DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire stripper, and more particularly, to an uninterruptible power distribution line.
The present invention relates to a structure of a wire stripper devised so as to be applicable to a wire stripping operation using a manipulator or the like.

[0002]

2. Description of the Related Art Conventionally, this type of wire stripper has been
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 stripping mechanism for stripping the wire coating are integrated into one tool, there is a wire clamping process first, and then the wire coating. This is a two-step system in which the stripping step is continued, and has the drawbacks that the structure is complicated, the weight is difficult to reduce, and the manufacturing cost is high.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the drawbacks described in the prior art, and it is necessary to simultaneously hold the electric wires while holding the electric wires so that the two-step system can be performed in one step. It is an object of the present invention to provide a wire stripper for a manipulator capable of stripping a wire coating by a predetermined length.

[0004]

SUMMARY OF THE INVENTION A wire stripper for a manipulator according to the present invention is such that if a wire is tightened with a wire tightening guide, the cutting blade holder is rotated and the cutting blade mounted on the cutting blade holder is used. While stripping the wire, the wire tightening guide and the cutting blade holder are retracted by a predetermined length, and only the wire coating corresponding to the retracted predetermined length can be stripped. It is assumed that.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS.
A cylindrical rotary sliding shaft 2 provided with a notch 1 for attaching and detaching an electric wire in the axial direction has a driving gear 9, a driven gear 10, 10 ', idle gears 11, 11', and a notch 1. Driven gear
The drive shaft is connected to a drive shaft (not shown) via a gear system such as meshing mechanism 12 and can be moved forward and backward while rotating by switching the rotation direction of the drive shaft. That is, a male screw 13 and an axial key groove (not shown) are formed on the outer periphery of the rotary sliding shaft 2. The male screw 13 is screwed with a female screw 15 formed on the inner surface of the support plate 14. A key 16 fixed to the driven gear 12 is slidably fitted in the axial groove of the rotary sliding shaft 2. Therefore, when the driven gear 12 rotates, the rotary sliding shaft 2 receives a driving force from the driven gear 12 via the key 16 and rotates. However, the male screw 13 of the rotary sliding shaft 2 is supported by the support plate. Since the support plate 14 is stationary with the female screw 15 engraved on the inner surface of the port 14, the rotary sliding shaft 2 can move left and right while rotating, that is, advance and retreat. Has become.

As shown in FIGS. 1 and 2, the cutting blade holder 4 is connected to the rotary sliding shaft 2 so as to form an opening 3 for attaching and detaching an electric wire at a position corresponding to the notch 1 of the rotary sliding shaft 2. 2 is rotatably fitted to the distal end of the rotary sliding shaft 2, and one end of the wire tightening guide 5 is in contact with the cutting blade holder 4 and is fixed to the distal end of the rotary sliding shaft 2. Accordingly, the electric wire tightening guide 5 immediately starts rotating in conjunction with the rotation of the rotary sliding shaft 2, but the cutting blade holder 4 is, as shown in FIG. The electric wire tightening guide 5 is stationary until the edge 8 of the electric wire tightening guide 5 rotated in conjunction with the rotation hits the cutting blade holder 4, and then the electric wire tightening guide 5 serves as a locomotive. -4 is pressed and rotated.
FIG. 2A shows an initial positional relationship between the cutting blade holder 4 and the electric wire tightening guide 5.

A wire 6 is mounted through the opening 3 and a cutting blade holder
In the direction in which the cutting blade 7 attached to 4 strips the coating of the electric wire 6,
When the rotary sliding shaft 2 is driven, the rotary sliding shaft 2 retreats while rotating, and in conjunction with this, the wire tightening guide 5 also retreats while rotating. Hits the cutting blade holder 4, pushes the cutting blade holder 4 around, and while the cutting blade 7 peels off the coating of the electric wire 6, the predetermined length (effective of the male screw 13 of the rotary sliding shaft 2 When the plunger is retracted by the length of (screw length), as shown in FIG.
At 18, the front rear end face of the rotary sliding shaft 2 abuts, and the rotary sliding shaft 2 idles, and by this idle rotation, the cutting blade 7 cuts off the swarf of the spirally cut electric wire 6, Let it fall. Next, the reaction force of the spring 17 exerts a force to push back the front rear end face of the rotary slide shaft 2. Therefore, when the drive shaft is rotated in the reverse direction, the male screw 1 of the rotary slide shaft 2 is rotated.
3 easily bites into the female screw 15 of the support plate 14,
When the drive shaft is rotated reversely by the stopper 19 until the advance of the rotary sliding shaft 2 stops, the rotary sliding shaft 2 automatically returns to the original position. In addition, FIG.
In FIG. 4, 20 is a shaft, 21 is a detent pawl, 2
2 is a member fixed to the edge of the cutting blade holder-4, and 23 is a shallow groove.

[0008]

As described above, the present invention is configured as described above, so that a wire covering of a predetermined length can be simultaneously stripped off while holding the wire.
