Description

one

The invention relates to welding, in particular to auxiliary equipment for assembly and welding works and can be used to assemble beams with flanges for welding.

The purpose of the invention is the expansion of technological capabilities by ensuring the assembly of beams with flanges located at different angles.

Figure 1 shows the device, a general view; figure 2 - node I in figure 1, the flange is installed under the angle to the longitudinal axis of the beam in a vertical plane; in FIG. 3 - the same, the flange is mounted perpendicular to the beam axis; figure 4 - section aa on fig.Z; in FIG. 3, view B in FIG. 3, at the time of assembly of the beam with the flange mounted, perpendicular to the longitudinal OCR of the beam in the horizontal plane; figure 6 is the same, the flange is installed at an angle to the longitudinal axis of the beam in the horizontal plane; 7 is the same at the moment of unclamping the clamping levers; on Fig the same, at the time of installation of the flange.

The device comprises a base 1 on which the fixing unit 2 for the beam 3 and the gripping unit 4 for the flange 5 are located. The gripping unit 4 is associated with a displacement mechanism designed as a slide 6 with a drive 7 for moving in the longitudinal direction in the horizontal plane.

The support 6 consists of two parts of an inclined plate 8 and a support 9 pivotally connected at an angle to one another. The hinged connection is made in the form of an eyelet 10 fixed on the inclined plate 8 and two eyelets; 11 fixed on the support 9. Eyelets 10

and 11 are mounted on a common axis 12 with a threaded end equipped with a nut 13 for fixing the inclined plate 8 when it is installed at the required angle. The support 9 is mounted on an annular protrusion 14 fitted with a bolt 15 with a nut 16 for fixing the support 9 after turning around the protrusion 14. Rotation of the support 9 around the protrusion 14 provides rotation of the entire gripping unit for mounting the flange 5 at an angle to the longitudinal axis of the beam Z. horizontal plane. In order to eliminate the displacement of the axis of the flange 5 relative to the axis of the beam 3, the gripping unit 4 is mounted with the possibility of lateral movement, for which the support 9 with the annular protrusion 14 is installed in the guides 17 perpendicular to the axis of the beam 3. - the bolt 15 and the nut 16 serve as displacement.

The studs 18 with springs 19 placed on them are screwed into the inclined plate 8. On the studs 18, the movable plate 20 is mounted for movement on them. The movable plate 20 is equipped with centering pins

21dl flange 5, arranged respectively openings, completed

in the inclined plate 8 and the flange 5. The movable plate 20 is connected to the drive

22 Node 4 Capture. The gripper assembly contains a rocker arm 23 connected by a fork 24 with a shaft 25 of the drive 22. On the rocker arm 23, the clamping arms 26. are fixed in rotation to the grooves 27, with which they interact with the fingers 28 mounted on the inclined plate 8.

When the flange 5 is installed at an angle to the longitudinal axis of the beam 3 in a vertical plane by means of a hinged joint, in order to eliminate the vertical axial displacement of the axis of the flange 5 relative to the axis of the beam 3, the gripping unit 4 for the flange 5 is mounted with the possibility of lifting by means of the rear. Cottages 29 screw-nut and 31 dove-tail guides. To secure the assembly 4 after this movement, threaded connection 30 is intended.

The device works as follows.

Before installing the beam 3 to be assembled, the inclined plate 8 is mounted at the required angle to the axis of the beam 3 in a vertical plane by means of a hinged joint. The resulting axial

welded flange 5. While clamping levers 26 divorced to the sides.

When the actuator 22 of the gripping unit 4 is turned on, the shaft 25 moves away from the end of the beam 3, to which the flange 5 is welded. Together with the rod 25, the rocker arm 23 moves.

with the clamping levers 25, the fingers 28 interacting with the grooves 27, due to which the levers 26, turning, approach the flange 5 and clamp it. After this, an actuator is turned on, which presses the caliper 6 onto the weld flange 5 against the beam 3, they are assembled by welding.

Then, when the actuator 22 is turned on, the rod 25 moves to the reverse one.

and the arms 26 are expanded. At the same time, the fingers 28 rest against the ends of the slots 27, and the rocker 23 with the arms extended 26 stops.

The movable plate 20, compressing the spring 19, moves along the studs 18 and moves away from the inclined plate 8 due to the power reserve of the rod 25, while the centering pins 21 emerge from the holes of the flange 5, freeing it from fixation. Thereafter, beams 3 are removed with a flange 5 welded to it. Then the support 6 is retracted by the actuator 7 to the initial position.

the displacement of the flange axis relative to the gg axis of the movable plate 20 is also returned by lifting or lowering the gripping unit 4 by means of the transfer 29 of the screw-nut. The fixing of the assembly 4 after this movement is carried out by means of a threaded connection .40 N 30.

to its original position, with the centering pins 21 protruding from the inclined plate 8. The levers 26 remain spaced apart.

The proposed device is distinguished with versatility by providing an assembly of beams with flanges located at different angles to the longitudinal axis of the beam, which, in comparison with the known, broadens the technological capabilities.

If necessary, install the flange 5 at an angle to the axis of the beam 3 in the horizontal plane node 4 capture, mounted on a support 9, rotate around the annular protrusion 14 to the desired angle. The resulting axial displacement of the axis of the flange 5 relative to the axis of the beam 3 is eliminated by moving the support 9 along the guide rails 17, and then fix the assembly 4 in this position With the bolt 15 and the nut 16 located in the groove of the guide 17.

The beam 3 to be assembled is installed in the fixing unit 2. Then, the centering pins 21 extended from the inclined plate are mounted

to its original position, with the centering pins 21 protruding from the inclined plate 8. The levers 26 remain separated to the sides.

The proposed device is distinguished by its versatility by providing for the assembly of beams with flanges located at different angles to the longitudinal axis of the beam, which, in comparison with the known, broadens the technological capabilities.
