Embodiment 1
[0019] Embodiment 1: as image 3 As shown, the linear drive four-degree-of-freedom hybrid manipulator of the present invention is used as a module, which is placed on the lead screw structure through a threaded connection structure to make it move in the horizontal direction.
Embodiment 2
[0020] Embodiment 2: as Figure 4 As shown, borrowing the principle of the traditional radial drilling machine, the linear drive four-degree-of-freedom hybrid manipulator of the present invention is fixed on the column so that it can rotate around the axis of the column.
Embodiment 3
[0021] Embodiment 3: as Figure 5 As shown, borrowing the principle of a vertical machine tool, the linear drive four-degree-of-freedom hybrid manipulator of the present invention is placed on the screw structure as a module to make it move vertically.
[0022] The linear-driven four-degree-of-freedom hybrid manipulator of the present invention is driven by a linear motor, and can realize motions with high speed, high positioning accuracy and repeatable positioning accuracy; , to effectively generate the advantageous feed direction or expand the working range, and overcome the shortcomings of the small working space and limited posture of the general parallel or series manipulator.
