Abstract
The utility model relates to a positioning fixture for cutting a large-outside diameter lens. The fixture comprises a positioning clamp and a lens, wherein a V-shaped structure composed of a convex plate is arranged on a panel of the positioning clamp; the V-shaped structure is matched with the outside diameter of the lens arranged on the panel of the positioning clamp, and an angular bisector of the V-shaped structure overlaps with an axle wire of the positioning clamp. The positioning fixture disclosed by the utility model has the characteristics that the structure is simple, the practicability is strong, the precision is high and the generality is wide.
Description
Technical field
The utility model relates to a kind of positioning fixture that cuts big external diameter eyeglass.
Background technology
In the optics cold working industry of present stage, the hole axle that generally adopts circular pilot hole to match with the eyeglass external diameter cooperates locator meams that big external diameter eyeglass is positioned cutting, with the slitting shape of circular eyeglass symmetry.Because between pilot hole and the eyeglass external diameter is running fit, space has between the two reduced bearing accuracy, causes cutting accuracy on the low side.And the pilot hole of a model can only be processed the eyeglass of same outer diameter as, can not process the eyeglass of various outer diameter, does not possess versatility.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, practical, and precision is high, and the positioning fixture of the wider big external diameter eyeglass of cutting of versatility.
The utility model is to solve through following technical proposal: these anchor clamps are on the positioning fixture panel, to be provided with the V-structure that is made up of flange; Cooperate with the eyeglass external diameter on being placed on the positioning fixture panel, the axis of the angular bisector of this V-structure and positioning fixture itself coincides.
The beneficial effect of the utility model is on the positioning fixture panel, to be provided with the V-structure that is made up of flange to cooperate with the eyeglass external diameter, makes the eyeglass that must cut reach pinpoint effect, and can process the eyeglass of various outer diameter, possesses versatility.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structure vertical view of the utility model embodiment.
Embodiment
As shown in the figure; The utility model embodiment comprises positioning fixture panel 1 and eyeglass 2; On positioning fixture panel 1, be provided with the V-structure that constitutes by flange 3a, 3b; Cooperate with eyeglass 2 external diameters on being placed on positioning fixture panel 1, angular bisector that this V-structure constitutes and positioning fixture panel 1 axis own coincide.As long as the variation of eyeglass 2 external diameters does not exceed the design allowed band, the central point of eyeglass 2 just can be positioned on the axis of positioning fixture panel 1 all the time, has realized accurate location.
In sum, the utlity model has simple in structurely, practical, precision is high, and the wider characteristics of versatility.
