摘要： PURPOSE: To obtain a highly accurate clamping device that stands long use by making a holding member that holds the work freely shakable and movable vertically when the work is moved and positioned.
CONSTITUTION: A workpiece W is held between a lower clamping jaw 111 and an upper clamping jaw 117. When the tip of the lower jaw member 95 is thrusted upward, it shakes upward around a spherical bearing 101, compresses a spring 133 and pushes up a balance plate 81. Consequently, a vertical slide 77 goes up, the base of the lower jaw member 95 is lifted up and the lower jaw member 95 quickly becomes horizontal. When the lower jaw member 95 is thrusted downward, a guide rod 135 is pulled downward. The balance plate 81 goes down and the vertical slide 77 goes down. Consequently, the lower jaw member 95 becomes horizontal quickly. By this way, vertical force can be absorbed by vertical movement.
