Description

Technical Field

[0001] The utility model belongs to the technical field of crucible production, and in particular relates to a clamping device for producing a graphite crucible. Background Art

[0002] Graphite crucible, also known as copper melting bag, copper melting, etc., refers to a type of crucible made of graphite, clay, silica and wax stone. Graphite crucible is mainly used to melt non-ferrous metals and their alloys such as copper, brass, gold, silver, zinc and lead. In the use and production process, in order to prevent rapid cooling and cracking, it cannot be directly cooled down quickly, and needs to be placed on an asbestos net to cool slowly, which requires the use of a clamping device to transfer it.

[0003] After searching, the patent with application number 202221727517.7 discloses a hanger clamping device for graphite crucible production. This patent starts the bidirectional drive motor to drive the movable block threadedly connected to the screw at the output end of the bidirectional drive motor to move. With the movement of the movable block, the first pressure plate and the second pressure plate hinged on both sides of the movable block gradually approach and fix to the inner surface of the crucible to complete the support of the crucible. With this embedded clamping method, due to the smooth inner wall of the crucible, the clamping may be unstable and cause the crucible to slip, and the overall structure is relatively complex and the production cost is relatively high. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a clamping device for graphite crucible production, in which a servo motor drives two moving rods to move closer to or away from each other through a bidirectional screw, so that the arc surface of the crucible body is clamped by the clamping plate on the inner side of the horizontal end of the moving rod. The support-type clamping method can effectively prevent the crucible body from slipping during use, thereby improving the safety and stability during use. The overall structure of the device is simple, the required components are few, and the production cost is low.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The servo motor drives the two moving rods to move closer to or away from each other through the bidirectional screw, thereby clamping the curved surface of the crucible body. The support type clamping method adopts the support type clamping method, which can effectively avoid the crucible body from slipping off during use, thereby improving the safety and stability during use. The overall structure of the device is simple, the required components are few, and the production cost is low.

[0007] Furthermore, the height of the clamping plate is shorter than the height of the arc-shaped surface of the crucible body, which ensures that the crucible body can be placed normally during use and improves the stability of the crucible body when it is placed.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the servo motor drives the two moving rods to move closer to or away from each other through the bidirectional screw, so that the arc surface of the crucible body is clamped by the clamping plate on the inner side of the horizontal end of the moving rod. The support-type clamping method can effectively avoid the crucible body from slipping during use, thereby improving the safety and stability during use. The overall structure of the device is simple, the required components are few, and the production cost is low. The height of the clamping plate is shorter than the height of the arc surface of the crucible body, which ensures that the crucible body can be placed normally during use, thereby improving the stability of the crucible body when placed.
