Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a winding nozzle finishing device, and in particular, to an apparatus for automatically finishing the through-hole of a nozzle and its both end faces by wrapping without any manual intervention. It concerns new improvements.

b. Prior Art Conventionally, as a means for lapping (polishing) the through hole of a nozzle for guiding the winding wire in a winding machine, as shown in FIG. A wrapping thread 3 containing a wrapping material (not shown) is passed through the through hole 2, one end of which is fixed to the fixing part 4, and the other end is held by hand 5, and the nozzle 1 is manually moved from side to side. By reciprocating, the wrapping thread 3 and the through hole 2 slide, thereby completing the wrapping inside the through hole 2.

c Problems to be solved by the invention Since the conventional nozzle wrapping finishing means was constructed as described above, the finished shape of the through hole of the nozzle 1 and its end surface 2 was irregular, resulting in extremely poor yield. .

Furthermore, since the wrapping process was done manually, the wrapping process took a very long time, resulting in extremely low productivity.

The object of the present invention is to eliminate the above-mentioned problems and, in particular, to provide a winding nozzle finishing device for automatically wrapping and finishing without relying on manual labor.

d Means for Solving the Problems The winding nozzle finishing device according to the present invention includes a wrapping yarn supply section 10 having a wrapped wrapping yarn 3, a winding reel 19 for winding the wrapping yarn 3, and a winding reel 19 for winding the wrapping yarn 3. A brake means 12 provided in the wrapping thread supply section 10 and a spring member 15 for biasing the wrapping thread supply section 10 in one direction.
and a spindle 6 which has a nozzle holder 8 on its upper part for holding the nozzle 1, which is the workpiece through which the wrapping thread 3 has passed, and is vertically movable and rotatable.
and a connecting body 20 provided on the spindle 6,
a connecting shaft 21 connected to the connecting body 20; a gimbal ring 2 in which the connecting shaft 21 is slidably connected to the connecting shaft 21 in the axial direction of the connecting shaft 21;
2. A gimbal holder 26 provided on the gimbal ring 22, and a gimbal holder 26 so that the amount of eccentricity of the gimbal holder 26 can be adjusted through a long hole 29 formed in the gimbal holder 26.
The spindle drive mechanism 31 includes a drive shaft 28 connected to the drive shaft 28 and a drive motor 28a that rotates the drive shaft 28.

e Effect In the winding nozzle finishing device according to the present invention, the spindle performs a combined vertical and rotational movement by the spindle drive mechanism, so the nozzle holder performs an elliptical locus motion, and the nozzle attached to this nozzle holder also moves. A similar operation can be performed. Therefore, when the wrapping yarn passing through the through-hole of this nozzle is wound up by the wrapping yarn winding section, the wrapping yarn in a new state passes through the through-hole one after another, and the elliptical locus movement of the nozzle causes the wrapping yarn to be wrapped in a new state one after another. ,
The wrapping thread is slidably joined to the entire inner surface and end surface of the through hole in the nozzle, and a wrapping operation of a desired shape is performed.

A biasing means 15 made of a spring member is provided between the base 13 and the main body 14, and the wrapping thread supply section 10 is always urged toward the main body 14 by the return force of the urging means 15. In the above-mentioned configuration, in order to prevent the wrapping yarn 3 from sagging, the pressing force by the brake means 12 is configured to be greater than the spring force of the biasing means 15.

The other end of the wrapping thread 3 passes through a wrapping thread fixed position holding section 16 and is wound up by a winding reel 19 of a wrapping thread winding section 18 having a winding motor 17.

Furthermore, a connecting body 20 is provided approximately at the center of the spindle 6, and a connecting shaft 21 connected to this connecting body 20 is connected to a gimbal ring 22, which is entirely ring-shaped, as shown in FIG. The connecting shaft 21 is connected via a sliding ring 21a to a gimbal shaft 24 which is rotatably provided through a bearing 23 to be slidable along the axial direction Y of the connecting shaft 21.

A pair of attachment parts 27 of a gimbal holder 26 are movably attached to a bearing 25 formed on the periphery of this gimbal ring 22, and the bearing 25 of this gimbal holder 26 and the bearing 2 of the gimbal shaft 24
3 are disposed perpendicularly to each other, and this gimbal ring 22 has a connection action and a mechanical transmission/conversion action substantially similar to a universal joint with respect to the connection shaft 21 and gimbal holder 26. .

A drive shaft 28 rotated by a drive motor 28a is connected to the lower end of the gimbal holder 26, and a long hole 2 formed in the gimbal holder 26 is connected to the lower end of the gimbal holder 26.
By connecting via a mounting nut 30 provided at the gimbal holder 9, it is possible to freely adjust the amount of eccentricity (that is, the eccentric stroke) between the drive shaft 28 and the gimbal holder 26. Therefore,
By loosening this mounting nut 30, the gimbal holder 26 can be freely positioned in the direction of arrow B. Therefore, the aforementioned gimbal ring 22, gimbal holder 26, drive shaft 2
8 and the drive motor 28a constitute a spindle drive mechanism 31.

The winding nozzle finishing apparatus according to the present invention is constructed as described above, and its operation will be explained below.

The nozzle 1, which is a workpiece, is attached to the nozzle holder 8, and the wrapping thread 3 is passed through the through hole of the nozzle 1 and wound around the winding reel 19 of the wrapping thread winding section 18.
