Abstract
A detecting method for compensating and calculating container coaxiality belongs to the technical field of large-size container detection. The detecting method comprises the steps of respectively drawing a cross intersection on each detected cross section of a large-size container by means of a fishing line, and ensuring a fact that the cross intersection is the central point of the cross section; placing and fixing an optical instrument; placing a calibrated scale on the fishing line, adjusting the focal length of the optical instrument, respectively recording the coordinate of each central point; measuring the distance of each central point by means of a laser range finder or a meter ruler; and inputting the coordinate of each point into a computer for calculation, thereby solving the coaxiality. The detecting method settles a problem that a measurement plane which is established in placing the instrument previously must be superposed with an actual line. Furthermore the detecting method has advantages of reducing measurement difficulty, improving detecting speed and improving measurement precision through compensation calculation. The detecting method is used for detecting coaxility of the large-size container.
Description
Technical field
The present invention relates to a kind of detection method of container axiality is and in particular to a kind of inspection of compensation calculation container axiality
Survey method, belongs to tun detection technique field.
Background technology
When manufacturing tun, the detection of container axiality is most important, and the bigger axiality of container volume is more difficult to control
System, accuracy of detection requirement is stricter, and difficulty is also bigger.Conventional detection we set up datum axis using collimating telescope,
, there is the problems such as detection cycle is long, and detection method is single, in especially instrument being necessarily mounted in the method detecting other points again
On heart line, difficulty is big, uses duration.Shorter and shorter with Product checking construction period, the accuracy of manufacture requires more and more higher, former optics
Detection method cannot meet product duration and required precision.
Content of the invention
Brief overview with regard to the present invention is given below, to provide basic with regard to certain aspects of the invention
Understand.It should be appreciated that this general introduction is not the exhaustive general introduction with regard to the present invention.It is not intended to determine the pass of the present invention
Key or pith, nor is it intended to limit the scope of the present invention.Its purpose only provides some concepts in simplified form,
In this, as the preamble in greater detail discussed after a while.
In consideration of it, according to an aspect of the present invention, it is contemplated that a kind of inspection of compensation calculation container axiality is proposed
Survey method, to solve the difficult problem that the measurement straight line set up during existing placement instrument must be overlapped with actual straight line, reduces
Measurement difficulty, improves detection speed, and so that certainty of measurement is improved by compensation calculation.
