Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: a numerical control slotting tool with a fillet comprises a tool shank 1, a tool neck 2 and a tool bit 3, a plurality of moving blocks 5 are arranged on the circumference of the side end face of the tool shank 1, the extending ends of the moving blocks 5 are all arc-shaped structures, used for being connected with the cutter neck 2 in a threaded manner, an elastic band 7 is arranged among a plurality of moving blocks 5, the convenience of the moving blocks 5 moving along the thread grooves 4 is improved, a plurality of groups of thread grooves 4 are arranged on the side end surface of the cutter handle 1 corresponding to the positions of the moving blocks 5, the plurality of groups of thread grooves 4 are respectively and linearly distributed on the central axis of the corresponding moving blocks 5, and each set of thread grooves 4 is on the same circumference, so that when a plurality of moving blocks 5 can move inwards or outwards at the same time, the extending ends of the moving blocks 5 are located on the same circumferential line, bolts 6 penetrate through the inside of the moving blocks 5, and the bolts 6 are in threaded connection with the thread grooves 4, so that fixing of each moving block 5 is achieved.

Specifically, as shown in fig. 1, the side walls of the extending ends of the moving blocks 5 are provided with threads, the tool necks 2 are screwed with the threads on the outer walls of the moving blocks 5, and the thickness of the moving blocks 5 is enough for screwing and fixing the tool necks 2.
