As shown in fig. 1, the support plate body 21 has a first through hole 21a at the geometric center, and the direction of the first through hole 21a is the same as the thickness direction of the support plate body 21. The shape of the first through hole 21a may be circular or rectangular, and when the center pillar 31 is cylindrical, the shape of the first through hole 21a is circular, and when the center pillar 31 is hexagonal, the shape of the first through hole 21a is rectangular.
Claw body 22
The claw body 22 is a member in the support plate 2 for connecting the support plate body 21 and the support leg 1.
As shown in fig. 1, the claw body 22 has a bar-shaped structure, a plurality of claw bodies 22 are located at the side of the support plate body 21, and both ends of each claw body 22 are connected to the support plate body 21 and the support leg 1, respectively.

The screw hole 22a is used for matching with the second through hole 1c of the supporting leg 1, so that the claw body 22 is detachably connected with the supporting leg 1. Thus, the processing difficulty of the motor stator dismounting device can be reduced.
As an example, the internal thread of the threaded hole 22a may be a fine thread or a round thread.
In this way, stress concentration at the root of the tooth can be reduced, and the installation stress generated by the bolt in the installed state can be reduced. Also, since the claw body 22 is connected with the support leg 1, the support leg 1 needs to support the stator, and the stator may rotate around the axis of the center post 31 at the support leg 1. In the process of rotating the stator, the supporting leg 1 loads the claw body 22, the internal thread of the threaded hole 22a is set to be a fine thread or a round thread, the bolt can be guaranteed to have good self-locking performance under the action of the load, and the bolt is prevented from falling off during operation.
Alternatively, the support plate 2 may be an integrally formed part, i.e., the support plate body 21 and the claw body 22 are integrally formed.
Alternatively, the support plate 2 may be formed in steps, that is, the support plate body 21 and the claw body 22 are formed separately and then coupled together by bolts. When the support plate body 21 and the jaw body 22 are respectively formed, the screw hole 22a located at the jaw body 22 may be a screw through hole, and the support plate body 21 and the jaw body 22 have support plate body screw holes having the same aperture as the screw hole 22 a. In this way, the support leg 1, the claw body 22 and the support plate body 21 can be detachably connected by the bolts sequentially passing through the support leg 1, the claw body 22 and the support plate body 21.
The processing method of the support plate 2 may be casting processing, cutting processing, or pressing processing, and the embodiment of the present application is not limited thereto.
The material of the support plate 2 may be a metal material with good mechanical properties, such as nickel-iron alloy, aluminum-magnesium alloy, and the like, which is not limited in the embodiment of the present application.
In the motor stator attaching/detaching device, a plurality of support plates 2 may be provided in the motor stator attaching/detaching device. The more the number of the support plates 2 is, the greater the overall strength of the motor stator dismounting device is, and a technician can set the number of the support plates 2 according to actual needs. For example, when the mover is made of a metal material having a relatively high density, the number of support plates 2 in the motor stator assembling/disassembling device can be increased, and when the mover is made of a metal material having a relatively low density, the number of support plates 2 in the motor stator assembling/disassembling device can be reduced.
As shown in fig. 1, the motor stator assembling and disassembling device has two support plates 2, and the two support plates 2 are parallel to each other.
3. Intermediate limiting mechanism 3
And the middle limiting mechanism 3 is used for limiting a component of the motor rotor in the motor stator dismounting device. As shown in fig. 1, the intermediate stopper mechanism 3 includes a center post 31 and a stopper disk 32.
Center post 31
As shown in fig. 1, the center post 31 is located in the first through hole 21a of the support plate body 21 and is connected to the support plate body 21.
The center post 31 has a cylindrical structure, and the center post 31 includes a first portion, a second portion, and a third portion having external threads 31a.
The first portion, the second portion and the third portion are coaxially connected, the second portion is located between the first portion and the third portion, diameters of the first portion, the second portion and the third portion are d1, d2 and d3 respectively, d2> d1=d3, and the diameter of the first portion is the same as the diameter of the first through hole 21 a.
In this way, the center pillar 31 can be ensured to have high strength.
Spacing disc 32
The limiting disc 32 is a part of the intermediate limiting mechanism 3 for connecting with the inner wall of the engine stator to limit the engine stator.
As shown in fig. 1, the limit disk 32 has a cylindrical structure, and the edge is rounded, the geometric center of the limit disk 32 has an internal thread through hole 32a, and the limit disk 32 is connected with the center column 31 through the cooperation of the internal thread through hole 32a and the external thread 31 a.
In this way, the limit disk 32 can be moved up and down on the axis of the center post 31 extending the center post 31 by the cooperation of the female screw through hole 32a and the male screw 31 a.
As an example, the internal thread of the internal thread through hole 32a may be a fine thread or a round thread.
In this way, stress concentration at the root of the tooth can be reduced, and the installation stress generated by the bolt in the installed state can be reduced. And, since the limit disk 32 is in contact with the inner wall of the motor stator, the mass of the motor stator is large, and the stator may be rotated about the axis of the center post 31 when disassembled. In the process of rotating the stator, load exists on the limiting disc 32 by the inner wall of the stator, the internal thread of the internal thread through hole 32a is set to be a fine thread or a round thread, and the bolt can be guaranteed to have good self-locking performance under the action of the load, and the position of the internal thread through hole 32a is changed.
The engine stator generally has a hollow cylindrical structure, and the outer diameter of the limit disk 32 may be set to the same size as the inner diameter of the stator.
Thus, when the engine stator is placed on the first step structure 1a, the position of the limit disc 32 on the center post 31 can be adjusted up and down, so that one surface of the limit disc 32 away from the support plate 2 contacts with the top surface of the stator, and the outer wall of the limit disc 32 contacts with the inner wall of the stator, thereby limiting the stator.
The motor stator dismounting device can further comprise a base 4, as shown in fig. 1, the base 4 is provided with a circular ring-shaped structure, and the base 4 is detachably connected with the bottom ends of the supporting legs 1 through bolts.
Alternatively, as shown in fig. 2, the outer circumferential surface of the base 4 has a positioning groove 4a thereon, and the positioning groove 4a is adapted to cooperate with a positioning projection of the table to restrict the rotational movement of the base 4. The surface of the positioning groove 4a, which is in contact with the positioning projection, is an arc surface, so that the stress concentration of the positioning groove 4a can be reduced.
Alternatively, as shown in fig. 2, the surface of the base 4 away from the bottom end of the supporting leg 1 has an annular protrusion 4b, and the annular protrusion 4b is used to cooperate with a circular through hole of the workbench to limit the translation of the base 4.
Like this, connect supporting leg 1 on the one side that base 4 is close to supporting leg 1 to set up constant head tank 4a and annular protruding 4b on base 4, prevent base 4 to take place rotary motion and translational motion in the workstation, can guarantee at the in-process of dismouting motor stator, motor stator dismouting device remains stable throughout.
Optionally, the base 4 may further have a plurality of bolt stop holes for fixedly connecting the base 4 with the table.
The motor typically includes a coil, which is typically wound around the stator, a stator, and a housing, which is secured to an outer wall of the stator by a plurality of bolts. When overhauling, need dismantle the motor, dismantle the shell on the stator outer wall, and then be convenient for inspect whether the structure of stator breaks down, accomplish after overhauling, need install the shell again on the outer wall of stator. Next, the process of assembling and disassembling the motor stator is briefly described:

And thirdly, screwing out bolts for connecting the stator and the shell, vertically suspending the shell by using a lifting appliance, sliding and separating the stator from the shell under the action of gravity of the stator, taking down the shell and placing a designated position, and thus completing the disassembly of the motor stator.
Finally, the limit disc 32 is downwards adjusted, so that the outer wall of the limit disc 32 is not contacted with the inner wall of the stator, the limit of the motor is relieved, and the disassembled stator is taken down.
(2) Installation process of motor stator
First, the assembled motor stator assembling and disassembling device is mounted on a workbench, and whether the motor stator assembling and disassembling device cannot perform translational motion and rotational motion is checked.
Secondly, after determining whether the motor stator dismounting device cannot perform translational motion and rotational motion, lifting the stator by using a lifting appliance and placing the stator in the first step structure 1a, and adjusting the limiting disc 32 upwards to enable the outer wall of the limiting disc 32 to be in contact with the inner wall of the stator, so that the limiting of the stator is completed.
And placing the guide rods in the stator threaded holes of the stator, lifting the shell by using a lifting appliance, enabling the guide rods to pass through the shell threaded holes corresponding to the stator in the shell, then taking out the guide rods one by one, and installing a bolt every time one guide rod is taken out.

Wherein the range of the first angle is 120-150 degrees, and the range of the second angle is 30-60 degrees.
Alternatively, the first angle and the second angle may be complementary.

In this way, the angle between the first jaw 221 and the second jaw 222 is set to the first angle, and the angle between the third jaw 223 and the fourth jaw 224 is set to the second angle, and when the motor is placed on the motor stator attaching/detaching device, if the three-phase line is in a wide-pitch distribution, the three-phase line is placed between the first jaw 221 and the second jaw 222, and if the three-phase line is in a narrow-pitch distribution, the three-phase line is placed between the third jaw 223 and the fourth jaw 224, preventing the three-phase line from coming into contact with the jaw 22 or the support leg 1.
Alternatively, the second jaw 222 and the third jaw 223 may be at a third angle, and the first jaw 221 and the fourth jaw 224 may be at a fourth angle.
Wherein the third angle is equal to the fourth angle.
Thus, the difficulty in manufacturing the support plate 2 can be reduced, and the overall strength of the motor stator attaching/detaching device can be improved.
