Предмет изобретени Subject invention
Приснособление дл разметки центровых линий на детал х, содержащее разметочную нлиту, установленный на этой плите корнус и размещенные на нем две базирующие призмы , отличающеес тем, что, с целью повышени производительности, вершины обеих призм расположены на равном рассто нии от разметочной плоскости плиты, а угол при вершине одной из призм выбран из условий:A device for marking the center lines on the parts, which contains a marker nlita, a Cornus mounted on this plate and two base prisms placed on it, characterized in that, in order to increase productivity, the tops of both prisms are located at an equal distance from the plate marking plane, and the angle at the top of one of the prisms is selected from the following conditions:
р а 2агс sin - ;p and 2ags sin -;

где R - радиус размечаемой детали;where R is the radius of the marked part;
L - рассто ние между центром размечаемой детали и вершиной призмы.L is the distance between the center of the marking part and the top of the prism.
