Problems solved by technology

This kind of verification has caused the unreasonable unreasonable use of the high-precision ability of the equipment and the unscientific additional error caused by the indication error caused by the measurement system of the tested instrument.
Searching Chinese patents, no devices and methods to overcome this unreasonable and unscientific were found

Embodiment Construction

[0010] The pentagonal prism base (1) is the part that is formed on the box body that is formed on the left side of the pentagonal cavity (11) and the right side is formed on the cylindrical member (14) that opens along the axial direction. The cylindrical component (14) is shaped on the matching circular hole (16) connected with the alignment device (15) objective lens barrel in the box body side, and is used as the location of the alignment device diverter. Simultaneously by the ribs (29), (30) of the upper and lower edges of the opening, the long axial groove (31) formed and the connection hole (33) on it are connected with the alignment device (15) at the boss place by the screw (28). ) The objective lens barrel is fixedly connected into one. The pentagonal prism (10) is positioned by the right end and the lower end of the left side (pentagonal) cavity inside the pentagonal prism seat (1) and are perpendicular to each other and respectively vertical and parallel to the two ...

Abstract

The invention relates to an alignment device redirector, belongs to the technical field of precise calendar design, surveying instrument manufacture, measuring instrument detection and the like, and mainly solves the technical problem of rotating an alignment object image for 90 degrees around a main optic axis. The alignment device redirector consists of a pentagonal prism mounting part and a right angle prism mounting part. The right angle prism mounting part finishes the positioning and mounting of a right angle prism. The pentagonal prism mounting part finishes the positioning and mountingof a pentagonal prism, and finishes positioning connection with the right angle prism mounting part and the fixed connection of a reserved port and an alignment device. During calibrating focusing operation errors of a theodolite and a total station type electronic tacheometer, the alignment device redirector is matched with the alignment device to produce a high-precision horizontal alignment target for the device.

Description

[0001] The invention relates to a steering gear of an alignment device. technical field [0002] The invention belongs to the technical field of precision optical-mechanical design, surveying and mapping instrument manufacturing and measuring instrument detection. Background technique [0003] In the verification of theodolite and total station type electronic speed measuring instrument (hereinafter referred to as total station), the focus operation error of theodolite and total station must be verified in both horizontal and vertical directions. At present, most metrological verification departments use the alignment device of the precision level theodolite comprehensive inspection instrument as the standard device when verifying the project. The alignment accuracy of the alignment device in the horizontal and plumb directions is inconsistent, and the micrometer of the device is set about the plumb direction, and there is no micrometer in the horizontal direction. For theo...
