Technical field
The utility model relates to a kind of lens device of turning back, especially a kind of lens device of turning back of high-power carbon dioxide laser.
Background technology
The lens device of turning back that existing carbon dioxide laser uses all is the combination of microscope base and the eyeglass of turning back of turning back, it all is the traditional eyeglass loading pattern of utilization, in long-term use, expose some problems: because the existing mirror microscope base of turning back is pack into successively heat conduction spring and eyeglass on two concave station rank, promptly on the recessed ledge frame plane of mirror microscope base of turning back, put into the heat conduction spring, and guarantee the plane height of the height of heat conduction spring under situation about not stressing than fovea superior step, the plane of aspect ratio recessed ledge frame that will guarantee the heat conduction spring after reinforcing is low, the reason of Yao Qiuing is that the heat that assurance heat conduction spring can distribute the eyeglass of turning back is reliably taken away like this, so require the heat conduction spring to contact reliably with the eyeglass of turning back, for heat conductivity is preferably arranged, the existing mirror microscope base of turning back is generally processed by copper.When producing assembling, the staff will select qualified product from the heat conduction spring, just can reach above-mentioned requirements, but because the concave station rank difficulty of processing of copper is big, this with regard to causing because the own dimensional accuracy problem of microscope base and can not be up to standard, can only allow anti-worker again, make production cost improve, reduce production efficiency; Easily cause man-hour the step circumferential surface that Zou Wen is arranged owing to the concave station rank add simultaneously, thereby make the plane on concave station rank and heat conduction spring not to be adjacent to fully, that presses sometimes is tight slightly, and eyeglass meeting temperature distortion causes laser power to descend.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of processing that is easy to is provided, and is simple in structure, and perfect heat-dissipating, the device thereby the novel carbon dioxide laser that can reduce the laser failure rate is turned back.
Technical scheme: a kind of laser device of turning back, comprise microscope base body, gland, gland and the mirror of turning back, have to establish along the interior circle of central through hole on the end face of microscope base body of central through hole and be provided with ring-shaped step; The cylindrical of an end face upper edge central through hole that has the gland of central through hole is provided with and the suitable projection of the ring-shaped step of microscope base body, the projection of gland is installed in the ring-shaped step of microscope base body, and the interior circle of upper edge, the other end central through hole of gland is provided with annular groove; The center is that an end face of the gland of through hole is provided with the annular boss adaptive with the annular groove of gland along the cylindrical of central through hole, and the annular boss of gland is installed in the annular groove of gland; One end face of the described mirror of turning back is provided with water inlet pipe mouth and the effluent pipe mouth that is communicated with the interior cooling water channel of mirror body of turning back, and the mirror of turning back is installed in the central through hole of microscope base body, gland and gland.
Preferably, the microscope base body is provided with the annular groove that is used to install sealing gasket towards an end face of resonant cavity cavity along the cylindrical of central through hole, can make sealing property better after installing like this.
Preferably, be provided with sealing gasket between microscope base body and the gland, effectively strengthen sealing.
Preferably, bolt connects between microscope base body and the gland, and bolt can be dismantled easily, install.
Preferably, be to be threaded between gland and the gland, can prevent from when installing, to skid at gland outer setting material.
Beneficial effect: the turn back microscope base of device of (1) carbon dioxide laser of the present utility model changes aluminum into, and mirror-seat structure is simple, is easy to processing, adopt a dark step that the mirror of turning back directly is installed, because architecture advances, after the processing, do not had defective item, saved production cost greatly.(2) the utility model does not re-use the heat conduction spring, but with the mirror of turning back that carries cooling system, radiating effect is better, thereby has reduced the laser failure rate.
