Abstract

The invention provides a ball joint three-dimensional shaft. The ball joint three-dimensional shaft comprises a ball body, a slide block, a movable slide rail, slide strips, an X shaft, a Y shaft, a Z shaft and a pin, wherein the ball body is provided with a Z shaft slide groove and an XY shaft slide groove vertical to the Z shaft slide groove; and the ball body and the Z shaft can rotate relatively around the pin. The Z shaft, the X shaft and the Y shaft are vertical to one another; the X shaft and the Y shaft are placed horizontally and can only rotate around respective axes; the slide strips are fixedly connected with a connection end between the X shaft and the ball body and a connection end between the Y shaft and the ball body; the movable slide rail is internally provided with an arc-shaped slide groove; the two side faces of the slide strips are contacted with the two side faces of the arc-shaped slide groove to form clearance fit; the slide strips slide in the arc-shaped slide groove; the two side faces of the slide block are contacted with the two side faces of the XY shaft slide groove on the ball body to form the clearance fit; and the slide block can slide in the XY shaft slide groove. According to the ball joint three-dimensional shaft, one ball joint is rotated to drive the three mutually-vertical shafts to rotate so as to immediately and accurately decompose a space corner to each vertical shaft and realize the effect of converting a space three-dimensional corner into a plane two-dimensional corner. The ball joint three-dimensional shaft is simple in structure and ingenious in mechanism and has stronger practical value.

Description

technical field [0001] The invention relates to a ball joint transmission mechanism, in particular to a ball joint three-dimensional shaft in which three mutually perpendicular axes rotate simultaneously through the rotation of the ball joint. Background technique [0002] In the mechanical transmission mechanism, the universal joint is a common mechanism that connects two shafts to achieve coaxial or different shaft transmission, but the universal joint cannot be used in the occasion where the two shafts are perpendicular, let alone the In the case of connecting three mutually perpendicular axes. In practical applications, there are many occasions where one joint rotation is required to simultaneously drive three mutually perpendicular axes to rotate at the same time. The problem of angle decomposition of space Cartesian coordinate system, the problem of projection transformation of space straight line and plane to three projection planes in mechanical drawing, etc. Adopt...
