Technical Field
[0001] This utility model relates to the field of testing tooling technology, and in particular to a high-efficiency testing tooling for testing photoelectric water meter modules. Background Technology
[0002] In modern smart water systems, photoelectric water meter modules are core components, and their reliability and accuracy are crucial. To ensure these modules meet quality standards, extensive and rigorous testing is required. A highly efficient testing fixture for photoelectric water meter modules has emerged, designed to provide a more convenient, efficient, and accurate solution for testing these modules, adapting to the growing market demand for smart water meters and increasingly stringent product quality control requirements.
[0003] Traditional photoelectric water meter module testing fixtures often employ simple manual operation in their mechanical structure. For example, the photoelectric emission source and receiving device are manually aligned with the water meter module, and the position and angle are adjusted based on human experience. Technically, they are mainly based on simple circuit connectivity and basic optical signal detection, lacking automated collaborative mechanisms. This traditional fixture design requires significant manual intervention during testing; from module placement and detection device positioning to data reading and recording, the entire process relies on manual operation.
[0004] However, this traditional testing fixture has a problem: low testing efficiency. Because it relies entirely on manual operation, each test requires operators to carefully adjust the position between the photoelectric emission source and the module to ensure precise alignment—a time-consuming and labor-intensive process. Furthermore, manual operation makes it difficult to guarantee consistency and speed in each adjustment, leading to a significant increase in time required for batch testing of photoelectric water meter modules. This makes it difficult to meet the demands of rapid product testing in large-scale production, impacting production efficiency and the company's capacity expansion. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-efficiency testing fixture for testing photoelectric water meter modules. It aims to improve the problem that traditional testing fixtures are inefficient and require operators to carefully adjust the position between the photoelectric emission source and the module for each test to ensure accurate alignment, which is time-consuming and labor-intensive.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency testing fixture for testing photoelectric water meter modules, comprising a workbench, a cylinder fixedly connected inside the workbench, a movable plate fixedly connected to the output end of the cylinder, an L-shaped plate fixedly connected to the outer wall of the movable plate, a branch rod rotatably connected inside the L-shaped plate, a pressure block rotatably connected to one end of the branch rod, an auxiliary rod rotatably connected inside the L-shaped plate, a photoelectric emission plate fixedly connected to the lower surface of the pressure block, a rotating rod rotatably connected inside the pressure block, a support rotatably connected to one end of the rotating rod, a limit block fixedly connected to the upper surface of the workbench, and a photoelectric receiver fixedly connected inside the workbench.
[0007] Furthermore, the workbench is rotatably connected to a rotating shaft, a worm gear is fixedly connected to the middle of the rotating shaft, a rotating plate is rotatably connected to the workbench, a worm wheel is fixedly connected to the outer wall of the rotating plate, the worm wheel meshes with the worm gear, an arc-shaped sliding groove is opened inside the rotating plate, and a clamping assembly is provided inside the rotating plate.
[0008] Furthermore, the clamping assembly includes a sliding block and a clamping plate, the lower surface of the sliding block is slidably connected to the interior of the rotating plate, and the outer wall of the clamping plate is fixedly connected to one side of the outer wall of the sliding block.
[0009] Furthermore, the bottom of the sliding block is slidably connected inside the arc-shaped groove, which is used to drive the sliding block to move.
[0010] Furthermore, the outer wall of the sliding block is slidably connected to the inside of the worktable, and the outer wall of the clamping plate is slidably connected to the inside of the worktable.
[0011] Furthermore, the lower surface of the support is fixedly connected to the upper surface of the workbench, which is used to support the support.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a high-efficiency testing fixture for testing photoelectric water meter modules, including a workbench 1, which provides a supporting structure for the entire testing fixture. A central groove on the workbench 1 is used to place the photoelectric water meter module. A cylinder 2 is fixedly connected inside the workbench 1. Through the extension and retraction of its output end, it provides driving force for the horizontal movement of a moving plate 3. The output end of the cylinder 2 is fixedly connected to the moving plate 3, which moves horizontally under the drive of the cylinder 2, thereby driving the movement of four connected L-shaped plates 4. L-shaped plates 4 are fixedly connected to the outer wall of the moving plate 3, connecting the moving plate 3 to branch rods 5 and auxiliary rods 7, converting the horizontal movement of the moving plate 3 into the displacement of the branch rods 5 and auxiliary rods 7. Branch rods 5 are rotatably connected inside the L-shaped plates 4, moving along with the L-shaped plates 4 as they move. By pushing one end of a pressure block 6, the pressure block 6 is actuated, and one end of the branch rod 5... The pressure block 6 is rotatably connected to the end of the L-shaped plate 4. One end of the L-shaped plate 4 is displaced by the push of the branch rod 5, and the other end moves in an arc shape under the action of the auxiliary rod 7 and the rotating rod 9. The auxiliary rod 7 is rotatably connected inside the L-shaped plate 4. By pushing the rotating rod 9 to rotate, the pressure block 6 completes the arc shape. The photoelectric emission plate 8 is fixedly connected to the lower surface of the pressure block 6. Under the action of the pressure block 6, the plate approaches the photoelectric water meter module and emits light. It cooperates with the photoelectric receiver 12 below to complete the detection of the light signal transmission of the photoelectric water meter module. The rotating rod 9 is rotatably connected to the inside of the pressure block 6. It rotates under the push of the auxiliary rod 7, thereby driving the pressure block 6 to make an arc shape. One end of the rotating rod 9 is rotatably connected to the support 10, which is fixed to the upper surface of the workbench 1 to provide a support point for the rotating rod 9. The upper surface of the workbench 1 is fixedly connected to the limit block 11. The inside of the workbench 1 is fixedly connected to the photoelectric receiver 12.
[0025] Specifically, the photoelectric water meter module is first placed in the groove in the middle of the workbench 1, and closely fitted with the photoelectric receiver 12. The cylinder 2 is started, and its output end pushes the moving plate 3 to move horizontally, which drives the four L-shaped plates 4 to move synchronously. When the L-shaped plates 4 move, the branch rod 5 and the auxiliary rod 7 are displaced accordingly. The branch rod 5 pushes one end of the pressure block 6, and the auxiliary rod 7 pushes the rotating rod 9 to rotate, so that the pressure block 6 makes an arc-shaped movement, which drives the photoelectric emission plate 8 to quickly approach the module and cooperate with the photoelectric receiver 12 to complete the optical signal transmission detection.
[0026] Reference Figure 1 , Figure 3 and Figure 4The worktable 1 has a rotating shaft 13 internally connected to it. Driven by an external drive, the worm gear 14 rotates. The worm gear 14 is fixedly connected to the middle of the rotating shaft 13 and rotates under its influence. Through meshing with a worm wheel 15, the rotation of the rotating shaft 13 is transmitted to the worm wheel 15. A rotating plate 16 is also internally connected to the worktable 1. Driven by the worm wheel 15, it rotates. An arc-shaped groove 17 inside the plate 16 drives a sliding block 18 to slide within the worktable 1, thus driving the clamping assembly. A worm wheel 15 is fixedly connected to the outer wall of the rotating plate 16 and meshes with the worm gear 14. Driven by the worm gear 14, the plate rotates, thereby driving the rotating plate 16, which is fixedly connected to it, to rotate. The worm wheel 15 meshes with the worm gear 14. An arc-shaped groove 17 is provided inside the rotating plate 16. A clamping assembly is provided inside the rotating plate 16, including a sliding block 18 and a clamping plate 19. The clamping assembly is driven by its own sliding motion. The plate 19 moves, and the clamping plate 19 moves under the drive of the sliding block 18 to clamp and fix the photoelectric water meter module placed on the workbench 1, preventing the module from shifting during the testing process. The lower surface of the sliding block 18 is slidably connected to the inside of the rotating plate 16, and the outer wall of the clamping plate 19 is fixedly connected to one side of the outer wall of the sliding block 18. The bottom of the sliding block 18 is slidably connected to the inside of the arc-shaped slide groove 17, which is used to drive the sliding block 18 to move. The outer wall of the sliding block 18 is slidably connected to the inside of the workbench 1, and the outer wall of the clamping plate 19 is slidably connected to the inside of the workbench 1. The lower surface of the support 10 is fixedly connected to the upper surface of the workbench 1, and the workbench 1 is used to support the support 10. One end of the auxiliary rod 7 is rotatably connected to the outer wall of the rotating rod 9, and the auxiliary rod 7 is used to assist the rotating rod 9. The photoelectric emission plate 8 is set above the photoelectric receiver 12, and the photoelectric emission plate 8 and the photoelectric receiver 12 are used to test the module.
[0027] Specifically, after the module is placed, the rotating shaft 13 is rotated, which drives the worm gear 14 to rotate. Through meshing with the worm wheel 15, the rotating plate 16 is driven to rotate. The arc-shaped sliding groove 17 in the rotating plate 16 drives the sliding block 18 to slide in the worktable 1. The sliding block 18 drives the clamping plate 19 to clamp and fix the module, preventing the module from shifting during testing and ensuring that the test data is accurate and reliable.
[0028] Working principle: When using the high-efficiency testing fixture for testing photoelectric water meter modules, the photoelectric water meter module is first placed in the groove in the middle of the workbench 1, so that the photoelectric water meter module is in contact with the photoelectric receiver 12. Then, the output end of the cylinder 2 drives the moving plate 3 to move, thereby driving the four L-shaped plates 4 to move. The movement of the L-shaped plates 4 simultaneously drives the branch rod 5 and the auxiliary rod 7 to move. The movement of the branch rod 5 drives one end of the pressure block 6 to move. At the same time, the auxiliary rod 7 pushes the rotating rod 9 to rotate, thereby driving the pressure block 6 to move in an arc, so that the other end of the pressure block 6 carries the photoelectric emission plate 8 towards the photoelectric water meter module, and works with the photoelectric receiver 12 to quickly test the photoelectric water meter module.
[0029] Furthermore, after the photoelectric water meter module is placed, the drive shaft 13 drives the worm gear 14 to rotate. In conjunction with the threaded relationship between the worm gear 14 and the worm wheel 15, the worm wheel 15 drives the rotating plate 16 to rotate with the rotation of the worm gear 14. Then, through the rotation of the rotating plate 16, the internal arc-shaped sliding groove 17 drives the sliding block 18 to slide inside the worktable 1. Thus, the sliding block 18 drives the clamping plate 19 to clamp and fix the photoelectric water meter module, avoiding deviation during testing and other factors that may affect the testing effect.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
