Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-5, the hard alloy milling cutter with high toughness and high smooth surface in the present embodiment includes a cutter body 1, a titanium coating 6 is disposed on an outer wall of the cutter body 1, a cutter head 8 is disposed at a top end of the cutter body 1, and thread grooves 7 are uniformly formed on an outer wall of the cutter head 8.

The bottom of cutter body 1 is provided with connecting rod 2, and the bottom of 2 outer walls of connecting rod is provided with lag 4, and the bottom of cutter body 1 is provided with fixed knot and constructs 3.

Referring to fig. 1 and 5, in the present embodiment, the fixing structure 3 includes a clamping rod 302, the clamping rod 302 is installed at a middle position of the bottom end of the cutter body 1, a mounting groove 301 is correspondingly formed at the top end of the connecting rod 2 below the clamping rod 302, and a rubber ring 303 is installed at the bottom end inside the mounting groove 301.

It should be noted that, by inserting the clamping rod 302 into the mounting groove 301, the clamping rod 302 is ensured to be stable by the arrangement of the rubber ring 303.

Referring to fig. 1 and 5, in the embodiment, an inner cavity 12 is formed at the lower end of the inside of the clamping rod 302, sliding plates 15 are slidably connected to both sides of the inside of the inner cavity 12, a protruding rod 9 is installed at one side of each sliding plate 15, and a limit hole 11 is correspondingly formed in the side wall of the connecting rod 2 at one side of the protruding rod 9.
