20/50吨钳式吊的钳体(如图1),其上两个导槽,外侧是半径6.1米的大圆弧。在B110单臂刨床上安装了一套连杆导槽装置。图2是这套装置的示意图。在刨床移动工作台1上,安装一个绕A_2点转动的工作台2;连杆3的一端用螺钉紧固在转动工作台2的外侧,另一端有一个滚子B,可在导槽4内滚动;导槽4相对工作台1倾斜α角度安装在基础上。工作时,工件装卡在转动工作台2上,随着工作台1的移动,在导槽4的作用下,工件 20/50 ton tongs hanging clamp body (Figure 1), the two guide grooves on the outside is a large radius of 6.1 meters arc. A single rod guide was installed on the B110 single-arm planer. Figure 2 is a schematic view of the device. In the planer movement table 1, the installation of a work around the A_2 point table 2; one end of the connecting rod 3 is screwed to the outside of the rotary table 2, the other end has a roller B can be within the guide groove 4 Rolling; guide 4 relative to the table a tilt angle α installed on the basis. Work, the work piece stuck in the rotating table 2, with the table 1 of the move, under the action of the guide 4, the workpiece
