Description
Technical field
This utility model relates to a kind of diamond tool, and it relates to a kind of diamond thin-wall drill bit in particular.
Background technology
At present, in prior art, Authorization Notice No. is that the Chinese patent document of CN202911007U discloses a kind of diamond thin-wall drill bit, and including thin drilling bit matrix, the front end of thin drilling bit matrix is provided with working lining.
Diamond thin-wall drill bit is mainly used on the hard article such as pottery, glass punching, in order to improve the perforating efficiency of drill bit and improve the service life of drill bit, need when drill bit punches to drill bit spraying cooling water, but when punching deeper, owing to thin drilling bit is the least with the hole wall gap of object to be processed, even if this gap is filled up by cooling water, the content of its cooling water is the most less, and the cooling water on top does not act on the operating position of drill bit, do not play effective cooling effect.
Summary reason, traditional above-mentioned drill bit is when spraying cooling water, and the actual cooling effect produced is unsatisfactory.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of when filling coolant, the more preferable diamond thin-wall drill bit of cooling effect.
For achieving the above object, this utility model provides following technical scheme: a kind of diamond thin-wall drill bit, including cylindrical body, the front end inside and outside wall of described cylindrical body is equipped with diamond lap layer, the front end composition of diamond lap layer cladding cylindrical body is for the grinding head of boring, and the joining place of described cylindrical body and grinding head is provided with the catch basin of annular.
By using technique scheme, this utility model is provided with annular catch basin at the joining place of cylindrical body Yu grinding head, during persistently filling coolant, coolant can converge in catch basin, and catch basin is very close to grinding head, during grinding head continuous firing, converge at the coolant of catch basin can constantly penetrate into the work surface of grinding head it is cooled down, and cooling liquid measure in catch basin is the most, when part penetrates into the work surface of grinding head, the coolant at rear can be continuously replenished, can play avoid grinding head pierce the degree of depth increase time, the effect that coolant cannot be supplemented in time.And by arranging the structure of catch basin, it is possible to the amount of the coolant acting on grinding head also has increase largely.By above scheme, thus to this drill bit during filling coolant, particularly grinding head part plays more preferable cooling effect so that it is be difficult to overheating deforming, improves the service life of this drill bit.
This utility model is further arranged to: the end of described grinding head axially offers and extends to catch basin and the water inlet breach of the through grinding head of radial direction.
By using technique scheme, water inlet breach radially through grinding head, and water inlet breach extends in catch basin, the coolant in catch basin can directly penetrate into the inwall of grinding head through water inlet breach, the inwall of grinding head is cooled down, further increases cooling effect.
This utility model is further arranged to: described cylindrical body sidewall offers water filling port.
By using technique scheme, water filling port can be used for the filling coolant of the inwall to cylindrical body so that coolant penetrates into grinding head along the inwall of cylindrical body, all cools down grinding head and cylindrical body, improves cooling effect.
This utility model is further arranged to: the inwall of described cylindrical body axially offers the groove extending to grinding head.
By using technique scheme, the groove of setting can increase coolant in the passage gaps of cylindrical body inwall, is more conducive to coolant and oozes to grinding head so that cooling effect is more preferable.
Preferably, the thickness of described diamond lap layer is 0.5-1.5mm.
Preferably, the quantity of described water inlet breach is multiple, and is uniformly arranged along grinding head circumference.
Preferably, the quantity of described groove is a plurality of, is uniformly arranged along cylindrical body circumference.
In sum, this utility model provides a kind of when filling coolant, and the more preferable diamond thin-wall drill bit of cooling effect, service life is longer.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment one, as shown in Figure 1-2, a kind of diamond thin-wall drill bit, including cylindrical body 1, the front end inside and outside wall of cylindrical body 1 is equipped with diamond lap layer 3, and the thickness of diamond lap layer 3 is 0.5-1.5mm；Diamond lap layer 3 is coated with the front end of cylindrical body 1 and constitutes the grinding head 2 for boring, and cylindrical body 1 is provided with annular catch basin 4 with the joining place of grinding head 2.
Axially offering in the end of grinding head 2 and extend to catch basin 4 and the water inlet breach 5 of the through grinding head 2 of radial direction, the quantity of water inlet breach 5 is two, and is uniformly arranged along grinding head 2 circumference；And cylindrical body 1 sidewall offers water filling port 6.
Good effect of the present utility model is, joining place at cylindrical body 1 with grinding head 2 is provided with the catch basin 4 of annular, during persistently filling coolant, coolant can converge in catch basin 4, and catch basin 4 is very close to grinding head 2, during grinding head 2 continuous firing, converge at the coolant of catch basin 4 can constantly penetrate into the work surface of grinding head 2 it is cooled down, and cooling liquid measure in catch basin 4 is the most, when part penetrates into the work surface of grinding head 2, the coolant at rear can be continuously replenished, can play avoid grinding head 2 pierce the degree of depth increase time, the effect that coolant cannot be supplemented in time.And by arranging the structure of catch basin 4, it is possible to the amount of the coolant acting on grinding head 2 also has increase largely.By above scheme, thus to this drill bit during filling coolant, particularly grinding head 2 part plays more preferable cooling effect so that it is be difficult to overheating deforming, improves the service life of this drill bit.
Additionally, water inlet breach 5 radially through grinding head 2, and water inlet breach 5 extends in catch basin 4, coolant in catch basin 4 can directly penetrate into the inwall of grinding head 2 through water inlet breach 5, cooling down the inwall of grinding head 2, water filling port 6 can be used for the filling coolant of the inwall to cylindrical body 1 so that coolant penetrates into grinding head 2 along the inwall of cylindrical body 1, grinding head 2 and cylindrical body 1 are all cooled down, thus further improves cooling effect.
Embodiment two, as shown in Figure 3-4, the difference with embodiment one is, the inwall of cylindrical body 1 axially offers the groove 7 extending to grinding head 2, and the quantity of groove 7 is four, is uniformly arranged along cylindrical body 1 circumference.The groove 7 arranged can increase coolant in the passage gaps of cylindrical body 1 inwall, is more conducive to coolant and oozes to grinding head 2 so that cooling effect is more preferable.
In sum, this utility model provides a kind of when filling coolant, and the more preferable diamond thin-wall drill bit of cooling effect, service life is longer.
These are only preferred embodiment of the present utility model, be not limited to this utility model, all within design concept of the present utility model, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
