Abstract

Device and methods comprising a clamping device or vise which applies stabilizing force to a workpiece for a machining, operation using an adjustable stock engagement point, the stock engagement point being adjustable by inserting shims or spacers between the stock engagement surface (e.g., a gripper wall and the body of the device).

Claims

1. A clamp comprising:

a main body comprising an attachment surface having at least one main body bore therein sized and shaped to accept a fastener;

a gripping member comprising an exterior surface and an opposing interior surface having at least one gripping member bore therethrough sized and shaped to receive said fastener and disposed such that, when said gripping member is assembled with said main body said at least one gripping member bore is generally coaxial with said at least one main body bore;

at least one spacer having at least one spacer bore therethrough sized and shaped to receive said fastener and disposed such that, when said gripping member is assembled with said main body and said at least one spacer is disposed therebetween, said at least one spacer bore, said at least one gripping member bore, and said at least one main body bore are generally coaxial.

2. The clamp as claimed in claim 1, wherein the height and width of said attachment surface is generally equal to the height and width of said gripping member.

3. The clamp as claimed in claim 1, wherein said first fastener is threaded and said main body bore is threaded, and said threading is configured such that said threaded main body bore can receive said threaded first fastener.

4. The clamp as claimed in claim 1, wherein the height and width of said at least one spacer is generally equal to the height and width of said gripping member.

5. The clamp as claimed in claim 1, wherein said number of bores is two.

6. The clamp as claimed in claim 1, wherein said at least one spacer comprises a plurality of spacers.

7. A clamp comprising:

a main body generally in the configuration of a rectangular prism and comprising;

a top and an opposing bottom with a main body bore extending therethrough and sized and shaped to accept a first fastener;

an attachment side adjacent and generally perpendicular to said top and said bottom side having disposed thereon a number of bore holes, each bore hole in said number of bore holes being sized and shaped to accept a second listener;

a gripping member generally in the configuration of a rectangular prism and comprising;

an exterior stock engagement surface and an opposing interior surface;

a number of through bores equal to said number of bore holes in said attachment side, each one of said through bores being disposed through said gripping member such that said each one of said through bores is generally coaxial with a bore hole in said attachment side, and each one of said through bores being sized and shaped to accept said second fastener;

at least one spacer generally in the configuration of a rectangular prism and having a number of spacer through bores equal to said number of bore holes in said attachment side, each one of said spacer through bores being disposed through said at least one spacer such that said each one of said spacer through bores is generally coaxial with a bore hole in said number of bore holes in said attachment side, and each one of said spacer through bores being sized and shaped to accept said second fastener.

8. The clamp as claimed in claim 7, wherein the height and width of said attachment side is generally equal to the height and width of said gripping member.

9. The clamp as claimed in claim 7, wherein said first listener is threaded and said main body bore is threaded, and said threading is configured such that said threaded main body bore can receive said threaded first fastener.

10. The clamp as claimed in claim 7, wherein the height and width of said at least one spacer is generally equal to the height and width of said gripping member.

11. The clamp as claimed in claim 7, wherein said number of bore holes is two.

12. The clamp as claimed in claim 7, wherein said at least one spacer comprises a plurality of spacers.

13. A clamp comprising:

a main body generally in the configuration of a rectangular prism and comprising;

a top and an opposing bottom with a main body bore extending therethrough and sized and shaped to accept a first fastener;

an attachment side adjacent and generally perpendicular to said top and said bottom side having disposed thereon a number of bore holes, and a back side opposing said attachment side, said back side having a recessed channel sized and shaped to accommodate an O-ring;

a first lateral side extending between said attachment side and said back side and an opposing second lateral side, said first lateral side and said second lateral side each having a recessed channel sized and shaped to accommodate said O-ring and disposed on said first lateral side and said second lateral side continuously with said back side channel;

a gripping member generally in the configuration of a rectangular prism and comprising;

an exterior stock engagement surface having a recessed channel sized and shaped to accommodate said O-ring;

an interior surface opposing said exterior stock engagement surface and having disposed generally perpendicularly thereon a number of attachment pegs equal to said number of bore holes in said attachment side, each one of said attachment pegs being disposed on said gripping member such that said each one of said attachment pegs is generally coaxial with a corresponding bore hole in said attachment side, and each one of said attachment pegs is sized and shaped to be received by said corresponding bore hole;

a plurality of opposing lateral sides extending between said exterior stock engagement surface and said interior surface, each of said apposing lateral sides having a recessed channel sized and shaped to accommodate said O-ring and disposed continuously with said stock engagement surface channel;

at least one spacer generally in the configuration of a rectangular prism and having disposed therethrough a number of spacer through bores equal to said number of bore holes in said attachment side, each one of said spacer through bores being disposed through said at least one spacer such that said each one of said spacer through bores is generally coaxial with a corresponding bore hole in said attachment side, and each one of said spacer through bolts being sized and shaped to accept a corresponding attachment peg; and

wherein when said gripping member is assembled with said main body, said channels form a single contiguous channel sized and shaped to receive said O-ring and circumscribing said assembly.

14. The clamp as claimed in claim 13, wherein the height and width of said attachment side is generally equal to the height and width of said gripping member.

15. The clamp as claimed in claim 13, wherein the height and width of said at least one spacer is generally equal to the height and width of said gripping member.

16. The clamp as claimed in claim 13, wherein said number of bore holes is two.

17. The clamp as claimed in claim 13, wherein said at least one spacer comprises a plurality of spacers.

18. The damp as claimed in claim 13, further comprising said O-ring, wherein said O-ring comprises an elastic material and has an unexpanded circumference less than the circumference of said single contiguous channel.

19. The clamp as claimed in claim 18, wherein said O-ring is generally in the shape of a quadrilateral.

20. The clamp as claimed in claim 19, wherein said O-ring is generally in the shape of a square.
