The invention relates to a machine tool industry and can be used in machine tools tina turning center, equipped with a tool shop.

The purpose of the invention is to expand technological capabilities.

FIG. shows a lathe with automatic tool change, a general view; on . 2 - lathe, pitchfork from the right torn; in fig. 3 - lathe with tool tip, view in nlan; in fig. 4 is a section A-A in FIG. 2; in fig. 5 section B - B in FIG. 2

The automatic tool changer lathe contains a bed 1 (Fig. 1), on which the headstock 2 and the back headstock 3 are placed, a non-processed work piece (not shown).

On the upper plane 4 of the frame 1, the maneuvers for moving n1K) of the subalong sunnort 5 are arranged, on which transverse support 6 is mounted with a rotating holder 7 mounted on it for tools that are exchanged in holders 8. Also on the plane 4 in two brackets 9 a cylindrical guide 10 for joint non-lugging is attached (TSNI with a longitudinal sunport 5 podvpzh-NON1CH); 1 8 holders, made in the form of a shop of 1I tools. The cylindrical guide I) is located in the location of the projection of the center of mass of the store 11, which results in unloading the sunnort 5 and its hinge 1, they are from the weight of the store 11. At the same time, the shop 11 is installed with its axial passage beyond the headstock 2, which ensures unhindered access of the tool, in the swivel holder 8, to any point of the product.

To jointly move the tool magazine 11n longitudinal caliper 5, a driver 12 is provided (Fig. 2, 3, 4), fixed on the caliper 6, and a protrusion included therein, for example, in an ideally circular segment 13, fixed on the case of the magazine I, and the centering axis of the guide 10. The spontaneous tilting of the magazine is eliminated by locking the angular position of the magazine's cornea, executed in the form of the locking pin 14 (Fig. 2, 5) entering the slot made in the caliper 5. For near cheng1 1 store change 11 nredusm the special stand 15 (fig. 2) and the angular displacement drive (not shown) of the magazine 1 1 relative to the guide 10, which is the axis of its angular non-slidability, as well as the axial displacement drive of the fixing pin 14 (Fig. 5 ), vn, 1nnny, for example, in the form of a norsch 16, entering the cylinder located in the caliper 5. On the same caliper is installed with

rotatable, longitudinal and fixed in three predetermined means 17 for overloading the tools (extreme right position setting of the holder 8 to the holder 7; medium; undetectable - turning the magazine 11, searching for) 8; The leftmost position is to install and remove the holder 8 from the magazine. eleven).

The lathe works as follows.

A set of holders 8 are installed in the slots of the magazine 11 with the tool necessary for processing the product fixed in the centers or the stern of the headstock 2. The tool 17 is used in the holder 7 but the program installs the tool required for the first operation and turns on the rotary actuators product and displacement support 1 and oi are the CNC pins to be machined with the first tool. When the caliper 5 moves, the shop 11 moves together with it along its own guide 10. When the nerve (as well as subsequent operations) is completed, the tool 17, regardless of TOi O., in which position the caliper 5 takes, takes the holder from the holder 7 and longitudinally moves moves it to the extreme left position, then rotates and installs it into the free slot of the magazine 11, after which the tool 17 takes the average value and the magazine rotates, setting the following necessary D.L. 8. which, by means of means 17 (longitudinal course to the left, turning and then longitudinal course to the right) is placed in holder 7. The latter, depending on the operation performed after fixing the tool-14), takes the required position (pa, i; ie; ibHO or perpendicular.1 ppo axis penn) C |.
