Description

FIELD: machine tool industry.

The purpose of the invention is to increase the reliability of work, the accuracy of rotation and fixation of the tool body on the base.

FIG. Shows a turret head, a sectional view; FIG. 2 is a section A-A in FIG. 1; Fig 3 is a motor shutdown mechanism; figure 4 - view B in fig.Z; in FIG. 5, the interaction of the pusher of the two shoulders with the sleeve Shes Garni J on FIG. 6 the interaction of the teeth of the cam clutch | in FIG. 7; the interaction of the flat gear of the tool housing with the toothed rim of the base

The revolving head contains a swiveling tool housing 1 with a tool holder fixed on it. The tool body 1 is mounted on a fixed base 2 and is equipped with a flat gear 3 designed to interact with the ring cog of the base 2. Inside the tool body there is a rotational drive containing a motor 4 with a reduction gear - gears 5-7 and sleeves gear 8 with a groove 9, Sleeve-gear 8 ,. transmits the movement to the tool case of 1 turret (phi1. 1).

The electric motor 4 with a reduction gear is installed in the guide cylinder 10, the revolving head is equipped with a gearbox, containing gears 11. The gearbox is installed in the additional housing 12, which in turn is installed in the guide: cylinder 0, One support of the gearbox is mounted at the base of the additional horn 12, and the other - in a removable cover 13 additional housing. The turret is clamped using a cam clutch, one of the coupling halves 14 of which is equipped with a Cylinder-gear 8 with a half-cam cam 14 continues to move relative to the stationary tool housing 1 and the cam half coupling 15. The tool housing 1 under the influence of the cam half coupling 14 and 15 goes down and fixed

on with a sleeve gear 8, and rubbed half

. coupling 15 - with the tool /: i50 body with flat toothed pair 3 and 2 (Fig. 7).

The positioning of the turret go-After the cams come out, the half coupling –– coarse search for the position –os-14 and 15 to the straight sections (FIG. 6) is realized with the help of an emphasis-fix-protrusion on the hub of the sleeve-8 pin 16, and the exact for a gear (fig ... 5) ,, hard; in zanb {according to the calculation of the crown of the base 2 and the flat gear-55 corner with the cam profile of the half-wheel 3. Lifting the turret go-coupling 4, presses the plunger 21 dexteries are produced under the action of a spring through a two-armed lever of 20 arms — ZH1CHNY 17 through a thrust bearing 18. on the limit switch 23 (ph gz)

The shutdown mechanism of the electric motor 4 includes a bracket 19 mounted on the tool case 1, and a two-arm lever 20, one arm of which communicates through toque 21 to the protrusions on the hub of the gear case 8, and the second arm is connected through a fixed screw 22. switch 23.

Unclamping and releasing the head and then turning the tool body 1 is performed as follows.

The rotor of the engine 4 rotates counterclockwise. Through the systems, the custer rotates the casing-scestern 8, with which the upper cam of the coupling half 14 rotates (Fig. 6), the cam hollows of the coupling half 14 are mounted against the cam lips of the coupling half 15. The released tool housing 1 with a flat gear wheel 3 rises under the action of the spring 17 up, release the turret. The engaging cam of the half-coupling 15 with the cam of the coupling half 14 of the sleeve gear 8 begins to turn the tool housing 1 counterclockwise until one of the four radial grooves of the coupling half 15 goes around the circumference 4- 5 beyond the fixing plane of the support-clamp 16.

At the same time, one of the four limit switches for position 24 (Figs. 1 and 2) is pressed, corresponding to the 1CH of the indicated notch, and the rotor rotation of the electric motor 4 is reversed. When moving back stop 16 sit down: mc on the right bevel of the notch. The tool body 1 is stopped.

The sleeve gear 8 with the cam of the half-wheel 14 continues the movement of the relatively stationary tool case 1 and the cam of the coupling half 15. The tool body 1 under the influence of the cam of the coupling half 14 and: 15 goes down and fixed

timely turns off the reverse of the engine 4, not allowing it to stop at the emergency stop 25.

Providing a fixed shutdown of the electric motor after reversal, the device guarantees the stop of the gear sleeve 8 or at some point in the direct part of the half-coupling 14, not income from the wall 9 to the emergency stop or bringing it to inertia

With a small force, I don’t cause an overload of the system of turret gears.

Ko1; the clocks of the end switch 23 are turned on only during the fixing and clamping of the head after searching for the desired position, and at the rest, the time of the tool housing G and the sleeve gear 8, while rotating, does not give a relative displacement.
