The upper ends of the first welding positioning seat 7 and the second welding positioning seat 8 are provided with a welding gun position adjustment component 9. The welding gun 10 is fixed on the welding gun position adjustment component 9.

[0029] In this embodiment, the welding seat translation assembly uses a lead screw assembly. Lead screw assemblies are mature existing technology, and this application will not provide a detailed structural description of the lead screw assembly.

[0030] The first welding positioning seat 7 is slidably disposed on the first welding seat 5, and the second welding positioning seat 8 is slidably disposed on the second welding seat 6. The first welding seat 5 is provided with a positioning seat translation cylinder 11 for pushing the first welding positioning seat 7 to slide, and the second welding seat 6 is also provided with a positioning seat translation cylinder 11 for pushing the second welding positioning seat 8 to slide.

[0031] Two sets of roller support roller assemblies 12 are provided on the welding frame 1 between the first welding seat 5 and the second welding seat 6. The roller support roller assembly 12 is connected to a rotation power assembly, thereby driving the roller to rotate and realize the welding of the shaft head. Each set of roller support roller assembly 12 is provided with a roller pressure roller 13 on its upper side.

[0032] One set of roller idler assembly 12 has an idler lifting seat 22 mounted on a fixed mounting base, while the other set of roller idler assembly 12 has an idler lifting seat 22 mounted on a second welding base 6. A column 15 is provided on one side of the idler lifting seat 22, and a pressure roller lifting cylinder 16 is provided at the upper end of the column 15.

The upper roller support rods 3 and the first roller support plate 20 are both inclined upwards in the direction away from the welding frame 1, while the second roller support plate 21 and the lower roller support rods 4 are inclined downwards in the direction away from the welding frame 1. The first roller support plate 20 is connected to a roller support plate lifting assembly, and the second roller support plate 21 is fixedly installed. Specifically, in this embodiment, the roller support plate lifting assembly is a support plate lifting cylinder 23.

[0039] See Figure 7 The roller idler assembly 12 includes a first roller idler 30 and a second roller idler 31 arranged in parallel. The rotational power assembly includes a rotary motor 24, a chain 25, a drive sprocket 26, a first driven sprocket 27, a second driven sprocket 28, and a tension sprocket 29. The drive sprocket 26 is connected to the rotary motor 24. The chain 25 connects the drive sprocket 26, the first driven sprocket 27, the second driven sprocket 28, and the tension sprocket 29. The first driven sprocket 27 and the second driven sprocket 28 are respectively connected to the first roller idler 30 and the second roller idler 31. The tension sprocket 29 is disposed between the first driven sprocket 27 and the second driven sprocket 28.

[0040] See Figure 8 In this embodiment, the welding torch position adjustment assembly 9 includes a first horizontal lead screw adjustment seat 35, a second horizontal lead screw adjustment seat 36, a vertical lead screw adjustment seat 37, and a welding torch feed cylinder 38. The first horizontal lead screw adjustment seat 35 is fixed to the upper end of the first welding positioning seat 7 or the second welding positioning seat 8. The vertical lead screw adjustment seat 37 is disposed on the upper side of the first horizontal lead screw adjustment seat 35, and the second horizontal lead screw adjustment seat 36 is disposed on the vertical lead screw adjustment seat 37. The first horizontal lead screw adjustment seat 35 and the second horizontal lead screw adjustment seat 36 are perpendicular to each other. The welding torch feed cylinder 38 is disposed on the second horizontal lead screw adjustment seat 36 through a bracket. The position of the welding torch 10 is adjusted by the first horizontal lead screw adjustment seat 35, the second horizontal lead screw adjustment seat 36, and the vertical lead screw adjustment seat 37. During welding, the welding torch feed cylinder 38 pushes the welding torch 10 to the welding position.

[0041] Working process: The support translation screw assembly 18 drives the roller support 14 to move towards the roller storage rack 2. The pallet lifting cylinder 23 drives the first roller support 20 to rise, making the roller higher than the roller stop block 32. The roller rolls along the first roller support 20 towards the welding frame 1 and rolls into the groove of the roller support 14. Then, the support translation screw assembly 18 drives the roller support 14 to move towards the welding frame 1. Finally, the support lifting screw assembly 19 drives the roller support 14 to descend and place the roller on the roller support assembly 12.

[0042] The positioning seat translation cylinder 11 pushes the first welding positioning seat 7 and the second welding positioning seat 8 to slide, the first welding positioning column 33 and the second welding positioning column 34 axially position the two ends of the roller shaft to be welded, and the pressure roller lifting cylinder 16 drives the roller shaft pressure roller 13 to descend and press it on the roller shaft.

[0043] The welding torch feed cylinder 38 pushes the welding torch 10 to the welding position. The rotary motor 24 drives the first roller shaft support roller 30 and the second roller shaft support roller 31 to rotate via the chain 25 and each sprocket, thereby driving the roller shaft to rotate. The welding torch 10 then welds the shaft head. After welding is completed, the pressure roller lifting cylinder 16 drives the roller shaft pressure roller 13 to rise. At the same time, the positioning seat translation cylinder 11 drives the first welding positioning seat 7 and the second welding positioning seat 8 to retract. The welding torch feed cylinder 38 drives the welding torch 10 back to its original position.

[0044] The support lifting screw assembly 19 drives the roller support 14 to rise, lifting the roller on the roller support assembly 12. Then the support translation screw assembly 18 drives the roller support 14 to move towards the roller storage rack 2. The support lifting screw assembly 19 drives the roller support 14 to fall, and the rollers roll along the second roller support plate 21 onto the roller stud, and continue to roll on the second roller support plate 21 to be arranged one by one.
