| 摘要 |
The present invention relates to an apparatus for holding a material at multiple-axis positions, including a base block; a vertical-axis rotary block penetrating the base block in a vertical direction and engaged thereto to be able to rotate around a vertical center axis, and having a brake plate on an outer periphery surface at a point located above the top surface of the base block; a seating table configured to support the target material and fixed to an upper end of the vertical-axis rotary block; a braking block fixed to the base block to enclose the point provided with the braking plate on the outer peripheral surface of the vertical-axis rotary block, and having a fixing pad at a point corresponding to the top surface of the braking plate and a lifting pad positioned at a point corresponding to the fixing pad, of a lower portion of the braking plate in a lifting structure; an operation block seated on the top surface of the base block to be positioned below the lifting pad and having an inner space in a portion corresponding to the lifting pad; and a fluid supply unit for supplying a pressurized fluid to a fluid port formed at a portion, where the inner space of the operation block is positioned, of the base block so that the lifting portion is pushed and lifted by the operation block, thereby compressing the braking plate between the lifting pad and the fixing pad. |
