Description

Technical Field

[0001] The invention belongs to the field of testing platforms, and in particular relates to an offline testing platform for harmonic reducers. Background Art

[0002] As a high-precision, high-ratio transmission device, harmonic reducers are widely used in industrial automation, robotics and precision machinery. As the manufacturing industry continues to increase its requirements for product quality, the performance testing of harmonic reducers has become increasingly important. However, existing harmonic reducer testing technologies and equipment have many problems and limitations, making it difficult to meet the needs of modern industrial production for efficient, accurate and comprehensive testing.

[0003] Traditional detection methods often rely on manual operation, which is not only inefficient but also easily affected by human factors, resulting in insufficient consistency and reliability of the detection results. Existing detection equipment can usually only detect a single or a few parameters of the harmonic reducer, such as transmission accuracy or backlash, making it difficult to fully evaluate the overall performance of the reducer. This one-sided detection method may miss key performance indicators and affect the quality of the final product. The accuracy of many detection equipment is insufficient to meet the detection needs of high-precision harmonic reducers, especially in the measurement of small errors. Existing detection equipment often lacks automation and intelligent functions, requiring a lot of manual intervention and adjustment, which not only increases labor intensity but also prolongs the detection time. Many detection equipment have poor adaptability and are difficult to cope with harmonic reducers of different models and specifications, limiting their wide application on production lines.

[0004] Another significant problem is that existing equipment has limited capabilities in data collection and analysis, making it difficult to achieve real-time monitoring and trend analysis, and unable to provide effective data support for the continuous improvement of the production process. In addition, the operation of many testing equipment is complicated and requires professional technicians to operate, which increases the training costs and human resource pressure of enterprises. In terms of reliability, some testing equipment lacks stability and is easily affected by environmental factors, resulting in fluctuations and inconsistencies in test results. Safety is also an issue worthy of attention. Some testing processes may have safety hazards, increasing the occupational risks of operators.

[0005] Existing testing equipment is often difficult to effectively integrate with the company's production management system and quality control system, affecting the overall production efficiency and quality management level. These problems combined not only affect the quality control effect of the harmonic reducer, but also increase production costs and reduce the competitiveness of the company. Therefore, the development of a new, efficient, and intelligent harmonic reducer offline testing station has become an urgent need in the industry. The new testing station needs to be able to improve detection accuracy and efficiency, achieve comprehensive performance evaluation, have automation and intelligent functions, adapt to different types of harmonic reducers, provide powerful data analysis capabilities, be easy to operate, highly reliable, and be able to seamlessly integrate with other systems of the company to comprehensively improve the quality control level of the harmonic reducer and meet the high standards of modern industrial production.

[0009] The test bench uses multiple screw moving devices (first, second and third screw moving devices), which significantly improves the accuracy and controllability of the test process. Through the precise control of the screw drive motor, small adjustments and precise positioning of the test components can be achieved, which is crucial for the detection of precision components such as harmonic reducers. The design of the load detection module is also a highlight. It includes a series of precision components from load fixtures to load motors, such as load air claws, bearing seats, torque sensors and couplings. This modular design is not only easy to assemble and maintain, but also enables high-precision load detection. In particular, the introduction of the torque sensor enables the test bench to accurately measure the performance of the harmonic reducer under different load conditions. The setting of the load clamping cylinder further enhances the stability and reliability of the detection process.

[0010] The design of the spare module is another innovation, which adds additional functionality and flexibility to the test bench. The provision of spare tooling and spare clamping cylinders enables the test bench to quickly switch between different types of test tasks or adapt to different types of harmonic reducers, greatly improving the versatility and production efficiency of the equipment. The center lines of the load detection drive module and the spare drive module arranged in the cavity below the test bench body are coaxial with the center lines of the load detection module and the spare module, respectively.

[0017] As a preferred embodiment, cooling fans are symmetrically arranged on the left and right sides of the upper end surface of the cantilever box, and the heat in the cantilever box is discharged through the cooling fans.

[0018] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: the L-shaped test bench body improves the overall stability, reduces the vibration and error during the detection process, and thus improves the detection accuracy. The application of multiple screw moving devices realizes the precise positioning and fine-tuning of the detection components, which not only improves the accuracy of the detection, but also increases the repeatability of the detection process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 4As shown, a harmonic reducer offline detection bench comprises a test bench body 1 with an L-shaped structure, a first screw moving device 2 is arranged on the upper part of the front end surface of the test bench body 1, a first screw driving motor 21 is installed on the upper end of the first screw moving device 2, a second screw moving device 3 is arranged at the rear of the first screw moving device 2, a third screw moving device 4 is arranged at the lower front side of the inner cavity of the test bench body 1, a load detection module 5 is arranged in front of the first screw moving device 2, and the load detection module 5 is sequentially provided with a load tooling 51, a load air claw 52, ​​a first load bearing seat 53, a torque sensor 54, a second load bearing seat 55, a coupling 56 and a load motor 57 from bottom to top, and the third screw moving device 4 is arranged at the lower front side of the inner cavity of the test bench body 1, and a load detection module 5 is arranged in front of the first screw moving device 2. A load bearing seat 53 is provided with load clamping cylinders 58 on the left and right sides, a spare module 6 is provided on one side of the load detection module 5, a spare tooling 61 is installed at the lower part of the spare module 6, and spare clamping cylinders 62 are provided on the left and right sides of the upper end surface of the spare tooling 61. A cavity is provided below the test bench body 1, and a load detection drive module 7 and a spare drive module 8 are provided in the cavity. The center line of the load detection drive module 7 is coaxial with the center line of the load detection module 5, and the center line of the spare drive module 8 is coaxial with the center line of the spare module 6. A connecting frame 9 is installed below the end surface of one side of the test bench body 1, one end of the connecting frame 9 is connected to the test bench body 1, and a cantilever box 10 is installed on the other end.

[0028] The working principle of this harmonic reducer offline test bench is mainly based on precision control and multifunctional integration. The working process is as follows: the harmonic reducer to be tested is placed on the load fixture 51. The first screw moving device 2 accurately adjusts the position of the load detection module 5 through the control of the first screw drive motor 21 to ensure the correct docking with the harmonic reducer. The load claw 52 and the load clamping cylinder 57 work together to firmly fix the harmonic reducer. The first load bearing seat 53 and the second load bearing seat 55 provide stable support to ensure axial stability during the test. The torque sensor 54 is used to accurately measure the torque output of the harmonic reducer under different load conditions. The coupling 56 connects the torque sensor and the load motor 57, and the load motor 57 provides a controllable load torque. The second screw moving device 3 and the third screw moving device 4 may be used to adjust other test parameters or the position of auxiliary components. During the test, the load detection drive module 7 transmits power through the cavity to drive the harmonic reducer to operate. The spare module 6 and the spare drive module 8 provide flexible replacement options for different models of harmonic reducers or other test requirements. The connecting frame 9 and the cantilever box 10 may be used to install a control system, a display or other auxiliary equipment to facilitate operators to monitor and control the entire test process.

[0029] The load detection drive module 7 is coaxially provided with a precision air claw 71, a drive bearing seat 72, a drive locking device 73, a detection coupling 74, and a drive motor 75 from top to bottom. The drive bearing seat 72 is arranged on the front end side of the third screw moving device 4, and the third screw moving motor 41 is installed on the lower end face of the third screw moving device 4.

[0030] The module adopts a coaxial design, and precisely arranges key components such as precision air grippers, drive bearing seats, drive locking devices, detection couplings and drive motors along the same center line. This compact structural design greatly improves the accuracy and stability of detection. In traditional equipment, these components are often arranged in a scattered manner, resulting in large concentricity errors, which affects the accuracy of detection.

[0031] The introduction of precision air grippers is an important innovation. The air grippers can provide precise and controllable clamping force to ensure reliable connection between the test piece and the drive system, avoiding the slipping problem existing in traditional mechanical fixtures. This design improves the repeatability and consistency of the detection process. The setting of the drive locking device is another key point. By locking the drive system, external vibrations and disturbances can be effectively isolated, providing an ideal environment for accurate detection. Traditional equipment lacks this isolation mechanism and is easily disturbed and causes measurement errors.

[0032] The use of the detection coupling is also an innovation. This flexible coupling can absorb slight deviations of the axis, avoiding the stress concentration problem in the rigid connection, thereby improving the reliability of the detection. The drive bearing seat is set on the front side of the third screw moving device and driven by the third screw moving motor, realizing the precise displacement control of the drive system in the vertical direction. This design not only optimizes the spatial layout, but also provides more flexibility and adjustability for the detection process.

[0033] The role of this setting is multifaceted: it significantly improves the accuracy and repeatability of detection. Innovative designs such as coaxial design, precision air grippers, drive locking devices and flexible couplings effectively eliminate various interference factors and ensure the reliability and consistency of detection data. It enhances the automation and intelligence level of the detection process. The introduction of the third screw moving device enables the detection process to achieve automatic displacement control, improving efficiency and convenience. It improves the adaptability of the detection equipment. By adjusting the displacement of the drive system, it can adapt to test pieces of different sizes and specifications, improving the versatility of the equipment. This design optimizes space utilization efficiency, improves the integration of the equipment, and is conducive to the realization of a more compact and efficient detection system. Modular design improves the maintainability and scalability of the equipment. The independent arrangement of each component facilitates individual replacement and upgrading, extending the service life of the equipment. This innovative design lays the foundation for subsequent intelligent upgrades, such as the easy integration of advanced sensors and control systems to achieve more advanced detection functions.

[0034] The backup drive module 8 is coaxially provided with a hydraulic expansion sleeve 81, a backup torque sensor 82, a backup bearing seat 83, a backup coupling 84 and a backup drive motor 85 from top to bottom. The backup bearing seat 83 is arranged on one side of the front end of the third screw moving device 4.

[0035] The module adopts a coaxial structure design similar to the load detection drive module. This unified modular design greatly improves the consistency and compatibility of the system. Compared with the traditional scattered layout, this compact coaxial layout not only saves space, but also ensures precise alignment and stability during the detection process.

[0036] The introduction of the hydraulic expansion sleeve design is a key innovation. Unlike ordinary mechanical fixtures, hydraulic expansion sleeves can provide uniform circumferential pressure to ensure reliable connection between the test piece and the drive system, avoiding stress concentration and slippage problems in traditional fixtures. This design greatly improves the accuracy and repeatability of detection. The setting of the spare torque sensor allows the module to perform not only conventional load detection but also torque detection. This multifunctional integrated design greatly improves detection efficiency and reduces the time and process of replacing modules, which is not available in traditional single-function equipment.

[0037] The design of the spare bearing seat and spare coupling is consistent with that of the load detection drive module. This unified design simplifies the maintenance and replacement process and improves the compatibility and maintainability of the system. The spare bearing seat is set on the front side of the third screw moving device, which is the same as the layout of the load detection drive module. This consistent layout design allows the two modules to share the third screw moving device, realizing efficient reuse of resources.

[0038] The role of this setting is multifaceted: significantly improve the detection capability and efficiency. Through the spare drive module, the system can not only perform standard load detection, but also torque detection, thus realizing multifunctional integrated detection, greatly saving detection time and manpower. Enhance the flexibility and adaptability of the system. When the load detection module fails or requires maintenance, it can quickly switch to the spare module to ensure the continuity of the detection work and improve the availability of the equipment. The unified modular design and consistent layout arrangement improve the maintainability and scalability of the system. The independence of each module makes the replacement and upgrade of a single module simple and efficient, extending the service life of the entire system. The use of hydraulic expansion sleeves improves the reliability and repeatability of detection and ensures high-quality detection data. The design of the shared third screw moving device optimizes the space utilization efficiency, improves the integration of the system, and is conducive to the realization of more compact detection equipment. This modular and multifunctional integrated design lays the foundation for subsequent intelligent upgrades, such as the easy integration of advanced sensors, control systems and automation functions to achieve more advanced detection and management capabilities.

[0039] The middle part of the lower end surface of the cantilever box 10 is connected to the connecting frame 9, and a display 11 is installed above the front end surface of the cantilever box 10, and a control button 12 is arranged below the display 11. The control button 12 controls the actions of the first screw moving device 2, the second screw moving device 3, the third screw moving device 4, the load detection module 5, the spare module 6, the load detection drive module 7 and the spare drive module 8 in the test bench body 1.

[0040] Traditional testing equipment usually arranges the control system and display in a dispersed manner or uses a separate console, while this design integrates the display and control buttons on the cantilever box and connects them to the test bench body through a connecting frame. This integrated design has the following significant advantages: it optimizes the use of the operating space, concentrates the control interface in a compact area, enables the operator to complete all operations in a fixed position, and improves work efficiency. The display is located above the cantilever box and the control buttons are located below. This layout conforms to the principles of ergonomics, reduces operator fatigue, and improves comfort for long-term work. The control of multiple complex modules (such as the first, second, and third screw moving devices, load detection modules, spare modules, etc.) is achieved through a single control interface, which simplifies the operation process and reduces the difficulty and error rate of operation. In addition, this design enhances the integrity and coordination of the system. All control instructions are issued through a central system, which is conducive to more accurate synchronous control and data acquisition. From the perspective of maintenance and upgrade, the centralized control system is also easier to update software and maintain hardware. The design of the cantilever box also provides flexibility. The operator can adjust the angle and position of the display as needed to adapt to different working environments and personal preferences. This integrated design improves the aesthetics and professionalism of the entire testing bench and helps to enhance the market competitiveness of the product.

[0041] The four corners of the lower end surface of the test bench body 1 are provided with footrests 13 , and the lower end surface of the footrest 13 is provided with a fixed suction cup 14 , and the fixed suction cup 14 includes a rubber buffer pad 141 and a suction cup 142 , the rubber buffer pad 141 is connected to the footrest 13 , and the suction cup 142 is arranged below the rubber buffer pad 141 .

[0042] Traditional testing equipment usually uses a simple fixed foot or bolt fixing method, while this design uses a combination of footrests, fixed suction cups, rubber cushions and suction cups. This innovative design brings many advantages: First, the footrests are set at the four corners of the test bench body, providing more uniform and stable support, effectively reducing the vibration and shaking of the equipment during operation.

[0043] The design of fixed suction cups greatly enhances the stability and safety of the equipment. The suction cups can be firmly attached to the ground to prevent the equipment from shifting or tilting during operation, which is particularly suitable for high-precision detection equipment that requires precise positioning. The introduction of rubber buffer pads is another innovation, which plays a role of buffering and shock absorption between the footrest and the suction cups. This can not only further reduce the vibration of the equipment during operation, but also absorb the vibration from the external environment and improve the detection accuracy. The rubber buffer pads can also compensate for minor unevenness of the ground to ensure that the equipment remains level. The suction cups are set below the rubber buffer pads. This design not only ensures the adsorption force, but also provides a certain degree of flexibility through the buffer structure above, making the entire support system both stable and adaptable.

[0044] A second screw drive motor 31 is arranged above the second screw moving device 3, which drives the second load bearing seat 55, the coupling 56 and the load motor 57 in the load detection module 5 to move through the first screw moving device 2, and drives the first load bearing seat 53 and the torque sensor 54 in the load detection module 5 to move through the second screw moving device 3.

[0045] The design adopts a dual screw moving device configuration, namely the first screw moving device and the second screw moving device. This dual control mechanism greatly improves the accuracy and flexibility of the system. Unlike the traditional single moving mechanism, this design allows different parts of the load detection module to move independently, achieving more precise position adjustment and control. The movement of the second load bearing seat, coupling and load motor is controlled by the first screw moving device, while the movement of the first load bearing seat and torque sensor is controlled by the second screw moving device. This separate control is an important innovation.

[0046] This design allows the system to accurately position and adjust different parts of the harmonic reducer under test independently, greatly improving the flexibility and accuracy of the test. An independent second screw drive motor is set above the second screw moving device. This configuration ensures that the two moving devices can operate independently, improving the response speed and control accuracy of the system.

[0047] The effects of this setup are multifaceted: It significantly improves the accuracy and controllability of detection. By independently controlling different parts of the load detection module, the relative positions of the various components can be precisely adjusted to accommodate harmonic reducers of different specifications and models, improving the adaptability and accuracy of detection. It enhances the flexibility and versatility of the system. This design allows the system to perform more complex detection operations, such as measuring parameters at different positions at the same time, or performing dynamic adjustments and tests, which are difficult to achieve in traditional single-movement mechanism equipment.

[0048] The design of the double-screw moving device improves the stability and reliability of the system. By distributing the load and precise control, the risk of single-point failure is reduced and the reliability of the overall system is improved. This design optimizes the efficiency of space utilization. Although two moving devices are used, the compactness of the system is still maintained through careful layout. Independent mobile control lays the foundation for subsequent automation and intelligent upgrades. Advanced control algorithms and sensor systems can be easily integrated to achieve more advanced automatic adjustment and intelligent detection functions. This design improves the maintainability and scalability of the system. Each moving device can be independently maintained and upgraded, which prolongs the service life of the entire system and also facilitates possible functional expansion in the future.

[0049] The cooling fans 15 are symmetrically arranged on the left and right sides of the upper end surface of the cantilever box 10 , and the heat in the cantilever box 10 is discharged through the cooling fans 15 .

[0050] The design sets cooling fans symmetrically on the left and right sides of the upper end of the cantilever box. This symmetrical layout is an important innovation. Traditional testing equipment usually uses a single fan or natural heat dissipation, which makes it difficult to effectively handle the heat generated during the operation of the equipment. This symmetrical dual-fan design not only improves the heat dissipation efficiency, but also ensures the uniformity of the temperature distribution inside the box. The cooling fan is set on the upper end of the cantilever box, which utilizes the natural convection effect of rising hot air. This design fully considers the principles of thermodynamics and is more efficient than traditional side or bottom heat dissipation. The heat in the cantilever box is discharged through active heat dissipation. This active heat dissipation strategy is more effective than passive heat dissipation and can better control the internal temperature of the equipment.

[0051] The role of this setting is multifaceted: it significantly improves the heat dissipation efficiency of the equipment, effectively reduces the operating temperature of internal components, and prolongs the service life of electronic components and mechanical parts. Temperature control is particularly important for precision testing equipment, as temperature fluctuations may lead to measurement errors and component performance degradation. The symmetrical dual-fan design ensures the uniformity of temperature distribution inside the box, avoids local overheating, and improves the stability and reliability of the entire system. This is essential for maintaining detection accuracy, as uneven temperature distribution may cause mechanical deformation and performance deviation of electronic components. The active heat dissipation design improves the adaptability of the system, allowing the equipment to maintain stable operation under different environmental conditions. This design is particularly suitable for scenarios with long-term continuous operation, and can effectively prevent performance degradation caused by heat accumulation. The heat dissipation design on the upper end optimizes space utilization, does not occupy the side or bottom space, and is conducive to the compact layout of the equipment. This heat dissipation design provides the possibility for subsequent intelligent upgrades, such as integrating temperature sensors and intelligent control systems to achieve adaptive heat dissipation control.
