It is already known that the cylindrical member 10 and the ring-shaped flange main body 8 can be firmly connected by tightening the ring. For example, this one is
It is used as a coupling device for the deployment mechanism of the solar array paddle mounted on an artificial satellite, and plays an extremely effective role in preventing the solar array paddle from shifting its position from the rotating shaft due to the sudden shock that occurs during the launch of an artificial satellite. ing.

However, although such a coupling device can firmly couple the cylindrical member 10 and the ring-shaped flange body 8, it is extremely difficult to align the pinholes when re-coupling them after their removal. Therefore, a considerable amount of time and effort is expended during the operation of connecting the cylindrical member and the ring-shaped flange, and improvements in this aspect have been strongly desired.

[Purpose of invention]

The present invention was developed in response to these demands, and its purpose is to provide a coupling device that eliminates the troublesome pinhole alignment operation, is easy to handle, and has high coupling reliability. There is a particular thing.

[Summary of the idea]

That is, the present invention has been made to achieve the above-mentioned object, and includes a tapered through hole that tapers in the inner circumferential direction in the peripheral wall of a ring-shaped flange body in which a split gap is formed into which a cylindrical member is inserted. At the same time, at positions corresponding to the through holes of a pair of clamping clampers placed on the outside of this ring-shaped flange,
A tap hole with a larger diameter than the above-mentioned through-hole is provided, and a taper bolt holding nut having an inner diameter larger than the outer diameter of the threaded part of the taper bolt having a tapered head corresponding to the above-mentioned tapered through-hole is screwed into each of the tap holes. It is characterized by the fact that

[Example of idea]

A preferred embodiment of the present invention will be described below with reference to FIGS. 3 and 4. 1 is a cylindrical member such as a rotating shaft, and 2 is a ring that allows the cylindrical member 1 to be fitted into a ring-shaped main body. The flange 2 has a gap 2a in the center so that the diameter can be reduced during compression, and is integrally connected to, for example, a solar cell paddle (not shown). This flange 2 has a tapered through hole 2 formed in a proper position on its outer periphery and tapered toward the inner periphery.
b... and clamp bolt insertion holes 2c... on both sides thereof.
The clamping parts 21, 21 are clamped and tightened by a pair of clamping clampers 3, which will be described later.

Each of the pair of clamping clampers 3, 3 is formed into a substantially semi-cylindrical shape according to the main body shape of the ring-shaped flanges 2, 2 so as to be placed over the outside of the ring-shaped flanges 2, 2, and , 2, tap holes 3a having a larger diameter than the taper holes 2b are formed in the flanges 2, 2 at positions corresponding to the taper holes 2b.

Tap holes 3a formed in the clamping clampers 3, 3
Each of the taper bolts 4 has an inner diameter B larger than the outer diameter A of the threaded part of the tapered bolt 4, which has a tapered head 4a corresponding to the tapered through hole 2b... drilled in the flanges 2, 2.
A taper bolt retaining nut 5 is removably screwed into the housing. The tapered bolt 4 has its tapered head 4a protruding from the tapered through hole 2b of the flange 2 so as to support the cylindrical member 1 from three sides of the outer peripheral surface of the cylindrical member 1.

6 is a clamp block, and 7 is a clamp bolt, which is used to tighten the above-mentioned pair of clamping clampers 3, 3 to the ring-shaped flange 2.
That is, as shown in FIGS. 3 and 4, the clamp blocks 6 are applied to the upper and lower sides of the pair of clamping clampers 3, 3, and the clamping blocks 6 are attached to the upper and lower sides of the pair of clamping clampers 3, 3 by screwing together the clamping bolts 7. , 3 are tightened to reduce the diameter of the ring-shaped flange 2, and cooperate with the above-mentioned taper bolt 4 to firmly connect the cylindrical member 1 to the flange 2.
The clamp blocks 6 are of a twin type in the illustrated example, but they may be formed independently like a normal nut.

When the ring-shaped flange 2 is to be coupled to the cylindrical member using the coupling device of the present invention, the cylindrical member 1 is fitted into the ring-shaped flange 2, and then the ring-shaped flange 2 is inserted from both upper and lower sides. After covering the clamping clampers 3, 3 and engaging the clamp bolt 7 with the clamp block 6 to tighten the clamping clampers 3, 3 appropriately,
Insert the taper bolts 4 into the tap holes 3a of No. 3 and the taper through holes 2b of the flange 2, and then press the taper bolts 4 with the taper bolt retaining nuts 5 to tighten the outer periphery of the cylindrical member 1 into the taper through holes 2b. ...The cylindrical member 1 can be firmly connected to the flange 2 by being supported by the tapered head 4a of the tapered bolt 4 that protrudes further. Therefore, the taper bolt 4 can be inserted smoothly into the taper through-hole 2b by tightening the clamp bolt 7, and installation errors can be absorbed by the gap between the threaded portion of the taper bolt 4 and the taper bolt holding nut 5. This eliminates the need for troublesome pinhole alignment. That is,
Both the head of the taper bolt 4 and the taper through hole 2b are tapered, and the outer diameter of the tip of the head of the taper bolt 4 is smaller than the inner diameter of the insertion opening of the taper through hole 2b.
taper bolt 4 without precise positioning.
can be easily inserted into the tapered through hole 2b. In this case, since the bolt and the through hole are tapered, the bolt easily slides during insertion, facilitating smooth insertion into the through hole.Furthermore, by tightening the clamp bolt 7, the tapered head 4a and the through hole 2b can be brought into close contact with each other, and this has the effect of making it possible to firmly fix the parts without wobbling.

In addition, when removing the cylindrical member 1 from the ring-shaped flange 2, remove the holding nuts 5 from each tap hole 3a, loosen the clamp bolt 7, and remove the taper bolt 4.
can be easily extracted from the ring-shaped flange 2. Also in this case, since the bolt and the through hole are tapered, the frictional resistance is small and the tapered bolt 4 can be easily extracted.

Furthermore, if the tapered bolt 4 is tightened so strongly that the tapered head 4a of the tapered bolt 4 digs deeply into the taper hole 2b of the ring-shaped flange 2, after removing the taper bolt holding nut 5... ...If you screw in another nut (not shown) with a larger diameter until its outer periphery abuts the outer periphery of the tap hole 3a..., the taper bolt 4 will be forcibly retreated, so the taper bolt The tapered head 4a of No. 4 is fitted into the tapered through hole 2b more slowly and can be easily removed.
Therefore, the tapered bolt 4 has its tapered head 4
It can be used with peace of mind because it does not cause the tip a to dig deeply into the tapered through hole 2b and become impossible to get out. In the above embodiment, the outer periphery of the cylindrical member 1 was supported by the tapered bolt 4, but
The cylindrical member 1 may also be provided with a tapered through hole and the taper bolt 4 may be inserted into the hole to secure the cylindrical member 1. In this case as well, the bolt can be easily inserted into and pulled out from the through hole as described above. can be done.

[Effect of idea]

As can be understood from the detailed description above, according to the present invention, the taper bolt holding nut 5, which has an inner diameter larger than the outer diameter of the threaded portion of the taper bolt 4, is screwed into the tap hole 3a of the clamping clamper 3 to tighten the taper bolt 4. Since it is pressed down, the cylindrical member 1 can be firmly connected to the ring-shaped flange 2 by simply engaging the clamp bolt 7 with the clamp lock 6, and the hole for pin driving, which was conventionally considered troublesome, can be positioned accurately. There is no need for any effort to put them together. Also, by removing the taper bolt holding nut 5 screwed into the tap hole 3a of the clamping clamper 3, loosening the clamp bolt 7, and pulling out the taper bolt 4, the cylindrical member 1 can be easily pulled out from the ring-shaped flange 2. It is possible to provide a coupling device that is highly reliable and extremely easy to operate.
