[0002] High-temperature furnaces, also known as muffle furnaces or experimental electric furnaces, are general-purpose equipment used in industrial and scientific research fields for heat treatment processes such as sample sintering, material annealing, and high-temperature experiments. They are mainly used in laboratories and industrial and mining enterprises in the fields of medicine, chemical industry, metallurgy, and materials science. Existing equipment for clamping and transferring materials in high-temperature furnaces generally lacks fully automated control capabilities adapted to mobile robots, requiring close-range manual operation (such as manually adjusting the equipment position and assisting in clamping and positioning). This results in workers being directly exposed to the high-temperature furnace body's heat dissipation, harmful gases inside the furnace, or high-temperature materials, which can easily lead to safety accidents such as burns and inhalation of harmful gases.

[0014] This application provides a clamping mechanism for gripping round products inside a high-temperature furnace. This effectively solves the problem that existing equipment for gripping and transferring materials inside high-temperature furnaces generally lacks fully automated control capabilities adapted to mobile robots. It requires manual close-range operation, which exposes operators to the high-temperature furnace heat dissipation, harmful gases, or high-temperature materials, making them prone to burns, inhalation of harmful gases, and other safety accidents. This equipment can achieve fully automated control by relying on a mobile robot, eliminating the need for manual contact with the high-temperature and high-risk furnace environment, greatly improving operational safety. At the same time, the transmission response is rapid, and the clamping action can be completed quickly, improving production efficiency. Example

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application effectively solves the technical problem that existing equipment for clamping and transferring materials in high-temperature furnaces generally lacks fully automated control capabilities adapted to mobile robots, requiring manual close-range operation. This results in operators being directly exposed to the high-risk environment of high-temperature furnace heat dissipation, harmful gases, or high-temperature materials, easily leading to safety accidents such as burns and inhalation of harmful gases. The overall concept is as follows: A clamping mechanism for gripping round products in a high-temperature furnace includes a quick-change disc 1, a connecting frame 2 connected to the lower end of the quick-change disc 1, and a clamping device arranged below the connecting frame 2. The fixture mounting frame 3 and the quick-change positioning pin 4 are provided. The fixture mounting frame 3 is provided with a first helical gear 5 and a second helical gear 6, which mesh together. The fixture mounting frame 3 is equipped with a drive motor 7, and the output shaft of the drive motor 7 is fixedly connected to the first helical gear 5. A lead screw 8 is connected to the second helical gear 6. The lead screw 8 includes a left-hand threaded section and a right-hand threaded section. Two fixture connectors 9 are threaded on the left-hand threaded section and the right-hand threaded section respectively. A sliding groove is opened at the lower end of the fixture mounting frame 3, and the two fixture connectors 9 can only slide horizontally in the sliding groove.

[0016] The fixture mounting frame 3 and the connecting frame 2 are quickly connected via the fixture quick-change positioning pin 4. Two rollers 10 are symmetrically arranged on each of the two fixture connecting heads 9, and both sets of rollers 10 are slidably installed in the fixture mounting frame 3. Each of the two fixture connecting heads 9 has a fixture head 11 for gripping round products. In use, the quick-change disc 1 can be mounted on a mobile robot. When it is necessary to grip round products inside the high-temperature furnace, the drive motor 7 can be started via the mobile robot. The drive motor 7 will drive the first helical gear 5 to rotate, and the first helical gear 5 will drive the second helical gear meshing with it. The rotation of the second helical gear 6 will drive the lead screw 8 to rotate, and the left-hand threaded section and the right-hand threaded section on the lead screw 8 will rotate synchronously. Under the rotation of the left-hand threaded section and the right-hand threaded section, the two clamping connectors 9 will slide towards the center in the sliding groove inside the clamping mounting frame 3. At this time, the two clamping connectors 9 can complete the clamping operation of the round products in the high-temperature furnace. This equipment can achieve fully automated control by relying on mobile robots, eliminating the need for manual contact with the high-temperature and high-risk furnace environment, greatly improving operational safety. At the same time, the transmission response is rapid, and the clamping action can be completed quickly, improving production efficiency.

[0017] A lifting flexible component 12 for driving the lifting of the clamp mounting frame 3 is also provided between the connecting frame 2 and the clamp mounting frame 3. The lifting flexible component 12 consists of a spring, a guide shaft, a bushing and a detection sensor. The bushing is nested in the lifting motion component. The guide shaft is perpendicularly inserted into the bushing and fixed to the base. The two are clearance-fitted. The bushing reduces the direct friction between the guide shaft and the lifting component through its low friction characteristics, while constraining the lifting direction to ensure that the lifting motion always proceeds along the axial direction of the guide shaft, avoiding the lifting component from swaying or jamming, and providing a precise trajectory framework for subsequent smooth lifting. The spring is sleeved on the outside of the guide shaft (or arranged parallel to the guide shaft), with its two ends connected to the base and the lifting component, respectively. During ascent, the spring is stretched / compressed as the lifting components move, balancing part of the lifting components' own weight, reducing force fluctuations during the lifting process, and making the lifting action smoother. During descent, when the lifting component approaches the target position, the spring contacts the target first and is compressed. Within the trajectory defined by the guide shaft, it absorbs the descent inertial force through elastic deformation, avoiding a rigid collision between the lifting component and the target, thus achieving a flexible bottoming out. Sensors are installed at key locations along the lifting trajectory (such as the upper / lower limit, or near the target workstation): As the lifting component moves along the guide shaft trajectory, the sensor monitors its position in real time; When the lifting component reaches the preset position (or the spring is compressed to a safe range), the sensor outputs an electrical signal to trigger the lifting action to stop, thus avoiding overshoot. At this time, the accurate detection of the sensor depends on the stable trajectory guaranteed by the guide shaft and bushing, ensuring that the detection signal is consistent with the actual lifting position.

[0018] To address the problems existing in the prior art, this utility model provides a clamping mechanism for gripping round products inside a high-temperature furnace. This equipment can be fully automated by relying on a mobile robot, eliminating the need for manual contact with the high-temperature and high-risk furnace environment, thus greatly improving operational safety. At the same time, the transmission response is rapid, enabling quick completion of the clamping action and improving production efficiency.

[0019] Working principle: The first step involves mounting the quick-change disc 1 onto a mobile robot. When it's necessary to clamp round products inside the high-temperature furnace, the drive motor 7 can be started via the mobile robot. The drive motor 7 will rotate the first helical gear 5, which in turn will rotate the second helical gear 6 meshing with it. The rotation of the second helical gear 6 will cause the lead screw 8 to rotate, and the left-hand and right-hand threaded sections on the lead screw 8 will rotate synchronously. The rotation of the left-hand and right-hand threaded sections will cause the two clamping connectors 9 to slide towards the center in the grooves inside the clamping mounting frame 3. At this time, the two clamping connectors 9 can complete the clamping operation of the round products inside the high-temperature furnace. This equipment can achieve fully automated control by relying on a mobile robot, eliminating the need for manual contact with the high-temperature and high-risk furnace environment, greatly improving operational safety. At the same time, the transmission response is rapid, and the clamping action can be completed quickly, improving production efficiency.

[0020] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
