制造非标准螺钉,若无专用设备,开槽时装夹困难,为此我们设计制作了开槽简易工装(附图)。经长期使用,效果较好。操作前先根据螺钉槽深度t对好刀,用T形螺栓将此工装固定在铣床工作台上。开槽时先向左拨动摇杆2,退回滑轴6,将待开槽螺钉4插入滑轴夹套7的孔 Non-standard screw manufacturing, without special equipment, slotting difficult folder, we designed and manufactured a simple tooling slotted (with photos). After long-term use, the effect is better. Before operation, according to the depth of the screw groove t, use a T-shaped bolt to fix the tooling on the milling table. Sliding left toggle rocker 2, retract slide 6, the slotted screw 4 will be inserted into the hole in the sleeve 7 of the shaft
