 The previously proposed device for cutting a chain-like pin of this type is configured as shown in FIG.

That is, in FIG. 3, a pair of guide rods b are juxtaposed on the compatible ascending piece a1 of the frame body a having a channel-shaped cross section, and a pair of cutter slides are provided on both guide rods b. The moving bodies c and d are fitted so as to face each other. Further, the cutters e and f are attached to the cutter sliding bodies c and d so as to face each other, and the cutters e and f are chains to be inserted pins used as connector insertion pins. The pin W is cut. Further, a pair of cylinder devices g, h are horizontally installed on the compatible ascending piece a1 of the frame a so as to face each other and operate synchronously. The output shafts of the cylinder devices g, h The g1 and h1 are connected to the cutter sliding bodies c and d by the pin axes i and j.

Therefore, the chain pin cutting device described above operates the cylinder devices g and h at the same time to move the output shafts g1 and h1 of the cylinder devices inward toward each other to move the respective output shafts g1 and h1 inward. The cutter slide bodies c and d connected to the output shafts g1 and h1 are moved inward toward each other, whereby the cutters e and f attached to the cutter slide bodies c and d are inserted. The chain pin W that serves as a landing pin is cut into a predetermined length.

On the other hand, when the chain pin W, which is the inserted pin, is cut off, both of the cylinder devices g and h simultaneously return, and their output shafts g1 and h1 return to each other outwardly. By doing so, the cutter sliding bodies c, d connected to the output shafts g1, h1 are returned to the original position by returning to the outside.

On the other hand, another chain-type pin cutting device of this type that has been already proposed is configured as shown in FIG.

That is, in FIG. 4, a pair of guide rods b are juxtaposed on the compatible ascending piece a1 of the frame a having a channel-shaped cross section, and a pair of cutter slides are provided on both guide rods b. The moving bodies c and d are fitted so as to face each other. Further, the cutters e and f are attached to the cutter sliding bodies c and d so as to face each other, and the cutters e and f are chains to be inserted pins used as connector insertion pins. The pin W is cut into a predetermined length. Further, a cylinder device h is installed horizontally on one of the rising pieces a1 of the frame body a so that the output shaft h1 of the cylinder device h is on the one cutter slide body d and the pin shaft j. Are connected by. Further, an angled rack member k is vertically provided on the one cutter slide body d, and a rack k1 is horizontally engraved on a horizontal portion of the rack member k. A pinion m is rotatably mounted on a frame A which is integral with the frame a on which the rack k1 is located, and the pinion m meshes with the rack k1. Further, by horizontally reciprocating the rack k1, the pinion m meshing with the rack k1 is reciprocally rotated. A rack member n having a substantially L-shape is vertically provided on the other cutter sliding body c, and a rack n1 is horizontally engraved on a horizontal portion of the rack member n. . Further, the pinion m is meshed with the rack n 1, and when the rack k 1 moves inward, the rack k 1 pivots the pinion m meshed with the rack k 1 in the forward direction. The meshing rack n1 is moved inward.

[0008] Therefore, the chain pin cutting device described above operates the cylinder device h to move the output shaft h1 inward to move the cutter shaft connected to the output shaft h1. When the moving body d is moved inward, and the rack k1 of the rack member k suspended from the cutter slide body d is also moved inward, the rack k1 rotates the pinion m meshing with it. Since it moves, the rack n1 meshing with the pinion m is moved inward, and the cutter sliding body c integrated with the rack member n of the rack n1 is also moved inward.

As a result, both cutters e and f attached to the cutter sliding bodies c and d cut the chain pin W, which serves as the inserted pin, to a predetermined length.

On the other hand, when the cutting operation of the chain pin W which is the inserted pin is completed, the cylinder device h is returned and the output shaft h 1 thereof is returned to the outside, so that the output shaft h 1 Since the rack k1 of the rack member k that is integral with the cutter sliding body d connected to the backrest is outwardly returned, the rack k1 reversely rotates the pinion m that meshes with the rack k1. The rack n1 meshing with m is returned to the outside, and the cutter sliding body c integral with the rack member n of the rack n1 is also returned to the outside and returned to its original position.

[Problems to be solved by the device]

 However, since the former chain pin cutting device described above is provided so that a pair of left and right cylinder devices g and h are operated so as to face each other at the same time, if they are operated for a long time, wear and cutting will occur. Operational errors may occur due to vibrations during use, and since a pair of left and right cylinder devices g and h are used at the same time, the left and right cylinder devices g and h must be replaced at the same time during maintenance and inspection. Therefore, it is difficult to provide at low cost.

On the other hand, the latter chain pin cutting device described above uses the racks k1 and n1 and the gears of the pinion m, so that vibration and noise are generated due to backlash of these gears. Then, an operation error may occur, and the number of components increases, which makes it difficult to provide at low cost.

In order to solve the above-mentioned problems, the present invention uses only a cylinder device as a drive source and does not use gears, thereby preventing vibration and noise from occurring and eliminating an operating error.
