Description

Technical Field

[0001] This utility model relates to the technical field of crucible centering and installation, and in particular to a simple crucible centering and leveling device. Background Technology

[0002] A crucible is a tool used to process single-crystal silicon. During operation, the crucible needs to be coaxially aligned with the water tank and guide pillars, requiring centering and alignment. Currently, this centering and alignment is done manually by operators. Manual operation is difficult to control, and the alignment process is time-consuming and labor-intensive, resulting in low production efficiency. Utility Model Content

[0003] The present invention aims to address the shortcomings of the prior art by providing a simple crucible centering and leveling device.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A simple crucible centering and leveling device includes a centering platform with its upper and lower surfaces completely parallel. The bottom of the centering platform has a groove, and a bolt fixing hole passes through the groove and the upper surface of the centering platform. The top of the centering platform has a coaxial sleeve.

[0006] The upper part of the outer wall of the sleeve is provided with a variable diameter section, the diameter of which gradually increases from top to bottom.

[0007] The top outer wall of the variable diameter section has a chamfered structure.

[0008] The bottom cross-sectional area of ​​the sleeve is smaller than the area of ​​the upper surface of the centering platform.

[0009] The beneficial effects of this utility model are: the utility model has a simple structure and can quickly and easily perform centering operations on the crucible, water box, and guide column, with good centering effect. Attached Figure Description

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] A simple crucible centering and leveling device, such as Figure 1 As shown, it includes a centering platform 1, a groove 2, a bolt fixing hole 3, and a sleeve 4.

[0018] The upper and lower surfaces of the centering platform 1 are completely parallel. The bottom of the centering platform 1 is provided with a groove 2. A bolt fixing hole 3 passes through the groove 2 and the upper surface of the centering platform 1. The top of the centering platform 1 is provided with a coaxial sleeve 4.

[0019] The upper end of the outer wall of the sleeve 4 is provided with a variable diameter section 41. The diameter of the variable diameter section 41 gradually increases from top to bottom. The top outer wall of the variable diameter section 41 is provided with a chamfer structure to facilitate the insertion of the crucible and avoid damage to the inner wall of the crucible.

[0020] The bottom cross-sectional area of ​​sleeve 4 is smaller than the area of ​​the upper surface of centering platform 1.

[0021] There are two bolt fixing holes 3, which are symmetrically arranged about the central axis of the centering platform 1.

[0022] The dimensions of groove 2 correspond to the surface of the water box.

[0023] When using this utility model, the groove 2 on the lower surface of the centering platform 1 is placed horizontally on the surface of the water box. The groove 2 is tightly engaged with the outer circle of the upper surface of the water box. The centering platform 1 is fixed by the bolts in the bolt fixing holes 3. The water box is raised to the lower edge of the crucible, and the sleeve 4 is inserted into the crucible. The crucible is supported by the upper surface of the centering platform 1. After the crucible is supported, the coaxiality and parallelism of the three can be automatically determined. Finally, the crucible is fixed in the current position.

[0024] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
