Abstract
A tenoner provided with two driven milling cutters positioned opposite each other on both sides of a traveling carrier for a workpiece. Each cutter is carried in a carriage mounted in a supporting element which comprises a base displaceable on the frame in two mutually perpendicular directions. The carriage is tiltable around two mutually perpendicular axes for setting the location and angular position of a tenon. These axes intersect each other at an imaginary point coinciding with the root of the tenon, which is i.e. the center of the common attachment plane of tenon and workpiece. The cutters each make a stepwise revolution and a rectilinear reciprocating motion around the root in producing a tenon. Because of this arrangement, the angular setting of the cutter can be quickly adjusted.
Claims20
A tenoner comprising a frame;
- at least one displaceable workpiece carrier in the frame;
- two supporting elements mounted in the frame at opposite ends of the workpiece carrier;
- a carriage mounted in each supporting element, each carriage being displaceable in two mutually perpendicular directions and tiltable around two mutually perpendicular axes for setting the relative location and angular position of a tenon;
- an adjustable milling cutter journaled upon each carriage;
- and means for periodically imparting to each cutter a stepwise revolving movement of 180.degree. around an axis, the axis extending in a direction for causing the cutter to cut a rounded side of the tenon being milled.
An apparatus for milling tenons in a workpiece, comprising:
- (A) a frame;
- (B) a workpiece carrier for carrying a workpiece along a path through the frame;
- (C) a first cutter assembly mounted to the frame and disposed at a first side of the path for milling a first tenon in the workpiece;
- and
- (D) a second cutter assembly mounted to the frame and disposed at a second side of the path opposite the first side for milling a second tenon in the workpiece;
- each of the first and second cutter assemblies comprising:
- (1) a support assembly mounted on the frame, comprising a carriage tiltable in first and second directions around respective first and second axes and displaceable relative to the frame in two mutually perpendicular directions;
- and
- (2) a cutter mechanism for milling the tenon in the workpiece, the cutter mechanism being mounted on the carriage and being displaceable and tiltable therewith for setting the location and position of the tenon to be milled.
A tenoner comprising:
- a frame;
- a displaceable workpiece carrier in the frame;
- two supports mounted to the frame at opposite ends of the workpiece carrier;
- each support comprising a supporting element and a carriage mounted on the supporting element and displaceable in two mutually perpendicular directions and tiltable around two mutually perpendicular axes for setting the relative location and angular position of a tenon being milled;
- and
- two adjustable milling cutters, each including a drive and each journaled upon a respective one of the carriages for periodic stepwise revolving movement of 180.degree. around a respective axis, each axis extending in a direction for causing the respective cutter to cut a rounded side of the tenon being milled.
