The invention relates to a machine tool industry and can be used in automatic lines with a stepper conveyor for mechanical multi-side machining of lengthy parts such as slats, square pipes, etc.

The aim of the invention is to increase line productivity by enabling the simultaneous loading of all machines from a single rotary drive, as well as by concentrating the processing operation and compact line arrangement as an aggre gantry machine with a rotary table.

Fig. 1 shows the proposed automatic line, a view in the plan; in Fig. 2, a view along arrow A in Fig. 1. with partial cut; on fig.Z - view 20 on one of the fixtures of the machine with the pressure device; figure 4 - section bB in fig.Z; figure 5 - section bb In figure 4; Fig. 6 is a view of grips with a suspension on a working position with machined parts; figure 7 - section GG in figure 6; on

Fig. 8 is a view of a pre-orienting device.

The automatic line contains the -, and - Deepening 34, intersectional position 1 with the resistors 7 7 of the device 4.

The clamp 6 (figs. 3 and 4) of the mount on the base element 5, made in the form of a horizontal connection of the displaced bar 22 and the plate at the assembly 4, is made up of studs 23 installed in the horizontal row in the housing of the device 4; a stop 24 and a gland 25, placed at the right ends of the casing of the device 4 and intended for error tolerance arising from the transportation of parts 21 from to the machine.

The gland 25 of the plate 26 with its slider 27 spring-loaded, connected by cylinders 28 and 29 displaced by a horizontal guide 30

For processing on the line of detail of other sizes, it is extremely re, the first from adjusting 24, the clamp 23 is provided with an additional adjustment installed on it with an abutment 32 and has a protrusion 33 in the wedge (figure 5), interacting with the same recess 34,

load position 1 with the device 2 loading and installed in the technological sequence of machines 3 with clamping devices 4, consisting of the base element 5 and clamps 6, and the transport device 7 (Fig 2,3,4).

The transport device 7 is formed by a rotary table 8 with levers 10 mounted in a vertical plane from the cylinder 9 in the form of frames; by the end of each of the levers on the suspensions 11 are mounted and attached to the traverse

12 clamps 13, made in the form of double-arm levers. The suspensions 11 (Fig. 7) are made in E1id of the rods 14 with a conical collar 15, spaced O in the holes 16 of the crosshead 13, a spring-loaded spring 17 with the lower conical part 18 of the holes 16 to the counter surface of the shoulders 15 through the stop elements 19 mounted on supports 20 rolls. Such a suspension design allows plane-parallel movement of the crosspiece 12 with levers

13 and parts 21 within the clearance of Fr.

Automatic line work as follows.

After working off the power units on the machines 3 of the next cycle, the loading command is received on the appropriate controls (not shown).

The parts are unclamped on the machines 3, the levers 10 are raised by the cylinders 9 to the uppermost one. living The turn of the trawler of the tailor device 7 is made through the rotary table 8.

At loading position 1, loading device 2 delivers parts 2 to the zone of action of the transport device 7. Lever 10, lowering, gives grippers 13 to parts 21. For this purpose, lever 10 with grips 13 n suspensions 11 installed and ground on the traverse 12, by gripping the parts 21, rises to the upper position until it stops.

and recess 34, attachment tool 22 22.

The clamp 6 (Figs. 3 and 4) is mounted on the base element 5, made in the form of a connection of a horizontally placed strip 22 and the plate of the device 4, composed of tacks 23 installed in a horizontal row in the housing of the device 4. The stitches 23 are located between an adjustable stop 24 and a pressure device 25 placed at the opposite ends of the casing of the device 4 and designed to eliminate errors that occur when transporting parts 21 from the machine to the machine.

The pressing device 25 consists of a plate 26 with a slider 27 spring-loaded with respect to it, associated with the cylinders 28 and 29 of their movement along horizontal guides 30 and 31.

For processing on the line of parts of other sizes, at least the first from the adjusting stop 24, the tack 23 is provided with an additional adjustable stop 32 mounted on it and has a protrusion 33 in the form of a wedge (FIG. 5) that interacts with the same recess 34, is complete

and recess 34, attachment tool 22 22.

The loading device 2 comprises pre-orienting spring-loaded lodgments 35. The grippers 13 are connected in pairs by cylinder 36.

Automatic line works as follows.

After testing by the power units on the machines 3 of the next cycle, the i-load command is received from the corresponding controls (not shown).

The unclamping of the parts 21 on the machines 3 is performed, the levers 10 are raised by the cylinders 9 to the uppermost position. The turn of the transport device 7 is produced by turning the table 8.

At loading position 1, loading device 2 delivers parts 21 to the zone of operation of the transport device 7. Lever 10, lowering, brings the grippers 13 to parts 21. After that, the lever 10 with the grips 13 on the suspensions 11 mounted and fixed on the yoke 12, seizing parts 21, rises to the top position until it stops.

The transport device 7 is rotated again by the rotary table 8. The parts 21 from loading position 1 are above the working position of the first machine 3. A command is received to feed the parts, 21 to the device 4. The levers 10 feed them to the base elements 5 in the form of strips 22 with clamps 6 After that, for exact orientation of the parts 21 to be machined, a spring-loaded slider, 27, driven by cylinder 28, moving along horizontal rails 30, brings parts 21 to an adjustable-15 sequence of machines with clamping

the fixed (fixed) stop 24, then they are clamped by clamps 23 mounted in a horizontal row in the housing of the device 4,

The orienting of the parts 21 in the base elements 5 of the devices 4 is carried out due to the gap between the curing in the suspensions 11. The springs 17 are then compressed in arrangements with basic elements and claws and a transport device including a rotary table and located on the underside of 20 table hangers spring-loaded bars with grippers, characterized in that, in order to expand technological capabilities, the transport device is provided radially

The collar 15, the rod 14 is separated from the 18 openings 16 placed on the turntable with the lower conical part 18 also with a certain gap. In the process of transferring the parts 21 with the gripping arms 13 of the spring 17, the conical shoulder 15 is gaplessly connected to the lower, counterpart 18 of the holes 16 of the crosspiece 11 through the stop elements

19 mounted on rolling bearings

20, preventing vibrations of the parts being carried.

the ability to rotate in a vertical plane levers and cross-beams, right this grippers are made in the form of pairs of two shoulders, pairs of which

30 are mounted on each traverse in a section and each traverse is connected by a foundation with a rotary table lever, each clamping device made in the form of a horizontally placed on the base element of the strap, the clamps are arranged in a row, and ONE of the stitches is equipped with an adjustable one. emphasis with height in the form of a wedge, races

After the machining of parts 21 is completed, the described cycle of their transfer to the second and then to the third processing machines and the unloading position is carried out on the first machine 3 line.

If it is necessary to process parts of a different length (for example, a shorter one), the line is automatically rebuilt upon a command from the control panel. At the same time, one of the tacks 23 with an additional adjustable stop 32 is lowered as for clamping the parts and is oriented in the housing of the device by connecting its 50 with a conical collar placed in

a wedge 33 with the same recess 34, embodied on the vertical bar 22. The pressing device 25 is also rebuilt by horizontal transfer of the plate 26,

moved by the cylinder 29 along horizontal guides 31 together with a spring-loaded slider. 27 and its movement device (cylinder 28 and guides 30).

The processing cycle on the line after adjustment for processing another part is similar to that described.
