Abstract

The invention discloses a lens-fixing alignment instrument and a using method thereof. The lens-fixing alignment instrument comprises a main cylinder, an objective lens, a focusing lens, a rectangular prism, an eye lens cylinder, and a connecting seat, wherein three groups of eye lens are mounted in the eyepiece cylinder which has a medial axis Y perpendicular to an internal medial axis X of the main cylinder; the connecting seat is mounted at the bottom end of the main cylinder and has a medial axis coinciding with the internal medial axis X of the main cylinder. The lens-fixing alignment instrument and the method are adopted for detection, not only are measuring accuracy greatly improved, time saved, but also the mounting is easy and simple, the operation is quick, and the error is smaller. Moreover, the production cost is small.

Description

technical field [0001] The invention relates to the field of surveying, in particular to a surveying and mapping instrument, in particular to a fixed mirror alignment instrument and a method for using the same. Background technique [0002] The processing of large-span holes has always been a technical problem in the manufacturing process of structural parts. Especially in the aircraft assembly process, long-span holes are prevalent. At present, high-precision collimators cannot be produced on the market, and there are many problems such as low mirror accuracy and excessive errors. For the needs of assembly, some workpieces need to be provided with two opposite cylinders on the same axis, one hole and one cylinder or two holes. In order to ensure that the workpiece is qualified, it is necessary to measure whether the coaxiality of the two cylinders, the hole and the cylinder or the two holes meets the specifications. Existing measurement methods generally use three-dimens...
