The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 9, screw axial clamped-in style detachable blade Steel Plate Guide Drill in the present embodiment comprises handle of a knife 6, cutter hub 1, at least three screws 3 that blade 2 is identical with blade 2 with quantity, in the utility model, the quantity of blade 2 can arrange according to actual needs, generally, the quantity of blade 2 is 3-15.
The present embodiment is provided with a screw hole 12 in the bottom of each insert groove 11, this screw hole 12 is blind hole shape structure, and the shape of screw hole 12 and size all are complementary with screw 3, the direction of the screw hole 12 in the present embodiment is identical with the axial direction of cutter hub 1, and namely screw hole 12 is vertical shape structure.Bottom at insert groove 11 also is provided with locating slot 4, and this locating slot 4 can be v-shaped structure or trapezium structure.
The present embodiment is provided with blade 21 at the top of blade 2, is provided with connecting through hole 22 in blade 2, and the shape of this connecting through hole 22 and size all are complementary with screw 3.
The utility model changes to interchangeable blade with welding blade on the basis of former blade welding steel twist drill, this drilling tool is to adopt the ring-type cutting, at the cylindrical place of cutter hub 1, some chip areas 5 is set, and is cutting edge at the end face of chip area 5.This drilling tool is axially fixed in blade 2 on cutter hub 1 by screw 3, and after blade 2 was fixing, the front of blade 2 and back were the cutting faces, so expose to outside the end face of cutter hub 1; Blade 2 adopts the location structure design with cutter hub 1 contact-making surface, and as V-arrangement contact or flute profile contact, blade 2 just can better be realized the accurate resetting on cutter hub 1 like this.The utility model after blade 2 lost efficacy, can be changed the blade 2 of inefficacy by screw 3 axial restraint blades 2 easily, and cutter just can be reused, and has reduced client's consuming cost; Blade 2 adopts interchangeable blade, makes the shape of cutter and precision more guaranteed, and performance is more stable when production and application.
