内凸轮激振驱动器摆杆的强度设计

Strength Design on Swing Link of Exciting Vibration Driver with Inner Cam

周向振动钻床是振动孔加工的新型设备,针对其关键部件内凸轮周向振动激振器在实际工作中存在的问题分析了其结构组成、工作原理、运动及受力特点,建立了内凸轮激振器主要零件摆杆的力学模型,导出了摆杆的强度公式及主要尺寸的设计计算公式,讨论了钢制摆杆主要尺寸与摆振圆频率等相关参数的关系。应用该强度公式进行了摆杆的实际结构设计计算,验证了公式的正确性与可靠性,为摆杆的结构设计提供了简便可靠的理论依据。也可为具有类似结构及工作条件的零部件设计提供借鉴。

Peripheral vibration drilling machine is a new equipment vibration hole processing. The structure composition, working principle , motion and stress characteristics on exciting vibration driver with inner cam were analyzed to the key parts of the inner cam circumferential vibration exciter in the actual work of the existing problems, and the mechanical model of main parts swing link was established. The strength design formala for swing link was leaded. The relationship between the main dimension swing link and the circular frequency on the shimmy and other related parameters was achieved. The result of design example to swing link shows that the strength design formula is correct and reliable. It can provide reference for design of similar parts with the structure and working conditions.
