Description

Technical Field

[0001] This invention relates to the field of viscosity testing technology, specifically a lubricating oil viscosity testing device. Background Technology

[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect the machinery and machined parts. Its main functions include lubrication, cooling, rust prevention, cleaning, sealing, and buffering. The viscosity of lubricating oil directly determines its performance and is an important indicator for evaluating its quality.

[0003] Existing lubricating oil viscosity testing equipment generally uses a rotating impeller and a resistance sensor to agitate the lubricating oil and measure the resistance applied to the lubricating oil to detect its viscosity. However, after each test, it is often necessary for personnel to manually clean the oil container and impeller, which is time-consuming, labor-intensive, and not conducive to quickly starting the next test, thus reducing the efficiency of continuous testing. Summary of the Invention

[0004] The purpose of this invention is to provide a lubricating oil viscosity testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An oil removal mechanism connected to a lifting and adjusting mechanism, the oil removal mechanism including a pitch-changing rotating mechanism connected to the lifting and adjusting mechanism, the pitch-changing rotating mechanism being connected to a multi-directional spray brush mechanism.

[0011] As a further improvement of the present invention: the variable pitch rotation mechanism includes a third motor fixedly connected to the suspension, a gear fixedly connected to the output end of the third motor, a gear meshing with a gear ring, two sets of rotating frames fixedly connected to the gear ring, an annular guide rail fixedly connected to the suspension and slidably connected to the rotating frames, a linear track fixedly connected to the rotating frames, a fourth motor fixedly connected to the linear track, a lead screw fixedly connected to the output shaft of the fourth motor, a slider threadedly connected to the lead screw and slidably connected to the linear track, and the slider connected to a multi-directional spray brush mechanism.

[0012] As a further improvement of the present invention: the upper end of the slewing frame is provided with a notch, and the shape of the notch is adapted to the shape of the suspension.

[0014] As a further improvement of the present invention: the base is fixedly connected with two sets of drainage grooves, which are arranged below the L-shaped brush layer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The lubricating oil to be tested is poured into the tank. Then, the lifting and adjusting mechanism drives the telescopic rotation mechanism to descend, allowing the protective shell to enter the lubricating oil. The telescopic rotation mechanism then rotates the protective shell, causing it to rotate via a rotating disc and a fixed plate. The fixed plate then rotates the resistance sensor. During this process, the lubricating oil applies resistance to the resistance sensor, which measures the resistance. The control panel records the resistance data. Afterward, the drain valve discharges the lubricating oil. An external liquid supply device is connected to a multi-directional spray brush mechanism to supply cleaning liquid. The lifting and adjusting mechanism first drives the pitch-changing rotation mechanism to rise, providing a cleaning solution for the pitch-changing rotation mechanism. The multi-directional spray brush mechanism rotates to provide space, and then the variable-pitch rotation mechanism drives the multi-directional spray brush mechanism to rotate towards the fixed plate. The multi-directional spray brush mechanism performs spraying and brushing operations, and the variable-pitch rotation mechanism adjusts the position of the multi-directional spray brush mechanism to brush the inner wall of the barrel. The telescopic rotation mechanism drives the protective shell to rotate, so that the protective shell drives the fixed plate to rotate through the rotating disk, causing the scraper to scrape the lubricating oil at the bottom of the barrel. When the rotating disk driven by the first motor rotates and the rotating disk drives the fixed plate to a flat state, the moving multi-directional spray brush mechanism performs spraying and brushing operations on the protective shell, rotating disk, fixed plate, resistance sensor, and scraper. This invention uses a combination of a stirring viscosity measuring mechanism and an oil removal mechanism to stir the lubricating oil and measure the resistance applied to the lubricating oil, thereby measuring the viscosity of the lubricating oil. Then, the invention automatically performs oil removal spraying and brushing operations, thereby achieving automatic measurement and automatic cleaning, improving detection efficiency.

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Example 1, see Figures 1 to 8 As shown, a lubricating oil viscosity testing device includes a base 1, a control console 2 fixedly connected to the base 1, a tank 3 fixedly connected to the base 1, a drain valve 4 fixedly connected to the tank 3, and further includes:

[0028] A stirring viscosity measuring mechanism 5 is connected to the base 1. The stirring viscosity measuring mechanism 5 includes a lifting adjustment mechanism 6 fixedly connected to the base 1. The lifting adjustment mechanism 6 is connected to a telescopic rotation mechanism 7. A protective shell 8 is fixedly installed at the end of the telescopic rotation mechanism 7. A first motor 9 is fixedly installed inside the protective shell 8. A rotating disk 10 is fixedly connected to the output shaft of the first motor 9. The rotating disk 10 is rotatably connected to the protective shell 8. A fixed plate 11 is fixedly connected to the rotating disk 10. A resistance sensor 12 is fixedly connected to the fixed plate 11. The resistance sensor 12 is communicatively connected to the control console 2. A scraper 13 is fixedly connected to the lower end of the fixed plate 11. A gap is provided between the scraper 13 and the bottom end of the protective shell 8.

[0029] The degreasing mechanism 14 is connected to the lifting adjustment mechanism 6. The degreasing mechanism 14 includes a variable pitch rotation mechanism 15 connected to the lifting adjustment mechanism 6. The variable pitch rotation mechanism 15 is connected to a multi-directional spray brush mechanism 16.

[0030] The lubricating oil to be tested is placed into the container 3. Then, the lifting and adjusting mechanism 6 drives the telescopic rotation mechanism 7 to descend, allowing the protective shell 8 to enter the lubricating oil. The telescopic rotation mechanism 7 then drives the protective shell 8 to rotate, causing the protective shell 8 to drive the fixed plate 11 to rotate via the rotating disk 10. The fixed plate 11 drives the resistance sensor 12 to rotate. During this process, the lubricating oil applies resistance to the resistance sensor 12, which measures the resistance. The control console 2 records the resistance data and calculates the viscosity of the lubricating oil based on the resistance data measured by the resistance sensor 12. Then, the drain valve 4 discharges the lubricating oil. An external liquid supply device is connected to the multi-directional spray brush mechanism 16 to supply cleaning liquid. The lifting and adjusting mechanism 6 first drives the variable pitch rotation mechanism 15 to rise, which is a variable pitch rotation mechanism. Mechanism 15 drives the multi-directional spray brush mechanism 16 to rotate to provide space. Then, the variable pitch rotation mechanism 15 drives the multi-directional spray brush mechanism 16 to rotate toward the fixed plate 11. The multi-directional spray brush mechanism 16 performs spray brushing operation. The variable pitch rotation mechanism 15 adjusts the position of the multi-directional spray brush mechanism 16 to brush the inner wall of the barrel 3. The telescopic rotation mechanism 7 drives the protective shell 8 to rotate, so that the protective shell 8 drives the fixed plate 11 to rotate through the rotating disk 10. This causes the scraper 13 to scrape the lubricating oil at the bottom of the barrel 3. When the first motor 9 drives the rotating disk 10 to rotate, so that the rotating disk 10 drives the fixed plate 11 to be in a flat state, the moving multi-directional spray brush mechanism 16 performs spray brushing operation on the protective shell 8, the rotating disk 10, the fixed plate 11, the resistance sensor 12, and the scraper 13. This invention uses a combination of a stirring viscosity measuring mechanism 5 and an oil removal mechanism 14 to agitate the lubricating oil and measure the resistance applied to it, thereby measuring the viscosity of the lubricating oil. Then, it automatically performs an oil removal spraying and brushing operation on the lubricating oil, thus achieving automatic measurement and automatic cleaning and improving detection efficiency.

[0031] In one embodiment, the lifting adjustment mechanism 6 includes a first active telescopic frame 17 fixedly connected to the base 1. A suspension 18 is fixedly connected to the movable end of the first active telescopic frame 17. The suspension 18 is connected to the telescopic rotation mechanism 7 and the pitch-changing rotation mechanism 15. The first active telescopic frame 17 drives the suspension 18 to move, thereby adjusting the height of the telescopic rotation mechanism 7 and the pitch-changing rotation mechanism 15.

[0032] In one embodiment, the telescopic rotation mechanism 7 includes a second motor 19 fixedly connected to the suspension 18. The output shaft of the second motor 19 is fixedly connected to a prism 20. The prism 20 is slidably connected to a sleeve rod 21. The sleeve rod 21 is fixedly connected to the protective shell 8. The sleeve rod 21 is fixedly connected to a grooved ring 22. The suspension 18 is fixedly connected to a second active telescopic frame 23. The moving end of the second active telescopic frame 23 is fixedly connected to a lifting frame 24 slidably connected to the suspension 18. The lifting frame 24 is rotatably connected to the grooved ring 22. The second motor 19 drives the prism 20 to rotate, the prism 20 drives the sleeve rod 21 to rotate, the sleeve rod 21 drives the protective shell 8 to rotate, and the sleeve rod 21 drives the grooved ring 22 to rotate, so that the grooved ring 22 and the lifting frame 24 rotate relative to each other. While the second active telescopic frame 23 moves with the suspension 18, it actively drives the lifting frame 24 to move, thereby adjusting the relative position of the sleeve rod 21 and the prism 20, thereby further adjusting the position of the protective shell 8, and thus adjusting the position of the fixing plate 11 and the scraper 13.

[0033] In one embodiment, the variable pitch rotation mechanism 15 includes a third motor 25 fixedly connected to the suspension 18. The output end of the third motor 25 is fixedly connected to a gear 26. The gear 26 meshes with a gear ring 27. The gear ring 27 is fixedly connected to two sets of rotating frames 28. The suspension 18 is fixedly connected to an annular guide rail 29 that is slidably connected to the rotating frames 28. The rotating frames 28 are fixedly connected to a linear track 30. The linear track 30 is fixedly connected to a fourth motor 31. The output shaft of the fourth motor 31 is fixedly connected to a lead screw 32. The lead screw 32 is threadedly connected to a slider 33 that is slidably connected to the linear track 30. The slider 33 is connected to the multi-directional spray brush mechanism 16. The third motor 25 drives the gear 26 to rotate, the gear 26 drives the gear ring 27 to rotate, the gear ring 27 drives the rotating frame 28 to move along the annular guide rail 29, thereby moving the linear track 30. The fourth motor 31 drives the lead screw 32 to rotate, the lead screw 32 drives the slider 33 to move along the linear track 30, thereby moving the multi-directional spray brush mechanism 16.

[0034] In one embodiment, the upper end of the slewing frame 28 is provided with a notch 34, the shape of which is adapted to the shape of the suspension 18. By providing the notch 34 at the upper end of the slewing frame 28, motion interference between the slewing frame 28 and the suspension 18 can be avoided.

[0035] In one embodiment, the multi-directional spray brush mechanism 16 includes a fifth motor 35 fixedly connected to a slider 33. A set of sliders 33 is fixedly connected to a set of fifth motors 35. The output shaft of the fifth motor 35 is fixedly connected to a rotating frame 36.

The two sets of bidirectional nozzles 37 are jointly fixedly connected to a diversion pipe 38. An L-shaped brush layer 39 is fixedly connected to the rotating frame 36. The fifth motor 35 drives the rotating frame 36 to rotate, and the rotating frame 36 drives the bidirectional nozzles 37 to rotate. The bidirectional nozzles 37 spray liquid onto the inner wall of the barrel 3 and the protective shell 8, and then the L-shaped brush layer 39 moves and brushes, thereby enabling the invention to perform self-cleaning operations.
