BRIEF DESCRIPTION OF THE DRAWINGS FIG.

In FIG. 1, reference numeral 20 denotes a peeling cutter as a whole, and a base 21 is rotatably driven by a predetermined actuator (not shown). A support member 22 is fixed to the base 21 so as to be integral with the base 21. The base 21 and the support member 22 are provided with through-holes 23 penetrating through the central portion, so that the wire 3 having the insulating film formed in the through-holes 23 is inserted in the peeling cutter 20. I have.

An arm 24 extending in the longitudinal direction of the wire 3 is attached to the support member 22 by a fulcrum 25 so as to be swingable in a direction perpendicular to the rotation axis direction. One end of the arm 24 protrudes forward from the tip of the support member 22 (the forward direction of the wire A is the forward direction), and a cutter 26 facing the wire 3 is attached to this one end. On the other hand, a governor 27 having a predetermined weight is attached to the other end of the arm 22. One end of a coil spring 28 is attached to the support member 22, and the other end of the coil spring 28 is attached to the arm 24 at a position between the fulcrum 25 and the cutter 26, whereby the arm 24 is attached to the coil spring 28. Thus, it is biased clockwise.

As a result, in the peeling cutter 20, the base 21, the support member 22, and the arm 24 rotate around the wire 3 integrally, and at this time, the arm 24 rotates at the fulcrum 25 based on the centrifugal force generated in the governor 27. Is rotated counterclockwise about the center of rotation. As a result, in the peeling cutter 20, the cutter 26 turns around the wire 3 while abutting on the wire 3, and thereby the wire 3
Is peeled off.

In addition to the above configuration, a stopper 30 is attached to the base 21, and the stopper 30 rotates integrally with the base 21 and contacts the governor 27 to move the governor 30 in the direction B. Restrict and cut 2
6, the amount of biting into the wire 3 can be regulated. Further, in the peeling cutter 20, the screw portion 31 formed on the stopper 30 is screwed into the male screw portion 32 formed on the base portion 21. As a result, the entire stopper 30 is oriented in a desired direction with respect to the base portion 21. The stop 30 can be moved in the direction of the arrow D or C by rotating in the direction of. Further, the stopper 30 is positioned on the base portion 21 by screwing the nut 33. Thereby, in the peeling cutter 20,
The position of the stopper 30 can be easily adjusted from outside the apparatus.

Actually, in the peeling cutter 20, the above-mentioned three arms 24 are arranged around the support member 22, and a contact portion of the stopper 30 is formed at a position facing the governor 27 of each arm 24. As a result, the peeling cutter 20 is brought into contact with the wire 3 from three directions of the wire 3 by the three cutters 26 to peel off the coating, and at the same time, the stopper 30 is slid in the direction of the arrow D or E so that each cutter 26 It is made possible to adjust the amount of bite of the body at a time.

In the above-described configuration, when the peeling cutter 20 rotates around the wire 3, the arm 24 is deflected counterclockwise by the centrifugal force generated in the governor 27. At this time, the stop position of the arm 24 is regulated according to the position of the stop 30 by the stop 30 contacting the governor 27 from the outer peripheral direction. That is, when the stopper 30 is moved in the direction of arrow D, the rotational position of the arm 24 is deviated counterclockwise around the fulcrum 25, and the amount of the bite 26 of the cutter 26 with respect to the wire 3 can be increased.

On the other hand, when the stopper 30 is moved in the direction of arrow E, the rotational position of the arm 24 is deviated clockwise about the fulcrum 25, so that the amount of the cutter 26 biting the wire 3 can be reduced. At this time, peeling cutter 2
At 0, the distance from the fulcrum 25 to the governor 27 is L
If the distance from the fulcrum 25 to the cutter 26 is L2, the ratio of the amount of rotation of the governor 27 to the amount of rotation of the cutter 26 is L1: L2.

In the case of the embodiment, L1: L2 = 2: 1 is selected, and the stopper 30 regulates the amount of rotation of the governor 27.
When the stopper 30 is moved in the direction D or E, the bite amount of the cutter 26 with respect to the wire 3 can be changed by about の of the movement amount.
In the conventional peeling cutter 1 shown in FIG. 3, the ratio of the amount of movement of the stopper 15 in the direction D or E to the amount of rotation of the cutter 13 is substantially L3: L4, and this value is selected to be 1: 2. As a result, the bite amount of the cutter 13 changes by almost twice the amount of movement of the stopper 15.

As described above, in the peeling cutter 20, the change of the bite amount of the cutter 26 with respect to the moving amount of the stopper 30 can be reduced to almost 1/4 of the conventional one. It is made possible to finely adjust the amount of bite into.

According to the above arrangement, the stopper 30 for regulating the turning position of the arm 24 and adjusting the bite amount of the cutter 26 with respect to the wire 3 is provided on the outer side surface of the base portion 21. Easy peeling cutter 2
0 can be realized. Further, a stopper 30 for regulating the rotation position of the arm 24 and adjusting the bite amount of the cutter 26 with respect to the wire 3 is disposed at a position facing the governor 27, and the stopper 30 abuts on the outer surface of the governor 27 to stop the arm 24. By controlling the rotation position, the release cutter 30 can finely adjust the amount of release of the coating material.
Can be realized.

In the embodiment described above, the female screw 3
1 and the external thread 32 are screwed together, and the stopper 30 is attached to the base 21 so as to be able to advance and retreat by the nut 33. However, the present invention is not limited to this. The stopper 30 may be positioned at a desired position by providing a penetrating screw hole and fitting a screw into the screw hole so that the stopper 30 is tightened to the base portion 21. What is necessary is just to be able to move forward and backward and to be able to position the stopper 30 at a desired position on the base 21.
