Abstract

The invention relates to welding, in particular to devices for assembling and welding a cylindrical shell with a bottom, and can be used in welding shells with a bottom or rims of rollers of tracked propulsion units with disks. The purpose of the invention is to increase productivity and labor intensity. The device contained; 1a-1t stand 1, welding torch 19, clamping devices and accumulator 2 for feeding products 26B welding zone. The drive 2 is equipped with fixed stops 4 and mouths of the stops 5 from the welding zone MOVING1 to feed the assembled edition to the weld zone. Limiters 5 are installed with the possibility of reciprocating movement. Lever arms are provided to support the product during welding. Thanks to this, it is possible to combine transport and assembly operations, to cut tacks. 1 h, para. f-ly, 5 ill. p | B№4 01 W 25

Description

The invention relates to welding, in particular to devices for assembling and welding a cylindrical shell with a bottom, and can be used for welding shells with bottoms or rims of track rollers with

discs.

The purpose of the invention is to increase productivity by combining transport and assembly work.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - types of collected items.

Devices. 0 for assembling and welding the Shch1-hydride shell with the bottoms contains a frame 1, on which is mounted an accumulator 2 inclined in the direction of the welding position with a cut-off device 3 and fixed limiters 4 located on both sides of the storage device 2 along its entire length and represented guides, for example, round sections. The distance between the limiters 4, located on different sides of the accumulator 2, must be such as to ensure a guaranteed gap of no more than 1-2 mm between, and between them and the assembled product.

The drive 2 is also equipped with a slide. with the possibility of reciprocating movement from the pneumatic cylinder 6 along the guide 7. The movable stops 5 are sliding guides and in the extended position (shown in thin lines in Fig. 1) go to the welding position, being a continuation of the fixed limit stops 4. The distance between the movable limit stops 5, located on different sides of drive 2, should be the same as. the distance between the fixed stops 4.

A frame 8, consisting of levers 9 and 10, and an air cylinder 11, an orientation and attachment unit, consisting of a left headstock 12 with a clamping device 13 and a rotational drive 14 and a right headstock 15 with a clamping device 16, are mounted on the frame 1. , stop 17c by pneumatic cylinder 1d, burner supply unit 19, consisting of pneumatic cylinder 20, rotation of levers 21, pneumatic cylinders 22 of rise-lowering, on which burners 23 with copy rollers 24 and receiving chute 25 are attached. Welded product 26 consists of flexible sheet 27 and mortgage elements 28..

The device works as follows.

At the loading position, the operator assembles a cylindrical billet 27 with backfill elements 28, for example, inserts discs into the rim of a track roller. The assembled product is mounted on the drive 2 inclined towards the welding position between the left-handed and the right fixed limiters 4. The collector 26 rolls down the storage position 2 toward the initial position and is held on it by the cutter 3 and is held on it by the cutter 3. Since between the limiters 4 and product 26 is provided with a guaranteed clearance of no more than 1-2 mm, then product 26 freely rolls along drive 2, and the fixed restraints 4 protect the insertion elements 28 from being separated from the cylindrical billet 27, because elements 28 in the direction of their axis of rotation is larger than this gap.

If there is no product 26 at the welding position, the slam-shut 3 releases the product 26, which is in its initial position in the accumulator 2, and it shows. It moves to the welding position against the stop 17. In this case, the mobile stops 5 are in the extended position, being an extension of the fixed limiters 4, and prevent the separation of the embedded elements 28 from the cylindrical workpiece 27.

When the product 26 reaches the welding position, a command is given to bring the arms 9 and 10 of the gripper 8 to the product 26 in order to support the embedded elements 28. After that, by the pneumatic cylinder 6, the movable stops 5 are now- from the welding position, freeing up space for action clamping devices 13 and 16, which clamp the welded product 26, while giving commands to retract the grips 9 and 10 of the gripper 8, which secured the separation of the embedded elements 28 from the cylindrical billet 27 in the span of time when the
