Description

[0001] DESCRIPTION [0002] Coil drawing apparatus [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for pulling out and separating a coil of a motor, and more particularly, to a motor coil take-out apparatus in which a coil of an electric motor can be easily drawn out.

An electric motor serves to convert electrical energy into rotational energy using the force that a current-carrying conductor receives in a magnetic field.

DC motors and AC motors are classified according to the type of power source. AC motors are divided into three-phase alternating current and single-phase alternating current. Today, three phase AC motors are mainly used.

In particular, the power source used in indoor and small appliances, which are difficult to use internal combustion and external combustion engines, is indispensable in the case of rotational motions.

Typically, fan. Electric motors are used in refrigerators, air conditioners, various machines, and transportation equipment.

1 shows a structure of a general electric motor 100. A stator having a cylindrical coil 120 is fixed to the inside of the housing 110 and a rotor made of a magnet is fixed to the output shaft.

A gap is formed between the outer periphery of the rotor and the inner periphery of the coil 120 as a stator.

Therefore, when a current flows through the coil 120, the rotor rotates by the magnetic field to generate power.

In order to separate the coil 120 from the housing 110, it is necessary to use an enamel for insulating the coil 120. In order to separate the coil 120 from the housing 110, .

That is, since enamel, which is an insulating material, is coated on the outer side of the coil 120 to insulate the coil 120, the coil 120 is separated from the housing 110 by dissolving the enamel by heat.

However, in order to separate the enamel, the coil 120 is separated from the housing 110 in a state where the enamel is burned or melted by heat by manual operation. However, when the enamel is burnt or melted, toxic gas is generated, And the odor of burning the enamel is very poisonous, which is not very good in the surrounding environment.

In addition, after the enamel is separated, the worker must separate the coil 120 from the housing 110 by applying a force.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a motor-take-out apparatus in which a housing is fixed and then only a coil is taken out to solve such a problem.

According to an aspect of the present invention,

A table on which the motor is placed;

A cylinder vertically moving through the table;

A withdrawing arm which is positioned at an upper end of the cylinder rod and is exposed to the upper side of the table, and which is laterally rotated to be caught at a lower side of the coil of the motor;

And a fixing jig for fixing the housing of the motor to the upper surface of the table.

According to the present invention as described above, the coil is separated from the housing by the mechanical operation without separating the coils manually by the operator, so that the operation is easy and the working efficiency is increased. Furthermore, the enamel, It is possible to prevent the generation of the toxic gas and the pollution of the surrounding environment.

1 is a view showing the structure of a general electric motor.
2 is an exploded view of a motor coil drawing apparatus according to the present invention;
3 is a cross-sectional structural view illustrating a process of pulling out a motor coil according to the present invention.

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a view showing a decomposition structure of a motor coil take-off device according to the present invention. A cylinder 220 (see FIG. 2), which is vertically reciprocated by a power generating part 240 such as a motor, The rod of the cylinder 220 reciprocates through the table 210 from the lower side to the upper side.

The lead portion 230 is mounted on the upper end of the rod 220 of the cylinder 220. The lead portion 230 is provided with a shaft 231 connected to the rod of the cylinder 220, Ring body 233 is provided.

The drawer arm 232 is rotatably mounted to the ring body 233 in four directions. When the drawer arm 232 is rotated downward while being fixed to the ring body 233 by a hinge, And when the upper side rotates, the plurality of drawing arms 232 are raised and gathered to each other.

A plurality of fixing holes 211 are formed on the periphery of the lead portion 230 on the upper surface of the table 210. These fixing holes 211 are formed at regular intervals and formed with threads on the inner side.

A fixing jig 250 for fixing the housing of the motor 100 to the upper surface of the table 210 is screwed to the fixing hole 211. The fixing jig 250 is in the shape of " And the protruding upper end pushes the upper surface of the housing of the motor 100 to fix it.

At this time, the height of the motor 100 can be adjusted by controlling the depth of the fixing hole 211 or by adjusting the height of the fixing jig 250 itself.

The motor 100 is placed on the upper surface of the table 210 in a state where the lead portion 230 is received in the middle portion and the space portion 130 between the housing 110 and the coil 120 The housing fixing part 260 is inserted into the housing 110 and the coil 120 in a ring shape and has a flat top surface.

When the housing fixing portion 260 is inserted into the motor 100, the protruding portion of the fixing jig 250 is placed on the flat portion of the upper portion of the housing fixing portion 260, and the motor 100 is stably fixed to the upper surface of the table 210 .

3 is a view for explaining a process of drawing the coil 120 of the motor 100 according to the present invention. When the rod of the cylinder 220 is lowered, the lead- At this time, the drawing arm 232 comes into contact with the coil 120 of the motor 100 and is rotated upward by the hinge portion 234, so that the drawing arm 232 is rotated.

When the drawer 230 is lowered to the lower side of the coil 120, the worker unfolds the drawer arm 232 in the horizontal direction. When the rod of the cylinder 220 is raised, As shown in FIG.

When the rod 220 of the cylinder 220 continuously ascends and is exposed to the upper side of the motor 100, only the coil 120 is caught by the drawing arm 232 while the housing 110 is fixed by the fixing jig 250, 110) and separated.

Thereafter, the housing 110 from which the coil 120 is removed can be removed by separating the fixing jig 250 from the table 210.
