[0027] Positioning mechanisms 11 for positioning and supporting the rotating shaft 5 are arranged on the upper parts of both ends of the rotating shaft 5. The positioning mechanisms 11 realize the support and rotation of the rotating shaft 5 to ensure the stability during the flipping process.

[0028] The turning mechanism 7 includes a hydraulic cylinder 701, a slide rail 702, a rack 703 and a slider 704. The hydraulic cylinder 701 is fixedly installed at the bottom of the other two sides of the workbench 1, and the output shaft end of the hydraulic cylinder 701 is fixedly connected to the slider 704 arranged at the bottom of the slide rail 702. Racks 703 are symmetrically arranged at both ends of the slide rail 702. The rack 703 is meshed with the gear 6, and the gear 6 is arranged on the inner side of one end of the rack 703, so that in the process of driving the gear 6 at one end to turn over, the gear 6 at the other end is disengaged from the rack 703 at the other end, thereby realizing the lifting of the other end of the assembly fixed plate 4. The turning mechanism 7 also includes a slide groove 705 and a first through groove 706 opened on the other two sides of the workbench 1. The slide groove 705 is opened on the top surface of the other two sides of the workbench 1, and the slide groove 705 is slidably connected to the slide rail 702.

[0031] Embodiment 2:

[0032] Based on the first embodiment, the positioning mechanism 11 mentioned in the first embodiment is described as follows:

[0033] The positioning mechanism 11 includes a servo motor 111, a worm 112, a turbine 113 and a screw 114. The servo motor 111 is fixedly installed at the bottom of one side of the workbench 1, and the output shaft of the servo motor 111 is fixedly connected to one end of the worm 112 through a coupling. The worm 112 is transmission-connected to the turbine 113 arranged at one end of the screw 114. The screw 114 is rotatably arranged at the center of the bottom of both sides of the workbench 1. The positioning mechanism 11 also includes a moving frame 115 and a positioning plate 116. The moving frame 115 is arranged at both ends of the screw 114, and the bottom center of the moving frame 115 is threadedly connected to both ends of the screw 114. The positioning plate 116 is arranged on both sides of the top of the moving frame 115, and the bottom surface of the positioning plate 116 is rotatably connected to the rotating shaft 5.

[0034] The positioning plate 116 is slidably connected to the second through slot 10 at the top of the second support block 9. The second support block 9 is arranged on the outside of the first support block 2. By setting the second support block 9 and the second through slot 10, the stability of the positioning plate 116 during horizontal movement is ensured.

[0035] In this embodiment, by setting the positioning mechanism 11, the two ends of the rotating shaft 5 at both ends of the assembly fixing plate 4 are switched to press and support the rotation function, thereby ensuring the stability of the device during the driving flipping process. The servo motor 111 drives the worm 112 to rotate, so that the worm 112 drives the turbine 113 at one end of the screw 114 to rotate. Since the two ends of the screw 114 are threadedly connected to the bottom center of the two moving frames 115, the two moving frames 115 move in one direction along the screw 114 at the same time, thereby realizing the positioning and supporting rotation of the two ends of the rotating shaft 5. When the two moving frames 115 move to the right at the same time (refer to the attached manual Figure 1 ), the positioning plate 116 on the left side of the workbench 1 slides out from the second through slot 10 to the top surface of the rotating shaft 5 at one end, and the side wall of the rotating shaft 5 is rotatably connected to the bottom surface of the positioning plate 116, which plays a positioning support function for the rotation of the rotating shaft 5.

Similarly, when the two moving frames 115 move to the left at the same time (refer to the attached manual), Figure 2 ) to realize the positioning support of the rotating shaft 5 at the other end, thereby ensuring the stability of the assembly fixing plate 4 during the flipping process.

[0036] Working principle: First, the cab assembly is fixed on the assembly fixing plate 4 by the fixing tool of the prior art. When the assembly needs to be flipped to one side, the servo motor 111 is first driven to drive the worm 112 to rotate to one side, so that the two moving frames 115 move to the right side along the screw 114 at the same time, so that the positioning plate 116 on the left side moves to the top surface of the rotating shaft 5 at one end, and then the hydraulic cylinders 701 on both sides are synchronously driven at the same time, so that the output shaft contracts inwards and drives the slide rail 702 to move to the right side, thereby driving the gear 6 on the rotating shaft 5 at one end to rotate, and realizing the flipping of one side of the assembly (refer to the attached manual). Figure 1 ), similarly, when the assembly needs to be flipped to the other side, the servo motor 111 is driven to drive the worm 112 to rotate to the other side, and the hydraulic cylinder 701 is pushed outward synchronously to realize the flipping of the other side of the assembly (refer to the attached manual Figure 2 ).
