[0002] Surface scratch detection refers to the process of inspecting and analyzing the surface of a workpiece using specific technologies, methods, and equipment to identify, locate, and assess whether scratch defects exist on the workpiece surface and their severity. This detection process aims to ensure that the surface quality of the workpiece meets relevant standards and requirements and to promptly detect scratch problems that may affect the performance, appearance, or service life of the workpiece.

[0003] Regarding the aforementioned related technologies, the inventors have discovered the following defects: In the prior art, dust may fall on the surface of the workpiece during inspection, which may cause the dust to adhere to the scratches on the workpiece surface, obscuring the true shape and characteristics of the scratches, making it difficult for inspectors to accurately determine the existence of the scratches. At the same time, dust may also form some scratch-like marks on the workpiece surface, interfering with the inspectors' judgment. Utility Model Content

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model includes a motor, a rotating plate, a fixed column, and other components. When the motor is started, the rotating plate drives the fixed column to rotate. During the rotation, the fixed column drives the moving plate to move left and right in a reciprocating motion. The movement of the moving plate drives two moving plates to deliver the gas in the sealed box to the surface of the workpiece through the air outlet, blowing away the dust on the workpiece surface. This effectively avoids the problem of dust falling on the workpiece and affecting the worker's judgment of surface scratches.

[0013] 2. This utility model incorporates components such as limiting holes, limiting posts, and springs. By pulling the limiting post, it disengages from the limiting hole. At this point, the operator can select the angle of illumination by rotating the rotating plate. After selection, the operator can release the limiting post, allowing it to reset under the left and right sides of the spring. The reset limiting post will then enter the limiting hole that matches the selected angle, thus completing the angle adjustment. This allows the device to select a suitable angle to irradiate workpieces of different heights, enhancing the versatility and convenience of the device. Attached Figure Description

[0019] Please see Figure 2 As shown, the inner wall of the slot is in contact with the outer wall of the fixed column 22. The left side of the first movable plate 23 is fixedly connected to the right side of the second movable plate 251. A one-way valve 252 is fixedly connected to the right side of the second movable plate 251. A connecting pipe 26 is fixedly connected to the left side of the sealing box 25.

[0020] Please see Figure 4As shown, a fixed plate 32 is fixedly connected to the left side of the fixed plate 3. A limiting hole 33 is opened on the right side of the fixed plate 32. The inner wall of the limiting hole 33 contacts the limiting post 34. A spring 341 is sleeved on the outer wall of the limiting post 34. A limiting ring 342 is fixedly connected to the side of the outer wall of the limiting post 34 near the spring 341. The setting of the limiting ring 342 can prevent the limiting post 34 from being misaligned or exceeding the range of movement.

[0021] Please see Figure 4 As shown, the right side of the limiting ring 342 is fixedly connected to the left side of the spring 341. The right side of the rotating plate 311 has a moving groove. The inner wall of the moving groove is in contact with the outer wall of the limiting post 34. There are several limiting holes 33, which are arranged in a ring array.

[0022] Please see Figure 2 As shown, the output end of the motor 2 is fixedly connected to a rotating column 21 via a coupling. The back of the rotating column 21 is fixedly connected to the front of the rotating plate 211. The back of the moving plate 23 has a slot, and the top of the moving plate 23 has a sliding groove. The inner wall of the sliding groove contacts a limit block 24. The limit block 24 can prevent the moving plate 23 from being misaligned or offset when it moves.

[0025] The implementation principle of the rough-machined part surface scratch detection device in this application embodiment is as follows: The motor 2 starts, causing the rotating column 21 to drive the rotating plate 211 to rotate. Simultaneously, the rotating plate 211 drives the fixed column 22 to move synchronously. Since the moving plate 23 has a slot on its back, when the fixed column 22 rotates to the left, it causes the moving plate 23 and the moving plate 251 to move to the left. At this time, the one-way valve 252 is closed, causing the moving plate 251 to compress the gas in the sealed box 25, which is then blown out from the air outlet 261 through the connecting pipe 26. Simultaneously, as the moving plate 23 moves to the left, it drives the moving plate 251 on the right side to move to the left. At this time, the one-way valve 252 on the right side is open. The device allows air to enter the sealed box 25 on the right side. With the continuous rotation of the rotating plate 211, dust on the surface of the workpiece is blown away, effectively preventing dust from affecting the worker's judgment of surface scratches. By pulling the limiting post 34, it is disengaged from the limiting hole 33. At this time, the worker can select the angle of illumination by rotating the rotating plate 311. After selection, the worker can release the limiting post 34, which is reset by the left and right sides of the spring 341. The reset limiting post 34 will enter the limiting hole 33 that matches the angle, thus completing the angle adjustment. This allows the device to select a suitable angle to irradiate workpieces of different heights, improving the versatility and convenience of the device.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
