Abstract
A planing tool has a cylindrical body with elongated axially extending grooves in which elongated inserts with planing members are received, adjusting screws extending in a radial direction and arranged to adjust the radial distance of the inserts from the axis of rotation of the body, clamping screws arranged to clamp the inserts in the elongated grooves, wherein each adjusting screws extends through an opening of the respective insert with play, and a spring element is located between a bottom wall of each of the grooves and a respective one of the inserts.
Claims12
A planing tool, particularly for a manually operable planing machine, comprising a body having an axis of rotation, a peripheral surface and a plurality of elongated grooves on said peripheral surface, said grooves extending substantially in an axial direction and being spaced from one another in a circumferential direction, each of said grooves being limited by a bottom wall;
- a plurality of elongated inserts each carrying an elongated planing knife and inserted in a respective one of said grooves;
- adjusting means arranged to adjust the radial distance between said inserts and said axis of rotation of said body, said adjusting means including a plurality of adjusting screws each extending in a substantially radial direction and having a projection;
- clamping means arranged to clamp said inserts in said grooves of said body, said clamping means including a plurality of clamping screws each movable between a clamping position in which it clamps one of said inserts in a respective one of said grooves, and unclamping position in which it releases the same so that said insert can be withdrawn from said one groove;
- means for receiving each of said adjusting screws, said receiving means including a through-going opening formed in each of said inserts so that each of said adjusting screws can extend through a respective one of said opening with play, and a threaded hole formed in said body so that each of said adjusting screws can be threaded into a respective one of said threaded holes;
- and means for pressing each of said inserts against said projection of a respective one of said adjusting screws, said pressing means including at least one spring element extending between the bottom wall of each of said grooves and a respective one of said inserts.
