[0023] This utility model provides, for example Figures 1-4The permanent magnet motor rotor installation tool shown includes an operating table 1 with a support frame 2 fixedly connected to the top, and the support frame 2 is V-shaped.

[0024] In practical use, the rotor is placed on the support frame 2. Since the support frame 2 is V-shaped, it is suitable for rotors with different outer diameters, which facilitates the installation of the permanent magnet motor rotor nut locking operation.

[0025] To fix the rotor, a movable groove 3 is provided on both sides of the support frame 2. The movable groove 3 is rectangular. A sliding frame 4 is slidably arranged inside the movable groove 3. A movable block 7 is slidably arranged inside the sliding frame 4. The movable block 7 slides inside the sliding frame 4, and the movable block 7 uses the pressing component to press and fix the permanent magnet motor rotor from top to bottom.

[0026] In a specific configuration, the extrusion assembly includes a sliding channel 10 and a clamping plate 11. The sliding channel 10 is opened on the moving block 7, and the clamping plate 11 is slidably disposed inside the sliding channel 10. A rubber pad can be provided on the outside of the clamping plate 11 to reduce wear.

[0027] Since the clamping plate 11 is slidably disposed inside the sliding channel 10, the clamping plate 11 can be removed or its length inserted into the V-groove of the support frame 2 can be adjusted, making it easier to place the rotor on the support frame 2.

[0028] In actual use, remove the clamping plate 11, then place the rotor on the support frame 2. Because the support frame 2 is V-shaped, it is suitable for rotors of different outer diameters. Then, insert the clamping plate 11 into the corresponding sliding channel 10 (refer to...). Figure 3 As shown, the control moving block 7 slides downward inside the slide frame 4, driving the clamping plate 11 to move downward synchronously. With the cooperation of the support frame 2, the permanent magnet motor rotor is pressed and fixed from top to bottom, making the operation convenient.

[0029] Furthermore, a pin or other structure can be installed between the movable block 7 and the clamping plate 11 to fix the adjusted clamping plate 11, which can be adjusted according to the specific usage.

[0030] In addition, since the slide frame 4 can slide inside the moving groove 3, when the operator controls the slide frame 4 to slide inside the moving groove 3, the clamping plate 11 can move along the axial direction of the rotor, adjust the contact position between the clamping plate 11 and the rotor, facilitate the maintenance of the rotor and other operations, and increase the flexibility of the permanent magnet motor rotor installation tool.

[0031] An electric push rod 12 is installed inside the slide frame 4. The fixed end of the electric push rod 12 is fixedly connected to the bottom of the slide frame 4, and the moving block 7 is fixedly connected to the telescopic end of the electric push rod 12. When the telescopic end of the electric push rod 12 extends, it drives the moving block 7 to slide upward inside the slide frame 4; when the telescopic end of the electric push rod 12 retracts, it drives the moving block 7 to slide downward inside the slide frame 4.

[0032] To improve the stability of the sliding frame 4, a first sliding groove 5 is provided at both the upper and lower ends of the moving groove 3. A first slider 6 is slidably arranged inside the first sliding groove 5. The first slider 6 is fixedly connected to the sliding frame 4. When the sliding frame 4 slides inside the moving groove 3, it will drive the first slider 6 to slide synchronously.

[0033] To prevent the slide frame 4 and other structures from sliding randomly during the rotor fixing process and to improve the stability of the permanent magnet motor rotor installation tool, an elastic telescopic rod 13 is fixedly connected to the bottom of the moving block 7. The bottom of the slide frame 4 is provided with a through hole 14 for the elastic telescopic rod 13 to pass through, and the through hole 14 passes through the first slider 6 located at the bottom end.

[0034] In practical use, the telescopic end of the control electric push rod 12 is retracted, causing the moving block 7 to slide downward inside the slide frame 4. The clamping plate 11 moves downward synchronously, and with the cooperation of the support frame 2, the permanent magnet motor rotor is pressed and fixed from top to bottom. At the same time, the bottom end of the elastic telescopic rod 13 abuts against the inner wall of the first slide groove 5 located at the bottom end. As the moving block 7 slides downward inside the slide frame 4, the elastic telescopic rod 13 retracts. Due to its own restoring elastic force, the bottom end of the elastic telescopic rod 13 is tightly pressed against the inner wall of the first slide groove 5, preventing the slide frame 4 and other structures from sliding arbitrarily.

[0035] After installation, when the telescopic end of the electric push rod 12 extends, it drives the moving block 7 to slide upward inside the slide frame 4, and the elastic telescopic rod 13 extends. The bottom end of the elastic telescopic rod 13 does not contact the inner wall of the first slide groove 5 located at the bottom end, so as not to affect the movement of the slide frame 4 and other structures.

[0036] This utility model uses a structure including a support frame 2, a sliding frame 4, an elastic telescopic rod 13, and a pressing assembly to press and fix the permanent magnet motor rotor from top to bottom, making operation convenient. At the same time, the clamping plate 11 can move along the rotor's axial direction, adjusting the contact position between the clamping plate 11 and the rotor, which facilitates maintenance and other operations on the rotor, increasing the flexibility of the permanent magnet motor rotor installation tool and preventing the sliding frame 4 and other structures from sliding arbitrarily, thus improving the efficiency of the permanent magnet motor rotor installation tool.

[0037] Furthermore, anti-slip textures can be provided on the inner wall of the first groove 5 located at the bottom to improve friction, and this can be adjusted according to specific usage conditions.

[0038] To improve the stability of the moving block 7, a second sliding groove 8 is provided on both inner walls of the sliding frame 4. A second slider 9 is slidably disposed inside the second sliding groove 8 and is fixedly connected to the moving block 7. When the moving block 7 slides inside the sliding frame 4, it drives the second slider 9 to slide inside the second sliding groove 8.
