Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: A special fixture for automatic filling of aerospace honeycomb materials, comprising: a fixture base 1, serving as the basic structure of the entire fixture; the fixture base 1 is connected to a positioning plate 4, which serves as the positioning reference for the aerospace honeycomb material; the fixture base 1 is fixedly connected to symmetrical guide rods 7, and the fixture base 1 is fixedly connected to symmetrical fixed shafts 6; a T-shaped base 10, through which the symmetrical guide rods 7 pass respectively, and the T-shaped base 10 moves along the guide rods 7 to clamp the middle part of the aerospace honeycomb material; the T-shaped base 10 is provided with symmetrical straight grooves 12; symmetrical T-blocks 13 are nested in the corresponding straight grooves 12, and the symmetrical T-blocks 13 are fixedly connected to elastic clamping plate assemblies for use... The device provides elastic clamping force to hold aerospace honeycomb materials, ensuring the stability and reliability of the clamping. An electric push rod 14 is fixedly connected to the T-base 10, and the push rod of the electric push rod 14 is fixedly connected to the mounting base 20. Symmetrical connecting rods 9 have one end rotatably connected to the mounting base 20. Symmetrical grooved rods 8 have one end rotatably connected to the corresponding fixed shaft 6, and the other end of the symmetrical connecting rods 9 is rotatably connected to the corresponding grooved rod 8. The round rods of the symmetrical T-blocks 13 are respectively set in the grooves of the corresponding grooved rods 8. When the electric push rod 14 extends, the elastic clamping plate assembly simultaneously approaches the aerospace honeycomb material, achieving clamping of the aerospace honeycomb material.

[0019] The electric push rod 14 is model XDZ12-200.

[0020] The elastic clamping plate assembly includes an L-tube 16, which is fixedly connected to the corresponding T-block 13. A spring 17 and a mounting rod for the clamping plate 15 are disposed within the L-tube 16. One end of the spring 17 is fixedly connected to the L-tube 16, and the other end of the spring 17 is fixedly connected to the mounting rod of the clamping plate 15. This provides elastic clamping force, ensuring the stability and reliability of the clamping.

[0021] The clamp seat 1 is connected to the bearing screw 5, and the screw 5 is threadedly connected to the T-seat 10. By using the screw 5, the T-seat 10 can move along the guide rod 7 when it rotates.

[0022] The screw 5 has a self-locking function.

[0023] Guide rods 11 are respectively provided in the symmetrical straight grooves 12. The symmetrical guide rods 11 are fixedly connected to the T-seats 10 and pass through the corresponding T-blocks 13. They are used to guide the movement of the T-blocks 13, ensuring the smooth movement of the T-blocks 13 in the straight grooves 12 and improving the stability and reliability of the fixture.

[0024] The working principle of the special clamp for automatic filling of aviation honeycomb provided by this utility model is as follows: In the initial state, such as Figure 1 As shown, the fixture returns to its initial state after each processing cycle, making it easy to clean the injection material from the surface of the fixture seat.

[0025] The aerospace honeycomb material is placed on the clamp seat 1, with one end contacting the positioning plate 4. The screw 5 is rotated, causing the T-seat 10 to move along the guide rod 7. The T-seat 10 then moves the guide rod 11, T-block 13, L-tube 16, spring 17, clamping plate 15, electric push rod 14, and mounting base 20. The mounting base 20 causes the connecting rod 9 to swing, which in turn causes the groove rod 8 to swing. The groove rod 8 causes the round rod of the T-block 13 to move along its groove, while the T-block 13 moves along the guide rod 11 within the straight groove 12. The T-block 13 then moves the L-tube 16, spring 17, and clamping plate 15, positioning the clamping plate 15 in the center of the aerospace honeycomb material. The electric push rod 14 is then extended, causing the connecting rod 9 to swing, simultaneously moving both clamping plates 15 towards the aerospace honeycomb material, thus clamping the material.

[0026] Example 2: This example further elaborates on Example 1. The mounting base 20 is fixedly connected to symmetrical L-shaped rods 18, which are respectively fixedly connected to U-shaped frames 19. The U-shaped frames 19 are fixedly connected to clamping electric push rods 2, and the push rods of the clamping electric push rods 2 are fixedly connected to auxiliary clamping plates 3. Together with the elastic clamping plate assembly, this achieves the clamping of aerospace honeycomb materials.

[0027] The model of the clamping electric push rod 2 is XDHA12.

[0028] The auxiliary clamping plate 3 is made of rigid sponge. It has a certain degree of softness and elasticity, which can provide cushioning during clamping to prevent damage to the aerospace honeycomb material, while maintaining sufficient clamping force.

[0029] The working principle of the special clamp for automatic filling of aviation honeycomb provided by this utility model is as follows: When the mounting base 20 moves, it drives the L-rod 18, U-frame 19, clamping electric push rod 2 and auxiliary clamping plate 3 to move. After the clamping plate 15 clamps the aviation honeycomb material, it controls the clamping electric push rod 2 to extend, so that the auxiliary clamping plate 3 contacts the aviation honeycomb material, thereby achieving stable clamping of the aviation honeycomb material.
