Description

Known are multi-spindle myoiOzioznonnys uojiyaivroMaTiiMcc boring machines of the carousel type with radial razggolon yenisa spindles, spabzhennymi common central drive gear and automatic rotary devices for the installation of parts on a separating rotary table. However, they are large in size and difficult to maintain.

In the machine described, the spindles are spaced from the center of the table but towards the fixtures installed on the cantilever rolling pins along the outer circumference of the table, which makes it possible to reduce the size of the flock and simplify the maintenance of the fixtures during operation.

FIG. 1 shows schematically the described machine in longitudinal section; in fig. 2 is the same, top view. With a partial cut.

From the electric motor, through a worm pair / rotation, is transmitted by a pinner P1ester e2 mounted on a shaft. On the table 4, spindles 5 with spindle heads 6 are placed but to radii from the center of the table. Spindles 6 together with bushings 7 in which axial movement of spindles takes place 6, rotate from bevel gear 2 through gear 5, shaft 9, and a straight pair of gears W.

In the head for threading, the spindle hub lies from the gear 8 with the shaft // through the included gear coupling 12, the shaft J3 and a pair of gears M. When the coupling with the conical gear J5 is turned on, the shaft 3 begins to rotate in the opposite direction.

The coupling is switched using a dual solenoid 16 while the spindles are being fed by the handle 17 through the contact sensor 18 and the lever / 5. The feed of the spindles 6 is carried out by the cams 20 fixed on the pipe 21 rotating from the electric motor of the noMonui of the worm bunk 22 and the scraper 23 and 24.

 i. 33316 2 From a pair of worm gears 22 through a pair of gears 25, shaft 26 and drive 27 receives rotation 16-slot Maltese cross 28 mounted on hub 29. Console rolling pins 30 are fixed in the holes of bushing 29, on which the outer circumference of the fixed table 4 is placed automatically turning devices 31 in which the workpieces are fixed. The automatic rotation of the tool 31 of the probe is done next, after the holes have been completely machined on one side, and when moving from the last position to the loading device 31 with the workpiece, it returns to its original position.

Multi-spindle multistage semiautomatic drilling machine of a carousel type with a radial positioning of shafts, equipped with a common central drive and automatically with new tools for mounting parts on a pivoting rotary table, so that, in order to reduce the dimensions of the machine and simplifying the maintenance of devices during operation; the spindles are exchanged from the center of the table towards the devices installed on the cantilever rolling pins along the outer circumference of the table. tzhsh
