Description

Technical Field

[0001] This application relates to the field of pipeline liquid distribution technology, and in particular to a modular liquid distribution assembly and a CNC machine tool. Background Technology

[0002] Existing fluid distribution devices have significant technical shortcomings in the distribution of cutting fluids, coolants, and other media in the machinery manufacturing industry. The number and specifications of their branch pipes are fixed after manufacturing, making it impossible to flexibly adjust according to actual distribution needs. This results in a single device only being suitable for specific machine models or fixed distribution scenarios. When the distribution quantity or usage scenario changes, it is difficult to quickly adapt to new requirements, limiting its applicability. When it is necessary to expand the number of branch pipes, the entire fluid distribution device must be disassembled from the existing pipeline before construction, making the operation complex and difficult. Furthermore, expansion typically relies on threaded connections, requiring additional pipe fittings and other connectors, which not only increases the complexity of the expansion operation but also leads to higher expansion costs.

[0032] A modular liquid dispensing assembly according to an embodiment of the first aspect of this application, such as Figures 1 to 5 As shown, the modular liquid distribution assembly includes at least one liquid distribution block 1, and when the number of liquid distribution blocks 1 is greater than or equal to two, the liquid distribution blocks 1 are connected end to end. Each liquid distribution block 1 includes a liquid distribution block body 11, on which a first passage interface 111, a second passage interface 112, and a branch interface 113 are provided. The first passage interface 111 is located at the first end along the length of the liquid distribution block body 11; the second passage interface 112 is located at the second end along the length of the liquid distribution block body 11, and the first passage interface 111 and the second passage interface 112 are connected through a main passage. The branch interface 113 is located on the side along the length of the liquid distribution block body 11 to form a branch pipeline; the branch interface 113 is connected to the main passage through a branch passage. The second passage interface 112 of the preceding liquid distribution block 1 is connected to the first passage interface 111 of the following liquid distribution block 1 to form a liquid passage. The number of branch pipelines in the modular liquid distribution assembly can be changed by adjusting the number of liquid distribution blocks 1. The branch interface 113 can be specifically set on the upper surface of the liquid distribution block body 11.

[0033] The first access interface 111 and the second access interface 112 can be threaded interfaces to facilitate the subsequent installation of pipe fittings 3 or plugs 4. The branch interface 113 can be threaded interfaces to facilitate the subsequent installation of connecting elbows 5.

[0034] The modular liquid distribution assembly effectively solves the problem of traditional liquid distribution devices having a fixed number of branch lines and being difficult to adapt to different operating conditions by using a standardized liquid distribution block 1 as the basic component. Because each liquid distribution block 1 has a unified and standardized structure, mass production can be achieved, reducing redundant costs in mold development and production processes, and simplifying component management. Users can flexibly add or remove liquid distribution blocks 1 according to the actual number of branch lines required, without needing to customize an entire device for different branch requirements, greatly improving the versatility and ease of use of the assembly. This design allows the assembly to be quickly adapted to different scenarios such as machining and automated production lines, whether it's a simple device requiring a few branch lines or a complex system requiring many branch lines, reducing user operating costs and equipment investment.

[0035] The rational layout of the main and branch passages on the main body 11 of the distributor block ensures the stability and uniform distribution of media such as cutting fluid and coolant during the flow process, avoiding problems such as flow fluctuations or distribution imbalances caused by unreasonable pipeline design. The connection method of each distributor block 1 through the first passage interface 111 and the second passage interface 112 simplifies the assembly process. No complex connecting tools or professional skills are required; ordinary operators can complete the assembly, significantly improving assembly efficiency. At the same time, this modular structure also has significant advantages in maintenance. When a distributor block 1 malfunctions or is damaged, it can be directly disassembled and replaced individually without disassembling the entire assembly, reducing maintenance downtime, lowering maintenance difficulty and costs, and further improving the economic efficiency and practicality of the component.

[0036] In some embodiments, the cross-sectional shape of the liquid distribution block 1 is not only rectangular, but can also be a rounded rectangle, a circle, etc. In other words, the liquid distribution block 1 can be a rectangular block, or a cylinder or other form of frustum structure. Correspondingly, the surfaces where the first passage interface 111, the second passage interface 112 and the branch interface 113 of the liquid distribution block 1 are located can be rectangular, or they can be other shapes such as circular flange surfaces.

[0037] In some embodiments, an adjustable flow control component, such as a miniature throttle valve or a flexible valve core structure, can be added to each branch passage of the liquid distribution block 1. By rotating the adjustment knob or replacing the valve core with one of different orifice diameters, the proportion of medium flow in the corresponding branch pipeline can be controlled independently. This extended design can meet the differentiated requirements of different branch pipelines for medium flow. For example, in multi-station processing equipment, the flow can be precisely allocated according to the cooling requirements of different processing steps, thereby improving the efficiency of medium utilization.

[0038] According to one embodiment of this application, such as Figure 1 and Figure 2As shown, each individual dispensing block 1 has two first-path interfaces 111 and two second-path interfaces 112, spaced apart along the width of the dispensing block 1; two sets of branch interfaces 113 are also provided. Each set of branch interfaces 113 can have three interfaces, for a total of six interfaces in two sets.

[0039] The structural design of dual first-path interfaces 111 and dual second-path interfaces 112 allows a single liquid distribution block 1 to flexibly adapt to core application scenarios of "two-way water inlet" or "water inlet + water return," effectively solving the problem that traditional single-main-path liquid distribution blocks 1 cannot handle multiple media supply or media circulation. In the "two-way water inlet" scenario, the two main paths can respectively transport different types of media (such as cutting fluids with different formulations), or simultaneously transport the same media to increase the total flow rate. The two sets of branch interfaces 113 are correspondingly distributed to downstream workstations, eliminating the need for additional liquid distribution devices and simplifying the system pipeline layout. In the "water inlet + water return" scenario, one main path serves as the water inlet path, transporting media to each workstation through the corresponding branch interface 113, while the other main path serves as the water return path.

[0040] This structural design expands functionality by utilizing space in the width direction without increasing the length of the dispensing block 1, making the structure of the dispensing block 1 more compact and saving installation space. It is especially suitable for scenarios where the internal space of the equipment is limited but multiple media or multiple branch distributions are required.

[0041] The corresponding arrangement of the two main channels and two sets of branch interfaces 113 maintains the standardized design characteristics of the distributor block 1 and does not affect the end-to-end connection assembly between multiple distributor blocks 1. Users can combine multiple distributor blocks 1 of this structure as needed to form combinations with more main channels and more sets of branch pipelines, further expanding the application range of modular distributor components. At the same time, this structure still has the advantage of modularity during maintenance. When a certain main channel or a certain set of branch interfaces 113 fails, the distributor block 1 can be repaired or replaced individually without affecting the normal operation of other pipelines, reducing maintenance costs and downtime.

[0042] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, a first heat insulation groove 114 is provided between the two sets of branch interfaces 113. The first heat insulation groove 114 is used to restrict heat transfer of the liquid in the two sets of branch passages. Figure 2 The length of the first insulation groove 114 shown is less than Figure 1 The length of the first insulation tank 114 shown is because the first insulation tank 114 forms a stepped structure within the liquid distribution block body 11. Figure 2 The short grooves at both ends of the first insulation tank 114 are fixed grooves 118, which are used to fix the liquid distribution block 1 in a preset position.

[0043] The first insulation tank 114 solves the problem of heat transfer caused by close contact between liquids in two branch channels, making it particularly suitable for the core application scenario of "inlet water + return water". When one branch channel carries low-temperature inlet water and the other carries high-temperature return water, the first insulation tank 114 can effectively block the heat exchange between the two, preventing the low-temperature inlet water from being heated by the return water and reducing its cooling effect, while preventing the high-temperature return water from affecting the subsequent recycling efficiency due to heat loss. In the "two-way inlet water" scenario, if the two branch channels carry media with different temperature requirements (such as constant temperature cutting fluid required by different processes), the first insulation tank 114 can prevent temperature interference between the two media, ensuring that each maintains its preset temperature state and guaranteeing the processing accuracy or process stability of downstream equipment.

[0044] This structural design achieves thermal insulation while maintaining the modular core characteristics and compact layout of the liquid distribution block 1. The first thermal insulation groove 114 does not require a large amount of additional installation space and can be integrally formed with the main body of the liquid distribution block 11, without increasing assembly difficulty or affecting the connection stability between the liquid distribution blocks 1 through the first passage interface 111 and the second passage interface 112. At the same time, the integrated design eliminates the need for additional complex thermal insulation components, simplifying the production process and controlling manufacturing costs. While improving the functionality and practicality of the component, it retains all the advantages of the original modular design, further expanding the component's adaptability in scenarios such as precision machining and chemical production where temperature control is required.

[0045] In some embodiments, a low thermal conductivity insulating material (such as ceramic fiber, polyurethane foam, etc.) can be filled inside the first insulating tank 114 to enhance the insulation effect through the insulating properties of the material itself. This is especially suitable for working conditions with large temperature differences, further reducing heat transfer and ensuring the stability of the liquid temperature in the two branch passages.

[0046] According to one embodiment of this application, such as Figures 6 to 8 As shown, the modular liquid distribution assembly also includes parallel connecting blocks 2; the liquid distribution blocks 1 are divided into multiple groups, with at least one liquid distribution block 1 in each group; the multiple liquid distribution blocks 1 form parallel liquid passages through the parallel connecting blocks 2. Each parallel connecting block 2 can simultaneously connect two or more groups of passages, such as... Figure 8 The diagram shows a parallel connection block 2 that connects two sets of paths in parallel.

[0047] The parallel connecting block 2 can be provided with an assembly through hole 23. Screws can be inserted into the assembly through hole 23 and the connecting hole 117 to connect the parallel connecting block 2 and the liquid separating block 1.

[0048] The parallel connecting block 2 solves the problem of limited total flow rate and difficulty in adapting to high-flow-rate media delivery requirements in traditional series-type liquid distribution components. The multi-component liquid blocks 1 form independent parallel flow channels through the parallel connecting block 2. Each group of flow channels can simultaneously deliver media, significantly improving the total flow capacity of the modular liquid distribution component. This is suitable for scenarios requiring simultaneous supply of media to numerous workstations or high-flow-rate media at a single workstation (such as large automated production lines and multi-spindle machining equipment). Each component liquid block 1 retains its modular characteristics, allowing for flexible adjustment of the number of liquid blocks 1 within a single group according to the branching requirements of the corresponding workstation. This satisfies both the overall high-flow-rate delivery requirements and adapts to the differentiated branching requirements of different workstations, eliminating the need to redesign the entire liquid distribution system for high-flow-rate demands and greatly improving the component's adaptability to various scenarios.

[0049] This parallel structure offers significant advantages in operational stability and ease of maintenance. Each group of liquid-passing channels operates independently. When a component liquid block 1 malfunctions or requires maintenance, that group of channels can be shut down individually while other groups continue to operate normally. This avoids the problem of a single component failure causing the entire system to shut down, as seen in traditional series structures, thus reducing the risk of production interruptions. Simultaneously, the design of the parallel connecting block 2 simplifies the integration and assembly process of the multi-component liquid blocks 1. Each component liquid block 1 can be quickly connected to the parallel connecting block 2 without complex piping layouts, improving assembly efficiency. Furthermore, this structure retains the advantages of standardized production of the liquid blocks 1, while the parallel connecting block 2 can also be mass-produced, further controlling overall manufacturing costs and balancing high flow rate requirements with economic efficiency.

[0050] According to one embodiment of this application, such as Figure 6 and Figure 7 As shown, the parallel connecting block 2 is provided with a main connecting passage extending along its length. The main connecting passage forms a third passage interface 21 at both ends along the length of the parallel connecting block 2. Two main connecting passages can be provided to correspond to the liquid separator 1. A fourth passage interface 22 for communicating with the first passage interface 111 is also provided on the side of the parallel connecting block 2. A second heat insulation groove 24 can be provided between the two main connecting passages of the parallel connecting block 2.

[0051] The main connection path extends along the length of the parallel connection block 2, providing a centralized fluid distribution channel for the parallel connection of multi-component liquid blocks 1. After the medium enters the main connection path through the third channel interface 21, it can flow evenly along the length of the path to each fourth channel interface 22, and then connect to the first channel interface 111 of the liquid distribution block 1 through the fourth channel interface 22, ensuring that each group of parallel liquid distribution blocks 1 can obtain a stable medium supply and guaranteeing the consistency of medium distribution at each downstream station. This centralized path design is particularly suitable for high-flow parallel scenarios, improving the total liquid throughput capacity while maintaining the stability of medium delivery, meeting the flow uniformity requirements of large equipment or multi-station systems.

[0052] The fourth access interface 22 is located on the side and multiple interfaces can be flexibly arranged along the length of the main connection channel to accommodate the parallel connection requirements of different numbers of liquid distribution blocks 1. Users can increase or decrease the number of fourth access interfaces 22 or the number of liquid distribution blocks 1 according to the number of workstations without changing the core structure of the parallel connection block 2. At the same time, this interface layout allows the connecting pipes of each component liquid block 1 to be arranged along the side of the parallel connection block 2, reducing pipe crossing interference and facilitating later maintenance. When a component liquid block 1 needs maintenance, the connection of the corresponding fourth access interface 22 can be directly disconnected without affecting the normal operation of the main connection channel and other component liquid blocks 1.

[0053] According to one embodiment of this application, such as Figure 7 As shown, along the length of the parallel connecting block 2, the fourth channel interface 22 is arranged in two or more rows; along the width of the parallel connecting block 2, the fourth channel interface 22 is arranged in two groups.

[0054] The fourth channel interface 22 is arranged in two sets along the width direction, adapting to the liquid distribution block 1 with the dual-channel structure described above. Each set of fourth channel interfaces 22 can be connected to one of the main channels (such as the water inlet channel and the water return channel) of the liquid distribution block 1, enabling the two main channels of the dual-channel liquid distribution block 1 to achieve independent parallel transportation through the parallel connecting block 2. This avoids crossflow or interference of media from different channels at the connection end, ensuring the independence and stability of media transportation in scenarios such as "water inlet + water return" and "two-way water inlet". This corresponding layout eliminates the need for additional adapter structures, simplifying the docking process between the dual-channel liquid distribution block 1 and the parallel connecting block 2, and improving the accuracy and efficiency of assembly.

[0055] The design of having two or more rows of fourth-path interfaces 22 along the length direction is compatible with the aforementioned "each parallel connection block 2 can simultaneously connect two or more sets of paths". Without significantly increasing the volume of the parallel connection block 2, it greatly increases the number of interfaces and branch expansion capabilities, meeting the parallel connection needs of more component liquid blocks 1 and adapting to the needs of large multi-station production lines and complex automated equipment for multi-branch media supply. The multi-row arrangement fully utilizes the longitudinal space of the parallel connection block 2, making the structure more compact and space utilization higher, avoiding the problem of insufficient installation space caused by simply increasing the length. At the same time, the orderly multi-row, multi-group arrangement allows the connecting pipes of each component liquid block 1 to be neatly arranged in rows and groups, reducing pipe crossing and tangling. This not only improves the overall neatness of the layout but also facilitates later maintenance of the liquid block 1 corresponding to a single set or row of interfaces, reducing the difficulty of maintenance operations.

[0056] According to one embodiment of this application, such as Figure 3As shown, the modular liquid distribution assembly also includes a pipe connector 3, a plug 4, and a connecting elbow 5; wherein, the pipe connector 3 is used to connect the liquid passage to an external pipe; the plug 4 is used to seal the end opening of the liquid passage; and the connecting elbow 5 is connected to the branch interface 113.

[0057] like Figure 3 and Figure 4 As shown, two pipe connectors 3 are located at the right end of the modular liquid distribution assembly, and two plugs 4 are located at the left end of the modular liquid distribution assembly. In some embodiments, the above arrangement can be adjusted, such as: the two pipe connectors 3 can be located at the left end of the modular liquid distribution assembly, and the two plugs 4 can be located at the right end of the modular liquid distribution assembly; or, a pipe connector 3 and a plug 4 can be set at the left end of the modular liquid distribution assembly, and a pipe connector 3 and a plug 4 can also be set at the right end of the modular liquid distribution assembly (and the two pipe connectors 3 are not on the same main passage, and the same applies to the two plugs 4); to adapt to different liquid circuit installation requirements.

[0058] And, as Figure 3 and Figure 4 As shown, one of the two pipe joints 3 can be a water inlet and the other a water return joint to form multiple sets of circulating liquid circuits (9 sets in the figure); when only unidirectional liquid supply is required and no return liquid is needed, both of the two pipe joints 3 can be water inlet interfaces, in which case unidirectional liquid supply can be provided to 18 positions at the same time.

[0059] Pipe connector 3 provides a standardized adaptation solution for connecting the liquid passage to external pipelines, solving the problem of inconvenience in directly connecting external pipelines of different specifications to the liquid passage. The standardized pipe connector 3 is compatible with common external pipeline interface types, quickly achieving a stable connection between the liquid passage and the external main pipeline and workstation pipelines, improving the convenience and versatility of the connection, while ensuring the sealing performance of the connection parts and reducing the risk of media leakage.

[0060] The plug 4 enables flexible sealing of the end opening of the liquid passage. When the liquid passage does not need to be extended or one end interface is not used temporarily (such as when the parallel connection block 2 is only connected to the main medium pipeline at one end, and the third passage interface 21 at the other end is blocked), the opening can be directly sealed by the plug 4 to prevent medium leakage and impurities from entering. This simplifies the assembly process and retains the expansion capability of the liquid passage. When the pipeline needs to be extended in the future, the plug 4 can be directly removed without modifying the liquid passage itself.

[0061] By connecting elbow 5, the direction and angle of the branch pipeline can be flexibly adjusted, avoiding interference between the branch pipeline and other components and pipelines. Especially in scenarios with multiple rows and sets of fourth passage interfaces 22, the neat pipeline routing can further improve the overall layout neatness. According to one embodiment of this application, such as Figure 1 and Figure 5 As shown, the first end of the liquid distribution block body 11 is also provided with a sealing groove 115, which is located around the first passage interface 111. The liquid distribution block 1 also includes a sealing element 12 disposed in the sealing groove 115, which is used to improve the sealing performance at the connection between two adjacent liquid distribution blocks 1. The sealing groove 115 can be an annular groove, and correspondingly, the sealing element 12 can be an annular element.

[0062] The combined structure of the sealing groove 115 and the sealing element 12 can solve the problem of media leakage caused by assembly gaps at the connection between two adjacent liquid distribution blocks 1. Media such as cutting fluid and coolant may be under pressure during transportation. Traditional connection methods without sealing structures are prone to media leakage, which not only wastes resources but may also affect the operating environment and safety of the equipment. After the sealing element 12 is embedded in the sealing groove 115 around the first passage interface 111, it can be squeezed and filled in the connection gap when adjacent liquid distribution blocks 1 are joined, forming a reliable sealing interface. This effectively prevents the media from overflowing from the connection, ensuring the sealing and stability of media transportation, and is suitable for various working conditions such as high pressure and vibration.

[0063] The sealing groove 115 provides a stable installation and positioning space for the seal 12, preventing displacement or detachment during assembly or use and ensuring the continuity of the sealing effect. Simultaneously, this sealing structure design does not increase the connection complexity between the liquid distribution blocks 1, and does not affect the quick docking of the first passage interface 111 and the second passage interface 112, retaining the core advantages of the modular liquid distribution assembly: convenient assembly and high efficiency. The detachable design of the seal 12 also facilitates later maintenance. When the seal 12 ages or is damaged, it can be directly removed from the sealing groove 115 for replacement without disassembling the liquid distribution block body 11 or the entire pipeline, reducing maintenance difficulty and cost, and further improving the economic efficiency of the assembly.

[0064] According to one embodiment of this application, such as Figure 2 As shown, the first and second ends of the liquid separator body 11 extend along the width direction of the liquid separator body 11 and form a connecting lug 116; a connecting hole 117 is provided on the connecting lug 116.

[0065] The combination of "connecting hole 117 + connecting screw 6" at the connecting lug 116 solves the problem of loose connection between adjacent liquid distribution blocks 1. During media transportation, pressure fluctuations in the pipeline or vibrations generated by equipment operation may cause displacement or loosening of the simply plugged-in liquid distribution blocks 1, affecting the stability and sealing of media transportation. By fastening the connecting lugs 116 of adjacent liquid distribution blocks 1 through the connecting hole 117 with the connecting screw 6, a rigid connection structure is formed, which can firmly lock the relative position of the liquid distribution blocks 1, prevent displacement or loosening, ensure the unobstructed flow of liquid and the sealing effect of the sealing structure, and is suitable for complex working conditions such as high pressure and high vibration.

[0066] The design of the connecting lug 116 extending along the width direction fully utilizes the width space of the main body 11 of the liquid distribution block, making the connection point distribution more balanced and the force more uniform, further improving the connection stability. At the same time, this connection structure does not change the core advantages of the modular liquid distribution assembly; during assembly, it only requires tightening with the connecting screws 6, making the operation simple and requiring no complex tools or professional skills, thus balancing connection reliability and assembly convenience. During disassembly and maintenance, only the corresponding connecting screws 6 need to be unscrewed to separate a single liquid distribution block 1, without affecting the normal operation of other liquid distribution blocks 1, reducing maintenance difficulty and downtime. This standardized connection structure also works synergistically with the sealing structure to ensure a tight fit between the mating surfaces of adjacent liquid distribution blocks 1, providing structural support for the function of the sealing element 12, further improving the sealing performance of the connection and the overall operational reliability.

[0067] In some embodiments, in addition to the aforementioned connection method of "connecting hole 117 + connecting screw 6", clamps or other methods can also be used to achieve quick connection of adjacent liquid distribution blocks 1.

[0068] The modular liquid distribution assembly provided in this application embodiment allows the liquid distribution block 1 to be quickly connected using connecting screws 6 to expand the number of branch interfaces 113. When the modular liquid distribution assembly needs to be expanded during use, it does not need to be completely disassembled; only the plug 4 needs to be removed for reassembly. In the process of expanding the number of branch interfaces 113, only connecting screws 6 and sealing rings are required. Compared to traditional liquid distribution blocks, which can only be expanded using threaded parts (requiring sealing with sealant or PTFE tape during the connection process, resulting in high construction difficulty, complex operation, high cost, and poor reliability and stability of sealant and PTFE tape), the modular liquid distribution assembly of this application embodiment is more efficient and reliable in expansion. The modular liquid distribution assembly can be easily connected in series and parallel, while traditional liquid distribution blocks, due to structural limitations, cannot quickly achieve series or parallel expansion.

[0069] A CNC machine tool according to a second aspect of this application includes the aforementioned modular liquid dispensing assembly.

[0070] The integrated application of modular liquid distribution components solves the problems of poor adaptability and inconvenient maintenance of traditional CNC machine tool liquid distribution systems. The number of machining stations and machining processes of CNC machine tools may be adjusted according to production needs. The modular liquid distribution components can flexibly adapt to the media distribution needs of different processing scenarios by increasing or decreasing the number of liquid distribution blocks and switching between dual-channel modes (inlet + return water / two inlet channels). There is no need to customize a liquid distribution system for the machine tool, which reduces the equipment customization cost and modification difficulty.

[0071] The standardized connection structure and sealing design ensure a stable supply of cutting fluid and coolant during machine tool operation, preventing machining accuracy from being affected by media leakage or uneven distribution. Meanwhile, the convenient assembly and simple maintenance of the components reduce downtime for CNC machine tool maintenance and improve the continuous machining capability of the equipment. The multi-row, multi-group interface layout and orderly piping design also adapt to the complex internal spatial layout of CNC machine tools, avoiding piping interference that could affect the normal operation of moving parts, further ensuring the stability of the machining process.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
