Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipeline quality testing technology, and in particular to an automotive air conditioning pipeline quality testing device. Background Technology

[0002] Air conditioning piping is a network of pipes connecting various components of an air conditioning system (such as the compressor, condenser, and evaporator) and used to transport refrigerant. Its quality directly affects the cooling effect, energy efficiency, and safety of the air conditioner. The necessity of quality testing includes: 1) ensuring airtightness to prevent refrigerant leakage that could lead to performance degradation or environmental pollution; 2) verifying the pressure and corrosion resistance of materials to avoid malfunctions caused by cracking or aging; 3) inspecting welding and assembly processes to reduce blockages or refrigerant flow resistance; and 4) complying with industry standards (such as ISO 5149) to ensure user safety and product reliability. Inferior piping may lead to increased energy consumption, shortened lifespan, and even the risk of refrigerant combustion and explosion.

[0003] Existing air conditioning pipeline inspection methods have significant drawbacks: they mainly rely on manual visual inspection or simple tools for shape matching, which can easily lead to missed detection of minor deformations or dimensional deviations due to visual fatigue; at the same time, the sealing test often uses the traditional method of soaking in water to observe bubbles, which is not only inefficient and requires subsequent drying, but also makes it difficult to accurately locate micro-leak points and quantify the degree of leakage; in addition, the separation of shape inspection and airtightness inspection processes increases the complexity of operation and time costs. Utility Model Content

[0004] The purpose of this invention is to provide a quality inspection device for automotive air conditioning pipes, which solves the problem that the inspection of air conditioning pipes in the prior art mainly relies on manual visual inspection or simple tools for shape matching judgment, and is prone to omission of small deformations or size deviations due to visual fatigue.

[0005] To achieve the above objectives, an automotive air conditioning pipeline quality testing device is provided, comprising a base, a bracket three fixedly connected to the upper left end of the base, a bracket one fixedly connected to the upper middle part of the base, a bracket two fixedly connected to the upper right end of the base, and a pipeline testing fixture fixedly connected to the top of the bracket two and the bracket one.

[0006] The pipeline inspection fixture has a pipeline body inside, and the bracket three has a sealing component two installed at the open end of one side of the pipeline body.

[0007] According to the aforementioned automotive air conditioning pipeline quality testing device, a sealing component is installed on the other side of the pipeline body corresponding to the bracket two, and a pressure sensor is installed inside the sealing component one.

[0008] According to the aforementioned automotive air conditioning pipeline quality testing device, a gas conveying device is installed at the rear end of the bracket three, and a connecting pipe one is provided through the top of the gas conveying device.

[0009] According to the aforementioned automotive air conditioning pipeline quality testing device, the other end of the connecting pipe is connected to the sealing component.

[0010] According to the aforementioned automotive air conditioning pipeline quality testing device, a connecting pipe 2 is provided at the other end of the gas delivery equipment, and the other end of the connecting pipe 2 is provided inside the sealing component 1.

[0011] According to the aforementioned automotive air conditioning pipeline quality testing device, an alarm module is installed on the top of the bracket three, and the alarm module is also connected to the gas delivery equipment via a connecting pipe.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. This device achieves efficient detection through a dual collaborative structure of structural matching for initial screening and dynamic air pressure monitoring. By integrating standard pipeline configurations into the detection fixture, physical matching of shape and size is completed simultaneously during clamping, instantly intercepting products with structural defects. Secondly, a closed-loop air pressure monitoring structure is adopted, which creates a sealed environment through sealing components and uses embedded pressure sensors to dynamically track pressure decay. Once the value is abnormal, the alarm module is triggered to actively sort out defective products, significantly improving detection coverage and automation level.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides an automotive air conditioning pipeline quality inspection device, including a base 1, a bracket 3 8 fixedly connected to the upper left end of the base 1, a bracket 1 2 fixedly connected to the upper middle part of the base 1, and a bracket 2 3 fixedly connected to the upper right end of the base 1. A pipeline inspection fixture 6 is fixedly connected to the top of the bracket 2 3 and the bracket 1 2. By setting the bracket 1 2 and the bracket 2 3, the entire pipeline inspection fixture 6 can be stably supported. The pipeline inspection fixture 6 is designed according to the path of the pipeline body 9. When clamping it, if the pipeline body 9 does not match, it can be determined whether the pipeline is qualified, thus realizing the initial inspection of the pipeline body 9.

[0024] The pipeline inspection fixture 6 has a pipeline body 9 inside. The bracket 3 8 has a sealing component 2 10 installed at one open end of the pipeline body 9, and the bracket 2 2 has a sealing component 1 5 installed at the other open end of the pipeline body 9. The sealing component 1 5 has a pressure sensor 4 installed inside. By setting the sealing component 1 5 and the sealing component 2 10, both ends of the pipeline can be sealed. When the gas is pressurized, gas leakage from the openings at both ends can be prevented. The pressure sensor 4 installed inside the sealing component 1 5 can monitor the internal pressure of the pipeline body 9 in real time.

[0025] A gas delivery device 12 is installed at the rear end of the support 3 8. A connecting pipe 7 is installed through the top of the gas delivery device 12. The other end of the connecting pipe 7 is connected to the sealing component 5. A connecting pipe 2 11 is installed through the other end of the gas delivery device 12. The other end of the connecting pipe 2 11 is installed inside the sealing component 5. By setting the gas delivery device 12, it can be connected to an external air pump, thereby delivering gas to the inside of the pipeline body 9. Stable delivery can be achieved with the help of the connecting pipe.

[0026] An alarm module 13 is installed on the top of bracket 38. The alarm module 13 is also connected to the gas delivery equipment 12 via a connecting pipe. The pressure sensor 4 is electrically connected to the alarm module 13. The value of the pressure sensor 4 is set. When the value of the pressure sensor 4 drops, the alarm module 13 will be triggered, thereby reminding the surrounding workers to take out the pipeline body 9 and place it in the defective products for classification.

[0027] Working principle: During use, the operator places the pipe body 9 on the pipe inspection fixture 6 on top of bracket 1 2 and bracket 2 2. The pipe inspection fixture 6 is designed according to the specified size and shape of the standard pipe. It can not only stably clamp and inspect the pipe body 9, but also check whether the size and shape of the pipe body 9 conforms to its production standards based on the position of the fixture. After clamping the pipe body 9, its two ends are aligned with two sealing parts. The sealing parts can seal both ends of the pipe body 9. At this time, the gas delivery device 12 is connected to the external air pump to pressurize the gas inside the pipe body 9. After the pressure reaches a certain level, the air pump stops working. At this time, the air pressure inside the pipe body 9 is maintained within the specified pressure index. After a period of time, if the pressure value in the pipe body 9 drops, the pressure sensor 4 can detect the pressure change, thereby triggering the alarm 13 to sound an alarm, reminding the surrounding staff to pick out defective products and improve the detection effect of the entire detection device.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
