Definitions

  • This invention relates, generally, to improvements in toolor cutter-heads of planers or shapers embodying a single double-faced cutting tool, and, more particularly, to a method of suspen- 6 sion of such heads, which, in combination with a plurality of auxiliary devices on both head and head-carrier, allows an automatic setting of the tool-head into its correct position for each operative run.
  • the objects of my invention are, first, to make use of but one cutting tool; second, to afford facili ties for the automatic setting of the tool-head into its correct position for each operative return run; and, third, to suspend the tool-head in its carrier in such a way, which, in combination with a set of stop-faces on both head and carrier, allows great chip-areas with a positive and steady operative action of the tool itself.
  • the holder in its carrier is allowed a pendulous motion releasing the swing of the holder for setting the clearance angle, the latter being the angular displacement of the tool, or its holder, about its longitudinal axis and is measured in a plane atright angles to said axis.
  • Fig. 1 is a side elevation of the tool-holder and appurtenant devices, partly in vertical section;
  • Fig. 2 a section along line 0-0 of Fig. 1;
  • Fig. 3 a side elevation of the cutting tool
  • Fig. 4 a front elevation of same
  • FIG. 5-9 side elevations of the cutting tool at various longitudinal and horizontal angular displacements, illustrating the pendulous motions of the tool-holder at the start, during, and at the end of its operative run;
  • Tool-holder a essentially of a cylindrical shape, carries a hand-Wheel g for swinging the holder about its longitudinal axis for for a purpose described subsequently.
  • the double suspension ne allows holder a to swing in a pendulous motion from the horizontal pivot 11. and a free displacement around its longitudinal axis on pivot 6.
  • Tool 1) possessing a double-faced cutting edge according to Figs. 3 and 4, is secured in its holder 0. by usual set-screws o.
  • Tool-holder a freely passes through an opening in frame I and is guided by two of the latters inner faces.
  • Two springs pushing up against a ring '0 carried around holder a, and bearing on frame I or respectively on part w of its support, are aiming to stop said pendulous motion of holder a and arrest the latter in the mean position according to Fig. 1.
  • the lower part of holder a possesses two check-faces p and p1, lying vertical in the normal position according to Figs. 1, 2 and 5 and in planes including equal horizontal angles with an axial plane II (Figs. 1 and 2).
  • In the opening of frame I I have another pair of 45 check-faces q and q1, lying in planes including equal vertical angles with said axial plane II and with their upper and lower marginal edges parallel to the latter.
  • Check-face a1 forms one side of a stop 0 which is horizontally adjustable 50 by means of a threaded spindle and a handwheel 71..
  • I On the upper side of frame I, on the four corners of the frame-opening and at the same height, I have four horizontally adjustable 5 stops k, each possessing two corners hi and k2 and between these latter a recess k3.
  • a principal advantage of the tool-holder at hand lies in the arrangement of the pendulumjoint en on its head in connection with the wide and substantial stop-faces p, q, 191 and (11 on its bottom-part, as hereby the bending stresses on the tool are kept small; the latter therefore does not start oscillating and thus allows be the planing of relatively great chip-areas.
  • the wide stopfaces easily take up the working pressure without giving rise to harmful turning moments in the tool and without subjecting the latter to torsional vibrations. a higher planing speed.
  • the stops k and i render complicated steering mechanisms, with their many attending troubles, unnecessary, allowing me by way of the pendulous motion of the toolholder to directly release the latters setting onto 10 the clearance-angle.
  • a toolor cutter-head for two-way planing a tool-holder in combination with a sliding head, said tool-holder having a pendulous l5 suspension around a horizontal axis of said sliding head at its top, a double-faced tool or cutter set in said tool-holder, said tool-holder being mounted rotatively around its longitudinal axis, stop-elements in said tool-holder and counterstops in'said sliding head, the latter lying in the path of the former when said tool-holder swings about said horizontal axis.
  • a tool-holder in combination with a sliding head, a tool-holder revolvably suspended from a horizontal axis of said sliding head at its top, a double-faced tool or cutter set in said tool-holder, said tool-holder aiso being revolva'oly mounted around its longitudinal axis, stop-elements on said tool-holder and co-unterstops on said sliding head, the latter lying in the path of the former when said tool holder swings about said horizontal axis, and vertical stop-faces on two opposite sides of said toolhoider lying askew to each other and counterstop-faces on said sliding head tapering, relative to each other, outward from top to bottom.
