Description
Technical field
The utility model is related to diamond bit, specifically a kind of saw-shaped tooth diamond engineering thin wall drilling bit.
Background technology
Diamond engineering thin wall drilling bit is simple in structure, has high intensity, high abrasion and shock proof boring capacity, main to use
In the drilling of reinforced concrete, stone material, refractory brick and bituminous paving.
Currently, be both at home and abroad plane at the top of the cutter tooth of the diamond thin-wall drill bit of engineering the drilling and interior outside,
This at work, drill bit with it is big by the contact area of drilling object, larger pressure and higher drilling machine work(are needed in drilling process
Rate, thus labor intensity is big, working efficiency is low when leading to drilling.In addition, since tooth top is mostly plane, existing diamond bit is more
There are location difficulty, the slow-footed defects of drilling.
Utility model content
The purpose of this utility model is to provide a kind of saw-shaped tooth diamond engineering thin wall drilling bit, is flat to solve existing tooth top
The problem that face structural diamond drill bit positioning is inaccurate, drilling speed is slow, drilling efficiency is low.
What the purpose of this utility model was realized in：
A kind of saw-shaped tooth diamond engineering thin wall drilling bit by the drill body of tubular, is set to drill body one end
Drilling machine connector and several arc cutter heads along the distribution of drill body the other end face even circumferential are constituted, the cutting end of the cutter head
For the broached-tooth design being made of several zigzag boss, the zigzag boss is crossing cutter head intrados or extrados axial centerline
Section on be projected as up-narrow and down-wide ladder structure of right angle.
The saw-shaped tooth diamond engineering thin wall drilling bit, between adjacent saw-tooth shape boss between be separated with chip removal gap.
The saw-shaped tooth diamond engineering thin wall drilling bit, one end end that the drill body is connect with cutter head is along its axis
It is T-type structure to section.
Saw-shaped tooth diamond engineering thin wall drilling bit manufacture craft provided by the utility model is simple, sharp durable, zigzag
Contact area is small between boss top and cutting site, to unit area compression great efforts so that bit bore positioning is accurate, separately
Outside, the design of jagged cutting head and chip removal gap, makes in boring procedure that drilling speed is fast, and drilling hole amount is more, and drilling efficiency is high,
The deficiencies of chip removal faster, solves existing bit bore location difficulty, and drilling speed is slow, drilling efficiency is low, drilling hole amount is few and
Defect.

In figure：1, drilling machine connector, 2, drill body, 3, cutter head, the 4, first screw thread, the 5, second screw thread, 6, third screw thread, 7,
T-type boss, 8, zigzag boss, 9, chip removal gap, 10, right angle waist.
Specific implementation mode
As shown in Figure 1, the saw-shaped tooth thin faced bit of the utility model is made of three parts, it is respectively that drilling machine connects
First 1, drill body 2 and several cutter heads 3.In Fig. 1, the right end of drilling machine connector 1 is hexagon, is provided centrally with and engineering driller
First screw thread 4 of connection；The left end outer wall of drilling machine connector 1 is equipped with the second screw thread 5 being connect with drill body 2.Drill body 2
Right end inner wall is equipped with the third screw thread 6 coordinated with the second screw thread 5 of drilling machine connector 1, and the second screw thread 5 makes with the assembly of third screw thread 6
To transmit torque, the left end of drill body 2 has round ring boss, and the inside and outside circular diameter of round ring boss is than drill body 2
Inside and outside circular diameter is 0.5-1 millimeters big, and thickness is 2-3 millimeters, i.e., the left end end of drill body 2 is that T-type is convex along its axial section
Platform 7.
5 cutter heads 3 are shared in this example, as shown in Fig. 2, cutter head 3 is arc-shaped, cutter head 3 is by metal powder and diamond particles
It is made, along the end face even circumferential distribution of the T-type boss 7 of drill body 2.3 top of cutter head（That is cutting end）To be sawed by three
The zigzag structure that dentation boss 8 is constituted, zigzag boss 8 is on the section for crossing 3 intrados of cutter head or extrados axial centerline
Be projected as up-narrow and down-wide ladder structure of right angle（Referring to Fig. 3）, chip removal gap 9, sawtooth are installed between adjacent saw-tooth shape boss 8
The height of the height of shape boss 8（That is the right angle waist 10 of right-angled trapezium）It it is 1.5-2.5 millimeters, zigzag boss 8 is along rotation clockwise
It is from high to low to turn direction.
For this saw-shaped tooth thin drilling bit in boring procedure, cutting site can be accurately positioned in zigzag boss 8, ensure drill bit
It does not misplace, and since tip contact area is small, per unit contact area pressure is big, to keep drilling speed fast, efficient, in addition saws
Chip removal is smooth during the inclined-plane and chip removal gap 9 of dentation boss 8 ensure drilling.
