    摘要:

    关节类坐标测量机具有便携性好、质量轻、测量范围大等优点,广泛应用于汽车工业、航空航天、模具制造、大型装备装配等领域的质检工作。关节类坐标测量机由6或者7个旋转关节串联而成,靠近基座的关节一般装有力平衡机构,提高了关节类坐标测量机的易操作性;其测角系统由安装在各旋转关节上的高精度角度编码器实现;光学扫描测头应用于关节类坐标测量机上实现了复杂曲面的非接触快速测量;为得到精确的测量模型,研究了多种建模和参数辨识方法并由不同国际组织提出了关节类坐标测量机的性能评价标准。最后介绍了关节类坐标测量机的关键技术和未来发展趋势。

    Abstract:

    Articulated coordinate measuring machines (ACMMs) have the advantages of portability, light weight, large measurement range, etc., and are widely applied in the quality inspection fields of automotive industry, aeronautics and astronautics, mold manufacturing, assembly of largescale equipment and etc. ACMMs consist of 6 or 7 rotation joints in series. Force balance mechanism is installed on the joint near the base, which improves the operation capability of ACMMs greatly. The angle measuring systems are achieved with high precision angle encoders installed on the rotation joints. Optical scanning probe is applied on ACMMs to achieve the noncontact and rapid measurement of complicated surface. In order to obtain the more accurate measurement model, several methods for modelling and parameter identification are studied, and the performance evaluation standards of ACMMs are proposed by different international organizations. This paper introduces the key technologies and future development trends of ACMMs.
