Acute angle measuring tool

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 [0001] The invention relates to the field of aircraft production line measurement, in particular to an acute angle measurement tool. Background technique [0002] In the existing aircraft production process, there is no fast and effective method and instrument for measuring the angle between the two sides of the product. Especially for two disjoint surfaces and irregular surfaces, there is no other accurate and effective method except using laser tracker for measurement. However, using a laser tracker for measurement requires professional and expensive instruments and multiple personnel to operate. During the measurement process, multiple points need to be measured to complete the angle measurement. The operation takes a long time, and the selection of points is greatly affected by the measurement surface. , At the same time, due to the many links, the error accumulation of the instrument and human factors will affect the accuracy of the measured value.

However, using a laser tracker for measurement requires professional and expensive instruments and multiple personnel to operate. During the measurement process, multiple points need to be measured to complete the angle measurement. The operation takes a long time, and the selection of points is greatly affected by the measurement surface. At the same time, due to many links, the error accumulation of the instrument and human factors will affect the accuracy of the measured value
