Description

The invention relates to a machine tool industry and can be used in vertical lathes for machining long workpieces.

The aim of the invention is to improve the processing performance and reliability of the machine.

Figure 1 shows the machine, a general view; figure 2 is the same, side view; on fig.Z - node I in figure 1.

The machine contains spindle headstock 1, caliper rack 2, drive 3 of the main movement, longitudinal caliper 4, side cross calipers 5 and 6 with tool adjustments 7 and 8. At the end of the spindle headstock 1 there is a fixture (cartridge) 9 driven from the clamp cylinder 10. On the longitudinal caliper 4 is fixed the center of the headstock 11 with the spindle 12, on the end of which there is a fixture 13, driven from the cylinder 14.

On the device 9 there is a stand-driver 15 with a key 16 fixed on its end. The device 13 is equipped with an axially moving half-coupling 17 with grooves a connected to the housing 18 by slots and held in the lower (working) position by three rolling pins 19 with springs 20 .

When moving the longitudinal slide 4 down the key 16 of the stand-driver 15 and the groove of the half coupling 17, as a rule, do not coincide, the end of the coupling half abuts against the end of the key, while the coupling half 17 compresses the springs 20 and moves upwards.

To ensure engagement of the half-coupling 17 with the key 16, the clamping device 9 receives rotation from the turning mechanism 21 mounted on the drive 3 of the main movement. Spindle 12 center headstock 11c clamping device

13 is fixed in a stationary position. When the axes of the groove and the coupling half and key 16 coincide in the process of turning the clamping device 9, the coupling half moves downward under the action of the springs 20, the key 16 enters the groove a, the spindle 12 is released. The workpiece is clamped.

After the workpiece is clamped, both devices 9 and 13 turn on the drive.

the main movement 3, cross supports 5 and 6 are fed with tool sets 7 and 8, and the workpiece is machined. Hereby, due to the presence of the key 16, the cutting force is perceived

at the same time adaptations 9 and 13.

The machine provides reliable basing and clamping of workpieces with large axial and diametrical sizes and an optimal balance between the forces

clamping and cutting.

Claims (1)

Invention Formula Vertical lathe containing spindle headstock with clamping a center head, a rack with longitudinal and lateral cross supports, a main drive, characterized in that, in order to increase reliability and productivity, the machine provided with an additional clamping device with a half-coupling mounted on the spindle end of the center headstock fixed on the longitudinal support, while the clamping device the spindle head is equipped with a half coupling with a key fixed on its end, intended to periodically interact with the coupling half of the additional jig set with the possibility of axial movement and associated spring-loaded rolling pins introduced into the machine. 1645061
