Technical Field
[0001] This utility model relates to the technical field of positioning and flipping devices for large workpieces, specifically a positioning and flipping device for large workpieces. Background Technology
[0002] Large workpieces refer to workpieces with large dimensions, weight, or volume during manufacturing, processing, or assembly. These workpieces typically require special handling, transport, and assembly techniques to meet industrial production requirements. They are widely used in aerospace, heavy industry, shipbuilding, and mechanical engineering. A large workpiece positioning and flipping device is a specialized piece of equipment designed to help accurately position and flip large workpieces during manufacturing and processing. Because large workpieces are usually bulky and heavy, using traditional methods for positioning and flipping presents many challenges. Therefore, such devices are particularly important in modern industrial manufacturing. However, existing large workpiece positioning and flipping devices still have certain shortcomings. While traditional large workpiece positioning and flipping devices can be used effectively, during the large workpiece flipping process, after the material is flipped and placed, it can only be placed horizontally or vertically. This makes it inconvenient for workers to process the material at different angles and positions, and it cannot fine-tune the angle of the material. Furthermore, it cannot support the material after flipping, increasing the user's workload and reducing the equipment's flexibility, often causing problems for users. Utility Model Content

The scissor-type telescopic mechanism is a prior art technology, which is a telescopic structure composed of several sets of cross-hinged connecting rods, cylinders, and sliders. The cylinder pushes the slider, thereby changing the cross angle of several sets of connecting rods to achieve the purpose of telescopic extension. This application will not elaborate further on this. The scissor-type telescopic mechanism and the hydraulic cylinder work together to achieve the lifting of the scissor-type telescopic mechanism.
[0005] The angle fine-tuning mechanism includes a frame, a slider, a threaded rod, a rotating shaft, a connecting rod, and a push plate. Two sets of frames are fixedly installed on the top of the housing. A slider is slidably connected inside the frame, and a threaded rod is rotatably connected inside the frame. The slider and the threaded rod are threadedly connected. The slider is rotatably connected to the connecting rod through the rotating shaft.

The first lead screw meshes with the support frame, moving the flipping mechanism and clamping mechanism. Simultaneously, rotating the bidirectional lead screw moves the two clamping blocks, and the first hydraulic cylinder activates, causing the clamping plate to clamp and fix the material. Then, rotating the driven spur gear, through the meshing of the driven spur gear and the driving spur gear, flips the material. After the material is flipped, it is placed on the push plate. Rotating the threaded rod, through the meshing of the threaded rod and the slider, finely adjusts the angle of the push plate, facilitating further operation by the operator.

[0026] Working principle: When using a positioning and flipping device for large workpieces, the operator first places the material on the support plate 405. The drive wheel 6 is activated to move the support structure 4 below the equipment. Then, the second hydraulic cylinder 402 and the scissor-type telescopic mechanism 403 work together to raise the material. The first lead screw 102 is rotated, and through its engagement with the support frame 103, the flipping mechanism 2 and the clamping mechanism 3 move. Simultaneously, the bidirectional lead screw 302 rotates, moving the two clamping blocks 303. The activation of the first hydraulic cylinder 304 then causes the clamping plate 306 to clamp and fix the material. Then, the driven spur gear 203 is rotated, and the meshing of the driven spur gear 203 with the driving spur gear 204 drives the flipping plate 206 to rotate, thereby causing the material to flip. After the material has been flipped, the material is placed on the push plate 506. The threaded rod 503 is rotated, and the meshing of the threaded rod 503 with the slider 502 drives the connecting rod 505 to adjust the angle, thereby driving the push plate 506 to make a fine adjustment of the angle, thus making the angle of the material fine-tuned, which is convenient for the staff to perform further operations, thereby completing a series of tasks.
