Description

Technical Field

[0001] This invention relates to the field of mechanical testing technology, specifically to a high-speed guide wheel dynamic amplitude laser testing device. Background Technology

[0002] In the steel rolling process of industries such as iron and steel and metallurgy, high-speed guide rollers play a crucial role in guiding and supporting the rolled workpiece, and their working condition directly affects the quality of the workpiece and production efficiency. During high-speed rotation, the guide rollers generate dynamic amplitude. If the amplitude is too large, it can lead to workpiece deviation, increased vibration, and even equipment damage and production accidents. Therefore, accurate detection of the dynamic amplitude of high-speed guide rollers is essential.

[0003] In the prior art, such as Chinese Patent Publication No. CN117600925A, a method and apparatus for controlling amplitude stability in ultrasonic-assisted processing of hard and brittle materials are disclosed. The apparatus includes a processing device comprising a transducer, an amplitude transformer, and a processing tool; an ultrasonic amplitude detection feedback system including a high-speed response laser displacement sensor, whose measured ultrasonic amplitude data is processed and analyzed by a high-speed response computer, converting the amplitude attenuation into an ultrasonic power increment, and transmitting the signal to a high-speed response ultrasonic power supply to compensate for the amplitude attenuation under load, thus achieving a constant ultrasonic amplitude output during processing; and an acoustic emission sensor amplitude measurement device including an acoustic emission sensor, which transmits data to a high-speed response computer in real time to verify whether the amplitude output by the ultrasonic amplitude detection feedback system is constant. This invention solves the problem of amplitude attenuation under force load during existing ultrasonic-assisted processing of hard and brittle materials, enabling stable amplitude ultrasonic processing experiments.

[0004] In existing technologies, commonly used methods for detecting the dynamic amplitude of guide wheels are mainly divided into two categories: contact detection and non-contact detection. Contact detection methods, such as those using dial indicators or displacement sensors, require direct contact between the detection device and the guide wheel. This not only interferes with the normal operation of the guide wheel but also easily causes wear and damage to the detection device under high-speed rotation, making it difficult to guarantee detection accuracy. Non-contact detection methods, such as ultrasonic detection and infrared detection, avoid direct contact with the guide wheel, but suffer from low detection accuracy and susceptibility to environmental interference, making it difficult to meet the high-precision detection requirements of dynamic amplitude of high-speed guide wheels.

[0005] Therefore, we propose a high-speed guide wheel dynamic amplitude laser detection device to solve the problems mentioned in the background art. Summary of the Invention

[0006] The purpose of this invention is to provide a laser detection device for the dynamic amplitude of a high-speed guide wheel, addressing the aforementioned issues. Common methods for detecting the dynamic amplitude of guide wheels in the background art mainly fall into two categories: contact detection and non-contact detection. Contact detection methods, such as those using dial indicators or displacement sensors, require direct contact between the detection device and the guide wheel. This not only interferes with the normal operation of the guide wheel but also easily causes wear and damage to the detection device under high-speed rotation, making it difficult to guarantee detection accuracy. Non-contact detection methods, such as ultrasonic detection and infrared detection, while avoiding direct contact with the guide wheel, suffer from low detection accuracy and susceptibility to environmental interference, failing to meet the high-precision detection requirements for the dynamic amplitude of high-speed guide wheels.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When used, this invention achieves multi-dimensional technological breakthroughs through the coordinated operation of various mechanical components, effectively solving the pain points of existing detection technologies. The linkage between the laser detection module and the mounting base, sleeve assembly, and other structures, along with the installation holes, ensures the stable fixation of the device. The screwing connection between the threaded joint and the sleeve assembly ensures the precise positioning of the laser detection module, allowing the laser beam to stably irradiate the surface of the guide wheel assembly. This avoids interference from contact detection on the operation of the guide wheel. At the same time, the non-contact laser detection method reduces wear on the detection device under high-speed rotation, ensuring the stability and continuity of the detection process from a structural perspective and significantly improving the reliability of the detection.

[0018] 2. In use, this invention forms a highly efficient cleaning mechanism through the linkage of the scraper assembly with components such as the servo push rod, connecting arm, and guide push rod. The servo push rod drives the moving assembly and connecting arm to adjust their longitudinal position, while the guide push rod pushes the displacement assembly to move laterally. In conjunction with the servo motor driving the bevel gear transmission, the scraper assembly rotates. The working range of the scraper can be flexibly adjusted according to the position of the guide wheel assembly, promptly removing impurities from the surface of the guide wheel and preventing impurities from affecting the laser reflection accuracy. This linkage design allows the cleaning operation and the detection process to be carried out in tandem, reducing the interference of environmental factors on the detection results from the source and further improving the accuracy of dynamic amplitude detection.

[0019] 3. In use, this invention establishes an adaptive height adjustment system through the linkage of the guide rod mechanism with components such as the adjusting push rod, sleeve assembly, and support. The adjusting push rod pushes the first piston plate to compress gas, which in turn drives the second piston plate and guide rod mechanism to rise and fall through the air pressure transmission. Combined with the limiting and fixing of the nut assembly, the height of the guide wheel assembly is precisely adjusted to meet the requirements of different specifications of rolled steel parts. At the same time, the linkage between the air pressure sensor and the display assembly can monitor the air pressure changes in real time during the adjustment process, ensuring that the guide wheel assembly is always in a stable support state. This linkage design not only expands the applicability of the device, but also ensures the consistency of the detection data through a stable support environment, allowing the device to maintain high-efficiency detection performance in complex rolling mill scenarios.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-8As shown, the present invention provides a technical solution: a high-speed guide wheel dynamic amplitude laser detection device, including a mounting base 1, a sleeve assembly 1011 fixedly connected to the center of the top surface of the mounting base 1, an internal thread is provided on the inner wall of the sleeve assembly 1011, and through holes are provided in a ring array on the outer circumferential surface of the sleeve assembly 1011. The through holes are wire holes 1012, and a threaded joint 1013 is screwed into the inside of the sleeve assembly 1011. An end cap assembly 1015 is fixedly connected to the top surface of the threaded joint 1013. A laser detection module 1016 is fixedly connected to the top surface of the end cap assembly 1015, and a wiring assembly 1014 is fixedly connected to the bottom end of the threaded connector 1013. The wiring assembly 1014 is led out through the wire hole 1012. A guide bracket 2 is fixedly connected to the top surface of the mounting base 1. There are two guide brackets 2, which are arranged in a longitudinal array and fixedly connected to the front and rear sides of the top surface of the mounting base 1. Both guide brackets 2 have longitudinal grooves inside, and an adjusting push rod 5 is fixedly connected inside the longitudinal grooves. A sleeve assembly 501 is also fixedly connected inside the longitudinal grooves. The sleeve assembly 501 has a hollow internal structure. A first piston plate 5011 is installed on the inner side of the sleeve assembly 501. A first sealing ring 5012 is fixedly connected to the outer circumferential surface of the first piston plate 5011. A through hole is opened at the bottom end of the sleeve assembly 501. The through hole is used to adjust the top end of the push rod 5. The outlet passes through, and the top of the adjusting push rod 5 is connected to the bottom of the first piston plate 5011. The mounting base 1 has four mounting holes 101 inside, which are respectively located at the four corners inside the mounting base 1. The left and right sides of the guide bracket 2 are provided with longitudinally arranged guide grooves 201. The guide grooves 201 are fixedly connected to the inside of the guide grooves 201. The servo push rod 2011 is arranged longitudinally, and the top of the servo push rod 2011 is fixedly connected to the moving component 2012. The outer side of the moving component 2012 is fixedly connected to the slider component 2013. The outer side of each moving component 2012 is fixedly connected to two slider components 2013 with protruding structures. The side of the moving component 2012 away from the guide bracket 2 is fixedly connected to the connecting arm 3. The outer side of the support 7 is fixedly connected to two limiting blocks 701 with opposing structures.

[0023] In this embodiment, during use, firstly, using the four mounting holes 101 at the four corners of the mounting base 1, the entire device is securely installed at the corresponding station of the steel rolling production line using bolts and other fasteners to ensure that the device will not shift or shake when the steel rolling piece 7014 passes through at high speed. Then, the threaded connector 1013 is screwed into the internal thread of the sleeve assembly 1011. The threaded engagement achieves precise positioning of the end cap assembly 1015, thereby placing the laser detection module 1016 fixed on the top surface of the end cap assembly 1015 in the preset detection position. The wiring assembly 1014 at the bottom of the threaded connector 1013 passes through the wire holes 1012 opened in the annular array on the outer circumference of the sleeve assembly 1011 to complete the circuit connection between the laser detection module 1016 and the external control system, including the power supply line and the data transmission line. When steel rolling production begins, the guide wheel assembly 7013 rotates at high speed driven by the steel rolling piece 7014. The laser detection module 1016 is activated and emits a laser beam of a specific wavelength. The laser beam accurately illuminates the outer circumferential surface of the guide wheel assembly 7013. As the guide wheel assembly 7013 generates dynamic amplitude during high-speed rotation, the position of each point on its surface will change slightly periodically with the amplitude. This causes the path of the laser beam reflected back to the laser detection module 1016 to change accordingly. The photoelectric sensor inside the laser detection module 1016 captures the change in the reflected light and converts the light signal into an electrical signal, which is then transmitted to the external control system through the wiring assembly 1014. The external control system analyzes and processes the received electrical signals, calculates the displacement of the guide wheel assembly 7013 at different times based on the change in the reflection path of the laser beam, and then obtains key parameters such as the value of dynamic amplitude and frequency, which are displayed in real time on the supporting terminal equipment. Throughout the detection process, the laser detection module 1016 and the guide wheel assembly 7013 remain in a non-contact state and will not cause any mechanical interference to the normal rotation of the guide wheel assembly 7013. This embodiment completely solves the problem of interference with the guide wheel's operation caused by direct contact between dial indicators, displacement sensors, and other components and the guide wheel in existing contact detection methods. At the same time, it avoids wear and damage to the detection device caused by contact friction in high-speed rotation environments, fundamentally ensuring the continuity of the detection process and the stability of detection accuracy, and meeting the basic requirements for high-precision detection of the dynamic amplitude of high-speed guide wheels.

[0024] Example 2: Figures 1-5As shown, there are four connecting arms 3, with each pair of longitudinally adjacent connecting arms 3 forming a group. The two groups of connecting arms 3 are arranged opposite each other. Each group of connecting arms 3 has a transverse groove inside, and a guide push rod 301 is installed inside the groove. A displacement component 3011 is fixedly connected to the side of the guide push rod 301 away from the connecting arm 3. A guide slider 3012 is fixedly connected to the outside of the displacement component 3011. The guide slider 3012 protrudes from the displacement component 3011. The displacement component 3011 is slidably connected to the connecting arm 3 through the guide slider 3012. Each pair of longitudinally adjacent displacement components 3011 forms a group. The inner side of the displacement component 3011 is also rotatably connected to a rotating shaft mechanism 4. The front end of the rotating shaft mechanism 4 is coaxially fixedly connected to a bevel gear A401. The side of the displacement component 3011 away from the connecting support arm 3 is also fixedly connected to a side plate assembly 4011. A servo motor 4012 is fixedly connected to the top surface of the side plate assembly 4011. The bottom end of the servo motor 4012 is provided with an output shaft. The output shaft is connected to the side plate assembly 4011 through a bearing seat. A bevel gear B4013 is installed on the bottom output shaft of the servo motor 4012. The bevel gear B4013 meshes with the bevel gear A401 for transmission. The outer side of the rotating shaft mechanism 4 is fixedly connected to a scraper assembly 4014.

[0025] In this embodiment, during use, before or during laser detection, when impurities such as oxide scale and iron filings adhere to the surface of the guide wheel assembly 7013, a cleaning mechanism is activated. First, the servo push rod 2011 in the guide groove 201 longitudinally opened on the left and right sides of the guide bracket 2 receives a control signal, and the output shaft of the servo push rod 2011 extends and retracts, driving the moving component 2012 fixedly connected to its top to move longitudinally along the guide groove 201. The slider assembly 2013 with two protruding structures fixedly connected to the outside of the moving component 2012 is embedded in the groove of the inner wall of the guide groove 201, ensuring that the moving component 2012 will not deviate or shake during the movement, thereby driving the connecting arm 3 fixedly connected to the side of the moving component 2012 away from the guide bracket 2 to adjust its longitudinal position synchronously, so that the connecting arm 3 is aligned with the axial range of the guide wheel assembly 7013. The guide push rod 301 in the transverse groove inside the connecting arm 3 is activated, and its output end pushes the displacement component 3011 to move along the transverse groove. The guide slider 3012 fixedly connected to the outside of the displacement component 3011 is embedded in the side wall groove of the transverse groove to ensure the smoothness and accuracy of the transverse movement of the displacement component 3011. Through the precise extension and retraction of the guide push rod 301, the transverse position of the displacement component 3011 is adjusted so that the rotating shaft mechanism 4 rotatably connected to the inside of the displacement component 3011 and the scraper assembly 4014 fixed to its outside are close to the outer circumferential surface of the guide wheel assembly 7013 and maintain a suitable cleaning gap. The servo motor 4012 at the top of the side plate assembly 4011, which is fixedly connected to the side away from the connecting arm 3, is started. The bottom output shaft of the servo motor 4012 is stably supported on the side plate assembly 4011 through the bearing seat. The output shaft drives the bevel gear B4013 installed on it to rotate. Since the bevel gear B4013 meshes with the bevel gear A401, which is coaxially fixedly connected to the front end of the rotating shaft mechanism 4, the rotation of the bevel gear B4013 drives the bevel gear A401 and the rotating shaft mechanism 4 to rotate synchronously. This causes the scraper assembly 4014, which is fixed on the outside of the rotating shaft mechanism 4, to rotate around the rotating shaft mechanism 4. The edge of the scraper assembly 4014 contacts the surface of the guide wheel assembly 7013, and scrapes off the impurities on the surface during the rotation. During the cleaning process, the servo push rod 2011 and the guide push rod 301 can finely adjust the position and cleaning force of the scraper assembly 4014 in real time according to the rotation speed and amplitude changes of the guide wheel assembly 7013. This ensures that impurities are efficiently removed without affecting the normal operation of the guide wheel assembly 7013. The surface of the cleaned guide wheel assembly 7013 can reflect the laser beam more stably, avoiding interference from impurities on the laser reflection path. This solves the problem of low detection accuracy caused by environmental impurities in existing non-contact detection methods, making the amplitude data obtained by the laser detection module 1016 more accurate and reliable.

[0026] Example 3: Figures 3-6As shown, a display component 5013 is fixedly connected to the front end of the outer periphery of the sleeve assembly 501. A pressure sensor 5014 is fixedly connected to the rear side of the display component 5013. The pressure sensor 5014 is located inside the sleeve assembly 501 and is used to detect the gas pressure in the sleeve assembly 501. A guide rod mechanism 6 is inserted inside the sleeve assembly 501. The main body of the guide rod mechanism 6 is a cylindrical structure, and the guide rod mechanism 6 passes through the sleeve assembly 501 upwards. A second piston plate 601 is fixedly connected to the bottom end face of the guide rod mechanism 6, and a second sealing ring 6011 is also fixedly connected to the outer periphery of the second piston plate 601. The second piston plate 601 and the first piston plate 5011 together form a compression structure for the gas in the sleeve assembly 501. A baffle assembly 6012 is fixedly connected to the outer periphery of the guide rod mechanism 6. The main body of the baffle assembly 6012 is a cylindrical structure, and the baffle assembly 6012 is cylindrical. The diameter is larger than that of the guide rod mechanism 6. The top of the outer peripheral surface of the guide rod mechanism 6 is also provided with an external thread. A nut assembly 6013 is screwed onto the outer side of the external thread. A mounting support 7 is installed inside the longitudinal sliding groove opened at the front end of the guide bracket 2. The mounting support 7 is sleeved on the outer side of the guide rod mechanism 6 and is located above the baffle assembly 6012. The mounting support 7 is limited by the nut assembly 6013. There are two mounting supports 7. The inner side of the two mounting supports 7 is also fixedly connected to the mounting plate 7011. The mounting plate 7011 and the mounting support 7 are provided with through holes. A guide shaft assembly 7012 is inserted into the through hole. The guide shaft assembly 7012 is provided with through holes that match the guide rod mechanism 6. There are two guide shaft assemblies 7012. The inner side of the two guide shaft assemblies 7012 is rotatably connected to the guide wheel assembly 7013. A rolled steel piece 7014 passes through the outer side of the guide wheel assembly 7013.

[0027] In this embodiment, when it is necessary to adapt to rolled steel parts 7014 of different specifications during use, the height adjustment system is activated. The adjustment push rod 5 fixed in the longitudinal groove inside the guide bracket 2 receives the control signal, and its top output end extends upward through the through hole at the bottom of the sleeve assembly 501, pushing the first piston plate 5011 inside the sleeve assembly 501 to move upward. The first sealing ring 5012 fixed on the outer circumferential surface of the first piston plate 5011 is tightly fitted with the inner wall of the sleeve assembly 501, ensuring that the space inside the sleeve assembly 501 separated by the first piston plate 5011 has good airtightness. As the first piston plate 5011 rises, the gas above it is compressed, and the air pressure gradually increases. The compressed gas inside the sleeve assembly 501 transmits pressure to the second piston plate 601 fixedly connected to the bottom of the guide rod mechanism 6. The second sealing ring 6011 on the outer circumference of the second piston plate 601 also ensures the effective transmission of gas pressure. Under the action of gas pressure, the second piston plate 601 drives the guide rod mechanism 6 to move upward. The guide rod mechanism 6 extends upward through the sleeve assembly 501. The baffle assembly 6012 fixed on the outer circumference of the guide rod mechanism 6 rises synchronously with the guide rod mechanism 6. The diameter of the baffle assembly 6012 is larger than the diameter of the guide rod mechanism 6, which provides support for the support 7. The mounting support 7 in the longitudinal groove at the front end of the guide bracket 2 is sleeved on the outside of the guide rod mechanism 6 and located above the baffle assembly 6012. It rises synchronously with the guide rod mechanism 6. When the mounting support 7 drives the inner fixedly connected mounting plate 7011, guide shaft assembly 7012 and guide wheel assembly 7013 to rise to a height that matches the current rolled steel part 7014, the air pressure sensor 5014 fixed at the front end of the outer periphery of the sleeve assembly 501 detects that the internal air pressure has reached the preset value and transmits the signal to the display assembly 5013. The display assembly 5013 displays the current air pressure status. At this time, by rotating the nut assembly 6013 on the top external thread of the outer periphery of the guide rod mechanism 6, the nut assembly 6013 is tightened downwards, and the mounting support 7 is firmly fixed between the baffle assembly 6012 and the nut assembly 6013, thus completing the height locking. Throughout the height adjustment process, the air pressure sensor 5014 monitors the air pressure changes inside the sleeve assembly 501 in real time and feeds the data back to the display assembly 5013 and the external control system. If abnormal air pressure fluctuations occur, the control system can adjust the output of the push rod 5 in a timely manner to ensure the smooth lifting and lowering of the guide rod mechanism 6 and prevent the guide wheel assembly 7013 from vibrating due to sudden height changes. This height adjustment method, achieved through air pressure transmission, can accurately control the height of the guide wheel assembly 7013, ensuring that it always maintains a suitable contact state with the rolled steel parts 7014 of different specifications. This solves the problem that the existing device has a narrow range of applications and is difficult to adapt to the diverse testing needs of rolled steel parts 7014. At the same time, a stable support environment ensures the consistency of the test data under different working conditions.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
