Description

Technical Field

[0001] This utility model relates to the technical field of drilling devices for automotive parts, and in particular to a drilling device for processing automotive parts. Background Technology

[0002] With the continuous expansion of the global automotive industry and the steady growth of automobile production, the processing quality of parts directly affects the performance and safety of the entire vehicle. Automotive parts are diverse, such as engine blocks, transmission gears, and braking system components. These parts often require drilling. Engine blocks, for example, require numerous high-precision holes for mounting pistons and valves. The precision and surface quality of these holes have a decisive impact on engine power output, fuel economy, and reliability. To meet the automotive industry's demand for high-quality parts, drilling equipment must continuously improve its drilling precision, efficiency, and stability to adapt to increasingly stringent automotive parts processing standards. Simultaneously, with increasing emphasis on safe production, safety standards in the automotive parts processing industry are becoming increasingly stringent. During drilling, the high-speed rotating drill bit, flying chips, and the use of coolant pose numerous safety hazards. To ensure the safety of operators, drilling equipment needs to be equipped with comprehensive protective devices, such as fully enclosed protective doors and covers, and various safety sensors, such as position sensors and pressure sensors, to achieve safety interlock control of the equipment.

[0003] Currently, the drilling equipment available for automotive parts mainly consists of powertrain components and actuator components. Traditional drilling techniques, such as ordinary twist drills, struggle to meet the high precision requirements when machining complex-shaped automotive parts. Because the drill bit is easily affected by cutting forces and friction during the cutting process, it experiences wear and vibration, making it difficult to achieve ideal positional accuracy, hole diameter accuracy, and hole wall roughness. For some high-precision automotive parts, such as high-performance automotive engine components derived from aero-engines, precision deviations in traditional drilling techniques can lead to serious assembly problems, affecting the normal operation of the engine. While the emergence of new sensor drilling equipment has solved the precision problem, it still faces challenges in achieving the desired accuracy. Traditional drilling devices often use Morse taper or threaded connections to fix the drill bit. While Morse taper connections offer good centering accuracy and connection strength, they require specialized tools to knock and disassemble when changing drill bits. This process is cumbersome and can easily damage the taper surface, affecting subsequent installation accuracy. Threaded connections require operators to manually tighten and loosen nuts, which is time-consuming. Furthermore, the threads are prone to wear during frequent disassembly, leading to loose connections and affecting drilling stability. In addition, some special-purpose drilling devices, such as multi-axis linkage drilling equipment for machining complex curved parts, employ more complex installation structures to ensure the stability of the drill bit during multi-directional movement, further increasing the difficulty and time cost of changing drill bits. Utility Model Content
