Abstract
An assembly according to some embodiments of the disclosure includes a punch and a clamping assembly. The punch includes a body having a front end and a rear end. The front end has a cutting edge. A passageway extends through the body and a counterbore is provided proximate to a second end of the body. The clamping assembly includes first and second jaws pivotally attached to each other. Each jaw includes a main body having a nose extending from a front surface thereof. The nose has an outer surface which has a diameter which is smaller than the outer diameter of the main body. When the clamping assembly is mated with the punch, the noses seat within the counterbore, and the front surfaces of the main bodies engage against the rear end of the body of the punch.
Claims20
An assembly comprising:
- a punch including a body having a front end and a rear end, said front end having an edge therein which can be used to cut an associated workpiece, a passageway having a predetermined diameter extending through said body from said front end to said rear end, said passageway having a counterbore which is proximate to said second end of said body;
- and
- first and second jaws pivotally attached to each other around a pivot, each said jaw comprising a main body having an outer surface, an opposite inner surface and a front surface extending between said outer and inner surfaces, and a nose extending from said front surface, said nose having an outer surface, an inner surface and a front surface extending between said outer and inner surfaces of said nose, said outer surface of said nose having a diameter which is smaller than the outer diameter of said main body,
- wherein, in use and when said jaws are mated with the punch, said noses seat within said counterbore, and said front surfaces of said main bodies engage against the rear end of the body of the punch.
The assembly of claim 7, further comprising a draw stud having a plurality of alternating grooves and lands formed on an exterior surface thereof, said alternating grooves and lands on said noses and said main bodies meshing with said alternating grooves and lands on the draw stud.
A clamping assembly for clamping a draw stud, said clamping assembly comprising:
- first and second jaws pivotally attached to each other around a pivot;
- said first jaw comprising a main body having an outer surface, an opposite inner surface and a front surface extending between said outer and inner surfaces, and a nose extending from said front surface, said nose having an outer surface, an inner surface and a front surface extending between said outer and inner surfaces of said nose, said outer surface of said nose having a diameter which is smaller than the outer diameter of said main body;
- said second jaw comprising a main body having an outer surface, an opposite inner surface and a front surface extending between said outer and inner surfaces, and a nose extending from said front surface of said second jaw, said nose of said second jaw having an outer surface, an inner surface and a front surface extending between said outer and inner surfaces of said nose, said outer surface of said nose of said second jaw having a diameter which is smaller than the outer diameter of said main body of said second jaw;
- and
- a spring provided between said first and second jaws, said spring biasing said jaws into a closed position.
