Description
Technical field：
The present invention relates to a kind of combined drill device with multistage drill bit, it is related to bit technique field.
Background technology：
Drill bit be on solid material drilling go out through hole or blind hole, and can be to the cutter of existing hole reaming.Conventional brill
Head mainly has fluted drill, chit drill, centre drill, depth drill and cylindrical drill.In the prior art, drill bit generally all uses hard alloy system
It is standby, but drill bits many at present is all single drill bit, thus it is inconvenient for step hole machined, practicality is not high.
The content of the invention：
The technical problems to be solved by the invention are：There is provided it is a kind of simple in construction, it is easy to use and effectively realize more drill bits combinations
The combined drill of processing step hole.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of combined drill device with multistage drill bit, including drilling rod, the first drill bit, the second drill bit and the 3rd drill bit, institute
The lower end for stating drilling rod is provided with resilient key, and first drill bit, the second drill bit, the 3rd drill bit are detachably connected and coaxially successively up and down
Set, and first drill bit, the second drill bit, the diameter of the 3rd drill bit diminish successively, the tail end of first drill bit be provided with
Its spliced eye being coaxially disposed, the spliced eye is interior to be provided with the pin-and-hole coordinated with resilient key.
The telescopic direction of the resilient key and the axis of drilling rod are vertically arranged, and the resilient key is arranged to semicircular plate-form knot
The axis of structure and its plate body along drilling rod is set.
The afterbody of second drill bit is provided with the second resilient key, and the head of first drill bit is provided with matches somebody with somebody with the second resilient key
The second spliced eye closed.
The afterbody of 3rd drill bit is provided with the 3rd resilient key, and the head of second drill bit is provided with matches somebody with somebody with the 3rd resilient key
The 3rd spliced eye closed.
First resilient key, the second resilient key, the structure of the 3rd resilient key are identical.
First drill bit, the second drill bit, the 3rd drill bit are arranged to high-speed steel drill, carbide drill or tungsten bur
Drill bit.
Compared with prior art, usefulness of the present invention is：The combined drill device with multistage drill bit is overall
Simple in construction, installation makes and easy to operate, and can realize the rapid processing in multi-stage stairs hole, thus practicality is high, is adapted to
Popularization and application.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the configuration schematic diagram of the present invention；
Fig. 2 is the side structure schematic diagram of the drilling rod of the present invention.
Embodiment：
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only
It is the part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
All other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention：
A kind of combined drill device with multistage drill bit as shown in Figure 1 and Figure 2, including drilling rod 1, the first drill bit 2, second bore
First 3 and the 3rd drill bit 4, the lower end of the drilling rod 1 is provided with resilient key 5, first drill bit 2, the second drill bit 3, the 3rd drill bit 4
It is detachably connected and is coaxially disposed successively up and down, and first drill bit, the second drill bit, the diameter of the 3rd drill bit diminish successively,
The tail end of first drill bit is provided with the spliced eye for being coaxial therewith setting, and the pin coordinated with resilient key is provided with the spliced eye
Hole.
In actual applications, stability when facilitating the quick grafting positioning of resilient key and improving its drilling, the bullet
Property the telescopic direction of pin and the axis of drilling rod be vertically arranged, the resilient key is arranged to semicircular plate-form structure and its plate body along boring
The axis of bar is set.
Further, it is connected for convenience of the second drill bit with the first drill bit, the afterbody of second drill bit is provided with the second elasticity
Pin 6, the head of first drill bit are provided with the second spliced eye coordinated with the second resilient key.
It is connected with the second drill bit for convenience of the 3rd drill bit, the afterbody of the 3rd drill bit is provided with the 3rd resilient key 8, and described the
