Description

Technical Field

[0001] The invention relates to the field of aircraft assembly technology tooling, in particular to a modular reconfigurable self-adaptive assembly work platform and an assembly method. Background Art

[0002] Against the backdrop of rapid iteration of aircraft models and increasingly urgent demand for low-cost development of new aircraft, modern aircraft have increasingly higher requirements for assembly quality and efficiency, and the demand for rapid production conversion of aircraft models is becoming increasingly strong. Aviation manufacturing companies are paying more and more attention to cost control and efficiency improvement in aircraft development.

[0003] Traditional assembly jigs are mostly customized and manufactured for the assembly needs of aircraft products, and the tooling has poor reconfigurability and versatility. Therefore, a large number of assembly jigs need to be designed and manufactured for a certain model of aircraft production line, which not only increases the production and manufacturing cost of the aircraft, prolongs the aircraft manufacturing cycle, but also takes up valuable storage space. With the increase in the development tasks of various new aircraft models, the design, manufacture, management and storage of assembly jigs will bring higher and higher costs. Therefore, it is currently necessary to realize the reconfigurability and adaptability of aircraft assembly jigs, and before that, it is necessary to realize the reconfigurability and adaptability of the assembly platform used to place the assembly jigs.

[0004] Traditional assembly platforms are mostly customized and manufactured for the assembly needs of aircraft assembly tools, and their reconfigurability and adaptability are poor. Therefore, modular assembly platforms are an important research direction to achieve the reconfigurability and adaptability of assembly platforms. Currently, existing modular platforms mainly adapt to the positioning needs of different models by adjusting the position of the column and the base and the relative position of the positioner and the column side panel. However, leveling the height and direction of the modular assembly platform is not a simple matter, and the existing modular platforms have extremely high dimensional standard requirements when adjusting, so quality control is difficult during the manufacturing process. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art such as poor reconfigurability and adaptability of assembly platforms and difficulty in quality control, and to provide a modular reconfigurable and adaptive assembly work platform with good reconfigurability, strong adaptability, simple manufacturing and easy control of platform quality.

Furthermore, the connecting fixture in the hanging extension block is in the form of a hook, the connecting fixture in the flip-up extension block is in the form of an upward hinge, and the connecting fixture in the flip-down extension block is in the form of a downward hinge.

[0022] Since a modular reconfigurable adaptive assembly work platform carries a large load during operation, the frames of each unit are made of aluminum profiles. In addition to the convenience of disassembly and assembly, aluminum profiles have good corrosion resistance, good strength resistance, high recycling rate, and good processing performance, making them suitable for large-scale frame assembly.

[0030] The modular reconfigurable adaptive assembly work platform assembly method described in the present invention can be assembled on site as the assembly parts of the assembly platform are all modular and standardized parts, and has extremely high adaptability without the need for customization in advance. A plurality of step module components form a plurality of tower units, and the plurality of tower units are unified into a platform module, but the tower units are independent of each other, so the tower units are self-contained, and the tower units can be disassembled and installed separately, which has extremely high reconfigurability, and the platform components only need to meet the requirements of standardization and modularization, and the requirements for the accuracy of the size are relatively low, so it is relatively easy to manufacture and the platform quality is easy to control.

[0036] Preferably, in a modular reconfigurable adaptive assembly work platform assembly method, the order of step 3 and step 4 can be interchangeably performed.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The modular reconfigurable adaptive assembly work platform described in the present invention is a large frame formed by the fixed connection of the platform module and the support assembly as the platform body. The platform body is spliced ​​by component module units such as the step module assembly and the column module. It can be adapted to a variety of different assembly scenarios, is not limited by the constraints of the work site, and has strong adaptability. On the basis of the large frame formed by the fixed connection of the platform module and the support assembly, an extended work area is set up to fix the extension block module and the platform module with a plate-type limiter as the connecting component. Due to the high height of the column module, a protective fence and a trapezoidal module are also set up to ensure the safety of the entire work platform.

[0039] The step module components, column modules and other modules of the assembly platform are all large modules that can be assembled. They only need to be modularized and standardized, and there is no excessive requirement for size. Therefore, the assembly platform module is simple to manufacture and the platform quality is easy to control. Since the platform module includes several tower units, several tower units and modules are adapted to form an overall platform. However, in fact, due to the independence of the tower unit, the modules that cooperate with it are actually independent. The independent modules can be coordinated with the actual working environment and have strong reconfigurability.

[0040] 2. The modular reconfigurable adaptive assembly work platform described in the present invention expands the platform area during the actual working process by setting extension block modules and positioning parts, ensuring that the problem of the distance between the platform and the working area being too long can be compensated, thereby increasing the area of ​​the specific area of ​​the platform module. It is also easy to install and disassemble and has strong adaptability.

[0041] 3. The modular reconfigurable adaptive assembly work platform described in the present invention is formed by splicing and fixing a plurality of modular components. For different working environments, the platform structure that meets the requirements can be obtained by simply changing the number of modular components. It has extremely high adaptability. The materials of the modular components are mostly aluminum profiles and composite wood boards, which are cheap. The modules of the platform are mostly screwed together to build the platform. After the platform is used, the screwed components can also be disassembled. The components of the platform are highly reconfigurable, and the disassembled platform components can be reused, which improves economic benefits.

[0042] 4. The modular reconfigurable adaptive assembly work platform assembly method described in the present invention can be assembled on site as the assembly parts of the assembly platform are all modular and standardized parts, and has extremely high adaptability without the need for advance customization. Several step module components form multiple tower units, and multiple tower units are unified into one platform module, but each tower unit is independent of each other, so each tower unit is self-contained, and each tower unit can be disassembled and installed separately, which has extremely high reconfigurability. Moreover, each component of the platform only needs to meet the requirements of standardization and modularization, and the requirements for dimensional accuracy are relatively low, so it is easier to manufacture and the quality of the platform is easy to control.

DETAILED DESCRIPTION

[0063] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0064] Example 1

[0065] The present invention presents a modular, reconfigurable and adaptive assembly work platform. Under the background conditions that traditional assembly platforms have poor reconfigurability and adaptability, and quality control of existing modular assembly platforms is difficult, but the requirements of actual engineering needs are constantly increasing, a reconfigurable and adaptable assembly work platform that can meet the needs of different scenarios and different models is expressed.

[0066] like Figure 1A modular reconfigurable adaptive assembly work platform is shown, comprising: a platform module 1, a support assembly 2, a guardrail 3, a trapezoidal module 4, a plate-type limiter 5, and an extension block module 6. The platform module 1 comprises a plurality of planar structures that are not connected to each other, the platform module 1 comprises a plurality of tower units, and the tower units are formed by splicing a plurality of step module assemblies 11; the support assembly 2 comprises a plurality of column modules 21, and the support assembly 2 is arranged at the bottom of the platform module 1; the guardrail 3 comprises a horizontal guardrail 31 and an oblique guardrail 32, and the horizontal guardrail 31 is arranged on one side or both sides of the platform module 1; the trapezoidal module 4 is connected to one end or both ends of the platform module 1, and oblique guardrails 32 are arranged on both sides of the trapezoidal module 4; a plate-type limiter 5 is arranged against one side of the platform module 1; the extension block module 6 is arranged on the plate-type limiter 5, and the upper plane of the extension block module 6 is parallel to the upper surface of the platform module 1.

[0067] Specifically, Figure 1 As shown, since the above-mentioned working platform needs to meet the assembly requirements of different scenes and different models, the platform module 1 is a general term for multiple tower units, and the tower unit includes a platform tower unit 1-a arranged diagonally and a platform tower unit 2 1-b arranged horizontally. The tower units can be arranged independently, or they can be fixedly combined by multiple tower units 1-a and tower units 2 1-b.

[0068] The platform module 1 can be generally considered to be composed of a plurality of step module components 11 which are fixedly connected together. Figure 3 As shown, the four corners of the bottom of the platform module assembly 11 are provided with end surface connection plates 111, and the periphery of the platform module assembly 11 is a metal aluminum frame, and the metal aluminum frame is provided with a support surface formed by bonding and tightly connecting multiple layers of plates of different materials such as aluminum profiles and composite wood boards. The cross section of the platform module assembly 11 is square, and the upper surface is a square plane structure. In terms of ease of manufacturing and installation and variability, the size of the platform module assembly is length × width × height: 2000mm × 1500mm × 155mm, which is a better solution.

[0069] More specifically, since platform module 1 is the work area for assembly and construction and has a large load-bearing capacity, the aluminum profile can be 40120 aluminum profile, which can be used in frame combinations of heavy-duty structures with high stress, high strength, and high support requirements, and has excellent load-bearing capacity. Composite wood boards can be composite anti-skid wood boards, which can reduce falls and improve safety.

[0070] Each plane is formed by a plurality of platform module assemblies 11 fixedly connected, and the sides of two adjacent platform module assemblies 11 of the same length fit together, and the two sides are fixed with countersunk hexagon socket screws. Repeat the above steps to connect into a plane. And the connection direction between two adjacent platform module assemblies 11 is not limited to the same direction. On the basis of the above, the connection direction of the platform module assemblies 11 can be circumferentially laid to form a plane with uniform width and length.

[0071] like Figure 4 As shown, the support assembly 2 includes all the column assemblies 21 in the entire modular reconfigurable adaptive assembly work platform. In a modular reconfigurable adaptive assembly work platform, since the upper and lower positional relationships of the multiple planes included in the platform module are inconsistent, the heights of the column assemblies 21 are also different. Figure 5 As shown, the column assembly 21 includes an end surface connection plate 211, a column 212 and a bottom plate 213. The connection between the platform module assembly 11 and the column assembly 21 is mainly formed by installing a countersunk hexagon socket screw 9 between the end surface connection plate 211 and the end surface connection plate 1 111 to form a fixed connection. The upper end surface of the end surface connection plate 211 is pressed against the lower end surface of the end surface connection plate 1 111, and the countersunk hexagon socket screw 9 is used to bury the head into the two end surfaces to fix the column assembly 2 and the platform module assembly 11. The head of the countersunk hexagon socket screw 9 can be buried in the component, a large torque can be applied, and the connection strength is high, which can replace the hexagonal bolt. It is suitable for joints that require a compact structure and a smooth appearance.

[0072] Position and install the support assembly 2 at the workplace, fit the bottom plate to the ground, insert the expansion screws 12 or screws 10 to fix the column assembly 21. After all the column assemblies 21 are fixed, the support assembly 2 is fixed. The column 212 is made of 8080 aluminum profile, which is suitable for ultra-high stress and ultra-high strength frame structures and can withstand loads far greater than ordinary steel structures. The fixed platform module 1 is arranged on the fixed support assembly 2, and the overall frame of the assembly work platform of this embodiment is formed.

[0073] The ladder module 4 is a single-flight staircase comprising steps and a steel frame. The ladder module 4 includes two types: a hanging ladder module 41 and a step ladder module 42. Figure 7 As shown, the upper end of the ladder module 41 is provided with an adapter 411, and the adapter 411 is fixedly connected to the end of the platform module 1 by screws 10, as shown in FIG. Figure 8 As shown, a sliding member 421 is provided at the bottom of the step ladder module 42, and the step ladder module 42 is arranged below the end of the platform module 1. The adapter 411 is not freely rotatable at any angle, and its rotation angle is between 45°-135°. On the basis of the above, when the height of the hanging ladder module 41 is 2000mm and the step width is 600mm, it is more convenient to walk.

[0074] like Figure 6 As shown, the guardrail 3 is a quadrilateral structure with a metal solid frame on all sides and a plate fixed in the center of the frame. The guardrail 3 includes a horizontal guardrail 31 and an oblique guardrail 32. The difference between the two is that the four corners of the horizontal guardrail 31 are right angles, and the four corners of the oblique guardrail 32 are two acute angles and two obtuse angles. The metal solid horizontal frame 311 and the oblique frame 321 of the guardrail 3 are still made of 4040 aluminum profiles, and the baffle 1 312 and baffle 2 322 are made of transparent PC board. The PC board is impact-resistant, has high toughness, good heat and cold resistance, strong bending and tensile strength, good dimensional stability, wear resistance, corrosion resistance, and high transparency. Compared with acrylic boards of the same material, the performance is more superior. At the same time, a U-shaped clamping seal is built into the connection between the plate and the frame to make the connection more secure. The horizontal guardrail 31 is arranged on both sides of the horizontal area of ​​the platform module 1, and the column base 1 313 arranged below the horizontal guardrail 31 is fitted with the edge of the platform module 1 and fixed with screws 10. The oblique guardrail 32 is arranged on both sides of the inclined area of ​​the platform module 1 and both sides of the trapezoidal module 4, and the column base 2 323 arranged below the oblique guardrail 32 is fitted with the edge of the platform module 1 and fixed with screws 10. Similarly, the column base 2 323 is fitted with both sides of the trapezoidal module 4 and fixed by screwing with screws 10.

[0075] like Fig. 9 As shown, the plate-type limiter 5 includes a countersunk hole 51, a screw hole 52 and a groove 53. The plate-type limiter 5 is a connecting unit between the fixed platform module 1 and the extension block module 6. The types of the extension block module 6 include a hanging extension block 61, an upward-flipping extension block 62 and a downward-flipping extension block 63. The extension block module 6 is provided with a connecting fixture 600, a rigid frame 601, an extension block module surface layer 602 and a safety strip 603. The connecting fixture 600 fixes the extension block module 6 on the plate-type limiter 5, the rigid frame 601 is mainly used for the connection between the extension block module 6 and the slat assembly 72, the extension block module surface layer 602 extends the flat platform working area, which is convenient for assembling tooling, and the safety strip 603 plays a protective role. The extension block module 6 is mainly to expand the actual working process, due to the problem of the distance between the built platform and the working area being too long, to supplement, increase the area of ​​the specific area of ​​the platform module 1, and facilitate installation and disassembly.

[0076] like Fig.10 As shown, the connecting fixture 600 in the hanging extension block 61 is in the form of a hook 611, which is suitable for scenes where it cannot be flipped up and down; Fig.11 As shown, the connecting fixing member 600 in the upward extension block 62 is in the form of an upward hinge 621, which is suitable for the scene where the product needs to be flipped up and avoided when being put on and off the shelf; Fig.12As shown, the connecting fixing member 600 in the downward-flipping extension block 63 is in the form of a downward-flipping hinge 631, which is suitable for the scenario where the product needs to be flipped down to avoid being put on or put off the shelf. Fig.13 As shown, the hinged form of the downward hinge 631 is that the two cylindrical heads protruding from the slide bar 6-01 are movably connected to the slide bar hole 6-02. When the downward hinge 631 is flipped downward, the slide bar 6-01 slides from the upper end to the lower end of the slide bar hole 6-02.

[0077] like Fig.14 As shown, the connecting fixture 600 is used for the fixed connection between the extension block module 6 and the plate-type stopper 5. The extension block module 6 is positioned and matched with the plate-type stopper 5. The connecting fixture 600 has a rectangular through hole, and the screw hole 52 is aligned with the rectangular through hole and then screwed and fixed with a screw 10.

[0078] The custom part 7 module includes a transition platform assembly 71 and a strap assembly 72. The transition platform assembly 71 is arranged at the connection gap between two adjacent platform module assemblies 11. Fig.15 As shown, the transition platform assembly 71 has various forms, and its overall form can be triangular or square. The transition platform 71 is made of a composite anti-skid wooden board and a frame connected by countersunk hexagon socket screws, and its frame material can still be aluminum profiles. Fig.17 As shown, when there is a gap at the connection between the step plane components 11 in the platform module 1 due to factors such as corners or improper connection, a transition step component 71 is arranged at the gap. The transition step frame 712 of the transition step component 71 fits the edge side of the step plane component 11 and is fixed with a countersunk hexagon socket screw 9. After fixing, the transition step surface layer 711 is flush with the upper plane of the step plane component 11.

[0079] A strap assembly 72 is arranged between the extension block modules 6. Figure 1 and Fig.17 As shown, since a truss 15 needs to be arranged between the base module 14 and the frame column module assembly 13 to connect the two, when assembling the tooling, it is necessary to work near the frame column module assembly 13. Since the upper surface of the platform module assembly 11 is a rectangular plane, it cannot be well adapted to the frame column module assembly 13 of different sizes in different scenes. Therefore, an extension block module 6 is arranged on the side of the platform module 1 close to the working area to facilitate the work.

[0080] But in fact, the assembly tool is not only for one direction, so a strap assembly 72 is set between the extension block modules 6 to compensate for the gaps generated by the frame column module assembly 13. The strap assembly 72 is set, and an L-shaped fixing piece 721 is provided on the strap assembly 72 to be adapted and connected with the rigid frame 601. The L-shaped fixing piece 721 is a steel fixing piece, which can be specifically an L-shaped angle steel 721, and the rigid frame 601 can still be made of an aluminum profile frame. If there are gaps between the extension block modules 6, the strap assembly 72 is arranged between the extension block modules 6, and the L-shaped angle steel 721 is fitted with the aluminum profile frame 601 and fixedly connected using screws 10.

[0081] Beneficial effects of this embodiment: This embodiment describes a modular, reconfigurable, adaptive assembly work platform, in which the platform module includes a plurality of tower units, and the step module assembly 11, the column module 2, and the remaining modules of the assembly platform are all large modules for assembly, and only modularization and standardization are required, and there is no excessive requirement for size. Therefore, the assembly platform module is simple to manufacture, and the platform quality is easy to control. Since the platform module 1 includes a plurality of tower units, the plurality of tower units and the modules are adapted to form an integral platform, but in fact, due to the independence of the tower unit, the modules that cooperate with it are actually also independent, and the independent modules can be coordinated with the actual working environment, and have strong reconfigurability.

[0082] Example 2

[0083] like Figure 1-19 As shown, this embodiment describes a modular reconfigurable adaptive assembly work platform assembly method for embodiment 1, comprising the following steps:

[0084] Step S0: Analyze the overall working environment to determine the platform position and the height of the working platform; the assembly platform of this embodiment will be used to build a base for assembly tools in the future, and the assembly tools need to arrange reference points around the tools according to the "maximum encirclement principle" as the reference for establishing the coordinate system of the entire tooling. Therefore, calculations are performed at specific locations to determine the position of the support assembly, in order to facilitate the later assembly of the tools.

[0085] Step S1: Position the support assembly 2, and use expansion screws 11 to fix the column assembly 21 at the platform positioning location on the bottom plate 213 of the column assembly 21. Determine the number of platform module assemblies 11 required, and a number of platform module assemblies 11 form a plurality of tower units, which are arranged above the adapted support assembly 2, and a plurality of tower units form a flat platform 1; set the platform module 1 above the support assembly 2: fit the end surface connection plate 1 111 and the end surface connection plate 2 211 together, and use countersunk hexagon socket head screws 9 between the bottom of the end surface connection plate 1 111 and the upper surface of the end surface connection plate 2 211 to fix the two.

[0086] Step S2: Set the ladder module 4 at one or both ends of the platform module 1. Set the ladder module 41, the adapter 411 and the port of the platform module 1, find a through hole on the adapter 411, the adapter 411 can be rotated, rotate the adapter 411 to fit the port of the platform module 1, set the screw 10 from the through hole to fix the two; set the step ladder module 42, the step ladder module 42 is set below the port of the platform module 1, use the sliding member 421 below the step ladder module 42 to push the step ladder module 41 to the port of the platform module 1, and fix the sliding member 421.

[0087] Step S3: Arrange guardrails 3 on both sides or one side of the platform module 1, oblique guardrails 32 on both sides or one side of the tower unit 1-a, horizontal guardrails 31 on both sides or one side of the tower unit 2 1-b, and oblique guardrails 32 on both sides of the trapezoidal module 4; fit the column base 1 313 set below the horizontal guardrail 31 to the edge of the platform module 1 and fix it with screws 10. Oblique guardrails 32 are set on both sides of the trapezoidal module 4, and column base 2 323 is set below the oblique guardrail 32. The bottom of the column base 2 323 is connected to the platform module 1 with screws 10;

[0088] Step S4: Set the plate-type stopper 5 on one side of the working area of ​​the platform module 1, and fit the countersunk hole 51 to one side of the platform module 1. Use the countersunk hexagon socket screw 9 to fix the two surfaces. Position the extension block module 6 and the plate-type stopper 5, and fix them. There is a rectangular through hole on the connection fixing piece 600. After the screw hole 52 is aligned with the rectangular through hole, fix them with the screw 10.

[0089] Step S5: Check whether there is a gap between the connection of the platform module 1 and the extension block module 6, and if there is a gap, set the custom part 7. Check whether there is a gap at the connection of the platform module assembly 11 in the platform module 1, and if there is a gap, arrange the transition platform assembly 71 at the gap, and the aluminum profile frame of the transition platform assembly 71 fits the edge side of the platform plane assembly 11, and is fixed with a countersunk hexagon socket screw 9; if there is a gap between the frame column module assemblies 13, set the board assembly 72 between the extension block modules 6, and fit the L-shaped angle steel 721 with the aluminum profile frame 601 and fix it with screws 10.

[0090] More specifically, Figure 2 As shown, a heightening member 8 can also be installed under the modular reconfigurable adaptive assembly work platform. Fig.19 As shown, the heightening component 8 includes a first-order heightening component 81, a second-order heightening component 82, and a third-order heightening component 83, which are used for material transportation during assembly of tooling.

[0091] Beneficial effects of this embodiment: This embodiment describes a modular reconfigurable adaptive assembly work platform assembly method. Since the assembly components of the assembly platform are all modular and standardized components, they can be assembled on site, with extremely high adaptability and no need for customization in advance. Several step module assemblies 11 form multiple tower units, and multiple tower units are unified into a platform module 1, but each tower unit is independent of each other, so each tower unit is self-contained, and each tower unit can be disassembled and installed separately, with extremely high reconfigurability, and each component of the platform only needs to meet the requirements of standardization and modularization, and the requirements for dimensional accuracy are relatively low, so it is easier to manufacture and the quality of the platform is easy to control.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
