[0002] In the machining industry, machining large parts such as shafts often involves multiple process changes, each of which may require flipping and repositioning the workpiece. Existing techniques often rely on manual operation or the use of simple support frames, which are not only inefficient but also pose safety risks. With the increasing automation in the manufacturing industry, the safe and efficient lifting and flipping of large shafts has become a pressing issue. Utility Model Content

[0007] The hoisting device is connected to the end of the main shaft away from the turning frame and is used to cooperate with the overhead crane.

[0008] By adopting the above-mentioned technical solution, the main shaft can be effectively supported and a safe and reliable flipping operation can be achieved. Specifically: in the flip preparation stage, the support frame provides stable support for the placement of the main shaft, which facilitates the installation and placement of the lifting device and the flipping device. The structural design of the flipping frame, especially the combination of the flip plate and the connecting beam, enables the main shaft to maintain balance during the flipping process, reducing the risk of rolling and displacement in the horizontal direction. The design of the card slot facilitates the placement of the main shaft flange, ensuring that the main shaft will not slip out during flipping, thereby improving the safety of operation. The lifting device is connected to the end of the main shaft away from the flipping frame, which is convenient for cooperation with the overhead crane, achieving a smooth flipping of the main shaft and reducing the difficulty and risk of operation.

[0009] Preferably, a reinforcement plate is further included, wherein the reinforcement plate is connected to both the flip plate and the connecting beam, and the reinforcement plate is perpendicular to both the flip plate and the connecting beam.

[0010] By adopting the above technical solution, the reinforcement plate is connected to the turnover plate and the connecting beam and is perpendicular to each other, thereby enhancing the overall structural stability of the turnover frame and improving the safety and reliability of the large-axis turnover process.

[0011] Preferably, a protective pad is laid in the card slot.

Specifically, the fixed plate is fixed to the main shaft via fixing bolts, ensuring a secure connection between the lifting device and the main shaft, improving the stability of the lifting process. Multiple lifting rings are evenly distributed on the fixed plate, distributing the load points during lifting, avoiding safety hazards caused by excessive localized force, and further enhancing the safety and reliability of the lifting process.

[0015] Preferably, the fixed plate is connected to a counterweight block, and the counterweight block and any one of the lifting rings are located on the same vertical line, and the vertical line passes through the center of the fixed plate.

[0016] By adopting this technical solution, the counterweight remains at the bottom of the fixed plate, determining the position of the fixing bolts on the fixed plate and facilitating their installation. Furthermore, the counterweight and each fixing bolt are located on a vertical line passing through the center of the fixed plate. This ensures that both the fixture and the main shaft remain balanced during lifting, ensuring the main shaft's stability during rotation.

[0017] Preferably, a protective pad is provided between the support frame and the main shaft, and the protective pad is fixedly connected to the support frame.

[0031] It can effectively support the main shaft and realize safe and reliable flipping operation. Specifically: in the flip preparation stage, the support frame 1 provides stable support for the placement of the main shaft, which is convenient for the installation and placement of the lifting device 6 and the flipping device. The structural design of the flipping frame 3, especially the combination of the flipping plate 31 and the connecting beam 32, enables the main shaft to maintain balance during the flipping process, reducing the risk of rolling and displacement in the horizontal direction. The design of the slot 311 facilitates the placement of the main shaft flange, ensuring that the main shaft will not slip out during flipping, and improving the safety of operation. The lifting device 6 is connected to the end of the main shaft away from the flipping frame 3, which is convenient for cooperation with the overhead crane, realizing the smooth flipping of the main shaft and reducing the difficulty and risk of operation.

[0032] Reference Figure 3 The support frame 1 includes a vertical beam 11, a horizontal beam 12, and a support plate 13. There are two vertical beams 11, and the horizontal beam 12 is arranged between the two vertical beams 11. The two ends of the horizontal beam 12 are fixedly connected to the corresponding vertical beam 11. The bottom end of the vertical beam 11 is fixedly connected to a bottom plate. The bottom plate is arranged horizontally, and the cross-sectional area of ​​the bottom plate is larger than the cross-sectional area of ​​the vertical beam 11. The vertical beam 11 is fixedly connected to a rib plate. The longitudinal cross-section of the rib plate is a right triangle. The bottom of the rib plate is fixedly connected to the bottom plate. There are multiple rib plates, which are distributed circumferentially along the vertical beam 11.

[0033] Reference Figure 3Two support plates 13 are provided, one corresponding to each of the two vertical beams 11. Each support plate 13 is fixedly connected to the top of each vertical beam 11. The top surfaces of the vertical beams 11 are tilted, and the support plates 13 are tilted upward from one end of the two vertical beams 11 that are closest to each other to the other end. A protective pad 2 is fixedly connected to the top of each support plate 13. The main shaft rests on the two support plates 13, abutting the protective pad 2.

[0034] The protective pad 2 reduces the possibility of the main shaft being worn or scratched due to direct contact with the support frame 1 during the turning process, thereby improving the integrity of the main shaft surface and extending its service life.

[0035] Reference Figure 2 The vertical surface where any flip plate 31 is located is perpendicular to the vertical surface where the connecting beam 32 is located. The bottoms of the slots 311 are located on the same circle, and the depths of any two slots 311 are the same.

Specifically, the fixed plate 61 is fixedly connected to the main shaft via fixing bolts 62, ensuring a secure connection between the lifting device 6 and the main shaft, improving the stability of the lifting process. Multiple lifting rings 63 are evenly distributed on the fixed plate 61, dispersing the load points during lifting, avoiding safety hazards caused by excessive localized force, and further enhancing the safety and reliability of the lifting process.

The main shaft turning auxiliary tooling realizes safe and efficient turning of the main shaft through the coordinated action of the support frame 1, the turning frame 3 and the lifting device 6.

[0046] Specifically: During the flipping preparation stage, the support frame 1 provides stable support for the placement of the main shaft, facilitating the installation and placement of the hoisting device 6 and the flipping device. The structural design of the flipping frame 3, especially the combination of the flipping plate 31 and the connecting beam 32, enables the main shaft to maintain balance during the flipping process, reducing the risk of rolling and displacement in the horizontal direction. The design of the slot 311 facilitates the placement of the main shaft flange, ensuring that the main shaft will not slip out during flipping, thereby improving the safety of operation.
