[0043] Referring to Figure 1The lower part of the base plate 1 is provided with a directional wheel 8 and a brake universal wheel 9, which facilitates the movement of the harvester toothed roller welding fixture.

[0044] When welding the toothed rollers using the harvester toothed roller welding fixture provided by this invention, the following steps are followed: First, operate the pneumatic mechanism 7 to loosen all clamping parts; as... Figure 8 As shown, the roller shaft 10 is sequentially passed through the center holes of the four flanges (i.e., rear flange 11, middle flange 13, rear flange 2 12, and middle flange 2 14), and two flat keys are placed in the keyways of the middle flange 13 and the middle flange 2 14 respectively to fix the rotation position and prevent rotation between the roller shaft 10 and the flanges; then the assembly of the roller shaft 10 and the flanges is placed on the welding fixture, as shown. Figure 9 As shown, the first end 15 of the roller shaft 10 is supported by the positioning parts 23 and 24 of the first roller shaft positioning and clamping mechanism 2, and the second end 16 of the roller shaft 10 is supported by the positioning parts 1 and 2 of the second roller shaft positioning and clamping mechanism 3. The end faces of the first end 15 and the second end 16 are positioned by two positioning parts 27 respectively. The bottom circumferential positioning of the four discs is achieved by the positioning seats 2 51 of the four first disc positioning and clamping mechanisms 5 and the positioning seats 3 61 of the four second disc positioning and clamping mechanisms 6. Then, three reinforcing tubes 17 are inserted into the corresponding through holes of the four discs (i.e., rear disc 11, middle disc 13, rear disc 2 12, and middle disc 2 14) in sequence, and the two ends of the three reinforcing tubes 17 are flush with the two outer end faces of the rear disc 11 and the middle disc 2 14 respectively. Then, the four positioning pins 55 of the four first disc positioning and clamping mechanisms 5 are inserted into the four discs respectively. The four discs are positioned within the corresponding pin holes. The pneumatic mechanism 7 is operated, causing the clamping cylinder 22 of the first roller shaft positioning and clamping mechanism 2 to move the positioning element 26 closer to and clamp the first end 15 of the roller shaft 10, and the positioning element 3 of the second roller shaft positioning and clamping mechanism 3 to move closer to and clamp the second end 16 of the roller shaft 10, thus completing the positioning and clamping of the roller shaft 10. The pneumatic mechanism 7 is then operated again, causing the clamping cylinder 52 of the first disc positioning and clamping mechanism 5 to move the positioning element 54 closer to and clamp the first position of the disc, and the clamping cylinder 62 of the second disc positioning and clamping mechanism 6 to move the positioning element 64 closer to and clamp the second position of the disc, thus completing the positioning and clamping of the four discs. At this point, the positioning and clamping of all welded components are complete. Then, each weld seam is welded. After welding, the pneumatic mechanism 7 is operated to release all clamping elements and remove the positioning pins 55 of the four first disc positioning and clamping mechanisms 5. The welded toothed roller assembly is then lifted out of the fixture using a lifting device.
