Method for deburring intersecting bore edges and tool for performing the method

摘要

Deburring tool with deburring blade (9) for deburring bore edges (3, 6) with straight or unrounded shape, consisting of a about its longitudinal axis (50) rotatably driven base body (12), at its lower end at least one blade holder (20) with at least one There mounted deburring blade (9) is mounted pivotably in the vertical direction on a base-side knife support (27), and on the outer periphery of the knife holder (20) in the radial direction outwardly open cam groove (31) is arranged, in which the free bendable end (30a ) of a bending spring (30) whose other end is clamped on the base body (12), wherein during deburring the deburring blade (9) from the base body (12) by an angle (51, 52, 53) to the longitudinal axis of the base body (12 ) is swung out and the knife axis (55) of the deburring blade (9) with its at least one cutting edge (39) on the deburred bore edge (3, 6) rests spring loaded and in the Rotation of the deburring tool of the contour of the bore edge (3, 6) performs spring-loaded pivoting movements, wherein the deburring blade (9) in the rest position pivoted out of the main body with its knife axis (55) deviates from the 90 degree position, angled pivot position (52, 53 ) and that the deburring blade (9) is associated with a backstop, which prevents pivoting back into the pivoted by 90 degrees from the base body (12) out position.
