One end of the screw is connected to the handle, and the nut has a first internal thread and a second internal thread with different diameters. The first internal thread cooperates with the screw, and the second internal thread cooperates with the external thread on the motor main shaft.

[0004] The above structure is connected to the external thread on the motor shaft through a nut. The motor can be easily removed by turning the handle.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 、 Figure 2 and Figure 3As shown, a tool for disassembling the motor of an electric screw equipment includes a motor end cover 10, and multiple groups of screws 1 are detachably installed on the top of the motor end cover 10. A cross arm 2 is passed through the outside of the screw 1, and a nut 8 is threadedly connected to the top of the screw 1; a pad 3 is fixedly installed at the bottom center of the cross arm 2, and a hydraulic jack 4 is fixedly installed at the bottom end of the pad 3, and a pressure plate 5 is fixedly installed at the output end of the hydraulic jack 4, and multiple groups of support frames 6 are arranged around the bottom of the pressure plate 5, and a ring 7 is fixedly installed at the bottom end of the support frame 6, and the bottom of the ring 7 is in contact with the disc spring pressure cover 11.

[0020] In this embodiment, when the motor needs to be disassembled, the screw 1 is installed on the motor end cover 10, and a crossbeam 2 with a hydraulic jack 4 is installed between adjacent screws 1. The bottom of the hydraulic jack 4 is installed with a pressure plate 5, a support frame 6 and a ring 7 at the bottom of the pressure plate 5, and the bottom of the ring 7 contacts the disc spring pressure cover 11, so that the tooling corresponds to the motor, and the hydraulic jack 4 is used to compress the disc spring pressure cover 11 to compress the disc spring 12 to ensure the pressure balance of the disc spring 12, leaking out the locking nut 14 and the motor shaft screw 13, and then easily loosening the locking nut 14 with a wrench, so that the inside of the motor can be quickly disassembled, thereby improving the efficiency of equipment inspection and maintenance, reducing damage to the threads of the motor shaft screw 13 and the locking nut 14, and extending the service life of the motor.

[0021] As an implementation method, Figure 2 and Figure 3 As shown, the inner diameter of the collar 7 is larger than the outer diameter of the locking nut 14 , and the inner diameter of the collar 7 is smaller than the outer diameter of the disc spring cover 11 .

[0022] In this embodiment, the inner diameter of the collar 7 is larger than the outer diameter of the locking nut 14. After the collar 7 contacts the disc spring cover 11, the collar 7 is outside the locking nut 14 on the disc spring cover 11. When the hydraulic jack 4 is used to compress the disc spring cover 11 and the disc spring 12 is compressed, the locking nut 14 can be easily loosened with a wrench, making it easy to disassemble and assemble.

[0023] As an implementation method, Figure 1 、 Figure 2 and Figure 3 As shown, there are at least three groups of support frames 6, and the pressing plates 5 and the sleeve rings 7 are arranged parallel to each other.

[0024] In this embodiment, the support frame 6 is fixed between the pressure plate 5 and the collar 7. When the hydraulic jack 4 compresses the disc spring cover 11 and the disc spring 12 is compressed, the wrench can loosen the locking nut 14 between adjacent support frames 6.

[0025] As an implementation method, Figure 1 、 Figure 2 As shown, the cross arm 2 and the cushion block 3 are arranged perpendicular to each other, the cushion block 3 is a cylindrical structure, and the cushion block 3 is a rubber component.

[0026] In this embodiment, the spacer 3 is installed on the hydraulic jack 4. When the hydraulic jack 4 is in action, the spacer 3 reduces the force between the hydraulic jack 4 and the cross arm 2.

[0027] As an implementation method, Figure 1 As shown, there are at least two groups of screw rods 1, and the screw rods 1 are arranged in a bilaterally symmetrical manner with respect to the center of the motor end cover 10.

[0028] In this embodiment, the connection between the screw rod 1 and the motor end cover 10 is utilized, the top ends of the two sets of screw rods 1 are connected to the cross arm 2, and the bottom of the cross arm 2 is pressurized by the hydraulic jack 4 to avoid the problem of the nut being affected by the elasticity of the disc spring 12 when being disassembled and assembled.

[0029] As an implementation method, Figure 2 and Figure 3 As shown, the collar 7 and the disc spring cover 11 are arranged correspondingly up and down, and the bottom of the collar 7 is provided with anti-slip grooves.

[0030] In this embodiment, a hydraulic jack 4 is used to compress the pressure plate 5, and a support frame 6 is used to fix the pressure plate 5 and the collar 7. The anti-slip grooves of the collar 7 contact the disc spring cover 11 to increase friction, thereby pressing the disc spring cover 11 and compressing the disc spring 12. After the disc spring 12 is compressed, the locking nut 14 is loosened, which causes less damage to the threads of the motor shaft screw 13 and the locking nut 14.

[0031] Working principle: When in use, when disassembling the motor, install the screw 1 on the motor end cover 10, install the cross arm 2 with the hydraulic jack 4 between the adjacent screws 1, install the pressure plate 5 at the bottom of the hydraulic jack 4, the support frame 6 and the collar 7 at the bottom of the pressure plate 5, the bottom of the collar 7 contacts the disc spring pressure cover 11, make the tooling correspond to the motor, use the hydraulic jack 4 to compress the pressure plate 5, and use the support frame 6 to fix between the pressure plate 5 and the collar 7, thereby pressing the disc spring pressure cover 11, compressing the disc spring 12, and using the pad 3 Installed on the hydraulic jack 4, when the hydraulic jack 4 is in action, the pad 3 is used to reduce the force between the hydraulic jack 4 and the cross arm 2, ensuring the pressure balance of the disc spring 12, leaking out the locking nut 14 and the motor shaft screw 13, and the wrench can loosen the locking nut 14 between adjacent support frames 6 and then easily loosen the locking nut 14 through the wrench, thereby quickly disassembling the inside of the motor, improving the equipment inspection and maintenance efficiency, reducing damage to the motor shaft screw 13 and the locking nut 14 thread, and extending the service life of the motor.
