[0001] The invention relates to the technical field of welding equipment, in particular to a welding device with a fixed structure. Background Art

[0002] There are many types of welding devices, the most common ones are arc welding equipment, gas shielded welding equipment and laser welding equipment. Arc welding uses the heat of the arc to locally melt the weldment and cool it to solidify. Gas shielded welding equipment uses gas protection to reduce the chemical reaction between the electron beam and the metal, thereby reducing the oxidation reaction, thereby achieving welding. Laser welding equipment uses a high-energy-density laser beam to locally melt the weldment and cool it to solidify, thereby achieving welding.

[0003] Welding is a common process in industrial production and is widely used in many fields. The welding device is a key equipment for the welding process. When welding metal products, the metal parts need to be fixed to prevent the two sets of metal from being misaligned during the welding process. When welding some tubular metal parts, the welding joint needs to be welded around a circle. After the fixing structure on the welding device in the prior art fixes the metal part, the metal part will be unable to move. Therefore, after welding a part of the metal part, it is necessary to release the fixation of the metal part and then adjust the position of the weld, which affects the efficiency of welding the metal parts.

[0013] As a preferred solution of the present invention, the bottom end of the support plate is provided with a chamfer, and when the support plate moves downward, the top surface of the extrusion plate can block the support plate.

[0014] As a preferred solution of the present invention, the top of the support plate passes through the workbench and extends above the workbench.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] like Figure 1-7 As shown, the present invention provides a technical solution of a welding device with a fixed structure: a welding device with a fixed structure, comprising a workbench 1, a support frame 2 is installed on the top of the workbench 1, a laser welding head 3 is arranged on the top of the support frame 2, and further comprising:

[0031] An adjustable fixing structure, which is arranged on the workbench 1 and is used to freely control the welding position of the metal part;

[0032] Among them, the adjustable fixing structure includes two groups of fixed brackets 4, and the two groups of fixed brackets 4 are respectively fixed on both sides of the top of the workbench 1. The fixed brackets 4 are rotatably connected to the first rotating shaft 5. A boss member 6 is fixed to one end of the first rotating shaft 5. Both sides of the boss member 6 are hinged with clamping claws 7. A movable rod 8 is sleeved on the middle part of the first rotating shaft 5. One end of the movable rod 8 passes through the boss member 6 and is fixed with a first connecting frame 9. The other end of the movable rod 8 passes through the first rotating shaft 5 and is equipped with a second connecting frame 16 in cooperation with the bearing 15. Both sides of the first connecting frame 9 are hinged with rotating frames 10. One end of the clamping claw 7 is fixed with a clamping member 11. A first gear 12 is fixed to the outer surface of the rotating shaft 5, a synchronous motor 13 is fixed to one side of the fixed bracket 4, a second gear 14 is fixed to the output shaft of the synchronous motor 13, a connecting plate 17 is fixed to the bottom end of the second connecting frame 16, a first cavity 18 is opened in the inner cavity of the workbench 1, a driving motor 19 is fixed inside the workbench 1, a second rotating shaft 20 is fixed to the output shaft of the driving motor 19, a movable plate 21 is slidably connected inside the first cavity 18, an extrusion plate 22 is fixed to the top of the movable plate 21, a connecting shaft 23 is fixed to one side of the extrusion plate 22, and a first spring 24 is sleeved on the outer surface of the connecting shaft 23.

[0033] By the operation of the driving motor 19, the two sets of movable plates 21 can be driven to move toward or away from each other along the inner side of the first cavity 18 through the second rotating shaft 20, so that the extrusion plate 22 can be driven to move through the movable plate 21, and at the same time, through the cooperation between the connecting shaft 23 and the connecting plate 17, the connecting shaft 23 is driven to move along the inner side of the connecting plate 17. At this time, due to the elastic force of the first spring 24, the connecting plate 17 will be supported, so that the second connecting frame 16 can be driven by the connecting plate 17 to pull the movable rod 8 to move, and at the same time, through the cooperation between the movable rod 8 and the first rotating shaft 5, the first connecting frame 9 can be driven to move. At this time, through the first connecting frame 9 and the rotating frame 10 The cooperation between them can pull the clamping jaws 7 to rotate along both sides of the boss part 6, so as to drive the clamping part 11 to clamp the metal part. After clamping the metal part, due to the elastic force of the first spring 24, it can play a buffering role to avoid excessive squeezing of the metal part and prevent it from deformation. Through the operation of the synchronous motor 13, the second gear 14 will rotate. At the same time, through the cooperation between the second gear 14 and the first gear 12, the first rotating shaft 5, the boss part 6 and the clamping jaw 7 can be driven to rotate, and then the rotation of the metal part can be controlled when the metal part is fixed. Therefore, the laser welding head 3 can be used to weld a circle of the welding port of the metal part.

[0034] like Figure 5 , 6 As shown, a second cavity 25 is provided inside the workbench 1 , a fixed shaft 26 is installed inside the second cavity 25 , and a second spring 27 and a support plate 28 are sleeved on the outer surface of the fixed shaft 26 .

[0035] Through the design of the support plate 28, the metal parts can be supported, which is convenient for placing the metal parts and making the welding joints contact. The metal parts are then fixed using an adjustable fixing structure. During the process of fixing the metal parts, the movement of the extrusion plate 22 will drive the extrusion plate 22 to separate from the support plate 28. At this time, the elastic force of the second spring 27 will drive the support plate 28 to move toward each other along the outer surface of the fixed shaft 26, thereby driving the support plate 28 to shrink and preventing the support plate 28 from blocking the rotating metal parts.

[0036] like Figure 2 As shown, the first gear 12 is embedded in the inner side of the fixing bracket 4 , and the second gear 14 is meshedly connected with the first gear 12 .

[0037] Through the design of the first gear 12, the left and right movement of the first rotating shaft 5 can be restricted. At the same time, through the cooperation between the second gear 14 and the first gear 12, when the second gear 14 rotates, it will drive the first gear 12 to rotate. Therefore, the first rotating shaft 5 can be driven to rotate through the cooperation between the first gear 12 and the first rotating shaft 5. Therefore, the boss part 6 and the clamping jaw 7 will be driven to rotate through the first rotating shaft 5, which is convenient for controlling the rotation of the metal part and adjusting the position of its welding interface.

[0038] like Figure 2 As shown, the end of the rotating frame 10 is hinged to the clamping claw 7, the outer surface of the clamping member 11 is corrugated, and the clamping member 11 is made of rubber, and the clamping member 11 is in extrusion contact with the metal member.

[0039] Through the cooperation between the rotating frame 10 and the first connecting frame 9 and the rotating frame 10 and the clamping jaw 7, when the first connecting frame 9 moves, the rotating frame 10 will drive the clamping jaw 7 to rotate, so that the clamping member 11 will be driven by the clamping jaw 7 to squeeze the metal part so that it is clamped and fixed with the metal part.

[0040] like Figure 4 As shown, the outer surface of the second rotating shaft 20 is provided with two sections of threads, the two sections of threads are in opposite directions and are respectively located at two ends of the second rotating shaft 20 , and the second rotating shaft 20 is threadedly connected to the movable plate 21 .

[0041] Through the design of the second rotating shaft 20, due to the two opposite threads set on the outer surface of the second rotating shaft 20, and the cooperation between the second rotating shaft 20 and the movable plate 21, the two groups of movable plates 21 can be driven to move toward or away from each other along the inner side of the first cavity 18, and finally the clamping jaws 7 can be controlled to expand or merge, so as to facilitate the control of fixing or loosening the metal parts.

[0042] like Figure 4 , 5As shown, the end of the extrusion plate 22 is bent downward, the first spring 24 is elastically supported between the extrusion plate 22 and the connecting plate 17 , and the bending part of the extrusion plate 22 is in extrusion contact with the chamfered part of the support plate 28 .

[0043] Through the design of the first spring 24, an elastic force will be applied to the connecting plate 17. When the extrusion plate 22 moves, a pressure will be applied to the connecting plate 17 through the first spring 24, so that the movable rod 8 can be driven to move through the second connecting frame 16. When the connecting plate 17 cannot continue to move, the first spring 24 will be compressed to increase the pressure applied to the second connecting frame 16, while preventing deformation of metal parts caused by excessive pressure.

[0044] like Figure 4 As shown, the bottom end of the support plate 28 is provided with a chamfer, and when the support plate 28 moves downward, the top surface of the extrusion plate 22 can block the support plate 28.

[0045] By setting the chamfer at the bottom end of the support plate 28, when the extrusion plate 22 is reset, its bent portion will squeeze the inclined surface of the chamfer of the support plate 28, thereby driving the support plate 28 to move upward along the outer surface of the fixed shaft 26, so that it extends to the top of the workbench 1 to support the metal parts.

[0046] like Figure 4 , 6 As shown, the top of the support plate 28 passes through the workbench 1 and extends above the workbench 1. When the support plate 28 moves upward, it can support the metal part. The second spring 27 is elastically supported between the top of the inner cavity of the second cavity 25 and the support plate 28.

[0047] Through the design of the second spring 27, the support plate 28 has good elastic reset performance. At this time, since the second spring 27 is in a compressed state, it will apply an elastic force to the support plate 28, so that when the extrusion plate 22 is separated from the support plate 28, it can drive the support plate 28 to move downward.

[0048] like Figure 4 As shown, when the extrusion plate 22 is separated from the support plate 28 , the top of the support plate 28 can be separated from the top of the workbench 1 .

[0049] Through the cooperation between the support plate 28 and the fixed shaft 26, when the extrusion plate 22 releases the obstruction of the support plate 28, the support plate 28 will move downward along the outer surface of the fixed shaft 26. At this time, the support plate 28 will be disengaged from the top of the workbench 1, and thus will be separated from the metal parts, preventing the metal parts from being interfered with by the support plate 28 during rotation.

[0050] Working principle:

[0051] First, place the two sets of metal parts on the top of the support plate 28 and connect the welding ports. Then, start the driving motor 19 to drive the two sets of movable plates 21 to move toward or away from each other along the inner side of the first cavity 18 through the second rotating shaft 20, so that the extrusion plate 22 can be driven to move through the movable plate 21. At the same time, through the cooperation between the connecting shaft 23 and the connecting plate 17, the connecting shaft 23 is driven to move along the inner side of the connecting plate 17. At this time, the elastic force of the first spring 24 will push the connecting plate 17 and drive the second connecting frame 16 to pull the movable rod 8 to move. At the same time, through the movable rod 8 and the first rotating shaft 5 The cooperation between them can drive the first connecting frame 9 to move. At this time, through the cooperation between the first connecting frame 9 and the rotating frame 10, the clamping jaws 7 can be pulled to rotate along both sides of the boss part 6, so as to drive the clamping member 11 to clamp the metal part. After the metal part is clamped, and through the operation of the synchronous motor 13, the second gear 14 will rotate. At the same time, through the cooperation between the second gear 14 and the first gear 12, the first rotating shaft 5, the boss part 6 and the clamping jaws 7 can be driven to rotate. Finally, through the operation of the laser welding head 3, the welding joint between the metal parts is welded around one circle.

[0052] 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.
