When no weights are placed on the horizontal clamping plate, there is no contact between the friction column and the friction wheel and no friction occurs. After placing weights on the horizontal clamping plate, the friction column and the friction wheel begin to contact and rub, and the anti-wear test begins. The friction force between the friction wheel and the friction column can also be adjusted by placing weights of different weights.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a lubricating oil anti-wear property testing device.

[0025] The utility model provides Figure 1 and 3The lubricating oil anti-wear test device shown includes a box body 1, a first oil tank 2 is fixedly arranged inside the box body 1, a temperature controller 3 is fixedly arranged inside the first oil tank 2, a heating pipe 4 is fixedly connected to the side wall of the temperature controller 3, an oil valve 5 is fixedly arranged on the bottom wall of the first oil tank 2, a first oil pipe 6 is fixedly sleeved inside the oil valve 5, one end of the first oil pipe 6 passes through the bottom wall of the first oil tank 2 and is fixedly connected to the inside of the first oil tank 2, a support plate 7 is fixedly arranged inside the box body 1, a second oil tank 8 is fixedly arranged on the upper surface of the support plate 7, a detection mechanism is arranged inside the second oil tank 8, and the first oil pipe 6 passes through the second oil tank 8 and is connected to the detection mechanism.

[0026] Lubricating oil is placed in the first oil tank 2, and the temperature controller 3 controls the heating tube 4 to heat the lubricating oil to simulate the temperature of the lubricating oil in daily work. When the temperature is reached, the oil valve 5 is opened to allow the lubricating oil to flow in the first oil pipeline 6 to the inside of the detection mechanism.

[0027] In order to detect the anti-wear properties of lubricating oil, such as Figure 1 and 2 As shown, the detection mechanism includes a motor 9, a rotating rod 10, a friction wheel 11, a fixed block 13 and a friction plate 12. The motor 9 is fixedly connected to the outer wall of the box body 1. One end of the rotating rod 10 is fixed to the output end of the motor 9 and is rotatably sleeved with the box body 1. The other end of the rotating rod 10 passes through the side wall of the second oil tank 8 and is fixedly sleeved inside the friction wheel 11. The friction plate 12 is fixedly clamped on the outer wall of the fixed block 13. The first oil pipeline 6 is fixedly sleeved inside the fixed block 13. The friction plate 12 is provided with an opening corresponding to the first oil pipeline 6.

[0028] A connecting rod 14 is fixedly connected to the upper surface of the fixed block 13, and the rod wall of the connecting rod 14 is movably connected to the second oil tank 8. The other end of the connecting rod 14 is fixedly connected to a pressure sensor 15. An electric push rod 16 is fixedly provided on the inner wall of the box body 1, and the output end of the electric push rod 16 is fixedly connected to the upper surface of the pressure sensor 15.

[0029] When the detection mechanism is working, the motor 9 drives the friction wheel 11 to rotate, and the electric push rod 16 drives the friction plate 12 on the fixed block 13 to move slowly downward. The lubricating oil is sprayed from the first oil pipe 6 through the opening on the friction plate 12 and sprayed on the friction wheel 11, so that the space between the friction plate 12 and the friction wheel 11 can be evenly covered with the lubricating oil. When the electric push rod 16 moves slowly downward and the friction wheel 11 rotates and contacts with the friction plate 12, the lubricating oil reduces the friction therein, and the pressure sensor 15 detects the force applied by the electric push rod 16 to the friction wheel 11, thereby detecting the wear resistance of the lubricating oil.

[0030] In order to make the lubricating oil circulation detection, such as Figure 1As shown, an oil pump 17 is fixedly provided on the lower inner wall of the box body 1, and a second oil pipe 18 is fixedly provided at the input end of the oil pump 17. One end of the second oil pipe 18 passes through the support plate 7 and is fixedly connected to the inner wall of the second oil tank 8. A third oil pipe 19 is fixedly provided at the output end of the oil pump 17, and the third oil pipe 19 is fixedly connected to the inner wall of the first oil tank 2.

[0031] When the detection mechanism is working, the lubricating oil will splash in the second oil tank 8, and then enter the second oil pipe 18 after being collected by the second oil tank 8, and then flow into the first oil tank 2 from the third oil pipe 19 through the oil pump 17 under pressure, so that the lubricating oil can be recycled.

[0032] In order to facilitate the replacement and maintenance of the detection device, Figure 2 and 3 As shown, a hinge 20 is fixedly provided on the outer wall of one side of the second oil tank 8, and the other end of the hinge 20 is rotatably connected to a box door 21, and a lock 22 is fixedly provided on the other side of the box door 21, and the other end of the lock 22 is movably sleeved on the outer side of the second oil tank 8.

[0033] When the friction plate 12 needs to be replaced, the box door 21 can be opened through the lock 22 for easy maintenance.

[0034] Finally, in order to facilitate the addition of lubricating oil to the device, such as Figure 1 and 3 As shown, an opening is provided on the box body 1 corresponding to the top of the first oil tank 2 , a cover plate 23 is provided above the opening, and a handle 24 is fixedly provided on the upper surface of the cover plate 23 .

[0035] When the device needs to work, the cover plate 23 is opened to add lubricating oil to the inside of the first box body 1, or the lubricating oil is taken out when the work is finished.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
