AI Technical Summary
During the machining process of bevel gears, factors such as lathe tool wear, CNC operation deviations, and part wobbling can cause deviations in the tooth groove machining, affecting the subsequent meshing precision. Therefore, it is necessary to detect the depth and position of the bevel gear tooth groove with high precision.
Design a bevel gear inspection gauge that utilizes the matching degree between the bevel gear tooth groove mold and the bevel gear tooth groove. By reciprocating lifting and stepping rotation of the bevel gear tooth groove mold, combined with a pressure sensor, the opening accuracy of the bevel gear tooth groove is detected. The depth and position of the tooth groove are determined by the pressure value difference.
This technology enables high-precision detection of bevel gear tooth grooves, ensuring the meshing precision of bevel gears and improving the machining quality of bevel gears.
