  After that, by moving the predetermined distance in any direction orthogonal to the wire supply direction Q, one end of the adjustment operation rod 125 strikes the stopper portion 128 on the selected side, and in this state further in that direction By moving the predetermined distance, the movable nozzle guide 123 is slid relatively in the opposite direction, and the notch portion 123a of the movable nozzle guide 123 and the arcuate wire receiving portion 122c of the fixed nozzle guide 122 are operated to approach or The nozzle opening 130 is adjusted so as to have an optimum size.

  When the selected stopper portion 128 and the adjustment operation rod 125 are hit, information on the previous wire diameter is stored in a memory or the like, and the current wire diameter is larger than the previous wire diameter. Is adjusted by striking in the direction in which the nozzle opening 130 is expanded. If the current wire diameter is smaller than the previous wire diameter, the movement is adjusted by striking in the direction in which the nozzle opening 130 is narrowed. Control may be used.

  On the other hand, once the adjustment operation rod 125 is hit against the stopper portion 128 in the direction of opening the nozzle opening 130 and released, the adjustment operation rod 125 is hit against the other stopper portion 128 and then the nozzle opening 130 is opened. It is good also as movement control which adjusts to the optimal magnitude | size.

  After the nozzle opening 130 is adjusted, the moving base 109a returns to the initial position, and the above-described processing is repeated.

  Therefore, even if the wire diameter of the wire 102 to be used is changed, the size of the nozzle opening 130 in the wire nozzle portion 117 is changed to the outside of the wire 102 by the sliding operation of the movable nozzle guide 123 by the opening adjustment movement of the moving base 109a. Since it is automatically adjusted to the size according to the diameter, it is not necessary to replace parts such as conventional nozzles, and it is not necessary to prepare and store multiple types of nozzles, and the work time for setup changeover There is an advantage that can be shortened.

  In addition, the movement of the moving base 109a is used to adjust the size of the nozzle opening 130 in the wire nozzle portion 117, so that the member can be shared and the adjustment operation rod 125 for adjusting the nozzle opening 130, the stopper portion 128, etc. There is an advantage that the structure of the interlocking device can be simplified.

  Further, the adjustment operation rod 125 is connected to the movable nozzle guide 123 of the wire nozzle portion 117, and one end of the adjustment operation rod 125 is selected by hitting either one of the stopper portions 128 erected on the mount 113. Therefore, the movable nozzle guide 123 can be slid to adjust the size of the nozzle opening 130, and can be easily provided by a slight design change using the conventional both-end terminal crimping device 101 and provided at low cost. it can.

  Further, it is only necessary to connect the adjustment operation rod 125 to the movable nozzle guide 123 of the wire nozzle portion 117 provided in the moving table 109a, and the increase in moving weight of the moving table 109a as a whole can be effectively suppressed, and the moving load increases. Can also be effectively suppressed.

  Furthermore, since each stopper portion 128 is disposed at a position that avoids the movement trajectory during processing of the normal electric wire 102, the movement control of the moving base 109a during the processing of the electric wire 102 is not obstructed, and There will be no hindrance during processing.

  Moreover, since the notch 123a in the movable nozzle guide 123 is formed in a V shape, there is an advantage that the electric wire 102 inserted and guided by the nozzle opening 130 can be held in a stable posture.

  Further, inadvertent slide movement of the movable nozzle guide 123 can be effectively restricted by the urging force of each push spring 127 accommodated in each spring holding hole 123b, and the movable nozzle guide 123 due to vibration during movement of the movable table 109a or the like. Can be effectively prevented.

  In the above embodiment, a structure is shown in which the movable nozzle guide 123 is slid by one end of the adjustment operating rod 125 hitting the stopper portion 128 by moving the moving base 109a in a direction orthogonal to the electric wire supply direction Q. However, if the movable table 109a has a structure capable of three-dimensional movement control, the movable nozzle guide 123 may be slid by the vertical movement control of the movable table 109a. The position is not limited to the position shown in the embodiment, and may be arranged at a position that does not hinder normal processing operations.

  Moreover, although the control system which adjusts the nozzle opening 130 with the electric wire 102 information in the input process data is shown, the nozzle opening 130 is input according to the data by separately inputting the electric wire diameter of the electric wire 102 from the data input means. It may be a control method that adjusts.

  Further, the interlocking device that adjusts the size of the nozzle opening 130 is not limited to the structure of the above embodiment, and any device that adjusts the size of the nozzle opening 130 may be used.

  Moreover, in each said embodiment, although the structure employ | adopted as the both-ends terminal crimping apparatus 1 and 101 is shown as an example of an electric wire processing machine, the apparatus which processes the other electric wires 2 and 102 may be sufficient, and each said implementation There is no limitation on the form.
