Abstract
A holder blade is provided which includes an elongated member including an insert cavity for securing an insert in place. The insert cavity includes opposing surfaces which include V-shaped lengths which engage corresponding V-shaped lengths provided in opposite surfaces of the insert. A camming action is provided so that the opposing surfaces of the insert cavity may tightly grip the insert.
Claims18
A holder blade comprising a member extending along a longitudinal axis and having a first end and an opposite second end and an upper surface and a lower surface, at least one of said first end and said opposite second end comprising an insert cavity segment, said insert cavity segment comprising:
- an insert cavity extending into an end of said member, said insert cavity having a first surface and an opposite second surface, said first surface and said opposite second surface each comprising a V-shaped segment which extends in an insert receiving direction of said insert cavity and is configured to mate with corresponding V-shaped segments of opposing surfaces of an insert;
- an aperture extending through said member in the direction of a transverse axis, said aperture comprising a cam follower surface, said upper surface having an opening which communicates with said aperture;
- a first elongated slot extending through said member in the direction of said transverse axis and being oriented towards said insert cavity at a first angle relative to said longitudinal axis, said first angle aligning the length of said first elongated slot in the direction of the length of the insert cavity, said first elongated slot being positioned at a location between said insert cavity and said aperture and communicating with said aperture via a second elongated slot extending through said member in the direction of said transverse axis and being oriented away from said insert cavity at a second angle relative to said longitudinal axis, said second angle being different from said first angle and said second elongated slot extending from said first slot to said aperture, said aperture communicating with said opening in said upper surface via a third elongated slot extending through said member in the direction of said transverse axis and oriented away from said cavity in the direction of said second angle, said first elongated slot, said aperture, said second elongated slot and said third elongated slot forming a resilient segment of said member, said resilient segment extending from said first surface to said opening in said upper surface;
- and
- a cam positioned in said aperture for rotational movement relative to said cam follower surface and having a cam surface which is engagable and disengagable with said cam follower surface when said cam is rotated, whereby engagement of said cam surface with said cam follower surface causes said resilient segment to bend and move said first surface towards said opposite second surface, and disengagement of said cam surface from said cam follower surface causes said resilient segment to spring back to its initial position and move said first surface away from said opposite second surface.

A holder blade comprising a member extending along a longitudinal axis and having a first end and an opposite second end and an upper surface and a lower surface, at least one of said first end and said opposite second end comprising an insert cavity segment, said insert cavity segment comprising:
- an insert cavity extending into an end segment of said member at said first end, said insert cavity having a first surface and an opposite second surface, said first surface and said opposite second surface each comprising a V-shaped length which extends in an insert receiving direction of said insert cavity and is configured to mate with corresponding V-shaped lengths of opposing surfaces of an insert, the width of said end segment of said member being less than the width of an adjacent segment of said member, said member comprising a concave curved surface adjacent said end segment, facing said insert cavity and extending from said upper surface at a first position to said lower surface at a second position, said second position being closer to said first end than is said first position;
- an aperture extending through said member in the direction of a transverse axis, said aperture comprising a cam follower surface which is oriented away from said insert cavity at a first angle relative to said longitudinal axis, said upper surface having an opening which communicates with said aperture by means of a first elongated slot which extends through said member in the direction of said transverse axis and is oriented away from said insert cavity at said first angle, said first elongated slot extending from said aperture to said upper surface;
- a second elongated slot extending through said member in the direction of said transverse axis and being oriented towards said insert cavity at a second angle relative to said longitudinal axis so as to align the length of the second elongated slot in the direction of length of the insert cavity, said second elongated slot having a first radiused end segment and an opposite second radiused end segment, said second elongated slot being positioned at a location between said insert cavity and said aperture, said second elongated slot communicating with said aperture by means of a third elongated slot extending through said member in the direction of said transverse axis and being oriented away from said insert cavity at said first angle, said third elongated slot extending from said second elongated slot to said aperture, said first elongated slot, second elongated slot, third elongated slot and aperture extending through said member to form a resilient segment of said member which extends from said first surface to said opening in said upper surface;
- and
- a cam positioned in said aperture for rotational movement relative to said cam follower surface and having a cam surface which is engagable and disengagable with said cam follower surface when said cam is rotated, whereby engagement of said cam surface with said cam follower surface causes said resilient segment to bend and move said first surface towards said opposite second surface, and disengagement of said cam surface from said cam follower surface causes said resilient segment to spring back to its initial position and move said first surface away from said opposite second surface.
