Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example

[0048] See also Figure 1-6 , the technical solution provided by this embodiment is as follows:

[0049] A metal welding device comprises a base 1, a workbench 2, a welding machine 5, a protective frame 6, a positioning cylinder 7, a clamping and correction mechanism and a rotating mechanism, wherein: the workbench 2 is fixedly connected to the top center of the base 1; the welding machine 5 is arranged on the upper side of the workbench 2; the protective frame 6 is fixedly connected to the top of the base 1, and two positioning cylinders 7 are arranged, which are respectively arranged on both sides of the workbench 2, and are rotatably connected in the protective frame 6; the clamping and correction mechanism is provided with two groups and is respectively arranged on the corresponding positioning cylinders 7, which are used to clamp and fix pipe fittings and correct the position; the rotating mechanism is arranged on the base 1, which is used to drive the two positioning cylinders 7 to rotate synchronously, so as to cooperate with the welding machine 5 for welding work.

[0050] In a specific embodiment of the present invention, the positioning cylinder 7 is used to install and fix the pipe fittings, which are distributed on both sides of the workbench 2 and can clamp two pipe fittings. The welding machine 5 is located between the two positioning cylinders 7 and is used to weld the two pipe fittings. The pressure roller 11 is used to contact the surface of the pipe fitting. When in use, the eccentric plate 14 is pushed to move by the extended end of the electric push rod 15, and the inclined rod 9 and the first pinion 10 fixed thereto are driven to deflect synchronously under the linkage of the linkage rod 13. Since the first pinion 10 is meshed with the first large gear 12, multiple first pinions 10 and the inclined rod 9 are deflected synchronously, and the deflection of the inclined rod 9 drives the pressure roller 11 to deflect, and multiple pressure rollers 11 are synchronously close to the pipe fitting, thereby clamping the pipe fitting. , fix the position of the pipe fitting, the two positioning cylinders 7 are based on the symmetrical structure of the workbench 2, and the center position is the same, so the center of the fixed pipe fitting is the same, which plays a role of automatic correction when fixing the pipe fitting, ensuring that the pipe fitting can be accurately welded without deviation, and the two positioning cylinders 7 can both rotate. During welding, the output end of the servo motor 20 is controlled to drive the linkage shaft 18 to rotate, and the linkage shaft 18 drives the two second small gears 19 to rotate synchronously. Under the action of meshing, the two second large gears 16 rotate synchronously, thereby driving the two positioning cylinders 7 to rotate synchronously, so that the two pipe fittings rotate synchronously, so as to cooperate with the 5360-degree circular welding work of the welding machine, automatic welding operation, and effectively improve work efficiency.

[0051] Specifically, each set of clamping and correction mechanisms includes:

[0052] Two first large gears 12 are provided and are both rotatably connected to the circumferential surface of the positioning cylinder 7;

[0055] A linkage rod 13, which is fixedly connected to the other end of the eccentric plate 14, and whose two ends extend toward the first large gear 12; and

[0056] The eccentric clamping assembly is provided with multiple groups, which move synchronously through the eccentric structure to clamp the pipe fittings. Each group of eccentric clamping assemblies includes a miniature bearing seat 8, an inclined rod 9, a first pinion 10 and a pressure roller 11. The miniature bearing seat 8 is fixedly connected to the circumferential surface of the positioning cylinder 7, one end of the inclined rod 9 is rotatably connected to the miniature bearing seat 8, and the other end of the inclined rod 9 extends into the positioning cylinder 7. The first pinion 10 is fixedly connected to one end of the inclined rod 9, and the pressure roller 11 is fixedly connected to the other end of the inclined rod 9. The first pinion 10 is meshed with the first large gear 12.

[0057] In a specific embodiment of the present invention, the inclined rod 9 and the first small gear 10 are evenly distributed around the positioning cylinder 7, and the linkage rod 13 is fixedly connected between the two inclined rods 9 located at the same center of the circle. The linkage rod 13 is used to link the two first large gears 12. The extended end of the electric push rod 15 can push the eccentric plate 14 to deflect, and the eccentric plate 14 drives the linkage rod 13 to rotate slightly. The linkage rod 13 drives the inclined rod 9 and the first small gear 10 fixed thereto to rotate. Since the first large gear 12 is meshed with multiple first small gears 10, one of the first small gears 10 rotates. Under the action of the first large gear 12, it can drive the remaining first small gears 10 to rotate synchronously, and then drive the inclined rod 9 and the pressure roller 11 to deflect synchronously. When the pressure roller 11 approaches synchronously, the pipe fitting can be clamped, and when the pressure roller 11 moves away synchronously, the pipe fitting can be loosened.

The servo motor 20 is used to drive the linkage shaft 18 to rotate, so as to drive the two second small gears 19 to rotate synchronously, and then drive the two second large gears 16 meshing therewith to rotate synchronously. The second large gear 16 is fixed to the positioning cylinder 7, so that the two positioning cylinders 7 rotate synchronously, and can drive the two clamped pipe fittings to rotate synchronously to cooperate with the welding work of the welding machine 5.

[0061] In a specific embodiment of the present invention, the linear motor 3 is a linear motor commonly used in industry, which directly converts electrical energy into linear motion mechanical energy without the need for any intermediate conversion mechanism transmission device. Two linear motors 3 are provided, close to both sides of the workbench 2. When working, the linear motor 3 can control the linear movement of the support frame 4, and then control the linear movement of the welding machine 5, adjust the position of the welding machine 5 to match the welding position of the pipe fitting, and expand the scope of application.

[0062] Specifically, two protection frames 6 are respectively provided on both sides of the workbench 2 , and the positioning cylinder 7 is rotatably connected between the two protection frames 6 .

[0063] In a specific embodiment of the present invention, each positioning cylinder 7 corresponds to two protection frames 6 , which can stably support the rotation of the positioning cylinder 7 .

[0066] S2, control the extended end of the electric push rod 15 to push the eccentric plate 14 to move, and the eccentric plate 14 drives the linkage rod 13 to rotate slightly, thereby driving the inclined rods 9 and the first pinion 10 fixed thereto on both sides to rotate synchronously. Under the action of meshing, the two first large gears 12 rotate synchronously, and then drive the multiple first pinion gears 10 to rotate synchronously with a small amplitude, so that the multiple inclined rods 9 are synchronously close to the pipe fittings, and finally the multiple pressure rollers 11 clamp the pipe fittings to fix the position of the pipe fittings;

[0067] S3, placing the second pipe fitting in another positioning tube 7, and adjusting the distance between the second pipe fitting and the first pipe fitting, and then repeating step S2 to fix the position of the second pipe fitting;
