Technical Field
[0001] This utility model relates to the technical field of frame drilling devices, and in particular to a frame drilling device for electric vehicles that prevents waste debris from flying. Background Technology
[0002] Against the backdrop of the rapid development of the electric vehicle manufacturing industry, the frame, as a core load-bearing component, is directly related to the overall vehicle performance and manufacturing efficiency in terms of its processing precision and production safety. In the traditional frame drilling process, the sharp waste chips generated by metal cutting are prone to radiating outwards under the action of high-speed rotating cutters. This not only poses a safety hazard to operators, significantly increasing the risk of injury to exposed parts such as the face and eyes, but also pollutes the production line environment, increasing equipment maintenance costs and downtime for cleaning.
[0003] In the use of chassis drilling devices, traditional drilling devices typically employ an open or semi-closed structure design, with the drill bit directly exposed to the working environment. These devices rely on manual positioning or simple clamps to fix the chassis, depending on the operator's experience to control the drilling position accuracy. In existing technologies, waste chip removal mainly relies on manual sweeping or fixed chip collection troughs, and protective measures are limited to partial drill bit shielding. However, in actual processing, due to the centrifugal force generated by the high-speed rotation of the drill bit and the sharpness of the metal chips, the chips easily splash along irregular trajectories outside the working area. The open structure cannot effectively intercept small particles of waste chips, causing air pollution in the workshop and health risks to operators. Waste chips accumulate in equipment gaps or hidden corners, requiring machine shutdown and disassembly for cleaning, significantly reducing production efficiency. Manual positioning errors and insufficient clamp rigidity cause chassis hole position displacement, affecting assembly accuracy.
[0004] Therefore, to address the aforementioned issues of ensuring processing accuracy while improving waste removal efficiency and preventing environmental pollution, a drilling device for electric vehicle frames that prevents waste splashing can be designed. During the use of the drilling device, when installing the protective shell, multiple sets of connecting rods along the perimeter of the protective shell are vertically inserted into the corresponding connecting holes of the drilling base using the handle. During drilling, the front end of the electric vehicle frame is inserted into the limiting frame through the left entrance of the protective shell. Precise positioning is achieved by utilizing the fit between the limiting frame and the frame contour. The drill bit is then pressed vertically downwards through the positioning hole on the top of the protective shell to perform the drilling operation. At this time, the protective shell forms a closed working area. In this working space, the metal shavings generated during drilling are completely intercepted by the protective shell, falling only to the surface of the drilling base by gravity. After the operation is completed, the protective shell can be quickly disassembled using the handle for shaving removal. The detachable design of the limiting seat and the drilling base facilitates deep cleaning. In summary, this device effectively prevents drilling shavings from splashing through the fully enclosed protective shell, improving the safety of the working environment. Meanwhile, the quick-release locking mechanism significantly improves cleaning efficiency. Compared to traditional drilling devices, this solution effectively improves shaving removal efficiency and reduces environmental pollution while ensuring processing accuracy, demonstrating significant technological advancement and practical value.
