Description

Technical Field

[0001] The present invention relates to the technical field of sealing detection, and in particular to a sealing detection test device and a test method based on sealing component processing. Background Art

[0002] Seals are materials or parts used to prevent fluids or solid particles from leaking from adjacent joint surfaces and to prevent foreign matter such as dust and moisture from invading parts inside machinery and equipment. Among them, sealing rings are one of the most commonly used seals.

[0003] During the production process of sealing rings, a certain number of sealing rings need to be randomly selected for sealing testing to evaluate the quality of the entire batch of products. This method can ensure product quality to a certain extent while reducing testing costs and time costs.

[0004] A rubber sealing ring sealing test device disclosed in the patent application with reference publication number CN213422537U is characterized in that the rubber sealing ring to be tested is sleeved on the surface of the sleeve column, and then the sleeve ring is sleeved on the surface of the rubber sealing ring. The liquid is transported to the upper surface of the rubber sealing ring through the cooperation of the water inlet pipe and the nozzle. The operator can intuitively understand the sealing performance of the rubber sealing ring by observing whether the liquid flows under the rubber sealing ring. If the liquid flows under the rubber sealing ring, there are holes on the surface of the rubber sealing ring and the sealing performance of the rubber sealing ring is poor. Otherwise, the sealing performance of the rubber sealing ring is good.

[0005] A comprehensive analysis of the above patents reveals the following defects:

[0006] The above patent application determines whether the sealing performance of the sealing ring is good by observing whether the liquid is leaking. However, when the liquid leaks slightly and there is no obvious flow mark, the naked eye cannot directly observe the leakage of the liquid, which can easily lead to misjudgment of the sealing performance of the sealing ring, and then lead to the lack of credibility of the quality assessment data of the entire batch of products, and the inability to guarantee product quality; and the test liquid will adhere to the surface of the sealing ring, causing contamination to the sealing ring, which needs to be cleaned after the test, resulting in cumbersome testing steps;

[0007] Secondly, each detection process can only detect a single sealing ring, resulting in low detection efficiency and is not suitable for batch detection of sealing rings.

[0008] Therefore, the present invention proposes a sealing property inspection test device and a test method based on sealing component processing to solve the above problems. Summary of the invention

[0009] In view of the deficiencies in the prior art, the present invention provides a sealing property inspection test device and a testing method based on seal processing, which solves the problem that in the current rubber ring seal detection device, when there is a slight leakage of liquid and no obvious flow marks, the liquid leakage cannot be visually observed by the naked eye, which easily leads to misjudgment of the sealing quality of the seal, thereby resulting in a lack of credibility of the quality assessment data of the entire batch of products and an inability to guarantee product quality; and the detection liquid will adhere to the surface of the seal and contaminate the seal, which needs to be cleaned after the detection, resulting in cumbersome detection steps; each detection process can only detect a single seal, resulting in low detection efficiency and the problem of being unable to apply to batch detection of seals.

[0029] The present invention provides a sealing property inspection test device and test method based on sealing component processing. Compared with the prior art, it has the following beneficial effects:

[0030] 1.

If the purple litmus solution turns red, the sealing performance of the rubber sealing ring does not meet the requirements and is a defective product. Otherwise, the rubber sealing ring is a good product. While observing the color change of the color developing component, the sealing performance of the rubber sealing ring can also be determined by observing whether bubbles are generated in the solution in the color developing component. Judging the sealing performance of the rubber sealing ring by these two phenomena can more intuitively and clearly reflect the quality of the sealing performance of the rubber sealing ring, thereby avoiding misjudgment of the sealing test results and ensuring the accuracy of the test results.

A sealing property inspection test device and test method based on seal processing, wherein the test carrier composed of a lifting plate and an isolation ring in the lifting assembly and the sealing cover are of split design, and the annular clamping block and the lifting plate in the clamping assembly are also of split design. The test carrier and the annular clamping block of matching size can be replaced simultaneously according to the size of the rubber sealing ring to be tested, so that the test carrier and the annular clamping block can jointly form a test component suitable for rubber sealing rings of new sizes, thereby achieving the purpose of adapting to the sealing property test of rubber sealing rings of different sizes, and the practicality is significantly improved.

[0033] 4. A sealing property inspection test device and test method based on seal processing, which can accelerate the decomposition rate of carbonic acid in the purple litmus solution in the color developing tube by heating the color developing tube, so that the purple litmus solution can restore its original color in a short time after achieving the purpose of detecting bad rubber ring seals, thereby facilitating the next rubber ring sealing inspection work, and there is no need to frequently replace the purple litmus solution in the color developing component, which not only avoids the waste of raw materials, but also can speed up the inspection speed of rubber ring seals.

Before testing the sealing performance of the rubber sealing ring, the test carrier of the corresponding size is replaced according to the inner and outer diameters of the rubber sealing ring to be tested, and the inner diameter of the isolation ring 338 is required to match the outer diameter of the rubber sealing ring, and the inner diameter of the lifting plate 337 is required to match the inner diameter of the rubber sealing ring; the lifting plate 337 and the isolation ring 338 together constitute a test carrier for carrying the rubber sealing ring. There are multiple groups of test carriers, and the size design of the multiple groups of test carriers is based on several rubber ring seals that are often tested in actual production, and each test carrier is marked with the size of the rubber ring seal that can be tested. The thickness of the lifting plate 337 and the height of the isolation ring 338 in each group of test carriers are kept the same. Therefore, the corresponding test carrier can be quickly found according to the size of the rubber ring seal to be tested, and the original test carrier can be disassembled and replaced, and then the annular clamping block 328 matching the test carrier can be replaced accordingly. The annular clamping block 328 can just slide along the inner wall of the isolation ring 338 to be inserted to a position 1mm away from the top of the lifting plate 337, that is, the annular clamping block 328 is only changed in the inner and outer diameters, and the height remains unchanged;

[0067] After the test carrier that meets the test requirements is replaced, two staff members are required to be located at the front and rear sides of the test platform 1, that is, opposite to the front and rear operating ports of the protective cover; there are four sealing detection mechanisms 3, and the four sealing detection mechanisms 3 are divided into two groups. The two groups of sealing detection mechanisms 3 are symmetrically arranged at the front and rear sides of the turntable 2 with the dividing line of the test platform 1 in the left and right directions as the symmetry axis. The staff can replace the test carrier or take and place the rubber sealing ring seals on the two groups of sealing detection mechanisms 3 through the operating ports at the front and rear positions of the protective cover;

[0068] The staff uses the operation ports on both sides of the protective cover to place the rubber sealing rings to be tested on the top of the lifting plates 337 in the multiple sealing detection mechanisms 3 in sequence, and the rubber sealing rings just completely cover the top of the lifting plates 337;

[0069] Step 2, start the servo motor to drive the turntable 2 to rotate counterclockwise to the first preset angle value, and the sealing detection mechanism 3, driven by the driving block component 1 7, seals the rubber sealing ring to be tested in the cavity inside it, and then the servo motor is intermittent for a preset time of one, and then the air supply component 6 simultaneously delivers a preset amount of carbon dioxide gas to multiple sealing detection mechanisms 3. After the preset time of two, observe the color change in the sealing detection mechanism 3. If there is no obvious color change and no obvious bubbles are generated, the sealing of the rubber sealing ring is good, otherwise, the rubber sealing ring is a defective product; the specific process is: since the servo motor has been programmed, its rotation direction and intermittent time will be carried out according to the preset program;

[0070] After the servo motor is started, it first rotates counterclockwise to a first preset angle value of twenty degrees, and the guide block 235 in the driving block assembly 23 slides from the connection position of the horizontal support surface 1 72 and the inclined surface 74 to the surface of the horizontal support surface 1 72 away from the inclined surface 74, while the guide block 1324 in the clamping assembly 32 gradually climbs from the connection position of the horizontal support surface 1 72 and the inclined surface 74 along the inclined surface 74 to the middle position of the top of the horizontal support surface 2 73. At this time, the guide block 235 in the driving block assembly 23 slides to the middle position of the horizontal support surface 1 72, and the circular The clamping block 328 is inserted into the spacer plate 337 by sliding along the inner wall of the isolating ring 338 to a position 1 mm away from the top of the lifting plate 337. The thickness of the rubber seal is slightly greater than 1 mm. The annular clamping block 328 is pressed on the top of the rubber seal to be tested. The rubber seal to be tested undergoes elastic deformation under the joint action of the annular clamping block 328 and the lifting plate 337, that is, the thickness is compressed, ensuring that the rubber seal to be tested completely seals the connection space between the lifting plate 337 and the annular clamping block 328. When the connection space between the blocks 328 is completely sealed, the leaking gas isolation cover 326 is pressed against the top of the sealing seat 332, and the two are sealed and connected by a sealing strip. At the same time, the gas valve touch switch 3210 and the top of the baffle 339 are pressed against each other, and the gas valve touch switch 3210 is pushed upward, thereby triggering the gas valve 329 to open the gas transmission channel. At the same time, the bottom end of the lifting column 3276 passes through the middle hollow area of ​​the lifting plate 337 and presses against the top of the lifting plate 333. The lifting plate 333 pushes the lifting column 3276 to move upward to the extreme. When the air is in the limited position, the air branch hole 3275 at each position is connected to the branch pipe 3272 at the corresponding position, and the carbon dioxide gas in the carbon dioxide storage tank 61 is transported to the cylinder 3271 through the air inlet nozzle on the top of the sealing cover 321, and enters into the multiple branch pipes 3272 through the main air hole 3274 and the air branch hole 3275, so that the carbon dioxide gas is concentrated in the space between the sealing cover 321 and the lifting plate 333 until the gas pressure of the carbon dioxide in the space is consistent with the gas pressure in the carbon dioxide storage tank 61;

[0071] At this time, the space between the sealing cover 321 and the lifting plate 333 is sealed and covered in the space between the leaking gas isolation cover 326 and the sealing seat 332. If there are holes or damages in the rubber sealing ring seal, the carbon dioxide gas between the sealing cover 321 and the lifting plate 333 will enter the space between the leaking gas isolation cover 326 and the sealing seat 332 through the holes and the damaged area, and then enter the inside of the color developing tube 343 through the air inlet pipe 344. After the carbon dioxide gas enters the inside of the color developing tube 343, it reacts chemically with the water inside the purple litmus to form carbonic acid, and the carbonic acid turns the purple litmus solution red. After an interval preset time of ten seconds, the color change of the purple litmus solution and the churning of bubbles can be observed through the transparent glass observation window 346, and it is judged that the sealing performance of the rubber sealing ring is unqualified and is a defective product. On the contrary, if the purple litmus solution does not change color and no bubbles are generated in the color developing tube 343, the rubber sealing ring is qualified and is a good product.

[0072] Step 3, after the sealing test is completed, the servo motor drives the turntable 2 to rotate the first preset angle value in the clockwise direction, and continues to rotate the second preset angle value after the sealing detection mechanism 3 returns to its original position, and then the sealing detection mechanism 3 is driven by the driving block assembly 2 8 for an intermittent preset time of three, and the rubber sealing ring that has been tested inside it is ejected. At this time, the staff can take out the rubber sealing ring. After the intermittent preset time of three is over, the servo motor drives the sealing detection mechanism 3 to return to its original position again, and performs a sealing test on other rubber sealing rings;

[0073] The specific process is as follows: after the sealing test is completed, the servo motor rotates clockwise to a first preset angle value, and each sealing detection mechanism 3 returns to its original position state, and then continues to rotate clockwise to a second preset angle value of twenty degrees. During the rotation process, the guide block 2 335 climbs along the inclined surface 74 in the driving block assembly 2 8 to the top of the horizontal support surface 2 73. During this process, the guide block 2 335 is pushed upward until the top of the lifting plate 333 is flush with the top of the cylinder 2 331, and then the servo motor enters a five-second intermittent preset time three, and the staff can remove the rubber sealing ring seal after the test. After the intermittent preset time three ends, the servo motor drives the sealing detection mechanism 3 to restore the original position again; after detecting a bad rubber sealing ring seal, the heater 341 can be turned on, and the heating plate in the heating tank 342 heats the color developing cylinder 343. After the purple litmus solution is heated, the carbonic acid inside it is decomposed by heat, and the purple litmus returns to its purple state and can participate in the process of detecting the rubber ring seal again.
