Abstract
Embodiments of the invention are directed towards apparatus for securing workpieces in a workpiece retention device or clamp. In one embodiment, a workpiece retention tool is described, where the work piece retention tool comprises a clamp assembly and at least two gripping attachments configured to retain the workpiece. The gripping attachments are configured to exert a compressive force of the workpiece. In a particular implementation, the two gripping attachments include base and retention head portions. Here, the retention head portion is further defined with a top portion and a bottom portion defining an inclined gripping surface.
Claims20
A workpiece retention tool, comprising:
- (a) a clamp assembly;
- (b) at least two gripping attachments selectively coupleable to the clamp assembly and configured to retain the workpiece, wherein the at least two of the gripping attachment are configured to exert a compressive force of the workpiece;
- (c) the at least the two gripping attachments includes base and a retention head, the retention head having a top portion and a bottom portion defining an inclined gripping surface, wherein the top portion of the retention head extends beyond the bottom portion of the retention head.
A workpiece retention tool, comprising:
- (d) an expansion collar having a cylindrical shape adapted to secure substantially cylindrical workpiece, the expansion collar having a plurality of slots extending from a first end face, and a plurality of slots extending from a second face, wherein the plurality of slots extending at least half the width of the expansion collar;
- (e) at least two expansion promoters configured to engage the first face and second face and cause the first and second faces to increase in diameter in response to a compressive force;
- (f) a mounting element configured to mount the workpiece retention tool on or to a surface;
- and
- (g) a selectively engagable compression device configured to apply compressive force to at least the two expansion promotors so as to apply compressive force to the first and second faces of the expansion collar.
A workpiece retention apparatus, comprising:
- (h) a base portion comprising
- a. An elongated shaft member, a hinge member disposed at one end of the elongated shaft member, the hinge member having at least one through bore disposed therein, and
- (i) A workpiece mount comprising
- a. a connection portion configured to removably couple to the hinge member, an angled mounting shaft connected at one end to the connection portion, and a vertical mounting shaft connected to the other end of the angled mounting shaft.
