Abstract

The invention discloses an automatic assembling device and method for a large-length-diameter-ratio shaft and a hole, and relates to the technical field of assembling of workpieces of large-length-diameter-ratio shafts and holes. By adopting a clamping assembly capable of adjusting the position and angle of a workpiece with the hole, a posture adjusting mechanism capable of adjusting the position and posture of the shaft workpiece (shaft), and a first lifting assembly and a second lifting assembly which are capable of adjusting the vertical position of the posture adjusting mechanism and the testing position of a measuring assembly respectively, a posture vector Am of a local area of the shaft workpiece and a posture vector A1 of the hole can be measured, so that the shaft workpiece posture adjusting amount deltaAm which needs to be executed by the posture adjusting mechanism is acquired; and real-time adjustment can be conducted in the assembling process of the shaft workpiece and the workpiece with the hole, so that it is guaranteed that the shaft workpiece does not make contact with the inner wall of the hole of the workpiece with the hole, thus the situations of interference and shaft workpiece damage are avoided, and the assembling quality and efficiency are improved.

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 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 pr...
