  However, the assembly jigs of Patent Documents 2 and 3 described above have problems that they cannot be moved in all directions of XYZ or that the structure is complicated and expensive.

  An object of the present invention is to provide a general-purpose wire harness assembling jig having the functionality that can solve the above-described problems and can be adapted to various uses.

  The technical characteristics of the wire harness assembling jig according to the present invention for achieving the above-described object include a base fixed on a harness assembly plate, and an X that can slide on the base in the horizontal X-axis direction. A shaft sliding member, a Y-axis sliding member that is fitted to the X-axis sliding member and is slidable in a horizontal Y-axis direction orthogonal to the X-axis, and a screw in the Z-axis direction with respect to the Y-axis sliding member A Z-axis member that includes a mating shaft portion and can be moved up and down by screwing the shaft portion, and an electric wire support portion fixed to the upper end of the Z-axis member.

  According to the wire harness assembling jig according to the present invention, the electric wire support portion can be arranged at an arbitrary position and direction.

The present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 shows a perspective view of a wire harness assembling jig according to an embodiment. A dovetail groove 13 having an opening 12 is formed on a strip-like base 11 in the longitudinal horizontal direction that is the X axis. Moreover, the cavity part 15 which has the opening 14 toward the side is formed in the both sides of the base 11 along a longitudinal direction. In addition, fixing holes 16 for fixing the base 11 to the harness assembly plate are drilled at a plurality of locations on the base 11.

  As shown in FIGS. 2 and 3, a block-shaped X-axis sliding member 21 is arranged on the base 11, and the side of the X-axis sliding member 21 is bent to the side of the base 11, and the opening 14 A side plate 22 reaching the upper end is formed. In the dovetail groove 13, two nuts 23 matching the shape of the dovetail groove 13 are inserted, and two bolts 24 inserted from the upper surface of the X-axis sliding member 21 through the opening 12 are connected to the dovetail groove 13. The X-axis sliding member 21 is screwed into the nut 23 so that the X-axis sliding member 21 does not come off from the base 11. The side plate 22 also serves as a guide member when the X-axis sliding member 21 moves in the X-axis direction indicated by a one-dot chain line.

  The X-axis sliding member 21 can be fixed at any position in the X-axis direction of the base 11 by a bolt 25 on the side plate 22 side. That is, a nut 26 is inserted into the cavity 15 on the side of the base 11, and the bolt 25 is screwed into the nut 26 from the outside via the side plate 22, the L-shaped plate 27, and the washer 28. ing. The L-shaped plate 27, the side plate 22, and the side portion of the opening 14 of the hollow portion 15 are sandwiched by bolts 25 and nuts 26, and the X-axis sliding member 21 is fixed to the base 11.

  4, the X-axis sliding member 21 has a guide groove 29 formed in the Y-axis direction. The Y-axis sliding member 31 has a plate-like bottom 32 fitted in the guide groove 29. The X-axis sliding member 21 is movable along the guide groove 29 in the Y-axis direction. By tightening the bolt 24, the bottom 32 of the Y-axis sliding member 31 can be attracted and fixed to the X-axis sliding member 21 at an arbitrary position in the Y-axis direction, and the X-axis sliding The moving member 21 is fixed to the base 11.

  As described above, the X-axis sliding member 21 is provided with two fixing bolts 24 and 25, and the bolt 25 locks the sliding of the X-axis sliding member 21 only in the X-axis direction. The Y-axis sliding member 31 is fixed in the Y-axis direction and the X-axis sliding member 21 is fixed in the X-axis direction. In use, the X-axis sliding member 21 is temporarily fixed with the bolt 25 in the X-axis direction, and then the X-axis sliding member 21 and the Y-axis sliding member 31 are simultaneously permanently fixed with the bolt 24. When adjusting the sliding member 31, it is possible to prevent the positional deviation in the X-axis direction from occurring.

  Further, a screw hole 33 is formed on the Y-axis sliding member 31 in the Z-axis direction, and the screw shaft 42 of the Z-axis moving member 41 is screwed into the screw hole 33. An electric wire support 44 having a U-shaped member 43 is fixed to the upper end of the screw shaft 42 as shown in FIG. In addition to the U-shaped member 43, the electric wire support portion 44 can be arbitrarily selected and attached with a jig such as a fixing clip in accordance with the purpose of electric wire support. A nut 45 and a washer 46 are attached to the screw shaft 42, and after adjusting the height of the wire support portion 44, the nut 45 is tightened so that the screw shaft 42 is positioned at the position relative to the Y-axis sliding member 31. It can be fixed.

  As shown in FIG. 5, the fixing member 51 that fixes the base 11 in the shape of a harness assembly plate is divided into an upper half 52 and a lower half 53, and the upper half 52 and the lower half 53 are connected via a shaft 54. Can be rotated. This rotation is such that the upper half 52 can be rotated 90 degrees with respect to the lower half 53 by a steel ball 56 and a spring 57 fixed by a bolt 55. The bolt 55 is fixed by a nut 58 and a washer 59.

  Bolts 60 are fixed upward in the upper half 52 and are inserted into the fixing holes 16 of the base 11 from below and can be fixed to the base 11 using nuts 61. The lower half 53 has a bolt 62 fixed downward. The lower half 53 is inserted into a hole provided in the harness assembly plate, and a nut is screwed into the bolt 62 from the back side of the assembly plate. 53 can be fixed to the assembly plate.

  The X-axis sliding member 21 is moved and fixed at a desired position with respect to the base 11, and the Y-axis sliding member 31 is further moved and fixed along the guide groove 29. Further, by rotating the screw shaft 42 with respect to the screw hole 33 of the Y-axis sliding member 31, the height of the wire support portion 44 at the upper end of the screw shaft 42 is adjusted. Furthermore, the direction can be adjusted by fixing the screw shaft 42 with the nut 45 with the electric wire support portion 55 directed in an arbitrary direction.

  The base 11 adjusted in this way is fixed on the harness assembly board using a plurality of fixing members 51. In this fixed state, the base 11 is provided at a predetermined height position from the surface of the assembly plate, and the electric wire bundle can be hung on the U-shaped member 43 on the assembly plate.

  When the fixed base 11 is not used, as shown in FIG. 6, the base 11 is harness-assembled by rotating the upper half 52 about the shaft 54 with respect to the lower half 53 by 90 degrees. Can be laid down on the board.
