[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring distortion of a vehicle frame (hereinafter referred to as a measuring device).

[0002]

2. Description of the Related Art Conventionally, a measuring instrument (measurement case) includes a telescopic case bar, short members at both ends of the case bar, and a scale, a support pin and the like which are detachably provided on the short member. Have been. The general measurement method is to contact the support pin of the scale bar with the measurement reference point of the vehicle,
A method of measuring the length by expansion and contraction of the scale bar and a method of measuring the length by supporting the scale bar in the same manner as described above have been considered. There is also a method of measuring the height by attaching a movable scale to a short member of the scale bar.

[0003] The conventional measuring case has the features of being simple, lightweight, and easy to handle, but has a problem that an action for constantly supporting the measuring case is required. For example, when measuring the bottom surface of a vehicle that has risen, it is necessary to support a measurement case, which is troublesome and requires extra work due to the support of other people. Also, the conventional measurement case has a special problem and / or an extra effect such as support of another person when measuring the gradient, which is a little problematic.

Next, as a related prior art, there is a distortion measuring and correcting device for a vehicle frame disclosed in Japanese Patent Laid-Open No. 6-179351. The content is that a frame frame, a pair of frame rail members provided on the frame frame, and a pair of module rail members are provided on the upper surface, and at least two pins are integrally fixed by a base plate extending downward from the bottom surface. A module having a pair of longitudinal members, a support assembly fixed to the top surface, at least two pins extending downward from the bottom surface, and fixed integrally with a base plate provided with cutouts on each of four side surfaces. A module having a pair of longitudinal members and a base plate having a support assembly fixed to the upper surface, at least two pins extending upward from the lower surface, and a notch provided on each of four side surfaces. And a wedge member having a lateral hole passing through two legs serving as enlarged heads, a wedge plate having an oblong hole, and a lateral hole and a wedge Of a strain measuring correction apparatus for vehicle frame and a wedge assembly having a Kusabipin extending through the elongated hole. Therefore, the present invention is characterized in that it is possible to accurately, quickly and surely fix a shake table or the like to a frame.

[0005]

The above-mentioned document is directed to a caster-movable strain measurement, which is unsuitable for measurement on the upper surface side of a vehicle, and requires time and effort to move. And a pair of frame members, a modular rail member, and a base, and there are problems such as a complicated structure and an increase in cost.
