Three-axis displacement platform, has support frame with one side superposed on linear device to move with device to perform Y-axial displacement, and balance weight located on support frame for balancing weight

摘要

The platform has a support frame (30) with one side superposed on an axis linear device (20) to move with the device to perform a Y-axial displacement. Another axis linear device (40) provides a Z-axial displacement, where the device (40) is superposed on another side of the support frame to move with the device (40) to perform the Y-axial displacement. Moving direction of the linear device (40) is made to intersect with the moving directions of a third axis linear device (10) and the linear device (20). A balance weight (50) is located on the support frame for balancing weight.
