[0024] like Figures 1-3 As shown, this utility model embodiment provides a base frame 9 flipping mechanism, including a support frame 1, a flipping platform 2, a flipping component, a clamping component, and a locking component;

[0025] The flipping component is set on the support frame 1 and connected to the flipping platform 2. The flipping component is used to drive the flipping platform 2 to flip relative to the support frame 1. The clamping component and the locking component are both set on the flipping platform 2 to fix the base frame 9 to be flipped.

[0026] The locking assembly includes a locking plate 8 and a safety bar. The locking plate 8 is fixed to the flipping platform 2 and has a locking hole 83 that cooperates with the safety bar. The safety bar includes a bar body 81 and a locking part 8272 disposed at one end of the bar body 81. The locking hole 83 includes a main hole for accommodating the safety bar and a secondary hole for accommodating the locking part 8272. When the bar body 81 is located inside the main hole, the secondary hole engages with the locking part 8272, and the other end of the bar body 81 abuts against the base frame 9 to be flipped.

[0027] One possible implementation also includes a lifting assembly, which includes a lifting component and a lifting beam 51. One end of the lifting component is disposed on the support frame 1, and the other end is connected to the lifting beam 51. The lifting component drives the lifting beam 51 to reciprocate along the height direction of the support frame 1. The tilting component is fixed to the lifting beam 51 and connected to the tilting platform 2. In addition, in this embodiment, there are two lifting assemblies, which are disposed at two ends of the tilting platform 2 that are far apart from each other. Each lifting component is provided with a corresponding tilting component. The symmetrical layout of the two lifting components enhances the lifting balance of the platform and prevents the risk of tilting caused by uneven force on one side.

[0028] In one possible implementation, there are two lifting components, which are respectively located at the two ends of the lifting beam 51 that are far apart from each other. The lifting components include hydraulic cylinders 5, which serve as the lifting power source, providing high output force and smooth movement characteristics, suitable for operation of heavy-duty chassis 9. The two hydraulic cylinders 5 are located at both ends of the lifting beam 51 to further optimize the load distribution and extend the service life of the equipment.

[0029] In one possible implementation, the clamping assembly includes a slider clamping member 6 and a nut locking member. Both the slider clamping member 6 and the nut locking member are mounted on the flipping platform 2. The slider clamping member 6 includes two sliders that are slidably connected. The nut locking member includes a rotating part 7 located on the outside of the flipping platform 2, a locking part 8272 located on the inside of the flipping platform 2 and in contact with the base frame 9 to be flipped, and a threaded rod 71 that passes through the flipping platform 2, is threadedly connected to the flipping platform 2, and connects the rotating part 7 and the locking part 8272. The combined clamping of the slider and the nut locking member provides flexible clamping force adjustment, is compatible with various base frame 9 structures, and reduces changeover time.

[0030] One possible implementation method is described below. Figures 2-3 It also includes a positioning component, which includes four positioning rods 31 and positioning blocks 3. Each positioning rod 31 corresponds to a positioning block 3. The four positioning blocks 3 are respectively set at the four corners of the flipping platform 2. The positioning blocks 3 are provided with positioning holes for cooperating with the positioning rods 31. The positioning rods 31 pass through the positioning holes and contact the top corner of the base frame 9 to be flipped. The positioning components set at the four corners accurately cooperate with the positioning rods 31 and the positioning holes to eliminate the offset of the base frame 9 and improve the welding or assembly accuracy.

[0031] In one possible implementation, the tilting assembly includes a geared motor 4 and a slewing bearing 41. The geared motor 4 is fixed to the lifting beam 51. One end of the slewing bearing is connected to the tilting platform 2, and the other end is connected to the motor shaft of the geared motor 4.

[0032] The specific implementation method of this application will be described in detail below with reference to the above structure:

[0033] This application comprises a support frame 1, a tilting platform 2, a tilting assembly, a clamping assembly, and a locking assembly. The support frame 1 adopts a gantry structure. The tilting platform 2 is connected to a reduction motor 4 via a slewing bearing 41. The reduction motor 4 drives the tilting platform 2 to rotate around its axis, achieving multi-angle tilting from 0-180°. When it is necessary to lift the bottom of the welding base 9 or for other working conditions, the hydraulic cylinders 5 are symmetrically installed on both sides of the support frame 1, pushing the lifting beam 51 to move vertically along the frame guide rail, thus enabling the tilting platform 2 to have height adjustment capabilities. Furthermore, the clamping assembly includes a slider clamping member 6 locked with a nut. When the base frame 9 is placed on the flipping platform 2, the slider moves along the platform slide rail to adapt to the width of the base frame 9. The threaded rod 71 of the nut locking part passes through the platform. By rotating the outer rotating part 7, the inner locking part 8272 is driven to press the base frame 9, ensuring uniform clamping force. The locking assembly adopts a linkage design between the locking plate 8 and the safety rod. After the locking part 8272 of the safety rod is embedded in the secondary hole of the locking hole 83, the rod body 81 abuts against the base frame 9, forming a double lock to prevent accidental loosening during flipping. At the same time, the four corner positioning rods 31 are inserted into the positioning holes of the positioning block 3 to accurately constrain the position of the base frame 9, ensuring alignment during welding or inspection and significantly reducing labor intensity.

[0034] In one possible implementation, the lifting beam 51 is slidably connected to the support frame 1 to reduce frictional loss and ensure a smooth lifting process without jamming.

[0035] In one possible implementation, the rod 81 and the locking part 8272 are an integral structure, which enhances the locking reliability and avoids the risk of failure caused by loose parts.

[0036] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
