Abstract
The present invention relates to a chuck for gripping workpieces having an outer chuck body rotatable about a chuck axis and defining a cavity. The chuck includes a collar, coupled to the outer chuck body, having a slot with a slot axis angled relative to said chuck axis. An inner chuck body located within the cavity is movable along the chuck axis relative to the collar and the outer chuck body. The inner chuck body includes a bore having a bore axis angled relative to said chuck axis into which the jaw rod is disposed, with the jaw rod being coupled to the collar.
Claims13
A chuck for holding a workpiece comprising:
- an outer chuck body having a chuck axis and defining a cavity;
- a collar coupled to said outer chuck body and including a slot having a slot axis angled relative to said chuck axis;
- an inner chuck body located within said cavity and movable along said chuck axis relative to said collar and outer chuck body, said inner chuck body including a bore having a bore axis angled relative to said chuck axis;
- and
- a jaw rod disposed in said bore and coupled to said collar.
A chuck and a workpiece assembly comprising:
- a workpiece;
- a chuck having jaws coupling said workpiece to said chuck, said chuck including:
- an outer body having a cavity and a chuck axis;
- an inner body having at least two bores each having a bore axis angled relative each other, said inner body movable between an extended inner body position and a retracted inner body position along said chuck axis and within said cavity;
- a collar positioned between said outer body and said inner body, said collar including at least two key slots, each having a slot axis;
- at least two jaw rods disposed in said bores and movable between a retracted jaw position and an extended jaw position, said jaw rods including said jaw and a coupling member, said coupling members being coupled to said slots for movement along said slot axes;
- wherein as said inner body moves from said extended inner body position to said retracted inner body position, said jaws move from said extended jaw position to said retracted jaw position to couple said workpiece to said chuck.
