DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing used for inspecting a vertical state of a measured object and correcting the measured object to a vertical state as required.

[0002]

2. Description of the Related Art A contact body having a contact surface capable of contacting a surface to be measured in a height direction of an object to be measured,
It is conventionally known that the contact body is composed of a weight connected via a filament so as to be able to hang down from the contact surface at a position separated by a predetermined distance in the internal law from the contact surface. Usually, the contact body is used by temporarily fixing it to the object to be measured. In use, when the contact surface of the down swing is brought into contact with the surface to be measured of the object to be measured, the weight is suspended from the base point via the filament. In this state, the distance between an appropriate position on the filament and the surface to be measured is determined by a right angle ruler or the like,
This measured distance is compared with the predetermined distance of the downward swing.
If these two distances match, the measured surface is confirmed to be in a vertical state, and if these two distances do not match, it is confirmed that the measured surface is in a non-vertical state.

In order to inspect the vertical state of a device under test,
The inspection operation including the actual measurement of the distance, the comparison of the two distances, and the like is repeated for each of a pair of adjacent measurement surfaces in the height direction of the measurement object.

[0004]

However, in the conventional swing-down operation, the inspection work is repeated for each of the two surfaces to be measured in order to inspect the vertical state of the object to be measured. In addition, the inspection work on one measured surface is likely to tilt the other measured surface. Therefore, to adjust both measured surfaces simultaneously to a vertical state with good workability, work for each surface is required. There was a problem because it was repeated.

An object of the present invention is to enable the vertical state of both adjacent measurement surfaces to be inspected simultaneously with a small number of man-hours and at the same time, and to fix the object to be measured in the vertical state. The object is to provide a swing which helps to adjust the surface to a vertical position with good workability without advanced technology at the same time.

[0006]

According to a first aspect of the present invention, there is provided a swing-up swinging device, comprising: a first contact surface capable of contacting a pair of adjacent measurement surfaces in a height direction of an object to be measured; A contact body having a second contact surface, a laser beam emitting device and a laser beam receiver, each of which is located at a predetermined distance from the first contact surface and the second contact surface of the contact body in a direction defined by the internal rule. It consists of a ruler. It is preferable that the base point is provided at a position separated from the first contact surface and the second contact surface of the contact member by a predetermined equidistant distance in the internal rule direction.

According to a second aspect of the present invention, in the above structure, a fixing means for temporarily fixing the contact body to the object to be measured is provided. As this fixing means,
When the object to be measured is an object to be measured made of wood or the like, this is a gradient for increasing the degree of adhesion between the surface to be measured and the abutting body by giving a slope to the cone that can be driven into the object to be measured. If necessary, a conical body which is urged by a spring in the return direction, or when the measurement object is a measurement object made of steel or the like, for example, a magnet which can be attracted to the measurement object can be used.

[0008]

According to the first aspect of the present invention, when the first contact surface and the second contact surface are respectively brought into contact with the adjacent surfaces to be measured of the object to be measured, the laser beam emitted from the base point. Swung up through. In this state, each distance between an appropriate position on the laser beam and each surface to be measured is simultaneously measured by the laser light receiving ruler, and the distance between each actually measured surface is a base point, and the first contact surface and the second contact surface are measured. The vertical state of the first and second contact surfaces can be inspected at the same time when the laser light receiving ruler hits the contact point between the surfaces.

When at least one of the surfaces to be measured is in a non-vertical state, each of the measured distances is set so that each of the measured distances matches a predetermined distance between the base point and the first and second contact surfaces. The inclination of the measuring surface is corrected at the same time.

According to the second aspect of the present invention, during use, the contact body is temporarily fixed to the measured object by the fixing means.

It is also possible to use the upward swing to inspect the vertical state of the cylindrical and cylindrical objects to be measured. In this case, the first abutment surface and the second abutment of the upward swing can be used. The surface is brought into contact with the cylindrical surface to be measured which is far away from the object to be measured, and each distance between an appropriate position of the laser beam and each of the surfaces to be abutted is measured.

The contact body 12 is temporarily fixed to the DUT 1 so that the scratch is not noticeable after the urging. At this time, the raised laser beam is received by a laser beam receiving ruler and the vertical state is measured simultaneously in two directions. When the DUT 1 is made of steel or the like, as the fixing means, instead of the conical state 17, the contact body 12, particularly the first contact body 13 and / or the second contact body surface 1 is used.
