Problems solved by technology

Therefore, a large cam mechanism is necessary, which makes it difficult to move at a high speed and cannot be wound at a high speed. The manufacturing time of the armature is prolonged and the production efficiency is low.
In addition, in this technology, the orbit of the needle tube can be changed in a limited range, and when the insulator is changed, there will be a problem that the orbit that is most suitable for the changed insulator cannot be circulated.

Embodiment 1

[0116] First refer to figure 2 , to illustrate the state of winding the coil wires on the magnetic pole teeth 71 of the stator core 70 with a direct-wound winding machine, and the overshoot that easily occurs when the traditional winding machine winds at high speed. To make figure 2 (A) is easier to understand, and a part of the stator core and the tip of the inner cylinder 60 for guiding the coil wire are described in a perspective view. In addition, the imaginary line of the inner cylinder 60 is shown by the dashed-dotted line. The stator core 70 is composed of a plurality of laminated thin plates, and insulators 80, 80 are installed on the upper and lower end surfaces thereof.

[0117] The stator core 70 is penetrated by slots 73 through which the magnetic pole teeth 71 protruding inwardly formed in the stator core are interposed and the coil wires are wound. The inner side of the magnetic pole teeth 71 is formed as a flange portion 72 protruding in the circumferential d...

[0141] Then refer to Figure 6 , illustrating that the needle circulation assembly 2 of the circulation track is controlled by the circulation track control assembly when corresponding to insulators of different shapes. Figure 6 Figure (A) shows an example of the cyclic motion of an insulator suitable for an upstanding wall 82 in the shape of a narrow hexagon above which the upper side is parallel to the lower side and connected to a vertical line by a hypotenuse.

[0142] Specifically, in order to correspond to only the length of the vertical line (refer to Figure 6 (A) figure) the insulator which has the vertical wall 82 of a substantially trapezoidal shape by extending the length a, and changes the example of the circulating track. Figure 6 The (B) diagram shows the synthesis to Figure 6 (A) Diagram of the orbital offset of the pendulum motion of the tip of the needle. Figure 6 The (C) diagram shows the synthesis to Figure 6 (A) Diagram of the trajectory of the of...

Embodiment 3

[0147] In Example 3, refer to Figure 7 , illustrating that the position of the top of the circulating track controlled by the circulating track control component is changed toward the starting end side of the swing movement. Figure 7 The demand line shown in (A) is the state where the position of the vertex before the change is still positioned at the center of the magnetic pole teeth, and the solid line shows that the position α of the vertex after the change is moved closer to the center of the magnetic pole teeth. The state of the originating side. In addition, the position of the vertex before the change of the cyclic orbit is shown by a chain circle.

[0148] Figure 7 The dotted line shown in (B) is the position change of the swing motion before the top position is changed, and the solid line is the position change of the swing motion when the top position α moves from the center of the magnetic pole teeth to the starting end side of the swing motion. Figure 7 The ...

Abstract

The invention provides a needle circling means and a series winding-type winding machine that comprises said needle circling means, wherein winding can be performed at a high speed, a coil wire that has been wound has high alignment accuracy, and when an insulator of a different shape is used, the trajectory of a needle can be changed without rearranging the winding machine. A servo motor for linear motion and a servo motor for oscillating motion are made to rotate only in one direction, and each servo motor is fixed to a base in an independent manner. Additionally, a circling trajectory control means controls the speed of the rotational motion of each servo motor and allows the circling trajectory of a tip of a needle to be changed.

Description

technical field [0001] The present invention relates to a winding machine for winding a coil wire on a magnetic pole tooth by direct winding from the inner diameter side of a stator core having a circular cross-section having a plurality of magnetic pole teeth inside. Specifically, it relates to a needle tube circulation assembly that drives the tip of a thin cylinder (hereinafter referred to as "needle tube") that sends out coil wires to move in an elliptical orbit around the magnetic pole teeth, and a needle tube circulation assembly that includes the needle tube circulation assembly. thread machine. In detail, it relates to a needle tube circulation assembly that can be wound at high speed, and the wound coil wires have high alignment accuracy. When using insulators of different shapes, it is not necessary to replace the combination of the winding machine, and the needle tube track can also be changed. And a direct winding winding machine including the needle tube circulat...
