Detailed Description

The embodiments are described in detail, clearly, and not in their entirety, it is to be understood that the embodiments described are only some of the embodiments of the present invention and are not to be taken as a complete description. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-6, the utility model provides a but little modulus transposition hobbing cutter, including knife rest 1 and blade 2, knife rest 1 includes arbor 3 and is an organic whole arbor sand grip 4 of being connected with arbor 3, arbor sand grip 4 is helical structure and is connected with arbor 3, the rigid coupling is equipped with on arbor sand grip 4 and inlays dress sword tooth 5, inlay dress sword tooth 5 side wall and seted up the screw, inclined hole 6 has been seted up to 2 side wall of blade, blade 2 inserts in the inclined hole 6 through mounting screw 7 and inlays dress sword tooth 5 and can dismantle the connection, when overhauling or grinding, through screwing out mounting screw 7, take off blade 2 can, can realize the convenience of dismouting.

Wherein, the 4 side wall surfaces of arbor sand grip and be located blade 2 one side and be connected with briquetting 11 through briquetting screw 8, realize the supplementary function that compresses tightly to blade 2 through briquetting 11, increase the connectivity of blade 2 and knife rest 1, prevent that the condition that blade 2 drops from taking place in the course of working.

The center of the cutter shaft 3 is provided with a through cutter shaft hole 9, the side wall surface of the cutter shaft hole 9 is provided with a groove 10, and the cutter shaft hole 9 and the groove 10 are used for inserting and connecting the cutter rest 1 and the driving device.
