That is, a conical guide member 3 is attached to one end of the shaft member 2 to which the C-shaped retaining ring 1 is to be assembled, and the C-shaped retaining ring 1 is fitted around the outer periphery of this guide member 3. To assemble this C-shaped retaining ring 1, the head member 4 presses the C-shaped retaining ring 1, so that the inner diameter of the C-shaped retaining ring 1 is forcibly pressed against the inclined surface 3a formed on the outer periphery of the guide member 3. A method is adopted in which the shaft member 2 is moved downward while expanding in diameter, and is fitted into the groove e2a formed on the outer periphery of the shaft member 2.

Claw portion L5b formed at the tip of 5, L5b, 1
After placing a C-shaped retaining ring 1t on the outer periphery of the cylinder 5b, when working fluid is supplied into the lower chamber 9 from the lower supply/discharge port 6 provided in the lower cylinder 19, the fluid pressure is increased and the pressure is increased in the vertical direction. The piston 10 moves upward with respect to the cylinder 7 which remains stationary. At that time, the piston rod 11 also moves upward in accordance with the upward movement of the piston 1o. In this case, the spring constants of the first elastic body 13 and @2 elastic body 16 are equal to the lower end surface of the lower cylinder 19 and the stopper! l! Since the value is set such that the first elastic body 13 and the second elastic body 23 are not compressed until the upper end surfaces of the first elastic body 13 and the second elastic body 23 touch each other. Therefore, as the piston rod 11 moves upward, the entire case sphere also moves upward. A friend of mine once said that the sea urchin shown in Figure 5 was

部材部、２５に押し当てられ、これら規制部材部。Subsequently, when the working fluid is supplied into the lower chamber 9, the upper part of the case 12 is blocked by the stopper part 23 as described above, so that only the piston rod 11 is moved into the first elastic body 1.
Therefore, the pressing portion 1 provided at the upper end of the piston rod 11 moves upward against the spring force of the piston rod 11.
The t cam surfaces 15 &... formed on the inner circumference of each of the diameter-expanding members 15, 15, 15 are pressed by the spherical surface of 7, and the upper end of each diameter-expanding member 15, 15, 15 is , a pivoting agent 14 provided at the upper end of the case 12 rotates toward the entire center in a direction that increases the diameter of the second elastic body 16 against the spring force of the second elastic body 16 . Each diameter expanding member 15
, 15, the claw portion 15b formed at the upper end of 15...
- Since the diameter is expanded in the same direction, the diameter of the C-shaped retaining ring 1 can be expanded outward by the claw portions 15b, as shown in FIGS. 1 and 6. After this, the working fluid is introduced into the right chamber 33 of the cylinder 31 provided in the expanded diameter state holding device 24, and the piston, which is slidably inserted into the ZIJ cylinder 31, moves to the left. Accordingly, the slide 1I2IFa material n fixed to the piston 34 via the piston rod 35 moves to the left while being guided by the guide bushes 28 provided on the guide holding member device. Therefore, as shown in FIG. It is inserted into the formed gap IC, and the open ends 1a, 1m are slightly pushed apart by the inclined surface formed on the outside 41C of the comb r index 1!1126a. Due to their intersection and the spring action of the C-shaped retaining ring 1 itself,
The entire C-shaped retaining ring 1 has its outer peripheral surface pressed against two protrusion regulating member parts 25, and these regulating member parts.

Ｃ形止め輪１の拡径保持動作が完了する。The C-shaped retaining ring 1 is expanded in diameter between the four and the wedge-shaped portions 26&, and the C-shaped retaining ring 1 has a diameter expanded between each of the expanded diameter members 15, 15, 15.
is formed and separates from the friend claws 115b... In this case, the C-shaped retaining ring 1 has two protrusion regulating members 25 and 25.
At the same time, the position of the metal on the left outer circumferential surface is regulated by the wedge member 26, and the position of the free end 1a, 1a side of it is regulated by the wedge member 26. is maintained. This completes the operation of holding the C-shaped retaining ring 1 in an expanded diameter state by the expanded diameter state holding device 24.

完了することとなる。By doing this, the diameter expanding device is separated from the diameter expanding state holding device 24. Thereafter, the support member 21 of the cylinder device 20 is moved horizontally to a predetermined position of the 6c-type retaining ring conveying device containing the diameter expanding device. Then, the diameter expanding members 15 , 15 , 15 of the diameter expanding device A are transferred from the conveying device to
Is the catch of C-shaped retaining ring 1 to 15 passed? :pine tree. On the other hand, as shown in FIG. 7, the shaft member 2 is inserted into the inside of the C-shaped retaining ring 1 whose diameter has been expanded by the expanded diameter state maintaining device 24, and the shaft member 2 is inserted into the inside of the C-shaped retaining ring 1 whose diameter is expanded by the expanded diameter state maintaining device 24. sliding member 2
By moving 7 to the right, the wedge-shaped portion 26at of the barb member 26 is moved away from the open ends 1a, 1a of the C-shaped retaining ring 1, and the diameter of the C-shaped retaining ring 1 is reduced inward. It is fitted into a groove formed on the outer periphery of the shaft 2. Note that when the C-shaped retaining ring 1 is reduced in diameter, it may be twisted relative to the shaft member 2 and the force of the released end = 1a, 1m may be caught on the edge of the groove, so the guide holding Part 2
A pushing member 36 is attached to be movable up and down relative to 9.
At this point, press all three locations of the C-shaped retaining ring 1, including the open ends 1a, 1a and the center 1b of the body, to ensure that the retaining ring 1 is pushed into the groove. This completes the operation of fitting the C-shaped retaining ring 1 into the groove.

。In this way, the expanded diameter state holding device 241 according to this embodiment
C! In this case, the C-shaped retaining ring 1t-1, which has been expanded to a predetermined diameter state in the diameter expansion device, is expanded for a certain period of time by the two members, the protrusion regulating member 25°5 and the wedge member 26. Since the shaft can be held in its diametrical state, the entire shaft I material 2 can be easily and quickly inserted into the C-shaped retaining ring 1. 26 was pulled out from within the gap IC formed between both open ends 1a of the C-shaped retaining ring 1, and the entire C-shaped retaining ring 1 was formed on the shaft member 2. It can be deposited within the groove.

とかできるという効果が得られる。Effects of the Invention As is clear from the above explanation, according to the present invention, the tCC type retaining ring whose diameter has been expanded to a predetermined diameter enlarged state is made by working together with two members, each of the protrusion regulating members and the wedge RFI member. While it is possible to hold the knife while it is in its enlarged diameter state, following that,
By the action of the cylinder machine front, the diameter of the C-shaped retaining ring, which is in the expanded diameter state, can be reduced to its original state before diameter expansion. Therefore, the work of holding the C-shaped retaining ring in the expanded diameter state and the work of changing the diameter from the expanded state to the expanded state do not require human labor, and automatic fishing can be performed using simple sequence control. You can get the effect of being able to do something.
