This invention relates to a machine tool.

A software-controlled lathe containing longitudinal slides carrying several transverse calipers with tools is known, interacting with a displacement drive through a reduction gear and a self-centering mechanism made in the form of a disk, on the end surface of which a helical cutting is used, which interacts with gear racks mounted on transverse calipers.

The disadvantage of the known machine tool is that all the tools installed in the cross supports simultaneously participate in the work. This allows machining a part only with identical tools (for example, through cutters) or by a combination of them that allows their simultaneous use (for example, through cutters and subsequent breakers).

The aim of the invention is to expand the technological capabilities of the machine.

The goal is achieved by the fact that a software-controlled lathe containing longitudinal slides carrying several transverse calipers with tools driven in the form of a downshift and a self-centering mechanism made in the form of a spiral disk interacting with the transverse caliper racks is equipped with an additional set of transverse calipers with slats, placed on the peripheral part of the spiral disk, on which additional cutting is made, intended for interlocking Modification with slats additional transverse calipers.

FIG. 1 schematically shows a machine, a general view; in fig. 2 is a view A of FIG. 1; FIG. 3 - section BB in FIG. 2; in fig. 4 - spiral claim.

The machine contains a bed 1 with a longitudinal caliper 2 mounted on it, a front 3 and a back 4 headstock. In the spindle of the 5th front of the head, the leading center b is behindsable, and in the tailstock in the tailstock - rotating

center 7. On the cross slide 8 by means of a bracket 9, screws 10, 11 and 12 a housing 13 is installed, carrying transverse supports 14. The sup5 ports are located in the radial grooves of the housing — equal angular intervals and divided into two sets, each with There are various machining tools 15 and 16. Each kit can have any number of transverse supports that are symmetrically located relative to the axis of rotation. The case has a spiral

15 a disk 17, on the peripheral part of which the spiral cuttings of opposite directions, separated by an annular groove, are made. Transverse calipers carry gear racks located on each of the sets of transverse calipers in such a way that they can interact with only one of the spiral cuts throughout the entire working range of caliper movements. The disk 17 is kinematically connected to the drive shaft 18, manually operated from the handle 19 or from the drive 20. The kinematic coupling is carried out through

A 30 worm pair, including a worm gear 21, mounted on a shaft 22 installed at one end in a longitudinal slide by means of a support 23, and a second end with a square section i4, interacting with a bevel gear made on a helical gear the disk 17, and the screw to 25, mounted on the drive shaft 18. The cutting tools 15 and 16 are fixed on the cross slide with 14 screws 26. Combining machining tools, installed

Five of them in a housing set of cross calipers may be different, for example, one of the sets contains feedthroughs, and in the other - cutting tools, or in one

50 checkpoints, and another threaded, etc.

The machine works as follows

Two,; a set of processing tools 15 and 16 set 5 on the respective transverse supports. As in each set. tools are simultaneously involved in the work, they need to be configured as follows. to evenly divide the stock between all the tools in the set. The allowance can be divided both by depth of cut and by feed. Tools can be adjusted using a special tool or a control mandrel. After adjustment, the tools are set to their original position, from which all movements envisaged by the treatment program are calculated. Next, the workpiece 27 to be processed is fixed and secured, and the program operation of the machine is activated. At the same time, first from the shaft 18, through a worm gear and a bevel gear, a spiral disk 17 is rotated, which by means of spiral-rack gear engages transverse calipers 14 in the radial direction. Since the slats of cross calipers included in different sets interact cutting, the transverse supports of one of the sets are moved towards the part, the supply of the corresponding tools to the working position, and the second set - vice versa. Then, in accordance with a given program, the longitudinal slide is moved and the first stage of the part is processed. If the program is followed by processing a second stage of a different diameter, then the transverse calipers move again in the radial direction to the appropriate distance and again processing is performed by moving the longitudinal caliper. The process is repeated as many times as the steps on the workpiece. Then, by moving the longitudinal and transverse supports, the tools of the second set are reset. In this way, they are fed to the working position and are machined with the part. The proposed machine provides the expansion of technological capabilities by increasing the number of operations performed, increasing the processing capacity, especially in the manufacture of parts with rigidity.
