Abstract

The invention discloses an improved hollow drill which comprises a pipe-shaped base body, cutting teeth and a linkage part, wherein the cutting teeth are arranged at the bottom of the pipe-shaped base body; the linkage part is positioned in the pipe-shaped base body; a gear-shaped linkage hole is formed in the center of the linkage part; the outer peripheral wall of the pipe-shaped base body is provided with an annular groove; and the linkage hole is communicated with the linkage groove. The improved hollow drill can be manufactured into an integral compound drill together with a plastic drill handle and an auger positioning bit through an integrated injection molding mode, so that the strength is ensured, and the manufacturing cost of the compound drill is effectively reduced.

Description

A kind of modified form hollow boring bit
Technical field
Drill bit structure design field of the present invention is specifically related to a kind of modified form hollow boring bit.
Background technology
Accompanying drawing 1 is a kind of cutaway view of conventional drill, and this kind drill bit comprises 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 external screw thread connecting portion (912), and drillstock handle body is provided with the fastener hole (913) that is communicated with blind hole; Described hollow boring bit is spirally connected on the external screw thread connecting portion that is fixed on drillstock, and an end of described fluted drill is arranged in the drillstock blind hole as stiff end, and the other end stretches out this blind hole and exceeds hollow boring bit as the cutting end; Described trip bolt is arranged in the drillstock fastener hole, and the stiff end of fluted drill is pressed abd fixed in the blind hole.
The weak point of this conventional drill is: its structure is comparatively complicated, and the processing and manufacturing operation is comparatively loaded down with trivial details; Its drillstock, drill bit and fluted drill all are to adopt metal to make in addition, and weight is heavier, and cost is higher.
Summary of the invention
It is comparatively reasonable to the purpose of this invention is to provide a kind of structure, can effectively reduce the modified form hollow boring bit of composite drill bit manufacturing cost.
The technical scheme that realizes the object of the invention is: a kind of modified form hollow boring bit comprises tubular matrix, is arranged on the cutting teeth of tubular matrix bottom and is positioned at the linkage portion of tubular matrix; Described linkage portion center is provided with gear-like interlock hole; Described tubular matrix periphery wall is provided with an annular groove, and described interlock hole is communicated with this annular groove.
The present invention can with plastics drillstock and fried dough twist location drill bit by integrated injection molding mode all-in-one-piece composite drill bit processed, can proof strength, can effectively reduce again the manufacturing cost of composite drill bit.
Description of drawings
Fig. 1 is a kind of structural representation of conventional drill;
Fig. 2 is a kind of perspective view of the present invention;
The perspective view of Fig. 3 when to be hollow boring bit shown in Figure 2 from another angle observe;
Fig. 4 is the structural representation that adopts a kind of composite drill bit that hollow boring bit shown in Figure 2 makes;
Fig. 5 is a kind of explosive view of composite drill bit shown in Figure 4;
A kind of explosive view of Fig. 6 when to be composite drill bit shown in Figure 4 from another angle observe.
The specific embodiment
(embodiment 1)
Fig. 2 and Fig. 3 have shown a kind of specific embodiment of the present invention, and wherein Fig. 2 is a kind of perspective view of the present invention; The perspective view of Fig. 3 when to be hollow boring bit shown in Figure 2 from another angle observe.
Present embodiment is a kind of modified form hollow boring bit, sees Fig. 2 to shown in Figure 3, comprises tubular matrix 21, is arranged on the cutting teeth 22 of tubular matrix 21 bottoms and is positioned at the linkage portion 23 of tubular matrix 21; Described linkage portion 23 centers are provided with gear-like interlock hole 24; Described tubular matrix 21 periphery walls are provided with an annular groove 25, and described interlock hole 24 is communicated with this annular groove 25.
(application examples 1)
Fig. 4 to Fig. 6 has shown a kind of concrete application mode of the present invention, and wherein Fig. 4 is the structural representation that adopts a kind of composite drill bit that hollow boring bit shown in Figure 2 makes; Fig. 5 is a kind of explosive view of composite drill bit shown in Figure 4; A kind of explosive view of Fig. 6 when to be composite drill bit shown in Figure 4 from another angle observe.
Should use-case be a kind of composite drill bit that adopts above-described embodiment 1 to make, see that Fig. 4 is to shown in Figure 6, comprise drillstock 1, hollow boring bit 2 and spiral bit 3, described hollow boring bit 2 and spiral bit 3 adopt metal to make, spiral bit 3 and hollow boring bit 2 are arranged on drillstock 1 same end, and spiral bit 3 is positioned at hollow boring bit 2 centers; Described hollow boring bit 2 comprises tubular matrix 21, be arranged on the cutting teeth 22 of tubular matrix 21 bottoms and be positioned at the linkage portion 23 of tubular matrix 21; Described spiral bit 3 comprises the fixed part 31 that links to each other with drillstock 1 and away from the cutting portion 32 of drillstock 1; Described drillstock 1 adopts plastics to make, and comprises the injection moulding connecting portion 11 that links to each other with hollow boring bit 2 and away from the installation portion 12 of hollow boring bit 2 one ends; The fixed part 31 of described spiral bit 3 and the linkage portion of hollow boring bit 2 23 and this injection moulding connecting portion 11 are fixedly linked by injection molding, and the cutting portion 32 of spiral bit 3 is positioned at the center of hollow boring bit 2 tubular matrix 21 and exceeds the cutting teeth 22 of hollow boring bit 2.
The center of described hollow boring bit 2 linkage portion 23 is provided with gear-like interlock hole 24; The injection moulding connecting portion 11 of described drillstock 1 is provided with the linkage gear 13 that matches with this interlock hole 24.
Described drillstock 1 also is provided with at the two ends of its linkage gear 13 for two in hollow boring bit 2 linkage portion 23 the are encapsulated in circular shroudings 15 that strengthen, described enhancing shrouding 15 is arranged in hollow boring bit 2 tubular matrix 21 endoporus, described linkage gear 13 strengthens between the shrouding 15 two, and the up and down two ends of each gear teeth link to each other with two enhancing shroudings 15 respectively on the linkage gear 13.
