Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding machine for a linear pulse motor that provides automatic winding means as a means for creating windings for supplying pulse signals. .

Conventionally, in this type of winding work, for example, when the distance between magnetic poles is narrow, such as 4.6 songs,
Winding was done exclusively manually. The present invention provides a means for automatic and continuous winding even in such cases. This will be explained below according to the drawings.

A spindle 1 is provided with appropriate means to move up and down and rotate forward and backward over a required angle.

2.3 is a ball bearing, and the ball bearing 2.3 is used to conveniently determine the position of a swing lever, etc., which will be described later, via a slider 5 that is inserted into the spindle 1 with a set screw 4.
It has a U-shaped cross section and also includes a lower movement support fitting 7 to facilitate displacement of the spindle 1 in the longitudinal direction.

Furthermore, the upper and lower movement support fittings 7 are arranged so that the cam followers 6.6 (see FIGS. 1, 3, and 5) arranged on the − side are symmetrically attached to the side wall 7Wf! : Fixed by a bolt, nut, etc. passing through the threaded hole 6 [3, 6C] and the cam follower 6.
The cam 7 follower 6 is held by 6 people, and the cam 7 follower 6.6 is guided linearly along the guide gG to prevent the upper and lower movement support fittings 7 from swinging during upward and downward movement. A cam follow guide 8 is arranged.

9.10 is a collar, which passes through the upper and lower movement support fittings 7 and is located under the bearing 2.3 fitted to the spindle 1, with an opening M, (see Fig. 5) and an opening fL, respectively. The bushing 11 is placed between the collars 9 and 10, and the spindle l is inserted into the bushing. One side of the swing lever 13 is fitted and fixed by a set screw 11λ. Reference numeral 14 denotes a guide support fitting (see Fig. 6) that includes the nozzle 15, 15 people, etc. The guide support fitting 14 is formed into a substantially gate shape, and the upper surface g1
An oval hole 17 is formed in the center of the hole 6, and long holes 18B are formed on both sides of the oval hole 170.
In order to incorporate the upper and lower movement support fittings 7, the spindle 1 has upper and lower through holes 7H → ball bearing 2.3 → oval hole 17. It is fixed via a ball bearing nut 18, and is screwed into the mounting screw holes 6D and 6E provided in the downward movement support fitting 7 above the button. The shaft support fitting 14 is constructed so as to form a body (see FIG. 3). Reference numeral 20 designates a nozzle holder, and as shown in FIG. The linear bushings 22, 22, and 23A that are inserted into the guide shafts 22, 22, and 23A are threaded through the mounting holes 25A→25B and 26A→26B provided in the side wall 24.24A that forms the opening formed in the guide shaft support fitting 14, respectively. The wire W that is installed and inserted into the nozzle 15 is spun together with the nozzle 15.15A.

It swings linearly (transversely) between the side walls 24, 24A corresponding to the rotation angle of the lever 1.

34 to 37 shown in FIG. 4 are stop rings, which are guided through the linear bush 22N and the linear bush 22 to
, 23. P□ to P4 (see the seventh figure) are the magnetic poles of the linear pulse motor, and these magnetic poles are attached to the feed base 30 by appropriate means, for example, the electric motor MKI
A vertical feed screw 31 and a horizontal feed screw 3 provided for the rolling wheels 32
3, the feed base 30 is displaced back and forth and left and right.

The electric motor M is energized and the magnetic pole P1. In order to wind the wire W around P, vertical feed is applied, and then the rolling wheels are operated and horizontal feed is applied, so that one side of the wire W is fixed to the nozzle 15.15.
A is arranged as shown by the chain line (see Figure 7). Therefore, by continuing to give the spindle 1 (see Fig. 3, 7) upward and downward motions and rotation angle movements over the required angles, the magnetic poles P and P2 are caused to reverse by these acid-containing movements. Wire W is wound on the clockwise side and it is 11w! Coupled with the biasing of the screw, the coils C1 and C3 are formed over the required length and width. Next, the motor M is energized and the magnetic pole p1. p.

and then the magnetic pole P2. The wheel 32 is operated so that P can wind the coil, and then the nozzle 15° is energized by the feed screw 31, and the magnetic field is moved between the magnetic poles P, , and P3.
The nozzle 15115A is placed between the right sides of the magnetic pole P4 and placed together, and then the spindle 1 is given upward, downward and 611 movements in the opposite direction (see FIG. 8), and the vertical feed screw 31 is energized. Coupled with this, the magnetism of the wire W K P 2 * P
4. The winding for VC is oriented around 11', forming coils C2 and C4. Spindle 1 for forming these coils 01 to C4. A suitable control circuit (not shown) is used to control the movement of the carriage 30.

In the present invention, in order to form the coils C□ to C4 in a rectangular coil pattern, when the spindle 1 rotates through a required angle, the swing lever 1 moves as shown in FIG.
Since the displacement of 3 causes the nozzle holder 20 to be continuously displaced in the horizontal direction along the guide shafts 23 and 23 through the spherical bush 13, the nozzle A is closed.

In addition to the fact that the wire W being fed out from the wires 15 and 15pF9 is also edged out in the horizontal direction, the up and down movement of the spindle 1 creates a magnet with a rectangular cross section.
In addition, the present invention has the advantage that the wire W is wound steadily along the circumference of the coil, and the width of the coil winding can be easily adjusted as shown in FIG.
