Description

Technical Field

[0002] The automotive air conditioning system encompasses heating, cooling, air purification, and control systems. The cooling system includes a refrigerant (evaporator), compressor, condenser, expansion valve, receiver-drier, and high and low pressure refrigerant circulation lines connecting them. The main function of the cooling system is to regulate and control the temperature and humidity of the air entering the vehicle's interior. This air can be either the original air inside the vehicle or air entering from outside. Specifically, the refrigerant circulating within the cooling system exchanges heat with the air passing through the vehicle's interior via the refrigerant (evaporator) and condenser through heat absorption and condensation (heat dissipation), thereby creating a comfortable driving and riding environment for the driver and passengers.

[0003] The flexible high-pressure pipe assembly for heavy-duty truck air conditioning is a key component connecting the compressor and condenser in the heavy-duty truck air conditioning refrigeration system. Due to the different installation positions of components such as the evaporator, condenser, expansion valve, and compressor in the automotive air conditioning refrigeration system, and the limited space, the refrigerant circulation pipeline connecting these components is extremely tortuous and complex. Therefore, the designed pipeline route also exhibits a winding and varied characteristic. In the actual manufacturing process, if conventional measuring tools are used to inspect its dimensions, many difficulties will be encountered. Not only is it difficult to ensure product consistency and dimensional accuracy, but it is also extremely time-consuming, thus affecting the production schedule. Utility Model Content

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 4This utility model provides a dimensional gauge for a compressor-condenser refrigerant circulation pipeline A, comprising a base plate 1, a compressor side pressure column 2 mounted on the upper side of the base plate 1, the compressor side pressure column 2 located on the left side of the base plate 1, and a condenser side pressure guide plate 3 mounted on the side of the base plate 1 away from the compressor side pressure column 2, the condenser side pressure guide plate 3 located on the right side of the base plate 1, and a dimensional detection assembly mounted between the compressor side pressure column 2 and the condenser side pressure guide plate 3; a refrigerant circulation pipeline is mounted on the dimensional detection assembly; wherein, the refrigerant circulation pipeline includes a main pipeline 4 mounted on the dimensional detection assembly, and a first sub-pipeline 5 and a second sub-pipeline 6 are respectively mounted at both ends of the main pipeline 4, the end of the first sub-pipeline 5 resting on the compressor side pressure column 2, and the end of the second sub-pipeline 5 resting on the condenser side pressure guide plate 3.

[0030] The above scheme is used as follows: During the dimensional inspection of the refrigerant circulation pipeline, the base plate 1 is placed on the final inspection station of the production line, and then the main pipeline 4 is placed on the dimensional inspection assembly. The end of the first sub-pipeline 5 is placed on the compressor side pressure column 2, and the end of the second sub-pipeline 6 is placed on the condenser side pressure guide plate 3. This is used to install the refrigerant circulation pipeline for easy inspection. Subsequently, measuring tools such as rulers and feeler gauges are used to measure the dimensions of the refrigerant circulation pipeline. This inspection method can effectively identify unqualified pipelines and further improve the dimensional inspection efficiency.

[0031] Furthermore, the dimension detection component includes a first inclined surface 7 formed on the compressor side pressure column 2, on which a first compressor ruler plate 8 is installed; the first compressor ruler plate 8 is longitudinally installed on the first inclined surface 7, and a second compressor ruler plate 9 is installed on one side of the first compressor ruler plate 8; the second compressor ruler plate 9 is transversely installed on the first inclined surface 7; the end of the first sub-body pipe 5 is placed on the first inclined surface 7, and the two side walls of its end are respectively attached to the first compressor ruler plate 8 and the second compressor ruler plate 9.

[0032] Furthermore, the size detection component also includes a groove 10 formed on the condenser side pressure plate 3, and the end of the second sub-rod is placed in the groove 10.

[0033] Furthermore, a hose gauge 11 is installed on the base plate 1; the hose gauge 11 is located between the compressor side pressure column 2 and the condenser side pressure guide plate 3, and a straight groove 12 is opened on the hose gauge 11; the main pipeline 4 is located in the straight groove 12, and a hose cover plate 13 is installed on the upper surface of the hose gauge 11, and a pressure plate 14 is provided on the hose cover plate 13; the two sides of the pressure plate 14 are connected to the hose gauge 11 by bolts.

[0034] Furthermore, a first guide ruler 15 is installed between the hose gauge 11 and the condenser side pressure guide ruler plate 3, and the first guide ruler 15 is installed on the base plate 1; the second sub-pipe 6 is mounted on the first guide ruler 15.

[0035] The above scheme is adopted as follows: In use, the main pipe 4 is placed in the straight groove 12 of the hose gauge 11, and then the hose cover plate 13 is inserted into the square groove above the hose gauge 11. The pressure plate 14 then presses the hose cover plate 13 to fix its position. The end of the first sub-pipe is placed on the first inclined surface 7 and is positioned by the first compressor straightedge 8 and the second compressor straightedge plate 9. The end of the second sub-pipe 6 is placed in the inclined groove 10 of the condenser side pressure straightedge plate 3, and part of its rod is mounted on the first straightedge 15. This is used to install the refrigerant circulation pipe. After the refrigerant circulation pipe is installed, the gaps between the main pipe 4, the first sub-pipe 5, the second sub-pipe 6 and the relevant straightedge plates and gauges are measured using rulers, feeler gauges and other measuring tools. The dimensional errors of these gaps need to be compared with the allowable range specified on the design drawings to determine whether they meet the standards.

[0036] It should be noted that:

[0037] First, when inspecting the distance of the curved section of the refrigerant circulation pipeline, the criterion is whether the error is within the allowable range specified in the refrigerant circulation pipeline drawing A, thereby determining whether it is qualified.

[0038] Secondly, the dimensional gauge is designed with a detection error range of ±0.5mm, which meets the allowable error range specified in drawing A of the refrigerant circulation pipeline from the compressor to the condenser. This ensures the accuracy of the refrigerant circulation pipeline dimension measurement. Therefore, the gauge is reasonably designed, has a simple and reliable structure, and does not deform. It is not only suitable for the final inspection station on the product production line, but also for the re-inspection of products before they leave the factory, and has good practicality.

[0039] The working principle of this utility model:

[0040] During the dimensional inspection of the refrigerant circulation pipeline, the base plate 1 is placed on the final inspection station of the production line. The main pipeline 4 is placed in the straight groove 12 of the hose gauge 11. Then, the hose cover plate 13 is inserted into the square groove above the hose gauge 11. The pressure plate 14 then presses the hose cover plate 13 to fix its position. The end of the first sub-pipeline is placed on the first inclined surface 7 and positioned by the first compressor straightedge 8 and the second compressor straightedge plate 9. The end of the second sub-pipeline 6 is placed in the inclined groove 10 of the condenser side pressure straightedge plate 3, and part of its rod is mounted on the first straightedge 15. This is how the refrigerant circulation pipeline is installed. After the refrigerant circulation pipeline is installed, the gaps between the main pipeline 4, the first sub-pipeline 5, the second sub-pipeline 6 and the relevant straightedge plates and gauges are measured using rulers, feeler gauges and other measuring tools. The dimensional errors of these gaps need to be compared with the allowable range specified on the design drawings to determine whether they meet the standards.
