    The invention relates to a tool collector for machine tools, including, in particular, digital software control machine tools.
    The purpose of the invention is to increase productivity and increase storage capacity.
    The invention is illustrated in the drawings, in which: FIG. 1 shows schematically a tool storage device. cops, side view; in fig. 2 - the same, top view; in fig. 3 — tool storage box, longitudinal section with a tool magazine held by a gripping device in the loading and unloading position; Fig. 4 shows a tool storage device, a longitudinal section showing the function of an additional gripping device.
    kdl fixing the tool magazine on the rotor; in fig. 5 is a depiction of individual devices for gripping the tool storage device; Figure 6 is a top view of a tool storage for explaining its operation; in fig. 7 - tool shop with a tool installed in it, a cut; in fig. 8 - tool storage with a rotated tool magazine. The tool storage has a cylindrical column around which there are a number of shops 2 tools located adjacent to each other in the form of a ring around the axis of column 3. The shops of 2 tools run axially parallel to the axis of column 3 and have some quantity of 00 00

    located in a row of sockets 4 for tools in which tools 5 with holders of 6 tools are installed with a radial arrangement. At the ends of the 2 tool shops, there are gripping plates 7, which can also be used for coding.
    From FIG. 2 it can be seen that in the form of a stake-JQ tsa there are only one number of tools stores 2 in order to form a sector 8 free from stores that can have an angle (5 60-90Л. Column G has supports 9, a base 10, which can be made in the form of a pedestal or embedded in the machine bed.The column 1 can be connected to the base 10 with a positive fit, for example by welding or a pin joint, or by force closure by means of a clip. In the latter case, the advantage is a society of 25-step radial adjustment of the entire tool storage.
    From FIG. 3, it can be seen that the column 1 is a drum-shaped rotor support 11 composed of upper and 30 of lower circular guides 12, 13 connected by a drum 14 coaxial with them, while the rotor 11 is mounted on column 1 with bearings 15 and 16 The rotor 11 is driven in rotation by a motor drive 17, for example, a hydraulic motor 18 and a gear transmission 19, and the gear gear 20 is engaged with the gear wheel 21 aligned coaxially with respect to the Q axis of the column 3 and fixed on the lower guide 13. clockwise
    an arrow and against, at step or stepless regulation. The tool magazine 2 is supported by rolling bearings 22, 23, including the rollers 24, on the guide rails 12, 13 with movement.

    The gripping device 25 consists mainly of two opposite lifting blocks 26, 27, for example, pneumatic or hydraulic cylinders fixedly supported on the bed 28. The lifting blocks 26, 27 have gripping elements 29, 30 at their ends, with which the tool magazine 2 is gripped, centered and offered to the tool changer

    at the proper height. With the help of lifting units 26, 27, several lifting positions can be realized.
    At the same time, as the gripping device 25 is fixedly mounted on the frame 28 (Fig. 4), the additional gripping device 31. is mounted on the rotor 11. With it, it can be used to detect and fix a specific tool magazine 2. FIG. 4 shows two gripping devices 31, but this is the same device, which is depicted in two different positions (see arrows 32, 33). The additional gripping device 31 consists of the support rod 34, as well as the upper and lower gripping forks 35, 36 and is lifted by a lifting mechanism 37 located on the control ring 38 mounted on the rotor 11 in the direction of the arrow 33. In this position the second gripping the devices 31 gripping forks 35, 36 fix the bearings 22, 23 of the selected tool magazine 2, so that when the rotor 11 rotates, this magazine rotates with it.
    According to FIG. The 4 circular structures of the tool storage and the 8V sector, which is arbitrarily disposed from the shops, allow choosing the place of tool grip on the entire circumference of the storage ring. The tool can be fed to the loading and unloading station 39 here. With the help of the feed lever 40. With the storage device to be located, the feeding lever 40 can be rejected and the tool can be changed directly with the loading and unloading station 39. The next feeding lever 41 serves for , to carry out the change of a separate instrument manually at an auxiliary time.
    Drive tools works as follows (Fig. 6).
    In the initial position, the rotor 11 is equipped with a loading and unloading station 39 with 2 tool shops. The latter carry the identification code that is entered into the machine control.
    The gripping device 25 fixes the tool magazine with code 101 (Fig. 6). The machine program calls up a tool shop, for example, with
    516
    code 115. The rotor drive with an additional gripper 31 receives a command impulse to turn in a clockwise direction. A tool magazine with code 101 is fixed on the outside and all other tool stores are smeared on this store. Additional gripper device 31 is now moving along with the rotor from the store, with code 101 to the store with code 115. While moving, indicator 42 counts the stores and reports this to management (here it counts the difference of codes from 122 to 115). In the penultimate store (here code 116). switches from rapid traverse to positioning speed. Upon reaching the store with code 115, the auxiliary gripper 31 is precisely stopped and positioned. At the expense of an additional gripping device 31, a magazine with code 115 is connected to the rotor. After the release of the magazine with code 101 by removing the gripper 25, the rotor is accelerated. Now all stores that are in the direction of rotation in front of the code 116 store are forcibly co-accelerated.
    Shops with codes 116-122 are accelerated only by friction. This is preferred since, on average, the rotational drive does not have to develop the entire maximum starting torque. In the meantime, a more rapidly accelerated store with code 101 overtakes a store with code 129. A shop-free sector has now emerged between a store with codes 115 and 116. A store with code 115 is approaching the point of transfer using a pick-up device 25. The drive speed decreases up positioning speed. All stores, except the store with code 115, due to their inertia, maintain speed (respectively, slow down due to friction) and form (independently) in the desired location, as in the initial position5, shop-free sector 8 for a loading and unloading device for tools .
    When the gear position is reached: .. with a magazine with a code 115, lifting blocks 26, 27 of the gripping device 25 raise the magazine to the desired height. Now using boot times 82786
    the load device tools can be taken from different positions of the magazine, and the working cycle is repeated again.
    Fig. 7 shows a section through the tool magazine 2 with the tool 5. The tool is held in the tool holder 43, having an adaptation 44 for clamping the tool shank, which includes a loading and unloading ring 45 with a gripping groove 46 and a tool cone. 47
    5 The latter has a retaining pin 48 with a neck 49, which is bounded by an end flange 50 and into which the fixing pin 53, which is guided in the retaining ring 52, enters with a spring 51 and which cones 47 is directed with springing with the help of 2 tools retained in the magazine of an elastic ring 54, a circle of the ≤5 solid section and positioning- with a stubborn pin. Due to this arrangement, the tool holder 43 is held in the tool magazine 2 with a positive fit,
    0, however, after overcoming the force of the spring 51, it can be gripped by the loading and loading ring 45 and removed.
    If in certain machines a gripping device 25, made on
    the accumulator in the form of a lifting feeder is insufficient, then the feeding lever can be equipped with a lifting or turning mechanism. The rotary mechanism allows (FIG. 8) rotation of the tool magazine 2 around the axis of rotation S,
