However, it adopts the vernier principle and the accuracy is generally 2′, and its measurement accuracy is low. At the same time, the measured object must have obvious surfaces, edges or generatrices, and its application range has certain limitations.
Therefore, the existing angle measurement methods or angle measurement instruments still cannot meet the needs of use

Embodiment Construction
[0028] Embodiment of the present invention: when measuring the angle of a mechanical part, a method for measuring an angle of the present invention can be used for measurement. The method is to first make an involute consisting of a fixed length 1, a moving ruler 2 and a rotating shaft 3 An angle measuring instrument, one end of the fixed ruler 1 is hinged with one end of the movable ruler 2 through the rotating shaft 3, and an involute end surface measuring side 1.2 whose end surface shape is an involute curve is made on the other end of the fixed ruler 1, Make the center of the base circle of the involute of the measuring side 1.2 of the involute end surface coincide with the center of the through hole at the fixed-length hinged end and the center of the rotating shaft 3, and make the radius of the base circle rb, and make a measurement on the fixed-length 1 at the same time The fixed-scale angle measurement side 1.1 used during the angle is made on the moving ruler 2 to make...

The invention discloses an angle measuring method and an involute angle measuring instrument thereof. The involute angle measuring instrument comprises a fixed ruler, a movable ruler and a rotating shaft, an involute end face measuring edge with the end face in the shape of an involute curve is made at one end of the fixed ruler, a radius of an involute base circle of the involute end face measuring edge refers to rb, a fixed ruler angle measuring edge is made on the fixed ruler, and a movable ruler angle measuring edge and a linear measuring edge are made on the movable ruler. When the fixed ruler and the movable ruler are closed and the fixed ruler angle measuring edge is parallel to the movable ruler angle measuring edge, an inclined angle between the fixed ruler and the movable ruler is 0 degree, and the linear distance between the linear measuring edge of the movable ruler and a starting point of the involute end face measuring edge of the fixed ruler is Wo; and when the movable ruler is stretched to measure an angle of a measured object, the linear distance between the linear measuring edge of the movable ruler and a measuring point of the involute end face measuring edge of the fixed ruler is Wx, and a value theta of the angle of the measured object is represented as the following formula theta=. The involute angle measuring instrument has the advantages of high measurement precision, simple structure and convenience in use.
Description
technical field [0001] The invention relates to an angle measuring method and an involute angle measuring instrument thereof, belonging to the technical field of angle measurement. Background technique [0002] At present, in the prior art, the commonly used measuring tool for measuring the angle of mechanical parts is a universal angle ruler. Although the universal angle ruler can easily measure the internal and external angles of parts. However, it adopts the vernier principle and the accuracy is generally 2', and its measurement accuracy is low. At the same time, the measured object must have obvious surfaces, edges or generatrices, and its application range has certain limitations. Therefore, the existing angle measuring method or angle measuring instrument still cannot meet the needs of use. Contents of the invention [0003] The object of the present invention is to provide an angle measurement method and its involute angle measuring instrument with high accuracy o...
