    The invention relates to a machine tool industry, in particular to the processing of workpieces by means of a replaceable tool .5
    A metal-cutting machine is known, which contains at least one machining position with a clamping device for workpieces, tools rotatable by means of JQ drive means and mounted in toolholders moved sequentially to and from the machining position along a closed guideway 1 3. AC
    However, the known machine is ineffective in processing the same type of parts of different sizes, since it requires considerable time for its retooling and has limited application.
    The purpose of the invention is to eliminate these disadvantages.
    The goal is achieved by the fact that each tool holder is equipped with a half-coupling and is mounted slidably along a closed guide and the tool drive means is made in the form of a carriage mounted to move along 30
    the machine base in the transverse direction with respect to the closed guide and carrier drive of the rotating tools with the leading coupling half, interacting with the coupling half of the tool holder.
    Figure 1 shows the proposed machine, showing the configuration of the guide and the location of one or several processing positions, top view, figure 2 - the part of the machine near the processing position, on which the output and transport bar and interaction are shown: the mechanisms with them, side view, fig.Z - section aa in figure 2; on. Fig.4 - section bb in Fig.2; FIG. 5 is a sectional view B-B in FIG. 2, FIG. 6, section G-D in FIG. 2) in FIG. 7 — a part of the machining position and means for orienting and fixing the tool head, a means for supporting the drive motor of the tool head, a support for the workpiece and a rotary table; FIG. type of drive caliper billet; in Fig. 9, the means for driving the rotary table / in Fig. 10, the support of the rails and chains and the lateral directions to the tool holos.
    on -JJHr.ll - chain drive, plan view; Fig. 12 shows the construction of the chain; Fig. 1 shows the guide of the tool head, the support rails and the means for mounting and fastening; Fig. 14 is a typical device for fastening the workpiece; Fig. 15 shows a multi-hole drilling head; FIG. 16 shows a machine in which the means for mounting and fixing the tool head at the machining position is made in the form of a cam, is fixed to it on the drive of the tool head and interacting with it; FIG. 17 is a plan view of the mechanism shown in FIG. 16, FIG. 18 is a section DD-D in FIG. sixteen.
    The metal cutting machine 1 contains an endless guide 2 and a processing position 3 located at one and two points of the guide 2. Secondary processing positions 4 and 5 can be located on the guide, depending on the production needs.
    Guide 2 is shown elongated, and its trajectory has straight sections connected by rounded sections. The set of tool heads is installed on the guide. 6 The movement of the tool 6 heads is not synchronized, i.e. A certain head or heads can be stopped at some positions, while other heads move along a guide until they are pressed into a stationary head, or they are not stopped otherwise, or are fixed as described below. All g5 tool heads are arranged in a specific sequence and all the time are on the guide. 2, on which there is a tool change zone, to which a selectively activated stop 7 is mounted, allowing the service technician to replace a blunt tool or, if necessary, to make a changeover. The ability to change tools during machining at position 3 increases productivity. Since guide 2 is located at a convenient level; the adjuster does not have to climb the ladder when changing tools.
    In Figure 1, for example, sixteen tool heads b are shown moving counterclockwise. These can be multi-spindle drilling heads, thread-cutting heads, boring or milling heads, and each head has a bottom plate 8 (FIG. 10). Guide 2 consists of a pair of racks 9 and 10 connected by a spacer 11. Passing between racks 9 and 10 T chains 12 and 13 (Fig. 13) Each chain of Fig. 12) consists of plates 14 and 15 connected by vertical axes 16, carrying rollers 17
    on the washers 18. The upper ends of the axles 16 are fixed in the sickle plates 19 (Fig. 11), whose external parts rest on the supports 9 and 10 of the guide 2. The lower plates 8 rest on the plates 20, creating a frictional movable connection of tool heads with chains.
    For the drive of chains 12 and 13 there are sprockets 21 and 22 driven by electric motors 23 by means of belts and gears (not indicated
    Fig. I shows the installation of the guide 2 to the floor 24. The base 25 with equalizers 26 is equipped with racks 27 and 28 and ribs 29,. On the upper platforms 30 there are racks 9 and 10, as well as guides 31 and 32 tool heads.
    FIG. 7 shows part of the processing position 3, in particular the means for driving the tool heads and the means for mounting and fastening them. The tool head drive means 33 has a base 34, on which the slide 35 is supported, which is moved along the reversing guide 2. On the slide 35, an engine 36 is mounted, having a shaft 37 with a coupling half 38, connected to the drive coupling half 39 of the tool head 6. The coupling can be performed pneumatically, then at the opposite end of the shaft
    37, the pneumatic brake 40 and the rotating element 41 for supplying cooling and compressed air are set.
    The toolhead drive means 6 is moved from a working position, shown in solid lines in Fig. 7, in which the coupling half
    38 is connected with the coupling half 39 of the stop and fixed head, to the non-working position shown by the dotted line. For this movement, a screw 42 is used, rotated by a drive 43 mounted on the base 34.
    The tool for mounting and fixing tool heads at the machining position has, for the outer and inner KpiaeB of each of the lower plates, a pair of rails 44 and 45 (Fig. 13). The upper surfaces of these rails are located slightly above the level of the sickle-shaped moving plates 19. For this, at the ends of the rails 44 and 45 are protrusions 46 and 47 (Fig. 2). Between the rails 44 and 45 and their chains 12 and 13 there are two pairs of mounting shafts 48 and 49. Outside the rails there are two pairs of clamps of tool heads 50 and b1. The clamps are the same as the rails 44 and 45 are located on the protrusions 52 and 53. With the help of the working cylinder 54 installation and fastening clamps and pins are moved vertically (Fig.2). The sequence of work is as follows: first
    the pins 48, 49 rise and enter the mounting holes 55 of the bottom plate 8, then the clamps 50 and 51 lower, rigidly fastening the bottom plate to the rails 44 and 45. When releasing the toolhead, the clamps first rise, and then the pins go down.
    Typically, each of the heads is installed and secured to the processing position after stopping. However, if 3 any moment of machining a workpiece enters the working position, the head is not required for processing this workpiece, it can be passed further without installation and fastening. This is done, for example, by reacting the installation and fastening means to the designation printed on the head. For example, each head may carry a specific set of symbols, such as a signal switch 56 (FIG. 1), acting on an identification means, made in the form of a sensing element 57 mounted on a processing position. Such an element will send a signal to a computer or other control device 58, which will compare this signal with the part's processing program at the processing position. If the head is to be used, a signal will be transmitted to the tsilinda 54 for installation and -mounting. Otherwise, the stopped head will not be installed and fixed, but will be moved from the position of processing and its head will be replaced by another.
    The means for delaying each successively moving head in a position before the processing position and for moving the head thus held in the processing position (FIGURE 2-6) contains a displacement rod 59 and an output rod 60 extending parallel to the guide 2 next to the processing position 3 Moving rod 59 rests on rollers with a concave surface 61 and moves reciprocatingly and rotates around its own axis. The stem 59 has a pair of dogs 62 and 63 spaced apart from each other, interacting respectively with the front and rear end of the bottom plate 8 provided for this with grooves 64 and 65.
    The double-acting hydraulic cylinder 66 is connected to the moving rod 59 and moves it from the retracted position, in which the dogs 62 and 63 engage the tool head 6 directly in front of the machining position, to the forward position in which this head is moved to the machining position. Dog 62 is somewhat longer than dog 63 and, when the head is moved forward, interacts with shoulder 67 of head 6 at the machining position, wadding head with ezlay position.
    The outlet bar 60 has a pair of angled dogs 68 and 69 disposed at an angle (Figs. 4 and 5). The rod 60 rotates around its own axis on the protrusions 70, while the arrangement of the dogs is such that the coffer 68 holds the head located on the two heads to the working position, and the dog 69 holds the head directly in front of this position.
    Hydraulically: The 1st cylinder 71 double action has an extended rod 72
    5 with slots 73 and 74 (Fig. 6), in which the protrusions 75 and 76, respectively, of rods 59 and 60, are included. When the bar 72 is moved forward, the dog 69 moves to the holding position and the dog 68 moves to the release position.
    0 The boom rotates to lower their dogs. The reverse movement of the rod 72 creates the opposite effect.
    The operation of the holding means,;, re 5 of moving and cleaning heads is described with reference to Fig. 2, where the tool head is shown, one of which is at the processing position, the second before it, and the third 0 before the second head. In the position when the second head 6 is clamped between the dogs 62 and 63, and the dog 6C holds the third head in the position shown in the drawing, cylinder 54
    5 moves forward, releasing the first head and retracting the dowel pins from under it. The displacement cylinder 66 actuates, pushing out the first head 6 from the position o6pa6oTKf and displacing the second head 6 in its place. If the second head is necessary for operation, which is determined by the signal from the switches 56 to the control device 58, the cylinder 54 will move backwards, installing and clamping the second
    5 head 6 in the processing position. The cylinder 71 of rotation of the rods will move forward, freeing the second head 6 from the movement dogs and freeing the third head. The transport chains 12 and 13. Move the third head until it is stopped by the output pawl 69 at the position of the second head 6. The movement cylinder 66 moves back,
    5 returning the moving rod to its original position, and then the cylinder 71 will move away, causing the moving dogs to interact with the third head. Further, the whole operation
    0 to, repeats.
    The support of the workpiece (Figs. 7-9) includes a base 77, located on the side of the guide 2 on the opposite side of the device for driving the tool heads, and a slide 78,
    five
    Moving to the head attached to and from the machining position. Other types of supports can be used, for example with cross feed. The slide 78 moves along the guides 79, extending over the base 77. The feed and lateral movement 80 is mounted on the outer side of the base 77 and connected to the slide 78 by means of a stop unit 81, a screw 82 and a ball nut 83.
    A rotary table 84 mounted on bearings 85 is mounted on rails 78. The table 84 is rotated by an electric motor 86, through a gearbox 87 and a gear wheel 88 engaged with a ring gear 89 made in the table 84. Under the table 84 there is one or more stops 90 that interact with the stopping mechanism 91.
    A typical fastener-clamping device 92 mounted on a turntable 84 has racks 93 and upper members 94 carrying clamping screws 95 with clamps 96 cooperating with the workpiece 92, shown with dotted lines. This device also has mounting bosses 97 and mounting pins 98 for fixing the workpiece. One or several limit switches 99 interacting with the workpiece as an identification can be installed on this device. These switches can be connected to the control device 58.
    A conventional multi-spindle tool head B (Fig. 15) used, for example, for drilling, has a drive shaft 100 rotating the gears 101 of the spindles 102. During the drilling operation, the workpiece 92 is fed in the direction of the spindle m.
    In addition to the drilling operation, the machine can be used for threading, boring, milling, etc. for which the machine is equipped with the corresponding heads 6.
    The sequence of the processing cycle of the workpiece 92 is as follows. When the workpiece is clamped in a device for clamping it, the operator, who is, for example, at processing position 103, turns on a selector switch indicating which type of workpiece is being processed, while the control device 58 selects or sets the correct program. Alternatively, switch 99 may serve to designate a blank to a control device. If the tool head 6 (Fig. 1) is in the machining position, the sensor
    57 sends control device
    A signal indicates that the head b is in the working position. The control device will check if this head is necessary for the first operation and, if so, give a signal to the cylinder 54 to install and clamp the head and a signal to the actuator 43 to approach the head drive device to this head and turn on the drive motor 36. The control device will also give a signal re-table 84 on the correct installation of the workpiece. For example, if the workpiece has two surfaces to be machined, the table will rotate so that the first of them face the tool head. There is a means of signaling the control device that the rotary table is correctly positioned. The control device then signals the actuator 80 to quickly bring the slide 78 to a certain position, indicated by a limit switch from which the working feed begins. The signal to end processing of the sled 78 is quickly retracted, freeing the head.
    When the retraction of the slide 78 ends and the engine 36 stops, a signal is received to release the head and retraction of the dowel pins 48 and 49. At a signal indicating the end of this operation, the control device causes the displacement rod 59 to remove the head b from the machining position and set to its place is the second head 6, which stops when the piston of the cylinder 66 reaches its extreme position. Meanwhile, the third head 6 takes the place of the second head.
    The control unit identifies this head. If it turns out that this head is needed for further processing, the installation, clamping, fast approaching, working feed and tool head operations are performed again. After the machining of one surface of the workpiece is completed, the next head arriving at the processing position will send a signal to the control device to turn on the DRIVE 86 of the turntable 84. The table 84 will turn the workpiece to the other side, which will be processed by the next group of heads proceed as described. If any head arriving at the machining position is marked as unnecessary in this work program, it will be removed and replaced with the next one.
    Figures 16-18 illustrate another embodiment of the device for mounting and attaching tool heads using cam means for driving the head, interacting with the head when the drive and the head are interconnected. On the guide there are two endless chains 104 and 105 similar in construction to those described. They have plates 106 that provide a movable nt-iodine connection to the bottom surfaces 107 of the lower plates 108 of the tool heads 6. A pair of rails 109 and 110 are mounted on the machining position. The mounting and fastening device contains a cam wedge 111 mounted on the slide 112, the engine 113 drive tool head 6. This wedge is tilted down and interacts with the cam 114 mounted on the tool head b. In this interaction, the wedge tends to push the head down and to the right (Fig. 16J with the help of the wedge surface 115 and against the direction of movement of the chain 1Fig.17) with the help of the wedge surface 116. Before the wedge 111 rests on the cam 114, the head 6 takes the position shown dashed lines in FIG. When the slide 112 moves forward, the clutch il7 is connected to the drive shaft of the head, the head is shifted to the right, taking the position shown by the solid lines in FIG. 16 Opposite the sled 112, there are a pair of stationary mounting surfaces 118 at the machining position. These surfaces are inclined downwards and interact with the additional surfaces 119 of the tool head 6, restricting its movement to the right. At the same time, the surfaces 115, 118 press the head against the rails 109 and 11. The installation of the head 6 along the guide is carried out using the lib wedge surface interacting with the additional surface 120 of the cam 114, while the wedge surface 121 interacts with the additional cam surface 122. To return the head to its normal position when the slide 112 is removed, there is a rail 123 located on the side of the guide against the slide 112 and displaced to the slide by a spring 124. The rail 123 is located below the surfaces 118 and the bottom plate 108 interacts with it when position of installation and fastening, compressing the spring 124. When returning the slide 112, the spring 124 pushes the rail 123 outward, returning the head to the position shown by the dotted line in FIG. 16. The device for mounting and fastening the tool heads of Figs. 1b1-18 interacts with the other components of the machine, similarly to the pins and clips of the previous type of embodiment. Similarly, moving and output rods are used to move successive tool heads to the machining position, with the difference that the installation and fastening are made in accordance with the supply of the actuator drive device and the release at the same time as the drive retraction. A device for holding the toolhead in front of and at the processing position (Figures 16-18) can be used instead of the displacement and output rods and the mechanisms described with them. It contains a stopper 125 mounted for lateral movement in front of the treatment position and displaced by the spring 126 to a position in which the approaching head 6 is held directly in front of the processing position. At the machining position, there is another stopper 12 / for stopping the head 6. On the sled 112, a retractable locking paw 129 is mounted, cooperating with an element 129 of the stopper 125, to retract this stopper under the action of the spring 126 when the carriage 11 retracts. coordinated with the movement of the stopper 125 in order to ensure the release of the tool head and its movement to the machining position, at which, through the interaction of the planes 130 and 131, the head located at the machining position shifts from it. In order to increase the reliability of the installation and the fastening of the head to the position of processing and disconnection with the tool driving means of the tool head after the installation and fastening are completed, the circuits 104 and 105 can be installed in the withdrawable carriage 132 of the chain support at the processing position. This trolley is mounted on a hinge from the side of the trolley on the side remote from the sled 112 and has a cam surface 134 near the sled that interacts with an additional wedge 135 on the sled 112. In the normal position the trolley 132 is displaced upwards by the spring 136, but when the wedge 135 acts to cam 134, it will be retracted downward, ensuring reliable separation of the chain plates 106 and the bottom plate 108.
