Abstract

Изобретение относитс  к измерительной технике. Цель изобретени  - повышение точности. Угломер содержит основание 1 со шкалой 2, установленный на нем с возможностью перемещени  сектор 3 с нониусом 4, угольник 14 и линейки 16 и 18. При измерении второй сектор 17, установленный на основании 1, перемещают до упора линейки 18 так, чтобы ее рабоча  поверхность находилась в одной плоскости с боковой поверхностью сектора 17 и при помощи механизма микроподачи, установленного на секторе 3, перемещают сектор 3. Между линейками 16 и 18 устанавливают деталь и фиксируют положение сектора 17 дополнительным стопорным узлом, расположенным на секторе 17. Затем убирают деталь, перемещают сектор 17 до соприкосновени  рабочих поверхностей линеек 16 и 18 и стопор т сектор 17. Указанный цикл повтор ют столько раз, чтобы их общее число было равно требуемой кратности повышени  точности отсчета. 4 ил.This invention relates to a measurement technique. The purpose of the invention is to improve accuracy. The protractor contains a base 1 with a scale 2 mounted on it with the ability to move a sector 3 with a nonius 4, a square 14 and rulers 16 and 18. When measuring, the second sector 17 mounted on the base 1 is moved up to the stop of the ruler 18 so that its working surface was in the same plane with the lateral surface of sector 17 and using the micro-feed mechanism installed on sector 3, move sector 3. Between the rulers 16 and 18, install the part and fix the position of sector 17 with an additional stop unit located on sector 17. For remove the part, move sector 17 until the working surfaces of the lines 16 and 18 touch, and stop sector 17. This cycle is repeated so many times that their total number is equal to the required multiplicity of increase in the accuracy of reference. 4 il.
