Description
Technical field
The utility model relates to clamp art more particularly to a kind of fixtures for measuring the unilateral type of aspherical mirror.
Background technique
As shown in Figure 1, being usually provided with aspherical eyeglass 10 in mobile lens, eyeglass includes aspheric face 11 and sets
It is placed in the boss 12 at facial 11 edges of aspheric.Aspherical lens need to carry out before factory optical measurement, common optical measurement
Method includes the face type using laser scanning eyeglass, and pushes over out the mathematical model of eyeglass.
It needs that eyeglass is fixed using fixture during laser scanning.Common fixture is pallet, and eyeglass is placed
In the accommodation groove of pallet.During laser scanning, since pallet can reflect laser, and then scanning essence will affect
Degree, reduces the accuracy rate of mathematical model.
Utility model content
The technical problems to be solved in the utility model is that it is aspherical to provide a kind of measurement according to above-mentioned the deficiencies in the prior art
The fixture of eyeglass face type, to improve the accuracy rate of laser scanning precision and mathematical model.
The technical solution of the utility model is as follows:
A kind of fixture measuring the unilateral type of aspherical mirror, includes fixed plate and several tweezers；The fixed plate surface is set
Accommodating several fixed long holes of through-hole are equipped with, several fixed long holes are distributed in around the accommodating through-hole；The tweezers outer end
It is removably connected to the fixed long hole, the tweezers inner end is set in the accommodating through-hole.
Further, the tweezers include upper tweezer tablet and lower tweezer tablet, and the upper tweezer tablet outer end and lower tweezer tablet outer end pass through
Screw bolt and nut is removably connected to the fixed long hole.
Further, the fixed plate is provided with the height adjustment column being detachably connected, and the height adjustment column passes through up and down
Wear the fixed plate.
Further, height adjustment column side is provided with threaded hole；The fixed plate surface is provided with several jacks,
The fixed plate side is provided with the connecting hole being connected to the jack；The height adjustment column is inserted in the jack, is adjusted
It saves bolt and passes through the connecting hole and threaded hole locking, the height adjustment inserting column is made detachably to be set to the fixation
Plate.
Further, several tweezers are angularly distributed using the accommodating through-hole as the center of circle.
Compared with prior art, the utility model has the following beneficial effects: eyeglass is fixed on accommodating by tweezers by (1)
In through-hole, laser will not be reflected after scanning to eyeglass by fixture, improve the accuracy rate of scanning accuracy and mathematical model；(2) tweezers
Outer end is removably connected to fixed long hole, it can be achieved that the position of tweezers is adjusted, and is adapted to the eyeglass of different size, improves applicable
Property；(3) by the height adjustment column of replacement different height, it can be achieved that the adjustment of fixture height, is adapted to the eyeglass of different size, mentions
High applicability.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Fig. 2, embodiment provided by the utility model, a kind of fixture measuring the unilateral type of aspherical mirror, include
Fixed plate 20 and several tweezers 30.20 surface of fixed plate is provided with the accommodating several fixed long holes 22 of through-hole 21, several fixed long holes
22 are distributed in around accommodating through-hole 21；30 outer end of tweezers is removably connected to fixed long hole 22, and 30 inner end of tweezers is set to accommodating
In through-hole 21.In the present embodiment, three tweezers 30 are that the center of circle is angularly distributed to accommodate through-hole 21.
Tweezers 30 include upper tweezer tablet 31 and lower tweezer tablet 32, and upper 31 outer end of tweezer tablet and lower 32 outer end of tweezer tablet pass through bolt and spiral shell
Mother is removably connected to fixed long hole 22.
As shown in figure 3, fixed plate 20 is provided with the height adjustment column 40 being detachably connected, about 40 height adjustment column runs through
Fixed plate 20.
40 side of height adjustment column is provided with threaded hole 41；20 surface of fixed plate is provided with several jacks 23, fixed plate side
Face is provided with the connecting hole 24 being connected to jack 23；Height adjustment column 40 is inserted in jack 23, is adjusted bolt and is passed through connecting hole
24 lock with threaded hole 41, and height adjustment column 40 is made detachably to be set to fixed plate 20.
The use state of the present embodiment: the setting of eyeglass 10 is in accommodating through-hole 21,30 inner end clamping projections 12 of tweezers.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
