[0001] This utility model relates to the field of motor rotor disassembly and assembly technology, specifically to a disassembly and assembly device for motor rotors. Background Technology

[0002] In the field of motor manufacturing and repair, the disassembly and assembly of motor rotors is one of the core processes. As a core component of industrial power systems, motors are widely used in energy, transportation, and machinery manufacturing. The assembly accuracy of the internal rotor and stator directly affects the motor's operating efficiency and service life. However, traditional disassembly and assembly methods mostly rely on manual operation or simple tools.

[0003] Furthermore, in most civilian recycling operations of small and medium-sized motors, the motor rotor is mostly disassembled manually. However, if the motor rotor cannot be disassembled in one go, the magnets in the motor rotor and stator are easily attracted and rebound, which can damage the coils. Once the coils are damaged, the entire motor can easily be scrapped. Therefore, a disassembly and assembly device for motor rotors is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a disassembly and assembly device for an electric motor rotor to solve the problems mentioned in the background art.

Extension rods are sleeved on both ends of the central output shaft of the motor rotor, and the extension rods are fixed inside the screw fasteners.

[0007] As a further preferred embodiment of this technical solution: the ejection structure includes a rear slide, which is fixedly connected to the other side of the support seat. A slide is slidably connected to the rear slide, and multiple lifting support rods are installed on the slide. A support platform is fixedly connected to the top of the telescopic rod of the lifting support rod. A reciprocating motor is fixedly connected to the support platform, and an impact plate is installed at the end of the reciprocating shaft of the reciprocating motor. Multiple second support electric push rods are installed on the slide of the rear slide, and the piston rod end of the second support electric push rod is movably connected to the bottom of the support platform.

[0008] As a further preferred embodiment of this technical solution: measuring rods are installed on both the support platform and the slide of the front slide, and infrared positioners are installed on opposite sides of the two measuring rods.

[0009] As a further preferred embodiment of this technical solution: a backstop seat is hinged to one side of the rear slide, the bottom of the backstop seat is in contact with the ground, and an electromagnet is installed at the bottom of the support platform, the electromagnet being parallel to the position of the backstop seat.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] Please see Figures 1-4 This utility model provides a technical solution: a disassembly and assembly device for a motor rotor, comprising: a support base 1, a bottom rubber plate 8 fixedly connected to the support base 1, a drive structure installed inside the support base 1, two L-shaped clamps 3 slidably connected to the bottom rubber plate 8, the two L-shaped clamps 3 being connected to the drive structure, a pressing cylinder 4 fixedly connected to the L-shaped clamps 3, a pressing plate 5 installed at the piston rod end of the pressing cylinder 4, side pressing rubber plates 7 fixedly connected to adjacent sides of the two L-shaped clamps 3, a pressing rubber plate 6 fixedly connected to the bottom of the pressing plate 5, a motor rotor placed between the two L-shaped clamps 3, a support structure connected to one side of the support base 1, and a push-out structure connected to the other side of the support base 1.

[0022] In this embodiment, specifically: during use, the operator can disassemble the motor by removing the outer casings at both ends, place the motor casing with the rotor onto the support base 1, and then connect extension rods to both ends of the output shaft of the motor rotor. After the extension rods are connected, one end of the extension rod is connected to the support structure. The drive structure is activated to drive the two L-shaped clamps 3 to squeeze and limit the motor. After the squeezing and limiting is completed, the push structure is activated to quickly push the motor rotor out.

[0023] like Figures 1-4 As shown, the drive structure includes two drive motors 2 fixedly connected to the outside of the support base 1. The output shaft of the drive motor 2 passes through the outer wall of the support base 1 and is fixedly connected to a bidirectional screw 21. Two sliding grooves 23 are opened on the outside of both the support base 1 and the bottom rubber plate 8. Two sliding seats 22 are threadedly connected to the outside of the two bidirectional screws 21 respectively. The four sliding seats 22 are divided into two groups, and the two groups of sliding seats 22 are fixedly connected to the bottom of the two L-shaped clamps 3 respectively.

[0024] In this embodiment, specifically: in the drive structure, by starting two drive motors 2, the bidirectional screw 21 is driven to rotate. When the bidirectional screw 21 rotates, it will drive the two sliding seats 22 located outside the bidirectional screw 21 to move. When the two sliding seats 22 move, the two L-shaped clamps 3 will move closer to each other. When the two L-shaped clamps 3 move closer to each other, the motors located on the bearing seat 1 and the bottom rubber plate 8 can be fixed and limited.

[0025] like Figure 4 As shown, the lower pressure rubber plate 6, the side pressure rubber plate 7 and the bottom rubber plate 8 are all provided with hollow cavities, and the interior of the hollow cavities is filled with electrorheological fluid 24.

[0026] In this embodiment, specifically: when further limiting the motor is required, the lowering cylinder 4 can be activated to drive the lowering plate 5 to further fix and limit the motor housing. After the motor housing is fixed and limited, the L-shaped clamping plate 3 will drive the side pressure rubber plate 7, and the lowering plate 5 will drive the lowering rubber plate 6 to be squeezed to the outside of the motor. At this time, the bottom rubber plate 8, the side pressure rubber plate 7, and the lowering rubber plate 6 will all deform due to the compression with the motor. Under the condition of forming the corresponding deformation, the electrorheological fluid 24 located inside the bottom rubber plate 8, the side pressure rubber plate 7, and the lowering rubber plate 6 is energized again through the external wire, so that the electrorheological fluid 24 hardens. Under the condition of hardening, a snap-fit ​​groove matching the shape of the motor housing can be formed. Under the condition of forming a matching snap-fit ​​groove, the connection stability of the motor can be further increased.

[0027] like Figure 1As shown, the support structure includes a front slide 9, which is fixedly connected to one side of the bearing seat 1. A slide is slidably connected on the front slide 9, and a first support electric push rod 10 is installed on the slide. A screw fastener 11 is installed at the piston rod end of the first support electric push rod 10. Both ends of the motor rotor center output shaft are fitted with extension rods, which are fixed inside the screw fastener 11.

[0028] In this embodiment, specifically: in the support structure, the extension rod is connected to the inside of the screw fastener 11, and the extension rod is squeezed and limited by the external screw extrusion member of the screw fastener 11, thereby limiting the extension rod. In addition, during the connection process, the front slide 9 can be activated to drive the slide, the first support electric push rod 10 on the slide, and the screw fastener 11 to move to the appropriate position of the motor extension rod to form a corresponding support. At the same time, the screw fastener 11 can be moved up and down by activating the first support electric push rod 10 to adapt to the position changes of different motor central shafts.

[0029] like Figures 1-3 As shown, the ejection structure includes a rear slide 12, which is fixedly connected to the other side of the support base 1. A slide is slidably connected on the rear slide 12. Multiple lifting support rods 13 are installed on the slide of the rear slide 12. A support platform 14 is fixedly connected to the top of the telescopic rod of the lifting support rod 13. A reciprocating motor 15 is fixedly connected to the support platform 14. An impact plate 16 is installed at the end of the reciprocating shaft of the reciprocating motor 15. Multiple second support electric push rods 25 are installed on the slide of the rear slide 12. The piston rod end of the second support electric push rod 25 is movably connected to the bottom of the support platform 14.

[0030] In this embodiment, specifically: when the motor rotor is ejected, the second support electric push rod 25 is activated to drive the support platform 14 to move up and down, and the lifting support rod 13 assists in raising and lowering the height of the support platform 14. During the height raising and lowering process, the position height of different motor center shafts is matched. After moving to the matching height position, the reciprocating motor 15 is activated to perform rapid reciprocating motion. During rapid reciprocating motion, the rear side slide 12 is activated to drive the support platform 14 and the reciprocating motor 15 to move rapidly to the position of the extension rod of the motor rotor. The reciprocating motor 15 quickly ejects the impact plate 16, and the impact plate 16 collidees with the extension rod at high speed concentrically, thereby quickly separating the motor rotor from the outer casing.

[0031] like Figure 1 As shown, measuring rods 17 are installed on both the support platform 14 and the front slide 9. Infrared positioners 18 are installed on opposite sides of the two measuring rods 17. The concentricity of the lifting height of the support platform 14 can be calculated by the measuring rods 17 and the infrared positioners 18 on the two slides, so as to ensure the accuracy of the concentricity.

[0032] like Figures 2-3 As shown, a backstop seat 19 is hinged to one side of the rear slide 12. The bottom of the backstop seat 19 is in contact with the ground. An electromagnet 20 is installed at the bottom of the support platform 14. The electromagnet 20 is parallel to the position of the backstop seat 19.

[0033] In this embodiment, specifically: multiple infrared positioners 18 are installed on the outside of the measuring rod 17 located on the front slide 9, which are used to measure the concentricity with the motor rotor. The measuring rod 17 can also be set to a lifting state for better measurement.

[0034] In this embodiment, specifically: when the reciprocating motor 15 on the support platform 14 drives the impact plate 16 to impact the extended rod of the motor rotor, the hinged anti-reverse seat 19 can contact the ground, thereby providing anti-reverse force to the slide of the rear slide 12, preventing the impact force from being fed back to the slide of the rear slide 12 and causing the phenomenon of sliding in the opposite direction. At the same time, when the anti-reverse seat 19 is not needed, it is only necessary to activate the electromagnet 20 to attract the anti-reverse seat 19, thereby causing the anti-reverse seat 19 to separate from the ground, thus no longer providing anti-reverse effect.

[0035] Working principle: During use, the staff first removes the outer casings at both ends of the motor to be disassembled, places the motor casing with rotor on the bearing seat 1, and connects extension rods to both ends of the motor rotor output shaft, connecting one end of the extension rod to the support structure;

[0036] The drive structure is activated, specifically by driving motor 2 to rotate bidirectional screw 21, causing sliding seat 22 to move, which in turn causes two L-shaped clamps 3 to move closer to each other, fixing and limiting the motor on bearing seat 1 and bottom rubber plate 8.

[0037] If further limiting is required, the lowering cylinder 4 is activated to drive the lowering plate 5 to fix the motor housing. At this time, the L-shaped clamp 3 drives the side pressing rubber plate 7 and the lowering plate 5 drives the lowering rubber plate 6 to squeeze the outside of the motor and generate deformation. Then, the electrorheological fluid 24 inside the bottom rubber plate 8, the side pressing rubber plate 7 and the lowering rubber plate 6 is energized to harden it, forming a snap-fit ​​groove that matches the shape of the motor housing, enhancing the connection stability. In the support structure, the extension rod is connected to the screw fastener 11. The screw fastener 11 is used to squeeze and limit the extension rod. At the same time, the front slide 9 is activated to drive the slide, the first support electric push rod 10 and the screw fastener 11 to move to the appropriate position of the motor extension rod. The screw fastener 11 can also be moved up and down by activating the first support electric push rod 10 to adapt to the position changes of the central shaft of different motors.

[0038] When the motor rotor is ejected, the second support electric push rod 25 is activated to drive the support platform 14 to move up and down. The lifting support rod 13 assists in raising and lowering the height of the support platform 14 to match the position height of different motor center shafts. After moving to the matching height position, the reciprocating motor 15 is activated to perform rapid reciprocating motion. At the same time, the rear slide 12 is activated to drive the support platform 14 and the reciprocating motor 15 to move quickly to the position of the extended rod of the motor rotor. The reciprocating motor 15 quickly ejects the impact plate 16, causing the impact plate 16 to collide with the extended rod at high speed concentrically, thus quickly separating the motor rotor from the outer casing.
