摘要
依据齿轮啮合原理和环面蜗杆传动特性构建数学模型,搭建空间坐标系。采用模型化坐标测量原理,整个检测系统由高精度直线光栅作为反馈元件与步进电机构成全闭环定位控制系统。下位机采用ARM STM32F407作为主控制器完成硬件电路的设计,上位机采用可视化图形界面虚拟仪器LABVIEW软件。依据建立的误差检测模型和空间坐标系,获得了被测蜗杆、时栅转台和电感测微头的位置信息,经过误差修正得到了被测环面蜗杆的齿面图,螺旋线误差为8.7″。该系统减少了设计和调试的工作量,减低了生产成本。
According to the principle of gear meshing and torus worm drive characteristics to build mathematical model,building space coordinate system. Using modeling coordinates measuring principle,The whole test system by high precision linear grating as the feedback element and stepper motor constitute a full closed-loop position control system,Lower computer use ARM STM32F407 as the main controller to complete the design of the hardware circuit,upper computer use visual graphic interface LABVIEW virtual instrument software. Based on the established error detection model and spatial coordinate system,obtained the worm to be tested,the gate location information of the turntable and inductive micrometer head,through error correction processing has been measured torus worm gear tooth surface,the helix error is 8. 7″. The system reduces the controller design and debugging tasks abundantly,and reduces the production cost.
