On the table 7, a power cylinder 48 is installed for resetting the control gears 49 and the discharge tray 50.

The welding head 18 contains a torch 51 mounted on a platform 17, In the front part of the platform 17 there are rollers-52 in contact with copiers 22. In the upper part of the platform 17 brackets 53 are installed, in slot d of which on the axis 54 a rocker arm 55 is installed. the rocker arm 55 is mounted with the rollers 56, and the other end of the rocker arm is connected via a stretch spring 57 to the bracket 53, the Parameter control unit (not shown) of the control gear 49 has the ability to connect to the control gear 49 t 21.

The device works as follows

After the control gear 49 is loaded into the cradle 21, the power cylinder 23 moves the cradle 21 along the guide 20 resting on the supporting table 3 into the work area and after reaching the leftmost position, the power cylinders 39 and 40 are alternately operated, first preliminarily fixing the control gear 49 and then in the same 20 revolutions electromotor; atel 42 according to

the sequences eliminate the gaps in the magnetic system by certain efforts and thereby reach the required electromagnetic parameters of the control gear 49,

The forces from the power cylinders 39 and 40 are transmitted to the control gear 49 through the hinges 38 with the corresponding clamps 36 or 37 moving along the guides 34 closed by the covers 35,

After the final clamping of the control gear 49, the direct-current motor 42 is turned on, the torque from which via the belt drive 43, the support 41 and the chain gear 44 is transmitted to the sprockets 45 mounted on the output ends of the spindle screws 10, the tension of the chain gear 44 is carried out - placing the sprocket 46 of the tension device 47. The spindle screws 10, rotating in the bearings AND and interacting with the code nut 43, move the carriages 12 and together with them the welding heads 18 to the welding zone. The carriages 12 move in the sliding bearings 16 along the guides 8 and 9 inside the housing 2. At the same time, the springs J9, acting on the welding heads 18 as the rollers 52 pass over the copiers 22, bring the special torch 51 closer to the welded control gear 49,

After reaching the required clearance between the electrode of the burner 51 and the edges of the control gear 49 to be welded, the roller 56 is turned

Shifting in the groove d on the axis 54 together with KopOMi icjiOM 55 under the influence of the spring 57, pressing the welded edges of the control gear 49 with a certain force. The force of pressing the edges is controlled by the position of the second end of the pr 57 in the bracket 53 and the welded edge of the control gear 49, the accelerated movement of the carriages 12 ends and translates to welding speed.

At the same time as the start of operation of the power cylinders 39 and 40, the supply of protective gas is turned on, which is turned off after the arc is extinguished. The welding speed is controlled by changing

cost of current. After the r-arc of the arc, the direct-current motor 42 switches to higher revs and welding heads, moving along

5, the guides 15 are retracted from the control gear 49 due to the interaction of the rollers 52 with the copiers 22. At the same time, the carriages together with the platforms 17 and the welding heads 18 move to the extreme left position and stop.

The power cylinders 39 and 40 take off the force from the welded control gear 49, then the power cylinder 23 moves the cradle 21 with the welded control gear 49 to the extreme right position through the window a of the sidewall 4, where the power cylinder 48, will act with my rod through the pusher on the roller 32 of the lever 31, rotates the shaft 29 together with the levers 28 rigidly mounted on it. The control gear 49 rises, and after reaching the silo cylinder 23 of the upper position by the rod, it slides off along the upper edges of the levers 28 to l otok 50 reset.

After returning the rod of the power cylinder 23 to its original position, the levers 28 under the influence of the spring 30 return to their original position, t, e, below the level of the plates 24. At this time, the direct current electric motor 42 moves in the opposite direction and accelerates the carriages 12 together with the welding heads. 18 to the extreme left where they stop.

During operation, the slider 21 is continuously cooled by supplying cooling water to the nozzles 25 into the channels c. As g slider 2I moves, its machined planes b slides along a T-shaped guide 20, while bracket 26 is supported and slides along rod 27.10

Further, when installing parts of the new startup apparatus 49, the cycle of operation is repeated.
