It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0026] A low-viscosity lubricating oil friction and wear testing device provided by some embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] Combination Figure 1-4As shown, the utility model provides a low-viscosity lubricating oil friction and wear testing device, including a testing module 100 and a replacement module 200, wherein the testing module 100 includes a testing chamber 110, a basic plate 120 movably installed inside the testing chamber 110, a column 130 and two structural frames 140 fixedly connected to the top of the basic plate 120, a liquid inlet pipe 150 connected between the column 130 and the structural frame 140, a shunt pipe 160 connected between the structural frame 140 and the liquid inlet pipe 150, a first friction block 170 interference-plugged with the structural frame 140, a partition 180 fixedly connected to the inside of the testing chamber 110, a cylinder 190 transversely penetrating the partition 180, and a second friction block 191 detachably connected to the cylinder 190, wherein the column 130 movably penetrates the top of the testing chamber 110, and the shunt pipe 160 is sleeved on the outside of the first friction block 170;

[0029] The replacement module 200 includes a plurality of guide strips 210 enclosed on the outside of the basic disk 120, an annular disk 220 slidably sleeved on the outside of the basic disk 120, two limit blocks 230 installed on both sides of the annular disk 220, and a plurality of rods 240 enclosed on the top of the column 130. Two notches are provided at the bottom of the inner cavity of the test chamber 110.

[0030] Furthermore, the two structural frames 140 are vertically symmetrical about the column 130 , and the second friction block 191 is laterally coaxial with the structural frame 140 . With this layout design, the second friction block 191 can be smoothly inserted into the first friction block 170 .

[0031] Furthermore, the top and bottom ends of the guide bar 210 are flush with the top and bottom of the basic plate 120 respectively, and the guide bar 210 is slidably embedded in the inner side of the annular plate 220. With this structural design, the rotation of the basic plate 120 can rotate the annular plate 220, and then the limit block 230 can enter the slot, ensuring that the feeling of obstruction when the structural frame 140 leaves the slot can be transmitted to the staff.

[0032] Furthermore, the thickness of the limit block 230 is greater than the thickness of the annular disk 220, and the top of the limit block 230 is flush with the top of the annular disk 220. The limit block 230 is movably connected to the slot. With this size design, the limit block 230 can be engaged with the slot when it moves to the top of the slot, thereby providing conditions for transmitting the signal of the basic disk 120 rotating 180°.

[0033] Furthermore, the front and rear side walls of the notch are both configured as arc surfaces. This shape design prevents the limit block 230 from getting stuck in the notch, thereby ensuring that the first friction block 170 can be replaced smoothly.

[0034] Embodiment 2:

[0035] Combination Figure 1 and Figure 4 As shown, on the basis of Example 1, the column 130 is vertically coaxial with the center of the basic disk 120, and an I-shaped disk is sleeved on the top of the column 130. The I-shaped disk moves through the top of the test chamber 110. The I-shaped disk can seal the periphery of the column 130 and improve the aesthetics of the device.

[0036] Embodiment three:

[0037] Combination Figure 1 , 2 and Figure 4 As shown, in the above embodiment, the front opening of the test chamber 110 is provided with a window, and the window is located on the front side of the basic plate 120 . A window 300 is installed inside the window, and the window 300 is provided to facilitate the staff to observe the situation inside the test chamber 110 .

[0038] The working principle and use process of the utility model are as follows: when the device is put into actual use, the staff adds lubricating oil into a liquid inlet pipe 150, the lubricating oil flows through the shunt pipe 160, and then enters the periphery of the first friction block 170, the lubricating oil penetrates into the first friction block 170, and then the cylinder 190 is started, the movable end of the cylinder 190 moves with the second friction block 191, and the second friction block 191 is reciprocatedly inserted into the first friction block 170, and then after a period of time, the window 300 is opened, and then the first friction block 170 is removed for observation, and the wear resistance of the lubricating oil can be known. Yes, and then when testing the next lubricating oil, the staff replaces the new second friction block 191 on the movable end of the cylinder 190, and then manually rotates the rod body 240 to rotate the basic disk 120. During the rotation, the limit block 230 passes through the slot and will drop significantly. The staff can judge whether the basic disk 120 has rotated 180° by the feel of the rotating column 130, and then when the unused first friction block 170 moves to the second friction block 191, the cylinder 190 is started, and then the lubricating oil is poured in as described above, which effectively improves the accuracy of the test results.
