Technical Field

[0001] The utility model relates to the technical field of steel plate welding, in particular to a butt joint device for steel plate welding. Background Art

[0002] In the prior art, a docking device is required when welding two steel plates. The existing docking device mainly includes a positioning plate with an arc-shaped groove in the middle. When in use, the steel plate is transported to the vicinity of the positioning plate by a conveyor vehicle. Workers move the steel plate to the positioning plate and push the steel plate to move on the positioning plate until the two steel plates are docked and a welding seam is left between the two steel plates. Welding can be performed from the docking point of the two arc-starting plates on the two steel plates. After completion, the steel plate can be moved down from the positioning plate.

[0003] However, in the above method, the steel plate and the positioning plate are in surface contact, and the friction between the two is very large, which makes it very laborious to move the steel plate on the positioning plate. Therefore, improvements are needed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a butt joint device for steel plate welding, which solves the problems mentioned in the background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A butt joint device for steel plate welding includes a positioning plate with an arc groove in the middle of the positioning plate. Two symmetrically arranged auxiliary moving mechanisms are installed on the positioning plate, and the two auxiliary moving mechanisms are respectively located on both sides of the arc groove. The auxiliary moving mechanism includes a mounting groove opened on the positioning plate, a rolling structure is installed in the mounting groove, and a locking structure is installed on the rolling structure.

[0007] In order to assist the steel plate to move on the positioning plate, the rolling structure includes a plurality of rollers arranged in the mounting groove. The rollers are arranged parallel to the arc-shaped grooves. The highest points of the rollers extend out of the mounting grooves. Rotating shafts are fixed at both ends of the rollers. The rotating shafts are rotatably mounted on the side walls of the mounting grooves.

[0008] In order to limit the position of the steel plate, each roller is provided with several locking structures, which include several slots opened on the surface of the roller. The multiple slots are arranged in a circular array on the roller, and a rod is inserted in one of the slots, and the upper end of the rod extends out of the slot.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the auxiliary moving mechanism can reduce the contact area between the steel plate and the positioning plate, thereby reducing the friction between the two, making it more labor-saving when the steel plate moves on the positioning plate, with a simple structure and high practicality.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1 , Figure 3 As shown, the utility model provides a butt joint device for steel plate welding, including a positioning plate 1, an arc groove 1-1 is opened in the middle of the positioning plate 1, two symmetrically arranged auxiliary moving mechanisms are installed on the positioning plate 1, and the two auxiliary moving mechanisms are respectively located on both sides of the arc groove 1-1. The auxiliary moving mechanism includes a mounting groove 1-2 opened on the positioning plate 1, a rolling structure is installed in the mounting groove 1-2, and a locking structure is installed on the rolling structure.

[0017] like Figure 2 , Figure 4 As shown, in order to assist the steel plate M to move on the positioning plate 1, the rolling structure includes a plurality of rollers 2 arranged in the mounting groove 1-2. The rollers 2 are arranged parallel to the arc-shaped groove 1-1. The highest point of the rollers 2 extends out of the mounting groove 1-2. A rotating shaft 3 is fixed at both ends of the rollers 2. The rotating shaft 3 is rotatably installed on the side wall of the mounting groove 1-2. Bearings can be installed on the side wall of the mounting groove 1-2. The rotating shaft 3 can be rotated by being assembled on the bearings.

[0018] like Figure 4 As shown, in order to limit the steel plate M, a plurality of locking structures are provided on each roller 2, and the locking structures include a plurality of slots 2-1 opened on the surface of the roller 2, and the plurality of slots 2-1 are arranged in a circular array on the roller 2, and an insertion rod 4 is inserted into one of the slots 2-1, and the upper end of the insertion rod 4 extends out of the slot 2-1.

[0019] The specific working principle of the utility model is described in detail below: the steel plate M is transported to the vicinity of the positioning plate 1 by a conveyor vehicle, and the worker moves the steel plate M onto the positioning plate 1 and directly pushes the steel plate M to move on the positioning plate 1. At this time, the roller 2 can rotate in the installation groove 1-2 through the setting of the rotating shaft 3. There is a line contact between the steel plate M and the roller 2, and the rotation of the roller 2 makes the friction between the steel plate M and the positioning plate 1 very small, which saves more effort to move the steel plate M. When the two steel plates M are butt-jointed, the butt joint is located at the arc shaped groove 1-1, and then insert an insert rod 4 into the slot 2-1 to block the outer sides of the two steel plates M to limit the steel plates M. Even if there is a distance between the insert rod 4 and the steel plates M, the steel plates M will not move easily on the positioning plate 1 due to their own gravity, and a welding seam is left between the two steel plates M. The two steel plates M can be welded from the arc-starting plate M-1. After the welding of the steel plates M is completed, the insert rod 4 is pulled out of the slot 2-1, and the steel plates M can be moved down from the positioning plate 1 more effortlessly through the roller 2.

[0020] Finally, compared with the prior art, the most important contribution of the utility model is that the auxiliary moving mechanism can reduce the contact area between the steel plate M and the positioning plate 1, thereby reducing the friction between the two, making it more labor-saving when the steel plate M moves on the positioning plate 1, with a simple structure and high practicality.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
