Gear tooth profile measuring device based on line structured light

Abstract

The invention discloses gear tooth profile measuring equipment based on linear structured light. The gear tooth profile measuring equipment comprises a workbench, a gear fixing base installed on the workbench and an annular guide rail arranged around the gear fixing base. The annular guide rail is provided with two camera mounting tables which can slide along the annular guide rail and drive the cameras to rotate at the same time, the cameras are arranged on the camera mounting tables, an annular laser device is arranged above the gear fixing base, and the annular laser device is concentric with the central axis of a measured gear fixed to the gear fixing base. Projection light on measured gear teeth can be prevented from being shielded by a previous gear tooth surface by adopting the circular laser, measurement of various parameters such as gear tooth thickness, base circle radius and involute tooth profile error can be completed by adopting the epicyclic and autorotation integrated image acquisition device, and the gear tooth profile measurement device has the characteristics of high measurement efficiency, high precision, small size and the like, and can meet gear measurement of different sizes and tooth numbers.

Description

technical field [0001] The invention relates to a gear tooth profile measuring device based on line structured light. Background technique [0002] Gear transmission is one of the important forms of mechanical transmission. It has the characteristics of good stability, accurate transmission ratio, high efficiency, and long life. Gears are widely used in machinery manufacturing, aerospace, and precision instruments. With the design and manufacture of gears The level of requirements is getting higher and higher, and the measurement of gears is also more stringent. Therefore, the research and design of more precise, efficient and practical gear measuring equipment is of great significance and role in improving the level of gear manufacturing. [0003] Structured light vision technology is a main method of non-contact measurement technology. Its principle is to project structured light to the measured object, and reconstruct the three-dimensional information of the measured obj...
