Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft structural parts processing, and in particular relates to a flexible tooling for aircraft structural parts. Background Art

[0002] Flexible tooling for aircraft structural parts is a tooling system designed for the manufacture of large and complex aircraft structural parts. It has the characteristics of high flexibility, high precision, and high efficiency, and can adapt to the manufacturing needs of aircraft structural parts of different shapes, sizes, and structural characteristics.

[0003] In the prior art, there is a flexible tooling for aviation structural parts with patent announcement number CN218427892U. The above patent fixes the structural parts by placing them on the limiting mechanism, fixing the spatial position of the structural parts by the limiting mechanism, and then resetting the pins of the pin-type flexible mechanism. During the resetting process, the pins will resist the supporting surface of the structural parts, thereby matching the outer shape of the structural parts, and finally locking the pins to form a supporting station. In this way, the simple structure can be fixed by the limiting mechanism, and then the pins of the pin-type flexible mechanism can be reset to match the outer shape of the structural parts without pressing down, so as to better fix the position of the pins, and then match the subsequent processing of the structural parts. However, there are still the following deficiencies in actual use: from a practical point of view, when fixing the position of the structural parts, it is necessary to adjust the various components in the limiting mechanism to fix the structural parts. The structure is relatively complicated and inconvenient to operate, which reduces the usability of the tooling. At the same time, the flexible tooling is inconvenient to move and has poor practicality.

[0004] Therefore, there is a need for a flexible tooling for aircraft structural parts to solve the problems in the prior art that the limiting mechanism structure is relatively complicated, inconvenient to operate and inconvenient to move. Utility Model Content

[0007] The limiting mechanism consists of a fixed block, a vertical plate, a cylinder, a U-shaped block, a first fixed shaft, a first rotating block, a placement plate, a rotating vertical plate, a second fixed shaft, a second rotating block, a rotating plate and a limiting ball.

[0011] As a preferred embodiment, the moving mechanism consists of a fixed seat, an electric push rod, a moving plate, a slider and a universal wheel.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0023] The limiting mechanism 3 is composed of a fixed block 301, a vertical plate 302, a cylinder 303, a U-shaped block 304, a first fixed shaft 305, a first rotating block 306, a placement plate 307, a rotating vertical plate 308, a second fixed shaft 309, a second rotating block 310, a rotating plate 311 and a limiting ball 312. The fixed block 301 is rollingly connected to the upper part of the interior of the bottom plate 1, the vertical plate 302 is symmetrically fixedly connected to the upper part of the fixed block 301, the cylinder 303 is fixedly connected to the upper part of the interior of the fixed block 301, the U-shaped block 304 is connected to the upper part of the output end of the cylinder 303, the first fixed shaft 305 is fixedly connected to the inside of the U-shaped block 304, the first rotating block 306 is rotatably connected to the outside of the first fixed shaft 305, and the second fixed shaft 309 is fixedly connected between the vertical plates 302.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth to explain in detail that a through slot matching with the U-shaped block 304 is opened inside the first fixed shaft 305, and the U-shaped block 304 is slidably connected inside the through slot;

[0025] The U-shaped block 304 is driven downward by controlling the air cylinder 303, and the placement plate 307 is driven downward at the same time, so that the fixed structural parts can be removed easily after the operation is completed.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the placement plate 307 is fixedly connected to one side of the first rotating block 306 , and the rotating vertical plate 308 is fixedly connected to the top of the first rotating block 306 .

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the second rotating block 310 is rotatably connected to the outside of the second fixed shaft 309, the limiting ball 312 is fixedly connected to one side of the second rotating block 310, and the rotating plate 311 is fixedly connected to the other side of the second rotating block 310;

[0028] The structural member is placed above the placement plate 307, and the first rotating block 306 rotates to drive the rotating vertical plate 308 to push the rotating plate 311, and the second rotating block 310 rotates to drive the limiting ball 312 to move downward to limit the top surface of the structural member and fix the position of the structural member.

[0029] According to the above working process, it can be known that: through the setting of the limiting mechanism 3, when the structural part is placed on the placement plate 307, the upper limiting ball 312 is driven to move downward to limit the top surface of the structural part, thereby fixing the position of the structural part. The structure is simple and the operation is convenient, thereby improving the usability of the flexible tooling.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the moving mechanism 2 is composed of a fixed seat 201, an electric push rod 203, a moving plate 204, a slider 205 and a universal wheel 206. The fixed seat 201 is fixedly connected to the bottom surface of the base plate 1, the top surface of the electric push rod 203 is fixedly connected to the bottom surface of the base plate 1, the moving plate 204 is fixedly connected to the bottom of the electric push rod 203, and the universal wheel 206 is symmetrically fixedly installed below the moving plate 204.

[0031] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth to explain in detail that the interior of the fixed seat 201 is symmetrically provided with a slide groove 202, the sliders 205 are symmetrically fixedly connected to the two sides of the movable plate 204, and the sliders 205 are slidably connected to the interior of the slide groove 202;

[0033] The pin-type flexible mechanism 4 is described in detail in the utility model with patent announcement number CN218427892U, and will not be described in detail here.

[0034] This scheme has the following working process: when in use, the tooling is moved to the required position through the universal wheel 206 at the bottom, and then the electric push rod 203 is controlled to drive the moving plate 204 to move up, and the universal wheel 206 is driven to move up until the bottom surface of the universal wheel 206 is higher than the bottom surface of the fixed seat 201. At this time, the tooling is placed on the ground through the fixed seat 201 to ensure the stability of the tooling when in use; then the structural part is placed above the placement plate 307, and the first rotating block 306 is rotated to drive the rotating vertical plate 308 to push the rotating plate 311, and the second rotating block 310 is rotated to drive the limiting ball 312 to move downward, limit the top surface of the structural part, fix the position of the structural part, and then support the middle part of the structural part through the pin-type flexible mechanism 4, and perform processing operations on the structural part. After the operation is completed, the cylinder 303 is controlled to drive the U-shaped block 304 to move downward, and at the same time drive the placement plate 307 to move downward, so as to facilitate the removal of the structural part.

[0035] In summary: through the setting of the limiting mechanism 3, when the structural part is placed on the placement plate 307, the upper limiting ball 312 is driven to move downward to limit the top surface of the structural part, thereby fixing the position of the structural part. The structure is simple, the operation is convenient, and the usability of the flexible tooling is improved. Through the setting of the moving mechanism 2, the flexible tooling as a whole can be easily moved to the position required for operation, and can also be placed on the ground through the fixed seat 201, thereby ensuring the stability of the tooling during use and improving the practicality of the tooling.
