mi to the width of the diaphragm. After fixing the diaphragm, it is welded to the bottom sheet. Similarly welded other diaphragms. The clamps 4 are retracted and attached to the diaphragms of the lining on both sides. Sliders forward. At the same time, the rocker arms press the pads against the diaphragm, while the lever clamps 14 and I5 center the pads and press them against the pushers and Il3 rods of the pushers. After welding

the clamps are retracted again, the mouth is filled with the side sheets between the stops 3. By moving the sliders forward, they are pressed against the pads and diaphragms by the rocker arms and welded. Returning the clamps 4 to its original position, the product is removed from the stand. Thanks to this stand design, centering and fixing of diaphragms, linings and side sheets of box-shaped metal structures is provided. 7 il.

The invention relates to welding, in particular to ancillary devices for assembly welding, and can be used for assembling box-shaped metal structures made of sheet material with diaphragms under CBapiKy.

The purpose of the invention is to expand technical capabilities by providing an assembly for welding of metal structures with lining located on either side of each diaphragm.

FIG. 1 shows a stand, a plan; in fig. 2-4 - section aa in figure 1,. various working positions stevda | in fig. 5 is a view B in FIG. 4; Fig, 6 is a section bb In figure 4; Fig, 7. - section GG in figure 4,

The stand contains a support plate 1 with fixed supports 2 and 3 on it with two rows of clamps 4.

Each clamp 4 consists of a slider 5, movably mounted in a detachable housing 65i pneumatic cylinder 7, mounted on the housing 6 and connected by a rod (not shown) with the slider 5.

In the front part of the slider 5, the arm 8 is hingedly mounted and the pusher 9 is fixed, the lower arm of the rocker arm 8 being pressed by the spring 10 to the stop P located on the back side of the pusher 9.

In this case, the rocker arms 8 of the left row are made with grooves 12 on the upper shoulder and the right row on the upper and lower shoulders.

On both sides of the pusher 9, rods 13 are fixed with lever clamps 14 and 15 pivotally interconnected by a thrust 16, and one of the clamps is pivotally connected to a pneumatic cylinder stem / 17 mounted on a slider 5,

In order to make it possible to control the stroke 5 on its tail 18, a screw 19 is made.

The assembled metal structure consists of the bottom sheet 20, the diaphragm 21, the flanks 22 and the side sheets 23,

The stand works as follows. In the initial position, the rods of the pneumatic cylinders 7 and 17 of the chickpea, as a result of which the slider 5 is retracted, the lever clamps 14 and 15 are separated to the side, the rocker B in the spring 10 is pressed against the stop 11. The bottom sheet 20 of the product oriented with stops 2 and 3.

The inclusion of the pneumatic cylinder 7 serves the slider 5 of the right clamp 4, forward until the stop screw 19 into the housing 6.

In the grooves 12 inserts the diaphragm 21, set it on the bottom sheet 20,

include pnevmotsitshndr 7 left clamp 4. As a result, the slider 5 moves forward until the stop screw 19 into the housing 6, and the pusher 9 moves the diaphragm 21 to the pusher 9 right

pressing down. At the same time, the rocker 8 of the left clamp 4 with the lower shoulder rests against the edge of the sheet 20 and, turning around the axis and compressing the spring

10, 3; 3; 1) the edge of the diaphragm 21 (fig. 3) rides the upper arm by means of the upper arm.

The distance between the pushers 9 of the left and right clamps 4 is adjusted in advance by screws 19 to the width of the diaphragm 21. The diaphragm 21 is welded with the bottom sheet 20. Other diaphragms are also set and welded.

Then, the clamps 4 are returned to their original position and attached on both sides to the diaphragm 2 of the lining 22. Each slider 5 is fed forward. The crushing section 8 with the lower shoulder presses the lining 22 to the diaphragm 21 and, moving the slider further, Z. turns around 10. Lever clips 14 and 15 center the pads 21 relative to the diaphragms and press them against the pushers m .9 and the rods 13 (figure 4). Weld lining 22 to the bottom sheet 20 and the diaphragm 21.

The clamps 4 are returned to their original position, and side plates 23 are placed between the lugs 3 on each side between the lugs 3, and the plates 23 are pressed against the plates 22 and diaphragms 21 to the plates 22 and forward diaphragms 21 (FIG. 2). . After returning the clamps 4 to the original polis, the product is removed from the stand.
