Drawings
In order to further explain the above objects, structural features and effects of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic view of the whole structure of a preferred embodiment of the present utility model;
FIG. 2 is a side view of FIG. 1;
in the figure: 1. a cutter head; 2. a knife handle; 3. a cutting blade; 4. chamfering blade; 5. a chip blocking block; 6. and (5) welding and plugging holes.
Detailed Description
The utility model is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
Referring to fig. 1 and 2, the main body of the small-diameter automatic chip breaking reamer is a reamer cutter body, and the reamer cutter body is a main part for connecting a machine tool spindle and a blade to bear reaming during cutting. The reamer comprises a cutter head 1 and a cutter handle 2 which are integrally connected, wherein cutting blades 3 which are distributed in a cross shape are radially distributed at the end part of the cutter head 1, the cutting blades 3 are used for cutting apertures, one sides, facing the cutter handle 2, of a pair of oppositely arranged cutting blades 3 are provided with chamfering blades 4, and the chamfering blades 4 are used for chip forming. A group of cutting edges 3 distributed in the axial direction of the cutter head 1 and the chamfering edge 4 share one chip groove, and the other two cutting edges 3 each use one chip groove alone. The cutting blade 3 is provided with a chip blocking block 5 on the same side in the circumferential direction of the cutter head 1, the chip blocking block 5 is a main component for controlling the chip removal direction and chip breaking when the cutting blade cuts, and the chip breaking after passing through the chip blocking block 5 is discharged into the nearest chip removal groove.
In the preferred embodiment, the cutting blade 3, the chamfering blade 4 and the chip blocking block 5 are all welded on the tool bit 1, and the center position of fig. 2 is a welding hole blocking 6. The chamfering blade 4 is located in the middle of the cutter head 1. Further, the end face of the chip blocking block 5 facing the direction of the cutter head 1 is a 45-degree chip breaking inclined plane.
According to the utility model, the chip blocking block with the inclined plane is welded on the cutting edge for generating chips, and different chip removal angles can be designed according to different material chemical compositions and material characteristics for rapid chip breaking during cutting, so that the structure is reasonable.
The foregoing is merely illustrative of the preferred embodiments of the present utility model and is not intended to limit the embodiments and scope of the present utility model, and it should be appreciated by those skilled in the art that equivalent substitutions and obvious variations may be made using the description and illustrations of the present utility model, and are intended to be included in the scope of the present utility model.
