A flux conveying component 3 is also provided on one side of the welding gun seat 1, and the flux conveying component 3 also adopts a plate-like structure. A wire row is provided between the welding gun seat and the deflection welding gun to achieve conduction.

[0026] The welding gun seat 1 is a plate-like structure made of conductive material, and a deflection welding gun mounting groove is provided at the bottom thereof.

Preferably, the wire row adopts a copper row 5 composed of soft copper wire, one end of the copper row 5 is fixed to the welding gun seat 1 by a screw, and the other end is fixed to the top of the deflection welding gun.

[0028] A conductive tube 2 is fixed to one side of the top of the welding gun seat 1, and the conductive tube 2 is used to connect to the welding power source. Specifically, a U-shaped clamping plate is provided at the bottom end of the conductive tube 2, and the U-shaped clamping plate is clamped on the top of the welding gun seat 1 and fixed to the welding gun seat by bolts.

[0029] The conductive tube 2, the welding gun seat 1 and the deflection welding gun are all provided with a welding wire channel 6, and the welding wire channel 6 is used for the welding wire to pass through.

[0030] Preferably, the conductive tube 2 and the welding wire channel 6 of the welding gun holder 1 are coaxially arranged.

[0031] The top end of the conductive tube 2 is provided with an external thread structure, which can be connected to the welding wire feeding tube, so as to receive the welding wire fed by the wire feeding tube.

[0032] The deflection welding gun includes a deflection frame 7, the top of the deflection frame 7 is located in the deflection welding gun installation groove, and a rotating shaft 4 is arranged on both sides thereof. The deflection frame 7 is rotatably connected to the welding gun seat 1 through the rotating shaft 4, and the axis of the rotating shaft 4 is perpendicular to the axis of the conductive tube 2, and the plane where the axis of the rotating shaft 4 and the axis of the conductive tube 2 are located is parallel to the plate surface of the welding gun seat 1.

[0033] The deflection frame 7 also adopts a plate-shaped structure, and its thickness is the same as that of the welding gun seat 1 .

[0034] A clamping assembly is provided at the bottom of the deflection frame 7, and the clamping assembly is used to clamp and fix the welding wire.

[0035] The clamping assembly includes a fixed part 8 and a movable part 9, and the fixed part 8 and the movable part 9 are used to clamp and fix the welding wire. Accordingly, the deflection frame 7 is provided with a welding wire channel 6 that runs through its top and bottom surfaces, and the position of the welding wire channel 6 corresponds to the position between the fixed part 8 and the movable part 9.

[0036] The material of the fixed part 8 and the deflection frame 7 are different from each other and are welded together. The top of the fixed part 8 is welded and fixed to the bottom of the deflection frame 7. The resistance of the material of the fixed part 8 is much greater than that of the deflection frame 7. For example, the fixed part 8 is made of cast iron. During the welding process, when the movable part 9 is adjusted, the welding current is prevented from breaking through and damaging the fixed part 8.

[0037] The fixed portion 8 is fixedly connected to the deflection frame 7 , and the top end of the movable portion 9 is slidably connected to the deflection frame 7 so that the movable portion 9 can move toward or away from the fixed portion 8 .

[0038] In this embodiment, the thickness of the fixed portion 8 and the movable portion 9 is the same as that of the deflection frame 7. The sides of the fixed portion 8 and the movable portion 9 for clamping the welding wire are provided with clamping blocks 10, and the facing sides of the two clamping blocks 10 are provided with arc grooves matching the welding wire.

[0039] Furthermore, the deflection frame 7 is provided with a slide rail 11 , and correspondingly, the top of the moving part 9 is provided with a slide groove matching the slide rail 11 , and the slide rail 11 cooperates with the slide groove to achieve a sliding connection between the moving part 9 and the deflection frame 7 .

[0040] Preferably, the slide rail 11 is a T-shaped slide rail, and correspondingly, the slide groove is a T-shaped groove.

[0041] The moving part 9 is connected to a moving driving component installed on the deflection frame, and the moving driving component is used to drive the moving part 9 to move toward or away from the fixed part.

[0042] The mobile driving component includes at least one guide rod 12. In the present embodiment, two guide rods 12 are provided. The axes of the two guide rods 12 are arranged along the movement direction of the moving part 9. The guide rod 12 passes through the moving part 9 and is fixedly connected to the deflection frame 7. The moving part 9 is slidably connected to the guide rod 12. One end of the guide rod 12 is fixed to the deflection frame 7, and the other end is provided with an external thread structure and is threadedly connected with two nuts 13. An elastic member is provided between the inner nut 13 and the outer side surface of the moving part 9. Preferably, the elastic member adopts a disc spring 14 which is sleeved on the outer periphery of the guide rod 12.

[0043] When it is necessary to clamp the welding wire, the elastic force of the disc spring 14 is overcome and the movable part 9 is pulled outward. At this time, the distance between the movable part 9 and the fixed part 8 increases, and the welding wire is passed through the space between the two clamping blocks 10. Then the movable part 9 is released. Under the elastic force of the disc spring 14, the movable part 9 moves toward the fixed part 8 and clamps the fixed welding wire.

[0044] By rotating the two nuts 13, the two nuts 13 can move along the axis direction of the guide rod 12, so as to adjust the clamping force. By providing the nuts 13 and the disc spring 14, the clamping requirements of welding wires with different diameters are met.

[0045] The deflection drive assembly includes a support seat 15, which is fixed to the top of the welding gun seat 1, and the support seat 15 is fixed to a transmission box 16 located on one side of the top of the welding gun seat 1, thereby achieving the fixing of the transmission box 16 on one side of the top of the welding gun seat 1.

[0046] In this embodiment, the support seat 15 is made of insulating material and includes a U-shaped portion, which is clamped on the top edge of the welding gun seat 1 and fixedly connected to the welding gun seat 1 by bolts. A support plate is provided on one side of the U-shaped portion, and a transmission box 16 is fixed to the support plate.

[0047] The transmission box 16 includes a box body, which is fixed on a support plate. A side wall of the box body is connected to an input shaft through a bearing. The input shaft is connected to the output shaft through a bevel gear transmission mechanism. A handle 17 is provided on the part of the input shaft located outside the box body to facilitate the staff to rotate the input shaft. The output shaft is rotatably connected to the top box wall of the box body through a bearing. A first gear 18 located above the box body is installed on the output shaft. The output shaft can drive the first gear 18 to rotate. The first gear 18 is meshed with the second gear 19. The second gear 19 is fixedly connected to the top end of a lever 20. The lever 20 is arranged parallel to the axis of the conductive tube 2. After the lever 20 passes through the support seat 15 and the welding gun seat 1, a rotating rod 21 perpendicular to it is arranged at its bottom.

[0048] The lever 20 is rotatably connected to the support seat 15 and the welding gun seat 1 and an insulating layer is arranged between the lever 20 and the welding gun seat 1. The rotating rod 21 is made of insulating material. The rotating rod 21 passes through the through hole set in the lever 20 and the rotating rod 21 is slidably connected with the lever 20 so that the rotating rod 21 can move along its own axial direction.

[0049] A ball head is provided at one end of the rotating rod 21, and the ball head is embedded in the vertical long groove 22 provided in the deflection frame 7. The long axis of the vertical long groove 22 is parallel to the axis of the conductive tube 2 and the lever 20, and the groove surface of the vertical long groove 22 adopts an arc surface matching the ball head.

[0050] The lever 20 rotates around its own axis and can drive the rotating rod 21 to rotate at the same time. Under the cooperation of the ball head and the vertical long groove 22, the rotating rod 21 rotates and moves linearly along its own axis at the same time. The ball head is used to drive the deflection frame 7 to rotate, thereby realizing the swing of the deflection welding gun, and then the welding wire can be welded in multiple layers and multiple passes.

[0051] A flux conveying component 3 is provided on one side of the welding gun seat 1. The flux conveying component adopts a plate-like structure, and two connecting plates 23 are provided on one side. The connecting plates 23 are respectively located on both sides of the welding gun seat 1. The two connecting plates 23 are fixed to the welding gun seat 1 by bolts, and an insulating plate is provided between the connecting plates 23 and the welding gun seat.

[0052] The flux conveying component 3 adopts a hollow structure, with a flux input tube at the top and a flux output tube at the bottom. The discharge end of the flux output tube is arranged toward the bottom of the deflection welding gun, that is, toward the bottom end of the clamping assembly, for providing flux for welding and conveying the flux to the part to be welded.

[0053] The welding gun structure of this embodiment is as follows: Figure 4 As shown, after the conductive tube 2 is connected to the welding power supply, the welding electricity required for welding is conducted from the conductive tube 2 to the welding gun holder 1, and then transmitted to the deflection welding gun through the copper bus 5. The clamping assembly clamps the welding wire, and the bottom of the deflection welding gun is extended into the bottom welding position between the horizontal workpiece 24 to be welded and the side plate workpiece 25 to be welded. The welder holds the deflection drive assembly to drive the deflection welding gun to move, and completes the welding operation.

[0054] Since the welding gun seat and the deflection welding gun both adopt a plate-like structure, and the deflection drive assembly is arranged on one side of the top of the welding gun seat, when the height of the vertical panel is high and the distance between the weld to be welded and the vertical panel is narrow, since the deflection drive assembly is arranged on one side of the welding gun seat, the other side of the welding gun seat and the deflection welding gun can be as close as possible to the welding wall of the workpiece to be welded of the vertical panel, so that the deflection welding gun can extend to the bottom of the part to be welded, meeting the welding requirements when the side vertical panel is high and the distance between the weld to be welded and the side vertical panel is narrow.

[0055] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
