[0024] Further, the positioning piece includes a plurality of arc clamping plates 10 equidistantly arranged inside the shell 1, the top of each of the plurality of arc clamping plates 10 is fixedly connected with a lifting threaded sleeve 11, the top of each of the plurality of lifting threaded sleeves 11 extends to above the shell 1 outside and is rotatably connected therewith, the top of each of the plurality of lifting threaded sleeves 11 extends to inside the installation shell 13 and is rotatably connected therewith, and the front surface of the installation shell 13 is fixedly connected with a controller 21 for controlling the entire device.

[0025] The shell 1 serves as the outer shell of the entire device, protects the internal components, and provides a stable working environment. The lifting plate 2 is slidingly arranged inside the shell 1 and can be adjusted in height as needed to accommodate heating rods of different specifications. The arc heating seats 4 are equidistantly arranged on the top of the lifting plate 2 and are used for placing the silicon carbide heating rod bodies 5 to ensure that each heating rod is uniformly heated. The positioning piece (arc clamping plate 10) is located on the top of the silicon carbide heating rod body 5 and is slidingly connected to fix the heating rod. This design ensures that the heating rod maintains a stable position during heating. The lifting threaded sleeve 11 is fixedly connected to the top of the arc clamping plate 10 and extends to above the shell 1 outside and inside the installation shell 13, allowing the height of the arc clamping plate 10 to be adjusted by rotation to achieve an automated clamping and releasing process. The installation shell 13 is fixed on the top of the shell 1 and accommodates and protects the lifting threaded sleeve 11 and other related components. The controller 21 is located on the front surface of the installation shell 13 and is responsible for controlling the operation of the entire device.

[0026] Furthermore, a measuring plate 6 is fixedly connected to the rear side of the inner wall of the housing 1, and multiple temperature sensors 7 are fixedly connected to the front surface of the measuring plate 6 at equal intervals. The front surfaces of the multiple temperature sensors 7 are in contact with the rear ends of the multiple silicon carbide heating rod bodies 5.

[0027] The measuring plate 6 is fixedly connected to the rear side of the inner wall of the housing 1, serving as the mounting platform for the temperature sensor 7. This ensures that the temperature sensor 7 is in a stable position and is not affected by external interference. The temperature sensor 7 is equidistantly arranged on the front surface of the measuring plate 6, and its front end is in contact with the rear end of the silicon carbide heating rod body 5. This arrangement ensures that the temperature of each heating rod is monitored individually, providing accurate temperature data.

[0028] Furthermore, multiple electric push rods 3 are fixedly connected at equal intervals to the center of the bottom of the inner wall of the housing 1, and the top telescopic ends of the multiple electric push rods 3 are fixedly connected to the bottom of the lifting plate 2.

[0029] Multiple electric push rods 3 are equidistantly arranged at the center of the bottom of the inner wall of the housing 1, and their top telescopic ends are fixedly connected to the bottom of the lifting plate 2. This layout ensures that the lifting plate 2 can rise or fall smoothly to accommodate silicon carbide heating rods of different specifications. By controlling the telescopic movement of the electric push rods 3, the height of the lifting plate 2 can be precisely adjusted.

[0031] The door 8 is rotatably connected to the front surface of the housing 1, and can be opened and closed to facilitate the operator to place or remove the silicon carbide heating rod body 5.

[0032] Furthermore, each of the multiple lifting threaded sleeves 11 is internally threaded with a lifting threaded rod 12, the top of the multiple lifting threaded rods 12 extending above the outside of the multiple lifting threaded sleeves 11 and rotatably connected to the top of the inner wall of the mounting shell 13.

[0033] The lifting threaded sleeve 11 has internal threads that form a threaded connection with the lifting threaded rod 12. These lifting threaded sleeves 11 are fixed to the top of the arc-shaped clamping plate 10 and extend to the upper exterior of the housing 1 and the interior of the mounting housing 13. The top of the lifting threaded rod 12 extends to the upper exterior of multiple lifting threaded sleeves 11 and is rotatably connected to the top of the inner wall of the mounting housing 13. This allows the lifting threaded rod 12 to drive the lifting threaded sleeves 11 to move up and down when it rotates.

[0034] Furthermore, a second worm gear 14 is fixedly sleeved on the upper surface of multiple lifting threaded rods 12, and two second worm gears 14 arranged in front and behind are meshed with the same second worm 15 on one side. Multiple second worms 15 are equidistantly arranged inside the mounting shell 13.

[0035] The second worm gear 14 is fixedly sleeved on the upper surface of each lifting threaded rod 12 to transmit rotational motion to the lifting threaded rod 12. The second worm gear 15 is equidistantly arranged inside the mounting housing 13 and meshes with the two second worm gears 14 arranged in front and behind. This allows one second worm gear 15 to drive two second worm gears 14 at the same time, thereby realizing the simultaneous control of the two lifting threaded rods 12.

[0036] Furthermore, multiple lifting limit rods 16 are fixedly connected to the front and rear sides of the top of the housing 1 at equal intervals. The top of the multiple lifting limit rods 16 is fixedly connected to the top of the inner wall of the mounting housing 13, and one side of the multiple lifting threaded sleeves 11 is slidably connected to the multiple lifting limit rods 16.

[0037] Guided by the lifting limit rod 16, the lifting threaded sleeve 11 can move precisely in a straight line in the vertical direction, reducing the possibility of lateral deviation and ensuring that the arc-shaped clamping plate 10 applies uniform pressure to the heating rod. The lifting limit rod 16 sets maximum and minimum stroke limits to prevent the lifting threaded sleeve 11 from exceeding the allowable range, thereby protecting the internal components of the equipment from damage and ensuring the safety of the operators.

[0038] Furthermore, a first worm gear 18 is rotatably connected to the center of the mounting housing 13, and a first worm wheel 17 is fixedly sleeved on the center of the surface of multiple second worm gears 15. The bottom of the multiple first worm wheels 17 is meshed with the top of the first worm gear 18. A power motor 19 is fixedly connected to the left side of the outer wall of the mounting housing 13. The output end of the power motor 19 is fixedly connected to one end of the first worm gear 18. A protective cover 20 is provided outside the power motor 19, and one side of the protective cover 20 is fixedly connected to the left side of the outer wall of the mounting housing 13.

[0039] The first worm gear 18 is rotatably connected to the center of the mounting housing 13, serving as the core component of the entire transmission system. The first worm wheel 17 is fixedly sleeved on the center of the surface of each second worm gear 15 and meshes with the top of the first worm gear 18. This allows one first worm gear 18 to simultaneously drive multiple second worm gears 15, thereby controlling the movement of multiple lifting threaded rods 12. The power motor 19 is fixedly connected to the left side of the outer wall of the mounting housing 13, with its output end fixedly connected to one end of the first worm gear 18. The power motor 19 provides driving force, causing the first worm gear 18 to rotate, thus driving the entire transmission system. The protective cover 20 is located outside the power motor 19 and fixedly connected to the left side of the outer wall of the mounting housing 13, providing protection against external objects entering and affecting motor operation, while also improving safety.

[0040] After the operator connects the power, the controller 21 begins initialization, checks the status of all sensors and actuators to ensure that the system is in normal working condition, and places multiple silicon carbide heating rods 5 into the arc-shaped heating base 4 in sequence, ensuring that each heating rod is located on the corresponding heating base. The operator closes the shell door 8 through the handle 9 to ensure that a closed working environment is formed inside the equipment to prevent external interference.

[0041] The first worm gear 18 is driven to rotate by the power motor 19, which in turn drives multiple second worm gears 15 to rotate synchronously via the first worm wheel 17. This causes multiple lifting threaded sleeves 11 to descend, lowering the lifting plate 2 to its lowest position for easy clamping of the silicon carbide heating rod body 5. As the lifting plate 2 descends, the arc-shaped clamping plate 10 contacts the silicon carbide heating rod body 5 and gradually applies clamping force through a sliding connection until the preset height and pressure are reached, ensuring the heating rod is firmly fixed. The controller 21 issues a command to power on the silicon carbide heating rod body 5, initiating heating. Multiple temperature sensors 7 mounted on the measuring plate 6 monitor the temperature changes of each heating rod in real time and feed the data back to the controller 21. If an abnormal temperature is detected, the controller 21 will immediately take measures (such as cutting off the power) to protect the equipment. Due to the design of the first worm gear 18 and the first worm wheel 17, all lifting threaded rods 12 can move synchronously, ensuring that each heating rod receives uniform and consistent treatment, improving the consistency and reliability of the test results.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
