[0004] When existing equipment tests the viscosity of lubricating oil, it simply heats or cools the lubricating oil and then uses a viscosity detector to detect the viscosity of the lubricating oil. Under such a detection method, the temperature and state of the lubricating oil are easily affected by other factors, which in turn causes errors in the data measured by the viscosity detector, affecting the detection results of the equipment. Summary of the invention

[0005] The object of the present invention is to provide a lubricating oil viscosity testing device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a lubricating oil viscosity testing device, comprising a bottom plate, a placing frame is fixedly connected to the top of the bottom plate, a moving device is fixedly connected to the top of the bottom plate, a slider is movably connected to the outer wall of the moving device, and a connecting plate 1 is fixedly connected to the outer wall of the slider, and further comprising: The testing mechanism comprises a circular plate 1 fixedly connected to the bottom of a connecting plate 1, a viscosity detector fixedly connected to the inner wall of the circular plate 1, a gear 1 fixedly connected to the output end of the viscosity detector, a connecting ring 1 fixedly connected to the outer wall of the circular plate 1, a connecting ring 2 fixedly connected to the bottom of the circular plate 1, a shell fixedly connected to the inner wall of the shell, a heating ring fixedly connected to the inner wall of the connecting ring 2, a central component fixedly connected to the inner wall of the connecting ring 2, a rotating mechanism rotatably connected to the inner wall of the connecting ring 1 through a bearing, and the viscosity detector drives the gear 1 to rotate, thereby providing power for the rotation of the rotating mechanism.

[0007] According to the above technical solution, a hollow column 1 is fixedly connected to the inner wall of the shell, a notch 1 is provided on the inner wall of the hollow column 1, and a notch 2 is provided on the inner wall of the hollow column 1. The notch 1 and the notch 2 are used for testing the flow of high-temperature gas inside the mechanism. By setting up the testing mechanism, a heating ring is used to heat the lubricating oil during the viscosity test of the lubricating oil at different temperatures performed by the equipment. The heating ring of the equipment is placed at the center of the storage frame, so that the disassembly component on the rotating mechanism is just in the vicinity of the heating ring. In this way, the oil temperature near the disassembly component can be more accurately controlled, thereby improving the accuracy of the equipment detection value.

[0008] According to the above technical solution, the rotating mechanism includes a circular plate 2, the outer wall of the circular plate 2 is rotatably connected to the connecting ring 1 through a bearing, the inner wall of the circular plate 2 is rotatably connected to the connecting ring 2 through a bearing, the top of the circular plate 2 is fixedly connected with a gear 2, the gear 1 is meshed with the gear 2, a through hole is provided at the top of the circular plate 2, and a disassembly component is movably connected to the inner wall of the through hole, and the rotation of the gear 2 drives the disassembly component on the circular plate 2 to revolve, so that the disassembly component is subjected to the viscosity of the lubricating oil. By setting up a rotating mechanism, when the viscosity detector is in operation, its rotor drives the gear 1 to rotate, and the rotating gear 1 then drives the gear 2 to rotate, thereby prompting the disassembly component to revolve. Since the viscosity detector detects the viscosity of the lubricating oil based on the torque required when the rotor rotates, and the radius of the gear 1 is smaller than that of the gear 2, according to the torque amplification principle, the torque output when the gear 2 rotates can be amplified. In this way, the range of values ​​that can be detected by the device during the detection process can be widened, and then the torque generated is calibrated by the geometric reduction method, which effectively improves the accuracy of the detection value of the device.

[0009] According to the above technical solution, the inner wall of the circular plate 2 is fixedly connected with an elastic component 1, and the end of the elastic component 1 away from the connecting ring 2 is fixedly connected with a locking head, and the outer wall of the locking head is movably connected to the through hole, and the locking head is used to lock the position of the disassembly component.

The hollow U-shaped plate can facilitate the disassembly component to be embedded in the through hole, and the blocking column can fix the position of the disassembly component with the cooperation of the locking head. By setting the disassembly component, after the equipment completes the detection of the lubricating oil, the equipment must be inspected. Perform a comprehensive cleaning. If it is not cleaned in time, the residual substances may be mixed into the lubricating oil in the subsequent testing process, causing the lubricating oil to be contaminated and affecting the accuracy of the test results. However, due to the external rotating mechanism of this equipment, many cleaning dead corners are inevitably produced on the equipment. In view of this situation, by conveniently disassembling the disassembly components, it can greatly facilitate the staff to go deep into every corner of the equipment for detailed cleaning, effectively avoiding the appearance of cleaning dead corners, and ensuring that the equipment can always remain clean in the subsequent lubricating oil testing work, thereby ensuring the accuracy of the test values.

[0011] According to the above technical solution, the inner wall of the hollow U-shaped plate is movably connected with a ramp plate, the bottom of the ramp plate is fixedly connected with a connecting plate three, the top of the connecting plate three is fixedly connected with an elastic component three, the top of the elastic component three is fixedly connected to the connecting plate two, the bottom of the connecting plate three is fixedly connected with a connecting plate four, and the bottom of the connecting plate four is fixedly connected with a force column. By setting the force column, the front end of the force column has a larger thickness, and then the thickness gradually decreases along the rotation direction. When the force column revolves, this design can not only ensure that it can normally withstand the viscosity generated by the lubricating oil, but also effectively prevent outside air from mixing into the lubricating oil, thereby improving the accuracy of the equipment detection value. The descent or rise of the ramp plate can change the extension state of the blocking column.

[0012] According to the above technical solution, the central component includes a fixed plate, the outer wall of the fixed plate is fixedly connected to the connecting ring 2, the inner wall of the fixed plate is fixedly connected with a connecting tube 1, the inner wall of the fixed plate is fixedly connected with a connecting tube 2, and the bottom of the fixed plate is fixedly connected with a push rod. The connecting tube 1 is used for the entry of gas, and the connecting tube 2 is used for the discharge of gas. By setting the central component, when the equipment needs to cool the lubricating oil, not only will the heating function of the heating ring be shut down, but also the ventilation gap near the heating ring will be opened. With the help of rapid ventilation, the heat dissipation of the heating ring can be accelerated, so that the temperature conditions of the equipment can meet the requirements of the next round of detection more quickly, thereby effectively improving the overall detection efficiency of the equipment.

[0013] According to the above technical solution, the inner wall of the hollow column one is movably connected to the hollow column two, and the outer wall of the hollow column two is provided with a connecting groove, which penetrates the hollow column two and extends to the top of the hollow column two, the inner wall of the connecting groove is movably connected to the connecting pipe two, the inner wall of the hollow column two is movably connected to the connecting pipe one, the outer wall of the hollow column two is sleeved with a spring, the bottom of the spring is fixedly connected to the hollow column two, and the top of the spring is fixedly connected to the outer shell, when the hollow column two is at the bottom, it can block the flow of gas, and after the hollow column two is lifted, the gas can flow normally.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention sets a testing mechanism. When the equipment performs viscosity testing on the lubricating oil at different temperatures, a heating ring is used to heat the lubricating oil. The heating ring of the equipment is placed at the center of the storage frame, so that the disassembly component on the rotating mechanism is just in the vicinity of the heating ring. In this way, the oil temperature near the disassembly component can be controlled more accurately, thereby improving the accuracy of the equipment detection value.

[0015] 2. The present invention sets a rotating mechanism. When the viscosity detector is in operation, its rotor drives gear one to rotate, and the rotating gear one in turn drives gear two to rotate, thereby causing the disassembly assembly to revolve. Since the viscosity detector detects the viscosity of the lubricating oil based on the torque required when the rotor rotates, and the radius of gear one is smaller than that of gear two, according to the principle of torque amplification, the torque output when gear two rotates can be amplified. In this way, the range of values ​​that can be detected by the device during the detection process can be widened, and then the generated torque is calibrated by a geometric reduction method, which effectively improves the accuracy of the device's detection value.

[0016] 3. The present invention sets a disassembly component. After the equipment completes the detection of the lubricating oil, the equipment must be thoroughly cleaned. If it is not cleaned in time, the residual material may be mixed into the lubricating oil during the subsequent detection process, thereby causing the lubricating oil to be contaminated and affecting the accuracy of the detection results. However, since this equipment adopts an external rotating mechanism structure, it is inevitable that many cleaning dead corners are produced on the equipment. In view of this situation, by conveniently disassembling the disassembly component, it can greatly facilitate the staff to go deep into every corner of the equipment for detailed cleaning, effectively avoiding the occurrence of cleaning dead corners, and ensuring that the equipment can always remain clean in the subsequent lubricating oil detection work, thereby ensuring the accuracy of the detection value.

[0017] 4. The present invention sets a load-bearing column, which has a relatively large thickness at the front end and then gradually decreases in thickness along the rotation direction. When the load-bearing column revolves, this design can ensure that it can normally withstand the viscosity generated by the lubricating oil and effectively prevent external air from mixing into the lubricating oil, thereby improving the accuracy of the equipment's detection values.

[0018] 5. The present invention sets a central component. When the equipment needs to cool the lubricating oil, it will not only shut down the heating function of the heating ring, but also open the ventilation gap near the heating ring. By means of rapid ventilation, the heat dissipation of the heating ring can be accelerated, so that the temperature conditions of the equipment can meet the next round of detection requirements more quickly, thereby effectively improving the overall detection efficiency of the equipment.
