ABSTRACT:
A clamping device & method for down clamping against a workpiece by utilizing part features produced during a prior operation. The mechanics of this device allow it to open, close, raise and lower during its initialization and release. The device contains a built in block type jaw restraint to facilitate the customization of its clamping heads to suit the shape of the part feature it is to clamp down upon. This device is used within the part boundaries, thus facilitating higher quantity part batch sizes being presented to the limited travels of the machine tool used to process the parts. This invention is comprised of readily available hardware items along with two cost effective and simple to mass-produce components. The device can be actuated manually or with automatic actuation. The method described to prepare the project is unique to the function & usage of this invention.
