Description

Technical Field

[0001] This utility model belongs to the technical field, specifically relating to an air compressor cylinder cover plate. Background Technology

[0002] The cylinder head plate of an air compressor is a crucial component, primarily responsible for sealing the cylinder to ensure the efficient generation and storage of compressed air. Cylinder head plates are typically made of high-temperature and corrosion-resistant materials such as aluminum alloy or cast iron to withstand high pressure and temperature variations. Their design not only affects the compressor's operating efficiency but also plays a vital role in the stability and safety of the entire system. A well-designed cylinder head plate can effectively reduce gas leakage, improve compression efficiency, and extend the equipment's lifespan.

[0003] In the existing technology, air compressor cylinder cover plates are mostly simple bare plate structures. However, in actual use, bare plate cover plates are prone to deformation or damage under high pressure and high temperature due to their low material rigidity and insufficient strength. In addition, bare plate cover plates have little heat dissipation design, resulting in insufficient heat dissipation capacity, which leads to overheating of the equipment, affects the normal operation of the equipment, reduces the working efficiency and safety of the cylinder cover plate, shortens its service life, and thus affects the normal use of the air compressor cylinder, which has certain limitations. Utility Model Content

[0004] To address the problems of existing air compressor cylinder cover plates being plain plates with low rigidity and insufficient strength, which easily deform under high temperature and high pressure conditions and have insufficient heat dissipation performance, thus affecting the normal use of air compressor cylinders, this utility model provides an air compressor cylinder cover plate.

[0005] The objective of this utility model can be achieved through the following technical solutions: An air compressor cylinder cover includes a cover body; three second reinforcing ribs are arranged sequentially from the center outward on the lower surface of the cover body; four outwardly extending first reinforcing ribs are arranged at the center of the lower surface of the cover body, and the first reinforcing ribs and the second reinforcing ribs are intersected and connected to each other; a third reinforcing rib is arranged near each of the four corners of the cover body, and the third reinforcing ribs are intersected and connected to the second reinforcing ribs; a fourth reinforcing rib is arranged at each of the four edges of the cover body, the fourth reinforcing rib having a U-shaped structure and being interconnected with the third reinforcing ribs to form a closed loop.

[0006] Furthermore, the second reinforcing rib is a concentric ring structure, and the three second reinforcing ribs are distributed at non-uniform intervals.

[0007] Furthermore, the first reinforcing rib and the second reinforcing rib intersect to form a grid-like reinforcing structure, which together divides the cover plate body into multiple small areas.

[0008] Furthermore, the cover plate body is provided with rounded chamfers at the four corner positions.

[0009] Furthermore, a sunken platform is provided at each of the four corners of the cover plate body; the third reinforcing rib is located at the arc edge of the sunken platform.

[0010] Furthermore, the cover plate body has threaded holes at the center of the sunken platform corresponding to the four corners.

[0011] Furthermore, protrusions are provided at the intersections of the first, second, and third reinforcing ribs.

[0012] Furthermore, the thickness of the fourth reinforcing rib is greater than the thickness at the sinking platform.

[0013] The beneficial effects of this utility model are: 1. This utility model employs an innovative composite reinforcing rib structure design consisting of a first reinforcing rib, a second reinforcing rib, a third reinforcing rib, and a fourth reinforcing rib. This design constructs a complete mechanically optimized structure on the cover plate body, improving overall bending stiffness, optimizing natural frequency, and effectively avoiding resonance. Simultaneously, the grid-like layout of multiple reinforcing ribs divides the cover plate into multiple small areas, reducing sound radiation efficiency and lowering noise levels. Furthermore, the intersecting arrangement of multiple reinforcing ribs forms a heat conduction path, optimizing the heat dissipation function of the cover plate body, reducing operating temperature, ensuring normal operation of the compressor cylinder, and extending its service life.

[0014] 2. This utility model has rounded chamfers at the four corners of the cover plate body. The rounded transition effectively alleviates the stress concentration problem caused by the traditional right-angle structure, and provides assembly guidance function, making the installation process more convenient and safe. In addition, the chamfers form good structural continuity with the fourth reinforcing rib and the first reinforcing rib, ensuring the overall rigidity distribution while avoiding local stress peaks, thus improving the reliability, assemblability and service life of the cover plate body.

[0015] 3. The present invention provides protrusions at the intersection of the first and second reinforcing ribs and at the intersection of the second and third reinforcing ribs. These protrusions can not only disperse stress concentration, improve node strength, change the structural vibration transmission path, and reduce noise radiation, but also form an organic whole with the reinforcing rib system to jointly extend the structural fatigue life and improve overall reliability.

[0016] 4. This utility model sets a sunken platform at the four corners of the cover plate body, and uses the thickness of the fourth reinforcing rib to be higher than the thickness of the sunken platform to form a reasonable thickness gradient distribution. The thickness is appropriately increased in the reinforcing rib area of ​​critical stress to ensure sufficient load-bearing capacity, while the thickness is kept thinner in non-critical areas. This can increase the overall rigidity while avoiding excessive weight of the cover plate body. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 4 As shown, an air compressor cylinder cover plate includes a cover plate body 1, which has a cubic structure. The cover plate body 1 has rounded chamfers 8 at the four corners. The chamfers 8 are used to effectively alleviate the stress concentration problem caused by the traditional right-angle structure, and at the same time provide assembly guidance function, making the installation process more convenient and safe.

[0020] The cover plate body 1 is provided with a sunken platform at each of the four corners. The sunken platform has a semi-circular structure to make the pressure distribution on the sealing surface more uniform. The cover plate body 1 is provided with a threaded hole 3 at the center of the sunken platform at each of the four corners. The threaded hole 3 is used to ensure a reliable connection with the compressor body, improve the reliability of the connection and the ease of assembly.

[0021] The lower surface of the cover plate body 1 is provided with three second reinforcing ribs 2 from the center outward. The second reinforcing ribs 2 are in the form of concentric rings, and the three concentric rings of the second reinforcing ribs 2 are distributed with non-uniform spacing (the spacing of the outer rings is larger). The semi-circular cross section is used to form a multi-level support structure to reduce vibration amplitude, improve bending stiffness, promote radial heat diffusion, and improve temperature gradient distribution.

[0022] Four outwardly extending first reinforcing ribs 4 are provided at the center of the lower surface of the cover plate body 1. The first reinforcing ribs 4 are evenly distributed at 90° to form a support frame. The first reinforcing ribs 4 and the second reinforcing ribs 2 intersect to form a grid-like reinforcement structure, which together divides the cover plate body 1 into multiple small areas to improve the bending stiffness of the cover plate body 1, effectively suppress vibration and reduce radiated noise. In addition, the first reinforcing ribs 4 and the second reinforcing ribs 2 serve as heat conduction paths, which can increase the heat dissipation surface area, reduce the operating temperature of the compressor cylinder, and achieve a heat dissipation effect.

[0023] The cover plate body 1 is provided with a third reinforcing rib 5 at the position corresponding to the arc edge of the sunken platform. The third reinforcing rib 5 has a semi-circular structure and is intersected with the second reinforcing rib 2. It is used to improve local stiffness, reduce stress concentration coefficient and extend fatigue life. The intersection of the third reinforcing rib 5 and the second reinforcing rib 2 forms a mechanical node, which forms a continuous reinforcement with the edge of the sunken platform and participates in the construction of a complete force flow transmission network. It effectively overcomes the problem of insufficient stiffness in the corner area of ​​traditional structures, significantly improves the stress distribution state and comprehensively improves the reliability of the sealing system.

[0024] A fourth reinforcing rib 6 is provided at each of the four edges of the cover plate body 1. This fourth reinforcing rib 6 has a U-shaped structure and connects to the third reinforcing ribs 5 at both ends, forming a closed loop. This is used to improve the stiffness of the edge area, reduce the stress concentration factor, and effectively change the edge vibration mode. Figure 4 As shown, the thickness (L1) of the fourth reinforcing rib 6 is higher than the thickness (L2) at the sinking platform, which can increase the overall rigidity while avoiding excessive weight of the cover plate body 1.

[0025] A protrusion 7 is provided at the intersection of the first reinforcing rib 4 and the second reinforcing rib 2, as well as at the intersection of the second reinforcing rib 2 and the third reinforcing rib 5. The protrusion 7 has a cylindrical structure and is used to disperse stress concentration and improve the strength of the node. It can not only change the vibration transmission path of the structure, reduce the resonance peak, and reduce noise radiation, but also form an organic whole with the reinforcing rib system to jointly extend the fatigue life of the structure and improve the overall reliability.

[0026] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: This invention employs an innovative composite reinforcing rib structure design consisting of a first reinforcing rib, a second reinforcing rib, a third reinforcing rib, and a fourth reinforcing rib. This design creates a complete mechanically optimized structure on the cover plate body, improving overall bending stiffness, optimizing natural frequency, and effectively avoiding resonance. Simultaneously, the grid-like layout of multiple reinforcing ribs divides the cover plate into several small areas, reducing sound radiation efficiency and noise levels. Furthermore, the intersecting arrangement of multiple reinforcing ribs forms a heat conduction path, optimizing the heat dissipation function of the cover plate body, lowering the operating temperature, ensuring the normal operation of the compressor cylinder, and extending its service life.

[0027] Furthermore, this utility model provides rounded chamfers at the four corners of the cover plate body. The rounded transition effectively alleviates the stress concentration problem caused by the traditional right-angle structure, while also providing assembly guidance, making the installation process more convenient and safe. In addition, the chamfers form good structural continuity with the fourth reinforcing rib and the first reinforcing rib, ensuring the overall stiffness distribution while avoiding local stress peaks, thus improving the reliability, assemblability, and service life of the cover plate body.

[0028] Furthermore, this utility model provides protrusions at the intersections of the first and second reinforcing ribs and the second and third reinforcing ribs. These protrusions not only disperse stress concentration, improve node strength, change the structural vibration transmission path, and reduce noise radiation, but also form an organic whole with the reinforcing rib system, jointly extending the structural fatigue life and improving overall reliability.

[0029] Furthermore, this utility model sets a sunken platform at the four corners of the cover plate body, and utilizes the fact that the thickness of the fourth reinforcing rib is higher than the thickness of the sunken platform to form a reasonable thickness gradient distribution. The thickness is appropriately increased in the reinforcing rib area where the stress is critical to ensure sufficient load-bearing capacity, while the thickness is kept thinner in non-critical areas. This can increase the overall rigidity while avoiding excessive weight of the cover plate body.
