Description

Technical Field

[0001] This application relates to the field of hydraulic mechanical component technology, specifically to the field of modular hydraulic integrated block technology. Background Technology

[0002] Hydraulic manifolds, as key components in modern hydraulic systems, are widely used in industrial fields by integrating multiple hydraulic valves, channels, and other control elements into a compact structure.

[0003] It integrates multiple hydraulic valves, channels and other control elements into a compact structure, and can be used with various types of actuators (such as hydraulic cylinders and motors), sensors (such as pressure sensors and temperature sensors), and control valves (such as directional control valves and pressure control valves).

[0004] However, due to this characteristic, in practical applications, traditional single-unit hydraulic integrated blocks are difficult to meet the diverse needs of highly customized applications, and because all functions are integrated into a single structure, maintenance is difficult when a component malfunctions.

[0005] In response, the concept of modular hydraulic integrated blocks was proposed. However, modular design still has problems such as interface sealing, pressure loss, and turbulence. Summary of the Invention

[0006] To address the aforementioned problems, this application proposes a modular hydraulic integrated block, which aims to improve at least one of the problems mentioned above by optimizing the modular design of the hydraulic integrated block.

[0007] To achieve the above objectives, the present application adopts the following technical solution:

[0008] A modular hydraulic integrated block includes a front module, a rear module, and an intermediate module disposed between the front module and the rear module, all having the same outer peripheral shape and the same guide shaft hole. The front module, rear module, and intermediate module can be fixed in series by guide columns.

[0009] The front, middle, and rear modules are respectively provided with an oil pressure port and an oil outlet. The rear of the front and middle modules are respectively provided with an oil distribution port communicating with the oil pressure port and an oil return port communicating with the oil outlet. The oil pressure port and the oil outlet of the rear module are connected inside the rear module.

[0010] Thus, designing the hydraulic integrated blocks with the same outer peripheral shape and guide shaft hole in a modular design can significantly enhance expansion, replacement, and maintenance capabilities. Simultaneously, the oil inlet and outlet ports correspond to each other between modules, meaning that the main oil circuits can be directly designed in a straight line, effectively reducing pressure loss and turbulence while achieving modular design.

[0011] Furthermore, in order to improve the sealing performance between the modules, sealing rings are provided on the outer periphery of the oil pressure port and the oil outlet.

[0012] In some possible implementations, the number of sealing rings is one, and the oil pressure port and oil outlet are covered by the inner ring.

[0013] In some possible implementations, a rectifier ring is also included on the module located on the oil inlet side of the oil circuit. This ring can improve the turbulence caused by the excessive length of the oil circuit due to the modular design, and rectify the oil circuit when it is transferred between modules, thereby improving the overall stability of the hydraulic integrated block.

[0014] In some possible implementations, the rectifier ring includes an oil passage cylinder, support ports disposed at both ends of the oil passage cylinder, and a support column connecting the support ports;

[0015] It also includes an oil-draining ring that guides the movement of the support column and opens or closes the oil passage.

[0016] Thus, by setting an oil-draining ring on the continuous flow path cylinder, the oil is guided in a ring shape through the oil passage, reducing turbulence. At the same time, the oil-draining ring can be guided and moved on the support column, which can open and close the oil passage, thereby achieving the error-proofing and inspection function of the modular design.

[0017] To prevent the grease-repellent ring from being squeezed and deformed when it is used to close the oil passage, the grease-repellent ring has a contact portion in the middle part that is higher than the diameter of the support column.

[0018] In a preferred embodiment, the fitting part is located on the side where the fitting part and the support port contact when the oil circuit is opened.

[0019] In some possible implementations, the oleophobic ring is provided with an oil-blocking portion recessed in the direction of oil passage closure.

[0020] In order to facilitate the switching of the oil passage from the closed oil passage state to the open oil passage state, the oil passage cylinder is provided with a sealing protrusion in the direction of the open oil passage state, which gradually increases in inclination angle towards the oil passage ring.

[0027] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0028] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0030] Please refer to Figure 1 and Figure 2 The hydraulic manifold has an oil pressure port 1 and an oil outlet port 2, as well as accessory holes 300 that connect to various control components through internal channels. Different control components can be installed here as needed, such as actuators (e.g., hydraulic cylinders, motors), sensors (e.g., pressure sensors, temperature sensors), and control valves (e.g., directional control valves, pressure control valves). The number and diameter of the accessory holes 300 vary depending on the control component.

[0031] In order to enable the hydraulic integrated block to adapt to various control elements, this application adopts a modular design, that is, different control elements use different modules, and then the modules are connected in series to form a hydraulic integrated block.

[0032] At this point, the main issues to consider include sealing, pressure loss caused by multiple modules connected in series, turbulence caused by adjustments of various control elements and excessively long oil circuits.

[0033] Please continue to refer to this. Figure 1 and Figure 2 This application discloses a modular hydraulic integrated block comprising a front module 10, a rear module 20, and an intermediate module 30 disposed between the front module 10 and the rear module 20, all having the same outer peripheral shape. The number and type of the intermediate modules 30 can be freely adjusted according to requirements; in this embodiment, one intermediate module 30 is used for ease of understanding. In this specification, the terms "module" and "each module" will be used to describe the front module 10, rear module 20, and intermediate module as described above.

[0034] At this point, each module has the same guide shaft hole 100 at the same position, that is, at the four corners, and can be fixed in series by the guide post 200. One guide post 200 is marked in the attached drawing, but there are actually four corners. Fixing several modules using guide posts 200 is a common method in mold design, and will not be elaborated on further. Thus, designing the hydraulic integrated blocks with a modular design of identical outer circumference and guide shaft hole 100 can significantly enhance expansion, replacement, and maintenance capabilities.

[0035] At this point, an oil pressure port 1 and an oil outlet 2 are respectively provided at the front end of the front module 10, the middle module 30, and the rear module 20. Simultaneously, an oil distribution port communicating with the oil pressure port 1 and an oil return port communicating with the oil outlet 2 are respectively provided at the rear end of the front module 10 and the middle module 30. The positions of the oil distribution port and the oil return port correspond to those of the oil pressure port 1 and the oil outlet 2, but are not shown in the attached drawings. At this point, the oil pressure port 1 and the oil outlet 2 of the rear module 20 are connected internally within the rear module 20. This means that the main oil circuit can be directly designed in a straight line, effectively reducing pressure loss and turbulence.

[0036] The linear design, using guide columns 200 in series, can present sealing issues, especially when the number of intermediate modules 30 increases. However, the hydraulic manifold itself is a precision-machined component, and the oil circuit connections have built-in seals. Therefore, the main concern here is ensuring that localized leaks caused by seal aging or other reasons do not affect the working environment.

[0037] To address this, a sealing ring 3 is provided around the outer periphery of the oil pressure port 1 and the oil outlet 2. Preferably, there is one sealing ring 3, which covers the oil pressure port 1 and the oil outlet 2 within the inner ring. That is, the sealing ring 3 mainly serves to assist in sealing and to buffer and stabilize when multiple intermediate modules 30 are connected in series.

[0038] As mentioned above, in addition to sealing, the oil pressure is increased during oil supply to reduce the impact of pressure loss when the distance is long. Considering the impact of multiple different control components working at the same time, there is a risk of turbulence.

[0039] Please refer to Figures 1 to 3 To address this, the rectifier ring 4 on the oil inlet side module can improve turbulence caused by the excessively long oil circuit due to the modular design. The oil inlet direction is from the front module 10 to the rear module 20 during oil pressure (supply), meaning the rectifier ring 4 is located in the direction of the front module 10, i.e., the forward-facing module. During oil return, the rectifier ring 4 is located in the direction of the rear module 20, i.e., the backward-facing module. This rectifies the oil flow as it transfers between modules, improving the overall stability of the hydraulic integrated block.

[0040] For one implementation method of rectifier ring 4, please refer to the following reference. Figures 3 to 6 The rectifier ring 4 includes an oil passage cylinder 41, support ports 42 disposed at both ends of the oil passage cylinder 41, and a support column 43 connecting the support ports 42. Further, it also includes an oleophobic ring 44 that guides the movement of the support column 43 and opens or closes the oil passage. The oleophobic ring 44 can be made of elastic rubber or similar material, and opens or closes the oil passage by elastically deforming and pressing against the oil passage cylinder 41.

[0041] Thus, by setting an oil-draining ring 44 on the continuous flow path cylinder 41, the oil passage is guided in a ring shape through the oil-draining ring 44, thereby reducing turbulence. At this time, the oil-draining ring 44 is driven by the oil pressure of the oil passage to open or close the oil passage, and it also plays a role in preventing mistakes and verifying the modular design.

[0042] Furthermore, if the oil circuit is shut off, the grease trap 44 will be subjected to continuous oil pressure. This situation can be understood as reverse connection during modular installation, etc. To prevent the grease trap 44 from being squeezed and deformed under these conditions, the grease trap 44 has a contact portion 441 in its middle part that is higher than the diameter of the support column 43. That is, the contact portion 441 has a longer distance, so even if it is subjected to pressure, its distribution area is longer, thus avoiding deformation.

[0043] Meanwhile, the orientation of the contact portion 441 is preferably the side where the contact portion 441 and the support port 42 contact when the oil passage is opened. At this time, the oil-blocking portion 442 will be in the opposite direction. The oil pressure of opening the oil passage will push the oil-blocking portion 442, while the contact portion 441 will press against the support port 42. A gap will be formed between the oil-blocking portion 442, the oil passage cylinder 41, and the support port 42, which will fully guide the oil and improve the turbulence problem.

[0044] Please refer to Figure 6When the oil circuit is closed, the grease trap 44 has an oil-blocking portion 442 recessed in the direction of oil circuit closure, which can increase the uniformity of force on the grease trap 44. When the grease trap 44 is subjected to uniform and stable force, the sealing effect between its oil-blocking portion 442 and the oil circuit cylinder 41 is also better. However, if the seal is too tight, it will be difficult to switch from the closed oil circuit state to the open oil circuit state.

[0045] Please refer to Figure 5 and Figure 6 To address this, the oil passage cylinder 41 is provided with a sealing protrusion 411 whose inclination angle gradually increases towards the oil-retaining ring 44 in the direction of the open oil passage. This design, with a smaller inclination angle compared to a recessed feature, prevents the oil-blocking portion 442 of the oil-retaining ring 44 from jamming when the oil passage is closed. Here, the direction of the open oil passage refers to the direction of the closed oil passage. Figure 6 In this context, the oleophobic ring 44 moves toward the support port 42.

[0046] As stated above, this application protects a modular hydraulic integrated block, and all technical solutions that are the same as or similar to this application should be considered to fall within the protection scope of this application.
