自动连续螺母铣槽机的工作原理见下图。工作时,电动机经蜗杆蜗轮轴驱动板形凸轮1,凸轮推动主动滑块8。主动滑块8的曲线槽首先使拉杆3向下移动,压板4将工件2压紧。压紧后,拉杆3不再继续下移,在主动滑块8继续前进时,拉杆3迫使被动滑块6同主动滑块一同前进,被压紧在被动滑块上的工件随之前移进行铣削。凸轮到最高点时行程结束。凸轮曲线下降时,滑
The working principle of automatic continuous slot milling machine is shown in the following figure. During operation, the motor drives the plate cam 1 through the worm wheel worm shaft, and the cam pushes the active slider 8. The curved groove of the active slider 8 firstly moves the pull rod 3 downwards and the pressure plate 4 presses the workpiece 2. After being compressed, the pull rod 3 will not continue to move down. When the active slider 8 continues to move forward, the pull rod 3 forces the passive slider 6 to advance together with the active slider, and the workpiece pressed on the passive slider moves forward to be milled . The stroke ends when the cam reaches the highest point. When the cam curve drops, slide
