AI Technical Summary
Existing technologies for multi-view measurement of small module gears suffer from spatial deviations between the gear mounting axis, mandrel axis, and the actual rotation axis of the turntable due to factors such as clamping eccentricity, clamping posture error, and turntable rotation error. These deviations affect the accuracy and reliability of tooth surface reconstruction and lack effective methods for extracting tooth surface regions.
A gear pose adjustment module and a multi-view measurement module are used. A mandrel coaxial with the gear under test is set in the gear pose adjustment module, and the reference cylindrical section on the mandrel is used as the rotation reference calibration carrier. The original tooth surface and mandrel point cloud data are obtained by combining the multi-degree-of-freedom adjustment bracket. The real rotation axis is calibrated by the control and calculation module, a unified rotation coordinate system is established, installation structure points and noise points are eliminated, and the tooth surface is reconstructed.
It effectively eliminates the reference deviation caused by clamping eccentricity and mandrel installation errors, improves the accuracy and reliability of tooth surface reconstruction, and provides high-quality three-dimensional structural data, laying the foundation for subsequent gear morphology analysis and quality evaluation.
