[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for fixing and moving a work, and more particularly to a pallet suitable for moving a stator core to a coil winding device or a coil insertion device.

[0002]

2. Description of the Related Art In working a work, it is sometimes more convenient to carry the work on an appropriate pallet than to carry the work as it is. For example, Japanese Patent Application Laid-Open No.
No. 1-54849, a pallet is provided with a stator core mounting portion and a coil end holding portion. The stator core is mounted on the pallet and transported to a winding device, and the wound coil end portion is held by the holding portion. A technique has been disclosed in which a subsequent energization test or the like can be performed automatically.

[0003]

In such a pallet, it is required that the work can be easily attached and detached. Further, as described in Japanese Patent Application Laid-Open No. 61-54849, it is sometimes required that the work does not drop even if the pallet is turned upside down in the processing operation of the work mounted on the pallet.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a work transfer pallet in which the work can be easily attached and detached and the work does not drop even if the pallet is inverted.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a pallet for fixing and moving a work, the pallet body having a plate shape as a whole, and the work formed on the pallet body. A mounting hole of a size and shape capable of inserting the work, a receiving claw projected to engage the work at the back when the work is inserted into the mounting hole, and disposed on an inner periphery of the mounting hole. A presser plate that elastically presses the outer periphery of the work when the work is inserted into the mounting hole, wherein the presser plate is disposed on the side of the work insertion port with respect to the contact surface with the work. Pivotally supported by a support shaft that is biased toward
It is characterized in that it is constantly urged by an elastic means to rotate toward the insertion port side of the work.

According to the present invention, the stator core is particularly fixed,
It is suitable for a pallet to be moved to a coil winding device or a coil insertion device.

[0007]

According to the pallet of the present invention, when the work is pushed into the mounting hole of the pallet, the holding plate is pushed open against the urging force of the elastic means, the work is inserted into the mounting hole, and the receiving claw is located behind the work. And is supported. And since the pressing plate presses the outer periphery of the work by the urging force of the elastic means,
The work is held without play.

In this state, when the pallet is turned upside down, the portion of the holding plate that makes contact with the work tends to rotate toward the work insertion port due to the gravity of the work. Since the contact surface is in the direction of being pressed more and more against the work, the work is held without falling.

Further, when the work is finished and the work is to be removed from the pallet, the contact surface of the holding plate with the work is rotated so as to rotate deeper into the mounting hole (in the work insertion direction). For example, by pressing the holding plate with a pusher or the like, the pressing of the holding plate to the work is released, and the work can be pulled out from the mounting hole.

As described above, when mounting the work, the work may be pushed into the mounting hole, and when removing the work, the work may be pulled out of the mounting hole while pressing the holding plate with a pusher or the like. The work can be easily removed, and the work does not fall even if the pallet is turned upside down with the work attached.

1 to 4 show an embodiment of a work transfer pallet according to the present invention. FIG. 1 is a perspective view of the pallet viewed from below, FIG. 2 is a plan view of the pallet, FIG. 3 is a side sectional view of the pallet, and FIG.
It is sectional drawing along the IV-IV arrow line.

In FIGS. 1 and 2, reference numeral 11 denotes a plate-shaped pallet body as a whole, and a mounting hole 13 for inserting a stator core 12 is formed in a central portion thereof.
The mounting hole 13 has a size and a shape that allow the outer periphery of the stator core 12 to be fitted and inserted.

As shown in FIG. 3, a receiving claw 14 which engages with the stator core 12 at the back of the mounting hole 13 when the stator core 12 is inserted into the mounting hole 13 from the upper surface A side is provided on the inner periphery of the mounting hole 13. Installed.

A pair of holding plates 21 are arranged on the inner periphery of the mounting hole 13 so as to face each other. The holding plate 21 is appropriately fitted in the notch 15 of the pallet main body 12, an intermediate portion thereof is supported by a support shaft 22, and is rotatable in a vertical direction.

As shown in FIG. 4, one end of the holding plate 21 is
A contact surface 23 extending obliquely downward to the outer periphery of the stator core 12
Has made. The support shaft 22 is arranged closer to the insertion opening of the stator core 12 than the contact surface 23, that is, closer to the upper surface A.

At the other end 24 of the holding plate 21, elastic means 25 made of a spring, rubber or the like is arranged between the holding plate 21 and the pallet body 11, and the elastic means 25 allows the holding plate 2 to be moved.
The one contact surface 23 is constantly urged to rotate toward the insertion port side of the stator core 12, that is, toward the upper surface A.

In the drawing, reference numeral 31 denotes a positioning hole for installing the pallet body 11 in a coil winding device or the like; 32, a guide groove for moving the pallet body 11; 33, a chain for moving the pallet body 11; Numeral 34 denotes rubber for reducing collision between the pallet bodies 11.

In the above configuration, when the stator core 12 is pushed into the mounting hole 13 from the upper surface A of the pallet main body 11, the contact surface 23 of the holding plate 21 rotates toward the lower surface B against the elastic means 25. Then, the stator core 12 is inserted into the mounting hole 13, and is engaged with and supported by the receiving claw 14 protruding from the mounting hole 13. And the holding plate 21
The elastic member 25 presses the contact surface 23 against the outer peripheral surface of the stator core 12.
Is firmly held without play.

In this state, when the pallet body 11 is turned upside down, the stator core 12 tends to fall out of the mounting hole 13, but at this time, the contact surface 23 of the holding plate 21 is turned to the insertion opening side (A side). As a result, the contact surface 23 of the holding plate 21 is more and more pressed against the outer periphery of the stator core 12. As a result, even if the pallet body 11 is turned upside down, the stator core 12 is securely held without dropping out of the mounting hole 13.

On the other hand, after the predetermined winding is applied to the stator core 12, when the stator core 12 is to be removed, the upper surface A of the pallet body 11 is directed upward.
When the other end 24 of the holding plate 21 is pushed up against the elastic means 25, the contact surface 23 of the holding plate 21 rotates to the lower surface B side,
The pressing on the stator core 12 is released. In that state,
If the stator core 12 is held by a clamp or the like and pulled up,
The stator core 12 can be pulled out from the mounting hole 13.

[0021]

[Effects of the Invention] As described above, according to the work transfer pallet of the present invention, when mounting a work, it is sufficient to push the work into the mounting hole, and when removing the work, push the holding plate with a pusher or the like. Since the work only needs to be pulled out of the mounting hole, the work can be easily mounted and removed, and the work does not drop even if the pallet is inverted with the work mounted. Therefore,
Work can be quickly attached and detached, and productivity can be increased.
