Description

The invention relates to mechanical engineering, in particular to automatic lines for machining shaft-type parts.

The purpose of the invention is to simplify the design of the automatic line and expand its technological capabilities.

The goal is achieved due to the fact that the recognition device of the machined parts is made in the form of an elastic probe mounted on a roller located across the transporting device and hinged on racks, with the flag interacting with the position sensor at the free end of the roller

machined parts; in fig. 3 shows a section BB in FIG. one; FIG. 4 is a section B-B in FIG. one.

An automatic production line consists of machines 1-5, auto operators 6-10, transporting devices 1 I.

On the loading and unloading positions I, II, III, IV, V of the transporting device 11 there are sensors for the presence of blanks 12-16 and sliding stops 17-21. Before loading and unloading positions II, III, TV, V of parallel machines 2-5 in the direction of movement of parts (along arrow D on the transporting device II, devices for recognizing machined parts 22–25 are installed. the unloading position T of the machine 1 is due to the fact that only raw parts are transferred to the machine 1, the first of the parallel working machines, the transport device 11.

The detachable stops are electrically connected with the control systems of the auto operators and the recognition devices of the machined parts 22-24 in such a way that, when machining the parts on the machines 1-4, the sliding stops 17-20 let the flow of the parts carried by the conveyor device 11 unhindered.

Retractable stop 21 is electrically connected to the auto-1250A421 control system.

 the operator 10 and the recognition device of the machined parts 25 so that the retractable stop 21 only passes the machined parts regardless of whether the machine 5 is working or turned off. Thus, at the loading and unloading position V of the machine 5, the raw part is retained until the machine

5 will not process its program. This is due to the fact that the loading and unloading position V of the machine 5 is the last position in the robotic production line, and all

parts coming off the line must be machined.

Processing sh.pitsevyh shafts on parallel working machines 1-5 is as follows.

The unprocessed parts are transported by the conveyor device 11 to the loading and unloading position I of the machine 1, where they are held up by the extendable stop 17. The presence sensor of the workpiece 12 commands the auto-operator 6 to process a given program.

Auto operators 6-10, used in the automatic line, two-handed

(type Pirin series 510, A-91, etc.). Programs of auto operators 6-10 are of the same type; Removing the part from the machine with one hand, transferring the part to the transport device 11, removing the zagotonok from the transporting device 11 with the other hand of the operator, placing the part with the first hand of the operator of the part on the empty seat of the transporting device 11, transferring

blanks to the machine, installation of blanks in the machine.

After the program has been developed by the auto operator 6, the machine 1 is put into operation and the auto operator control system

commands the retractable stop 17, which frees the path to the flow of parts carried by the conveyor device 11. After finishing the machining of the part on the machine I, the control system of the auto-operator 6 issues a command to the retractable stop 17, which, srabsha, retains the raw part (workpiece) at the loading and unloading position I. Next cycle

the operation of the auto operator 6 and the machine 1 is repeated.

The parts are moved by the transport device 11 to the loading and unloading station.

load position II of the machine 2. Before the loading and unloading position II of the machine 2, the parts are in contact with the machined parts recognition device 22. When the machine 2 is working, the sliding stop 18, regardless of the signal coming from the machined parts recognition device 22, freely allows the flow of parts to the loading and unloading position of TIG machine 3; When the machine is inoperative 2 (part processing is completed), the part is transferred to the loading and unloading position II by the transporting device 11, interacts with a recognition device for machined parts 22, the signal from which controls the sliding stop 18: if the part is machined, extendable stop 18 unimpededly passes it to the loading and unloading position III of the machine 3, if the part is not processed - delays it at the loading and unloading position II machine

2. After a delay, the parts on the boot from parallel working stan30

but the unloading position TI of the machine triggers the sensor on the preform 13, which gives the auto-operator 7 a command to process the program, the end of which turns on the machine 2, and the control system of the auto-operator 7 issues a command to the sliding tool 18, which works to ensure the uninterrupted flow of parts (and processed and not worked 35) to the loading-unloading position I l of the machine 3. Machine 3 with an auto-operator 8, a work availability sensor 14, a sliding stop 19 and a recognition device processed 40 children Aley 23 and machine 4 with auto-operation, rum 9, workpiece presence sensor 15, sliding stop 20 and recognition sensor. Processing 1x parts 24 works in the same way as machine 2 with 45 auto operator 7, workpiece presence sensor 13, retractable stop 18 and device recognition of the machined parts 22, the operation of which is described above. After the machine 4, the flow of parts (processed and untreated) is transferred by the transport device 11 to the loading and unloading position V of the machine 5, in front of which the recognition device of the processed 55 parts 23 is installed. The recognition device of the processed parts 25 will interact with the portable transport device: O - 50

Now, the stop 21, with (a machined part, pushing the stop 21 prevents the part from moving; when it is not working (P1oGg of the part, the sliding stop 21 stops it on the loading and unloading position V of the machine 5. When there is a workpiece on the load-breaking position V of the machine 5, the workpiece sensor 16 includes an auto operator 10, which processes the program, after which the machine 5 starts up, after the completion of the processing of 1 SCLL of the operation of the machine 3 with the auto operator 10 is repeated.

Thus, the operation of the extendable stop 21 located at the loading and unloading position V of the machine 5 is determined by the operation of the recognition device of the machined parts 23 and does not depend on whether the part is machined on the machine 5 or not.

The recognition device for machined parts works as follows.

When the untreated (smooth) shaft passes under the recognition device of the machined parts, the 2fS probe rests against the smooth surface of the shaft and under its influence elastically deforms (bends), slips 1g-; on the surface of the vape, In this case, the roller 27 of the device for recognition of the machined parts remains ; 1 pinch or rotates by a slight angle and (Bar 28, is connected with it, does not enter into the throat of the position sensor 29, and the signal is not sent to the retractable stop, which ensures a delay of the untreated part ;: from the boot-GOVERNMENTAL razgruzoch- gtozitsit :.

1111I passing under the device p; 1g:; marking the machined parts of the bank with the spline The slope 26 is embedded in one of the shaft LrnmeB and the rail 27 is rotated at a considerable angle. In this case, the flag 28, turning, enters the slot of the position sensor 29, and the signal from it is fed to the sliding stop, which allows the machined part to pass through the loading and unloading operation: 1i. Dp preventing tipping of the probe 26 when it interacts with the splined shaft moved by the transport device 1 1, and also to set the probe 26 in the working position on the roller 27, a pin 30 is provided, which cooperates with the stops 31, 32 with fixed bolts 33, FOR the bracket 35. To ensure adjustment of the lugs 31, 32, annular grooves 36 and 37.10 are made in the bracket 35. The doe of which is designed as a probe
