Description

Technical Field

[0001] This utility model belongs to the technical field of spray testing devices, specifically a spray testing device for corrosion testing of vehicle bearings. Background Technology

[0002] The spray testing device for vehicle bearing corrosion resistance is a specialized piece of equipment used to evaluate the corrosion resistance of vehicle bearings. It simulates harsh corrosive environments, such as humidity, salt spray, and chemical corrosion, by spraying a specific liquid onto the bearing surface to test its corrosion resistance. This device is typically equipped with a spray system, test chamber, bearing fixing and rotation system, and control system, allowing for precise control of spray parameters such as liquid concentration, spray time, temperature, and humidity. Its applications are wide-ranging, covering multiple industries including automotive manufacturing, railway transportation, aerospace, and industrial equipment. It is used to test the durability and reliability of vehicle bearings in complex environments, ensuring that the bearings possess sufficient corrosion resistance in actual use, thereby extending their service life and ensuring safe equipment operation. After the existing spray testing equipment sprays the vehicle bearings, a large amount of test liquid remains on their surface. When manually handling the material, the hands and other parts of the body are easily contaminated with this test liquid, which can stain the operator's clothes and skin, causing damage. The slippery liquid may also cause unstable material handling, increasing the difficulty and risk of operation, and making the material handling process extremely inconvenient. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a spray test device for corrosion testing of vehicle bearings. It effectively solves the problem that after the existing spray test device sprays the vehicle bearings, a large amount of test liquid remains on the surface. When manually handling the material, the hands and other parts are easily contaminated with this test liquid, which can cause damage to the operator's clothes and skin.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spray test device for corrosion testing of vehicle bearings, comprising a workbench, a support frame fixedly installed between the two sides of the workbench, a liquid storage tank fixedly installed on the top of the support frame, a spray nozzle fixedly installed at the bottom of the liquid storage tank, a drain platform fixedly installed on the lower front side of the workbench, an opening on the upper front side of the workbench, a baffle plate inside the opening, four placement slots equally spaced on one side of the bottom inside the workbench, an inclined groove on the other side of the bottom inside the workbench, a water drain trough on one side of the bottom inside the inclined groove, a storage cavity inside the bottom of the workbench, a servo motor fixedly installed on one side of the rear side of the workbench via a support plate, a push plate on one side inside the workbench, a transmission assembly at the output end of the servo motor, and the transmission assembly being connected to the push plate and the baffle plate.

[0005] Preferably, slide bars are fixedly installed on both sides of the baffle, and grooves are opened on the inner walls of both sides of the opening. The two slide bars are slidably installed inside the two grooves. A slot is opened at the bottom of the opening, a locking strip is fixedly installed at the bottom of the baffle, and a sealing strip is fixedly installed at the bottom of the slot. The locking strip is inserted into the slot, and the bottom of the locking strip abuts against the sealing strip.

[0006] Preferably, the transmission assembly includes a drive gear, which is fixedly mounted on the output end of the servo motor. The side of the drive gear away from the servo motor is rotatably connected to the worktable via a positioning seat. A driven gear is meshed with the circumferential surface of the drive gear. A shaft is fixedly mounted in the middle of the driven gear. A first bevel gear is fixedly mounted in the middle of the shaft surface. A second bevel gear is meshed with one side of the first bevel gear surface. A rotating shaft is fixedly mounted on one side of the second bevel gear. The surface of the rotating shaft is rotatably connected to the worktable via a bearing. One end of the rotating shaft extends into the interior of the worktable and is fixedly mounted with a threaded rod. A threaded sleeve is threadedly connected to the surface of the threaded rod. One end of the threaded sleeve is fixedly connected to a push plate. Slide rods are movably inserted into both ends of the push plate. Both ends of the two slide rods are fixedly connected to the inner wall of the worktable.

[0007] Preferably, both ends of the shaft are fixedly installed with support arms, and the ends of the two support arms that are away from each other are rotatably connected to the two sides of the worktable through positioning frames. The ends of the two support arms that are away from the positioning frames are provided with transmission grooves, and pins are inserted into the interior of the two transmission grooves. One end of each pin is fixedly connected to a baffle.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the operator places the vehicle bearing inside the placement slot, and then starts the nozzle to spray the test liquid inside the storage tank onto the vehicle bearing, thereby testing the corrosion resistance of the vehicle bearing; the sprayed test liquid will flow into the storage cavity along the inclined groove and the lower water groove for storage; after the test is completed, the operator starts the servo motor to drive the drive gear to rotate, the drive gear drives the shaft to rotate through the driven gear, and the shaft drives the second bevel gear to rotate through the first bevel gear. Since the diameter of the first bevel gear is larger than that of the second bevel gear, the second bevel gear can rotate three times for the first bevel gear to rotate one revolution. When the second bevel gear rotates, it drives the threaded rod to rotate through the rotating shaft. Since the thread pitch of the threaded rod is large, the threaded rod can quickly drive the threaded sleeve to move when it rotates. When the threaded sleeve moves, it drives the push plate to move. When the push plate moves, it slides along the surface of the two sliding rods, thereby increasing the stability of the push plate and the threaded sleeve. When the push plate moves, it pushes the vehicle bearing to move onto the inclined groove and roll downwards. As the shaft rotates, it also drives the two support arms to rotate upward along the two positioning frames. When the two support arms rotate upward, they drive the two pins to move upward through the cooperation of the transmission groove. When the two pins move upward, they drive the baffle to move upward and open. When the baffle moves upward, it can drive the two slide bars to slide along the inside of the two slide grooves, which increases the stability when the baffle moves upward. After the baffle moves upward and opens, the vehicle bearing that rolls downward through the inclined groove can roll directly onto the draining platform for draining, thereby quickly completing the material removal. This allows the vehicle bearing to be quickly and conveniently removed without manual intervention after the spray test, avoiding the contamination of hands and other parts with the test liquid when manually removing materials.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0012] Depend on Figures 1 to 6 The present invention includes a workbench 1, a support frame 2 fixedly installed between the two sides of the workbench 1, a liquid storage tank 3 fixedly installed on the top of the support frame 2, a spray nozzle 4 fixedly installed on the bottom of the liquid storage tank 3, a draining platform 5 fixedly installed on the lower front side of the workbench 1, an opening 9 on the upper front side of the workbench 1, a baffle 6 inside the opening 9, four placement slots 10 evenly spaced on one side of the bottom inside the workbench 1, a sloping groove 11 on the other side of the bottom inside the workbench 1, a drain trough 15 on one side of the bottom inside the sloping groove 11, a storage cavity 16 inside the bottom of the workbench 1, a servo motor 13 fixedly installed on one side of the rear of the workbench 1 via a support plate 12, a push plate 14 inside the workbench 1, a transmission assembly at the output end of the servo motor 13, and the transmission assembly being connected to the push plate 14 and the baffle 6. Sliding strips 7 are fixedly installed on both sides of the baffle 6. Sliding grooves 8 are opened on both sides of the inner wall of the opening 9. The two sliding strips 7 are slidably installed inside the two sliding grooves 8. A slot 18 is opened at the bottom of the opening 9. A retaining strip 17 is fixedly installed at the bottom of the baffle 6. A sealing strip 19 is fixedly installed at the bottom of the slot 18. The retaining strip 17 is inserted into the slot 18, and the bottom of the retaining strip 17 abuts against the sealing strip 19.

[0013] During use, the operator places the vehicle bearing inside the placement slot 10, and then starts the nozzle 4 to spray the test liquid inside the storage tank 3 onto the vehicle bearing, thereby testing the corrosion resistance of the vehicle bearing; the sprayed test liquid will flow into the storage chamber 16 along the inclined groove 11 and the drain trough 15 for storage; after the test is completed, the operator starts the servo motor 13 to drive the transmission component to operate. When the transmission component operates, it drives the push plate 14 to move. When the push plate 14 moves, it pushes the vehicle bearing to move onto the inclined groove 11 and rolls downward. While the transmission component is operating, it also drives the baffle 6 to move upward and open. When the baffle 6 moves upward, it can drive the two slide bars 7 to slide along the inside of the two slide grooves 8, which increases the stability of the baffle 6 when it moves upward. After the baffle 6 moves upward and opens, the vehicle bearing that rolls downward through the inclined groove 11 can roll directly onto the draining platform 5 for draining, thereby quickly completing the material removal. This allows the vehicle bearing to be quickly and conveniently removed without manual intervention after the spray test of the vehicle bearing, avoiding the contamination of hands and other parts with the test liquid when manually removing the material.

[0014] The transmission assembly includes a drive gear 20, which is fixedly mounted on the output end of the servo motor 13. The side of the drive gear 20 away from the servo motor 13 is rotatably connected to the worktable 1 via a positioning seat 22. A driven gear 21 is meshed with the circumferential surface of the drive gear 20. A shaft 23 is fixedly mounted in the middle of the driven gear 21. A first bevel gear 24 is fixedly mounted in the middle of the surface of the shaft 23. A second bevel gear 25 is meshed with one side of the surface of the first bevel gear 24. A rotating shaft 26 is fixedly mounted on one side of the second bevel gear 25. The surface of the rotating shaft 26 is rotatably connected to the worktable 1 via a bearing 27. One end of the rotating shaft 26 extends into the interior of the worktable 1 and is fixedly mounted with a threaded rod 28. A threaded sleeve 29 is threadedly connected to the surface of the threaded rod 28. One end of the threaded sleeve 29 is fixedly connected to a push plate 14. Slide rods 30 are movably inserted into both ends of the push plate 14. Both ends of the two slide rods 30 are fixedly connected to the inner wall of the worktable 1.

[0015] The operator starts the servo motor 13 to drive the drive gear 20 to rotate. The drive gear 20 drives the shaft 23 to rotate through the driven gear 21. The shaft 23 drives the second bevel gear 25 to rotate through the first bevel gear 24. Since the diameter of the first bevel gear 24 is larger than that of the second bevel gear 25, the first bevel gear 24 can rotate the second bevel gear 25 three times for every one rotation of the first bevel gear 24. When the second bevel gear 25 rotates, it drives the threaded rod 28 to rotate through the rotating shaft 26. Since the thread pitch of the threaded rod 28 is large, the threaded rod 28 can quickly drive the threaded sleeve 29 to move when it rotates. When the threaded sleeve 29 moves, it drives the push plate 14 to move. When the push plate 14 moves, it slides along the surface of the two sliding rods 30, thereby increasing the stability of the movement of the push plate 14 and the threaded sleeve 29. When the push plate 14 moves, it pushes the vehicle bearing to move onto the inclined groove 11 and roll downwards.

[0016] Both ends of the shaft 23 are fixedly installed with support arms 31. The ends of the two support arms 31 that are away from each other are rotatably connected to the two sides of the worktable 1 through the positioning frame 32. The ends of the two support arms 31 that are away from the positioning frame 32 are provided with transmission grooves 33. The two transmission grooves 33 are each inserted with pins 34. One end of the two pins 34 is fixedly connected to the baffle 6.

[0017] As the shaft 23 rotates, it also drives the two support arms 31 to rotate upward along the two positioning frames 32. When the two support arms 31 rotate upward, they drive the two pins 34 to move upward through the cooperation of the transmission groove 33. When the two pins 34 move upward, they drive the baffle 6 to move upward and open.
