00 The invention relates to a machine tool industry and is a milling automatic line with a through passage of parts through the machine tools and the movement of the milling headstock during the work feed. The line is intended for two-sided machining of parts such as a cylinder head, having a surface for gripping the conveyor 1, with their stops. The purpose of the invention is to simplify the design of a conveyor belt that provides the operation of the line. Simplifying the construction of the conveyor allows you to simultaneously increase the rigidity of the rods and reduce the metal consumption of lipid in general. FIG. 1 shows a diagram of the proposed line, a plan view; in fig. 2 shows a section of a shtangovny conveyor turning from a drive for clamping the device; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a view B in FIG. 1. A milling automatic line for two-sided machining of parts contains machine tools 1-5 installed along the technological process, interconnected by a section shtangovy conveyor consisting of sections with rods 6, main transporting lugs 7 and shtangamy 8 with additional stops 9. Rods 6 and 8 are associated with a longitudinal movement drive 10, and the shafts 6 are also connected with the rotation drive 11. The rod 8 is a sleeve with a key 12. The rod 8 8 sits on the axis 13 connecting the rod 6 located along both with torony from her. The rod 8 is covered by a split sleeve 14, which is provided with a groove for the pin 12 and is provided with an abutment 15. The sleeve 14 is mounted on a device for clamping the workpiece, on which is also attached a lever 16 provided with a groove. The lever 16 through the finger 17 t gi 18 interacts with the hydraulic cylinder 19 of the clamping mechanism. T he 18 is equipped with lugs 20 and 21. Machined on the conveyor part indicated by the position 22. The conveyor works as follows. Detail 22 enters the conveyor line. After machining the workpiece on the machine 1, the rod 6 with the transport stops 7 moves the workpiece 22 to an intermediate position between the machines 1 and 2. Next, the stops 7 turn from the workpiece and the section rods return to their original position. During the next conveyor run, the part 22 is moved from the intermediate position to the fixture of the machine 2. At this moment, 19 t ha 18 is moved from the hydraulic cylinder (in Fig. 3 to the right) and when the pin 17 interacts with the groove on the lever 16, the latter rotates and clamps the part 22 in the fixture . In this case, the ha 18 through the stop 20 hits the stop 15 of the sleeve 14 and turns it. The sleeve 14 through the key 12 transmits the torque to the rod-sleeve 8 and, accordingly, to the transport stops 9. The stops 9 are retracted from the part 22 at the time of its clamping in the tool. Next, the part 22 is machined on the machine 2, and the bars are returned to their original position. After processing the part, 22 tons of ha 18 by the hydraulic cylinder 19 moves in the opposite direction (in Fig. 3 to the left), the stop 20 moves down from the stop 15, and the stop 21 slides against the stop 15 and rotates it with the sleeve 14 counterclockwise, throwing the stops 9 on the part . At the same time, the part is pressed in the fixture and the additional stops are thrown 9. Next, the shanks move one step forward, the workpiece 22 processed on the machine is transferred to an intermediate position between machines 2 and 3, and later the machine is transferred to the machine 3. on the machine 4 with the participation of the rod 8 with additional stops 9 similar to the transfer of parts from the machine 1 to the machine 2. .m
