Description

Technical Field

[0001] This invention relates to the field of sealant testing technology, specifically to a sealant variable environment testing device. Background Technology

[0002] Sealants are functional polymer materials with adhesive and sealing properties. They are key materials for ensuring the sealing of components and extending product life in industrial production and civil engineering projects. Before mass production, it is necessary to test various indicators of sealant.

[0003] In traditional sealant testing equipment, staff place the test specimens, which are fixed with sealant, into various environments for testing and record the test data.

[0004] However, in actual testing, traditional sealant testing devices can mostly only complete a single test requirement. When the test conditions need to be changed, the staff must first stop the current test, remove the test piece from the original device, and then transfer it to another device with corresponding test conditions to re-fix, debug, and start the test. This process is not only cumbersome, but also leads to test interruption, significantly extending the overall test cycle. Furthermore, multiple transfers of test pieces may disrupt the correlation between the data from two consecutive tests, making it impossible to accurately reflect the true performance of the sealant under continuous different conditions, thus posing a risk of data deviation and greatly reducing the reliability of the test results. Summary of the Invention

[0018] In actual testing, traditional sealant testing devices can mostly only complete a single test requirement. When the test conditions need to be changed, the staff must first stop the current test, remove the test piece from the original device, and then transfer it to another device with corresponding test conditions to re-fix, debug, and start the test. This process is not only cumbersome, but also leads to test interruption, significantly extending the overall test cycle. Furthermore, multiple transfers of test pieces may disrupt the correlation between the data from two consecutive tests, making it impossible to accurately reflect the true performance of the sealant under continuous different conditions, thus posing a risk of data deviation and greatly reducing the reliability of the test results.

This variable environment testing device, through the cooperation of a connecting seat, an adjusting seat, a connecting block, a transmission pipe, a transmission rod, and a slide, enables the testing conditions to be changed according to requirements. This allows testers to complete testing requirements under different environments in one device, ensuring the correlation between two consecutive test data and accurately reflecting the true performance of the sealant under continuous different conditions. This not only improves the reliability of the test results but also improves the testing efficiency.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Example 1: By Figure 1-4 It is known that a sealant variable environment testing device includes a base plate 1, a support platform 11 is arranged above the base plate 1, a test chamber 12 is fixedly connected to the top of the support platform 11, a simulation component 13 is inserted into the top of the test chamber 12, and a test piece 2 is arranged inside the test chamber 12. The sealant variable environment testing device also includes a testing mechanism 3, a fixing mechanism 4, and a driving mechanism 5. The testing mechanism 3 is arranged on the side of the test piece 2; the fixing mechanism 4 is arranged on the outer wall of the simulation component 13; and the driving mechanism 5 is arranged below the support platform 11. The test piece 2 is tested by the testing mechanism 3, the simulation component 13 is fixed by the fixing mechanism 4, and the driving mechanism 5 provides driving force to the testing mechanism 3. In the specific implementation process, it is worth noting that the base plate 1 is generally rectangular in shape and can be made of alloy steel. Support legs are installed at all four corners of its bottom. The support platform 11 is also rectangular and made of the same material as the base plate 1. The test chamber 12 is generally cuboid and can be made of stainless steel. Through holes are provided on its side walls, and sealing rings are fixedly connected to the inner walls of these holes. A sealing ring, made of a mixture of polytetrafluoroethylene (PTFE) and rubber, is installed on the inner wall of the sealing ring. A circular through hole is provided on the top of the test chamber 12, and two side openings are provided on both sides of the through hole. The test chamber 12 has a threaded hole and a sealing door on its front. The sealing door is rotatably connected to the outer wall of the test chamber 12 via a hinge. The simulation component 13 is cylindrical in shape, and its specific simulation parameters can be set as needed. The actual effects of different parameters can simulate the environment. For example, the component for simulating temperature can be a Ni200 temperature control heating wire. The Ni200 temperature control heating wire is model ZHONGYA326541, and its main material is pure nickel wire. The heating power range is 1-200W. This heating wire can... To meet the temperature simulation requirements of test chamber 12, and given that pure nickel wire material has good corrosion resistance and stability, the component for simulating humidity can be an AH-15 ultrasonic humidifier or an AH-2 ultrasonic humidifier: power supply is 220V / 50Hz, rated power is 1500W, humidification capacity is 2kg / h, applicable area is 1.5-2㎡, control mode is manual / automatic humidity control, it has the characteristics of automatic atomization humidification, environmental protection and energy saving, humidity can be set arbitrarily, the body is made of stainless steel, and it integrates high-efficiency atomizing plate and anti-fog backflow design, suitable for use in the simulation component 13 of the sealant testing device for humidity simulation. The material and shape of the test piece 2 can be selected according to actual needs, as long as it meets the working requirements. For example, it can be made of round stainless steel, and its outer wall is provided with threaded holes, which can be fixedly connected to the test mechanism 3 by bolts. In actual work, the tester tests the sealant set between the two test pieces 2 through the test mechanism 3, fixes the simulation component 13 through the fixing mechanism 4, and provides driving force to the test mechanism 3 through the driving mechanism 5. Furthermore, two test pieces 2 are provided, and the test mechanism 3 includes a connecting seat 31, an adjusting seat 32, a connecting block 33, a transmission tube 34, a transmission rod 35, and a slide 36. Two connecting seats 31 are provided, each fixedly connected to one side of the outer wall of the two test pieces 2 that is far apart from each other. Two adjusting seats 32 are provided, each sleeved on the outer wall of the two connecting seats 31, and movably connected to both sides of the inner wall of the test chamber 12, extending to the outside of the test chamber 12. Two connecting blocks 33 are provided, each fixedly connected to the outer wall of the two connecting seats 31, and rotatably connected to the inner wall of the two adjusting seats 32 via sealed bearings. Two tubes 34 are provided, which are respectively slidably snapped onto the outer wall of the two connecting seats 31 on the side away from the two test pieces 2, and respectively inserted into the inner wall of the two adjusting seats 32; two transmission rods 35 are provided, which are respectively set on both sides of the outer wall of the test chamber 12, and respectively fixedly connected to the outer wall of the two transmission tubes 34; two sliding grooves 36 are provided, which are respectively opened on the top sides of the base plate 1, and respectively slidably connected to the bottom of the two transmission rods 35; wherein, through the cooperation of the connecting seats 31, adjusting seats 32, connecting blocks 33, transmission tubes 34, transmission rods 35 and sliding grooves 36, the sealant set between the two test pieces 2 is tested; In the specific implementation process, it is worth noting that there are two connecting seats 31, which are made of stainless steel and have an H-shaped cross-section. One end of each seat has a threaded hole for fixing to the test piece 2 with bolts. The outer wall of the other end has two square protrusions, one above the other. There are two adjusting seats 32, which are made of the same material as the connecting seats 31 and have a T-shaped cross-section. They are hollow inside and their outer walls are inserted into the inner wall of the sealing ring. There are two connecting blocks 33, which are made of the same material as the connecting seats 31 and are cylindrical in shape. They have a circular through hole in the center and are fixed to the outer wall of the connecting seats 31. A sealed bearing is fixed and rotatably connected to the inner wall of the adjusting seat 32. Two transmission tubes 34 are provided, made of the same material as the connecting seat 31. A rectangular groove is machined on the outer wall of the end near the connecting seat 31, allowing it to slide and engage with the protrusion at the end of the connecting seat 31. Two transmission rods 35 are provided, made of the same material as the connecting seat 31. Each rod consists of two parts, fixed together by a flange structure and bolts. The lower part has a threaded hole on its side wall, which engages with the drive mechanism 5 to move the transmission rod 35. When it is not necessary to move the adjusting seat 32, the tester... The locking structure between the two parts of the transmission rod 35 can be released. Two grooves 36 are provided, with a cross-section resembling a rectangular recess, used to limit the movement of the transmission rod 35. In actual operation, when testing the sealant between two test pieces 2, the tester activates the drive mechanism 5 via an external controller. The drive mechanism 5 drives the two transmission rods 35 to move simultaneously relative to or in opposite directions. The two transmission rods 35 drive their respective adjusting seats 32 to move, the two adjusting seats 32 drive the two connecting blocks 33 to move, the two connecting blocks 33 drive the two connecting seats 31 to move, and the two connecting seats 31 drive the two test pieces 2 to move, thereby achieving the sealing... The tensile strength test of the sealant is performed simultaneously by the drive mechanism 5, which drives two transmission tubes 34 to rotate, which in turn drives two connecting seats 31 to rotate, which in turn drives two test pieces 2 to rotate, thereby achieving the torsional strength test of the sealant. Therefore, through the cooperation of the connecting seat 31, adjusting seat 32, connecting block 33, transmission tube 34, transmission rod 35 and slide 36, as well as the simulation component 13, multiple tests on the sealant can be performed simultaneously, accurately reflecting the true performance of the sealant under continuous different conditions. This not only improves the reliability of the test results but also improves the test efficiency. Furthermore, the fixing mechanism 4 includes a fixing base 41, a spring 42, a fixing ring 43, a fixing clip 44, and a magnetic component 45. The fixing base 41 is fixedly connected to the inner top of the test chamber 12 and extends to the top of the test chamber 12, and is sleeved on the outer wall of the simulation component 13. The spring 42 is fixedly connected to the bottom of the inner wall of the fixing base 41 and is sleeved on the outer wall of the simulation component 13. The fixing ring 43 is fixedly connected to the outer wall of the simulation component 13. Two fixing clips 44 are provided, which pass through both sides of the outer wall of the fixing base 41 and extend to the inner wall of the fixing ring 43. Multiple magnetic components 45 are provided, which are respectively provided on both sides of the outer wall of the fixing base 41, and the outer side of the outer wall away from the fixing base 41 is fixedly attached to the outer wall of the fixing clip 44. The simulation component 13 is fixed by the cooperation of the fixing base 41, the spring 42, the fixing ring 43, the fixing clip 44, and the magnetic component 45. In the specific implementation process, it is worth noting that the fixing base 41 is generally similar to a quadrangular prism with a cross-section resembling a 'T' shape. Its bottom is fixed to the top of the inner wall of the test chamber 12 by bolts, and its top extends to the outside of the test chamber 12. Its material is the same as that of the test chamber 12. Its side wall is also machined with two circular through holes, and rectangular grooves are machined at the top and bottom of the through holes. A sealing ring is fixedly connected to the bottom of its inner wall. The material of the sealing ring can be high-temperature resistant rubber. The material of the spring 42 can be spring steel, and its elastic coefficient can be selected according to actual needs to meet the working requirements. The fixing ring 43 is generally similar to a circular ring and can be made of engineering plastic. Cylindrical grooves are machined on both sides of its outer wall. Two fixing clips 44 are provided, and their material is ferromagnetic metal. Pull rings are provided on their outer walls for easy pulling by the test personnel. Four magnetic components 45 are provided, located on the inner walls of the four rectangular grooves respectively. Their material can be neodymium iron boron permanent magnets, which can achieve magnetic fixation with the fixing clips 44. In actual operation, when When the simulation component 13 needs to be replaced, the tester holds the top of the simulation component 13 with one hand and pulls a fixing clip 44 with the other hand. Under the pull, the outer wall of the fixing clip 44 moves away from the magnetic component 45, and the end of the fixing clip 44 gradually moves away from the cylindrical groove on the side wall of the fixing ring 43 until it is completely away from the fixing ring 43. The operation of the fixing clip 44 on the other side is the same. After both fixing clips 44 leave the groove on the side wall of the fixing ring 43, the clamping force of the spring 42 disappears and the spring 42 rebounds. At this time, the tester can easily remove the simulation component 13 by cooperating with the rebound force of the spring 42. Finally, the new simulation component 13 is taken out, and the above actions are repeated in reverse to fix the new simulation component 13 to the inner wall of the fixing seat 41 and continue to conduct other tests. Therefore, through the cooperation of the fixing seat 41, spring 42, fixing ring 43, fixing clip 44 and magnetic component 45, the simulation component 13 can be quickly fixed and replaced according to the test requirements, which further improves the reliability of the test results and the test efficiency. Example 2: From Figure 1-4 As can be seen, the drive mechanism 5 includes a servo motor 51, a bevel gear set 52, a drive shaft 53, a pulley 54, and a drive belt 55. The servo motor 51 is fixedly connected to the bottom of the base plate 1, and its output end extends to the top of the base plate 1 through a sealed bearing. The bevel gear set 52 is drivenly connected to the output end of the servo motor 51. There are two drive shafts 53, both of which are drivenly connected to the output end of the servo motor 51 through the bevel gear set 52. There are four pulleys 54, which are fixedly connected to the two ends of the drive shaft 53 and the drive tube 34, respectively. There are two drive belts 55, which are respectively meshed with the outer walls of the two pulleys 54 on the same side. The servo motor 51, bevel gear set 52, drive shaft 53, pulley 54, and drive belt 55 work together to provide driving force to the test mechanism 3. In the specific implementation process, it is worth noting that the model of the servo motor 51 can be selected according to actual needs, as long as it meets the working requirements. For example, it can be the MSME022G1U model. The bevel gear set 52 consists of a first bevel gear and two second bevel gears. The inner wall of the first bevel gear is fixedly connected to the output end of the servo motor 51, and the outer walls of the two second bevel gears are respectively meshed and connected to the two sides of the outer wall of the first bevel gear. The inner walls of the two second bevel gears are respectively fixedly connected to the close ends of the two drive shafts 53. There are two drive shafts 53, which are made of alloy steel and consist of two parts. The two parts are fixed by bolts through a flange structure. One part has external threads on its outer wall, which can be threaded to the drive rod 35. The diameter of the other part is exactly the same as the outer diameter of the drive tube 34. In actual use, when it is not necessary to rotate the test piece 2, the two parts of the drive shaft 53 can be unlocked to achieve a separate pull test on the sealant. There are four pulleys 54, which can be made of aluminum alloy and have rectangular grooves on their outer walls. The material of the drive belt 55 can be polyurethane. The stepper belt has rectangular protrusions machined on its inner wall. Both the stepper belt and the transmission tube 34 can be selected together, for example, the Gates-TP model (5mm tooth pitch). This ensures synchronous transmission without slippage, guaranteeing synchronized operation of the transmission shaft 53 and the transmission tube 34, and preventing uneven force distribution on the test piece 2. In actual operation, when applying torsional force to the sealant between the two test pieces 2, the tester first connects the external power supply to the servo motor 51 via an external controller and starts the servo motor 51. The servo motor 51 drives the bevel gear set 52 to rotate, which in turn drives the two transmission shafts. The two drive shafts 53 rotate in opposite directions, driving their respective pulleys 54 to rotate. These pulleys 54, via a drive belt 55, drive the pulleys 54 located on the outer wall of the drive tube 34 to rotate. Then, the two pulleys 54 drive their respective drive tubes 34 to rotate. The two drive tubes 34, via two connecting seats 31, drive the two test pieces 2 to rotate, thereby applying a torsional force to the sealant between the two test pieces 2. Finally, the tester can record the test data as needed, thus improving the test stability of the sealant variable environment test device. Furthermore, the outer walls of the two drive shafts 53 are rotatably connected to support plates 531 via sealed bearings, and the top and bottom of the two support plates 531 are respectively fixedly connected to the bottom of the support platform 11 and the top of the base plate 1. In the specific implementation process, it is worth noting that there are two support plates 531, which are made of the same material as the base plate 1. A circular through hole is opened in the center of the support plate 531, and a sealed bearing is installed inside the through hole. The support plate 531 provides support force for the support platform 11 and the transmission shaft 53, thereby improving the structural stability of the sealant variable environment testing device. Furthermore, dustproof boxes 551 are fitted onto the outer walls of both transmission belts 55. The bottoms of the two dustproof boxes 551 are fixedly connected to the top sides of the base plate 1, and the outer walls of the two dustproof boxes 551 that are close to each other are rotatably connected to the outer walls of the transmission shaft 53 and the transmission tube 34 through sealed bearings. In the specific implementation process, it is worth noting that there are two dust boxes 551, which can be made of stainless steel. The outer walls of the two dust boxes 551 are fixed with sealing plates on the opposite sides by bolts. In actual work, the pulley 54 and the transmission belt 55 are protected to prevent foreign objects from entering between them and affecting the transmission effect, thereby improving the transmission stability of the sealant variable environment testing device. Furthermore, temperature sensors 14 are provided on both sides of the simulation component 13. Both temperature sensors 14 are fixedly connected to the top of the inner wall of the test chamber 12. Humidity sensors 15 are provided below the two temperature sensors 14. The two humidity sensors 15 are fixedly connected to both sides of the inner wall of the test chamber 12 respectively. In the specific implementation process, it is worth noting that there are two temperature sensors 14, and their models can be selected according to needs to meet the requirements of operation. For example, they can be E8F2-T20C. Temperature sensors 14 are used to monitor the temperature inside the test chamber 12 and provide timely feedback to the simulation component 13. There are two humidity sensors 15, and their models can be selected according to needs to meet the requirements of operation. For example, they can be QFM2160. Humidity sensors 15 are used to monitor the humidity inside the test chamber 12 and provide timely feedback to the simulation component 13. This enables timely recording of the parameters of the sealant during the test and ensures the rigor of the final test data. Working Principle: In actual work, when it is necessary to test the sealant between two test pieces 2, the tester starts the drive mechanism 5 through the external controller. The drive mechanism 5 drives the two transmission rods 35 to move simultaneously relative to each other or in opposite directions. The two transmission rods 35 drive their respective corresponding adjusting seats 32 to move. The two adjusting seats 32 drive the two connecting blocks 33 to move. The two connecting blocks 33 drive the two connecting seats 31 to move. The two connecting seats 31 drive the two test pieces 2 to move, thereby realizing the tensile strength test of the sealant. At the same time, the drive mechanism 5 drives the two transmission tubes 34 to rotate. 34 drives the two connecting seats 31 to rotate, which in turn drives the two test pieces 2 to rotate, thus achieving the torsional strength test of the sealant. In actual work, when it is necessary to replace the simulation component 13, the tester holds the top of the simulation component 13 with one hand and pulls a fixing clip 44 with the other hand. Under the action of the tension, the outer wall of the fixing clip 44 moves away from the magnetic component 45, and the end of the fixing clip 44 gradually moves away from the cylindrical groove on the side wall of the fixing ring 43 until it is completely separated from the fixing ring 43. The operation of the fixing clip 44 on the other side is the same. After the retaining clips 44 on both sides leave the side wall grooves of the retaining ring 43, the clamping force of the spring 42 disappears, and the spring 42 rebounds. At this time, the tester can easily remove the simulation component 13 by cooperating with the rebound force of the spring 42. Finally, the new simulation component 13 is taken out, and the above actions are repeated in reverse to fix the new simulation component 13 to the inner wall of the fixing seat 41 and continue to conduct other tests. In actual work, when it is necessary to apply torsional force to the sealant between two test pieces 2, the tester first connects the external power supply of the servo motor 51 through the external controller and starts the servo motor 51. 1. The servo motor 51 drives the bevel gear set 52 to rotate, which in turn drives the two drive shafts 53 to rotate in opposite directions. The two drive shafts 53 drive their respective pulleys 54 to rotate, which in turn drive the pulleys 54 located on the outer wall of the drive tube 34 to rotate via the drive belt 55. Then, the two pulleys 54 drive their respective drive tubes 34 to rotate, which in turn drive the two test pieces 2 to rotate via the two connecting seats 31, thereby applying a torsional force to the sealant between the two test pieces 2. Finally, the tester records the test data as needed.

[0023] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
