Definitions

  • a clamping holder comprising an elongated groove of dovetailed cross-section for lengthwise accommodation of the square steel bar of a cutting tool to be clamped therein, and comprising a wedge-like liner of U-shaped cross-section placed with transversal play in the groove and adapted to embrace the tool bar on three longitudinal sides, the liner having on its flanks outer wedge surfaces on opposite sides longitudinally to the groove and a middle wall connecting the flanks and being located near the longitudinal opening of the groove, the middle wall being traversed by pressing screws screwed therein for engaging the middle side of the embraced sides of the tool bar and urging the latter with its opposite longitudinal side into clamping engagement with the base surface of the groove, whereby the flanks of the liner are adapted to press upon the two other longitudinal sides of the tool bar.
  • one of the flanks of the liner has formed a recess therein, and a securing pin is screwed into the holder portion adjacent to this flank and projects into the recess for securing the liner against lengthwise displacement in the groove of the holder.
  • FIG. 1 is a lateral elevation of the clamping holder
  • FIG. 2 is a vertical section along line II-II in FIG. 1; and;
  • FIG. 3 is a vertical section along line Ill-III in FIG. 1.
  • the tool holder 1 shown in FIGS. 1 to 3 comprises an elongated groove 2 of dovetailed cross-section wherein a clamping liner 3 is placed with transversal play. It is best seen in FIG. 3 that this liner 3 has a U-shaped cross-section with two wedge-like flanks 4 the outer surface 5 of which is parallel to the one respectively the other of the longitudinal lateral surfaces 6 of the dovetailed groove 2.
  • the square steel bar 7 of a cutting tool 8, such as a lathe tool is embraced on three longitudinal sides by the liner 3, whereby the inner surface 9 of its two flanks 4 substantially abut each against one of two opposite longitudinal sides of the tool bar 7.
  • the middle wall 10 of the liner 3, which connects the flanks 4 is located near the longitudinal opening of the groove 2 and is traversed by two headless pressing screws 11 screwed therein and having a hexagonal hole 12 in the outer front end.
  • a securing pin 14 is screwed through a holder portion being adjacent to one of the flanks 4 of the liner and projects with its inner end 15 into a recess provided in this flank.
  • a clamping holder for a cutting tool comprising a holder body provided with an elongated groove of dovetailed cross-section for lengthwise accommodation of the square steel bar of the cutting tool to be clamped therein, a wedge-like liner of U-shaped crosssection placed with transversal play in said groove and adapted to embrace the tool bar on three longitudinal sides, said liner having two flanks withan outer wedge surface on opposite sides longitudinally to said groove and a middle wall connecting said flanks and being located near the longitudinal opening of said groove, one of said flanks of said liner formed with a recess therein, a securing pin screwed into said holder body adjacent to said flank and projecting into said recess for securing said liner against lengthwise displacement in said groove of said holder body and pressing screws screwed through said middle wall for engaging the middle of the embraced sides of the tool bar and for urging the latter with its opposite side into clamping engagement with the base surface of said groove, whereby said flanks of said liner are under wedge action by said
