  • FIG. 13 FIXING A DEVICE OR PUTTING ICE Sept. 13, 1966 PROCESS AND APPARATUS FOR DETACHABLY ON A MACHINE AND INSTALLATION F THIS PROCESS INTO PRACT 5 Sheets-Sheet 4 Filed Aug. 15, 1963 FIG. 13
  • the present invention concerns a process for detachably fixing a device for example, a work-piece to be machined or a tool on a machine in a specified position.
  • An object of the present invention is to avoid in many cases of the adjustment of a tool or other device on the machine itself with respect to another device fixed on the machine, and to replace the direct adjustment by a preliminary indirect adjustment outside and independent of the machine.
  • a process for detachably fixing a device on a machine is characterized in that there is connected with the machine, in a specified position, one of two complementary brackets, adapted to be connected together in at least one mutual, perfectly specified position, and in that there is specified in advance the said prescribed position of the device with respect to the machine, once the brackets are assembled, in placing it on the other bracket in a perfectly specified position.
  • brackets Because one of the brackets is connected with the machine in a known specified position, it is possible to specify exactly in advance the relative position of the device with respect to any part of the machine in specifying the position of the device with respect to the other bracket, because the relative position of the two assembled brackets is equally predetermined and known.
  • a machine tool it is preferable to fix notonly one or several tools and one or several work-pieces to be machined by these tools by means of a pair of brackets as described above, so that the relative positions of the tools and of the work-pieces to be machined can be predetermined in advance outside the machine.
  • the installation for putting into practice the process described above is characterised by two types of complementary brackets, adapted to be connected together in pairs in at least one mutual perfectly specified position, one of the said types of brackets comprising means permitting the fixing of a device on this bracket in a perfectly specified position and the other of the said types of brackets comprising means permitting its fixing on the machine in a specified position, several brackets belonging to the same type of bracket, so that at least one bracket connected with a device can successively be connected with several complementary brackets or that several brackets carrying devices can be connected successively with at least one complementary bracket.
  • FIG. 1 is a perspective exploded view of a known machine for machining by electro-erosion
  • FIGS. 2 to 5 are perspective details of the machine, in accordance with the invention, for executing the same operations;
  • FIG. 6 is a vertical section showing the assembled brackets
  • FIG. 7 is a bottom plan view of the upper bracket
  • FIG. 8 is a top plan View of the lower bracket
  • FIG. 9 is a perspective view of an alternative embodiment of the invention.
  • FIGS. 10 and 11 are perspective views of machine showing the making and utilization of a device respectively;
  • FIG. 12 is a view of a machine similar to that shown in FIGS. 2 to 5;
  • FIG. 13 is a plan of the profile to be machined shown in FIG. 12;
  • FIG. 14 is a perspective view of a special device for the fixing of a pair of brackets on two parts of the machine.
  • FIG. 15 is a perspective view of a device for truing up or adjustment.
  • FIG. 1 shows schematically a spindle F of an electroerosion machine.
  • a cylindrical part B of the electrode can be fixed in a clamp G of the spindle F and the parts A to D of the elongated tool can then be advanced successively into a prepared hole in a work-piece P fixed on a table (not shown) of the machine.
  • the parts A to D of the electrode serve successively to machine the hole in the work-piece P in a manner becoming more and more fine and precise. It is difiicult to manufacture electrodes of the type as shown in FIG. 1 with precision, moreover, if the diameter of the electrode is very small with respect to its length. It is thus useful to replace the elongated electrode represented in FIG.
  • the device in accordance with the invention permits the subdivision of the elongated electrode shown in FIG. 1 into four electrodes, whilst avoiding the above mentioned disadvantages.
  • a first male bracket 1 is fixed in a perfectly specified position on the spindle F of the machine.
  • the tools or electrodes A to D are fixed in a position equally perfectly specified on female brackets 9 complementary with the male brackets 1.
  • the male bracket 1 is formed of a main body member 3 and a central tie-rod 4 fixed to the body 3.
  • the body 3 is in the form of a cylinder presenting a central bore 5 and comprising on its free end face several trued prisms 6, the axes of which are perpendicular to the axis of the body 3.
  • the body 3 presents four prisms 6 arranged at equal distances from each other on the face of the body 3; there could however, be conceived only three or a number greater than four.
  • Each of the prisms 6 presents two inclined faces 6a, 60 and a horizontal face 6b, the faces 6a, 6b and 60 being parallel to the axis of the prism 6 (FIG. 7).
  • a fourth face 6d is inclined with respect to the axis of the prism 6 and truncates this latter on the side of the axis of the body 3. This face 6d could, if necessary, be omitted.
  • the central tie-rod 4 is constituted by a cylindrical rod housed with play in the bore 5 of the body 3 and fixed to this latter by means of a cotter pin 7. There results by this method of fixing that the tie-rod 4 can lightly oscillate around the axis of the cotter pin 7, within the limits permitted by the diameter of the bore 5. As is seen in FIGS. 5 and 6, the central tie-rod 4 projects beyond the prisms 6 of the body 3 and presents a transverse hole 8 parallel to the cotter pin 7 near its free end. i
  • a lower face 10 of the female bracket 9 is trued to permit the adjustment of the tool, for example, by means of a screw or any other means of fixing.
  • the female bracket 9 is formed by a body L1 in the form of cylinder presenting a central bore 12 of diameter equal to that of bore 5 of the body 3'.
  • the body 11 presents a replica of the prisms 6 of the male bracket, that is to say hollow prisms 1-3 marrying exactly the form of the prisms 6.
  • the bases of the prisms 13 are hollowed more deeply at 14, this hollowing permitting the perfect application of the inclined faces 6a and 6b on the corresponding faces of the prisms 13 when the device is assembled.
  • the body 11 of the female bracket 9 presents several radial bores 15 (the number of which is equal to that of. the prisms 13), these bores 15 being tapped at 16 over a part of their length.
  • the axis of each bore 15 is directed in accordance with the bi-section of the angle formed by the axes of two adjacent prisms 13.
  • a barrel bolt :17 having a knurled head is adapted to be screwed inone of the bores 15.
  • connection between the male bracket and the female bracket is effected by means of a spindle 18.
  • This latter presents an end 19 of small diameter, adapted to be engaged in the bore of the barrel bolt 17, a central eccentric part 20 adapted to be engaged in the hole 8 of the central tie-bolt 4, a concentric part 21 of larger diameter, adapted to be engaged in one of the bores 15 of the body 11, and a head 22 traversed freely by a rod 23 at the ends of which are riveted two studs 24.
  • the female bracket 9 is applied against the male bracket 1 in such a manner that the hollow prisms 13- marry with the projecting prisms 6, then the spindle 18 is introduced into the bores 15 of the body 11 in such a manner that its end 19 penetrates into the bore of the barrel bolt 17 previously screwed into the opposite bore 15. It is clear that the axes of these two bores 15 must be chosen in such a manner as to coincide with the axis of the hole 8 of the central tie-rod 4. It then suffices to turn the spindle 18 in either direction with the aid of the rod 23 so that the eccentric part 20 is wedged in the hole 8 of the central tie-rod 4 and ensures an eflicacious locking of the two brackets 1 and 9.
  • the tie-rod 4 oscillates slightly around the cotter pin 7.
  • the axes of the two brackets are thus obliged to be perfectly aligned and the female bracket 9 takes up a perfectly specified angular position with respect to the male bracket 1.
  • each work-piece can thus be mounted on a bracket 9 in a perfectly specified position with respect to this bracket, so that the position of the work-piece with respect to the machine or with respect to the tools A to D is automatically specified when the female bracket carrying the work-piece is connected to the male bracket fixed on the table of the machine.
  • the bracket 9 carries a hollow electrode 25 subdivided in tWo parts 25a and 25b. In this manner, it is possible to conceive a slot 26 of irregular shape formed by two grooves in the parts 251:: and 25b.
  • the electrode 25 serves to form an electrode 27 by electro-erosion.-
  • the electrode 27 is fixed on a female bracket 28 which is connected to a male bracket 29 of larger diameter in the manner described above for the brackets 1 and 9.
  • the bracket 29 is fixed in a Well specified position on the table of the machine 30.
  • the spindle F with the devices fixed thereon is lowered until this electrode 27 enters into the hollow 2 6 of the electrode 25, so that the profile of the hollow 26 is reproduced on the electrode 27 by electro-erosion.
  • a single electrode tool 25 is shown in FIG. 9, several electrodes presenting hollows becoming smaller and smaller can be used successively to obtain by approximation the required profile of the electrode 27. It is equally possible that several electrodes 27 are manufactured successively with the same electrode tool or the same set of electrode tools 25.
  • FIGS. 10 and 11 show another example of the application of the process in accordance with the invention.
  • a cylindrical work-piece 31, already fixed on a female bracket 9 in a well specified position, is fixed in a planing machine by the assembly of the bracket 9 with a complementary male bracket 1 fixed on a divider 32 of the support of the machine tool.
  • the work-piece 31 is then machined to form for example a hexagonal pyramid. This pyramid can then serve as a tool in an electro-erosion machine, without being removed from the bracket 9.
  • the bracket 9 is separated from the bracket 1 of the planing machine to be fixed on the bracket 1 of the spindle F of an electroerosion machine in the manner indicated in FIG. 11.
  • the finished tool 31' which has already been fixed on the bracket 9 during its manufacture, is thus without further action fixed in a predetermined position on the spindle of the electro-erosion machine. Consequently, the tool is ready to be sunk into the work-piece P fixed on the base of the electro-erosion machine. As indicated above, the work-piece P can equally well be mounted with the aid of brackets 1 and 9.
  • FIG. 12 shows another application of the process in accordance with the invention, similar to the use in accordance with FIGS. 2 to 5.
  • it concerns the machining of a very complex profile, comprising profile parts I to IV in a work-piece P mounted on the table 30 of the machine with the aid of brackets 28 and 29 in the manner indicated above in FIG. 9.
  • These tools, designated by I to IV in accordance with the parts I to IV of the profile to be machined are each mounted in the corresponding positions indicated in FIG. 13 on female brackets 9 which can be successively connected with the bracket 1 fixed on the spindle F of the machine.
  • the exchange of tools and of prepared work-pieces P on the brackets 9 and 28 respectively, is simple and necessitates very little time.
  • male brackets 1 and 29 must be fixed on the spindle F and on the table 30 of the machine in a specified relative position.
  • This operation can be effected easily by means of an intermediate part 33 of the required length shown in FIG. 14, this part presenting hollow prisms such as the prisms 13 on both its ends.
  • This intermediate part 33 is inserted between the male brackets 1 and 29 facing each other in such a manner that the female prisms are applied narrowly against the projecting prisms of the male brackets.
  • the male brackets are then fixed in the obtained position.
  • the spindle F is then lowered until the bracket 29 rests on the table 30 of the machine in a well specified position with respect to that of the bracket 1.
  • the bracket 29 is then fixed on the table 30 in this position and the intermediate part 33 is then separated from the brackets 1 and 29. In this manner, it is extremely easy to fix the brackets 1 and 29 in the relative required position on the machine.
  • each tool is fixed on a bracket which is itself connected to a fixed bracket on the machine tool.
  • at least one exchange tool is prepared on a similar bracket and the position of this tool on the bracket is adjusted in advance in such a manner that the position of the tool, once its bracket is assembled with the bracket mounted on the machine tool, corresponds exactly to the prescribed position of the tool. It is thus possible to change one or several tools of the machine tool by semi-skilled personnel, whilst the skilled personnel can be strictly limited to the adjustment and/or the grinding of the tools outside the machine with appropriate auxiliary instruments.
  • FIG. shows schematically an example of such a truing device or adjusting of a tool.
  • a male bracket is fixed on a base 34 of this device, whilst supports 35 and 36 carry measuring instruments 37 and 38 feelers 39 and 40 of which are adapted to measure the limits of the point of travel 41 of a tool 42.
  • the tool is fixed on a female bracket 9 connected to the male bracket 1 of the truing device. To adjust a used tool, it sufiices to mount the bracket 9 carrying this tool on the bracket 1 and to adjust the tool 42 until the limits indicated by the instruments 37 and 38 correspond to the limits prescribed. The tool is then fixed on the bracket 9 in this adjusted position and the limits thus adjusted determine in advance the position that the tool will take when the bracket 9 is again connected to the bracket 1 fixed on the machine tool.
  • a process for removably fixing a device on a machine in a prescribed position comprising providing a pair of complementary brackets, said pair of brackets including a male bracket having trued prisms on its one end face with the trued prism surfaces inclined relatively to the general plane of said free end face and a female bracket having trued prismatic grooves of a shape complementary to the said trued prisms on its one end face and inclined relatively to the general plane of said one end face, fixing the one of said brackets to the machine in a perfectly specified position relatively to the machine and with its said end face fully accessible, fixing said device on the other of said brackets in a perfectly specified position relatively to said other bracket and with said end surface of said other bracket fully accessible, interconnecting said brackets with their complementary end faces engaging each other without clearance, the relative position of said brackets being thereby perfectly specified in three dimensions, the position of said device on the machine being thus perfectly predetermined by fixing it on said other bracket in a perfectly specified position and by interconnecting said brackets in a perfectly specified relative position.
