Embodiment
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
The present invention relates to the structure, measuring method, Measurement Algorithm of measuring apparatus.
First embodiment：
Expressed structure of the invention as shown in Figure 1, Figure 2, is a kind of caliber parameter measurement mechanism, including rack 1, for surveying
Measure the caliber of measured tube 4.
In order to solve the problems, such as existing in the prior art and overcome its defect, the convenient measurement for carrying out cast tube dimensional parameters is realized
Goal of the invention, the technical solution taken of the present invention is：
As shown in Figure 1 and Figure 2, caliber parameter measurement mechanism of the invention, V-groove 7 is set in the rack 1, described
Measured tube 4 is placed on V-groove 7；Measurement bar is set on the measuring mechanism, and one end of the measurement bar is pacified by shaft 3
In rack 1, the shaft 3 is parallel to V-groove 7；The setting angle encoder 2 in the shaft 3.
As long as V-groove 7 uses two in the longitudinal direction, its structure and size is identical.
Angular encoder 2 is used for measuring the rotation angle of measurement bar；Measurement bar is freely rotated around each shaft 3, and because attaching most importance to
Power falls on measured tube 4, forms a geometry, and measured tube 4 falls on V-groove 7.
The method cost of the present invention is low, and method is simple, can obtain the footpath jump amount of tube outer diameter, tube center position, pipe
Sub- outer diameter.Its is simple in structure, and cost is relatively low, and easy to manufacture is convenient to carry out.
Second embodiment：
The measurement bar includes bar 1, bar 26, and the installation end height of the bar 1 and bar 26 differs.
Angular encoder 2 is used for measurement bar 1, the rotation angle of bar 26；Bar 1, bar 26 are free around respective shaft 3
Rotate, and because gravity falls on measured tube 4, form a geometry, measured tube 4 falls on V-groove 7.
The mechanism can not only measure pipe radial direction circularity, tube outer diameter and center can also be calculated, suitable for pipe
Class product line, and less input, is readily produced line and promotes the use of.
3rd embodiment：
As shown in figure 3, a kind of caliber parameter measurement mechanism of the present invention, including rack 1, for measuring the pipe of measured tube 4
Footpath, two support tubes 8 arranged side by side are set in the rack 1, and the measured tube 4 is placed on two support tubes 8；The survey
Measurement bar is set on measuring mechanism, one end of the measurement bar is installed in rack 1 by shaft 3, the shaft 3 parallel to
Support tube 8；The setting angle encoder 2 in the shaft 3；The measurement bar includes bar 1, bar 26, the bar one
5 and bar 26 installation end height differ.
The support tube 8 can use longer pipe, can also use the very short support roller of axial length.The number of support roller
Amount generally four, the general all same of its size.
Its calculation is identical with second embodiment.
Second embodiment and 3rd embodiment, specifically may also require that：
The bar 1 and its axis of bar 26 are distributed on same vertical guide.So so that coordinate calculates more
It is easy.
Here is measuring principle explanation：
Coordinate and its Choice of Origin such as Fig. 2 and Fig. 3 (X, O, Y) are shown.
After mechanical structure is fixed, point (X1, Y1) and point (X2, Y2) they are fixed, after each part dropping place, bar 1, bar 26 and Y
The angle (K1, K2) of axis determines that.Gained knowledge according to geometry, bar 1, the intersection point (X3, Y3) of bar 26 can try to achieve.K3's
Angle is also easily tried to achieve.
By cutting with the geometrical relationship of two straight lines of a circle it was determined that crossing in the straight line L of intersection point and the center of circle, V-groove
Heart line, is determined by machine-building, thus is also known, and the intersection point of the center line and L are exactly tube center coordinate, pass through geometry
Relation calculates, it can be deduced that pipe diameter.The information such as tube center coordinate, pipe diameter, pipe specification may finally be obtained.
The measuring surface of the measurement bar is overlapped with the axis of shaft 3.So so that measurement is accurate, and coordinate calculates more
It is convenient.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Other occasions are directly applied into by the design of the present invention and technical solution, within protection scope of the present invention.
