Abstract
The utility model discloses a lens double-protection optical fiber laser cutting head which comprises a light beam channel body, a focusing lens, an upper protection mirror and a lower protection mirror. A vertical through hole for light beam to pass through is arranged in the light beam channel body, at least one upper protection mirror, the focusing lens and at least one lower protection mirror are respectively and detachably embedded in the light beam channel body and respectively cover the longitudinal section of the vertical through hole, and the upper protection mirror and the lower protection mirror are respectively arranged on two axial sides of the focusing lens. The upper protection mirror can block scrap and grease pollution of a movable part in an upper portion light path, the lower protection mirror can prevent slag and steam from spraying, the focusing lens is effectively protected from being polluted and damaged. When the surfaces of the upper protection mirror and the lower protection mirror are damaged, a new upper protection mirror and a new lower protection mirror can be replaced. Due to the fact that the prices of the upper protection mirror and the lower protection mirror are lower than the focusing lens, the service life of the focusing lens is prolonged effectively, and using and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of laser weld and cutting equipment, particularly a kind of lens double protection optical laser cutting head.
Background technology
Condenser lens is the important optics of laser process equipment, and effect is that the laser beam that laser instrument is exported is converged in a bit, and laser energy is concentrated, thereby realizes the processing such as cutting, welding, heat treatment.Condenser lens adopts special material, special process to be made, and is expensive.Should keep the cleaning of condenser lens in the use procedure, avoid the foreign substance pollutions such as dust.In the actual condition, the movement parts chip drops, carries grease in the assist gas in the splash of slag and metallic vapour, the light path, unavoidably, lens can only use several days just contaminated and damage, this has increased the operation and maintenance cost of laser process equipment, reduce operating efficiency, affected the promotion and application of laser process equipment.
The utility model content
In order to overcome defects, the utility model provides a kind of lens double protection optical laser cutting head, and this lens double protection optical laser cutting head has effectively prolonged the service life of condenser lens, reduces the operation and maintenance cost.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of lens double protection optical laser cutting head, comprise for the beam channel body of transmission laser beam with for the condenser lens that described laser beam is converged, also comprise protective glasses and lower protective glasses, be provided with a vertical through hole that supplies light beam to pass through in the described beam channel, described protective glasses at least one, condenser lens and at least one lower protective glasses can be dismantled respectively sealing and be embedded in the beam channel, and the vertical through hole that covers respectively beam channel is section radially, and described upper protective glasses and lower protective glasses lay respectively at the axial both sides of condenser lens.
As further improvement of the utility model, described upper protective glasses, condenser lens and lower protective glasses can be dismantled the structure that sealing is embedded in the beam channel: be provided with first, two, three microscope bases and first, two, three end caps, upper protective glasses, condenser lens and lower protective glasses fixedly are embedded at first respectively, two, in the endoporus on three microscope bases, be provided with in the described beam channel body with vertical through hole intersect vertically first, two, three microscope base chambeies, first, two, three microscope bases seal respectively and are inserted in first, two, in the three microscope base chambeies, first, two, three end caps are fixed in first by lock screw respectively, two, the opening part in three microscope base chambeies.
As further improvement of the utility model, described first, second and third microscope base both ends of the surface vertically are positioned in first, second and third microscope base chamber by the sealing ring sealing respectively.
As further improvement of the utility model, described upper protective glasses and lower protective glasses are the plane light-transmission mirror.
The beneficial effects of the utility model are: the utility model arranges in the axial both sides of condenser lens; lower protective glasses; upper protective glasses stops the pollution of chip and the grease of movement parts in its upper optical path; lower protective glasses stops from slag and steam splash; effectively protected condenser lens not contaminated and the damage; after upper protective glasses and lower protective glasses damaged surfaces; the upper protective glasses that replaceable installation is new and lower protective glasses; because upper; the price of lower protective glasses is well below condenser lens; so such mechanism has effectively prolonged the service life of condenser lens, reduce the operation and maintenance cost.
