Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil detection, and particularly relates to a lubricating oil detection device. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. As long as it is applied between two relatively moving objects and can reduce the friction and wear generated due to contact between the two objects, it is lubricating oil.

[0003] Viscosity can represent a basic property of lubricating oil, and the viscosity index indicates the degree of change of the oil viscosity with temperature. The higher the viscosity index, the smaller the influence of the oil viscosity on temperature, and the better its viscosity-temperature performance. Conversely, it is worse. When the existing lubricating oil viscosity detection device is in use, usually the lubricating oil is placed in a storage box, and a rotating shaft is placed in the storage box to rotate, and the viscosity of the lubricating oil is judged by detecting the rotational force. However, it cannot ensure that the lubricating oil can be evenly coated on the outer wall of the rotating shaft, and the detection effect is poor. In view of this, we propose a lubricating oil detection device. Summary of the Utility Model

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] The present utility model will be further described below with reference to the embodiments.

[0036] Embodiment: Refer to the attached Figures 1-5As shown in the figure, a lubricating oil detection device includes a circular ring member 100, with a detection cavity 101 provided in the middle thereof. A cross frame 110 is provided at the upper side position of the circular ring member 100, and a sleeve 120 is fixedly installed in the middle of the cross frame 110; and a moving disk 200 is symmetrically and movably connected to the middle of the detection cavity 101. A connecting frame 210 is fixedly installed on the upper side of the moving disk 200, a driving shaft 220 is fixedly installed in the middle of the connecting frame 210, and a tensile force detector is provided on the driving shaft 220. Specifically, in this application, through the provided circular ring member 100, a detection cavity 101 is opened in the middle thereof. When two moving disks 200 movably connected within the circular ring member 100 move away from each other, the detection cavity 101 at the middle position between the two moving disks 200 is the storage space for the lubricating oil to be actually detected. And it should be noted that during the actual detection process, by adjusting the distance between the two moving disks 200, at this time, the slider 400 fixedly connected to the moving disk 200 will also move synchronously. In this state, the originally grouped material pipes 130 will remain in communication with the detection cavity 101. At this time, a certain amount of lubricating oil can be injected into the detection cavity 101 through the provided material pipes 130, and then the viscosity of the lubricating oil can be detected. It also includes material pipes 130, and the ends of the material pipes 130 are in communication with the chute 102 and are located at the middle position of the chute 102.

[0037] Preferably, in the actual detection process, a chute 102 is opened on the inner wall of the circular ring member 100, and contact pieces 300 are provided on both the upper and lower sides of the inner wall of the chute 102; displacement sensors are provided on the contact pieces 300 at different heights for obtaining the distance parameter between the middle parts of the two moving disks 200 during the detection process. First, use an external driving shaft 220 to adjust the distance between the two moving disks 200 so that there is a gap between the middle parts of the two moving disks 200, so that the lubricating oil to be detected can be injected through the provided material pipes 130. It should be noted that during the actual detection process, there is an interval between the two moving disks 200 at the initial stage. In the subsequent detection process, by continuously adjusting the positions of the moving disks 200 in the direction of moving away from each other, using the tensile force detector provided on the driving shaft 220, the viscosity parameter of the lubricating oil actually located between the middle parts of the two moving disks 200 can be obtained.

[0038] Inside the detection chamber 101, a bladder 150 is provided on the outer wall of the moving disk 200; the inner side of the bladder 150 abuts against the outer wall of the moving disk 200, and the outer side of the bladder 150 is connected to the outer wall of the ring member 100. A connecting pipe 230 is fixedly installed on the moving disk 200. A cavity 201 is formed inside the moving disk 200. An elastic membrane 500 is fixedly connected to the outer wall on one side of the cavity 201. A plurality of circular grooves 501 are formed in a circular structure on the elastic membrane 500. The bladder 150 is kept in communication with the connecting pipe 230 through a flexible pipe 140. Specifically, when the viscosity parameter of the lubricating oil is obtained by using the provided drive shaft 220;

[0039] It should be noted that during this process, when the two moving disks 200 move away from each other, the bladder 150 provided on the outer side of the moving disk 200 will be compressed. Considering the relationship that the provided bladder 150 is kept in communication with the connecting pipe 230 through the flexible pipe 140, and the corresponding connecting pipe 230 is kept in communication with the cavity 201, the gas originally in the bladder 150 will enter the cavity 201. When the viscosity is detected by using the drive shaft 220, the control valve provided on the connecting pipe 230 is in a closed state. When the detection is completed, the control valve will open. At this time, the gas will enter the inside of the cavity 201, causing the provided elastic membrane 500 to expand and squeeze the lubricating oil between the two moving disks 200 to restore it.

[0040] Preferably, in this application, a slider 400 is fixedly installed on the outer wall of the moving disk 200, and the outer wall of the slider 400 is slidably matched with the inner wall of the chute 102; when the moving disks 200 move away from each other, the material pipe 130 is kept in communication with the detection chamber 101. A connecting shaft 240 is fixedly installed on the lower side of the connecting frame 210, and the connecting shaft 240 is located in the middle of the sleeve 120. A torsion spring 600 is provided between the middle of the connecting shaft 240 and the sleeve 120, and a tensile force detector is provided on the torsion spring 600. On the circumferential track of the ring member 100, the length of the slider 400 is less than the length of the chute 102. The above-mentioned use of the provided tensile force detector can obtain the first parameter of the lubricating oil viscosity. In order to improve the accuracy of the lubricating oil viscosity parameter, as mentioned above, the use of the provided elastic membrane 500 can restore the state of the lubricating oil. Subsequently, by rotating the provided moving disk 200, at this time, the slider 400 moves horizontally in the chute 102, and the torsion spring 600 sleeved on the outer wall of the connecting shaft 240 will deform. Through the provided tensile force detector, the viscosity force of the lubricating oil in the rotational mode can be detected again. By comparing the two detected parameter acquisitions, the accurate viscosity parameter of the lubricating oil can be obtained.

[0041] It should be noted that during the subsequent detection process, since the elastic membrane 500 set is in an expanded state and its deformation in the horizontal direction has approached the critical value, it is understood that no deformation will occur, and the parameters obtained by the rotational detection method are more accurate.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
