Abstract: Abstract High-precision electric tools are widely applied in modern manufacturing and assembly processes, where machining accuracy, operational stability, and service reliability are closely associated with the mechanical performance of the connection mechanism between the drill chuck and the drive shaft. Existing studies indicate that conventional drill chuck connection structures often suffer from stress concentration, limited rigidity, and degradation of positioning accuracy under high-speed and high-torque working conditions. Focusing on high-precision electric tool drill chuck connection mechanisms, this paper presents a comprehensive analysis of their mechanical characteristics and economic performance from theoretical, numerical, and experimental perspectives. Based on representative structural configurations, mechanical modeling, finite element numerical simulations, and experimental data reported in related studies are systematically examined to evaluate stress distribution, contact pressure evolution, torsional stiffness, and axial stability under different loading conditions. The analysis results suggest that optimized connection structures can effectively improve torque transmission performance, structural stability, and service life, while significantly alleviating local stress concentration phenomena. In addition, considerations of material selection, structural compactness, and manufacturability are discussed from an economic perspective, highlighting potential cost savings in production and maintenance without compromising mechanical performance. Furthermore, good consistency among theoretical analysis, numerical simulation, and experimental observations is observed, indicating the reliability of commonly adopted analysis approaches. This study provides a structured overview of the mechanical and economic performance characteristics of drill chuck connection mechanisms and offers valuable references for structural design optimization and engineering applications of high-precision electric tools.
