[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Example: Figures 1-3 and Figure 5As shown, this embodiment proposes an optical rapid detection device for the surface roughness of a ring, including a detection seat 1, a ring body 2, a detector 3, an adjustment component 4, and a rotation component 5. An adjustment component 4 for adjusting the detection position of the detector 3 is fixedly installed on the top of the detection base 1. A rotating component 5 for assisting the detector 3 in detection is fixedly installed on the top of the detection base 1. The rotating component 5 is located in front of the adjustment component 4. The adjustment assembly 4 includes a detection frame 401, a first motor 402, a lead screw 403, a positioning block 405, a telescopic cylinder 406, and a telescopic rod 407; The test frame 401 is bolted to the top of the test base 1; The top of the testing frame 401 is bolted with a first motor 402; A lead screw 403 is installed at the output end of the first motor 402; A positioning block 405 is slidably mounted on the lead screw 403 via a slider; A telescopic cylinder 406 is installed through the positioning block 405; One end of the telescopic cylinder 406 is fitted with a telescopic rod 407; The other end of the telescopic rod 407 is bolted with a mounting base 6; A servo motor 7 is bolted to the right side of the mounting base 6; A screw 8 is mounted on the output end of the servo motor 7; the screw 8 is bolted to the detector 3 via a vertical plate. When the detection position of the detector 3 needs to be adjusted, the first motor 402 is started, which drives the lead screw 403 to rotate. When the lead screw 403 rotates, the positioning block 405 moves along the direction of the lead screw 403, thereby adjusting the height of the detector 3. The telescopic cylinder 406 controls the extension and retraction of the telescopic rod 407, thereby achieving precise adjustment of the detector 3's position in the horizontal and vertical directions.

[0020] like Figures 1-3 and Figure 5 As shown, the rotating assembly 5 includes a second motor 501, a rotating shaft 502, and a detection plate 503; The second motor 501 is bolted to the bottom of the detection seat 1; The output end of the second motor 501 is fitted with a rotating shaft 502; A detection plate 503 is bolted to the top of the rotating shaft 502; The ring body 2 is located on top of the detection plate 503. The second motor 501 is started, which drives the rotating shaft 502 to rotate. The rotation of the rotating shaft 502 in turn drives the detection plate 503 to rotate. Since the ring body 2 is located on top of the detection plate 503, the rotation of the detection plate 503 will drive the ring body 2 placed on it to rotate at a constant speed, so that each part of the ring surface passes under the detector 3 in sequence, realizing full circumferential and continuous detection coverage of the ring circumference.

[0021] like Figures 1-3 As shown, the inspection instrument 3 is located on the rear side of the ring body 2. When it is necessary to inspect the surface of the ring body 2, the servo motor 7 is started to drive the screw 8 to rotate, which in turn drives the vertical plate to rotate synchronously. While the vertical plate rotates, the inspection instrument 3 also rotates, so that the measuring port of the inspection instrument 3 is precisely aligned with the top surface of the ring body 2 to perform roughness inspection. This significantly improves the accuracy and flexibility of the inspection, effectively meets the needs of roughness inspection of different parts of the ring surface, and ensures the accuracy and reliability of the inspection results.

[0022] like Figures 1-5 As shown, a column 9 is bolted to the top of the detection plate 503, and the column 9 is located inside the ring body 2. Electric push rods 10 are provided on both sides of the column 9. The column 9 is fixed to the center of the detection plate 503 and extends into the inner hole of the ring. The electric push rods 10 on both sides can extend and retract radially synchronously or independently, which can support and initially center the ring from the inside, limiting the possible displacement of the ring during rotation, providing a basis for subsequent precise positioning, and ensuring the stability of the ring during the detection process.

[0023] like Figures 1-5 As shown, a spring 11 is bolted to one end of the electric push rod 10 facing the inner wall of the ring body 2, and a damper 12 is fixedly connected to the other end of the spring 11. A positioning plate 13 is fixedly connected to the other end of the damper 12. The end of the electric push rod 10 is connected to the damper 12 through the spring 11, and finally contacts the inner wall of the ring through the arc-shaped positioning plate 13. The spring 11 provides a flexible clamping force to avoid damage to the ring from rigid contact; the damper 12 effectively absorbs the small vibrations that may be generated during the rotation of the ring. The combination of the two achieves stable clamping and positioning while also having buffering and vibration reduction functions, providing a more stable working condition for optical inspection.

[0024] like Figures 1-5 As shown, the outer contour of the positioning plate 13 is arc-shaped, and the arc-shaped contour is adapted to the inner wall of the ring body 2. The arc-shaped design increases the contact area between the positioning plate 13 and the inner wall of the ring, making the clamping force distribution more uniform and further enhancing the clamping stability. At the same time, it avoids the deformation or surface damage of the ring that may be caused by local stress concentration, and is especially suitable for thin-walled or precision rings.

[0025] like Figures 1-5As shown, a rectangular plate 14 is bolted to the top of the detection seat 1, and the rotating shaft 502 passes through the rectangular plate 14. The rectangular plate 14 provides an additional intermediate support point for the rotating shaft 502, which effectively increases the rigidity of the rotating shaft 502 during rotation and reduces the deflection deformation and radial runout that may occur under high-speed rotation, thereby ensuring the stability and concentricity of the ring's rotation trajectory and providing a basic guarantee for high-precision detection.

[0026] like Figure 4 and Figure 5 As shown, a scale 15 is provided on the top of the rectangular plate 14, and the scale 15 is located on the outside of the rotating shaft 502. The scale 15 allows the operator to intuitively and quickly observe or manually calibrate the initial angular position or deflection angle of the ring or detection plate 503, which is convenient for locating the detection starting point or for position reference during fault diagnosis, thus enhancing the ease of operation and maintainability of the device.

[0027] Working Principle: This utility model provides a rapid optical detection device for the surface roughness of a ring. The specific steps are as follows: Step 1: Place the ring body 2 on the detection plate 503. The electric push rods 10 on both sides can extend and retract radially synchronously or independently, supporting and initially centering the ring from within, limiting possible displacement of the ring during rotation, providing a foundation for subsequent precise positioning, and ensuring the stability of the ring during detection. Step 2: When it is necessary to adjust the detection position of the detector 3, start the first motor 402. The first motor 402 drives the lead screw 403 to rotate. When the lead screw 403 rotates, it causes the positioning block 405 to move along... The lead screw 403 moves in a certain direction to adjust the height of the detector 3. The telescopic cylinder 406 controls the extension and retraction of the telescopic rod 407, thereby achieving precise adjustment of the detector 3 in the horizontal and vertical directions. Step 3: Start the second motor 501. The second motor 501 drives the rotating shaft 502 to rotate. The rotation of the rotating shaft 502 drives the detection plate 503 to rotate. Since the ring body 2 is located on top of the detection plate 503, the rotation of the detection plate 503 will drive the ring body 2 placed on it to rotate at a constant speed, so that each part of the ring surface passes under the detector 3 in sequence, realizing full circumferential and continuous detection coverage of the ring circumference.
