[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3, an embodiment of the utility model is provided: an aerospace material processing fixture, comprising a support seat 1, a fixed box 2 is fixedly connected inside the support seat 1, and both sides of the fixed box 2 are fixedly connected to fixed frames 3, and the two fixed frames 3 are fixedly connected to the sides away from each other with cylinders 4, and the output ends of the two cylinders 4 are fixedly connected to clamps 5, and both sides of the clamps 5 are fixedly connected to limit components, and the limit components are used to limit the clamps 5, and the limit components include sliders 6, two sliders 6 are fixedly connected to both sides of the clamps 5, and multiple sliders 6 are slidably connected to the outside of the slide rod 7, and the two slide rods 7 are fixedly connected to both sides of the inside of the fixed box 2, and both sides of the clamps 5 are fixedly connected to limit columns 8, and the other end of the limit columns 8 is fixedly connected to a positioning block 9, and the outer sleeve of the limit columns 8 is provided with a buffer spring 10, and the multiple limit columns 8 are slidably connected to the inside of the fixed box 2, and one end of the buffer spring 10 is fixedly connected to the fixed box 2, and the other end of the buffer spring 10 is fixedly connected to the positioning block 9.

[0025] When the material to be processed is placed on the upper part of the processing table 11, the operator will start the two cylinders 4. The two cylinders 4 serve as the power source of the clamping system, and their output ends accurately control the movement of the splint 5. As the cylinders 4 push, the splint 5 begins to move. During this process, the limit column 8 on the splint 5 slides inside the fixed box 2, which plays a role in positioning and guiding, ensuring the stability and accuracy of the splint 5 during the movement. At the same time, when the limit column 8 moves, it will contact the positioning block 9 and squeeze the buffer spring 10. The buffer spring 10 uses its own elastic effect to provide a stable clamping force for the splint 5. When the two splints 5 are close to each other, the clamping force between them will gradually increase until the material is tightly clamped. This process not only ensures the firmness of the clamping, but also avoids damage to the material due to excessive clamping force. During the movement of the splint 5, they also drive the slider 6 to slide on the outside of the slide rod 7. The slide rod 7 serves as a support and guiding structure for the splint 5, ensuring the stability and linearity of the splint 5 during the movement.

[0026] Reference Figure 2 and Figure 3 The outside of the fixed box 2 is fixedly connected to a support frame 12, the right part of the support frame 12 is fixedly connected to a motor 13, the output end of the motor 13 is fixedly connected to a bidirectional screw rod 14, both sides of the outside of the bidirectional screw rod 14 are threadedly connected to threaded sleeves 15, the bottoms of the two threaded sleeves 15 are rotatably connected to movable support rods 19, the other ends of the movable support rods 19 are rotatably connected to the upper part of the pressing plate 20, both sides of the threaded sleeves 15 are fixedly connected to connecting rods 16, the other end of the connecting rod 16 is fixedly connected to a pulley 17, the pulley 17 is slidably connected to the inside of the slide rail 18, the upper part of the support frame 12 is fixedly connected to a mounting seat 21, and slide rails 18 are provided on both sides of the inside of the mounting seat 21.

[0027] With the continuous output of the motor 13, the bidirectional screw 14 starts to rotate at a stable speed. At the same time, the rotation of the bidirectional screw 14 drives the movement of the threaded sleeve 15 that fits closely with it. When the threaded sleeve 15 moves, it pushes the connecting rod 16 and the pulley 17 to move together. Inside the slide rail 18, the pulley 17 slides in its unique way, which not only reduces friction but also ensures the accuracy of movement. This design greatly improves the efficiency and stability of the system. With the movement of the pulley 17, it transmits the force to the movable support rod 19 through a series of mechanical transmissions. The movable support rod 19 drives the pressure plate 20 to move downward. Under the uniform pressure of the pressure plate 20, the workpiece is firmly fixed on the workbench.

[0028] Reference Figure 3-Figure 5 A placing plate 23 is fixedly connected to the inside of the fixed box 2, a motor 24 is fixedly connected to the upper part of the placing plate 23, a gear 25 is fixedly connected to the output end of the motor 24, a rack plate 26 is meshedly connected to one side of the gear 25, a connecting block 27 is fixedly connected to the right part of the rack plate 26, a movable block 28 is fixedly connected to the upper part of the connecting block 27, a processing table 11 is fixedly connected to the upper part of the movable block 28, the processing table 11 is slidably connected to the upper part of the fixed box 22, a fixed box 22 is fixedly connected to the inside of the fixed box 2, a limiting rod 29 is fixedly connected to one side of the inside of the fixed box 22, a guide rod 31 is fixedly connected to the other side of the inside of the fixed box 22, a guide block 30 is fixedly connected to one side of the bottom of the processing table 11, the guide block 30 is slidably connected to the outside of the guide rod 31, and the movable block 28 is slidably connected to the outside of the limiting rod 29.

[0029] When the operator starts the motor 24, its output end drives the gear 25 to rotate. As the gear 25 rotates, the rack plate 26 starts to move. The movement of the rack plate 26 drives the precise movement of the connecting block 27, and the connecting block 27 further drives the movable block 28 to slide outside the limit rod 29. The sliding of the movable block 28 accurately controls the movement of the processing table 11. When the processing table 11 moves, the guide block 30 will slide outside the guide rod 31. This design ensures that the processing table 11 can move forward smoothly and accurately and move out of the fixed box 2. When the processing table 11 is completely moved out, the operator can easily place the material on the upper part of the processing table 11.

[0030] Working principle: First, the operator starts the motor 24, and the output end of the motor 24 drives the gear 25 to rotate. The rotation of the gear 25 drives the rack plate 26 to move. The movement of the rack plate 26 drives the connecting block 27 to move. The movement of the connecting block 27 drives the movable block 28 to slide outside the limit rod 29. The movable block 28 slides and drives the processing table 11 to move. When the processing table 11 moves, it drives the guide block 30 to slide outside the guide rod 31. Under the action of the guide block 30, the processing table 11 moves forward and moves out from the inside of the fixed box 2. Then, the operator can place the material on the upper part of the processing table 11, thereby conveniently moving the processing table 11 out for loading, which can avoid direct contact with high-speed rotating parts or sharp tools, reduce the risk of work-related accidents, greatly reduce the time for loading and unloading, and improve production efficiency. When the material is placed on the upper part of the processing table 11, start the two cylinders 4, and the output end of the cylinder 4 pushes the splint 5 to move. When the splint 5 moves, it drives the limit The positioning column 8 slides inside the fixed box 2, so that the positioning block 9 squeezes the buffer spring 10. Under the elastic action of the buffer spring 10, the two clamps 5 are close to each other. When the two clamps 5 move, they drive the slider 6 to slide on the outside of the slide rod 7, so that the two clamps 5 slide on the upper part of the processing table 11 to clamp the material. Then, start the motor 13, and the output end of the motor 13 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the threaded sleeve 15 to move. When the threaded sleeve 15 moves, it drives the connecting rod 16 and the pulley 17 to move. When the pulley 17 moves, it slides inside the slide rail 18. Under the action of the pulley 17, the threaded sleeve 15 drives the movable support rod 19 to move. The two movable support rods 19 are close to each other and drive the pressure plate 20 to move downward to press the material, thereby achieving effective clamping and fixing of the material, ensuring the accurate position of the workpiece during the processing, avoiding dimensional deviation caused by workpiece movement or vibration, and meeting the high requirements for part accuracy in the aerospace field.
