Abstract
The utility model is related to a kind of V-arrangement tooth diamond engineering thin wall drilling bits, its by the drill body of tubular, be set to the drilling machine connector of drill body one end and several arc cutter heads being distributed along drill body the other end face even circumferential are constituted, the top of the cutter head is the arc milling tooth of V-shaped section, and the height of the cutting tooth is equal with the thickness of cutter head.V-arrangement tooth diamond engineering thin wall drilling bit provided by the utility model is sharp durable, with boring positioning standard, drilling speed is fast, drilling hole amount is more, the high feature of drilling efficiency, and manufacture craft is simple, solves the deficiencies of existing bit bore location difficulty, drilling speed is slowly, drilling efficiency is low, drilling hole amount is few and defect.
Description
Technical field
The utility model is related to diamond bit, specifically a kind of V-arrangement 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 V-arrangement 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 V-arrangement tooth diamond engineering thin wall drilling bit by the drill body of tubular, is set to the brill of drill body one end
Machine connector and several arc cutter heads along the distribution of drill body the other end face even circumferential are constituted, and the top of the cutter head is V
The arc milling tooth of type section, and the height of the cutting tooth is equal with the thickness of cutter head.
The V-arrangement tooth diamond engineering thin wall drilling bit, one end that the drill body is connect with cutter head is cutd open along its axial direction
Face is T-type structure.
V-arrangement tooth diamond engineering thin wall drilling bit provided by the utility model is sharp durable, V-arrangement tooth tooth top and cutting point contact
Area is small, has boring positioning standard, also, the V-arrangement tooth of drill body upper cutter head forms circumferential cutting edge, and drilling speed is fast,
Drilling hole amount is more, the high feature of drilling efficiency, and manufacture craft is simple, solves existing bit bore location difficulty, drilling speed
The deficiencies of degree is slow, drilling efficiency is low, drilling hole amount is few and defect.
Description of the drawings
Fig. 1 is the utility model cross-sectional view in an axial direction.
Fig. 2 is the tool bit part structural schematic diagram of the utility model.
Fig. 3 is the cutter head dimensional structure diagram of the utility model.
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, V-arrangement tooth.
Specific implementation mode
As shown in Figure 1, the V-arrangement 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 Figure 2 and Figure 3, cutter head 3 is arc-shaped, and cutter head 3 is by metal powder and diamond
Particle is made, along the end face even circumferential distribution of the T-type boss 7 of drill body 2.The top of cutter head 3 is V-arrangement tooth 8, V-arrangement tooth 8
For the V-shaped arc milling tooth of section, height is equal with the thickness of cutter head 3.
Claims (2)
1. a kind of V-arrangement tooth diamond engineering thin wall drilling bit, by the drill body of tubular, it is set to the drilling machine of drill body one end
Connector and several arc cutter heads along the distribution of drill body the other end face even circumferential are constituted, characterized in that the cutter head
Top is the arc milling tooth of V-shaped section, and the height of the cutting tooth is equal with the thickness of cutter head.
2. V-arrangement tooth diamond engineering thin wall drilling bit according to claim 1, characterized in that the drill body and cutter head
One end of connection is T-type structure along its axial section.
