Abstract

PURPOSE:To make the setting of an upper drum ever so easy as well as to facilitate handling for a winding jig in time of automatic winding operation, by attaching both upper and lower drums to a winding shaft via a steel ball and a clamp screw, while installing an end wire holder which holds the terminal of a stranded wire coiled in dislike form. CONSTITUTION:In time of winding operation, an end wire holder 11 is locked to a G position in advance. And, first an initial wire 18 of a stranded wire 1 is set to a position where it should be, while both upper and lower drums 2 and 3 being secured to the initial wire 18 by a winding shaft 5 is rotated in an H direction, and the stranded wire 1 is thus wound up. Then, a block 14 is shifted to an I direction, inserting the end wire holder 11 into a notch hole 20, and a winding outer diameter of the stranded wire 1 is pressed to a C direction, then the stranded wire is cut off from outside at a J position. Thus, the stranded wire 1 is solidified upon self-fusion, and after that, a clamp screw 8 is loosened to some extent in an L direction whereby a steel ball 6 is pressed toward a K direction by a drop preventing spring 7. With this constitution, the upper drum 2 is separated from the winding shaft 5, and the stranded wire 1 is lifted from a notch 17 in the L direction, thus it is taken out as a product.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention automatically winds stranded wire into a disk shape using a winding machine, and then holds the stranded wire in a disk shape until self-fusion. This invention relates to a jig for winding stranded wire.

Structure of the conventional example and its problems The conventional stranded wire winding jig, as shown in Fig. 1, has a specific structure, in which the winding shaft 5 is attached to the main shaft of the winding machine, and after winding, the upper drum 2 and the lower The drum 3 was held by a clamper 6, the nut 4 was loosened, the state was separated from the winding shaft 5, and the state was transferred to the next step and self-fused. With a configuration like this,
The wire shaft 4 had to be completely pulled out from the winding shaft 5, which made separation and assembly difficult.

There were also problems in terms of cost, making it unsuitable for automation.

The present invention solves the above-mentioned conventional drawbacks, and improves reliability, low cost, and workability in automatic winding of a stranded wire winding machine. .

Structure of the Invention The stranded wire winding jig of the present invention includes an upper drum and a lower drum that serve as guides for the stranded wire when winding the stranded wire into a disk shape, and the upper drum and the lower drum are connected to the main shaft of the winding machine. It is characterized by consisting of a winding shaft that allows installation, a steel ball and tightening screw that allows the upper drum and lower drum to be assembled to the winding shaft, and an end wire holder that holds down the end of the stranded wire wound into a disk shape. shall be.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In FIG. 2, 1 is a product in which twisted wires are wound onto a disc and self-fused. In Figure 3, 1 is a stranded wire that is wound while being guided by an upper drum 2 and a lower drum 3, and 6 is the above-mentioned stranded wire, which holds the upper drum 2 and lower drum 3 at the center of the winding and can be attached to and detached from the main shaft of the winding machine. a winding shaft held in
The winding shaft 6 fixedly holds the upper drum 2 and the lower drum 3, the steel balls 6, a tightening screw 8 for pushing the steel balls 6 in the incoming direction, a spring 7 for preventing the steel balls 6 from falling, and the upper drum 2. It has a pin 9 for positioning the lower drum 3 in the B direction. Reference numeral 10 denotes a regulating disk for regulating the inner diameter of the winding diameter of the stranded wire 1, and is fixedly fastened to the lower drum 3. Reference numeral 11 denotes an end wire presser that presses the outer diameter end of the winding diameter of the stranded wire 1 in the C direction, and the above-mentioned end wire presser 1.
1 is held slidably in the D direction via the upper and lower guides 12, and is held slidably in the E direction by the front and rear guides 13.

14 is a pro-I lever that holds the upper and lower guides 12 fixedly;
16 is a compression spring that presses the end line presser 11 in the F direction, and 16 is a tension spring that moves the end line presser 11 in the C direction.

The front and rear guides 13 mentioned above are fixed to the upper drum 2. The lower drum 3 has a protruding hole 17 through which the stranded wire 1 is taken out in its disk shape, and a cutout hole 19 through which the stranded wire 18 at the beginning of winding is guided to the regulating disk 10. Further, the upper drum 2 has a notch hole 20 at the same position as the notch hole 19, which allows the edge line presser 11 to move in the D direction.

The operation of the stranded wire winding jig constructed as described above will be explained below.

First, before winding, the end wire presser 11 is fixed at position a. Twisted wire 18 at the beginning of winding of stranded wire 1 in the above set state
is set, and the winding jig is rotated in the H direction via the main shaft of the winding machine to wind up the stranded wire 1.

In the above-mentioned wound state, by moving the block 14 in the r direction, the end wire presser 11 is inserted into the notch hole 20, and presses the winding outer diameter of the stranded wire 1 in the C direction. more disconnected. After the stranded wire is fixed by self-fusion tζ in the above state, by loosening the tightening screw 8 in the L direction, the steel ball 6 is pushed in the direction by the fall prevention spring 7. In the above state, the upper drum 2 is separated from the winding shaft 5,
The stranded wire 1 is lifted from the notch 17 in the L direction and taken out as a product. To assemble the jig, after removing the stranded wire 1, set the upper drum 2 and move the tightening screw 8 in the F direction to push out the steel ball 6 in the A direction.
The upper drum 2 and the lower drum 3 are fixedly held on a winding shaft 6.

As described above, according to this embodiment, only the upper drum 2 is completely separated from the winding jig, and it is easy to handle during automatic winding. This makes it possible to move on to the process, which is extremely advantageous in terms of construction methods. Also, mass production becomes possible.

Effects of the Invention As described above, according to the present invention, since only the upper drum is completely separated from the winding jig, it is easy to handle and suitable for automation. Furthermore, it is extremely advantageous in terms of the construction method because it can be used as a winding jig until the final process in a wound state.

In addition, it is easy to attach and detach the stranded wire from the winding jig, and it is easy to assemble the winding jig. It is easy to carry out, and as a mass production jig, its effectiveness is outstanding.
