Description
Technical field
The utility model is related to drill bit cutter heads, and in particular to a kind of embedded Integral alloy cutter head.
Background technology
Electric hammer drill mainly uses superior alloy steel, is matched with various electric hammers, is suitable in hard such as concrete, bricks
It drills on building materials, is mainly used to process through-hole or blind hole, and carry out reaming on the basis of hole, be building, peace
Fill a kind of multipurpose, efficient boring bar tool in industry.Alloy cutter head on existing electric hammer drill generally passes through welding
Mode is connected with cutter head, and welding manner is mainly by two kinds：One is blade inserting welding, this welding manner difficulty is small, but
The big object of hardness is encountered during use, cutter head is easy avalanche；One is whole butt-joints to connect, and drill bit head connects with cutter head face face
It touches, but this welding technique difficulty is big, positioning process is cumbersome, and welding cost is high.
Utility model content
In order to solve the problems in the existing technology, the utility model provides a kind of embedded Integral alloy cutter head,
Have the characteristics that at low cost, welding is quick and easy.
The technical solution that the utility model solves the above problems is：A kind of embedded Integral alloy cutter head, including drill bit shaft
Body, cutter head, cutter head bottom are equipped with root of the tooth, and drill bit body of rod top is equipped with groove, and cutter head is embedded in groove with the drill bit body of rod by root of the tooth
It is inside weldingly connected, cutter head chip space is aligned with drill bit body of rod chip space and is connected to.
The cutter head is a word cutter head, and for root of the tooth in the "-" type that is projected as of horizontal plane, groove is projected as one horizontal plane
Font.
The cutter head is cross cutter head, and root of the tooth is projected as cross horizontal plane, and groove is projected as ten horizontal plane
Font.
The trench cross section shape is rectangle.
The trench cross section shape is coniform.
The utility model has advantageous effect：The utility model accomplishes that drill bit head integrally closes by embedded welding procedure
Golden welding job；The utility model accurate positioning, it is convenient and efficient, alloy cutter head position is fixed by the groove of drill bit body of rod plane
It sets, drill bit front working portion Integral alloy, no bar structure, improves bit bore service life and wearability；Pass through cutter head bottom
Root of the tooth designs, and embedded drill bit shaft body groove welding increases bonding area, improves weld strength, while realizing drill bit head
Portion's Integral alloy work, substantially increases the bit bore service life；The utility model is convenient for head alloy cutter head various types and tooth
Shape is designed and developed, and for extraordinary drilling demand, can more be made the most of the advantage, low cost, quick and easy.

The body of rod 1 is embedded in groove 4 by root of the tooth 3 and is weldingly connected, and a word cutter head chip space 5 is aligned with drill bit body of rod chip space 6 to be connected to.
Embodiment two
A kind of embedded Integral alloy cutter head, including the drill bit body of rod 1, cross cutter head 7,7 bottom of cross cutter head are equipped with root of the tooth
3,1 top of the drill bit body of rod is equipped with groove 4, and root of the tooth 3 is cross, cross cutter head 7 and drill bit in the projection of horizontal plane with groove 4
The body of rod 1 is embedded in groove 4 by root of the tooth 3 and is weldingly connected, and cross cutter head chip space 8 is aligned with drill bit body of rod chip space 7 and is connected to.
The utility model accomplishes drill bit head Integral alloy welding job by embedded welding procedure；The utility model is fixed
Level is true, convenient and efficient, and alloy cutter head position is fixed by the groove 4 of 1 plane of the drill bit body of rod；It is set by cutter head bottom root of the tooth 3
Meter, embedded 1 groove 4 of drill bit shaft body weld, increase bonding area, improve weld strength, while it is whole to realize drill bit head
Body alloy works, and substantially increases the bit bore service life；The utility model is convenient for head alloy cutter head various types and tooth form
It designs and develops, for extraordinary drilling demand, can more make the most of the advantage, low cost is quick and easy.
Many other changes and modifications may be made without departing from the spirit and scope of the utility model.It should be appreciated that this reality
It is not limited to specific embodiment with novel, the scope of the utility model is defined by the following claims.
