Description

Technical Field

[0001] The present invention relates to the technical field of smart water meter assembly, and in particular to an assembly device for a smart water meter. Background Art

[0002] Smart water meters are a type of flow meter that is currently widely used. They are called smart because they are different from ordinary mechanical water meters. Figure 1-4 It has an intelligent meter head 2, which has an input gear 202 and a corresponding code disk and a magnetic sensor inside. The magnetic sensor detects the number of magnets on the code disk and determines the rotation speed of the code disk. The code disk is connected to the input gear 202, so the rotor speed inside the water meter can be converted into an electrical signal to obtain specific parameter values ​​such as flow rate and flow velocity.

[0003] When installing this type of smart water meter, on the one hand, the smart meter head 2 needs to be fixed to the upper end of the metering chamber component 1, and on the other hand, when the two are docked and assembled, it is also necessary to ensure that the output gear 103 in the metering chamber is meshed with the input gear 202 on the smart meter head 2, otherwise the flow information cannot be transmitted. At present, the biggest difficulty in assembly is that the smart meter head 2 and the metering chamber component 1 are not transparent, and it is impossible to see whether the input gear 202 and the output gear 103 are correctly aligned during assembly, which often leads to the smart meter head 2 being unable to be buckled on the upper end of the metering chamber component 1 due to the interference of the two gears. Therefore, during assembly, the assembler needs to control the relative position between the smart meter head 2 and the metering chamber component 1 at the beginning, otherwise it will be impossible to assemble. For assembly, the workers need to have extremely rich assembly experience to estimate whether the gears will be aligned, or during processing, the matching size between the smart meter head 2 and the upper end of the metering chamber component 1 is increased, that is, the radial gap between the two is slightly increased, so that the gap between the meter head and the metering chamber can be increased by slightly pitching and deflecting the smart meter head 2, and the gap between the meter head and the metering chamber can be increased by observing and adjusting this gap from multiple angles to ensure that the above two gears are aligned and then can be smoothly meshed. However, these are very difficult and time-consuming. Therefore, the final assembly is often required to be carried out by extremely skilled workers. Summary of the invention

[0004] In view of the introduction to the above technical status quo, the purpose of the present invention is to provide an assembly device for a smart water meter, so as to better solve the technical problem that when assembling the smart meter head and the metering chamber components, it is difficult to adjust the relative position relationship between the input gear and the output gear, which makes it difficult for the two gears to align and mesh, thereby causing difficulty in the overall assembly of the smart water meter.

[0005] To achieve the above-mentioned purpose, an assembly device for a smart water meter of the present invention includes a clamping component for clamping a smart meter head. After the clamping component clamps the smart meter head, it can be coaxially installed on the upper end of the metering chamber component, and the input gear of the smart meter head is meshed with the output gear at the upper end of the metering chamber component; the present invention also includes an adjusting component that can be inserted into the threading hole on the top side of the metering chamber component. After the adjusting component is inserted into the threading hole, it can clamp the gear shaft of the output gear and drive it to rotate an angle, and when the clamping component temporarily places the smart meter head above the metering chamber component in advance, the adjusting component that has clamped the gear shaft is swung, and the smart meter head can smoothly fall to the docking position and the output gear and input gear are meshed.

[0006] Furthermore, the adjusting component includes a screw rod, one end of which is hinged with a clamping part, and a pressure-bearing spring is connected between two clamping plates of the clamping part on one side close to the hinged end, and the pressure-bearing spring enables the two clamping plates to maintain an angle value relative to each other under normal conditions;

[0007] A threaded tube is threadedly sleeved on the screw rod, and one end of the threaded tube has a pressure cylinder. When the threaded tube rotates on the screw rod, the pressure cylinder can move toward the clamp plate and sleeve on the two clamp plates, so that the pressure spring is squeezed and the angle value becomes smaller, until the two clamp plates clamp the gear shaft, and the threaded tube cannot move forward any further.

[0008] Furthermore, both ends of the clamp plate are inclined in the same direction to form a turning structure between the two ends, and an arc-shaped rubber pressure plate is provided at the turning structure, and the rubber pressure plate can be tightly attached to the cylindrical surface of the gear shaft, and under normal conditions, the spacing between the free ends of the two clamp plates is large enough to enable the free end of the clamp part to be inserted into the threading hole, and in the process of further inserting into the interior of the metering chamber component, the two clamp plates gradually move closer due to the extrusion contact with the hole wall of the threading hole.

[0009] Furthermore, each of the two clamp plates has a sink at its free end, and the two sinks are oriented in opposite directions to each other, so that when the two clamp plates are brought close to each other, the surface of one sink can be in sliding contact with the surface of the other sink.

[0010] Furthermore, the pressure-bearing spring sheet is a V-shaped sheet structure, and two sides of the opening are respectively connected to the two clamp plates.

[0011] Furthermore, a transmission wheel is fixed to one end of the threaded tube away from the clamping part, so that the threaded tube is driven on the screw rod in the form of a thread pair through the transmission wheel.

[0012] Furthermore, the clamping component includes an upper ring plate and a lower ring plate, and a plurality of claws are slidably installed radially on the lower ring plate. A driving column is fixed perpendicularly to the surface of each claw, and the driving column passes through the guide bar hole set in the upper ring plate and slidably cooperates with the guide bar hole.

[0013] Furthermore, the claws correspond one-to-one to the slots on the outside of the smart meter head, and the upper ring plate rotates through the rotation of the driving shaft coaxially fixed thereto, so that all the claws move synchronously and are inserted into their respective corresponding slots to clamp the smart meter head.

[0014] Furthermore, the driving shaft is fixedly connected to the end face of the upper ring plate through a plurality of connecting rods, a driving gear is fixed to the top end of the driving shaft, the driving gear is meshed with the first rack, the first rack is meshed with the second rack through a plurality of speed gears, one end of the second rack has a rectangular groove, the rectangular groove is provided for magnetically fixing one end of a rectangular tube, the other end of the rectangular tube is fixedly connected with the adjusting component, so that when the driving shaft rotates to clamp the smart meter head, the adjusting component enters the metering chamber component through the threading hole.

[0015] Furthermore, a blind hole is provided on the inner wall of the rectangular groove, a first magnet is fixed at the bottom of the blind hole, and a protruding second magnet is fixed on the side wall at one end of the rectangular tube. When the second magnet is inserted into the blind hole and fixed by magnetic attraction with the first magnet, the adjusting component can move along the axial direction of the threading hole.

[0016] Beneficial effect: The present invention utilizes a variable-size adjustment component to enter the metering chamber component through the threading hole, and then rotates the gear shaft so that the two gears, one up and one down, one left and one right, can be adjusted to a state of direct meshing, so as to facilitate the assembly of the smart meter head and the metering chamber component. The structure is simple and practical, and easy to manufacture. It completely solves the problem that it is impossible to observe whether the output gear and the input gear are meshed and aligned because they are in the meter head and the metering chamber. It greatly reduces the tediousness of trying to mesh the smart meter head and the metering chamber through misalignment during installation, and the assembly is faster.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention will be fully described below, and some core features of the embodiments will be specifically shown in the accompanying drawings, wherein the same or similar reference numerals in the drawings represent the same or similar technical features, or structures or steps or processes with similar functions. Other embodiments replaced by ordinary technicians based on these embodiments without the need for creative work also belong to the protection scope of the present invention.

[0028] See also Figure 5The present embodiment is a specific assembly device for a smart water meter, and its structure mainly includes a clamping component for clamping the smart meter head 2. After the clamping component clamps the smart meter head 2, it can be coaxially installed on the upper end of the metering chamber component 1, and the input gear 202 of the smart meter head 2 is meshed with the output gear 103 at the upper end of the metering chamber component 1, so that the signal in the metering chamber can be transmitted to the smart meter head 2 and directly displayed in the form of electronic data. Specifically, the assembly equipment for the smart water meter is also specially provided with an adjusting component, which can be inserted into the threading hole 102 on the top side of the metering chamber component 1 to operate the corresponding components in the metering chamber, that is, after the adjusting component is inserted into the threading hole 102, it can clamp the gear shaft 104 of the output gear 103, thereby driving the gear shaft 104 to rotate an angle by swinging or rotating the adjusting component. This angle is mainly selected according to the misalignment between the input gear 202 and the output gear 103 during installation. This is because when the input gear 202 moves down with the smart meter head 2, its corresponding gear teeth may not be aligned with the gear tooth gap of the output gear 103 below, resulting in the input gear 202 and the output gear 103 conflicting with each other in the vertical direction, and then the smart meter head 2 cannot move down normally, and cannot reach the set position for assembly with the metering chamber component 1, resulting in obstruction of the assembly of the smart water meter. In addition, in this embodiment, when the clamping component pre-positions the smart meter head 2 on the metering chamber component 1, that is, the smart meter head 2 is first moved to the top of the metering chamber component 1, when the two gears contact each other and the smart meter head 2 cannot be moved down and docked normally, it is necessary to rotate the output gear 103, that is, at this time, swing the adjustment component that has clamped the gear shaft 104. When slowly trying to swing, the smart meter head 2 can fall freely and smoothly at a certain moment or position, so that the output gear 103 and the input gear 202 are engaged, and the smart meter head 2 can also be docked with the metering chamber component 1.

[0029] Specifically, if Figure 5-6As shown, the adjustment component includes a screw rod 6, one end of which is hinged with a clamping part, which clamps the gear shaft 104. The clamping part is specially connected to the side of the hinged end between the two clamping plates 3 of the clamping part. The pressure-bearing spring 9 makes the two clamping plates 3 maintain an angle value relative to each other under normal conditions, that is, the two clamping plates 3 are opened to a certain extent, so that the gear shaft 104 can be quickly included in its angle area for further clamping. At the same time, a threaded tube 5 is threadedly sleeved on the screw rod 6, and one end of the threaded tube 5 has a pressure cylinder 4, which is a section of round tube and is directly larger than the threaded tube 5. When the threaded tube 5 rotates on the screw rod 6, the pressure cylinder 4 can move toward the clamp plate 3 and be sleeved on the two clamp plates 3, so that the pressure-bearing spring sheet 9 is squeezed, and the angle value mentioned above becomes smaller, until the two clamp plates 3 get close to each other and can finally clamp the gear shaft 104, and the threaded tube 5 cannot move forward accordingly. At this time, the gear shaft 104 is clamped, and the output gear 103 can be slightly rotated by an angle by rotating the clamp part, and then the smart meter head 2 falls to the position where the two mesh with each other under the action of its own weight, which can facilitate the subsequent tightening of the smart meter head 2. For example, when the metering chamber part The upper end of the component 1 that is used to be connected with the smart meter head 2 is a section of a smooth cylindrical structure in the upper half and a pipe thread is provided in the lower half. The smart meter head 2 can be dropped to the pipe thread section in the lower half after the relative relationship between the two gears is adjusted into place, and finally the smart meter head 2 is tightened. Alternatively, when the smart meter head 2 and the metering chamber component 1 are connected by bolts, when the output gear 103 and the input gear 202 are meshed into place, the smart meter head 2 automatically drops into place, and a circle of bolts (not shown in the figure) around the smart meter head 2 and the metering chamber component 1 can be directly tightened.

[0030] As one of the implementation structures, such as Figure 5-7 The two ends of each clamp plate 3 are inclined in the same direction, so that a turning structure can be formed between the two ends, and there is an arc-shaped rubber pressure plate 8 at the turning structure, which can be close to the cylindrical surface of the gear shaft 104 and is used to clamp the gear shaft 104. Under normal conditions, the spacing between the free ends of the two clamp plates 3 is large enough to allow the free end of the clamp part to be inserted into the threading hole 102, so that the adjustment component can be inserted into the threading hole 102, and in the process of further inserting into the metering chamber component 1, the two clamp plates 3 gradually move closer due to the squeeze contact with the hole wall of the threading hole 102. When the clamp part completely enters the metering chamber, the clamp part will automatically open and restore to its original state. At this time, through the axial movement of the above-mentioned pressure cylinder 4, the clamp part can firmly clamp the gear shaft 104 in the metering chamber component 1.

[0031] In order to reduce the structural size of the clamp part, such as Figure 7In this embodiment, each of the two clamp plates 3 has a sink 301 at its free end, and the two sinks 301 are oriented in opposite directions. In this way, when the two clamp plates 3 are brought close to each other, the surface of one sink 301 can slide in contact with the surface of the other sink 301, thereby preventing the two rubber pressure plates 8 from being fully squeezed and contacted with the gear shaft 104 after the free ends come into contact with each other. This design detail is particularly noteworthy.

[0032] The pressure spring sheet 9 in the above embodiment can be a V-shaped sheet structure, and the two sides of the opening are respectively connected to the two clamp plates 3, so that the original state of the clamp part can be well maintained under normal conditions. For the driving of the pressure cylinder 4, a transmission wheel 7 can be fixed to the end of the threaded tube 5 away from the clamp part, so that the transmission wheel 7 drives the threaded tube 5 on the screw rod 6 in the form of a thread pair, so that the pressure cylinder 4 is sleeved on the hinged end of the clamp part, and the above-mentioned transmission wheel 7 can be connected to a transmission element such as a motor, of course, it can also be manually rotated.

[0033] As another implementation structure, the clamping member is as follows Figure 8 As shown, it mainly includes an upper ring plate 10 and a lower ring plate. The upper ring plate 10 can be coaxially rotatably mounted on the lower ring plate, and the lower ring plate is fixedly arranged on the corresponding auxiliary structure. A plurality of claws 11 are slidably mounted on the radial direction of the lower ring plate. A driving column 13 is fixed perpendicularly to the surface of each claw 11. The driving column 13 can be a cylinder. The driving column 13 passes through the guide bar hole 12 set on the upper ring plate 10 and slides with the guide bar hole 12, so as to guide all the driving columns 13 to move synchronously and clamp or release the smart meter head 2 by utilizing the shape of the guide bar hole 12. During manufacturing, the claw 11 corresponds to the slot 201 on the outside of the smart meter head 2 one by one. When the claw 11 is inserted into the slot 201 and is in place, the smart meter head 2 can be firmly clamped. As for the rotation of the upper ring plate 10, it can be rotated by the rotation of the drive shaft 15 coaxially fixed thereto, so that all the claws 11 are synchronously moved and inserted into their respective corresponding slots 201 to clamp the smart meter head 2 so as to move the smart meter head 2 later.

[0034] In the above implementation structure, the smart meter head 2 can be clamped first and moved vertically downward to the predetermined initial position at the upper end of the metering chamber component 1. For example, the axial fitting length of the connecting end corresponding to the metering chamber component 1 is 4 cm. At this time, the axial length of the smart meter head 2 coaxially connected with it is only 2.5 cm. Then, at this initial position, the input gear 202 is just located on the upper surface of the output gear 103 and contacts it. If the two gears are not accurately aligned at this time, even if the smart meter head 2 is released, the smart meter head 2 will not automatically fall into place, but will stay at the initial position. At this time, it is necessary to adjust the component axially inserted into the threading hole 102, and the clamping part completely enters the metering chamber component 1, so that the gear shaft 104 can be clamped by just closing the two clamp plates 3. Slightly turn the gear shaft 104. Once the two gears are correctly aligned, the smart meter head 2 will fall down by itself and the entire 4 cm long fitting length of the connecting end will be caught. It should be specially noted here that, in all embodiments, the design is based on the principle that the adjusting component clamps the gear shaft 104 for rotation. However, how to install the specific smart meter head 2, how to drive it to a certain middle of the installation, and when and how the adjusting component moves as a whole into the threading hole 102, etc., all require adaptive design and selection by technical personnel in this field. For example, it needs to be determined according to the specific connection relationship between the smart meter head 2 and the metering chamber component 1 mentioned above. This embodiment does not and cannot impose specific related restrictive structures, and it is not limited to the aforementioned method.

[0035] For example, the specific motion execution can also be as follows Figure 8 In the structure shown, the driving shaft 15 is fixedly connected to the end face of the upper ring plate 10 through a plurality of connecting rods 16, and a driving gear 14 is fixed to the top of the driving shaft 15, and the driving gear 14 is meshed with the first rack 17, and the first rack 17 can be arranged on the upper side of the driving gear 14, and the first rack 17 is meshed with the second rack 19 through a plurality of speed change gears 18, and the second rack 19 is located on the lower side of the first rack 17, and one end of the second rack 19 has a rectangular groove, and the rectangular groove is located on one side of the second rack 19. The rectangular groove is magnetically fixed to one end of a rectangular tube 20, and after the two are magnetically fixed, the movement of the second rack 19 directly moves the adjusting component linearly. For example, an adjusting component is fixedly connected to the other end of the matrix tube 20. One of the processes of rotating the driving shaft 15 is the process of clamping the smart meter head 2. During this period, the adjusting component enters the metering chamber component 1 through the threading hole 102 to clamp the gear shaft 104 and rotate, thereby adjusting the alignment relationship between the output gear 103 and the input gear 202 so that the two gears are just meshed. At the same time, after releasing the smart meter head 2, the smart meter head 2 can naturally fall into place.

[0036] When the smart meter head 2 finally moves down to the installation position, the smart meter head 2 can be released by the direct clamping component, that is, the driving shaft 15 can be reversed, and the above-mentioned adjusting component is locked to the clamping part by the pressure cylinder 4 on the threaded tube 5, so that the adjusting component and the gear shaft 104 are firmly connected together, and the pulling force when the second rack 19 moves in the opposite direction overcomes the magnetic attraction between the torque tube 20 and the second rack 19, so that the adjusting component remains in the metering chamber component 1, so that the rotation of the gear shaft 104 can be adjusted at any time; or after the two gears are adjusted into place, the first rack 17 moves down together with the clamping component, and at this time the speed gear 18 should be designed as a cylindrical gear, so that when the first rack 17 moves down along the axial direction of the metering chamber component 1, it is always not separated from the speed gear 18.

[0037] In addition, if Figure 8 As shown, the present embodiment has a blind hole on the inner wall of the rectangular groove, a first magnet 22 is fixed at the bottom of the blind hole, and a protruding second magnet 21 is fixed on the side wall at one end of the rectangular tube 20. When the second magnet 21 is inserted into the blind hole and fixed to the first magnet 22 by magnetic attraction, the rectangular tube 20 moves linearly with the second rack 19, that is, the adjusting component can move along the axial direction of the threading hole 102, stop moving after moving to a set depth, and then rotate the rectangular tube 20 at this time, so that the second magnet 21 of the rectangular tube 20 is disengaged from the above-mentioned blind hole, so as to rotate the adjusting component connected thereto, and by rotating the output gear 103, the alignment relationship between the corresponding gear teeth and the tooth gaps when the input gear 202 and the output gear 103 are assembled in an up-down, left-right position is adjusted.

[0038] The above series of specific implementation details are merely some preferred embodiments of the present invention and cannot be used to limit the protection scope of the claims of the present invention. A person skilled in the art can simply change the design ideas based on the understanding of the above embodiments and the reference to the basic principles recorded in the claims of the present invention. However, these design changes still fall within the protection scope of the invention.
