Description
Technical field
Drill bit structure design field of the present invention, is specifically related to a kind of modified model drill bit.
Background technology
Accompanying drawing 1 is the sectional view of a kind of conventional drill, and this kind of drill bit includes drillstock (91), hollow boring bit (92), fluted drill (93) and trip bolt (94); The center of described drillstock one end is provided with blind hole (911), and the periphery wall of this end is provided with male threaded joint (912), and drillstock shank body is provided with the fastener hole (913) connected with blind hole; Described hollow boring bit is spirally connected on the male threaded joint being fixed on drillstock, and one end of described fluted drill is arranged in drillstock blind hole as fixing end, and the other end stretches out this blind hole as cutting end and exceeds hollow boring bit; Described trip bolt is arranged in drillstock fastener hole, and the fixing end of fluted drill is pressed abd fixed in blind hole.
This conventional drill is disadvantageous in that: its structure is complex, and processing and manufacturing operation is relatively complicated; Additionally its drillstock, drill bit and fluted drill are all adopt metal to make, heavier-weight, and relatively costly.
Summary of the invention
It is an object of the invention to provide the modified model drill bit of a kind of effective reduction manufacturing cost.
The technical scheme realizing the object of the invention is: a kind of modified model drill bit, including drillstock, hollow boring bit and spiral bit, described hollow boring bit and spiral bit adopt metal to make, and spiral bit and hollow boring bit are arranged on the same one end of drillstock, and spiral bit is positioned at hollow boring bit center; Described hollow boring bit includes tubular matrix, is arranged on the cutting tooth of tubular matrix bottom and is positioned at the linkage portion of tubular matrix; Described spiral bit includes the fixed part that is connected with drillstock and the cutting portion away from drillstock; Described drillstock is adopted made of plastic, including the injection moulding connecting portion being connected with hollow boring bit with away from the installation portion of hollow boring bit one end; The fixed part of described spiral bit and the linkage portion of hollow boring bit are fixedly linked by injection molding with this injection moulding connecting portion, and the cutting portion of spiral bit is positioned at the center of hollow boring bit tubular matrix and exceeds the cutting tooth of hollow boring bit.
The present invention adopts drillstock made of plastic, it is possible to obtain the technique effect same with conventionally employed metal drill bit, and owing to material price is cheap, production efficiency is higher, thus effectively reducing manufacturing cost.
