[0002] The drive axle is a key component of vehicle propulsion. Whether the drive axle can work normally not only affects the driving speed, but also whether the car can move. Therefore, the lubrication of the drive axle is also one of the extremely important tasks.

[0003] In actual use, long-term operation of the car will cause the gear oil to heat up. When it comes into contact with air under high temperature, oxidation reaction will occur, producing acidic substances and sediments. Oxidation will cause the viscosity of the gear oil to increase, the color to darken, and even produce odor. Oxidation will also reduce the lubrication and anti-wear properties of the gear oil, resulting in increased friction and wear of the equipment, so the lubricant needs to be tested regularly.

[0004] The existing detection method generally takes out the internal oil and sends it to the detection equipment for detection separately. After the detection, the instrument needs to be cleaned, which is very troublesome. Especially in the test process of testing the performance of the lubricating oil in the drive axle assembly and the compatibility with the drive axle assembly, repeated tests are required to detect the quality changes of the lubricating oil in different strokes and the compatibility of the two.

[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combination Figure 1-3 As shown, a cleanliness quality detection device for an automobile drive axle comprises:

[0025] A base 1, a support column is provided on the top of the base 1, and a mounting plate 11 is arranged horizontally on the top of the support column, and the two form a fixed support structure to position and support other components;

[0026] The spectrum analyzer 3 is arranged between the base 1 and the mounting plate 11 and is used to detect the oil;

[0027] The locking assembly 4 is arranged at the opening of the top surface of the mounting plate 11. The center of the opening is provided with a collection tube 2. The locking assembly 4 is used to lock and fix the collection tube 2 to prevent it from tipping over and causing oil leakage.

[0028] The cleaning component 5 is arranged at one side of the base 1 and is used to flush the inner wall of the collection tube 2 with a cleaning liquid to ensure that the inside of the collection tube 2 is in a clean state each time a test is performed, thereby making the test data more accurate.

[0029] Specifically, the base 1 and the mounting plate 11 are provided with a slide groove 12 on the opposite side, and the top and bottom of the spectrum analyzer 3 are respectively provided with support angles and are slidably inserted into the slide groove 12, so that the entire spectrum analyzer 3 can be slid to the center of the mounting plate 11 and arranged directly below the center, and the structure can be disassembled or assembled at any time, which is very convenient to use.

[0030] A jack is provided on the top of the spectrometer 3 for inserting the object to be measured, and a through hole is provided at the center of the top surface of the mounting plate 11 to be aligned with it vertically, so that the collection tube 2 at the center of the mounting plate 11 can be vertically plugged into the spectrometer 3 to detect the oil contained inside.

[0031] The locking assembly 4 includes a plurality of limit grooves 41 arranged at the through holes on the top surface of the mounting plate 11. The plurality of limit grooves 41 are arranged in a circular array, and the interior of the mounting plate 11 is hollow and provided with an adjustment plate 43. The adjustment plate 43 is an annular structure, and a vortex-shaped groove arranged in a gradually opening manner from the center to the outside is provided on its top surface. A card block 42 is also provided in the limit groove 41, and the bottom of the card block 42 extends downward and is inserted into the groove. Therefore, when the adjustment plate 43 is twisted, all the card blocks 42 can be driven to move toward the center or away from the center, thereby achieving the effect of fixing the collection tube 2. Moreover, under this structure, the collection tube 2 can adopt any size model, which increases the scope of application of the equipment and further improves the use effect.

[0032] Based on the adjustment method of the above structure, the present application should also adopt a driving method with a self-locking structure to fix the adjustment plate 43. The purpose is to avoid the adjustment plate 43 from reversing due to external vibration and other factors, thereby causing the collection tube 2 to loosen. Therefore, a worm gear is also provided at the bottom of the adjustment plate 43, and a worm 44 is arranged horizontally in the mounting plate 11. One end of the worm 44 extends to the outside of the mounting plate 11 and is provided with an adjustment cover 45. The outer wall of the adjustment cover 45 is provided with anti-slip grooves. The transmission method of the worm gear 44 can achieve a self-locking effect, thereby ensuring the stability of the clamping of the collection tube 2, and only reversal is required for disassembly. The structure is simple and easy to use.

[0033] During the clamping process, it is also necessary to prevent cracks from appearing on the side wall of the collection tube 2 due to excessive squeezing pressure, which may eventually lead to damage. Therefore, an elastic pad should be provided on the side of the block 42 facing the center. The elastic pad should be a wavy silicone pad, which is not only soft, but also has a wavy anti-slip structure that can enhance the friction between the two, thereby further improving its stability.

[0034] The collecting tube 2 is a glass tube with a wooden stopper 21, and a hole is opened on the wooden stopper 21 at the top. There are two holes and they are respectively arranged close to the two inner walls of the collecting tube 2. A liquid inlet pipe 22 and a liquid extraction pipe 23 are respectively arranged inside the two holes. The bottom end of the liquid inlet pipe 22 extends inward and is arranged close to the bottom of the collecting tube 2, and the other end of the liquid inlet pipe 22 extends outward and extends to the inside of the drive axle assembly through a hose, and is immersed in the lubricating oil.

[0035] One end of the suction tube 23 is arranged flush with the bottom surface of the wooden plug 21, and the other end is connected to the micro pump 53. Through the extraction of the micro pump 53, a negative pressure is formed inside the collection tube 2, so that the lubricating oil inside the drive axle assembly is extracted by the suction tube 23, realizing the function of automatic collection.

[0036] The cleaning component 5 includes a liquid storage tank 51 disposed on the base 1 and arranged near the spectrometer 3. The liquid storage tank 51 stores a cleaning liquid, which can be alcohol or aviation gasoline, etc. Its purpose is to quickly clean the inner wall of the collection tube 2 by immersion, keep the inner wall of the collection tube 2 clean, and reduce the error of the test result.

[0037] In order to effectively utilize the above-mentioned negative pressure extraction structure, an electric three-way valve 52 should be set on the liquid inlet pipe 22, and the liquid storage tank 51 is connected to one of the interfaces on the electric three-way valve 52 via a pipeline, so that the cleaning liquid can be extracted by simply switching the channel of the three-way valve.

[0038] In addition, in this embodiment, a drain pipe 24 is provided at the bottom of the collection pipe 2, and an electronic valve 25 is arranged at the connection between the drain pipe 24 and the collection pipe 2, so that the oil inside the collection pipe 2 can be discharged by controlling the on-off of the electronic valve 25.

[0039] The above structures are mostly electronic devices. Therefore, a PLC microcontroller can be separately set up on the basis of the entire device, so as to facilitate programming and control of the entire use steps, so that it can be operated automatically, which greatly simplifies the detection steps and makes the operation more convenient.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
