Description

Positioning device for automatically welding inner circular seam of barrel

Technical Field

The utility model relates to a pressure vessel technical field, especially a barrel internal circumferential weld automatic weld's positioner.

Background

At present, in the manufacturing process of pressure vessels, the welding of longitudinal and circular seams of cylinder bodies is one of key processes, and many enterprises adopt automatic welding processes. Inner circular seams of end sockets at two ends of a cylinder body of the tank-type container are welded, one end of the cylinder body is open, and a cross arm in an operation frame of a cross arm type submerged arc welding machine extends into the cylinder body to carry out automatic welding. The other end is closed, namely the last final assembly inner circumferential seam, manual welding is generally adopted, the welding joint is in a Y-shaped groove form, the workload of manual welding in the cylinder is large, the working environment is poor, the working labor intensity is high, the efficiency is low, and the repair rate of the welding seam is high.

In order to achieve the above object, the utility model provides a following technical scheme: a positioning device for automatically welding an inner circular seam of a cylinder comprises a support fixedly connected with a submerged arc welding machine, wherein a roller fixing plate is fixed on the support, the roller fixing plate is connected with a connecting plate through a bolt, a roller shaft is fixed on the connecting plate, the top end of the roller shaft is sleeved with a roller through a bearing, the roller is arranged on a guide plate, and the guide plate is fixed on a switch magnetic base.

The utility model discloses a further improvement lies in: the top end of the roller shaft is provided with an elastic retainer ring for the shaft.

The utility model discloses a further improvement lies in: the bearing is a deep groove ball bearing.

The utility model discloses a further improvement lies in: the bracket is fixed with a roller fixing plate through spot welding.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses work load is little, and intensity of labour is little, and welding efficiency is high, realizes barrel inner circular seam automatic weld at last one, improves the problem that manual welding reprocesses the rate height.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment provides a technical scheme: a positioning device for automatically welding an inner circular seam of a cylinder comprises a support 1 fixedly connected with a submerged arc welding machine 10, wherein a roller fixing plate 2 is fixed on the support 1, the roller fixing plate 2 is connected with a connecting plate 3 through a bolt, a roller shaft 4 is fixed on the connecting plate 3, a roller 6 is sleeved at the top end of the roller shaft 4 through a bearing 5, the bearing 5 is a deep groove ball bearing, the roller 6 is arranged on a guide plate 7, and the guide plate 7 is fixed on a switch magnetic base 8.

The roller shaft 4 is provided at its tip with a shaft circlip 9, and is restricted by the shaft circlip 9.

The guide plate 7 is attached to the inner side of the cylinder 11 through a bolt connection switch magnetic base 8 for rail positioning, the guide plate 7 and the cylinder 11 are enabled to be coaxial and located on the same circumferential section, the support 1 is fixed on a submerged arc welding machine 10, the roller fixing plate 2 is connected with the support 1 in a spot welding mode, the submerged arc welding machine 10 and accessories enter the cylinder 11 through a manhole, the cylinder 11 rolls on a roller frame, the running speed of the submerged arc welding machine 10 is adjusted to be relatively consistent with the rotating speed of the roller frame, and the roller 6 is placed on the guide plate 7 to enable the submerged arc welding machine 10 to conduct automatic welding according to the running of a rail line. To accommodate the variation in the diameter of the barrel 11, guide plates 7 of different diameters may be designed to meet the requirements.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, article, or apparatus.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
