Description

TECHNICAL FIELD

[0002] The internal thread processing tool is an important tool for machining threads in the workpiece inner hole, and is widely used in mechanical manufacturing, automobile, aerospace and other fields. The machining quality of internal thread directly affects the assembly accuracy and performance of parts, therefore, it is crucial to develop efficient, accurate and durable internal thread processing tool. The performance requirements of internal thread processing tool include cutting performance, precision, stability, shock resistance, thermal stability and other aspects. With the development of modern manufacturing technology, internal thread processing tool is continuously developing towards high efficiency, intelligence, automation and environmental protection and energy saving, in order to meet the increasingly improved industrial demand.

[0003] After searching, the existing patent (publication number: CN218050712U) discloses a threaded hole machining tool, which comprises a tool bar and a tool head, the tool head comprises a thread cutting part and a burr milling cutter part in sequence along the axial direction, wherein the thread cutting part is located at the end of the tool head and is used for machining the threaded hole, the thread cutting part comprises a plurality of cutting teeth which are equidistantly arranged along the axial direction and are arranged around the outer periphery of the tool head; the burr milling cutter part is located on the inner side of the thread cutting part and is connected with the thread cutting part, and is used for milling the burr of the threaded hole. The threaded hole machining tool of the utility model has the thread cutting part and the burr milling cutter part on the machining tool head, which are used for machining the threaded hole and milling the burr of the threaded hole respectively. After the thread cutting part completes the cutting and forming of the threaded hole, the burr milling cutter part immediately mills the burr of the threaded hole. Compared with the traditional internal thread machining method, the threaded hole machining tool provided by the utility model can greatly improve the machining efficiency of the threaded hole.

[0004] But in the actual use process of the above scheme, the tapping angle of the tool head is not adjustable, and the adjustment of the rotation angle of the tool head has a great influence on the precision, machining flexibility and tool life of the internal thread machining tool. First of all, different workpieces and materials require different cutting angles, and the inability to adjust the angle will limit the application range of the tool, resulting in unsatisfactory machining effect. In addition, the inability to adjust the angle may cause uneven distribution of cutting force, leading to accelerated tool wear and affecting machining efficiency and surface quality. After a long time of use, the tool wear cannot be compensated by adjusting the angle, thereby reducing the service life and machining stability of the tool. In summary, the unadjustable angle of the tool head will reduce the machining precision, affect the machining efficiency and accelerate the tool wear, limiting its application in high-precision and high-efficiency machining.

[0005] Therefore, the utility model provides an internal thread processing tool. UTILITY MODEL CONTENTS
