Description of the Related Art In an electric wire processing machine 21 for crimping a terminal to an end portion of an electric wire, as shown in FIGS. 6 to 8, an electric wire W sent by a feeding roller 22 to a predetermined length is fed from a grip 24 to an upstream side. After being cut by the cutter 23 with the cantilevered length L protruding to the above, the cut electric wire W is gripped by a pair of grips 24 that can be opened and closed in the vertical direction and sent to a strip process (not shown).

In the stripping process, the coating of the end portion (cut end) E of the electric wire W is stripped off, and the strip sensor 25 detects whether or not the strip processing is completed.

Then, the electric wire W moves laterally X of the grip 24.
After being sent to the crimping machine 26 in the terminal crimping step, the crimping machine 26 crimps the terminal T to the end portion of the electric wire W.

As described above, in the electric wire processing machine 21 in which the grip 24 is arranged to grip the electric wire W on the downstream side in the electric wire feeding direction Y, when the grip 24 moves laterally X to the crimping machine 26 side. In order to prevent the interference with the crimping machine 26, the cantilever length L of the electric wire W is made longer to some extent.

The steady rest 2 is made of an elastic material such as rubber or synthetic resin, has a flat gripping surface F2, and has a lateral eave protruding toward the upstream side in the wire feeding direction Y (that is, the crimping machine 26 side). It is composed of a portion 2a and a mounting portion 2b extending vertically from the base end portion of the eaves portion 2a.

The holding metal fitting 3 is made of a steel plate or the like and has an L-shaped cross section. The holding metal fitting 3 comprises a vertical holding portion 3a and a fixing portion 3b extending laterally from the base end of the holding portion 3a. The portion 3a is provided with a cutout portion N in an arc shape so that the restraining portion 3a does not interfere with the base end portion of the eaves portion 2a.
An elongated hole 3c into which the set screw 4 can be inserted is provided in b.

A head bolt is applied to the set screw 4.

The steadying member 2 is mounted such that the facing surface F2 of the steadying member 2 is flush with the facing surface F1 of the grip 24. Instead of this, as shown in FIG.
The facing surface F2 of the steady rest 2 is replaced with the facing surface F of the grip 24.

The wire gripping device of the wire processing machine according to the present invention comprises a feed roller for feeding the wire to a predetermined length, a cutter for cutting the wire, and a grip for gripping the cut wire. An electric wire processing machine in which the grip is arranged on the downstream side in the electric wire feeding direction, and a pair of steady rest members made of elastic material are detachably attached to the grip on the upstream side in the electric wire feeding direction. Therefore, the runout of the electric wire end portion during the electric wire transportation becomes extremely small as compared with the case where the electric wire is gripped only by the conventional grip.

Therefore, the detection function of the strip sensor is stabilized, and the positional displacement of the terminal crimp is eliminated, so that the productivity is remarkably improved.

Further, since the steady rest that is attached so as to project to the crimping machine side is made of an elastic material, there is no risk of damage even if it interferes with the crimping machine due to an erroneous operation or the like, so equipment reliability is greatly improved. It has excellent advantages such as being improved.
