Description

1 The invention relates to a machine tool industry, in particular to a multi-purpose drilling and milling-precision group of machines equipped with devices for automatic tool and header change and multi-station drives. The purpose of the invention is to increase productivity by carrying out long-term work of the machine without the human being, and also by storing and exchanging replaceable devices 1 for a multi-nozzle program of the machine. FIG. 1 shows a CNC multi-purpose machine; Fig.2 is a view of A in Fig.1. The machine consists of a base 1, which is installed column 2 with guides 3 for carriage 4, carrying a rotary table 5 with guides 6 for satellite devices 7. Conveyor 8 has two branches with guides 9, on which are in contact with each other -satellites 7. A plate 10 adjacent to the end of the conveyor 8 is equipped with a movable slide 11 with a post 12, on the horizontal axis of which a double-arm 13 is pivotally fixed, at the ends oppositely directed platforms 14 and 15 with guides 16 for fixtures 7 travelers parallel guide 6 section 5 in its original position. A two-position trolley 17 with cross guides 18 and 19 is located at the opposite end of the conveyor 8. The upper guides 18 of the trolley are parallel to the conveyor guide. On the cross table 20 there is an instrumental headstock 21 with a horizontal spindle. The hydraulic cylinders 22, 23 and 24 with tack-driven rods provide the movements of the satellite devices 7 in the machine cycle. The machine works as follows. Before starting work, the satellites 7 with blanks are mounted closely on both branches of the conveyor 8 and on the platforms 14 and 15 of the rotary lever 13. Then, at command, the satellite 7 that was on the top platform 15 pushes 52 SI with a special drive (not shown) on the guides 6 of the turntable 5, which is in the initial position, when its guides coincide with the guides of the lever 13. A work-processing cycle is activated, during which the carriage 4 with the table and the instrumental head 21 iruyuts relative to each other along axes X, Y and Z, the multilateral machining of the workpiece is performed. At this time, the slide 11, together with the two-arm lever 13, is moved to the left, freeing the working area. After finishing the first part, the carriage with a table rises up and at the same time the slide 11 with the lever approaches the table, the satellite 7 with the finished part collides with the table on the guides of the upper platform 15 of the lever. From this point on, the machine cycle begins with an automatic change of blanks. It is implemented as follows. The lever 13 is rotated 180, the platform 14 is moved upwards with the companion satellite with the workpiece on it, which is then shifted to the machine table, and the new cycle of the workpiece processing is activated by command. At this time, the slide together with the lever moves to the leftmost position, in which the lever pad 15, which now occupies the lower position and carrying the satellite with the finished part, is aligned with the left branch of the conveyor 8 and this satellite through the hydraulic cylinder 22 moves to the conveyor in the direction indicated an arrow. At the same time, the outermost satellite 7 of this branch is shifted to the upper guides 18 of the trolley 17. The trolley along the lower guides 19 is moving. At the same time, to the right, the lever 13 moves to the right to the middle position so that its lower platform is aligned with the right branch of the conveyor. The hydraulic cylinder 24 is then turned on, and all the satellites on the right are moved forward one step so that the outermost one is on the lever pad, and the trolley is released and moves to the left. The cycle for changing one workpiece is completed, and after finishing the machining of the part located on table 5, the entire specified work cycle is repeated. The machine works without the human being until the workpieces 11669654 are machined and only finished parts are located on the conveyor belt in the adapted space.
