[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] See also Figures 1 to 11 The present invention proposes a high-speed operation test device for a motor rotor, comprising a base 1, a fixed platform 2 is provided on the base 1, a test bench 3 is installed on the fixed platform 2, a rotor mounting mechanism that can move in the lateral direction of the test bench 3 is provided on the test bench 3, a stator mounting seat 4 that matches the rotor after the rotor mounting mechanism moves in the lateral direction is also installed on the fixed platform 2, at least two stator coils 5 are sequentially sleeved in the stator mounting seat 4, a driving mechanism for driving the rotor mounting mechanism to move into the stator mounting seat 4 is provided on the test bench 3, a stator switching mechanism for switching the stator coils 5 is installed at the tail end of the stator mounting seat 4, and a partition mechanism for isolating the stator mounting seat 4 and the stator switching mechanism is installed on the stator mounting seat 4.

[0036] The rotor mounting mechanism can be used to clamp rotors of different sizes, and the driving mechanism moves the rotor into the stator coil 5 for testing. When clamping a larger rotor, the rotor mounting mechanism drives the stator switching mechanism when it moves to the base mounting seat, so that the smaller stator coil 5 is moved out of the stator mounting seat 4, so that the stator in the stator mounting seat 4 matches the rotor size, thereby avoiding a gap between the rotor and the stator coil 5 that is too large, resulting in a reduction in the torque of the magnetic field on the rotor and failure to achieve normal test results, thereby improving the accuracy of the test results, or increasing the current and enhancing the magnetic field effect, but requiring more energy consumption. At the same time, when the rotor mounting mechanism moves into place, it drives the partition mechanism to isolate the stator mounting seat 4 and the removed stator coil 5, thereby avoiding mutual influence between different stator coils 5.

[0037] In one embodiment, if Figure 1 As shown, three stator coils 5 are provided, and the stator coils 5 are sequentially sleeved in the stator coil 5 with a larger diameter according to their diameters, and the outer layer of each stator coil 5 is sequentially provided with insulating material and electromagnetic shielding material.

A sliding block 9 is slidably connected therein, and one end of the sliding block 9 located in the mounting groove 7 is fixedly connected to a fixed block 10, one end of one sliding block 9 away from the fixed block 10 is fixedly connected to a connecting rod 11, and one end of the connecting rod 11 is fixedly connected to a pushing rod 12, a rotating disk 13 is rotatably connected in the mounting groove 7, and a first spiral groove 14 is provided on the rotating disk 13, and a protrusion matching the first spiral groove 14 is provided on the sliding block 9, which is used to drive the sliding block 9 to move radially along the rotating disk 13.

[0039] The rotor mounting mechanism is similar to the principle of a three-jaw chuck, and is common knowledge to those skilled in the art. The structure is not fully shown in the figure and will not be described in detail herein. When the rotating disk 13 rotates, the sliding block 9 is driven to move, thereby driving the fixed block 10 to move to clamp the rotor. At the same time, the sliding block 9 moves, driving the connecting rod 11 to move, thereby driving the pushing rod 12 to move, so as to complete the switching and isolation of different stator coils 5.

[0046] When clamping a rotor of smaller size, during the process of the rotor moving to the stator mounting seat 4, the push rod 12 will not conflict with the push plate 47 and the abutment rod 41; when clamping a rotor of medium size, during the process of the rotor moving to the stator mounting seat 4, the push rod 12 conflicts with the push plate 47 and will not conflict with the abutment rod 41. When the push rod 12 moves, it drives the push plate 47 to move, thereby driving the drive block 45 to move, and then driving the drive ball 46 to move. The drive ball 46 drives the rotating shaft 2 43 to rotate, thereby driving the driving gear 42 to rotate, and then driving the ring gear 30 to rotate. The ring gear 30 drives the first gear 23 to rotate, thereby driving the second threaded rod 22 to rotate, and then driving the second slider 24 to rotate. The second slider 24 drives the first connecting block 25 to move, thereby driving the small stator coil 5 to move into the storage seat 19, so that the rotor and the stator coil 5 match in size; when clamping a rotor of larger size, during the process of the rotor moving to the stator mounting seat 4, the push rod 12 conflicts with the push plate 47 and the abutment rod The second rotating rod 39 drives the rotating ring 37 to rotate, thereby driving the first rotating rod 38 to rotate, and then driving the interlocking wheel 31 to move onto the connecting sleeve 34, so that the interlocking wheel 31 and the connecting sleeve 34 are connected, so that the ring gear 30 rotates, and when the second gear 27 is driven to rotate, the fixing rod 33 is driven to rotate, thereby driving the interlocking wheel 31 to rotate, and then driving the connecting sleeve 34 to rotate, and the connecting sleeve 34 drives the third threaded rod 26 to rotate, thereby driving the third slider 28 to rotate, and then driving 29 to move, and at the same time, the ring gear 30 rotates to drive the first gear 23 to rotate, and the same as the above process, the smaller stator coil 5 and the larger stator coil 5 are moved into the storage seat 19 at the same time, so that the rotor and the stator coil 5 are matched in size, and the gap between the rotor and the stator coil 5 is avoided to be too large, resulting in a reduction in the torque generated by the magnetic field on the rotor, and the normal test result cannot be achieved.

[0047] See also Fig.10 and Fig.11 The partition mechanism includes a first partition plate 49 slidably connected to the stator mounting seat 4, a second partition plate 50 is slidably connected outside the first partition plate 49, a support rod 51 for supporting the first partition plate 49 and the second partition plate 50 is slidably connected inside the stator mounting seat 4, and a push block 52 is slidably connected to one side of the support rod 51.

[0048] The first partition plate 49 and the second partition plate 50 are both made of electromagnetic shielding materials and insulating materials. When clamping a medium-sized rotor, the push rod 12 pushes the support rod 51 to move, and the support rod 51 no longer supports the first partition plate 49, causing the first partition plate 49 to fall, which will isolate the stator mounting seat 4 from the smallest stator coil 5 to avoid mutual influence between different stator coils 5; when clamping a larger rotor, the push rod 12 pushes the push block 52 to move, driving the support rod 51 to move, so that the support rod 51 no longer supports the first partition plate 49 and the second partition plate 50, causing the first partition plate 49 and the second partition plate 50 to fall, isolating the stator mounting seat 4 from the removed stator coil 5 to avoid mutual influence between different stator coils 5.

[0049] See also Figure 4 The width of the first partition plate 49 is smaller than the distance between the two second connection blocks 29, so as to prevent the first partition plate 49 from being blocked by the second connection blocks, so that it can fall normally.

[0050] See also Figure 5 The push rod 12 moves along the axial direction of the rotating shaft 43, and the push rod 12 pushes the support rod 51 and the push block 52 in a timely manner. The support rod 51 and the push block 52 are located above the push plate 47, so that the push rod 12 can push the push plate 47, the support rod 51 and the push block 52 respectively without affecting each other.
