[0060] like Figure 1 As shown, the embodiment of the present application provides a small feeding wheel welding tooling structure of a silage machine, including: a base plate 1, two roller support plate devices 2, a main positioning clamping device 3, four inner arc surface positioning devices 4, an intermediate cylinder positioning clamping device 5, four spiral clamping devices 6, six clamping devices 7, a flip assembly 8, two connecting seats 9, a cylinder body welding rotation positioning device 10, two intermediate cylinder body welding rotation positioning devices 11, a tooth pressure ring 12, two pressure rings 13, a support ring device 14, and two support plate devices 15.

[0061] Operation sequence: first operate the flip assembly 8 to put the tooling in the correct preset position, lock the indexing plate 52 with the indexing locking pin device 49, then open the 4-piece screw clamping device 6, open the left positioning half ring 23 and the right positioning half ring 25 of the main positioning clamping device 3, then operate the 4-piece inner arc surface positioning device 4, lift the positioning plate 33 upwards, and the strong magnet 38 sucks the transition plate 37, then weld the small feed wheel intermediate cylinder and put it on, use the upper plane of the support ring device 14 to support the lower plane of the fourth layer of teeth welded on the small feed wheel intermediate cylinder, and weld the rotating positioning device 11 with the intermediate cylinder. The rotation of the small feeding wheel intermediate cylinder welding is fixed, because this positioning device is reasonably designed, the universalization of the left and right small feeding wheel intermediate cylinder welding can be realized, the positioning plate shaft 16 of the intermediate cylinder positioning clamping device 5 is used to fix the flange of the small feeding wheel intermediate cylinder welding, the upper positioning plate 17 is used to fix the intermediate cylinder of the small feeding wheel intermediate cylinder welding, and the clamping nut 18 is used to tighten, and then the small feeding wheel barrel welding is placed, and the barrel welding rotation positioning device 10 is used to fix the rotation position of the small feeding wheel barrel welding, because this positioning device is reasonably designed, the universalization of the left and right small feeding wheel barrel welding is realized. Then press the positioning plates 33 of the four inner arc surface positioning devices 4 in turn, disengage the strong magnet 38, and fix the inner arc surface of the fourth layer of teeth of the small feeding wheel intermediate cylinder welding and the inner arc surface of the small feeding wheel barrel welding. Then put the pressure ring 13 on the fourth layer of teeth of the small feeding wheel intermediate cylinder welding, and clamp it with the clamping device 7. Then operate the main positioning clamping device 3, close the left positioning half ring 23 and the right positioning half ring 25 (at this time, they are supported by the two roller support plate devices 2 and the two support plate devices 15, and the height position is fixed), and lock them with the clamping bolts (22) and the clamping nuts 29, so that the outer cylindrical surface of the small feeding wheel barrel weld is clamped. Then put the tooth pressure ring 12 on the upper plane of the left positioning half ring 23 and the right positioning half ring 25 (which is also the upper plane of the small feeding wheel barrel weld), and then operate the four-piece spiral clamping device 6 to clamp the tooth pressure ring 12, which actually clamps the small feeding wheel barrel weld. At this time, the weld seam of the small feeding wheel barrel weld and the small feeding wheel intermediate barrel weld is welded by carbon dioxide gas shielded welding. Then open the four-piece spiral clamping device 6 and remove the tooth pressure ring 12. Then, the first layer of teeth is placed on the upper plane of the left positioning half ring 23 and the right positioning half ring 25 (which is also the upper plane of the small feeding wheel barrel welded), and the rotation position of the first layer of teeth is fixed by the rotating positioning plate 26. Due to the reasonable positioning design, the first layer of teeth welded by the left and right small feeding wheels is universalized. Then, the tooth pressing ring 12 is placed on the first layer of teeth, and then the four-piece spiral clamping device 6 is operated to clamp the first layer of teeth, which actually clamps the small feeding wheel barrel welded. Then, the handle 50 of the turning assembly 8 is operated to turn the base plate 1 together with all the positioning clamping parts thereon to a suitable angle, and the indexing plate 52 is locked by the indexing locking pin device 49. Then, the small feeding wheel barrel welded, the small feeding wheel intermediate barrel welded, and all other welds of the first layer of teeth are welded.Then operate the flip assembly 8 and restore it to the preset front position, open the 4-piece spiral clamping device 6, open the 6-piece clamping device 7, unscrew the clamping nut 18, remove the gear pressure ring 12 and the 2-piece pressure ring 13, loosen the clamping nut 29, open the left positioning half ring 23 and the right positioning half ring 25 of the main positioning clamping device 3, open the barrel welding and rotating positioning device 10, and then remove the welded small feeding wheel for welding.

[0062] like Figure 4 As shown, the structural principle of the inner arc surface positioning device 4 is a planar four-bar structure, which is convenient for placing the parts on the tooling before welding and taking the parts up after welding. Due to the effect of friction, when taking the parts up, the positioning plate 33 will move up with the fourth layer of teeth welded on the middle cylinder and the inner arc surface welded on the cylinder body, and drive the connecting plate 36 to rotate around the rotating shaft 35, so that the positioning plate 33 moves inward, thereby separating from the fourth layer of teeth and the inner arc surface welded on the cylinder body, allowing the parts to be easily taken out. The function of the strong magnet 38 is: when placing the small feeding wheel intermediate cylinder welded and the small feeding wheel barrel welded on the tooling, first lift the positioning plate 33 upward until the transition plate 37 is attached to the vertical surface of the seat plate 32. At this time, the strong magnet 38 attracts the transition plate 37, so that the small feeding wheel intermediate cylinder welded and the small feeding wheel barrel welded are easily placed on the supporting ring device 14, and then press the positioning plate 33 in turn to disengage the strong magnet 38, and fix the inner arc surface of the fourth layer of teeth of the small feeding wheel intermediate cylinder welded and the inner arc surface of the small feeding wheel barrel welded.

[0063] The silage machine small feed wheel welding tool provided in the present application can accurately position and clamp the small feed wheel middle cylinder welding, small feed wheel cylinder welding, and first layer of teeth, and realizes the universal welding of left and right small feed wheels. It has a good effect on saving workshop space and improving the quality and production efficiency of small feed wheel welding, can greatly improve production efficiency, shorten production cycle, and has positive significance for batch production of small feed wheel welding.
