摘要
变壁厚深盲孔零件壁厚的测量,可准确获取壁厚测量值,但无法准确获取壁厚理论值,无法评价壁厚的符合程度。为解决该问题,提出一种基于FARO Edge关节臂的壁厚检测方法,用关节臂完成零件外型面扫描并与三维理论模型对齐后,使用探测模式获取零件内型面点,根据内型面点及三维理论模型获取壁厚理论值,根据外型面数据、内型面点及其壁厚法向计算当前点的壁厚,获得壁厚实测值,二者比较判定壁厚的符合性。同时,制造样件,并与成熟的检测方法的测量值进行比较,验证了方法的正确性,可推广用于各种零件壁厚的检测。
When Variable wall thickness deep blind hole is detected,the measured value of the wall thickness can be accurately obtained,but can’t the accurately theoretical the wall thickness.So the compliance of wall thickness can’t be evaluated.To solve the problem,this paper puts forward a kind of wall thickness detection method based on FARO Edge Arm,after the parts are scanned and aligned with the 3D theoretical model,using detection mode to obtain the inner surface point of the part.The theoretical wall thickness is obtained according to the inner surface point and the 3 d theoretical model;According to the exterior surface data,the inner surface point and its wall thickness direction to calculate the wall thickness.The two were compared to evaluate the conformity of wall thickness.At the same time,the sample is manufactured and compared with the measured value of the mature detection method,which verifies the correctness of the method and can be popularized for the detection of wall thickness of various parts.
