Abstract
The invention relates to the field of measurement of airplane production lines, and specifically relates to an acute angle measuring tool. The acute angle measuring tool comprises two contact poles, two supporting rods and a scale plate; the two supporting rods are movably connected through a rotating shaft; the two contact poles are respectively glidingly connected at one of the ends of the two supporting rods, and a fixed included angle is maintained between the contact poles and the supporting rods; the scale plate is positioned at the other one of the ends of the supporting rods; the end part of one supporting rod is fixed to the scale plate, and while the end part of another supporting rod is used as a measuring indicator light; the contact poles are kept in an included angle of 120 degrees with the supporting rods. The acute angle measuring tool has the beneficial effects that the structure is simple, the cost is small, and the use is convenient; the included angle between the complex surfaces of an airplane can be quickly and effectively measured; therefore, the production efficiency can be raised.
Description
Technical field
The present invention relates to Aircraft Production line fields of measurement, relate to a kind of acute angle survey instrument specifically.
Background technology
In existing Aircraft Production process, also measuring method and utensil are not fast and effectively had for the angle on product between two sides.Particularly for two non-intersect, irregular, except adopting laser tracker and measuring, there is no other methods accurately and effectively.But utilize laser tracker to measure, the valuable instrument of specialty and several personnel are needed to operate, need to measure multiple point in measuring process and just can complete angle measurement, the operation used time is longer, the impact chosen by measuring surface of some position is larger, simultaneously because link is more, cause the accumulation of error of instrument and human factor, the accuracy of numerical value is measured in impact.
Summary of the invention
The object of the invention is to solve the problem, a kind of acute angle survey instrument is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of acute angle survey instrument, comprise feeler lever, strut and graduated scale dish, feeler lever and each two of strut, two struts are flexibly connected by rotating shaft, two feeler levers are slidably connected in one end of two struts respectively, and feeler lever and strut keep a fixed angle, and graduated scale dish is positioned at other one end of strut, wherein the end winding support of a strut is on graduated scale dish, and the end of an other strut is used as measurement pointer.
Feeler lever and strut keep 120 ° of fixed angles.
Beneficial effect of the present invention is: structure is simple, with low cost, easy to use, realizes effectively measuring fast for angle between face complicated on aircraft and face, enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention,
Fig. 2 is surveying work schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: see Fig. 1 and Fig. 2.
A kind of acute angle survey instrument, comprise feeler lever 1, strut 2 and graduated scale dish 4, feeler lever 1 and each two of strut 2, two struts 2 are flexibly connected by rotating shaft 3, two feeler levers 1 are slidably connected in one end of two struts 2 respectively, and feeler lever 1 and strut 2 keep a fixed angle, and graduated scale dish 4 is positioned at other one end of strut 2, wherein the end winding support of a strut 2 is on graduated scale dish 4, and the end of an other strut 2 is used as measurement pointer.
Feeler lever 1 and strut 2 keep 120 ° of fixed angles to measure better.
The feeler lever that adjusted design can be required suitable according to the object that will measure or production line and the reading of strut fixed angle and graduated scale dish.
Principle of work of the present invention:
1) first put according to institute's location measuring appliance is adjusted, the adjustment position of feeler lever on strut, so that measure;
2) by measuring appliance feeler lever face A with survey face B and fit;
3) slight oscillatory measuring appliance, adjusts to optimum position;
4) according to quadrilateral interior angle sum be the principle of 360 °, angle beta=(360-120-120)-α.
5) on graduated scale dish, demarcate reading, directly read institute measuring angle β.
Embodiments of the invention announce be one of preferred embodiment also; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present invention; and make different amplifications and change, but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
Claims (2)
