[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Referring to Figures 1-4, a machining clamping device for aerospace assembly parts includes a fixed plate 1 and a carrier plate 2. The carrier plate 2 is fixedly connected to the top of the fixed plate 1. The fixed plate 1 provides fixing points for the carrier plate 2, connecting frame 3, electric telescopic rod 9, support rod 11, and fixing flange 21, which are fixedly connected to its outer surface. The carrier plate 2 is fixedly connected to the top of the fixed plate 1. Before using the device, the part to be processed is moved to the top of the carrier plate 2. The top of the fixed plate 1 is fixedly connected to the connecting frame 3. Two connecting frames 3 are provided, and the connecting frames 3 are located on the outside of the carrier plate 2. The connecting frame 3 is fixedly connected to the top of the fixed plate 1, providing fixing points for the motor 4 and the limiting rod 7, which are fixedly connected to its outer and inner surfaces. The motor 4 is fixedly connected to the outer surface of the connecting frame 3. When... When the workpiece needs to be clamped laterally, electrical energy can be transmitted to the motor 4 via an external control component. The motor 4 then transmits rotational power to the threaded rod 5 via electromagnetic effect. The output end of the motor 4 is fixedly connected to the threaded rod 5. When the rotational power is transmitted to the threaded rod 5 via the motor 4, the threaded rod 5 rotates, transmitting the rotational power to the transmission block 6. The outer surface of the threaded rod 5 is threadedly connected to the transmission block 6. When the rotational power is transmitted to the transmission block 6 via the threaded rod 5, the transmission block 6 converts the rotational power into a linear force, causing the first clamp 8 fixedly connected to its top to move inward. Two limit rods 7 are fixedly connected to the inner side of the connecting frame 3, and these limit rods 7 are fitted into the transmission block 6. The limiting rod 7 is fitted into the transmission block 6 to prevent the transmission block 6 from rotating with the threaded rod 5. A first clamp 8 is fixedly connected to the top of the transmission block 6. The first clamp 8 moves under the drive of the transmission block 6, generating a lateral clamping force on the workpiece to be processed, thus completing the lateral fixation of the workpiece. An electric telescopic rod 9 is fixedly connected to the top of the fixing plate 1. There are two electric telescopic rods 9, and the electric telescopic rods 9 are located outside the connecting frame 3. When it is necessary to clamp the workpiece longitudinally, electrical energy can be transmitted to the interior of the electric telescopic rod 9 through an external control component. At this time, the electric telescopic rod 9 extends, driving the second clamp 10 fixedly connected to its tail end to move. The tail end of the electric telescopic rod 9 is fixedly connected to the second clamp 10. The second clamp 10 moves during the electric telescopic movement. Driven by rod 9, the rod moves inward to generate a longitudinal clamping force on the workpiece, thus fixing the workpiece longitudinally. Four support rods 11 are fixedly connected to the top of the fixing plate 1, and these support rods 11 are located outside the electric telescopic rod 9. The support rods 11 are fixedly connected to the top of the fixing plate 1, providing fixing points for the bearing plate 12 fixedly connected to its inner side. The bearing plate 12 is fixedly connected to the inner side of the four support rods 11, providing fixing points for the storage shell 13 fixedly connected to its top. Four fixing flanges 21 are fixedly connected to the bottom of the fixing plate 1, transmitting the supporting force to its interior via the ground.This provides support for the entire device. When it is necessary to fix the device, external bolts can be inserted into the fixing flange 21 by external force, and then into the external fixing plane to complete the overall fixation of the device.

[0019] Referring to Figures 1 and 3, a storage shell 13 is fixedly connected to the top of the support plate 12. The storage shell 13 is fixedly connected to the top of the support plate 12, providing a connection point for the door 14 connected to its front side via a hinge. It also provides a fixing point for the feed pipe 17 and the conveying pump 20 fixedly connected to its outer surface. The door 14 is fixedly connected to the front of the storage shell 13 via a hinge, providing space for the user to remove metal scraps by external force. Simultaneously, it provides fixing points for the front-mounted latches 15 and latches 16. A set of cabinet doors 14 are fixedly connected to the front with latches 15, which engage with the latches 15 and latches 16 to secure the two cabinet doors 14. Another set of cabinet doors 14 are fixedly connected to the front with latches 16, which insert into the latches 15 to secure the cabinet doors 14. A feed pipe 17 is connected through the bottom of the storage shell 13, extending to the lower part of the support plate 12. When metal scrap enters the feed pipe 17, it is guided by negative pressure to the housing 13. An electric throttle valve 18 is connected to the outer surface of the feed pipe 17. When cleaning of the metal scrap is required, electrical energy can be supplied to the electric throttle valve 18 via an external control component. This opens the electric throttle valve 18, connecting the feed pipe 17 internally. A feed head 19 is fixedly connected to the tail end of the feed pipe 17. The feed head 19 is used... Driven by external force, the metal scrap moves under negative pressure, guiding it into the feed pipe 17. The top of the housing 13 is fixedly connected to a conveying pump 20 via a dustproof net, and there are two conveying pumps 20. When it is necessary to extract the metal scrap, electrical energy can be transmitted to the conveying pump 20 via an external control component. At this time, the conveying pump 20 generates suction on the air inside the housing 13 and delivers the air to the external environment, so that the inside of the housing 13 is in a negative pressure state.

[0020] The functional principle of this utility model can be explained through the following operation: First, insert the external bolt into the inside of the fixing flange 21 and then into the inside of the external fixing plane to complete the overall fixation of the device. Then, move the workpiece to be processed to the top of the bearing plate 2. When it is necessary to clamp the workpiece laterally, electrical energy can be transmitted to the inside of the motor 4 through the external control component. At this time, the motor 4 transmits the rotational power to the inside of the threaded rod 5 through the electromagnetic effect. The threaded rod 5 rotates and transmits the rotational power to the inside of the transmission block 6. The transmission block 6 converts the rotational power into... A linear force drives the first clamp 8, which is fixedly connected to its top, to move inward. The first clamp 8 generates a lateral clamping force on the workpiece to be processed, thus fixing the workpiece laterally. When it is necessary to clamp the workpiece longitudinally, electrical energy can be transmitted to the interior of the electric telescopic rod 9 via an external control component. At this time, the electric telescopic rod 9 extends, causing the second clamp 10, which is fixedly connected to its tail end, to move. Driven by the electric telescopic rod 9, the second clamp 10 moves inward to generate a longitudinal clamping force on the workpiece to be processed, thus fixing the workpiece longitudinally for subsequent processing.
