Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a rapid prototyping elevator structure. Background Technology

[0002] The elevator is a key component of the aircraft control system, and it has extremely high requirements for weight, strength, surface accuracy and fatigue life.

[0003] Traditional elevator manufacturing typically employs a two-stage curing process. The first curing stage forms the internal load-bearing frame structure, such as the end ribs and C-beams. The second curing stage assembles and positions the pre-formed frame, filling material, and metal embedded parts, covers them with the outer skin prepreg, and then performs overall co-curing. This process is complex, time-consuming, requires two independent curing cycles, occupies a lot of equipment time, slows down production flow, and requires multiple sets of molds for both frame component forming and final assembly. The initial component preparation and the two laying operations both require a significant amount of manpower. In view of this, existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a rapid prototyping elevator structure, including a main beam body and a main beam frame, one end of the main beam frame being connected to the side wall of the main beam body, and a filling and fixing structure being provided inside the main beam frame;

[0005] The filling and fixing structure includes: four positioning grooves, four filling plates, four positioning pins, several first pressing grooves, two pressure plates, and an isolation positioning component;

[0006] Four positioning slots are evenly formed on the rear wall of the main beam frame. Four filling plates are movably embedded in the main beam frame. Four positioning pins are located on the rear wall of the four filling plates and are movably embedded in the four positioning slots. A plurality of first clamping slots are formed on the upper and lower walls of the main beam frame and the four filling plates. Two pressure plates are located at the upper and lower ends of the main beam frame and are located in the plurality of first clamping slots. The isolation positioning component is installed in the main beam frame and connected to the two pressure plates.

[0007] Preferably, the isolation positioning assembly includes: three ribs, three weight-reducing cavities, several support rods, six positioning blocks, and six positioning holes;

[0008] The three ribs are connected to the inner side walls of the main beam frame at both ends. The three weight-reducing cavities are respectively opened at the center of the three ribs. Several support rods are respectively installed on both sides of the three weight-reducing cavities. The six positioning blocks are respectively installed at the center of the upper and lower ends of the three ribs. The six positioning holes are respectively opened at the upper ends of the two pressure plates.

[0009] Preferably, a second clamping groove is provided on the lower wall surface of each of the three ribs.

[0010] Preferably, metal connectors are installed at both ends of the main beam body.

[0011] Preferably, the three ribs are located between the four filler plates.

[0012] Beneficial effects

[0013] This invention provides a rapid prototyping elevator structure with the following advantages: the filling and fixing structure allows the entire elevator main structure to be formed in a single curing process, eliminating the need for separate curing processes for intermediate components, significantly shortening the manufacturing cycle. Furthermore, only one set of assembly molds is required to complete all core molding work, saving the cost of multiple sets of skeleton component molds. The integrated design and one-step molding process simplify operation, reducing the number of operators to two, significantly lowering the elevator manufacturing cost. Single co-curing helps form a more uniform and robust interface bond between components, reducing the risk of errors and deformation caused by multiple operations and assembly, and potentially improving the surface accuracy and structural integrity of the final product.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figure 1-3 A rapid prototyping elevator structure includes a main beam body 1 and a main beam frame 2. One end of the main beam frame 2 is connected to the side wall of the main beam body 1, and a filling and fixing structure is provided inside the main beam frame 2.

[0020] The filling and fixing structure includes: four positioning grooves 3, four filling plates 4, four positioning pins 5, several first clamping grooves 6, two pressure plates 7, and isolation and positioning components;

[0021] Four positioning slots 3 are evenly opened on the rear wall of the main beam frame 2. Four filling plates 4 are movably embedded in the main beam frame 2. Four positioning pins 5 are located on the rear wall of the four filling plates 4 and are movably embedded in the four positioning slots 3. Several first pressing slots 6 are opened on the upper and lower walls of the main beam frame 2 and the four filling plates 4. Two pressure plates 7 are located at the upper and lower ends of the main beam frame 2 and are located in several first pressing slots 6. The isolation positioning component is installed in the main beam frame 2 and connected to the two pressure plates 7.

[0022] During assembly, workers first pre-process the foam core filling board 4 into a specific shape according to the final design surface and internal structural space requirements of the elevator. Then, an isolation film is applied to the outer surface of the pre-formed foam filling board 4, and a certain number of layers and orientations of carbon fiber prepreg are laid on the outside of the film according to design requirements. The metal connector 14 is then covered with an isolation film, and a certain number of layers and orientations of glass fiber prepreg are laid on the outside of the film according to design requirements. The filling board 4 is then embedded into the main beam frame 2, and the positioning pin 5 at one end of the filling board 4 is embedded into the positioning groove 3 for auxiliary fixation. Subsequently, two pressure plates 7 are placed above and below the filling board 4 and the main beam frame 2, respectively, in the first pressing grooves 6, to further press the filling board 4. After fixing, the pressure plate 7 is snapped in place by isolation positioning. After assembly, carbon fiber prepreg is laid as the outer skin in the lower mold cavity of the molding mold according to the design requirements of the elevator skin. During this laying process, a back wrapping cloth with sufficient width and length is reserved at the edge of the skin prepreg. The assembled workpiece is accurately placed on the skin prepreg that has been laid in the lower mold cavity of the mold. Then, the reserved skin back wrapping cloth is pulled up and tightly wrapped around the workpiece to ensure that the wrapping is in place, without wrinkles, and with good overlap. After completing the above combination, laying, and back wrapping, the upper mold is closed and cured according to the selected composite material. During the curing process, the skin, foam core covering layer, embedded part covering layer and back wrapping part are integrated into a whole structure to achieve rapid molding of the elevator.

Several support rods 10 are respectively installed on both sides of the three weight-reducing cavities 9. Six positioning blocks 11 are respectively installed at the center of the upper and lower ends of the three ribs 8. Six positioning holes 12 are respectively opened at the upper ends of the two pressure plates 7.

[0025] During the assembly process, three ribs 8 are used to isolate multiple filler plates 4, while ensuring the overall strength of the main beam frame 2. The weight reduction cavity 9 is used to reduce the overall weight of the ribs 8, and several support rods 10 are used to ensure the overall strength of the ribs 8. Then, the six positioning blocks 11 at the upper and lower ends of the ribs 8 cooperate with the positioning holes 12 at the upper end of the pressure plate 7 to achieve the snap-fit ​​and limit of the pressure plate 7.

[0026] In the specific implementation process, a second pressing groove 13 is provided on the lower wall of each of the three ribs 8. The second pressing groove 13 ensures the tight fit between the pressing plate 7 and the rib 8.

[0027] In the specific implementation process, metal connectors 14 are installed at both ends of the main beam body 1, and the main beam body 1 can be connected and installed in the future through the metal connector frame.

[0028] In the specific implementation process, the three ribs 8 are located between the four filler plates 4 respectively. The filler plates 4 are isolated by the ribs 8 to ensure the uniform distribution of the filler plates 4.
