Mechanism capable of implementing six-degree-of-freedom adjustment of large workpieces

Abstract

The invention belongs to the technical field of mechanical engineering, particularly relates to a mechanism capable of implementing six-degree-of-freedom adjustment of large workpieces, and aims to solve the problem of posture adjustment interference in an assembling process of large revolving parts. The mechanism comprises two single-bracket assemblies, wherein the two single-bracket assemblies are mounted side by side; an adjusted part (5) is mounted on the upper parts of the two single-bracket assemblies; the rear single-bracket assembly is a driving bracket; the front single-bracket assembly is a follow-up bracket; the two single-bracket assemblies are five-degree-of-freedom brackets; and five degrees of freedom comprise three translation degrees of freedom, a rotational degree of freedom and a follow-up rotational degree of freedom. The five-degree-of-freedom single-bracket assemblies are adopted, unlimited six-degree-of-freedom adjustment is realized, and the mechanism can implement six-degree-of-freedom unlimited adjustment on parts of which the diameters are 1.5 m, the lengths are 10 m and the weights are 2 t. An adjustment process is flexible, and clamping stagnation is avoided. Adjustment angle interference in a posture adjustment process of the parts is avoided effectively, and the parts are protected against being damaged.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a mechanism capable of realizing the six-degree-of-freedom adjustment of a large workpiece. Background technique [0002] In the field of production and manufacturing of large-scale mechanical products, parts adjustment mechanisms are often used in the process of component assembly. There are many mechanisms that can achieve six-degree-of-freedom adjustment, such as the combination of linear guide rails and rotary guide rails, stacking three linear guide rails, and then combining three rotary guide rails to complete three translations and three translations. Combination of rotary motions. But in some special occasions, such as the pose adjustment of large and heavy parts, this method has low reliability, the risk of overturning, and there are great difficulties in the way of realization. [0003] At present, in the assembly process of large rotary par...
