The four corners of the upper and lower frames are connected by support columns. Multiple pairs of first crossbeams are installed laterally inside the upper frame. Multiple square nylon plates for supporting shaft assemblies are installed on each pair of first crossbeams. Circular positioning holes for the shaft assemblies to pass through are vertically opened in the center of the nylon plates. A pair of first longitudinal beams are installed longitudinally inside the lower frame. Support legs are installed on the lower surface of each of the four corners of the lower frame, and rollers are installed at the bottom of the support legs.

[0027] Example:
[0028] This embodiment provides a transfer vehicle for shaft assemblies, such as... Figures 2 to 4 As shown, the vehicle includes a body frame 1, which comprises a rectangular upper frame 11 and a lower frame 12. The four corners of the upper frame 11 and the lower frame 12 are connected by support columns 13. The upper frame 11 has multiple pairs of first crossbeams 14 installed horizontally inside, and each pair of first crossbeams 14 has multiple square nylon plates 2 for supporting shaft assemblies 3. The nylon plates 2 have circular positioning holes 21 in the middle vertically for the shaft assemblies 3 to pass through. The lower frame 12 has a pair of first longitudinal beams 15 installed longitudinally inside, and support legs 16 are installed on the lower surface of the four corners of the lower frame 12. Rollers are installed at the bottom of the support legs 16.
[0029] The transfer vehicle in this embodiment adopts a frame structure, which can ensure support strength, reduce overall weight, and facilitate movement. The core shaft 31 of the shaft assembly 3 passes vertically through the positioning hole 21 of the nylon plate 2. The shaft shoulder 32 or gear ring 32 on the shaft assembly 3 is engaged on the nylon plate 2 at the edge of the positioning hole 21. The nylon plate 2 with different sizes of positioning holes 21 can be selected according to the shaft diameter or the size of the gear ring 33 of different shaft assemblies 3, so that this transfer vehicle is suitable for the placement of different types of shaft systems and can protect the bottom of the shaft system from collision.
[0030] Furthermore, in this embodiment, the diameter of the positioning hole 21 is 15-25cm. These dimensions are applicable to most shaft systems, thus improving the applicability of this transfer vehicle.
[0031] As a preferred embodiment, in this embodiment, multiple second longitudinal beams 17 are installed longitudinally inside the upper frame 11, and multiple pairs of first crossbeams 14 have first through holes for the second longitudinal beams 17 to pass through. Each second longitudinal beam 17 is located below a row of longitudinally arranged nylon plates 2. Multiple second crossbeams 18 are installed transversely inside the lower frame 12, and a pair of first longitudinal beams 15 have second through holes for the second crossbeams 18 to pass through. The above connection method improves the overall strength of the transfer vehicle, avoids loosening and damage at the connection points of the transfer vehicle due to uneven stress during long-term use, and can provide support space and fulcrum for the lifting mechanism of the AGV. The first crossbeams 14 and the second longitudinal beams 17 are integrated into a planar support body, which can effectively and stably support the shaft assembly 3 through the nylon plates 2.
[0032] As a preferred embodiment, the nylon plate 2 is mounted on a pair of first crossbeams 14 by fixing bolts. The pair of first crossbeams 14 support the nylon plate 2 evenly upwards. Different nylon plates 2 with different diameter positioning holes 21 can be quickly replaced by fixing bolts, thereby improving assembly and transfer efficiency.
[0033] As a preferred embodiment, the rollers in this embodiment include a pair of directional casters 4 and a pair of swivel casters 5. The directional casters 4 are installed at the bottom of a pair of support legs 16 at the longitudinal rear end, and the swivel casters 5 are installed at the bottom of a pair of support legs 16 at the longitudinal front end. In use, the directional casters 4 can prevent deviation, and the swivel casters 5 can provide directional guidance, which is suitable for long-distance transportation of heavy shaft assemblies 3.
[0034] As a preferred embodiment, a QR code recognition plate 6 is detachably installed in the middle of the lower part of one of the first longitudinal beams 15, making the transfer vehicle suitable for automatic transport after scanning by a hidden AGV. The QR code recognition plate 6 is made of metal to avoid wear during use.
[0035] As a preferred embodiment, in this embodiment, there are at least three pairs of first crossbeams 14, at least two first longitudinal beams 15 and second longitudinal beams 17, and at least four second crossbeams 18.
[0036] As a preferred embodiment, the upper frame 11 is equipped with a handle 7 at its longitudinal rear end, which facilitates manual pushing of the transfer vehicle to the assembly line.
[0037] In actual operation of this embodiment:
[0038] 1. Picking personnel obtain picking instructions from the management dashboard, select the appropriate size nylon sheet 2 for the required shaft parts, and install the nylon sheet 2 onto the first crossbeam 14. The transfer method can be manual or AGV transfer. In manual transfer mode, the operator manually operates handle 7 to push the transfer cart from the parts sorting area to the line-side workstation. In AGV transfer mode, the AGV travels under the transfer cart according to the scheduling instructions, identifies the QR code on the QR code identification plate 6 on the bottom of the cart using laser radar, and the lifting mechanism lifts the transfer cart chassis, transporting the cart to the target assembly line.
[0039] 2. After the transfer vehicle arrives at the line, since the shaft assembly 3 is placed vertically, the bottom of the shaft assembly 3 passes through the positioning hole 21, and the corresponding shaft shoulder 32 or gear ring 33 is stuck on the nylon plate 2. The above operations can be carried out manually by using lifting tools, or automated equipment can be set up to use the robotic arm of an industrial robot to pick up and place materials. After the assembly is completed, the empty vehicle can be pushed to the designated recycling area through AGV automatic handling mode and manual mode.
