Description

Technical Field

[0001] This utility model relates to the field of crucible clamp technology, specifically a crucible clamp that can withstand high temperatures of 1200 degrees Celsius. Background Technology

[0002] Here's an example of background technology for crucible clamps, which you can adjust according to your specific needs: In many industrial production and scientific research fields, such as metallurgy, chemical engineering, and materials science, crucibles, as key containers for holding high-temperature molten materials, have always been a focus of attention for their safe and precise clamping and handling. Early on, simple tools such as ordinary pliers and hooks were often used to operate crucibles. However, these traditional tools often failed to meet the requirements for stable and precise clamping in high-temperature environments. On the one hand, ordinary metal tools are prone to deformation and softening when exposed to temperatures often exceeding thousands of degrees Celsius around furnaces. This not only prevents them from firmly clamping the crucible but may also cause it to fall due to their own damage, leading to serious safety accidents and material losses. On the other hand, the lack of precise positioning and a stable clamping force adjustment mechanism makes it difficult to ensure the stability of the crucible during handling, easily causing material spillage and affecting production quality and experimental accuracy.

[0003] Patent publication number "CN221611825U" discloses "A special clamp for a high-temperature single-layer calcining square crucible, including a side plate, an L-shaped clamping plate rotatably connected to the bottom end of the side plate, a lever arm hinged to the top end of the side plate, and a telescopic rod fixedly connected to one side of the side plate. One end of the telescopic rod is sleeved with a rectangular sleeve, a connecting plate rotatably connected to the outer surface of the rectangular sleeve, a top seat rotatably connected to the top end of the lever arm, a horizontal plate fixedly connected to the outer surface of the side plate, and an electric push rod hinged to the lower surface of the horizontal plate." In this invention, when the telescopic rod extends or retracts into the rectangular sleeve, the ball bearings contact the rolling grooves on the upper and lower surfaces of the telescopic rod, reducing the frictional resistance between the telescopic rod and the rectangular sleeve. When it is necessary to pour out the solution from the square crucible, the electric push rod can be activated to drive the connecting plate, which in turn drives the rotating shaft, which in turn drives the L-shaped clamping plate, thereby causing the square crucible to flip, thus facilitating the pouring out of the solution from the square crucible.

[0004] In the aforementioned patent, the existing crucible clamps do not have good high-temperature resistance, which affects the crucible clamping effect and thus the overall performance.

[0005] To address this problem, the present invention provides a crucible clamp that can withstand temperatures up to 1200 degrees Celsius. Utility Model Content

[0008] Furthermore, a mounting flange is fixedly installed on the top of the fixing frame, and the mounting flange is welded to the fixing frame.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Reference Figures 1 to 3 This application provides a crucible clamp resistant to 1200 degrees Celsius, including a fixed frame 1. A clamping guide wheel 2 is fixedly installed on the inner side wall of the fixed frame 1. A clamping transmission helical gear 3 is provided on the inner side wall of the fixed frame 1. A trapezoidal lead screw 4 with positive and negative teeth is connected to the inner side of the fixed frame 1 through a bearing. A second clamping guide wheel 6 is provided on the inner side wall of the fixed frame 1. A guide wheel rail 7 is provided on the inner side wall of the fixed frame 1. An extended clamping rod 8 is fixedly installed on the inner bottom wall of the fixed frame 1. A mounting flange 5 is fixedly installed on the top of the fixed frame 1. The mounting flange 5 is welded to the fixed frame 1. The mounting flange 5 is rectangular in shape and has rounded corners. There are two extended clamping rods 8, which are arranged opposite to each other. A crucible body 9 is provided on the inner side wall of the extended clamping rod 8. The crucible body 9 is circular in shape and has an anti-slip layer on its surface. The anti-slip layer is connected to the crucible body 9 by a coating process.

[0029] In this embodiment, regarding the clamping and releasing actions, the inner wall of the fixed frame 1 is provided with a clamping transmission helical gear 3. When an external power drives it to rotate, the trapezoidal lead screw 4 with positive and negative teeth connected to it via bearings rotates accordingly. Due to its positive and negative tooth structure, it can drive related components to perform linear motion. At the same time, the clamping guide wheel 1 2 and clamping guide wheel 2 6 on the inner side of the fixed frame 1 roll along the guide wheel guide rail 7, providing precise guidance for the movement and ensuring the stability of the linear motion, thereby realizing the clamping or releasing operation. For the crucible clamping step, the two extended clamping rods 8 arranged opposite to each other on the inner bottom wall of the fixed frame 1 move closer or further away under the action of the above-mentioned transmission components. When the crucible needs to be clamped, the extended rods 8 are driven to move closer or further away. The long clamping rods 8 are close to each other, and their inner walls contact the circular crucible body 9. The anti-slip layer on the surface of the crucible body 9 is connected by a coating process, which can increase the friction between the crucible and the extended clamping rods 8, so that the crucible is firmly clamped and prevents it from slipping during handling. When released, the relevant components can be driven in the opposite direction. In terms of installation and fixation, the top of the fixing frame 1 is welded with a mounting flange 5, which is rectangular and has rounded corners, so as to facilitate docking with external equipment such as robotic arms and hoisting devices. The clamp is fixed to it by a suitable connection method such as bolt connection, so that the clamp can complete a series of operations such as crucible clamping and handling under the drive of external equipment, and the overall work of crucible clamping in high temperature environment is effectively carried out.

[0030] Working principle: Regarding clamping and releasing actions, the inner wall of the fixed frame 1 is equipped with a clamping transmission helical gear 3. When driven to rotate by external power, the trapezoidal lead screw 4 with positive and negative teeth connected to it via bearings rotates accordingly. Due to its positive and negative tooth structure, it can drive related components to perform linear motion. Simultaneously, the clamping guide wheel 1 2 and clamping guide wheel 2 6 on the inner side of the fixed frame 1 roll along the guide wheel rail 7, providing precise guidance for the movement and ensuring the stability of the linear motion, thereby realizing the clamping or releasing operation. For the crucible clamping stage, two oppositely arranged extended clamping rods 8 on the inner bottom wall of the fixed frame 1 move closer or further away under the action of the aforementioned transmission components. When the crucible needs to be clamped, the extended rods 8 are driven to move closer or further away. The long clamping rods 8 are close to each other, and their inner walls contact the circular crucible body 9. The anti-slip layer on the surface of the crucible body 9 is connected by a coating process, which can increase the friction between the crucible and the extended clamping rods 8, so that the crucible is firmly clamped and prevents it from slipping during handling. When released, the relevant components can be driven in the opposite direction. In terms of installation and fixation, the top of the fixing frame 1 is welded with a mounting flange 5, which is rectangular and has rounded corners, so as to facilitate docking with external equipment such as robotic arms and hoisting devices. The clamp is fixed to it by a suitable connection method such as bolt connection, so that the clamp can complete a series of operations such as crucible clamping and handling under the drive of external equipment, and the overall work of crucible clamping in high temperature environment is effectively carried out.
