Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, and particularly relates to a performance testing system for a nano rare earth disk direct drive synchronous permanent magnet motor. Background Art

[0002] Nano rare earth materials are materials with special structures and properties, and their grain sizes are at the nano level. Compared with traditional materials, nano rare earth materials have a higher surface area and more grain boundaries, thus making them have more excellent electromagnetic characteristics and thermal stability. Therefore, a coreless disk motor made of nano rare earth materials can achieve higher power density and efficiency. The coreless disk motor made of nano rare earth materials adopts a disk structure. Compared with traditional core motors, it has a smaller size and lighter weight, which makes the coreless disk motor made of nano rare earth materials have greater advantages in occasions with limited space, such as applications in unmanned aerial vehicles, mechanical production, medical equipment and other fields.

[0003] In order to enable the produced motor to achieve various preset functions, it is necessary to conduct sampling tests after the motor is manufactured, simulate various actual working conditions, and thus efficiently and accurately verify and test the actual performance of the motor. The problems that occur during the motor performance test can be optimized and solved in a timely manner to avoid the motors produced in batches failing to meet the preset requirements, resulting in greater losses, and to detect whether the performance of the motor meets the qualified requirements. However, although the existing motor detection devices can detect the performance of the motor, the operation process of the existing motor performance detection devices is too complex and the cost is relatively high. It is necessary for the staff to transfer the motor between multiple detection devices to complete the multiple function detections of the motor. This detection method not only causes slow detection efficiency but also increases the labor intensity of the staff. Summary of the Invention

The installation end of the electric extension rod 25 faces the moving plate 11, and the installation end of the electric extension rod 25 is connected to the lifting slider 15. A rotating motor 18 is installed on the top of the connecting rod 16. The output end of the rotating motor 18 movably penetrates through the top of the connecting rod 16 and is connected to the top of the rotating rod 17.

[0042] As a technical optimization solution of the present invention, a first slot 29 is provided at one end of the rotating rod 17 away from the connecting rod 16. A spring 30 is installed at the bottom end of the inner wall of the first slot 29. One end of the movable rod 19 close to the rotating rod 17 is slidably installed inside the first slot 29.

When the rotating rod 17 rotates to the side where the fixed block 20 faces the motor output shaft, the connecting rod 16 is extended by the electric extension rod 25, so that the two clamping blocks 21 abut against the outside of the motor output shaft. Then, the moving plate 11 moves away from the motor. During the process that the moving plate 11 moves away from the motor, the sliding block 28 slides inside the fixed block 20 and squeezes the telescopic rod 27. The telescopic rod 27 squeezes the pressure sensor 26. The pressure sensor 26 transmits the pressure value to the background control system. The moving plate 11 continues to move until the measured pressure value reaches the preset pressure value. During this period, observe the change of the motor output shaft. By this operation method, the tensile capacity of the motor output shaft can be detected.

[0044] When the present invention is in use, all the devices used in this device are electrically driven devices. The electrical devices in this device are all powered by connecting to a power source through wires. In this device, the electrical devices in the device are controlled by setting up a control system. The opening 4 is connected to an air pump preset outside the device through a conduit, and a control valve is provided at the connection between the opening 4 and the conduit. The top of the protective cover 2 is sealed by the top cover 3. Three manipulators are preset outside the upper part of the protective cover 2, one of which is a feeding manipulator, and the other two are good product discharging manipulators and defective product discharging manipulators. The manipulators are existing mature technologies, so no more elaboration will be made on them. The bottom of the top cover 3 is provided with lighting equipment and a camera for recording the testing process. The rotational speed sensor 24, temperature sensor 39, air pressure sensor 40 and sound sensor 41 used in this device are all existing mature technologies, so no more elaboration will be made on them. The motor detected by this device is a nano rare earth disk direct drive synchronous permanent magnet motor. The proposed structure of this motor reduces the use of rare earth materials in permanent magnet motors, reduces the loss of no-load back electromotive force before and after demagnetization, and improves the anti-demagnetization performance of the motor.

[0045] When the device is in use, the electric lifting rod 43 drives the top cover 3 to extend upward to a preset height position, and the rotating motor 44 drives the top cover 3 to rotate to a preset position so that the top cover 3 does not affect the use of the manipulators preset outside the device. Subsequently, the two clamping rods 9 slide through the first electric slider 8 in the first chute 7 to a preset position. Subsequently, the feeding manipulator lowers the clamped motor. When the motor is lowered to the preset position, the two clamping rods 9 move closer to each other. The two clamping rods 9 are respectively located on both sides of the motor. When the clamping rods 9 move to the preset position, the motor is clamped and fixed by the clamping plate 10. Subsequently, the motor is powered by connecting to the motor through a power supply mechanism preset inside the device. The manipulator makes a reset movement away from the device, and the top cover 3 makes a reset movement and abuts against the top of the protective cover 2 again to seal the protective cover 2.

[0046] The moving plate 11 slides through the second electric slider 13 in the second chute 12 to a preset position. Subsequently, the electric extension rod 25 drives the connecting rod 16 to move closer to the motor until the roller 22 abuts against the output shaft of the motor. Subsequently, the motor is started so that the output shaft of the motor starts to rotate. During the rotation of the output shaft of the motor, the roller 22 is driven to rotate. The rotation of the roller 22 drives the connecting shaft 23 to rotate synchronously. Subsequently, the rotational speed of the connecting shaft 23 is detected by the rotational speed sensor 24, and the detected rotational speed value is transmitted to the background control system. The rotational speed detection of the motor is completed through this operation method.

[0047] When detecting the rotational speed of the motor, the vibration generated by the output shaft of the motor is transmitted to the movable rod 19 through the roller 22. The movable rod 19 sways inside the first slot 29. When the movable rod 19 sways, the vibration sensor 33 detects the sway value of the movable rod 19 and transmits it to the background control system. Subsequently, the rotating motor 18 drives the rotating rod 17 to rotate, causing the rotating rod 17 to rotate to a state perpendicular to the connecting rod 16. Then, the telescopic slider 36 slides in the telescopic chute 35 to drive the telescopic block 31 to move into the third slot 34 until the roller 22 moves into the third slot 34. Subsequently, the lifting slider 15 moves up and down in the lifting chute 14 in combination with the movement of the moving plate 11, enabling the end of the movable rod 19 to abut against multiple positions of the motor. At this time, when the motor is in use, the vibration generated outside the motor can be detected by the vibration sensor 33, and the vibration value is transmitted to the background control system for comparison. Through this operation method, the vibration detection of the motor can be completed; by driving the rotating rod 17 to rotate in different directions by the rotating motor 18 and combining the movement of the moving plate 11 in the protective cover 2, the device can detect the vibration on both sides of the motor, and the accuracy of the detection result of the device can be increased through this operation method.

[0048] The rotating rod 17 rotates to the side where the fixed block 20 faces the output shaft of the motor. The electric extension rod 25 drives the connecting rod 16 to extend, causing the two clamping blocks 21 to abut against the outside of the output shaft of the motor. Subsequently, the moving plate 11 moves away from the motor. During the process of the moving plate 11 moving away from the motor, the sliding block 28 slides inside the fixed block 20 and squeezes the telescopic rod 27. The telescopic rod 27 squeezes the pressure sensor 26, and the pressure sensor 26 transmits the pressure value to the background control system. The moving plate 11 continues to move until the measured pressure value reaches the preset pressure value. During this period, observe the change of the output shaft of the motor. Through this operation method, the tensile capacity of the output shaft of the motor can be detected.

[0049] During the detection of the motor, the temperature sensor 39 can detect the temperature of the motor during operation. And by increasing the rated voltage of the motor to make the motor operate under load and then detecting the temperature of the motor, the temperature rise test of the motor can be completed; the sound sensor 41 can detect the noise of the motor during operation. The air pump connected to the opening 4 starts to inflate and pressurize the inside of the protective cover 2. The pressure sensor 40 can detect the pressure inside the protective cover 2. When the pressure value inside the protective cover 2 reaches the preset size, the valve installed at the opening 4 closes. At this time, observe the operating state of the motor under the preset air pressure, and conduct the above-mentioned vibration detection, rotational speed detection and other functional detections on the motor, and compare with the values detected under the normal working state. Through this operation method, the detection of the operating state of the motor under high-pressure environment can be completed.

[0050] Start the heating plate 6. The interior of the protective cover 2 can be heated through the heating plate 6. At this time, the temperature inside the protective cover 2 can be detected by the temperature sensor 39. During the process of heating the interior of the protective cover 2 by the heating plate 6, by driving the motor to move left and right through the clamping rod 9, the temperature inside the protective cover 2 can be made more uniform, enhancing the heating effect of the heating plate 6. When the temperature inside the protective cover 2 rises to the preset temperature, then perform the above-mentioned multiple function detections on the motor, and compare the detection results with the detection data during normal operation. Through this operation method, the detection of the high-temperature working state of the motor can be completed.

[0051] After the detection is completed, the top cover 3 moves upward to the preset position. Subsequently, start the air pump connected to the opening 4. At this time, by quickly inflating the interior of the protective cover 2 through the air pump, the hot air inside the protective cover 2 can be quickly discharged, and the motor and various devices in this device can be quickly cooled down, increasing the convenience of using the device.

[0052] When the device discharges the motor, the qualified motor moves to the lower part of the good-product discharging manipulator through the clamping rod 9 for discharging, and the unqualified motor moves to the lower part of the defective-product discharging manipulator through the clamping rod 9 for discharging. Through this operation method, the classified discharging of the motor can be completed, increasing the convenience of using the device.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
