Definitions

  • the present invention relates to turret-heads for machine tools and the like, and more particularly to means for indexing and clamping the turret-head selectively in a plurality of positions for holding the tools in relation to the work piece.
  • An object of the present invention is to provide a device of the type above mentioned, which is simple, and reliable and which can be operated smoothly and quickly, involving only natural movements for the man who controls the machine.
  • Another object of the present invention is to provide a mechanism which, in view of its great simplicity, is not very costly to manufacture and eliminates any risk of breakdown.
  • a characteristic of the present invention lies in the utilization of kinematic devices which provide for speed reduction, which permit operating the machine smoothly and without having to apply great effort, and the operation of which is effected in four steps by means of a single lever and in the following manner:
  • 2nd step movement of the lever preferably toward the turret-head, in the direction parallel to the axis of the turret-head so as to ensure the unlocking thereof;
  • 3rd step rotation of the lever about the axis of the turret-head in the same direction as above which secures unclamping of the turret-head, while the lever is kept for a short time in the position to which it was moved inthe second step in order to move the turret-head from one locking position to another to bring a new tool into operative position so as to produce the displacement of the turret-head.
  • Figure l is a transverse section of the turrethead control devi-ce constituted according to one embodiment of the invention.
  • Figure 2 is an elevation taken from the right in Figure l.
  • Figure 3 is a sectional view on the line IV-IV of Figure l.
  • the control device for turrethead I mounted on arm 2 of the machinetool includes a single lever 3 which permits of ensuring, under conditions which will be hereinafter set forth, the unclamping, the unlocking, a displacement of the turret-head corresponding to one or several sections and indexing this turret-head in the new position, and the reclamping of said turret-head in the new position.
  • This lever 3 is mounted on a pivot pin ll, itself carried by a rotatable piece 5 which is capable of turning about the axis :1J-y of the turret-head which is at a right angle to the axis of the lever 3 and to the plane of rotation of turret-head I.
  • Piece E is threaded at il on the hollow shaft 'I.
  • control rod 8 is slidably supported and is provided at one of its ends with a sleeve 9 provided with circular rack teeth and kept in position by means of a nut It.
  • This sleeve 9 meshes with the teeth lI carried by a hub I2 rigid with lever S.
  • rod 8 carries a pin lli engaged in a fork'lli provided at the end of a lever l5 adapted to pivot upon a stud It.
  • lever E5 carries a finger I7 which engases in a slot of a locking piece I8 which, in the position shown in Figure 1, serves to lock turret--head I in position owing to the fact that said piece I8 engages in one of the notches i9 provided in the ⁇ tu.rrethead.
  • the turret-head at its left hand face is provided with as many notches l@ as there are different positions to be occupied by said turrethead by rotation thereof on the shaft l.
  • Rotary piece 5 carries, at its inner end, shoes 23 which come, when the turret-head is clamped, to bear strongly against the front surface of a flanged piece 2A fastened to turret-head l.
  • a pawl 2 In order to permit of rotating turret-head l, I make use of a pawl 2, Figs. 1 and 3, which is mounted on pin 28 fastened in rotary piece 5.
  • This pawl can come into mesh with a ratchet wheel Z9 fixed on a toothed wheel 3i). Toothed wheel @il meshes with a pinion 3
  • lever 3 When lever 3 is turned through a certain angle, for example, in a counterclockvvise directionl 2, it rotates piece 5 which is screwed at 6 on fixed shaft l. This effects unscrewing movement and serves to bring bearing shoes 2S away from turrethead l and therefore produces the unclamping thereof.
  • the toothed wheel 3B which is xed to this ratchet wheel is thus caused to rotate and consequently drives pinion 3l, whereby toothed ring 32 which is rigid with the turret-head is caused to rotate.
  • the turret head is thus driven in the particular embodiment being described in a direction opposed to that of lever 3 ⁇ because of the intervention or" the internal gear train 30, 3
  • the device according to the invention which has been shown in the drawing, by way of example, as applied to a machine tool, such as a vertical lathe having a single upright, may be applied to any other kind of machine-tools and to any machines or apparatus where a turrethead is utilized.
