本文向大家介绍一种简单的相贯管端焊接坡口自动切割机(见图1)。该机凸轮8固定在主轴10上,固定滚子9和机架13相连接,电动机12和减速器11装在小车16上。当电动机转动时,由于凸轮8和固定滚子9的相互作用,使小车16沿导轨15运动,从而带动主轴10即转动又水平往复运动,形成坡口曲线轨迹。圆柱凸轮5一方面和主轴10构成径向动配合,另一方 This article will introduce you to a simple tube-end welded bevel automatic cutting machine (see Figure 1). The machine cam 8 is fixed on the spindle 10, the fixed roller 9 is connected to the frame 13, the motor 12 and the reducer 11 mounted on the car 16. When the motor rotates, the car 16 moves along the guide rail 15 due to the interaction of the cam 8 and the fixed roller 9, so as to drive the main shaft 10 to rotate and horizontally reciprocate to form the groove curve trajectory. On the one hand, the cylindrical cam 5 forms a radial kinematic fit with the main shaft 10 and on the other hand
