Description

Technical Field

[0001] This utility model relates to the field of camshaft assembly technology, and in particular to a camshaft assembly for a high-pressure pump. Background Technology

[0002] The camshaft assembly plays a crucial role in high-pressure pumps. It typically consists of a camshaft body, cams, and related components. The camshaft rotates to drive the cams, controlling the operation of the high-pressure pump with a specific motion trajectory. The design of this assembly must consider high precision and high reliability to ensure stable operation under high-pressure environments. Its materials usually possess high strength and wear resistance, capable of withstanding prolonged operation and high pressure. The performance of the camshaft assembly directly affects the output pressure and flow rate of the high-pressure pump. It is widely used in automotive engines, industrial equipment, and other fields, providing stable high-pressure fluid power to these devices. In practical applications, the camshaft assembly of a high-pressure pump typically requires the following technologies:

[0003] 1. The profile accuracy of the camshaft directly affects the working performance of the high-pressure pump. High-precision machining equipment and processes are required to ensure that the profile accuracy of the camshaft meets the requirements.

[0004] 2. Camshafts bear significant loads and friction during operation, requiring the use of high-strength materials, such as alloy steel, to ensure their reliability and durability.

[0005] 3. The friction between the camshaft and other components requires good lubrication to reduce wear and energy loss. A well-designed lubrication system is necessary to ensure the camshaft receives adequate lubrication during operation.

[0006] 4. Camshafts generate significant centrifugal force when rotating at high speeds, requiring dynamic balancing to reduce vibration and noise and improve operational stability.

[0007] 5. The assembly accuracy of the camshaft assembly directly affects its working performance and reliability. Advanced assembly equipment and processes are required to ensure that the assembly accuracy between each component meets the requirements.

[0008] Currently, manufacturers employ various equipment and methods to achieve the functionality of camshaft assemblies used in high-pressure pumps. For high-precision machining, CNC machining centers and other high-precision equipment are used, along with advanced machining processes such as grinding and honing, to ensure the camshaft's contour accuracy meets requirements. Regarding high-strength materials, suitable alloy steel is selected and subjected to heat treatment and other processes to improve the material's strength and hardness. For lubrication, a well-designed lubrication system is employed, using pressure lubrication or splash lubrication to ensure adequate lubrication of the camshaft during operation. For dynamic balancing, dynamic balancing machines are used to perform dynamic balancing of the camshaft, and balance weights are added to minimize centrifugal force during high-speed rotation. For assembly, automated assembly equipment and processes are used to ensure that the assembly accuracy between various components meets requirements.

[0009] However, the above approach has a significant hardware structural problem: in some special working scenarios, due to the fixed size of the camshaft assembly, it may not meet the installation requirements of specific angles or positions. For example, in complex industrial equipment with strict requirements on component size and shape, the camshaft assembly may not be adaptable, rendering it unusable. This application proposes a solution to this problem by designing a telescopic end cap. This allows the camshaft assembly to better adapt to different working environments and installation needs, improving its versatility. Utility Model Content

[0010] (a) Technical problems to be solved

[0011] To address the shortcomings of existing technologies, this utility model provides a camshaft assembly for high-pressure pumps, which solves the technical problem that the fixed dimensions of the camshaft assembly may not meet the installation requirements of specific angles or positions.

[0012] (II) Technical Solution

[0013] To achieve the above objectives, this utility model provides the following technical solution:

[0014] A camshaft assembly for a high-pressure pump includes a camshaft assembly whole, with assembly ports at both ends of the camshaft assembly whole. The camshaft assembly for the high-pressure pump also includes an extension mechanism, including a connecting rod and two fixed posts. The interior of the camshaft assembly whole has a slot, and both ends of the camshaft assembly whole are provided with threaded grooves. The two threaded grooves are symmetrically distributed, and threaded posts are fixedly connected to the opposite ends of the two assembly ports.

[0015] Preferably, both threaded posts are threadedly connected to the camshaft assembly via corresponding threaded grooves.

[0016] Preferably, each of the two threaded posts has a hole through its side end, and each of the two threaded posts has a fixing post inside.

[0017] Preferably, the opposite sides of both assembly ports are fixedly connected to the corresponding fixing posts.

[0018] Preferably, each of the two fixed posts has a hole at one of its opposite ends.

[0019] Preferably, both ends of the connecting rod are movably connected to the corresponding holes.

[0020] Preferably, both ends of the connecting rod are fixedly connected to limit blocks, and each limit block is located inside the corresponding hole.

[0021] Preferably, the inner walls of the two fixed columns each have two limiting grooves, and each limiting block is slidably connected to the corresponding fixed column through the limiting groove.

[0022] (III) Beneficial Effects

[0023] 1. When the operator needs to adjust the overall length of the camshaft assembly, the operator rotates the assembly port. One end of the assembly port drives the other end of the assembly port to rotate through the connecting rod. When the two assembly ports rotate, the threaded post will continuously disengage from the threaded groove. When the threaded post disengages from the threaded groove, it will push the two assembly ports to achieve the purpose of extending the overall camshaft assembly. This allows the camshaft assembly to better adapt to different working environments and installation requirements, thus improving its versatility.

[0024] 2. When the two assembly ports extend, they will drive the corresponding fixed posts to move. When the fixed posts move, the connecting rod remains stationary. When the two fixed posts move to a certain distance, the limiting block on the connecting rod will abut against the inner wall of the fixed posts, so that the two assembly ports will not move too far away from the camshaft assembly as a whole, thus preventing the assembly ports from detaching from the camshaft assembly as a whole.

[0031] This application provides a camshaft assembly for a high-pressure pump, effectively solving the technical problem that the fixed size of the camshaft assembly may not meet the installation requirements of specific angles or positions. When the operator needs to adjust the overall length of the camshaft assembly, the operator rotates the assembly port. One end of the assembly port drives the other end of the assembly port to rotate through a connecting rod. When the two assembly ports rotate, the threaded post will continuously disengage from the threaded groove. When the threaded post disengages from the threaded groove, it will push the two assembly ports to achieve the purpose of extending the overall camshaft assembly. This allows the camshaft assembly to better adapt to different working environments and installation requirements, improving its versatility.

[0032] Example

[0033] The technical solution in this application embodiment effectively solves the technical problem that the fixed size of the camshaft assembly may not meet the installation requirements of specific angles or positions. The overall idea is as follows:

[0034] To address the problems existing in the prior art, this utility model provides a camshaft assembly for a high-pressure pump, including a camshaft assembly whole 11, with assembly ports 12 at both ends of the camshaft assembly whole 11. This camshaft assembly for a high-pressure pump also includes an extension mechanism, comprising a connecting rod 17 and two fixed posts 15. The camshaft assembly whole 11 has a hollow groove at its interior, and threaded grooves 13 are provided at both ends of the camshaft assembly whole 11. The two threaded grooves 13 are symmetrically distributed. A threaded post 14 is fixedly connected to one end of each of the two assembly ports 12. Both threaded posts 14 are threadedly engaged with the camshaft assembly whole 11 through their corresponding threaded grooves 13. When the operator needs to adjust the length of the camshaft assembly whole 11, the operator rotates the assembly ports 12. One end of the assembly port 12 rotates through the connecting rod 17, causing the threaded posts 14 to continuously disengage from the threaded grooves 13. When the threaded posts 14 disengage from the threaded grooves 13, they push the two assembly ports 12.

[0035] Both threaded posts 14 have through holes 16 on their sides, and both threaded posts 14 have fixing posts 15 inside. The opposite sides of the two assembly ports 12 are fixedly connected to the corresponding fixing posts 15. The opposite ends of the two fixing posts 15 are each provided with holes 19. Both ends of the connecting rod 17 are movably connected to the corresponding holes 19, thereby extending the camshaft assembly as a whole 11. This allows the camshaft assembly to better adapt to different working environments and installation requirements, improving its versatility.

[0036] Both ends of the connecting rod 17 are fixedly connected to limit blocks 18. Each limit block 18 is located inside the corresponding hole 19. The inner walls of the two fixed posts 15 are provided with two limit grooves 20. Each limit block 18 is slidably connected to the corresponding fixed post 15 through the limit groove 20. When the two assembly ports 12 extend, the two assembly ports 12 will drive the corresponding fixed posts 15 to move. When the fixed posts 15 move, the connecting rod 17 remains stationary. When the two fixed posts 15 move a certain distance, the limit blocks 18 on the connecting rod 17 will abut against the inner wall of the fixed posts 15, so that the two assembly ports 12 will not move too far away from the camshaft assembly 11, causing the assembly ports 12 to detach from the camshaft assembly 11.

[0037] Working principle:

[0038] When the operator needs to adjust the length of the camshaft assembly 11, the operator rotates the assembly port 12. One end of the assembly port 12 drives the other end of the assembly port 12 to rotate via the connecting rod 17. When the two assembly ports 12 rotate, the threaded post 14 continuously disengages from the threaded groove 13. When the threaded post 14 disengages from the threaded groove 13, it pushes the two assembly ports 12, thereby extending the camshaft assembly 11. This allows the camshaft assembly to better adapt to different working environments and installation requirements, improving its versatility. When the two assembly ports 12 extend, they will drive the corresponding fixed post 15 to move. When the fixed post 15 moves, the connecting rod 17 remains stationary. When the two fixed posts 15 move a certain distance, the limiting block 18 on the connecting rod 17 will abut against the inner wall of the fixed post 15, preventing the two assembly ports 12 from moving too far away from the camshaft assembly 11 and causing the assembly ports 12 to disengage from the camshaft assembly 11.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
