Description

Technical Field

[0001] This invention relates to a highly flexible positioning and assembly device and method applicable to missile body panel-type compartments, belonging to the field of missile body assembly technology. Background Technology

[0002] Previously, panel-type structural modules were assembled using traditional manual riveting methods, which were labor-intensive, inefficient, and resulted in inconsistent riveting quality, failing to meet the demands of ever-increasing production. Furthermore, the varying heights of different panel-type modules required different sizes of riveting fixtures, consuming large areas and contradicting the principles of green economics. Figure 1 Traditional automated riveting systems for wall panel products mainly undertake the riveting and assembly tasks of wall panel structure cylinders and conical compartments of various sizes of missile bodies. However, the bracket and equipment of traditional riveting systems are integrated, and usually one automatic riveting machine is only applicable to one product. It has poor flexibility and can only adapt to a limited number of product types. When the position or shape of the wall panel changes, frequent manual intervention is required. At the same time, it is not possible to quickly change products on and off the shelf, which affects production efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned shortcomings and provide a highly flexible positioning and assembly device and method suitable for missile body panel-type compartments. This solves the technical problems of high labor intensity, low production efficiency, and poor consistency in riveting quality associated with traditional manual riveting methods for panel-type compartment products. This invention enables flexible and rapid positioning and efficient assembly of panel-type compartments, is compatible with the assembly of panel-type compartments of various sizes, and facilitates the engineering application of flexible automated drilling and riveting for various panel-type compartments. A schematic diagram of the automated riveting system for panel products is shown below. Figure 1 .

The rear process frame locking mechanism is used to lock the position of the rear process frame after it has been axially moved into place.

[0020] Furthermore, the central support includes a central support movable bracket, a central support horizontal clamp, and a central support locking mechanism;

Detailed Implementation

[0042] The features and advantages of the present invention will become clearer and more apparent from the following detailed description.

[0043] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0044] This invention discloses a highly flexible positioning and assembly device and its method for use in missile body panel-type compartments, enabling flexible, efficient, and automated assembly of panel-type structural compartments of different sizes. The assembly device of this invention works in conjunction with the drilling and riveting station of the automated riveting system for panel products via a configuration interface, achieving flexible and rapid positioning and efficient assembly of panel-type compartments. Axial movement of the central support allows for height (height direction is the product axis) positioning of various types of intermediate frames, thus ensuring compatibility with the assembly of panel-type compartments of multiple sizes and realizing the flexible and automated drilling and riveting engineering applications of various panel-type compartments.

[0045] This invention discloses a highly flexible positioning and assembly device suitable for missile body panel-type compartments, comprising multiple components: a retainer 1, a rear process frame 2, a central support 3, a bracket axial crossbeam 4, and a front process frame 5, as shown below. Figure 2 As shown.

[0046] like Figure 3 As shown, the cage 1 includes a support 1.1, an adapter bracket 1.2, and a fixing plate 1.3. The support 1.1 has open claw-shaped ends and is connected to the adapter bracket 1.2 via conical pins and hexagonal head screws. The lower end of the adapter bracket 1.2 is fixedly connected to the axial beam 4 of the bracket via pins and screws. The fixing plate 1.3 is fixedly connected to both the support 1.1 and the adapter bracket 1.2 via pins and screws, serving as an auxiliary connection. The cage 1 has high structural strength and rigidity, primarily functioning to maintain the overall shape of the assembly, thereby ensuring the dimensional and positional tolerances required after product assembly.

[0047] like Figure 4 As shown, the rear process frame 2 includes a rear process frame moving bracket 2.1, a rear process frame horizontal clamp 2.2, and a rear process frame locking mechanism 2.3. The rear process frame 2 can move flexibly along the component's axial direction via the guide rail mechanism on both sides of the bracket axial beam 4 to ensure the relative height of the upper and lower end frames of the product. Then, the rear process frame locking mechanism 2.3 is set to the locked state to fix the position of the rear process frame, meeting the positioning and assembly requirements of different types of products. The rear process frame horizontal clamp 2.2 can be used to achieve multi-point positioning and clamping of parts such as skins and stringers. Furthermore, by setting the rear process frame locking mechanism 2.3 to the unlocked state, different interface types of the rear process frame 2 can be quickly changed to ensure compatibility with the structural functional components such as product beams and joints, achieving flexible quick-change between different product heights and states.

[0048] like Figure 5As shown, the central support 3 includes a central support movable bracket 3.1, a wall panel support block 3.2, a middle frame positioning seat 3.3, a central support horizontal clamp 3.4, and a central support locking mechanism 3.5. The wall panel support block 3.2 is used for radial support of the wall panel structure composed of the skin and stringers. The middle frame positioning seat 3.3 can define the position of each middle frame of the wall panel. The movable bracket 3.1 is equipped with multiple interfaces for the wall panel support blocks 3.2 and the middle frame positioning seats 3.3, which can be adaptively added or removed according to different product heights and different numbers of middle frames. The central support horizontal clamp 3.4 is used for fixing and clamping the wall panel skin. Each central support 3 can be axially adjusted along the slide rail mechanism of the bracket axial beam 4. Then, the central support locking mechanism 3.5 is switched from the unlocked state to the locked state to complete the fixed positioning of the central support 3, ultimately realizing the support and positioning function of middle frames of various heights. The middle support 3 can also utilize quick-change interfaces to achieve quick disassembly of the support and non-support functions, reducing the interference area with the internal and external actuators of the automatic drilling and riveting system, so as to maximize the efficient assembly capability of automatic drilling and riveting for various products.

[0049] like Figure 6 As shown, the axial crossbeam 4 of the bracket includes a crossbeam 4.1, a slider 4.2, a guide rail 4.3, a pressure block 4.4, and positioning pads 4.5. The crossbeam 4.1 is fixedly connected to the bracket of the automated riveting system by pins and screws. Multiple positioning pads 4.5 provide auxiliary support between the two. The top of the crossbeam 4.1 is fixedly connected to the guide rail 4.3, forming a moving carrier for the middle support 3 and the rear process frame 2 together with the slider 4.2. The slider 4.2 has the advantages of simple structure, convenient installation, and high interchangeability. It can achieve smooth movement and precise positioning on the high-precision, high-straightness guide rail 4.3, meeting the requirements of repeated high-precision positioning of end frames and middle frames of various products. The pressure block 4.4 is installed on the base of the guide rail 4.3 to fix and press the guide rail, bringing it close to the side reference plane. This effectively eliminates serpentine bending, ensures the parallelism of the guide rail, and thus improves the accuracy and stability of the guide rail device, extending its service life.

[0050] like Figure 7 As shown, the front process frame 5 includes a fixed bracket 5.1 and a front process frame horizontal clamp 5.2. The front process frame 5 is fixedly connected to the axial beam 4 of the bracket by pins and screws, simulating the front frame parts, and mainly plays the role of shape-preserving support and simulated positioning. The horizontal clamp 5.2 can realize multi-point positioning and clamping of parts such as skin and stringers.

[0051] Working principle and usage of the device:

[0052] This highly flexible positioning and assembly device is fixedly connected to the brackets on both sides of the automated riveting system for wall panel products. Based on the structure and height of the product to be processed, the front process frame 5 is positioned and installed. The position and quantity of the middle support 3 are adjusted via the slide rail mechanism of the axial beam 4 of the bracket. A rear process frame 2 with a suitable positioning interface is selected and adjusted to the corresponding height. After product positioning is completed, the automated riveting system moves back and forth along the component's axial direction. The internal and external riveting actuators can achieve efficient hole making, denting, and riveting functions.

[0053] Example:

[0054] Step 1: Preparation

[0055] After the highly flexible positioning and assembly device is fixedly connected to the brackets on both sides of the automated riveting system for wall panel products, the relevant manufacturing resources for adjusting the device's status are prepared, including wrenches, lifting tools, positioning pins, cleaning agents, etc.

[0056] Step Two: Status Adjustment

[0057] Based on the structure and height of the product to be processed, position and install the front process frame 5. Select the rear process frame 2 with a suitable interface according to the product structure. Adjust it to the appropriate height mark position through the slide rail mechanism of the bracket axial beam 4. Then remove and install the excess middle support 3, and install and adjust the position of the wall panel support block and the middle frame positioning seat. After positioning, clamp it with horizontal clamps.

[0058] Step 3: Processing and Application

[0059] After the product positioning is completed, the automated riveting system moves back and forth along the component axis, and achieves efficient hole making, denting, riveting and other functions through the internal and external riveting actuators.

Those skilled in the art will understand that various equivalent substitutions, modifications, or improvements can be made to the technical solutions and embodiments of the present invention without departing from the spirit and scope of the invention, and all such modifications and improvements fall within the scope of the present invention.
