Abstract

The invention relates to a five-degree-of-freedom redundant driving parallel mechanism with a large turning angle. The mechanism comprises a fixed platform, an articulated moving platform, and a rotating mechanism; the fixed platform and the articulated moving platform are connected with each other through first, second, fifth and sixth driving branch chains; the fixed platform and the rotating mechanism are connected through third and fourth driving branch chains; the first, second, five, and sixth driving branch chains can drive the articulated moving platform to flip back and forth and translate left and right; and the linkage between the first, second, five, and sixth driving branch chains and the third and fourth driving branch chains can drive the articulated moving platform to moveup and down, rotate horizontally, and flip left and right. The mechanism has strong adjustment ability, large turning angle and high flexibility, and can perform local processing of super large and complex curved surfaces.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and is especially suitable for the processing of local complex free-form surfaces of super-large workpieces. The mechanism is a five-axis parallel processing head with high rigidity and high precision. Background technique [0002] The rocket carrying capacity is an important symbol to measure a country's comprehensive strength and technological level. In the future, the diameter of the heavy-duty launch vehicle tank will be nearly ten meters, and the total length will be nearly 100 meters. The structure of the heavy-duty rocket tank belongs to the category of super large workpieces. The box has the characteristics of oversized workpiece, thin and easy-to-deform shell, and convex and complex surface structure. However, Tricept and Exechon robots currently use a one-shift, two-rotation, three-degree-of-freedom parallel mechanism to connect two-degree-of-freedom rotating heads in series. Cha...
