Description
Technical field
The present invention relates to a kind of spray heads, and in particular to a kind of self-rotation spray head.
Background technique
After the production and processing of the tube-like pieces such as casing, metal fillings remaining on casing inner surface need to be purged by spray head,
Usually metal fillings is blown away by high pressure gas, to improve production efficiency, worker mostly uses plurality of nozzle-type spray head.Plurality of nozzle-type
Spray head has the inclined nozzle of several opposing showerheads, if so that spray head sprays carried interest air-flow, but ejection air-flow institute to circumferential front side
The air curtain of formation is simultaneously uneven, there are gap or in the presence of interference between the air-flow between adjacent nozzle；To solve this problem, worker will
Spray head and automatic jig cooperate so that spray head energy rotation, but the connection kind of drive between existing tooling and spray head is sufficiently complex.
Summary of the invention
The object of the present invention is to provide a kind of low costs, revolvable self-rotation spray head.
To achieve the above object, the present invention adopts the following technical scheme: a kind of self-rotation spray head, it is characterised in that including
Fixing seat and spray head, the fixing seat include fixed part and pipe portion, and main through slot is formed in the fixing seat, is formed in fixing seat
There are main through slot import and the outlet of main through slot, main through slot import is set on fixed part, and main through slot outlet is set to pipe portion axial end
On face, the spray head structure setting cylindrical in shape is with spray head slot, if the spray head is rotatably fixed on pipe portion by dry bearing
Sealing block in a ring, sealing block are combined between the spray head slot circumferential direction cell wall of outer circumferential, the pipe portion peripheral outer wall and spray head
Spray head slot is divided into preceding spray head slot and rear spray head slot, the spray head front end is equipped with several nozzles being connected with preceding spray head slot,
The spray head is formed with through slot several times, described secondary through slot one end be formed on the circumferential cell wall of preceding spray head slot time through slot into
Mouthful, the secondary through slot other end is formed with time through slot outlet after the spray head is corresponding in the peripheral outer wall at the position of spray head slot,
The secondary through slot outlet axes and spray head peripheral outer wall outer rim are tangent, when secondary through slot at least two, the secondary through slot outlet
Uniform intervals are set on the spray head in a ring.
When the fixing seat air inlet of spray head or feed liquor, gas or liquid pass sequentially through main channel, preceding spray head slot and nozzle with
The ejection for carrying out high pressure gas or liquid, since spray head of the invention is equipped with through slot several times, and the secondary through slot of secondary through slot goes out
Mouth axis and spray head axis outer wall are tangent, and the air-flow or liquid that secondary through slot outlet sprays will drive spray head and rotate relative to pipe portion, with
Realize the rotation of spray head.Spray head of the present invention can be directly anchored in tooling, without linking between tooling and spray head
The setting of mechanism, the cleaning being more convenient for tube-like piece inner wall；Wherein, be set as needed fixing seat shape and and size, with
It is connected and fixed convenient for the present invention with tooling.Wherein, sealing block is used to avoid the waste of high pressure gas or liquid, to reduce air pump
