The present invention relates to the field of automatic measurement of the hole positions of industrial annular parts, and provides a convenient automatic circumferential hole finding and automatic hole center alignment detection method and device, which are used for the automated assembly of a certain large precision part in aerospace. During measurement, the annular part is first automatically aligned, and the XYZ axis of the four-coordinate truss robot is moved to align the rotation center of the measuring end with the center of the annular part. The sensor is then moved to the radial position of the hole position to be measured by the radial cylinder. The Z axis is slowly moved downward to the measuring plane. When the value of the optical fiber sensor is higher than the threshold value 1, the predetermined detection height is reached, and the movement of the Z axis is stopped. The rotating R axis drives the digital optical fiber sensor to rotate one circle. Through the change in the value of the optical fiber sensor, the circumferential scanning hole finding and hole center positioning of the small blind hole of the annular part are realized with the value below the threshold value 2 as the standard. The present invention adopts a non-contact measurement method to avoid scratches and bumps on precision parts to the greatest extent.

This invention discloses a method for anti-jamming shaft hole assembly based on visual-tactile perception for unknown hand posture. One visual-tactile sensor with and without anchor points are installed on the robot gripper. The orientation of the main axis of the gripped shaft is calculated using the visual-tactile image without anchor points, and the gripper posture is adjusted to achieve pre-alignment before insertion. To correct insertion failures caused by shaft posture estimation errors, the visual-tactile image with anchor points is used to extract low-latency relative force feedback in real time through a dual-mask spatial averaging algorithm. This guides a helical search based on force-potential hybrid admittance control to establish a stable contact state, achieving tactile-guided hole finding. Finally, for shafts with complex surface textures that experience jamming due to abrupt friction changes, a bidirectional escape mechanism involving inward and outward contraction along the helical normal direction is employed to release contact constraints, achieving compliant insertion guided by tactile perception. This invention achieves visual-tactile insertion operation in situations where there are no wrist force sensors and the initial posture of the shaft within the gripper is unknown, significantly improving the assembly success rate and robustness in complex working conditions.
