Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating oil performance testing technology, specifically a lubricating oil testing platform. Background Technology
[0002] Viscosity testing is a crucial aspect of lubricating oil inspection, typically performed using a viscometer. The lubricating oil is placed in a graduated cylinder, and its viscosity is measured by agitation using a rotor. Current lubricating oil inspection platforms often employ a clamping plate and a return spring within the cylindrical base to secure graduated cylinders of varying diameters. The clamping plate and return spring work together to hold and position the cylinder. However, in actual use, the repeated extension and contraction of multiple return springs over extended periods can lead to varying degrees of fatigue. This fatigue difference results in an uneven force exerted by each spring on the clamping plate, causing instability in the clamping force on the graduated cylinder.
[0003] As disclosed in the prior art, Chinese utility model publication CN219799130U discloses a lubricating oil testing platform. This utility model uses a hydraulic cylinder mounted on one side of the top of the viscosity meter's support leg. The hydraulic cylinder moves a hydraulic rod up and down, which in turn moves a connecting plate and a cylinder up and down, allowing the lubricating oil in the measuring cylinder to envelop the rotor, eliminating the need for manual adjustment of the rotor height. By installing a squeezing plate and a return spring inside the cylinder, it is easy to fix measuring cylinders of different diameters inside the cylinder. However, in actual use, multiple return springs are prone to varying degrees of fatigue, resulting in the aforementioned problem of unstable clamping of the measuring cylinder. Therefore, we need to propose a lubricating oil testing platform. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 This utility model provides a technical solution:
[0023] The lubricating oil testing platform includes: a base plate 1, on the top of which a support plate 2 is fixedly connected; a viscosity meter 3 is fixedly connected to the top of the support plate 2; and a rotor 4 is installed at the bottom of the viscosity meter 3. By setting up the base plate 1 and the support plate 2, with the support plate 2 made of high-strength alloy material, the two form a stable support frame, providing a solid installation foundation for the viscosity meter 3 and the rotor 4. This ensures that the equipment will not shift or shake due to vibration or other factors during long-term use, thus guaranteeing the overall structural stability.
[0024] The support plate 5 is set above the base plate 1. A measuring cylinder 6 is set on the top of the support plate 5. The central axis of the measuring cylinder 6 is on the same vertical line as the central axis of the rotor 4. A lifting component 7 for adjusting the height of the support plate 5 is set on one side of the support plate 2. The support plate 5 is made of corrosion-resistant stainless steel and the surface is polished. It can stably support measuring cylinders 6 of different specifications. At the same time, the height can be adjusted in conjunction with the lifting component 7. The height position of the measuring cylinder 6 can be flexibly adjusted according to the amount of lubricating oil in the measuring cylinder 6 and the length of the rotor 4 to meet the operational needs of different detection scenarios.
[0025] The positioning seat 8 is fixedly connected to the bottom of the measuring cylinder 6, and two sets of clamping plates 9 are fixedly connected to the top of the support plate 5. The positioning seat 8 is inserted into the inside of the clamping plate 9. The top of the two sets of clamping plates 9 are respectively provided with locking components 10 for quickly positioning the positioning seat 8 and the measuring cylinder 6. By setting the positioning seat 8 and the two sets of clamping plates 9 to be inserted and cooperate, the two side walls of the positioning seat 8 can be tightly fitted with the inner side walls of the clamping plates 9, initially restricting the movement of the measuring cylinder 6 in the horizontal direction. Combined with the locking components 10 for further fixation, it achieves the effect of providing stable initial positioning for the measuring cylinder 6, preventing it from tipping over or shifting during placement and adjustment, and laying the foundation for subsequent accurate fixation.
[0026] The locking assembly 10 includes a U-shaped frame 1001, which is fixedly connected to the top of the clamping plate 9 by bolts. A threaded hole is provided at the center of the top of the U-shaped frame 1001, and a screw 1002 is threaded into the hole. A knob is welded to the top of the screw 1002, and a movable plate 1003 is rotatably connected to its bottom end via a bearing. The movable plate 1003 is horizontally positioned, and its length matches the distance between the two clamping plates 9. Three to four sets of insert rods 1004 are uniformly fixedly connected to the bottom of the movable plate 1003 by welding. The insert rods 1004 are made of hard alloy material, and their bottom ends... The plate 9 is conical in shape and has through holes that correspond one-to-one with the insertion rods 1004. The bottom ends of several sets of insertion rods 1004 pass through the through holes on the plate 9 and are inserted into the interior of the positioning seat 8. By setting up a cooperative structure of screw 1002, movable plate 1003 and insertion rods 1004, when the screw 1002 is rotated, the movable plate 1003 can be driven to move smoothly up and down under the transmission action of the thread, so that the insertion rods 1004 can be inserted into or released from the positioning seat 8. This achieves the effect of quickly completing the locking and unlocking operation of the positioning seat 8 and the measuring cylinder 6 by simply turning the knob. The operation is convenient and the fixing effect is firm.
[0027] It also includes two sets of guide rods 1005, which are located on both sides of the screw 1002 and are symmetrically distributed with the screw 1002. Both sets of guide rods 1005 are slidably inserted into the top of the mortise frame 1001. The mortise frame 1001 has guide holes that are adapted to the guide rods 1005. The inner wall of the guide holes is smooth. The bottom ends of both sets of guide rods 1005 pass through the guide holes on the mortise frame 1001 and are fixedly connected to the top of the movable plate 1003 by welding. By setting the guide rods 1005, the fit clearance between them and the guide holes is controlled at 0.1-0.2mm, which can effectively limit the rotation or offset of the movable plate 1003 during the up and down movement, so as to ensure that the movable plate 1003 always remains in a horizontal state, and that each insertion rod 1004 can be accurately aligned with the insertion position on the positioning seat 8, ensuring a smooth and accurate insertion process.
[0028] The top of the positioning seat 8 has a corresponding insertion hole 11 that matches the insertion rod 1004. The depth of the insertion hole 11 is 2-3cm, and its inner diameter is 0.1mm larger than the outer diameter of the insertion rod 1004. The bottom end of the insertion rod 1004 is inserted into the interior of the insertion hole 11, and the outer wall of the insertion rod 1004 is tightly fitted with the inner wall of the insertion hole 11. By setting the insertion hole 11 that matches the insertion rod 1004, and the inner wall of the insertion hole 11 being hardened to increase wear resistance, the insertion rod 1004 can form a stable fit after insertion, which prevents the insertion rod 1004 from shaking in the insertion hole 11, further enhancing the locking effect on the positioning seat 8 and ensuring that the measuring cylinder 6 will not be displaced during the testing process.
[0029] The lifting assembly 7 includes an electric push rod 701, which is fixedly installed on one side wall of the support plate 2. The telescopic end of the electric push rod 701 is fixedly connected to a lifting plate 702. One end of the lifting plate 702 is fixedly connected to a connecting block 703, and one end of the connecting block 703 is connected to the support plate 5. By setting the electric push rod 701 as a power source, which is driven by a servo motor, precise stroke control can be achieved, driving the lifting plate 702, the connecting block 703 and the support plate 5 to rise and fall synchronously. This achieves the effect of replacing manual adjustment, realizing the automatic adjustment of the height of the support plate 5, and improving the adjustment accuracy and ease of operation.
[0030] The support plate 2 has a through groove 12 that is adapted to the connecting block 703. One end of the connecting block 703 passes through the through groove 12 and is fixedly connected to the support plate 5. By setting the through groove 12, sufficient space is provided for the vertical movement of the connecting block 703.
[0031] A sliding rod 13 is fixedly connected to the top of the base plate 1. The lifting plate 702 is slidably connected to the sliding rod 13. The sliding rod 13 is vertically welded to the top of the base plate 1 near the edge. The sliding rod 13 is made of round steel with a chrome-plated surface. Its height is 10-15cm greater than the maximum extension length of the electric push rod 701. The lifting plate 702 has a sliding hole that matches the sliding rod 13. A linear bearing is installed in the sliding hole. The lifting plate 702 is slidably connected to the sliding rod 13 through the sliding hole. By setting the sliding connection structure between the sliding rod 13 and the lifting plate 702, the linear bearing can effectively reduce the coefficient of friction between the two, making the movement of the lifting plate 702 more stable. This achieves the effect of providing additional support and guidance for the lifting plate 702, preventing the lifting plate 702 from tilting due to uneven force during the lifting process, and ensuring that the support plate 5 is always in a horizontal state.
[0032] Working principle: In use, first align the positioning seat 8 at the bottom of the measuring cylinder 6 containing lubricating oil with the two sets of clamping plates 9 at the top of the support plate 5, insert the positioning seat 8 between the two sets of clamping plates 9, so that the two side walls of the positioning seat 8 are tightly fitted with the inner side walls of the clamping plates 9, completing the initial positioning. Next, rotate the screw 1002 in the locking assembly 10. Under the guidance of the guide rod 1005, the screw 1002 drives the movable plate 1003 to move downward, so that the insertion rod 1004 passes through the through hole on the clamping plate 9 and is precisely inserted into the insertion hole 11 at the top of the positioning seat 8, thus firmly fixing the measuring cylinder 6. Then, start the electric push rod 701. The telescopic end of the electric push rod 701 drives the lifting plate 702 to slide up and down along the slide rod 13. The lifting plate 702 drives the support plate 5 and the measuring cylinder 6 to move up and down synchronously through the connecting block 703 until the lubricating oil in the measuring cylinder 6 just completely covers the rotor 4, and then turn off the electric push rod 701. Finally, start the viscosity meter 3, and the rotor 4 begins to agitate the lubricating oil for viscosity testing. During the testing process, the measuring cylinder 6 is stably fixed and its height is precise, ensuring the accuracy of the test results. After the test is completed, reverse the above steps to remove the measuring cylinder 6, completing one testing cycle.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
