  • Patent number: 8540464
    Abstract: Deburring knife for deburring straight or nonround hole edges with a base body driven rotationally around its longitudinal axis, in which one or more bar blades are replaceably accepted into a swivel-mounted knife holder in a base body, by which the knife holder has at least one control recess located on its circumference, in which a spring component engages, which guides the rotation of the knife holder in the base body, characterized by the fact that for pivot bearing of the knife holder in the base body of the knife holder there are two drilled holes located across from one another vertically to the mounting hole of the bar blade, into each of which the end of a bearing bolt engages, whose other end goes into a transverse hole in the base body and serves to rotate the knife holder in the base body that one or more bar blades are thereby easily and replaceably mounted in the radial mounting hole in the knife holder, that at least one stop preventing axial displacement and one pullout safety device for secur

  • Patent number: 7172373
    Abstract: The invention relates to a deburring tool with a quick change knife, which is formed by at least two parts, namely a guide sleeve having a larger diameter and a center bore, and a base body that can be inserted in the center bore in an axial direction. The base body can be secured in the center bore. A knife groove is arranged on the base body that can receive the knife to be secured, forming a pivot support in the base body. Due to this special support, the knife can be easily exchanged even when the deburring diameters are small, for example, less than 4 mm, while still being able to absorb large deburring forces.

  • Publication number: 20050129473
    Abstract: The invention describes a drill plate with a clamping attachment in a rotatably driven base body, which on one of its end faces forms a centering groove that is open towards the top. A clamping slot extending into the material of the base body is arranged at the bottom of the centering groove. The centering groove is bounded by at least two opposing mounting jaws, with at least two diametrically opposing stop faces arranged in the region of the clamping jaws for providing centering contact with the drill plate. The clamping attachment is formed by a mounting screw which clamps the drill plate in the centering groove (2.3). To improve transfer of the operating torque from the drill plate to the base body and to facilitate handling, at least two centering fins that are diametrically opposed with respect to the transverse center axis are arranged on the drill plate. The centering fins contact corresponding stop faces disposed on the corresponding clamping jaws of the base body.
