Description

Technical Field

[0001] This invention relates to the field of parts manufacturing technology, specifically to an anti-corrosion testing chamber for automotive parts manufacturing. Background Technology

[0002] After production, automotive parts generally need to undergo corrosion resistance testing in an anti-corrosion test chamber to ensure their service life after leaving the factory. During the anti-corrosion test, corrosive liquids (acidic, alkaline, etc.) are sprayed onto the surface of the automotive parts for observation, simulating the corrosion performance of automobiles under different harsh operating environments, thereby determining whether the anti-corrosion performance of the parts meets the production standards.

[0003] Patent application publication number CN216816407U discloses a chemical resistance testing instrument for automotive mechanical parts. Through the setting of a drive device and clamping device, the salt solution can be fully sprayed onto the surface of the automotive mechanical parts, thereby greatly improving the accuracy of the test. The setting of a mixing tank, a storage tank, a first water pump, a second water pump, a mixing device, and a adding tank can make the salt solution recycled, thereby avoiding waste and greatly saving resources.

[0004] Patent application publication number CN220982446U discloses a corrosion-resistant salt spray detection device for mechanical watch parts. By pressing down on the sliding block, two wedge blocks are pressed down under the action of a spring, and the moving block moves to both sides. Then, the parts are picked up and placed at the clamp. The sliding block is then released to release the wedge blocks and the moving block, thus clamping the parts, thereby achieving the effect of conveniently detecting the parts.

[0005] Patent application publication number CN220160311U discloses an anti-corrosion treatment device for processing automotive parts. The anti-corrosion treatment unit is located above the left and middle of the vibrating bed along its length. The drying box is located inside the anti-corrosion treatment box and is located on the right side of the vibrating bed along its length. The vibrating bed passes through the drying box and is connected to the anti-corrosion treatment box. The automotive parts placed on the upper surface of the vibrating bed are flipped as the vibrating bed vibrates. The anti-corrosion treatment unit located above the vibrating bed sprays anti-corrosion liquid onto the automotive parts. The flipped automotive parts ensure that the outer surface of the parts can contact the anti-corrosion liquid, thereby improving the anti-corrosion treatment effect of the automotive parts.

[0006] In the aforementioned patent, the device can improve the anti-corrosion treatment effect of automotive parts. However, the device still has the following problems in actual use: Most existing anti-corrosion testing devices can only complete the single spraying of corrosive liquid. During the spraying process, the nozzle is used to spray the upper or side of the automotive parts, and the angle of the automotive parts is adjusted to achieve multi-directional spraying. However, it is not possible to spray the lower part of the automotive parts. Furthermore, it is difficult to spray multiple automotive parts in all directions at the same time. After the anti-corrosion test is completed, the tested parts need to be manually transferred to a special drying device. If the parts are directly wiped by hand, it will not only increase the number of steps for the staff, but also prolong the overall test time. Moreover, manual operation is easily affected by external factors, and bumps are likely to occur when transferring parts multiple times, which seriously reduces the convenience of the testing device.

[0007] To address the aforementioned issues, there is an urgent need for innovative design based on the existing test chamber structure. Summary of the Invention

[0008] The purpose of this invention is to provide an anti-corrosion testing chamber for automotive parts production, in order to solve the problems mentioned in the background art. The existing anti-corrosion testing devices have limited functions, can only spray corrosive liquid from the top and sides of automotive parts through nozzles, cannot cover the bottom of the parts, are difficult to achieve all-round spraying tests on multiple sets of parts, have poor equipment integration, and require manual transfer of parts to drying equipment after testing. The manual operation steps are cumbersome, the testing is time-consuming, and the parts are easily damaged by bumps and external factors, resulting in poor overall ease of use.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a corrosion testing chamber for automotive parts production, comprising a chamber body and a corrosion chamber formed inside the upper part of the chamber body, with a switch door on the outside of the chamber body, and an infusion pipe and a receiving frame inside the corrosion chamber, while a liquid receiving frame is provided at the lower end of the corrosion chamber; a spraying structure is provided inside the corrosion chamber, which can evenly spray the corrosion testing liquid onto the surface of the automotive parts placed inside the receiving frame; a drying structure is provided inside the chamber body, which can automatically dry the automotive parts placed inside the receiving frame; and an isolation structure is provided inside the corrosion chamber, which is used for sealing and isolating the upper end of the liquid receiving frame.

[0010] Preferably, the spray structure includes a rectangular tube, which is connected to the end of the infusion tube away from the box body, and the micro nozzle inside the rectangular tube is located outside the receiving frame. At the same time, the rectangular tube is slidably connected to the positioning rod inside the corrosion chamber.

[0011] Preferably, the spray structure further includes a working chamber, which is located inside the lower end of the housing. A hydraulic rod and a limiting rod are fixedly installed inside the working chamber. A movable block fixedly installed at the output end of the hydraulic rod is slidably connected to the limiting rod. Traction ropes fixedly installed at both ends of the movable block are fixedly connected to both ends of the rectangular tube.

[0012] Preferably, the lower rack fixedly installed on the outside of the rectangular tube is slidably connected to the inside of the box, and the double gear rotatably installed inside the box meshes with the lower rack. The upper rack slidably installed inside the box meshes with the double gear, and the outside of the adjustable roller rotatably installed on the outside of the upper rack is wound with an infusion tube.

[0013] Preferably, the drying structure includes a drying fan installed on the outside of the chamber, and an electric push rod is provided inside the chamber. The output end of the electric push rod is provided with a lifting plate, and a sealing plate is slidably installed inside the lifting plate.

[0014] Preferably, an adjusting roller is rotatably mounted on the end of the sealing plate away from the drying fan, and the adjusting roller is in close contact with a limiting inclined plate fixedly installed inside the box.

[0015] Preferably, the drying structure further includes air guide plate A and air guide plate B, with air guide plate A rotatably installed inside the corrosion chamber and air guide plate B slidably installed on the side of air guide plate A near the chamber body. A flow guide plate is rotatably installed on the side of air guide plate A and air guide plate B away from the chamber body, and the length of the flow guide plate decreases sequentially from top to bottom in the vertical direction.

[0016] Preferably, a push rod is rotatably mounted on the side of the air guide plate A near the box body, and a lifting block is rotatably mounted on the end of the push rod away from the air guide plate A and slidably connected to the box body. The lifting block is located between the upper moving block and the lower moving block fixedly mounted on the outside of the sealing plate.

[0017] Preferably, the isolation structure includes a flow divider plate, which is disposed at the lower end of the corrosion chamber, and the flow divider plate has flow divider holes equidistantly opened inside the flow divider plate. A movable frame plate slidably installed at the lower end of the flow divider plate is located at the upper end of the liquid receiving frame, and an inclined rod rotatably installed at the upper end of the movable frame plate is rotatably connected to the air guide plate A.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a reciprocating spray structure, allows a rectangular tube to move stably along a positioning rod under the drive of a hydraulic rod and a traction rope. Simultaneously, with the transmission of a lower rack, double gears, and an upper rack, the reserved length of the infusion tube can be automatically adjusted during the spraying process, preventing the infusion tube from being pulled or knotted. This allows the corrosive liquid to be evenly sprayed onto the surface of the components through micro-nozzles, achieving multi-directional full-coverage spraying. This ensures the uniformity of spraying when multiple components are tested simultaneously, solving the problem that traditional devices cannot cover the lower end of components and improving the accuracy of test results.

[0019] 2. This invention features an integrated drying structure. After the anti-corrosion spray test is completed, the lifting plate can be moved by an electric push rod without manual transfer of parts. This simultaneously opens the air intake channel of the sealing plate and pushes the air guide plate A and air guide plate B to unfold synchronously. The airflow generated by the drying fan is evenly guided to each part through the guide plate with gradually changing length. This allows for rapid and automatic drying of the tested parts, reducing manual operation steps, shortening the overall testing time, and avoiding damage to parts caused by manual transfer, thus improving the ease of use of the device.

[0020] 3. The present invention is equipped with a linkage isolation structure. During the unfolding and rotation of the air guide plate A, the moving frame plate will be moved by the tilting rod to realize the automatic sealing and isolation of the lower end of the diversion plate. This can separate the drying airflow from the test waste liquid in the liquid receiving frame, avoid the carry-on of waste liquid moisture during the drying process, improve the drying efficiency, and at the same time, the test waste liquid can be collected in a centralized manner for convenient subsequent unified treatment.

[0021] 4. Furthermore, the diversion plate forms a linkage structure with the air guide plate A through the tilting rod. When the air guide plate A rotates and unfolds for drying operations, it will automatically drive the moving frame plate to slide at the lower end of the diversion plate, completely sealing the diversion hole and preventing the drying airflow from contacting the waste liquid in the liquid receiving frame. This prevents the airflow from carrying water vapor from the waste liquid upwards, ensuring the dryness of the drying airflow and further improving the efficiency of the drying operation. During the spray test, when the air guide plate A retracts, it will reverse and drive the moving frame plate to reset, allowing the diversion hole to be fully exposed. The test waste liquid after spraying can flow evenly into the liquid receiving frame below through the diversion hole, completing the centralized collection of waste liquid. There is no need for additional manual operation to switch the isolation state. The entire process is completed automatically with the operation flow, further improving the automation level of the device.

[0022] 5. Furthermore, the adjustable roller can move synchronously with the upper rack. During the reciprocating spraying process of the rectangular tube, the adjustable roller can simultaneously follow the movement path of the rectangular tube to retract and organize excess infusion tubing, preventing the infusion tubing from accumulating and tangling inside the corrosion chamber. This ensures a smooth and stable spraying process and prevents the movement and spraying operation of the rectangular tube from being affected by the entanglement and pulling of the infusion tubing. This further improves the stability of the spraying structure. At the same time, the adjustable roller can form a stable tension limit on the infusion tubing, preventing the infusion tubing from sagging and interfering with the normal operation of other structures inside the corrosion chamber, thus ensuring the reliability of the overall device operation.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: As Figures 1-4 As shown, the present invention provides the following technical solution: a corrosion test chamber for automobile parts production, including a chamber body 1 and a corrosion chamber 2 opened inside the upper end of the chamber body 1, and a switch door 3 is provided on the outside of the chamber body 1, and an infusion tube 4 and a receiving frame 12 are provided inside the corrosion chamber 2, while a liquid receiving frame 32 is provided at the lower end of the corrosion chamber 2. The corrosion chamber 2 is equipped with a spray structure that can evenly spray the anti-corrosion test liquid onto the surface of the automotive parts placed inside the receiving frame 12. The box 1 is equipped with a drying structure that can automatically dry the automotive parts placed inside the receiving frame 12. The corrosion chamber 2 is equipped with an isolation structure that is used for sealing and isolating the upper end of the liquid receiving frame 32.

[0027] When using this corrosion protection test chamber for automotive parts production, the switch door 3 needs to be opened and the automotive parts to be tested for corrosion protection placed inside the receiving frame 12. Then, the external suction pump can be connected to the infusion tube 4. The external corrosion protection test liquid is delivered to the inside of the infusion tube 4 through the suction pump. The infusion tube 4 is used to deliver the corrosion protection test liquid to the surface of the automotive parts. The receiving frame 32 is used to receive the excess corrosion protection test liquid to prevent leakage of the corrosion protection test liquid.

[0028] like Figures 4-6 and Figure 16As shown, the spray structure includes a rectangular tube 5, and the rectangular tube 5 is connected to the end of the infusion tube 4 away from the box 1. The miniature nozzle 6 inside the rectangular tube 5 is located outside the receiving frame 12. At the same time, the rectangular tube 5 is slidably connected to the positioning rod 11 inside the corrosion chamber 2.

[0029] After the anti-corrosion test fluid is delivered into the rectangular tube 5 through the infusion tube 4, the micro nozzle 6 on the outside of the rectangular tube 5 needs to spray the anti-corrosion test fluid onto the surface of the automotive parts. The micro nozzle 6 directly wraps around the receiving frame 12 in all directions. The movement of the rectangular tube 5 can drive the micro nozzle 6 to move and spray all the surfaces of the multiple automotive parts placed on the upper end of the receiving frame 12, thus achieving the effect of saving costs.

[0030] like Figure 3 and Figure 5 As shown, the spray structure also includes a working chamber 34, which is located inside the lower end of the housing 1. A hydraulic rod 7 and a limiting rod 9 are fixedly installed inside the working chamber 34. Meanwhile, a movable block 8 fixedly installed at the output end of the hydraulic rod 7 is slidably connected to the limiting rod 9. Traction ropes 10 fixedly installed at both ends of the movable block 8 are fixedly connected to both ends of the rectangular tube 5.

[0031] During the extension and retraction of the hydraulic rod 7, it directly pushes the moving block 8 to move outside the limit rod 9. During the movement of the moving block 8, it directly pulls the rectangular tube 5 to slide outside the positioning rod 11 through the traction rope 10, so that the rectangular tube 5 can drive the micro nozzle 6 to move back and forth outside the receiving frame 12.

[0032] like Figures 5-6 and Figure 16 As shown, the lower rack 13 fixedly installed on the outside of the rectangular tube 5 is slidably connected to the inside of the box 1, and the double gear 14 rotatably installed inside the box 1 is meshed with the lower rack 13. The upper rack 15 slidably installed inside the box 1 is meshed with the double gear 14, and the infusion tube 4 is wound around the outside of the adjustable roller 16 rotatably installed on the outside of the upper rack 15.

[0033] During the movement of the rectangular tube 5, the lower rack 13 will be moved directly, and the lower rack 13 will cause the double gear 14 to rotate. The double gear 14 will drive the adjusting roller 16 to move through the upper rack 15. The radius of the gear meshing with the upper rack 15 is twice the radius of the gear meshing with the lower rack 13. This will cause the upper rack 15 to move a distance twice that of the lower rack 13 in the horizontal plane. This allows the adjusting roller 16 to limit the loose infusion tube 4, preventing the infusion tube 4 from falling off too far and affecting the normal operation of the internal structure of the test box, thus realizing the automatic sorting of the infusion tube 4.

[0034] like Figure 4 and Figure 7As shown, the drying structure includes a drying fan 17, which is installed on the outside of the housing 1. An electric push rod 18 is provided inside the housing 1, and a lifting plate 19 is provided at the output end of the electric push rod 18. A sealing plate 20 is slidably installed inside the lifting plate 19.

[0035] During the testing of automotive parts in this test chamber, the chamber 1 needs to be sealed. After a long period of testing, the automotive parts need to be removed and dried to facilitate direct observation of the corrosion status of the parts. At this time, the expansion of the electric push rod 18 can be used to push the lifting plate 19 to drive the sealing plate 20 upward. After the sealing plate 20 moves upward, the drying fan 17 can be activated to dry the automotive parts on the upper part of the receiving frame 12.

[0036] like Figures 7-10 As shown, an adjusting roller 21 is rotatably mounted on the end of the sealing plate 20 away from the drying fan 17, and the adjusting roller 21 is in close contact with the limiting inclined plate 22 fixedly installed inside the box 1.

[0037] During the downward movement of the sealing plate 20, the adjusting roller 21 will roll on the outside of the limiting inclined plate 22 and push the sealing plate 20 to slide on the outside of the lifting plate 19, so that the sealing plate 20 can make close contact with the box 1 and complete the sealing between the box 1 and the outside.

[0038] like Figures 7-10 and Figure 13 As shown, a push rod 25 is rotatably mounted on the side of the air guide plate A23 near the housing 1, and a lifting block 26 is rotatably mounted on the end of the push rod 25 away from the air guide plate A23 and is slidably connected to the housing 1. The lifting block 26 is located between the upper moving block 27 and the lower moving block 28 fixedly mounted on the outside of the sealing plate 20.

[0039] During the up-and-down movement of the sealing plate 20, the lifting block 26 is pushed to slide up and down inside the housing 1 by the upper moving block 27 and the lower moving block 28. When the lifting block 26 slides upward, it will push the air guide plate A23 to rotate through the push rod 25. When the lifting block 26 moves to the uppermost position, it will be supported by the lower moving block 28. At this time, the rotation angle of the air guide plate A23 is greater than 90 degrees, and the air guide plate A23 is in an inclined state. The end of the air guide plate A23 near the sealing plate 20 is higher than the end away from the sealing plate 20, which provides conditions for the sliding of the air guide plate B24 and the rotation of the guide plate 29 at the lower end of the air guide plate B24.

[0040] like Figure 10 and Figure 11As shown, the drying structure also includes air guide plate A23 and air guide plate B24. Air guide plate A23 is rotatably installed inside the corrosion chamber 2, and air guide plate B24 is slidably installed on the side of air guide plate A23 close to the box 1. A flow guide plate 29 is rotatably installed on the side of air guide plate A23 and air guide plate B24 away from the box 1, and the length of the flow guide plate 29 decreases from top to bottom in the vertical direction.

[0041] After the air guide plate A23 completes its rotation, the air guide plate B24 at its upper end will slide on the outside of the air guide plate A23 and move away from the drying fan 17. The guide plate 29 at the lower end of the air guide plate B24 will rotate. At this time, the distance between the air guide plate A23 and the guide plate 29 at the lower end of the air guide plate B24 and the receiving frame 12 decreases from left to right. This can enhance the guiding effect of the airflow blown into the air guide plate A23, so that the blown airflow can flow downward and accelerate the drying of liquid on the surface of the automotive parts.

[0042] like Figure 12 and Figures 14-15 As shown, the isolation structure includes a flow divider plate 30, which is located at the lower end of the corrosion chamber 2. The flow divider plate 30 has flow divider holes 31 equidistantly opened inside. A movable frame plate 35 slidably installed at the lower end of the flow divider plate 30 is located at the upper end of the liquid receiving frame 32. An inclined rod 33 rotatably installed at the upper end of the movable frame plate 35 is rotatably connected to the air guide plate A23.

[0043] During the rotation of the air guide plate A23, the air guide plate A23 will directly push the movable frame plate 35 to slide at the lower end of the diversion plate 30 through the tilting rod 33, thereby sealing the diversion hole 31 by the diversion plate 30, reducing the evaporation of the anti-corrosion test liquid inside the liquid receiving frame 32, and improving the environment.

[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] 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.
