[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and leafs. When aluminum alloy is processed into doors and windows, it is necessary to punch holes in the aluminum alloy to facilitate subsequent assembly through bolts. At present, pistol drills are commonly used in the market for drilling holes in doors and windows.

[0003] During the operation of a traditional pistol drill, it is often difficult to ensure that the drill bit always remains vertical due to the instability of the worker's operation. Once the drill bit is tilted or shaken, the drilled hole will be skewed, affecting the quality and accuracy of the hole, which not only affects the overall aesthetics of the doors and windows, but may also cause inconvenience and safety hazards during installation. Therefore, a hole-opening device for door and window processing is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of instability in workers' operation in the prior art. It is often difficult to ensure that the drill bit always remains in a vertical state.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A hole-making device for processing doors and windows includes a pistol drill 1, on which an external thread 101 is formed, and the pistol drill 1 is threadedly connected to an auxiliary positioning component 2 through the external thread 101, such as Figure 1 , Figure 2 and Figure 5 As shown, an inner wall of the circular hole 2010 at one end away from the supporting cylinder 202 is provided with an internal thread 2012, and the internal thread 2012 is threadedly matched with the external thread 101. Furthermore, the auxiliary positioning assembly 2 is entirely detachable through the threaded match between the internal thread 2012 and the external thread 101, so that workers can easily replace the drill bit.

[0025] The auxiliary positioning assembly 2 includes a column 201 threadedly connected to the pistol drill 1, the column 201 has a through circular hole 2010, a movable groove 2011 is provided on the column 201, a support cylinder 202 is slidably fitted in the movable groove 2011, four springs 203 are arranged in a circular ring shape in the movable groove 2011, the ends of the four springs 203 are fixedly connected to the support cylinder 202, and four support blocks 204 are evenly arranged on the surface of one end of the support cylinder 202 away from the column 201, such as Figure 2 As shown, both ends of the support cylinder 202 have circular openings, and the two openings are interconnected, thereby ensuring that the drill bit can smoothly pass through the column 201 and the support cylinder 202 to perform drilling operations.

[0026] like Figure 2 As shown, the support cylinder 202 is made of a transparent plastic material. Furthermore, the support cylinder 202 made of the transparent material makes it easy for the staff to observe the positions of the drill bit and the hole opening point, thereby ensuring the accuracy of the hole opening.

[0027] When in use, the worker first installs the column 201 and the pistol drill 1 with threads. When drilling vertically, the worker observes the position of the drill bit and the hole opening point through the transparent support cylinder 202 and aligns them. Then, the pistol drill 1 is pressed vertically downward, and the support cylinder 202 contacts the workpiece. At the same time, the pistol drill 1 connected to the power supply is started. As pressure is applied downward, the support cylinder 202 squeezes the spring 203, so that the support cylinder 202 can move and shrink into the movable groove 2011. At this time, the support cylinder 202 is still in horizontal contact with the workpiece, and the pistol drill 1 continues to work to complete the drilling. When a worker operates the pistol drill 1 to drill a hole in the aluminum alloy tube, it can ensure that the drill bit always remains vertical during vertical drilling, and the contact between the support cylinder 202 and the surface of the aluminum alloy tube provides a stable support and positioning point for the worker, effectively reducing the shaking and tilting during operation, thereby avoiding the skewness of the drilling hole, which not only improves the accuracy and quality of the drilling, but also reduces the rework and waste caused by the skewness of the drilling hole, thereby improving the overall processing efficiency, and at the same time, it also effectively blocks the debris and dust generated during the drilling process, reducing splashing and pollution.

[0028] The support block 204 includes a short block 2040 fixedly connected to the support cylinder 202. The top of the short block 2040 has a threaded hole 2041. The threaded hole 2041 is internally threadedly connected to an extension block 2042. Figure 1 , Figure 2 and Figure 4 As shown, the short block 2040 and the extension block 2042 are both provided with silicone pads on the side away from the pistol drill 1, and the end of the support cylinder 202 away from the pistol drill 1 is also provided with a silicone pad. Furthermore, the provision of the silicone pad is beneficial to reducing the wear on the surface of the aluminum alloy doors and windows.

[0029] like Figure 4 As shown, the bottom of the extension block 2042 is fixedly connected with a threaded rod 2043, and the threaded rod 2043 is threadedly matched with the threaded hole 2041. Furthermore, when in use, the extension block 2042 can be rotated counterclockwise to make the threaded rod 2043 extend out of the threaded hole 2041, thereby adjusting the distance between the extension block 2042 and the short block 2040, so that the overall length of the support block 204 can be fine-tuned to adapt to the processing requirements of doors and windows of different sizes and shapes, ensure the quality of support positioning, and improve the flexibility and versatility of the device.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
