Description

Angle floating deburring knife handle

Technical Field

The utility model discloses a floating knife handle, belongs to the technical field of floating knife handles, and particularly relates to an angle floating deburring knife handle.

Background

The floating deburring tool holder is a floating tool for removing burrs of uneven contours (edges) generated in the machining process, and can automatically compensate between the actual contours of a workpiece and a program. The floating mechanism of the cutter handle can move and machine along the uneven edge of the workpiece, so that the cutter can have 5-10mm edge compensation. The pressure at the edge of the workpiece can be regulated by a regulating mechanism in the tool handle, and the tool can be directly driven by a main shaft of the machine tool.

However, the floating tool handle in the prior art can only float front and back during working, and cannot realize multi-angle floating work, so that accumulated errors are increased, and meanwhile, the common floating tool handle cannot compensate the appearance errors of the workpiece, so that burrs cannot be removed when the machining edge of the workpiece is tightly attached.
