Description

Technical Field

[0001] This application relates to the technical field of hole-opening devices, and particularly to an aluminum alloy door and window hole-opening device. Background Art

[0002] Aluminum alloy is one of the most widely used alloy materials in industry. Due to its low density and high strength characteristics, it is widely used in many fields such as aerospace, automobiles, doors and windows, and ships.

[0003] Currently, the production process of aluminum alloy doors and windows is strictly customized according to the specific dimensions of the installation location. After customization, these doors and windows are transported to the installation location and placed in the preset installation position. Immediately afterwards, workers will use an electric drill to drill holes in the aluminum alloy door and window frames and the wall. Subsequently, with the help of fastening components such as bolts, the doors and windows are firmly fixed to the wall to ensure the firmness of the installed doors and windows and meet the usage requirements.

[0004] Although the electric drill plays a key role in the hole-opening operation of aluminum alloy doors and windows and the wall, there are still some problems in actual operation. First of all, the electric drill is mostly held manually during use, and the vibration generated when the drill bit contacts the aluminum alloy door and window and the wall easily causes involuntary shaking of the hand. This not only affects the accuracy of hole opening but also reduces the operation quality. Secondly, during the hole-opening process, continuous pressure needs to be applied to the electric drill to keep the drill bit in close contact with the aluminum alloy door and window and the wall. The pressure application needs to be completed by relying on the hand strength. During the long-term pressure application process, it will cause the operator's hand to feel fatigue and even experience muscle fatigue, thereby reducing the hole-opening efficiency of aluminum alloy doors and windows.

In addition, it can avoid relying on the staff to directly apply pressure to the electric drill, which can not only reduce the fatigue of the staff's hands, but also further improve the efficiency of hole opening for aluminum alloy doors and windows.
