet metal to be tested inside the placement slot 111 on the surface of the storage box 104. Under the action of the level tester 109, the placement of the sheet metal is tested to see if it is in a horizontal position, so that the sheet metal can be kept horizontal when placed. At this time, the elastic column 21 inside the slot 22 and the extension spring 231 drive the clamping plate 233 to move, so that the clamping plate 233 moves inside the placement slot 111. At this time, The elastic force of the spring body 232 inside the placement groove 111 drives the clamping plate 233 to move to contact the surface of the sheet metal part. Under the joint action of the spring body 232 and the clamping plate 233, the sheet metal part to be inspected is horizontally clamped inside the placement groove 111 to realize the function of the crack detection tooling to place the sheet metal part horizontally, so that the sheet metal part can be placed horizontally inside the placement groove 111 when the crack detection tooling is used, so that the result of the crack detection tooling detecting the surface of the sheet metal part is more accurate.

[0032] Then, the user places the detection pressure plate 108 at the bottom of the lifting plate 103, so that the detection pressure plate 108 drives the mounting block 33 to slide inside the mounting groove 31, and the detection pressure plate 108 is guided under the joint action of the mounting groove 31 and the mounting block 33. At this time, the mounting block 33 is stuck to the inside of the fixing plate 32, and the detection pressure plate 108 can be stably installed at the bottom of the lifting plate 103 under the action of the stabilizing suction cup 35 inside the receiving groove 34. When the user needs to replace the detection pressure plate 108, the user pulls the detection pressure plate 108 downward, so that the detection pressure plate 108 drives the detection pressure plate 108 to slide inside the mounting groove 31. The mounting block 33 slides inside the mounting groove 31. At this time, the mounting block 33 is away from the inside of the fixing plate 32, and the detection platen 108 is away from the surface of the stabilizing suction cup 35, so that the detection platen 108 is removed from the surface of the lifting plate 103, and the detection platen 108 is replaced to realize the function of facilitating the assembly of the detection platen 108 by the crack detection tooling, so that the user can conveniently assemble the detection platen 108 on the surface of the lifting plate 103 when using the crack detection tooling, so that the crack detection tooling can regularly replace the detection platen 108 to ensure the detection effect on the surface of the sheet metal.

[0033] Subsequently, the user operates the control button 101 on the surface of the tooling box 1, so that the control button 101 controls the electric push rod 106 inside the fixed box 102 to work, and the electric push rod 106 drives the lifting plate 103 to slide on the surface of the guide rod 105, and the lifting plate 103 is guided by the guide rod 105. At this time, the lifting plate 103 drives the detection pressing plate 108 to move downward to the inside of the placement groove 111, and the detection pressing plate 108 will press down the sheet metal to be detected. Then, the air pump 107 is controlled to work through the control button 101, and the air pump 107 inflates the inside of the placement groove 111 through the tube body 110. If cracks occur on the surface of the sheet metal to be inspected, the ultrasonic detector 112 will transmit ultrasonic waves to the surface of the sheet metal to be inspected through the detection platen 108 and reflect them in whole or in part. The defects such as pores, cracks, delamination (there is gas in the defects) or inclusions on the surface of the sheet metal to be inspected will be processed by the internal circuit of the ultrasonic detector 112, and waveforms of different heights and certain intervals will be displayed on the fluorescent screen of the ultrasonic detector 112. Finally, the depth, position and shape of the defect in the sheet metal to be inspected are judged according to the changing characteristics of the waveform and transmitted to the inside of the control button 101 to complete the crack detection on the surface of the sheet metal.

[0034] Subsequently, when the lifting plate 103 drives the detection pressing plate 108 to move downward, the lifting plate 103 drives the sealing frame 42 to move downward. At this time, the surface of the first sealing gasket 41 moves to the inside of the sealing frame 42, and the first sealing gasket 41 presses the second sealing gasket 433 inside the sealing frame 42 upward. Under the elastic force of the sealing spring 432 inside the sealing frame 42, the second sealing gasket 433 is driven to move, so that the second sealing gasket 433 slides inside the guide groove 431. Under the action of the guide groove 431, the second sealing gasket 433 is guided. When one end of the first sealing gasket 41 moves to the inside of the sealing frame 42, the sealing gasket 433 is pressed upward. After the parts are installed, the lifting plate 103 and the containing box 104 are sealed under the joint action of the first sealing gasket 41 and the second sealing gasket 433, so that a sealed cavity is formed between the lifting plate 103 and the containing box 104, so that the detection tooling has a better detection effect on the surface of the sheet metal part, so as to realize the function of the crack detection tooling to efficiently seal the lifting plate 103 and the containing box 104, so that when the crack detection tooling is used, the lifting plate 103 and the containing box 104 can achieve a better sealing effect, making the crack detection tooling more practical when in use, and finally completing the use of the crack detection tooling.
