Abstract
A coaxial collect truck is disclosed having at least two clamping jaws which are radially adjustable by a respective chuck lever, whereby every chuck lever is connected to a respective stationary base part at one end by a first spring joint and is connected to a set collar at its other end by a second spring joint. The set collar is capable of engaging and releasing the clamping jaws by being rotatably seated at the base part by a respective third spring joint. Coaxial clamping in the sub-micrometer range is thereby achieved for precision round parts, particularly of plug pins for the releasable connection of optical fibers of light waveguides, whereby all chuck levers, base parts, first, second and third spring joints as well as the set collar are fashioned of one piece from a common plate.
Claims12
In a coaxial collet chuck having at least two clamping jaws adjustable and moveable in common in a radial direction, and means for moving the jaws radially, the improvement comprising:
- said means including a separate chuck lever (Sh) connected to each of said clamping jaws (Sb) at a point intermediate the ends of each of said chuck levers (Sh);
- said chuck levers (Sh) each being connected to a respective stationary base part (Bt) by a first spring joint (Fg1) on a first end of each of said chuck levers;
- said chuck levers (Sh) each being hinged to a set collar (Sr) by a second spring joint (Fg2) for common clamping and releasing of said clamping jaws (Sb) on a second end of each of said chuck levers opposite said first end;
- said set collar (Sr) being respectively rotatably seated at each of said stationary base parts (Bt) by a third spring joint (Fg3);
- whereby all of said chuck levers (Sh), stationary base parts (Bt), first, second and third spring joints (Fg1, Fg2, Fg3) as well as said set collar (Sr) are fashioned of one piece from a common plate.
