Description
Technical field
The utility model belongs to field of mechanical technique, is related to tooth-implanting grinding and bores.
Background technology
Grinding is using coating or is press-fitted the abrasive grain on lap tool, is bored by grinding with work piece in certain pressure
Under the finished machined that is carried out to finished surface of relative motion.Grinding can be used for processing various metals and nonmetallic materials, process
Surface configuration have plane, the inside and outside face of cylinder and circular conical surface, convex, concave spherical surface, screw thread, the flank of tooth and its alloytype face.
Also have grinding step in tooth operation process is planted, above-mentioned operation be typically corresponding to lapping device come operation
Realize.
Lapping device is complicated, and cost is higher.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, there is provided a kind of stability is high and structure is tight
The plant tooth grinding gathered is bored.
The purpose of this utility model can be realized by following technical proposal：
The grinding of one tooth-implanting is bored, including in shaft-like shank body and the work department positioned at shank body end, it is characterised in that it is described
Work department is in spherical shape, and above-mentioned work department sidepiece has the recessed groove of some spiral shapes, formed between above-mentioned adjacent two groove
For the edge of a knife of machining, above-mentioned shank body rear end is used to be connected with actuator, and above-mentioned front end of the shank body has the mistake seamlessly transitted
Cross portion and above-mentioned work department is connected with transition part.
At the gum for the insertion patient that can substantially stablize in the work department of spherical shape, certainly, needed in process of lapping
Abrasive grain corresponding to configuration.Because the shank body that grinding is bored is connected with actuator, therefore, actuator drives grinding to bore rotation process
In, the grinding operation that can be stablized by the edge of a knife at work department.
Can be discharged by chip thing along groove in process of lapping, meanwhile, it is avoided that shank body hinders in the presence of transition part
Block state by chip thing and abrasive grain.
The setting of transition part can make work department external diameter be more than shank body size as far as possible, be effectively increased milling area.
In above-mentioned plant tooth grinding is bored, the shank body and work department are integral type structure.
In above-mentioned plant tooth grinding is bored, the transition part is in the small outer radius of circular cone shape and transition part and above-mentioned work
Portion is connected.
Such structure avoids by shank body being stopped by chip thing and abrasive grain.
In above-mentioned plant tooth grinding is bored, the quantity of the groove is six, has six edges of a knife at above-mentioned work department.
In above-mentioned plant tooth grinding is bored, the work department external diameter is slightly larger than shank body external diameter.
In above-mentioned plant tooth grinding is bored, the work department external diameter is 1.2-1.6 times of shank body external diameter.
In above-mentioned plant tooth grinding is bored, the inclined circular arc of the edge of a knife.
In above-mentioned plant tooth grinding is bored, there is recessed connecting seat, above-mentioned front end of the shank body is with being connected at the work department
Seat matches and front end of the shank body tight fit connection is at above-mentioned connecting seat.
The grinding of split-type structural, which is bored, to be easy to fabricate.
In above-mentioned plant tooth grinding is bored, the work department is fixedly connected with shank body by glue.
In above-mentioned plant tooth grinding is bored, the work department is fixedly connected with shank body by welding.
Compared with prior art, the grinding of this plant tooth is bored because work department is in being in substantially spherical shape, and therefore, it can be to inside and outside
The grinding operation that the face of cylinder, circular conical surface, convex spherical and concave spherical surface can be stablized, its stability are higher.
Meanwhile the setting of transition part can make, by the stable discharge of chip thing and abrasive grain, to be not in jam phenomenon, enter
One step improves its stability.
Brief description of the drawings
Fig. 1 is the structural representation that the grinding of this plant tooth is bored.
In figure, 1, shank body；1a, transition part；2nd, work department；2a, groove；2b, the edge of a knife.
Embodiment
As shown in figure 1, planting tooth grinding and boring includes being in shaft-like shank body 1 and the work department 2 positioned at the end of shank body 1, the work
It is in spherical shape to make portion 2, and the above-mentioned sidepiece of work department 2 has between some spiral shapes recessed groove 2a, above-mentioned adjacent two grooves 2a
The edge of a knife 2b for machining is formed, the above-mentioned rear end of shank body 1 is used to be connected with actuator, and the above-mentioned front end of shank body 1 has smooth
The transition part 1a of transition and above-mentioned work department 2 is connected with transition part 1a.
The shank body 1 and work department 2 are integral type structure.
The transition part 1a is connected in circular cone shape and transition part 1a small outer radius with above-mentioned work department 2.
The quantity of the groove 2a is six, has six edge of a knife 2b at above-mentioned work department 2.
The external diameter of work department 2 is slightly larger than the external diameter of shank body 1.
The external diameter of work department 2 is 1.2-1.6 times of the external diameter of shank body 1.
The circular arc inclined edge of a knife 2b.
There is recessed connecting seat, above-mentioned front end of the shank body matches with connecting seat and front end of the shank body is tight at the work department 2
It is connected at above-mentioned connecting seat.
