The fork frame assembly 2 includes a wheel frame plate 21 and a roller shaft 22. The wheel frame plate 21 is provided with a mounting through hole 211. The wheel frame plate 21 can be fixed on the positioning plate 12, and the mounting through hole 211 can be connected with the welding hole 121. The roller shaft 22 can be inserted into the mounting through hole 211. The positioning plate 12 has a first welding station and a second welding station. When the positioning plate 12 is rotated from the first welding station to the second welding station, the positioning plate 12 can drive the roller shaft 22 to rotate together so that the bottom end of the roller shaft 22 faces upward. In this embodiment, when the positioning plate 12 is located at the first welding station, welding can be performed between the upper side of the mounting hole 211 and the roller shaft 22. After rotating to the second welding station, welding can be performed between the bottom end of the roller shaft 22 and the lower side of the mounting hole 211 through the welding hole 121, thereby adjusting the welding angle and facilitating welding on the upper and lower sides.

[0023] In order to realize the rotation of the positioning plate 12, a rotating component 3 is also included. The rotating component 3 includes a driving cylinder 31, an active rotating shaft 32 and a driven rotating shaft 33. The active rotating shaft 32 and the driven rotating shaft 33 are respectively located at the two ends of the positioning plate 12, and are both rotatably connected to the bracket 11. The driving cylinder 31 is connected to the active rotating shaft 32 and is used to drive the active rotating shaft 32 to rotate. The driving cylinder 31 drives the positioning plate 12 to rotate through the active rotating shaft 32, and the driven rotating shaft 33 plays the role of rotation support.

[0024] In order to drive the active rotating shaft 32 to rotate, the rotating assembly 3 also includes an upper rack 34, a lower rack 35 and a rotating gear 36. The upper rack 34 is fixed on the piston rod of the driving cylinder 31, and the lower rack 35 is movably fixed on the bracket 11. The rotating gear 36 is sleeved on one end of the active rotating shaft 32, and the rotating gear 36 is meshed with the upper rack 34 and the lower rack 35 at the same time. When the upper rack 34 and the lower rack 35 are displaced, the rotating gear 36 can be driven to rotate, and the active rotating shaft 32 is driven by the rotating gear 36 to rotate, thereby realizing the rotation of the positioning plate 12.

[0025] In order to realize the positioning of the wheel frame plate 21 and the roller shaft 22, a positioning component 4 is also included. The positioning component 4 includes a first positioning member and a second positioning member.

The first positioning member is located on the four sides of the wheel frame plate 21 and is used to clamp the wheel frame plate 21. The second positioning member is located directly above the roller shaft 22 and is used to press the roller shaft 22 onto the wheel frame plate 21. That is, the wheel frame plate 21 is positioned by the first positioning member, and the roller shaft 22 is positioned by the second positioning member.

[0026] Specifically, the first positioning member includes a positioning block 41, an adjusting bolt 42 and a positioning cylinder 45. The positioning block 41 and the positioning cylinder 45 are arranged relatively on the four sides of the wheel frame plate 21, and each positioning block 41 is abutted against the side of the wheel frame plate 21 through the adjusting bolt 42. One end of the adjusting bolt 42 is threadedly engaged with the positioning block 41. By rotating the adjusting bolt 42, the adjusting bolt 42 can be moved horizontally, and abutted against the side of the wheel frame plate 21 through multiple adjusting bolts 42. At the same time, the positioning cylinder 45 can also abut against the side of the wheel frame plate 21 and cooperate with the adjusting bolt 42 to clamp the wheel frame plate 21.

[0027] Specifically, the second positioning member includes a support seat 43 and a clamping cylinder 44 located on the support seat 43. The clamping cylinder 44 is arranged on the support seat 43 in a vertical direction, and the piston rod of the clamping cylinder 44 can be extended into the positioning hole at the top of the roller shaft 22. By pressing down the clamping cylinder 44, the roller shaft 22 is kept in a state of close fit with the wheel frame plate 21, thereby fixing the roller shaft 22.

[0028] In this embodiment, the roller shaft 22 refers to a rotating shaft having a roller.
