Description

Technical Field

[0001] This utility model belongs to the technical field of refrigerant circulation pipeline from refrigerator to compressor, and particularly relates to a dimension gauge for refrigerant circulation pipeline from refrigerator to compressor. Background Technology

[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 through the refrigerant. This air can come from inside the vehicle or from outside. The circulating refrigerant in the cooling system absorbs heat from the air passing through the refrigerant (evaporator) inside the vehicle's interior, and then uses the condenser to exchange heat through condensation (heat dissipation), thereby creating a comfortable driving environment for the driver and passengers.

[0003] The A-type flexible low-pressure pipe assembly from the air conditioner refrigeration unit to the compressor in heavy-duty trucks is a key component of the air conditioning system. It plays a crucial role in the low-pressure piping between the refrigeration unit and the compressor. In automotive air conditioning systems, the installation positions of components such as the refrigeration unit (evaporator), condenser, expansion valve, and compressor vary. Coupled with space constraints, the interconnected refrigerant circulation piping routes are extremely tortuous and complex. Therefore, the piping route of this low-pressure pipe assembly is designed to be curved and varied. During the manufacturing stage, using conventional measuring tools to inspect its dimensions presents many difficulties, making it hard to ensure product consistency and dimensional accuracy. Moreover, it is extremely time-consuming, which in turn adversely affects the production schedule. Utility Model Content

[0026] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 4This utility model provides a dimensional gauge for a refrigerant circulation pipeline A from a refrigerator to a compressor, comprising a base plate 1, which is L-shaped; a compressor side pressure plate 2 is mounted on the upper side of the base plate 1, located on the left side of the base plate 1; a refrigerator side pressure plate 3 is mounted on the side of the base plate 1 away from the compressor side pressure plate 2, and both the refrigerator side pressure plate 3 and the compressor side pressure plate 2 have placement grooves 4; a dimensional measuring element is mounted on the base plate 1; a refrigerant circulation pipe is mounted on the dimensional measuring element; wherein, the refrigerant circulation pipeline includes a main pipe 5, which is located on the dimensional measuring element, and a first sub-pipe 6 and a second sub-pipe 7 are respectively mounted on both ends of the main pipe 5, the end of the first sub-pipe 6 being located on the compressor pressure plate 2, and the end of the second sub-pipe 7 being located on the refrigerator side pressure plate 3.

[0029] The above solution involves the following steps during the refrigerant circulation pipeline dimensional inspection: First, the base plate 1 is installed on the final inspection station of the production line. Then, the refrigerant circulation pipeline to be inspected is placed on the base plate 1, ensuring that its main tube 5 is positioned on the dimensional inspection piece. Next, the end of the first sub-tube 6 is placed into the placement slot 4 on the compressor side pressure plate 2, while the end of the second sub-tube 7 is placed into the placement slot 4 on the refrigeration machine side pressure plate 3. In this way, the refrigerant circulation pipeline is fixed in an appropriate position, facilitating accurate dimensional measurement using measuring tools such as rulers and feeler gauges. This allows for the determination of whether the refrigerant circulation pipeline is qualified, further improving the inspection efficiency of the refrigerant circulation pipeline and demonstrating good practicality.

[0030] Furthermore, the size detection component includes a hose gauge 8 fixedly connected to the base plate 1; the hose gauge 8 is located between the compressor side pressure plate 2 and the refrigeration machine side pressure plate 3, and the hose gauge 8 has a first straight groove 9 corresponding to the shape of the main tube 5; the main tube 5 is located in the first straight groove 9.

[0031] Furthermore, the size detection component also includes a first gauge 10 fixedly connected to the base plate 1; the first gauge 10 is located between the compressor pressure measuring plate and the hose gauge 8, and the first gauge 10 has an inclined groove 11; the first sub-tube 6 is mounted in the inclined groove 11.

[0032] Furthermore, the size detection component also includes a second gauge 12 fixedly connected to the base plate 1; the second gauge 12 is located between the refrigeration unit side pressure plate 3 and the hose gauge 8, and a second straight groove 13 is provided on the second gauge 12; the second sub-tube 7 is mounted on the second gauge 12.

[0033] Using the above scheme: During the dimensional inspection of refrigerant circulation pipeline A, the main tube 5 is placed in the first straight groove 9, while the ends of the first sub-tube 6 and the second sub-tube 7 are located on the placement groove 4. Part of the first sub-tube 6 will contact the inclined groove 11 of the first measuring tool 10, and part of the second sub-tube 7 will contact the second straight groove 13 of the second measuring tool 12. By using measuring tools such as rulers and feeler gauges, the gaps between the main tube 5, the first sub-tube 6, and the second sub-tube 7 and their respective measuring grooves can be accurately measured. The dimensional errors of these gaps need to be compared with the allowable range specified on the drawings to ensure that the product meets the design standards.

[0034] It should be noted that:

[0035] 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.

[0036] Secondly, the design inspection error range of the hose gauge 8, the first gauge 10 and the second gauge 12 is within ±0.5mm, which meets the allowable error range specified in the drawing A of the refrigerant circulation pipeline from the refrigerator to the compressor. This ensures the accuracy of the refrigerant circulation pipeline size measurement. Therefore, the gauge has a simple and reliable structure, does not deform, and is suitable not only for the final inspection station of the product production line, but also for the re-inspection of the product before it leaves the factory, thus having good practicality.

[0037] Third, the aforementioned components, such as the rubber hose gauge 8, are connected to the base plate 1 by bolts.

[0038] Furthermore, both the first sub-tube 6 and the second sub-tube 7 are arc-shaped.

[0039] The working principle of this utility model:

[0040] During the refrigerant circulation pipeline dimensional inspection process, the base plate 1 is first installed on the final inspection station of the production line. Then, the refrigerant circulation pipeline to be inspected is placed on the base plate 1. The main body pipe 5 is placed in the first straight groove 9, while the ends of the first sub-pipe 6 and the second sub-pipe 7 are located on the placement groove 4. Part of the first sub-pipe 6 will contact the inclined groove 11 of the first gauge 10, and part of the second sub-pipe 7 will contact the second straight groove 13 of the second gauge 12. By using measuring tools such as rulers and feeler gauges, the gaps between the main body pipe 5, the first sub-pipe 6, and the second sub-pipe 7 and their respective gauge grooves can be accurately measured. The dimensional errors of these gaps need to be compared with the allowable range specified on the drawings to ensure that the product meets the design standards.
