Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, and more specifically, to a clamping device for graphite silicon carbide crucibles. Background Art

[0002] A graphite silicon carbide crucible refers to a type of crucible fired from graphite, clay, silica, and pyrophyllite. Graphite silicon carbide crucibles are mainly used for melting non-ferrous metals such as copper, brass, gold, silver, zinc, and lead and their alloys. In actual use of graphite silicon carbide crucibles, a clamping device is often used to complete the clamping and movement of the graphite silicon carbide crucibles. The actual use has the advantages of simple operation, stable structure, and safe use.

[0003] The existing technology discloses a fixture for graphite silicon carbide crucibles with the publication number: CN218856760U. In this utility model, the clamping work is completed by driving a threaded rod to make the stabilizing block contact the inner wall of the graphite silicon carbide crucible. However, the radian of the contact surface of the stabilizing block is fixed, and the stabilizing block is fixedly installed, so the stabilizing block cannot be replaced, resulting in that the stabilizing block can only clamp graphite silicon carbide crucibles of the same size. Moreover, the number of stabilizing blocks used is two, which is difficult to ensure the stability during the clamping process of the graphite silicon carbide crucible. At the same time, when impurities adhere to the inner wall of the graphite silicon carbide crucible, there is no cleaning structure. When there are impurities between the stabilizing block and the graphite silicon carbide crucible, the stability of clamping the graphite silicon carbide crucible cannot be ensured.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides a graphite silicon carbide crucible clamping device, which has the following

[0018] Beneficial effects:

[0019] (1) The utility model adopts an air storage cavity and an air storage tank. When the clamping device for a graphite silicon carbide crucible is actually used, an operator holds the handle by hand and moves the mounting circular plate. When the mounting circular plate moves into the graphite silicon carbide crucible, the air pump is made to work by using the control panel. The air pump can fill the inside of the air storage tank with air through the air guide pipe. The air inside the air storage tank can enter the inside of multiple air storage cavities respectively through multiple connecting pipes. This part of the air can push multiple pistons respectively. The multiple pistons drive multiple concave plates and multiple arc-shaped abutting blocks to move through multiple connecting rods. At the same time, the multiple pistons respectively squeeze multiple telescopic springs. When the multiple arc-shaped abutting blocks contact the inner wall of the graphite silicon carbide crucible, the operator closes multiple first control valves by hand. At this time, by using the friction force between the multiple arc-shaped abutting blocks and the graphite silicon carbide crucible, the graphite silicon carbide crucible can be extracted. When it is necessary to separate from the graphite silicon carbide crucible, the operator opens and closes multiple first control valves and second control valves by hand. The multiple telescopic springs, under the action of their own elastic forces, can respectively push the multiple pistons. The multiple pistons can push the air inside the multiple air storage cavities back into the inside of the air storage tank through the multiple connecting pipes. The air inside the air storage tank can be discharged through the air outlet pipe. At the same time, the multiple concave plates and the multiple arc-shaped abutting blocks can perform a reset movement. By using the threaded cooperation between the two connecting screws on the same side and the four connecting nuts on the same side, the operator rotates the four connecting nuts on the same side clockwise and counterclockwise by hand, moves one arc-shaped abutting block on the same side away, and then moves a new set of arc-shaped abutting blocks between the two clamping plates on the same side. When the two clamping plates on the same side contact the new set of arc-shaped abutting blocks, the four connecting nuts on the same side are rotated in the reverse direction to complete the replacement of one set of arc-shaped abutting blocks. The replacement of the remaining sets of arc-shaped abutting blocks can be obtained in the same operation. By setting the air storage cavity and the air storage tank, the clamping structure with a corresponding radian can be replaced according to the use requirements, and the stability between the clamping structure and the graphite silicon carbide crucible can be increased, improving the practicality of the clamping device for the graphite silicon carbide crucible.

[0020] (2) The present utility model adopts a scraper. According to the above operations, the operator holds the handle with the hand and moves the mounting circular plate. When the mounting circular plate is moved into the graphite silicon carbide crucible, first, the operator moves multiple groups of scrapers away from each other by hand. When multiple groups of scrapers are respectively in known appropriate positions, using the multiple groups of threaded through holes and multiple groups of fastening bolts that are threaded and matched with each other, the operator rotates multiple groups of fastening bolts clockwise by hand. When one ends of multiple groups of fastening bolts respectively move into the interiors of multiple groups of jacks, using the control panel, the air pump is made to work. Multiple groups of pistons drive multiple groups of concave plates and multiple groups of arc-shaped abutting blocks to move through multiple groups of connecting rods. During this process, multiple groups of connecting rods simultaneously drive multiple groups of scrapers to move respectively. When the far ends of multiple groups of scrapers contact the inner wall of the graphite silicon carbide crucible, the handle is rotated. Through the mounting circular plate, multiple groups of connecting plates and multiple groups of sliding plates, multiple groups of scrapers can be driven to rotate. The rotating multiple groups of scrapers can scrape off the impurities adhering to the inner wall of the graphite silicon carbide crucible. After the impurities are cleaned up, multiple groups of fastening bolts are rotated counterclockwise, and multiple groups of scrapers are reset. Then, the clamping work of the graphite silicon carbide crucible can be carried out. Through the provided scraper, a cleaning structure is available, which can remove the impurities between the clamping structure and the graphite silicon carbide crucible, providing a guarantee for the stable use of the clamping device for the graphite silicon carbide crucible.

Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0038] In one embodiment, a handle 5 is installed on the upper part of the mounting circular plate 1.

[0039] Working principle:

[0040] When the clamping device for graphite silicon carbide crucible is actually used, the operator holds the handle 5 by hand and moves the mounting circular plate 1. When the mounting circular plate 1 is moved into the graphite silicon carbide crucible, the air pump 19 is operated by using the control panel. The air pump 19 can fill the air into the interior of the air storage box 3 through the air guide pipe 20. The air inside the air storage box 3 can enter the interior of the multiple gas storage chambers 2 through the multiple groups of connecting pipes 15. This part of the air can push the multiple groups of pistons 6 respectively. The multiple groups of pistons 6 drive the multiple groups of concave plates 8 and the multiple groups of arc-shaped resistance blocks 12 to move through the multiple groups of connecting rods 7. When used in this way, the multiple groups of pistons 6 squeeze the multiple groups of telescopic springs 13 respectively. When the multiple groups of arc-shaped resistance blocks 12 contact the inner wall of the graphite silicon carbide crucible, the operator closes the multiple groups of first control valves 16 by hand. The graphite silicon carbide crucible can be extracted by utilizing the friction between the multiple sets of arc-shaped resistance blocks 12 and the graphite silicon carbide crucible. When it is necessary to detach the graphite silicon carbide crucible, the operator opens and closes the multiple sets of first control valves 16 and the second control valves 18 by hand. The multiple sets of telescopic springs 13 can push the multiple sets of pistons 6 respectively under their own elastic force. The multiple sets of pistons 6 can push the air inside the multiple sets of gas storage chambers 2 back to the inside of the gas storage box 3 through the multiple sets of connecting pipes 15. The air inside the gas storage box 3 can be discharged through the outlet pipe 17. At the same time, the multiple sets of concave plates 8 and the multiple sets of arc-shaped resistance blocks 12 can perform a reset movement. The two sets of connecting screws 9 on the same side cooperate with the threads of the four sets of connecting nuts 11 on the same side. The operator rotates the four sets of connecting nuts 11 on the same side clockwise and counterclockwise by hand, and then A group of arc-shaped resistance blocks 12 on the same side are moved away, and then a new group of arc-shaped resistance blocks 12 are moved between the two groups of clamping plates 10 on the same side. When the two groups of clamping plates 10 on the same side contact the new group of arc-shaped resistance blocks 12, the four groups of connecting nuts 11 on the same side are rotated in the opposite direction to complete the replacement of one group of arc-shaped resistance blocks 12. The replacement of the remaining groups of arc-shaped resistance blocks 12 can be obtained by the same operation. Through the set air storage chamber 2 and air storage box 3, the clamping structure of the corresponding curvature can be replaced according to the use requirements, and the stability of the clamping structure and the graphite silicon carbide crucible can be increased, thereby improving the practicality of the clamping device for the graphite silicon carbide crucible. At the same time, according to the above operation, the operator holds the handle 5 with his hand and moves the mounting circular plate 1. When the mounting circular plate 1 is moved to the graphite silicon carbide crucible When inserting, first use hands to move away from multiple groups of scrapers 22. When multiple groups of scrapers 22 are in the known suitable positions, use multiple groups of threaded through holes 24 and multiple groups of fastening bolts 25 to cooperate with each other, and the operator rotates multiple groups of fastening bolts 25 clockwise by hand. When one end of multiple groups of fastening bolts 25 moves into multiple groups of jacks 26, use the control panel to make the air pump 19 work, and multiple groups of pistons 6 drive multiple groups of concave plates 8 and multiple groups of arc-shaped resistance blocks 12 to move through multiple groups of connecting rods 7. In this process, multiple groups of connecting rods 7 simultaneously drive multiple groups of scrapers 22 to move. When the ends away from multiple groups of scrapers 22 contact the inner wall of the graphite silicon carbide crucible, rotate the handle 5, and by installing the circular plate 1, multiple groups of connecting plates and multiple groups of slide plates 23, multiple groups of scrapers 22 can be driven to rotate.The rotating multi-group scraping plates 22 can scrape off the impurities adhering to the inner wall of the graphite silicon carbide crucible. After the impurities are cleaned, rotate the multi-group fastening bolts 25 counterclockwise, and then reset the multi-group scraping plates 22. After that, the graphite silicon carbide crucible can be clamped. By providing the scraping plates 22, a cleaning structure is available, which can remove the impurities between the clamping structure and the graphite silicon carbide crucible, providing a guarantee for the stable use of the clamping device for the graphite silicon carbide crucible.
