Abstract
A machine vise has incorporated into it a pair of collet jaws that allows for the machining of top surfaces and ends of a held part. The collet jaws are secured to each of the clamping blocks on the machine vise. The collet jaws include at least one collet pocket shaped into the inside surface of each collet jaw. The collet pockets are designed to receive collet pads which are shaped to hold a generally cylindrical part with varying diameters. By having more than one collet pocket within each collet jaw, several different sizes of collet pads can be utilized at the same time and a part with varying diameters can be held securely in place within the machine vise.
Claims16
A clamping mechanism for holding a multi-diameter part, comprising:
- a) a clamping base including:
- i) an integrated tightening mechanism and
- ii) first and second clamping blocks positioned opposite and parallel to each other, said first and second clamping blocks having inside and outside surfaces, said first clamping block being attached to said tightening mechanism and said second clamping block being attached to said base;
- b) first and second collet jaws, said first and second collet jaws each having an inside surface and an outside surface, said outside surface of said first collet jaw reversibly secured to said inside surface of said first clamping block and said outside surface of said second collet jaw reversibly secured to said inside surface of said second clamping block, said first and second collet jaws each including:
- i) at least a pair of collet pockets formed on said inside surface of each collet jaw, each collet pocket shaped to receive a collet pad and
- ii) means for securing said collet jaw to said clamping blocks;
- and
- c) at least a pair of collet pads reversibly secured to each said collet jaw, a shape of said collet pads essentially forming an arc of a hollow tube, said collet pads having an outside radius and an inside radius, said outside radius being such that said collet pad will accurately fit into said at least one collet pocket, said inside radius being substantially equal to a proximate radius of the part being held in place.
A pair of substantially identical collet jaws for attachment to the clamping block of a machine vise, with each collet jaw designed to receive at least a pair of varying sized and shaped collet pads for securing parts with non-uniform cross sections, each collet jaw having an inside surface and an outside surface and comprising:
- a) at least a pair of collet pockets formed on the inside surface of each collet jaw, each said collet pocket shaped to receive a collet pad and
- b) means for securing the collet jaw to the machine vise clamping block.
A clamping mechanism for holding a part, comprising:
- a) a clamping means including:
- i) an integrated tightening mechanism and
- ii) a plurality of clamping blocks surrounding a central axis, said plurality of clamping blocks having inside and outside surfaces, said plurality of clamping blocks being attached to said integrated tightening mechanism;
- b) a plurality of collet jaws with each collet jaw within said plurality of collet jaws having an inside surface and an outside surface, said outside surface of each said collet jaws reversibly secured to said inside surface of one of said clamping blocks and said outside surface of each of said plurality of collet jaws reversibly secured to said inside surface of one of said plurality of clamping blocks, each of said collet jaws each including:
- i) at least a pair of collet pockets formed on said inside surface of each of said collet jaws, each collet pocket shaped to receive a collet pad and
- ii) means for securing each said collet jaw to each of said clamping blocks;
- and
- c) at least a pair of collet pads reversibly secured to each of said collet jaws, a shape of each said collet pad essentially forming an arc of a hollow tube, each said collet pad having an outside radius and an inside surface, said outside radius being such that said collet pad will accurately fit into said at least one collet pocket, said inside surface being suitably formed to hold the part being held in place.
