[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a vacuum connection flange drilling device, including an operating table 1, the top of the operating table 1 is fixedly connected to a vacuum box 2, one side of the vacuum box 2 is fixedly connected to an exhaust pipe 6, the top of the vacuum box 2 is movably connected to a cover plate 3, the inside of the cover plate 3 is fixedly installed with a drilling device body 4, and the inside of the vacuum box 2 is fixedly installed with a positioning component 5;

[0025] The positioning assembly 5 includes a positioning tube 51, an extension head 52, a threaded rod 53 and a positioning block 54. The positioning tube 51 is fixedly connected to the box wall of the vacuum box 2, one end of the threaded rod 53 is fixedly connected to one end of the extension head 52, the positioning block 54 is threadedly connected to the outer wall of the threaded rod 53, the threaded rod 53 is located inside the positioning tube 51, and a limiting rod 55 is fixedly installed on the inner wall of the positioning tube 51. The positioning block 54 is slidably connected to the limiting rod 55.

[0026] The following describes in detail the specific configuration and function of this embodiment. A vacuum pump is provided inside the operating table 1. When in use, the cover plate 3 is first opened to place the flange into the vacuum box 2. The vacuum pump then evacuates the interior of the vacuum box 2 to a vacuum environment through the exhaust pipe 6. The drilling device body 4 then drives the drill rod to drill the flange by moving the drilling device body 4 downward. The vacuum pump, vacuum box 2, and drilling device body 4 are prior art and will not be described in detail here.

[0027] The positioning assembly 5 is installed inside the vacuum box 2. Each positioning tube 51 determines the position of a threaded rod 53. When in use, the threaded rod 53 is rotated through the extension head 52. When the threaded rod 53 rotates, it pushes the positioning block 54. The four positioning blocks 54 are evenly spaced at the edge of the vacuum box 2. By moving the positioning blocks 54 in different directions, the position of the flange can be quickly adjusted.

[0028] A limiting rod 55 is set inside the positioning tube 51, and the limiting rod 55 is located on both sides of the positioning block 54. During the movement of the positioning block 54, the limiting rod 55 can not only assist in determining the moving route of the positioning block 54, but also prevent the positioning block 54 from rotating, ensuring that it can be in stable contact with the flange.

[0029] Example 2: Figure 3 and Figure 4 As shown, a closing plate 56 is rotatably connected to the intersection of the extension head 52 and the threaded rod 53, and the closing plate 56 is overlapped at one end of the positioning tube 51. A sealing strip 59 is fixedly installed at the edge of the closing plate 56, and the sealing strip 59 is located at the intersection of the closing plate 56 and the positioning tube 51. A hollow cylinder 58 is fixedly installed on the outer wall of the positioning tube 51, and one end of the hollow cylinder 58 is movably connected to a docking rod 57 through a screw, and one side of the docking rod 57 is overlapped at the edge of the closing plate 56. The sealing strip 59 is located at the intersection of the docking rod 57 and the hollow cylinder 58. The bottom of the vacuum box 2 is fixedly connected to a limiting plate 7, and the limiting plate 7 is fixedly installed inside the operating table 1.

[0030] The effect achieved by the entire embodiment is that the closing plate 56 is located at the pipe mouth of the positioning tube 51, which is used to block the positioning tube 51 and prevent air from entering the interior of the vacuum box 2 from the positioning tube 51. During installation, the closing plate 56 is first covered with the pipe mouth of the positioning tube 51, and then the docking rod 57 and the hollow tube 58 are connected with a screw. The notch on the side of the docking rod 57 can suppress the closing plate 56, and at the same time, the sealing strip 59 at the edge of the closing plate 56 can cover the junction of the closing plate 56 and the hollow tube 58, thereby further improving the airtightness.

[0031] The device is used and works as follows: A vacuum pump is installed inside the operating table 1. Before use, first cover the opening of the positioning tube 51 with the closing plate 56, then insert the screw into the docking rod 57 and connect one end of the screw to the inside of the hollow cylinder 58. Use the notch on the side of the docking rod 57 to press the closing plate 56, and use it in conjunction with the sealing strip 59 to ensure the airtightness of the vacuum box 2.

[0032] Then, the cover plate 3 is opened and the flange is placed in the vacuum box 2. The vacuum pump in the operating table 1 is connected to the vacuum box 2 through the exhaust pipe 6. After the vacuum box 2 is evacuated to a vacuum environment, the drilling device body 4 is used to drive the drill rod and drill the flange by moving the drilling device body 4 downward.

[0033] When the flange needs to be moved during the processing, the threaded rod 53 is rotated by the extension head 52 to drive the positioning block 54. The four positioning blocks 54 are arranged at equal intervals on the edge of the vacuum box 2. The position of the flange can be quickly adjusted by moving the positioning blocks 54 in different directions. During the movement of the positioning block 54, the limit rod 55 can not only assist in determining the moving route of the positioning block 54, but also prevent the positioning block 54 from rotating, thereby ensuring that it can be in stable contact with the flange.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
