[0002] A thread cutting tool holder is a tool rack or support used to fix and support the cutting tool or workpiece during thread machining. Its main function is to ensure the stability, accuracy, and cutting efficiency of the cutting tool during machining. The design and use of the thread cutting tool holder directly affect machining quality, tool life, and machining efficiency.

This patent employs a base and a preparation equipment body. A top plate is fixedly connected to the base via two support plates. The top plate is equipped with an adjustment mechanism for adjusting the position of the preparation equipment body. A mounting plate is rotatably connected to the left support plate, and the left support plate is equipped with a first power mechanism for providing the power required for the rotation of the mounting plate. The mounting plate has a placement groove, in which the cutting tool to be processed is placed. Three U-shaped guide plates are fixedly connected to the mounting plate, and the U-shaped guide plates are equipped with clamping mechanisms for clamping the cutting tool to be processed. The mounting plate is equipped with a transmission mechanism for providing the power required for the clamping mechanisms. This utility model has a reasonable structure, good clamping effect, no deviation during the preparation process, high processing accuracy, and can automatically rotate the thread cutting tool, resulting in high processing efficiency.
