アンテナ反射鏡面調整装置が考えられている。(Prior Art) As is well known, in this type of antenna device, an antenna reflecting mirror having a thin shell surface thereof is assembled on an antenna back surface supporting structure with a predetermined mirror surface accuracy. Further, such an antenna device is conventionally an antenna that adjusts the mirror surface precision by pre-tensioning the antenna reflecting mirror for a large-diameter mesh antenna or the like in advance and pulling the tensioned reflecting mirror surface with a thin wire. Some of them are equipped with a reflecting mirror surface adjusting device, but all of them are difficult to apply to a shell surface to which no pretension is applied. Therefore, recently, an antenna reflecting mirror surface adjusting device shown in FIGS. 5 and 6 which can be applied to a reflecting mirror surface using a shell surface has been considered.

ド２の長さを調整して鏡面精度を調整するものである。The antenna reflecting mirror surface adjusting device shown in FIG. 5 is of a so-called turnbuckle type, and one end of a rod 2 to which a turnbuckle 1 which can be screwed and adjusted at an intermediate portion is attached to an antenna reflecting mirror 3 via a spherical bearing 4. And the other end is connected to the mirror surface support structure 5 for supporting the antenna reflector via the spherical bearing 6, and the rotation operation of the turnbuckle 1 adjusts the length of the rod 2 to adjust the mirror surface accuracy. To do.

が非常に悪いという問題を有していた。However, in the above antenna reflecting mirror surface adjusting device, since the gap between the antenna reflecting mirror 3 and the mirror surface supporting structure 5 is required to be a predetermined length due to its structure, the antenna reflecting mirror surface adjusting device becomes large, and the play (play) of the turnbuckle 1 is small. There is a problem in that the adjustment accuracy is very poor because the adjustment is difficult and the adjustment position may shift when locked.

The clamp 11 fixed to the support structure 5 is screwed through a nut 12. When adjusting, the rod 7 is first rotated and screwed to adjust the position of the antenna reflector 3, and when the adjustment is completed, the nuts 10 and 12 are tightened to adjust the rod 7 to the adjusted position.

Therefore, there is a problem in that the positional deviation easily occurs and the reliability of the adjustment is poor. Further, according to this, there is also a problem that the structure becomes complicated due to its configuration.

る回転操作部24bが形成されている。FIG. 1 shows an antenna reflecting mirror surface adjusting device according to an embodiment of the present invention. In the drawing, numeral 20 is formed of, for example, a Ti alloy having a small coefficient of thermal expansion fixed to an antenna reflecting mirror 21 made of CFRP. It is a housing. As shown in FIG. 2, a ball 22 made of, for example, a steel ball for bearings is housed in the huffing 20 with a predetermined clearance using a cap 23 made of, for example, a Ti alloy. For example, inclined surfaces (tapered surfaces) 20a and 23a are formed on the housing 20 and the cap 23 corresponding to the balls, and the tapered surfaces 20a and 23a are subjected to vacuum lubrication such as Teflon coating. The ball 22 is linearly contacted with the tapered surfaces 20a, 23a of the housing 20 and the cap 23, and is housed so as to have desired clearance adjustment accuracy and friction. Then, one end of a mirror surface supporting member 24 called a rod made of a lightweight material such as CFRP or light metal is bonded to the ball 22, for example. A screw portion 24a is formed at the other end of the mirror surface supporting member 24, and the screw portion 24a is fixed to the antenna support structure 25, for example, CFR.
It is screwed onto a base member 26 formed of a lightweight material such as P or light metal. A lock screw 27 for locking the mirror surface supporting member is screwed to the base member 26 in correspondence with the mirror surface supporting member 24. Further, in the mirror surface support member 24, for example
A collar 28 made of a lightweight material such as CFRP or light metal is attached via a set screw 29, and the collar 29 and the base member 26 are attached.
A spring member 30 for position regulation is attached between and. A rotation operation part 24b called, for example, a slot is formed at the other end of the mirror surface support member 24.

度が所望の状態に正確に調整される。In the above structure, when adjusting the mirror surface accuracy of the antenna reflecting mirror 21, first, the lock screw 27 is adjusted to adjust the mirror surface supporting member.
The radial play of 24 is adjusted, and the set screw 29 is mirror-adjusted to set the position of the collar 28 so that the spring force of the spring member 30 is in a desired state. After adjusting the pressure, a jig (not shown) is attached to the rotation operation portion 24b of the surface support member 24 and rotated in the clockwise or counterclockwise direction in the figure. Then, the mirror surface supporting member 24 has the screw portion 24a.
The threaded state between the base member 26 and the base member 26 is adjusted so that the axial direction (arrow
It is moved while being regulated by the spring member 30 in the A and B directions.
As a result, the mirror surface support member 24 is moved along with it,
The antenna reflector is moved in the directions of arrows A and B through the housing 20 and the ball 22 in the cap 23, and the mirror surface precision is accurately adjusted to a desired state there.

量化の向上も図り得るものである。As described above, in the antenna reflecting mirror surface adjusting device, when the mirror surface supporting member 24 is rotated, the surface supporting member 24 is rotated by the spring member 30.
Also, the lock screw 27 is screwed and adjusted while being axially and radially regulated, so that the mirror surface precision of the antenna reflecting mirror 21 is accurately adjusted.
It is possible to perform highly accurate adjustment by a simple operation only by rotating the mirror surface supporting member 24, and further, it is possible to achieve a reduction in size and weight as compared with the conventional one.

It is also possible to configure the housing 20 and the cap 23 so as to be in spherical contact with each other.
In this case, in order to properly set the clearance for the ball 22, it is necessary to improve the processing accuracy of the contact surface.
