  • the present invention relates to a machine for the high speed, mass production with extreme precision of small pieces with complex forms such as: electric contacts, screws, horological pieces, carburettornozzles, breaker contacts, special pieces for cameras and delicate equipment .or apparatuses and in general metallic small articles.
  • the machine according to the present invention may be rapidly adapted to produce with very high precision (tolerance of the order of the microns) articles of very small dimensions and complicated forms which are different one from the other. Furthermore, the machine of the invention is so devised as to make it possible to change, with great rapidity and within a wide range, the working speed while maintaining constant the speed at which the articles are fed from one working-station to the next one. This feature is responsible for a considerable increase in the production and, as a consequence thereof, for a and being fixable to the outer stationary frame coaxial to the central shaft;
  • secondary members which displace angularly to itself the axis of each workpiece-carrying di'sc so as to bring the same into the right working position and means to fix the same in exact position before starting the working process; said discs being so shaped as to permit working with chucks placed below and above same.
  • FIG. 1 is a diagrammatic axially sectioned view of said machine.
  • FIG. 2 is a cross-sectional view of 'F IG. 1 taken along the plane passing through AB to illustrate the details of the members controlling the stepwise movement of the considerable reduction of the cost of the finished articles.
  • main members which intermittently move said turntable to pass from one working station to the next one in the shortest possible time;
  • tool-holding chucks situated in each working station and disposed above, at the side of and under the periphery of said turntable in correspondence to each workpiece, said chucks having their working movement imparted thereto by groups of peripheral cams (i.e. disposed at the periphery of the turntable between one station and the next) as well as by a group of axial cams (i.e. disposed along the axis of the turntable) with possibility of simultaneously operating on the pieces with at least three chucks for each workpiece-carrying disc, said chucks having their axes differently disposed and orientable as a whole over an angle of about 200 turntable carrying the pieces to be worked on.
  • FIGS. 3, 4 and 5 are detailed axially sectioned views of the same members.
  • FIGS. 6, 7, 8, 9, 10, 11 are views of details of the damping devices for the means driving the turntable as well as of the tappets and of the tie rods.
  • FIGS. 12 and 13 are details of the device for rotating the discs carrying the grippers holding the workpieces, said discs being distributed at the periphery of the turntable.
  • FIG. 14 is a plan view of the device actuating the main shaft.
  • FIGS. 15 and 16 are views of an actuating device for the turntable with a direct current motor, the speed of which is electronically controlled.
  • FIGS. 17 and 18 are views of a mechanical device to increase the displacement speed of the turntable.

  • FIGS. 29 and 30 are views of a roller device for feeding and straightening the raw wire horizontally inserted in the self-centering grippers.
  • FIGS. 31 and 32 are views of a device to charge the corresponding self-centering grippers with pressed, stamped, pre-turned or in any other way pre-shaped rough pieces or blanks.
  • the main motor 3 (FIG. 1) situated in the base frame 1 drives, by means of a belt speed-varier, the worm wheel 4 and therewith the main shaft 5.
  • This shaft actuates in its turn, through the toothed wheels 6 and the bevel gears 7, the groups of lateral cams 8 situated outside of each lateral surface of the hexagonal casing 2 (see FIGS. 2 and 14).
  • the groups of lateral cams 8 situated outside of each lateral surface of the hexagonal casing 2 (see FIGS. 2 and 14).
  • the stepwise rotating turntable 16 is fixed to the intermediate rotating bush l8 and is intermittently operated by the secondary turntable 9 illustrated in FIG. 2, in the following manner:
  • the first cam 19 which is provided in the secondary turntable 9 actuates by means of the roller 20 and the levers 21, 22, 23 the central oscillating lever 24 (see also FIG. 1) which is mounted idle on the central shaft 5 so as to impart to said oscillating lever an oscillatory accelerated and decelerated motion, the amplitude of which corresponds to the angular displacement which is to be imparted to the stepwise rotating turntable 16.
  • the lever 23 (FIGS. 2, 3) carries at its end a fork member 23' having the slide 191' (FIG. 5) sliding therein.
  • Said slide 191 is pivotedon the lever 22 (FIG. 2) and is connected to the bush 193 (FIG. 4) by means of the rod 192.
  • the body 195 (FIG. 4) fixed to the fork member 23' (FIG. 5) of the lever 23, is resiliently connected to the bush 193 through the balls 194' situated in the holes provided in the above mentioned body 195.
  • the balls 194 are pushed by the sleeve 190 and by the spring 196 into the groove 193 ofthe bush 193.
  • the joint acts as a rigid connection member.
  • the component of the forces acting through the balls 194' between the bush 193 and the sleeve 190 would overcome the counterforce of the spring 196; the bush 193 would then move with respect to the body 195 so that the balls would leave the groove 193.
  • the force would then practically fall to zero so as to prevent any damage to the mechanical parts.
  • the sleeve 190 displaces the block 200 and disconnects the switch 201 which, in its turn, acts on the emergency brake.
  • the threaded nut 197 it is possible to exactly set the oscillating lever 24 (FIG. 3) so that the piston 25 is positioned with great precision withrespect to the complementary pins 18' protruding from the intermediate bush 18 as it will be better explained later on.
  • the clamping device 198 (FIG, 2) is provided for damping the whole system.
  • the lever 24 carries the small piston 25 which is vertically displaced by the doubleacting cam 26.
  • the small piston 25 By moving upwards, the small piston 25 enters with its conical opening 25 into one of the complementary pins 18 protruding from the intermediate rotating bush 18.
  • the double acting cam 26 lifts the small piston 25 in the forward moving phase of the oscillating lever 24 and therefore of the stepwise rotating turntable l6 and lowers the same in the return phase of the oscillating lever 24.
  • the small piston 25 actuated by the double acting cam 26 is provided with a damping device.
  • Said damping device comprises a cylindrical body 45 (FIGS. 6, 7, 8) pushed upwards by the springs 49 which act on the body itself through the small plate 47 and the balls 48 (see the detailed construction in FIG. 7).
  • the cylindrical body 45 enters into the conical pins 18' of the sleeve 18 (see FIGS. 1, 3, 6) and, to obtain a perfect tightness without any clearance, said cylindrical body 45 must resiliently adapt itself to the associated
  • the cam 26 imparts to the cylindrical body 45 a stroke some tenths of a mm. larger than normal so that the springs 49 also are compressed thereby some tenths of a millimeter.
  • the cylindrical body 45 undergoes an elastic yielding along the whole length of its projecting part, without however exerting a force great enough to be harmful to the machine.
  • a further advantage consists in that the displacement of the small plate 47 and of the springs 49 is less than half of the displacement of the cylindrical body 45.
  • the small plate 47 has fixed thereto a pin 47', which actuates in case of accidental phase displacement the lever 50 which, in its turn; controls the electric contact 51 by means of the magnet 85.
  • the contact 51 activates the emergency brake.
  • the tappets controlling the work stations are provided with release damping devices as illustrated in FIGS. 9 and 10, comprising a hollow cylinder 41 and a coaxial stem 42; the balls 40 are pressed in the groove 42 by the sleeve 44 and by the spring 43.
  • the stem 42 stays thus positioned with respect to the hollow cylinder 41.
  • the tappet behaves like a rigid body.
  • the balls move outwards displacing the ring 44 and compressing the spring 43.
  • the stem 42 remains therefore free to slide in its axial direction practically without any strain.
  • the advantage of the device consists in that, once the maximum allowable stress has been exceeded, the axially acting force practically falls to zero.
  • FIG. 11 illustrates a tie-rod functioning on the same principle.
  • the rotating turntable 16 with its gripper-carrying discs 17 (FIGS. 12 and 13) is so designed and constructed as to permit the fixing of the working centers each comprising, for instance, up to three chucks with the associated independent electric motors which may be fixed vertically above as well as vertically below the turntable itself. However they may also be fixed horizontally or so as to form any angle comprised between and 200.
  • the rotating turntable 16 is provided at its periphery with a plurality of holes to contain the gripper-holding discs 17.
  • said discs 17 may be rotated through a certain angle while passing from one working station to another.
  • the toothed wheel 32 fixed below the gripper-carryingjdisc 17 engages during the rotation of the turntable 16 the toothed segment 33 fixed to the machine body, thereby imparting to the gripper-holding disc 17 a rotation through a certain angle.
  • Said angle depends on the number of teeth of the segment 33. By varying the number of teeth of the segment 33 is thus possible to vary said angle.
  • the gripper-carrying discs 17 are blocked relative to the rotating turntable 16 by means of the rods 15 (see also FIG. 1).
  • the rods serving to block the discs 17 and the rods 14 serving to block in the desired positions the rotating turntable 16 are controlled by the cam 10 fixed to the secondary turntable 9 fixed, in its turn, to the main shaft (FIG. I).
  • the double acting (in both directions) cam 10 controls the disc 13 through the rollers 11 and the rods 12.
  • Said disc has fixed thereto a certain number of said rods 14, 15 which, by moving upwards, fix or set the position of the rotating turntable l6 and of the gripper-carrying discs 17, as mentioned above.
  • rods 14 block very firmly and rigidly the rotating turntable 16 by passing though the outer stationary frame 193, through the inner stationary sleeve 194 as well as through the intermediate bush 18 rotating together with the turntable.
  • the rods 14 (and 15) move axially, penetrating into bushes provided with ball rings which are resiliently compressed by the rods.
  • the control of the working centers is effected by the already mentioned groups of cams 8 disposed at the side of thehexagonal frame and acting by means of tappets, as well as by the groups of cams fixed to the upper end of the central shaft (see FIG. 1).
  • the ratio of the gear pairs 6, 7 are so chosen that the shafts carrying the groups of cams 8 have a ratio 1/1 with respect to the central shaft 5 and furthermore so that the number of teeth of the central bevel gear 7 is a multiple of thenumber of cam groups so as to allow for a ready phase setting.
  • the main motor 3 (see also FIG. 1) actuates, through a speed varier, the shaft 27 which, in its turn, actuates the shaft with the helical gear 4, through the electromagnetic coupling 28.
  • the shaft 27 carrying the helical gear 4 is furthermore provided with an electromagnetic brake 29.
  • the shaft with the helical gear 4. has coupled to its other end, through a further electromagnetic coupling 30, another motor 31.
  • the coupling 29- is connected to block the shaft 5 in case of emergency stopping.
  • the shaft 5 can rotate at two speeds: a first speed :1 imparted by the motor 3 and variable by means of the varier, and a second speed n imparted by the motor 31.
  • connection of the electromagnetic couplings is controlled by a contactor which in its turn is controlled by one of the cams 8.
  • the rapid change from one higher speed n to a lower speed n may be obtained by means of a dynamic braking process according to which the direct current motor acts as a generator until the speed n has been reached.
  • the circuit is diagrammatically represented in FIG. 16.
  • the motor 52 has a generator tachometer 53 coupled thereto which produces a potential which is directly proportional to the number of revolutions of the motor.
  • the rotational speeds are preselected by means of the potentiometers 54, 55.
  • a commutator 63 controlled by one of the cams 8, effects first one and then the other of the preselected speeds.
  • the electronic circuit 64 comparesthe potential of the tachometer with the potential of the inserted potentiometer and controls, as a function of said potentials,
