The disassembly and assembly between the milling cutter head 2 and the milling cutter column 1 is convenient for replacement, and the situation that the one-piece single-edge T-type milling cutter needs to be replaced as a whole after damage is avoided can be avoided.

[0026] Working principle: When using the utility model, the milling cutter head 2 is connected to the end of the joint 101 on the milling cutter column 1 by sliding the limit groove 201, and a chip groove 203 is set between the single-edge seat 202 on the outer wall of the milling cutter head 2. According to the notch portion of the chip groove 203, the workpiece can be processed by the chip groove 203 during the cutting process. The above parts all adopt the existing single-edge T-type milling cutter, and the chip removal method is also set according to the chip removal method of the existing single-edge T-type milling cutter. By installing the mounting plate 3 according to the four mounting grooves 103 on the joint 101, the mounting plate 3 is connected to the joint 101. The guide post 301 is mounted and docked with the central part of the mounting plate 3 in a sliding manner. The arc head 302 and the positioning pin 303 are arranged at both ends of the guide post 301. When the guide post 301 slides horizontally left and right on the mounting plate 3, the arc head 302 and the positioning pin 303 can prevent the guide post 301 from being separated from the mounting plate 3. A spring A304 is arranged on the outer wall of the guide post 301. According to the effect of the elastic reaction force of the spring A304, the spring A304 keeps the arc head 302 reset on the joint 101. The T-slot 104 is provided with a plurality of screw threads, and the plurality of screw threads are connected to the T-slot 104. When the T-pin 4 is slidably docked in the T-slot 104, the T-pin 4 will squeeze the arc head 302 until it moves inward, so that the positioning pin 303 is inserted into the positioning groove 204 on the milling head 2, and the milling head 2 can be installed and fixed. The fastening bolt 402 is threadedly docked in the thread groove B401 on the T-pin 4, and during the installation of the fastening bolt 402, the spring B403 needs to be sleeved on the outer wall of the fastening bolt 402 before the installation is carried out. During the installation process, When the fastening bolt 402 is threadedly rotated into the thread groove A105 on the milling cutter column 1, the T-pin 4 can be installed and fixed. At the same time, the reaction force of the spring B403 can avoid the fastening bolt 402 from being reversed and loosened during operation after installation. The disassembly and assembly between the milling cutter head 2 and the milling cutter column 1 can facilitate their replacement and avoid the need to replace the entire one-piece single-edge T-type milling cutter after damage, effectively reducing a certain amount of processing costs and effectively improving the use effect of the single-edge T-type milling cutter.
