Description

Technical Field

[0001] This utility model relates to the field of dry bottle testing technology, and in particular to a four-station dry bottle water testing station. Background Technology

[0002] The automotive air conditioning refrigerant receiver-drier is an important component installed between the evaporator and condenser of the automotive air conditioning system. Its main function is to separate gaseous and liquid refrigerant, store excess liquid refrigerant, and remove excess moisture and impurities from the refrigeration system. The manufacturing process of the receiver-drier is demanding, its structure is complex, and it is used under harsh conditions, making it prone to failure. The sealing performance of the receiver-drier directly determines its performance. If the receiver-drier is not well sealed and refrigerant leaks, it will directly cause the automotive air conditioning system to fail. Therefore, the receiver-drier needs to undergo airtightness testing before leaving the factory.

[0003] Currently, Chinese utility model patent CN206470027U discloses a device for testing the airtightness of a liquid storage drying bottle, including a frame, a water tank that can be raised and lowered on the frame, a drying bottle fixing frame fixedly installed in the water tank, multiple through holes at the bottom of the drying bottle fixing frame, multiple sets of drying bottle fixing mechanisms installed inside the drying bottle fixing frame, each drying bottle fixing mechanism including a cylinder, a push rod at the output shaft end of the cylinder, the cylinder fixedly installed on one side of the drying bottle fixing frame, and an air inlet fixedly installed on the other side of the drying bottle fixing frame corresponding to the push rod, the air inlet being fixed to the other side of the drying bottle fixing frame by a fixing block.

[0004] Existing utility models use a drying bottle fixing mechanism to fix the drying bottle on a drying bottle holder, and the air inlet is sealed to the air inlet of the drying bottle. The drying bottle is submerged in the medium water by a rising water tank, allowing the air tightness of the drying bottle to be observed. However, this method can only test the sealing performance of the drying bottle in a static state, while in actual use scenarios the drying bottle is in constant motion, lacking test accuracy and requiring improvement.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a four-station drying bottle water testing station, including a base and a water tank fixedly connected to the base; at least two sets of lifting seats are movably connected to the base in the vertical direction based on a guide lifting assembly, and a rotating disk is symmetrically rotatably connected to both ends of the lifting seats; a fixing assembly for fixing the drying bottle is fixedly connected to the rotating disk; a rotation drive assembly for driving the rotating disk to rotate synchronously is fixedly connected to the lifting seat; and an inflation assembly for injecting high-pressure gas into the drying bottle is also fixedly connected to the base.

[0008] The present invention is further configured such that: the rotary drive assembly includes a drive motor fixedly connected to the lifting seat along the horizontal direction and a first drive pulley fixedly connected to the rotating shaft of the drive motor; a second drive pulley is fixedly connected to the rotating disk coaxially; and the first drive pulley and the second drive pulley are driven by a transmission belt.

[0009] The present invention is further configured such that: the fixing component includes a U-shaped fixing seat fixedly connected to the rotating disk and an abutting fixing rod slidably connected to one end of the U-shaped fixing seat for abutting the bottom of the drying bottle; a locking lever is rotatably connected to the U-shaped fixing seat for driving the abutting fixing rod to slide; a positioning fixing hole for positioning the mouth of the drying bottle is opened at the end of the U-shaped fixing seat away from the locking lever; and a gas discharge hole communicating with the positioning fixing hole for high-pressure gas to be discharged is also opened on the U-shaped fixing seat.

[0010] The present invention is further configured such that: the inflation assembly includes a high-pressure gas source fixedly connected to the base and a pressure regulating valve connected to the high-pressure gas source; the pressure regulating valve is externally connected to a gas distributor; the gas distributor is externally connected to multiple inflation tubes for inflation of the drying bottle; and the inflation tubes are equipped with solenoid valves for controlling the gas flow.

[0012] The present invention is further configured such that: a drain pipe is provided at the bottom of the water tank, and a switch valve is provided on the drain pipe.

[0014] 1. By symmetrically rotating a rotating disk at both ends of the lifting base and installing a fixed component on the rotating disk, and simultaneously installing a rotation drive component on the lifting base, the rotation drive component drives the rotating disk and the desiccant bottle fixed on the rotating disk to rotate, thereby testing the sealing performance of the desiccant bottle in motion, which improves the accuracy of the sealing performance test. At the same time, before testing the desiccant bottle, high-pressure air is injected into the desiccant bottle through an inflation component. On the one hand, this can avoid the problem of misjudging the desiccant bottle's sealing performance due to poor sealing between the inflation structure and the desiccant bottle. On the other hand, if the desiccant bottle leaks air, dense and continuous bubbles will be generated in the water, avoiding the influence of bubbles generated by the desiccant bottle being stirred in the water.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] refer to Figures 1 to 4A four-station desiccant bottle water testing station includes a base 1 and a water tank 2 fixedly connected to the base 1. A drain pipe 21 is provided at the bottom of the water tank 2, and a switch valve 22 is provided on the drain pipe 21. The switch valve 22 allows for periodic replacement of the water in the water tank 2. At least two sets of lifting seats 4 are movably connected to the base 1 along the vertical direction based on a guide lifting assembly 3. Rotary disks 5 are symmetrically rotatably connected to both ends of the lifting seats 4. Fixing assemblies 6 for fixing the desiccant bottles are fixedly connected to the rotating disks 5. A rotation drive assembly 7 for synchronously rotating the rotating disks 5 is fixedly connected to the lifting seats 4. The base 1... An inflation assembly 8 is also fixedly connected to the desiccant bottle for injecting high-pressure gas. The rotation drive assembly 7 drives the rotating disk 5 and the desiccant bottle fixed on the rotating disk 5 to rotate, thereby testing the sealing performance of the desiccant bottle in motion, improving the accuracy of the sealing test. Simultaneously, before testing the desiccant bottle, high-pressure air is injected into the desiccant bottle via the inflation assembly 8. This avoids misjudging the desiccant bottle's sealing performance due to poor sealing between the inflation structure and the desiccant bottle. Furthermore, if the desiccant bottle leaks, dense and continuous bubbles will be generated in the water, avoiding the influence of bubbles generated by the desiccant bottle's agitation in the water. In this embodiment, two sets of lifting seats 4 are provided, each with two rotating disks 5, forming four testing stations. The two lifting seats 4 rise and fall alternately. When the rotation drive assembly 7 on one lifting seat 4 operates to test the desiccant bottle, the other lifting seat 4 simultaneously performs the desiccant bottle loading and unloading process, thereby reducing wasted time during the testing process and improving testing efficiency.

[0023] refer to Figure 1 and Figure 4 Specifically, the guide lifting assembly 3 includes a guide rod 31 fixedly connected to the lifting seat 4 in the vertical direction and a guide sleeve 32 fixedly connected to the base 1. A lifting cylinder 33 that drives the lifting seat 4 to lift is fixedly connected to the base 1 in the vertical direction. The lifting seat 4 is stabilized through the assembly of the guide rod 31 and the guide sleeve 32.

[0024] refer to Figures 1 to 2 Specifically, the rotary drive assembly 7 includes a drive motor 71 fixedly connected to the lifting seat 4 along the horizontal direction and a first drive pulley 72 fixedly connected to the rotating shaft of the drive motor 71. A second drive pulley 73 is fixedly connected to the rotating disk 5 on the same axis. The first drive pulley 72 and the second drive pulley 73 are driven by a transmission belt 74. The drive motor 71 drives the first drive pulley 72 to rotate, and the first drive pulley 72 drives the two second drive pulleys 73 to rotate synchronously through the transmission belt 74, thereby driving the rotating disk 5 and the drying bottle to rotate synchronously.

[0025] refer to Figures 2 to 3Specifically, the fixing component 6 includes a U-shaped fixing seat 61 fixedly connected to the rotating disk 5 and an abutting fixing rod 62 slidably connected to one end of the U-shaped fixing seat 61 for abutting the bottom of the desiccant bottle. A locking lever 63 is rotatably connected to the U-shaped fixing seat 61 for sliding the abutting fixing rod 62. The locking lever 63 is similar in principle to the quick-clamp structure on the market. By rotating the locking lever 63, the abutting fixing rod 62 is slidably moved, thereby releasing or clamping the desiccant bottle. A positioning fixing hole 64 for positioning the mouth of the desiccant bottle is provided at the end of the U-shaped fixing seat 61 away from the locking lever 63. A gas discharge hole 65 is also provided on the U-shaped fixing seat 61, which is connected to the positioning fixing hole 64 for high-pressure gas to be discharged. When the mouth of the desiccant bottle leaks gas, it is discharged directly through the gas discharge hole 65.

[0026] refer to Figure 1 and Figure 4 Specifically, the inflation assembly 8 includes a high-pressure gas source 81 fixedly connected to the base 1 and a pressure regulating valve 82 connected to the high-pressure gas source 81. A gas distributor 83 is connected to the pressure regulating valve 82 to achieve gas diversion. Multiple inflation tubes 84 for inflation of the dry bottle are connected to the gas distributor 83. The inflation tubes 84 are equipped with solenoid valves 85 for controlling the gas flow. When the mouth of the dry bottle is aligned with the inflation tube 84, the solenoid valve 85 is opened to inject high-pressure gas into the dry bottle. A digital pressure gauge 86 for detecting the gas source pressure is also provided on the base 1 to monitor the pressure of the high-pressure gas source 81 in real time and avoid insufficient pressure of the high-pressure gas source 81 affecting the high-pressure gas in the dry bottle.

[0027] Brief description of the usage process: Before testing the desiccant bottle, high-pressure air is injected into the desiccant bottle through the inflation component 8 and the desiccant bottle is fixed on the fixing component 6. Then, the lifting component drives the lifting seat 4 and the fixing component 6 to descend, so that the desiccant bottle is immersed in the water tank 2. Finally, the rotation drive component 7 drives the rotating disk 5 and the desiccant bottle fixed on the rotating disk 5 to rotate, thereby testing the sealing performance of the desiccant bottle in motion.
