Detailed Description

As shown in the figure, the utility model discloses a special slotting tool of vertical machining center, include casing 1 and install immediately with main epaxial slotting tool 2, the slotting tool includes handle of a knife 3, handle of a knife locating piece 10, die-cutting board 9 and cutter, be equipped with the screw hole on the handle of a knife locating piece, including screw hole II8 and screw hole III 13. The knife handle is sequentially provided with a circular truncated cone 3-1, a boss 3-2, a cylinder I3-3, a cylinder II3-4 and a cylinder III3-5 from front to back and is integrally formed. The diameter of the boss is larger than the diameter of the bottom of the circular truncated cone and the diameter of the cylinder I. The tool holder positioning block is characterized in that a positioning hole 12 is formed in the tool holder positioning block 10, the positioning hole penetrates through the circular truncated cone and the boss and is installed at the position of the cylinder I, a tool holder compensation ring 5 is installed between the tool holder positioning block and the cylinder I, the tool holder compensation ring is two mutually symmetrical semicircles, and the tool holder positioning block is fixedly connected with the tool holder through tightening bolts in the threaded holes III. The diameter of the cylinder II is larger than that of the cylinder I and smaller than that of the cylinder III, the end part of the cylinder III is provided with four threaded holes I7 and a cutter groove 11, the four threaded holes correspond to the four threaded holes in the cutter pressing plate, and the four bolts penetrate through the four threaded holes respectively to fixedly connect the cutter pressing plate with the cutter handle. The cutter 6 is installed at the cutter groove, the cutter handle positioning block is installed in the middle of the cutter handle, the cylindrical pin hole 4 is formed in the cutter handle positioning block and used for installing a cylindrical pin, the installation direction of the cylindrical pin is the same as the installation direction of the cutter handle, and the cutter is aligned with the center of the tool through the cylindrical pin and used for positioning.
