Description

[Detailed Description of the Invention] This invention relates to a wire turning device for rotating and scraping off the insulating jacket of a conductive wire, for example.

With conventional wire rod turning devices, the turning position of the wire rod cannot be changed without stopping the turning device during turning. Furthermore, while the turning device is stopped, the cutter is in contact with the wire, making it difficult to take the wire in and out of the turning device and to replace the cutter. Furthermore, it is difficult and dangerous to stop the turning device suddenly. This invention was made in order to eliminate the drawbacks of the conventional method, and it makes it possible to change the turning position of the wire rod even during turning, making it easier to take the wire in and out of the turning device and to change the cutter. This allows the device to be stopped suddenly. An embodiment of this invention will be described below with reference to the drawings.

The figure is a partially sectional front view showing an embodiment of the wire turning device according to the invention. In the figure, the rotating member 1 includes a hole 101 that is bored along the axis and into which the wire 2 is inserted, and a pair of notch grooves 102 and 103 that are provided opposite to each other at the outer end. The guide member 3 is inserted into the outer end of the hole 101, and the wire rod 2
It is provided with a hole 301 for guiding. The mounting base 4 rotatably mounts the rotating member 1 via a bearing receiving portion 5 and a bearing 6. Holder 7 is
A cylindrical body 7a through which the rotating member 1 is inserted, a pair of collar portions 701 provided at both ends of the cylindrical body 7a,
702, and a groove 703 formed by being surrounded by the outer circumferential surface of the cylindrical body 7a and the pair of collar portions 701, 702.
It has a spool-like structure. The guide member 8 is attached to the outer circumferential surface of the rotating member 1 along the axial direction, and is loosely fitted into a guide groove (not shown) provided along the axial direction on the inner circumferential surface of the cylindrical body 7a. 7a is slidably guided in the axial direction. A roller 11 is attached to one end of the pair of rotating arms 9, 9 by a pin 10, respectively, and the roller 11 is slidably inserted into a groove 703 of the holder 7. The other ends of the pair of rotating arms 9, 9 are rotatably attached to a fixed arm 13 by pins 12, respectively, and the fixed arm 13 is attached to the mounting base 4. The turret 14 has a notch groove 1
02, and the inner end shaft center side is the pin 15.
It is rotatably attached to the rotating member 1 by. The cutter 16 is attached to the outer end of the tool rest 16 and the tool rest 14 by an adjustment screw 17, and the blade part 1
61 is attached to the wire rod 2 at the adjustment screw 1
7 makes it adjustable. Tightening screw 18
The blade 16 is attached to the adjustment screw 17. The pedestal support part 19 is inserted into the notch groove 103, and the pedestal 21 is rotatably attached to the rotating member 1 by a pin 20 on the axis side of the inner end.
is attached to the outer end of the pedestal support part 19 with an adjustment screw 22, and the end surface on the axis side is provided with a triangular groove 211 into which the wire rod 2 is inserted.
The mounting position of 11 with respect to the wire rod 2 is the adjustment screw 2.
It is made adjustable by 2. Tightening screw 23
is for attaching the pedestal 21 to the adjustment screw 22. The connecting members 24a and 24b are connected to the holder 7, the tool rest 14, and the cradle support part 1 by means of pins 25 and 26.
It is rotatably mounted between 9. The electromagnetic clutch 27 connects the rotating member 1 and the rotating shaft 28 of the electric motor, and is composed of the following members. A fixed iron core 271 is attached to a rotating shaft 28, and an electromagnetic coil 272 is wound around it. The fixed member 273 is attached to the rotating member 1. The movable core 274 is slidably supported within a groove 275 provided in the fixed member 273, and when the electromagnetic coil 272 is energized, the spring 2
76 and is attracted to the fixed iron core 271. The housing 277 has bearings 278, 27
9 is attached to the rotating member 1 and the rotating shaft 28, and covers each component of the electromagnetic clutch 27.

Next, this operation will be explained. Hole 10 of rotating member 1
1 through the hole 301 of the guide member 3, and cut the portion of the wire 2 whose insulating jacket is turned using the cutter 1.
Adjust to position 6. Next, the blade part 161 of the knife 16
After adjusting the mounting position of the triangular groove 211 of the pedestal 21 with respect to the wire rod 2 with the adjusting screws 17 and 22, the screws are fixed with the tightening screws 18 and 23. Thereafter, the electromagnetic coil 272 is excited, the movable iron core 274 is attracted to the fixed iron core 271, and the rotating member 1 is moved to the rotating shaft 2.
8 and rotated, centrifugal force causes the tool rest 14 and the pedestal support part 19 to move against the pins 15 and 20, respectively.
The blade part 161 of the knife 16 and the pedestal 21
The triangular groove 211 rotates in the direction away from the wire 2. In this state, when the rotating arm 9 is rotated clockwise around the pin 12 by an arm rotating device (not shown), the holder 7 slides to the left of the rotating member 1 along the guide member 8. Moving.
The tool rest 14 and the cradle support part 19 are connected by a connecting member 24
Since they are connected to the holder 7 via the pins 15 and 24b, the tool rest 14 and the cradle support 19 are centered around the pins 15 and 20, respectively, and the blade part 161 of the cutter 16 is
and the triangular groove 211 of the pedestal 21 rotate in the direction in which they contact the wire 2 . Blade portion 161 and triangular groove 21
1 comes into contact with the wire rod 2 as shown in the figure, the rotating arm 9 stops rotating. In this way, wire rod 2
The insulating jacket is turned.

Next, a case will be described in which the turning position of the wire rod 2 is changed during turning. When the rotating arm 9 is rotated counterclockwise about the pin 12 while the rotating member 1 is rotating, the holder 7 slides along the guide member 8 to the right of the rotating member 1. Since the tool rest 14 and the cradle support part 19 are connected to the holder 7 via the connecting members 24a and 24b, respectively, the tool rest 14 and the cradle support part 19 are centered around the pins 15 and 20, respectively. The blade portion 161 and the triangular groove 211 of the pedestal 21 rotate in the direction away from the wire 2. In this state, the wire rod 2 is slid within the hole 101 to change the turning position. Furthermore, even if the rotation of the rotating member 1 is stopped in this state, the tool rest 14 and the pedestal support part 19 stably maintain a state apart from the wire rod 2, so that they can be moved in and out of the hole 101 of the wire rod 2. In addition, the blade 16 can be easily replaced. Furthermore, in an emergency or an emergency, by cutting off the power to the electromagnetic coil 272 of the electromagnetic clutch 27, the connection between the rotating member 1 and the rotating shaft 28 is cut, and the rotating member 1 is stopped urgently. can quickly deal with the situation.

As described above, according to this invention, the turning position of the wire rod can be changed without stopping the turning device during turning of the wire rod due to the simple structure, and the turning position of the wire rod can be changed in and out of the turning device and the cutting tool can be changed. can be easily replaced. Furthermore, since it is equipped with an electromagnetic clutch, it has various effects such as being able to quickly respond to emergencies.
