Thread milling cutter structure

Abstract

The invention discloses a thread milling cutter structure, which comprises a main shaft, a rotating body, a block, a cutting and milling plate, a cutting and milling thread, a pointer, a fixed block, a connecting bolt, an adjusting bolt, a scale, a friction block, an adjusting groove, and a material guide groove and snap slots. The main shaft of the present invention is provided with a symmetrical clamping groove, which can be clamped with the installation interface, and the device can effectively prevent the rotation in the horizontal direction during the rotation process. It is fixed with the rotating body through the fixed block, and the milling plate is connected with the rotating body. Different types of cutting plates can be replaced to cut and mill threads of different types and diameters. There is a pointer on the cutting plate corresponding to the scale on the fixed plate. Cooperate to facilitate the adjustment of the position of the cutting board. There is an adjustment groove on the cutting board. The adjusting groove cooperates with the adjusting bolt. After the cutting board is fine-tuned, further fixing is carried out, which effectively improves the fixing strength of the cutting board.

Description

technical field [0001] The invention relates to a thread milling cutter, in particular to a thread milling cutter structure, belonging to the field of machining cutting tools. Background technique [0002] The traditional thread processing method is mainly to use a thread turning tool to turn the thread or to use a tap, a die to manually tap and buckle. With the development of CNC machining technology, especially the emergence of three-axis linkage CNC machining system, a more advanced thread processing method - CNC milling of threads can be realized. Compared with traditional thread processing methods, thread milling has great advantages in processing accuracy and processing efficiency, and is not limited by thread structure and thread rotation during processing. For example, a thread milling cutter can process a variety of different rotation directions. Internal and external threads. For threads that do not allow a transition buckle or undercut structure, it is difficult...

AI Technical Summary

Problems solved by technology

[0003] The traditional tap processing thread not only has poor processing quality, poor finish, and difficult to control the middle diameter size, but also the tap is easy to wear and break during the thread processing process, resulting in the scrapping of the workpiece or high manufacturing cost of the workpiece. The tool is easy to vibrate when threading the hole, and the uneven wear of the blade causes the processed product to be prone to taper. At the same time, the processing range of the blade in this processing method is relatively simple, so they are difficult to meet the needs of the current processing industry. Ordinary thread milling cutters cannot It is difficult to meet various thread processing needs by changing the type of thread to be processed
