Description
Technical Field
The utility model belongs to crucible measurement field, concretely relates to measure thick device at bottom of crucible.
Background
Quartz crucible is the necessary container in the directional solidification technique of polycrystalline silicon, and the crucible can seriously influence the crucible at the thermal conduction rate of heating and radiating process because of the thickness of crucible bottom is too thick at the ingot casting in-process, and the crucible bottom is too thick can lead to melting and long brilliant time extension, consequently need carry out size detection to the finished product crucible at the preparation in-process of crucible, especially need carry out the management and control to the thick needs key at the bottom of the crucible. At present, in the process of detecting the bottom thickness of the crucible, the height difference between the inner bottom and the outer bottom of the crucible is mainly measured by a ruler or a tape measure, the method is low in measurement accuracy, reading is easy to cause inaccurate conditions due to artificial factors, and the conditions that base points are selected inconsistently are easy to occur when the base points are selected in the measurement process, so that the bottom thickness of the crucible is easy to measure and a large error exists.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides a measure thick device at bottom of crucible, the device can accurately measure the bottom of crucible thick, and can be convenient for the fixed base point, and measuring process is convenient, can be accurate measure the bottom of crucible thick.
In order to achieve the aim, the utility model provides a device for measuring the bottom thickness of a crucible, which comprises a micrometer, a base plate, a bracket and a standard rod;
the support is arranged on one side of the outer part of the base plate and comprises a vertical supporting beam fixedly arranged on a supporting surface and a transverse bearing beam rotatably connected to the upper end of the vertical supporting beam; the free end of the transverse bearing beam can reach the upper part of the base plate or be far away from the upper part of the base plate in the rotating process;
the micrometer is arranged at the inner end of the transverse bearing beam, and the axis of the fine adjustment knob on the micrometer is vertically arranged;
the standard rod is vertically arranged, and the upper end of the standard rod is fixedly connected with the lower end of the micrometer fine adjustment knob.
Preferably, the base plate is composed of a marble plate and supporting legs supported around the bottom of the marble plate.
Further, in order to facilitate reading of the measurement result, the micrometer is an electronic micrometer.
In the utility model, the bracket is composed of the vertical supporting beam and the transverse bearing beam which is rotatably connected at the upper end of the vertical supporting beam, so that the free end of the transverse bearing beam can conveniently reach or separate from the upper part of the base plate in the rotating process, and further the micrometer fixedly connected at the inner end of the transverse bearing beam can conveniently reach or separate from the upper part of the inner part of the crucible arranged above the base plate; through the fine setting knob fixed connection that makes on standard lever and the micrometer, can conveniently carry out the rapid survey through the mode of rotatory standard lever, because the height of standard lever can be measured in advance, the height of base plate can be measured in advance, the total height of support can be measured in advance, therefore when measuring, as long as the bottom of standard lever is contradicted and is arranged in the inner bottom of crucible on the base plate in, alright measure the end thickness of crucible fast through the convenient count of micrometer. The device can accurately measure the bottom thickness of the crucible, can conveniently fix the base point, is convenient for the measuring process, and can accurately measure the bottom thickness of the crucible.

Detailed Description
The present invention will be further explained below.
As shown in FIG. 1, the device for measuring the bottom thickness of the crucible comprises a micrometer 4, a base plate 2, a bracket 5 and a standard rod 3;
the bracket 5 is arranged on one side of the outer part of the base plate 2 and comprises a vertical supporting beam 6 fixedly arranged on a supporting surface and a transverse bearing beam 7 rotatably connected to the upper end of the vertical supporting beam 6; the free end of the transverse carrier bar 7 can reach above the base plate 2 or away from above the base plate 2 during rotation;
the micrometer 4 is arranged at the inner end of the transverse bearing beam 7, and the axis of a fine adjustment knob on the micrometer 4 is vertically arranged;
the standard rod 3 is vertically arranged, and the upper end of the standard rod is fixedly connected with the lower end of a fine adjustment knob of the micrometer 4.
Preferably, the base plate 2 is composed of a marble plate 9 and supporting legs 8 supported around the bottom of the marble plate 9. The upper end surface of the marble plate 9 is horizontally disposed.
In order to facilitate reading of the measurement result, the micrometer 4 is an electronic micrometer.
By making the bracket 5 consist of the vertical supporting beam 6 and the transverse bearing beam 7 which is rotatably connected at the upper end of the vertical supporting beam 6, the free end of the transverse bearing beam 7 can conveniently reach or separate from the upper part of the base plate 2 in the rotating process, and then the micrometer 4 which is fixedly connected at the inner end of the transverse bearing beam 7 can conveniently reach or separate from the upper part of the inner part of the crucible 1 which is arranged above the base plate 2; through the fine setting knob fixed connection that makes on standard rod 3 and the micrometer 4, can conveniently carry out the rapid survey through the mode of rotatory standard rod 3, because the height of standard rod 3 can be measured in advance, the height of base plate 2 can be measured in advance, the total height of support 5 can be measured in advance, therefore when measuring, as long as the bottom conflict of standard rod 3 is arranged in base plate 2 on the inner bottom of crucible 1, alright measure the end thickness of crucible 1 fast through the count convenience of micrometer 4. The device can accurately measure the bottom thickness of the crucible, can conveniently fix the base point, is convenient for the measuring process, and can accurately measure the bottom thickness of the crucible.
