Problems solved by technology

Because the cylinder will inevitably produce axial movement deviation during the rotation process, the position of the actual welded seam will deviate from the position of the circular seam of the cylinder, resulting in welding deviation and affecting the welding quality

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] Such as figure 1 , 2 , 3 and 4, the submerged arc welding synchronous follow-up device of the present invention includes a bracket 2 supporting the welding trolley 1, a clamping drive device 3, and a connecting plate 4.

[0023] A track 21 is provided on the bracket 2 , and the trolley 1 can slide along the track 21 toward or away from the barrel 5 , and the welding torch head 11 protruding from the trolley 1 is located on the annular seam 51 of the barrel 5 . One end of the clamping drive device 3 is clamped on the edge plate 52 of the cylinder 5, and the other end is fixedly connected to the trolley through a connecting plate 4, so that there is no relative displacement between the tr...

Abstract

The invention discloses a submerged-arc welding synchronous follow-up device, which comprises a welding gun head extending out of a welding machine trolley, and is characterized in that: the welding machine trolley is connected with a clamping driving device, and the clamping driving device is clamped on an edge plate of a cylinder body by two bearings; and when the cylinder body rotates along a central shaft of the cylinder body to generate axial displacement, the welding machine trolley and the welding gun head on the welding machine trolley moves in the same displacement. The submerged-arc welding synchronous follow-up device has a simple structure; when the cylinder body rotates along the central shaft to form the deviation of axial motion, a submerged-arc welding machine and the cylinder body move axially by the clamping linkage device, so that relative displacement between the submerged-arc welding machine and the cylinder body in the axial direction is avoided; and the free rotation state of the cylinder body can be kept continuously by the clamped bearings, relative movement between the submerged-arc welding machine and a circular seam is avoided, the phenomenon of welding deviation is avoided, and the welding quality is improved.

Description

technical field [0001] The invention relates to a welding fixture, in particular to a submerged arc welding synchronous follow-up device. Background technique [0002] When using submerged arc welding to weld workpieces, the position of the submerged arc welding machine is usually fixed, and the workpiece is automatically moved to realize the welding of the weld, or the position of the workpiece is fixed, and the submerged arc welding machine automatically moves to realize the welding of the weld. When carrying out girth welding to the cylinder workpiece, the cylinder is usually rotated, and the girth welding is performed by a submerged arc welding machine arranged at a certain point. Because the cylinder will inevitably produce axial movement deviation during the rotation process, the position of the actual welded seam will deviate from the position of the circular seam of the cylinder, resulting in welding deviation and affecting the welding quality.
