DEVICE FOR MEASURING STRAIGHTNESS OF ANGLE AND PLANE

摘要

PURPOSE: A device for measuring straghtness of an angle and plane is provided to improve the quality of maintenance by easily and periodically checking the worn-out states of measurement positions. CONSTITUTION: A base frame has a horizontal beam. A horizontal slider(120) glides along the horizontal beam. A fixed frame(140) fixed on the rear face of the horizontal slider has a U-shaped operating recess(142). A tester arm(144) is rotatably hinge coupled to the operating recess. An angle adjusting arm(146) is rotatably hinge coupled to the operating recess. An angle adjuster(150) has a spindle(152) fixed on the upper face of the tester arm. A vertical slider(162) is installed to lift along a vertical beam(160) fixed on the rear face of the tester arm. A dial gauge(170) is connected to one face of the vertical slider via a fixing bar(164).
