US 2013/0170902 A1 · LINEAR MECHANICAL QUICK-RELEASE FASTENER

Abstract

A linear mechanical quick release fastener is operated by three movements with self-centering chucks and for mounting all types of compatible clamping devices for machining workpieces, especially on automatic precision machine tools. A bottom part has raised locking elements formed integrally in one piece one after another on a plane along a direction at right angles to a clamping direction and base jaws formed integrally in one piece, with a threaded hole for a clamping bolt and a screw element. A top part has recesses, one after another along a direction at right angles to the clamping direction, designed as a counterpiece of the locking elements. One recess is connected at an open front side to a mounting area recessed continuously, which is accessible from the top, and another recess is open on a front side. The top part can receive an upper plane of any compatible clamping device.

Dependent claims

A linear mechanical quick release fastener for locking and unlocking a compatible clamping device on automatic precision machine tools, the fastener comprising:

a bottom part having at least two locking elements formed integrally in one piece one after another and in a raised manner along an axis at right angles to a clamping direction of a self-centering chuck on a plane and two base jaws formed integrally in one piece on a lower plane, a central, continuous threaded opening for receiving a threaded spindle and a threaded hole for receiving a clamping bolt and a screw element (1.8) on a front side of the plane and the lower planes;
and
a top part having a top part lower plane with at least two recesses which are recessed one after another along an axis at right angles to the clamping direction each of the recesses forming a counterpiece for receiving one of the locking elements of the bottom part, wherein one of said recesses is connected on an open front side to a mounting area, which is recessed continuously and is accessible from a top, and another of said recesses is open with a front side at an end of the top part lower plane and has an upper plane, which can receive any compatible clamping device.

A linear mechanical quick release fastener comprising:

a bottom part comprising locking elements extending in a raised manner from a planar surface, one after another along an axis direction, the locking elements being formed integrally in one piece and two base jaws formed integrally in one piece and with a central continuous threaded opening for receiving a threaded spindle and a threaded hole for receiving a clamping bolt, the axis direction being at a right angle to a receiving direction of the threaded opening and the threaded hole and a screw element on a side of the planar surface;
and
a top part on having a top part lower planar surface defining recesses disposed one after another along an axis direction at right angles to the receiving direction of the threaded opening and the threaded hole, each of the recesses forming a counterpiece for receiving one of the locking elements, wherein one of the recesses is connected on an open front side to a mounting area, which is recessed continuously and is accessible from a top, and another of said recesses is open with a front side at an end of lower planar surface and has an upper plane for receiving a clamping device.
