Abstract
The utility model discloses a heterotypic lens fixing device, including the fixing base, its characterized in that: the fixing base middle part is upwards uplifted and is formed with the boss, the upper surface and the leading flank of boss set up the arcwall face as an organic whole, and this arcwall face matches the internal surface of laminating abnormal shape lens, still is equipped with the adsorption hole on the arcwall face, is equipped with the air supply entry on the fixing base trailing flank, is equipped with the air flue in the fixing base, and this air flue one end intercommunication adsorption hole, the other end intercommunication air supply entry. The utility model discloses it is rational in infrastructure, realize the stable fixed of heterotypic lens.
Description
Technical Field
The utility model relates to an improvement invention in the field of glasses manufacturing, in particular to an improvement invention of a fixing device for special-shaped lenses.
Background
Some sports goods such as goggles, some labor protection goods glasses and other glasses can use aspheric unconventional lenses, which are called as special-shaped lenses for short, and the special-shaped lenses are not easy to fix when being processed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a rational in infrastructure, fix a position stable heterotypic lens fixing device.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of heterotypic lens fixing device, including the fixing base, its characterized in that: the fixing base middle part is upwards uplifted and is formed with the boss, the upper surface and the leading flank of boss set up the arcwall face as an organic whole, and this arcwall face matches the internal surface of laminating abnormal shape lens, still is equipped with the adsorption hole on the arcwall face, is equipped with the air supply entry on the fixing base trailing flank, is equipped with the air flue in the fixing base, and this air flue one end intercommunication adsorption hole, the other end intercommunication air supply entry.
The air passage is L-shaped.
And the fixing seats corresponding to the left side and the right side of the boss are provided with mounting holes.
The beneficial effects of the utility model are that heterotypic lens fixing device after the improvement changes the spherical face of the ordinary lens of fixing base installation into the arcwall face of cooperation heterotypic lens to in order to prevent that heterotypic lens landing from the arcwall face, adopt the fixed lens of vacuum adsorption structure, the processing of being convenient for.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the structure of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. This kind of heterotypic lens fixing device, including fixing base 1, the upwards uplift in 1 middle part of fixing base is formed with boss 2, the upper surface and the leading flank of boss 2 set up arcwall face 3 as an organic whole, this arcwall face 3 matches the internal surface of the heterotypic lens 8 of laminating, still be equipped with adsorption hole 4 on the arcwall face 3, be equipped with air supply entry 5 on the 1 trailing flank of fixing base, be equipped with air flue 6 in the fixing base 1, 6 one end intercommunication adsorption hole 4 of this air flue, other end intercommunication air supply entry 5, 5 switch-on negative pressure air supplies of air supply entry are used for stably adsorbing the heterotypic lens of arranging in on arcwall face 3, the processing preparation of the heterotypic lens of being convenient for, after the processing preparation is accomplished.
The air passage 6 is L-shaped, and is convenient to machine and form.
And mounting holes 7 are formed in the corresponding fixing seats 1 on the left side and the right side of the boss 2 and used for fixing the mounting seats on a processing table.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
