[0025] Working principle: The hydrothermal kettle is fixedly installed on the hydrothermal kettle limiting device. When the kettle cover of the hydrothermal kettle is removed, the limiting device driving mechanism controls the hydrothermal kettle limiting device to move to the bolt tightening position, and the lifting driving mechanism drives the bolt tightening machine to descend, so that the bolt tightening machine is connected with the kettle cover bolts on the kettle cover of the hydrothermal kettle, and the output end of the bolt tightening machine rotates in the opposite direction to tighten the kettle cover bolts on the kettle cover to loosen the kettle cover, and then the lifting driving mechanism controls the overall ascent, and the limiting device driving mechanism controls the hydrothermal kettle to move to the kettle cover tightening position, and the lifting driving mechanism controls the kettle cover tightening machine to descend, and separately controls the opening and closing of the kettle cover clamp 6, so that the kettle cover clamp 6 clamps the kettle cover, and the clamp driving mechanism drives the kettle cover clamp 6 to rotate, and at the same time, the lifting driving mechanism drives the kettle cover clamp 6 to rise, so that the kettle cover is screwed out.

[0026] When it is necessary to tighten the kettle cover on the hydrothermal kettle body, the lifting drive mechanism controls the kettle cover clamping jaws 6 to descend, so that the kettle cover cooperates with the bottle mouth thread of the hydrothermal kettle body. At the same time, the clamping jaw drive mechanism controls the kettle cover clamping jaws 6 to rotate, so that the kettle cover is screwed into the hydrothermal kettle body. Then the kettle cover clamping jaws 6 open and move upward, and the limit device drive mechanism drives the hydrothermal kettle to move to the bolt tightening station. The lifting drive mechanism controls the bolt tightening machine to move downward, so that the bolt tightening machine is connected with the kettle cover bolts, and the output end of the bolt tightening machine rotates in the positive direction, and the kettle cover bolts are tightened with a constant torque, thereby completing the installation of the kettle cover on the hydrothermal kettle body.

[0027] The utility model is provided with a double-station operating system, which switches between two stations through a water-heating kettle limit device, and then controls the lifting and lowering of the bolt tightening machine and the kettle cover tightening machine through a lifting drive mechanism, so that the bolts of the kettle cover can be loosened or tightened stably through the bolt tightening machine, and the kettle cover can be taken out or screwed in through the kettle cover tightening machine, so that the kettle cover can be automatically removed and installed, and the operation accuracy and efficiency are improved: the automated fixing, positioning, locking, loosening and other operations make the operation of the water-heating kettle more accurate and efficient. The accuracy of each step of the operation is ensured by machine control, thereby improving the efficiency of production and experiments, and reducing labor costs and risks. The automated operating system reduces the need for manual intervention, reduces labor costs, and reduces the risk of accidents caused by manual operation. The degree of intervention of the operator is reduced, and the possibility of operation errors and safety risks is also reduced. The consistency and reliability of the operation can be improved, and the application of the automated operating system ensures the consistency of the operation and reduces the variability of manual operation. Each operation can be performed according to the preset program, thereby improving the reliability and stability of the operation.

[0028] In one embodiment, please refer to Figure 1 to Figure 2 As shown, the kettle cover clamp 6 is connected to the clamp driving mechanism through a coupling 7. The clamp driving mechanism is a clamp driving motor 2, which can be specifically a second stepping motor. The clamp driving mechanism can also be a hydraulic motor. A first hydrothermal kettle sensor is arranged on the coupling 7. The first hydrothermal kettle sensor can detect the relative position of the clamp and the hydrothermal kettle, and detect whether the clamp clamps the hydrothermal kettle. The bolt tightening machine includes a bolt sleeve 4 and a sleeve driving mechanism. The sleeve driving mechanism is used to drive the bolt sleeve 4 to rotate, and the inner wall surface of the bolt sleeve 4 matches the shape of the kettle cover bolt on the hydrothermal kettle. For example, when the kettle cover bolt is a hexagonal bolt, the bolt sleeve 4 is also a hexagonal sleeve, and the bolt sleeve 4 can be clamped with the kettle cover bolt. The inner wall surface of the bolt sleeve 4 is completely fitted with the outer wall surface of the kettle cover bolt, so that when the bolt sleeve 4 rotates, it can stably drive the kettle cover bolt to rotate together, and there will be no slipping between the bolt sleeve 4 and the kettle cover bolt.

[0029] In this embodiment, the bolt sleeve 4 is slidably engaged with the output shaft of the sleeve drive mechanism, and the sliding direction is parallel to the axial direction of the output shaft of the sleeve drive mechanism. A sliding entrance is provided on the output shaft of the sleeve drive mechanism, through which the bolt sleeve 4 can smoothly slide onto the output shaft of the drive mechanism. The sleeve drive mechanism is a sleeve drive motor 1, which can specifically be a first stepper motor. The sleeve drive mechanism can also be hydraulic.

[0030] A spring 5 is sleeved on the outside of the sleeve driving mechanism, one end of the spring 5 is fixedly connected to the sleeve driving mechanism, and the connection method can be that a retaining ring is fixedly sleeved on the outside of the output shaft of the sleeve driving mechanism, the retaining ring is fixedly connected to the spring 5, and the other end of the spring 5 is connected to the bolt sleeve 4. When the bolt sleeve 4 contacts the kettle cover bolt, the bolt sleeve 4 is pressed upward by the kettle cover bolt to compress the spring 5, so that the spring 5 is compressed and deformed, and moves upward along the axis of the output shaft of the sleeve driving mechanism. At this time, the bolt driving mechanism controls the bolt sleeve 4 to rotate until the bolt sleeve 4 is completely aligned with the kettle cover bolt. Under the driving force of the spring 5 and the deadweight of the bolt sleeve 4, the bolt sleeve 4 can be sleeved on the outside of the kettle cover bolt, so that the bolt sleeve 4 is clamped with the kettle cover bolt. At this time, when the sleeve driving mechanism drives the bolt sleeve 4 to rotate, it can stably drive the kettle cover bolt of the hydrothermal kettle to rotate together, thereby tightening or loosening the kettle cover.

The lifting drive motor 3 is fixedly connected to the fixed mounting plate 17 through a support column, and is fixedly connected to the screw 14 through the output shaft of the lifting drive motor 3. When the lifting drive motor 3 drives the screw 14 to rotate, the rotation of the screw 14 drives the sliding mounting plate 15 to move up and down along the axis of the column 12. The screw 14 is threadedly connected to the sliding mounting plate 15, and the screw 14 is parallel to the axis of the column 12.

[0034] In this embodiment, the tops of the two columns 12 are connected by a horizontal plate 13, and a through hole matching the size of the screw 14 is provided in the middle of the horizontal plate 13. The end of the screw 14 away from the lifting drive motor 3 is rotatably connected to the horizontal plate 13. The specific rotatable connection method can be that the screw 14 and the horizontal plate 13 are connected by a bearing, and the position of the screw 14 can be limited by the horizontal plate 13 to prevent the screw 14 from swinging. The lifting drive motor 3, the screw 14 and the sliding mounting plate 15 together constitute the lifting drive mechanism;

[0035] A motor sensor 19 is arranged on the horizontal plate 13. When the lifting drive mechanism drives the bolt tightening machine and the kettle cover tightening machine to rise to a certain position, the motor sensor 19 can receive information, control the lifting drive motor 3 to stop running at this time, and send a signal to the control system; a lifting sensor is also arranged on the column 12 to detect the position of the bolt sleeve 4.
