Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reflecting mirror support mechanism, and more particularly to improvements in the lever used in the mechanism.

[Conventional technology]

FIG. 5 is a diagram showing a conventionally used supporting mechanism for a reflecting mirror.

In the figure, 1 is a reflecting mirror, 2 is a cell, and 8.9 is a unit support mechanism lever, which is classified into a bottom support lever 8 and a side support lever 9, depending on the surface of the mirror that the lever supports. .

Each lever is basically constructed as shown in Fig. 6. In the figure, 3 is a load shaft that supports the reflecting mirror, and 4 is a load shaft that supports the reflector.
is a short arm, 5 is a lever fulcrum, 6 is a long arm, and 7 is a weight.

In this support mechanism, the fulcrum part 5 of the lever is attached to the cell 2, the load shaft 3 of the lever is attached to the side surface of the reflecting mirror 1 through a member, and the load shaft 3 of the lever is attached to the side surface of the reflector l via a member. A receiver (not shown) attached to the bottom surface of the reflecting mirror 1 is configured to be attached via a plate.

Next, the operation will be explained.

When the reflector 1 faces toward the zenith as shown in FIG. 5, the weight of the reflector 1 acts only on the bottom support lever 8 and does not act on the side support lever 9. By appropriately adjusting in advance the weight of the weight 7 and the length of the arm from the fulcrum 5 to the weight 7, the sum of the forces exerted by the two 8 load shafts 3 on the bottom support can be adjusted to the reflector 1. It is possible to balance the weight of In this way, the bottom support lever 8 can be used without the reflector 1 touching the cell 2.
It can only be held by

Further, when the reflecting mirror 1 faces in the horizontal direction, the weight of the mirror acts only on the side support levers 9 and does not act on the bottom support levers 8. At this time, as in the case of the bottom support lever, by appropriately adjusting the weight of the weight 7 and the length of the arm from the fulcrum 5 to the weight 7, the reflector 1 is moved only by the side support lever 9. It becomes possible to hold it by.

If you adjust the levers in each of the zenith and horizontal directions as described above, you can see the reflection! II! Even when l faces in an intermediate direction, the side support levers 9 and the bottom support levers 8 share the responsibility of holding the reflecting mirror 1.

These levers are arranged by appropriately selecting their number and supporting position for the purpose of suppressing deformation that occurs on the mirror surface when the reflecting mirror changes its attitude with respect to the direction of gravity.

[Problem to be solved by the invention]

The lever applied to the conventional reflector support mechanism is constructed as described above, and little attention has been paid to the accuracy of attachment to the reflector or cell. However, as reflectors have become larger and higher light focusing accuracy has been required, when the mirror is in the zenith position, the bottom support lever is attached to the long arm, and the side support lever is attached to the load axis at each horizontal position. In response to the need to increase the accuracy of power, in addition to the conventional function of simply levers, mounting is now required to have the ability to detect and adjust accuracy.

The present invention was made in view of the above-mentioned requirements, and it is possible to easily detect the horizontality of the load shaft when the reflector support mechanism is mounted, the arm for the bottom support lever, and the horizontality of the load shaft for the side support. The purpose of the present invention is to provide a reflector support mechanism.

[Means to solve the problem]

The reflector support mechanism according to the present invention includes an arm supported on a fulcrum, and an arm attached to one end of the arm,
Using a bottom and side support lever consisting of a load shaft that supports the bottom and sides of the reflector and a weight attached to the other end of the arm, the iron is placed on the long arm when supported on the bottom, and the load is placed on the long arm when supported on the side. The shaft is equipped with a mechanism that detects the horizontality of the arm and load shaft, respectively.

[Effect]

In this invention, in the levers that are unit support mechanisms constituting the reflector support mechanism, detection mechanisms are provided on the arms of the bottom support lever and on the load shafts of the side support levers to detect the horizontality of the arms and load shafts, respectively. Therefore, after the lever is fixedly attached to the cell and the reflector, it is possible to easily detect and adjust the horizontal state of the arm and the load axis on the side to which the mechanism is attached.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1(a) is a diagram showing a levelness detection mechanism for detecting levelness according to an embodiment of the present invention.

In the figure, 11 is the axis of this mechanism, 12 is a horizontality detection gauge, and radial line segments 17a with equal pitches centered on axis 11 are formed on a transparent material such as an acrylic plate.

Three lines 17b and 17c are drawn, and the central line segment 17b is called the center line for convenience. 13 is the balance weight of the horizontality detection gauge 12, and 14 is the connection between the shaft 11 and the balance weight 13. balance weight・
The bar is selected in weight and length so as to cancel the moment exerted by the horizontality detection gauge 12 on the shaft 11, and is provided so as to be located on an extension of the center line 17b. 15 is a counterweight, 16 is a counterweight bar that connects the shaft 11 and the counterweight 15, and the moment with respect to the shaft 11 is measured by a gauge 12. Balance weight 13. The weight and length of the balance weight bar 14, etc. are set to be sufficiently larger than the moment exerted by the balance weight bar 14, etc., and
It is positioned so as to form a line 90' with the center line 17b centering on the axis If. The moment here is the product of the weight of the weight and the distance from the center of rotation to the center of gravity of the weight.

In the horizontality detection mechanism according to the present invention shown in FIG. 1(a), when the horizontal axis 11 of the machine is held horizontally, the counterweight 15, where the moment with respect to the same axis is maximum, faces downward in the vertical direction. center line 1 of the horizontality detection gauge 12
7b points in the horizontal direction.

Therefore, if the shaft 11 of the horizontality detection mechanism is inserted into the lever hole 10 provided in the long arm of the bottom support lever 8 shown in FIG.
Whether or not the long arm 6 is horizontal can be determined based on whether or not the long arm 6 coincides with the center a 17 b of 2. Also, if you know in advance the angle that the two line segments 17a and 17c make with the center line 17b,
By inserting the reference line 2° between these two line segments 17a and 17c, it is also possible to find out how much horizontality is within the angle between the center line 17b and the two line segments.

As described above, in this embodiment, by providing the lever 8 constituting the reflecting mirror support mechanism with a horizontality detection mechanism for detecting the horizontality of the arm 6, the arm 6 on the side to which the mechanism is attached becomes horizontal. It is possible to easily detect the state of

Furthermore, in the two embodiments described above, the horizontality detection gauge I2
Although three radial line segments are shown in Figure 3, if the center line 17b is omitted and only two line segments are drawn as shown in Figure 3, there is no difference in function. , the above-mentioned center line 17b is an imaginary line segment located at a distance such as from two line segments.

Furthermore, while the horizontality detection gauge 12 has been shown as a line segment drawn on a transparent plate material, as shown in FIG.
You can open and configure the . Even in this case, the center line 17b may be omitted.
