Definitions

  • Said tool-carrying part revolves inside a cylindrical chamber in which an armate bearing is provided for said part, the substantially radial terminal surfaces of which form abutment surfaces for a radial blade carried by the revolvable part and urged selectively by a hydraulic fluid towards said surfaces defining the corresponding extreme positions of the revolvable part.
  • My invention has for its object a turret carrying two tools adapted to be selectively brought into engagement with the work to be cut on a lathe, said tools lbeing constituted by roughing out, finishing, truing or the like tools.
  • said tools are carried by the turret with the interposition of a rotary part adapted to be angularly shifted between two positions corresponding to the operative positions of said tools respectively, said turret being held in the position occupied by it by the pressure of a fluid acting on said part.
  • said part carries inside a closed annular chamber a radial blade adapted to engage for each of said positions of the rotary part which are at 180 apart, corresponding stationary abutment surfaces in registry with each of which it is possible to subject the radial blade to a hydraulic pressure urging the latter towards the other abutment surface.
  • FIG. 1 is an elevational view of the turret seen at an angle of about 35.
  • FIG. 2 is a vertical cross-section through line II-II of FIG. 3.
  • FIG. 3 is a horizontal axial cross-section of the turret through line III III of FIG. 1.
  • the turret includes a shoe or block 1 the lower surface of which is provided with a dove-tail along which the turret is fitted as a whole on the slideway of a copying lathe, for instance through the agency of the corner clamp 2" and lateral clamps 2.
  • Said shoe or block is also provided with a horizontal bore 3 the ends of which are closed by flanges 4 and 5 which are themselves provided with bores of a diameter less than that of the bore 3 in the block 3.
  • Inside said bores provided in the flanges coaxially with the bore 3 is revolvably fitted the part 6 the outer broader head of which extends over the flange 4 which carries removably the tool holder 19.
  • the tool holder illustrated carries two tools 17 and 18 in diametrically opposed relationship.
  • Suitably positioned screws secure the flanges 4 and 5 on the block 1.
  • a washer or disc 7 is secured over the flange 5 by the screws 7 and forms a bearing surface for the end of the part 6 opposed to the tool holder.
  • Two hydraulic pipes 14 and 15 open at two substantially diametrically opposed points of the chamber A so as to exert alternatingly a thrust on the blade 12 screwed radially to the other periphery of the part 6 extending throughout the axial length of the chamber A and engaging fluidtightly the wall of the bore 3 inside the block 1.
  • the angular shifting in either direction applied to the blade 12 and consequently to the part 6 is limited to by abutment surfaces 13, 13 constituted by the ends of a semi-annular insert 9 fitted inside the corresponding section of the annular chamber A and held therein by a key 11 engaging the inner periphery of the block 1 to which it is secured by the screws 20 illustrated in FIG. 2.
  • the abutment surfaces 13 and 13 at the transverse ends of the insert 9 are illustrated in FIG. 2 as at substantially 180 with reference to each other. They are in fact coplanar in a plane parallel with a diametrical plane of the chamber A and extending slightly beyond a plane tangent to the hydraulic pipes 14 and 15 on the side facing the axis XX of the turret block and nearer XX.
  • the transverse ends of the insert 9 are cut off adjacent their outer edges at 14 and 15 that is along the portion of the surface of the insert facing the wall of the bore 3 in registry with the outlets of the hydraulic pipes 14- and 15. The latter open thus freely into the chamber A along the cut off edges 14 and 15 as soon as the closing blade 12 has disengaged the corresponding abutment 13 or 13.
  • a distributor controlled manually, electn'cally or otherwise is adapted to reverse the direction of the hydraulic circuit feeding the pipes 14 and 15. Assuming the blade 12 is in the position illustrated in FIG. 2, which implies that one of the tools carried in a predetermined angular position by the part 6 with the interposition of the tool holder 19 is in its operative position, it is suflicient to make the hydraulic pressure act at 15-15 so as to urge the blade away from the abutment surface 13 and to shift it in the direction of the arrow 16 until it engages the other abutment surface 13 through its side facing away from the first-mentioned abutment surface.
  • the thickness of the blade 12 is equal to twice the distance separating the plane defined by the abutment surfaces 13-13 from the axis XX of the block 1 whereby the blade is constrained, as illustrated, to execute an angular shifting through accurately 180 at each operation.
  • the blade 12 When the blade 12 has executed an angular movement through 180, it is stopped by the opposite abutment surface 13', whereby the second tool is brought into its operative position and replaces the tool precedingly in said position.
  • the blade delivers the hydraulic liquid back towards the distributor along the cut off edge 13 and through the pipe 14.
  • the first tool can be brought again into its operative position now occupied by the second tool and to this end the fluid pressure is reversed so as to make the hydraulic fluid enter the annular chamber A through the pipe 14 so as to make the blade disengage the abutment surface 13 and to return it into the position illustrated in FIG. 2.
  • a carrier block provided with a cylindrical chamber open at both ends
  • a part annular cylindrical insert rigidly secured coaxially in said chamber along a portion of the inner periphery thereof extending between the longitudinal edges of said insert
  • annular flanges secured over the transverse ends of the chamber and of the insert therein
  • a cylindrical member revolvably and coaxially carried by said part annular insert leaving a part annular'gap between it and the inner surface of the chamber along its peripheral area extending between the longitudinal edges of the insert
  • a tool holder rigidwith said cylindrical member and engaging the outer surface of one of said flanges, two tools carried by the tool holder and facing away from said one flange
  • a plate removably secured to the end of the cylindrical member opposed to the tool holder and engaging the outer surface'of the other flange to prevent the cylindrical member and tool holder from moving longitudinally
  • an abutment rigid with the cylindrical member along a generating line thereof dividing the part annular
