Definitions

  • said tool-holder includes a shoe adapted to be positioned at any desired point of the transverse slideway either to the front or to the rear of the part to be machined, which shoe may carry one or more tools fitted in any desired position between said shoe and a carrier plate which is secured to the shoe by means of vertical threaded ties extending through openings selected as required out of a series of openings formed in said plate and screwed for instance into nuts adjustably positioned at selected points of transverse grooves formed in the shoe.
  • Removable tubular stays surround a number of said ties so as to hold the shoe spaced with reference to the carrier plate while the actual tools are held by screws and shims at the desired locations.
  • FIGS. 1 and 2 are elevational views of a tool-holder fitted on the slideway respectively in partly sectional, partly elevational view and in end view;
  • FIG. 3 is a view thereof as seen from above;
  • FIG. 4 illustrates a modification seen endwise as in the case of FIG. 2.
  • the shoe 1 is secured by a clamp 4 at any desired point to the upper longitudinal dove-tailed surface of the transverse slideway.
  • Said shoe is adapted to receive at any point of its surface a tool 12 or 13 and may be positioned to either side of the part 5 to be machined.
  • a tool 12 or 13 may be positioned to either side of the part 5 to be machined.
  • I have illustrated at 1 in dot-and-dash lines a second position which may be occupied by the shoe together with the other part of the toolholder, said second position lying to the right-hand side of the part 5 whereas the position illustrated in solid lines and described herei-nabove lies to the left-hand side thereof.
  • the plate 8 of the toolholder over the tools 12 and 13 to be secured between said plate and the shoe in any desired position.
  • the plate 8 is secured to the shoe 1 by means of vertical threaded ties 11 extending through the plate and screwed into the shoe 1 for instance through engagement with the nuts 7 adapted to slide in the transverse T-shaped grooves 6 and 6' formed in the shoe in parallelism with the axis of the part 5 to be machined. Said nuts are held in position at selected points of the grooves under the action of the tractional effect obtained by the screwing of the corresponding ties.
  • Said ties are reinforced by removable tubular stays 9 of a suitable length which hold the plate 8 and shoe 1 apart with the desired predetermined spacing.
  • FIG. 3 is a plan view showing the relative location of the openings formed in the plate 8 and through which the ties 11, 16 are to be fitted. These openings are distributed along transverse lines the spacing of which must b ⁇ : equal to that of the grooves 6 and 6 formed in the s cc.
  • FIG. 4 I have illustrated a modification wherein the ties which are associated with stays are arranged in the vicinity of the opposite transverse edges of the plate 8 and of the shoe 1.
  • a tool-holder for lathes and the like machine-tools provided with a transverse slideway
  • said tool-holder comprising a shoe adapted to be secured at any desired point of the length of the transverse slideway extending to the front and to the rear of the part to be machined, said shoe being provided with a plurality of transverse T- shaped grooves perpendicular to the slideway, a plate extending above the shoe and provided with openings distributed along parallel lines registering vertically with said grooves, a plurality of vertical headed stays extending through selected openings of said plate and the lower ends of which are threaded, nuts engaging slidingly the transverse grooves of the shoe and screwed over the lower ends of the stays, at least one tool system fitted between the plate and the shoe, shims inserted between the upper ends of the tool systems and the plate to clamp said tool systems in the desired position against the shoe and the shims and plate against the heads of the stays and screws holding the shims in position and extending through the plate.
  • a tool-holder for lathes and the like machine-tools provided with a transverse slideway
  • said tool-holder comprising a shoe adapted to be secured at any desired point of the length of the transverse slideway extending to the front and to the rear of the part to be machined, said shoe being provided with a plurality of transverse T- shaped grooves perpendicular to the slideway, a plate extending above the shoe and provided with openings distributed along parallel lines registering vertically with said grooves, a plurality of vertical headed stays extending through selected openings of said plate and the lower ends of which are threaded, nuts engaging slidingly the- No references cited.
