快速获取齿轮全部齿面的三维误差信息,是表征复杂齿面质量的关键和前提。本文基于激光三角测量原理,建立了齿轮线激光三维测量模型,研制出齿轮线激光三维测量仪,可用于生产现场快速获取被测齿轮的三维齿面误差信息并进行质量评定。仪器采用立式结构,主要由基座、精密主轴、圆光栅传感器、控制系统、软件系统等部分组成。精密主轴采用密珠轴系实现高精度回转,保证了被测齿轮的高精度定位与回转。在精密主轴周向布置两个高精度线激光传感器,并根据被测齿轮参数调整其位姿状态;圆光栅实时获取精密主轴的回转角度,并触发采集器实时采集并记录被测齿轮左右齿面的几何信息。开发了齿轮线激光三维测量与评价软件,可实现齿轮齿廓偏差、齿距偏差、拓扑偏差等项目的测量与评定,能够满足5级精度齿轮的检测要求。
Rapidly obtaining the three-dimensional error information for all tooth surfaces of gears is the key and prerequisite for characterizing the quality of complex tooth surfaces.In this paper,based on the principle of laser triangulation,a three-dimensional measurement model with line laser is established for the gear,and the developed measuring instrument can be used to quickly obtain the error information of three-dimensional tooth surface and evaluate the quality of gear.The instrument adopts the vertical structure consisting of base,precision spindle,circular grating sensor,control system and software system,etc.The precision spindle adopts the dense bead shaft system to achieve high-precision rotation,which ensures the high-precision positioning and rotation of measured gear.Two high-precision line laser sensors are arranged in the circumferential direction of the precision spindle,and the positional state is adjusted according to the parameters of measured gear.Specifically,the rotation angle of precision spindle is acquired by the circular grating in real time,and the geometrical information of gears’left and right flanks is collected and recorded by the collector in real time.In conclusion the three-dimensional measurement and evaluation software for the gear has been developed,which can realize the measurement and evaluation of gear′s tooth profile deviation,pitch deviation,topological deviation etc.,and meet the detection requirements of grade 5 precision gear.
