Description

Technical Field

[0001] This utility model belongs to the field of testing fixture technology, specifically relating to a testing fixture for water output uniformity. Background Technology

[0002] In mass manufacturing enterprises, the current goal is to move towards automation. For the various types of products, especially when complex products are injection molded, most companies still use manual labor for the process. How to carry out the operation efficiently and stably has always been a key focus for enterprises.

[0003] The traditional method involves manually inserting a water pipe into the product's water inlet and then visually inspecting whether water is flowing out of the inlet and whether any small holes are not dispensing water. The product has 32 small holes, and each hole must be inspected and confirmed using the above method. Figure 1 , 2 The product shown is typically used in floor cleaning machines. After injection molding, the steam vents need to be inspected to ensure proper steam passage during high-temperature steam disinfection and cleaning. Simultaneously, it's crucial to ensure uniform water output from each steam vent to improve the uniformity of subsequent disinfection and sterilization.

[0004] For the 3C laptop and home appliance industries, product quality requirements are high. Manual inspection carries the risk of product scratches and damage. Therefore, personnel must not only protect the product's appearance to prevent scratches and damage during inspection, but more importantly, manual visual inspection can only check for unobstructed steam vents and cannot guarantee the uniformity of water output from each vent. Consequently, the accuracy of the inspection results cannot be guaranteed. Utility Model Content

[0005] This invention provides a fixture for detecting the uniformity of water output, which solves the problems of low efficiency and inability to detect the uniformity of water output from each steam hole by manual visual inspection.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a fixture for detecting the uniformity of water output, comprising:

[0007] Support frame;

[0008] A contour block, which is fixed to the top of the support frame.

[0009] A contouring groove is formed on the top of the contouring block, and the product to be inspected is placed inside the contouring groove;

[0010] A water collection assembly for collecting liquids used in testing.

[0011] Optimally, it also includes a pressing assembly mounted on top of the contour block, the pressing assembly being used to press the product into the contour groove.

[0012] Ideally, the water collection assembly includes a drain installed inside the contour block and a test tube installed at the bottom of the support frame and connected to the drain, the test tube being provided with graduation lines.

[0013] Optimally, the pressing assembly includes a stop adjustablely mounted on top of the profile block and a pressure plate resiliently mounted on top of the stop, the pressure plate pressing the product into the profile groove.

[0014] Optimally, the water collection assembly further includes a slot formed on the top of the contour block and a through groove formed at the bottom of the slot and extending through the contour block.

[0015] Ideally, the drainer includes a funnel cylinder fitted in the slot and a drain pipe integrally connected to the bottom of the funnel cylinder, the drain pipe passing through the through slot.

[0016] Optimally, the pressing assembly further includes a spring groove formed on the top of the pressure plate, a through hole formed at the bottom of the spring groove and penetrating the pressure plate, a clamping bolt penetrating the pressure plate and fixed in the stop block, and a clamping spring sleeved on the clamping bolt, wherein the clamping spring abuts between the clamping bolt and the spring groove.

[0017] Ideally, the drainer also includes a fixing plate and a retaining plate integrally connected to the top of the drain cylinder and disposed opposite to each other.

[0018] Optimally, the water collection assembly further includes an adjustable plate disposed on the support frame at a height adjustable manner and a through hole passing through the adjustable plate, the through hole being fitted onto the test tube.

[0019] Ideally, the water collection assembly also includes a groove formed at the bottom of the support frame, with the test tube resting in the groove.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] This utility model's water flow uniformity testing fixture positions the product within a positioning jig, then uses a pressing assembly to ensure accurate positioning. The water pump's outlet hose is connected to the product's inlet. The product has four steam holes as a group, with 32 holes divided into eight groups. The steam from the four steam holes converges in a funnel, flowing into a graduated test tube below. Simultaneous outflow allows for visual confirmation of the water level in the graduated test tube, thus confirming the uniformity of the water flow from each hole. The fixture is flexible, compatible, and error-proof; it reduces the number of operators and their workload; after confirmation, the water in the test tube can be poured out, and the entire process can be repeated. The fixture's flexibility, compatibility, and error-proof design improve efficiency, stabilize quality, and achieve lean management goals. Attached Figure Description

[0035] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0036] like Figure 3 , 4 The diagram shown is a structural schematic of the water output uniformity testing fixture of this utility model. This fixture is typically used for... Figure 1 , 2 The product shown undergoes water output testing to ensure the uniformity of water output from the steam vents.

[0037] The base plate 2 is fixed to the top of the foot pads 1 (specifically, there are at least four foot pads 1, which are fixed to the bottom of the base plate 2 by screws, with at least four foot pads 1 located at the four corners of the bottom of the base plate 2 to improve the stability of the base plate 2). The foot pads 1 support the base plate 2, preventing it from rusting due to prolonged direct contact with the machine.

[0038] The groove 3 is located at the top of the base plate 2, on the side of the base plate 2 away from the foot pad 1. The groove 3 is bowl-shaped and fits the bottom structure of the test tube 8 (the number of grooves 3 is the same as the number of test tubes 8). In actual testing, the test tube 8 is placed in the groove 3 of the base plate 2 for positioning and support, preventing the test tube 8 from sliding on the base plate 2.

[0039] There are at least four guide pillars 4, which are fixed to the top of the base plate 2 by screws (specifically, at least four guide pillars 4 are located at the four corners of the base plate 2). The contour block 9 is fixed to the top of the guide pillars 4 by screws, and at least four guide pillars 4 are located at the four corners of the bottom of the contour block 9 (the guide pillars 4 support the contour block 9, improving the stability of the overall structure, while leaving working space between the base plate 2 and the contour block 9 to facilitate the installation and removal of the test tube 8).

[0040] like Figure 7 The diagram shows the structure of the contour block 9, which is fixed to the top of at least four guide posts 4 by screws. A contour groove 10 is formed on the top of the contour block 9, and the contour groove 10 is adapted to the shape of the product to be inspected. During actual inspection, the operator will... Figure 1 , 2The product shown can be placed in the contour groove 10 on top of the contour block 9.

[0041] The pressing component is installed on top of the contour block 9. When the operator places the product to be tested into the contour groove 10, the pressing component presses the product into the contour groove 10. During subsequent water injection testing, this prevents the product from shaking or shifting in the contour groove 10 under the impact of the water flow, which would affect the accuracy of the water output test results.

[0042] Figure 9 This is a schematic diagram of the pressing assembly. Figure 10 The diagram shows a cross-sectional view of the pressing assembly, which includes a stop block 19, an adjusting groove 20, a threaded hole 21, a clamping bolt 22, a clamping spring 23, a spring groove 24, a through hole 25, a pressure plate 26, and a protruding post 27. The threaded hole is located at the top of the profile block 9. The adjusting groove 20 extends vertically through the profile block 9 and is rounded rectangular. The fastening bolt passes through the adjusting groove 20 and is screwed into the threaded hole of the profile block 9, thereby fixing the stop block 19 to the top of the profile block 9. (Because the adjusting groove 20 is rounded rectangular, the position of the stop block 19 can be adjusted horizontally, improving the versatility of the fixture. When the product is placed in the profile groove 10 at the top of the profile block 9, one side of the product abuts against the stop block 11.)

[0043] The threaded hole 21 penetrates vertically through the stop block 19, and the clamping bolt 22 is screwed into the threaded hole 21 of the stop block 19 (specifically, the clamping bolt 22 includes a bolt head and a bolt root, and the outer circumferential surface of the bolt root is provided with external threads, and the bolt root is screwed into the threaded hole 21 of the stop block 19 by screwing).

[0044] A spring groove 24 is formed at the top of the pressure plate 26. The spring groove 24 is used to place the compression spring 23 and to limit the placement of the compression spring 23. A through hole 25 is formed at the bottom of the spring groove 24 and vertically penetrates the pressure plate 26 (e.g., ...). Figure 10 As shown, the inner circumferential surface of the through hole 25 is smooth and has no threaded structure. Moreover, the diameter of the through hole 25 is larger than the diameter of the bolt root, ensuring that the pressure plate 26 can rotate or lift around the bolt root.

[0045] The compression spring 23 is sleeved on the compression bolt 22 (specifically, the compression spring 23 is sleeved on the root of the bolt, and one side of the compression spring 23 abuts against the spring groove 24, and the other side of the compression spring 23 abuts against the bolt head near the root of the bolt).

[0046] During actual testing, the operator first places the product to be tested in the contour groove 10 of the contour block 9, and then lifts the pressure plate 26 upwards, at which point the clamping spring 23 is compressed; the operator rotates the pressure plate 26 until it is above the product, and then releases the pressure plate 26. Under the reset action of the clamping spring 23, the pressure plate 26 presses on the top of the product to be tested, thus completing the pressing of the product.

[0047] The protruding post 27 is integrally connected to the side of the pressure plate 26 away from the clamping bolt 22. To improve structural strength, a reinforcing rib is integrally formed between the protruding post 27 and the pressure plate 26. By setting the protruding post 27, it is convenient for the operator to flip the pressure plate 26 (specifically, the operator holds the protruding post 27 to rotate the pressure plate 26).

[0048] The abutment block 11 is integrally connected to the top of the contour block 9 and is spaced apart. When the product is placed in the contour groove 10, the two sides of the product abut against the abutment block 11 and the stop block 19 respectively, while the pressure plate 26 presses against the top of the product, thereby completing the positioning of the product.

[0049] like Figure 6 As shown, the slot 12 is located at the top of the contour block 9, and the slot 12 is conical (i.e., the diameter of the slot 12 is larger at the top and smaller at the bottom, so that when the auger 14 is inserted into the slot 12, it will be blocked by the slot 12 to prevent the auger 14 from falling out). The through groove 13 is located at the bottom of the slot 12 and vertically penetrates the contour block 9.

[0050] like Figure 8 The diagram shows a schematic of the funnel cylinder 14. The funnel cylinder 14 is funnel-shaped, and the drain pipe 15 is integrally connected to the bottom of the funnel cylinder 14 and communicates with the interior of the funnel cylinder 14. Figure 5 As shown, the drain cylinder 14 is inserted into the slot 12 of the contour block 9, and the drain pipe 15 is inserted into the through groove 13 of the contour block 9 (since both the drain cylinder 14 and the slot 12 are funnel-shaped, the drain cylinder 14 will be stuck in the slot 12).

[0051] The fixing plate 17 is integrally connected to one side of the top of the filter cylinder 14, and the clamping plate 18 is integrally connected to the other side of the top of the filter cylinder 14 and is positioned opposite to the fixing plate 17. After the filter cylinder 14 is inserted into the clamping slot 12, the fixing plate 17 and the clamping plate 18 rest on the top of the contour block 9 (specifically, the fixing plate 17 is located between two adjacent abutment blocks 11), and then the fixing plate 17 is fixed to the contour block 9 by screws, thus completing the fixation of the filter cylinder 14 and preventing the filter cylinder 14 from loosening and shifting its position when collecting and testing liquid.

[0052] By setting opposing fixing plates 17 and clamping plates 18 on the top of the leaking cylinder 14, when the leaking cylinder 14 is placed into the clamping groove 12, the fixing plates 17 and clamping plates 18 support the leaking cylinder 14, preventing the leaking cylinder 14 from being deformed in the clamping groove 12 due to the impact of water flow, which would cause water leakage and affect the test results.

[0053] The steam holes on the product correspond to the funnel 14. During water injection testing, water flows through the steam holes into the funnel 14 and then into the test tube 8 below. The uniformity of water flow from the steam holes can be visually observed through the scale on the test tube 8. The conical shape of the funnel 14 facilitates the flow of water into the test tube 8, preventing water residue in the funnel 14 from causing deviations in the results.

[0054] Test tube 8 is placed in the groove 3 of the base plate 2. One end of the transition tube 16 is installed at the bottom of the drain pipe 15, and the other end extends into the test tube 8. The liquid for water detection (usually water) flows into the funnel 14, and then flows along the funnel 14, drain pipe 15, and transition tube 16 into the test tube 8. The test tube 8 is engraved with scales, which allow you to visually see the amount of water inside each test tube 8, thereby determining which specific holes on the product have uneven water output.

[0055] The transition tube 16 is made of silicone. The flexibility of the silicone tube allows for easy removal of the test tube 8 to drain the water for reuse. The transition tube 16 and the drain tube 15 are connected by an interference fit to prevent water leakage from the gap between them. Simultaneously, the transition tube 16 guides the water flow into the test tube 8, preventing splashing and ensuring accurate test results.

[0056] During actual testing, one end of a water pipe is connected to the product's water inlet. Tap water is injected into the pipe, flowing through the steam hole into the product's internal channels, then into the infuser 14, and finally through the infuser 14, drain pipe 15, and transition pipe 16 into test tube 8. Test tube 8 is graduated, allowing for a direct visual observation of the water volume in each tube, thus identifying which specific holes on the product have uneven water flow (e.g.,...). Figure 2 The diagram shows the internal flow channels of the product. The arrows indicate the direction of water flow. As can be seen from the diagram, the internal flow channels of the product are all symmetrical structures, so the water reaches each steam hole in the same time.

[0057] like Figure 2 As shown, the product has a total of 32 steam holes, with four steam holes forming a group, for a total of eight groups of steam holes, which correspond to the eight funnels 14 and eight test tubes 8 on the fixture.

[0058] The adjusting plate 5 can be adjusted along the height of the guide post 4, thereby providing horizontal support for the test tube 8 and preventing the test tube 8 from tipping over (because the groove 3 at the top of the base plate 2 only provides auxiliary support for the test tube 8 to prevent the test tube 8 from slipping on the base plate 2, and cannot guarantee that the test tube 8 is in an upright position).

[0059] The adjusting plate 5 has guide holes 7 that mate with the guide post 4 to ensure the stability of the adjusting plate 5 during lifting. Figure 11 As shown, the cylinder fixing plate is fixed to both sides of the contour block 9 by welding, and the cylinder body is fixed to the bottom of the cylinder fixing plate by screws. The piston rod of the cylinder is connected to the adjusting plate 5. The adjusting plate 5 is raised and lowered by the cylinder, thereby achieving the positioning of the test tube 8.

[0060] The through hole 6 passes through the adjusting plate 5, and the test tube 8 passes through the through hole 6 and is placed in the groove 3 of the base plate 2. The diameter of the through hole 6 is larger than the outer diameter of the test tube 8, so that the operator can easily remove the test tube 8.

[0061] During actual testing, test tube 8 is placed in the groove 3 of the base plate 2. The cylinder drives the adjusting plate 5 to rise to the middle position of test tube 8. Test tube 8 abuts against the inner side wall of the through hole 6 of the adjusting plate 5 to prevent test tube 8 from tipping over.

[0062] During water injection testing, one end of the water pipe is connected to the product's water inlet, and tap water is injected into the pipe. The tap water flows out from the steam hole along the internal flow channel of the product, then falls into the funnel 14, and finally flows through the funnel 14, drain pipe 15, and transition pipe 16 into the test tube 8. The test tube 8 is marked with graduations, which allow for a direct visual observation of the water volume inside each test tube 8, thus identifying which specific holes on the product have uneven water output.

[0063] When it is necessary to remove test tube 8, the cylinder drives the adjusting plate 5 to descend until the adjusting plate 5 is close to the bottom of test tube 8 (the adjusting plate 5 is not in contact with the base plate 2). At this time, test tube 8 is still against the inner side wall of the through hole 6 of adjusting plate 5, so test tube 8 will not tip over. The operator can pull test tube 8 upward and pour out the water in test tube 8.

[0064] This utility model's water flow uniformity testing fixture positions the product within a positioning jig, then uses a pressing assembly to ensure accurate positioning. The water pump's outlet hose is connected to the product's inlet. The product has four steam holes as a group, with 32 holes divided into eight groups. The steam from the four steam holes converges in a funnel, flowing into a graduated test tube below. Simultaneous outflow allows for visual confirmation of the water level in the graduated test tube, thus confirming the uniformity of the water flow from each hole. The fixture is flexible, compatible, and error-proof; it reduces the number of operators and their workload; after confirmation, the water in the test tube can be poured out, and the entire process can be repeated. The fixture's flexibility, compatibility, and error-proof design improve efficiency, stabilize quality, and achieve lean management goals.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
