Description

  The present invention relates to an electric wire processing apparatus and an electric wire processing method for stripping off an insulation coating at a longitudinal end portion or an intermediate portion of an electric wire.

  2. Description of the Related Art Conventionally, an electric wire processing device (peeling device) that strips an insulation coating to connect a core wire to a terminal fitting or the like at a longitudinal end portion of a covered electric wire with an insulation coating on the core wire is used (for example, Patent Document 1). reference). Such an electric wire processing apparatus grips the electric wire sent out in the longitudinal direction by a clamp at a predetermined position, and cuts in the circumferential direction of the insulation coating by a pair of cutters sandwiching the longitudinal end portion of the electric wire from both sides.

Japanese Patent Laid-Open No. 10-12350

  However, in the electric wire processing apparatus as shown in Patent Document 1 described above, the insulation coating cut in the circumferential direction is pulled out from the core wire by the slide of the cutter. When the length of the insulating coating is long, the frictional resistance with the core wire is increased, so that it is difficult to pull out the insulating coating. Further, since the cutter with the cut is slid along the core line, if the cut depth of the cutter is too large, the cutter blade may be rubbed and scratch the core line. The electric wire may be an unshielded electric wire with one or more core wires covered with an insulating coating, or a shielded electric wire with one or more core wires covered with a shield braid and covered with an insulating coating. In the case of a shielded electric wire, there is a concern about damage to the shield braid as well as damage to the core wire as described above.

  For the above reasons, in order to adjust the cutting depth of the cutter, an operator may perform adjustment work in the vicinity of the cutter and the electric wire. In this case, the operator's hand or tool touches the cutter blade. There is a possibility that. In addition, instead of the process of pulling out the insulation coating from the core wire or the core wire covered with the shield braid by sliding between the cutter and the electric wire by automatic operation, the step of stripping the insulation coating is performed by manual operation of the operator. It is also conceivable to suppress damage to the shield braid. When performing such manual operation, it is necessary to prevent the operator's hand or tool from being caught in the device when gripping the electric wire with a clamp or cutting the insulation coating with a cutter. is there. However, in the conventional electric wire processing apparatus premised on automatic operation, it is not assumed that manual operation or manual adjustment is performed, so that countermeasures are not sufficient. Even when the insulation coating is stripped off by automatic operation, it is effective to take similar measures to adjust the cutting depth, and the development of such a processing device is desired. It was.

  In view of the above points, the present invention can easily cope with various types of electric wires regardless of manual operation and automatic operation, and cuts the insulation coating while preventing damage to the core wire and the shield braid.

In this case, the movement of the cutting cutter is regulated, and the regulation of the cutting cutter is released when the guide member moves to the guide position.

  With the above configuration, when the guide member is at the retracted position, the movement of the cutting cutter is restricted, and the movement restriction of the cutting cutter is released by moving the guide member to the guide position. It is possible to prevent an operator's hand or tool from being caught unintentionally when setting. Furthermore, by covering the gap between the pair of electric wire clamps and the blade of the cutting cutter with the guide member moved to the guide position, the operator's hand or tool when manually operating can be protected with the guide member, Adjustment work can be performed in a safe state even in the case of automatic operation. Therefore, while setting the electric wire between the electric wire clamps and between the cutting cutters, the guide member is moved to the guide position after performing necessary work for each electric wire in the state where the guide member is located at the retracted position. Thus, the cutting cutter whose movement restriction is released can be moved in the approaching direction by the operating means, whereby the pair of cutting cutters can be bitten into the insulating coating.

The electric wire 90 is pushed into the holding groove 23 along the extending portion 24 of the fixed side clamp 21, and the electric wire 90 is gripped by the fixed side clamp 21 and the moving side clamp 22. Further, the abutting plate 26B moves together with the moving side clamp 22, and pushes the push button 73 so that the locking pin 74 is retracted, and the locking of the guide member 50 by the locking means 70 is released, whereby the coil spring 55 is attached. The guide member 50 is retracted to the retracted position by the force.

  Thus, in the holding state where the electric wire 90 is held between the fixed side clamp 21 and the moving side clamp 22, as shown in FIG. 11, the first cutter 31 and the second cutter 32 abut each other, and each blade The electric wire 90 is sandwiched between the portions 33 and 34, and the blade portions 33 and 34 bite into the insulating coating 91. Then, the guide member 50 is retracted to the retracted position, and the moving cover 26 is moved to the back side of the fixed-side clamp 21, so that the end portion side of the electric wire 90 sandwiched between the blade portions 33 and 34 is exposed.

  In the above holding state, the operator inserts a finger or a tool into a notch formed in advance along the longitudinal direction of the electric wire 90, and pulls the edge of the insulating covering 91 along the notch, thereby insulating the insulating cover 91. Is cut in the circumferential direction along the blade portions 33, 34, and the insulation coating 91 is peeled off to expose the core wire 92 and the shield braid at the end of the electric wire 90. Further, even if the notch is not formed in advance along the longitudinal direction of the electric wire 90, the blade portions 33 and 34 of the first cutter 31 and the second cutter 32 are deeply cut into the insulating coating 91, or the insulating coating 91. Can be removed by sliding relative to the core wire 92 and the shield braid. When the insulating coating 91 at the end of the electric wire 90 is removed as described above, the operating lever 45 of the operating means 40 is rotated to the side away from the electric wire clamp 20 and the moving side clamp 22 is separated from the fixed side clamp 21. After the second cutter 32 is separated from the first cutter 31, the processed electric wire 90 in which the core wire 92 and the shield braid at the end are exposed is taken out from the electric wire processing apparatus 1 and the processing is completed.

  According to this embodiment, when the guide member 50 is in the retracted position, the movement of the moving side clamp 22 and the second cutter 32 is restricted by the restricting means 60, and the guide member 50 is moved to the guide position. The restriction of the restricting means 60 is removed and the movement side clamp 22 and the second cutter 32 are allowed to move. In addition, it is possible to prevent an operator's hand or tool from being caught unintentionally when setting the electric wire 90 between the electric wire clamps 20, and the electric wire clamp 20 is moved by the guide member 50 moved to the guide position. By covering the gap and the first cutter 31 and the second cutter 32, it is possible to protect the hands and tools of the manually operated operator. Therefore, in a state where the movement of the moving side clamp 22 and the second cutter 32 is restricted by the restricting means 60, the necessary work is performed for each of the various electric wires 90, and then the guide member 50 is moved to the guide position to restrict the movement. Can be released, and the work of adjusting the biting depth of the blade portions 33 and 34 corresponding to various electric wires 90 can be easily performed, and the core wire 92 and the shield braid can be reliably prevented from being damaged. The insulating coating 91 can be stripped off.

  Further, in a state where the moving side clamp 22 and the second cutter 32 are separated from the fixed side clamp 21 and the first cutter 31, the first cutter 31 is covered with the moving cover 26 and the second cutter 32 is covered with the fixed cover 27. The operator's hand or tool can be prevented from coming into contact with the blade portions 33 and 34 of the cutting cutter 30. On the other hand, the moving side clamp 22 and the second cutter 32 are moved so that the electric wire 90 is gripped by the fixed side clamp 21 and the moving side clamp 22, and between the blade portions 33, 34 of the first cutter 31 and the second cutter 32. When the guide member 50 and the moving cover 26 are moved in a state where the electric wire 90 is sandwiched, the electric wire 90 in which the blade portions 33 and 34 have bite can be exposed, and the insulation coating 91 is easily stripped off. can do.

  In addition, although the said embodiment demonstrated the electric wire processing apparatus 1 for stripping off the insulation coating 91 of the electric wire 90 which has the two core wires 92, the electric wire which the electric wire processing apparatus of this invention makes object is the said implementation. Not only the form but also an electric wire having one core wire or an electric wire having three or more core wires may be used. At this time, it is only necessary to prepare a cutting cutter having an appropriately shaped blade according to the cross-sectional shape of the electric wire, and accordingly, the shape of the electric wire clamp may be appropriately changed.

  Moreover, in the said embodiment, although the case where the insulating coating 91 in the edge part of the electric wire 90 was stripped off was illustrated, it is also possible to strip off the insulating coating in the intermediate part of an electric wire using the electric wire processing apparatus of this invention. That is, when cuts along the longitudinal direction are formed in a range of a predetermined length in the middle part of the electric wire, at both ends of the cuts, respectively, along the circumferential direction as described in the above embodiment. What is necessary is just to cut | disconnect an insulation coating and strip off the insulation coating in the meantime. As described above, even when the cutting operation is performed twice on one electric wire 90, the positioning and position adjustment of the electric wire 90 at each operation can be safely performed.

  In the embodiment, the electric wire 90 is set between the pair of electric wire clamps 20 and the pair of cutting cutters 30, is moved apart and moved by the operating means 40 of the moving side clamp 22 and the first cutter 31, and further, the electric wire 90. Although the case where each process of peeling of the insulation coating 91 in the holding state is performed by an operator's manual operation has been described, the electric wire processing apparatus may include a driving device that automatically executes each process. Even in the case of such automatic operation, the electric wire 90 can be set, positioned, and adjusted in a safe state.

  Furthermore, in the said embodiment, although the cut | disconnection along the longitudinal direction of the electric wire 90 was cut | disconnected along the circumferential direction from the state by which the insulation coating 91 was previously formed, The cut in the longitudinal direction may be formed after cutting, or the cutting in the circumferential direction and the cutting in the longitudinal direction may be continuously performed by the electric wire processing apparatus of the present invention.

  The electric wire processing apparatus and electric wire processing method according to the present invention can be used as a peeling apparatus and method for peeling off the insulation coating at the longitudinal ends and intermediate portions of various electric wires.
