    The invention relates to a machine tool industry, in particular to tool holders mounted in an aperture of a tool holder by means of grippers for their automatic change.
    The aim of the invention is to expand technological capabilities by ensuring the change of tool holders with different configurations of heads with the help of ordinary grippers with identical gripping surfaces with medium sized sheds.
    Figure 1 shows a part of the automatic lathe with tool holders, top view; figure 2 - section aa in figure 1; on fig.Z - a part of the current of the automatic machine with a different arrangement of tool holders, top view; figure 4 - one of the tool holders according fig.Z on an enlarged scale; on Lig.5 - tool holder, side view; in FIG. 6, the same, in the position established in the hole of the tool slide, longitudinal section; FIG. 7 is a view B of FIG. 5.
    Fig. 1 shows an instrumental support 1, made in the form of a revolving head of a turning automatic machine and having the possibility of rotation around a horizontal axis 2. Along the perimeter of the instrumental support 1, several tool holders 3 are fixed at the same angular intervals, equipped (equipped with tools. Two tools 4 are shown for internal machining, namely boring bar and twist drill, radially located with respect to axis 2. The following, located on the tool holder 1, are tool holders 3, of which The din can be seen in Fig. 2, can be equipped with tools 5 for external machining, for example, turning cutters. The tool holders are matched with the type of tools 4 or 5 that need to be fixed in them, and have correspondingly different outer shapes and sizes. 2 above the tool holder 3, which has a generally square outer contour, shows a tool holder with a round-shaped contour,
    Alternatively, the tool caliper 1 in FIG. 3 is shown in FIG. 1, the tool caliper 1 is shown, made in the form of a four-sided turret head

    the horizontal faceplate pivotally rotates around a perpendicular axis 2. The four sides of the tool holder 1 are respectively occupied by one or two tool holders 3, which are respectively equipped with one tool 4 for internal machining or one tool 5 for external machining,
    To replace the tool holders 3 together with the tools 4 and 5 belonging to them in the tool holder 1, according to FIGS. 1 and 2, at least one gripper 6 is provided, having two fingers 7 and 8 that are movable relative to each other, namely a finger 7 with a curved internal edge and finger 8 with a straight inner edge. Corresponding gripping is also intended.
    for the tool holder 1 in FIG. 3 (not shown). The gripper 6, according to FIGS. 1 and 2, respectively, can be brought into contact with the toolholder 3, which occupies an operating position with respect to the clamping cartridge 9, which can be rotated around the axis 10 of the working shaft. Alternatively, the gripper 6 can appropriately replace the tool holder 3, which occupies a position offset by angle with the chuck 9, for example, 90.
    Each tool holder 3 has a head 1I with tool locking means 4 or 5. Referring to FIG. 4-7, the locking means consist of a fixing groove 12, a clamping plate 13 and a pair of clamping screws J4 for clamping the tool 5 for external machining as a turning tool. On the distal side of the tool carrier head 11 far from the fixing groove 12, there is a flat bearing surface 15,
    In the middle of the support surface 15 and perpendicular to it, the shank 16, mainly of a cylindrical shape, which can have a pin and teeth 17 on its upper side, is located away from the head P of the toolholder (Fig. 4-7). Shank 16. the toolholder enters the receiving opening 18 of the tool carrier 1. In the tool holder 1, the lock 19 is displaced transversely to the receiving opening 8. Internal to the
    to the receiving opening 18, the end face of the constipation 19 is also provided with teeth designed to interact with the teeth 17 of the shank. The clamping device 19 with the help of a clamping device not shown in the drawing, of a conventional construction, exerts a force action radial with respect to the receiving opening 18, which through the teeth 17 is converted into an axial force, which engages the toolholder shank 16 into the receiving opening 18,
    According to figure 1-7 between the supporting surface 15 and the flat surface 20 is a gripping plate 21.
    The grip plate 21 is a relatively thin plate of hardened steel. Its thickness d in the illustrated example is twice as large as the pitch t of the teeth 1. The teeth 17 extend along a sufficiently large part of the length of the toolholder shank 16, so that the gripping plate 21 located between the support surface 15 and the flat surface 20 cannot prevent the constipation 18 in that so that it interacts properly with the teeth 17 in the same way as in the case of the toolholder without a pick-up plate 2J.
    The gripping plate 21 has a central hole 22 and is fitted on the tool holder shank 16 in a tight fit, so that it is precisely centered with respect to it and to the entire tool holder 3. On the upper side of the gripping plate 21, according to FIG. 4-7, two gripping surfaces 23 and 24 for grip 6 formed with a curved inner edge of the finger 7. In accordance with the bend of the inner edge of the finger 7, the gripping surface 23 is inclined to the horizontal central axis of the tool holder 3 by 45 (FIG. 7), while gripping to the surface 24 is tilted on to the DA in prrtivopolozhnom direction. On the underside of the gripping plate 21 (Figures 4-7), a third gripping surface 25 is made, extending parallel to the horizontal central axis of the tool holder 3. This third gripping surface 25 is intended for a gripper 6 with a right inner edge of the gripper 6,
    1 o
     JiixnaTHaH plate 21 has its HdKpyi b; e of the central hole 22 are four respectively offset from each other with an angular spacing of 90 mounting holes 26, into which the screws with a countersunk head 27 are passed. The head 11 of the tool holder has correspondingly spaced screw holes with screws countersunk head 27, Thus, the gripping plate 21 is fixed on the tool holder 3 rigidly and with precise centering. However, after loosening the countersunk head screws 27, it can be rotated through an angle of 90 or a multiple of an angle and re-secured if this is more expedient considering the interaction with the gripper 6,
    Each of the gripping surfaces 23-25 may be inclined to the longitudinal axis of the tool holder shank 1G in such a way that, together with the supporting surface 15, it forms a view of a groove of a V-shaped cross section,
    According to FIG. 7, the gripping plate 21 has an eccentrically located opening 28, which normally interacts with a centering pin (not shown) fixed to the tool holder 3. The centering pin is hollow and attached to the line.
    a coolant which, through the opening 28, is connected to the coolant channels in the head 11 of the toolholder,
    To secure the tool holder 3
    in the tool holder, it is gripped by the corresponding gripping surfaces of the plate 21, transported and installed in the receiving hole 18 of the tool holder.
    caliper, followed by fixing by known means, in particular with the help of the constipation 19 located in the caliper with teeth on the end, interacting with the teeth 17 of the shank I 6,
    The presence of a gripping plate 21 with gripping surfaces located on it provides the possibility of transporting and installing tool holders in the support with heads of various configurations using grips with the same gripping surfaces with the shed of medium ratmers.
