该工具是专为加工三圆弧曲面(图1所示)而设计的,它不但解决了生产难题,而且提高了生产效率。一、结构及工作原理该工具的结构很简单,如图2,主要由蜗杆、蜗轮、轴体以及本体等组成。工作时转动手轮,蜗杆便带动蜗轮旋转。由于蜗轮是装在轴体上的,所以在蜗轮转动的同时轴体也一并旋转。滑块可以在轴体上的方槽内滑动。滚子轴的一端固定在滑块上,另一端装有一滚子。滚子既可在滚子轴上转动,又可在本体的凸轮槽内运动(见图3)。这样当轴体旋转时,由于滑块与滚子的约束作用,滑块既作旋转又在轴体的方
The tool is designed for machining triple arc surfaces (Figure 1) and is designed to solve production challenges and increase productivity. First, the structure and working principle The structure of the tool is very simple, as shown in Figure 2, mainly by the worm, worm gear, shaft body and body composition. Turn handwheel while working, the worm will drive the worm wheel to rotate. Since the worm gear is mounted on the shaft body, the shaft body rotates together with the worm wheel while rotating. The slider can slide in the square groove on the shaft body. One end of the roller shaft is fixed on the slider, and the other end is equipped with a roller. Rollers can rotate both on the roller shaft and in the cam groove of the body (see Figure 3). In this way, when the shaft body rotates, due to the constraint function of the slider and the roller, the slider rotates both on the side of the shaft body
