[0036] See appendix Figures 1 to 5 This paper presents an illustrative embodiment of the electric servo motor inspection instrument proposed in this utility model. The electric servo motor inspection instrument includes a servo motor test bench 1 and an electrical control box 2.

[0037] The servo motor test bench 1 includes a housing 11, a loading module 12, a testing module 13, and a test module 14. The top of the housing 11 is equipped with a tabletop fixing plate 111, which supports and bears the loading module 12, the testing module 13, and the test module 14. The housing 11 is a square steel structure, characterized by high strength and rigidity, possessing high strength and load-bearing capacity, capable of withstanding significant pressure, tension, and bending forces, and able to withstand various loads generated during the operation of the servo motor test bench 1, ensuring its normal operation.

[0038] In this embodiment, the platform fixing plate 111 is made of 15mm thick Q235 steel plate, and the entire housing 11 is also made of Q235 steel plate. The Q235 steel plate has moderate strength, sufficient to ensure that the servo motor test bench 1 will not deform under normal use. Furthermore, Q235 steel plate is a widely produced and used common carbon structural steel with abundant raw material sources and mature production processes, which can save material costs while ensuring structural safety.

[0039] In this embodiment, the front end of the housing 11 is provided with two doors, which can be used to install various components for testing, such as torque, speed and power acquisition instruments, tension controllers and power supply components, etc., inside the housing 11. It can also store equipment cables and testing accessories, making maintenance and use convenient.

[0040] For easy movement, in this embodiment, the housing 11 also includes a handle 112 and casters 113. The handle 112 is located on the side of the housing 11. The casters 113 are located at the bottom of the housing 11. To ensure stable movement of the servo test bench 1, four casters 113 are provided, located at the four corners of the bottom of the housing 11. When the servo test bench 1 needs to be moved, the handle 112 provides support for the operator, thereby better controlling the movement of the servo test bench 1, ensuring safety and reliability. The casters 113 can be selected as braked casters, which provide both ease of movement and braking function. When the servo test bench 1 is moved to the designated working point, the wheels can be locked by the braking device to ensure that the servo test bench 1 will not move unexpectedly during operation, improving the stability and safety of the equipment.

[0041] A loading module 12 is mounted on the platform mounting plate 111 and is used to provide loading force. A test module 13 is mounted on the platform mounting plate 111 and is connected to the loading module 12. The test module 13 is used to inspect the electric servo motor. A test module 14 is mounted on the platform mounting plate 111 and is connected to the test module 13. The test module 14 includes an electric servo motor 141 and a DC motor driver for driving the electric servo motor 141. In this embodiment, the electric servo motor 141 can be a DCD-41C / 41D / 41E type control servo motor, a DCD-21 / 21A / 21B type control servo motor, or a DTD-2 trim servo motor.

[0042] The electrical control box 2 can be placed on the servo motor test bench 1 during use and can be removed and stored separately when not in use. The electrical control box 2 contains an embedded industrial control computer 21 based on the Windows operating system. The embedded industrial control computer 21 is connected to the servo motor test bench 1 to output commands to control the servo motor test bench 1 to check the electric servo motor 141 and collect and display test data. In this embodiment, the electrical test box 2 is a military-grade portable case, which features shockproof, moisture-proof, corrosion-proof, aging-resistant, impact-resistant, and long-lasting characteristics.

[0043] The servo test bench 1 also includes an auxiliary module 15, which includes a first coupling 151 and a second coupling 152. The first coupling 151 is used to connect the loading module 12 and the test module 13. In this embodiment, the first coupling 151 and the second coupling 152 are selected as flexible couplings, which can protect the sensor shaft from damage, improve the sensor detection accuracy, and extend its service life.

[0044] The loading module 12 includes a magnetic powder brake 121 and a constant current source controller. The constant current source controller provides excitation current so that the magnetic powder brake 121 outputs torque. The loading force is provided by the magnetic powder brake 121, and the magnitude of the damping force is controlled by setting the current to meet the test loading force requirements.

[0045] The magnetic powder brake 121 is a transmission element that uses magnetic powder as a medium to form a magnetic powder chain, thereby transmitting torque when energized. It mainly consists of an inner rotor, an outer rotor, an excitation coil, and magnetic powder. When the coil is not energized, the moving rotor rotates, and under the action of centrifugal force, the magnetic powder is thrown onto the inner wall of the driving rotor. There is no contact between the magnetic powder and the driven rotor, and the driving rotor is in an idling state. After a DC power supply is connected, an electromagnetic field is generated. Under the action of magnetic lines of force, the magnetic powder in the working medium forms a magnetic powder chain, connecting the inner and outer rotors to achieve the purpose of transmitting and braking torque. The output torque of the magnetic powder brake 121 can be adjusted by regulating the excitation current. Using this principle, different loads can be simulated.

[0046] Test module 13 includes a torque-speed sensor 131 and an encoder 132. The torque-speed sensor 131 is connected to the magnetic powder brake 121 via a first coupling 151, and the torque-speed sensor 131 is connected to the encoder 132 via a second coupling 152. It can automatically perform off-center and on-center function and performance checks of various types of electric servos under various conditions based on system performance indicators, as well as various performance checks under clutch on / off and slippage conditions.

[0047] The auxiliary module 15 also includes a gear mechanism, which connects the torque-speed sensor 131 and the electric servo motor 141 to transmit the torque output by the magnetic powder brake 121 to the electric servo motor 141. The gear mechanism is used to transfer the torque output from the drum of the electric servo motor 141 to the shaft of the testing equipment via a gear mold, facilitating the installation of the electric servo motor 141. Furthermore, by adjusting the gear torque, the magnetic powder brake can output an adjustable damping torque of 0–1200 N.

[0048] The embedded industrial control unit 21 includes a touch screen 211 and, sequentially arranged next to the touch screen 211, an electric servo motor cable port 212, a servo motor test bench cable port 213, a power interface 214, a power switch 215, and an emergency stop switch 216. In this embodiment, the servo motor test bench 1 mainly realizes the off-position loading test of the servo motor. When the electric servo motor 141 needs to be tested off-position, the electric servo motor 141 can be installed and fixed on the dedicated base of the servo motor test bench 1, and connected to the load loading part of the servo motor test bench 1 through the connecting shaft to complete the testing of physical parameters such as torque, speed, rotation angle, and clutch slippage force. The electrical control box 2 can realize the measurement of electrical parameters, and detect electrical parameters such as input voltage, input current, operating voltage, potentiometer zero point voltage, loss current, clutch engagement and release voltage of the electric servo motor 141. During the off-position test, the electrical control box 2 can control the servo motor test bench 1 to provide various different load forces to the electric servo motor 141, and measure the speed, torque, and rotation angle of the electric servo motor 141 under load. During in-situ testing, static electrical parameters of the electric servo motor 141 can be measured simply by connecting the electrical control box 2 to the electric servo motor 141 via a test cable. The touch screen 211 installed in the electrical control box 2 allows for touch control, simplifying the operation of the human-machine interface and greatly reducing the workload of maintenance personnel.

[0049] In the above illustrative embodiment, the electric servo motor inspection instrument includes a servo motor test bench and an electrical control box. It is simple, reliable, easy to operate, and highly integrated and automated, enabling personnel to conveniently and quickly complete performance testing of various models of electric servo motors. The electrical control box contains an embedded industrial control computer based on a Windows operating system, which can directly use various professional testing software to perform in-situ and off-site verification of various types of electric servo motors. This enriches the servo motor testing methods, broadens the application scenarios of the electric servo motor inspection instrument, and improves the efficiency of aircraft maintenance work.
