[0002] Thin-walled aerospace components refer to a special type of part used in the aerospace industry. They typically have thin walls and must meet high strength and rigidity requirements while also being lightweight. These components are widely used in aircraft structures, such as wings, fuselage skin, and engine nacelles, and are crucial for improving the overall performance of the aircraft.

[0003] Currently, during the processing of thin-walled aerospace parts, although fixtures are used for fixing, there are still problems such as unstable clamping and the bottom of the thin-walled aerospace parts being suspended. Especially due to the dimensional characteristics of thin-walled aerospace parts, they are extremely prone to deformation during processing, so improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant processing device for thin-walled aerospace parts, so as to solve the problem of easy deformation during the clamping and processing of thin-walled aerospace parts mentioned in the background art.

[0011] Preferably, a processing head is provided on the top side of the main frame, and the processing head is located on the top of the upper pressure mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can ensure the stability of clamping during the processing of thin-walled aerospace parts, thereby avoiding the problem of processing deformation caused by vibration of thin-walled aerospace parts.

[0014] (2) This device uses a vacuum adsorption method to fix the bottom of the thin-walled aerospace parts by setting a support mold.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a deformation-resistant processing device for thin-walled aerospace parts, including a worktable 7. A main frame 2 and a support base 10 are fixedly connected to the top of the worktable 7. A processing head 1 is arranged on the top side of the main frame 2, located on the top of an upper pressure mold 8. The processing head 1 is driven by X, Y, and Z axis drives and an angle adjustment motor. The drive equipment can be a linear motor, cylinder, servo motor, etc., to ensure automatic processing of thin-walled aerospace parts by the processing head 1. This part is prior art and will not be described in detail here. A negative pressure pump 11 is fixedly connected to one side of the support base 10, and a connecting pipe 14 is connected to one side of the negative pressure pump 11. The housing of the negative pressure pump 11 is fixed to the support base 10 with screws. The connecting pipe 14 is equipped with... The system includes a solenoid valve 15 and a suction nozzle 13 connected to one end of a connecting pipe 14. A screen 12 is fixedly connected to the inner wall of the suction nozzle 13. This structure uses the screen 12 to intercept dust and impurities, preventing them from entering the suction nozzle 13. The solenoid valve 15 and the negative pressure pump 11 are controlled by a PLC to ensure the automatic opening and closing of the suction nozzle 13. Multiple sets of suction nozzles 13 are provided, with each set containing multiple nozzles. Each set of suction nozzles 13 is symmetrically distributed about the bisector of the support mold 9. The suction nozzles 13 can be fixed to the support mold 9 using screws. The suction force generated at the end of the suction nozzle 13 can adhere and adhere the aerospace thin-walled component to the support mold 9, thereby improving the stability of the aerospace thin-walled component, preventing vibration, and thus preventing damage to the aerospace thin-walled component. In case of deformation due to vibration, a support mold 9 is fixedly connected to the support base 10. Suction nozzles 13 are inserted on both sides of the support mold 9, and one end of each suction nozzle 13 is connected to a negative pressure pump 11. A fixing frame 3 is fixedly connected to the inner wall of the main frame 2, and a cylinder 4 is fixedly connected to the top of the fixing frame 3. One end of the cylinder 4 is fixedly connected to the mounting frame 5. This cylinder 4 can automatically raise and lower the mounting frame 5 and the reciprocating ball screw mechanism 6, thus facilitating the upper pressure mold 8 at the bottom of the reciprocating ball screw mechanism 6 to fit against the top of the aerospace thin-walled part. The reciprocating ball screw mechanism 6 can drive the upper pressure mold 8 to move longitudinally. The upper pressure mold 8 can be adjusted according to the processing position of the processing cutter head 1 to ensure that the processing is not affected while maintaining the integrity of the aerospace thin-walled part. To ensure stable processing of the thin-walled aerospace component, the cylinder 4, mounting bracket 5, reciprocating ball screw mechanism 6, and upper pressure die 8 are symmetrically distributed about the bisector of the fixed frame 3. The upper pressure die 8 is the same size as the support die 9 when assembled. This structure, with the upper pressure die 8 and support die 9 respectively attached to the top and bottom of the aerospace thin-walled component, provides clamping and fixing during processing, thus ensuring the stability of the component and supporting its bottom. The cylinder 4 and reciprocating ball screw mechanism 6 are controlled by a PLC to ensure synchronized movement when multiple cylinders 4 and reciprocating ball screw mechanisms 6 move. The bottom of the fixed frame 3 is connected to the mounting bracket 5, which houses the reciprocating ball screw mechanism 6.A reciprocating ball screw mechanism 6 has an upper pressure mold 8 fixedly connected to its bottom. An aerospace thin-walled component is placed between the upper pressure mold 8 and a support mold 9. The upper pressure mold 8 and the support mold 9 are respectively fitted to the top and bottom shapes of the aerospace thin-walled component. When the two upper pressure molds 8 on the fixing frame 3 are spliced ​​together, they are the same size as the support mold 9, allowing for a close clamping fit to the top of the aerospace thin-walled component. The position of the upper pressure mold 8 can be adjusted as the aerospace thin-walled component is processed. In practical applications, the shapes of the upper pressure mold 8 and the support mold 9 can be customized according to the shape of the aerospace thin-walled component to be processed.

[0023] Working principle: When using this aerospace thin-walled part anti-deformation processing device, first place the aerospace thin-walled part to be processed on the top of the support mold 9. Then, the negative pressure pump 11 is started, and the suction nozzle 13 generates negative pressure to adsorb the aerospace thin-walled part on the top of the support mold 9. Next, the reciprocating ball screw mechanism 6 drives the upper pressure mold 8 to move to the top of the aerospace thin-walled part. Then, the cylinder 4 pushes the upper pressure mold 8 to fit into the appropriate position on the top of the aerospace thin-walled part. At this time, the processing position of the aerospace thin-walled part needs to be exposed. After the aerospace thin-walled part is fixed, the processing cutter 1 begins to process the aerospace thin-walled part.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
