Abstract

The design of the vise mechanism in this Tube Notching Device increases capabilities to position the cutting tool relative to the feedstock. This device holds feedstock, centering the feedstock latitudinally and longitudinally to the cutting bit allowing cuts to be reproduced true to each other due to the design of the vise mechanism. Existing tube notching devices allow for the cutting tool to be pivoted relative to the feedstock in one axis, and have vices that only center in one axis. The effectiveness of this tube notching device is increased by the ability of the cutting tool to both translate in one direction and pivot in 2 axes relative to the feedstock, as well as have a vice that can canter feedstock horizontally and vertically. This increased adjustability allows the vise and cutting head to be closer together, which increases safety, operator comfort, and cutting bit life.

A tube notcher with an adjustable and opposable clamping mechanism, comprising of a driven jaw that translates to clamp down on a feedstock to secure it against an opposing jaw wherein the opposing jaw can translate (and subsequently lock) in the same axis as the driven jaw, allowing the location of the centerline of the feedstock to be adjusted along the axis of the driven jaw:

a. Wherein the jaw of claim 1 has four points of contact with the object secured;
b. A profile wherein each jaw (opposable and static) have a 90-degree angle;
c. Wherein each jaw has incremented edges to further secure the feedstock;
d. Wherein the opposing jaw has hardware on opposing sides of feedstock such that 2 or more places are available to clamp the jaw into the frame;
e. Wherein the driven jaw is powered by an ACME thread type screw;
f. Wherein the driven jaw is able to penetrate the frame of the opposing jaw through holes cut into the opposing jaw frame (ref. 301) to allow a broader range of feedstock sizes to be clamped in a relatively small machine;
g. Wherein the driven and opposing jaw faces occupy different planes to allow them to translate past one another to facilitate clamping on a broad variety of feedstock sizes in a relatively small machine.
h. Wherein the handle (303) is removeable to allow greater workplace area.
i. Wherein 120 degrees of over travel allows the device to be fed from one side, ensuring worker safety compared to a machine that must be fed feedstock from multiple directions;
j. Wherein offset adjustment and angle scale increments are milled or laser etched into the frame for longevity of the device;
k. Wherein the opposing jaw in conjunction with offset adjustment allow notches to be made quickly and safely on preexisting bend feedstock.
l. Wherein the driveshaft (305) is outfitted with threads that allow any off the shelf hole saw to be used;
m. Wherein the cutting blade frame (304) is sufficiently long to allow various lengths of hole saws to be interchanged easily and quickly.
