Abstract
The invention discloses a water-oil filtering side blowing nozzle for a laser head. The water-oil filtering side blowing nozzle is formed by connecting a side blowing nozzle outer layer with a side blowing nozzle inner layer which are each provided with a coaxial outlet. The outlet of the side blowing nozzle inner layer is used for allowing laser light to pass through, and the outlet of the side blowing nozzle outer layer is used for allowing the laser light and side blowing airflow to pass through. An annular cavity is formed between the side blowing nozzle inner layer and the side blowing nozzle outer layer to allow the side blowing airflow to pass through. The side blowing nozzle inner layer, the laser head and a condensing lens jointly form a condensing lens inner chamber, the side blowing airflow directly flows out from the outlet of the side blowing nozzle outer layer instead of entering the condensing lens inner chamber under the action of the negative pressure effect of the outlet of the side blowing nozzle outer layer, and accordingly the condensing leans is protected from being polluted.
Description
Technical field
The present invention relates to laser cutting, engraving field, specifically refer to that laser head water, oil filter side blowing nozzle.
Background technology
Current known laser head side blowing nozzle is: side blowing nozzle is made up of individual layer, and middle ringless-type interlayer, lateral gas flow directly flows out from side blowing nozzle bright dipping mouth after side blowing nozzle inner chamber. The shortcoming of this product is: owing to side-blown gas is normal air pressurized gas, containing water vapour and oil vapour in gas, they are gathered on condensing lens can be condensed into drop through side blowing nozzle inner chamber, like this will severe contamination condensing lens, greatly reduce its transmittance, cause laser equipment cannot non-stop run, also shorten the life-span of condensing lens simultaneously.
Summary of the invention
For overcoming the defect that above-mentioned prior art exists, the present invention provides a kind of laser head water, oil to filter side blowing nozzle, water in laser head side-blown gas, fluid body or steam can be separated from laser head and discharge laser head by this laser head water, oil filtration side blowing nozzle, avoids the lens in laser head to pollute by it and damage.
The present invention solves the problems of the technologies described above the technical scheme adopted: laser head water, oil filters side blowing nozzle and is formed by connecting with side blowing nozzle internal layer by side blowing nozzle is outer, side blowing nozzle is outer all has an axis outlet with internal layer, internal layer outlet is passed through for laser, outer outlet is passed through for laser and lateral gas flow, two layers of intermediate formation annular cavity passes through for lateral gas flow, side blowing nozzle internal layer and laser head and condensing lens form a condensing lens inner cavity chamber jointly, lateral gas flow is under the effect of the underbalance effect of side blowing nozzle skin outlet, condensing lens inner cavity chamber can not be entered, but directly flow out from side blowing nozzle skin outlet, thus protect condensing lens from pollution.
The useful effect of the present invention is: side-blown gas imports after the circular cone annular cavity that mouth importing is made up of side blowing nozzle skin and internal layer through side-blown gas; outflow is exported outside side blowing nozzle; due to the underbalance effect of air-flow; such side-blown gas can not flow into lens inner cavity chamber; then water, oil vapour flow out from side-blown gas outlet with air-flow; condense upon on a small quantity on circular cone annular cavity wall, and can not flow in the inner chamber at lens place, thus protect condensing lens from pollution.

Embodiment
Shown in Fig. 1 Fig. 4, laser head water of the present invention, oil filter side blowing nozzle and are formed by connecting by side blowing nozzle skin (1) and side blowing nozzle internal layer (2), the profile of side blowing nozzle skin (1) and side blowing nozzle internal layer (2) is all cylindrical in upper part and bottom is divided into cone, the inner side of side blowing nozzle skin (1) and side blowing nozzle internal layer (2) is all cylindrical in upper part and bottom is divided into conical cavity, and they form a middle circle conical ring cavity after connecting, side blowing nozzle and laser head and condensing lens define a condensing lens inner chamber being made up of the outlet of laser head (8), laser focusing lens (9) and side blowing nozzle internal layer (2) after connecting, side blowing nozzle skin (1) is provided with side-blown gas entrance (3) and side-blown gas and laser beam and exports (5), and side blowing nozzle internal layer (2) is provided with laser beam outlet (4), long-pending liquid derives ring groove (6) and long-pending liquid export mouth (7), after side blowing nozzle and laser head and condensing lens connection, side-blown gas imports after middle circle conical ring cavity through side-blown gas entrance (3), flow out through side-blown gas and laser beam outlet (5), due to the underbalance effect of lateral gas flow, water in side-blown gas, oil vapour flows out through side-blown gas and laser beam outlet (5) with side-blown gas, a small amount of water, oil vapour remnants can condense upon and form water in circular cone annular cavity, fluid body, flow out through side-blown gas and laser beam outlet (5) with side-blown gas when laser head bright dipping mouth down, or laser head bright dipping mouth upward time rely on the gravity of self to flow into long-pending liquid after middle circle conical ring cavity to derive ring groove (6), derive through long-pending liquid export mouth (7) again.
Laser head down time, water, oil vapour and liquid all flow out through side-blown gas and laser beam outlet (5) with lateral gas flow, so in kind situation, side blowing nozzle internal layer (2) can not arrange long-pending liquid derivation ring groove (6) and long-pending liquid export mouth (7).
In the technical program; side blowing nozzle and laser head and condensing lens define a condensing lens inner chamber being made up of the outlet of laser head (8), laser focusing lens (9) and side blowing nozzle internal layer (2) after connecting; like this; due to the underbalance effect of air-flow; after side-blown gas flows through intermediate annular cavity; deriving through side-blown gas and laser beam outlet (5) and can not flow into condensing lens inner chamber, condensing lens is protected.
