Description

Technical Field

[0001] This invention relates to the field of water meter housing assembly technology, and more specifically, to a fully automatic pressure relief device for water meter housings. Background Technology

[0002] The water meter casing is a protective structure surrounding the water meter's metering unit. It is designed to protect the delicate mechanical or electronic metering components inside the water meter from external environmental factors such as physical damage, corrosion, and contaminant intrusion.

[0003] During the manufacturing process of a water meter casing, a middle ring needs to be installed inside the casing. In existing technologies, the installation of the middle ring is generally done manually by placing it inside the water meter casing, which requires tilting the middle ring and then pressing it down. This method has low automation and is inefficient. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a fully automatic and efficient water meter casing middle ring pressure release device and pressure release method.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] In a first aspect, this application provides a fully automatic pressure relief device for a water meter casing, comprising:

[0007] Machine tool;

[0008] The material discharge mechanism, installed on the machine base, has a discharge port for storing several middle rings and discharging them one by one from the discharge port;

[0009] The clamping pressure ring mechanism is installed on the machine base and located on one side of the discharge mechanism. It has a first positioning component for fixing the water meter housing and a clamping component for vertically clamping and pressing the middle ring inside the water meter housing on the first positioning component.

[0010] The transfer mechanism is installed on the machine platform and is located opposite to the discharge mechanism and the clamping pressure ring mechanism. It is used to take out the middle ring of the discharge port and put it into the water meter housing on the first positioning component.

[0011] The tilting mechanism, installed above the machine base, has a movable lever. Moving the lever will tilt the middle ring inside the water meter housing after the middle ring has been clamped down.

[0012] The pressing mechanism, installed on the machine base and located on the side of the transfer mechanism away from the clamping pressure ring mechanism, is used to press the middle ring inside the water meter casing downwards after the middle ring has been tilted; and

[0013] The transport mechanism is installed on the machine platform and is located in the opposite position to the clamping and pressing mechanism. It is used to remove the water meter shell from the first positioning part and transport it in sequence to the bottom of the tilting mechanism and the pressing mechanism.

[0014] Secondly, this application provides a method for releasing pressure in the middle ring, the steps of which are as follows:

[0015] S1. Place the water meter casing on the first positioning component, and use the transfer mechanism to remove the middle ring inside the discharge port and place it into the water meter casing on the first positioning component.

[0016] S2. The middle ring inside the water meter casing on the first positioning part is vertically clamped and pressed down by the clamping component on the clamping pressure ring mechanism;

[0017] S3. The transport mechanism removes the water meter casing from the first positioning component and moves it below the tilting mechanism. At this time, the lever is located on one side of the central ring axis.

[0018] S4. Move the lever to press against the upper half of the center ring to tilt the center ring down.

[0019] S5. The transport mechanism then transports the water meter casing to the pressing mechanism, which presses the middle ring into the water meter casing.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The feeding mechanism automatically discharges the middle rings one by one from the outlet; the transfer mechanism transfers the middle rings from the outlet and places them into the water meter casing on the first positioning component, achieving automatic ring placement; the clamping assembly clamps and presses the middle rings into the water meter casing, vertically securing them inside the casing for precise subsequent tilting; the tilting mechanism moves a lever to tilt the vertically positioned middle rings, resulting in an inclined or horizontal position, which, in conjunction with the subsequent pressing mechanism, horizontally presses the middle rings together; the transport mechanism sequentially transports the water meter casing from the first positioning component, the tilting mechanism, and the pressing mechanism, achieving fully automated operation. This integrated system achieves automated assembly of the middle rings and the water meter casing, thereby improving operational efficiency. Attached Figure Description

[0039] During the manufacturing of a water meter casing, a middle ring needs to be installed inside. In existing technology, the installation of the middle ring is generally done manually, by placing it inside the casing and then tilting it before pressing it down. This process is slow and lacks automation. Specifically, during placement, the middle ring is inserted into the casing, and then fingers are used to tilt it, ensuring it is either horizontal or tilted. Because the inner edge of the opening at the top of the water meter casing is sharp, directly inserting a hand into the casing can easily cause cuts.

[0040] Based on this, in order to improve the problems of low automation, slow efficiency and insecurity in the existing technology, the embodiments of the present invention provide the following technical solutions.

[0041] refer to Figure 1-2In a first aspect, the present invention provides a fully automatic pressure release device for water meter casings, comprising: a machine base 1; a discharge mechanism 2, installed on the machine base 1, having a discharge port 21 for storing a plurality of middle rings 9 and discharging them one by one from the discharge port 21; a clamping and positive pressure ring mechanism 3, installed on the machine base 1 and located on one side of the discharge mechanism 2, having a first positioning member 31 for fixing the water meter casing 8 and a clamping assembly 32 for vertically clamping and pressing down the middle rings 9 inside the water meter casing 8 on the first positioning member 31; and a transfer mechanism 4, installed on the machine base 1 and located opposite to the discharge mechanism 2 and the clamping and positive pressure ring mechanism 3, for removing and releasing the middle rings 9 from the discharge port 21. The water meter housing 8 is inserted into the first positioning member 31; the tilting mechanism 5, installed above the machine base 1, has a movable lever 51, which moves to tilt the middle ring 9 inside the water meter housing 8 after it has been clamped and pressed down; the pressing mechanism 6, installed on the machine base 1 and located on the side of the transfer mechanism 4 away from the clamping and pressing mechanism 3, is used to press the middle ring 9 inside the water meter housing 8 downward after it has been tilted; and the transport mechanism 7, installed on the machine base 1 and located opposite to the clamping and pressing mechanism 6, is used to remove the water meter housing 8 from the first positioning member 31 and transport it sequentially to the area below the tilting mechanism 5 and onto the pressing mechanism 6. The tilting mechanism 5 is the component that tilts the middle ring 9 inside the water meter housing 8, for example, it can be a lever 51 cooperating with a driver.

[0042] Understandably, the machine base 1 serves as the supporting structure for the entire equipment, and can be, for example, a frame structure, a planar structure, a box structure, etc., but is not limited to these. The discharge mechanism is a component that stores and discharges the middle ring 9, and can be, for example, a component that combines the discharge port 21 and the storage section 25, but is not limited to these. The clamping and pressing ring mechanism 3 is a component that fixes the water meter housing 8 and vertically aligns and presses down the middle ring 9, and can be, for example, a component that combines the first positioning member 31 and the clamping assembly 32, but is not limited to these. The transfer mechanism 4 is a component that removes the middle ring 9 from the discharge mechanism 2 and transports it into the water meter housing 8 on the first positioning position, and can be, for example, a component that combines the first clamping member with multiple moving drive components with different driving directions, but is not limited to these. The tilting mechanism 5 is a component that tilts the vertically positioned middle ring 9 inside the water meter housing 8, and can be, for example, a component that combines the drive component and the toggle lever 51, but is not limited to these. The pressing mechanism 6 is a component that fixes the water meter housing 8 and presses the middle ring 9 downward, thereby moving the middle ring 9 horizontally to the correct position inside the water meter housing 8. For example, it can be a component that works in conjunction with the second positioning member 61 and the driving member, but is not limited to this. The conveying mechanism 7 is a component that can remove the water meter housing 8 from the second positioning member 61 and sequentially convey it to the area below the tilting mechanism 5 and onto the pressing mechanism 6. For example, it can be a component that works in conjunction with the second picking member 71 and multiple combined moving driving members in different directions, but is not limited to this. The water meter housing 8 on the first positioning member 31 and the water meter housing 8 on the second positioning member 61 can be picked up and placed manually or by a robot.

[0043] As can be seen from the above, during operation, the transfer mechanism 4 removes the middle ring 9 from the discharge port 21 and transfers it to the water meter housing 8 on the second positioning component 61. After being released, the middle ring 9 falls into the water meter housing 8. (Reference) Figure 6 Then, the clamping assembly 32 clamps the middle ring 9 upright and presses it down to keep it vertical. Next, the transport mechanism 7 moves the water meter casing 8 on the first positioning member 31 to below the tilting mechanism 5, so that the actuating lever 51 is positioned on one side of the middle ring 9. The movement of the actuating lever 51 pushes the middle ring 9 down. (Refer to...) Figure 7 At this point, the middle ring 9 is either horizontal or tilted. Finally, the transport mechanism 7 transports the water meter casing 8 to the pressing mechanism 6 for pressing, as shown in the reference. Figure 8 This ensures that the middle ring 9 is pressed horizontally into the correct position inside the water meter casing 8. The entire process requires no manual operation, improving automation and efficiency, avoiding hand injuries during manual operation, and guaranteeing safety.

[0044] refer to Figure 2-3In some embodiments, the discharge mechanism 2 further includes: a first support 22; mounted on the machine base 1; a base 23, mounted on the first support 22, the base 23 having an opening 24 at its top, the discharge port 21 being located on the side of the base 23 near the transfer mechanism 4 and communicating with the opening 24; and a storage section 25, mounted on the base 23, having a through groove 26 communicating with the opening 24, in which the middle ring 9 can be stacked.

[0045] Understandably, the first support 22 serves both to raise the height of the discharge port 21 and to support the entire discharge mechanism 2. It can be composed of one or more vertically arranged rods, or a vertical plate, but is not limited to these. The base 23 supports multiple stacked middle rings 9, and can be a block-shaped or disc-shaped structure, but is not limited to these. The opening 24 accommodates and limits the middle rings 9, and its size is adapted to the middle rings 9. The discharge port 21 provides space for the transfer mechanism 4 to retrieve the middle rings 9, and can be a flat square structure or a flat, outwardly expanding structure, but is not limited to these. The storage section 25 stores the stacked middle rings 9, and can be a structure formed by multiple vertical rods arranged in a ring or a structure with grooves on a cylinder, but is not limited to these.

[0046] With this configuration, multiple middle rings 9 can be stacked within the storage section 25. Since the storage section 25 is connected to the opening 24, and the opening 24 is connected to the discharge port 21, the middle rings 9 can fall from the opening to the discharge port 21, and the transfer mechanism 4 can then remove the middle rings 9 from the discharge port 21 for discharge. Due to gravity, after the bottom middle ring 9 is removed, the middle rings 9 in the storage section 25 will automatically fall back to the discharge port 21. This achieves the storage and discharge of the middle rings 9.

[0047] refer to Figure 2 and Figure 4 In some embodiments, the clamping assembly 32 includes: a second bracket 321, mounted on the machine base 1, and having a first fixing plate 322 located above the first positioning member 31; a clamping member 324, mounted above the first positioning member 31, for clamping the middle ring 9 inside the water meter housing 8 on the first positioning member 31; and a clamping driver 323, mounted on the first fixing plate 322, and connected to the clamping member 324 to drive the clamping member 324 to move downward, so that the clamping member 324 clamps the middle ring 9 and presses it down.

[0048] Understandably, the second bracket 321 is a component for lifting the pressure clamping driver 323. For example, it can be a single or multiple vertical rods working in conjunction with the first fixing plate 322, or a combination structure of a single or multiple vertical plates working in conjunction with the first fixing plate 322, etc., but is not limited to these. The first fixing plate 322 is a component for fixing the pressure clamping driver 323. For example, it can be a square plate structure or a disc structure, etc., but is not limited to these. The clamping member 324 is a component for clamping the middle ring 9. For example, it can be a pneumatic clamp, hydraulic clamp, electric clamp, mechanical clamp, etc., but is not limited to these. The pressure clamping driver 323 is a component that drives the clamping member 324 downwards, thereby clamping the middle ring 9 inside the water meter housing 8. For example, it can be a cylinder, hydraulic cylinder, electric push rod, linear motor, etc., but is not limited to these. The first positioning member 31 is a component for fixing the water meter housing 8. For example, it can be a component with a groove adapted to the water meter housing 8, or it can be a pneumatic gripper, electric gripper, magnetic gripper, etc., but is not limited to these.

[0049] With this configuration, the first positioning component 31 can fix the water meter housing 8. The clamping component 324 is moved down by the clamping driver 323 to clamp and align the middle ring 9. The clamping driver 323 also moves the clamping component 324 down to lock the middle ring 9 inside the water meter housing 8, ensuring that the middle ring 9 is in a vertical position. This facilitates subsequent use with the tilting mechanism 5.

[0050] Optionally, in some embodiments, the clamping position of the clamping member 324 is on the same vertical line as the center of the water meter housing 8 on the first positioning member 31, so that when the clamping member 324 clamps the middle ring 9, the middle ring 9 is located at the center of the water meter housing 8.

[0051] Understandably, the clamping position of the clamping member 324 relative to the center position of the water meter housing 8 can be adjusted by modifying the positions of the clamping member 324 and the first positioning member 31. By setting the position of the first positioning member 31, the position of the water meter housing 8 is locked, thus aligning the clamping position of the clamping member 324 with the center position of the water meter housing 8. Generally, the size of the middle ring 9 is designed to match the size of the water meter housing 8; that is, the inner diameter of the water meter housing 8 is slightly larger than the outer diameter of the middle ring 9. Thus, when the middle ring 9 is inside the water meter housing 8, the outer ring of the middle ring 9 and the inner ring of the water meter housing 8 share a center line. In other words, when the sizes are compatible, the middle ring 9 does not need to be repositioned; simply aligning and pressing it down will secure it in the center of the water meter housing 8.

[0052] With this configuration, the clamping member 324 can not only vertically align the center ring 9, but also adjust its horizontal position, ensuring that the center ring 9 is centered inside the water meter housing 8. This allows for positional adjustments even with slight deviations in the center ring 9's placement, guaranteeing its stability.

[0053] refer to Figure 2 and Figure 4 In some embodiments, the transfer mechanism 4 includes: a first material-picking member 41, used to clamp the middle ring 9 of the material outlet 21 and to loosen the middle ring 9 and place it into the water meter housing 8 on the first positioning member 31; a first telescopic member 42, connected to the first material-picking member 41, thereby driving the first material-picking member 41 to move towards the material outlet 21 and / or the first positioning member 31; and a first linear module 43, installed on the machine base 1 and connected to the first telescopic member 42, thereby driving the first material-picking member 41 to move back and forth repeatedly between the material outlet 21 and the first positioning member 31.

[0054] Understandably, the first material-grabbing component 41 is a component that grips and releases the middle ring 9 inside the discharge port 21 and places it into the water meter housing 8. It can be, for example, a pneumatic gripper, an electric gripper, a magnetic gripper, etc., but is not limited to these. The first telescopic component 42 is a component that can drive the first material-grabbing component 41 to extend or retract. It can be, for example, a cylinder, a hydraulic cylinder, an electric push rod, a linear motor, etc., but is not limited to these. The first linear module 43 is a component that drives the first telescopic component 42, thereby driving the first material-grabbing component 41 to move between the discharge port 21 and the first positioning component 31. It can be, for example, a cylinder with a guide rail structure, a ball screw structure, a gear and rack linear transmission structure, a belt drive structure, etc., but is not limited to these.

[0055] With this configuration, the first linear module 43 drives the first telescopic component 42, which in turn drives the first picking component 41, to move to the position opposite to the outlet 21. Then, the first telescopic component 42 drives the first picking component 41 to move closer to the outlet 21, where it grips the middle ring 9. The first telescopic component 42 then drives the first picking component 41 to retract and reset. At this point, the first linear module 43 again drives the first telescopic component 42, which in turn drives the first picking component 41, to move to the position opposite to the first positioning component 31. The first telescopic component 42 then drives the first picking component 41 closer to the first positioning component 31, releasing the middle ring 9 and placing it into the water meter housing 8 on the first positioning component 31. The first telescopic component 42 then drives the first gripping component to retract and reset. This process is repeated. This achieves automated placement of the middle ring 9 into the water meter housing 8, which is more precise than manual placement.

[0056] refer to Figure 2 and Figure 4 In some embodiments, the tilting mechanism 5 further includes: a fixed frame 52, installed between the clamping pressure ring mechanism 3 and the pressing mechanism 6; and a tilting driver 53, installed on the fixed frame 52 and connected to the lever 51, thereby driving the lever 51 to move and tilt the middle ring 9.

[0057] Understandably, the fixing frame 52 is a component that fixes the tilting actuator 53. For example, it can be a horizontal bar or plate connected to the clamping pressure ring mechanism 3 and the pressing mechanism 6, or it can be directly mounted on the machine base 1, but it is not limited to these. The tilting actuator 53 is a component that can drive the actuating lever 51 to move horizontally, or it can be a component that drives the actuating lever 51 to move horizontally and vertically in combination. For example, it can be a cylinder, an electric push rod, a linear motor, etc.; or it can be a combination of two cylinders, electric push rods, linear motors, etc. The actuating lever 51 is a component that pushes down the vertical middle ring 9 that is stuck in the water meter housing 8. For example, it can be a rod-shaped structure or a square strip structure, but it is not limited to these.

[0058] With this configuration, when the water meter casing 8 is below the tilting mechanism 5, the tilting driver 53 can drive the actuating rod 51 to move towards the center ring 9, thereby pushing the center ring 9 down. Alternatively, the tilting driver 53 can drive the actuating rod 51 down to a suitable position, and then drive the actuating rod 51 to move horizontally to push the center ring 9 down. This allows for automatic tilting of the center ring 9, facilitating the subsequent pressing of the center ring 9 by the pressing mechanism 6.

[0059] Optionally, in some embodiments, the actuating lever 51 is vertically downward. During horizontal movement, the actuating lever 51 needs to push down the center ring 9, and during this process, the top height of the center ring 9 continuously decreases. The vertically positioned actuating lever 51 ensures continuous contact with the center ring 9, thereby guaranteeing that the center ring 9 can be pushed down to the required tilt angle.

[0060] refer to Figure 2 and Figure 5 In some embodiments, the pressing mechanism 6 includes: a third bracket 62, mounted on the machine base 1, having a second fixing plate 621 located above the machine base 1; a second positioning member 61, mounted on the machine base 1 and located below the second fixing plate 621, for fixing the water meter housing 8 after the middle ring 9 is tilted; and a pressing driver 63, mounted on the second fixing plate 621, with a pressing member 64 installed at its output end. The pressing driver 63 drives the pressing member 64 to move down and press the middle ring 9 inside the water meter housing 8 on the second positioning plate.

[0061] Understandably, the third bracket 62 is a component for lifting the pressure-closing actuator 63. For example, it could be a single or multiple vertical rods working in conjunction with the first fixing plate 322, or a combination of a single or multiple vertical plates working in conjunction with the second fixing plate 621, etc., but is not limited to these. The second fixing plate 621 is a component for fixing the pressure-closing actuator 63. For example, it could be a square plate structure or a disc structure, etc., but is not limited to these. The second positioning component 61 is a component for fixing the water meter housing 8. For example, it could be a component with a groove adapted to the water meter housing 8, or it could be a pneumatic gripper, an electric gripper, a magnetic gripper, etc., but is not limited to these. The pressure-closing actuator 63 is a component that drives the pressing component 64 downwards, thereby pressing the middle ring 9 into the correct position inside the water meter housing 8. For example, it could be a cylinder, a hydraulic cylinder, an electric push rod, a linear motor, etc., but is not limited to these. The pressing component 64 is a component that abuts against and presses down the middle ring 9. For example, it could be a block-shaped or disc-shaped structure, but is not limited to these.

[0062] With this configuration, the second positioning component 61 fixes the middle ring 9 when it is pushed into the water meter housing 8, and the pressing driver 63 drives the pressing component 64 to move down and extend into the water meter housing 8, thereby pressing the middle ring 9 into the accurate position of the water meter housing 8. This achieves automatic pressing.

[0063] refer to Figure 2 and Figure 5 In some embodiments, the conveying mechanism 7 includes: a second material-grabbing component 71 for gripping the water meter casing 8; a lifting device 72 connected to the second material-grabbing component 71, thereby driving the second material-grabbing component 71 to move up and down; a second telescopic device 73 connected to the lifting device 72, thereby driving the second material-grabbing component 71 to move towards the first positioning and / or pressing mechanism 6; and a second linear module 74 installed on the machine base 1 and connected to the second telescopic device 73, thereby driving the second material-grabbing component 71 to move repeatedly between the first positioning component 31 and the pressing mechanism 6.

[0064] Understandably, the second picking component 71 is the part that grips the water meter casing 8, and can be, for example, a pneumatic gripper, an electric gripper, a magnetic gripper, etc., but is not limited to these. The lifting device 72 is the part that drives the second picking component 71 to move up and down, and can be, for example, a cylinder, a hydraulic cylinder, an electric push rod, a linear motor, etc., but is not limited to these. The second telescopic component is the part that can drive the second picking component 71 to extend or retract, and can also be, for example, a cylinder, a hydraulic cylinder, an electric push rod, a linear motor, etc., but is not limited to these. The second linear module 74 is the part that drives the second picking component 71 to move between the first positioning component 31, the tilting mechanism 5, and the second positioning component 61, and can be, for example, a cylinder with a guide rail structure, a ball screw structure, a gear and rack linear transmission structure, a belt drive structure, etc., but is not limited to these.

[0065] With this configuration, the water meter casing 8, clamped and pressed on the first positioning member 31, is removed through the cooperation of the second linear module 74, the second telescopic member 73, the lifting member 72, and the second clamping member. It is then transported to below the tilting mechanism 5, causing the actuating lever 51 to be positioned on one side of the middle ring 9, thus tilting the middle ring 9. After the middle ring 9 is tilted, the water meter casing 8 is transported to the second positioning member 61 and pressed together by the pressing mechanism 6. This achieves automated transport of the water meter casing 8 between the clamping and pressing mechanism, the tilting mechanism 5, and the pressing mechanism 6.

[0066] Secondly, the present invention provides a method for releasing pressure on the middle ring 9, the steps of which are as follows:
