Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the motor stator disassembling apparatus 100 according to the present invention includes a base 10 fixed to the ground to support the entire structure, and two support actuators having one end coupled to the base 10 ( 20), an operating actuator 30 disposed between the support actuators 20 and having one end fixed to the base 10, a connector 40 coupled to the operating part of the operating actuator 30, the connector ( 40) coupled tongs 50, a hydraulic device 70 for supplying hydraulic pressure to the support actuator 20 and the actuating actuator 30, and a control module for adjusting the hydraulic pressure of the hydraulic device 70 as needed ( 90) is included.

First, the base 10 is a structure installed on the ground, and the bottom part 11 serving as a working floor, two side parts 12 vertically disposed on the left and right sides of the bottom part 11, and the side part 12 are horizontal on the top. It is configured to include an upper end 13 disposed as.

Of course, for the convenience of operation, the bottom part 11 preferably has a flat top surface, but it is preferable that the other parts have a frame structure in consideration of strength and the like.

Since the base 10 provides a working area and serves as a supporting structure for other devices, it is advantageous to have high rigidity.

Meanwhile, as shown in FIG. 2 , a support actuator 20 is connected to the lower surface of the upper end 13 .

The support actuator 20 is a double-acting hydraulic actuator, and includes a second cylinder 21 and a second actuating rod 22, and a contact portion 23 is formed at the end of the second actuating rod 22 to form a rotor. (1) serves to fix the upper end (13) and is composed of two in the same form.

The second cylinder 21 has second hydraulic ports 25 through which hydraulic pressure flows in and out at both ends, respectively.

In addition, a second piston 26 is formed in a portion of the second operating rod 22 located inside the second cylinder 21 , and is applied to the hydraulic pressure supplied and discharged through the second hydraulic port 25 . Accordingly, the second piston 26 moves into the second cylinder 21 , and simultaneously transfers the second actuating rod 22 .

One end of the second cylinder 21 is hinged 27 with the lower surface of the upper end 13 . Accordingly, the support actuator 20 is rotatable about the hinge 27 located on the upper end 13 .

In addition, the contact portion 23 is a portion in contact with the core of the rotor (1), and it is advantageous for fixing the rotor (1) to be configured in an arc shape.

The two support actuators 20 fix the rotor 1 in a form in which the second actuating rod 22 is pressed downward, as shown in FIG. 3 . At this time, the rotor 1 is preferably disposed in the center between the support actuators (20).

On the other hand, as shown in FIG. 4 on the upper surface of the upper end part 13, an operating actuator 30 is installed.

The actuating actuator 30 is also a double-acting hydraulic actuator, and includes a first cylinder 31 and a first actuating rod 32 , and a connection part 33 is formed at an end of the first actuating rod 32 . And the first cylinder 31 has first hydraulic ports 35 through which hydraulic pressure flows in and out at both ends, respectively, and is located inside the first cylinder 31 among the first operating rods 32 . A first piston 36 is formed in the portion, and the first piston 36 moves into the first cylinder 31 according to the action of the hydraulic pressure supplied through the first hydraulic port 35, and at the same time The first actuating rod 32 is also transported.

One surface of the first cylinder 31 is fixed to the upper end 13 , and the first operation rod 32 is disposed downward through a hole formed in the upper end 13 .

And when hydraulic pressure is supplied to the first cylinder 31 , the first operation rod 32 is transferred in the vertical direction.

An annular connecting portion 33 is formed at an end of the first actuating rod 32 .

A chain-shaped connector 40 is coupled to the connecting portion 33 in a closed loop form. That is, the connector 40 is inserted into the annular connection part 33 in a separated state, and then is combined again to form a closed loop.

On the other hand, the motor stator disassembly apparatus 100 according to the present invention includes the tongs 50 as shown in FIG.

The tongs 50 are coupled so that the body portion 51 configured in a symmetrical shape is relatively rotatable through the support point 52 .

The body part 51 is divided into an action part 53 and a pressing part 54, and an annular end part 55 is formed at the end of the pressing part 54.

In addition, the body part 51 is formed with a stopper or the like so that when the pressing part 54 is pressed, the working part 53 rotates and approaches each other, but the rotational motion is stopped at a certain distance. The distance is set in consideration of size and pressing force.

If the pressing parts 54 are in complete contact with each other, there is a disadvantage in that the copper wires located between the pressing parts 54 are completely cut and cannot be withdrawn.

And the chain-shaped connector 40 is inserted into the end portion 55 of the annular shape.

That is, the connector 40 is disposed in a closed loop shape after passing through the annular connector 33 and the two end portions 55 as shown in FIG. 6 .

On the other hand, a method of disassembling the stator 1 using the motor stator disassembling apparatus 100 according to the present invention will be described in detail with reference to FIG. 7 .

First, the stator 1 is disposed at the center of the base 10 and the bottom 11 of the base 10 . Of course, the stator 1 can be arranged outside the central part, but when it is arranged in the central part, it is preferable because workability is the best, and if necessary, the central part of the bottom part 11 can be separately marked and displayed.

Then, the two support actuators 20 are operated so that each contact part 23 presses the left and right sides of the core of the stator 1 . Of course, the stroke of the second actuating rod 22 of the support actuator 20 is driven in a lengthening direction to strongly fix the stator 1 to the bottom 11 . At this time, the operator adjusts the direction so that the contact portion 23 of the support actuator 20 faces the stator 1 core.

After the stator 1 is fixed, the operator adjusts the tongs 50 so that the acting part 53 of the tongs 50 bites the copper wire wound on the stator 1. The tongs 50 are the copper wire In the case of biting, the forceps 50 itself keeps biting the copper wire by its own weight, and the position of the tongs 50 adjusts the stroke of the first operating rod 32 and the length of the connector 40 so that the working part at the end of the copper wire (53) should be located.

Thereafter, when the hydraulic pressure is supplied to the actuating actuator 30 in a direction in which the stroke of the first actuating rod 32 of the actuating actuator 30 is reduced, the clamp 50 is a copper wire by the action of the connector 40 is strongly gripped and transported to the top at the same time to separate the copper wire from the stator (1) core.

Thereafter, the operation is performed on the copper wire wound on the other part in the same manner, and when the separation of the entire copper wire is completed, the hydraulic pressure of the support actuator 20 is removed to complete the entire separation operation.

Here, an operation such as supplying hydraulic pressure is performed by directly manipulating the control module 90 by the operator.
