A one way clamp mechanism C is composed of a clamping section 7 provided with a clamp pawl 10 and a locking section 8 in which an outer guide 22 of the clamping section 7 is slidably provided on a smaller diameter section 31 of the locking section 8. The one way clamp mechanism C is also composed of an inclined plane 28 provided on the outer guide 22, a lock ball 33 housed in a long opening 32 of a small diameter section 31, and a first spring 34. The lock ball 33 is biased to move in a locking direction (shown by the arrow A) by the first spring 34 and the clamping section 7 is biased to move in a locking direction by a second spring 37.
Claims13
A clamping device having a clamping section for clamping a workpiece movably provided on a cylindrical guide shaft along the axis of the guide shaft, wherein the clamping section and a locking section are each provided to make a pair at ends of the guide shaft and the locking section is fixedly secured to the clamping section in position on the guide shaft and is provided to move in a locking direction and in an unlocking direction on the guide shaft and forms a one way mechanism whereby when the locking section is moved in the locking direction, the locking section prevents movement of the clamping section only in an unclamping direction relative to the workpiece and when the locking section is moved in the unlocking direction, the locking section makes the movement of the clamping section free.
A clamping device mounted on a workbench, the clamping device comprising:
- a base fixedly secured to the workbench;
- a rotating table rotatably supported by the base;
- a supporting platform fixedly secured on the rotating table;
- a guide shaft which is secured to the supporting platform;
- and
- a clamping section and a locking section, each provided to make a pair on ends of the guide shaft in the axial direction.
