【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The crimping pliers 1 include a pair of arms 3 and 3A whose distal ends are rotatably connected via pivots 2 and whose base ends are openable and closable, and support shafts respectively attached to the distal ends of the pair of arms 3 and 3A. A pair of crimping claws 5, 5A rotatably attached via a support plate 7, and a supporting plate 7 attached to the center of each crimping claw 5, 5A via support pins 6, 6A. And a spring member (not shown) which is wound around the pivot 2 and whose end extends inside the arms 3 and 3A, and which constantly urges the arms 3 and 3A to open. is there.

The machine frame 11 in which the crimping pliers 1 are set is formed with a window hole 12 through which the crimping claw portions 5 and 5A are projected in the lateral direction. Inside the window hole 12, the pivot shaft 2 is formed. The first and second bearing portions 13 and 13A for supporting the bearing are provided at two places. The bearings 13 and 13A are provided in the central axis X direction of the window hole 12, and the pivot 2 is selectively attached to either one of them. The first bearing portion 13 is attached to the rear side of the window hole 12 provided in the machine frame 11 and is provided with a pair of left and right attachment bodies 15 and 15A provided on both sides of the pivot shaft 2, and the attachment on the-side. Main body attachment A first concave portion 16 provided inside the main body 15, 15A, which is a first receiving portion into which one end 2A of the pivot shaft 2 can be fitted, and a first concave portion 16 facing the first concave portion 16 on the other side. The screw rod 18 screwed into the female screw hole 17 provided in the mounting body 15A, and the second receiving portion which is provided at the tip of the screw rod 18 and into which the other end 2B of the pivot 2 can be fitted. And a concave portion 19 thereof. The second bearing portion 13A is similarly provided on the mounting bodies 15 and 15A. Reference numeral 14 is an opening / closing plate attached to the machine frame 11.

Upper and lower rollers 20 and 20A, which are pressing members for pressing the arms 3 and 3A, are provided substantially in the center of the machine frame 11. The peripheral surface of the upper roller 20 contacts the upper surface of the arm 3, while the peripheral surface of the lower roller 20A contacts the lower surface of the arm 3A. The rollers 20 and 20A can be moved up and down by a vertical movement driving device 21. The vertical motion drive device 21 includes a motor 22, an upwardly facing upper rack 24 that meshes with a drive gear 23 connected to a rotation shaft of the motor 22, and a top roller 24 that is fixed to the upper rack 24 and rotates the upper roller 20. The upper lifting member 25 is movably supported, and the lower lifting member 25A is fixed to the lower rack 24A and rotatably supports the lower roller 20A. Reference numerals 26 and 26A in the drawing denote upper and lower guide members for guiding the upper and lower elevating members 25 and 25A, respectively, by sliding them upward and downward.

Upper and lower position detection sensors 27, 27A, which are limit switches, are disposed above and below the lower guide member 26A, and when the lower elevating member 25A is moved up or down, either one of the detection sensors 27 is detected. , 27A is activated. Further, the diameter of the hole 28 of the upper roller 20 is formed larger than the mounting shaft 29 provided in the upper elevating member 25, and is attached so that it can be slightly elevated. An arm detection sensor 30 of the crimping pliers 1 composed of a limit switch is provided above the upper elevating member 25 integrally with the upper elevating member 25, and the detecting portion 30A of the detecting sensor 30 is arranged downward. There is.

In the figure, 31 is a power switch, 32 is a counter showing the number of times of crimping, 33 is a changeover switch that makes a fine movement and a state in which the crimping operation is stopped every cycle, and 34 is for performing the crimping operation continuously. It is a continuous switch. Further, 35 is a foot switch, and 36 is a switch attached to the opening / closing plate 14.

Next, the operation of the above configuration will be described. When the crimping pliers 1 are set, the opening / closing plate 14 is opened, the crimping pliers 1 are inserted, and the crimping claw portions 5 and 5A are projected from the window hole 12 from the inside. Next, the − side of the pivot 2 is fitted into the first recess 16 of the first bearing portion 13, and the screw rod 18 provided in the female screw hole 17 is rotated to rotate the second side formed at the tip thereof. The recess 19 is fitted to the other side of the pivot 2. At the same time, the upper roller 20 is set on the lower surface of the arm 3 and the lower roller 20A is set on the upper surface of the arm 3A. At this time, if the power switch 31 is turned on in advance and the crimping pliers 1 are properly set, the arm 3 is urged by the spring member provided in the crimping pliers 1, and the roller 20 slightly rises with respect to the mounting shaft 29, and the detecting portion 30A. Is activated, and as a result, the arm detection sensor 30 can detect that the crimping pliers 1 are correctly set. If the crimping pliers 1 are not set correctly without the detection unit 30A operating, the crimping operation cannot be performed.

If the pivot shaft 2 cannot be set in the first bearing portion 13 depending on the type of the crimping pliers 1, the pivot shaft 2X of the crimping pliers 1X is connected to the second bearing portion as shown by the chain double-dashed line in FIG. The first bearing portion 13 may be set in 13A.

Next, when the continuous switch 34 is turned on, the motor 22 rotates counterclockwise and the upper roller 20 descends via the drive gear 23, the upper rack 24, and the upper elevating member 25. The lower roller 20A ascends via the lower rack 24A and the lower elevating member 25A. As a result, the arms 3 and 3A are narrowed in the included angle against the spring member, and the crimp claws 5 and 5A are narrowed, so that the cable ( The terminal crimping work (not shown) can be performed. When the lower position detecting sensor 27A is operated by the lower lifting member 25A, the motor 22 is switched and the motor 22 rotates clockwise. Due to this rotation, the upper roller 20 is raised, while the lower roller 20A is lowered. Therefore, the spring member expands the included angle of the arms 3 and 3A, and as a result, the crimp claw portions 5 and 5A expand and the cable (not shown) that has been crimped is removed, and a new cable (not shown) is re-installed. Set with terminals (not shown). When the lower lifting member 25A moves upward, the upper position detection sensor 27 operates to rotate the motor 22 counterclockwise.

When the change-over switch 33 is stopped every cycle, the foot switch 35 or the switch 36 can be operated to stop the crimping operation every cycle. On the other hand, when the changeover switch 33 is set in a state of fine movement, the pressure switch can be finely moved by operating the foot switch 35 or the switch 36.
