The utility model aims to provide a kind of plug, to solve the technical problem that processing cost is high, working (machining) efficiency is low, security is low that existing plug exists.
For achieving the above object, the utility model provides a kind of plug, for carrying out shutoff to the hole on workpiece to be sprayed, plug comprises: plug body, plug body comprises to carry out the closure part of shutoff to it in patchhole, and be connected with closure part and appearance and size be greater than the diameter in hole expose portion; Expose for bearing the conical surface of spraying power when portion being processed with spraying, the middle line parallel in the hole that the rotation center line of the conical surface and plug body insert, and the flared end of the conical surface is towards closure part.
Further, the portion of exposing comprise be connected with closure part and appearance and size is greater than the backstop section of the diameter in hole and the centrum section be connected with backstop section; Centrum section is processed with the conical surface, and the center line in the hole that the rotation center line of the conical surface inserts with plug body overlaps.
Further, backstop section is circular cone shape, and its necking end is connected with closure part, and its flared end is connected with centrum section.
Further, centrum section is cone shape, and its big opening end is connected with the end face of the flared end of backstop section, and its periphery wall is the conical surface.
Further, centrum section comprises cylindrical section and conical section; One end of cylindrical section is connected with the end face of the flared end of backstop section, and the other end of cylindrical section is connected with the end face of the big opening end of conical section; The periphery wall of conical section is the conical surface.
Further, closure part is cylindrical shape, and its external diameter matches with the internal diameter in the hole for the treatment of shutoff.
The utility model has following beneficial effect:
According to plug of the present utility model, during thermal spraying, spray gun sprays the conical surface, because the conical surface of the conical surface designs, can carry out dispersed to the jet power be applied to it, thus the stability of plug in spraying can be strengthened, also make plug easily extract afterwards having sprayed;
What comprise that appearance and size is greater than the diameter in the hole of insertion due to plug body exposes portion, therefore when spray gun sprays the conical surface, the appearance and size due to the portion of exposing is greater than the diameter in hole, therefore can stop that in the whole access aperture of plug body, security is high;
In addition, the set-up time of this plug before spraying is short, and working (machining) efficiency is high;
Finally, this novel plug cost of manufacture is low and can Reusability, and processing cost is low.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, a kind of plug of the present utility model, for carrying out shutoff to the hole on workpiece to be sprayed, this plug comprises: plug body, plug body comprises to carry out the closure part 1 of shutoff to the hole of this insertion in patchhole, and is connected with closure part 1 and appearance and size is greater than the portion of exposing 2 of the diameter in hole; This exposes for bearing the conical surface 20 of spraying power when portion 2 being processed with spraying, the middle line parallel in the hole that the rotation center line of this conical surface 20 and plug body insert, and the flared end of the conical surface 20 is towards closure part 1.According to plug of the present utility model, during thermal spraying, spray gun sprays the conical surface 20, because the conical surface of the conical surface 20 designs, can carry out dispersed to the jet power be applied to it, thus the stability of plug in spraying can be strengthened, also make plug easily extract afterwards having sprayed; Because plug body comprises the portion of exposing 2 that appearance and size is greater than the diameter in the hole of insertion, therefore when spray gun sprays the conical surface 20, the appearance and size due to the portion of exposing 2 is greater than the diameter in hole, therefore can stop that in the whole access aperture of plug body, security is high; In addition, the set-up time of this plug before spraying is short, and working (machining) efficiency is high; Finally, this novel plug cost of manufacture is low and can Reusability, and processing cost is low.
Further, expose portion 2 comprise be connected with closure part 1 and appearance and size is greater than the backstop section 21 of the diameter in hole and the centrum section be connected with backstop section 21; Centrum section is processed with the conical surface 20, the rotation center line of this conical surface 20 overlaps with center line during plug body patchhole.During thermal spraying, when the center line in spray gun this hole parallel sprays hole, because the rotation center line of the conical surface 20 overlaps with center line during plug body patchhole, therefore this conical surface 20 can carry out better dispersed to the jet power be applied to it, to strengthen the stability of plug in spraying further.
Particularly, as depicted in figs. 1 and 2, backstop section 21 of the present utility model is in circular cone shape, and the necking end of the backstop section 21 of this circular cone shape is connected with closure part 1, and the flared end of the backstop section 21 of this circular cone shape is connected with centrum section.
As shown in Figure 1, the first embodiment of the present utility model, in this embodiment, centrum section is cone shape, and the big opening end of the centrum section of this cone shape is connected with the end face of the flared end of backstop section 21, and the periphery wall of the centrum section of this cone shape is the conical surface 20.
As shown in Figure 2, the second embodiment of the present utility model, in this embodiment, centrum section comprises cylindrical section 221 and conical section, and cylindrical section 221 is in cylindrical shape, and conical section is cone shape; One end of cylindrical section 221 is connected with the end face of the flared end of backstop section 21, and the other end of cylindrical section 221 is connected with the end face of the big opening end of the conical section of cone shape; The periphery wall of conical section is the conical surface 20.
As depicted in figs. 1 and 2, in the first embodiment and the second embodiment, closure part 1 is all in cylindrical shape, and the center line of the closure part 1 of this cylindrical shape overlaps with the center line in the portion of exposing 2, and the external diameter of the closure part 1 of this cylindrical shape matches with the internal diameter in the hole for the treatment of shutoff.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
According to plug of the present utility model, because the conical surface of the conical surface 20 designs, can carry out dispersed to the jet power be applied to it, thus the stability of plug in spraying can be strengthened, also make plug easily extract afterwards having sprayed; When spray gun sprays the conical surface 20, the appearance and size due to the portion of exposing 2 is greater than the diameter in hole, therefore can stop that in the whole access aperture of plug body, security is high; In addition, the set-up time of this plug before spraying is short, and working (machining) efficiency is high; Finally, this novel plug cost of manufacture is low and can Reusability, and processing cost is low.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
