For example, a structure as disclosed in JP-A-1-91609 is known.
Since the clamping mechanism for fixing the wire so that it does not move and the coating stripping mechanism for stripping off the wire coating are combined into a single tool, there is first the wire clamping step, and then the wire coating. It is a two-step system where the stripping process continues, the structure is complicated, it is difficult to reduce the weight,
Moreover, there is a drawback that the manufacturing cost is high.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art. The two-step system described above can be carried out in one step while holding the electric wire at the same time. An object of the present invention is to provide an electric wire stripping device capable of stripping an electric wire coating, having a simple structure and being manufactured at low cost.

[0004]

Means for Solving the Problems An electric wire stripper of the present invention is:
With the cutting blade holder and the wire tightening guide as the main parts, the cutting blade holder always stops at the position of the opening where the wire can be attached and detached by the rotation stop claw, and the rotation stop claw always returns to the predetermined position by the spring force. The tip of the wire is fitted into a shallow groove provided on the outer edge of the cutting blade holder, and the wire tightening guide has one end in contact with the cutting blade holder and stops at the opening position. It is rotated by an external force, its edge portion pushes the cutting blade holder, the detent claw is disengaged from the shallow groove, the cutting blade holder is rotated, and the electric wire is covered by the cutting blade attached to the cutting blade holder. Is configured to be stripped off.

Therefore, when an external force is applied to the wire tightening guide after mounting the wire through the opening, the wire tightening guide rotates and acts as a driving force for rotating the cutting blade holder, and at the same time, the wire tightening guide works. Since the electric wire is sandwiched between the cutting blade holders and acts as an electric wire clamping tool, it is not necessary to newly provide an electric wire clamping tool, so that the structure of the electric wire peeling device is simplified.

Therefore, when the driven gears 12 and 12 ′ rotate, the oilless metal shaft 11 rotates to rotate the electric wire tightening guide 7, but the cutting blade holder 1 does not rotate following the rotation of the oilless metal shaft 11. The OILES metal shaft 11 has a notch at the position of the opening 4 so that the electric wire 3 can be attached and detached.

Reference numeral 15 is a drive gear, which is a driven gear 12, 1
The driving gears 2 and 12 'are rotated by receiving a driving force from a driving unit such as a manipulator and rotate the driven gears 12 and 12'. The driven gears 12 and 12 'are notched at the position of the opening 4 so that the electric wire 3 can be attached and detached.

The driven gears 12 and 12 'rotate in mutually opposite directions, but the driven gear 12 is designed so that the cutting blade 9 mounted on the cutting blade holder-1 can strip the coating 10 of the electric wire 3. ~ It rotates in the direction shown by the arrow in FIG.

In FIG. 6, reference numeral 16 denotes an idle gear, which meshes with the driven gears 12, 12 'on the back side of the position of the opening 4. Accordingly, the idle gear 16 is constantly rotated by receiving the driving force from the driven gears 12 and 12 ′. For example, when the notch of the driven gear 12 comes to a position where it meshes with the drive gear 15, the idle gear 16 is driven.
No driving force is transmitted from the drive gear to the driven gear 12, but the idle gear 16 drives the driven gear 12 to keep the driven gear 12 rotating.

In FIG. 5, reference numeral 17 denotes a reversing claw having a ratchet function for stopping the device at a fixed position by rotating the device in the opposite direction.
Meshes with the notch 20 provided at a predetermined position of
When the stripping of the electric wire 3 is completed and the instrument is rotated in the direction opposite to the arrow shown in FIGS. 2 to 4, the reverse claw 17 operates to stop the instrument at the position of the opening 4. At this time, the wire tightening guide 7 is reversed and hits the end face of the cutting blade holder-1, and the cutting blade holder-1 is rotated in the opposite direction so that the whirl-stop pawl 2 is fitted into the shallow groove 6 of the cutting blade holder-1. Then, the cutting blade holder-1 is stopped at the original position.

Reference numeral 18 is a case, and reference numeral 19 is a mouthpiece portion connected to a drive portion such as a manipulator for transmitting the drive force to the drive gear 15.

In practice, first, the electric wire 3 is mounted through the opening 4 at the position shown in FIG. Next, drive gear 15
As shown in FIG. 3, the electric wire tightening guide 7 rotates to clamp the electric wire 3 between the cutting blade holder-1 and the electric wire tightening guide 7, and the edge portion 8 causes the cutting blade holder-
