A slide bar 5 and a second lead screw 6 are provided on the lifting frame 403, and a second servo motor 8 is provided on the lifting frame 403. An adjusting plate 7 is provided on the slide bar 5 and the second lead screw 6, and an ultrasonic generator 10 is installed on the adjusting plate 7 through a mounting structure 9. The lower end of the ultrasonic generator 10 is provided with an ultrasonic emitter 11 and a collection hood 12. The lower end of the base 1 is provided with feet. The roller 3 is rotatably installed inside the side plate 2, and a sprocket is provided at the end of the roller 3. A driven wheel is provided at one of the sprockets, a chain is provided on the sprocket, a motor is provided inside the base 1, and a driving wheel is provided on the motor. The driving wheel is connected to the driven wheel through a transmission chain. The adjusting plate 7 is installed on the slide bar 5 through a slider, and a nut seat is provided on the adjusting plate 7. The nut seat is threadedly connected to the second lead screw 6. The fixed rod 401 is fixed on the side plate 2, the fixed plate 402 is fixed on the fixed rod 401, the lifting frame 403 is connected to the fixed rod 401 through a movable plate, and a lifting plate is provided at the lower end of the lifting frame 403. The first servo motor 404 is installed on the lifting plate, and the first servo motor 404 is connected to a first lead screw 405. The first lead screw 405 passes through the fixed plate 402, and the first lead screw 405 is threadedly connected to the fixed plate 402.

[0020] When conducting the rivet inspection of the automotive battery box Pack, the base 1 is stably placed through the feet. The ultrasonic generator 10 is arranged below the adjusting plate 7 through the mounting structure 9. After starting the motor, the motor drives the roller 3 to rotate through the driving wheel, transmission chain and driven wheel. The rollers 3 are driven by sprockets and chains. The battery box is placed on the rollers 3 between the side plates 2, and the rollers 3 are used to drive the battery box to move. When the battery box passes below the lifting structure 4, the ultrasonic generator 10 generates ultrasonic waves that are emitted from the ultrasonic emitter 11. The ultrasonic waves act on the battery box to conduct ultrasonic inspection on the rivets. The reflected ultrasonic waves are collected through the collecting cover 12. By analyzing the collected reflected ultrasonic waves, the state of the rivets on the battery box can be obtained. If it is necessary to adjust the height of the ultrasonic generator 10, start the first servo motor 404 on the lifting plate. The first servo motor 404 drives the first lead screw 405 to rotate and lift relative to the fixed plate 402, thereby driving the lifting frame 403 to lift relative to the fixed rod 401, and then changing the height of the ultrasonic generator 10. If it is necessary to change the horizontal position of the ultrasonic generator 10, start the second servo motor 8 on the lifting frame 403. The second servo motor 8 drives the second lead screw 6 to rotate, and then drives the adjusting plate 7 to move through the nut seat. The adjusting plate 7 moves on the slide bar 5 through the slider, and then changes the horizontal position of the ultrasonic generator 10. After the ultrasonic generator 10 is adjusted, it can be used.

[0021] Through the above implementation solutions, the installation structure 9 includes a suspension mounting plate 901, an inverted L-shaped hole 902, a connecting rod 903, a round rod 904, a first pressing spring 905, and a round plate 906. The inverted L-shaped hole 902 is formed in the suspension mounting plate 901, and the suspension mounting plate 901 is fixed to the lower end of the adjusting plate 7. The connecting rod 903 is fixed to the side wall of the ultrasonic generator 10, and the connecting rod 903 is clamped in the inverted L-shaped hole 902. The round rod 904 is connected to the first pressing spring 905, and the round rod 904 is installed at the lower end of the adjusting plate 7. The round plate 906 is fixed to the lower end of the first pressing spring 905, and the round plate 906 abuts against the ultrasonic generator 10. A through hole is provided in the suspension mounting plate 901. The installation structure 9 further includes a pressing plate 907, an inclined plate 908, a movable screw 909, a second pressing spring 910, and a limit nut 911. The pressing plate 907 and the inclined plate 908 are fixedly connected, and the pressing plate 907 is fixedly connected to the movable screw 909. The movable screw 909 passes through the through hole in the suspension mounting plate 901. The second pressing spring 910 is sleeved on the movable screw 909. The limit nut 911 is connected to the movable screw 909. Through the provided installation structure 9, the ultrasonic generator 10 is clamped in the inverted L-shaped hole 902 of the suspension mounting plate 901 by the connecting rod 903, and the installation and disassembly of the ultrasonic generator 10 can be carried out quickly, facilitating the maintenance work. The first pressing spring 905 and the round plate 906 are provided on the round rod 904 to play a role of pressing the ultrasonic generator 10 downward, ensuring the stability of the ultrasonic generator 10. Through the provided pressing plate 907, in cooperation with the inclined plate 908, the movable screw 909, the limit nut 911, and the second pressing spring 910, it can not only ensure the stability of the ultrasonic generator 10 in the horizontal direction, but also automatically squeeze and make way during installation, without the need for extra operations, ensuring the pressing effect while not affecting the quick installation of the ultrasonic generator 10.

[0022] When installing the ultrasonic generator 10, move the circular plate 906 upward. The circular plate 906 moves towards the direction of the circular rod 904 and compresses the first abutting spring 905. Clip the ultrasonic generator 10 between the two hanging mounting plates 901, and insert the connecting rod 903 into the inverted L-shaped hole 902. During this process, after the ultrasonic generator 10 contacts the inclined plate 908, it generates a force on the inclined plate 908. After being stressed, the inclined plate 908 drives the abutting plate 907 to move, thereby compressing the second abutting spring 910. After the ultrasonic generator 10 moves between the two hanging mounting plates 901, lower the ultrasonic generator 10. The connecting rod 903 descends and contacts the lower end of the inverted L-shaped hole 902. Then, after releasing the circular plate 906, under the action of the first abutting spring 905, the circular plate 906 abuts against the ultrasonic generator 10 to play a role in abutting and fixing. At the same time, due to the action of the second abutting spring 910 on the movable screw rod 909, the abutting plate 907 contacts the side wall of the ultrasonic generator 10, playing a role in horizontally abutting and fixing the ultrasonic generator 10. When the ultrasonic generator 10 is installed and used, during use, due to the abutting effects in both the vertical and horizontal directions, the overall use stability of the ultrasonic generator 10 is high and the use effect is good. If the ultrasonic generator 10 needs to be disassembled, the staff directly move the ultrasonic generator 10 upward until the connecting rod 903 contacts the upper end of the inverted L-shaped hole 902, and then horizontally move the ultrasonic generator 10 to extract the connecting rod 903. After the ultrasonic generator 10 is disassembled, the circular plate 906 descends and resets under the action of the first abutting spring 905, while the abutting plate 907 resets under the action of the second abutting spring 910. During this process, the limit nut 911 on the movable screw rod 909 plays a limiting effect, which can prevent the detachment of the abutting plate 907 and the movable screw rod 909, and the limit nut 911 can also be quickly disassembled for the disassembly of structures such as the abutting plate 907, with high operation convenience.
