摘要： A pipe cutting apparatus having a frame and first and second pipe support arms. The pipe support arms are pivotally attached to the frame. First and second pipe support members on the first and second arms together with a third pipe support member securely grip the pipe at substantially equally circumferentially spaced locations. A camming member is used to place the first and second pipe support arms in predefined locations for holding differently sized pipes. An linkage assembly causes the third pipe support member to biasingly engage the pipe. A two-part tool shield is provided together with a depth adjusting assembly for facilitating the cutting and beveling of the pipe. A power transmission assembly transfers power from a motor on the frame to a tool located on a pivoting arm. The frame may be manufactured using an adhesive filler material for enhancing the rigidity, strength and accuracy of the components.
摘要翻译：一种具有框架和第一和第二管支撑臂的管切割装置。管支撑臂枢转地附接到框架。第一和第二管支撑构件与第三管支撑构件一起在第一和第二臂上牢固地以大致相等的周向间隔的位置夹紧管。使用凸轮构件将第一和第二管支撑臂放置在预定位置以保持不同尺寸的管。连杆组件使得第三管支撑构件偏置地接合管。一个两部分的工具屏蔽件与深度调节组件一起提供，以便于管道的切割和斜切。动力传递组件将动力从框架上的马达传递到位于枢转臂上的工具。框架可以使用粘合剂填充材料制造，以增强部件的刚性，强度和精度。
