The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

A first torque sensor 3 is installed on the side of the servo motor 2 near the reducer 10. The two ends of the first torque sensor 3 are fixedly connected to the output end of the first servo motor 2 and the input end of the reducer 10, respectively. A fixed frame 11 is fixedly connected to the top of the base 1. A first laser ranging sensor 12 is installed on both sides and the top and bottom of the fixed frame 11.

[0020] In the specific implementation process, it is worth noting that, through the cooperation between the base 1, the first servo motor 2, the first torque sensor 3, and the reducer 10, the first servo motor 2 provides the power source for the performance testing of the reducer 10. The output end of the first servo motor 2 is connected to one end of the first torque sensor 3, and the other end of the first torque sensor 3 is connected to the input end of the reducer 10. During the testing process of the reducer 10, the first torque sensor 3 measures the torque value at the input end of the reducer 10 in real time and transmits the data to the controller 13 for subsequent torque data calculation. Through the cooperation between the base 1, the first servo motor 2, the first torque sensor 3, the fixing frame 11, and the first laser ranging sensor 12, multiple first lasers... The ranging sensors 12 are mounted on the top of the base 1 via the fixing bracket 11, and are distributed symmetrically on both sides and top and bottom around the mounting axis of the first torque sensor 3. The distance and angle between the output axis of each first laser ranging sensor 12 and the first torque sensor 3 are consistent. Through the cooperation between the base 1, the electric lifting platform 4, the lifting seat 5, and the controller 13, the electric lifting platform 4 supports the lifting seat 5. By controlling the electric lifting platform 4, the height of the lifting seat 5 can be adjusted and stable support maintained. Through the cooperation between the lifting seat 5, the first slide rail 6, the first moving seat 7, the first threaded screw 8, and the second servo motor 9, by controlling the second servo motor 9, the first threaded screw 8 is driven to rotate, causing the first moving seat 7 to rotate. The movable seat 7 moves horizontally and adjusts its position stably on top of the lifting seat 5. Through the cooperation between the first movable seat 7 and the reducer 10, the top of the first movable seat 7 has multiple T-slots. The reducer 10 can be fixed to the top of the first movable seat 7 with bolts and T-shaped clips, thus securing the reducer 10 and enabling installation and testing of reducers 10 of different specifications and sizes.

The first laser rangefinder 12 measures the distance between itself and the input end of the reducer 10 and transmits the measurement data to the controller 13 in real time. The controller 13 automatically controls the electric lifting platform 4 and the second servo motor 9 according to the data difference of each first laser rangefinder 12 to correct the height and position of the reducer 10, so that the input end shaft of the reducer 10 is precisely aligned with the mounting shaft of the first torque sensor 3. Through the cooperation between the base 1, the first servo motor 2, the first torque sensor 3, the electric lifting platform 4, the lifting seat 5, the first slide rail 6, the first moving seat 7, the first threaded screw 8, the second servo motor 9, and the reducer 10,After the reducer 10 is adjusted to the specified height and position, the input shaft of the reducer 10 coincides with the mounting shaft of the first torque sensor 3. A rigid coupling is used to connect the input end of the reducer 10 and the mounting shaft of the first torque sensor 3 to ensure the accuracy and stability of power transmission and avoid additional stress that could affect the accuracy of the detection data. The first servo motor 2 serves as the detection power source. The controller 13 controls the first servo motor 2 to apply loads of different speeds and torques to the input end of the reducer 10 to simulate the power transmission process in the actual working scenario. The torque value at the input end of the reducer 10 is accurately measured by the first torque sensor 3, and the measurement data is transmitted to the controller 13 in real time so that the controller 13 can perform subsequent torque data calculations. The system consists of a base 1, a first servo motor 2, a first torque sensor 3, an electric lifting platform 4, a lifting seat 5, a first slide rail 6, a first moving seat 7, a first threaded screw 8, a second servo motor 9, a reducer 10, a fixed frame 11, and a first laser rangefinder 1. The coordination between the first laser rangefinder 10 (2) and the controller (13) involves real-time monitoring of the position of the input end of the reducer 10 by the first laser rangefinder 12, transmitting the position data to the controller (13) in real time. Based on the position data, the controller (13) automatically controls the electric lifting platform (4) and the second servo motor (9) to automatically adjust the height and position of the reducer 10. This ensures precise automatic alignment of the input shaft of the reducer 10 with the mounting shaft of the first torque sensor (3), facilitating accurate installation of the reducer 10 and the first torque sensor (3). This avoids additional stress caused by human operation, which could affect the accuracy of the detection data. It also reduces the time required for position correction during installation of reducers 10 of different models and sizes, ensuring the accuracy and stability of power transmission and improving detection accuracy and efficiency. The specific models of the first servo motor (2), first torque sensor (3), electric lifting platform (4), second servo motor (9), first laser rangefinder 12, and controller (13) are not limited, as long as they meet the usage requirements.
[0021] Furthermore, a second slide rail 14 is fixedly connected at equal intervals to the top of the base 1 on the side away from the first servo motor 2. A second movable seat 15 is slidably connected to the outer wall of the second slide rail 14. A second threaded screw 16 is rotatably connected to the base 1 below the second movable seat 15. The second threaded screw 16 is meshed with the second movable seat 15. A third servo motor 17 is installed on one end of the base 1 at the second threaded screw 16. The output end of the third servo motor 17 is connected to the second threaded screw 16 for transmission. A fixed bracket 11 is fixedly connected to the top of the second movable seat 15 on the side near the reducer 10. The second laser rangefinder 18 is installed on both sides and the top and bottom of the fixed frame 11 of the 15. The second laser rangefinder 18 is connected to the output end of the reducer 10. A magnetic powder brake 20 is installed on the top side of the second moving seat 15 away from the reducer 10. A second torque sensor 19 is installed on the top of the second moving seat 15. The two ends of the second torque sensor 19 are fixedly connected to the output end of the reducer 10 and the input end of the magnetic powder brake 20, respectively. The third servo motor 17, the second laser rangefinder 18, the second torque sensor 19 and the magnetic powder brake 20 are all electrically connected to the controller 13.
[0022] In the specific implementation process, it is worth noting that through the cooperation between the base 1, the second slide rail 14, the second movable seat 15, the second threaded screw 16, and the third servo motor 17, the second movable seat 15 is stably supported on the top of the base 1. By controlling the third servo motor 17, the second threaded screw 16 is driven to rotate, enabling the second movable seat 15 to perform stable horizontal movement and position adjustment. Through the cooperation between the fixing frame 11, the second movable seat 15, the second laser rangefinder 18, and the second torque sensor 19, multiple second laser rangefinders 18 are mounted on the top of the second movable seat 15 via the fixing frame 11, and are distributed symmetrically on both sides and top and bottom around the mounting axis of the second torque sensor 19. The distance and angle between the mounting shafts of the two laser rangefinders 18 and the second torque sensor 19 are kept consistent. Through the cooperation of the reducer 10, the fixing bracket 11, the controller 13, the second moving seat 15, the second threaded screw 16, the third servo motor 17, and the second laser rangefinders 18, when the second moving seat 15 moves, each second laser rangefinder 18 measures the distance between itself and the output end of the reducer 10 and transmits the data to the controller 13. When the measured values of each second laser rangefinder 18 are consistent, the second moving seat 15 moves to the designated position, and the controller 13 automatically stops the third servo motor 17, realizing the movement and precise correction of the position of the second moving seat 15. The coordination between the movable seat 15, the second torque sensor 19, and the magnetic powder brake 20 is as follows: After the second movable seat 15 moves to the designated position, the output shaft of the reducer 10 coincides with the mounting shaft of the second torque sensor 19. A rigid coupling is used to connect the output end of the reducer 10 and the mounting shaft of the second torque sensor 19 to ensure the accuracy and stability of power transmission and avoid additional stress that could affect the accuracy of the detection data. The magnetic powder brake 20 is connected to the end of the second torque sensor 19 furthest from the reducer 10, serving as a load device. The controller 13 controls the magnetic powder brake 20 to apply different torque loads to the output end of the reducer 10, simulating the load conditions under actual working conditions, and transmitting the load through the second torque sensor 19. The torque value at the output end of the reducer 10 is accurately measured, and the measurement data is transmitted to the controller 13 in real time. The controller 13 then compares the actual torque values at the input and output ends of the reducer 10 with the design values to comprehensively test the performance of the reducer 10. This is achieved through the cooperation of the base 1, reducer 10, second slide rail 14, second moving seat 15, second threaded screw 16, third servo motor 17, second laser rangefinder 18, second torque sensor 19, and magnetic powder brake 20. The second torque sensor 19 and magnetic powder brake 20 are designed to be movable. By moving the second moving seat 15, multiple second laser rangefinders 18 sense the distance between it and the output end of the reducer 10. When the measured values are consistent...Stop moving the second moving seat 15 so that the output shaft of the reducer 10 coincides with the mounting shaft of the second torque sensor 19. This ensures precise connection between the second torque sensor 19 and the magnetic powder brake 20 and the output of the reducer 10, avoiding errors caused by human operation and preventing additional stress at the output of the reducer 10. This ensures the accuracy and stability of power transmission, further improving the precision of detection data and the installation efficiency of the detection equipment. The specific models of the third servo motor 17, the second laser rangefinder sensor 18, the second torque sensor 19, and the magnetic powder brake 20 are not limited; any model that meets the usage requirements is acceptable.
[0023] Furthermore, vertical rails 21 are fixedly connected at equal intervals on both sides of the base 1 and the lifting seat 5, and sliders 22 are fixedly connected on both sides of the outer wall of the lifting seat 5, with the outer wall of the vertical rails 21 and the sliders 22 slidably connected.
[0024] In the specific implementation process, it is worth noting that the cooperation between the base 1, the lifting seat 5, the vertical rail 21 and the slider 22 improves the stability of the lifting seat 5 during the lifting process, ensures that the lifting seat 5 moves smoothly in the vertical direction, and after stopping the movement, avoids the lifting seat 5 from shaking or deviating during the operation of the reducer 10, thereby further improving the detection accuracy and stability.
[0025] Furthermore, position correction indicator lights 23 are equidistantly installed on the top of the base 1, and the position correction indicator lights 23 are electrically connected to the controller 13;
[0026] In the specific implementation process, it is worth noting that the position correction indicator light 23 is used to show whether the reducer 10 and the second moving seat 15 have been accurately positioned. When the position correction indicator light 23 changes from red to green, it indicates that the reducer 10 or the second moving seat 15 has reached the preset position, so that the operator can understand the position of the reducer 10 or the second moving seat 15 according to the indicator light. The specific model of the position correction indicator light 23 is not limited, as long as it meets the usage requirements.
[0027] Furthermore, a speed sensor 24 is installed on the side of the first servo motor 2 and the first torque sensor 3, the second torque sensor 19 and the magnetic powder brake 20 that are close to each other. The speed sensor 24 is electrically connected to the controller 13.
[0028] In the specific implementation process, it is worth noting that the speed sensor 24 is installed on the outside of the connecting shaft between the first servo motor 2 and the first torque sensor 3, the second torque sensor 19 and the magnetic powder brake 20, respectively. It is used to measure the speed of the input shaft and output shaft of the reducer 10 in real time and transmit the detection data to the controller 13 in real time. The controller 13 calculates the reduction ratio of the reducer 10 accurately based on the received speed data and compares it with the design value to obtain the difference between the actual detection data and the design value of the reduction ratio of the reducer 10, so as to conduct a comprehensive and accurate evaluation of the performance of the reducer 10. The specific model of the speed sensor 24 is not limited, as long as it meets the usage requirements.
