Tool holder with upper and lower jaws defining an insert receiving pocket and cutting tool

A tool holder (20), comprising:

• a holder body (22) extending in a rearward-to-forward direction (DR, DF) along a longitudinal axis (AL), the holder body (22) having:
• top and bottom body surfaces (50, 53), and first and second body side surfaces (36a, 36b) extending between the top and bottom body surfaces (50, 53);
• an insert receiving pocket (34) located at a forward end (37) of the holder body (22), the insert receiving pocket (34) defined by opposing upper and lower jaws (26, 28), the upper jaw having a top jaw surface (40), one of the upper and lower jaws (26, 28) being resiliently displaceable with respect to the other;
• a resilience slot (38) communicating with and extending away from the insert receiving pocket (34) in the rearward direction (DR) and further separating the upper and lower jaws (26, 28):
• upper and lower pocket surfaces (30, 32) defined on the upper and lower jaws (26, 28), respectively;
• a first plane (P1) containing the longitudinal axis (AL), passing in-between the first and second body side surfaces (36a, 36b) and intersecting the top and bottom body surfaces (50, 53) and also the upper and lower pocket surfaces (30, 32);
• a first axis (A1) contained in the first plane (P1) and perpendicular to the longitudinal axis (AL), the first axis (A1) extending in an upward-to-downward direction (DU, DD) transverse to the longitudinal axis (AL) and intersecting the top jaw surface (40);
• an actuator (42) extending from the upper jaw (26) along the first axis (A1) in the downward direction (DD) and traversing the resilience slot (38), the upper jaw (26) and the actuator (42) being integrally formed having unitary one-piece construction, the actuator (42) having an activation aperture (76);
• and
• an access bore (46) formed in the lower jaw (28) and extending along a second axis (A2) which intersects the first plane (P1);
• and
• a lock (48) extending along a third axis (A3) which intersects the first plane (P1), the lock (48) occupying the access bore (46) and engaging the actuator (42);
• wherein:
• in a plane perpendicular to the first axis (A1) and also perpendicular to the first plane (P1), the actuator (42) has an oblong shape, with a lateral width (WLT) perpendicular the first plane (P1) and a longitudinal width (WLG) parallel to the longitudinal axis (AL), the lateral width (WLT) being less than half the longitudinal width (WLG).

A tool holder (20), comprising:

• a holder body (22) extending in a rearward-to-forward direction (DR, DF) along a longitudinal axis (AL), the holder body (22) having opposing upper and lower jaws (26, 28) respectively defining upper and lower pocket surfaces (30, 32) of an insert receiving pocket (34), one of the upper and lower jaws (26, 28) being resiliently displaceable with respect to the other,
• a resilience slot (38) communicating with and extending away from the insert receiving pocket (34) and further separating the upper and lower jaws (26, 28), the resilience slot (38) having opposing upper and lower slot surfaces (39, 41) disposed on the upper and lower jaws (26, 28), respectively, the upper slot surface (39) facing in a downward direction (DD) and the lower slot surface (41) facing in an upward direction (DU) opposite to the downward direction (DD), and
• a first plane (P1) containing the longitudinal axis (AL), and intersecting the upper and lower pocket surfaces (30, 32),
• wherein:
• an actuator (42) extends from the upper jaw (26) along a first axis (A1) in the downward direction (DD) and traverses the resilience slot (38), the actuator (42) comprising an activation aperture (76),
• an access bore (46) formed in the lower jaw (28) extends along a second axis (A2), and
• a lock (48) extending along and rotatable about a third axis (A3) non-threadingly occupies the access bore (46) and engages the activation aperture (76),
• and wherein:
• the upper jaw (26) has a top jaw surface (40) facing in the upward direction (DU),
• the first axis (A1) intersects the top jaw surface (40);
• the upper and lower pocket surfaces (30, 32) are spaced apart by a clamping distance (DC),
• the clamping distance (DC) is increased or decreased by rotation of the lock (48) about its third axis (A3), and
• during rotation of the lock (48) about its third axis (A3), the actuator (42) is entirely spaced apart from the lower jaw (28) and makes no contact therewith.
