Abstract
The utility model relates to an airflow protector for laser focusing lens, and is characterized in that a lens fixture (3) is provided inside with a cone-shaped cavity (1), the cone surface of the cone-shaped cavity (1) is directly connected with an air inlet of an high pressure air resource through a through-hole (4) on the lens fixture (3), an air outlet of the high pressure air resource is coaxial with a cone top through-hole (5); the utility model can isolate a lens with a dust in operation, and can avoid the decreasing of laser transmittance resulting from the dust suction in a workpiece treatment process, and can overcome the problem that non-metal material causes a combustion under the illumination of laser, and functions as the cooling of the lens at the same time; the airflow protector for laser focusing lens made according to the utility model can bring up an positive using effect in the industries of laser, sculpture, cutting and plate-making.
Description
The utility model relates to a kind of improvement invention of laser focusing camera lens, particularly be the invention of the protective device of laser focusing camera lens, what be specifically related to is the invention of the air-flow protection device of laser focusing camera lens.
In the prior art, the cutting of nonmetal laser engraving, a kind of mode adopts material surface to spray cooling water, and the protection working face operate loaded down with trivial detailsly, and efficient is low, and requires the employing long-focus lens, and the luminous energy loss is big; Another kind of mode adopts the air-flow protection device; working method is that its light path and gas circuit are not on same axis; though this air-flow protection device has solved nonmetallic materials and easily produced the problem of burning under laser radiation; but easily make flue dust adhere to laser focusing eyeglass surface, reduce the transmitance of laser.
Problem in view of the known technology existence; it is coaxial that the purpose of this utility model aims to provide a kind of phosgene road; both solved the problem that nonmetallic materials are burnt under laser radiation; can protect the focusing lens surface not by flue dust adhesion, cooling laser focusing lens again; simultaneously can play the raising depth of cut, make the air-flow protection device of the laser focusing camera lens that the surface of the work joint-cutting is little, tangent plane is smooth.
The utility model is finished as follows: the air-flow protection device of this laser focusing camera lens; it is characterized in that in the camera lens fixed body, being provided with conical cavity; and be provided with through hole at the vertex of a cone of conical cavity; be provided with through hole by the camera lens fixed body on the taper seat of described conical cavity; this through hole directly is connected with the air inlet of high-pressure air source; the outlet of described high-pressure air source and vertex of a cone through hole (5) are on same axis, and the drift angle of described conical cavity is 30-80 °.
Compared with prior art; the utlity model has scientific and reasonable for structure; overcome nonmetallic materials and under laser radiation, produced the problem of burning; and can protect on the focusing lens and do not adhered to by flue dust; and can cool off advantages such as focusing lens fast, and remove the flue dust on processing work surface simultaneously, improved depth of cut; according to the air-flow protection device of the laser focusing camera lens of the utility model design motif made, will bring positive result of use in laser engraving cutting industry.
The utility model has following accompanying drawing:
Fig. 1 is a structural scheme of mechanism of the present utility model;
Fig. 2 is the utility model figure vertical view.
Accompanying drawing has been represented structure of the present utility model and embodiment, further describes the relevant details of embodiment below more in conjunction with the accompanying drawings.The air-flow protection device of this laser focusing camera lens is provided with conical cavity 1 in camera lens fixed body 3; this air-flow protection device is fixed on the laser focusing lens barrel with the groove on the camera lens fixed body 32; the top of described conical cavity 1 is the space that produces cyclone when high pressure draught is entered; reach the effect of protection focusing lens (not shown); cooled off the temperature of focusing lens effectively; the vertex of a cone at conical cavity 1 is provided with through hole 5; this through hole 5 both can have been done the gases at high pressure outlet; the combustion problem that nonmetallic materials are produced under laser radiation is controlled effectively; can make laser see through this through hole again carves or cuts; be provided with through hole 4 by the camera lens fixed body on the taper seat of described conical cavity 1; this through hole 4 directly is connected with the air inlet of high-pressure air source; described light path and gas circuit are coaxial at the port of export; the drift angle of described conical cavity is 30-80 °; present embodiment adopts 50 °; when the nonmetallic materials of engraving cutting are burnt easily; its high-pressure air source can adopt inert gas, cut point is cooled off fast and formation certain protection space on every side.
