SU363562A1 - DEVICE FOR SIMULTANEOUS WELDING TWO ANGULAR SEAMS - Google Patents

Description

one

The invention relates to the field of the mechanization of welding angular straight and curved seams.

A device for simultaneous welding of two fillet welds is known, comprising a guide carriage with two interconnected bar bends with supporting copy roller rollers and welding torches.

However, the known device does not allow the automatic adjustment of the position of the welding torch when deviations of the planes forming an angle are made for welding angular curvilinear joints of large length.

To improve the quality of welded joints by keeping the electrode position unchanged relative to the welded joint, the proposed device is equipped with burner displacement mechanisms, each of which is designed as a body rigidly strengthened on the corresponding rod with mounted on it with mutually perpendicular movement two sliders one on the other, with each rod rigidly attached to the rod, interacting through two shoulders lever, hinged to the housing, with a stem mounted in the housing parallel to the slider stem and connected to a lever rigidly attached to the axis of the corresponding copy roller, with a bracket mounted on the upper slider

welding torch.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, side view; in fig. 3 — mechanism of displacement with the cover removed, general view; in fig. four -

the section along the A-A in FIG. 3; in fig. 5 - section bb on fig. 3

A device for simultaneous welding of two fillet welds consists of a rod / with a carriage 2 fixed on it with support rollers, a mechanism 3 for displacing the burners and a tension spring 4.

The carriage 2 is a structure consisting of three pairs of hinged rollers. Two pairs of rollers under the force of the own weight of the device are shown to the same note, and one pair under the action of the spring 4 - to the set. The carriage bracket 5 is rigidly connected with the housing 6.

The burner displacement mechanism 3 includes

The levers 7 and 8, which are connected by hinges 9 with the rods 10. The axes // the push rods 12 by the hinges 13 are connected to the levers. Rod pushers springs 14 are pressed to the floating slide 15 and / 6. The slider 15 has a output shaft 17, on which the bracket

(5) welding torch 19 is fastened. The mechanism is closed by a cover 20, a flexible casing 21 and clamped by a yoke 22.

The rod 1 is connected to the displacement mechanism by the hinge 23, and to the rod of the trolley 2-J by a floating slider 25.

The device works as follows.

Before starting welding, the device with the welding torch is set to its original position. As welding progresses, the support rollers are pressed against the panel and set.

The lever 8, rigidly connected with the roller, moves to one side or the other, withdrawing the rod 10 after itself, and the latter, acting on the lever 7, leads the rod 12 connected with the slider 15 and the burner 19.

Due to the appropriate selection of the ratio of the arms of the lever 7 relative to the axis 11, all movements with any deviations occur so that the axis together with the housing 6 moves in one direction or another, and the burner fixed on the shaft 17 of the slide 16 constantly remains in starting position for welding.

The inclined position of the welding torch along a curved seam is ensured by a hinge 23 "slider 25.

Subject invention

A device for simultaneous welding of two fillet welds, comprising a guide carriage with two interconnected rods with supporting copying rollers fixed on the axes and welding torches, which, in order to improve the quality of the welded joints by keeping the electrode position unchanged, the relative welded the joint, it is equipped with mechanisms for displacing the burners, each of which is made in the form of a body rigidly fixed on a corresponding rod with mounted on it with the possibility of mutually rpendikul molecular movement of the two spring-loaded relative to the body slides arranged one above the other, wherein each slide is rigidly attached piston rod cooperating via a two-armed lever pivotally mounted on the body, with a rod mounted in the housing parallel to the rod of the slider and associated with a lever rigidly attached to

axes of the corresponding copy roller, with a bracket with a welding torch mounted on the upper slider.
