Description

Technical Field

[0001] This utility model relates to the field of water meter testing technology, specifically to an independent running lap testing device. Background Technology

[0002] Both electronic and electromechanical water meters contain electronic modules. These modules connect to the impeller in the water meter using either magnetic or non-magnetic means, thereby monitoring the number of impeller rotations and calculating water consumption. Therefore, ensuring the proper functioning of the electronic module is essential for guaranteeing the water meter's quality. After the electronic module is manufactured, a rotation test is required to check for any issues that might affect its accuracy, such as missing rotations, thus ensuring the module's precise operation.

[0003] Currently, existing testing structures, such as the device disclosed in patent document CN201397184Y for testing the water metering performance of electronic modules in non-magnetic water meters, include a stepper motor and signal processing circuitry within the housing. A disc with a metal patch is mounted on the rotor of the stepper motor. Two grooves are located above the disc on the housing, and the signal processing circuitry is electrically connected to the stepper motor. During testing, the LC sensor of the electronic module under test is placed in the groove. The stepper motor drives the disc to rotate, simulating the rotation of an impeller. When the metal patch rotates to the bottom of the groove, the LC sensor detects the rotation signal of the metal patch, allowing the electronic module under test to process and obtain the number of rotations of the metal patch. Simultaneously, the signal processing circuit displays the number of rotations of the stepper motor on a display screen. By comparing the number of rotations monitored by the electronic module with the actual number of rotations of the stepper motor, the metering accuracy of the electronic module under test can be determined. Although the above structure can meet the testing requirements of electronic modules, it can only adapt to the testing needs of a single product. For products with different sizes and specifications and different testing requirements, it is necessary to develop additional testing equipment, which results in a waste of resources and higher testing costs.

This device comprises several independently arranged simulation components within a test chamber. Each simulation component includes a drive motor, with the motor shaft extending upwards out of the test chamber. A replaceable simulation rotating block is mounted on each shaft, allowing for the selection and replacement of simulation rotating blocks with different functions depending on whether magnetism is required. Furthermore, the test chamber is equipped with a height-adjustable lifting platform with test stations corresponding to each simulation component. By adjusting the height of the lifting platform and replacing the simulation rotating blocks, the device can meet the lap testing requirements of electronic modules of different sizes and specifications. Moreover, each simulation component operates independently, enabling simultaneous independent testing of multiple products, improving testing efficiency, reducing testing costs, and avoiding resource waste.

[0026] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0027] Figure 1 This is a structural diagram of an embodiment of the independent running lap testing device of this utility model; Figure 2 This is a structural diagram of the independent running lap testing device of this utility model after the lifting platform has been disassembled. Figure 1 and Figure 2 As shown, the independent running lap test device provided in this embodiment includes: a test box 1, several sets of simulation components 2, and a lifting platform 3.

[0028] Specifically, the test box 1 has an installation cavity, which provides internal space for the subsequent concealed installation of the simulation components 2 and improves the external protection capability. The top of the test box 1 is a horizontally arranged support plate 11, through which the drive motor 21 of each simulation component 2 is installed. At the same time, it also provides an installation and support foundation for the subsequent lifting platform 3.

[0029] Specifically, several groups of simulation components 2 are arranged independently, ensuring that the operation of each group of simulation components 2 does not interfere with each other, thus providing conditions for the simultaneous testing of multiple electronic modules 6. Each group of simulation components 2 includes a signal processing circuit, a drive motor 21, and a simulated rotating block 22. The signal processing circuit and the drive motor 21 are both installed inside the mounting cavity, achieving concealed installation of the simulation components 2 and improving external protection capabilities. At the same time, the drive motor 21 is fixed to the bottom surface of the support plate 11, with its shaft vertically upward, passing through the support plate 11 and extending outside the support plate 11, providing conditions for the subsequent installation of the simulated rotating block 22 on the shaft of each drive motor 21. At this time, a detachable analog rotating block 22 is coaxially mounted on one end of each drive motor 21 extending outside the support plate 11. The analog rotating block 22 is provided with a magnet or metal patch, which can adapt to the testing requirements of the electronic module 6 with or without magnetism. It is worth noting that since the scheme for the signal processing circuit to count the number of rotations of the drive motor 21 has been disclosed in patent document CN201397184Y and belongs to the prior art in the industry, its counting structure and method will not be described again in this embodiment.

[0030] Specifically, the lifting platform 3 is positioned parallel and spaced above the support plate 11, ensuring that the distance between the lifting platform 3 and the support plate 11 is uniform at all points, thus guaranteeing stability during testing. Furthermore, several test stations 311 are provided on the lifting platform 3, each corresponding to a set of simulated components 2. Electronic modules 6 to be tested are placed at the test stations 311, allowing each module to be tested to be paired with an independent simulated component 2 for testing. This enables simultaneous testing of multiple products, improving testing efficiency and ensuring that test results do not interfere with each other, resulting in higher accuracy. Simultaneously, the lifting platform 3 moves vertically relative to the support plate 11, allowing it to adjust its distance from the support plate 11, thereby adjusting the distance between it and the simulated rotating block 22. This meets the testing requirements of products of different sizes and specifications, eliminating the need for structural disassembly and assembly, making the structure more flexible, and avoiding the high testing costs associated with designing a dedicated testing device for each product, thus preventing resource waste.

[0031] More specifically, the lifting platform 3 includes a workstation plate 31 and a lifting driver 32. The workstation plate 31 is positioned parallel and spaced above the support plate 11, with several test stations 311 mounted on it. The workstation plate 31 carries the electronic module 6 to be tested. Simultaneously, lifting drivers 32 are arranged vertically on both sides of the workstation plate 31 and mounted on the support plate 11. Preferably, the lifting driver 32 is a linear electric actuator, providing stable and reliable linear power and stable support when stationary, thus maintaining the stability of the workstation plate 31 during testing and ensuring test accuracy.

[0032] More specifically, a guide assembly 4 is provided between the support plate 11 and the workstation plate 31 to guide the lifting of the lifting platform 3. The guide assembly 4 includes a guide sleeve 41 and a guide rod 42. Several vertically penetrating guide holes are provided on the outer side of the workstation plate 31, and a guide sleeve 41 is coaxially installed in each guide hole. The upper end of the guide rod 42 is slidably inserted into the guide sleeve 41, and the lower end of the guide rod 42 is installed on the support plate 11. This allows the workstation plate 31 to be guided during lifting by the sliding of the guide sleeve 41 on the guide rod 42, further improving the stability of the workstation plate 31 during lifting and testing.

[0033] More specifically, an adapter block 23 is installed on the shaft of each drive motor 21. Preferably, the adapter block 23 has a cylindrical structure to facilitate its machining. An insertion hole is provided at one end of the adapter block 23, which is coaxially fitted onto the shaft of the corresponding drive motor 21, allowing the drive motor 21 to drive the adapter block 23 to rotate. Furthermore, the simulated rotating block 22 is detached and installed on the adapter block 23, allowing the drive motor 21 to mount the simulated rotating block 22 via the adapter block 23. When replacing the simulated rotating block 22, it is only necessary to remove it from the adapter block 23, avoiding direct operation on the shaft of the drive motor 21, thus reducing the impact on the drive motor 21. Additionally, the adapter block 23 expands the contact area between the shaft of the drive motor 21 and the simulated rotating block 22, making the simulated rotating block 22 more stable after installation.

[0034] Figure 3 This is a structural diagram of the adapter block according to a preferred embodiment of the present invention; Figure 4 This is a structural diagram of a simulated rotating block according to a preferred embodiment of the present invention. Figures 2 to 4 As shown, a first mating surface 231 is provided at the end of the adapter block 23 facing away from the shaft of the drive motor 21, and a second mating surface 221 is provided at the end of the simulated rotating block 22, so that the simulated rotating block 22 can be connected to the first mating surface 231 of the adapter block 23 through the second mating surface 221. Furthermore, a first center hole 232 and several positioning holes 233 are provided on the first mating surface 231, and a second center hole 222 and several positioning pins 223 are provided on the second mating surface 221. This allows the simulated rotating block 22 to be connected to the adapter block 23 through the first center hole 232 and the second center hole 222, improving the stability of the assembly. Simultaneously, inserting the positioning pins 223 one by one into the corresponding positioning holes 233 achieves rapid positioning, facilitating disassembly and replacement, and also provides circumferential limiting, ensuring that the adapter block 23 can synchronously drive the simulated rotating block 22 to rotate, thus ensuring the accuracy of the test.

[0035] More specifically, a magnet is also provided in the first central hole 232, and a magnetic suction component is provided in the second central hole 222 to magnetically connect with the magnet. This allows the simulated rotating block 22 to be magnetically connected to the adapter block 23 through the magnet and the magnetic suction component, making the disassembly and replacement of the simulated rotating block 22 more convenient. Preferably, the magnetic suction component can be a magnet or a metal part that can be magnetically attracted, such as an iron block. The appropriate magnetic suction component can be selected according to the actual needs, making the operation more convenient.

[0036] More specifically, the shaft of the drive motor 21 is connected to the adapter block 23 by a key connection. At this time, the shaft of the drive motor 21 and the adapter block 23 can be connected by a flat key or a spline connection. The appropriate key connection method is selected according to the actual use requirements. This achieves circumferential limiting between the shaft of the drive motor 21 and the adapter block 23, ensuring stable and reliable transmission of the power of the drive motor 21 to the adapter block 23, and realizing the synchronous rotation of the adapter block 23.

[0037] More specifically, in addition to the key connection method mentioned above, the shaft of the drive motor 21 and the adapter block 23 are also connected by a locking hole 234 with a connecting socket on the side wall of the adapter block 23. A locking screw is installed in the locking hole 234. By tightening the locking screw, one end of the locking screw extends into the socket and abuts against the shaft of the drive motor 21. The end of the locking screw presses against the shaft of the drive motor 21, thereby achieving circumferential limiting of the adapter block 23 and the shaft of the drive motor 21, preventing slippage during the test and ensuring the accuracy of the test structure.

[0038] More specifically, the test box 1 has a modular structure. In this case, the test box 1 is a rectangular box, including a front panel, a rear panel, a left panel, and a right panel. All four panels are mounted on a base plate, enabling assembly and simplifying manufacturing. Simultaneously, slide rails are provided at both ends of the support plate 11 and between it and the left and right panels of the test box 1. These two slide rails are arranged horizontally and parallel to each other, allowing the support plate 11 to slide horizontally along the two slide rails, thus enabling it to be pulled out. This facilitates wire connection without disassembling the drive motor 21, making wiring easier. It also allows for subsequent maintenance of the drive motor 21 without completely disassembling the support plate 11 and other structures, making operation more convenient. Meanwhile, the bottoms of the front and rear side panels of test box 1 are hinged to the bottom of test box 1. The front and rear sides of test box 1 can be opened by flipping the front and rear side panels, avoiding obstruction of the drive motor 21 that moves with the support plate 11 during sliding. This ensures that the drive motor 21 can be moved laterally outside the test box 1, facilitating wiring and subsequent maintenance. It is worth noting that the slide rail includes a guide rail and a slider. The guide rail is fixedly installed on the left and right side panels, and the slider is slidably set on the corresponding guide rail. Furthermore, the slider is installed near the center of the support plate 11, allowing the support plate 11 to slide a predetermined distance along the front side and a predetermined distance along the rear side of test box 1. This satisfies the wiring and maintenance requirements of the analog components 2 on the front and rear sides of the support plate 11, resulting in a more reasonable structural design.

[0039] More specifically, latches 5 are provided on the top of the front and rear side panels of the test chamber 1, respectively, between them and the front and rear sides of the support plate 11. These latches 5 enable quick connection or separation of the front and rear side panels from the support plate 11, ensuring the stability of both the overall structure of the test chamber 1 and the support plate 11 during testing, thus guaranteeing accurate test results. It is worth noting that the latches 5 are commercially available structures; a suitable latch 5 can be selected based on specific needs. Therefore, the structure of the latches 5 will not be described in detail here.

[0040] The independent lap testing device provided in this embodiment includes a test box 1, several sets of simulation components 2, and a lifting platform 3. By installing several sets of relatively independent simulation components 2 in the test box 1, and installing the lifting platform 3 with several test stations 311 above the test box 1 in a liftable manner, and each set of simulation components 2 includes a drive motor 21 with a rotating shaft extending out of the test box 1, and a simulation rotating block 22 is detached and installed on the rotating shaft of the drive motor 21. By adjusting the lifting of the lifting platform 3 and replacing different types of simulation rotating blocks 22, it can adapt to the testing of products of different sizes and specifications. There is no need to design a separate test rotor, which reduces costs, avoids waste of resources, and also enables several sets of simulation components 2 to independently realize the individual lap testing of several products, meeting the needs of testing multiple products at the same time, and improving testing efficiency.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
