Description

Technical Field

[0001] This utility model relates to a furnace body processing device, and more particularly to a component processing device for a single crystal furnace. Background Technology

[0002] A single crystal furnace includes components such as the furnace cover, upper furnace cavity, furnace bottom plate, auxiliary chamber, lower furnace cavity, and water-cooled heat shield. Currently, during the processing of single crystal furnaces, the furnace cover, upper furnace cavity, and lower furnace cavity must maintain the roundness of their inner walls. In actual processing, in addition to the processing of these components themselves, other accessories, such as mounting bases and mounting plates, need to be welded to the inner or outer walls of the components. These accessories are welded after the furnace body components are formed. This can easily lead to a situation where, even if the inner wall roundness of the furnace body meets the requirements during the rolling process in the previous stage, deformation of the inner wall of the furnace body may occur during the subsequent welding of accessories, thus affecting the roundness of the inner wall of the furnace body. This requires secondary repair, which is very troublesome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a single crystal furnace component processing device that can ensure the roundness of the inner wall during furnace body processing.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a telescopic transport beam, the innovation of which lies in: including

[0005] The inner support assembly consists of several inner support plates arranged in a ring shape. The inner and outer walls of the inner support plates are both arc-shaped. The inner support plates are driven to move closer or further apart by an adjustment assembly.

[0006] The adjustment assembly includes an adjustment sleeve disposed within the annulus formed by the inner support plates. The adjustment sleeve is a hollow circular tube and is concentrically arranged with the annulus formed by the inner support plates. The adjustment sleeve is connected to each inner support plate by a connecting rod. One side of the connecting rod is connected to the inner wall of the inner support plate, and the other side passes through the adjustment sleeve and extends into the adjustment sleeve. A push block is also disposed inside the adjustment sleeve to drive the connecting rods to move synchronously. The push block is locked to the adjustment sleeve by a tightening bolt.

[0007] Furthermore, the push block and each connecting rod are coupled as follows: the outer wall of the push block fits against the inner wall of the adjusting sleeve, and a slot is opened on the outer wall of the push block to accommodate each connecting rod in a corresponding manner. The bottom surface of the slot is a driving slope, and the end face of the connecting rod that extends into the adjusting sleeve is a slope that fits against the driving slope.

[0008] Furthermore, a return spring is also provided between the connecting rod and the push block.

[0009] The advantages of this utility model are as follows: The internal support device of this utility model provides support for the inner wall of the furnace body through the internal support components. Whether it is the rolling of the furnace body or the subsequent processing of the furnace body, it can provide good support for the inner wall of the furnace body to ensure the roundness of the inner wall of the furnace body.

[0010] The design of the adjustment component uses the cooperation of the adjustment sleeve and the push block to cooperate with the inclined surface of the connecting rod. The action of the push block can drive all the connecting rods to move synchronously, thereby realizing the simultaneous adjustment of all the inner support plates. This ensures that the adjusted inner supports still remain on the same ring structure, eliminating the need for repeated adjustments and making adjustment more convenient.

[0011] The design of the reset spring between the connecting rod and the push block serves two purposes: firstly, it applies a certain reaction force to the connecting rod to ensure its stability and prevent it from easily wobbling or becoming unstable; secondly, it can drive the connecting rod to reset when the push block moves in the opposite direction, reducing adjustment time.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] like Figure 1 , Figure 2 The illustrated component processing apparatus for a single crystal furnace includes...

[0016] The inner support assembly consists of several inner support plates 1 arranged in a ring shape. The inner and outer walls of the inner support plates 1 are both arc-shaped. The inner support plates 1 are driven to move closer or further apart by an adjustment assembly.

[0017] The adjustment assembly includes an adjustment sleeve 2 disposed within the annulus formed by the inner support plates 1. The adjustment sleeve 2 is a hollow circular tube, and its center is concentric with the center of the annulus formed by the inner support plates 1. The adjustment sleeve 2 is connected to each inner support plate 1 by a connecting rod 3. The connecting rod 3 is a cylindrical rod, one side of which is welded and fixed to the inner wall of the inner support plate 1, and the other side of which passes through the adjustment sleeve 2 and extends into the adjustment sleeve 2. The adjustment sleeve 2 has a through hole for the connecting rod 3 to pass through. A push block 4 is also disposed inside the adjustment sleeve 2 to drive the connecting rods 3 to move synchronously. The push block 4 is locked to the adjustment sleeve 2 by a tightening bolt 5. The adjustment sleeve 2 has a threaded through hole for the tightening bolt 5 to pass through. After passing through the threaded through hole on the adjustment sleeve 2, the tightening bolt 5 abuts against the outer wall of the push block 4, thereby achieving relative fixation between the push block 4 and the adjustment sleeve 2.

[0018] The push block 4 and each connecting rod 3 are configured as follows: The push block 4 is a cylindrical structure. The outer circumference of the push block 4 is in contact with the inner wall of the adjusting sleeve 2. On the outer circumference of the push block 4, there are slots 41 that allow each connecting rod 3 to penetrate in a corresponding manner. The slots 41 extend along the axial direction of the push block 4, and the width of the slots 41 is greater than the diameter of the connecting rod 3. At the same time, on the outer circumference of the push block 4, there are through grooves that communicate with the slots 41 and allow the connecting rods 3 to move back and forth. The through grooves extend along the axial direction of the push block 4, and the width of the through grooves is the same as the diameter of the connecting rod 3. The bottom surface of the slots 41 is a driving inclined surface 42. The end face of the connecting rod 3 that extends into the adjusting sleeve 2 is an inclined surface 31 that is in contact with the driving inclined surface 42. The inclined surface 31 and the driving inclined surface 42 are wedge-shaped to allow the push block 4 to slide in the adjusting sleeve 2 and push the connecting rod 3 to move. The design of the adjustment component uses the cooperation of the adjustment sleeve 2 and the push block 4 to cooperate with the inclined surface 31 of the connecting rod 3. The action of the push block 4 can drive all the connecting rods 3 to move synchronously, thereby realizing the simultaneous adjustment of all the inner support plates 1. This ensures that the adjusted inner supports 1 still remain on the same ring structure, eliminating the need for repeated adjustments and making the adjustment more convenient.

[0019] A return spring 6 is also provided between the connecting rod 3 and the push block 4. An annular limiting plate 32 is also welded to the outer wall of the connecting rod 3 near the inclined surface 31. One side of the return spring 6 abuts against the annular limiting plate 32, and the other side abuts against the inner wall of the through groove of the push block 4. The design of the return spring 6 between the connecting rod 3 and the push block 4 serves two purposes: firstly, it applies a certain reaction force to the connecting rod 3 to ensure its stability and prevent it from easily shaking or becoming unstable; secondly, it can drive the connecting rod 3 to reset when the push block 4 moves in the opposite direction, reducing adjustment time.

[0020] Working principle: When in use, firstly, according to the required dimensions of the inner wall of the furnace, push the push block 4 back and forth in the adjusting sleeve 2, thereby pushing the connecting rod 3 to move so that each inner support plate 1 can be adjusted to a position that fits against the inner wall of the furnace. After adjustment, use the tightening bolt 5 to hold the push block 4 in place, thereby fixing the push block 4 and the adjusting sleeve 2, which also fixes the inner support plate 1, thus supporting the inner wall of the furnace.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
