となる。<Function> Due to the above configuration, when connecting the chains, the connecting pins are inserted between the roller link putos that are butted at both ends of the outer plate, and the connecting pins are inserted on the holder frame surface. Set the positioning pin so that it stands up between the opposing rollers that form the part. Further, in this case, the other joint link plate is attached to the press-fit block surface within the holder frame with the magnetic rod attached thereto. Thereafter, by turning the pressure bolt appropriately and letting it out, the joint pin is press-fitted into the joint link plate. The end of the joint pin that protrudes from the joint link plate enters the receiving groove, and the head of the press-fit pin escapes, and the amount of press-fit is regulated. If the joint pin is of the caulking type, remove the positioning pin on the holder frame surface, attach it directly to the tip of the pressure bolt, and insert the caulking taper at the tip of the positioning pin onto the joint pin. Place it on the tip and let out the pressure bolt to swage the joint pin end and create a chain connection.

臨み、チエーンの摺れを阻止する。 To explain this function, first, for example, when connecting the roller chain 12, the joint pins 15, 15 installed in advance at both ends of the outer plate 14 are inserted between the opposing roller link plates 13, 13 to be connected.
A bushing 1 arranged at the center of each roller 16, 16
7 and 17, and the tips thereof pass through the roller link plates 13 and 13 on the opposite side. On the other hand, when the joint link plate 18 to be fitted onto the ends of the joint pins 15, 15 is applied to the press-fit block 5 located in the holder frame 1c, the joint link plate 18 is attracted by the magnetic rod 7 provided at the center of the press-fit block 5. are held in contact. Of course, at this time, the positioning pin 8 projects and faces between the opposing rollers 16, 16 to prevent the chain from sliding.

定のチエーン１２の接続となる。 Here, a suitable tool such as a spanner (not shown) is attached to the bolt head 3a of the pressure bolt 3.
When it is turned, the threaded portion 3b is drawn out into the frame and the press-fit block 5 presses the joint link plate 18, so that the joint pins 15, 15 are press-fitted into the fitting holes 19, 19 of the joint link plate 18. Connected. At this time, the press-fit tips 15a, 15a of the joint pins 15, 15 may be pushed in until they come into contact with the wall surface 4a of the receiving groove 4 of the press-fit block 5. That is, the relief of the press-fit pin head and the press-fit amount are defined by the receiving groove 4, and a predetermined connection of the chain 12 is achieved.

入ができる。 In this case, when the width of the joint link plate 18 is smaller than the width of the roller link plate 13, the shape of the press-fit block 5 is changed to a receiving groove 4 as shown in FIG. 3B.
A piece body with a receiving step 20 is used below. That is, the narrow joint link plate 18 is placed on the receiving part 20 of the press-fit block 5, and in this state, the roller link plate 1 with the joint pins 15, 15 protruding is placed.
Even when pressed against the 3 and 13 sides, the joint pins 15 and 15 are press-fitted into predetermined locations and connected in the same manner as described above without falling. Also, the shape of the press-fit block 5 is changed to the third shape.
Similar press-fitting can be achieved by using a receiving groove 4 vertically carved at positions corresponding to the joint pins 15, 15, as shown in FIG.

用的効果を奏する。<Effects of the invention> As mentioned above, the chain joint tool of the invention has the following effects:
A pressure bolt is arranged on one side of the holder having a U-shaped cross section, and a press-fit block with a receiving groove for the head of the press-fit pin supported by a magnetic rod on the inside;
By arranging the tapered positioning pin on the frame surface in a removable manner, it is easy and reliable to press the joint pin into the joint link plate to connect the chain, and the amount of press-fit is automatically adjusted in the receiving groove. stipulated in Moreover, since the magnetic rod faces the center of this press-fit block, the joint link plate can be easily and securely set, and the positioning with respect to the joint pin can be easily performed, resulting in extremely high workability.
Further, since the positioning pin has a taper for caulking at the tip and can be freely attached to the tip of the pressure bolt, it can be satisfactorily used even if the joint pin is a caulking type pin. That is, the pin end can be easily and reliably caulked by the taper. Furthermore,
Since the present invention is an assembly-specific tool with an extremely simple structure, it is compact and can be easily handled without failure or malfunction, and the greatest advantage is that it is inexpensive, which provides practical effects.
