[0026] Embodiment 1

[0027] An automotive sheet metal stamping part gap detection tool, as Figure 1 , Figure 2 shown, includes a detection box 2 and a clamping mechanism. The clamping mechanism is located inside the detection box 2 and is used to clamp the sheet metal stamping part in the middle of one side of the detection box 2; it also includes a control system and an ultrasonic sensor 4. The ultrasonic generating end of the ultrasonic sensor 4 penetrates through the middle of the side wall of the detection box 2 and extends into the detection box 2, and the ultrasonic sensor 4 is communicatively connected to the control system.

[0028] For the above automotive sheet metal stamping part gap detection tool, during use, the sheet metal stamping part is clamped and fixed inside the detection box 2 through the clamping mechanism, so that the sheet metal stamping part is located in the middle of one side of the detection box 2. Subsequently, the ultrasonic sensor 4 located in the middle of the side wall of the detection box 2 is activated. The ultrasonic generating end of the ultrasonic sensor 4 sends ultrasonic waves to the sheet metal stamping part, and then receives the ultrasonic waves reflected from the surface of the sheet metal stamping part. The ultrasonic sensor 4 transmits the data to the control system, calculates the distance to the object surface, and thus can measure the gap of the sheet metal stamping part. In this embodiment, the gap is measured by the ultrasonic sensor 4, which does not need to be in direct contact with the object to be measured, and the measurement is carried out by ultrasonic waves. The color or transparency of the object, as well as the ambient light or dust, etc. will not affect the measurement result, which can improve the measurement accuracy of the automotive sheet metal stamping part gap and the reliability of the measurement result.

[0029] AsFigure 1 , Figure 2 As shown in Figure 2 , the control system includes an analysis server 5 and a display screen 6. The ultrasonic sensor 4 and the display screen 6 are respectively communicatively connected to the analysis server 5. During implementation, after the clamping mechanism clamps and fixes the sheet metal stamping part, the ultrasonic sensor 4 is started. The ultrasonic transmitting end of the ultrasonic sensor 4 sends ultrasonic waves to the surface of the sheet metal stamping part, and then receives the ultrasonic waves reflected from the surface of the sheet metal stamping part. After that, the ultrasonic sensor 4 uploads the data to the analysis server 5. The analysis server 5 can calculate the distance to the object surface based on the time and amplitude of the reflected wave, and thus can measure the gap of the sheet metal stamping part. The analysis server 5 reflects the measured data on the display screen 6 for display.

[0030] As Figure 1 , Figure 2 shown in Figure 2 , it further includes an audible and visual alarm 7. The analysis server 5 is communicatively connected to the audible and visual alarm 7. Specifically, the audible and visual alarm 7 is provided at the top of the display screen 6. During implementation, the analysis server 5 reflects the measured data on the display screen 6 and issues an alarm through the audible and visual alarm 7.

[0031] As Figure 1 , Figure 2 shown in Figure 2 , it further includes a bottom plate 1 and a support mechanism 3. The detection box 2 and the support mechanism 3 are respectively located at both ends of the top of the bottom plate 1. The analysis server 5 and the display screen 6 are respectively installed on the support mechanism 3. During implementation, the detection box 2 and the support mechanism 3 are fixed through the bottom plate 1, thereby realizing the fixation of the clamping mechanism, the ultrasonic sensor 4, the analysis server 5, and the display screen 6, and ensuring that the sheet metal stamping part clamped and fixed by the clamping mechanism can be aligned with the ultrasonic sensor 4.

[0032] As Figure 1 , Figure 2 shown in Figure 2 , the support mechanism 3 includes support legs 301 and a support frame 302. The support frame 302 is a cuboid structure with an open side. The bottom of the support leg 301 is fixedly connected to the bottom plate 1, the top of the support leg 301 is connected to the support frame 302, the analysis server 5 is connected to the inner wall of the bottom of the support frame 302, and the display screen 6 is located at the top of the support frame 302. Specifically, the front and back of the support frame 302 are both open and communicate with the side opening, so that the cross-section of the support frame 302 is in a "U" shape, facilitating the installation of the analysis server 5.

[0033] Embodiment 2

[0034] This embodiment is similar to Embodiment 1, the difference is that, as Figure 2As shown in the figure, the clamping mechanism includes two groups of clamping components, which are relatively arranged on the inner wall of the top of the detection box 2 and the inner wall of the bottom of the detection box 2. During implementation, the sheet metal stamping part is placed between the two groups of clamping components, and the two groups of clamping components gradually approach each other on the opposite sides to fixedly clamp the sheet metal stamping part.

[0035] As Figure 2 shown in the figure, the clamping component includes an electric push rod 8 and a fixing plate 12. The electric push rod 8 is installed on the inner wall of the detection box 2, and the output end of the electric push rod 8 is connected to the fixing plate 12. During implementation, the sheet metal stamping part is placed between the two fixing plates 12, and the two electric push rods 8 respectively push the two fixing plates 12 to approach each other until the two fixing plates 12 fixedly clamp the sheet metal stamping part, realizing the clamping and positioning of the sheet metal stamping part. Among them, the distance that the electric push rod 8 pushes the fixing plate 12 to move can be adjusted to adjust the distance between the two fixing plates 12, facilitating the clamping and fixing of sheet metal stamping parts of different sizes.

[0036] As Figure 2 shown in the figure, the clamping component further includes a buffer pad 13, and the buffer pad 13 is arranged on the side of the fixing plate 12 away from the electric push rod 8. During implementation, when the two electric push rods 8 respectively push the two fixing plates 12 to fixedly clamp the sheet metal stamping part, a certain buffer space is reserved in cooperation with the buffer pad 13 to protect the sheet metal stamping part during clamping and prevent damage to the surface of the sheet metal stamping part.

[0037] Embodiment Three

[0038] This embodiment is similar to Embodiment Two, the difference being that the clamping component further includes a shock absorption structure, and the output end of the electric push rod 8 is connected to the fixing plate 12 through the shock absorption structure. When the electric push rod 8 drives the fixing plate 12 to clamp the sheet metal stamping part, the shock absorption structure can play a role in shock absorption and buffering.

[0039] As Figure 3 shown in the figure, the shock absorption structure includes a connecting plate 9, a telescopic rod 10 and a spring 11. The output end of the electric push rod 8 is connected to the connecting plate 9, the two ends of the telescopic rod 10 are respectively connected to the connecting plate 9 and the fixing plate 12, the spring 11 is wound around the outer periphery of the telescopic rod 10, and the two ends of the spring 11 are respectively connected to the connecting plate 9 and the fixing plate 12. During implementation, the electric push rod 8 pushes the fixing plate 12 through the connecting plate 9 and the telescopic rod 10, and the two fixing plates 12 are used to clamp the sheet metal stamping part, and the telescopic rod 10 and the spring 11 play a role in shock absorption and buffering, improving the stability and accuracy of clamping.

[0040] Specifically, both the connecting plate 9 and the fixing plate 12 are in the shape of rectangular plates. In each set of clamping components, there are four telescopic rods 10 and four springs 11. The four telescopic rods 10 are connected between the four vertices of the connecting plate 9 and the four vertices of the fixing plate 12 to ensure the smooth movement of the fixed block when the electric push rod 8 pushes the fixed block through the connecting plate 9. The buffer pad 13 is in the shape of a rectangular plate, and the length and width of the buffer pad 13 correspond to the length and width of the fixing plate 12 one by one.

[0041] The working process of the gap detection tool for automotive sheet metal stamping parts in this embodiment is as follows: Place the sheet metal stamping part between the two fixing plates 12, and then start the electric push rod 8. The electric push rod 8 drives the corresponding fixing plate 12 to move towards each other, so as to fixedly clamp the sheet metal stamping part through the two fixing plates 12, and cooperate with the buffer pad 13 to reserve a certain buffer space to prevent damage to the surface of the sheet metal stamping part. The telescopic rods 10 and the springs 11 play a role in shock absorption and buffering to improve the stability and accuracy of clamping, and achieve the purpose of clamping and positioning. Then start the ultrasonic sensor 4. The ultrasonic generating end of the ultrasonic sensor 4 sends ultrasonic waves to the surface of the sheet metal stamping part, and then receives the ultrasonic waves reflected from the surface of the sheet metal stamping part. After that, the ultrasonic waves upload the data to the analysis server 5. The analysis server 5 calculates the distance from the object surface based on the time and amplitude of the reflected wave, and then can measure the gap of the sheet metal stamping part. The analysis server 5 reflects the measured data on the display screen 6 for display and issues an alarm through the sound and light alarm 7.

[0042] In the specific content of the above specific implementation manner, the technical features can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should be considered as the scope recorded in this specification.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manner of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
