Description

Technical Field

[0001] This utility model belongs to the technical field of sealing ring corrosion resistance testing instruments, specifically relating to an easy-to-operate cylinder cover sealing ring corrosion resistance testing device. Background Technology

[0002] Sealing rings are generally used as key sealing components between connecting parts and are suitable for cylinder head sealing. When used for cylinder head sealing, sealing rings need to have excellent sealing and corrosion resistance. Therefore, corrosion resistance testing of cylinder head sealing rings is required to simulate their corrosion in various working environments, evaluate the corrosion resistance of the sealing rings, and ensure the seal between the cylinder head and cylinder block connecting parts. There are various types of sealing rings used for cylinder heads. Commonly used rubber sealing rings include neoprene rubber, butyl rubber, and silicone rubber. Commonly used corrosion resistance testing equipment includes corrosion resistance testing chambers. Chinese utility model patent application number CN202221420355.2 discloses a corrosion resistance testing chamber for paint layers. The corrosion resistance testing chamber is a conventional corrosion resistance testing equipment that uses a mixed gas corrosion method. Multiple gases such as oxygen, carbon dioxide, and sulfur dioxide are mixed in a certain proportion. The mixed gas is heated inside the corrosion resistance testing chamber, and the rubber sealing ring component is placed inside the corrosion resistance testing chamber. The rubber sealing ring component is corroded by the flowing mixed gas.

[0003] The principle of testing the rubber sealing rings used in cylinder heads using a corrosion resistance test chamber is based on conventional technology. During testing, it is necessary to test the corrosion resistance of the sealing rings not only in a static state but also in a pressurized working state. When multiple sealing rings are under pressure, the operation is generally manual. However, manually pressing multiple unevenly distributed sealing rings requires adjusting the position of each sealing ring and pressing them one by one, which is a cumbersome process. When testing the corrosion resistance of sealing rings under pressure in a corrosion resistance test chamber, there is a problem with the design of not being able to arrange multiple sealing rings in an orderly manner and press them simultaneously. Therefore, this application proposes a cylinder head sealing ring corrosion resistance testing device that is easy to operate. Utility Model Content

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an easy-to-operate cylinder cover seal ring corrosion resistance testing device, including a corrosion resistance testing chamber 1 and a support frame for orderly arranging cylinder cover seal ring components 7 inside the corrosion resistance testing chamber 1. The surface of the corrosion resistance testing chamber 1 is provided with a door 11, and the inner side wall of the corrosion resistance testing chamber 1 is provided with a support block 12. The support block 12 is combined with the corrosion resistance testing chamber 1 using conventional methods. The support frame includes a support mesh plate 3 that engages with the support block 12, a lifting assembly 4, a shelf 5, and a clamping component 6, which can adjust the support mesh plate... The side of plate 3 is pulled out from inside the support block 12 for easy cleaning of the support mesh plate 3. Four cylinder cover sealing rings 7 are arranged in an orderly manner on the surface of the shelf 5, allowing for simultaneous inspection of the four cylinder cover sealing rings 7. The lifting assembly 4 includes a fixed stud 41 connected to the center of the support mesh plate 3, a lifting screw cylinder 42 spirally sleeved on the outside of the fixed stud 41, a fixed disc 43 installed on the top of the fixed stud 41, a rotating ring 44 rotatably sleeved on the outside of the lifting screw cylinder 42, and connecting rods 45 symmetrically installed on the outer surface of the rotating ring 44. The clamping block 451 connected to the other end of the connecting rod 45, the fixing stud 41, the support mesh plate 3, and the fixing plate 43 are combined using conventional methods. The connecting rod 45, the rotating ring 44, and the clamping block 451 are combined using conventional methods. The lifting screw cylinder 42 rotates and rises and falls vertically along the axis of the fixing stud 41, which facilitates changing the height of the fixing plate 43, the connecting rod 45, the clamping block 451, and the clamping member 6, so that the clamping member 6 squeezes the cylinder cover sealing ring 7, putting it in a squeezed working state. The clamping member 6 includes a connecting rod that passes through the clamping block 451. The unit includes a connecting ring 61 and evenly distributed pressure plates 62. The pressure plates 62 have a "T" shaped structure and press the cylinder cover sealing ring 7 tightly. The placement plate 5 includes a fixing ring 52 and rubber ring placement circular plates 51 evenly distributed on the fixing ring 52. The cylinder cover sealing ring 7 is placed on the surface of the corresponding rubber ring placement circular plates 51. Four cylinder cover sealing rings 7 can be placed in an orderly manner at the same time. The placement plate 5 and the fixing plate 43 are separate structures. The number of placement plates 5 with corresponding rubber ring placement circular plates 51 can be selected according to the number of cylinder cover sealing rings 7 to be tested.

[0025] In this embodiment, the lifting screw cylinder 42 has a "T" shaped cross-section. The outer surface of the bottom end of the lifting screw cylinder 42 is provided with a first annular groove that matches the rotating ring 44. The rotating ring 44 is limited by the lifting screw cylinder 42. The center of the rotating ring 44 and the center of the lifting screw cylinder 42 are on the same axis. The rotating ring 44 moves vertically in the same direction as the lifting screw cylinder 42. The connecting rod 45 has an "L" shaped structure.

[0026] In this embodiment, the clamping block 451 is curved and has an arc groove that mates with the connecting ring 61. The connecting ring 61 is parallel to the fixed plate 43. The clamping block 451 limits the connecting ring 61 and drives the connecting ring 61 to move vertically up and down.

[0027] In this embodiment, the support mesh plate 3 is provided with a vertical limiting rod 31, and the connecting rod 45 is provided with a limiting hole through which the limiting rod 31 passes. The limiting rod 31 passes through the connecting rod 45 to limit the connecting rod 45 and prevent the rotating ring 44 and the connecting rod 45 from tilting when they move upward.

[0028] In this embodiment, the fixing plate 43 includes a fixing cylinder at the center and an outer ring mesh plate. The ring mesh plate is provided with an integral fixing disc 431. The fixing plate 43 is flush with the fixing disc 431. The surface of the fixing disc 431 is provided with a groove that cooperates with the protrusion 511. The protrusion 511 is embedded in the groove, so that the rubber ring placing disc 51 is limited and the placement plate 5 is installed accurately.

[0029] In this embodiment, a recessed storage groove 512 is provided on the surface of the rubber ring placement plate 51. The cylinder cover sealing ring 7 cooperates with the storage groove 512 to limit the cylinder cover sealing ring 7, so that its installation is stable and accurate. A handle 53 is provided on the fixing ring 52. The two ends of the handle 53 are right-angle bent tube structures. A locking stud connected to the fixing ring 52 passes through the end of the handle 53. The handle 53 is firmly connected to the fixing ring 52 through the locking stud, and the storage plate 5 can be moved as a whole.

[0030] In summary, the corrosion resistance testing chamber 1 is designed to orderly place four cylinder cover sealing rings 7 and simultaneously perform pressing operations. Depending on the number of cylinder cover sealing rings 7 to be tested, a corresponding number of rubber ring placement discs 51 can be selected. The lifting screw cylinder 42 rotates and vertically rises and falls along the axis of the fixed stud 41, facilitating changes in the height of the fixed disc 43, connecting rod 45, clamping block 451, and clamping member 6. This allows the clamping member 6 to press the cylinder cover sealing rings 7, placing them in a compressed working state. Simultaneous pressing operations on the cylinder cover sealing rings 7 are possible, making operation convenient.
