Abstract
The invention discloses a fixing device for cutting a lens, which comprises a base and a plurality of positioning parts. The base comprises a side wall and a bottom part which is vertical to the side wall. A plurality of clamping grooves which pass through inner and outer surfaces of the side wall are formed on the side wall at equal intervals; the clamping grooves are used for accommodating a runner head of a lens ejection piece and comprise two opposite inner walls. A positioning part is arranged on each inner wall; and two positioning parts in each clamping groove are oppositely arranged. Each positioning part comprises a positioning piece and an elastic element which is connected with the positioning piece. The positioning piece is fixed on the inner wall of the clamping groove through the elastic element and is used for fixing the lens ejection piece in the clamping groove. The fixing device for cutting the lens can effectively prevent uneven shearing surface of a plastic lens because the positioning piece has a vertically downward pressure on the lens ejection piece.
Description
Technical field
The present invention relates to a kind of fixture, relate in particular to a kind of fixture for cutting lens.
Background technology
At present glass lens is used widely in camera lens because of the lower photograph at mobile phone and digital camera of cost.In the prior art, the manufacturing process of glass lens is generally: by the eyeglass injection part of Jet forming machine ejaculation with glass lens, by mechanical arm this eyeglass injection part is taken out from Jet forming machine again, and be positioned in the cutting lens machine and plastic lens to be sheared row's dish get final product.Shown in Figure 1 is a schematic diagram with the eyeglass injection part 1 of glass lens that is penetrated by Jet forming machine, it has the semi-finished product of the glass lens 11 of eight injection mo(u)ldings, these eight glass lens 11 can one-shot forming, and be connected with runner stub bar 13 by running channel stub bar 12, glass lens 11 forms eight connecting portions 14 with running channel stub bar 12.But present cutting lens machine in the vertical direction does not have fixture, therefore in shear history, easily cause whole eyeglass injection part 1 perk, make the uneven cutting edge of plastic lens 11 whole, therefore must shear through next step work of leftover pieces, cause having prolonged production procedure, increased production cost.
Summary of the invention
In view of this, be necessary to provide a kind of whole fixture that is used for cutting lens of uneven cutting edge that prevents that effectively plastic lens from causing because of shearing.
A kind of fixture for cutting lens, it comprises a pedestal and a plurality of location division.Described pedestal comprises a sidewall and a bottom perpendicular to described sidewall.The draw-in groove of the surfaces externally and internally that the described sidewall of a plurality of perforations is set of described sidewall equal intervals.Described draw-in groove is used for the runner stub bar of an accommodating eyeglass injection part.Described draw-in groove comprises relative two inwalls and a diapire, and described diapire connects described two inwalls, and described two inwalls are drawn close gradually towards the direction near described diapire.On described each inwall a location division is set.Two location divisions in each draw-in groove are oppositely arranged.Described location division comprises positioning piece and the flexible member that is connected with described keeper.Described keeper all is fixed on the inwall of described draw-in groove by described flexible member, and described keeper is triangle, and described keeper offsets towards surface and the described runner stub bar of described diapire, so that described eyeglass injection part is fixed in the described draw-in groove.
Fixture for cutting lens of the present invention, on the inwall of described draw-in groove, connect positioning piece by flexible member, after the runner stub bar of an eyeglass injection part is put into described draw-in groove, described keeper has straight down a pressure to described runner stub bar, make cutter in the process that described plastic lens is sheared, described runner stub bar can perk, thereby prevents that the plastic lens on the eyeglass injection part is whole because of the uneven cutting edge that shearing causes.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 2 and Fig. 3, be a kind of fixture 100 for cutting lens that embodiment of the present invention provides, it is used for fixing an eyeglass injection part 1 in the process of carrying out cutting lens.Described fixture 100 for cutting lens comprises a pedestal 110 and a plurality of location division 120.
Described pedestal 110 is a bowl structure, and it comprises a sidewall 111 and a bottom 112 perpendicular to described sidewall 111.The draw-in groove 113 of the inversion trapezoidal shape of the surfaces externally and internally that the described sidewall 111 of a plurality of perforations is set of described sidewall 111 equal intervals.The runner stub bar 13(that described draw-in groove 113 is used for accommodating described eyeglass injection part 1 sees Fig. 6).Please further consult Fig. 4 and Fig. 5, described draw-in groove 113 comprises an opening 114, one diapires 115 and two relative inwalls 116.Described opening 114 be arranged in parallel with described diapire 115.Described diapire 115 is connected described two inwalls 116.Described inwall 116 is drawn close gradually towards the direction near described diapire 115.All along the direction of described sidewall 111 location division 120 is set in the position near described opening 114 on the described inwall 116.Two location divisions 120 in each draw-in groove 113 are oppositely arranged.In the present embodiment, described sidewall 111 equal intervals arrange four draw-in grooves 113.Two inwalls 116 of described draw-in groove 113 are two inclined-planes, and two inwalls 116 in the described draw-in groove 113 equate with the angle of horizontal plane.Be appreciated that described draw-in groove 113 also can be leg-of-mutton shape.
Such as Fig. 4 and shown in Figure 5, described location division 120 comprises positioning piece 121 and the flexible member 122 that is connected with described keeper 121.Described keeper 121 all is fixed on the inwall 116 of described draw-in groove 113 by described flexible member 122.As shown in Figure 6, when described eyeglass injection part 1 was placed on described fixture 100 for cutting lens, described keeper 121 offseted towards the side 123 of the described bottom 112 runner stub bar 13 with described eyeglass injection part 1.In the present embodiment, described keeper 121 is leg-of-mutton shape.Described flexible member 122 is a spring, end 130(towards the inwall 116 of described draw-in groove 113 of described spring 122 sees Fig. 4) be fixed on the screw, then this screw hammers in the described inwall 116, thereby described flexible member 122 is fixed on the described inwall 116.
Use procedure in described fixture 100 for cutting lens, the resistance that first the runner stub bar 13 of described eyeglass injection part 1 is overcome described keeper 121 presses downward to described fixture 100 for cutting lens, when described eyeglass injection part 1 is sheared, because the runner stub bar 13 of 121 pairs of described eyeglass injection parts 1 of described keeper has a downward pressure, make the described runner stub bar 13 can perk, make the edge of the plastic lens 11 of shearing out smooth.After shearing is finished, the resistance that described eyeglass injection part 1 overcomes described keeper 121 is upwards mentioned, take out from described fixture 100 for cutting lens.
Fixture for cutting lens of the present invention, on the inwall of described draw-in groove, connect positioning piece by flexible member, after the runner stub bar of described eyeglass injection part is put into described draw-in groove, described keeper has straight down a pressure to described runner stub bar, make cutter in the process that described plastic lens is sheared, described runner stub bar can perk, thereby prevents that the plastic lens on the eyeglass injection part is whole because of the uneven cutting edge that shearing causes.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
