They are one of the decisive factors for the development of aerospace engineering technology, and aerospace materials science is also a pioneering branch of materials science. Aerospace materials have excellent high and low temperature resistance, aging resistance, and corrosion resistance, and can adapt to the space environment.

[0003] After retrieval, the Chinese patent publication number CN219379840U discloses "a fixing device for processing special-shaped parts, including a base. Four supporting legs are fixedly installed at the bottom of the base. A first mounting plate is arranged on the top of the base. Second mounting plates are arranged on both sides of the top of the first mounting plate. Special-shaped clamping devices are arranged on the relatively close sides of the second mounting plates. In this fixing device for processing special-shaped parts, the second mounting plate is installed through the setting of the first mounting plate, the special-shaped clamping device is installed through the setting of the second mounting plate and the first motor, and at the same time, the rotation of the special-shaped clamping device is realized to rotate the special-shaped part, so as to meet the needs of different processing angles. At the same time, by disassembling and replacing the special-shaped clamping device relative to the output end of the first motor, the clamping and fixing of special-shaped parts of different sizes can be realized, so as to meet different processing needs".

A cleaning block 13 is installed on the placement plate 12. Both ends of the cleaning block 13 are slidably installed in the chutes on the outer wall of the base 1, and a plurality of evenly distributed brushes are installed on the lower surface of the cleaning block 13. By pushing the cleaning block 13 to move on the placement plate 12, the waste residues on the upper surface of the placement plate 12 can be collected into the interior of the base 1, effectively improving the material utilization efficiency. Four evenly distributed protective plates 16 are fixedly connected to the outer wall of the upper end of the base 1. Each protective plate 16 is fixedly connected to each other, and the lower end inner wall of each protective plate 16 is designed with an inclined surface. The inclined surface design at the lower end of the protective plate 16 enables the waste residues generated during the part processing to slowly slide down the inclined surface onto the placement plate 12, facilitating the collection of waste residues. The waste residues generated during the part processing will accumulate on the upper surface of the placement plate 12. The cleaning block 13 can clean the waste residues accumulated on the upper surface of the placement plate 12 into the interior of the base 1 for collection, effectively improving the material utilization efficiency;

An arc-shaped groove is provided on the outer wall of the mounting block 101, and one end of the locking block 106 is installed in the arc-shaped groove. By rotating the locking block 106 to move in the arc-shaped groove, the fixing and disassembling of parts can be completed, ensuring the normal operation of the entire fixing structure 10. A plurality of uniformly distributed arc-shaped grooves are provided on the rotating block 102, and each clamping rod 104 is slidably inserted into the arc-shaped groove.

At this time, the clamping rod 104 in the arc-shaped groove on the rotating block 102 will start to drive the slider 103 to slide in the chute inside the base 1, and ultimately enable a plurality of fixed clamping blocks 105 to fix the part on the fixing structure 10 from all directions. When it is necessary to adjust the height of the part, just shake the handwheel 3. At this time, the rotating rod 2 will drive the threaded rod 7 to start rotating through the first bevel gear 4 and the second bevel gear 8. Also, because the threaded rod 7 is threadedly connected to the connecting block 6, the connecting block 6 will drive the electric telescopic rod 9 and the part on the fixing structure 10 to move up and down between the two mounting brackets 5, so as to be able to adjust the height for different parts. As the part processing progresses, waste residues will continuously accumulate on the upper surface of the placement plate 12. When it accumulates to a certain extent, the waste residues can be cleaned into the inside of the base 1 for collection by moving the cleaning block 13 left and right.
