Description

Technical Field

[0001] This utility model belongs to the field of lubricant viscosity testing technology, and in particular relates to a device for testing the viscosity of automotive fluid lubricants. Background Technology

[0002] Automotive fluid lubricants are lubricants specifically designed for automobiles. They are substances that reduce wear on mechanical friction parts, cool and seal them. They play a vital role in the automotive industry, effectively sealing the combustion chamber, keeping engine parts clean, and providing rust and corrosion protection.

[0003] Regularly testing the viscosity of lubricants can help detect aging and deterioration of the oil. Tuning fork vibration sensors can be used to test the viscosity of lubricants through immersion. To ensure the position of the sample cup is fixed during the testing process, a viscosity testing device for automotive fluid lubricants was designed. This device uses spring force to clamp and fix the sample cup with two arc-shaped limiting plates, thus fixing the position of the sample cup during the testing process and preventing significant shaking of the sample cup during testing. Utility Model Content

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model pushes the rectangular block to retract into the inner cavity of the rectangular hole by pressing the rectangular head. At this time, under the rebound force of the spring, the cylinder is pushed to slide, and the sample storage cup is clamped and limited by the arc-shaped limiting plate.

[0014] 3. By setting the rubber pad, the inner wall of the arc-shaped limiting plate and the surface of the sample storage cup can be buffered and protected, which can prevent the inner wall of the arc-shaped limiting plate from directly contacting the surface of the sample storage cup and causing damage to the surface of the sample storage cup.

A trapezoidal surface piece 12 is fixedly connected to the opposite side of the two rectangular blocks 8. Two guide grooves are opened in the inner cavity of the rectangular hole. Limiting blocks 13 are welded to the left and right sides of the rectangular block 8. The surface of the limiting block 13 is slidably connected to the inner cavity of the guide groove. By setting the limiting block 13, the sliding direction of the rectangular block 8 can be straight guided during the sliding process of the rectangular block 8 in the inner cavity of the rectangular hole. When the rectangular block 8 rebounds and resets under the action of the small spring 9, it can maintain straight sliding. A round rod 14 is welded to the surface of the circular piece 6. The surface of the round rod 14 is slidably connected to the inner cavity of the hollow support 4.

[0025] Example 2:

[0026] Figure 1-4This invention illustrates an embodiment of a viscosity testing device for automotive fluid lubricants, comprising: a support panel 2 fixedly connected to the surface of a support base 1; lifting brackets 3 fixedly connected to the left and right sides of the support panel 2 by bolts; hollow support members 4 fixedly connected to the tops of the two lifting brackets 3 by bolts; a cylinder 5 slidably connected to the inner cavity of the hollow support member 4; a circular piece 6 fixedly connected to the end of the cylinder 5 opposite to the inner cavity of the hollow support member 4; a spring 7 welded between the circular piece 6 and the inner cavity of the hollow support member 4; a rectangular hole opened on the surface of the cylinder 5; two rectangular blocks 8 slidably connected to the inner cavity of the rectangular hole; a small spring 9 welded between the two rectangular blocks 8; and the front and rear sides of the hollow support member 4... A rectangular frame 10 is connected to each of the cylinders 5 and the circular plate 6. An arc-shaped limiting plate 15 is fixedly connected to the opposite end of the cylinder 5 and the circular plate 6. A rubber pad 16 is fixedly connected to the inner cavity of the arc-shaped limiting plate 15. The rubber pad 16 can provide a buffer between the inner wall of the arc-shaped limiting plate 15 and the surface of the sample storage cup 17, thus preventing the inner wall of the arc-shaped limiting plate 15 from directly contacting the surface of the sample storage cup 17 and causing damage to the surface of the sample storage cup 17.

[0027] Working principle: When using this utility model, the user places the sample storage cup 17 on the top of the support panel 2, and then simultaneously presses the two rectangular heads 11 on both sides, causing the two rectangular heads 11 to push the two rectangular blocks 8 to slide relative to each other and retract into the inner cavity of the rectangular hole. This restricts the position of the cylinder 5 in the inner cavity of the hollow support 4. At this time, under the rebound force of the spring 7, the spring 7 and the disc 6 push the cylinder 5 to slide in the inner cavity of the hollow support 4. The arc-shaped limiting plate 15 clamps and limits the sample storage cup 17, thus fixing the position of the sample storage cup 17 during the testing of the lubricant sample by the tuning fork resonance sensor 19, so as to avoid the sample storage cup 17 from shaking significantly during the testing of the tuning fork resonance sensor 19.

[0028] In summary, this automotive fluid lubricant viscosity testing device, by pressing the rectangular head 11 to push the rectangular block 8 to retract into the inner cavity of the rectangular hole, at this time, under the rebound force of the spring 7, pushes the cylinder 5 to slide, and the arc-shaped limiting plate 15 clamps and limits the sample storage cup 17, thereby achieving the purpose of fixing the position of the sample storage cup 17 during the testing of the lubricant sample by the tuning fork resonance sensor 19, so as to avoid the sample storage cup 17 from shaking significantly during the testing of the tuning fork resonance sensor 19.
