The column 4 is provided with a jaw device 5 for fixing the reinforcing ring 2, and the column 4 can be uniformly distributed along the circumferential direction of the base 3 in order to enable the jaw device 5 to uniformly fix the annular reinforcing ring 2. Similarly, the synchronous lifting devices 6 for supporting the rotor 1 to synchronously ascend or descend can also be uniformly distributed along the circumferential direction of the base 3, so that the stress balance of the rotor 1 in the assembling and separating processes can be ensured, and the inclination of the rotor 1 can be avoided.

The structure, size, shape and the like of the base 3, the upright post 4, the jaw device 5 and the synchronous lifting device 6 can be determined according to actual conditions and actual requirements in the actual application process.

It should be further noted that the vertical column 4 and the base 3 are vertically and fixedly connected to ensure that the rotor 1 is in a horizontal state and the gap between the stator and the rotor 1 is kept stable during the separation or assembly process of the rotor 1, so as to prevent the stator and the rotor 1 from being adsorbed to each other and affecting the operation effect.

The device is provided with a column 4 for limiting the moving direction of the jaw device 5, namely the moving direction of the rotor 1. In addition, the device utilizes the synchronous lifting device 6 to provide power for the separation and assembly operation of the rotor 1 so as to ensure that all parts of the rotor 1 can synchronously ascend or descend, thus effectively ensuring the separation and assembly quality of the stator and the rotor of the motor.

Finally, the synchronous lifting device 6 is used for providing power for the operation of assembling the rotor 1, namely, the synchronous lifting device 6 can move downwards, so that the rotor 1 supported by the synchronous lifting device 6 can synchronously descend. In addition, the traveling crane can be connected with a hanging hole of the rotor 1, and the rotor 1 is suspended by the traveling crane so as to control the rotor 1 to fall downwards at a uniform speed. Meanwhile, the jaw device 5 and the reinforcing ring 2 synchronously move downwards, so that the levelness of the descending process of the rotor 1 can be always ensured, and finally, the accurate assembly of the rotor 1 and the stator can be ensured.

The motor stator and rotor assembling and separating device provided by the invention is provided with the jaw device 5 and the synchronous lifting device 6, and the jaw device and the synchronous lifting device are matched, so that the levelness of the rotor 1 in the separating and assembling process can be effectively ensured, and the quality of the motor stator and rotor separating and assembling can be effectively ensured. That is, the device can ensure that the reinforcing ring 2 and the rotor 1 are always in a horizontal state in the ascending and descending processes, and can synchronously ascend and descend to avoid the inclination phenomenon of the rotor 1. Since if the rotor 1 is inclined, the rotor 1 and the stator are attracted to each other, so that the assembling and separating operations of the rotor 1 are affected.

On the basis of the motor stator and rotor assembling and separating device, preferably, the base 3 comprises a circular bottom plate 7, a supporting cylinder 8 arranged at the center of the bottom plate 7 and used for supporting the motor, and a cross beam 9 arranged between the end part of the bottom plate 7 and the supporting cylinder 8, the cross beam 9 is uniformly distributed along the radial direction of the bottom plate 7, the upright columns 4 are arranged at the end parts of the cross beams 9, and the synchronous lifting device 6 is arranged in the middle of the adjacent upright columns 4 and is positioned at the end part of the bottom plate 7 so as to ensure that all parts of the rotor 1 are uniformly stressed in the lifting.

Therefore, put into a support section of thick bamboo 8 with the stator of motor, then utilize synchronous elevating gear 6 to support rotor 1 to utilize jack catch device 5 joint that sets up on stand 4 to fix the beaded finish 2 of rotor 1, when making synchronous elevating gear 6 rise or descend, each part atress of rotor 1 is balanced, and the clearance between the stator remains stable, and go up or descend in step, in order to avoid taking place the phenomenon that rotor 1 and stator adsorb each other, thereby can effectively guarantee the operating mass who rotor 1 assembles or separates.

The material, size, structure and the like of the bottom plate 7, the supporting cylinder 8 and the cross beam 9 can be determined according to the actual motor condition and the actual requirement in the actual application process so as to ensure the stress balance of the rotor 1 in the lifting process.

It should be noted that, when assembling the stator and the rotor of the motor, it is necessary to place the end cover plate of the rotor on the supporting disk 10 first, and then place the rotor on the end cover plate. Similarly, when the motor stator and the rotor are separated, the end cover plate needs to be placed on the supporting disk 10, then the end cover plate and the rotor 1 need to be detached, and then the rotor 1 and the stator need to be separated. Therefore, the supporting disk 10 can effectively fix the end cover plate, the levelness of the end cover plate is ensured, and the fixed height of the end cover plate can be effectively adjusted by adjusting the height of the supporting disk 10. The fixed height before the separation of the rotor 1 and the stator can be adjusted, and the fixed height after the assembly of the rotor 1 and the stator can also be adjusted, so that the height requirements of different rotors 1 and stators in the actual application process are met, and the applicability of the device is improved.

It should be noted that the height of the supporting disk 10 can be adjusted, which means that the supporting disk 10 is vertically connected to the cross beam 9 of the base 3 through a bolt, and then the height difference between the supporting disk 10 and the cross beam 9 can be changed through adjusting the bolt, so as to adjust the height of the supporting disk 10, and finally the fixed height of the end cover plate can be adjusted.

The shape, specific position, size and the like of the support disc 10 can be determined according to actual conditions and actual requirements in the actual application process.

On the basis of the motor stator and rotor assembling and separating device, preferably, the synchronous lifting device 6 comprises a jack 11 for axially lifting or lowering the rotor 1 and a hydraulic station for providing power for lifting movement of the jack 11, the jack 11 is connected with the hydraulic station, the hydraulic station is arranged at the center of the base 3, and the jack 11 is arranged between the adjacent upright columns 4 and is positioned at the end part of the bottom plate 7.

It should be noted that the synchronous lifting device 6 is a hydraulic synchronous lifting mechanism, which is mainly used for providing power for the assembling or separating operation of the rotor 1. Wherein, jack 11 can drive rotor 1 and carry out elevating movement under the drive effect at hydraulic pressure station to realize the synchronous lifting or the synchronous decline of rotor, can effectively guarantee the levelness among rotor 1 assembly or the separation process, thereby make the clearance value between rotor 1 and the stator stable, and can not take place the slope adsorption phenomenon, can guarantee the operating mass of rotor 1 and stator finally, avoid taking place to strain the phenomenon of rotor 1.

The device provides power for the assembling or separating operation of the rotor 1 by using the hydraulic synchronous lifting mechanism, breaks through the traditional assembling or separating mode of the stator and the rotor 1, not only saves the manufacturing cost of the device, but also reduces the strain risk of the stator and the rotor 1 in the assembling or separating process to a greater extent, and has simple and convenient use process and strong universality.

In addition, the device can ensure the lifting uniformity of the rotor 1 in the assembling and separating processes, the power of the lifting motion of the rotor 1 is reliable, and the uniformity of air gaps between the stator and the rotor 1 in the assembling and separating processes can be ensured. The device effectively ensures the levelness of the rotor 1 in the assembling or separating process, and increases the safety of the operation process and the reliability of the operation process.

Preferably, six cross beams 9 can be uniformly arranged on the bottom plate 7, and the included angle between the connected cross beams 9 is 60 degrees, so that the stand columns 4 arranged on the cross beams 9 are uniformly distributed, that is, the jaw devices 5 can be uniformly clamped and fixed with the reinforcing ring 2, and the stress balance between the reinforcing ring 2 and the rotor 1 is ensured. In addition, six jacks 11 can be uniformly arranged along the circumferential direction of the bottom plate 7, and the jacks 11 are positioned in the middle of the adjacent upright columns 4, so that the supporting force applied to each part of the rotor 1 is the same, and the reinforcing ring 2 and the rotor 1 can be stably and synchronously lifted.

Of course, three jacks 11 may be uniformly arranged on the base 3, but it is necessary to ensure the force balance of the rotor 1. Therefore, the parameters such as the number and the position of the jacks 11 need to be matched with the specific parameters of the cross beam 9 and the upright post 4 so as to ensure that the rotor 1 keeps horizontal synchronous lifting in the assembling and separating processes.

In the actual application process, parameters such as the number, the structure, the size, the model and the like of the jack 11 and the hydraulic station can be determined according to actual conditions and actual requirements.

On the basis of the above-mentioned assembling and separating device for the stator and the rotor of the motor, preferably, the jaw device 5 includes a supporting member 51 for connecting with the upright column 4, an end supporting plate 52 for supporting the end of the reinforcing ring 2, a bolt 53 for cooperating and clamping with the end supporting plate 52 to axially fix the end of the reinforcing ring 2, and a handle 54 connected with the bolt 53 for controlling the bolt 53 to move telescopically, wherein the supporting member 51 is disposed on the upright column 4, and the end supporting plate 52, the bolt 53 and the handle 54 are disposed on the supporting member 51.

In this embodiment, the end supporting plate 52 is matched with the bolt 53 to clamp the end of the reinforcement ring 2 axially, which may mean that the end supporting plate 52 and the bolt 53 are both disposed on the supporting member 51 and form a groove matched with the size of the end of the reinforcement ring 2 and capable of effectively clamping the end of the reinforcement ring 2. In addition, the handle 54 is used for controlling the bolt 53 to move telescopically, which may mean that the handle 54 and the bolt 53 are connected and fixed through the connecting plate 58, and the handle 54 can be horizontally stretched along the radial direction, so as to drive the bolt 53 to move horizontally telescopically along the radial direction.

Preferably, the handle 54 and the latch 53 are detachably disposed on the supporting member 51, that is, the handle 54 can be horizontally extended in the radial direction to pull out the latch 53, so as to further facilitate the subsequent operation of lifting away the separated rotor 1, and if the latch 53 is fixed on the supporting member 51 all the time, the reinforcing ring cannot be separated from the jaw device 5, which is not beneficial to the subsequent operation of the separated rotor.

It should be noted that if the jaw device 5 is required to be fixedly connected to the reinforcement ring 2, the handle 54 may be pulled in a direction away from the center of the base 3 to drive the latch 53 to retract toward the inside of the supporting member 51, so as to make the end supporting plate 52 fixedly contact with the end of the reinforcement ring 2. Then, the handle 54 is pushed toward the center of the base 3, so that the bolt 53 is pushed to extend from the inside of the support 51, thereby engaging with the end support plate 52 to fix the end of the reinforcement ring 2. Similarly, the connection of the jaw means 5 to the reinforcement ring 2 is accessible by similar operations as described above.

The structure, size, shape, etc. of the support member 51, the end support plate 52, the latch 53, and the handle 54 may be determined according to actual conditions and actual requirements during actual use to ensure that the jaw assembly 5 can effectively fix the reinforcement ring 2.

On the basis of the above-described motor stator and rotor assembly and separation device, the jaw device 5 is preferably provided with hydraulic jacks 55 for abutting against the outer wall surface of the reinforcement ring 2 to radially fix the reinforcement ring 2.

It should be noted that the hydraulic jack 55 is provided inside the jaw device 5 for cooperating with the end support plate 52 and the plug 53, and further radially fixing the reinforcing ring 2 to prevent the reinforcing ring 2 and the rotor 1 from shifting or tilting during the lifting process. That is, the jaw device 5 can limit the local offset of the reinforcement ring 2 and the rotor 1 in the vertical direction through the end support plate 52 and the bolt 53, and can also limit the degree of freedom of the reinforcement ring 2 and the rotor 1 in the horizontal direction through the hydraulic jack 55, and finally, the levelness of the reinforcement ring 2 and the rotor 1 can be effectively ensured.

Therefore, can be at rotor 1's assembly or separation in-process, contact the outer wall of hydraulic jack 55 and beaded finish 2 tip for hydraulic jack 55 can support the tip of beaded finish 2, thereby the effectual phenomenon of guaranteeing that beaded finish 2 does not take place radial movement, can guarantee that rotor 1 is stable in the clearance of lift in-process and stator, and the two can not take place the adsorption phenomenon, also can guarantee that rotor 1 is not impaired not warp.

The position, structure, size, number, etc. of the hydraulic jack 55 can be determined in the actual operation process according to the actual situation and the actual requirements.

For example, four rollers 56 may be provided on the support 51, the four rollers 56 being symmetrically arranged along both sides of the upright 4, i.e. two rollers 56 on one side of the upright 4, so that the jaw assembly 5 moves up and down in a balanced manner. Of course, the number, size, structure, etc. of the rollers 56 may also be determined during the actual operation according to the actual situation and the actual requirements.

On the basis of the above-mentioned assembling and separating device for the stator and the rotor of the motor, it is preferable that the upper end of the upright post 4 is provided with a fixing member 12, and the supporting member 51 is provided with a locking hole 57 which is in locking fit with the fixing member 12, so that the jaw device 5 can be fixed when being lifted to the upper end of the upright post 4.

Preferably, the upright 4 may be provided with locking holes 57 at both sides thereof opposite to both sides where the roller 56 is provided, so as to prevent the fixing member 12 from affecting the movement of the roller 56. Therefore, when the jaw device 5 ascends to the upper end of the upright post 4, the jaw device 5 can be clamped and fixed through the clamping hole 57 and the fixing piece 12, so that the jaw device 5 cannot fall freely, and the phenomenon of part damage is avoided.

It should be further explained that, when the motor stator and rotor assembly and separation device provided by the present invention is used, if the separation operation of the rotor 1 and the stator is required, the motor can be placed on the support cylinder 8 at the center of the base 3 of the device, and the end cover plate is placed on the support disc 10; then, the end supporting plate 52 and the bolt 53 are clamped and axially fixed with the reinforcing ring 2 through the control handle 54, and meanwhile, the reinforcing ring 2 can be radially fixed through the hydraulic jack 55, so that the levelness of the reinforcing ring 2 and the rotor 1 is effectively ensured; then, starting a hydraulic station of the hydraulic synchronous lifting mechanism, so that the hydraulic rod and the jack 11 are synchronously lifted to push the reinforcing ring 2 and the rotor 1 to move upwards, and meanwhile, the jaw device 5 also moves upwards along the upright post 4; finally, after the rotor 1 and the stator are completely separated, the clamping hole 57 and the fixing piece 12 can be used for clamping and fixing, so that the jaw device 5, the reinforcing ring 2, the rotor 1 and the like are locked on the upright post 4, and the separation operation of the rotor 1 is completed.

If the subsequent operation of transporting the separated rotor is needed, the handle 54 and the bolt 53 can be pulled out along the horizontal direction through the control handle 54, and then the rotor is hoisted away by the hoisting device for transportation.

In addition, when the motor stator and rotor assembling and separating device provided by the invention is used, if the assembling operation of the rotor 1 and the stator is required, firstly, the end cover plate can be placed on the supporting disc 10, and then the stator of the motor and the like are placed in the supporting cylinder 8; then, the end supporting plate 52 and the bolt 53 can be clamped and axially fixed with the reinforcing ring 2 by the control handle 54, and meanwhile, the reinforcing ring 2 can be radially fixed by the hydraulic jack 55, so that the levelness of the reinforcing ring 2 and the rotor 1 can be effectively ensured; then, the hydraulic synchronous lifting mechanism is started again, and the hydraulic rod and the jack 11 are synchronously descended through the hydraulic station, so that the reinforcing ring 2 and the rotor 1 synchronously move downwards. In the process, the travelling crane can also be connected with the lifting hole of the rotor 1, and then the rotor 1 is lifted at a constant speed by the travelling crane to move downwards. At the same time, the jaw device 5 will also move downwards along the upright 4; finally, after the rotor 1 moves to the end cover plate, the rotor 1 and the stator are fixedly assembled to complete the assembling operation of the rotor 1.

When the rotor 1 and the stator are assembled, it is preferable that the rotor 1 is lowered synchronously by lifting the rotor 1 by a crane.
