The invention relates to welding, in particular, to the construction of an automated production line for assembling and welding wheels from two workpieces, mainly tracked machines.

The aim of the invention is to increase productivity by reducing inter-operation time.

FIG. 1 shows an automated assembly line for assembling and welding from O two wheel blanks, top view; in fig. 2 - drive wheel in position before assembly and assembly; in fig. 3 — steering wheel in a position before assembly and assembly; in fig. 4 is a view A of FIG. one; in fig. 5 - the same, top view; in fig. 6 - section BB in FIG. four; in fig. 7 is a view B of FIG. four.

The line consists of the following main sections with the equipment installed according to the technological process.

The assembly section includes an inclined roller conveyor 1, a two-sided inclined roller conveyor 2, a sucker-feed conveyor 3, a device 4 for outputting drive wheel discs by one, a welding machine 5 for welding a disc to the hub, a transmission mechanism 6,

Lini works as follows.

In the manufacture of driving wheels, the blanks for the wheels from the roller table 1 are fed to the sucker conveyor 3 at its first position, where the device 4 for single-piece dispensing assembles a disk with a hub. In the next position, the welding machine 5 welds the disk to the hub, after which the transfer mechanism 6 pushes the hub on the lower conveyor 7.

Simultaneously with the upper inclined roller table 2 on the upper conveyor 7 enters the second billet wheels vedeyJ. In this case, the hook 22 engages the wheel blank, and the pneumatic cylinder 25 pusher 26 acts on the frame 20, which with its guide channels 21 interacts with the rollers 24 and drags the wheel blank on the lower conveyor 7. 23, they turn away and take up the initial position, and during the next working stroke of the cylinder rod move the locking step on the conveyor pitch.

The wheel blanks, located coaxially on different conveyors 7, move synchronously, maintaining this position. In the same

conveyors 7, hydraulic press 8 for 25 wheel blanks enter the drive wheel assembly area with a hydraulic press assembly hydraulic press 8, one

the workpiece falls on the fixed platform of the crosspiece 28, which extends 9 for the assembly of the guide wheels, the conveyor 10.

The welding section includes a welding unit 11 and a welding rotator 12 for welding wheels, a sucker conveyor 13 and elevating inclined directions 14.

The stripping section comprises a rotator 15 for stripping welds.

The control section contains a distribution table 16, a tray 17 for defective wheels and a tray 18 for finished wheels.

The conveyors 7 contain a metal structure 19, a box-like frame 20 with directions- channels 21, hooks 22 and gupps of horizontal single-acting ratchet dogs 23 fixed 40 coaxially with each other vertically on interconnected shtanga above the bearing planes of the conveyor, rollers 24 fixed metalwork 19, and the power cylinder 25 with the pusher 26.

The conveyors 7 for each of the wheel blanks 5 are located in one plane perpendicular to the base.

By lowering the plane of the lower conveyor 7, and 2Q of the other, the workpiece enters the platform 33, which is a continuation of the plane of the upper conveyor 7. When the wheel assembly operation is performed automatically or at the operator's command, the master cylinder 30 is activated, which pushes the inner bore 31 into the inner bore 31 It centers them, simultaneously pressing them together and assembles the wheel. At the same time, the pad 33, fixed on the rods of the pneumatic cylinders 32, moves downwards, since the pneumatic cylinders 32 at the same time release the air. The rods then move along the rollers 34. After the assembly operation is completed, the pad 33 leaves a little lower, and the conveyor 10 pulls the assembled wheel out of the press. In the next moment, the pneumatic cylinders 32 operate on the return stroke and return the pad 33 to the initial position. Thus, the master cylinder 30 returns to its original position after the wheel has been assembled. Next, the conveyor 10 moves the assembled 5Q drive wheel one by one to the area of the press 9, from where it is transported by the sucker conveyor 13 to the area of the welding rotators 12 and welding units 11 for welding the ring weld of the wheel.

Welding presses 8 and 9 contain a vertical frame 27, built into the metal structure of the conveyor 19. Traverse 28 is located at the level of the lower conveyor. The upper yoke 29, the main power cylinder 30 with a punch 31 and two lower cylinders 32, on the rods of which fixing the plane of the lower conveyor 7, and 2Q of the other, the workpiece enters the platform 33, which continues the plane of the upper conveyor 7. When the wheel assembly operation is performed automatically or at the operator's command, the master cylinder 30 is activated, which by the punch 31 inserts into the inner 25 bores of the wheel blanks, centers them, simultaneously pressing them together and assembles the wheel. At the same time, the pad 33, fixed on the rods of the pneumatic cylinders 32, moves downwards, since the pneumatic cylinders 32 at the same time release the air. The rods then move along the rollers 34. After the assembly operation is completed, the pad 33 leaves a little lower, and the conveyor 10 pulls the assembled wheel out of the press. In the next moment, the pneumatic cylinders 32 operate on the return stroke and return the pad 33 to the initial position. Thus, the master cylinder 30 returns to its original position after the wheel has been assembled. Next, the conveyor 10 moves the assembled 5Q drive wheel one by one to the area of the press 9, from where it is transported by the sucker conveyor 13 to the area of the welding rotators 12 and welding units 11 for welding the ring weld of the wheel.

The line is also designed for assembly.

The platform 33 is an extension of 55 and the welding of guide wheels having

Simultaneously with the upper inclined roller table 2 on the upper conveyor 7 enters the second billet wheels vedeyJ. In this case, the hook 22 engages the wheel blank, and the pneumatic cylinder 25 pusher 26 acts on the frame 20, which with the help of its guide channels 21 interacts with the rollers 24 and drags the wheel blank on the lower conveyor 7. During the reverse stroke of the cylinder rod 25, ratchet dogs 23, they turn away and take up the initial position, and during the next working stroke of the cylinder rod move the locking step on the conveyor pitch.

The wheel blanks, located coaxially on different conveyors 7, move synchronously, maintaining this position. In the same

the bottom of the conveyor 7, and the other, the workpiece enters the platform 33, which is a continuation of the plane of the upper conveyor 7. When the wheel assembly operation is performed automatically or at the operator's command, the main cylinder 30 is activated, which pushes the inner bores of the wheel blanks into the inner bores 31 their, simultaneously pressing them to each other and assembling the wheel. At the same time, the pad 33, fixed on the rods of the pneumatic cylinders 32, moves downwards, since the pneumatic cylinders 32 at the same time release the air.

Thus, the master cylinder 30 returns to its original position after the wheel has been assembled. Next, the conveyor 10 moves the assembled drive wheel one-by-one to the area of the press 9, from where it is transported by the sucker-rod conveyor 13 to the area of the welding rotators 12 and the welding units 11 for welding the ring weld of the wheel.

MO apply the appropriate quill, taking into account the specific profile of the wheel section. For this purpose, there is a second assembly unit in the line, designed for assembling guide wheels.

In the manufacture of the wheels of the guide blanks are on a two-level roller table 2, from where they are hooks 21 (upper and lower), by analogy with the described process of transporting the drive wheel, move to conveyors 7 and further to the area of the assembly press 9. the area of the press 8 of the assembly of the driving wheels and by means of the conveyor 10, which is similar in design to the conveyors 7, enter the area of the press 9. In this case, due to the difference in the outer diameters of the guide wheel blanks, the lower pushers 23 are displaced relative to the upper pushers in the direction of movement of the magnitude of this difference. Thus, the upper and lower ratchet dogs are combined into vertical groups in pairs. Ratchet Position

dogs in groups in the same way, which allows the billet-wheels to be moved coaxially to the assembly unit.

The assembly of the guide wheel is carried out similarly to the assembly of the drive wheel.

The welding of the ring shvov of the driving and guiding wheels is carried out by the devices 11 after turning the knots by the welding rotators 12 by 90 °. After welding, the assemblies along inclined guides 14 roll onto rotators 15 for cleaning welds, from where they are pushed onto distribution table 16 and then into production tray 18 of suitable products or tray 17 of defective assemblies, where minor defects of welding and casting are corrected.

If it is necessary to extend the range of wheels to be manufactured, a larger number of assembly plants can be built in line.

Thus, the invention allows to increase the productivity of the line, automate the assembly process of the units, as well as simplify the design of the assembly presses.
