| Abstract: | Based on the forming and movement characteristics of the spherical helical curved surface, using the differential geometry to describe and establish mathematical model of the spherical spiral curve and the spherical helical curved surface on the sphere. Put forward a kind of slipper type spherical helical pair of spherical helical surface meshing with slider, research on the meshing surface friction and the self-locking feature, and design a kind of clamping mechanism using this spherical helicoid vice. The results show that the mechanism is compact, flexible safe and reliable, and can clamp a variety of objects of different sizes accurately and reliably. |
