【発明の詳細な説明】
この発明は２点式広範囲寸法測長器の２個の測
定軸を平行に真直度よく摺動させるようするため
の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for sliding the two measurement axes of a two-point wide range dimension measuring device in parallel with good straightness.
２点式広範囲寸法測長器では夫々に測定コンタ
クトを持つた２個の測定軸が互に平行でかつ真直
度よく測長範囲内を摺動することが高精度を得る
ために必要である。 In a two-point wide-range length measuring device, in order to obtain high accuracy, it is necessary that two measuring axes, each having a measuring contact, be parallel to each other and slide within the measuring range with good straightness.
本発明は２個の測定軸が平行度および真直度精
度よく摺動できかつローコストで製作できること
を特徴とする。 The present invention is characterized in that the two measurement axes can slide with high accuracy in parallelism and straightness, and can be manufactured at low cost.
在来の方法については原特許願第57−160665号
に記した通りである。 The conventional method is as described in original patent application No. 57-160665.
次に本発明の実施例について説明する。 Next, examples of the present invention will be described.

は軸の運動が円滑で真直度がよい。また相交る２
平面を真直度よく加工することは容易である。 Normally, cylindrical bearings can be machined with high precision for concentricity of the inner and outer diameters, and for straightness and cylindricity of the outer cylinder.In particular, ball bush guides, which are rolling bearings that apply preload to the sliding parts, have smooth shaft motion and high straightness. Good. 2 intersect again
It is easy to process a flat surface with good straightness.
本発明による構造により２個の測定軸を容易に
真直度、平行度よく摺動させることができるので
高精度な２点式広範囲測長器の製作が容易にでき
ることを特徴とする。 With the structure according to the present invention, the two measurement axes can be easily slid with good straightness and parallelism, so that a highly accurate two-point wide-range length measuring device can be manufactured easily.

にしたものである。Additional Relation Original Patent No. 1649458 (Japanese Patent Publication No. 02-056601) has the advantage of reducing the height of the measuring instrument by arranging the measuring shaft and bearing in parallel, but has the disadvantage of increasing the width. This improved invention is designed to reduce the width and simplify the structure by arranging the measuring shaft and bearing in a straight line when the measuring range is relatively narrow.
