Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, in particular to a welding device. Background Art

[0002] See Figure 1 The part 10 shown includes a base 11 and a column 12. Both the column and the base are made of steel. The base 11 is provided with a plurality of mounting holes 111. During the production process, the bottom of the column 12 needs to be welded and assembled with the top surface of the base 11 to form an integral part. The column 12 and the base 11 have a certain connection position, and the column 12 and the base 11 are tilted. The current production process is to bevel the bottom of the column 12 to form an inclined surface, and then fit the inclined surface to the upper end surface of the base 11. The worker holds the column 12 by hand and positions it at the connection position of the base 11. Then, the worker uses the other hand to start spot welding around the column 12. After that, the hand holding the part rotates the column and the base, and cooperates with the welding gun to perform annular welding. This welding method has low welding efficiency, and the column is tilted. One hand supports the column and the other hand welds, which easily causes the column to deflect, which is not conducive to short-term, large-scale production. Summary of the Invention

[0016] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0017] In the description of this application, it should be understood that the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0018] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0019] See Figure 2-4As shown, the present application discloses a welding device, including a rotating assembly 20 and a positioning assembly 30; the rotating assembly 20 includes a driving motor 21, a turbine reducer 22 and a rotating platform 23, the main shaft of the driving motor 21 rotates, and after the start switch is triggered, the main shaft of the driving motor 21 rotates, and after being decelerated by the turbine reducer 22, it drives the rotating platform 23 to rotate in a certain direction at a certain speed. The positioning assembly 30 is fixed on the rotating platform 23 of the rotating assembly 20, and the rotating assembly 20 rotates on a fixed axis. The positioning assembly 30 includes a support rod 31, a vertical adjustment plate 32, a first support claw 34, and a second support claw 35. Specifically, the support rod 31 includes a first support rod 311 and a second support rod 312. The first support rod 311 and the second support rod 312 are both L-shaped. After the head end of the second support rod 312 is connected to the end of the first support rod 311, a frame structure is enclosed. Of course, the connection section between the second support rod 312 and the first support rod 311 is provided with an adjustment slot 313, so that the horizontal height of the second support rod 312 can be adaptively adjusted. The lower end of the first support rod 311 is fixedly connected to the rotating platform 23. The specific connection method can be bolted or directly welded to the rotating platform. The specific connection method can be adaptively selected according to actual production needs. The vertical adjustment plate 32 is provided with an adjustment slot 321. The first support claw 34 is movably connected to the vertical adjustment plate 32 and can slide along the adjustment slot 321. The second support claw 35 is connected to the vertical adjustment plate 32 via an adjustment member 33. The adjustment member 33 is provided with a slide slot 331. The second support claw 35 is movably connected to the adjustment key 33 and can move along the slide slot 331. The adjustment member 33 is connected to the vertical adjustment plate 32 and can move along the adjustment slot 321. Specifically, the first support claw 34 and the second support claw 35 are connected to the vertical adjustment plate 32 and the adjustment member 33 respectively via a first adjustment column 37 and a second adjustment column 38. The adjustment member 33 is connected to the vertical adjustment plate 32 via a third adjustment column 39. When adjustment is needed, it is only necessary to loosen the fixing nuts of the first adjustment column 37, the second adjustment column 38 and the third adjustment column 39 to make the first support claw 34, the second support claw 35 and the adjustment member 33 movable for adjustment. After adjustment is in place, tighten the corresponding nuts to fix them in position.

[0020] Considering the cylindrical shape of the column, in order to better fit the column to support and position it, this embodiment preferably has the first support claw 34 and the second support claw 35 both have a semi-cylindrical structure. The outer surface of the column can be attached to the inner surface of the semi-cylinder, supporting and positioning the column through its two sides. Of course, to ensure stability during the spin welding process and prevent the column from misaligning, this embodiment preferably includes magnets 36 on both the first support claw 34 and the second support claw 35. The magnetic force of the magnets attracts the column, keeping it in position against the first and second support claws, thereby ensuring stability during the spin welding process and preventing the column from misaligning.

[0021] Of course, since the base 11 and the column 12 have a relative position relationship, in order to be able to quickly position the base and the column, in this embodiment, a plurality of positioning columns 231 are provided on the rotating platform 23, and the mounting holes 111 on the base correspond to the positioning columns 231, and according to the structure of the base 11 and the column 12, the connection between the column 12 and the base 11 is adjusted as much as possible to be concentric with the rotation center of the rotating platform 23, so that the relative position of the welding gun and the connection can be guaranteed as much as possible, the gap change can be reduced, and the welding quality and positioning accuracy can be improved.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
