[0021] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The following describes the fixed-point drilling auxiliary device for door and window processing according to the embodiments of the present invention in conjunction with the accompanying drawings.

[0023] As Figures 1-4 shown, the fixed-point drilling auxiliary device for door and window processing according to the embodiments of the present invention, a fixed-point drilling auxiliary device for door and window processing, may include a workbench main body 1, a moving frame 2, a drilling member 4, and a positioning assembly 3.

[0024] Among them, the moving frame 2 is installed on the workbench main body 1, and the drilling member 4 is installed on the moving frame 2. The positioning assembly 3 is fixedly arranged on the workbench main body 1, and the positioning assembly 3 is located below the drilling member 4.

[0025] The positioning assembly 3 includes a plurality of air extraction cylinders 31, a plurality of air inlet holes 32, a plurality of lifting blocks 33, a plurality of pushing springs 34, a plurality of limiting rods 36, a plurality of limiting grooves 37, a plurality of sealing mechanisms 38, and an air extraction mechanism 39.

[0026] It can be understood that in the initial state, the pushing spring 34 is in a contracted state. Then, the pushing spring 34 in the contracted state pushes the limiting rod 36, and the limiting rod 36 drives the lifting block 33 to move upward and stop due to the limitation of the air extraction cylinder 31.

[0027] Among them, the plurality of air extraction cylinders 31 are respectively installed on the workbench main body 1, and the plurality of air inlet holes 32 are opened on the corresponding air extraction cylinders 31. The plurality of lifting blocks 33 are slidably arranged on the corresponding air extraction cylinders 31, and the tops of the plurality of lifting blocks 33 are all conical.

[0028] It can be understood that the plurality of air extraction cylinders 31 are provided to adapt to different doors and windows. Then, when the doors and windows are placed on the workbench main body 1, the air extraction cylinder 31 under the doors and windows of the corresponding shape can adsorb and fix the doors and windows according to the shape of the doors and windows.

[0029] One ends of the plurality of pushing springs 34 are respectively fixedly connected to the corresponding air extraction cylinders 31, and the other ends of the plurality of pushing springs 34 are fixedly arranged on the corresponding limiting rods 36. The plurality of limiting rods 36 are fixedly arranged on the corresponding lifting blocks 33, and the plurality of limiting rods 36 are respectively located inside the corresponding limiting grooves 37. The plurality of sealing mechanisms 38 are fixedly arranged on the corresponding air extraction cylinders 31, and the plurality of sealing mechanisms 38 are located between the corresponding air extraction cylinders 31 and the air extraction mechanism 39.

[0030] Specifically, when drilling holes in special-shaped doors and windows, it is necessary to first position the special-shaped doors and windows. First, place the doors and windows to be drilled above the workbench main body 1. When placing the doors and windows, due to the gravity of the doors and windows themselves, the doors and windows squeeze the lifting block 33 above the workbench main body 1, causing the lifting block 33 to move downward and contract into the inside of the air extraction cylinder 31 after being squeezed. At this time, the doors and windows contact the top of the air extraction cylinder 31, and then the air extraction mechanism 39 extracts air, creating negative pressure inside the air extraction cylinder 31. Furthermore, the doors and windows on the surface of the air extraction cylinder 31 can be adsorbed and fixed by the negative pressure inside the air extraction cylinder 31 at one end in cooperation with the negative pressure inside the air extraction cylinder 31.

[0031] By placing the doors and windows on the workbench main body 1 and using the negative pressure inside the air extraction cylinder 31 on the workbench main body 1 to adsorb the doors and windows, the effect of guiding and positioning the doors and windows is achieved. Moreover, multiple air extraction cylinders 31 are provided on the workbench main body 1, which can position doors and windows of different shapes, increasing its adaptability.

[0032] As a possible situation, in order to improve the sealing performance between the air extraction cylinder 31 and the doors and windows, a sealing ring needs to be provided at the top of the air extraction cylinder 31. The sealing ring can improve the sealing performance between the air extraction cylinder 31 and the doors and windows. Moreover, most of the hole drilling of the doors and windows is on the door frame, and the door frame wraps and fixes the door panel. Therefore, the door frame is the thickest part of the doors and windows. When the door frame is placed on the workbench main body 1, the door frame contacts the air extraction cylinder 31 to support the entire doors and windows. Only when the doors and windows squeeze the lifting block 33 inside the air extraction cylinder 31 will the negative pressure inside the air extraction cylinder 31 adsorb the doors and windows. If the doors and windows cannot squeeze some of the air extraction cylinders 31, the lifting block 33 inside the air extraction cylinder 31 cannot move downward, and thus the doors and windows cannot be adsorbed.

[0033] In an embodiment of the present utility model, as Figure 3 shown, multiple limiting rods 36 are all square, and multiple limiting rods 36 are respectively slidably arranged inside multiple limiting grooves 37.

[0034] In an embodiment of the present utility model, as Figure 3 and Figure 4As shown in the figure, the sealing mechanism 38 includes a lifting groove 381, two guiding rods 382, a communicating groove 383, a plurality of first communicating holes 384, a plurality of second communicating holes 385, a rotating disk 386, a rotating rod 387 and two guiding grooves 388. Among them, the lifting groove 381 is opened inside the lifting block 33, and the communicating groove 383 is opened on the workbench main body 1; the two guiding rods 382 are fixedly arranged on the lifting block 33, and the two guiding rods 382 are located inside the guiding grooves 388; the plurality of first communicating holes 384 are opened on the workbench main body 1, and the plurality of second communicating holes 385 are located below the plurality of first communicating holes 384; the rotating disk 386 is arranged inside the communicating groove 383, and the rotating disk 386 is connected with the rotating rod 387; the two guiding grooves 388 are oppositely opened on the rotating rod 387.

[0035] In an embodiment of the present utility model, as Figure 4 shown, the two guiding grooves 388 are inclinedly opened.

[0036] In an embodiment of the present utility model, as Figure 1 and Figure 3 shown, the air extraction mechanism 39 includes an interconnected groove 391 and an air extractor 392. Among them, the interconnected groove 391 is opened inside the workbench main body 1, and the interconnected groove 391 communicates with the communicating groove 383; the air extractor 392 is fixedly arranged on the workbench main body 1.

[0037] Specifically, in the actual process, in order to prevent the negative pressure inside the air extraction cylinder 31 from adsorbing the lifting block 33 downward, so that the air extraction holes 32 not squeezed by the doors and windows are opened, and the air inlet holes 32 are opened to continuously introduce air into the air extraction cylinder 31, resulting in a decrease in the negative pressure generated by the air extraction mechanism 39. Based on this, by arranging the rotating disk 386 at the bottom of the air extraction cylinder 31, it can only be connected to the interconnected groove 391 and the air extraction cylinder 31 by rotation. In actual use, when the lifting block 33 is squeezed and moves downward, it will drive the guiding rod 382 to move downward. The downward movement of the guiding rod 382 will cause the guiding rod 382 to squeeze the guiding groove 388, causing the rotating rod 387 to rotate left and right under the guiding rod 382 and the guiding groove 388. The rotation of the rotating rod 387 will drive the rotating disk 386 and the second communicating holes 385 to rotate. The rotation of the second communicating holes 385 will cause the second communicating holes 385 to coincide with the first communicating holes 384, thereby making the interconnected groove 391, the communicating groove 383 and the air extraction cylinder 31 communicate with each other. Then, control the air extractor 392 to extract the air inside the interconnected groove 391 to generate negative pressure inside it, and then the inside of the air extraction cylinder 31 can generate negative pressure to adsorb and position the doors and windows at one end of the air extraction cylinder 31.

[0038] It should be noted that in the initial state, that is, when one end of the lifting block 33 is inside the air inlet hole 32 and seals the air inlet hole 32 (in order to improve the sealing effect of the lifting block 33 on the air inlet hole 32, a sealing ring needs to be installed at the connection between the lifting block 33 and the air inlet hole 32, and then cooperate with the driving force of the pushing spring 34 to make the two closely connected to achieve the sealing effect), at this time, the multiple first communication holes 384 and the multiple second communication holes 385 are in an interleaved state, that is, the communication groove 383 is not connected to the air extraction cylinder 31, and when the multiple first communication holes 384 and the multiple second communication holes 385 coincide, the communication groove 383 is connected to the air extraction cylinder 31.

[0039] In summary, for the door and window processing fixed-point drilling auxiliary device according to the embodiment of the present invention, by placing the door and window on the main body of the workbench and using the negative pressure inside the air extraction cylinder on the main body of the workbench to adsorb the door and window, the effect of guiding and positioning the door and window is achieved. Moreover, the main body of the workbench is provided with multiple air extraction cylinders, which can position doors and windows of different shapes, increasing its adaptability.
