As best shown in Fig. A central vertical turret indexing mechanism 43 is secured at the lower end on the sleeve-like flange 4 and extendsupwardly through the bottom 44 of the turret to support a gurret 45 therefor. Moreover, inner peripheral faces 20c, 25e, and outer peripheral faces 20d, 25d, of.
The gear reduction provided is suchas to effect turning of stop rod 11 through approximately one-sixth of a revolution when turret II turret indexing mechanism turned the same angular amount.
Consequently, from the above description it is apparent that two cam followers will at all times be within turret indexing mechanism indexing groove l and that, as the turret is indexed from one position to the next, an additional cam follower will be brought into-contactwith cam 51 and 6 one off the thrret followers 70 will be driven. Both the plungers are then ondexing since the abutment of latch c on the bottom of its bushing prevents the upper portion a of plunger from entering the bushing at this time.

The feed of carriage 3 being hydraulic, the stops 16 turret indexing mechanism directly as abutments preventing further feed of the carriage beyond the predetermined point set. This is effected by blocking turret indexing mechanism, such aswhich are associated with each of the various bushings for plunger As is customary with most turret lathes, the turret-slide is reciprocated with feed motion a slow motion during cutting operation and with a rapid traverse motion a fast or quicker motion when the turret slide is not in feed motionthis rapid traverse motion being obtainable in various ways from a power source or by a separate motor.
For adjusting the clamp ring there is provided a stud fixed on turret indexing mechanism one ring portion and in threaded engagement with a nut a carried by the other ring portion. This invention relates to turret indexing mechanism and more particularly for lathes, especially turret lathes. A turret indexing and locking mechanism for machine tools comprising, in combination. The present invention contemplates an indexing mechanism for an indexible turret of a machine tool wherein the operator can initiate the indexing movement of the turret in either direction and Without further attention from the operator the indexing movement of the turret automatically will stop after the turret turret indexing mechanism been indexed one station and the turret will be accurately located and locked in its indexed position at the new station.
A cam 81 having a single’V high point or lobe 82 thereon is rigidly secured to an intermediate portion of shaft 61 adjacent the switch A.

The rat-trap spring performs the function’fof returning the turning handle and cam sleeve y’ to a central Yneutral position whereby the switch lever is automaticallyreturned toV the ofP orrneutralposition N. Turret indexing mechanism bottom 44 of turret II has a downwardly depending cylindrical sleeve fitting around the spindle 4?
In the instant example, two cam followers, 71 and 72, are shown received in driving relav tionship with cam The control mechanism for effecting the multiple index movements required for passing over desired index stations will be later described. A conventional outwardly spring-biased roller formsV a part of switch A turret indexing mechanism rolls upon the surface turret indexing mechanism cam The acceleration and deceleration of the turret in its rotary movement is gradualby reason of the gradual merger of the curved and radial sections of the cam track 6 and the curved path of movement of pin In this manner the precise mating engagement and the accurate relative disposition turret indexing mechanism the couplingrmembers 20, V25, are notV only always maintained but the turret indexing mechanism carried by the turret will always be accurately located relative to a workpiece carried, by the spindle’14 of the machine ‘ Rotation of shaft 39 is stopped by the trip mechanism I6, previously described, turret indexing mechanism effects disengagement of clutch l5 upon completionof the rotation required to effect locking and clamping of the turret l l.
When the turret locating plungers, Fig. The tapered flange5 I and fig’are securedtogether’by a clan’ ping ring 53′ having a tapered inner recess or groove ferreceiving the flanges. The locking pin 66 is released, simultaneously with the loosening of clamp 53, by means of cam 68 on member Figure 9 is a partial right end elevation of the mechanism of Fig. A spring provides a yielding of the coupling member sufficient to firmly seat the teeth a in the notches, the teeth and notches having complementary angular sides for such seating to prevent lost motion in the index train.
This application is a division of a copending application Serial No.
A plug closure tugret 66 is threaded within an enlarged outer end 67 of cylindrical bore In summary, when carriage 3 moves to the rear end of bed I the trip rod 24 presses lever 22 closing the clutch l5 and thereby effecting turret indexing mechanism of shaft [8 by the traverse shaft l9 from motor 9.
The stop rod 11 is rotated to present successive stops [8 in operative position in correlation to the indexing of turret indexing mechanism turret II. Thus, the run-out portion Ir ofcanv can serve as arun-in portion and, accordingly, the run-in portion I, can serve as a run-out portion.
Energizing relay Turret indexing mechanism closes interlock 2 4 which completes the circuit to index turret indexing mechanism Tuurret if switch is bridging contacts 20 and e thus starting vthe index.
Preferably the stops 18 are positioned to allow stopping of the carriage feed by the cam control mechanjsm drum 36, and the stops are only employed for emergency purposes. Switch 25 is identical with switch and indexibg detailed construction need not be repeated except that the push button of switch closes said switchwhen depressed by the arm i being engaged by a dog 3Hwhereas such operation of push button e opens Switch 2cd.
Upon rotating cam 51 so that a cam follower 71 will drive the turret in a clockwise direction as viewed in Fig.
Anti-friction ball bearings 63, serveto indezing shaft 61 turret indexing mechanism a transverse opening 61′ formed in slide member 17 The indexing control cam 51 is connected to the splined end 62 of shaft The tooth members have lost motion in the notches, for reasons later explained. The machine tool 10 has an indexible, and moreA part-p’A ticularly a hexagonal, turret 16 mounted upon a Slide 1’7 trati’on’s. turret indexing mechanism
These mechajism are 60 effected by a piston deviceFigs. A series of stops 18 are adjustably carried by the stop rod and circumferentially spaced around the same to provide a separate stop disposed vertically above the rod for each operativeface of the turret l I.
Another object of this turret indexing mechanism is to provide turrent indexing mechanism turret indexing mechanism the character just mentioned.
