DETAILED DESCRIPTION OF THE INVENTION

[0023] Please refer to Figures 1-5, An automobile part surface roughness detection device, including a processing table 1 and a roughness detector 3. A three-axis moving mechanism 2 and an angle adjustment mechanism 4 are arranged on the top of the processing table 1, and a controller 5 is fixed on the top of the processing table 1;

[0024] The processing table 1 serves as the basic platform of the device, used to carry and fix other components. The roughness detector 3 can move in the X, Y, and Z directions on the processing table 1 through the three-axis moving mechanism 2, so as to perform omnidirectional measurement on automobile parts. The angle adjustment mechanism 4 is used to adjust the angle of the parts to ensure that the roughness detector 3 can measure from different angles. The controller 5 is used to centrally control the movement and detection process of the entire device.

[0025] The angle adjustment mechanism 4 includes an electric rotary table 401, which is fixed on the top of the processing table 1. A bottom plate 402 is fixed on the top of the electric rotary table 401. A first side plate 403 is fixed on the top of the bottom plate 402. A second side plate 404 is arranged above the bottom plate 402. A driving shaft 405 and a driven shaft 408 are rotatably connected to the surfaces of the first side plate 403 and the second side plate 404. A telescopic coupling 406 is fixed between the two driving shafts 405 on both sides. An electric push rod 407 is fixed on the surface of the second side plate 404. One end of the electric push rod 407 is fixedly connected to the surface of the first side plate 403. A clamping plate 409 is fixed on the surface of the driven shaft 408. A driving structure for driving the driving shaft 405 and the driven shaft 408 to rotate is arranged above the bottom plate 402;

[0026] The electric rotary table 401 can rotate 360°, driving the entire angle adjustment mechanism 4 to rotate, thereby adjusting the horizontal angle of the parts. Through the connection of the driving structure, the driving shaft 405 and the driven shaft 408 can achieve synchronous rotation. The electric push rod 407 pushes the second side plate 404 to move, realizing the relative position adjustment of the driving shaft 405 and the driven shaft 408, and then changing the relative position of the clamping plate 409, so as to clamp and fix the automobile parts. In this process, the telescopic coupling 406 can expand and contract and ensure the normal transmission of power. The driving structure drives the driving shaft 405 and the driven shaft 408 to rotate, realizing the multi-angle adjustment of the clamping plate 409 driving the automobile parts, enabling the device to realize the horizontal and tilt angle adjustment of the parts, ensuring that the roughness detector 3 can measure the surface of the parts from different angles, and improving the comprehensiveness and adaptability of the detection.

[0027] Further, the driving structure above the bottom plate 402 includes a frame body 411, which is fixedly connected to the surface of the first side plate 403. A motor 412 is fixed on the surface of the frame body 411. The output shaft of the motor 412 penetrates through the frame body 411 and is fixedly connected to one end of the driving shaft 405. Pulley wheels 410 are fixed on the surfaces of the driving shaft 405 and the driven shaft 408, and the upper and lower pulley wheels 410 are connected by a belt;

[0028] After the motor 412 starts, it drives the driving shaft 405 on one side to rotate through the output shaft. The driving shaft 405 can drive the driving shaft 405 on the other side to rotate synchronously through the cooperation of the expansion coupling 406. The driving shaft 405 can drive the driven shaft 408 to rotate synchronously through the pulley 410 and belt drive, so as to realize the rotational movement of the clamping plate 409, ensuring that the angle adjustment of the parts is flexible and stable.

[0029] Furthermore, embedding grooves 413 are provided on the surfaces of the first side plate 403 and the second side plate 404. A housing 414 and a combined plate 415 are arranged above the first side plate 403. A T-shaped plate 416 is fixed on the surface of the combined plate 415. The T-shaped plate 416 is slidably connected to the inner wall of the housing 414. Both the housing 414 and the combined plate 415 are slidably connected to the surface of the embedding groove 413.

[0030] The housing 414 and the combined plate 415 can be placed inside the embedding grooves 413 with different heights. This enables lighter workpieces to be placed on the surface of the combined plate 415 before clamping, without the need for manual continuous holding of automotive parts before clamping. And the T-shaped plate 416 can move inside the housing 414 to adapt to installation requirements with different widths. After the clamping plate 409 clamps the workpiece, the housing 414 and the combined plate 415 can be pulled out from inside the embedding groove 413 so as not to interfere with the rotation of automotive parts.

[0031] Furthermore, a limiting plate 417 is fixed on the surface of the embedding groove 413. Guide grooves for cooperating with the limiting plate 417 are provided at the bottoms of both the housing 414 and the combined plate 415. The limiting plate 417 is slidably connected to the surface of the guide groove.

[0032] This design enables the limiting plate 417 to enter the guide groove after the housing 414 and the combined plate 415 are placed inside the embedding groove 413, thus avoiding the left-right movement of the housing 414 and the combined plate 415 and preventing them from disengaging from the embedding groove 413 by means of left-right movement.

[0033] Furthermore, two limiting grooves 418 are provided on the inner wall of the housing 414. The T-shaped plate 416 is slidably connected to the surface of the limiting groove 418.

[0034] The T-shaped plate 416 can slide inside the housing 414 and on the surface of the limiting groove 418, which can limit the maximum movement range of the T-shaped plate 416 and prevent the T-shaped plate 416 from disengaging from inside the housing 414.

[0035] Further, the three-axis moving mechanism 2 includes a first linear module 201, a second linear module 203, and a third linear module 204. There are two first linear modules 201, which are fixed to the top of the processing table 1. An activity plate 202 is fixed to the surface of the moving part of the first linear module 201. The second linear module 203 is fixed between the two activity plates 202 on both sides. The third linear module 204 is fixed to the surface of the moving part of the second linear module 203. The roughness detector 3 is fixed to the surface of the moving part of the third linear module 204.

[0036] Through the coordinated movement of multiple linear modules, the roughness detector 3 can move freely in multiple directions, achieving precise positioning of the roughness detector 3 in three-dimensional space and enabling omnidirectional measurement of the surface of parts.

[0037] Further, a first slide rail 419 is fixed to the top of the bottom plate 402. A first slider 420 is slidably connected to the surface of the first slide rail 419. The top of the first slider 420 is fixedly connected to the bottom of the second side plate 404. A second slide rail 421 is fixed to the top of the processing table 1. The second slide rail 421 is designed in a circular ring structure. A second slider 422 is slidably connected to the surface of the second slide rail 421. The top of the second slider 422 is fixedly connected to the bottom of the bottom plate 402.

[0038] The second side plate 404 can drive the first slider 420 to slide on the surface of the first slide rail 419, which helps to improve the accuracy of the movement of the second side plate 404 and can avoid deviation. When the electric rotary table 401 drives the bottom plate 402 to rotate, the second slider 422 will slide on the surface of the second slide rail 421 together with the bottom plate 402, which helps to ensure the stability of the bottom plate 402 during rotation and avoid position deviation or shaking caused by rotation.

[0039] The controller 5 is electrically connected to the first linear module 201, the second linear module 203, the third linear module 204, the roughness detector 3, the electric rotary table 401, the motor 412, and the electric push rod 407.

[0040] Working principle: First, according to the size of the automotive parts, the housing 414 and the combined plate 415 are placed into the corresponding embedding grooves 413. Then, the surfaces of the automotive parts housing 414 and the combined plate 415 are clamped and fixed to the automotive parts by adjusting the distance between the clamping plates 409 on both sides of the electric push rod 407. After that, the housing 414 and the combined plate 415 are taken out. The driving of the active shaft 405 and the driven shaft 408 to rotate by the motor 412 realizes the multi-angle adjustment of the clamping plates 409 driving the automotive parts. At the same time, the electric rotary table 401 can drive the bottom plate 402 to rotate to adjust the horizontal angle of the parts. This design allows the roughness detector 3 to measure the surface of the parts from multiple angles. Combined with the omnidirectional position adjustment of the roughness detector 3 by the three-axis moving mechanism 2, the roughness detector 3 can reach any position on the surface of the parts, avoiding measurement dead angles, improving the efficiency of the entire detection process, and enabling the rapid completion of the comprehensive detection of complex parts.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
