Description

Technical Field

[0001] The invention relates to the technical field of water meter cap screwing, and in particular to an automatic cap screwing device for water meter production. Background Art

[0002] In the field of water meter production, the installation of water meter covers and observation glasses is a key link. Traditional water meter cover installation methods mostly rely on manual operation or basic mechanical devices, which are extremely inefficient and difficult to guarantee installation accuracy and stability. Especially in the torque control link, there is a lack of precise adjustment mechanism. Either the torque is too large, which is very easy to damage the water meter cover; or the torque is too small, which cannot ensure a firm installation. This makes the installation quality of the water meter cover uneven, seriously affecting the reliability of the product.

[0003] When it comes to installing water meters of different types and specifications, the traditional method is seriously inadequate in adaptability. Due to the lack of a flexible adjustment structure, it is impossible to effectively match the specific size and shape of the water meter, resulting in frequent position deviations, unstable clamping and other problems during the installation process, greatly reducing the success rate and efficiency of the installation.

[0004] For the installation of observation glass, the degree of automation is low, and the buffering and positioning measures are insufficient during the adsorption and installation process, which makes the observation glass easy to be damaged, increasing the production cost and the defective rate.

[0005] In addition, the traditional installation device lacks flexibility and adaptability in the design of the clamping parts and cannot meet the needs of various sizes and shapes. At the same time, the maintenance and adjustment of the equipment are complicated and cumbersome, further increasing the cost and time investment of production. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1-14The water meter production automatic capping device shown in the figure comprises a meter case 1, an observation glass 2 and a water meter cover 3, a frame 4 and a meter cover mounting mechanism 5, a bearing seat 6 and a glass mounting mechanism 7 all mounted on the frame 4, a meter cover mounting manipulator is provided on the frame 4, the meter cover comprises a first mounting frame 8 mounted on the meter cover mounting manipulator and a capping drive assembly 9, a torque adjustment assembly 10 and a meter cover clamping assembly 11 arranged from top to bottom, the meter cover clamping assembly 11, the capping drive assembly 9 and the torque adjustment assembly 10 are all coaxially arranged, the capping clamping assembly comprises a multi-claw chuck 12 for clamping the water meter cover 3, and the capping The driving component 9 is arranged on the first mounting frame 8, and the watch cover clamping component 11 is connected to the output end of the screw cover driving component 9 through the torque adjustment component 10. The bearing seat 6 for supporting the watch case 1 is installed on the working platform of the frame 4. The bearing seat 6 is provided with a limit clamping component 13 for clamping both sides of the watch case 1. The glass mounting mechanism 7 is arranged above the working platform. The glass mounting mechanism 7 includes a replaceable first bearing plate 14 and an adsorption clamping device for clamping the observation glass 2 and the sealing gasket. The first bearing plate 14 is provided with a glass mounting groove 15 and a gasket mounting groove 16. The first bearing plate 14 is located next to the bearing seat 6.

[0040] The present invention adopts an integrated meter cover installation mechanism 5, which integrates the functions of rotating cover drive, torque adjustment and meter cover clamping in one device, thereby improving installation efficiency and accuracy. The torque adjustment component 10 is used to transmit the rotation drive function of the multi-claw chuck 12, thereby reducing the deviation during the installation process, ensuring the installation quality, and preventing the water meter from being damaged due to too many twisting turns or the water meter cover 3 from being improperly installed due to insufficient twisting turns. The torque adjustment component 10 has two adjustment modes, manual and automatic, and can flexibly adjust the transmitted torque according to water meters of different specifications, thereby improving the application range of the equipment.

[0041] During the production of the water meter, the water meter case 1 to be installed with the meter cover is first fixed by the limit clamping assembly 13 on the bearing seat 6. The limit clamping assembly 13 can stably clamp the case 1 from both sides to ensure that it will not move during subsequent installation operations.

[0042] The first mounting frame 8 on the meter cover installation manipulator carries the capping drive assembly 9, the torque adjustment assembly 10 and the meter cover clamping assembly 11. The multi-claw chuck 12 can accurately clamp the water meter cover 3. The capping drive assembly 9 provides power for the rotational installation of the meter cover. The torque adjustment assembly 10 has two adjustment modes, manual and automatic, and can flexibly adjust the torque according to the installation requirements of different models of water meters. When the torque reaches the set value, after exceeding the set torque, the rotational driving force of the capping drive assembly 9 will no longer continue to transmit downward, that is, it cannot drive the multi-claw chuck 12 to rotate, and thus it cannot continue to drive the water meter cover 3 to rotate, thereby effectively protecting the water meter and the installation components, and avoiding damage caused by excessive torque. After the meter cover clamping assembly 11 clamps the water meter cover 3, the capping drive assembly 9 starts to work. At this time, according to the specific water meter model, the torque value of the torque adjustment assembly 10 is set manually or automatically. During the process of screwing the cover, once the torque reaches the set value, the torque adjustment component 10 will function to prevent the rotational driving force from continuing to be transmitted downward, and then the meter cover clamping component 11 will stop rotating, completing the precise tightening and installation of the water meter cover 3.

[0043] When installing the observation glass 2, the adsorption and clamping device will clamp the observation glass 2 and the sealing gasket. Since the first supporting plate 14 is provided with a glass mounting groove 15 and a gasket mounting groove 16, the observation glass 2 and the sealing gasket can be accurately positioned. The adsorption and clamping device moves the observation glass 2 and the sealing gasket to the correct position above the watch case 1 for installation.

[0044] The meter cover installation robot moves the meter cover clamping assembly 11 to the position of the water meter cover 3, the multi-claw chuck 12 clamps the water meter cover 3, and the cover screwing drive assembly 9 generates rotational power. Then, according to the requirements of different types of water meters, the torque adjustment assembly 10 is adjusted manually or automatically to reach an appropriate torque value. Finally, the power adjusted by the torque adjustment assembly 10 is transmitted to the meter cover clamping assembly 11 to achieve precise tightening and installation of the water meter cover 3. At the same time, the adsorption and clamping device of the glass installation mechanism 7 accurately installs the observation glass 2 and the sealing gasket on the meter case 1.

[0045] The capping drive assembly 9 includes a first rotary driver 17, a first rotating shaft 18, a rotary transmission disk 19 and a telescopic connecting rod 20. The torque adjustment assembly 10 includes an adjusting mounting cylinder 21. The first rotary driver 17 is vertically fixedly mounted on the first mounting frame 8. The first rotating shaft 18 is vertically axially connected to the first mounting frame 8. The output end of the first rotary driver 17 is fixedly connected to the top of the first rotating shaft 18. The middle part of the first rotating shaft 18 is fixedly connected with a coaxially arranged connecting disk 22. The adjusting mounting cylinder 21 is rotatably arranged below the connecting disk 22. The bottom end of the first rotating shaft 18 is transmission-connected to the torque adjustment assembly 10. The rotary transmission disk 19 is coaxially arranged with the adjusting mounting cylinder 21. The rotary transmission disk 19 is vertically slidably arranged on the outer side wall of the adjusting mounting cylinder 21. The rotary transmission disk 19 is transmission-connected to the torque adjustment assembly 10. One end of the telescopic connecting rod 20 is fixedly connected to the first mounting frame 8, and the other end of the telescopic connecting rod 20 is slidably matched with the rotary transmission disk 19 through an annular connecting groove.

[0046] During the cover installation operation, the first rotary driver 17 of the cover screw drive assembly 9 is started, driving the first rotating shaft 18 to rotate. The first rotating shaft 18 obtains power by being fixedly connected to the output end of the first rotary driver 17 through the top. When the connecting disk 22 in the middle of the first rotating shaft 18 rotates, it drives the adjustment installation cylinder 21 below to rotate. At the same time, the rotating transmission disk 19 is coaxially arranged with the adjustment installation cylinder 21, and it slides vertically on the outer side wall of the adjustment installation cylinder 21, so as to effectively cooperate with the torque adjustment assembly 10 in transmission. One end of the telescopic connecting rod 20 is fixedly connected to the first mounting frame 8, and the other end is slidably matched with the rotating transmission disk 19 through the annular connecting groove, which not only ensures the smooth and stable sliding of the rotating transmission disk 19, but also can accurately control the position and movement of the rotating transmission disk 19 during the transmission process. The sliding design of the rotating transmission disk 19 increases the flexibility and adjustability of the transmission, and can achieve precise transmission control according to different work requirements and torque adjustment requirements.

[0047] The torque adjustment assembly 10 also includes an adjustment disk 23, a torque adjustment spring 24, a mounting disk 25, a first ratchet disk 26, a second ratchet disk 27 and a pushing device 28 coaxially arranged in the adjustment mounting cylinder 21 from top to bottom. A plurality of vertical slide grooves 29 are annularly opened on the side wall of the upper half of the adjustment mounting cylinder 21. The adjustment disk 23 is fixedly connected to the rotating transmission disk 19 located on the outer side wall of the adjustment mounting cylinder 21 through a plurality of connecting blocks 30 slidably arranged in the vertical slide grooves 29. The pushing device 28 is installed on the first mounting frame 8. The pushing device 28 is transmission-connected to the rotating transmission disk 19. The torque adjustment spring 24 is installed on the first mounting frame 8. The two ends of the spring 24 are fixedly connected to the adjusting disk 23 and the mounting disk 25 respectively, the first ratchet disk 26 is fixedly connected to the mounting disk 25 and both are provided with a center hole for the first rotating shaft 18 to pass through, the first ratchet disk 26 is meshed with the second ratchet disk 27, the first rotating shaft 18 passes through the first ratchet disk 26 and the mounting disk 25 and is fixedly connected to the second ratchet disk 27, a plurality of vertical limit strips 31 are annularly provided on the inner side wall of the lower half of the adjusting mounting cylinder 21, a limit groove 32 is provided on the outer side wall of the mounting disk 25, and the mounting disk 25 is limitedly slidably connected to the adjusting mounting cylinder 21 through the vertical limit strips 31 and the limit grooves 32.

[0048] In the torque adjustment assembly 10, when the rotating transmission disk 19 moves, the connecting block 30 slides in the vertical slide groove 29, thereby driving the adjustment disk 23 to move up and down along the inner wall of the adjustment mounting cylinder 21. The pushing device 28 is installed on the first mounting frame 8, and it can be connected to the rotating transmission disk 19 in a transmission manner. The components in the pushing device 28 will produce corresponding actions, thereby applying a driving force to the rotating transmission disk 19, so that the rotating transmission disk 19 can move according to the design requirements. The torque adjustment spring 24 can buffer and adjust the size of the force through its own expansion and contraction to achieve the torque adjustment function. The pushing device 28 is used to control the compression amount of the torsion adjustment spring 24.

[0049] The first ratchet plate 26 and the second ratchet plate 27 are meshed with each other. When the first rotating shaft 18 rotates, the second ratchet plate 27 fixedly connected thereto is driven to rotate. Through the meshing action of the first ratchet plate 26 and the second ratchet plate 27, the transmission and adjustment of torque are realized. When the water meter cover 3 is not installed in place, the second ratchet plate 27 can drive the adjusting and installing cylinder 21 to rotate through the first ratchet plate 26 and the installing plate 25. Since the adjusting and installing cylinder 21 is connected to the meter cover clamping assembly 11 by transmission, the rotation of the adjusting and installing cylinder 21 will further drive the meter cover clamping assembly 11 to rotate synchronously, and finally realize the function of driving the water meter cover 3 to rotate synchronously. The installing plate 25 is connected to the adjusting and installing cylinder 21 by a vertical limiting strip 31 and a limiting groove 32. This structural design ensures that the installing plate 25 can only slide stably along the vertical direction in the adjusting and installing cylinder 21 without deviation or shaking in other directions, thereby ensuring the accuracy and stability of the torque adjustment process. When the water meter cover 3 is installed in place, the adjusting and installing cylinder 21 remains stationary. At this time, if the capping drive assembly 9 continues to apply torque, the second ratchet disc 27 will push up the upper first ratchet disc 26 when it rotates. Since the mounting disc 25 is fixedly connected to the first ratchet disc 26, the mounting disc 25 will overcome the elastic force of the torsion adjustment spring 24 and move upward, thereby compressing the torsion adjustment spring 24. In this process, the first ratchet disc 26 is separated from the second ratchet disc 27, realizing the transmission separation function between the capping drive assembly 9 and the water meter cover 3, and avoiding damage to the water meter cover 3 or other components due to excessive force.

[0050] The present invention can automatically adjust the torque and separate the transmission according to the installation state of the water meter cover 3, accurately control the torque during the installation process, improve the accuracy and reliability of the installation, and protect the components from damage.

[0051] The pushing device 28 includes a first pusher 33 and a first push rod 34. The first pusher 33 is vertically fixedly mounted on the first mounting frame 8. The first push rod 34 is vertically arranged beside the first rotating shaft 18. The output end of the first pusher 33 is fixedly connected to the top end of the first push rod 34. The bottom end of the first push rod 34 is transmission-connected to the rotating transmission disk 19.

[0052] During operation, when the rotating transmission disk 19 needs to be pushed automatically, the first pusher 33 is started, so that the first push rod 34 can effectively transmit the thrust to the rotating transmission disk 19, thereby accurately controlling the lifting and lowering of the rotating transmission disk 19, and realizing the automatic operation of torque adjustment during the installation of the water meter cover 3. The movement of the rotating transmission disk 19 can be automatically, stably and accurately controlled, effectively improving the work efficiency and consistency of operation.

[0053] The pushing device 28 also includes a scale 35, a pointer 36, a limit frame 37, a limit connecting column 38 and a manual adjustment device installed at the bottom of the first push rod 34, the manual adjustment device includes a threaded column 39, a threaded sleeve 40 and a locking nut 41, the threaded column 39 is vertically and coaxially arranged directly below the first push rod 34, an outer thread is provided on the outer wall of the upper half of the threaded column 39, the threaded sleeve 40 is rotatably installed at the bottom of the first push rod 34, the interior of the threaded sleeve 40 is provided with an internal thread matching the external thread of the threaded column 39, the locking nut 41 is installed on the first push rod 34, the top of the threaded sleeve 40 is provided with an external thread matching the locking nut 41, one end of the limit connecting column 38 is fixedly connected to the threaded column 39, the other end of the limit connecting column 38 is slidably connected to the limit frame 37, the limit frame 37 is fixedly connected to the first mounting frame 8, the pointer 36 is fixedly installed at the end of the limit connecting column 38 away from the threaded column 39, and the scale 35 is vertically fixedly installed on the first mounting frame 8.

[0054] On the basis of not affecting the normal use of the automatic push function, the function of manual fine adjustment has been added, which greatly improves the flexibility and accuracy of the operation. It can meet the working scenarios with higher requirements for adjustment accuracy under special working conditions, and can adapt to the screw-on assembly needs of more types of water meter covers, thereby improving the practicality of the equipment.

[0055] When manual fine adjustment is required, the operator rotates the threaded sleeve 40, and the threaded column 39 moves up and down in the vertical direction through the interaction of the threads. The locking nut 41 is installed on the first push rod 34, and the top of the threaded sleeve 40 is provided with an external thread matching the locking nut 41. After the adjustment is completed, the threaded sleeve 40 can be fixed by tightening the locking nut 41 to prevent it from rotating accidentally. One end of the limit connecting column 38 is fixedly connected to the threaded column 39, and the other end is slidably connected to the limit frame 37. The limit frame 37 is fixedly connected to the first mounting frame 8, ensuring that the threaded column 39 can only move in the vertical direction. The pointer 36 is fixedly installed at the end of the limit connecting column 38 away from the threaded column 39, and the scale 35 is vertically fixedly installed on the first mounting frame 8. When the threaded sleeve 40 is manually adjusted, the up and down movement of the threaded column 39 will drive the pointer 36 to move on the scale 35. The operator can clearly and intuitively understand the degree and amount of adjustment through the indication of the pointer 36 on the scale 35, thereby achieving precise manual adjustment.

[0056] The screw cap clamping assembly also includes a mounting ring 42, a connecting support plate 43, a clamping plate 44, a rubber resistance block 45 and a first spring 46.

Each clamping plate 44 is provided with a plurality of rubber resistance blocks 45 and a first spring 46. The plurality of rubber resistance blocks 45 and the first spring 46 are sequentially arranged along the width direction of the clamping plate 44. One end of the connecting support plate 43 is fixedly connected to the first mounting frame 8, and the other end of the connecting support plate 43 is slidably connected to the mounting ring 42. The rubber resistance block 45 is slidably connected to the clamping plate 44. The first spring 46 is horizontally arranged. One end of the first spring 46 is fixedly connected to the clamping plate 44, and the other end of the first spring 46 is fixedly connected to the rubber resistance block 45.

[0057] In the screw cap clamping assembly, the mounting ring 42 is fixedly mounted on the outer wall of the multi-jaw chuck 12, playing a connecting and supporting role. The connecting support plate 43 can ensure that during the process of clamping and rotating the water meter cover 3, the movement of the entire screw cap clamping assembly is smoother and more flexible.

[0058] A clamping plate 44 is fixedly mounted on each output end of the multi-claw chuck 12, and these clamping plates 44 are used to directly contact and clamp the water meter cover 3. The rubber contact block 45 can increase the friction between the water meter cover 3 and improve the stability of clamping, and at the same time can also play a certain buffering role to reduce damage to the water meter cover 3. When clamping the water meter cover 3, the first spring 46 can provide a certain elastic buffer, so that the clamping force is more uniform and can adapt to water meter covers 3 of different sizes. The combined design of the rubber contact block 45 and the first spring 46 not only increases the friction and stability of clamping, but also provides buffering protection to reduce damage to the water meter cover 3.

[0059] The bearing seat 6 also includes a V-shaped bearing plate 47 and an end limit plate 48. The end limit plate 48 is detachably connected to the bearing seat 6. Flanges are provided at both ends of the watch case 1. Two end limit plates 48 are provided and are respectively located at both ends of the watch case 1 and abut against the flanges at the ends. The V-shaped bearing plate 47 is located under the water pipes on both sides of the watch case 1.

[0060] The limit clamping assembly 13 includes a double-station screw slide 49, a clamping mounting frame 50 and an inclined mounting plate 51. The clamping mounting frame 50 and the inclined mounting plate 51 are each provided with two and are respectively installed on the two output ends of the double-station screw slide 49. The inclined mounting plate 51 is fixedly connected to the clamping mounting frame 50. The inclined mounting plate 51 is located in the upper half of the outer wall of the watch case 1. The inclined direction of the inclined mounting plate 51 is gradually away from the water pipe from top to bottom. The inclined mounting plate 51 is provided with a plurality of rubber resistance rollers 52 and horizontal sliding frames 53 arranged in sequence along the inclined direction. The rubber resistance roller 52 is installed on the horizontal sliding frame 53. A second spring 54 is provided between the horizontal sliding frame 53 and the inclined mounting plate 51. The two ends of the second spring 54 are respectively fixedly connected to the inclined mounting plate 51 and the horizontal sliding frame 53.

[0061] The bearing seat 6 includes a V-shaped bearing plate and an end stopper plate 48. The V-shaped bearing plate is located under the water pipes on both sides of the case 1 to provide a stable support for the water pipes and ensure that the case 1 is in a stable position during installation. The end stopper plate 48 limits the axial movement of the case 1 to ensure that the water meter does not undergo axial displacement during installation. The detachable connection design of the end stopper plate 48 is convenient for replacement and maintenance, and can meet the installation requirements of water meters of different specifications.

[0062] The limit clamping assembly 13 is composed of a double-station screw slide 49, a clamping mounting frame 50 and an inclined mounting plate 51. When the two inclined mounting plates 51 are brought close to each other, downward pressure is generated, pressing the water meter located in the middle onto the V-shaped bearing plate. The device can adapt to water meters of different models, improving the versatility and applicability of the device. The special inclined design of the inclined mounting plates 51 and the downward pressure generated when they are brought close to each other improve the adaptability to water meters of different models.

[0063] During the clamping process, the rubber abutment roller 52 contacts the outer wall of the case 1 to increase friction and ensure the stability of the clamping. The second spring 54 can provide elastic buffering to evenly distribute the clamping force and can adapt to water meters of different sizes. The combination of the rubber abutment roller 52, the horizontal sliding frame 53 and the second spring 54 further enhances the stability and versatility of the clamping.

[0064] The glass mounting mechanism 7 also includes a displacement drive assembly 55, a second mounting frame 56, an exhaust chamber 57, a vacuum suction nozzle 58, an elastic mounting plate 59 and a rubber resistance pad 60. The displacement drive assembly 55 is mounted on the frame 4, and the second mounting frame 56 is fixedly mounted on the output end of the displacement drive assembly 55. The exhaust chamber 57 and the vacuum suction nozzle 58 are both mounted on the second mounting frame 56. The vacuum suction nozzle 58 is connected to the exhaust chamber 57, and the vacuum suction nozzle 58 is vertically downwardly arranged. The exhaust chamber 57 is connected to the exhaust pump. The elastic mounting plate 59 is located directly below the second mounting frame 56. The elastic mounting plate 59 is elastically connected to the second mounting frame 56, and the rubber resistance pad 60 is fixedly mounted on the bottom of the elastic mounting plate 59.

[0065] The vacuum suction nozzle 58 generates a strong suction force, thereby firmly adsorbing the observation glass 2. During the installation process, the elastic mounting plate 59 can play a buffering role to reduce the impact of the impact force on the components. The displacement drive component 55 is combined with the vacuum suction nozzle 58 to achieve accurate grasping and mobile positioning of the observation glass 2.

[0066] The rubber resistance pad 60 is fixedly installed at the bottom of the elastic mounting plate 59. When the suction force of the vacuum suction nozzle 58 is sufficient, the observation glass 2 is sucked up, and the rubber resistance pad 60 elastically resists the sealing gasket through its own downward force, so that the sealing gasket and the observation glass 2 are displaced synchronously. When installed in place, the vacuum suction nozzle 58 releases adsorption, and the observation glass 2 and the sealing gasket are discharged synchronously. The buffer design of the elastic mounting plate 59 and the ingenious application of the rubber resistance pad 60 not only protect the glass and the sealing gasket, but also ensure the synchronization and accuracy of the two during the installation process.

[0067] A sliding rod 61 is provided on the elastic mounting plate 59, and a third spring 62 is sleeved on the sliding rod 61. The sliding rod 61 is vertically arranged, and the bottom end of the sliding rod 61 is fixedly connected to the elastic mounting plate 59. The upper half of the sliding rod 61 is slidably matched with the second mounting frame 56, and the two ends of the third spring 62 are respectively fixedly connected to the second mounting frame 56 and the elastic mounting plate 59.

[0068] Overall working principle:

[0069] First, place the water meter case 1 to be installed on the V-shaped bearing plate of the bearing seat 6. The double-station screw slide 49 is started to drive the two inclined mounting plates 51 to move closer to each other. The case 1 is firmly pressed on the V-shaped bearing plate. In the glass mounting mechanism 7, the observation glass 2 is sucked up by the vacuum suction nozzle 58. The rubber contact pad 60 at the bottom of the elastic mounting plate 59 elastically contacts the sealing gasket through its own downward force, so that the sealing gasket and the observation glass 2 are displaced synchronously. The observation glass 2 and the sealing gasket are driven by the displacement drive component 55 and placed on the top of the case 1.

[0070] The meter cover installation manipulator of the meter cover installation mechanism 5 moves to the storage position of the water meter cover 3, and the multi-claw chuck 12 stably clamps the water meter cover 3 through the coordinated action of the clamping plate 44, the rubber resistance block 45 and the first spring 46. At this time, the first rotary driver 17 is started to drive the first rotating shaft 18 to rotate. The first rotating shaft 18 drives the adjustment installation cylinder 21 to rotate through the connecting disk 22, and then transmits power to the torque adjustment component 10 through the rotating transmission disk 19.

[0071] When the water meter cover 3 is not installed in place, the second ratchet disc 27 in the torque adjustment assembly 10 drives the adjustment installation cylinder 21 to rotate through the first ratchet disc 26 and the installation disc 25, thereby driving the meter cover clamping assembly 11 connected to the adjustment installation cylinder 21 to rotate synchronously, and realizing the synchronous rotation of the water meter cover 3. The installation disc 25 slides vertically stably along the inner wall of the adjustment installation cylinder 21 through the vertical limit strip 31 and the limit groove 32 to ensure the accuracy and stability of the torque adjustment process. When the water meter cover 3 is installed in place, the adjustment installation cylinder 21 remains stationary. If the capping drive assembly 9 continues to apply torque, the rotation of the second ratchet disc 27 will lift the upper first ratchet disc 26 upward, so that the installation disc 25 overcomes the elastic force of the torque adjustment spring 24 and moves upward, compressing the torque adjustment spring 24, so that the first ratchet disc 26 is separated from the second ratchet disc 27, realizing the transmission separation between the capping drive assembly 9 and the water meter cover 3, and avoiding excessive torque from damaging the water meter cover 3.

[0072] The torque adjustment assembly 10 has two adjustment modes: automatic and manual. When the rotating transmission disk 19 needs to be pushed automatically, the first pusher 33 and the first push rod 34 in the pushing device 28 cooperate to provide a driving force for the rotating transmission disk 19. In the manual adjustment mode, the operator rotates the threaded sleeve 40, and the threaded column 39 moves up and down due to the action of the thread. The locking nut 41 is used to fix the threaded sleeve 40 to prevent it from accidentally rotating. The limiting connecting column 38 and the limiting frame 37 ensure that the threaded column 39 moves vertically, and the pointer 36 and the scale 35 help to intuitively display the adjustment degree. Through this manual adjustment method, the torque size can be adjusted more finely and the movement of the rotating transmission disk 19 can be controlled according to the specific working conditions, further improving the accuracy and adaptability of the torque adjustment.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
