FIG. 2

The invention relates to a machine structure and can be used in lathes of the turning group.

The aim of the invention is to increase productivity while reducing the size of the machine.

Figure 1 shows the automatic lathe, front view; figure 2 is a view of And figure 1,

The machine contains a stationary spindle head 1 with an axis 2 mounted on a bed, a front cross support 3 with a rest 4, a rear cross support 5, a longitudinal support 6 with a turret 7 mounted on a longitudinal support 6, with the front side 8 of which is located in diametrically located sockets the counter-spindle 9 and the cartridge 10 for the end tool 11 are mounted, the sockets of which are diametrically opposite to the circumference with a diameter d, the axis 12 of the turret is from the axis 2 of the spindle head 1 at a distance equal to half the diameter d / 2 of a circle. In the turret 13 rear cross slide 5 on the end surface

15 of the end tool 16, coaxial to the chuck 10, the end face 14 and the cartridge 15 face the end surface 8 of the turret 7, Kotor also has tools located on its face.

Front Phillips Caliper 3 Prov. a cap with a turret 17, on the top of which are placed cartridges for mounting the cutting tool. ,

The lathe is controlled by a CNC device (not shown). Automatic lathe works as follows

A bar clamped in the main spindle of the headstock 1 passes through the rest and can be simultaneously processed by three tools: Two tools with turrets 13 and 17S mounted on the faces of the rear cross support 5 and front cross support 6, respectively, and end tools 11, mounted in the chuck 10 of the turret 7 of the longitudinal support 6. After machining the part in the main spindle, the revolving head 7 rotates the star of the axis 12 so that opposite to the part

There is a counter spindle 9 with a clamping device. After the anti-spindle 9 clamping device, the part is cut off, the revolver head 7 is rotated again around axis 12, and the part is transferred to the processing line with end tools 16 of the turret 13, while the next part enters the main spindle. Further, it is possible to simultaneously process the previous part, clamped in the counter spindle, on the reverse side with end tools 16 and the next part, clamped in the main spindle, with tools of revolver heads 17 and 7.

The proposed automaton allows to combine processing in one working zone of a part located in the main spindle, three working bodies (two cross supports and a longitudinal support), and parts that are in the counter-spindle, two working bodies (one cross support and a longitudinal support ). This makes it possible to increase the production of the automat of the automaton in comparison with the known one by 1.3 times. The overall size of the automat is reduced by 20% in comparison with the known one, due to the fact that the machining of the part in the main spindle and the part in the antispindle is performed in one working zone.
