Abstract
The utility model discloses a rigid positioning device capable of stepless displacement adjustment for a holes-system combined clamp positioning element. The rigid positioning device enables a positioning and supporting element to have unidirectional stepless displacement adjustment on a spatial plane. The utility model is based on the principle that a bevel T-head pin in a base element coincideswith the bevel of a cylindrical pin provided with a bevel at single end, forming constraint fit between the cones, and after being tightened by bolts, such structure can form a rigid structure. The rigid positioning device can realize stepless displacement of the holes-system combined clamp positioning element only through two pairs of adjustment elements. The rigid positioning device is convenient in structural adjustment and high in strength and ensures that the position of the positioning element does not change when the positioning element is under maximum stress strain within the strengthrange of the element.
