Description

Technical Field

[0001] This utility model mainly relates to the field of water valve processing technology, specifically to a water valve core assembly mechanism. Background Technology

[0002] In many fields such as industrial production, municipal water supply, and household appliances, water valves are the core components for controlling the flow and flow regulation of fluids. Their performance stability and reliability directly affect the operating efficiency and safety of the entire fluid transport system. The valve core assembly, as the "heart" of the water valve, is composed of multiple precision parts such as the valve core, sealing ring, spring, and valve stem. Its assembly quality directly determines the sealing performance and service life of the water valve.

[0003] Currently, most small and medium-sized water valve manufacturers still rely on manual or semi-automatic equipment for valve core assembly. During manual assembly, operators need to manually position and assemble the valve core, sealing ring, and housing in sequence. This is not only labor-intensive and inefficient, but also prone to human error (such as misalignment of parts or uneven pressing of sealing rings), which makes it difficult to guarantee assembly accuracy and leads to quality problems such as water valve leakage, increasing product rework rate and production costs. In common semi-automatic assembly lines, sealing ring installation, oiling, and valve core pressing are usually three independent workstations, with manual or robotic arms transferring workpieces between workstations. This results in long cycle times, large equipment footprint, and increased cumulative errors due to multiple positioning. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It primarily offers a water valve core assembly mechanism to solve the problems mentioned in the background section. In most small and medium-sized water valve enterprises, manual or semi-automatic assembly of valve core components is the primary method used. Manual assembly is labor-intensive, inefficient, and prone to errors leading to insufficient precision, valve leakage, and increased costs. While semi-automatic equipment reduces manpower, the processes are fragmented and poorly connected, requiring manual transfer, resulting in insufficient production continuity and difficulty in meeting large-volume production demands.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A water valve core assembly mechanism includes a housing, a valve core, and a shell. The lower part of the housing is provided with a pushing component, and the upper part of the housing is provided with a supporting component, a pressing component, and an installation component.

[0006] The mounting assembly includes a base plate, a third cylinder, and a guide tube. A movable rod is slidably mounted inside the guide tube. One end of the movable rod is connected to the telescopic end of the third cylinder. The guide tube has a flow channel and an annular groove inside. The end of the flow channel away from the mounting block is connected to the annular groove, and the end of the flow channel near the mounting block is provided with an oil inlet. The end of the guide tube away from the mounting block has annularly distributed oil drain holes, and each oil drain hole is connected to the annular groove.

[0007] More preferably, a slide rail and a mounting bracket are installed on the base plate, a second cylinder is provided on the mounting bracket, a support plate is slidably installed on the slide rail via a slider, the telescopic end of the second cylinder is connected to the support plate, a mounting block is installed on the support plate, a third cylinder is installed on one side of the mounting block, a guide tube is installed on the other side, and a sealing element is sleeved on the moving rod.

[0008] More preferably, the pushing assembly includes an electric push rod installed on the inner wall of the housing, an mounting plate installed on the electric push rod, first slide rods symmetrically distributed on the mounting plate, a slide plate slidably installed on the outer wall of the first slide rods, the telescopic end of the electric push rod being connected to the slide plate, and an installation fixture installed on the slide plate.

[0009] More preferably, the support assembly includes a base installed on the inner wall of the housing, on which a support fixture and symmetrically distributed limiting rods are installed. Both the support fixture and the base have holes adapted to the installation fixture, allowing the installation fixture to move up and down within the holes. The support fixture has round holes on both sides and at its rear end, allowing the installation assembly to drive the sealing element fitted on it through the round holes to complete the installation of the sealing element. The front end of the support fixture has a cavity, and an infrared distance sensor is provided at its front end.

[0010] More preferably, the pressing assembly includes support legs installed on the inner wall of the housing, with a fixing plate installed on the top of each support leg. There are four support legs in total, which are respectively installed at the four bottom corners of the fixing plate. A first cylinder is installed through the top center of the fixing plate, and symmetrically distributed second slide rods are slidably installed through the top of the first cylinder. A pressure plate is installed at the bottom of the second slide rod. The telescopic end of the first cylinder is connected to the pressure plate. A pressure block is installed on the pressure plate through a pressure sensor. A U-shaped plate is installed at the top of the second slide rod.

[0011] More preferably, the support component is disposed inside the lower part of the pressing component, the pushing component is disposed below the support component, and there are three mounting components in total, with the three mounting components located on both sides and the rear of the support component respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This water valve core assembly mechanism, through the push component, support component, pressing component, and installation component, delivers lubricating oil to the seal fitted on the moving rod during assembly. This is achieved through the cooperation of the guide tube's flow channel, annular groove, and oil drain hole, eliminating the need for manual oiling. This simplifies operation while ensuring uniform oiling to avoid affecting the sealing effect. Furthermore, the multi-component collaboration—using the electric push rod of the push component to move the valve core, the cylinder drive structure of the installation component to assemble the seal, and the pressing component to automatically press the housing to prevent displacement—achieves automated assembly from oiling to pressing, reducing manual intervention. Compared to traditional processing methods, it eliminates the need for manual adjustment of component positions or pressing operations, reducing labor costs and improving assembly efficiency.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Please refer to the appendix carefully. Figure 1-9 The water valve core assembly mechanism includes a housing 1, a valve core 7, and a shell 8. The lower part of the housing 1 is provided with a pushing component 2, and the upper part of the housing 1 is provided with a supporting component 3, a pressing component 4, and an installation component 5.

[0019] Mounting assembly 5 includes a base plate 501, a third cylinder 508, and a guide tube 509. A moving rod 5010 is slidably mounted inside the guide tube 509. One end of the moving rod 5010 is connected to the telescopic end of the third cylinder 508. A flow channel 5011 and an annular groove 5012 are provided inside the guide tube 509. The end of the flow channel 5011 away from the mounting block 507 is connected to the annular groove 5012. An oil inlet is provided at the end of the flow channel 5011 near the mounting block 507. An annularly distributed oil drain holes 5013 are provided at the end of the guide tube 509 away from the mounting block 507, and each oil drain hole 5013 is connected to the annular groove 5012.

[0020] In this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, a slide rail 502 and a mounting bracket 503 are mounted on the base plate 501. A second cylinder 504 is mounted on the mounting bracket 503. A support plate 506 is slidably mounted on the slide rail 502 via a slider 505. The telescopic end of the second cylinder 504 is connected to the support plate 506. A mounting block 507 is mounted on the support plate 506. A third cylinder 508 is mounted on one side of the mounting block 507, and a guide tube 509 is mounted on the other side. A sealing element 6 is fitted onto the moving rod 5010. When the third cylinder 508 is activated, it can... The slider 505, support plate 506, mounting block 507, third cylinder 508, guide tube 509, and moving rod 5010 move left and right as a whole. During the water valve assembly process, this structure can drive the sealing element 6 sleeved on the moving rod 5010 to approach the valve core 7, thereby completing the assembly operation. At the same time, the sliding cooperation of the slider 505 on the slide rail 502 can improve the stability of the overall structure of support plate 506, mounting block 507, third cylinder 508, guide tube 509, and moving rod 5010 when moving.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the pushing component 2 includes an electric push rod 201 installed on the inner wall of the housing 1. An installation plate 202 is installed on the electric push rod 201. A first slide rod 203 is symmetrically distributed on the installation plate 202. A slide plate 204 is slidably installed on the outer wall of the first slide rod 203. The telescopic end of the electric push rod 201 is connected to the slide plate 204. An installation fixture 205 is installed on the slide plate 204. The top structure of the installation fixture 205 is adapted to the bottom structure of the valve core 7. When the valve core 7 is placed on top of the installation fixture 205, the installation fixture 205 can limit the valve core 7, ensuring that the valve core 7 and the housing 8 can be installed stably and accurately. When the electric push rod 201 is started, its telescopic end passes through the hole on the installation plate 202, which can drive the slide plate 204, the installation fixture 205 and the valve core 7 to move up and down as a whole, thereby completing the installation operation. When the slide plate 204 moves up and down, it slides along the first slide rod 203, which can improve the stability of the installation fixture 205 and the valve core 7 during the up and down movement.

[0022] In this embodiment, as Figure 1 and Figure 3As shown, the support assembly 3 includes a base 301 installed on the inner wall of the housing 1. The base 301 is equipped with a support fixture 302 and symmetrically distributed limiting rods 303. Both the support fixture 302 and the base 301 have holes adapted to the installation fixture 205, allowing the installation fixture 205 to move up and down within the holes. The support fixture 302 has round holes on both sides and at the rear end, allowing the installation assembly 5 to drive the sealing element 6 fitted on it through the round holes to complete the installation of the sealing element 6. The front end of the support fixture 302 has a cavity, and an infrared distance sensor is installed at its front end. The support fixture 302 is used to support the housing 8, and the limiting rods 303 are used to position the housing 8. During the water valve assembly process, the round holes at the two extended ends of the housing 8 can be aligned with the limiting rods 303, so that the limiting rods 303 can be inserted into the corresponding round holes. Since the outer diameter of the limiting rod 303 matches the inner diameter of the round hole, the housing 8 can be accurately and stably positioned.

[0023] In this embodiment, as Figure 1 and Figure 4 As shown, the pressing assembly 4 includes support legs 401 installed on the inner wall of the housing 1. A fixing plate 402 is installed on the top of the support legs 401. There are four support legs 401, which are respectively installed at the four bottom corners of the fixing plate 402. A first cylinder 403 is installed through the top center of the fixing plate 402, and a symmetrically distributed second slide rod 404 is slidably installed through the top of the cylinder 402. A pressure plate 405 is installed at the bottom end of the second slide rod 404. The telescopic end of the first cylinder 403 is connected to the pressure plate 405. A pressure block is installed on the pressure plate 405 through a pressure sensor. A U-shaped plate is installed at the top of the second slide rod 404. When the first cylinder 403 is started, it can drive the pressure plate 405 to move up and down. The second slide rod 404 can improve the stability of the pressure plate 405 when it moves. During the water valve assembly process, it can drive the pressure plate 405 and the pressure block on it to move downward, forming a pressing effect on the housing 8, thereby improving the stability during assembly.

[0024] In this embodiment, as Figure 1 As shown, the support component 3 is located inside the lower part of the pressing component 4, the pushing component 2 is located below the support component 3, and there are three mounting components 5, which are located on both sides and behind the support component 3 respectively. During the water valve assembly process, through the coordinated action of the three mounting components 5, the three seals 6 can be moved to the corresponding installation position of the valve core 7, thereby ensuring the accuracy of the installation position of each seal 6 in subsequent assembly operations.

[0025] The specific operating procedure of this utility is as follows: First, place the valve core 7 to be assembled on the top of the mounting fixture 205 of the push assembly 2. Since the top structure of the mounting fixture 205 is compatible with the bottom structure of the valve core 7, the valve core 7 is limited.

[0026] Next, the water valve housing 8 to be assembled is placed on the support fixture 302 of the support assembly 3. The two extended ends of the housing 8 are aligned with the limiting rods 303 symmetrically distributed next to the support fixture 302, so that the limiting rods 303 are inserted into the corresponding round holes, thus completing the positioning of the housing 8.

[0027] Next, the three seals 6 are respectively fitted onto the moving rods 5010 of the three mounting components 5. Through an external metering oil pump, inlet pipe and flow solenoid valve, lubricating oil is delivered from the oil inlet of the guide pipe 509 near the mounting block 507 (metered delivery by metering oil pump and flow solenoid valve) to the guide channel 5011. After the lubricating oil flows into the annular groove 5012 through the guide channel 5011, it is evenly discharged through the annularly distributed oil drain holes 5013 at the end of the guide pipe 509 away from the mounting block 507, thus completing the oiling of the seals 6. After the oiling is completed, the oil delivery is stopped to provide lubrication for subsequent assembly.

[0028] Next, the electric push rod 201 of the push assembly 2 is activated, and its telescopic end drives the slide plate 204 to slide down along the first slide rod 203, thereby driving the installation fixture 205 and the valve core 7 to move down to the preset position (sensed by an infrared distance sensor).

[0029] Next, the second cylinder 504 of the three mounting components 5 is activated, and its telescopic end pushes the support plate 506 to slide along the slide rail 502, which drives the mounting block 507, the third cylinder 508, the guide tube 509 and the moving rod 5010 with the seal 6 to move closer to the valve core 7. After the seal 6 and the valve core 7 are aligned, the third cylinder 508 is activated, which drives the moving rod 5010 to slide inward along the guide tube 509 and retract into the guide tube 509. At this time, the arc-shaped structure on the top of the mounting fixture 205 supports the seal 6.

[0030] Simultaneously, the first cylinder 403 of the pressing component 4 is activated, and its telescopic end drives the pressure plate 405 to move downward along the second slide bar 404 until the pressure block at the bottom of the pressure plate 405 is in close contact with the housing 8 on the support fixture 302 (the pressure sensor on the pressure plate 405 senses the pressure, and stops pressing when the preset pressure value is reached), forming a stable clamping on the housing 8 to prevent the housing 8 from shifting during assembly.

[0031] Next, the electric push rod 201 of the push assembly 2 is activated, which drives the slide plate 204, the mounting fixture 205, the seal 6 and the valve core 7 to move upward, so that the valve core 7 and the seal 6 are inserted into the corresponding mounting cavity of the housing 8. After the valve core 7 is fully connected with the housing 8, the electric push rod 201 stops working, and the overall assembly of the water valve is completed.

[0032] Next, the first cylinder 403 of the pressing component 4 is controlled to move the pressure plate 405 upward and reset, and the electric push rod 201 of the component 2 is pushed to move the installation fixture 205 downward and reset. All components are restored to their initial state, ready for the next assembly. Then, the assembled water valve is removed from the support fixture 302 by manual or external material handling mechanism, and the entire water valve assembly process is completed.

[0033] It should be noted that the cylinder control process, the air supply structure adapted to the cylinder control, and the control valve assembly involved in this utility model are all mature existing technologies disclosed in the field. Their technical principles, assembly relationships, and workflows are well known to those skilled in the art, and therefore will not be described in detail in this specification. Furthermore, the pressure sensor, infrared distance sensor, electric push rod 201, first cylinder 403, second cylinder 504, and third cylinder 508 in this utility model are all electrically connected to the control system. The control system's control methods for the pressure sensor, infrared distance sensor, electric push rod 201, first cylinder 403, second cylinder 504, and third cylinder 508, as well as the specific structures of the sensors and other components themselves, are well-known and mature existing technologies in this field. Therefore, this specification will not elaborate on them further.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
