The invention relates to welding, in particular, to the design of an apparatus for assembly and rotation in the process of welding sectional pipe bends and other similar products.

The circuit of the invention is the simplification of the device design.

The goal is achieved by reducing the number of hinged joints and connecting rods of the mechanism for setting the movement of the faceplate.

FIG. 1 shows a device for welding sectional bends, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section b-B in FIG. 2

The device comprises a base 1 on which a drive 2 is placed, on the shaft of which a support ring 3 is mounted, supported on rollers 4. On the support ring 3, guides 5 are rigidly fixed in the plane of this ring, on which a slide 6, which interacts with a lead screw 7 connected to the drive 8 K of the slider 6 by means of a hinge 9, the axis of which is perpendicular to the axis of rotation of the support ring 3, is attached to the faceplate 10, on the support plane 11 of which a clamping device 12 is fixed. On the side surface The legs of the faceplate 10. with the ability to move in its supporting plane 11, a hinge 13 is installed, the axis of which is parallel to the axis of the hinge 9. The position of the hinge 13 relative to the faceplate 10 can be fixed using a stopper (not shown).

On the guides 5 there is also an installation movement mechanism for the faceplate 14 with a stopper (not shown) and an additional hinge 15, the axis of which is parallel to the axis of the hinge 9. The hinges 9 and 15 are located in one plane parallel to the support ring 3.

Hinges 15 and 13 are connected by a tie 16, the length L of which is equal

L, (L3

where Lj is the distance between the axes of the hinges 9 and 13;

LJ is the distance between the center of the clamping device 12 and the hinge 9;

R is the radius of curvature of the outlet; ot is the angle between the axes of two adjacent sections of the outlet.

T ha 16 is made telescopic

The device works as follows.

A weldable outlet is fastened to the faceplate with the aid of a clamping device 12. The device can be adjusted when resizing a weldable outlet — it can be made in two ways.

By changing the position of the center of the clamping device 12 on the plate 10 (for this purpose moving the clamping device 12) and changing the length of the rod .16, as well as the distance between the hinges 9 and 13, the adjustment of the rod 16 must be telescopic. After that, it is moved with the help of the actuator B and the lead screw 7 tons gu 6 with the hinge 9 until the welded joint becomes vertical. In this case, the axis of rotation of the joint is aligned with the axis of rotation of the actuator 2. During the welding process, the actuator 2 rotates the support ring 3 together with the faceplate 10 and the weld branch. After welding the first joint, all operations are repeated until the welding of all the outlet joints is completed. After welding all the joints, the tap is removed.

The proposed device has a simple design. The quality of welding is improved due to a more accurate installation of the welded joint to the desired position and the rigidity of the device is increased by reducing the number of hinges.
