Abstract

The utility model discloses a circular seam welder in the welding tool field, including two cylinders of mutual parallel arrangement on same horizontal plane, the cylinder both ends warp bearing is installed on the support, and two cylinders homonymy tip do not is equipped with the sprocket, and two take turns to around there being the chain, and axle head one side of two cylinders is equipped with power input device, and power input device and arbitrary cylinder within a definite time transmission are connected. When the welding machine works, the annular metal pipe to be welded is horizontally placed between the two rollers, the power input device works to drive the two rollers to synchronously rotate, and a workpiece placed on the rollers also rotates along with the rotation of the rollers, so that a welding seam can uniformly and continuously rotate, a welding gun fixed on the side surface of the welding seam is not moved, a stable welding angle and uniform relative movement speed can be maintained, and the welding of the welding seam is continuously finished; the welding speed and the welding quality can be improved, the work is safe and reliable, and the labor productivity is greatly improved; the utility model discloses the girth welding of specially adapted large-scale work piece.

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.
