Description

Technical Field

[0001] This utility model relates to the field of crucible equipment, and in particular to a crucible clamping device. Background Technology

[0002] Currently, in the graphite material production process, crucibles are placed on production lines such as tunnel kiln trolleys and conveyor rollers as containers for material sintering. The traditional method of placement involves using a gantry crane and manual assistance to place the crucibles in position. However, because the crucibles themselves are quite heavy, both manual handling and placement increase the workload of workers, and the positioning is not very precise, also posing certain safety hazards.

[0003] Therefore, how to develop a crucible clamping device has become a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, the present utility model provides a crucible clamping device that can automatically deliver crucibles.

[0009] The two gripper assemblies arranged opposite each other include a first connecting rod and a gripper hinged to the end of the first connecting rod. The tops of the two first connecting rods are hinged to each other, and the two grippers are hinged to each other at the middle of the grippers via a mandrel. The assembly also includes a cylinder, the top of which is hinged to the tops of the two first connecting rods, and the bottom of which is hinged to the mandrel.

[0010] A first driving mechanism is disposed on the mobile platform, and the first driving mechanism drives the crucible clamping mechanism to move in the vertical direction.

[0011] Furthermore, it also includes a second drive mechanism for driving the mobile platform to move horizontally, including a servo motor mounted on the mobile platform and a gear connected to the servo motor. Correspondingly, the frame is provided with a rack for meshing with the gear. When the gear is driven to rotate by the servo motor, it drives the mobile platform to move along the rack direction.

[0012] Furthermore, the first driving mechanism includes a hydraulic cylinder disposed on the mobile platform, a crossbeam is fixedly connected to the bottom of the hydraulic cylinder, and the crucible clamping mechanism is disposed at the bottom of the crossbeam.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] It should be noted that the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope of this utility model.

[0021] See Figure 1-2 An embodiment of the crucible clamping device of this utility model is shown, comprising: a frame 11, a moving platform 4, a crucible clamping mechanism 8, and a first drive mechanism. The frame 11 is a frame supported by four pillars to support the moving platform 4. The moving platform 4 is configured to move horizontally on the frame 11.

[0022] The crucible clamping mechanism 8 is used to clamp / release the crucible and includes: two opposing jaw assemblies, each including a first connecting rod 81 and a jaw 82 hinged to the end of the first connecting rod 81, the tops of the two first connecting rods 81 being hinged to each other, and the two jaws 82 being hinged to each other at the middle of the jaws 82 via a mandrel; and a cylinder 9, the top of which is hinged to the tops of the two first connecting rods 81, and the bottom of which is hinged to the mandrel.

[0023] A first driving mechanism is disposed on the mobile platform 4, and the first driving mechanism drives the crucible clamping mechanism 8 to move in the vertical direction.

[0024] When the crucible needs to be gripped during operation, cylinder 9 retracts, and the crucible gripping mechanism 8 fully opens the gripper assembly. At this time, the first drive mechanism drives the crucible gripping mechanism 8 to descend. Once it reaches the designated position, cylinder 9 extends, and the crucible gripping mechanism 8 clamps the crucible. Then, the first drive mechanism drives the crucible gripping mechanism 8 to rise. After the moving platform 4 moves the crucible to the designated position, the first drive mechanism drives the crucible gripping mechanism 8 to descend. Once it reaches the designated position, cylinder 9 retracts, and the crucible gripping mechanism 8 fully opens the gripper assembly, completely disengaging the gripper 82 from the crucible. At this time, the first drive mechanism drives the crucible gripping mechanism 8 to rise, and the entire crucible gripping mechanism 8 returns to its original position.

[0025] By setting up a crucible clamping mechanism 8, a movable moving platform 4, and a first driving mechanism that drives the crucible clamping mechanism 8 to move in the vertical direction, an automated crucible clamping system is formed. The system is reliable in clamping, stable in conveying, highly applicable, and efficient. It does not require manual handling, has a relatively simple structure, and is easy to manufacture, maintain, and promote.

[0026] In some preferred embodiments, a second drive mechanism is further included to drive the mobile platform 4 to move horizontally. This mechanism includes a servo motor 1 mounted on the mobile platform 4 and a gear connected to the servo motor 1. Correspondingly, a rack 5 is provided on the frame to mesh with the gear. When the gear is driven to rotate by the servo motor 1, it drives the mobile platform 4 to move along the direction of the rack 5. In other embodiments, a screw and nut mechanism or a chain and sprocket mechanism can also be used to drive the mobile platform 4 to perform horizontal linear reciprocating motion. Such structural variations still fall within the protection scope of this utility model.

[0027] In some preferred embodiments, the first driving mechanism includes a hydraulic cylinder 2 mounted on the moving platform 4. A crossbeam 7 is fixedly connected to the bottom of the hydraulic cylinder 2, and guide rods 3 are provided on both sides, passing through the moving platform to provide guidance. The crucible clamping mechanism 8 is located at the bottom of the crossbeam 7. At least two crucible clamping mechanisms 8 are configured, both located at the same bottom of the crossbeam 7. In other embodiments, the number of crucible clamping mechanisms 8 may be three or more; such variations still fall within the protection scope of this utility model.

[0028] In some preferred embodiments, a clamping plate 10 is provided on the inner side of the bottom of the gripper 82, and a damping layer is provided on the surface of the clamping plate 10 to increase the coefficient of friction and improve clamping stability. In other preferred embodiments, a suction cup is provided on the clamping plate 10, and the suction cup is connected to an external vacuum negative pressure component to provide greater clamping force through negative pressure suction.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
