[0002] A welding positioner is an auxiliary device used in the welding process. Its main function is to move the workpiece to be welded so that the weld seam on the workpiece can be moved to the most suitable position for welding. By rotating or flipping the workpiece, this device can make previously difficult or unfavorable welding positions easier to access, thereby improving welding quality and efficiency.

A driving device is provided inside the first support base, and the driving device includes a slide rail, a slide bar and a driven gear block. The slide bar is provided with a plurality of protrusions on the side facing away from the slide rail. The driven gear block is provided at one end of the tilting bracket extending from the rotating bearing, and the driven gear block is meshed with the plurality of protrusions. The end of the slide bar is fixedly connected to a telescopic cylinder, and a gas-controlled switch is also provided on one side of the first support base, and the gas-controlled switch is connected to and controls the telescopic cylinder.

[0005] When using a welding positioner to weld workpieces, the workpieces vary in size, while the size of the rotating worktable of the welding positioner is fixed. When fixing the workpiece to the worktable, bolts are usually passed through the holes on the workpiece and the worktable and then tightened with nuts. However, the fixing holes of some larger workpieces may not be exactly aligned with the holes on the worktable. Similarly, some smaller workpieces may not be exactly installed on the two support frames of the worktable, resulting in unstable support and great inconvenience. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 5 A welding positioner with an adjustment mechanism includes a base 1, two support columns 2 installed on the base 1 and a rotating table 3 installed between the two support columns 2. The upper surfaces of two cross bars of the rotating table 3 are penetrated by upper sliding openings 301, and the sides of the two upper sliding openings 301 away from each other are penetrated by side sliding openings 302. The inner walls of the two upper sliding openings 301 are connected to a plurality of sliding components. The plurality of sliding components are grouped in pairs. The sides of the two sliding components in the same group away from the upper sliding openings 301 are penetrated by the side sliding openings 302 to the outside of the side sliding openings 302, and are connected with extension components at the same time.

[0024] The welding positioner with an adjustment mechanism in the present invention is similar in structure to the existing welding positioner with an adjustment mechanism, such as the welding positioner disclosed in patent publication number CN208840799U. Figures 1 to 5 As shown, when the welding positioner with an adjustment mechanism in the present invention is in use, the sliding assembly can be manually pushed according to the size of different workpieces, and the sliding assembly can be laterally displaced in the upper sliding opening 301. While the sliding assembly is displaced, the extension assembly can be moved through one end of the side sliding opening 302, so that the extension assembly can change the support space of the entire rotating table 3, and thus different workpieces can be installed and fixed more accurately and reasonably, ensuring stability during welding.

[0025] like Figure 1-Figure 5 As shown, the sliding assembly includes a slide bar 7 and a connecting rod 8, the outer wall of the slide bar 7 is slidably connected to the inner wall of the upper sliding opening 301, a side in the middle part of the slide bar 7 is fixedly connected to one end of the connecting rod 8, and the other end of the connecting rod 8 runs through the side sliding opening 302 to the outside of the side sliding opening 302, and is connected to one end of the extension assembly. The upper end of the slide bar 7 is fixedly connected with an anti-drop block 6, the outer wall of the anti-drop block 6 is against the side wall of the rotating table 3, and the anti-drop block 6 is penetrated to the below of the slide bar 7 by a bolt and is tightened and fixed by a nut. The upper surface of the upper sliding opening 301 offers a flush opening 303, the outer wall of the anti-drop block 6 is slidably connected to the inner wall of the flush opening 303, the upper surface of the anti-drop block 6 offers a connecting port 601, and the bolt connected with the anti-drop block 6 and the slide bar 7 is located in the connecting port 601.

[0026] More specifically, when the extension assembly needs to be moved, it is only necessary to first loosen the nut located under the slide rod 7 to reduce the friction between the bolt located in the connecting port 601 and the upper slide port 301, and then manually push the slide rod 7 and the connecting rod 8 along one side of the upper slide port 301, and then the position of the extension assembly between the upper slide port 301, the side slide port 302 and the flush port 303 can be changed through the connecting rod 8.

[0027] It should be noted that the flush opening 303 and the connection opening 601 are provided to maintain the flushness of the upper surface of the rotary table 3 to avoid affecting the subsequent installation of the mold.

[0028] like Figure 1-Figure 5As shown, the extension assembly includes a connecting plate 5 and two extension plates 4. The upper surfaces of the two extension plates 4 are each provided with a plurality of connection holes 401. One end of each extension plate 4 is fixedly connected to one end of each connecting rod 8 extending through the side sliding opening 302. The other end of each extension plate 4 defines a rotation cavity 402. The ends of the connecting plate 5 are located within the two rotation cavities 402, and the outer wall of the connecting plate 5 is slidably connected to the inner wall of the rotation cavity 402. Rotating rods 9 are fixedly connected to the upper and lower sides of both ends of the connecting plate 5. The two rotating rods 9 at the same end of the connecting plate 5 are rotatably connected to the inner walls of the two rotation cavities 402 of the same extension plate 4. The connecting plate 5 and the two extension plates 4 are connected to the bottom of the extension plates 4 by two bolts extending through the four rotating rods 9 and tightened with nuts. The upper surfaces of the two rotating rods 9 at the upper end of the connecting plate 5 each define a clamping opening 901, and the two bolts connecting the rotating rods 9 are located within the two clamping openings 901.

[0029] More specifically, when the connecting rod 8 is displaced, the extension plate 4 will move together with it. While the extension plate 4 is moving, the two adjacent extension plates 4 will rotate through the four rotating rods 9 and the two sliding rods 7 on the connecting plate 5, thereby maintaining the relative rotation between the two extension plates 4 while ensuring that they are not separated from each other. After the position between the two extension plates 4 is determined, the connecting plate 5 and the two extension plates 4 are fixed by two bolts.

[0030] It should be noted here that: by setting the connection hole 401, when fixing the mold, it can cooperate with the mounting hole on the mold and be fixed by bolts; and by setting the clamp 901, the flushness of the upper surface of the extension plate 4 can be maintained to avoid affecting the subsequent installation of the mold.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
