Analytical mechanism for ball pin poking space fixed point rotating angle freedom degree

Abstract

An analytical mechanism for a ball pin poking space fixed point rotating angle freedom degree comprises a ball, a ball pin, an inner arc slide way, an outer arc slide way, an X shaft, a Y shaft, a Z shaft, an X shaft disc, a Y shaft disc and a Z shaft disc. The ball pin is arranged on the ball, the ball is connected with the Z shaft through a pin, and the X shaft and the Y shaft are fixedly connected with the inner arc slide way and the outer arc slide way respectively; the inner arc slide way and the outer arc slide way are respectively provided with a sliding groove, the ball pin of the ball is sleeved by the sliding grooves simultaneously, when the ball rotates, and the ball pin pokes the outer arc slide way and the inner arc slide way to rotate so that the ball can drive the X shaft, the Y shaft and the Z shaft to rotate correspondingly. Angle scales are arranged on the spherical surface, the inner arc slide way and the outer arc slide way to display the rotating angle of a ball joint relative to the three shafts, angle scales are arranged on the X shaft disc, the Y shaft disc and the Z shaft disc, and the rotating angles of the three shafts are displayed through pointers on the three shafts. The analytical mechanism solves the problem of converting the space three-dimensional rotating angle into a planar two-dimensional rotating angle.

Description

technical field [0001] The invention relates to a space-fixed-point rotation degree of freedom demonstration device, in particular to a ball-pin toggle type space-fixed-point rotation angle degree of freedom analysis mechanism which is driven by the rotation of a ball joint to simultaneously rotate three mutually perpendicular axes. Background technique [0002] In the mechanical principle, the motion of a point in space has three translational degrees of freedom in mutually perpendicular directions and three rotational degrees of freedom in mutually perpendicular directions. At present, there is no application where the spatial fixed-point rotation drives three mutually perpendicular axes to rotate at the same time, and there is no application example where the spatial fixed-point rotation angle is decomposed into three mutually perpendicular axes and plane angles. In many practical applications, it is necessary to rotate a joint to simultaneously drive three mutually perpe...
