[0002] In the field of automotive track chain maintenance and inspection, ensuring the integrity and safety of the track chain is of vital importance.
[0003] There are several methods for chain flaw detection in practical applications:
[0004] Magnetic particle inspection: When a workpiece made of ferromagnetic material is magnetized, if there are defects such as cracks on the surface of the workpiece, the magnetic lines of force will be distorted and escape from the surface of the workpiece to form a leakage magnetic field, thereby showing the location, shape and size of the defect;
[0005] Penetrant testing: using the penetration effect of liquid, a penetrant containing dye or fluorescent agent is applied to the surface of the chain, allowing it to penetrate into defects such as cracks on the surface;
[0006] Ultrasonic flaw detection: When ultrasonic waves propagate in a workpiece, they will reflect or refract when they encounter interfaces between different media (such as interfaces between defects such as cracks and the workpiece matrix). By analyzing the time and amplitude of the reflected waves, the location and size of the defects can be determined.
[0007] However, the method of penetrant testing often relies on manual operation and requires frequent adjustment of the chain position, which is not only time-consuming and labor-intensive, but also inefficient and difficult to meet the needs of large-scale testing.

The steps of cleaning the chain and treating the penetrant liquid are relatively cumbersome, resulting in a complex technical problem in the detection process. The overall idea is as follows:
[0025] In view of the problems existing in the prior art, the utility model provides a chain surface crack detection device, including a device bracket 33, a liquid placement box 31 for placing cleaning liquid or fluorescent liquid is fixedly installed at the front end of the device bracket 33, a rectangular groove is opened in the liquid placement box 31, and a drain port 32 is provided at the side end of the liquid placement box 31.

[0028] A limit strip 23 is fixedly installed on the circumferential surface of the second rotating shaft 19, and a cleaning roller 24 is sleeved on the second rotating shaft 19 and the limit strip 23. A locking screw 25 is provided at the front end of the second rotating shaft 19, and the cleaning roller 24 is fixedly installed on the second rotating shaft 19 through the locking screw 25. The cleaning roller 24 and the second rotating shaft 19 are connected through the locking screw 25, so that when the cleaning roller 24 needs to be disassembled, the locking screw 25 can be disassembled very quickly, and then the cleaning roller 24 can be replaced.
[0029] A threaded rod 21 is fixedly installed on the side end of the limiting circular plate 22, and the threaded rod 21 is installed on the side end of the device bracket 33 through a thread. The setting of the threaded rod 21 allows the user to adjust the moving block 18 by rotating the threaded rod 21, and the limiting circular plate 22 is sleeved in the moving block 18 and will only rotate in the moving block 18 and will not move left or right.
[0030] A moving plate 12 is slidably installed at the rear end of the device bracket 33, and a servo motor 11 is fixedly installed on the moving plate 12. The servo motor 11 is fixedly connected to the first rotating shaft 15 through an output shaft, and a transmission sprocket 16 is fixedly installed at the front end of the first rotating shaft 15. The servo motor 11 is directly connected to the transmission sprocket 16 through the first rotating shaft 15, so that the servo motor 11 can directly participate in the rotation of the transmission sprocket 16, directly drive the chain to perform rotation detection, and reduce power loss.
[0031] A rotating bearing 34 is provided at the front end of the device bracket 33 , and a crawler chain 35 is sleeved between the transmission sprocket 16 and the rotating bearing 34 .
[0032] Working principle:
[0033] In the first step, the device uses a penetrant flaw detection method when performing flaw detection on the track chain 35 on the car track. The principle is to use the penetration effect of liquid to apply a penetrant containing a dye or fluorescent agent on the surface of the track chain 35 so that it penetrates into the cracks and other defects on the surface. After a certain period of time, the excess penetrant is removed and then a developer is applied. The developer will absorb and display the penetrant remaining in the defect, thereby presenting the defect. The user sets the track chain 35 on the drive sprocket 16 and the rotating bearing 34, and then the gear on the servo motor 11 The teeth are aligned with the holes on the track chain 35, and then the threaded rod 21 is rotated to move the limiting circular plate 22 on the threaded rod 21, and the limiting circular plate 22 will drive the moving block 18 to move, and at this time the moving block 18 will drive the first rotating shaft 15 and the transmission sprocket 16 to move, so that the track chain 35 can be tightened, and the servo motor 11 and the moving plate 12 at the rear end of the first rotating shaft 15 will also move together, and the moving plate 12 is limited and slidably installed in the device bracket 33 (the moving plate 12 is T-shaped and slidably installed in the T-slot in the device bracket 33).
[0034] In the second step, the user first adds cleaning liquid into the rectangular groove of the liquid placement box 31, replaces the cleaning roller 24 (the cleaning roller 24 has various styles, for example, a brush is provided on its surface, or a wiping cloth is provided on its surface) with a style with a brush, and then the user controls the servo motor 11 to work, so that the servo motor 11 drives the first rotating shaft 15 to rotate through the output shaft, and at this time the first rotating shaft 15 will drive the transmission sprocket 16 to rotate, and the transmission sprocket 16 will drive the crawler chain 35 to circulate and rotate in the cleaning liquid in the liquid placement box 31, and when the first rotating shaft 15 rotates, the first sprocket 13 on its surface will drive the connecting chain 14 to rotate, and the connecting chain 14 will drive the second sprocket 17 to rotate, and at this time the second rotating shaft 19 will rotate, and the rotation of the second rotating shaft 19 The movement will drive the cleaning roller 24 to rotate, and the crawler chain 35 is scrubbed and cleaned. After cleaning, the cleaning liquid in the liquid placement box 31 is discharged through the drain port 32 (a switch is provided on the drain port 32), and then a penetrant containing a dye or a fluorescent agent is added. The operation is repeated at this time, so that the penetrant penetrates into the crawler chain 35. The first rotating shaft 15 and the transmission sprocket 16 are set, and the rotatable bearing 34 is set on the device bracket 33. When the crawler chain 35 on the aluminum crawler track of the automobile is subjected to flaw detection, it can automatically rotate so that the chain can be continuously flaw-detected, without the need for frequent manual adjustment of the position or posture of the chain, which greatly saves the detection time. Especially for large-scale chain detection tasks, this continuous operation mode can significantly improve the speed and efficiency of detection.
[0035] The third step is to release the penetrant liquid, add cleaning liquid, clean the cleaning liquid on the surface of the crawler chain 35, remove the locking screw 25 at the same time, replace the cleaning roller 24 with a style with a wiping cloth, and then install it. At this time, the cleaning roller 24 can wipe the surface of the crawler chain 35, wipe off the excess penetrant on the surface of the crawler chain 35, and then apply the developer. After the developer is dry, observe the chain surface under normal light (for colored penetrant liquid) or ultraviolet light (for fluorescent penetrant liquid) to see if there are any traces of defects. The cleaning roller 24 set by the new device allows the device to clean, wipe, and other operations on the crawler chain 35 while rotating the crawler chain 35, thereby simplifying the steps in the chain flaw detection process and effectively improving the efficiency of chain flaw detection. In addition, the cleaning roller 24 can be replaced according to different operations, which improves the diversity of the use of the equipment and saves the cost of the equipment.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
