Description
Technical field
The utility model relates to a kind of automatic water jetting drill bit.
Background technology
Current drill bit is not owing to having water injector, and the airborne dust brought when needing artificial water spray to avoid electric drill to punch and the hot problem of drill bit, not only greatly reduce operating efficiency but also reduce service life of drill bit.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of above prior art: provide a kind of automatic water jetting drill bit.
Technical solution of the present utility model is as follows: a kind of automatic water jetting drill bit, comprises drill body; The top of described drill body is provided with hole for water spraying; The sidewall of described drill body bottom is provided with the centrifugal compressed water generation apparatus that symmetry is fixed on bit-body axis both sides; Be provided with the column water cavity of a transverse direction in described centrifugal compressed water generation apparatus, the inner side of described column water cavity is provided with the piston by being located at the extension spring connection on its inner face; The inner sidewall of described column water cavity is provided with air-vent, and outer end sidewall is provided with water filling port and delivery port; Described water filling port is provided with sealing-plug; Described delivery port and hole for water spraying are by the pipeline communication in drill body.
Air-vent is communicated with air by the through hole of drill body bottom sidewall.
Described piston is the circular iron block that perisporium is provided with rubber ring.Piston inertia can be increased.
The beneficial effects of the utility model are: the utility model is operationally due to the effect of centrifugal force, piston can to the outer end motion of column water cavity, thus the water in column water cavity is pressed into the intrinsic pipeline of drill bit by delivery port and from the hole for water spraying ejection the end face of drill body top, realizes the automatic water jetting of drill bit; When drill bit stops operating, extension spring is by piston reset, can carry out the action of second time setting-out; Water in column water cavity can be injected by water filling port and be sealed by sealing-plug.

Detailed description of the invention
With specific embodiment, the utility model is described in further details below, but the utility model is not only confined to following specific embodiment.
Embodiment
As shown in Figure 1-2, a kind of automatic water jetting drill bit, comprises drill body; The top end face of described drill body is provided with hole for water spraying 1; The sidewall of described drill body bottom is provided with the centrifugal compressed water generation apparatus that symmetry is fixed on bit-body axis both sides; Be provided with the column water cavity 2 of a transverse direction in described centrifugal compressed water generation apparatus, the inner side of described column water cavity 2 is provided with the piston 3 by being located at the extension spring connection on its inner face; The inner sidewall of described column water cavity 2 is provided with air-vent 4, and outer end sidewall is provided with water filling port 5 and delivery port 6; Described water filling port 5 is provided with sealing-plug; Described delivery port 6 and hole for water spraying 1 are by the pipeline communication in drill body.
Air-vent 4 is communicated with air by the through hole of drill body bottom sidewall.
Described piston 3 is provided with the circular iron block of rubber ring for perisporium.
Below be only that feature of the present utility model implements example, the utility model protection domain is not constituted any limitation.The technical scheme that all employings exchange on an equal basis or equivalence is replaced and formed, all drops within the utility model rights protection scope.
