[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] The following gives specific embodiments.

[0023] See Figures 1 to 3 , a fixture for machining aviation parts that is convenient for adjustment, including a workbench 1, a lifting table 2, a first limit clamp seat 3, and a second limit clamp seat 14. The lifting table 2 is installed on the workbench 1, the first limit clamp seat 3 is installed on the lifting table 2, an installation frame 4 is installed on the bottom side of the workbench 1, a pneumatic cylinder 5 is installed on the bottom side of the installation frame 4, and the telescopic end of the pneumatic cylinder 5 is connected to the lifting table 2. Guide rods are installed around the bottom side of the lifting table 2, and the guide rods penetrate through the installation frame 4. When the pneumatic cylinder 5 works, it drives the lifting table 2 and the first limit clamp seat 3 to lift, which can not only adjust the height of the aviation parts before clamping and fixing, but also separate the first limit clamp seat 3 from the aviation parts after clamping. A ring seat 6 is rotatably installed on the workbench 1 and outside the lifting table 2. The ring seat 6 is connected to the workbench 1 through a bearing. External teeth 7 are provided on the outer side of the ring seat 6. A first motor 8 is installed on the bottom side of the workbench 1. A rotating tooth 9 is installed at the output end of the first motor 8, and the rotating tooth 9 meshes with the external teeth 7. By working the first motor 8 to drive the rotating tooth 9 to rotate and cooperate with the meshing external teeth 7, the rotation of the ring seat 6 and the aviation parts is realized. Adjusting seats 10 are symmetrically installed on the outer side of the ring seat 6, and sliding arms 13 are slidably installed on the adjusting seats 10. A second motor 11 is installed at the end of the adjusting seat 10. A threaded rod 12 is installed at the output end of the second motor 11, and the threaded rod 12 is threadedly connected to the sliding arm 13. By working the second motor 11 to drive the threaded rod 12 to rotate, the sliding arm 13 connected by the thread is driven to move. A second limit clamp seat 14 is rotatably installed on the opposite sides of the two sliding arms 13. A third motor 15 is installed on the outer side of the sliding arm 13, and the output end of the third motor 15 is connected to the seat body 16 of the second limit clamp seat 14. By working the third motor 15, the second limit clamp seat 14 and the aviation parts are driven to rotate;

[0024] Both the first limit clamp seat 3 and the second limit clamp seat 14 include a seat body 16. A plurality of air cavities 17 communicated with an air pump through a control valve are opened in the seat body 16. A piston 19 is installed in the air cavity 17. A piston rod 18 is installed on the piston 19. According to the external contour structure of the aviation parts, the piston rod 18 drives the piston 19 to move in the air cavity 17 to ensure that the top end of the piston rod 18 contacts the aviation parts, and then the control valve is closed. The piston rods 18 are fixed differently, which is convenient for supporting, limiting, and clamping the aviation parts.

[0025] Place the aviation part on the first limiting clamp seat 3. At this time, according to the bottom contour structure of the aviation part, the piston rod 18 drives the piston 19 to move in the air chamber 17 to ensure that the top end of the piston rod 18 contacts the aviation part. Then close the control valve, and the piston rod 18 is fixed. At this time, the aviation part is supported and limited. The second motor 11 works to drive the threaded rod 12 to rotate, thereby driving the sliding arm 13 connected by threads to move until the second limiting clamp seat 14 contacts the side wall of the aviation part. And according to the side wall contour structure of the aviation part, the piston rod 18 expands and contracts in the air chamber 17 to adjust the contact between the end of the piston rod 18 and the aviation part. Then close the control valve. At this time, the aviation part is clamped and fixed by the two second limiting clamp seats 14. The air cylinder 5 contracts to drive the lifting platform 2 and the first limiting clamp seat 3 to move downward. The first motor 8 works to drive the rotating gear 9 to rotate, which cooperates with the meshing external gear 7 to realize the rotation of the ring seat 6 and the aviation part. At the same time, the third motor 15 works to drive the second limiting clamp seat 14 and the aviation part to rotate, thereby realizing multi-angle adjustment of the clamped aviation part.
