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 mounting of 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
The present invention relates to a kind of alignment device redirector.
Technical field
The invention belongs to accurate ray machine design, the technical field that instrument of surveying and mapping manufacturing and measurement instrument detect.
Background technology
In the calibrating of transit and full site type electronic tachometer (hereinafter to be referred as total powerstation), must level and vertically on the both direction pair warp and weft instrument and total powerstation focusing operating error examine and determine.Present most measurement verification department all uses the directrix device of precision level transit comprehensive checker as standard when this project of calibrating.This directrix device is inconsistent in the directrix precision of level and plummet direction, and the mircrometer gauge of this device is provided with about the plummet direction, and horizontal direction does not have mircrometer gauge.Pair warp and weft instrument and total powerstation, horizontal angle are measured much frequent and precision and are also required highly than the plummet direction, so the horizontal direction component of focusing operating error more should obtain control.It is unreasonable and use the not science of the additive error that the error of indication of being come reading to bring by the measuring system of test examination instrument causes that such calibrating has caused that the ability of equipment degree of precision is not fully used.The retrieval Chinese patent is not found and is overcome this unreasonable and unscientific apparatus and method.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, providing a kind of simple in structure, ray machine member that principle is reliable, easy to use that the graticule image of above-mentioned directrix device is revolved turn 90 degrees, make the horizontal hair of original crosshair become vertical hair, (vertical hair originally becomes horizontal hair).Allow the higher plummet target of directrix precision be used as the horizontal guideline standard, available (this device) mircrometer gauge directly reads the focusing operating error of transit or total powerstation simultaneously.
