Embodiment Construction
[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0047] As shown in Figures 1-7, a phantom motion platform of the present invention includes a motion device, a stepping motor driver and a control device. The FFB type ball screw pair, and the linear rolling guide rail pair and the ball screw pair both adopt preload, which eliminates the gap, improves the contact stiffness and positioning accuracy, and is driven by a stepping motor under the control of the numerical control system. The linkage of the coordinate CNC worktable can realize any curved motion trajectory in the plane, and can realize gapless motion. It has the characteristics of high precision, high efficiency, long life, small wear, simple and practical. There are X-direction stepping motors and Y-direction stepping motors respectively connected to the X-direction and Y-direction of the precision CNC workbench. The stepping motor adopts 57BY...
