Abstract
The utility model discloses a beam expander for a disc cutting machine. The beam expander comprises a lens barrel, an input lens and an output lens, the input lens is fixed at an input end of the lens barrel, and the output lens is adjustably mounted at an output end of the lens barrel. By the aid of the beam expander for the disc cutting machine, an optical adjusting frame is omitted, components of the cutting machine are decreased, debugging requirements of the beam expander are lowered, factors affecting beam expanding effects are decreased, and the beam expander is simpler and more convenient to operate.
Description
Technical field
The utility model relates to a kind of beam expanding lens, relates in particular to a kind of beam expanding lens for video disc cutting machine.
Background technology
The input mirror of conventional laser beam expanding lens and outgoing mirror be fixed on lens barrel nonadjustable, its using method is that whole lens barrel is placed on optical adjusting frame, by regulating optical adjusting frame to regulate angle and the position of beam expanding lens, expectation obtains the good laser beam of collimation through expanding.But because such beam expanding lens must be equipped with the optical adjusting frame of coupling, the precision of adjustment rack, stability can have a strong impact on and expand effect, and the profile of beam expanding lens is divided into again straight tube and two kinds of different forms of cone, diameter is also not quite similar, make the outfit of its adjustment rack have certain difficulty, applicability is lower.In addition, beam expanding lens is placed on optical adjusting frame and is also not easy to fix, it is unfavorable to the good laser beam of its stable output collimation, to have caused.
Utility model content
The purpose of this utility model is to provide a kind of beam expanding lens for video disc cutting machine, without being equipped with optical adjusting frame, has reduced the parts of cutting machine, has reduced equipment debugging demand, has reduced and has affected the factor that expands effect, easy and simple to handle.
For achieving the above object, the utility model provides a kind of beam expanding lens for video disc cutting machine, comprise lens barrel, input mirror and outgoing mirror, described input mirror is fixed on the input of described lens barrel, the output that is arranged on described lens barrel of described outgoing mirror position-adjustable.
Preferably, the output of described lens barrel is provided with for regulating the set screw of described outgoing mirror position, and described set screw connects described outgoing mirror.
Preferably, described set screw has four, and four described set screw are connected respectively upper and lower, left and right four sides of described outgoing mirror.
Preferably, the input of described lens barrel is arranged with fixed part outward, and described fixed part is fixedly connected with a cutting machine laser head by holding screw.
Preferably, on described fixed part, offer screwed hole, described holding screw is arranged on described screwed hole place.
Preferably, described screwed hole has four, and four described screwed holes are equally distributed on described fixed part, described in each screwed hole place be provided with one described in holding screw.
Compared with prior art, beam expanding lens for video disc cutting machine of the present utility model is by the adjustable outgoing mirror of output setting position at described lens barrel, can make the focus of described outgoing mirror aim at laser beam, just can obtain the good laser beam of collimation through expanding, without being equipped with optical adjusting frame, not only reduced the parts of cutting machine, reduced equipment debugging demand, reduced impact and expanded the factor of effect, and operated more easy; In addition, due to can described lens barrel is whole fixing by holding screw, therefore make beam expanding lens stability better, be more conducive to it and obtain the good laser beam of collimation through expanding, guarantee the Output of laser quality of video disc cutting machine, thereby improve the precision of equipment.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of beam expanding lens.
Fig. 2 is the front view of beam expanding lens output.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-2, the described beam expanding lens for video disc cutting machine comprises lens barrel 1, input mirror 2 and outgoing mirror 3.
Described input mirror 2 is fixed on the input 11 of described lens barrel 1.The outer fixed part 12 that is arranged with of input 11 of described lens barrel 1, on described fixed part 12, offer four screwed holes 121, four described screwed holes 121 are equally distributed on described fixed part 12, described in each, screwed hole 121 places are provided with a holding screw (not shown), described fixed part 12 is fixedly connected with cutting machine laser head (not shown) by four described holding screws, thereby can guarantee that video disc cutting machine laser instrument output and beam expanding lens keep axiality.
The output that is arranged on described lens barrel 1 13 of described outgoing mirror 3 position-adjustable.The output 13 of described lens barrel 1 is provided with for regulating the set screw 4 of described outgoing mirror 3 positions, and described set screw 4 connects described outgoing mirror 3.Described set screw 4 has four, and four described set screw 4 are connected respectively upper and lower, left and right four sides of described outgoing mirror 3, thereby can carry out position adjustments up and down to described outgoing mirror 3.
When the beam expanding lens for video disc cutting machine is carried out to laser bundle-enlarging collimation, without being equipped with optical adjusting frame, only need described input 11 is fixing, and the position of described outgoing mirror 3 is regulated, so that the focus of described outgoing mirror 3 is aimed at laser beam, just can obtain the good laser beam of collimation through expanding, not only operation is more easy, and reduced the parts of cutting machine, and reduced equipment debugging demand, reduced the factor that impact expands effect; In addition, due to can described lens barrel 1 is whole fixing by holding screw, therefore make beam expanding lens stability better, be more conducive to it and obtain the good laser beam of collimation through expanding, guarantee the Output of laser quality of video disc cutting machine, thereby improve the precision of equipment.
Above combination most preferred embodiment is described the utility model, but the utility model is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
