Description

Technical Field

[0001] The invention relates to the technical field of wet water meter assembly, and in particular to automated water meter water filling assembly and processing equipment. Background Art

[0002] The existing wet water meter production process adopts: the water inlet and outlet of the wet water meter are clamped with the water injection joint of the water injection equipment, and water is injected into the case of the watch with the movement installed without tightening the fixing ring, so as to discharge the air inside the case and the movement; after a certain period of water injection and exhaust, a sealing ring is manually placed on the water meter surface port, and then a glass is covered, and then the glass is manually controlled to move at different positions on the water meter surface port, so that the air under the glass is discharged by the water flow; it is observed by the naked eye whether there are still bubbles under the glass or the bubbles are smaller than the set value, and after manually placing the buffer pad while keeping the water injection state, the fixing ring is manually screwed on; for the water meter whose exhaust effect meets the requirements, the fixing ring is tightened according to the set torque using an electric tightening machine. Alternatively, the following methods can be used: manually install the movement, sealing ring, glass, buffer pad, and fastening ring of the wet water meter, and then use an electric tightening machine to tighten the fastening ring according to the set torque; clamp the water inlet and outlet of the water meter with the water injection joint of the water injection equipment, and inject water into the water meter with the tightened fastening ring according to the set time to exhaust the air. The movement dial part, sealing ring, and glass with the tightened fastening ring form a relatively closed cavity, and only a narrow gap between the plum blossom pointer shaft and the shaft hole at the bottom of the dial is connected to the inside of the meter body. In this way, it is difficult to achieve the set exhaust effect by injecting water into the cavity for a short time (less than one hour), and even the bubbles in the cavity cannot be discharged for a long time. Usually, there are large bubbles under the glass; inject The water meter that still has bubbles after the water is exhausted should be installed on a special air extraction and water injection equipment (the main mechanism is a U-shaped vacuum reflux pump) for secondary water injection and exhaust; place the water meter dial downward, clamp the inlet and outlet with joints, inject water through the water inlet of the water meter, and then pump water from the water outlet of the water meter. By pumping water at one end and injecting water at the other end of the water meter, the air in the dial cavity is gradually extracted; usually, in order to achieve a more ideal water extraction and exhaust effect, a special equipment only extracts 1 to 2 water meters at a time, and the single air extraction CT is greater than 40 seconds; manually observe and determine whether the bubbles on the dial of the wet water meter meet the set requirements. If they meet the requirements, loosen the water injection joint and take out the meter. If not, repeat the air extraction and water injection until it is qualified.

[0003] In the prior art, during the assembly and use of a wet water meter, water is manually injected into the water meter, which easily generates bubbles, takes a long time to assemble, and the sealing between the internal movement and the case is insufficient.

[0037] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0038] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the invention claimed for protection, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] like Figure 1-Figure 8 As shown, this embodiment proposes an automatic water meter water filling assembly processing equipment, including a water filling machine 1 and a water meter to be filled with water, the inner end of the water filling machine 1 is provided with a water meter mounting frame 6, the upper end of the water meter mounting frame 6 is provided with a water meter support frame 2, and also includes:

[0041] A water injection meter clamping assembly is used for water injection and clamping of a water meter to be injected. The water injection meter clamping assembly comprises a meter clamping joint 5 and a water injection rack 4 located at both ends of the water meter to be injected. The outer end of the water injection rack 4 at the right end is connected to the right water injection pipe 3, and the outer end of the water injection rack 4 at the left end is connected to a water meter rotation servo motor 9;

[0042] The water meter side rotation assembly is used to provide a certain rotation of the water meter to be filled, so as to facilitate a certain oblique angle between the glass located at the lower side of the fastening ring and the movement dial of the water meter to be filled, so as to facilitate the discharge of bubbles in the internal cavity of the water meter. The water meter filling assembly includes a glass orientation block 13 located at the front end of the water meter to be filled, an orientation block linkage arm 14 is provided at the outer end of the glass orientation block 13, and an orientation block rotating cylinder 15 is provided at the lower end of the orientation block linkage arm 14;

[0043] The fastening ring tightening assembly is used for fastening and sealing the water meter and the fastening ring after water filling is completed. The fastening ring tightening assembly includes two groups of fastening ring tightening plates 16 for wrapping the fastening ring. The upper ends of the two groups of fastening ring tightening plates 16 are provided with an annular groove 17, and the inner ends of the annular groove 17 are provided with a linkage spring 18. The upper ends of the two groups of fastening ring tightening plates 16 are provided with a tightening rotating cylinder 20.

[0044] During use, when the water meter to be filled is placed on the water meter mounting frame 6, the fastening ring at the upper end of the water meter to be filled is not completely tightened, and the glass in the fastening ring is in a movable state at this time. The water meter side rotation assembly drives the water meter to be filled to rotate to a certain extent. The directional block linkage arm 14 drives the glass directional block 13 to fit the edge of one side of the glass on the water meter to be filled under the rotation of the directional block rotating cylinder 15. At this time, the water injection pipe 3 injects water into the water meter to be filled, and the glass at the upper end of the movement is impacted by the water pressure, forming a V-shaped angle between the glass and the movement (the rotation of the glass is limited by the connection space between the fastening ring and the water meter), which facilitates the discharge of bubbles at the upper end of the water injection to the outer end of the meter housing, ensuring that the water inside the housing is filled (the overall rotation of the water meter is to fill the gap between the glass and the movement dial for drainage). , changed from a horizontal angle to an upward angle in the drainage direction, using the characteristics of gas density being lower than water and gas being on the top of water to accelerate the discharge of bubbles. Compared with the horizontal drainage of the water meter glass, it can greatly improve the efficiency of internal bubble discharge). After the bubbles are completely discharged outward, the glass directional block leaves the glass. At this time, the angle between the glass and the movement is released, and the water meter side rotation assembly is rotated to ensure that the glass at the upper end of the water meter is fitted with the upper end of the meter shell through the sealing ring. During this process, the water filling pipe continues to slowly inject water inward (slow water injection can ensure the stability of the internal water flow and will not generate bubbles again) until the fastening ring tightening assembly tightens the fastening ring at the upper end of the glass to the upper end of the meter shell, so that the cavity between the glass and the movement is completely filled with water to achieve sealing.

[0045] The water injection meter clamp assembly also includes an alignment clamp plate 7 and an alignment cylinder 8 located at the front and rear ends of the water meter to be injected. A positioning hole 11 is provided at the upper end of the water meter support frame 2, and a side push cylinder 12 is provided at the outer end of the meter clamp joint 5.

[0046] The straightening clamp plate 7 is located at the upper end of the water meter mounting frame 6, and the straightening clamp plate 7 moves laterally at the upper end of the water meter mounting frame 6. The straightening cylinder 8 is located at the lower end of the water meter mounting frame 6. The movable end of the straightening cylinder 8 is fixedly connected to the lower end of the straightening clamp plate 7. A sealing ring is provided at the inner end of the meter clamping joint 5, and the two ends of the water meter to be filled are sealed and connected to the meter clamping joint 5 through the sealing ring.

[0047] The device can be compatible with the support, fixation and clamping limit of water meters of different calibers (size range: DN15-DN32);

[0048] Advantage 1: The device has a wide range of applicability and can complete support, fixation and clamping and limiting for movements of different sizes, types and functions;

[0049] Advantage 2: It replaces the process of manually identifying the water meter with the naked eye and adjusting it by hand, and enables the water meter to be fixed in the required direction with limit support).

[0050] (2) The device is compatible with both manual placement of water meters and mechanical clamp placement of water meters; Advantages: This device can form a complete automatic production assembly line with the previous and next process equipment, or it can work independently, which improves the compatibility of the equipment itself.

[0051] The outer end of the meter clamping joint 5 is fixedly connected to the water filling rack 4. The water filling rack 4 is divided into two groups, inner and outer. A sealing ring is provided at the connection between the inner and outer groups of water filling racks 4, and the inner and outer groups of water filling racks 4 can move laterally relative to each other. The water meter rotation servo motor 9 is connected to the outer side of the water filling rack 4 on the left side.

[0052] The outer end of the meter clamping joint 5 is movably connected to the side push cylinder 12 , and the two ends of the water meter to be filled are respectively clamped on the positioning frame 10 by the positioning holes 11 , and the positioning frame 10 is fixed to the upper end of the water meter mounting frame 6 .

[0053] The device can rotate the water meter at any set angle according to different meter types by rotating the servo motor 9;

[0054] Advantage 1: The rotation angle of the water meter rotation servo motor 9 is set by the program, so that the water flow can overflow along the inclined surface of the glass with a larger angle formed by the rotation of the water meter. The water flow discharges the gas from the cavity between the glass and the movement dial by taking advantage of the fact that the density of water is heavier than that of air. This is one of the key points of this process. If the glass cannot produce an upward inclined surface after the water meter rotates, the water flow will not be easily discharged from the cavity formed by the sealing ring, glass, and movement dial. The sealing ring and the glass are easy to fit together to form a semi-open cavity. A small amount of gas is easy to remain at the joint between the glass and the sealing ring, thereby affecting the exhaust effect.

[0055] Advantage 2: The water meter rotation servo motor 9 can be set to rotate at any angle according to different meter types through the program, ensuring the effectiveness and consistency of water filling and exhaust of different types of wet water meters; Advantage 3: The rotation angle and rotation action are automatically completed by the set program.

[0056] The side thrust cylinder 12 is connected by connecting the inner and outer sets of water injection racks 4 at the outer end of the clamping joint 5;

[0057] Advantage 1: This structure not only meets the requirement that the side push cylinder 12 pushes the meter clamping joint 5 to clamp the meter, but also meets the requirement that the meter clamping joint 5 is connected and rotated with the water meter rotation servo motor 9;

[0058] Advantage 2: Using the side push cylinder 12 to push the meter clamping joint 5 of the water meter on both sides can generate a stable clamping force to meet the requirements of weight differences of different types of water meters.

[0059] The glass orienting block 13 is fixedly connected to the orienting block linkage arm 14 , and the lower end of the orienting block linkage arm 14 is movably connected to the orienting block rotating cylinder 15 . A support frame is provided at the lower end of the orienting block rotating cylinder 15 , and the support frame is used to support the movable end of the orienting block linkage arm 14 .

[0060] The orienting block rotates the cylinder 15 to drive the glass orienter of the water meter to press the lower part of the water meter glass to the set position (usually the lower part of the glass is set close to the edge of the fastening ring);

[0061] Advantage 1: By rotating the cylinder 15 (with adjustable rotation range) through the directional block, it can be adjusted according to different types of wet water meters, thereby improving the adaptability of the mechanism to the types of water meters;

[0062] Advantage 2: The glass orienter of the water meter is pressed on the lower part of the water meter glass to set the position, replacing the process of manually controlling the glass by naked eyes and hands, and the pressing accuracy and consistency are good, ensuring the consistency of water injection and exhaust effect;

[0063] This is one of the key points of this process, because the movement is installed in the limiting guide groove of the water meter housing. If there is no glass orienter of the water meter to press the glass, the movement will be washed out of the limiting guide groove of the water meter housing by the water flow from the inside of the water meter housing, resulting in failure of the installation of the water meter movement (the length of the limiting guide groove of the water meter housing is generally less than 4mm). To this end, the upper part of the glass must be able to be separated from the movement dial and the sealing ring by the impact of the water flow to destroy the closed cavity formed by the three, and the movement must be prevented from being simultaneously washed out of the limiting guide groove of the water meter housing, so this mechanism is needed to ensure this.

[0064] A moving cylinder 19 is provided at the outer end of the fastening ring tightening assembly.

[0065] The fastening ring and tightening plate 16 are linked through the annular groove 17 and the linkage spring 18. The linkage spring 18 is annularly sleeved in the annular groove 17. A rotating cylinder is provided at the upper end of the fastening ring and tightening plate 16. A gear ring is fixed to the outer end of the rotating cylinder. A linkage gear is meshed at the outer end of the gear ring. The center of the linkage gear is movably connected to the tightening rotating cylinder 20.

[0066] The outer ends of the rotating cylinder, the gear ring and the linkage gear are wrapped with an integrated block, and the integrated block moves up and down along the water injection machine 1 through the moving cylinder 19.

[0067] (6) The wet water meter is tightened by tightening the rotating cylinder 20. Different water meter types can be adapted by replacing the tightening ring and tightening plate 16.

[0068] Advantages: This structure meets the tightening requirements of different types of wet water meters with different meter head types and different set torques (the tightening torque can be set at 1-200N / m). A residual water through hole 22 is provided in the center of the water meter mounting frame 6, and a residual water discharge trough 21 is provided at the lower end of the residual water through hole 22, and a residual water pipe 23 is provided at the lower end of the residual water discharge trough 21.

[0069] The automatic water filling switch is automatically controlled by the program to adjust the switch and flow rate;

[0070] Advantage 1: The water filling time can be set and automatically adjusted according to different types of water meters to meet the water filling and exhaust requirements of different types and sizes of wet water meters;

[0071] Advantage 2: The water injection flow rate can be automatically adjusted according to different stages. This is one of the key points of this process. After the water meter glass orienter returns to the safe waiting position, if the water injection flow rate is not reduced, the movement lacks the pressure of the orienter and may be flushed out of the limit groove of the water meter case by the water flow, resulting in the failure of the movement installation. Therefore, before the water meter glass orienter returns to the safe waiting position, the water flow is adjusted to the set small flow rate to ensure that the existing water flow continues to flow out of the case without flushing out of the movement, and then the water meter is rotated.

[0072] When using this application:

[0073] In the first step, the wet water meter with the pre-tightened fastening ring in the previous process is installed on the water meter installation plate in the water injection machine 1 through the mechanical clamping claw, and the meter clamping joint 5 clamps the water inlet and outlet of the water meter respectively through the corresponding water injection frame 4 under the push of the side push cylinder 12;

[0074] In the second step, the clamped water meter is driven by the water meter rotation servo motor 9 to rotate clockwise by a set angle (the flip angle is set between 5° and 85°);

[0075] In the third step, the directional block rotating cylinder 15 on the side presses the glass directional block 13 to the set position below the water meter glass (usually the glass is set close to the edge of the fastening ring) to prevent the water flow from pushing the movement inside the case out of the case opening beyond a certain range (the length of the movement beyond the case opening is less than or equal to 3mm). At the same time, water is injected into the water meter through the water injection pipe 3. Under the impact of the water flow, an angle (between 0-15°) is generated between the upper part of the glass and the movement dial, which is used to destroy the closed cavity formed by the movement dial, sealing ring and glass inside the case, which is conducive to the process of water flow overflowing from the bottom along the glass to discharge the gas;

[0076] Step 4: Turn on the automatic water filling switch (through the electric on-off valve) to fill water into the water meter. The filling time is set at 4S-12S (the specific filling time varies depending on the type of meter, and the general filling time is completed within 4-12 seconds);

[0077] Step 5: Reduce the water injection flow rate and turn the rotary cylinder to rotate the glass orienter of the water meter back to the safe waiting position;

[0078] Step 6: Start the water meter rotation servo motor 9 to drive the water meter after water filling to rotate counterclockwise around the water inlet and outlet axis by a set angle (the same as the previous clockwise flip angle) to realize the return of the water meter. The front and rear ends of the straightening clamp 7 and the straightening cylinder 8 limit the clamping of both sides of the water meter to ensure that the water meter is stable in the vertical position, which is convenient for the upper moving cylinder 19 to drive the fastening ring tightening plate 16 to descend and align;

[0079] Step 7: While maintaining the low flow water injection state, the fastening ring tightening plate 16 on the upper part of the wet water meter is lowered under the drive of the moving cylinder 19, and the fastening ring of the water meter is covered by the fastening ring tightening plate 16, and tightened according to the set torque (the tightening torque can be automatically set in the range of 1-200N / m);

[0080] Step 8: The mobile cylinder 19 drives the tightening plate 16 of the fastening ring to lift, the automatic water filling switch is turned off, the limit block of the side pneumatic limit assembly is released, and the water meter inlet and outlet clamp joint 5 is released. The excess water on the lower side of the water meter is discharged from the residual water through hole 22 and the residual water discharge trough 21 through the residual water pipe 23, and can also be collected and recycled with the filter. The water meter that has completed water filling, exhaust and tightening is taken away by mechanical claws or manually.
