It is integrated, is dismantled by convenient, saved the drilling tapping time, improved production efficiency, reduce cost.
What the purpose of this utility model was realized in：A kind of detachable drilling and tapping integral type screw tap, including circular wire
Body is bored, one end of round tap body is provided with clamping part, and round tap body is divided into head end, middle-end and end, clamping part
The end of round tap body is arranged on, the head end of round tap body is also divided into front half section and second half section, and front half section is provided with
Drill bit, second half section are provided with screw tap, and drill bit and screw tap are fixed together, and chamfering, head end are provided between head end and middle-end
Diameter be less than middle-end diameter, middle-end is consistent with end diameter, is flexibly connected between middle-end and end, and middle-end is provided with spline
Set, end matching spline set are provided with spline, and spline is connected with spline housing.
During utility model works, operating personnel can directly use the integral type screw tap, and circle is clamped by fixture
The clamping part of screw tap body, after clamping, starts drilling and tapping, the integral type screw tap is first by drill bit to needing to punch
Product punched, punching carries out tapping while finish again, both are carried out at the same time, and improve production efficiency；One end drill bit
Or screw tap abrasion it is very fast when, operating personnel can directly disassemble spline and spline housing, and then take out head end and middle-end, then
The head end and middle-end of new integral type screw tap are changed, avoids clamping again through fixture, saves usage time, improves production effect
Rate.
The beneficial effects of the utility model are, a kind of detachable drilling and tapping integral type screw tap, can gather drilling and
Tapping is integrated, and is dismantled by convenient, has been saved the drilling tapping time, improved production efficiency, reduce cost.
As further improvement of the utility model, to ensure that it is smooth that the integral type screw tap is walked to consider to be worth doing；Set on the drill bit
Bits groove one is walked, bits groove two is provided with away on the screw tap, it is described to walk to consider groove one to be worth doing and walk to consider to be worth doing the ending connection of groove two.
As further improvement of the utility model, to ensure to avoid iron filings from scalding operating personnel；The head end and middle-end
Between be provided with chamfering, the chamfer angle is between 30 ° -60 °.
As further improvement of the utility model, clamped for guarantor's convenient to operate personnel；The clamping part axial direction milling
There are some clamping planes, two adjacent groups clamping plane is vertically arranged.
As further improvement of the utility model, to ensure that the integral type screw tap can be durable for a long time；The drill bit and
Screw tap is made of alloy material.
Brief description of the drawings
