Abstract

The utility model discloses a circular seam welding machine in the field of welding tool, which is comprised of two parallel rollers on the same plane. In addition, both ends of the roller are fastened with supporting saddle by means of bearings. The same side of two rollers is equipped with chain wheel. Here, two wheels are wrapped with chains. Axial side of two rollers is configured with power input unit, which is accessible to any roller in transmission. During operation, it is proposed to horizontally lay the annular metal pipes to be welded between two rollers. Thus, power input unit drives two rollers to work synchronously. At this time, the workpiece laid on roller will rotate along rollers to make weld joint run continuously and evenly. Welding torch fixed on the side of weld joint is stand still to ensure constant welding angle and even relative moving speed and continuously complete joint welding. Therefore, the utility model boosts welding speed, quality and productivity and features great safety and reliability and is suitable for circular seam welding of large-sized workpiece.

Description

Circular seam welder

Technical field

The utility model relates to a kind of auxiliary welding equipment, particularly a kind of welding aid that is used to weld girth joint.

Background technology

In the prior art, be the welding girth joint, when especially welding the girth joint of large-scale metal material, need frequent mobile welding torch position, be difficult to carry out continuous welding, also need turning of work piece in the welding process, by artificial turning of work piece, its smoothness, uniformity and security can not get all guaranteeing that cause speed of welding slow, welding quality is not ideal enough.

The utility model content

The purpose of this utility model provides a kind of circular seam welder, can improve speed of welding and welding quality.

For achieving the above object, the utility model provides a kind of circular seam welder, it is included in two cylinders that are arranged in parallel on the same horizontal plane, the cylinder two ends are installed on the bearing through bearing, two cylinder homonymy ends are respectively equipped with sprocket wheel, be wound with chain on two sprocket wheels, axle head one side of two cylinders is provided with power input device, is in transmission connection between power input device and arbitrary cylinder.

During the utility model work, the endless metal pipe level of needs welding is shelved between two cylinders, power input device work, driving one of them cylinder rotates, this cylinder drives another cylinder through chain and rotates, two cylinders turn to identical, rotating speed equates that the workpiece that is shelved on the cylinder also rotates with the rotation of cylinder, and promptly weld seam can evenly constantly rotate, and welding gun can not move, like this, make welding gun be fixed on the side of weld seam, can keep stable soldering angle, relative moving speed is finished the welding of weld seam continuously uniformly; Can improve speed of welding and welding quality, work safety, reliable, labor productivity improves greatly; The utility model is specially adapted to the girth welding of large-scale workpiece.

Description of drawings

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is that the A of Fig. 1 is to view;

Wherein, 1 bearing, 2 cylinders, 3 chains, 4 sprocket wheels, 5 power input devices, 6 driving members, 7 workpiece.

The specific embodiment

As figure, be circular seam welder, be included in two cylinders 2 that are arranged in parallel on the same horizontal plane, cylinder 2 two ends are installed on the bearing 1 through bearing, and two cylinders, 2 homonymy ends are respectively equipped with on sprocket wheel 4, two sprocket wheels 4 and are wound with chain 3, can realize synchronous rotation, axle head one side of two cylinders 2 is provided with power input device 5, and 2 on power input device 5 and arbitrary cylinder are in transmission connection through driving member 6, and this driving member 6 can be chain, belt, gear etc.

During work, endless metal pipe (workpiece 7) level of needs welding is shelved between two cylinders 2, power input device 5 work, driving one of them cylinder 2 rotates, this cylinder 2 drives another cylinder 2 through chain 3 and rotates, two cylinders 2 turn to identical, rotating speed equates that the workpiece 7 that is shelved on the cylinder 2 also rotates with the rotation of cylinder 2, and promptly weld seam can evenly constantly rotate, and welding gun can not move, like this, make welding gun be fixed on the side of weld seam, can keep stable soldering angle, relative moving speed is finished the welding of weld seam continuously uniformly; The speed of welding height, welding quality is good.

Claims

1, circular seam welder, it is characterized in that: be included in two cylinders that are arranged in parallel on the same horizontal plane, the cylinder two ends are installed on the bearing through bearing, two cylinder homonymy ends are respectively equipped with sprocket wheel, be wound with chain on two sprocket wheels, axle head one side of two cylinders is provided with power input device, is in transmission connection between power input device and arbitrary cylinder.
