Description

Technical Field

[0001] This utility model relates to the field of coaxiality detection technology, and more specifically, to a coaxiality detection system. Background Technology

[0002] Coaxiality testing is a crucial step in the machinery and manufacturing industry to ensure the accuracy of component assembly and the stability of system operation. In complex mechanical structures, such as gearboxes and engines, the coaxiality of parts directly affects overall performance and lifespan. Inaccurate coaxiality can lead to vibration, noise, and even damage during equipment operation, thereby increasing maintenance costs and safety hazards. Therefore, accurate coaxiality testing not only effectively controls product quality but also significantly reduces scrap rates in the production process, improving production efficiency and having a major impact on product market competitiveness and corporate economic benefits.

[0003] In existing technologies, non-contact optical vision inspection systems have become the mainstream solution for coaxiality inspection due to their high efficiency, low cost, and ease of operation. However, to comprehensively analyze the coaxiality of the workpiece, it is usually necessary to drive the workpiece to be inspected to rotate in order to obtain images from different angles. The driving methods for workpiece rotation mainly include workpiece self-rotation and friction-driven methods. Workpiece self-rotation, such as fixing the workpiece with a fixture and rotating it, has high requirements for the adaptability and positioning of the fixture, and some irregularly shaped workpieces are difficult to fix effectively. Friction-driven methods drive the workpiece to rotate by frictional contact between the transmission components such as synchronous belts or drive wheels and the workpiece to be measured. It does not require a fixture to drive the workpiece to rotate, thus significantly reducing the accuracy requirements of the fixture. However, in this method, the transmission components are prone to vibration under inertia when contacting or separating from the workpiece, which reduces the stability of power transmission and causes impact on the workpiece to be measured, resulting in workpiece displacement and reducing inspection accuracy. Utility Model Content

[0004] The main objective of this invention is to provide a coaxiality detection system that can solve the problem that existing friction-driven optical vision coaxiality detection systems are prone to vibration and impact on the workpiece under inertia, leading to workpiece displacement and reduced detection accuracy.

[0005] To achieve the above objectives, according to one aspect of the present invention, a coaxiality detection system is provided, including a mounting platform and a drive assembly. The drive assembly is mounted on the mounting platform and can be close to or away from the detection position. The drive assembly includes a synchronous wheel and a buffer part. The synchronous wheel is connected to the buffer part, and the buffer part can apply an elastic buffering force to the synchronous wheel.

[0006] Furthermore, the synchronizing pulley includes a first synchronizing pulley and a second synchronizing pulley, which are spaced apart along the direction of movement.

[0008] Furthermore, a guide rod is provided on the first slider, the guide rod passes through the second slider and can slide relative to the second slider, and the buffer part includes a spring, which is sleeved on the guide rod between the first slider and the second slider.

[0009] Furthermore, a first driving device is provided on the first mounting base, and the synchronous pulley also includes a third synchronous pulley. The third synchronous pulley is located at the driving end of the first driving device, and a synchronous belt is sleeved on the synchronous pulley.

[0010] Furthermore, a second mounting base is provided on the mounting platform, and a first mounting base is mounted on the second mounting base. The second mounting base can move up and down relative to the mounting platform. A second driving device is provided on the second mounting base, which can drive the first mounting base to move closer to or away from the detection position.

[0011] Furthermore, the installation platform is equipped with a lifting component, which can drive the second mounting base to move up and down relative to the installation platform.

[0013] Furthermore, a vision component is also provided on the mounting platform. The vision component includes a camera bracket and a camera. The camera bracket is fixed on the mounting platform, and the camera is mounted on the camera bracket and can move along the camera bracket.

[0014] Furthermore, the camera bracket includes a first guide section extending toward the detection position, allowing the camera to move closer to or further away from the detection position along the first guide section.

[0015] Furthermore, the camera bracket also includes a second guide section, which is disposed on the first guide section and extends vertically.

The buffer part can apply an elastic buffering force to the synchronous pulley. By setting the buffer part, the inertial impact of the synchronous pulley caused by the movement of the drive assembly can be reduced, thereby preventing the workpiece from being deviated due to the inertial impact of the synchronous pulley, improving the stability of power transmission and the accuracy of coaxiality detection.

[0031] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] See also Figures 1 to 11 As shown, this utility model provides a coaxiality detection system, which includes a mounting platform 1 and a drive component 2. The drive component 2 is mounted on the mounting platform 1 and can be close to or away from the detection position. The drive component 2 includes a synchronous wheel 21 and a buffer part 22. The synchronous wheel 21 is connected to the buffer part 22, and the buffer part 22 can apply an elastic buffering force to the synchronous wheel 21.

[0033] In the above technical solution, the mounting platform 1 is used to support other component structures such as the drive assembly 2, ensuring accurate alignment and stable operation of other components. The drive assembly 2 is responsible for rotating the workpiece to be inspected, so that the vision inspection device can capture images of the workpiece from different angles, thereby detecting the coaxiality of the workpiece. The synchronous pulley 21 of the drive assembly 2 is used to tension the synchronous belt and drive the synchronous belt to move, ensuring that the synchronous belt rotates with the workpiece after contacting it. The start and stop of the drive assembly 2 generates inertial force on the synchronous pulley 21, causing the synchronous pulley 21 to vibrate and impact the workpiece, reducing the stability of the workpiece rotation. The buffer part 22 can apply elastic buffering force to the synchronous pulley 21. By setting the buffer part 22, the inertial impact of the synchronous pulley 21 generated by the movement of the drive assembly 2 can be reduced, thereby preventing the workpiece from being deviated by the inertial impact of the synchronous pulley 21, improving the stability of power transmission and the accuracy of coaxiality detection.

[0034] In one embodiment of the present invention, the synchronizing pulley 21 includes a first synchronizing pulley 211 and a second synchronizing pulley 212, the first synchronizing pulley 211 and the second synchronizing pulley 212 are spaced apart along the direction of movement, and the buffer part 22 is disposed between the first synchronizing pulley 211 and the second synchronizing pulley 212 and can apply an elastic buffering force to the first synchronizing pulley 211 and the second synchronizing pulley 212 along the direction of movement.

[0035] In the above technical solution, the first synchronous pulley 211 and the second synchronous pulley 212 are spaced apart along the direction of movement, which can tension the synchronous belt, ensuring that the synchronous belt can fully transmit power to the sample and improve the stability of sample rotation. The buffer part 22 usually includes a spring or an elastic element made of elastic material such as rubber. The buffer part 22 is located between the first synchronous pulley 211 and the second synchronous pulley 212. Its main function is to apply elastic buffering force to the synchronous pulleys between the two synchronous pulleys. When the drive component 2 approaches or moves away from the sample, the instantaneous start and stop action will cause the synchronous pulleys to generate inertia. Under the action of inertia, the first synchronous pulley 211 and the second synchronous pulley 212 will deviate from their original positions and may even collide. By setting the buffer part 22, hard collisions between the first synchronous pulley 211 and the second synchronous pulley 212 can be avoided, protecting the synchronous pulleys from damage. At the same time, it ensures that the first synchronous pulley 211 and the second synchronous pulley 212 can always tension the synchronous belt, ensuring normal power transmission.

[0036] In one embodiment of the present invention, the drive assembly 2 includes a first mounting base 23, a first slide rail 24 is provided on the first mounting base 23, a slider 25 is provided on the first slide rail 24, the slider 25 is slidable along the first slide rail 24, the slider 25 includes a first slider 251 and a second slider 252, a first synchronous wheel 211 is provided on the first slider 251, a second synchronous wheel 212 is provided on the second slider 252, and a buffer part 22 is provided between the first slider 251 and the second slider 252.

[0037] In the above technical solution, the first mounting base 23 serves as the main support structure of the drive assembly, bearing the weight of the entire drive assembly and providing a stable foundation for subsequent component installation and movement. The first slide rail 24 is the guide structure for the movement of the slider 25 in the drive assembly 2. The slider 25 is used to support the synchronous wheel 21. Through the sliding engagement between the first slide rail 24 and the slider 25, the user can manually or automatically adjust the distance between the first synchronous wheel 211 and the second synchronous wheel 212 according to the sample to be tested, in order to adapt to the rotation requirements of samples of different sizes. The buffer part 22 is disposed between the first slider 251 and the second slider 252 to prevent the first slider 251 and the second slider 252 from colliding under inertia, and to reduce the vibration or collision that may occur between the sliders or between the synchronous wheels when the drive assembly 2 rapidly approaches and contacts or separates from the sample.

[0038] In one embodiment of the present invention, a guide rod 26 is provided on the first slider 251, the guide rod 26 passes through the second slider 252 and can slide relative to the second slider 252, and the buffer part 22 includes a spring 221, the spring 221 is sleeved on the guide rod 26 between the first slider 251 and the second slider 252.

[0039] In the above technical solution, the guide rod 26 passes between the first slider 251 and the second slider 252. Its main function is to support the spring 221 and guide the extension and retraction direction of the spring 221, ensuring that the elastic buffering force of the spring 221 can act on the first slider 251 and the second slider 252 along the sliding direction of the slider. The spring 221 is mainly used to provide elastic buffering force between the first slider 251 and the second slider 252. When the first slider 251 and the second slider 252 shift due to inertia, the spring 221 is compressed or stretched. Under the elastic action of the spring 221, the relative position of the first slider 251 and the second slider 252 can remain stable, avoiding the first slider 251 and the second slider 252 from shifting or even colliding due to inertia. This improves the stability and reliability of the power output, reduces the impact of the drive component movement on the workpiece under test, and improves the coaxiality detection accuracy.

[0040] In one embodiment of the present invention, a first driving device 27 is provided on the first mounting base 23, and the synchronous wheel 21 further includes a third synchronous wheel 213. The third synchronous wheel 213 is provided at the driving end of the first driving device 27, and a synchronous belt 29 is sleeved on the synchronous wheel 21. The first driving device 27 can drive the third synchronous wheel 213 to rotate so as to drive the synchronous belt 29 to move around the synchronous wheel 21.

[0041] In the above technical solution, the first driving device 27 typically includes a motor or cylinder, mainly providing power for the rotation of the synchronous pulley 21, thereby driving the sample to rotate via the synchronous belt fitted on the synchronous pulley 21 for coaxiality detection. The third synchronous pulley 213 is located at the driving end of the first driving device 27 and is used to connect the first driving device 27 and the synchronous belt, ensuring that the power output by the first driving device 27 can be converted into the movement of the synchronous belt, improving the efficiency and accuracy of transmission.

[0042] In one embodiment of the present invention, a second mounting seat 3 is provided on the mounting platform 1, and a first mounting seat 23 is provided on the second mounting seat 3. The second mounting seat 3 is capable of lifting and lowering relative to the mounting platform 1. A second driving device 4 is provided on the second mounting seat 3, and the second driving device 4 is capable of driving the first mounting seat 23 to move closer to or away from the detection position.

[0043] In the above technical solution, the second mounting base 3 supports the first mounting base 23. The second mounting base 3 can move up and down relative to the mounting platform 1, thereby driving the first mounting base 23 to move up and down as well. This allows adjustment of the height of the synchronous belt, ensuring that the drive assembly 2 can adapt to samples of different sizes. The synchronous belt can then contact the sample at the most suitable height and drive the sample to rotate, improving the reliability and stability of sample rotation and thus enhancing the accuracy of sample coaxiality detection. The second drive device 4 can drive the first mounting base 23 closer to or further away from the detection position. When the second drive device 4 drives the first mounting base 23 closer to the detection position, the synchronous belt contacts the workpiece to be tested, causing the workpiece to rotate for coaxiality detection. When the detection is complete and rotation needs to be stopped, the second drive device 4 drives the first mounting base 23 to move away from the detection position, disengaging the drive assembly 2 from the workpiece to be tested.

[0044] In one embodiment of this utility model, a lifting component 5 is provided on the mounting platform 1, and the lifting component 5 can drive the second mounting base 3 to move up and down relative to the mounting platform 1.

[0045] In the above technical solution, the lifting component 5 typically includes an electric lifting platform, a hydraulic lifting system, or a pneumatic lifting device. The lifting component 5 enables the second mounting base 3 to be raised or lowered in the vertical direction relative to the mounting platform 1, thereby adjusting the relative height between the drive component 2 on the second mounting base 3 and the sample to be tested. This ensures that the drive component 2 can adapt to samples of different sizes, allowing the synchronous belt to contact the sample from the most suitable height and drive the sample to rotate, thus improving the reliability and stability of the sample rotation and thereby improving the accuracy of the sample coaxiality detection.

[0046] The lifting assembly 5 can be controlled manually or automatically. The automated control of the lifting assembly 5 can be seamlessly integrated with the drive process and sample change process. During the test preparation stage, the lifting assembly 5 can precisely move the drive assembly to the set height to ensure accurate and stable sample drive. After the test is completed, the lifting assembly can automatically move the drive assembly 2 back to its original position or a safe position to prepare for the next test.

[0047] In one embodiment of this utility model, the lifting components 5, such as electric lifting platforms, hydraulic lifting systems, or pneumatic lifting devices, are installed in the cabinet space below the installation platform 1. This effectively utilizes the space below the installation platform 1 and avoids the lifting components 5 occupying the space of the drive components and clamping components, thus preventing them from affecting the normal detection of coaxiality. This achieves a compact layout and space optimization for the coaxiality detection system. Hydraulic or pneumatic lifting devices generate noise and vibration during operation. Placing them in the cabinet space below the installation platform 1, away from the detection position, provides a certain degree of sound insulation and vibration reduction, helping to improve detection accuracy and reduce the impact of external factors on the detection results.

[0048] In one embodiment of the present invention, a clamping component 6 is provided on the installation platform 1. The clamping position of the clamping component 6 corresponds to the detection position. The clamping component 6 includes a first clamping part 61 and a second clamping part 62. The second clamping part 62 can move closer to or further away from the first clamping part 61 to adjust the clamping space between the first clamping part 61 and the second clamping part 62.

[0049] In the above technical solution, the clamping position of the clamping component 6 corresponds to the detection position, enabling the sample to be fixed in the optimal detection position during the detection process through the cooperation of the first clamping part 61 and the second clamping part 62. The clamping action of the first and second clamping parts ensures that the sample will not shift or shake during the detection process, which is crucial for high-precision detection such as coaxiality. The second clamping part 62 can move relative to the first clamping part 61 to adjust the clamping space between them. This design allows the clamping component to flexibly adapt to samples of different sizes and shapes, improving the flexibility and adaptability of the coaxiality detection system. The clamping component can be integrated with automated control. The movement of the second clamping part 62 can be driven by a motor or cylinder to achieve automatic clamping and release before and after detection, eliminating the need for manual operation. Automated clamping and release not only improves detection efficiency and reduces manual intervention but also ensures that the sample is fixed in a consistent state during each detection, thereby improving the repeatability and reliability of the detection results.

[0050] In one embodiment of the present invention, a vision component 7 is further provided on the mounting platform 1. The vision component 7 includes a camera bracket 71 and a camera 72. The camera bracket 71 is fixed on the mounting platform 1, and the camera 72 is mounted on the camera bracket 71 and can move along the camera bracket 71.

[0051] In the above technical solution, the vision component 7 is used to acquire images of the workpiece under test at multiple angles during rotation, providing image data for subsequent image processing to obtain the coaxiality of the workpiece. The vision component 7 includes a camera bracket 71 and a camera 72, where the camera bracket 71 is fixed on the mounting platform 1, providing a stable mounting base for the camera 72. The camera 72 is mainly used to capture images and send them to the data processing center for processing. The camera 72 is mounted on the camera bracket 71 and can move along it, meaning that the camera's position and angle can be adjusted to ensure that the camera is aligned with the area of ​​the sample to be tested, thereby obtaining optimal image quality and detection accuracy. The vision component 7 can be combined with automated control and linked with other components in the detection process, such as lifting components and clamping components, to achieve a fully automated detection process from sample loading, alignment, imaging to unloading. Simultaneously, it automatically adjusts the shooting height and focal length according to the sample position, significantly improving detection efficiency and accuracy.

[0052] In one embodiment of the present invention, the camera bracket 71 includes a first guide segment 711 extending toward the detection position, and the camera 72 can move closer to or away from the detection position along the first guide segment 711.

[0053] In the above technical solution, the first guide segment 711 provides a precise movement path for the camera 72, ensuring that the camera can accurately align with the key measurement area of ​​the sample during the detection process. By adjusting the camera position along the guide segment, finer focus adjustment can be achieved, thereby acquiring higher resolution and more detailed image information.

[0054] In one embodiment of the present invention, the camera bracket 71 further includes a second guide section 712, which is disposed on the first guide section 711 and extends in a vertical direction. The second guide section 712 can move closer to or further away from the detection position along the first guide section 711. The camera 72 is disposed on the second guide section 712 and can move up and down along the second guide section 712.

[0055] In the above technical solution, the second guide section 712 provides support and guidance for the height adjustment of the camera 72. Through the combined use of the first guide section 711 and the second guide section 712, the system can achieve position adjustment of the camera in both horizontal and vertical dimensions, providing the camera with precise positioning capabilities in three-dimensional space. The camera can not only move closer to or further away from the sample along the first guide section, but also move up and down along the second guide section, ensuring that optimal images can be obtained under various sample heights and sizes, thus improving the accuracy of coaxiality detection.

[0056] In one embodiment of this utility model, a baffle 28 is also provided on the second mounting base 3. The baffle 28 is located outside the first mounting base 23. The baffle 28 can prevent debris from falling into the drive assembly 2, protect the normal operation of the drive assembly 2, and thus improve the safety and reliability of the coaxiality detection system.

[0057] In one embodiment of the present invention, a second slide rail 31 is further provided on the second mounting base 3, and a slide groove corresponding to the second slide rail 31 is provided at the bottom of the first mounting base 23. The first mounting base 23 can slide along the second slide rail 31 to move away from or closer to the detection position.

[0058] In the above technical solution, the second slide rail 31 is used to guide the sliding of the first mounting base 23, so that the first mounting base 23 can slide smoothly and accurately away from or near the detection position, which improves the sliding stability of the first mounting base 23, minimizes the vibration and impact when the synchronous belt on the first mounting base 23 comes into contact with the workpiece to be detected, and helps to improve the detection accuracy of the coaxiality detection system.

[0059] In one embodiment of the present invention, the coaxiality detection system further includes a backlight source, which is disposed on the mounting platform 1 on the side of the detection position away from the vision component 7.

[0060] In the above technical solution, the backlight source is used to increase the contrast between the sample outline and the background, which is especially effective in dark room environments. This allows the camera to capture clearer and more distinct edges and details. By enhancing the contrast and clarity of the image, the image recognition and analysis capabilities of the detection system are strengthened. Even subtle differences in coaxiality can be accurately identified, thereby improving detection accuracy and reliability.

[0061] In one embodiment of this invention, the sample to be tested is placed on a sample fixing device and can rotate relative to the sample fixing device. The sample fixing device includes a fixing rod or a fixing seat. When testing the sample, the sample fixing device is placed into the clamping assembly 6, and the fixing device is clamped by manually or automatically controlling the first clamping part 61 or the second clamping part 62, thereby realizing the installation and fixing of the sample to be tested. Then the system is started, and the second driving device 4 drives the first mounting seat 23 to move towards the sample to be tested, so that the synchronous belt contacts the sample surface. At the same time, the first driving device 27 drives the synchronous belt 29 to rotate, thereby driving the sample to rotate. Then the vision assembly 7 adjusts the horizontal and vertical position of the camera to ensure that the camera 72 can accurately align with the sample to be tested and capture a clear image. When the sample rotates to a specified angle, or after a preset time interval, the system controls the camera 72 to automatically capture the image and transmit it to the image processing system. The image processing system extracts the geometric features of the sample through image processing technology, calculates the coaxiality and compares it with preset qualified parameters. If it is qualified, a green light indicates that it is qualified; if it is unqualified, an alarm system is triggered. Then the synchronous belt returns to its position, and the sample to be tested stops rotating, completing one test.

[0062] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The mounting platform 1 is used to support the drive assembly 2 and other component structures, ensuring the accurate alignment and stable operation of other components. The drive assembly 2 is responsible for driving the workpiece to be inspected to rotate, so that the vision inspection device can capture workpiece images from different angles, thereby detecting the coaxiality of the workpiece to be inspected. The synchronous pulley 21 of the drive assembly 2 is used to tension the synchronous belt and drive the synchronous belt to move, ensuring that after the synchronous belt contacts the workpiece to be inspected, it drives the workpiece to rotate with the movement of the synchronous belt. The start and stop of the drive assembly 2 generates an inertial effect on the synchronous pulley 21, causing the synchronous pulley 21 to vibrate and impact the workpiece, reducing the stability of the workpiece rotation. The buffer part 22 can apply an elastic buffering force to the synchronous pulley 21. By setting the buffer part 22, the inertial impact of the synchronous pulley 21 generated by the movement of the drive assembly 2 can be reduced, thereby preventing the workpiece from being deviated by the inertial impact of the synchronous pulley 21, improving the stability of power transmission and the accuracy of coaxiality detection.
