Abstract
Crystal bar axis positioning device, be made up of base and the sliding seat two parts be arranged on base, left and right sides shaft screw in the middle part of sliding seat bottom surface is movably fixed on base, rear and front end in the middle part of sliding seat bottom surface is provided with the tilt adjustment screw of crystal bar, the upper design of sliding seat has the arc holddown groove of crystal bar, on the two ends axis direction of the medial surface of arc holddown groove, be symmetrically installed with the oscillation adjustment bar of crystal bar, hold-down screw is set with tensioning spring, its front end is fixed on the inner side of adjustment bar through the top of sliding seat, oscillation adjustment screw front end withstands on the rear and front end, inner side of adjustment bar through the top of sliding seat.In technique scheme, crystal bar is fixed on crystal bar axis positioning device, by regulating tilt adjustment screw and oscillation adjustment screw to make the geometrical axis locus of crystal bar on mould overlap with the position of optical axial, comparatively fast, accuracy is higher for adjustment and fixed speed.
Description
Technical field
The utility model belongs to crystal bar technical field of processing equipment, relates to a kind of crystal bar axis positioning device.
Background technology
Sapphire wafer is in process of manufacture, first the hair rod processed from crucible cuts polishing roughing, form a regular cylindrical crystal bar, crystal bar is fixed afterwards on mould, the locus of crystal bar geometrical axis is adjusted, then mould is taken on cylindrical skin grinder edging processing is carried out to the excircle of crystal bar, crystal bar geometrical axis is overlapped with optical axial, when guaranteeing wafer slice processing afterwards, radial and axially complete vertical.In prior art, used mould structure is adjusted to the locus of crystal bar geometrical axis simple, the side of crystal bar and the contact wire of bottom surface are encased inside thin slice, the left and right of crystal bar and the locus of above-below direction is regulated with the thin slice be encased inside, thus the space of adjustment crystal bar geometrical axis on mould, make it to overlap with the optical axial position of crystal bar.This method of adjustment, the functional die of employing is simple, and the limited precision of adjustment, operating efficiency is relatively low.
Summary of the invention
For in prior art, mould is adopted to fix crystal bar, and the method for crystal bar geometrical axis is adjusted by the method that thin slice is encased inside crystal bar side and bottom surface, there is the limited precision of adjustment, the relatively low problem of operating efficiency, the utility model provides a kind of crystal bar axis positioning device, be made up of base and the sliding seat two parts be arranged on base, left and right sides shaft screw in the middle part of sliding seat bottom surface is movably fixed on base, rear and front end in the middle part of sliding seat bottom surface is provided with the tilt adjustment screw of crystal bar, the upper design of sliding seat has the arc holddown groove of crystal bar, on the two ends axis direction of the medial surface of arc holddown groove, be symmetrically installed with the oscillation adjustment bar of crystal bar, hold-down screw is set with tensioning spring, its front end is fixed on the inner side of adjustment bar through the top of sliding seat, oscillation adjustment screw front end withstands on the rear and front end, inner side of adjustment bar through the top of sliding seat.
In technique scheme, crystal bar is fixed on crystal bar axis positioning device, by regulating tilt adjustment screw and oscillation adjustment screw to make the geometrical axis locus of crystal bar on mould overlap with the position of optical axial, comparatively fast, accuracy is higher for adjustment and fixed speed.
