Angle measuring device and measuring method thereof

Abstract

The invention provides an angle measuring device and an angle measuring method. The angle measuring device comprises a bracket, a roller set, a first gear set, a second gear set, a shaft system, an angle measuring part and a radial dimension measuring part, wherein the first roller transmits movement to a main graduation bar by the first gear set; and the second roller transmits the movement to a vernier graduation bar by the second gear set, so that circular movement of the roller is converted to be linear and horizontal movement of a rack. The angle measuring device is independent from the circle center on the end surface of a measured component, can accurately measure the specific angle of the component based on the outer circle or the inner hole of the component, is suitable for measuring a rotary angle, and in particular suitable for measuring the angle of similar large gears or gear ring type components in engineering machinery.

Description

technical field [0001] The invention relates to an angle measuring device and a measuring method thereof, belonging to the technical field of measuring. Background technique [0002] As people pay more and more attention to product quality and product precision, more and more modern industrial and mining enterprises have higher and higher precision requirements for mechanical equipment. This forces the production process of components to not only fully consider the rationality of design and the precision of processing, but also pay attention to the low cost and processing friendliness of products. In actual processing, it is necessary to process various holes or other processing elements on the end face during the processing of large gears, ring gears, and disc-shaped parts. The first prerequisite for the processing of such processing elements is to accurately find the position of the processing elements on the end face, which creates a need for accurate measurement of angl...

AI Technical Summary

Problems solved by technology

For such disc-shaped or ring-shaped parts, most of the current angle measuring devices have a high dependence on the center of the end face of the part during the measurement process, and it is relatively difficult to mark the line. It requires certain measurement techniques and the operation is relatively complicated. For workshop workers In other words, the maintenance capacity is high and the cost is also high.
