Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption processing platform technology, specifically a vacuum adsorption processing platform for anti-deformation thin-walled aerospace parts. Background Technology

[0002] The vacuum adsorption processing platform for thin-walled aerospace parts is a specialized workbench designed for processing aircraft parts. Its core principle is to use a vacuum pump to generate negative pressure inside the platform, which in turn generates strong suction through the densely distributed adsorption holes on the platform surface. This suction force adsorbs and fixes the thin-walled aerospace parts covering the platform, providing uniform, stable, and stress-free clamping. This effectively suppresses vibration and deformation during the processing, ensuring high-precision and high-quality processing results.

[0003] However, in existing vacuum adsorption processing platforms, the connection points of the pipes lack reinforcement during use. Vibration or long-term use can lead to loosening of seals and deformation of connections, affecting the stability of the negative pressure during adsorption and potentially causing workpiece displacement or deformation due to pressure fluctuations. Therefore, those skilled in the art have provided a deformation-resistant vacuum adsorption processing platform for thin-walled aerospace parts to address the problems mentioned in the background section. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The anti-deformation mechanism includes a lower reinforcing sleeve, a reinforcing connecting plate fixed to the outer side of the lower reinforcing sleeve, an upper reinforcing sleeve hinged to the top of the lower reinforcing sleeve, anti-slip pads fixed to the inner walls of both the upper and lower reinforcing sleeves, a lower metal pad fixed to the outer side of the lower reinforcing sleeve, a positioning threaded rod fixed to the top of the lower metal pad, an upper metal pad installed on the outer side of the upper reinforcing sleeve, and a positioning threaded sleeve threadedly connected to the outer side of the positioning threaded rod.

[0009] As a further embodiment of this utility model: the outer sides of the metal semi-threaded rod and the metal semi-threaded column are connected by a connecting nut, and the mounting connecting block and the protective cover are fixedly connected.

[0010] As a further improvement of this utility model: the radius of the metal semi-threaded column is equal to that of the metal semi-threaded rod, and the outer side of the connecting nut is provided with anti-slip texture.

[0011] As a further improvement of this utility model: the lower reinforcing sleeve and the main body of the vacuum adsorption processing platform are fixedly connected, and the corresponding surface of the lower reinforcing sleeve is fitted with the upper reinforcing sleeve.

[0012] As a further improvement of this utility model, the upper metal pad has a groove inside, the size of which is equal to the size of the positioning threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[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 1-4 In this embodiment of the present invention, a vacuum adsorption processing platform for anti-deformation thin-walled aerospace parts includes a vacuum adsorption processing platform body 1, a protective cover 2 fixed on the outside of the vacuum adsorption processing platform body 1, a display instrument 3 provided on the outside of the vacuum adsorption processing platform body 1, a connecting pipe 4 installed on the outside of the vacuum adsorption processing platform body 1, and an anti-deformation mechanism 5 provided on the outside of the vacuum adsorption processing platform body 1.

[0023] The anti-deformation mechanism 5 includes a lower reinforcing sleeve 51, a reinforcing connecting plate 52 fixed to the outside of the lower reinforcing sleeve 51, an upper reinforcing sleeve 53 hinged to the top of the lower reinforcing sleeve 51, anti-slip pads 54 fixed to the inner walls of both the upper reinforcing sleeve 53 and the lower reinforcing sleeve 51, a lower metal pad 55 fixed to the outside of the lower reinforcing sleeve 51, a positioning threaded rod 57 fixed to the top of the lower metal pad 55, an upper metal pad 56 installed on the outside of the upper reinforcing sleeve 53, a positioning threaded sleeve 58 threadedly connected to the outside of the positioning threaded rod 57, the lower reinforcing sleeve 51 and the vacuum adsorption processing platform body 1 fixedly connected, the corresponding surface of the lower reinforcing sleeve 51 fitting against the upper reinforcing sleeve 53, and a groove opened inside the upper metal pad 56, the size of which is equal to the size of the positioning threaded rod 57.

[0024] As one embodiment of this utility model, it also includes a reinforcement mechanism 6, which includes a mounting connecting block 61. A metal semi-threaded rod 62 is fixed to the outside of the mounting connecting block 61. A fixed metal column 63 is installed on the outside of the vacuum adsorption processing platform body 1. A limit pad 64 is fixed to the outside of the metal semi-threaded rod 62. A reinforcement metal plate 65 is connected to the outside of the limit pad 64 through a bearing. A metal semi-threaded column 66 is fixed to the outside of the reinforcement metal plate 65. The metal semi-threaded rod 62 and the metal semi-threaded column 66 are threaded together with a connecting nut 67. The mounting connecting block 61 and the protective cover 2 are fixedly connected. The radius of the metal semi-threaded column 66 is equal to that of the metal semi-threaded rod 62. The outside of the connecting nut 67 is provided with anti-slip texture.

[0025] The working principle of this utility model is as follows: This device is equipped with an anti-deformation mechanism 5. After the connecting pipe 4 and the vacuum adsorption processing platform body 1 are connected, a vacuum pump can be used to generate negative pressure inside the vacuum adsorption processing platform body 1. Through the densely distributed adsorption holes on the surface of the vacuum adsorption processing platform body 1, a strong suction force is generated to adsorb and fix the aviation thin-walled parts covering the vacuum adsorption processing platform body 1 onto the platform. At this time, the user can move the upper reinforcing sleeve 53 on the top of the lower reinforcing sleeve 51, so that the upper metal pad 56 on the outside of the upper reinforcing sleeve 53 can be movably sleeved on the outside of the positioning threaded rod 57, and the corresponding surfaces of the upper reinforcing sleeve 53 and the lower reinforcing sleeve 51 are in contact. Then, the positioning threaded sleeve 58 is threadedly connected to the positioning threaded rod 57, which conveniently completes the fixing of the upper reinforcing sleeve 53 and the lower reinforcing sleeve 51, and the anti-slip pad 54 enhances the fit of the connecting pipe 4 interface, thus playing a reinforcing role. This effectively reduces the loosening of seals caused by vibration or long-term use, maintains a stable negative pressure for adsorption, and avoids workpiece displacement or deformation caused by pressure fluctuations during processing, thus achieving the purpose of preventing deformation. With the reinforcement mechanism 6, after the protective cover 2 and the vacuum adsorption processing platform body 1 are fixedly connected, the mounting connecting block 61 on the outside of the protective cover 2 fits into the vacuum adsorption processing platform body 1. Then, the reinforcement metal plate 65 on the outside of the fixed metal column 63 is rotated, so that the metal semi-threaded column 66 and the metal semi-threaded rod 62 on the outside of the reinforcement metal plate 65 fit together. Then, the connecting nut 67 is used to thread the metal semi-threaded rod 62 and the metal semi-threaded column 66, which conveniently completes the fixation between the metal semi-threaded column 66 and the metal semi-threaded rod 62. This can reinforce the connection between the protective cover 2 and the vacuum adsorption processing platform body 1 and ensure the stable assembly of the protective cover 2.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
