This application proposes a special airtight detection device for water tanks, which relates to the field of airtightness detection machinery. It includes a frame and a lifting cylinder. The frame is placed on the ground, and a water storage tank is arranged inside the frame. A lifting frame is arranged above the water storage tank. Two lifting cylinders are symmetrically arranged on the frame. A positioning frame and a sealing cylinder are arranged on the lifting frame. Several test water tanks are placed on the positioning frame, and sealing holes are formed on the test water tanks. The deficiencies of this technical solution are as follows: 1. The specifications and sizes of the test workpieces are fixed, resulting in poor applicability; 2. Manual multi-step operations are required for loading and unloading, resulting in reduced efficiency.

[0004] In summary, the existing water tank testing devices have the deficiencies of poor applicability and low efficiency. Summary of the Invention

[0005] The present invention is to overcome the deficiencies of poor applicability and low efficiency of the water tank testing device in the prior art, and provides a water tank immersion test workbench that improves multi-applicability and work efficiency.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A water tank immersion test workbench, comprising a frame, a workbench is installed on the frame, and the workbench is connected to a test water tank; a feeding and discharging assembly, the frame is connected to a support frame, the support frame is movably connected to a finishing pressing plate, several feeding and discharging assemblies are arranged above the test water tank. The feeding and discharging assembly includes a workpiece positioning seat and a feeding structure. The station positioning seat is movably connected to the support frame through the finishing pressing plate, and the feeding structure is movably connected to the support frame; a clamping assembly, the frame is movably connected to a lifting plate, several clamping assemblies are arranged above the test water tank. The clamping assembly includes a vertical plate, a fixed clamping rod and a movable clamping rod. The vertical plate is movably connected to the lifting plate, the fixed clamping rod is connected to the vertical plate, the movable clamping rod is movably connected to the vertical plate, and a discharging structure is movably connected to the vertical plate; The pressure measuring structure is provided with several and is connected to the lifting plate, and the vertical plate is movably connected to the pressure measuring structure; The auxiliary structure, the test water tank is connected with a liquid level sensor. The auxiliary structure includes a water delivery pipe and a lighting lamp. The water delivery pipe is connected to the test water tank, and the lighting lamp is connected to the frame and placed on one side of the test water tank.

[0007] The workbench is connected to the frame to support and place the test water tank. The feeding and discharging assembly is used to load the workpiece into the clamping assembly for fixing, and then the clamping assembly releases and unloads the workpiece to the feeding and discharging assembly for discharging. Multiple feeding and discharging assemblies correspond to multiple clamping assemblies to achieve multi-station batch operation; among them, the station positioning seat in the feeding and discharging assembly is used to position and arrange the placement of the workpiece to assist in quickly and correctly placing the workpiece, and the feeding structure automatically feeds and docks the placed workpiece to the clamping assembly. The sorting pressing plate realizes the height sorting of the placed workpiece by moving on the support frame of the frame, so as to ensure the correct docking position between the workpiece and the clamping assembly before the feeding structure operates. This includes different specifications (capacity depth) due to the change in the capacity of the water tank, so as to ensure multi-specification sorting operations for multiple stations, and correct feeding and fixing can be achieved without manual adjustment; each component is connected to the movable lifting plate, and enters or leaves the test water tank through the movement of the lifting plate. Then, the workpiece on the clamping assembly is immersed in the test water tank, and the airtightness test is observed through the generation of bubbles. Among them, the moving clamping rod in the clamping assembly flexibly clamps and fixes the workpiece by cooperating with the fixed clamping rod. The vertical plate is connected to the lifting plate to ensure that the workpiece is clamped by the fixed clamping rod and the moving clamping rod and enters and exits the test water tank. The discharging structure discharges the workpiece at the reset height after the test and returns the workpiece to the workpiece positioning seat, enabling automatic batch discharging of the workpiece; the pressure measuring structure is connected to the lifting plate to measure the pressure on the vertical plate, and monitors the pressure on the vertical plate after the workpiece is immersed in water. Compared with traditional manual detection or simple equipment detection, it can more accurately judge the sealing performance of the water tank and the ability to withstand water pressure, greatly improving the accuracy of the detection results; the liquid level sensor is installed in the test water tank to monitor the liquid level height of the water inlet and drainage of the test water tank by the water delivery pipe, so as to ensure that the water level is sufficient for the test water level and prevent water from overflowing the test water tank due to too high water level, thus realizing automatic monitoring. At the same time, the operation of the conveying pipe reduces the waiting time and facilitates quick next-round testing, further improving the overall work efficiency; the test water tank is made of visible materials to facilitate the observation of bubbles, and the lighting lamp on the frame illuminates the test water tank, further facilitating the observation of bubble details and improving the reliability of the detection results. Precise detection avoids the situation of repeated detection due to misjudgment or unqualified products flowing into the market, reducing potential economic losses. It achieves the effects of realizing efficient airtightness testing, adapting to synchronous testing of different specifications of workpieces to improve the practicality of testing, realizing batch loading and unloading for quick testing, improving testing accuracy, enhancing the degree of automation, and saving manual effort.

The sorting pressing plate is connected to move up and down on the machine frame through the first telescopic mechanism on the support frame, so that the sorting pressing plate presses the workpiece on the base at a certain height, making the top surface height of the workpiece consistent, and thus keeping the clamping point heights of workpieces of the same specification consistent and the clamping point heights of workpieces of different specifications similar. The first elastic mechanism receives the reaction force of the workpiece against the sorting pressing plate under the pressure of the sorting pressing plate, enabling the workpiece to automatically cooperate with the sorting pressing plate to adjust the height to the height set by the sorting pressing plate. Therefore, the upper ends of workpieces of different specifications can all maintain an accurate synchronous height. The support rod slides on the fixed block under the pressure of the base, keeping the base moving linearly up and down and preventing it from tilting and being unable to dock with the clamping component.

The vertical plate 9 is connected with a wing plate 53. The wing plate 53 is provided with a guide rod four 54 and an elastic mechanism five 55. The guide rod four 54 is inserted into the lifting plate 8. One end of the guide rod four 54 is connected with the wing plate 53, and the other end of the guide rod four 54 is connected with a limiting plate five 56. The elastic mechanism five 55 is connected with the guide rod four 54. One end of the elastic mechanism five 55 is connected with the wing plate 53, and the other end of the elastic mechanism five 55 is connected with the lifting plate 8. The pressure measurement structure 12 includes a pressure sensor 57 and a bracket 58. The pressure sensor 57 is connected with the bracket 58. The bracket 58 is connected with the lifting plate 8. The vertical plate 9 is arranged opposite to the pressure sensor 57.

[0034] As Figures 1 - 9 As shown in Figures 1 - 9 , a stable seat 59, a rotating rod 60, a fixed column 61, and an elastic mechanism six 62 are connected to the base 17. One end of the guide bar 26 is inserted into the rotating rod 60. The rotating rod 60 is connected with the stable seat 59. The other end of the guide bar 26 is connected with the elastic mechanism six 62. The elastic mechanism six 62 is connected with the fixed column 61, so that the guide bar 26 can stabilize the workpiece. At the same time, the structural shape of the guide bar 26 is triangular prism-shaped (as shown in Figure 6 ), so that the workpiece can be placed into the placement groove 23 along the inclined plane to improve the placement smoothness, and further ensure the safety and reliability of the feeding and discharging of the workpiece during the test, and avoid the workpiece falling due to instability. Figure 6

[0035] A linear guide rail mechanism 63 is connected to the workbench 2. The linear guide rail mechanism 63 is an existing mechanism of a linear movement driving mechanism. The support frame 5 is connected with the linear guide rail mechanism 63. Then, the support frame 5 reciprocates under the drive of the linear guide rail mechanism 63, thereby adjusting the distance between the workpiece and the clamping assembly 7, making it easier for the workpiece to be docked. At the same time, it increases the manual operation space for feeding and discharging on the base 17 and improves the placement efficiency.

[0036] ​The prior art of elastic mechanism 1 to elastic mechanism 6 are all spring structures, the prior art of telescopic mechanism 1 to telescopic mechanism 4 are all cylinder structures, and buffer cushion 1 to buffer cushion 4 are all made of soft rubber materials. The water delivery pipe 14 includes a drain pipe 64 and a water inlet pipe 65. Both the drain pipe 64 and the water inlet pipe 64 are connected to a water pump structure (not shown in the figure) to realize the water discharging and water adding operations of the test water tank 3. Among them, the liquid level sensor 13 is a prior art pressure sensor for measuring the liquid level, and is installed in the test water tank 3 to monitor the liquid level.

[0037] The pressure sensor 57 is a prior art device. The vertical plate 9 is suspended by the support of the guide rod 4 and the limit plate 56 for the wing plate 53, and then the clamped workpiece is suspended and clamped. The end of the vertical plate 9 passes through the movable opening 52 and abuts against the pressure sensitive element of the pressure sensor 57, so that when the workpiece is subjected to the buoyancy of water, it applies a force to compress the elastic mechanism 5, and then the pressure sensitive element of the pressure sensor 57 is synchronously forced to measure the change of the pressure value.

[0038] The frame 1 is made of aluminum profile materials. A bottom plate is installed on the frame 1 and placed under the workbench 2 to prevent water from entering. The bottom plate is connected to a control system (not shown in the figure) and a power switch base 66. The support cross plate 32 is connected to a manual switch valve 67. In this embodiment, taking three test stations as an example, three manual switch valves 67 are provided and are respectively electrically connected to the three telescopic mechanisms 4, so as to manually select and control the switch for the workpiece clamping operation. The telescopic mechanism 1, the telescopic mechanism 2, the telescopic mechanism 3, the telescopic mechanism 4, the lighting lamp 15, the hydraulic sensor 13, the pressure sensor 57 and the linear guide mechanism 63 are all electrically connected to the control system. The control system is a prior art electrical circuit control device capable of receiving signals and circuit transmission to control each device structure through the control system. The power switch base 66 is electrically connected to the control system to control the switching on and off of the circuit. Among them, the signal processing units of the hydraulic sensor 13 and the pressure sensor 57 transmit signals to the control system to realize the monitoring of the water level and pressure changes.

[0039] The maximum compression amount of the elastic mechanism 3 is greater than the clamping distance between the fixed clamping rod 10 and the movable clamping rod 11 of the smallest specification workpiece to adapt to applying a stable clamping force to workpieces of different specifications.

[0040] The outer end of the guide bar 26 is connected with a sliding arc rod 69 (as Figure 5 shown), so that when the workpiece re-enters the base 17, it can push open the guide bar 26 along the sliding arc rod 69 and be more smooth.

[0041] The lower end of the frame 1 is installed with universal wheels 68 to facilitate the movement, use and maintenance of the workbench 2.

[0042] The test water tank 3 is made of acrylic material, so as to facilitate the quick observation of bubbles through the structure of the transparent material.

[0043] When the workbench is tested (including the workpiece water tank 70 to be tested, as Figure 7 shown, the groove on the outer side of the water tank 70 is set as the lower clamping point of the fixed clamping rod 10 on the water tank 70, and the end face is the upper clamping point of the moving clamping rod 11): The water pump connected through the water inlet pipe 65 in the test water tank 3 stores water, and the liquid level sensor 13 monitors the water level. After the water is stored to the specified height, the water inlet stops. Place the water tank 70 in the placement groove 23 of the base 17, where the guide strip 26 clamps the water tank 70 and makes the upper and lower clamping points of the water tank 70 correspond to the upper and lower positioning wire grooves 24, and start the test through the control system. The power switch base 66 turns on the power, and the telescopic structure one 16 is started to drive the finishing pressing plate 6 to press down, so that the finishing pressing plate 6 abuts on the upper end face (partially) of the water tank 70 and drives the water tank 70 to move down until the height of the lower clamping point of the water tank 70 is the same as the horizontal height of the fixed clamping rod 10 (considering the depth of the placement groove 23). Start the linear guide rail mechanism 63 to make the support frame 5 drive the feeding and discharging assembly 4 close to the clamping assembly 7 until the fixed clamping rod 10 (buffer soft pad two 39) stops moving at the opening of the lower clamping point of the water tank 70. Start the telescopic mechanism two 27 to make the limiting plate two 30 push the feeding push rod 28 to move on the side plate 18, and then the buffer soft pad one 31 pushes the water tank 70 forward, and the lower clamping point is inserted into the fixed clamping rod 10 (buffer soft pad two 39). The water tank 70 squeezes open the guide strip 26 and moves along the guide inclined plane 25 to dock with the fixed clamping rod 10. By starting the telescopic mechanism four 45, the clamping rod 46 compresses the moving clamping rod 11, and then the clamping jaw 40 (buffer soft pad three 41) and the fixed clamping rod 10 cooperate up and down to clamp the water tank 70 (at this time, the blanking push rod 48 includes the buffer soft pad four 51 and is compressed by the elastic mechanism four 49 due to the pushing of the workpiece entering). Retract the base 17 through the linear guide rail mechanism 63, and the telescopic mechanism four 45 compresses the water tank 70 to complete the feeding.

[0044] Turn on the lighting lamp 15, start the telescopic mechanism three 33, so that the linkage rod 34 drives the lifting plate 8 to descend, driving the water tank 70 to descend. During the descent, the air in the inner cavity is compressed by the liquid to generate an upward buoyancy force until the water tank 70 is completely immersed in the test water tank 3. At this time, observe the generation of bubbles on the surface of the water tank 70 to observe the inner cavity tightness of the water tank 70, as well as the force exerted by the buoyancy on the vertical plate 9 through the water tank 70. The tightness and pressure resistance of the water tank 70 are observed by observing the numerical change of the pressure sensor 57 (in the case of poor tightness, bubbles overflow from the leakage holes of the water tank 70, and the more bubbles, the smaller the buoyancy value and the smaller the pressure value). Through the above, qualified and unqualified products of the water tank 70 are measured.

[0045] After the test is completed, raise the height of the lifting plate 8 so that the lowest end of the water tank 70 is higher than the height of the base 17 at this time. Move the support frame 5 again so that the base 17 is docked with the lower end of the water tank 70. Loosen the moving clamping rod 11 through the fourth telescopic mechanism 45. The feeding push rod 48 is pushed back onto the base 17 and away from the fixed clamping rod 10 by the elastic force of the reset of the compressed spring mechanism four 49. Then, move the support frame 5 to move the workpiece away and quickly remove the tested water tank 70. Place the water tank 70 according to whether it passes or fails the sealing test results to complete the feeding. Then, the above operations can be carried out again for the next batch of tests.
