Description

Technical Field

[0001] This invention belongs to the field of product testing technology, and specifically discloses a rapid clamping type two-dimensional composite motion corrosion and wear testing device and method. Background Technology

[0002] In the field of materials science and engineering, particularly in aerospace, marine engineering, chemical machinery, and biomedical engineering, many critical components often experience the dual effects of corrosive environments and mechanical wear during actual service. This synergistic effect of "corrosion and wear" (i.e., corrosion-wear) typically causes more severe material failure than corrosion or wear alone. Therefore, accurately assessing the service performance of materials under coupled corrosion and wear conditions is of crucial engineering significance for material selection, life prediction, and the development of surface protection technologies.

[0003] Currently, most existing corrosion and wear testing devices have relatively simple structures, making it difficult to realistically simulate complex service conditions. A review of existing testing devices reveals the following common shortcomings: First, the environmental simulation lacks realism. Current equipment typically immerses test samples in a static corrosive liquid during corrosion and wear testing, using a mechanical loading mechanism to bring friction pairs into contact with the sample and generate relative motion. However, in real-world operating conditions (such as fluid transport pipelines, ship propellers, and hydraulic components), corrosive media are often in a flowing state. The scouring effect of the fluid accelerates the stripping of corrosion products and affects the electrochemical behavior at the interface. Existing devices lack effective simulation of the dynamic flow of corrosive media, leading to significant discrepancies between test results and actual conditions.

[0004] Second, wear debris interference is severe during the testing process. In prolonged corrosion and wear tests, wear debris generated on the sample surface due to wear can become suspended or deposited in the corrosive medium. This debris can not only participate in secondary wear, altering the contact state of the friction interface, but also affect the composition and electrochemical properties of the corrosive medium. Existing devices lack a structure for timely extraction and separation of wear debris, making it difficult to ensure the stability of the corrosive medium composition during testing, thus affecting the accuracy and repeatability of the test data.

[0005] Third, the clamping operation is complex and the testing efficiency is low. In existing corrosion and wear testing equipment, the installation and removal of test samples usually require multiple tools and cumbersome steps, which is especially inconvenient when it is necessary to adjust the load or change the sample. At the same time, for tests that require changing the friction trajectory or motion mode, the drive structure of existing devices often has low integration and insufficient motion control precision, making it difficult to achieve stable and controllable two-dimensional composite motion.

[0006] Fourth, the coordination between temperature and electrochemical control is poor. In corrosion and wear testing, temperature is a key parameter affecting the corrosion rate and the mechanical properties of materials. Although some existing devices are equipped with heating functions, they often cannot achieve uniform heating and circulation of the liquid medium, resulting in uneven temperature distribution within the sealed cavity. In addition, electrochemical tests (such as potential and current density measurements) usually require stable electrode arrangements and good sealing performance. Existing equipment has deficiencies in the sealing structure design at the electrode introduction points, making it prone to leakage or the introduction of external interference.

[0007] In summary, developing a corrosion and wear testing device that can realistically simulate the flow of corrosive media, effectively remove wear debris interference, is easy to clamp, and can achieve precise motion control and coupling with multiple environmental parameters is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the purpose of this invention is to provide a rapid clamping type two-dimensional composite motion corrosion and wear testing device and method to solve the problems mentioned above.

[0009] To achieve the above objectives, the present invention provides a rapid clamping type two-dimensional composite motion corrosion and wear testing device, including a bottom shell and a robotic arm that is detachably mounted on the bottom shell. A movable component is provided on one side of the top surface of the bottom shell, and a sealing shell is detachably mounted on the top of the bottom shell. A carrier is slidably mounted inside the sealing shell, and the carrier is used to move the test sample inside the sealing shell. An electrode rod and a friction rod are inserted into the sealed shell. The friction rod passes through the output end of the robot. During operation, a liquid that corrodes the test sample is injected into the inside of the sealed shell. Then, the electrode rod energizes the inside of the sealed shell. The moving part drives the test sample to slide and rub on the friction rod through the carrier. The carrier is equipped with a suction structure for suctioning the abrasive debris separated from the test sample, and simultaneously suctioning the liquid inside the sealed shell to the outside, thereby simulating the flow of liquid inside the sealed shell.

[0010] In the above technical solution, a counterweight ring is fixed to the upper end of the friction rod, the lower part of the friction rod penetrates the sealing shell, and rubber tubes are sleeved on the parts of the electrode rod and the friction rod that penetrate the sealing shell, and the rubber tubes are fixed on the sealing shell.

[0011] In the above technical solution, a heater is further fixed on the bottom shell, the heater includes a pump fixed on the bottom shell, and the output end of the pump is connected to the inner cavity of the sealed shell through a pipe.

[0012] In the above technical solution, a fixing seat is detachably fixed on the bottom shell, and the fixing seat is detachably connected to the lower end of the robot arm. A stop bar is detachably connected to the bottom shell below the sealing shell, and the stop bar is fixed on the sealing shell.

[0013] In the above technical solution, the movable component is further distributed below the sealing shell and located inside the bottom shell. The movable component includes a sliding frame, and a sliding rod passes through the front and rear sides of the sliding frame. The two ends of the sliding rod are fixed inside the bottom shell. A movable seat and a drive structure for driving the sliding frame to move on the sliding rod are fixed on the sliding frame.

[0014] In the above technical solution, a support base is inserted into the movable seat, the support base is detachably connected to the sliding frame, both ends of the slide rod are fixed with limit heads, a connecting spring is fixed on the slide rod between the limit heads and the sliding frame, an electric slide block is fixed on the top surface of the movable seat, and a first magnetic block is fixed at the output end of the electric slide block.

[0015] In the above technical solution, the bottom surface of the movable seat is further provided with a connector, and a screw is threadedly connected to the connector. Both ends of the screw are fixed with rotating rods. The rotating rod at one end of the screw rotates inside the bottom shell, and the rotating rod at the other end of the screw passes through the bottom shell. The rotating rod passing through the bottom shell is sleeved with a mounting plate, and the end of the rotating rod passing through the bottom shell is connected to a drive motor. The fixed end of the drive motor is fixed to the mounting plate, and the mounting plate is fixed to the bottom shell.

[0016] In the above technical solution, the carrier further includes mounting seats distributed inside the sealed shell. A sliding strip slides on the lower part of the mounting seat, a plug-in post is fixed on the top surface of the mounting seat, and a second magnetic block is fixed on the bottom surface of the mounting seat. The side walls of the inner cavity of the sealed shell are provided with directional sliding grooves. The sliding strip slides in the inner cavity of the sealed shell through the directional sliding grooves. A mounting ring abuts against the top surface of the mounting seat. The mounting ring is sleeved on the plug-in post. A platform is inserted into the inside of the mounting ring. A mounting groove is provided on the top surface of the platform. A fixing bolt is threaded onto the mounting ring. The fixing bolt passes through the mounting ring and is connected to the mounting seat.

[0017] In the above technical solution, the suction structure further includes an annular cavity inserted between the stage and the mounting ring, and a suction tube and a connecting handle are detachably fixed on the annular cavity, with the discharge end of the suction tube penetrating the sealing shell.

[0018] A rapid clamping method for testing two-dimensional composite motion corrosion and wear includes the following steps: Step 1, Installation: Place the test sample in the mounting slot, then the robotic arm drives the friction rod through the sealing shell to abut against the test sample. Then, depending on the strength of the test sample, add a number of counterweight rings to the upper part of the friction rod. Step 2, debugging: The heater drives the liquid of the corrosion test sample into the inside of the sealed shell, while ensuring that the liquid submerges the test sample. Then, the liquid is powered through the electrode rod, and the heater heats the liquid inside the sealed shell according to the characteristics of the test sample. Step 3: Test the wear resistance. When the friction rod comes into contact with the test sample, the drive motor can drive the screw to rotate on the connector head, thereby enabling the moving seat to move the first magnetic block along the X direction. The first magnetic block can drive the second magnetic block on the mounting seat to move according to the magnetic attraction force, thereby enabling the test sample on the mounting ring to undergo wear testing on the friction rod along the X direction. Subsequently, the electric slide can drive the first magnetic block to move along the Y direction, thereby enabling the test sample to undergo two-dimensional planar wear testing. Step four: Test corrosion resistance. When the test sample is subjected to the wear test of the friction rod, the suction tube draws liquid from inside the sealed shell, thereby allowing the liquid inside the sealed shell to flow, thus realistically recreating the environment in which the liquid corrodes the test sample.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. This device, by incorporating a suction structure (including an annular cavity and suction pipe) on the carrier, enables real-time suction of wear debris generated during the test sample's wear, while simultaneously driving the corrosive liquid inside the sealed shell to form a directional flow. This design, on the one hand, promptly removes wear debris that may participate in secondary wear, ensuring the stability of the corrosive medium composition; on the other hand, it simulates the scouring effect of fluid on the test sample surface under actual working conditions, making the test environment closer to real service conditions, thereby significantly improving the accuracy and reliability of corrosion wear test data.

[0020] 2. The moving part in this device forms a magnetic attraction between the first magnetic block and the second magnetic block on the carrier, driving the test sample to move stably inside the sealed shell. This magnetic coupling transmission method does not require opening holes in the sealed shell, avoiding the leakage risk caused by the traditional mechanical transmission shaft penetrating the shell. Combined with the rubber tube sleeved at the penetration part of the electrode rod and friction rod, the overall sealing performance of the device is effectively improved, ensuring no leakage of corrosive liquids, while realizing the stable and controllable composite motion of the test sample in the two-dimensional direction.

[0021] 3. This device integrates multiple modules such as heater, pump, electrode rod and counterweight ring, which can simultaneously realize temperature control, circulation flow, electrochemical parameter adjustment and rapid adjustment of friction load of corrosive media. Test samples can be quickly clamped through the mounting slot on the platform. With the detachable sealing shell and bottom shell structure, the sample replacement and device disassembly and assembly process is greatly simplified. This integrated design allows operators to conveniently complete coupled testing of wear resistance and corrosion resistance on the same equipment, reducing experimental preparation time and improving testing efficiency and data comparability.

[0026] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution: The present invention is a rapid clamping type two-dimensional composite motion corrosion and wear testing device, including a bottom shell 6 and a robotic arm 2 detachably mounted on the bottom shell 6. A movable part is provided on one side of the top surface of the bottom shell 6. A sealing shell 3 is detachably mounted on the top of the bottom shell 6. A carrier is slidably mounted inside the sealing shell 3. The carrier is used to move the test sample inside the sealing shell 3. An electrode rod 32 and a friction rod 41 are inserted into the sealed shell 3. The friction rod 41 passes through the output end of the robot arm 2. During operation, the liquid that corrodes the test sample is injected into the sealed shell 3. Then, the electrode rod 32 energizes the inside of the sealed shell 3. The moving part drives the test sample to rub on the friction rod 41 through the carrier. The carrier is equipped with a suction structure for suctioning the wear debris separated from the test sample, and simultaneously suctioning the liquid inside the sealed shell 3 to the outside, thereby simulating the flow of liquid inside the sealed shell 3.

[0027] A counterweight ring 4 is fixed to the upper end of the friction rod 41, and the lower part of the friction rod 41 penetrates the sealing shell 3. Rubber tubes 31 are sleeved on the parts of the electrode rod 32 and the friction rod 41 that penetrate the sealing shell 3. The rubber tubes 31 are fixed on the sealing shell 3 to seal the parts of the electrode rod 32 and the friction rod 41 that penetrate the sealing shell 3.

[0028] A heater 1 is fixed on the bottom shell 6. The heater 1 includes a pump fixed on the bottom shell 6. The output end of the pump is connected to the inner cavity of the sealing shell 3 through a pipe.

[0029] A mounting base 21 is detached and fixed on the bottom shell 6. The mounting base 21 is detached and connected to the lower end of the robot arm 2. A stop bar 7 is detached and connected to the bottom shell 6 below the sealing shell 3. The stop bar 7 is fixed on the sealing shell 3.

[0030] The movable component is located below the sealing shell 3 and inside the bottom shell 6. The movable component includes a sliding frame 77. A slide rod 79 passes through the front and rear sides of the sliding frame 77. Both ends of the slide rod 79 are fixed inside the bottom shell 6. A movable seat 71 and a drive structure for driving the sliding frame 77 to move on the slide rod 79 are fixed on the sliding frame 77.

[0031] A support base 711 is inserted into the movable base 71. The support base 711 is detachably connected to the sliding frame 77. Limit heads 76 are fixed at both ends of the slide rod 79. A connecting spring 78 is fixed on the slide rod 79 between the limit head 76 and the sliding frame 77. An electric slide block 713 is fixed on the top surface of the movable base 71. A slot for installing the electric slide block 713 is opened on the movable base 71. A first magnetic block 72 is fixed at the output end of the electric slide block 713. The electric slide block 713 can drive the first magnetic block 72 to move along the Y direction.

[0032] A connector 712 is fixed to the bottom surface of the movable base 71. A screw 710 is threaded onto the connector 712. Rotating rods 75 are fixed to both ends of the screw 710. The rotating rod 75 at one end of the screw 710 rotates inside the bottom shell 6. The rotating rod 75 at the other end of the screw 710 passes through the bottom shell 6. A mounting plate 74 is sleeved on the rotating rod 75 passing through the bottom shell 6. A drive motor 73 is fixed to the end of the rotating rod 75 passing through the bottom shell 6. The fixed end of the drive motor 73 is fixed on the mounting plate 74. The mounting plate 74 is fixed on the bottom shell 6.

[0033] The carrier includes mounting bases 51 distributed inside the sealed housing 3. A sliding strip 34 slides on the lower part of the mounting base 51. A plug-in post 54 is fixed on the top surface of the mounting base 51. A second magnetic block 58 is fixed on the bottom surface of the mounting base 51. A directional sliding groove 35 is opened on the side wall of the inner cavity of the sealed housing 3. The sliding strip 34 slides in the inner cavity of the sealed housing 3 through the directional sliding groove 35, thereby changing the position of the first magnetic block 72. A mounting ring 5 abuts against the top surface of the mounting base 51. The mounting ring 5 is sleeved on the plug-in post 54. A platform 52 is inserted into the inside of the mounting ring 5. A mounting groove 53 is opened on the top surface of the platform 52. A fixing bolt 55 is threaded on the mounting ring 5. The fixing bolt 55 passes through the mounting ring 5 and is connected to the mounting base 51.

[0034] The suction structure includes an annular cavity 57 inserted between the stage 52 and the mounting ring 5. A suction tube 33 and a connecting handle 56 are detachably fixed on the annular cavity 57. The discharge end of the suction tube 33 passes through the sealing shell 3. The sealing shell 3 is divided into an upper cover and a lower shell. In actual use, the staff can separate the upper cover from the lower shell and then place the carrier in the cavity formed by the upper cover and the lower shell. In actual use, the carrier is first removed from the inside of the sealed shell 3, then the test sample is placed in the mounting groove 53, and then the carrier supporting the test sample is placed inside the sealed shell 3. The pump on the bottom shell 6 can draw the liquid corroding the test sample and deliver it to the inside of the sealed shell 3. When the liquid corroding the test sample is delivered to the inside of the sealed shell 3, the heater 1 can heat the liquid corroding the test sample, so that the test sample is kept at a suitable temperature during the corrosion and wear test. When the liquid inside the sealed shell 3 reaches a suitable temperature, the robotic arm 2 will drive the friction rod 41 to abut against the test sample. Then, according to the hardness of the test sample, an appropriate number of counterweight rings 4 will be added to the upper part of the friction rod 41. The counterweight rings 4 can drive the friction rod 41 to abut against the test sample according to their own weight, which facilitates the subsequent wear test of the test sample on the friction rod 41. When the test sample on the carrier needs to undergo wear testing inside the sealed shell 3, the drive motor 73 drives the screw 710 to rotate. The screw 710 can drive the first magnetic block 72 on the moving seat 71 to move along the X direction through the connector 712. When the moving seat 71 drives the first magnetic block 72 to move along the X direction, the mounting seat 51 can move along the X direction on the sliding bar 34. The first magnetic block 72 can drive the second magnetic block 58 to move along the X direction according to its own magnetic attraction, thereby enabling the second magnetic block 58 to drive the mounting ring 5 on the mounting seat 51 to move along the X direction. This allows the mounting seat 51 to drive the test sample on the stage 52 to rub along the X direction at the end of the friction rod 41. When the test sample needs to undergo wear testing, the electric slide 713 can drive the first magnetic block 72 to move along the Y direction, thereby enabling the test sample to undergo two-dimensional plane wear testing. When the test sample is subjected to wear test inside the sealed shell 3, the electrode rod 32 can supply power to the inside of the sealed shell 3, thereby enabling the electrode rod 32 to supply power to the liquid of the corrosion test sample, which makes it easier for staff to understand the corrosion and wear resistance characteristics of the test sample. When the test sample is rubbed on the friction rod 41, the wear debris detached from the test sample will be distributed in the liquid corroding the test sample. Since there is a suction structure inside the sealing shell 3, when the suction structure inside the sealing shell 3 is working, the discharge end of the suction pipe 33 is connected to the external pump. The external pump can draw the liquid inside the annular cavity 57 through the suction pipe 33, thereby realizing the flow of liquid inside the sealing shell 3, and at the same time, the liquid containing wear debris can be discharged. When the liquid inside the sealed shell 3 is discharged, the liquid of the corrosion test sample inside the sealed shell 3 can flow, thereby realizing the impact of the liquid on the friction parts of the test sample, thus truly restoring the environment of the liquid corrosion test sample.

[0035] Example 2: Please refer to Figures 1-8 As shown, a rapid clamping two-dimensional composite motion corrosion and wear testing method includes the following steps: Step 1, installation: Place the test sample in the mounting slot 53, then the robot arm 2 drives the friction rod 41 through the sealing shell 3 to abut against the test sample. Then, according to the strength of the test sample, add the number of counterweight rings 4 to the upper part of the friction rod 41. Step 2, debugging: The heater 1 drives the liquid of the corrosion test sample into the interior of the sealing shell 3, while ensuring that the liquid submerges the test sample. Then, the liquid is powered through the electrode rod 32, and the heater 1 heats the liquid inside the sealing shell 3 according to the characteristics of the test sample. Step 3: Test the wear resistance. When the friction rod 41 comes into contact with the test sample, the drive motor 73 can drive the screw 710 to rotate on the connector 712, thereby enabling the moving seat 71 to drive the first magnetic block 72 to move along the X direction. The first magnetic block 72 can drive the second magnetic block 58 on the mounting seat 51 to move according to the magnetic attraction force, thereby enabling the test sample on the mounting ring 5 to be worn along the X direction on the friction rod 41. Then the electric slide 713 can drive the first magnetic block 72 to move along the Y direction, so as to perform a two-dimensional plane wear test on the test sample. Step four: Test corrosion resistance. When the test sample is subjected to wear test by friction rod 41, suction tube 33 draws liquid from inside sealing shell 3, which allows the liquid inside sealing shell 3 to flow, thereby truly restoring the environment of liquid corrosion test sample.

Subsequently, the electric slide (713) can drive the first magnetic block (72) to move along the Y direction, thereby enabling the test sample to be tested for two-dimensional plane wear. Step four, test corrosion resistance. When the test sample is subjected to the wear test of the friction rod (41), the suction tube (33) draws the liquid inside the sealing shell (3), thereby allowing the liquid inside the sealing shell (3) to flow, thus truly restoring the environment of the liquid corrosion test sample.
