Definitions

  • the invention relates to a rack of the type defined in the pre-characterising portion of Claim 1 for the housing, transport and presentation of machine tools.
  • the pre-characterising portion of Claim 1 is based on the disclosure of the document US-A-4155460.
  • a rack is proposed of the type referred to, consisting of an essentialy rectangular frame with a pair of longerons and a pair of transversals which define an internal cavity in which are interchangeably housed tool-holders for the tools.
  • Each holder presents a squared frame, two sides of which bear on and between the two longerons, while from lower on the bearing sides there extend fixing devices which project and engage onto various holes, chosen at will, among a number of holes in the surface of the longerons on which the tool holder bears.
  • each holder is obtained both from the shape of its own frame, which extends partially into the cavity between the longerons, following for some distance downwards the shape of the longeron internal walls, and from the use of locking elements consisting of L-sections applied to the longerons and bearing against the sides of the holders, guaranteeing that the holders remain in position during the movement of the tools.
  • the locking elements are either bolted to the longerons or locked on by a pin engaging in a "keyhole" shaped slot.
  • Bolts guarantee the complete immobility of the rack (and thus of the tool), but require too much time to release the L-sections during changing of the holder, while the engagement of a locking pin in a shaped slot, even where it is further blocked by a spring lock, allows a certain play of the holder, which is decidedly undesirable.
  • An object of the present invention is to solve the above mentioned problem and provide a holder-rack for machine tools as defined above, in which the holders are totally locked in position by L-sections which can be quickly and securely fixed to the rack and can be removed from it, without leaving any play.
  • the present invention concerns a rack for the housing, transport and presentation of machine tools, particularly for numerically controlled machines, capable of being mounted on a support with other or similar racks, said rack being of the type consisting of an elongated rectangular frame composed of two longitudinal longerons and a pair of separate parallel transversals, creating a space in which are interchangeably housed one or more tool holders, each having a rectangular frame adapted to be housed between said longerons and showing side portions which bear on the two longerons, said holders being positioned precisely and the exact positioning being repeatable by means of said holder portions which present projecting locating devices on the lower sides in contact with the longerons, which project and engage on several holes chosen at will from holes in the surface of the longerons on which the holders rest, these last being held fixed by means of locking pieces fitted to the longerons and consisting of L- rolled-sections, characterized in that said sections present at least one bayonet-type locking comprising bayonet fittings and key holes on the vertical walls of the L-sections and longer
  • a rack is formed by a frame consisting of a pair of longerons 2, 3 and two parallel transversals 4, 5 forming an essentially rectangular space 6.
  • tool-holders 8 In the cavity 6 thereof are housed tool-holders 8, each having a rectangular frame 7 forming two supports 9, 10 which are provided on their lower sides with locking devices, in this case pins, 12, which project and engage several holes, chosen at will from holes 11, to position the tool-holder on the surfaces 13, 14 of the longerons 3, 2 on which rest the supports 9, 10 of tool-holder 8.
  • the tool-holder 8 may, in the case illustrated in fig.1, present on one of the sides of the frame 7 a tooth or protuberance 8', integral with the tool-holder 8, for centering the flange of the tool, which carries a seat corresponding to the tooth 8', when that tool is being housed in said tool-holder 8.
  • this system allows the tool and tool-holder to be changed while retaining the same rack, thus reducing the size of the rack store; then, knowing with which holes the pins have to engage, it is possible to repeat the original position of the tools, i.e. the order in which they were arranged and their position on the rack before being substituted by other tools, with the complete and total precision required by the small tolerances allowed by mechanical arms.
  • the tool-holder 8 is locked in position by two L-sections 15, 16 each provided near its ends with bayonet fittings 18.
  • the holes 19 and fittings 18 correspond exactly in terms of size and location, to form a very precise lock upon insertion with a relative motion in a longitudinal direction. This movement exactly places the fittings 18 on the key-hole narrower portion.
  • a stop device is provided for, which is illustrated in more detail in figs. 3 and 4.
  • a metal tongue 20 On the internal part of the vertical part of the longerons 2, 3 is a metal tongue 20, one end of which is secured to the longeron itself, while the other end, which is "U" shaped, projects through a first hole 21 in the longerons to a second hole 22 in the corresponding section, thus preventing any lateral movement of the section in question.
  • the rack 1 may be fixed to any support, as for example, a trolley, by any known means; in a preferred embodiment the transversals 4 and 5 present at least two holes for bolting the rack 1 to a rack and thus obtaining a rigid structure.
  • each transversal presents six holes 23 to locate the rack as preferred; using two at a time, the rack 1 may be anchored securely, preventing movements on the level or when inclined, there being more inclined positions available depending on the holes used, each position being fixed and repeatable.
  • the invention provides a rack for machine tools in which the bayonet fitting on the L-sections and the snap-stop allow easy locking of the tool-holders, and equally quick and easy unlocking, while locking the tool-holders with great precision and, above all, with that demanded by the requirements of numerically controlled machines.
