Abstract
The four-bar linkage and stressed lap had an outstanding result on grinding and polishing axisymmetrical asphere[1]. Its mechanical structure is succinct and direct, and control is also easy. In "Mathematical analysis about deformation and movement feature, when using stressed lap to off-axis segment" [2] (following using MADMF to represent it in this paper), author put forward two mechanical structures to achieve the axis of lap tilting on both X and Y directions, and overlap with normal line of off-axis segment's contacting point, both structures have a lower universal coupling and 3 pairs of hoisting joints. Based on adopting four-bar linkage to off-axis segment, now we put forward a new mechanical structure, and analyze the movement feature. On the other hand, we analyze the movement feature of four-bar linkage, and remind the attentive matters when using this structure to mirror.
