Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft skin parts transfer, specifically relating to a transfer vehicle for aerospace processing and manufacturing. Background Technology

[0002] Skin panels are components used in the aerospace industry to be riveted onto the surface of aircraft frames. To ensure the aerodynamic performance of the aircraft, skin panels are often irregularly curved surfaces. In existing technologies, after skin panels are formed in molds, they are often transported directly by hoisting. Factors such as swaying during hoisting and the hoisting position can cause instability or even deformation of the skin panels during transport. Therefore, how to provide comprehensive support and stable transport for skin panels with irregular curved surfaces is a pressing technical problem that needs to be solved.

[0003] To address the aforementioned technical problems, this utility model discloses a migration vehicle for aerospace processing and manufacturing. Utility Model Content

[0004] This utility model discloses a transfer vehicle for aerospace processing and manufacturing, which can smoothly and quickly transfer aerospace skin parts, while providing full support for the skin during the transfer process to effectively prevent skin deformation.

[0005] This utility model is achieved through the following technical solution: A transfer vehicle for aerospace processing and manufacturing includes a mobile vehicle body. A lifting device is provided on the top of the mobile vehicle body. A rotary table assembly is provided on the top of the lifting device. A conformal clamp is installed on the top of the rotary table assembly. The bottom of the conformal clamp is detachably connected to the top of the rotary table assembly. A support surface is provided on the top of the conformal clamp corresponding to the outer contour of the skin part. An edge fastener is provided at the edge of the support surface.

[0006] The mobile vehicle body facilitates the convenient movement of the conformal fixture to the workstation. A lifting device vertically adjusts the fixture's height, while a rotary table assembly rotates the fixture, allowing the support surface at its top to contact and adhere to the skin part to be transported. This conformal support surface supports the skin, preventing instability or deformation during transport. Edge fasteners at the support surface edges secure the skin, ensuring stability throughout the entire transport process.

[0007] To better realize this utility model, the conformal clamp further includes a base, a buffer airbag, and a conformal support mold. The bottom of the base is detachably connected to the top of the rotary table assembly. The conformal support mold is hinged to the top of the base via a tension rod. Several buffer airbags are arranged closely between the conformal support mold and the base. Edge fasteners are provided at the edge of the base corresponding to the edge of the skin.

[0008] To better realize this utility model, the top of the base is provided with a first hinge shaft, the bottom of the conformal support mold is provided with a second hinge shaft, and the two ends of the tension rod are respectively hinged to the first hinge shaft and the second hinge shaft.

[0009] To better realize this utility model, the edge fastener further includes a tensioning strap and a buckle. A plurality of tensioning straps are provided at the edge of the support surface, and a buckle is provided at one end of the tensioning strap. The buckle is fastened to the edge of the skin.

[0010] To better realize this utility model, a flexible lining strip is further provided on the contact surface between the buckle and the skin.

[0011] To better realize this utility model, the lifting device further includes a screw jack, a lifting platform, and a guide column. The guide column is located at the top edge of the moving vehicle body, and a guide rail is provided on the guide column. The edge of the lifting platform is slidably connected to the guide rail via a slider. A threaded sleeve is provided on the lifting platform, and the threaded sleeve is threadedly connected to the screw in the screw jack. A rotary table assembly is provided on the lifting platform.

[0012] To better realize this utility model, the rotary table assembly further includes a rotary table body, a rotary motor, a gear ring, and a drive gear. The bottom end of the rotary table body is provided with a rotating shaft, which is rotatably connected to the connecting hole on the lifting platform. The bottom end of the rotating shaft is fitted with a gear ring. The bottom of the lifting platform is equipped with a rotary motor, and the output shaft of the rotary motor is fitted with a drive gear, which meshes with the gear ring.

[0013] To better realize this utility model, furthermore, lifting feet are provided downward at the edge of the mobile vehicle body.

[0014] To better realize this utility model, a towing hook is further provided at one end of the mobile vehicle body.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention enables the mobile vehicle to quickly move the conformal clamp to the work area. Simultaneously, the height of the conformal clamp is adjusted by a lifting device, and the rotation angle of the conformal clamp is adjusted by a rotating table assembly, allowing the skin to fit snugly on the conformal support surface set on top of the conformal clamp. The support surface provides full support for the skin, and during the transfer process, the cooperation between the support surface and the edge fasteners secures the skin, ensuring the stability of the skin throughout the entire transfer process.

Detailed Implementation

[0018] Example 1: This embodiment describes a migration vehicle for aerospace processing and manufacturing, such as... Figure 1 and Figure 3 As shown, the device includes a mobile vehicle body 1, a lifting device 2 on the top of the mobile vehicle body 1, a rotating platform assembly 3 on the top of the lifting device 2, a conformal clamp 4 on the top of the rotating platform assembly 3, the bottom of the conformal clamp 4 being detachably connected to the top of the rotating platform assembly 3, a support surface on the top of the conformal clamp 4 corresponding to the outer contour of the skin part, and an edge fastener 5 at the edge of the support surface.

[0019] The bottom of the mobile vehicle 1 is equipped with traveling wheels and swivel casters for steering. The cooperation of the swivel casters and traveling wheels allows the mobile vehicle 1 to move flexibly under external traction, enabling it to quickly move the conformal clamp 4 to the work area. After the formed skin part is lifted out of the molding mold, the lifting device 2 raises the conformal clamp 4, reducing the height difference between the clamp 4 and the skin part. Then, the rotary table assembly 3 finely rotates the conformal clamp 4 while vertically lowering the skin part, gradually bringing it into contact with the conformal support surface at the top of the clamp 4. Once the skin part is in contact with the support surface, the lifting device 2 lowers to a safe height, and the support fasteners 5 at the edge of the support surface tighten and secure the edges of the skin part, achieving overall support and fixation. The mobile vehicle 1 can then be moved by an external tractor, ensuring the stable and safe transfer of the skin part. During the transfer, the conformal support surface provides comprehensive support to the skin, effectively preventing deformation.

[0020] Furthermore, the mobile vehicle body 1 is provided with lifting support columns 6 at its edge. After the mobile vehicle body 1 moves to the working area, the lifting support columns 6 descend to contact the ground, supporting the mobile vehicle body 1 and ensuring its stability. During the movement of the mobile vehicle body 1, the lifting support columns 6 rise to lift off the ground without affecting the movement of the mobile vehicle body 1.

[0021] Furthermore, one end of the mobile vehicle body 1 is provided with a towing hook, which is used to easily connect with an external towing vehicle, so that the mobile vehicle body 1 can be moved by the external towing vehicle.

[0022] Example 2: This embodiment discloses a transfer vehicle for aerospace processing and manufacturing, which is an improvement on embodiment 1, such as... Figure 2 and Figure 4 As shown, the conformal clamp 4 includes a base 41, a buffer airbag 42, and a conformal support mold 43. The bottom of the base 41 is detachably connected to the top of the rotary table assembly 3. The conformal support mold 43 is hinged to the top of the base 41 via a tension rod. Several buffer airbags 42 are arranged closely between the conformal support mold 43 and the base 41. Edge fasteners 5 are provided at the edge of the base 41 corresponding to the edge of the skin.

[0023] The bottom of the base 41 is fixedly connected to the positioning groove on the top of the rotary table assembly 3 via a connecting flange. The connecting flange has several connecting holes circumferentially arranged, and the bottom surface of the positioning groove has several threaded holes circumferentially arranged. By screwing connecting screws into the aligned connecting holes and threaded holes, the base 41 is fixedly installed on the top of the rotary table assembly 3. Tension rods are provided at the top and edges of the base 41. One end of the tension rod is hinged to the base 41, and the other end of the tension rod is hinged to the bottom of the conformal support mold 43. The tension rods support the conformal support mold 43, and the extension and retraction of the tension rods accommodate the movement of the conformal support mold 43 during the lifting and covering process. Several buffer airbags 42 are also provided between the conformal support mold 43 and the base 41. During the hoisting of the skin parts, the inflation volume of each buffer airbag 42 is adjusted in real time according to the movement position of the conformal support mold 43 and the fit between the skin and the support surface. The buffer airbags 42 provide auxiliary support and force buffer for the conformal support mold 43 to avoid skin deformation.

[0024] Furthermore, a first hinge pin 100 is provided at the top of the base 41, and a second hinge pin 200 is provided at the bottom of the conformal support mold 43. The two ends of the tension rod are respectively hinged to the first hinge pin 100 and the second hinge pin 200. The number and position of the first hinge pin 100 and the second hinge pin 200 are set according to the actual shape of the skin to be hoisted. In particular, for sections with large changes in skin curvature, tension rods and buffer airbags 42 are added for auxiliary support.

[0025] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0026] Example 3: This embodiment discloses a migration vehicle for aerospace processing and manufacturing, which is optimized based on embodiment 1 or 2, such as... Figure 1 and Figure 4 As shown, the edge fastener 5 includes a tensioning strap 51 and a buckle 52. Several tensioning straps 51 are provided at the edge of the supporting surface, and a buckle 52 is provided at one end of each tensioning strap 51. The buckle 52 is fastened to the edge of the skin. The tensioning straps 51 are tied to the lugs at the edge of the supporting surface. After the skin is placed on the supporting surface, the buckle 52 is fastened to the edge of the skin, and the tensioning straps 51 are tightened with an appropriate tension force, so that the buckle 52 stably fastens and fixes the edge of the skin.

[0027] Furthermore, a flexible liner is provided on the contact surface between the buckle 52 and the skin. The flexible liner is made of materials such as foam and rubber to avoid rigid contact between the buckle 52 and the edge of the skin, thereby avoiding damage to the edge of the skin.

[0028] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0029] Example 4: This embodiment discloses a transfer vehicle for aerospace processing and manufacturing, which is an improvement on any one of embodiments 1-3, such as... Figure 3 As shown, the lifting device 2 includes a screw jack 21, a lifting platform 22, and a guide column 23. The guide column 23 is located at the top edge of the moving vehicle body 1, and a guide rail is provided on the guide column 23. The edge of the lifting platform 22 is slidably connected to the guide rail by a slider. A threaded sleeve is provided on the lifting platform 22, and the threaded sleeve is threadedly connected to the screw in the screw jack 21. A rotary table assembly 3 is provided on the lifting platform 22.

[0030] When the screw in the screw jack 21 rotates under the drive of the motor, it can drive the threaded sleeve and the lifting platform 22 to move vertically along the guide rail. The sliding cooperation between the guide rail and the slider guides the lifting platform 22, so that the lifting platform 22 moves smoothly in the vertical direction.

[0031] like Figure 3 As shown, the rotary table assembly 3 includes a rotary table body 31, a rotary motor 32, a gear ring 33, and a drive gear 34. The bottom end of the rotary table body 31 is provided with a rotating shaft, which is rotatably connected to the connecting hole on the lifting platform 22. The bottom end of the rotating shaft is fitted with a gear ring 33. The bottom of the lifting platform 22 is equipped with a rotary motor 32, and the output shaft of the rotary motor 32 is fitted with a drive gear 34, which meshes with the gear ring 33.

[0032] The rotary motor 32 drives the drive gear 34 to rotate, which in turn drives the gear ring 33 and the turntable body 31 to rotate. The rotation of the turntable body 31 realizes the rotation of the conformal fixture 4.

[0033] Preferably, the tooth ratio between the gear ring 33 and the drive gear 34 is 30:1-50:1.
