Description

Technical Field

[0001] This utility model relates to the field of ultrasonic gas meter manufacturing technology, specifically to an assembly equipment for the flow guide plate of an ultrasonic gas meter. Background Technology

[0002] An ultrasonic gas meter is a high-precision, intelligent instrument that uses the ultrasonic time-difference principle to measure gas flow. Its core measuring components include a pair of precisely symmetrically mounted ultrasonic transducers and a flow guide plate that forms a specific airflow channel. The flow guide plate is typically injection-molded from plastic and has precisely molded flow channels inside. Its functions are twofold: first, to guide the gas to form a stable, vortex-free flow field; and second, to provide a precise reflection path for the ultrasonic signal, ensuring that the ultrasonic waves can be accurately and efficiently received between the transducers.

[0003] The installation quality of the gas meter's flow guide plate directly determines the metering accuracy and consistency of the ultrasonic gas meter. The assembly of this component is a core technological process ensuring accuracy. Typically, the assembly of the flow guide plate in ultrasonic gas meters is done manually, requiring high precision in assembly position and flatness of the component itself. Manual assembly is difficult for employees to guarantee consistency, resulting in a high rate of accuracy errors and high labor costs. With the continuous development of ultrasonic gas meter technology and the significant increase in market sales, there is an urgent need to automate the assembly process, replacing manual operations that are difficult to perform.

[0004] To address the aforementioned issues, Chinese Patent Application No. 202320337573.8 discloses a flow channel separator installation device. The disclosed installation device includes a press frame, characterized in that: a cylinder is installed on the press frame, a punch is provided at the front end of the cylinder, a pressure plate is connected to the front end of the punch, a comb-shaped positioning component for fixing the separator is provided below the pressure plate, and columnar positioning components for fixing the flow channel are provided around the outer periphery of the comb-shaped positioning component. Chinese Patent Application No. 201621327091.0 discloses an assembly device for a gas flow path rectifier plate of an ultrasonic gas meter. The disclosed rectifier plate assembly device has a limiting groove for fixing the gas flow path in the main body of the device, multiple threaded holes for fixing a guide rail in the middle of the main body, and a double-rod cylinder fixed to the other end of the main body. The double-rod cylinder is fixed to a rectifier plate clamping block, which has the same number of grooves as the rectifier plates. The rectifier plate clamping block is fixed to a slider, and the guide rail is fixed to the main body of the device. Multiple rectifier plates are installed inside the rectifier plate clamping block. The gas flow path is placed in the limiting groove of the main body and connected to the double-rod cylinder. Simultaneously, multiple rectifier plates are placed into the gas flow path, with an interference fit between the multiple rectifier plates and the gas flow path. When the double-rod cylinder pulls out the rectifier plate clamping block, the multiple rectifier plates remain in the gas flow path, completing the assembly.

[0005] Traditional methods rely entirely on manual operation, which suffers from low assembly accuracy, difficulty in ensuring the flatness of the guide vane, and poor operational consistency. This directly leads to deviations in the ultrasonic signal path, resulting in unstable gas metering accuracy and a high product defect rate. Furthermore, manual operation is inefficient, labor-intensive, and susceptible to quality risks due to staff turnover and fatigue, leading to continuously rising labor costs. The aforementioned existing technology uses punches and pressure plates for press-fitting. This "impact-type" assembly method may not be able to accurately control the depth and orientation of the guide vane insertion into the channel module, posing a risk of damage to parts or improper assembly, especially for guide vanes requiring high-precision tight fit. Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide an ultrasonic gas meter assembly device that enables bidirectional and precise positioning and limiting of the diverting plate during the assembly process, thereby achieving stable and reliable ultra-high precision assembly.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an ultrasonic gas meter complete unit diverter assembly device, including a control console and a bracket set on the control console. The control console is provided with a positioning component for positioning the diverter placement position. The positioning component includes a positioning seat and several positioning plates set on the positioning seat. A positioning gap for placing the diverter is provided between adjacent positioning plates. The bracket is provided with a driving mechanism, and a channel module for assembling with the diverter is fixed on the driving mechanism. The control console is provided with a pushing component for pushing the diverter into the channel module.

[0008] As a preferred embodiment of this utility model, several positioning plates are disposed at opposite ends of the positioning seat, and the positioning gaps between adjacent positioning plates at both ends correspond to each other.

[0009] As a preferred embodiment of this utility model, the positioning seat is provided with positioning grooves at both ends, and the two positioning grooves are respectively located on the outer side of the positioning plate at the corresponding ends.

[0010] As a preferred embodiment of the present invention, the positioning component further includes a positioning platform for fixing the positioning seat. The positioning platform is disposed on the control console and is provided with a plurality of positioning pins arranged around the positioning seat.

[0011] As a preferred embodiment of the present invention, the pushing assembly includes a pushing cylinder and a pushing shaft connected to the output end of the pushing cylinder, and the end of the pushing shaft is provided with a push block for pushing the guide plate.

[0012] As a preferred embodiment of this utility model, the control console is provided with a mounting base, the push cylinder is mounted on the mounting base, and the push shaft passes through the mounting base and is connected to the push block.

[0013] As a preferred embodiment of this utility model, the positioning platform is provided with a through hole, and the middle part of the positioning seat is provided with a push block hole corresponding to the through hole, and the push block passes through the through hole and the push block hole respectively.

[0014] As a preferred embodiment of the present invention, the driving mechanism includes a driving cylinder and a driving seat connected to the output shaft of the driving cylinder. The bottom of the driving seat is provided with a mounting block for mounting the channel module, and the mounting block is located directly above the positioning seat.

[0015] As a preferred embodiment of this utility model, the drive seat is provided with a fixing screw for fixing the mounting block, and the fixing screw passes through the drive seat and is connected to the mounting block.

[0016] As a preferred embodiment of this utility model, the mounting block is provided with a mounting groove, the channel module is disposed in the mounting groove, and the two ends of the mounting block are provided with positioning elements for positioning the channel module.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The positioning component uses a positioning seat and multiple positioning plates to form a precise positioning gap, enabling pre- and independent precise positioning of multiple drainage plates. The drive mechanism controls the channel module to move downward, and the push component precisely pushes the drainage plates from the bottom to the slots of the channel module at the moment of assembly, forming a two-way precise positioning system. This ensures the precise alignment and smooth insertion of the drainage plates into the slots, effectively avoiding tilting, jamming, or disturbance problems that may occur in existing technologies. It ensures that the drainage plates are placed in the correct position, avoids deviations in manual operation, and improves the repeatability and consistency of assembly. 2. Furthermore, the pusher block is driven by the pusher cylinder located directly below the guide plate to push the guide plate out of the positioning gap. This bottom-up pushing method, together with the downward pressing action of the channel module, forms a combined force, ensuring accurate alignment of the guide plate and improving the assembly quality. 3. Positioning pins are set on the positioning platform to further fix the positioning seat, prevent displacement, enhance overall stability, and fix the push component through the mounting base. The push shaft and push block are stably connected to ensure a smooth and reliable pushing process and avoid damage to the guide plate. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown, an ultrasonic gas meter assembly device for a guide plate includes a control console 1 and a bracket 3 mounted on the control console 1. The control console 1 is provided with a positioning component 2 for positioning the guide plate 6. The positioning component 2 includes a positioning seat 202 and a plurality of positioning plates 203 mounted on the positioning seat 202. A positioning gap 2031 for placing the guide plate 6 is provided between adjacent positioning plates 203. The bracket 3 is provided with a driving mechanism 4, and a channel module 5 for assembling with the guide plate 6 is fixed on the driving mechanism 4. The control console 1 is provided with a pushing component 205 for pushing the guide plate 6 into the channel module 5.

[0021] Furthermore, the positioning component 2 is mounted on the control console 1. The drive mechanism 4 and the pushing component 205 are both electrically connected to the control console 1. The control console 1 controls the movement of the drive mechanism 4 and the pushing component 205. By setting a positioning plate 203 with a positioning gap 2031, an independent and precise accommodating space is provided for each guide plate 6, ensuring that the position and flatness of the guide plate 6 can be pre-corrected before assembly, laying a solid foundation for subsequent high-precision assembly and overcoming the randomness of manual placement. The drive mechanism 4 is responsible for precisely pressing the channel module 5 down to the assembly position, while the pushing component 205 pushes the guide plate 6 upward into the channel module 5 from the bottom. This coordinated action of pressing from above and below ensures that the guide plate 6 can enter the slot of the channel module 5 smoothly, vertically, and without disturbance, effectively avoiding the damage to parts caused by "impact" pressing or the positional disturbance caused by "clamping" extraction in the prior art, thereby achieving extremely high assembly accuracy and reliability.

[0022] Several positioning plates 203 are disposed at opposite ends of the positioning base 202, and the positioning gaps 2031 between adjacent positioning plates 203 at both ends correspond to each other. Furthermore, the positioning plates 203 are vertically arranged, and the positioning gaps 2031 are arranged along the height direction of the positioning plates 203. The number and position of the positioning plates 203 at both ends of the positioning base 202 are the same, that is, the positioning plates 203 at both ends are symmetrically arranged, so that the positioning gaps 2031 at both ends are also symmetrically arranged, thereby realizing the pre-correction of the position of the drainage plate 6.

[0023] The positioning base 202 has positioning grooves 2021 at both ends. The two positioning grooves 2021 are located on the outer side of the positioning plate 203 at the corresponding ends. Furthermore, when the channel module 5 moves down onto the positioning base 202, the channel module 5 is positioned by the positioning grooves 2021 to ensure that the groove of the channel module 5 corresponds to the guide plate 6, thereby ensuring the assembly accuracy of the guide plate 6.

[0024] The positioning assembly 2 also includes a positioning platform 201 for fixing the positioning seat 202. The positioning platform 201 is set on the control console 1, and the positioning platform 201 is provided with a plurality of positioning pins 2011 arranged around the positioning seat 202. Furthermore, the positioning platform 201 is a flat plate structure, the positioning seat 202 is set on the positioning platform 201, and the positioning pins 2011 are fixedly set on the upper surface of the positioning platform 201. The plurality of positioning pins 2011 surround to form a positioning space for accommodating the positioning seat 202. The positioning platform 201 and the positioning pins 2011 constitute a high-precision reference platform, ensuring that the installation position of the entire positioning seat 202 on the equipment is absolutely accurate and stable, preventing any slight displacement during operation, thereby ensuring the uniformity and repeatability of the reference throughout the assembly process.

[0025] The pushing assembly 205 includes a pushing cylinder 2053 and a pushing shaft 2051 connected to the output end of the pushing cylinder 2053. The end of the pushing shaft 2051 is provided with a push block 2052 for pushing the guide plate 6. Furthermore, the pushing cylinder 2053 is vertically arranged, thereby driving the pushing shaft 2051 to move in the vertical direction, thereby ensuring that the push block 2052 will not deviate during the upward movement. In addition, the size of the push block 2052 is the same as the width formed by several positioning plates 203, thereby ensuring that the push block 2052 can push all the guide plates 6 on the positioning seat 202 downward at the same time.

[0026] The control console 1 is equipped with a mounting base 204. The push cylinder 2053 is mounted on the mounting base 204, and the push shaft 2051 passes through the mounting base 204 and is connected to the push block 2052. The mounting base 204 is fixedly installed in the control console 1. The mounting base 204 provides a solid and stable support for the push cylinder 2053 and the push shaft 2051, ensuring that the movement trajectory of the push shaft 2051 is accurate and without shaking. This further ensures that the push block 2052 can vertically and accurately push the guide plate 6 into the predetermined position, which is a key structural guarantee for achieving 0.02mm high-precision assembly.

[0027] The positioning platform 201 is provided with a through hole 2012, and the positioning seat 202 is provided with a push block hole 2022 corresponding to the through hole 2012 in the middle. The push block 2052 passes through the through hole 2012 and the push block hole 2022 respectively. Furthermore, the dimensions of the through hole 2012 and the push block hole 2022 are matched to ensure that the push block 2052 can pass through the positioning platform 201 and the positioning seat 202, while providing a precise guide channel for the movement of the push block 2052. The through hole 2012 and the push block hole 2022 work together to constrain the movement path of the push block 2052, making it strictly aligned with the guide plate 6 directly above, effectively preventing deflection during the pushing process and ensuring the accuracy of the pushing operation.

[0028] The drive mechanism 4 includes a drive cylinder 401 and a drive seat 402 connected to the output shaft of the drive cylinder 401. The bottom of the drive seat 402 is provided with a mounting block 403 for mounting the channel module 5. The mounting block 403 is located directly above the positioning seat 202. Furthermore, the drive cylinder 401 is oriented downwards. The drive cylinder 401 controls the drive seat 402 to drive the mounting block 403 and the channel module 5 to move downwards, forming a rigid and well-guided downward pressing system. The drive cylinder 401 provides stable downward pressure. The drive seat 402 and the mounting block 403 accurately guide the channel module 5 to the assembly position corresponding to the lower guide plate 6, ensuring the accuracy of the alignment between the channel module 5 and the guide plate 6.

[0029] The drive base 402 is provided with a fixing screw 4021 for fixing the mounting block 403. The fixing screw 4021 passes through the drive base 402 and is connected to the mounting block 403. The fixing screw 4021 ensures that the mounting block 403 is fixed on the drive base 402, and avoids the mounting block 403 from shaking during the downward movement, so as to prevent the channel module 5 and the diverting plate 6 from being misaligned.

[0030] The mounting block 403 is provided with a mounting groove 4031, in which the channel module 5 is set. The mounting block 403 is provided with positioning elements 4032 at both ends for positioning the channel module 5. Furthermore, the positioning elements 4032 are connected to the channel module 5 for precise positioning of the installation position of the channel module 5. The mounting groove 4031 and the positioning elements 4032 work together to achieve rapid and accurate positioning and clamping of the channel module 5 in the drive mechanism 4, simplifying the replacement or adjustment process of the channel module 5, improving the convenience and adaptability of the equipment, and ensuring that the position of the channel module 5 remains fixed during the assembly process.
