The invention relates to mechanical engineering, in particular, to auxiliary equipment for assembly and construction works, and can be used, for example, for assembling beams with an inclined flange for welding.

The aim of the invention is to increase productivity by ensuring the simultaneous removal of the clamping levers and centering pins with a single actuator.

Fig, 1 shows the proposed device, a general view; FIG. 2 — node I in FIG. 1; Fig. 3 is a view A of Fig. 2, at the time of assembling the flange with the beam; in FIG. A, the same at the moment of unclamping the grippers; in FIG. 5, the same at the moment of installation of the flange; figure 6 is a section bB in Fig, 2,

The device comprises a base 1, on which the fixing unit 2 for the beam 3 is located and the gripper unit 4 4 for the flange 5. The gripping unit 4 is associated with a displacement mechanism made in the form of a support 6 with a drive 7 for its horizontal movement. The support 6 consists of two rigidly connected plates-: inclined 8 and horizontal 9; In the inclined plate 8, studs 10 are inserted with springs 11 placed on them; On studs 10, the movable plate 12 is mounted with a possibility, The movable plate 12 is provided with centering pins 13 for the flange 5, arranged respectively with holes made in the inclined plate 8,

The movable plate 12 is connected to the drive 14 of the gripping unit. The gripping unit contains a yoke 15 connected by a fork 16 with a shaft 17 of the actuator 14. The yoke 15 is fixed with the possibility of turning the clamping levers 18, The levers 18 have grooves 19, with which they interact with the fingers 20 mounted on an inclined plate eight,

The device works as follows.

The beam 3 to be assembled is installed in the fixing unit 2. Then, the centering pins 13 extended from the inclined plate are mounted with a weldable flange 5, the clamping levers 18 expanding.

When turning on the drive 14 of the gripping unit, its rod 17 moves to

the side from the end of the beam 3, to which the flange 5 is welded, together with the rod 17 the rocker arm 15 moves with the clamping levers 18, and the fingers 20 move along the slots 19, whereby the levers 18 turn to fit the flange 5 and clamp it ,

After that, the actuator 7 is turned on and presses the welded flange 5 against the beam 3 with a support 6 and is assembled by welding,

Then, when the actuator 14 is turned on, its brush 17 moves in the opposite direction and the arms 18 are expanded and the fingers 20 rest against the end of the grooves 19, and the rocker 15 with the separated arms 18 stops.

The movable plate 12, compressing the spring 11, moves along the studs 10 and moves away from the inclined plate 8 due to the stock of the stroke of the rod 17,

Then the caliper 6 is retracted by the actuator 7 to the initial position, the movable plate 12 also returns to its original position, the centering pins 13 protrude from the inclined plate 8,

After that, beams 3 are removed with a flange 5 welded to it,

The proposed assembly for welding a flanged beam allows for increased productivity by ensuring the simultaneous removal of clamping levers and centering pins for the flange with a single actuator.
