    The three-spindle machine uses all three spindle axes. The rack 1 is subspecific in the directions X and Z, and the slides moving along the rack 1 in the direction Y, with three 2 spindles 3 mounted on the carrier, driven by engine 4, are arranged symmetrically on the rack. The movement of the spindles in all three coordinate directions is used not only for machining, but also for most of the movements required for changing the tool. The tool cassette 5 (Fig. 2) serves to directly store several tools. The cassette 5 is made flat, in the form of a strip with several fitting grooves - sockets 6 dp of tools, while in the cross section the socket has the shape of an open groove and as a saddle enters between two conical disks of the tool. In order to increase the capacity of the cassette in the gry sockets 6 v. The cassette 5 is larger than the number of spindles, for example, six slots 6 are formed in the cassette 5 (figure 2). The distance between the sockets 6 in this case is half the distance between the main spindles, this is in the cassette there is a group of tools in an amount sufficient to equip the spindles twice. When changing tools, the machine takes out every second tool and returns used tools to every second nest 6.suhar, when the clamshell hand 11

    more tools. In cassettes, the number of sockets 6 n is a multiple of the number of spindles, and n is an integer. In the cassettes, the orientation of the tools takes place by means of the positioning crumbs 7. In addition, two employees are attached to the ends of the cassette to grip the cassette of the side crumbs 8, to which the clamshell fixes the cassette from the magazine in one or the other direction. For example, behind the right cracker, the cassette in the automatic tool change cycle can be stretched into the working space of the spindles of the base machine (to the right. Figure 5) and, using the left cracker, in the opposite direction for manual loading of the magazine. rotating around a horizontal axis 9, located perpendicular to the spindle of the base machine, a ban bar with a red flow in the shape of a regular polygon (figure 3, hexagon). One edge is attached to the edges of each side of the polygon in the form of tires 10, between which the corresponding cassette 5 is held, with the tools clamped in it protruding into the drum shop. With the aid of fixed tires on the reel of the tire shop 10, the tool cassette is guided. The upper tire also serves as a guide and also for locking cassette slots from above when it is placed in the drum magazine. This simply and reliably prevents tadeia of instruments when turning the drum.

    more tools. In cassettes, the number of sockets is 6 n multiple of the number of spindles, while n is an integer. In the cassettes, the orientation of the tools takes place by means of the positioning crumbs 7. In addition, two employees are attached to the ends of the cassette to grip the cassette of the side crumbs 8, to which the clamshell device pulls the cassette from the magazine in one direction or the other. For example, for the right cracker, the cassette in the automatic tool change cycle can be pulled into the working space of the spindles of the base machine (to the right. Figure 5) and using the left cracker in the opposite direction for manual loading of the magazine. The store can be made as rotating around horizontal axis 9, located perpendicular to the spindle of the base machine, a red-flow drum in the form of a regular polygon (figure 3, hexagon). One edge is attached to the edges of each side of the polygon in the form of tires 10, between which the corresponding cassette 5 is held, with the tools clamped in it protruding into the drum shop. With the aid of fixed tires on the reel of the tire shop 10, the tool cassette is guided. The upper tire also serves as a guide and also for locking cassette slots from above when it is placed in the drum magazine. This simply and reliably prevents tadeia of instruments when turning the drum.
    Ethanok works as follows.
    The cassette 5 with the grab hand 11 of the grab attachment is removed from the magazine by gripping the biscuit 8 (figure 4). The clamshell hand 11 has a horizontally directed and-shaped exciting rusk, and the shoulders of which cover the rusk 8 in front and behind. Due to this, the rotation of the cassette 5 rusk 8 comes between the and-shoulders of the exciting When a gripper is 11
    the direction of the cassette 5 of the fastening rusk 12 spring-loaded J3 ha of the end of the cassette 5 so that it enters the notch of the fastening rusk 12. This prevents the cassette 5 from moving in any direction relative to the clamshell arm 11. In which the rear end of the cassette is still engaged with the grooves of the tires 10, both ends of the cassette are fastened.
    When the clamshell hand 11 pushes the cassette 5 into the magazine, the fastening rusk 12 (in the last phase of the movement) runs onto the wall 14 of the magazine as the hand moves further 11 to the left end of the cassette 5 slides out of the fastening rusk 12 and unfastens.
    The cassette 5 can be moved with a grabber from a rotating around axis 9 using the mechanism 15 for turning the drum magazine into the working space of the machine (Fig. 5). With an automatic tool change, it is sufficient if the grabber performs a single movement, since other necessary movements — inserting or removing tools into or from the cassette, positioning the spindles along the tools, running or releasing them — are simultaneously executed by the machine itself with three tools with help coordinate movements. The clamshell adjustment consists of a horizontal displacement parallel to the axis 9 of rotation of the drum magazine of the drive rod, at both ends of which a perpendicularly protrudes along one clamshell arm 11 having pads 16 (figure 4).
    When the Turning Mechanism 15 only rotates the drum magazine in half division, in this position the clutch between the cracker 8 and the clamshell 16 is stopped. The grab hand can move to the right without taking the cassettes with it. After the drum is turned back to half a division, with the claw hand shifted to the right, a connection occurs between the left claw block 16 of the claw hand 11 and the left cracker 8 of the cassette. With the claw hand 11 when moving it to the left, the cassette is pulled out and access becomes0.
    For manual loading or tool changing.
    The workpiece is fastened on prismatic pallets made with a square rectangular section (Fig. 6) On each plane of the prismatic pallet three or n X 3 workpieces with small dimensions are held (n is an integer). Thus, on both prismatic pallets, at least 2 x 4d3 identical blanks can be fixed. One of the prismatic pallets, for example prismatic
    5 of the pallet 17 is in the working space of the base machine, while the other prismatic pallet 18 is in the mounting position at the place of the manual clamping of the blanks.
    0 The prismatic pallets are freely captured or axially guided into the rotates around the axis 19 of the rotatable cages 20 and 21. The prismatic pallets can in cages several
    5 move in the longitudinal direction. This movement to the right is limited by the emphasis of the hangers 22 fixed on the prismatic pallet and to the left by means of closing the discs fitted with the front teeth of the leading rims 23 and 24.
    The conical holes 25 of the ring hangers 22 include spring pins 26 that are prepositioning, which prevent the prismatic pallets from turning when the spaced pallets and end caps of the leading rims 23 and 24 do not fit into each other.
    0 The prismatic pallet 17, which is located in the working space, is fastened to the pillars 27, 28 by means of a clamp - a hydraulic cylinder 29, which by means of
    5 the tailstock 30 moved by it shifts the prismatic pallet 17 to the left. The back of the headstock 30 consequently presses the Veduac crown 24 with a large force to the drive rim 23 fixed on the rack 27. The rotational movement of the prismatic pallet around its own axis occurs with the help of a cylinder 29 - which does not have a tailstock 30 back, the cylinder 31 shifts the prismatic pallet 17 from the other end through the drive block 32 to the right, while the leading fingers 33 of the leading block enter into the end holes 34

    prismatic pallet 17, so that it can be rotated when the drive rotates. This rotation Dfig, 6 can occur with the help of a pivotally mounted hydraulic cylinder 35 and a lever 36 or, for example, with the help of a direct current motor through a gear transmission, etc. The pallet is positioned and secured by moving the tailstock 30 to the left then, when the cylinder 31 t does not have the drive block 32 in its left end position, which can be rotated to its main dividing position.

    Fixing the pallet is also possible on the unloading pillar 37. If all the cylinders 29, 31, 38 and 39 are in the retracted position, the prismatic pallets replace each other by rotating the horizontal shaft 180 °: in the pallet mounting position. - day and in the workspace, and being in the workspace - in the installation position.
    The rotation and positioning of the E1; it is in the installation position of the prismatic pallet 18 is carried out in a similar way, but with the only difference that the fixation takes place not on the uprights 27 and 28, but on the offloading posts 37 and 40, and these stands 37 and 40 are independent and connected only through the base console (Fig.7),
    The working space is separated from the mounting space by means of the plate 41, which is made of a transparent material. This plate 43 rotates when changing; pallets with chambers around axis 19 and serves mainly to protect the installation space from. shavings and cooling fluid.
    The prismatic pallet 17.turns in cages 20 and 21, in which the pallet is shifted to the left fixed by means of a hydraulic cylinder 29 on a guide rim 23 fitted with end teeth 23. Blowing for the longitudinal direction of the cylindrical ends of the pallets, Kielce rows of balls 42 and 43 rolls along the cylindrical ends of the pallets and fall into the V-shaped slots 44 and 45 of the pallets, which excludes

    The automatic clamping of prismatic pallets is applicable not only in a bicameral system, but can also be extended to multi-pallet systems with a change of pallets. The prismatic pallets 18, 46 and 47 (Fig. 9), instead of pivoting clips, are freely guided in small carts 48 to 51 in the same manner as described. Trolleys using a hydraulic cylinder 52 with a swivel stand. La 53 can be shifted by linear movement into the working space. When the hydraulic cylinder 52 moves back, it doesn’t have a trolley, 48 to an annular rotary table-53, which can rotate trolleys with airplanes, thus other loaded pallets can be brought in front of the working space. . During rotation, the radial position of the carriages is determined by the rollers and the fixed directional guide fixed on each carriage. ring 54, which enters between both rollers, while its small segment can be radially moved by means of a hydraulic cylinder 52. With the help of segment 55, the cylinder shifts either from carts or pallets into the working space. The plate 56 fixed on the back side of the cart closes the working space. The cart remains during processing in the work area.
    Other three pallets located outside the working space can be positioned and removed in any position due to this machine, and can be serviced by several devices with high productivity.
    Sometimes it is necessary that the workpieces are placed on pallets not near the machine, but somewhere else. In this case, the pallets should be easily removable from the annular turntable. At both ends, the pallets are made of prismatic and cylindrical surfaces 57 and 58 (Fig. 10), the latter being supported through ball bearings on the pallet carrier trolley 59. These ball bearings 60 also facilitate the axial movement of the pallets (offset to the end teeth of the leading
