Containing protective lens in the cutting head of optical-fiber laser cutting machine; to reduce the consumption of the easily-consumed products such as focus lamp; and the protective glass assembly of existing fiber laser cutting machine is arranged between protection microscope base and gland; spanner is utilized to rotate gland; protective lens is compressed, and make protective lens bear a precompression, this structure makes protective lens have crushed possibility; and by spanner, the problem of inconvenient operation, inefficiency must be there is in replacing protective lens.
Utility model content
For this reason; the purpose of this utility model is to provide a kind of for the protection of focusing lens and the protective glass assembly be convenient for changing; with solve traditional fiber laser cutting machine protective lens easily crushed, change protective lens by spanner, the problem of inconvenient operation, inefficiency must be there is.
The purpose of this utility model is achieved through the following technical solutions.
For a protective glass assembly for optical-fiber laser, comprising: protection microscope base and protective lens, described protection microscope base is provided with a circular hole clipping, two opposite sides of this circular hole clipping are respectively provided with an opening; Described protective lens is arranged in described circular hole clipping, and is also provided with an annular gland between protective lens and circular hole clipping, by annular gland matched in clearance between described protective lens and protection microscope base.
Further, be also provided with an elastic seal ring in described circular hole clipping, this elastic seal ring is positioned at immediately below protective lens, and with described protection microscope base interference fit.
Further, described protection microscope base side end is also provided with one handle, and this handle is fixed on the side end face of protection microscope base by sunk screw.
Further, a dust-proof cushion is also provided with between described handle and protection microscope base.
Further, be locked by locking stud between described handle and dust-proof cushion.
The utility model compared with prior art, beneficial effect is: the protective glass assembly for optical-fiber laser that the utility model provides, protective lens is fixed by the circular hole clipping be arranged on protection microscope base, and utilize annular gland to realize protective lens and protect the matched in clearance between microscope base, and ensure that annular gland upper surface protrudes from the upper surface of protective lens, to prevent protective lens crushed; The utility model is by being arranged on the opening of circular hole clipping two opposite end in addition, facilitate installation and the taking-up of protective lens, substantially increase installation effectiveness, make simply easier for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model protective glass assembly.
Identifier declaration in figure: protection microscope base 1, circular hole clipping 11, opening 111, protective lens 2, annular gland 3, elastic seal ring 4, handle 5, dust-proof cushion 6, locking stud 7, sunk screw 8.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
For current optical-fiber laser cutting machine, protective lens needs to rotate gland by spanner and compresses, and protective lens is easily crushed, and changes the problem that protective lens exists operation inconvenience, inefficiency.The utility model proposes a kind of for the protection of focusing lens and the protective glass assembly be convenient for changing, refer to shown in Fig. 1, Fig. 1 is the structural representation of the utility model protective glass assembly.
Protective glass assembly described in the present embodiment improves, and it includes protection microscope base 1, protective lens 2, annular gland 3, elastic seal ring 4, handle 5, dust-proof cushion 6, locking stud 7 and sunk screw 8.Wherein protect on microscope base 1 and be provided with a circular hole clipping 11, two opposite sides of this circular hole clipping 11 are respectively provided with an opening 111; Protective lens 2 is circular, and its correspondence is arranged in described circular hole clipping 11, can conveniently protective lens 2 be loaded by the opening 111 of circular hole clipping 11 liang of opposite sides and take out.
Also be provided with an elastic seal ring 4 in circular hole clipping 11, this elastic seal ring 4 is positioned at immediately below protective lens 2, and with described protection microscope base 1 interference fit, can not fall down because of deadweight.
An annular gland 3 is also provided with, by annular gland 3 matched in clearance between protective lens 2 and protection microscope base 1 between protective lens 2 and circular hole clipping 11.Annular gland 3 can be enclosed within outside protective lens 2; and after protective lens 2 is enclosed within annular gland 3 inside; the upper end face of annular gland 3 exceeds a part than the upper surface of protective lens 2, and the pressure produced to prevent upper surface directly arrives protective lens 2 surface, causes protective lens 2 impaired.
One side (side end face at non-opening 111 place) of protection microscope base 1 is also provided with a handle 5; this handle 5 is fixed on protection microscope base 1 by sunk screw 8; and a dust-proof cushion 6 is also provided with between handle 5 and protection microscope base 1, be locked by locking stud 7 between described handle 5 and dust-proof cushion 6.
Protection microscope base 1 is linked together by cross recessed countersunk head sscrew 8 with handle 5; dust-proof cushion 6 is attached to the inner side of handle 5, and locking stud 7, through the unthreaded hole at handle 5 two ends, is fixed on protective glass assembly in cutting head; dust-proof cushion 6 is compressed, enters into cutting head to prevent dust.
After protective glass assembly injects cutting head; under the upper cover in protective glass chamber and the effect of lower cover; gland 3, protective lens 2, elastic seal ring 4 will be close together; can not play; under the effect of cutting gas pressure, the upper labial surface of elastic seal ring 4 and the lower surface of protective lens 2 will be close together, and the lower labial surface of elastic seal ring 4 and the upper surface of lower cover will be close together; thus seal, to ensure that cutting gas can not leak.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
