Abstract

The invention discloses a large aspect ratio shaft hole automatic assembly device and method, and relates to the technical field of large aspect ratio shaft hole workpiece assembly. The posture adjustment mechanism for position and attitude, as well as the first lifting assembly and the second lifting assembly that can respectively adjust the vertical position of the attitude adjustment mechanism and the test position of the measurement assembly, can measure the position and attitude vector Am of the local area of ​​the workpiece and the hole Pose vector A1, so as to obtain the shaft workpiece pose adjustment amount △Am that the attitude adjustment mechanism needs to perform; the shaft workpiece can be adjusted in real time during the assembly process with the hole workpiece, so as to ensure the hole between the shaft workpiece and the hole workpiece. The inner walls are not in contact to avoid interference and damage to the shaft workpiece and improve assembly quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of workpiece assembly with large aspect ratio shaft holes, in particular to an automatic assembly device and method for large aspect ratio shaft holes. Background technique [0002] Shaft hole assembly is a common assembly method in the field of machinery manufacturing. With the development of the field of machinery manufacturing towards ultrasonic high-precision and high-quality manufacturing, the accuracy and quality requirements of shaft hole assembly continue to improve. [0003] For slender shafts with a large aspect ratio (usually the ratio of length to diameter is greater than 100), due to the poor rigidity of the slender structure, the manufacturing and processing accuracy is usually low, and there are large radial deformation and deformation during the manufacturing and storage process. The problem of random directions brings great difficulties to the assembly of the shaft hole. During the assembly ...
