Description

Technical Field

[0001] This utility model relates to the technical field of permanent magnet drive testing equipment, and in particular to a permanent magnet drive aging test device. Background Technology

[0002] As industrial equipment demands increasing operational stability, the long-term reliability of permanent magnet drives is receiving growing attention. During the manufacturing process, aging tests are conducted to simulate the drive's operation under long-term load conditions, detecting potential aging issues such as magnet decay, internal bearing wear, and deterioration of winding insulation. During equipment maintenance, aging tests are also regularly performed on long-serving permanent magnet drives to assess their remaining lifespan and prevent sudden aging failures that could lead to production line shutdowns and economic losses. Therefore, aging testing has become a crucial step in ensuring the quality of permanent magnet drives and the safe operation of industrial equipment.

[0003] Existing permanent magnet drive aging test devices mostly rely on manual handling or simple brackets to support the permanent magnet drive, manually adjusting its relative position with the detection sensor and load motor. Due to the lack of a precise positioning and guiding structure, it is difficult to ensure that the central axis of the permanent magnet drive is perfectly aligned with the central axis of the detection sensor and load motor, which can easily lead to transmission backlash or force misalignment. This can cause distortion of key parameters such as speed and torque collected by the detection sensor, failing to accurately reflect the aging state of the drive, and may even damage the sensor interface or drive output shaft due to improper docking. Moreover, most of these devices are dedicated equipment designed for specific drive models and cannot flexibly adapt to different specifications of the test objects. Enterprises need to purchase multiple test devices for different drive models, significantly increasing equipment procurement and maintenance costs, especially for small and medium-sized manufacturing enterprises or maintenance units, where the equipment investment pressure is significant. Therefore, we propose a permanent magnet drive aging test device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an aging test device for permanent magnet drives to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A permanent magnet actuator aging test device includes: a test platform, a test sensor, a load motor, and a permanent magnet actuator body. The test platform has a T-shaped rail, four sets of limit rods, two sets of brackets, a first mounting platform, a second mounting platform, a display, and a controller fixedly mounted on its top. The test sensor is mounted on the first mounting platform, and the load motor is mounted on the second mounting platform. A lifting platform is slidably mounted on the outer side of the four sets of limit rods. A bidirectional lead screw is rotatably mounted inside the lifting platform. Two sets of moving plates are threadedly connected to the outer side of the bidirectional lead screw. Clamping plates are fixedly mounted on corresponding sides of the two sets of moving plates. The permanent magnet actuator body is mounted on the lifting platform and abuts against the two sets of clamping plates. Two sets of moving seats are slidably mounted on the outer side of the T-shaped rail. A transmission rod is hinged between the two sets of moving seats and the bottom of the lifting platform. A bidirectional lead screw is rotatably mounted inside the two sets of brackets.

[0006] Preferably, the two sets of movable plates are slidably mounted on the top of the lifting platform, the two sets of movable seats are threadedly connected to the outside of the bidirectional lead screw, and the two ends of the sensor are respectively connected to the output end of the permanent magnet drive body and the output end of the load motor.

[0007] Preferably, the lifting platform has four sets of limiting grooves inside, and the four sets of limiting grooves are adapted to the corresponding limiting rods.

[0008] Preferably, the top of the lifting platform is provided with two sets of guide grooves, and the two sets of moving plates are slidably installed in the corresponding guide grooves.

[0009] Preferably, a motor is fixedly installed on one side of the lifting platform, and one end of the bidirectional lead screw is fixedly installed on the output end of the motor.

[0010] Preferably, one side of one of the brackets is fixedly mounted with a second motor, and one end of the second bidirectional lead screw is fixedly mounted on the output end of the second motor.

[0011] In this invention, a permanent magnet drive aging test device is described. The operator connects the two ends of the detection sensor to the output ends of the permanent magnet drive body and the load motor, respectively, forming a complete power transmission and signal monitoring circuit. The controller sends a start command to the permanent magnet drive body, driving it into working condition. Simultaneously, it controls the load motor to operate according to preset aging test parameters, simulating the load environment of the drive in actual applications. The permanent magnet drive body continues to operate under the reverse load of the load motor. The controller collects key operating data of the drive in real time through the detection sensor. During the test, the controller continuously monitors according to a preset test cycle to ensure coverage of the typical aging cycle of the drive. The detection sensor converts the collected real-time operating data into electrical signals. The processed test data and analysis results are displayed on a monitor, allowing the operator to intuitively view the aging status of the drive. This utility model features a reasonable structural design. A motor drives a bidirectional lead screw to rotate inside the lifting platform. Since two sets of moving plates are threadedly connected to the bidirectional lead screw, these plates move relative to each other within the guide groove until the two sets of clamps are tightly abutted against both sides of the permanent magnet actuator body. This fixes the actuator body horizontally, preventing positional shifts due to vibration during testing. A second motor then drives a bidirectional lead screw to rotate inside two sets of supports. These moving seats are threadedly connected to the bidirectional lead screw, causing them to slide relative to each other outside the T-rail. This, in turn, causes the transmission rod to swing. Because the transmission rod is hinged to the bottom of the lifting platform and the moving seats, the angle between the transmission rod and the horizontal direction changes, pushing the lifting platform upwards along the limit rod until the output end of the permanent magnet actuator body is perfectly aligned with the output ends of the detection sensor and the load motor. This ensures the actuator's central axis is consistent with the baseline for subsequent height adjustment. This design is particularly suitable for batch testing scenarios, significantly improving test preparation efficiency and avoiding instability in fixing results due to differences in manual operation. It also enhances test consistency. Attached Figure Description

The test sensor 3 is mounted on the mounting platform 1 2, and the load motor 5 is mounted on the mounting platform 2 4. A lifting platform 9 is slidably mounted on the outer side of the four sets of limit rods 8. A bidirectional lead screw 12 is rotatably mounted inside the lifting platform 9. Two sets of moving plates 13 are threadedly connected to the outer side of the bidirectional lead screw 12. Clamping plates 14 are fixedly mounted on corresponding sides of the two sets of moving plates 13. The permanent magnet actuator body 10 is mounted on the lifting platform 9 and abuts against the two sets of clamping plates 14. Two sets of moving seats 17 are slidably mounted on the outer side of the T-shaped rail 16. A transmission rod 21 is hinged between the two sets of moving seats 17 and the bottom of the lifting platform 9. A bidirectional lead screw 20 is rotatably mounted inside the two sets of brackets 18.

[0016] In this embodiment, two sets of movable plates 13 are slidably mounted on the top of the lifting platform 9, and two sets of movable seats 17 are threadedly connected to the outside of the bidirectional lead screw 20. The two ends of the sensor are respectively connected to the output end of the permanent magnet driver body 10 and the output end of the load motor 5.

[0017] In this embodiment, the lifting platform 9 has four sets of limiting grooves inside, and the four sets of limiting grooves are adapted to the corresponding limiting rods 8.

[0018] In this embodiment, the top of the lifting platform 9 is provided with two sets of guide grooves 15, and two sets of moving plates 13 are slidably installed in the corresponding guide grooves 15.

[0019] In this embodiment, a motor 11 is fixedly installed on one side of the lifting platform 9, and one end of the bidirectional lead screw 12 is fixedly installed on the output end of the motor 11.

[0020] In this embodiment, a motor 19 is fixedly installed on one side of one set of brackets 18, and one end of a bidirectional lead screw 20 is fixedly installed on the output end of the motor 19.

[0021] In this embodiment, during use, by connecting the display 6, controller 7, load motor 5, motor 11, motor 2 19 and detection sensor 3 on the detection station 1 to the power supply, the controller 7 automatically performs a system self-test to confirm that the circuit connection of each electrical component is normal and there is no fault signal feedback. The operator then places the permanent magnet actuator body 10 to be tested on the lifting platform 9, positioned between the two sets of clamping plates 14. Drive motor 11 drives the bidirectional lead screw 12 to rotate inside the lifting platform 9. Since the two sets of moving plates 13 are threadedly connected to the bidirectional lead screw 12, the two sets of moving plates 13 drive the corresponding clamping plates 14 to move relative to each other within the guide groove 15 until the two sets of clamping plates 14 are tightly abutted against both sides of the permanent magnet actuator body 10, thus fixing the actuator body horizontally and preventing positional displacement due to vibration during testing. Then, drive motor 11... 9 drives the bidirectional lead screw 20 to rotate inside the two sets of brackets 18. The two sets of moving seats 17 are connected to the bidirectional lead screw 20 by threads, thereby driving the two sets of moving seats 17 to slide relative to each other on the outside of the T-shaped rail 16, which in turn drives the transmission rod 21 to swing. Since the transmission rod 21 is hinged to the bottom of the lifting platform 9 and the moving seat 17, the angle between the transmission rod 21 and the horizontal direction changes, thereby pushing the lifting platform 9 to slide upward along the limit rod 8 until the output end of the permanent magnet drive body 10 is completely aligned with the height of the detection sensor 3 and the load motor 5. The operator connects the two ends of the detection sensor 3 to the output ends of the permanent magnet drive body 10 and the load motor 5, respectively, forming a complete power transmission and signal monitoring loop. The controller 7 sends a start command to the permanent magnet drive body 10 to drive it into the working state, and at the same time controls the load motor 5 to run according to the preset aging test parameters to simulate the load environment of the drive in actual application. The permanent magnet drive body 10 runs continuously under the reverse load of the load motor 5. The controller 7 collects the key operating data of the drive in real time through the detection sensor 3. During the test, the controller 7 will continuously monitor according to the preset test cycle to ensure that the typical aging cycle of the drive is covered. The detection sensor 3 converts the collected real-time operating data into electrical signals. The processed test data and analysis results are displayed on the display 6, which allows the operator to intuitively view the aging status of the drive.
