Description

Technical Field

[0001] This disclosure relates to the field of roughness measurement technology, and in particular to a laser detection device for the surface roughness of steel forgings. Background Technology

[0002] After steel forgings are manufactured, surface roughness testing is typically performed to ensure their quality. Appropriate surface roughness improves corrosion resistance, increases adhesion to other materials, and enhances lubricity. Current surface roughness testing methods can be broadly categorized into contact and non-contact methods. However, contact methods can easily scratch the surface, affecting the test results. Non-contact methods usually involve laser monitoring. However, firstly, the surface may have some rust or oxide scale, affecting the accuracy of the results; secondly, the laser is susceptible to vibration and external light sources, causing deviations in the detection process. Furthermore, it's inconvenient to perform laser testing on multiple surfaces simultaneously, impacting work efficiency. Summary of the Invention

[0015] The technical solution provided in this disclosure may include the following beneficial effects: 1. Light-blocking structures are installed on both sides of the outer casing.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 11As shown in the figure, this disclosure proposes a laser detection device for the surface roughness of steel forgings, comprising: a housing 101, on which a first conveyor 102 and a second conveyor 103 are respectively installed on both sides; a light-blocking structure is installed on both sides of the housing 101, the light-blocking structure including a light-shielding baffle 106 fixed to the housing 101, the light-shielding baffle 106 including a first plate 107 and a second plate 108, the first plate 107 and the second plate 108 being elastically connected; an air-blowing structure is installed inside the light-shielding baffle 106, the air-blowing structure including a plurality of air outlets 113 opened on the second plate 108; a first air passage 111 is opened inside the housing 101, the first air passage 111 being connected to the air-blowing structure; and a clamping structure, the clamping structure including two clamping plates 207 installed inside the housing 101, and a first electric cylinder 2 being slidably fitted inside the housing 101. 03. A rotation drive structure is installed between the output end of the first electric cylinder 203 and the clamping plate 207. The rotation drive structure includes a motor 205. A laser measurement structure is also provided, which includes a laser head 310 and a sensor matrix 305. A support frame 304 is slidably fitted inside the housing 101. The support frame 304 is fixedly connected to the sensor matrix 305. A sliding plate 307 is slidably fitted inside the support frame 304. A mounting plate 309 is rotatably fitted on one side of the sliding plate 307. The mounting plate 309 is fixedly connected to the laser head 310. A pressing structure is slidably fitted inside the housing 101. The pressing structure includes a third sliding frame 402 and a pressing frame 403. The pressing frame 403 is in contact with the mounting plate 309. A telescopic rod 404 is installed on the lower side of the third sliding frame 402. A locking structure is installed inside the telescopic rod 404. The locking structure includes a pressing rod 407.

[0022] Specifically, the device is a laser measuring instrument. A steel forging is transported into the housing 101 via a first conveyor 102. During transport, air is blown through the vent 113 to clean the surface of the forging. Then, a first electric cylinder 203 pushes two clamping plates 207 closer together to hold the forging, allowing for transport. When the forging is transported to a fixed position, it is supported by a placement plate 501. The support frame 304 slides downwards, and the mounting plate 309 is slid left and right as needed, adjusting its angle. A control host is installed on the housing 101, controlling the device to operate and reducing labor costs. A laser head 310 emits a laser beam onto the surface of the forging, and a sensor matrix 305 receives the reflected laser beam. The surface roughness of the forging can be measured based on the spot size and offset angle, achieving non-contact laser roughness measurement. This prevents scratches on the forging surface, ensuring accurate test results and improving work efficiency.

[0023] In this embodiment, the outer casing 101 has an inlet 104 and an outlet 105 on both sides, one end of the first conveyor 102 is located inside the inlet 104, one end of the second conveyor 103 is located inside the outlet 105, two light-shielding baffles 106 are located on one side of the inlet 104 and the outlet 105, respectively, the first air passage 111 is connected to the light-shielding baffle 106, and an air pump 114 is fixed on the outer casing 101, the air outlet of the air pump 114 is connected to the first air passage 111.

[0024] Specifically, the steel forgings are transported to the feed inlet 104 by the first conveyor 102, and then clamped and transported by the clamping plate 207. The steel forgings are placed in a fixed position and fixed by the clamping plate 207. At this time, the feed inlet 104 and the discharge outlet 105 are blocked by the light-shielding baffle 106, which can achieve a good light-shielding effect and block other steel forgings to prevent mutual interference between two steel forgings, thus ensuring the accuracy of the device's test results. After the test is completed, the steel forgings are placed on the second conveyor 103 and then transported away by the second conveyor 103, thereby improving the working efficiency of the device.

[0025] The first plate 107 has a first sliding groove 109, which is connected to the first air passage 111. The second plate 108 has a second air passage 112, which is connected to the first air passage 111 and to the air outlet 113. The second air passage 112 is equipped with a first electric valve. Multiple springs 110 are fixed between the second plate 108 and the groove wall of the first sliding groove 109. The first plate 107 has an exhaust port 115 on one side, which is connected to the first sliding groove 109. The exhaust port 115 is equipped with a second electric valve. A sealing gasket is fixed on the periphery of one end of the second plate 108 located in the first sliding groove 109.

[0026] Specifically, when air blowing is required, the air pump 114 is activated, which draws air into the first air passage 111. The air then enters the first sliding groove 109 from the first air passage 111, then enters the second air passage 112, and finally exits from the air outlet 113. This air blowing process, as the steel forging moves during transport, treats the surface of the steel forging, preventing surface rust residue and improving the inspection quality. Furthermore, when the first electric valve is closed, the change in air pressure drives the second plate... The body 108 moves up and down, thereby limiting the steel forging through the second plate 108, which prevents the two steel forgings from affecting each other and ensures the accuracy of the test results. When the air pressure needs to be adjusted, the second electric valve is selectively opened and closed, causing the gas in the first sliding groove 109 to be blown out, thereby reducing the air pressure. Under the action of the spring 110, the second plate 108 is reset, which realizes the up and down sliding of the second plate 108, thereby achieving a better blocking and blowing cleaning effect, improving work efficiency and ensuring the accuracy of the test results.

[0027] Both sides of the outer casing 101 are fixed with a first electric slide rail 201. The output end of the first electric slide rail 201 is fixed with a first sliding frame 202. The first sliding frame 202 is fixedly connected to the first electric cylinder 203. The output end of the first electric cylinder 203 is fixed with a connector 204. The motor 205 is fixed inside the connector 204. A connecting frame 206 is fixed on the clamping plate 207. The connecting frame 206 is fixedly connected to the output end of the motor 205 by bolts. A steel forging 208 is clamped and fixed between the two clamping plates 207.

[0028] Specifically, when clamping a steel forging is required, the first electric slide rail 201 is activated, which transports the clamping plate 207 to the side of the steel forging. Then, the first electric cylinder 203 is activated, bringing the two clamping plates 207 closer together to clamp and fix the steel forging. Activating the first electric slide rail 201 then allows the clamped steel forging to be transported. When it is necessary to measure the flatness of different surfaces of the steel forging, the motor 205 is activated, which drives the clamping plate 207 to rotate, thereby rotating the steel forging between the two clamping plates 207. This achieves a good rotation effect, allowing the steel forging to be flipped. This enables the device to flexibly measure different surfaces of the steel forging, thus expanding the device's applicability and improving its testing efficiency.

[0029] A second electric slide rail 301 is fixed to the top inside the housing 101. A second sliding frame 302 is fixed to the output end of the second electric slide rail 301. A second electric cylinder 303 is fixed on the second sliding frame 302. The output end of the second electric cylinder 303 is fixedly connected to the support frame 304. The sensor matrix 305 includes multiple photoelectric sensors. A second sliding groove 306 is opened in the support frame 304. A sliding plate 307 is located in the second sliding groove 306.

[0030] Specifically, when the positions of the sensor matrix 305 and the laser head 310 need to be adjusted, the second electric slide rail 301 is activated. This allows the second sliding frame 302 to move via the second electric slide rail 301, and the second electric cylinder 303 to move the sensor matrix 305 and the laser head 310 up and down. This allows the height of the sensor matrix 305 and the laser head 310 to be adjusted, making the device suitable for steel forgings of different sizes and expanding its application range. Furthermore, by coordinating the movement of the sensor matrix 305 and the laser head 310 with the movement of the steel forging, the device can measure the roughness of different positions on the steel forging, thereby ensuring the accuracy of the test results, improving work efficiency, and preventing missed measurements.

[0031] A rotating frame 308 is fixed to one side of the sliding plate 307. A rotating shaft 311 is rotatably fitted inside the rotating frame 308. The rotating shaft 311 is fixedly connected to the mounting plate 309. A groove 312 is provided inside the rotating frame 308, and the end of the rotating shaft 311 is located in the groove 312. A third sliding frame 402 is slidably fitted to the lower side of the second sliding frame 302. The sliding of the third sliding frame 402 drives the telescopic rod 404 to slide, so that the telescopic rod 404 drives the sliding plate 307 to slide in the second sliding groove 306 through the rotating frame 308. 2. A third electric slide rail 401 is fixed on the lower side. The output end of the third electric slide rail 401 is fixedly connected to the third sliding frame 402. The telescopic rod 404 includes a first rod body 405 and a second rod body 406. The first rod body 405 is fixedly connected to the third sliding frame 402, the first rod body 405 is slidably connected to the second rod body 406, and the second rod body 406 is fixedly connected to the rotating frame 308. The first rod body 405 and the second rod body 406 are both hollow structures, and the extrusion rod 407 is slidably fitted inside the first rod body 405 and the second rod body 406.

[0032] Specifically, when it is necessary to adjust the distance between the sensor matrix 305 and the laser head 310, the third electric slide rail 401 is activated. This drives the third sliding frame 402 to move, which in turn moves the sliding plate 307. The sliding plate 307 then moves the mounting plate 309, thus adjusting the distance between the laser head 310 and the sensor matrix 305. When the support frame 304 slides upward to a certain extent, the lower pressure frame 403 comes into contact with the mounting plate 309. As the support frame 304 continues to move upward, the lower pressure frame 403 presses the mounting plate 309 downward, causing it to rotate. At this point, the friction between the pressure rod 407 and the rotating shaft 311 is insufficient to fix the rotating shaft 311 when the lower pressure frame 403 presses down. When the support frame 304 moves downward, the friction between the pressure rod 407 and the rotating shaft 311 can fix the mounting plate 309, thus ensuring the stability of the device and improving the accuracy of the detection.

[0033] The end of the rotating shaft 311 is tapered, and friction textures are provided on the periphery of the end of the rotating shaft 311. One end of the extrusion rod 407 is wedge-shaped. The second rod 406 is connected to the groove 312. One end of the extrusion rod 407 is located in the groove 312 and is in contact with the rotating shaft 311. The other end of the extrusion rod 407 is fixed with a piston plate 409. An adsorption block is fixed in the middle of the piston plate 409. An electromagnet 408 is fixed in the third sliding frame 402. The electromagnet 408 is adsorbed and fixed to the adsorption block. An air pipe is installed between the first rod 405 and the first air passage 111. A third electric valve is installed in the first air passage 111.

[0034] Specifically, when the mounting plate 309 is lowered to a certain extent, the third electric valve is opened, allowing air to enter the first rod 405. This pushes the extrusion rod 407 downwards, generating significant friction between the extrusion rod 407 and the rotating shaft 311. This provides a good extrusion and limiting effect, ensuring the stability of the laser head 310 and preventing unstable detection results due to laser head 310 shaking. Furthermore, the electromagnet 408 can attract the adsorption block, pulling the extrusion rod 407 upwards. This removes the restriction on the rotating shaft 311, causing the mounting plate 309 to reset. This allows for arbitrary adjustment of the laser head 310's angle, thus adjusting the laser irradiation angle. This makes the device more flexible to use, ensures the accuracy of detection results, and improves the device's working efficiency.

[0035] A placement plate 501 is slidably fitted inside the bottom of the housing 101. A third electric cylinder 502 is fixed to the bottom of the housing 101. The output end of the third electric cylinder 502 is fixedly connected to the placement plate 501. Multiple sliding rods 503 are fixed to the lower side of the placement plate 501. The sliding rods 503 are slidably connected to the housing 101.

[0036] Specifically, when measuring the steel forging 208, the third electric cylinder 502 is activated, which drives the placement plate 501 to move upward until the placement plate 501 contacts the steel forging. At this time, the placement plate 501 can support the steel forging, thereby ensuring the stability of the steel forging. After support, the clamping of the steel forging is stopped, and the height of the steel forging can be adjusted by sliding the placement plate 501 up and down, making the device more flexible to use.

[0037] The second plate 108 has a slot. When the third sliding frame 402 slides and drives the telescopic rod 404 to slide, the telescopic rod 404 drives the sliding plate 307 to move, thereby driving the mounting plate 309 into the slot. At this time, the mounting plate 309 can slide up and down to drive the second plate 108 to move up and down synchronously.

[0038] Specifically, when clamping a steel forging, the mounting plate 309 is slid to one side of the steel forging 208. The mounting plate 309 limits the position of the steel forging 208, ensuring its stability and allowing the device to effectively clamp the steel forging. Alternatively, the mounting plate 309 can be inserted into the slot, and its up-and-down movement will cause the second plate 108 to move up and down synchronously, thus providing functions such as light shielding. This can be flexibly adjusted in conjunction with air pressure. By installing a camera or distance sensor inside the housing 101, the position and angle of the second plate 108 and the mounting plate 309 can be monitored in real time, thereby improving the accuracy of displacement.

[0039] Workflow: The steel forging is transported to the feed inlet 104 via the first conveyor 102. The air pump 114 is activated, drawing air into the first air passage 111. The air then enters the first sliding groove 109, then the second air passage 112, and finally exits through the air outlet 113. This air blowing process, as the steel forging moves, treats its surface, preventing surface rust residue and improving inspection quality. The first electric slide rail 201 is activated, moving the clamping plate 207 to the side of the steel forging. The first electric cylinder 203 then moves the two clamping plates 207 closer together, clamping and securing the steel forging. Activating the first electric slide rail 201 allows for the transport of the clamped steel forging. When it is necessary to measure the flatness of different surfaces of the steel forging, activating the motor 205 drives the clamping plate 207 to rotate, thereby rotating the steel forging between the two clamping plates 207, achieving a better rotation effect. Activating the second electric slide rail 301 moves the second sliding frame 302, and the second electric cylinder 303 moves the sensor matrix 305 and laser head 310 up and down, allowing for height adjustment of the sensor matrix 305 and laser head 310. This makes the device suitable for steel forgings of different sizes, expanding its applicability. Furthermore, the movement of the sensor matrix 305 and laser head 310 can be adjusted... The movement of the moving steel forging allows the device to measure the roughness of different positions on the forging. When the distance between the sensor matrix 305 and the laser head 310 needs to be adjusted, the third electric slide rail 401 is activated. This drives the third sliding frame 402 to move, which in turn moves the sliding plate 307. The sliding plate 307 then moves the mounting plate 309, thus adjusting the distance between the laser head 310 and the sensor matrix 305. After the support frame 304 slides upward to a certain extent, the lower pressure frame 403 contacts the mounting plate 309. As the support frame 304 continues to move upward, the lower pressure frame 403 presses the mounting plate 309 downward, causing the mounting plate 309 to rotate. At this point, the friction between the extrusion rod 407 and the rotating shaft 311 is insufficient to fix the rotating shaft 311 when the lower pressure frame 403 presses down. When the support frame 304 moves downward, the friction between the extrusion rod 407 and the rotating shaft 311 can fix the mounting plate 309. When the mounting plate 309 moves downward to a certain extent, the third electric valve is opened, allowing air to pass into the first rod body 405, thereby pushing the extrusion rod 407 to move downward relatively. The extrusion rod 407 generates greater friction with the rotating shaft 311, thus achieving a better extrusion and limiting effect, ensuring the stability of the laser head 310, preventing the laser head 310 from shaking and causing unstable detection results. Furthermore, the extrusion rod 407 can be pulled upward relatively by attracting the adsorption block through the electromagnet 408.This removes the restriction on the rotating shaft 311, causing the mounting plate 309 to reset. This allows for arbitrary adjustment of the laser head 310's angle, thus adjusting the laser irradiation angle. When measuring the steel forging 208, activating the third electric cylinder 502 moves the placement plate 501 upwards until it contacts the steel forging. At this point, the placement plate 501 supports the steel forging, ensuring its stability. After support, stopping the clamping of the steel forging allows for adjustment of its height by sliding the placement plate 501 up and down, making the device more flexible to use.
