Abstract
The invention discloses an auger drill with a replaceable blade. The auger drill comprises an auger drill stem, wherein a blade installation groove is formed between notches at front ends of two spiral chip removal grooves transversely; the lower half part of the blade installation groove is provided with a V-shaped groove bottom with an amplified angle; a locking hole is formed on two side walls of the V-shaped groove bottom; a countersunk head screw hole is formed on one side of the locking hole, and an aperture is formed on the other side of the locking hole; a blade is in full matching in the blade installation groove; a rotary-cut cutting edge is formed on the upper end face of the blade; a positioning body matched with the V-shaped groove bottom is arranged on the lower part of the blade; a through hole is formed on the positioning body corresponding to the locking hole; and a countersunk head screw which extends into the through hole of the blade and the aperture on the other side is arranged in the locking hole. In the auger drill, the conventional drill with integrated drill stem and blade is changed into a structure with the replaceable blade, so the trouble of grinding the cutting edge is saved, the service life is prolonged, the cost is reduced, and materials are saved.
Description
Technical field:
The present invention relates to drill bit, particularly a kind of spiral bit of changeable blade.
Background technology:
Existing spiral bit, the cutting blade of its head and drilling rod all are overall structures, and blade can't be changed; After the blade wearing and tearing, can only carry out sharpening by hand, general blade can only be refaced for several times; Cause the service life of drill bit short, working (machining) efficiency is low, waste material and cost.
Summary of the invention:
The purpose of this invention is to provide a kind of long service life, working (machining) efficiency is high, saves the spiral bit of the changeable blade of cost and material.
Technical scheme of the present invention is accomplished as follows; It comprises a twist drill rods; It is characterized in that: between the notch of two helical flute front ends on the drilling rod, laterally have a blade installation slot; The Lower Half of blade installation slot is at the bottom of the V-shaped groove of an amplification angle; On the two side at the bottom of the V-shaped groove, be provided with a locking hole; One side of locking hole is the countersunk head screw; Opposite side is a unthreaded hole; In blade installation slot, completely be combined with a blade; It on the blade upper surface rotary-cut blade; The blade bottom be one with the positioning body that matches at the bottom of the V-shaped groove; On positioning body, be provided with through hole, be installed on a countersunk head screw that is deep in insert through hole and the opposite side unthreaded hole in the locking hole with the locking hole relevant position.
The present invention is the structure that the conventional drill of one changes changeable blade into drilling rod and blade, has saved the trouble of sharpening, has improved service life, helps reducing cost and saving material.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is the structural representation of drilling rod of the present invention.
Fig. 3 is the structural representation of blade of the present invention.
The specific embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail; The present invention is processed into drilling rod 2 and 5 two parts of blade with existing spiral bit; Between the top notch of two spirality chip areas 1 of drilling rod, have a horizontal blade installation slot 4 downwards; The Lower Half of blade installation slot is at the bottom of the V-shaped groove of an amplification angle; On the two side at the bottom of the V-shaped groove, be provided with a locking hole 3; One side of locking hole is the countersunk head screw; Opposite side is a unthreaded hole; In blade installation slot, completely be combined with a blade 5; It on the blade upper surface rotary-cut blade 6; The bottom be one with the positioning body that matches at the bottom of the V-shaped groove; On positioning body, be provided with through hole with the locking hole relevant position; Be installed on a countersunk head screw 8 that is deep in insert through hole 7 and the drilling rod opposite side unthreaded hole in the locking hole, be screwed onto countersunk head screw in the locking hole during installation, the countersunk head screw polished rod gets final product blade pressing is fixing.It is convenient to have replacing blade simple in structure, the advantage of long service life.
