[0020] In order to make the invention purpose, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present.

[0022] The technical solution of the present invention will be further described below with reference to the drawings and through specific embodiments.

[0023] Embodiment 1: The embodiment of the present invention provides a grinding jig for aviation parts, as Figures 1 to 13 shown, including: an adsorption component 10 and a moving component 20. The moving component 20 is used to drive the adsorption component 10 to move for processing. The adsorption component 10 includes an adsorption substrate 11, a sealing ring 12, a liquid cooling plate 13, and an adsorption top plate 14 that are sequentially stacked along a first direction; Among them, the adsorption substrate 11, the sealing ring 12, and the liquid cooling plate 13 enclose to form a vacuum chamber. At least one air extraction port 141 is installed on the adsorption top plate 14; at least one adsorption hole 1311 is provided on the liquid cooling plate 13. The adsorption hole 1311 and the air extraction port 141 are respectively connected to the vacuum chamber. The adsorption hole 1311 is used to vacuum adsorb the aviation part on the adsorption top plate 14, and the liquid cooling plate 13 is used to cool the adsorption top plate 14. In this embodiment, the adsorption substrate 11, the sealing ring 12, the liquid cooling plate 13, and the adsorption top plate 14 are all fixedly connected by screws. The air extraction port 141 is connected to an external vacuum device, and the vacuum chamber is evacuated by the external vacuum device, so that the aviation part is adsorbed and fixed at the adsorption hole 1311. The vacuum device is a common device in the art and will not be elaborated here.

[0024] It should be noted that for the grinding jig for aviation parts provided by the present invention, through the combined use of the adsorption hole 1311 and the air extraction port 141, the aviation part is strongly vacuum adsorbed. Through the setting of the liquid cooling plate 13, not only a stable adsorption force is provided during the vacuum adsorption process, but also the adsorption top plate 14 can be effectively cooled, preventing the aviation part from deforming due to high temperature and ensuring the processing quality. The separation design of the adsorption component 10 and the moving component 20 of this jig makes the jig have better flexibility and maintainability, can adapt to the processing of different types of aviation parts, and there is no need to replace the entire jig, saving time and cost. Through the integrated adsorption mechanism and cooling function, this jig reduces manual intervention and complex operations, improves the processing efficiency, realizes high-precision, high-efficiency and safety in the processing of aviation parts, and has a wide application prospect.

[0025] As Figures 4 to 9 shown, at least one through hole 142 is provided on the adsorption top plate 14, the liquid cooling plate 13 includes an air vent column 131 inserted into the through hole 142, and the adsorption hole 1311 is formed through the air vent column 131. In this embodiment, both the through hole 142 and the adsorption hole 1311 are circular holes, the air vent column 131 is cylindrical, and both the through hole 142 and the adsorption hole 1311 are arranged in a matrix. The adsorption end face of the adsorption top plate 14 is flush with the end face of the air vent column 131.

[0026] It should be noted that due to the matrix distribution of the through hole 142 and the adsorption hole 1311, this fixture can adapt to various shapes and sizes of aviation parts. The matrix configuration optimizes the distribution of the adsorption force, making the adsorption force more uniform during the processing, thus significantly improving the processing accuracy of various aviation workpieces and also meeting the requirements of batch processing.

[0027] As Figures 4 to 13 shown, the liquid cooling plate 13 further includes a first plate 132 and a second plate 133 connected to each other. Both the first plate 132 and the second plate 133 are internally provided with coolant and form a stepped structure. The first plate 132 is connected between the adsorption top plate 14 and the sealing ring 12, and the second plate 133 is connected to the air vent column 131; Among them, an installation groove 143 communicating with the through hole 142 is provided on the adsorption top plate 14, the second plate 133 is inserted into the installation groove 143, and the second plate 133 is provided with a receiving cavity 1331 communicating with the adsorption hole 1311. The receiving cavity 1331, the adsorption substrate 11, and the sealing ring 12 enclose to form a vacuum chamber. In this embodiment, both the cross-section of the second plate 133 and the installation groove 143 are square.

[0028] It should be noted that since the first plate 132 and the second plate 133 form a stepped structure, the heat exchange area between the coolant and the equipment is effectively increased. This structure greatly improves the heat dissipation efficiency of the liquid cooling plate 13, ensuring that the adsorption top plate 14 remains within a stable temperature range during the processing, and avoiding part deformation and processing accuracy problems caused by excessive temperature. By enclosing the receiving cavity 1331, the adsorption substrate 11, and the sealing ring 12 to form a vacuum chamber, a continuous and stable vacuum state is ensured during the processing, thereby greatly improving the processing quality and efficiency. Due to the square cross-section of the second plate 133 and the installation groove 143, higher assembly efficiency and matching degree are provided, facilitating high-precision positioning. At the same time, the square structure can reduce deformation caused by uneven force, enhance the compressive resistance of this grinding fixture, and adapt to more complex processing environments.

[0029] As Figures 4 to 13As shown, a first flow channel 1323 is provided inside the first plate 132. An inlet 1321 and an outlet 1322 are provided at the same end of the first plate 132. A second flow channel 1332 is provided inside the second plate 133; in this embodiment, the second flow channel 1332 is arranged in a serpentine shape; the first flow channel 1323 and the second flow channel 1332 are arranged in a layered manner in the first direction; Among them, the ventilation column 131 is arranged adjacent to the second flow channel 1332. The inlet 1321 is respectively communicated with the inlet ends of the first flow channel 1323 and the second flow channel 1332, and the outlet 1322 is respectively communicated with the outlet ends of the first flow channel 1323 and the second flow channel 1332; both the first flow channel 1323 and the second flow channel 1332 are used to accommodate the circulation of the coolant. The coolant enters through the inlet 1321, flows to the first flow channel 1323 and the second flow channel 1332 respectively, and converges at the outlet 1322 and flows out, thereby realizing the rapid cooling of the adsorption top plate 14. The coolant can be pumped by a circulation pump, which will not be elaborated here.

[0030] It should be noted that since the second flow channel 1332 is arranged in a serpentine shape, a longer flow path is provided, enabling the coolant to fully exert its cooling effect during the flow process. This design avoids dead corners of the coolant in the flow channel, enabling heat to be effectively taken away and achieving a faster cooling effect, thereby keeping the adsorption top plate 14 within an ideal working temperature range. By connecting the inlet 1321 and the outlet 1322 to the first flow channel 1323 and the second flow channel 1332 respectively, an integrated liquid flow system is formed. When the coolant enters, it can flow to the two flow channels respectively, supporting parallel cooling processing, improving the efficiency of the cooling system, and ensuring the temperature control stability of the adsorption top plate 14.

[0031] As Figures 4 to 13 shown, a first sealing groove 1324 is provided on the first plate 132, and a second sealing groove 111 is provided on the adsorption substrate 11; the sealing ring 12 includes a sealing body 121, and a first sealing portion 122 and a second sealing portion 123 are provided on the sealing body 121; in the specific implementation process, the sealing body 121, the first sealing portion 122 and the second sealing portion 123 are of an integrally formed structure, and the sealing ring 12 can be made of rubber or silica gel; Among them, the first sealing groove 1324, the second sealing groove 111, the first sealing portion 122 and the second sealing portion 123 are all arranged in a loop shape, and the sealing body 121 is respectively in contact with the first plate 132 and the adsorption substrate 11; the first sealing portion 122 is located inside the first flow channel 1323 and is inserted into the first sealing groove 1324, and the second sealing portion 123 is located outside the first flow channel 1323 and is inserted into the second sealing groove 111.

[0032] It should be noted that since the first sealing groove 1324, the second sealing groove 111, the first sealing portion 122 and the second sealing portion 123 are arranged in a loop shape, the sealing contact area is increased, which helps to improve the effectiveness and stability of the vacuum chamber sealing, and then stably vacuum adsorb the aviation parts. The integrally formed structure of the sealing body 121, the first sealing portion 122 and the second sealing portion 123 simplifies the production process, and at the same time reduces the complexity in the assembly process by reducing the number of components. This design not only improves the production efficiency, but also helps to reduce the problem of poor sealing in the assembly, thereby enhancing the reliability of this grinding fixture.

[0033] Specifically, a first groove 1221 is formed on the first sealing portion 122, and a second groove 1231 is formed on the second sealing portion 123. The cross-sections of the first groove 1221 and the second groove 1231 are both arranged in a U shape or a V shape.

[0034] It should also be noted that due to the U-shaped or V-shaped cross-section design of the first groove 1221 and the second groove 1231, the contact area between the sealing portion and the sealing groove can be effectively enlarged. This design can improve the fit degree of the sealing interface, reduce the entry of gas, and thus enhance the airtightness of the vacuum chamber. The structural design of the U-shaped or V-shaped groove provides a certain degree of flexibility, enabling the sealing body 121 to adapt to thermal expansion or cold contraction caused by temperature changes during the processing. This deformation adaptability effectively reduces the risk of sealing failure caused by uneven pressure, ensuring continuous vacuum adsorption force. The design of the U-shaped or V-shaped groove can form a natural pressure distribution under different pressure conditions, thereby reducing the local stress at the sealing part and enabling the sealing ring 12 to balance the pressure difference.

[0035] As Figures 10 to 13 shown, a first boss 134 and a second boss 135 are provided at the same end of the second plate 133. A first connecting flow channel 1341 is arranged inside the first boss 134, and a second connecting flow channel 1351 is arranged inside the second boss 135; Among them, the first boss 134 is adjacent to the liquid inlet 1321, the second boss 135 is adjacent to the liquid outlet 1322. The two ends of the first connecting flow channel 1341 are respectively communicated with the liquid inlet 1321 and the second flow channel 1332, and the two ends of the second connecting flow channel 1351 are respectively communicated with the liquid outlet 1322 and the second flow channel 1332; a first groove 144 corresponding to the first boss 134 and a second groove 145 corresponding to the second boss 135 are arranged inside the adsorption top plate 14. In this embodiment, both the first groove 144 and the second groove 145 communicate with the installation groove 143. The ventilation column 131, the first plate 132, the second plate 133, the first boss 134 and the second boss 135 are all integrally formed structures.

[0036] It should be noted that through the setting of the first connecting flow channel 1341 and the second connecting flow channel 1351, the first flow channel 1323 and the second flow channel 1332 are interconnected, making the flow path of the coolant more convenient and efficient. Through the positioning and cooperation of the first boss 134 and the first groove 144, and the positioning and cooperation of the second boss 135 and the second groove 145, the liquid cooling plate 13 can be positioned and installed, which can further reduce the deformation caused by uneven stress, further enhance the compressive capacity of this grinding jig, and adapt to more complex processing environments.

[0037] It also should be noted that the coolant first enters the first flow channel 1323, and then enters the second flow channel 1332 through the first connecting flow channel 1341; this solution ensures that the liquid cooling medium has more space and time to contact the adsorption top plate 14 during the cooling process. In particular, the flow path of the coolant in the first flow channel 1323 is short and continuous, enabling a relatively direct temperature control effect. The longer path of the serpentine second flow channel 1332 helps to further cool down, ensuring a uniform cooling effect for the entire liquid cooling system. The flow uniformity in the liquid cooling system can help the adsorption hole 1311 area maintain a relatively stable negative pressure, contributing to improving the adsorption effect. The coolant first entering the first flow channel 1323 can effectively cooperate with the contact surface between the first sealing groove 1324 and the second sealing groove 111, ensuring that the sealing ring 12 functions better under uniform stress.

[0038] In summary, since the coolant first enters the first flow channel 1323 and then is divided and enters the second flow channel 1332; this solution can ensure that the flow of the coolant is more uniform and stable, thereby improving the cooling efficiency, ensuring temperature control and negative pressure stability in the adsorption hole area, enhancing the adsorption effect; at the same time, it also contributes to the stability and working efficiency of the sealing ring 12. This flow channel configuration enables the liquid cooling system to better support the cooling and adsorption processes of the entire jig, thereby improving the overall processing accuracy and efficiency.

[0039] Such as Figure 1 and Figure 2As shown in the figure, the moving component 20 includes a first moving module 21 and a second moving module 22 which are connected to each other. The first moving module 21 is used to drive the adsorption component 10 to move linearly along the second direction, and the second moving module 22 is used to drive the first moving module 21 to move linearly along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. In this embodiment, the first moving module 21 includes a first base frame 211. A first sliding table 212 is slidably connected to the first base frame 211. A first sliding plate 213 is fixedly connected to the first sliding table 212. A first moving motor 214 is installed at one end of the first base frame 211. The first moving motor 214 is used to drive the first sliding table 212 to move linearly along the second direction, so that the first sliding plate 213 drives the adsorption component 10 to move. The second moving module 22 includes a second base frame 221. A second sliding table 222 is slidably connected to the second base frame 221. The second sliding table 222 is fixedly connected to the first base frame 211. The second base frame 221 is perpendicular to the first base frame 211. A second moving motor 223 is installed at one end of the second base frame 221. The second moving motor 223 is used to drive the second sliding table 222 to move linearly along the third direction.

[0040] It should be noted that by controlling the movement of the adsorption component 10 in the second direction through the first moving module 21 and controlling the movement of the adsorption component 10 in the third direction through the second moving module 22, the adsorption component 10 can be flexibly operated in a two-dimensional space, meeting the requirements for processing different parts or materials. It can be applied to machining center equipment, which helps to improve the overall processing efficiency and adaptability. The perpendicular arrangement of the first moving module 21 and the second moving module 22 makes the equipment structure compact and optimizes the space utilization of the working area. Through reasonable design, the overall occupied space of the equipment is reduced, making it more suitable for the environment of long-term stable operation and facilitating operation in a limited factory space.

[0041] As Figures 1 to 3 shown in the figure, a buffer component 30 is installed between the adsorption component 10 and the first moving module 21. The buffer component 30 is used to elastically buffer the processing operation of the adsorption component 10 in the first direction. In this embodiment, the buffer component 30 is respectively connected to the adsorption substrate 11 and the first sliding plate 213, and the number of the buffer components 30 is set to two.

[0042] It should be noted that through the setting of the buffer assembly 30, the impact and vibration generated by the adsorption assembly 10 during operation are effectively absorbed. Through the elastic buffering of the adsorption assembly 10, the position deviation or deformation of parts caused by instantaneous impact can be reduced. This precise control helps to improve the stability during the processing operation, thereby improving the processing accuracy and ensuring that the aviation parts can meet the expected quality standards during the processing. The damping effect exerted by the buffer assembly 30 during the processing operation helps to reduce the direct contact wear between parts and components, and reduces the failure rate of this grinding fixture during long-term use.

[0043] As Figure 2 and Figure 3 shown, the buffer assembly 30 includes a buffer plate 31 fixedly connected to the adsorption substrate 11. Buffer columns 32 are provided on the buffer plate 31, and buffer springs 33 are sleeved on the outer walls of the buffer columns 32. In the specific implementation process, the number of buffer columns 32 and buffer springs 33 is both set to three. Among them, the buffer spring 33 abuts against the first moving module 21. A limiting rod 34 connected to the buffer column 32 is embedded in the buffer spring 33, and the limiting rod 34 is movably abutted against the first moving module 21 under the elastic force of the buffer spring 33. In this embodiment, the limiting rod 34 is arranged in an inverted T shape. One end of the limiting rod 34 movably passes through the first slide plate 213 and is threadedly connected to the buffer column 32, and the buffer column 32 and the buffer plate 31 are of an integrally formed structure.

[0044] It should be noted that through the combination of the buffer plate 31 and the buffer column 32 and the addition of the buffer spring 33, an efficient damping system is formed. The buffer spring 33 can absorb and release energy when subjected to external forces, effectively reducing the impact and vibration of the adsorption assembly 10 during operation, ensuring the stable operation of the adsorption assembly 10, and thereby improving the working efficiency and accuracy of this grinding fixture. Under the elastic support of the buffer spring 33, the limiting rod 34 can simply move within a predetermined range, so as to adapt to different working conditions and provide better operating performance.

[0045] Embodiment Two: The embodiment of the present invention provides a processing method, which is applied to the grinding fixture for aviation parts as in Embodiment One, as Figure 14 shown, including: Step S1, moving the adsorption assembly 10 to the loading position through the moving assembly 20. In this embodiment, this grinding fixture can be applied in a machining center. Step S2, loading the aviation part onto the adsorption assembly 10, and the adsorption assembly 10 performs vacuum adsorption on the aviation part. In the specific implementation process, the aviation part can be loaded through a commonly used manipulator in the art or can be loaded manually, which will not be elaborated here. Step S3: Move the adsorption component 10 to the processing position through the moving component 20, and perform grinding treatment on the aviation part on the adsorption component 10. In this embodiment, the aviation part is ground by a commonly used grinding structure in the art, which will not be elaborated here. Step S4: After the grinding of the aviation part is completed, move the adsorption component 10 to the blanking position through the moving component 20. The adsorption component 10 releases the adsorption and fixation of the aviation part, and the aviation part on the adsorption component 10 is blanked. In the specific implementation process, the aviation part can be blanked by a commonly used manipulator in the art or manually, which will not be elaborated here. It should be noted that in step S1, moving the adsorption component 10 to the loading position through the moving component 20 and quickly positioning the adsorption component 10 can significantly shorten the loading time. In step S2, the adsorption component 10 performs vacuum adsorption on the aviation part to ensure that the workpiece remains stable throughout the processing process and prevent the processing quality from being affected by improper position. In step S3, the moving component 20 accurately moves the adsorption component 10 to the processing position, thus ensuring the positioning and stability of the aviation part. This step can achieve complex processing tasks, reduce the vibration of the workpiece during the processing process, and ensure the processing accuracy. In step S4, after the processing, the adsorption component 10 is moved to the blanking position through the moving component 20, and the adsorption and fixation are quickly and safely released for blanking. This fast blanking method avoids the time waste caused by the slow processing process and improves the production efficiency.

[0046] In summary, the implementation of this processing method makes full use of the integrated design of the fixture, enabling seamless connection of steps such as loading, processing, etc., and improving the overall efficiency of the production line. This integrated structure reduces the equipment configuration and human resource costs, making the processing of aviation parts more economical. This processing method can be applied to the processing requirements of different types of aviation parts, so it has good adaptability and flexibility. Users can configure different adsorption components according to specific operation needs and quickly adjust the method to meet the operation requirements of different workpieces.
