Abstract
Description
The present invention relates to a rotor slot and a stator slot punching apparatus, in which a punch protruding means is provided between a punch holder and a punch fixing plate, so that a punching operation can be performed by selectively protruding a rotor punch and a stator punch during a punching operation of the core The present invention relates to a rotor slot and a stator slot striking device.
2. Description of the Related Art Generally, a motor includes a stator fixedly installed inside a housing of a motor, and a rotor disposed in the stator so as to be spaced apart from the stator and rotated by an interaction between the stator and the stator.
When power is supplied to the stator, an electric force is generated and the rotor is rotated by the interaction with the magnetic force of the magnet provided on the rotor.
The stator includes a stator core formed by stacking a plurality of steel plates in a circular shape, and a coil wound around the stator core. The stator core has a structure in which a hollow plate is formed at the center and a slot is formed in a predetermined number of slots at a predetermined interval around the hollow portion.
Conventionally, a rudder is used to machine the stator core. Such a conventional rudder is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0120105.
The rudder has a press portion driven by a motor and a pedestal for fixing and fixing the stator core to the lower portion of the press.
When the drive shaft and the gear plate of the motor are engaged with each other and the teeth are rotated as much as the teeth, the stator core is rotated in the same manner in conjunction with the gear plate on which the teeth are formed, Thereby forming a slot.
However, in the conventional rudder, the rotor slot and the rudder forming the stator slot are separately formed. When the rotor slot process is completed in the core, the operator moves the stator slot process to the stator slot rasterizer.
Therefore, since the rotor slot process and the stator slot process must be separately performed, a long working time is required and defects may occur due to movement of the core.
SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the problems of the prior art as described above, and it is an object of the present invention to provide a punching device for punching a core by selectively punching a rotor punch and a stator punch And to provide a rotor slot and a stator slot punching device capable of performing a punching operation.
According to an aspect of the present invention, there is provided a rotor slot and stator slot punching apparatus including a core-rotating core, a core rotating means for sequentially rotating the core at a predetermined angle, A rotor slot punch which is provided on the core rotating means and forms a plurality of rotor slots in the core; a stator slot punch which is provided on the core rotating means and forms a plurality of stator slots in the core; A rotor slot punch, a stator punch, a rotor slot punch, a stator punch, a rotor slot punch, and a stator punch; a punch fixing plate mounted on the rotor slot punch and the stator slot punch to support the rotor slot punch and the stator punch; And a punch holder which is installed between the punch holder and the punch fastening plate, And a punch projecting means for selectively projecting the stator slot punch.
The punch protruding means includes a punch protruding plate which is made of a plate material having a predetermined thickness and accommodates an upper end portion of the rotor slot punch or the stator slot punch and a punch protruding plate which is provided at one side of the punch protruding plate, And a conveying member fixedly coupled to one side of the conveying bar and conveying the conveying bar to the left and right by hydraulic pressure or pneumatic pressure.
Wherein a rotor punch receiving groove formed to be recessed by a predetermined depth and a stator punch receiving groove are formed on the lower surface of the punch projection plate, and the rotor slot punch or the stator slot punch is selectively .
The punch protruding plate may further include a punch detecting member installed at a side of the punch fixing plate for detecting the conveyance of the punch protruding plate.
A rotor slot punch and a stapler slot punch are slidably mounted on a lower portion of the rotor slot punch and the stator slot punch and formed of a plate material having a predetermined thickness and a stripper for pushing the core downwardly during a punching operation And further comprising:
The rotor slot and stator slot punching device according to the present invention has the following effects.
The rotor slot punch and the stator slot punch are selectively protruded in accordance with the left and right movement of the punch plate so that the rotor slot process and the stator slot process are sequentially performed Can be performed at the same time.
Therefore, since the core can be automatically rotated in the disk shape at a certain angle and the rotor slot and the stator slot can be formed on the core at the same time, the conventional rotor slot and the stator slot are much more efficient than those in the other devices, And the operation time can be innovatively shortened.
In addition, if the rotor slot process and the stator slot process are performed at the same time, the core may be deformed. However, since the rotor slot process and the stator slot process can be separately performed, .
