摘要：现有立方体保温绝热材料应用广泛，而对其切削处理需分别采用三台机床独立加工，分三道工序对上下、左右和前后六个表面进行，过程繁项、效率低下、人工参与较多且安全得不到保证。针对上述问题，进行综合设计和改进，经过优化设计的全自动切削机床，采用流水线工序全面实现工件的夫持、运送和翻转的全自动控制。重点设计了翻转装置和夹持装置，同时用ANSYSWorkbench对关键零部件夹持板和轴进行有限元分析，结表明其强度和应变均满足设计要求。该组合切削机床用于立方体工件六个表面全自动加工，工作范围大、生产效率高、环境污染小、有效确保整个加工过程的安全性。

Abstract: The existing cube thermal insulation material is widely used. The cutting treatment of these mate-rial need independent processing by using three machine tools. Three processing procedures are performed on six cube surfaces involving up and down, left and right, as well as front and rear. The present cutting process is complicated, inefficient, much labor force participation and no security guaranteed. Therefore, aasaaeeoeaasa design of automatic cutting machine applied pipe lining procedure to achieve full-automatic control of work piece clamping, conveying and rolling-over. This design focused on the turnover units and holding devices The finite-element analysis for key components, clamping plates and shafts was studied by using ANSYS Workbench, which proved the strength and strain of them met our design requirements. The combined cut-ting machine can be used in fully automatic machining on six surfaces of the cube work piece. Its large work range , high productivity and little environmental pollution effectively ensured the safety of the whole proces-ses.

0引言
对于像无机保温绝热材料等多孔、较脆的立方体工件六个表面（上下、左右和前后）的切削加工，现有的加工工序一般将工件放在手推小车上，向前推动小车，高速转动的锯片铣刀就会切去工件两侧多余的材料，手动转动工件90°后，切削其余两侧面，加工完四个侧面后，将工件平放，推动小车前进，分别加工上下两个表面。为了确保所需面足够平整，最

后还要用滚刀铣削加工表面，每道工序只能加工一个或者两个表面，各工序间都需要人工手动参与操作，危险系数大、劳动强度高、效率低下，工件精度很难保证，并且防尘效果差、环境污染严重、噪声危害很大[14]
为此，设计采用专业流水线工序，工件的夹持、
运送和翻转均实现了全自动控制，便用工作范围增大，生产效率显著提高，整个加工过程更加安全、可靠[56]。
