[0002] Grease is a thick, greasy semi-solid used for the friction parts of machinery to play a lubricating and sealing role. It is also used on the metal surface to fill voids and prevent rust, and is mainly prepared from mineral oil (or synthetic lubricating oil) and thickening agent. The fineness of grease is generally used to judge whether the grease contains impurities and whether the combination of oil and soap is complete.

[0003] In the prior art, for example, Chinese Patent CN212083288U discloses a grease dropping point testing device, which includes a detection base, a sealing box and a temperature detection device.

The sealing box includes at least a pair of heat dissipation components, and the heat dissipation components are respectively arranged on the sealing plates on opposite sides of the sealing box.

[0004] However, in the prior art, there is no unified method for testing the fineness of grease at present. Generally, the grease is scraped open with a spatula and observed with the naked eye. However, this method is too subjective and cannot fully characterize the fineness of the grease. Therefore, the present application provides a grease fineness testing structure to meet the requirements. Content of the Utility Model

[0027] Such as Figure 1 - Figure 4As shown in the figure, an embodiment of the present utility model provides a grease fineness test structure, including: a concave plate 3, a screen 1 and a moving frame 5. Both sides of the inner wall of the concave plate 3 are provided with sliding grooves 4. The two sides of the screen 1 are respectively slidably connected to the concave plate 3 through the two sliding grooves 4. Multiple groups of positioning holes 11 are provided at the upper end of the moving frame 5, and injection mechanisms 2 are detachably connected in the multiple groups of positioning holes 11. The injection mechanism 2 includes an empty cylinder 21, a base 24 and a sliding cover 25. A support plate 22 is fixedly connected to the upper end of the empty cylinder 21. A piston 23 is movably installed in the inner wall of the empty cylinder 21. The lower end of the empty cylinder 21 penetrates and is threadedly connected to the upper and lower ends of the base 24. Two groups of strip-shaped grooves 29 are respectively penetrated and provided on both sides of the base 24. Slide shafts 28 are fixedly connected to both sides of the sliding cover 25. The side walls of the two groups of slide shafts 28 are respectively slidably connected inside the two groups of strip-shaped grooves 29. A rubber sleeve 27 is fixedly connected to one side of the sliding cover 25. An L-shaped column 26 is fixedly connected to the outer wall of the empty cylinder 21. When the sliding cover 25 is turned up to a state perpendicular to the base 24, the rubber sleeve 27 is sleeved on the outer wall of the L-shaped column 26. When the sliding cover 25 is closed with the lower end of the base 24, the inner wall of the sliding cover 25 fits with the lower end of the empty cylinder 21, and the lower end of the base 24 fits with the upper end of the screen 1. By pulling the rubber sleeve 27, the sliding cover 25 is driven to slide along the strip-shaped groove 29 to one end position with the slide shafts 28 at both ends, and then the sliding cover 25 is rotated with the slide shafts 28 as the rotation axis, so that the sliding cover 25 forms a 90-degree angle with the base 24, and the rubber sleeve 27 is sleeved on the L-shaped column 26 to fix the position of the sliding cover 25, which is convenient for controlling the outflow of the grease. Then, the piston 23 is quantitatively pressed by observing the scale line, so that the grease flows through the surface of the screen 1. Immediately after the operation is completed, the situation of the sieve surface and sieve holes in the screen 1 is observed. By comparing the amount of grease remaining on the screen 1 by different injection mechanisms 2, the fineness of the grease can be judged, and the fineness degree of the grease can be characterized more accurately. By sliding the screen 1 along the sliding groove 4 on the concave plate 3, the screen 1 with a suitable sieve hole size can be replaced according to the experimental needs, and it is convenient to disassemble, assemble and clean the screen 1.

[0028] As Figure 1 - Figure 4As shown, a limiting groove 7 is formed on one side of the concave plate 3. A limiting block 6 is slidably connected inside the limiting groove 7. One side of the inner wall of the moving frame 5 is fixedly connected to one side of the limiting block 6. The other side of the inner side of the moving frame 5 is rotatably connected to a gear 9. A rack 8 is engaged with the side wall of the gear 9. One side of the rack 8 is fixedly installed on one side of the concave plate 3. The lower end of the moving frame 5 is in contact with the bottom of the rack 8. A rotating handle 10 is fixedly installed at the center of the gear 9. The side wall of the rotating handle 10 movably penetrates through one side of the moving frame 5. The lower end of the support plate 22 is movably clamped at the upper end of the moving frame 5. The size of the sliding cover 25 is adapted to the shape of the base 24. The empty cylinder 21 is made of a transparent material and its outer wall is provided with scale lines. One side of the gear 9 is in contact with the concave plate 3. The length of the limiting groove 7 is equal to the length of the rack 8. Multiple groups of positioning holes 11 are arranged in a straight line, and the distance between adjacent two groups of positioning holes 11 is equal. By rotating the rotating handle 10, the gear 9 is driven to rotate and move along the surface of the rack 8, further driving the limiting block 6 on one side of the lower end of the moving frame 5 to slide along the limiting groove 7. The lower end of the other side of the moving frame 5 slides in contact with the lower end of the rack 8, so that the moving frame 5 moves smoothly, facilitating the replacement of the position of the injection mechanism 2 for multiple experiments for statistical analysis, thereby ensuring the accuracy of the test results of the fineness of the lubricating grease.

[0029] According to the technical solution provided by the present utility model, when testing the fineness of the lubricating grease, first rotate and remove the base 24, pull out the empty cylinder 21 from the positioning hole 11, then separate the support plate 22 from the upper end of the moving frame 5, then inject the lubricating grease into the empty cylinder 21, smooth the lubricating grease at the lower end of the empty cylinder 21, then place the injection mechanism 2 in the positioning hole 11 respectively. By pulling the rubber sleeve 27, the sliding cover 25 is driven to slide along the strip-shaped groove 29 to one end position with the sliding shafts 28 at both ends. Then the sliding cover 25 is flipped with the sliding shafts 28 as the rotation axis, so that the sliding cover 25 forms a 90-degree angle with the base 24, and the rubber sleeve 27 is sleeved on the L-shaped column 26 to fix the position of the sliding cover 25, facilitating the control of the outflow of the lubricating grease. Then, by observing the scale lines, the piston 23 is pressed quantitatively, so that the lubricating grease flows through the surface of the sieve mesh 1. Immediately after the operation is completed, observe the situation of the sieve surface and sieve holes in the sieve mesh 1. By comparing the amount of the lubricating grease remaining on the sieve mesh 1 by different injection mechanisms 2, the fineness of the lubricating grease can be determined, which can more accurately characterize the fineness of the lubricating grease. After completing a group of experiments, by rotating the rotating handle 10, the gear 9 is driven to rotate and move along the surface of the rack 8, further driving the limiting block 6 on one side of the lower end of the moving frame 5 to slide along the limiting groove 7. The lower end of the other side of the moving frame 5 slides in contact with the lower end of the rack 8, so that the moving frame 5 moves smoothly, facilitating the replacement of the position of the injection mechanism 2 for multiple experiments for statistical analysis, thereby ensuring the accuracy of the test results of the fineness of the lubricating grease. By sliding the sieve mesh 1 along the sliding groove 4 on the concave plate 3, the sieve mesh 1 with a suitable sieve hole size can be replaced according to the experimental needs, and it is convenient to disassemble, assemble and clean the sieve mesh 1.
