In addition, manual operation increases labor intensity and reduces work efficiency, especially in batch testing, this problem is more prominent. In summary, the existing lubricating grease cylinder stability determination device has deficiencies in oil separation amount measurement accuracy and operation automation, which limits the accuracy and efficiency of lubricating grease stability test, and an accurate oil separation amount measurement device with automatic weighing function is urgently needed.

[0028] The rotating component comprises the roller 13. The roller 13 is located in the heating box 3. The two ends of the roller 13 are respectively in detachable connection with the first rotating shaft 12 and the second rotating shaft 17. The outer side wall of the roller 13 is fixedly connected with the lifting lug 14.

[0029] The servo electric cylinder 4 is fixedly installed above the top wall of the heating box 3. The output shaft of the servo electric cylinder 4 penetrates the top wall of the heating box 3. The output shaft of the servo electric cylinder 4 is provided with the hook 20. The output shaft of the servo electric cylinder 4 is fixedly installed with the weighing sensor 21. One end of the sensitive element of the weighing sensor 21 is bonded with the hook 20. After the roller 13 drives the lifting lug 14 to rotate by a certain angle, the hook 20 hooks the lifting lug 14.

[0030] The lubricating grease roller stability determination device further comprises a heating component. The control panel 2 is in control connection with the heating component. The heating component comprises the heating plate 8 and the temperature sensor 9. The heating plate 8 is fixedly installed on the inner bottom wall of the heating box 3. The temperature sensor 9 is fixedly installed on the inner side wall of the heating box 3. The heating component further comprises other existing components and electrical elements, such as the temperature controller and the fuse, to meet the implementation needs of electric heating. Here, no more details are given.

[0031] The roller 13 is used to hold the lubricating grease. The heating box 3 provides a controllable temperature environment for the lubricating grease roller 13. The heating plate 8 is used to heat the air in the heating box 3, so that the lubricating grease is at a set temperature condition to simulate the temperature working condition in the actual use environment. The temperature sensor 9 monitors the temperature in the heating box 3 in real time and feeds back the data to the control panel 2. The control panel 2 automatically adjusts the power of the heating plate 8 according to the feedback data to ensure that the temperature in the heating box 3 is constant, providing stable temperature conditions for the lubricating grease stability determination. The heating plate 8 uses the electric heating plate commonly used in the current market, such as ceramic electric heating plate, etc. The output shaft end of the servo motor 10 is in transmission connection (or coaxial fixed connection) with the first rotating shaft 12. The servo motor 10 drives the first rotating shaft 12 to rotate, and the first rotating shaft 12 drives the roller 13 to rotate, and the roller 13 drives the second rotating shaft 17 to rotate. The servo motor has precise speed control capability and can stably drive the roller 13 to rotate according to the rotating speed and time set by the control panel 2, so as to provide stable shear stress for the lubricating grease, thereby accurately simulating the stress state of the lubricating grease in actual use. The detachable connection between the roller 13 and the first rotating shaft 12 and the second rotating shaft 17 facilitates the disassembly of the roller 13, improving the flexibility and maintenance convenience of the device. During the rotation of the roller 13, the lubricating grease inside the roller 13 is subjected to shear stress and high temperature, simulating the application scene of the lubricating grease in actual application. The servo electric cylinder 4 drives the hook 20 to move up and down after starting, and when the hook 20 hooks the lifting lug 14, the hook 20 can lift or lower the roller 13 through the lifting lug 14. When the servo electric cylinder 4 lifts the roller 13 through the hook 20, the weighing sensor 21 weighs the roller 13 and the lubricating grease inside it. Through the accurate measurement of the weighing sensor 21, the operator can know the oil separation amount of the lubricating grease after high temperature rotation, so as to accurately evaluate the stability of the lubricating grease by combining the roller 13 rotating speed, oil temperature bearing and other parameters.

[0032] Specifically, the support cabinet 1 is fixedly installed with an encoder bracket 6, and the encoder bracket 6 is fixedly installed with a rotary encoder 5. The second rotating shaft 17 is sleeved with a code disc 18, and the detection part of the rotary encoder 5 is close to the code disc 18.

[0033] The second rotating shaft 17 drives the code disc 18 to rotate when rotating, and the rotary encoder 5 includes but is not limited to an incremental encoder. The pulse signal is generated through the marking line (light transmission / occlusion) on the code disc 18, and the position is calculated by relying on the counter. The rotary encoder 5 is used to detect the rotating speed of the second rotating shaft 17 and transmit the related data to the control panel 2. Through the real-time monitoring of the rotating speed of the second rotating shaft 17 by the rotary encoder 5, the control panel 2 can accurately control the rotating speed of the roller 13, ensure that the lubricating grease is subjected to stable shear stress during the determination process, and improve the accuracy of the determination result.

[0034] Specifically, the rotating component further comprises a cover 16, a first connecting head 15, and a second connecting head. The cover 16 is detachably mounted on the roller 13, the first connecting head 15 is fixedly mounted on the outer sidewall of the roller 13, and the second connecting head is fixedly mounted on the outer sidewall of the cover 16. One end of the first connecting head 15 is detachably connected with one end of the first rotating shaft 12. One end of the second connecting head is detachably connected with one end of the second rotating shaft 17.

[0035] The cover 16 is used to cover the roller 13, and the periphery of the cover 16 is sealed to prevent the lubricating grease from overflowing. The first rotating shaft 12, the first connecting head 15, the roller 13, the second connecting head, and the second rotating shaft 17 are on the same axis. When the first rotating shaft 12 rotates, the roller 13 is driven to rotate by the first connecting head 15, and the roller 13 drives the second rotating shaft 17 to rotate by the second connecting head.

[0036] Specifically, the control panel 2 includes, but is not limited to, one of an editable logic controller, a single-chip microcomputer, and a microprocessor.

[0037] The control panel 2 is electrically connected (including communication connection) with the servo electric cylinder 4, the rotary encoder 5, the heating plate 8, the temperature sensor 9, the servo motor 10, and the weighing sensor 21, respectively, and controls the start and stop of the servo electric cylinder 4, the heating plate 8, and the servo motor 10 to meet the needs of automatic control. The rotary encoder 5 is used to detect the rotating speed of the second rotating shaft 17 and transmit relevant data to the control panel 2. The temperature sensor 9 is used to detect the temperature in the heating box 3 and transmit relevant data to the control panel 2. The weighing sensor 21 is used to detect the weight of the rotating component and transmit relevant data to the control panel 2. The control panel 2 is internally provided with software programs such as a logic control program and a time sequence control program to meet the needs of automatic control of the entire device and the needs of relevant data detection and statistics. The control panel 2 receives temperature data from the temperature sensor 9, rotating speed data from the rotary encoder 5, and weight data from the weighing sensor 21, automatically controls the rotating speed of the servo motor 10, the heating power of the heating plate 8, and the action of the servo electric cylinder 4 according to the preset program and parameters, and ensures that the measurement process is accurately performed according to the set program.

[0038] Specifically, the heating box 3 is hingedly provided with a box door 7. The box door 7 is used to ensure the sealing of the heating box 3, so that the temperature in the heating box 3 can be stably maintained at a set value, thereby providing a good environmental condition for the lubricating grease stability measurement.

[0039] In use, first, the target temperature in the heating box 3 is set through the control panel 2, the heating plate 8 starts heating according to the instruction of the control panel, the temperature sensor 9 monitors the temperature in the box in real time and feeds back the data to the control panel. The control panel automatically adjusts the power of the heating plate according to the feedback data, so that the temperature in the box gradually rises and stabilizes at the set target temperature, thereby providing a stable temperature environment for the lubricating grease. Then, the operator loads the lubricating grease sample into the roller 13 and installs the roller on the first rotating shaft 12 and the second rotating shaft 17. The control panel starts the servo motor 10 according to the preset program, and the servo motor drives the roller 13 to rotate through the first rotating shaft 12 at the set rotating speed and time. During the rotation of the roller, the lubricating grease is subjected to shear stress and high temperature, thereby simulating the working condition in actual use.

[0040] Before and after heating the roller 13, the servo motor cylinder 4 hooks the lifting lug 14 on the outer wall of the roller through the hook 20 under the instruction of the control panel, and lifts the roller 13. The weighing sensor 21 measures the weight change of the roller 13 and transmits the data to the control panel 2. The control panel calculates the oil separation amount of the lubricating grease after high-temperature rotation according to the data of the weighing sensor 21. Through the oil separation amount combined with the rotating speed of the roller 13, the temperature of the oil, etc., the stability of the lubricating grease can be accurately evaluated.

[0041] At the same time, the rotary encoder 5 monitors the rotating speed of the second rotating shaft 17 in real time and transmits the data to the control panel 2. The control panel 2 accurately controls the rotating speed of the servo motor 10 according to the rotating speed data, so as to ensure the stability of the rotating speed of the roller 13, so that the lubricating grease is subjected to stable shear stress during the measurement, thereby further improving the accuracy of the measurement result.

[0042] During the entire measurement process, the control panel 2 serves as the core control unit and coordinates the operation of each component to realize automatic operation. The operator only needs to perform simple parameter setting on the control panel 2 and issue operation instructions, so as to complete the measurement of the stability of the lubricating grease. This highly automated operation mode not only improves the measurement efficiency, but also effectively avoids the influence of human factors on the measurement result, thereby improving the reliability and repeatability of the measurement.

[0043] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
