Изобретение относитс к измерительной технике , предназначено дл определени углового положени одного объекта относительно другого и может найти применение в практике решени различных юстировочных, сборочных и эксплуатационных задач, св занных с угловой ориентацией объектов.The invention relates to a measurement technique, is intended to determine the angular position of one object relative to another, and may find application in the practice of solving various alignment, assembly, and operational problems associated with the angular orientation of objects.

Известен отражатель дл зггломерного устройства, выполненный в виде триппельпризмы и элемента с сильным хроматизмом которые устанавливаютс на контролируемый объект Р-З A known reflector for a zglomerny device, made in the form of a tripple prism and an element with strong chromatism, which are mounted on a controlled object R-3

Недостатком этого отражател вл етс малый диапазон измер емых угловых смещений объекта, вызванный применением эле мента с сильным хроматизмом.The disadvantage of this reflector is the small range of measured angular displacements of the object, caused by the use of an element with strong chromatism.

Наиболее близким к изобретению по технической сущности и решаемой задаче вл ет с отражатель дл угломерного устройства, содержащий угловый отражатель, один из двугранных углов которого имеет отступление от во 2 .The closest to the invention in the technical nature and the problem to be solved is with a reflector for an angular device containing an angular reflector, one of the dihedral angles of which has a deviation from 2.

Недостатком этого отражател вл етс сложность его нулевой установки относительно измерительного устройства, вызванна трудоемким процессом его юстировки по отраженному от отражател пучку лучей. Кроме того, при помощи известного отражател можно измер ть только углы скручивани .The disadvantage of this reflector is the complexity of its zero installation relative to the measuring device, caused by the laborious process of its alignment along the beam reflected from the reflector. In addition, with the aid of a known reflector, only twisting angles can be measured.

Цель изобретени - упрощение нулевой установки отражател .The purpose of the invention is to simplify the zero installation of the reflector.

Это достигаетс тем, что предлагаемый отражатель снабжен визирной трубкой, установленной за уголковым отражателем так, что ее оптическа ось перпендикул рна его входной грани, а уголковый отражатель выполнен с притуплением у вершины по плоскости , параллельной его входной грани, и с возможностью поворота вокруг оси, перпендикул рной входной грани. Входна грань уголкового отражател выполнена полупрозрачной .This is achieved by the fact that the proposed reflector is equipped with a sighting tube installed behind the corner reflector so that its optical axis is perpendicular to its input face, and the corner reflector is blunt at the top along a plane parallel to its input face and can be rotated around the axis, perpendicular input face. The entrance face of the corner reflector is made translucent.

Claims

The drawing schematically shows the proposed reflector for an angular device. It consists of a corner reflector 1, which has a deviation of one of the dihedral angles from 90 ° and is performed with blunting at the apex along a plane parallel to its entrance face, the sighting tube 2 located behind the corner reflector 1. The corner reflector is mounted in frame 3, which the queue is installed in the housing 4 and can be rotated by means of a rotation mechanism 5, for example, a worm gear. A semitransparent coating is applied on the entrance face of the corner reflector. The reflector works as follows. Observing the image of the autocollimator brand (not shown in the drawing) by means of the installation mechanisms of the autocollimator, by rotating it around two axes, one achieves that the image of the brand of autocollimator coincides with the crosshair of the target sight grid. In this case, the optical axis of the autocollimator coincides with the normal to the input face of the angle reflector. The visual can have a large field of vision, and such an operation is easily performed. After this, a zero-angle reflector installation is performed. The installation is carried out by rotating the corner reflector around an axis that coincides with the normal to its input face. To measure the angles in three coordinates, the input (reflective) face of the corner reflector is used as a mirror. Claim 1. Reflector for an angular device containing an angled reflector, one of the dihedral angles of which has a deviation from 90, characterized in that, in order to simplify the zero installation of the reflector, it is equipped with a sighting tube installed behind the angled reflector so that its optical axis perpendicular to its input face, and the corner reflector is blunt off a vertex along a plane parallel to its input face and can be rotated around an axis perpendicular to the input face. 2. The reflector according to claim 1, which is based on the fact that, for the purpose of measuring angles in three coordinates, the entrance face of the corner reflector is made translucent.
