摘要

center mount according to an embodiment of the present invention, the workpiece is detachable ball body part that is not what ball ball and socket assembly; Mounted on the measuring table, the base part is loaded, the body portion top surface; The parts of the body such that the body portion is pressed against the base portion, the pressing force transmission part having a movable lifting in the height direction interlocking member relative to the base portion; And is coupled to the base unit, using a lead screw principle elevating the case by regulating the height of the vertical link member by the rotation operation by the pressing force control unit for controlling the pressing force of the pressing member relative to the body portion; may include. According to an embodiment of the invention, the lead screw to accurately position the body portion by the pressing force adjustment portion is provided with a simple rotation operation type, while it can improve the measurement reliability of the measurement error and so on can be securely positioned, also in comparison with the conventional it is possible to reduce the manufacturing cost by having a simple structure. ;
