Description

Technical Field

[0001] The utility model relates to the field of single crystal furnace processing, in particular to a furnace barrel outer wall accessory installation and positioning device. Background Art

[0002] A single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polysilicon in an inert gas environment (primarily nitrogen and helium) and grow dislocation-free single crystals using the Czochralski method. The structure of a single crystal furnace generally consists of a furnace body, melt agitator, temperature control system, vacuum system, pressure control system, and pulling machine. The furnace body includes the furnace bottom, furnace drum, and furnace cover. The furnace drum is a crucial component of the single crystal furnace and affects its operation.

[0003] At present, in the process of processing the furnace drum of a single crystal furnace, after the processing of the furnace drum body is completed, some accessories need to be installed on the outer wall of the furnace drum so that the furnace drum can be coordinated with the other components of the single crystal furnace. This requires that the corresponding mounting plates be welded in advance at the corresponding positions of the outer wall of the furnace drum for the installation of accessories. When welding the mounting plates, there are fixed requirements for the position of the mounting plates, which are mainly reflected in the vertical distance requirements between the mounting plates and the end of the furnace drum. The existing processing is to measure the position before processing, then mark the lines, and finally weld the mounting plates. The whole process is very cumbersome and the processing efficiency is relatively low. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a furnace outer wall accessory installation and positioning device which is convenient for installing accessories.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a furnace outer wall accessory installation and positioning device, the innovation of which is:

[0006] A positioning base plate, wherein the positioning base plate is semicircular and the inner wall of the positioning base plate is in contact with the outer wall of the furnace drum;

[0007] The distance plate is arranged on the positioning bottom plate, and is a rectangular plate extending along the long axis direction of the furnace drum, and a gap is left between the distance plate and the inner wall of the positioning bottom plate in the radial direction.

[0008] Furthermore, there are several distance plates distributed along the circumferential direction of the circle where the positioning base plate is located, and each distance plate is set on the same side of the positioning base plate, and the vertical distance between the top end of each distance plate and the positioning base plate is different.

[0009] Furthermore, the distance plate is provided with a plurality of positioning through holes.

[0010] The advantages of the present invention are that: the positioning device of the present invention can quickly locate the position of the mounting plate for accessory installation through the mutual cooperation between the positioning base plate and the distance plate, which greatly shortens the positioning time of the mounting plate, facilitates processing, and improves processing efficiency; and the design of leaving a gap in the radial direction between the distance plate and the inner wall of the positioning base plate means that after the positioning base plate is attached to the outer wall of the furnace drum, a certain gap can be left between the distance plate and the furnace drum, which is more conducive to the fixation of the mounting plate.

[0011] By arranging a plurality of distance plates on the same positioning base plate and controlling the different sizes of the distance plates, the same positioning device can be used to position the mounting plates at different positions on the same furnace drum.

[0012] The design of the positioning holes on the distance plate makes it convenient to mark and locate points on the outer wall of the furnace through the positioning holes, so as to facilitate the rapid positioning and installation of the subsequent mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the furnace outer wall accessory installation and positioning device of the present invention.

[0014] Figure 2 This is a top view of the furnace outer wall accessory installation and positioning device of the present invention. DETAILED DESCRIPTION

[0015] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0016] like Figure 1 、 Figure 2 The furnace outer wall accessory installation and positioning device shown includes:

[0017] The positioning base plate 1 is in a semicircular shape, and the inner wall of the positioning base plate 1 fits the outer wall of the furnace drum.

[0018] The distance plate 2 arranged on the positioning base plate 1 is a rectangular plate and extends along the long axis direction of the furnace drum. There is a gap in the radial direction between the distance plate 2 and the inner wall of the positioning base plate 1. The radial direction is the radial direction of the furnace drum after the positioning base plate 1 is fitted with the outer wall of the furnace drum. This design allows a certain gap to be left between the distance plate 2 and the furnace drum after the positioning base plate 1 is fitted with the outer wall of the furnace drum, which is more conducive to the fixation of the mounting plate.

[0019] There are several distance plates 2 distributed along the circumference of the circle surrounding the positioning base plate 1. Each distance plate 2 is located on the same side of the positioning base plate 1, and the top of each distance plate 2 has a different vertical distance from the positioning base plate 1. By arranging multiple distance plates 2 on the same positioning base plate 1 and controlling the different sizes of each distance plate 2, the same positioning device can be used to position mounting plates at different locations on the same furnace drum.

[0020] Several positioning holes 21 are also provided on the distance plate 2. The design of the positioning holes 21 on the distance plate 2 facilitates marking and positioning on the outer wall of the furnace drum through the positioning holes 21 for quick positioning and installation of the subsequent mounting plate.

[0021] When using the positioning device of the present invention to install the mounting plate, first fit the inner wall of the positioning base plate 1 with the outer wall of the furnace, and fit the end face of the positioning base plate 1 on the side where the distance plate 2 is not installed with the flange surface of the end of the furnace, and then select the corresponding distance plate 2 according to the position requirement of the positioning plate to be installed, and place the end of the mounting plate against the end of the distance plate 2 on the side away from the positioning base plate 1, and the positioning of the mounting plate is completed. For some mounting plates that cannot be installed directly, such as mounting plates that need to be installed at an angle, the positioning through holes 21 on the distance plate 2 can be used to mark and locate the points first, and then the positioning base plate 1 can be removed to install the mounting plate, which greatly shortens the positioning time of the mounting plate.

[0022] The positioning device of the utility model can quickly locate the position of the mounting plate for installing accessories through the mutual cooperation between the positioning base plate and the distance plate, greatly shortening the positioning time of the mounting plate, facilitating processing and improving processing efficiency.

[0023] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
