Abstract
The invention relates to a cutting tool with a supporting body and at least one receptacle (2), which is arranged in the supporting body (1), is openly formed to allow a cutting edge (3) of a cutting element (4) to pass through and in which the cutting element (4) is clamped in its seat by means of at least one clamping jaw (5). The object of the invention is to improve the cutting tool with respect to the cutting behavior and cost-effectiveness. This object is achieved by the cutting jaw (5) being formed resiliently in the direction of the cutting element (4).
Claims15
A cutting tool comprising:
- a supporting body and at least one receptacle which is arranged in the supporting body;
- at least one cutting element having a cutting edge, the at least one receptacle being designed to be open to allow the cutting edge of the at least one cutting element to pass through;
- and
- at least one clamping jaw having a width and height which clamps the at least one cutting element in its seat, wherein the at least one clamping jaw is configured to be elastic in the direction of the at least one cutting element and has one or more grooves extending the entire width of the at least one clamping jaw on a side of the clamping jaw opposite the at least one cutting element,
- wherein the clamping jaw is coupled to the supporting body via a screwed connection and clamps the cutting element such that the width of the at least one clamping jaw is parallel to an axial direction of the supporting body.
2 more elements
A cutting tool comprising:
- a supporting body having a receptacle incorporated therein;
- a cutting element inserted into the receptacle, the receptacle serving as a seat for a cutting element;
- a clamping jaw having a width and height which clamps the cutting element arranged opposite the seat;
- and
- a screw, clamping of the cutting element being effected by means of the screw which, through a through-hole in the supporting body, engages in a thread incorporated in the clamping jaw and clamps the cutting element in place after application of a fixed torque,
- wherein incorporated on a side of the clamping jaw opposite the cutting element are one or more grooves extending the entire width of the clamping jaw which result in a weakened location on account of an absence of material, and the weakened location results in a hinge effect about the one or more grooves,
- wherein the clamping jaw has a projection which engages in a corresponding groove in the cutting element and which, in addition to a clamping force applied by the screw, forms positive locking against a radial displacement of the cutting element on account of centrifugal forces that occur, and
- wherein the width of the clamping jaw is parallel to an axial direction of the supporting body.
5 more elements
A cutting tool comprising:
- a supporting body having a receptacle incorporated therein;
- a cutting element inserted into the receptacle, the receptacle serving as a seat for a cutting element;
- a clamping jaw having a width and height which clamps the cutting element arranged opposite the seat;
- and
- a screw, clamping of the cutting element being effected by means of the screw which, through a through-hole in the supporting body, engages in a thread incorporated in the clamping jaw and clamps the cutting element in place after application of a fixed torque,
- wherein incorporated on a side of the clamping jaw opposite the cutting element are one or more grooves extending the entire width of the clamping jaw which result in a weakened location on account of an absence of material, and the weakened location results in a hinge effect about the one or more grooves,
- wherein the clamping jaw has a projection which engages in a corresponding groove in the cutting element and which, in addition to a clamping force applied by the screw, forms positive locking against a radial displacement of the cutting element on account of centrifugal forces that occur,
- wherein an axial locking stud is passed through a hole into the seat of the cutting element in the receptacle, the hole for the axial locking stud being located radially inward of the through-hole for the screw, the screw engaging in a thread of the clamping jaw and having a head which locks the axial locking stud, the clamping jaw forming an opposite bearing surface for the axial locking stud, such that the latter is secured in a fitted state,
- wherein the cutting element includes a recess, the recess corresponding to the axial locking stud and enclosing the axial locking stud in the fitted state so that a displacement of the cutting element in an axial direction of the supporting body is prevented, and
- wherein the width of the clamping jaw is parallel to an axial direction of the supporting body.
