Generally, the square head taper screw plug (HT250) is produced in small and medium batches. The machining process is to use a certain length of cast iron bar, first turn the taper thread, cut it, and finally use the special clamp ring to clamp the thread part milling on the horizontal milling. . The disadvantage of the special clip-clamp cone milling is that the workpiece is easy to jump out and the tool is broken, causing the clamp ring and the workpiece to be scrapped frequently. To this end, we designed the fixture as shown in the figure to overcome the above shortcomings and to clamp 4 pieces at a time, which greatly improved the work efficiency.
