Deficiency for above-mentioned prior art, the utility model provides a kind of seedholder that can be used for large size sapphire crystal growth, and its structure design is simple, and installation and removal are convenient, and practicality is stronger, is intended to solve the seed crystal that in current production, this process procedure occurs and comes off and problem of Cracking.Its technical scheme is as follows:
A seedholder, integral body is high temperature resistant miramint, it comprises:
Retaining sleeve, has the through hole of axial break-through, and this through hole is axially divided into two sections by it, is respectively thread segment and the canned paragraph that axially outwards shrinks; And adapting rod, comprise a location division that lays respectively at its axial two ends and a junction that is subject to outside piece-holder; Outside, wherein said location division has the outside screw with described thread segment coaxial cooperation; This location division has towards one end of described canned paragraph oppresses in treating the fixedly compression spring of seed crystal.
Preferred person as this programme, can have following improvement:
In preferred embodiment, described through hole is rotational symmetric form.
In preferred embodiment, the surface of revolution of described canned paragraph is circular cone side.
In preferred embodiment, its taper obliquity of the through hole of described canned paragraph is 6-8 °.
In preferred embodiment, described connection section comprises a collar flange of a body of rod of uniform size and this body of rod end.
In preferred embodiment, described body of rod maximum diameter is 8-10mm, and described location division maximum diameter is 28-30mm.
The beneficial effect that this programme brings has:
Can effectively guarantee the safe handling of seed crystal, thereby avoid seed crystal fracture, extend the work-ing life of seed crystal; Can make fast seed crystal calibration centering, the normal growth of the crystal of being more convenient for and effectively control, not only improved working efficiency and productive efficiency, also improved the access times of clamper, reduced growth cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Fig. 1 is the front elevational schematic of the utility model one embodiment;
Fig. 2 is the cross-sectional schematic of AA part embodiment illustrated in fig. 1.
Embodiment
As depicted in figs. 1 and 2, the schematic diagram of a kind of seedholder of the utility model.This integral body is high temperature resistant miramint, at this area miramint, has kind widely, as long as intensity and heatproof are appropriate to concrete high temperature occasion, all can adopt.It comprises:
Retaining sleeve 10, has the through hole 19 of axial break-through, and this through hole 19 is axially divided into two sections by it, is respectively thread segment 12 and the canned paragraph 11 that axially outwards shrinks.
