Description

Technical Field

[0001] This utility model relates to the field of fuselage frame mold technology, and more specifically, to a fixing device for manufacturing fuselage frame molds. Background Technology

[0002] Aircraft fuselage molds are critical process equipment in aircraft manufacturing, characterized by their complex structure, large size, and extremely high precision requirements. The fixing devices used to manufacture these molds serve the core function of providing precise and rigid positioning and clamping for the various components of the mold during machining, inspection, and assembly. This is fundamental to ensuring the final manufacturing accuracy of the mold and, consequently, the accuracy of the assembly of aircraft fuselage parts. The positioning accuracy, structural stability, and ease of operation of these fixing devices directly determine the manufacturing quality and efficiency of the mold.

[0003] However, the existing fixing device can only process one side. When it is necessary to process or measure other sides or top surfaces of the mold, the mold needs to be flipped over as a whole. This process relies on the cooperation of multiple operators, which is time-consuming and labor-intensive. Moreover, the mold is easily damaged during frequent lifting and flipping. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for manufacturing fuselage frame molds, which addresses the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a fixing device for manufacturing a frame mold, including a base, a worktable fixedly connected to the top of the base, two first lead screws extending coaxially in the worktable, a movable seat relative to the first lead screws on the worktable, a first threaded seat at the bottom of the movable seat, the first threaded seat passing through a first connecting groove on the worktable to engage with the corresponding first lead screw to drive the movable seat to move respectively; A flipping box is provided on the movable base. A rotating plate is rotatably connected to the working end of the flipping box. A clamping seat is fixedly connected to the other side of the rotating plate. The clamping seat is used to hold the mold. One of the tilting boxes is equipped with a drive device for driving the rotating plate to rotate; A support platform is provided on the top of the workbench and between the two clamping seats, and the bottom of the support platform is connected to the workbench via a lifting seat.

[0006] Optionally, the worktable is provided with two slide grooves, which are located on both sides of the first connecting groove and extend in the same direction as the first connecting groove. The movable seat is provided with a slider corresponding to the position of the slide groove, and the slider slides within the slide groove.

[0007] Optionally, the clamping seat has a hollow structure inside, and the clamping seat is provided with a plurality of clamping groups, the clamping groups including a plurality of clamping elements; The clamping component includes at least two coaxially arranged second lead screws. Clamping blocks are respectively provided on the outer side of the clamping seat opposite to the second lead screws. A second threaded seat is provided on the side of the clamping block near the clamping seat. The second threaded seat passes through a second connecting groove on the clamping seat and engages with the second lead screw. The extension direction of the second connecting groove is consistent with the axial direction of the second lead screw. The two second lead screws drive the corresponding clamping blocks to move in a direction that approaches / moves away from each other to clamp / release the mold. In the same clamping group, several clamping members are distributed along a direction perpendicular to the axis of the second lead screw.

[0008] Optionally, the clamping block is detachably connected to the second threaded seat. A screw is provided on the side of the clamping block near the second threaded seat, and the threaded seat is provided with a threaded hole for the screw to be screwed in axially to achieve locking, so that the clamping block and the threaded seat are threadedly connected.

[0009] Optionally, two slide rods are symmetrically arranged on the outside of the clamping seat and on one side of the clamping surface of each clamping block. One end of each slide rod passes through the clamping block and is fitted with a baffle. The other end of each slide rod is fitted with a pressure plate. A spring is sleeved on the slide rod, and the two ends of the spring are respectively connected to the opposite surfaces of the clamping block and the pressure plate.

[0010] Optionally, the pressure plate has a gasket on its surface that contacts the mold.

[0011] The fixing device for manufacturing fuselage frame molds provided by this utility model has the following beneficial effects: 1) Multi-angle processing of molds is achieved, significantly improving work efficiency. By setting a rotating box with a rotating plate on the moving base and equipping it with a drive device, the mold clamped on the clamping base can be rotated controllably around an axis. When it is necessary to operate on the side or top surface of the mold, there is no need to remove the mold from the device for overall hoisting and flipping. Simply drive the rotating plate to change the processing posture of the mold, avoiding the tedious and time-consuming process, shortening the changeover time between processes, and thus greatly improving manufacturing and inspection efficiency.

[0012] 2) It enhances operational convenience and safety, reduces labor intensity and reliance on manual labor, and effectively avoids potential damage to the mold during frequent lifting and turning. Traditional overall turning requires multiple operators to cooperate in lifting, which poses safety risks and is labor-intensive. This device achieves mechanized mold turning through a built-in drive mechanism. Operators only need to control the drive mechanism to complete the posture adjustment, making operation simple and labor-saving, reducing reliance on skilled workers and multiple people working together, and also reducing the risk of personal injury that may be caused by manual handling and turning.

[0013] 3) It provides flexible and adjustable clamping and support, offering strong adaptability. Two movable seats that can move independently along the first lead screw allow for precise adjustment of the distance between the two clamping seats via lead screw transmission, thus accommodating the clamping requirements of molds of different sizes. Simultaneously, a height-adjustable support platform is located in the middle of the worktable, providing additional, height-adjustable auxiliary support at the bottom of the mold. Especially for large or long molds, this design effectively enhances clamping rigidity, preventing deformation or vibration caused by excessive overhang during processing, and improving processing stability.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0018] like Figure 1 and Figure 2 As shown, this application embodiment provides a fixing device for manufacturing a fuselage frame mold, including a base 10, a worktable 11 fixedly connected to the top of the base 10, two coaxial first lead screws 14 disposed inside the worktable 11, a movable seat 21 relative to the first lead screws 14 disposed on the worktable 11, a first threaded seat 25 disposed at the bottom of the movable seat 21, the first threaded seat 25 passing through a first connecting groove 12 on the worktable 11 to engage with the corresponding first lead screw 14, so as to drive the movable seat to move along the first lead screw 14 respectively; a flipping box 20 disposed on the movable seat 21, a rotating plate 22 rotatably connected to the working end of the flipping box 20, a clamping seat 40 fixedly connected to the other side of the rotating plate 22, the clamping seat 40 being used to hold the mold; a driving device disposed inside one of the flipping boxes 20, used to drive the rotating plate 22 to rotate; a support platform 50 disposed on the top of the worktable 11 and located between the two clamping seats 40, the bottom of the support platform 50 being connected to the worktable 11 via a lifting seat 51. In use, first place the mold on the support platform 50, adjust the distance between the two movable seats 21 so that the clamping seats 40 are aligned with both ends of the mold, and then fix the mold with the clamping seats 40. When processing different surfaces, start the drive motor 26 to rotate the mold to the required angle, and the support platform 50 can be raised to provide auxiliary support.

[0019] like Figure 4As shown, one of the flip boxes 20 contains a servo motor 26 as a drive device to drive the rotating shaft 23 of the rotating plate 22 to rotate.

[0020] This application utilizes two movable seats 21 and a tilting box 20 with a built-in drive device 26. After clamping, the mold can be controlled to rotate axially without disassembly, easily adjusting different sides or top surfaces to the processing position. This avoids the cumbersome process of traditional hoisting and tilting, shortening the preparation time. The mold is securely fixed to the device throughout the entire processing, and all posture changes are completed on the device, preventing bumps, scratches, or deformation that may occur during hoisting and transportation, thus protecting the integrity of the high-precision mold. The two movable seats 21 can be precisely adjusted in distance along the first lead screw 14 according to the mold length, achieving adaptive clamping. The independent lifting support platform 50 located in the middle of the worktable 11 provides stable auxiliary support for the mold, especially the middle of long molds, effectively suppressing vibration and deformation during processing and ensuring processing accuracy.

[0021] Specifically, such as Figure 3 As shown, the worktable 11 is provided with two sliding grooves 13, which are located on both sides of the first connecting groove 12 and extend in the same direction as the first connecting groove 12. The movable seat 21 is provided with a slider 24 corresponding to the position of the sliding groove 13, and the slider 24 slides within the sliding groove 13. This provides a double-track guide for the linear movement of the movable seat 21, enhances the stability during the movement process, prevents the movable seat 21 from jamming or shifting when carrying heavy molds, and ensures the accuracy of the movement positioning.

[0022] Specifically, such as Figure 5 and Figure 6 As shown, the clamping base 40 has a hollow internal structure and contains several clamping groups, each including several clamping components. Each clamping component includes at least two coaxially arranged second lead screws 43. Clamping blocks 30 are respectively arranged on the outer side of the clamping base 40 opposite to the second lead screws 43. A second threaded seat 42 is provided on the side of the clamping block 30 near the clamping base 40. The second threaded seat 42 passes through a second connecting groove 41 on the clamping base 40 and engages with the second lead screw 43. The extension direction of the second connecting groove 41 is consistent with the axial direction of the second lead screw 43. The two second lead screws 43 drive the corresponding clamping blocks 30 to move in a direction closer to / away from each other to clamp / release the mold. In the same clamping group, several clamping components are distributed along a direction perpendicular to the axis of the second lead screw 43. This allows for multi-point opposing clamping of the mold. By rotating a single second lead screw 43, a single clamping block 30 on it can be driven to move, thereby clamping or releasing the mold from both sides.

[0023] In this embodiment, the clamping group includes a first set of clamping groups distributed along a first direction and a second set of clamping groups distributed along a second direction, wherein the first and second directions are perpendicular to each other. In the figure, X indicates the first direction, and Y indicates the second direction. This design enables the formation of multiple clamping points on the clamping surface of the mold along the height direction, providing more uniform and comprehensive constraint forces for mold components with complex contours or large heights, effectively preventing instability during processing. Figure 5 As shown, the clamping groups inside the clamping seat 40 are distributed in two groups in the horizontal direction and one group in the vertical direction.

[0024] In one embodiment of this application, the clamping block 30 is detachably connected to the second threaded seat 42. Specifically, a screw is provided on the side of the clamping block 30 near the second threaded seat 42, and the threaded seat 42 has a threaded hole for the screw to be screwed in axially to achieve locking, so that the clamping block 30 and the threaded seat 42 are threadedly connected. The clamping block 30 and the second threaded seat 42 are connected by a screw. The operator can select a special clamping block 30 with different contact surfaces according to the specific shape of the mold, or remove the clamping block 30 and replace it by a simple screwing operation. This enhances the versatility and flexibility of the device, facilitates the individual replacement of the clamping block 30 after wear, and reduces maintenance costs.

[0025] Specifically, such as Figure 7 As shown, two slide rods 33 are symmetrically arranged on the outside of the clamping base 40 and on one side of the clamping surface of each clamping block 30. One end of each slide rod 33 passes through the clamping block 30 and is fitted with a baffle 32. The other end of each slide rod 33 is fitted with a pressure plate 31. A spring 34 is sleeved on the slide rod 33, and the two ends of the spring 34 are connected to the opposite surfaces of the clamping block 30 and the pressure plate 31, respectively. When the clamping block 30 moves toward the mold, the pressure plate 31 contacts the mold first, and the spring 34 is compressed, thereby absorbing the impact and adapting to minor unevenness. In the clamping state, the continuous elastic force of the spring 34 provides a flexible and buffered clamping force for the mold, which can effectively avoid indentations or damage to the precision surface of the mold caused by rigid over-positioning or machine tool vibration, and is especially suitable for molds with extremely high surface quality requirements.

[0026] In one embodiment of this application, a gasket is provided on the surface of the pressure plate 31 that contacts the mold. The gasket directly contacts the mold and is usually made of a softer elastic or non-metallic material. This can prevent the hard metal pressure plate 31 or the clamping block 30 body from causing indentations, scratches or abrasions to the finished surface of the mold when clamping. The surface of the gasket can be designed with a texture to increase friction or use a material with a high coefficient of friction, thereby providing greater static friction when in contact with the mold.

[0027] The usage process of this utility model is as follows: First, the machine frame mold to be processed is hoisted onto the lifting support platform 50 in the middle of the workbench 11. By controlling the first lead screw 14, the two moving seats 21 are driven to move towards each other, so that the clamping seats 40 on them are moved to suitable positions at both ends of the mold. Then, according to the shape and size of the mold, the type and position of the clamping blocks 30 on the clamping seats 40 can be selected or adjusted. By rotating the second lead screw 43 in each clamping component, the clamping blocks 30 on both sides are driven to move towards each other synchronously, so that the pressure plate 31 at the front end of the clamping block 30 and its upper part are moved towards the appropriate positions. The protective pads contact the mold sidewalls, achieving multi-point, flexible, and stable clamping under the buffering effect of the spring 34. When other surfaces of the mold need to be processed or inspected, the drive device 26 inside the tilting box 20 is activated to rotate the rotating plate 22 and the clamped mold as a whole to the required angle and lock it. During the process, the lifting support platform 50 can adjust its height as needed to continuously provide auxiliary support. After the operation of one surface is completed, the mold can be driven to rotate to a new work position again until all processing operations are completed. The entire process does not require disassembling the mold for hoisting and tilting.

[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
