Description

Technical Field

[0001] The utility model relates to the technical field of thread milling cutters, in particular to a composite processing thread milling cutter. Background Art

[0002] Traditional thread processing methods mainly use thread turning tools to turn threads or use taps and dies for manual tapping and threading. With the development of CNC machining technology, especially the emergence of three-axis CNC machining systems, a more advanced thread processing method, CNC milling of threads, has been realized. Compared with traditional thread processing methods, thread milling has great advantages in processing accuracy and efficiency, and is not restricted by thread structure and thread rotation direction during processing. For example, a thread milling cutter can process internal and external threads of various rotation directions. For threads that do not allow transition buckles or back-cut groove structures, it is difficult to process them using traditional turning methods or taps and dies, but it is very easy to achieve using CNC milling. In addition, the durability of thread milling cutters is more than ten times or even dozens of times that of taps, and in the process of CNC milling threads, it is extremely convenient to adjust the thread diameter size, which is difficult to do using taps and dies.

[0003] However, during the use of the existing composite processing thread milling cutter, when the thread milling cutter processes the workpiece, friction will be generated between the thread milling cutter and the inner wall of the workpiece, and the thread milling cutter will generate heat after the friction. Since the thread milling cutter cannot cool down the workpiece, the thread milling cutter will burn out or break after a long period of processing, resulting in a short service life of the thread milling cutter. For this reason, we have designed a composite processing thread milling cutter to solve the above problems. Summary of the invention

The top of the connecting tube 4 is fixedly connected to the lubrication tube 5. The lubrication tube 5 is connected to the damaged equipment so that the lubricating fluid can be quickly transported to the thread milling cutter.

[0023] Among them, four drainage chambers 12 are provided, and the four drainage chambers 12 have the same size. The four drainage chambers 12 have the same size, and the lubricating liquid can be discharged evenly through the drainage chambers 12, so as to play a comprehensive lubricating role.

[0024] More specifically, a plurality of thread profile angles 9 are provided, and the plurality of thread profile angles 9 are divided into four groups, and the four groups of thread profile angles 9 are arranged equidistantly, and the thread profile angles 9 can be used to quickly perform thread processing on holes on a workpiece.

[0026] In this embodiment, the cutter body 8 and the thread profile angle 9 are both made of alloy material. The cutter body 8 and the thread profile angle 9 are an integrated structure. The cutter body 8 and the thread profile angle 9 made of alloy material are more sturdy and durable.
