Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
The present invention relates to the structure of measuring equipment, measuring method, Measurement Algorithm.
First embodiment:
Structure of the present invention expressed as shown in Figure 1, Figure 2, being a kind of caliber parameter measurement mechanism, comprising frame 1, for measuring the caliber of measured tube 4.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention of conveniently carrying out the measurement of cast tube dimensional parameters, the technical scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, caliber parameter measurement mechanism of the present invention, described frame 1 arranges V-type groove 7, and described measured tube 4 is placed on V-type groove 7; Described measuring mechanism arranges sounding rod, and one end of described sounding rod is arranged in frame 1 by rotating shaft 3, and described rotating shaft 3 is parallel to V-type groove 7; Setting angle scrambler 2 in described rotating shaft 3.
As long as V-type groove 7 adopts two in the longitudinal direction, its structure, measure-alike.
Angular encoder 2 is used for measuring the anglec of rotation of sounding rod; Sounding rod freely rotates around each rotating shaft 3, and because gravity drops on measured tube 4, form a geometry, measured tube 4 drops on V-type groove 7.
Method cost of the present invention is low, and method is simple, can obtain the footpath jumping amount of tube outer diameter, tube center position, tube outer diameter size.Its structure is simple, and cost is lower, easily manufactures, and is convenient to implement.
Second embodiment:
Described sounding rod comprises bar 1, bar 26, and described bar 1 and the installation end height of bar 26 are not etc.
Angular encoder 2 is used for the anglec of rotation of sounding rod 1, bar 26; Bar 1, bar 26 freely rotate around respective rotating shaft 3, and because gravity drops on measured tube 4, form a geometry, measured tube 4 drops on V-type groove 7.
Pipe circular radial degree not only can be measured by this mechanism, can also calculate tube outer diameter and center, be applicable to tubing product line, and less input, is easy to production line and promotes the use of.
3rd embodiment:
As shown in Figure 3, a kind of caliber parameter measurement mechanism of the present invention, comprises frame 1, and for measuring the caliber of measured tube 4, described frame 1 is arranged two stay pipes 8 arranged side by side, described measured tube 4 is placed on two stay pipes 8; Described measuring mechanism arranges sounding rod, and one end of described sounding rod is arranged in frame 1 by rotating shaft 3, and described rotating shaft 3 is parallel to stay pipe 8; Setting angle scrambler 2 in described rotating shaft 3; Described sounding rod comprises bar 1, bar 26, and described bar 1 and the installation end height of bar 26 are not etc.
