Description
Technical field
The utility model relates to a kind of crucible shove charge positioning devices, are mainly used for PVT silicon carbide monocrystal growth furnace crucible dress
Furnace positioning.
Background technique
When PVT method produces single-crystal silicon carbide, the crucible for growing monocrystalline will be placed in PVT silicon carbide monocrystal growth furnace.PVT
Various insulation constructions are provided in silicon carbide monocrystal growth furnace, the center of each insulation construction should be put in burner hearth center, crucible
It sets on heat preservation, crucible needs to manually adjust crucible to burner hearth center when placing.In the prior art place heat preservation and
Using the mode manually adjusted when crucible, the sequence usually manually adjusted is: small heat preservation is put into burner hearth bottom by 1., big to protect
Temperature is put into burner hearth, and 2. crucibles are put on small heat preservation, and 3. manually adjust crucible, heat preservation, determines crucible in burner hearth by estimating
Center.The adjustment process can not directly and accurately adjust crucible, and time-consuming, low efficiency, and since the judgement of naked eyes has
Sex-limited, crucible shove charge center deviations are big, and possible crucible is at the center of heat preservation, without leading to earthenware at the center of burner hearth
Crucible position inaccurate in furnace.When crucible will lead to electromagnetic induction heating in furnace interior biasing, crucible uneven heating is even, leads to temperature
Partially and influence crystal growth quality, and crucible shove charge center deviations it is big when also be easy damage heat preservation.
Summary of the invention
In view of the above defects of the prior art, the utility model provides that a kind of structure is simple, can quickly have
The crucible shove charge positioning device of effect positioning crucible shove charge center.
The utility model is achieved by the following technical solution: a kind of crucible shove charge positioning device, it is characterized in that: packet
Include cylindric positioning tool ontology, outer diameter and the PVT silicon carbide monocrystal growth furnace burner hearth internal diameter phase of the positioning tool ontology
Matching, the inner cavity top of the positioning tool ontology be it is cylindric, the lower part of the inner cavity of the positioning tool ontology is big mouth court
Under it is round table-like, the upper end of the positioning tool ontology has top cover portion, and the centre of the top cover portion of the positioning tool ontology is set
Circular hole A, the circular hole A, the circular cylinder shaped portion of the positioning tool ontology, the positioning for thering is diameter and crucible outer diameter to match
The round table-like part of tooling ontology is coaxially disposed, and is distinguished in the top cover portion of the positioning tool ontology in the two sides of the circular hole A
Equipped with handle.
In the utility model, the circular cylinder shaped portion of the inner cavity of positioning tool ontology and round table-like part are respectively used to long brilliant
Big heat preservation and small heat preservation in furnace are positioned, and circular hole A is for positioning crucible.Due to circular hole A, positioning tool ontology
Circular cylinder shaped portion, the round table-like part coaxial arrangement of positioning tool ontology and the outer diameter and PVT silicon carbide list of positioning tool ontology
Crystals growth furnace burner hearth internal diameter matches, therefore is convenient to determine crucible shove charge center by the utility model, guarantees to protect
Warm structure and crucible are in burner hearth center.When using the utility model shove charge, each heat preservation is put into burner hearth bottom first, so
The utility model is put into burner hearth afterwards, heat preservation is positioned, then crucible is put into the circular hole A in the utility model, it is complete
At crucible shove charge, finally the utility model is taken out.
Further, the top cover portion of the positioning tool ontology with a thickness of 10mm-50mm.
The beneficial effects of the utility model are: the utility model structure is simple, crucible shove charge is carried out by it, it can be accurate
Crucible shove charge center is positioned, guarantees the accuracy of crucible shove charge center, avoids the deviation that range estimation occurs, it can be effective
Guarantee that bushing position is accurate, reduces since crucible local derviation causes thermal field partially to the influence of crystal growth quality, and the damage to heat preservation, and
And crucible shove charge is carried out using the utility model, it is convenient to operate, and is greatly improved the efficiency of shove charge.The utility model effectively solves
The problems in PVT silicon carbide monocrystal growth furnace crucible shove charge positioning in the prior art.

Fig. 2 is the schematic top plan view of Fig. 1；
Fig. 3 is the left view schematic diagram of Fig. 1；
In figure, 1, positioning tool ontology, 2, circular hole A, 3, handle, 4, top cover portion, 5, circular cylinder shaped portion, 6, round table-like portion
Point.
Specific embodiment
The utility model is further described below by non-limiting embodiment and in conjunction with attached drawing:
As shown in the picture, a kind of crucible shove charge positioning device comprising cylindric positioning tool ontology 1, the positioning
The outer diameter of tooling ontology 1 matches with PVT silicon carbide monocrystal growth furnace burner hearth internal diameter.The upper end of the positioning tool ontology 1 has
There is top cover portion 4, the centre of the top cover portion 4 of the positioning tool ontology 1 is equipped with the circular hole A2 that diameter and crucible outer diameter match.Institute
The inner cavity top for stating positioning tool ontology 1 is circular cylinder shaped portion 5, and the lower part of the inner cavity of the positioning tool ontology 1 is big mouth court
