Description

Technical Field

[0001] The invention relates to the technical field of underground well remote water meter assembly, and more specifically to an underground well remote water meter assembly device. Background Art

[0002] The ground well remote water meter can upload the user's water consumption data to the data center in real time through wireless transmission technology, so that the water management department can remotely monitor and grasp the water supply situation of the urban pipe network in real time. This greatly improves the efficiency of water supply management, allowing managers to quickly respond to various water supply problems, such as water leakage, abnormal water pressure, etc., thereby ensuring the stability and safety of water supply. In addition, the remote water meter can realize remote automatic meter reading, which greatly reduces the cost of manual meter reading.

[0003] In the later stage of manufacturing the remote water meter, the water meter needs to be assembled by an assembly device, and the assembly device is used to assemble the case to the meter body. In the process of installing the current case and the meter body, the installation of the two is generally completed by four screws. The operation of placing the screws in the screw holes and rotating them to fix them needs to be completed by manual hand-held tools.

[0047] The rotating mechanism 7 includes a servo motor 71 and a connecting shaft 72. The servo motor 71 is fixedly mounted on the L-shaped seat 4. The connecting shaft 72 is rotatably mounted on the fixed disk 51. The connecting shaft 72 is fixedly connected to the movable end of the reverse rotating component 59. The top end of the connecting shaft 72 passes through the bottom end of the L-shaped seat 4 and is fixedly connected to the output shaft of the servo motor 71. A central gear 73 is fixedly mounted at the bottom end of the connecting shaft 72. The input ends of the four tightening mechanisms 6 are all meshed and connected with the central gear 73. Through the above arrangement, the present invention enables the connecting shaft 72 to rotate with the central gear 73 when the output shaft of the servo motor 71 is controlled to rotate by an external control mechanism, and when the central gear 73 rotates relative to the input ends of the four tightening mechanisms 6, the four tightening mechanisms 6 can be driven to work together. When the rotating disk 55 rotates relative to the fixed disk 51, the four centripetal guide grooves 56 rotate relative to the guide grooves 53.

[0048] In an embodiment of the present invention, the guide groove 53 includes four reciprocating guide grooves 531, the number of which is equal to the four tightening mechanisms 6. The four reciprocating guide grooves 531 are arranged in a circular structure with equal spacing. Any two reciprocating guide grooves 531 are connected through the inner arc groove 532; the reciprocating guide groove 531 includes two inclined guide grooves 5311 arranged in a symmetrical structure, and the eccentric ends of the two inclined guide grooves 5311 are connected through the outer arc groove 5312. The present invention further designs the guide groove 53 so that when the turntable 55 rotates 45° relative to the fixed disk 51, the four centripetal guide grooves 56 rotate 45° relative to the guide groove 53. If the movable column 57 is located in the middle of the inner arc groove 532, the movable column 57 moves from the inner arc groove 532 and the oblique guide groove 5311 to the middle of the outer arc groove 5312 in sequence, so that the four movable columns 57 respectively drive the positioning and clamping components 510 to perform eccentric movement, so that the clamping cavity formed by the gaps of the four positioning and clamping components 510 becomes larger. If the movable column 57 is located in the middle of the outer arc groove 5312, the movable column 57 moves from the outer arc groove 5312 and the oblique guide groove 5311 to the middle of the inner arc groove 532 in sequence, so that the four movable columns 57 respectively drive the positioning and clamping components 510 to perform centripetal movement, so that the clamping cavity formed by the gaps of the four positioning and clamping components 510 becomes smaller.

[0049] In an embodiment of the present invention, a cavity 551 is provided at the bottom of the turntable 55, a central gear 73 is disposed in the cavity 551, a connecting shaft 72 is rotatably connected to the turntable 55, a circular cavity 552 is provided at the top of the turntable 55, and a forward arc groove 553 is provided on the outer edge surface of the turntable 55 relative to the gap position between any two adjacent centripetal guide grooves 56, the depth of the forward arc groove 553 gradually decreases in the clockwise direction, and the gap between the forward arc groove 553 and the limit ring A54 constitutes a limit cavity A.

[0050] In the embodiment of the present invention, a limiting groove 561 is provided on the centripetal guide groove 56, a limiting ring block 562 is movably connected to the limiting groove 561, and the limiting ring block 562 is rotatably connected to the movable column 57. The present invention provides a limiting force for the movable column 57 by setting the limiting ring block 562 to move in the centripetal guide groove 56.

[0051] In an embodiment of the present invention, the forward rotating component 58 is disposed in the limit cavity A; the forward rotating component 58 includes a limit column A581, the limit column A581 is adapted to the shape of the limit cavity A, the limit column A581 is movably disposed in the limit cavity A, and the limit column A581 is elastically connected to the deep part of the forward arc groove 553 through a spring A582. Through the structural design of the forward rotating component 58 of the present invention, under the elastic force of the spring A582, the limit column A581 is located in the middle of the limit cavity A, and when the turntable 55 rotates forward relative to the limit ring A54, the limit column A581 is subjected to the friction resistance of the limit ring A54, which causes the limit column A581 to have a force to move relative to the deep part of the limit cavity A, and will not affect the rotation of the turntable 55 too much. When the turntable 55 rotates reversely relative to the limit ring A54, the limit column A581 is subjected to the friction resistance of the limit ring A54, which causes the limit column A581 to have a force to move relative to the shallow part of the limit cavity A, causing the limit ring A54 to lock the forward arc groove 553 through the limit column A581, so that the turntable 55 cannot rotate reversely. Therefore, the turntable 55 can only rotate forward.

[0052] In an embodiment of the present invention, the reverse rotation component 59 includes a limit ring B591, which is fixed on the circular cavity 552. The limit ring B591 is rotatably connected to the limit swivel 592, and the limit swivel 592 is fixedly connected to the connecting shaft 72. The outer edge surface of the limit swivel 592 is a ring-shaped structure with equal spacing and is provided with a plurality of reverse arc grooves 593. The depth of the reverse arc grooves 593 gradually increases in the clockwise direction. The gap between the reverse arc grooves 593 and the limit ring B591 constitutes a limit cavity B. The limit cavity B is movably connected to a limit column B594, and the limit column B594 is adapted to the shape of the limit cavity B. The limit column B594 is elastically connected to the deep part of the reverse arc groove 593 through a spring B595. Through the mechanism design of the reverse rotation component 59 of the present invention, it can be known from the principle of the forward rotation component 58 that the limit ring 592 can only rotate reversely relative to the limit ring B591, and cannot rotate forwardly relative to the limit ring B591.

[0053] In an embodiment of the present invention, the tightening mechanism 6 includes a side gear 61, which is disposed in the cavity 551. The side gear 61 is meshed and connected with the center gear 73. The side gear 61 is rotatably connected with the cavity 551 through a rotating shaft 62. The bottom end of the rotating shaft 62 passes through the bottom end of the turntable 55 and is fixedly provided with a mounting block 63. A screwdriver 64 is fixedly installed at the bottom end of the mounting block 63. The present invention adopts the structural design of the positioning clamping mechanism 5, the tightening mechanism 6 and the rotating mechanism 7, so that when the output shaft of the servo motor 71 is controlled to rotate in the forward direction by the external control mechanism, the connecting shaft 72 and the central gear 73 rotate. Since the limit rotating ring 592 cannot rotate in the forward direction relative to the limit ring B591, the connecting shaft 72 drives the limit rotating ring 592 and the limit ring B591 to rotate in the forward direction together, and the limit ring B591 drives the turntable 55 to rotate in the forward direction, so that the four centripetal guide grooves 56 rotate, so that the gap position between the centripetal guide groove 56 and the guide groove 53 changes, and the size of the clamping cavity formed by the gap of the control positioning clamping assembly 510 changes. It is used to clamp and loosen the ground well remote water meter; when the output shaft of the servo motor 71 is controlled to rotate in reverse by the external control mechanism, since the turntable 55 cannot rotate in reverse, the connecting shaft 72 drives the limit ring 592 to rotate in reverse relative to the limit ring B591, so that the central gear 73 rotates in reverse relative to the turntable 55, thereby driving the four side gears 61 to rotate, so that the rotating shaft 62, the mounting round block 63, and the screwdriver 64 rotate in reverse, and the movable end of the screw rod lifting mechanism 3 is controlled to rise and fall by the external control mechanism, so that the four screwdrivers 64 tighten the four screws on the ground well remote water meter at the same time, completing the assembly of the ground well remote water meter.

[0054] In the embodiment of the present invention, the positioning clamping assembly 510 includes a gravity column 5101, a slide groove 5102 is provided in the gravity column 5101, a slider 5103 is slidably connected to the slide groove 5102, a slide rod 5100 is fixedly provided at the top of the slider 5103, the top of the slide rod 5100 passes through the slider 5103 and is rotatably connected to a connecting rod 5104, the top of the connecting rod 5104 is fixedly connected to the bottom of the movable column 57, and a clamping block 5105 is fixedly installed on the gravity column 5101. In the embodiment of the present invention, the present invention makes the bottom end of the gravity column 5101 keep in contact with the conveying end surface of the conveyor belt mechanism 1 under the gravity of the gravity column 5101 itself through the above arrangement, and when the screw rod lifting mechanism 3 is controlled to rise and fall by the external control mechanism, the movable column 57 rises and falls to drive the connecting rod 5104, the slide rod 5100 and the slider 5103 to rise and fall, and the slider 5103 slides relative to the slide groove 5102.

[0055] A ball groove 5106 is provided at the bottom of the gravity column 5101, and a steel ball 5107 is movably connected in the ball groove 5106. Through the above arrangement, when the size of the clamping cavity of the four clamping blocks 5105 changes, the steel ball 5107 rolls along the conveying end surface of the conveyor belt mechanism 1, reducing the wear of the conveying end surface of the conveyor belt mechanism 1.

[0056] In the embodiment of the present invention, the clamping block 5105 is a regular polygonal structure, and any side of the clamping block 5105 is provided with an arc-shaped clamping groove 5108. Fig.10 As shown, the size of the gap between any two clamping blocks 5105 is adapted to the size of the connecting ends at both ends of the ground well remote water meter, so that the clamping cavity formed by the four clamping blocks 5105 is reduced. When the ground well remote water meter is clamped, the reaction force of the ground well remote water meter on the clamping block 5105 can make the clamping block 5105 drive the gravity column 5101 and the slider 5103 to rotate relative to the connecting rod 5104, so that the arc-shaped clamping grooves 5108 of the four clamping blocks 5105 are tightly attached to the surface of the ground well remote water meter, and the corners of the clamping block 5105 position and straighten the ground well remote water meter with a certain inclination angle on the conveying end face of the conveyor belt mechanism 1, so that the four screwdrivers 64 can tighten the four screws on the ground well remote water meter at the same time.

[0057] Working principle: This embodiment provides a ground well remote water meter assembly device. When in use, the conveyor belt mechanism 1 transports the ground well remote water meter to be assembled, and the output shaft of the servo motor 71 is controlled by an external control mechanism to rotate 45° in the forward direction, and the connecting shaft 72 and the central gear 73 rotate 45°. Since the limit swivel 592 cannot rotate forward relative to the limit ring B591, the connecting shaft 72 drives the limit swivel 592 and the limit ring B591 to rotate 45° forward together, and the limit ring B591 drives the turntable 55 to rotate 45° relative to the fixed plate 51, and the four centripetal guide grooves 56 rotate 45° relative to the guide groove 53, and the movable column 57 moves from the outer arc groove 5312 and the inclined guide groove 5311 to the middle position of the inner arc groove 532 in turn, and drives the positioning clamping assembly 510 to rotate in the forward direction respectively. The steel ball 5107 rolls along the conveying end surface of the conveyor belt mechanism 1, so that the clamping cavity formed by the gaps of the four positioning clamping components 510 becomes smaller to clamp and position the ground well remote water meter. When the clamping cavity formed by the four clamping blocks 5105 is reduced to clamp the ground well remote water meter, the reaction force of the ground well remote water meter on the clamping block 5105 can make the clamping block 5105 drive the gravity column 5101 and the slider 5103 to rotate relative to the connecting rod 5104, so that the arc-shaped clamping grooves 5108 of the four clamping blocks 5105 are in close contact with the surface of the ground well remote water meter, and the corners of the clamping block 5105 position and straighten the ground well remote water meter with a certain inclination angle on the conveying end surface of the conveyor belt mechanism 1, so that the four screwdrivers 64 can tighten the four screws on the ground well remote water meter at the same time;

[0058] The output shaft of the servo motor 71 is controlled to rotate in reverse through an external control mechanism. Since the turntable 55 cannot rotate in reverse, the connecting shaft 72 drives the limit rotating ring 592 to rotate in reverse relative to the limit ring B591, so that the central gear 73 rotates in reverse relative to the turntable 55, thereby driving the four side gears 61 to rotate, so that the rotating shaft 62, the mounting round block 63, and the screwdriver 64 rotate in reverse. The movable end of the screw rod lifting mechanism 3 is controlled to descend through an external control mechanism, and the movable column 57 descends to drive the connecting rod 5104, the sliding rod 5100, and the sliding block 5103 to descend. The sliding block 5103 slides relative to the sliding groove 5102, so that the four screwdrivers 64 tighten the four screws on the ground well remote water meter at the same time, completing the assembly of the ground well remote water meter. The movable end of the screw rod lifting mechanism 3 is controlled to rise to the initial position through an external control mechanism, and the screwdriver 64 is separated from the screws.

[0059] The output shaft of the servo motor 71 is controlled by an external control mechanism to rotate another 45° in the forward direction, and the movable column 57 moves from the inner arc groove 532 and the inclined guide groove 5311 to the middle position of the outer arc groove 5312 in sequence, so that the four movable columns 57 respectively drive the positioning clamping components 510 to perform eccentric movement, so that the clamping cavity formed by the gaps of the four positioning clamping components 510 becomes larger and disengaged from the ground well remote water meter, and the four positioning clamping components 510 return to their initial positions, so that when the device adjusts the clamping cavity formed by the four clamping blocks 5105 to scale, the output shaft of the servo motor 71 rotates a total of 90°, and the four screwdrivers 64 also rotate 90°, so that the tightening positions of the four screwdrivers 64 are constant.

[0060] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
