Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor testing, in particular to a motor rotor simulation testing device. Background Art

[0002] The motor rotor is also a rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. The motor rotor is divided into the motor rotor and the generator rotor.

[0003] The motor rotor needs to be installed inside the motor for a rotation test before use, or directly installed inside a test device for a rotation test, so as to ensure that the motor rotor can operate normally after installation.

[0004] The above-mentioned existing technical solutions have the following defects: the motor rotor simulation test devices are mostly directly installed inside the motor for rotation testing, or are installed in a special test device for testing. Both of these test methods require sufficient positioning and installation of the motor rotor, but it is not convenient to quickly install and disassemble the motor rotor, which reduces the overall test efficiency. Utility Model Content

[0005] The utility model aims to provide a motor rotor simulation test device which is convenient for installing and disassembling the rotor and can quickly perform the test.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A motor rotor simulation test device comprises a power-on device and a rotor simulation device, wherein one end of the power-on device is electrically connected to a connector for branching, the outer side of the connector is electrically connected to a first connecting wire and a second connecting wire, the end of the first connecting wire away from the connector is electrically connected to a drive switch, the rotor simulation device is fixedly connected to a stator coil inside, the end of the second connecting wire away from the connector is electrically connected to the stator coil, and the upper and lower ends of the rotor simulation device are detachably connected to an upper cover and a lower cover for positioning.

[0008] By adopting the above technical solution, the upper cover and the lower cover are used to limit the bearings of the rotor body, so as to ensure that when the rotor body is inserted into the stator coil, the position of the rotor body is fixed, but the whole body can be rotated. The whole body is not only convenient for installing the rotor body, but also can perform a rotation test on the rotor body.

[0009] Further, a current display screen for displaying current and a voltage display screen for displaying voltage are fixedly connected in sequence from left to right at the front end of the energized device. A voltage adjustment knob for adjusting voltage is provided at the front end of the energized device, and the voltage adjustment knob is located below the voltage display screen.

[0010] By adopting the above technical solution, the current display screen and the voltage display screen can intuitively display the data during the overall test process, and at the same time, the voltage can be adjusted through the voltage adjustment knob, so as to ensure that the voltage can be adjusted as a whole to test the rotation of the rotor under different conditions.

[0011] Further, inside the rotor simulation device, there is a fixed cylinder body. An installation groove for installing a stator coil is opened inside the fixed cylinder body, and the inner wall of the installation groove is fixedly connected to the outer wall of the stator coil.

[0012] By adopting the above technical solution, the installation groove inside the fixed cylinder body is convenient for installing the stator coil. At the same time, a gap can be formed between the stator coil and the rotor body in the installation groove, so as to ensure that when the stator coil is energized, the rotor body can fully perform rotation tests.

[0013] Further, a rotor body is detachably connected inside the rotor simulation device. Bearings are fixedly connected to the upper and lower ends of the rotor body. A first positioning plate body is fixedly connected to the surface of the upper cover close to the fixed cylinder body, and a second positioning plate body is fixedly connected to the surface of the lower cover close to the fixed cylinder body. A positioning snap ring for clamping the outer ring of the bearing is fixedly connected inside the first positioning plate body and the first positioning plate body.

[0014] By adopting the above technical solution, the positioning snap ring can position the outer ring of the bearing, so as to ensure the fixed position of the rotor body. However, the rotor body can rotate inside the stator coil to ensure good overall test results.

[0015] Further, a grasping groove for a finger to pass through is opened on the side wall of the fixed cylinder body, and two groups of grasping grooves are symmetrically distributed about the center line of the fixed cylinder body.

[0016] By adopting the above technical solution, the grasping groove is convenient for taking and placing the upper cover, so as to facilitate the overall installation and disassembly of the rotor body, facilitate the overall test of the rotor body, and improve the overall test efficiency.

[0017] Further, a fixing screw is threadedly connected inside the lower cover. A fixing screw hole adapted to the fixing screw is opened on the surface of the fixed cylinder body close to the lower cover. The fixing screw passes through the lower cover and is threadedly connected to the fixing screw hole, and the fixing screw hole is located outside the installation groove.

[0018] By adopting the above technical solution, the lower cover can be stably installed, thereby ensuring that the whole can fully position the rotor body.

[0019] Further, there are two groups of positioning card holes provided on the shaft connecting sleeve, and the extension lines of the centers of the two groups of positioning card holes inside the shaft connecting sleeve are perpendicular to each other.

[0020] By adopting the above technical solution, two groups of positioning card holes are provided inside the shaft connecting sleeve, which is convenient for positioning the horizontal and vertical screen bodies and ensuring a good overall positioning display effect.

[0021] In summary, the beneficial technical effects of the present utility model are as follows:

[0022] 1. The stator coil is energized to make the rotor body rotate inside the stator coil, so that the whole can detect the rotation condition of the stator coil, thereby simulating and testing the condition of the rotor body inside the motor, producing the effect of rotor simulation test;

[0023] 2. The upper cover and the lower cover are used in cooperation to position the rotor body, and the upper cover is installed by pressing, which is convenient for installing and disassembling the rotor body, improving the overall test efficiency and producing the effect of rapid test;

[0024] 3. An energizing device with a voltage regulating knob is used to energize the coil, so as to ensure that the whole can adjust the rotor speed according to the situation, making the rotor body fully tested and producing the effect of full test. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Refer to Figure 1 , a motor rotor simulation test device, including a power-on device 1 and a rotor simulation device 2. One end of the power-on device 1 is electrically connected to a wire connector 3 for wire splitting. The outside of the wire connector 3 is electrically connected to a first connecting wire 4 and a second connecting wire 5. One end of the first connecting wire 4 away from the wire connector 3 is electrically connected to a drive switch 6. Inside the rotor simulation device 2, a stator coil 7 is fixedly connected. One end of the second connecting wire 5 away from the wire connector 3 is electrically connected to the stator coil 7. The upper and lower ends of the rotor simulation device 2 are detachably connected with an upper cover 8 and a lower cover 9 for positioning. The upper cover 8 and the lower cover 9 have the same specifications, and the upper cover 8 has a certain weight, so as to ensure sufficient positioning of the rotor body 23 and ensure a good overall rotation effect. At the front end of the power-on device 1, a current display screen 11 for displaying current and a voltage display screen 12 for displaying voltage are fixedly connected in sequence from left to right. At the front end of the power-on device 1, a voltage adjustment knob 13 for adjusting the voltage is provided. The voltage adjustment knob 13 is located below the voltage display screen 12. The power-on device 1 with the voltage adjustment knob 13 is an existing and common device, mainly used for adjusting the voltage and displaying data, so the specific model is not limited, which is convenient for overall data adjustment and data observation.

[0031] Refer to Figure 2 , inside the rotor simulation device 2, there is a fixed cylinder body 21. Inside the fixed cylinder body 21, an installation groove 22 for installing the stator coil 7 is opened. The inner wall of the installation groove 22 is fixedly connected to the outer wall of the stator coil 7. The stator coil 7 is a structure formed by multiple groups of wires installed inside the installation groove 22 to ensure that the rotor body 23 can rotate inside the stator coil 7. Inside the rotor simulation device 2, a rotor body 23 is detachably connected. Bearings 24 are fixedly connected to the upper and lower ends of the rotor body 23. A first positioning plate body 25 is fixedly connected to the surface of the upper cover 8 close to the fixed cylinder body 21. A second positioning plate body 26 is fixedly connected to the surface of the lower cover 9 close to the fixed cylinder body 21. A positioning snap ring 27 for clamping the outer ring of the bearing 24 is fixedly connected inside the first positioning plate body 25 and the first positioning plate body 25. The shape and size of the positioning snap ring 27 and the outer ring of the bearing 24 are adapted to each other. In this design, only one situation is proposed, and other clamping structures can also be used for fixing positions. The main purpose is to position and fix the outer ring of the bearing 24, and the specific structure can be adjusted according to the situation. The positioning snap ring 27 can be used as a structure to clamp and position the outer ring of the bearing 24, or the outer ring of the bearing 24 can be directly positioned and fixed by pressing with weight.

[0032] Refer to Figure 3, a grasping groove 28 for fingers to pass through is formed on the side wall of the fixed cylinder body 21. There are two groups of grasping grooves 28 symmetrically distributed about the center line of the fixed cylinder body 21. The grasping grooves 28 facilitate the overall grasping and installation of the upper cover 8, thereby facilitating the installation and disassembly of the rotor body 23, increasing the overall test efficiency. A fixing screw 91 is threadedly connected inside the lower cover 9. A fixing screw hole 29 adapted to the fixing screw 91 is formed on the side of the fixed cylinder body 21 close to the lower cover 9. The fixing screw 91 passes through the lower cover 9 and is threadedly connected to the fixing screw hole 29. The fixing screw hole 29 is located outside the installation groove 22. The stable fixation of the lower cover 9 can increase the positioning effect of the rotor body 23, thereby facilitating the overall test.

[0033] The implementation principle of this embodiment is as follows: First, the lower cover 9 is stably installed by threading the fixing screw 91 through the lower cover 9 and connecting it to the fixing screw hole 29. Then, the rotor body 23 is placed inside the stator coil 7. Next, the upper cover 8 is covered, so that the first positioning plate body 25 and the second positioning plate body 26 inside the upper cover 8 and the lower cover 9 can fully position the rotor body 23, and ensure that the positioning snap ring 27 clamps and positions the outer ring of the bearing 24, ensuring that the rotor body 23 can rotate inside the stator coil 7. Then, the stator coil 7 is energized through the power-on device 1. The magnet inside the rotor body 23 rotates when the surrounding coil is energized, and the rotation state of the rotor body 23 is tested. The voltage of the power-on device 1 is adjusted through the voltage adjustment knob 13, facilitating the overall adjustment of data and the observation of data, and completing the rotational simulation test of the rotor body 23.
