Embodiment Construction

[0024] exist Figure 1 to Figure 4 Among them, it represents the structural composition of the present invention and the connection and positional relationship of parts. The three-dimensional axis of the ball-pin toggle type ball joint includes a ball 1, a ball pin 5, an inner arc-shaped slideway 2, an outer arc-shaped slideway 6, and an X-axis 4. Y-axis 3, Z-axis 9 and pin 11; ball 1 is provided with ball pin 5, Z-axis chute 8 and ball pin hole 14, ball pin 5 is cylindrical, fixedly connected to sphere 1, and Z-axis slides The slot 8 is a transparent square slot, the ball pin hole 14 is a transparent cylindrical hole through the center of the sphere 1, the square slot is perpendicular to the ball pin hole 14; the Z axis 9 is placed vertically, and the upper end of the Z axis 9 is set as the Z axis The slider head 9, the two sides of the Z-axis slider head 9 contact the two sides of the Z-axis chute 8 on the sphere 1 and form a clearance fit; the Z-axis slider head 9 is provid...

Abstract

The invention provides a ball pin pulling type ball joint three-dimensional shaft. According to the ball pin pulling type ball joint three-dimensional shaft, a ball body is provided with a ball pin; a Z shaft, an X shaft and a Y shaft are vertical to one another; the axes of the Z shaft, the X shaft and the Y shaft are crossed to the center of the ball body; a connection end between the X shaft and the ball body and a connection end between the Y shaft and the ball body are respectively and fixedly connected with an inner arc-shaped slide rail and an outer arc-shaped slide rail; the inner arc-shaped slide rail and the outer arc-shaped slide rail are internally provided with slide grooves with the equal width; the inner arc-shaped slide rail can slide on the ball body; the outer arc-shaped slide rail can slide on the inner arc-shaped slide rail; the slide grooves of the outer arc-shaped slide rail and the inner arc-shaped slide rail can be simultaneously sleeved with the ball pin of the ball body; when the ball body rotates, the Z shaft can be directly driven to rotate; meanwhile, the ball pin pulls the slide grooves to drive the outer arc-shaped slide rail and the inner arc-shaped slide rail to rotate so as to drive the X shaft and the Y shaft to rotate; and therefore, one ball joint can drive the three mutually-vertical shafts to rotate. The ball pin pulling type 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 three-dimensional ball joint three-dimensional shaft with ball pins that are driven by ball pins to drive three mutually perpendicular axes to rotate simultaneously. 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 When 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,...
