摘要
PURPOSE: A screw jack type 4-directional motion base apparatus is provided to convert the location of parallel link to left and right, and up and down by using a screw jack, and to able to 4-directionally move by installing two or more diving bodies. CONSTITUTION: A crank type 4-directional motion base apparatus comprises an upper base(11), a lower base(12), a first and a second driving bodies(13,14), and a driving assistant(16). The first and the second driving bodies comprise a lower bracket, a screw, a parallel ling and an upper bracket. The lower bracket is mounted to the lower base, and a lower part of the parallel ling is mounted on the lower bracket. The screw conducts a rotary motion according to a driving force of a motor. The parallel link forms a parallelogram by four links linked by a first to a fourth link bars. The upper bracket is mounted on an upper part of the parallel link, connected to the upper base. The driving assistant is linked with an up and down motion of one or more driving bodies.
