BALL SCREW CLAMP DEVICE
Document Type and Number:
Japanese Patent JPH10156609
Kind Code:
A
Abstract:
To provide a clamp screw wherein a loss of clamp force is markedly reduced, strong clamp force by a small rotary input, sufficient clamp force by manual operation, and sufficient clamp force without an excessive clamp by effectively utilizing opposite thrust force of a rotary tool can be obtained.
By a clamp screw 110, when into contact with an object 142 mounting a flange ring 118, a member 111 with screw, stopping its rotation, is advanced into a clamp condition. Rotation of an operating ring 112 is screw fed by a ball 1l3 moved around a screw groove, as a result, a pressure is applied to a flange ring through a lock ring 116, the mounted tool 142 is clamped.
