Description

Coil Forming Device of Motor Stator

The present invention relates to a coil forming apparatus of a motor stator, and more particularly, to a coil of a motor stator capable of simultaneously forming an inner diameter, an upper height, an upper outer diameter, a lower height, and a lower outer diameter of a coil wound on a stator. It relates to a forming apparatus.

A motor generally refers to a mechanical device that converts electrical energy into mechanical power. Such a motor usually includes a housing, a stator fixed inside the housing, and a rotor rotatably supported with the stator. It is an essential component.

Although the stator and the rotor have a slight difference depending on the type of motor, a coil is wound around the laminated core, and a current flows through the coil to generate a magnetic field in the laminated iron core, and the stator core and the rotor As the rotor rotates by the interaction of the magnetic field generated in the core, electrical energy is converted into mechanical power.

In this way, the motor is wound around the stator so that the coil wound around the stator is mounted inside the housing and the rotor rotates inside the stator so that the housing and the coil wound around the rotor and the stator do not interfere with each other. There is a need to form coils within certain dimensions.

Since the forming of the stator coils usually requires a large force, it is common to use a mechanical device rather than by hand. In the related art, the forming of the stator coils is performed to expand the inner diameter of the coil, and the upper height and upper side of the coil. Since the work of forming the outer diameter and the work of forming the lower height and the lower outer diameter of the coil were performed in separate machines, not only a large number of process steps are required for the forming of the coil, but also a separate worker for each process. There was a problem that there should be.

Therefore, the technical problem to be achieved by the present invention, that is, the object of the present invention is to solve the above problems of the coil forming operation of the conventional motor stator, the inner diameter of the coil, the upper height, the upper outer diameter, The present invention provides a coil forming apparatus for a motor stator capable of simultaneously forming a lower height and a lower outer diameter.

As it moves toward the lower height forming jig 62 while compressing, the lower outer diameter forming jig 64 is transported radially inward, and the lower height forming jig 62 is formed by a plurality of fourth elastic members 73. It is biased radially outward from the center of.

Here, the stator feed actuator 30, the upper jig lift actuator 50 and the lower leg lift actuator 60 is preferably a hydraulic cylinder, respectively.

According to the coil forming apparatus of the motor stator according to the present invention configured as described above, the coil is a work object in the stator receiving portion 22 of the stator seating jig 20, the operator is located at the stator supply position (see Fig. 1) After mounting the wound stator 80 and pressing the operation switch (not shown), the stator transfer actuator 30 is operated, so that the stator seating jig 22 coupled to the front end of the piston rod has a frame ( 10) is transferred to the coil forming position (see FIG. 2) along the guide rail 21 attached thereto.

When the transfer of the stator 80 to the coil forming position is completed, the upper jig elevating actuator 50 is operated, and the upper jig assembly 40 starts to descend, and thus the upper height of the upper jig assembly 40 is increased. The inner diameter expansion jig 43 provided below the center of the forming jig 42 begins to expand the inner diameter of the stator 80 coil (see FIG. 3).

When the upper jig lifting actuator 50 is advanced and the upper height forming jig 42 is further lowered, the groove formed on the lower surface thereof starts to contact the upper end of the stator 80 coil, and the upper height forming jig 42 ) Is lowered until the lower surface contacts the upper jig stopper 23 provided on the upper surface of the stator seating jig 20, and the upper side of the coil is formed to have a predetermined height by the force of the first elastic member 46. (See Figure 4).

Even if the lower height jig 42 is lowered by the upper jig stopper 23 of the stator seating jig 20, the upper jig lifting actuator 50 continues to move forward, and thus the upper jig lifting actuator The upper jig bracket 41, which is connected to the tip of the piston rod of 50, begins to descend while compressing the first elastic member 46.

When the upper jig bracket 41 begins to descend while compressing the first elastic member 46, the upper outer diameter forming jig pusher 45 fixedly coupled to the lower surface of the upper jig bracket 41 is lowered. Therefore, while the inclined surface 45a formed on one side of the lower side thereof contacts the inclined surface 44a of the upper outer diameter forming jig 44, the upper outer diameter forming jig 44 is pressed radially inward, and thus the upper side The outer diameter forming jig 44 slides radially inward to form the upper outer diameter of the stator 80 coil into a predetermined shape (see FIG. 5).

As such, when the expansion of the inner diameter of the coil and the forming of the upper height and the upper outer diameter are completed, the lower leg jig actuator 70 is operated to start the lower jig assembly 60 to rise, and thus the lower jig assembly 60. Grooves formed on the upper surface of the lower height forming jig 62 begin to contact the lower end of the stator 80 coil to start forming the lower height of the coil.

The lower height forming jig 62 is raised until the upper surface thereof comes into contact with the lower jig stopper 24 provided on the lower surface of the stator seating jig 20. Foaming is performed to a predetermined height (see FIG. 6).

Even if the lower height forming jig 62 is prevented from being raised by the lower jag stopper 24 of the stator seating jig 20, the lower leg lifting actuator 70 continues to move forward, and thus the lower leg lifting actuator The Hajig Bracket 61 connected to the tip of the piston rod of 50 starts to rise while compressing the third elastic member 66.

When the haggig bracket 61 begins to descend while compressing the third elastic member 66, the lower outer diameter forming jig pusher 65, which is fixedly coupled to the upper surface of the hagig bracket 61, is raised. Therefore, while the inclined surface 65a formed on one side of the upper side thereof contacts the inclined surface 64a of the lower outer diameter forming jig 64, the lower outer diameter forming jig 64 is urged radially inward, and thus the lower side As the outer diameter forming jig 64 slides radially inward, the lower outer diameter of the stator 80 coil is formed into a predetermined shape (see FIG. 7).

As such, when the forming of the inner diameter, the upper height, the upper outer diameter, the lower height, and the lower outer diameter of the coil of the stator 80 mounted on the stator seating jig 20 is completed, the leg rest lifting actuator ( 70), the upper jig elevating actuator 50, and the stator feeding actuator 30 are sequentially operated, so that the stator feeding jig 20 is returned to the stator ejecting position, that is, the stator feeding position (see FIG. 1). The worker completes the series of work by taking out the stator 80 having completed forming.
