Abstract
A rotating shaft tool has a base body, with a guide slot in the base body, in which at least one elongate cutting blade can be arranged. An axial adjustment means which can be arranged at the mouth of the guide slot and by means of which the cutting blade can be adjusted axially in the guide slot. At least one spherical force exerting element, capable of moving the cutting blade in the axial direction, can be arranged at one end face of the cutting blade. Its axial displacement can be adjusted by means of at least one second force exerting element which deviates from the direction of movement of the first spherical force exerting element.
Claims22
A rotating shaft tool, comprising:
- a body (12) having a guide slot (17) in which at least one elongated cutting blade (18) can be arranged,
- an axial adjustment device (26, 27) arranged at the mouth of said guide slot (17) by means of which said cutting blade (18) can be adjusted axially in said guide slot (17),
- wherein said axial adjustment device (26, 27) comprises:
- at least a first force exerting element (32) with at least one rounded contact surface (35) positioned towards an end face (33) of said cutting blade (18) for moving said cutting blade (18) in an axial direction, and
- at least one second force exerting element (36) for adjusting said first force exerting element (32), which second force exerting element (36) deviates from the direction of movement of said first force exerting element (32),
- in which said first force exerting element (32) is guided axially with respect to said guide slot (17).
A rotating shaft tool, comprising:
- a body (12) having a guide slot (17) in which at least one elongated cutting blade (18) can be arranged,
- an axial adjustment device (26, 27) arranged at the mouth of said guide slot (17) by means of which said cutting blade (18) can be adjusted axially in said guide slot (17),
- wherein said axial adjustment device (26, 27) comprises:
- at least a first force exerting element (32) with at least one rounded contact surface (35) positioned towards an end face (33) of said cutting blade (18) for moving said cutting blade (18) in an axial direction, and
- at least one second force exerting element (36) for adjusting said first force exerting element (32), which second force exerting element (36) deviates from the direction of movement of said first force exerting element (32),
- wherein said end face (33) of said cutting blade (18) extends at an angle of less than ninety degrees to said guide slot (17).
A rotating shaft tool, comprising:
- a body (12) having a guide slot (17) in which at least one elongated cutting blade (18) can be arranged,
- an axial adjustment device (26, 27) arranged at the mouth of said guide slot (17) by means of which said cutting blade (18) can be adjusted axially in said guide slot (17),
- wherein said axial adjustment device (26, 27) comprises:
- at least a first force exerting element (32) with at least one rounded contact surface (35) positioned towards an end face (33) of said cutting blade (18) for moving said cutting blade (18) in an axial direction, and
- at least one second force exerting element (36) for adjusting said first force exerting element (32), which second force exerting element (36) deviates from the direction of movement of said first force exerting element (32),
- wherein said first force exerting element (32) is arranged in a first guide (31) that is at least slightly inclined inward with respect to the axis of rotation (11) of said rotating shaft tool.
