Abstract

The invention relates to the processing of metals by pressure, in particular to devices for moving and orienting heavy workpieces. The aim of the invention is to increase the productivity of the process of movement and orientation and reliability of operation. The blanks are mixed and oriented by a platform 35, movable in a horizontal direction and rotatable around a vertical axis. The platform is fixed on a vertical shaft installed in the feed carriage 2. The vertical (rotary) shaft is rotated when the friction ring interacts with the spring-loaded friction planks 42, and are fixed to the frame. The rotation of the vertical shaft with the platform is limited by the rotation restriction mechanism. The rotation restriction mechanism includes a protrusion located on the disk and stops mounted on the feeding carriage with the possibility of adjusting movement and interaction with the protrusion 1M. The feed carriage is driven by a cable wound on the drum 21. The drum is mounted on the driven shaft, which carries the driven scraper. The driven brushwood, through a converting mechanism, is connected to the power cylinder 3. The device provides transportation and orientation of the workpieces between technological machines with high speed and positioning accuracy, and allows orienting parts under any yro.i 7 Il.

FIG. 6 - section D - D in FIG. one; on ; FIG. 7 is a section H - E in FIG. 2.; The device comprises a frame 1, a charging carriage 2, a power cylinder 3 with HITOKOM 4, a driven gear rack 5, a finger 6, mounted on the rod 4, 5 and 7, connected with a finger 6. The drive gear-; This lath 5 is movably mounted on the tg 7, i is spring-loaded relative to it by a thread; 1 and it engages with the three-wheel drive and the first 9. It is located at KOpiiy-; Section 10 and mounted on a new shaft. P. Shaft 11 is installed in the Cornus i (i on: bearings 12. On the shaft 11 is fixed a curve: pin 13, on which the slider is installed 14 s; the possibility of adjusting the offset from the screw 15. The slider 14 is a glarnarno gv -; engaged with the connecting rod 16, on which the camshaft is movably mounted. 17. Nol; zun 14 is connected with the connecting rod 16 via a curved pin; finger 18. The gears of the rack 17 go-; dit. driven gear 19, I mounted on the driven shaft 20, carrying the drum 21. The toothed rail 17 is installed in the housing 22, freely mounted I to shaft 20 with bearings 23. Bar-I ban 21 is connected to shaft 20 with screw 24. Cable 25 is wound on a drum and: secured with strips 26. On frame 1 are mounted; with the help of rollers 28 and 29 the feed carriage 2 moves. The feed carriage 2 comprises a housing 30, axes 31 for mounting the rollers 28, a shaft 32, mounted vertically in the housing 30 on the support 33. : Lu 32 p. Mounted disc 34 and pad 35 ic by limiters 36 for the workpiece (not shown). In the housing 30, the stops 37 are installed with the possibility of adjusting movement, and on the disk 34, a support 38 is fixed. The cable 25 is connected to the feeding carriage 2 by means of the clips 39. On the frame. installed blocks 40, through which threw the cable 25.

On the slab 4 of the frame 1, the mounting strips 42 are installed. The latter are pivotally mounted on two shoulders 43, which are mounted on brackets 44 by means of pins 45, Levers 43 are spring-loaded springs 46 and E borrowed from adjusting screws 47. Adjustable length stops 48

and sensors 49. On disk 34 is fixed friction ring 50.

The device works as follows. Release the screw 24 and turn the drum 21 install the carriage 2 with the workpiece against the grips of the robot (not shown). The drum 21 is secured with a screw 24. Then the carriage 2 is moved to another position and by adjusting the stroke 4 of the cylinder 3 or the size of the shoulder of the curve 13, moving the slider 14, set the length of the movement of the carriage 2. Then place the sensors 49. Place the workpiece in the receiving section carriage 2.

The sensors 49 include an electromagnet

 pneumatic distributor (not shown) and lindr 3 moves both slats 5 and 17 with crank 13 to another position. The speed is non-repeat, yen rail 17 and, accordingly, the rotation of the drum 21 occurs smoothly, grows to a maximum value in the center

0 stroke, then gradually decreases due to the fact that the crank 13 makes half a turn from one dead point to another. The carriage 2 therefore moves smoothly and stops smoothly without knocks and jerks. Since the rack and pinion gears are made without lugs, the rails 5 and 17 are spring loaded by springs. The carriage 2 stops exactly at the end positions without additional stops and dampers.

The billet is taken away, the sensors 49 give the co-driver the electromagnet of the pneumatic distributor and the carriage 2 moves to the initial position. The speed of movement of the carriage 2 pe1L is controlled with the help of air throttles (not shown).

The orientation of the receiving platform 35 of the carriage 2 takes place in this way. Friction strips 42 using adjusting screws 47 are installed on the angle of inclination of the strips 42 and respectively on the length of the contact of the friction planks 42 with the friction ring 50 of the disk 34.

0 When moving the carriage 2, the friction ring 50 contacts the friction plate 42 and, due to the frictional forces, rotates, turning the receiving platform 35 with the workpiece to the required angle. When the carriage approaches a different position, the friction

 the ring 50 comes into contact with the other friction strap 42, turns to the contact of the movable stop 37 with the fixed stop 38. The rotation angle of the disk 34 is adjusted by moving the movable

 stops 37 in the carriage 2.

  The proposed device provides transportation and orientation of the blanks between technological machines with high speed and positioning accuracy and allows to orient parts to

five . angle. A quick changeover to another workpiece and simple adjustment allows you to expand the technological capabilities of the device.

As a result of jerking and strikes during operation, durability is enhanced. By simplifying the changeover operation to other parts, the service of the device has been improved.
