Description

Thread milling cutter convenient to dismantle and change

Technical Field

The utility model relates to the field of thread milling cutters, in particular to a thread milling cutter convenient to detach and replace.

Background

The traditional thread processing method mainly adopts a thread lathe tool to turn threads or adopts a tap and a die to manually tap and sleeve and buckle, and along with the development of numerical control processing technology, particularly the appearance of a three-axis linkage numerical control processing system, the more advanced thread processing mode, namely the numerical control milling of the threads, is realized. Compared with the traditional thread machining mode, the thread milling machining has great advantages in machining precision and machining efficiency, and is not limited by a thread structure and a thread rotation direction during machining. For example, a thread milling cutter can process internal threads and external threads with different rotation directions, and for threads which are not allowed to have a transitional buckle or tool withdrawal groove structure, the threads are difficult to process by adopting a traditional turning method or a tap and a die, but are quite easy to realize by adopting numerical control milling. In addition, the durability of the thread milling cutter is tens of times or even tens of times of that of a screw tap, and in the process of numerical control thread milling, the adjustment of the diameter size of the screw thread is extremely convenient, which is difficult to achieve by adopting the screw tap and a screw die, and the milling process is widely adopted for mass thread production at present due to the advantages of thread milling.

The existing single-tooth thread milling cutter is used for milling threads, the thread milling cutter is generally of an integral design, the high-temperature oxidation resistance and the wear resistance of the thread milling cutter are easy to be reduced after the thread milling cutter works for a long time, the milling precision of the threads is reduced after a blade is worn, the precision requirement cannot be met, and the milling cutter needs to be replaced. When the milling cutter is replaced, the whole milling cutter is required to be replaced, and the cutter handle and the cutter bar which are not worn cannot be used, so that the production cost is increased, and meanwhile, the waste of resources is caused.
