摘要： An alignment device provides one or more references, such as laser lines and planes in horizontal and vertical orientations. One version of the alignment device includes an optics mounting assembly situated in a pivot socket on a frame to provide an output beam. Multiple spring systems and one or more alignment assemblies align and secure the optics mounting assembly in the socket. As a result, the output beam has a desired orientation with respect to true level. A first spring system directs the optics mounting assembly through the pivot socket. A second spring system holds the optics mounting assembly in communication with the alignment assemblies to reduce system backlash. One implementation of the pivot socket has a surface in the form of a sphere's interior surface. A set of support members on the optics mounting assembly rest on the pivot socket's spherical surface—causing the output reference beam to extend from the center of a sphere including the socket's spherical surface. This reduces the translation of the output reference beam's origin when the optics mounting assembly pivots in the socket.

摘要翻译： 对准装置提供一个或多个参考，例如水平和垂直取向的激光线和平面。 对准装置的一个版本包括位于框架上的枢轴插座中以提供输出光束的光学器件安装组件。 多个弹簧系统和一个或多个对准组件将光学安装组件对准并固定在插座中。 结果，输出光束相对于真实电平具有期望的取向。 第一弹簧系统通过枢轴插座引导光学安装组件。 第二弹簧系统将光学安装组件保持与对准组件连通以减少系统间隙。 枢轴套筒的一个实施例具有球体内表面形式的表面。 光学安装组件上的一组支撑构件位于枢轴插座的球面上，使得输出参考光束从包括插座的球面的球体的中心延伸。 当光学安装组件在插座中枢转时，这减小了输出参考光束原点的平移。
