Description

Technical Field

[0001] This utility model relates to the field of aerospace parts processing technology, and in particular to a fixed tooling for aerospace parts processing. Background Technology

[0002] Aerospace parts machining mainly refers to the manufacturing of various aircraft components, including aircraft fuselage parts, aero-engine parts and accessories. Before machining aerospace parts, fixing devices are needed to secure them to ensure stability during machining and thus ensure the accuracy of the machined dimensions.

[0003] Patent CN216939452U discloses a quick-fixing device for machining aerospace parts, including a mounting component. The mounting component is a regular polyhedral annular structure. A rectangular through-hole is formed at the center of each outer face of the mounting component. Vertical grooves are formed on the two inner walls of the rectangular through-holes. Sliding adjustment plates are connected to each rectangular through-hole. Sliding blocks that cooperate with the grooves are connected to both sides of the adjustment plates. Fixing components for fixing parts are connected to each adjustment plate. A movable plate for supporting the parts is provided inside the mounting component. After the aerospace parts are placed inside the mounting component, the multiple movable plates can press against the aerospace parts to fix them.

[0004] Some aerospace parts require multiple flipping during manufacturing to ensure that all their outer walls are machined correctly, and the installation angle also needs to be adjusted as needed. However, once the aerospace parts are installed in the aforementioned fixing device, they cannot be flipped or their angle adjusted, resulting in insufficient fixing functionality.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This application discloses a fixed fixture for machining aerospace parts, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mounting base 1, a mounting frame 2 mounted on the mounting base 1, and a rotating frame 3 rotatably mounted on the mounting frame 2. The rotating frame 3 has a horizontal axis of rotation. Both ends of the rotating frame 3 extend outward from the mounting frame 2 and are connected to wheels 4. The mounting base 1 has a first limiting member 5 for restricting the rotation of the rotating frame 3. A limiting frame 6 is coaxially rotatably connected to the inner side of the rotating frame 3, and a second limiting member 7 is provided on the rotating frame 3 for restricting the rotation of the limiting frame 6. The limiting frame 6 has multiple clamping plates 8 evenly spaced along its circumference for clamping and fixing aerospace parts. The multiple clamping plates 8 are slidably connected to the side wall of the limiting frame 6 radially. The limiting frame 6 has multiple adjusting members 9 for driving the clamping plates 8 to move and adjust the sliding distance of the clamping plates 8.

[0020] In this embodiment, the aerospace part is installed inside the limiting frame 6, and clamped and fixed by multiple clamping plates 8 against the outer wall of the aerospace part for processing. During processing, rotating the rotating wheel 4 and causing the rotating frame 3 to rotate adjusts the processing angle of the aerospace part, and rotating the limiting frame 6 flips the aerospace part over to process multiple sides of the aerospace part. The fixing fixture for processing aerospace parts provided in this application, after fixing the aerospace part, allows for flipping the aerospace part and adjusting the processing angle, thus improving the fixing function of the aerospace part.

[0021] Reference Figure 4The first limiting member 5 includes two abutment blocks 51. A bracket 52 is bolted to the mounting base 1 below each of the two rotating wheels 4. The two abutment blocks 51 are vertically slidably mounted on the two brackets 52. A vertical first screw 53 is threaded onto the bracket 52, and one end of the first screw 53 is rotatably connected to the corresponding abutment block 51. A first guide rod 54, parallel to the first screw 53, is also welded to the abutment block 51, and the first guide rod 54 moves through the corresponding bracket 52.

[0022] The second limiting member 7 includes a limiting screw 71. An annular groove 61 for accommodating the rotating frame 3 is provided on the outer wall of the limiting frame 6. The limiting screw 71 is threadedly connected to the side wall of the rotating frame 3 and movably abuts against the inner wall of the annular groove 61.

[0023] The adjusting component 9 includes a second screw 91, which is threadedly connected to the side wall of the limiting frame 6 and is arranged radially along the limiting frame 6. One end of the second screw 91, which passes through the inner side of the limiting frame 6, is rotatably connected to the clamping block. A second guide rod 92, parallel to the second screw 91, is welded onto the clamping block and moves through the side wall of the limiting frame 6.

[0024] In this embodiment, when installing aerospace parts, rotating multiple second screws 91 causes multiple clamping blocks to move and collectively abut against the aerospace parts, thus fixing the aerospace parts. After rotating the rotating wheel 4 and adjusting the processing angle of the aerospace parts, rotating the first screw 53 drives the abutting block 51 to move upward and abut against the rotating wheel 4, thereby restricting the rotation of the rotating wheel 4 and fixing the rotating frame 3. After rotating the limiting frame 6 and flipping the aerospace parts, rotating the limiting screw 71 and abutting against the inner wall of the annular groove 61 fixes the limiting frame 6.

[0025] To improve the fixing effect on the rotating wheel 4, the top of the abutment block 51 is provided with an arc-shaped groove 511 whose size is adapted to the outer wall of the rotating wheel 4. The arc-shaped groove 511 can increase the contact area between the abutment block 51 and the rotating wheel 4.

[0026] Furthermore, a first friction pad 512 for pressing contact with the rotating wheel 4 is provided on the inner wall of the arc groove 511, and a second friction pad 81 for pressing contact with aerospace parts is provided on the clamping block.

[0027] In this embodiment, both the first friction pad 512 and the second friction pad 81 are made of rubber. By pressing the outer wall of the rotating wheel 4 with the first friction pad 512, the frictional force on the rotating wheel 4 is increased, thereby improving the fixing effect on the rotating frame 3. By pressing the outer wall of the aerospace part with the second friction pad 81, the frictional force on the aerospace part is increased, thereby improving the fixing effect on the aerospace part.

[0028] To facilitate the rotation of the rotating wheel 4 by staff, multiple through holes 41 are provided on the rotating wheel 4 for people to pass through.

[0029] Furthermore, a support plate 10 is vertically slidably mounted on the mounting base 1 below the rotating frame 3. A vertical third screw 101 is rotatably connected to the bottom of the support plate 10. The third screw 101 is threaded onto the mounting base 1 to drive the support plate 10 to move vertically. A third guide rod 102 parallel to the third screw 101 is also welded to the bottom of the support plate 10. The third guide rod 102 moves through the mounting base 1.

[0030] During the processing, after the machining position of the aerospace parts is adjusted, rotating the third screw 101 will drive the support plate 10 to move vertically and contact the aerospace parts to support them and further improve the fixing effect of the aerospace parts.

[0031] The implementation principle of a fixing fixture for machining aerospace parts according to an embodiment of this application is as follows: the aerospace part is installed inside the limiting frame 6, and multiple clamping plates 8 abut against the outer wall of the aerospace part to clamp and fix it for machining. During machining, rotating the rotating wheel 4 and driving the rotating frame 3 to rotate can adjust the machining angle of the aerospace part, and rotating the limiting frame 6 can flip the aerospace part to machine multiple sides of the aerospace part. After fixing the aerospace part, it can be flipped and the machining angle can be adjusted, which has the effect of improving the fixing function of the aerospace part.
