Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning system component manufacturing technology, and in particular relates to a C-dimensional gauge for the refrigerant circulation pipeline from the refrigerator to the compressor. Background Technology

[0002] An automotive air conditioning system consists of heating, cooling, air purification, and control systems. The cooling system comprises a refrigerant (evaporator), compressor, condenser, expansion valve, receiver-drier, and connected high and low pressure refrigerant circulation lines. Its main function is to regulate and control the temperature and humidity of the air entering the vehicle's interior from the outside. The circulating refrigerant within the system absorbs and dissipates heat from the air passing through the refrigerant (evaporator) and condenser (heat exchange method) to provide a comfortable driving and riding environment for the driver and passengers.

[0003] The flexible low-pressure pipe assembly for heavy-duty truck air conditioning—from the refrigerant to the compressor C—is a key component of a heavy-duty truck air conditioning refrigeration system. It is the low-pressure pipeline component connecting the refrigerant to the compressor in the refrigeration system. Due to the different installation locations of the refrigerant (evaporator), condenser, expansion valve, and compressor in automotive air conditioning systems, as well as space constraints, the refrigerant circulation pipelines connecting them are very tortuous and complex. Therefore, the designed pipeline routing is also varied and winding. Using conventional measuring tools to inspect dimensions during the manufacturing process presents many difficulties, makes it hard to guarantee product measurement quality and accuracy, and is very time-consuming, affecting testing efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a C-dimensional gauge for the refrigerant circulation pipeline from the refrigerator to the compressor. It has the advantages of convenient operation, saving time and effort, facilitating one-time measurement of the full-size pipeline, ensuring measurement accuracy and consistency, and improving inspection efficiency. It solves the problems of conventional measuring tools in the prior art being time-consuming and labor-intensive, making it difficult to perform one-time measurement of the full-size pipeline, and making it difficult to ensure measurement accuracy and consistency, thus affecting the efficiency of inspection work.

[0005] This utility model is implemented as follows: a dimensional gauge for the refrigerant circulation pipeline C from a refrigerator to a compressor includes a base plate and a refrigerant circulation pipeline C body. The top of the base plate is fixedly mounted with a refrigerator side pressure plate ruler, a first gauge, a second gauge, a refrigerator side hose gauge, a compressor pressure plate ruler, a compressor side hose gauge, and a third gauge by hexagonal bolts. The refrigerator side pressure plate ruler, the first gauge, the second gauge, the refrigerator side hose gauge, the compressor pressure plate ruler, the compressor side hose gauge, and the third gauge are distributed along the pipeline path of the refrigerant circulation pipeline C body. The refrigerant circulation pipeline C body is snapped between the tops of the refrigerator side pressure plate ruler, the first gauge, the second gauge, the refrigerator side hose gauge, the compressor pressure plate ruler, the compressor side hose gauge, and the third gauge.

[0006] This setup significantly reduces the time required for full-size product inspection, ensuring measurement accuracy, consistency in batch measurements and product consistency. Furthermore, full-size product inspection can be completed in one operation, meeting the needs of mass production lines. It features a simple structure, convenient and time-saving operation, resistance to deformation, durability, and improved efficiency, all of which contribute to ensuring measurement accuracy and consistency.

[0007] As a preferred embodiment of this utility model, the top of the base plate is provided with an installation groove, and the refrigerator side pressure plate ruler, the first ruler, the second ruler, the refrigerator side hose ruler, the compressor pressure plate ruler, the compressor side hose ruler and the third ruler are fixed in the corresponding installation groove by hexagonal bolts.

[0008] This design ensures the accuracy and stability of the installation position of the straightedge and measuring gauge. The mounting groove serves as a positioning reference to prevent displacement of the straightedge and measuring gauge during use, thereby improving detection accuracy. The mounting groove, in conjunction with the hexagonal bolts, enables the straightedge and measuring gauge to be detachably fixed, facilitating later maintenance, replacement, and position adjustment, making it flexible in use.

[0009] As a preferred embodiment of this utility model, the top of the refrigerator side pressure plate ruler, the first ruler, the second ruler, the refrigerator side hose ruler, the compressor pressure plate ruler, the compressor side hose ruler, and the third ruler are all provided with placement grooves, and the refrigerant circulation pipeline C body is snapped into the placement grooves.

[0010] This setup ensures that the placement slot matches the outer contour of the refrigerant circulation pipeline C, allowing the pipeline to be accurately clamped onto the fixture. This facilitates limiting the lateral and longitudinal displacement of the pipeline. Through the coordinated positioning of multiple placement slots, it also facilitates the detection of pipeline shape deviations, bending angles, and spacing between sections, enabling a one-time measurement of the entire pipeline size. This helps ensure the accuracy and consistency of the measurement and improves the efficiency of the inspection work.

[0011] As a preferred embodiment of this utility model, the refrigerator side pressure plate ruler, base plate, first measuring tool, second measuring tool, refrigerator side hose measuring tool, compressor pressure plate ruler, compressor side hose measuring tool, and third measuring tool are all made of aluminum alloy profiles.

[0012] With this setup, the entire fixture is made of aluminum alloy profiles. Taking advantage of the lightweight, high strength and corrosion resistance of aluminum alloy, it is easy to operate, reduces labor intensity, helps extend the service life of the fixture, ensures the dimensional accuracy and surface quality of the fixture, and improves the reliability of the inspection.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: it facilitates the shortening of the full-size inspection time of products, ensures measurement accuracy, guarantees the measurement consistency and product consistency of batch products, and the full-size inspection and measurement of products can be completed in one go, meeting the needs of batch production line operation. It has a simple structure, is convenient to operate, saves time and effort, is not easily deformed, is sturdy and durable, helps to ensure the accuracy and consistency of measurement, and improves the efficiency of inspection work.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] refer to Figures 1 to 5As shown in the figure, an embodiment of the present invention provides a dimensional gauge for the refrigerant circulation pipeline C from the refrigerator to the compressor, including a base plate 2 and a refrigerant circulation pipeline C body 11. The top of the base plate 2 is fixedly installed with a refrigerator side pressure plate ruler 1, a first gauge 3, a second gauge 4, a refrigerator side hose gauge 5, a compressor pressure plate ruler 6, a compressor side hose gauge 7, and a third gauge 8 by hexagonal bolts. The refrigerator side pressure plate ruler 1, the first gauge 3, the second gauge 4, the refrigerator side hose gauge 5, the compressor pressure plate ruler 6, the compressor side hose gauge 7, and the third gauge 8 are distributed along the pipeline path of the refrigerant circulation pipeline C body 11. The refrigerant circulation pipeline C body 11 is snapped between the tops of the refrigerator side pressure plate ruler 1, the first gauge 3, the second gauge 4, the refrigerator side hose gauge 5, the compressor pressure plate ruler 6, the compressor side hose gauge 7, and the third gauge 8.

[0023] By adopting the above solution, the inspection time for the full dimensions of the product can be greatly shortened, the measurement accuracy can be guaranteed, the measurement consistency and product consistency of batch products can be guaranteed, and the full-dimensional inspection and measurement of the product can be completed in one go, meeting the needs of batch production line operation. The structure is simple, the operation is convenient, time-saving and labor-saving, it is not easily deformed, it is sturdy and durable, which helps to ensure the accuracy and consistency of measurement and improve the efficiency of inspection work.

[0024] Specifically, the top of the base plate 2 is provided with an installation groove 9, and the refrigerator side pressure plate ruler 1, the first ruler 3, the second ruler 4, the refrigerator side hose ruler 5, the compressor pressure plate ruler 6, the compressor side hose ruler 7 and the third ruler 8 are fixed in the corresponding installation groove 9 by hexagonal bolts.

[0025] The above scheme ensures the accuracy and stability of the installation position of the straightedge and measuring gauge. The mounting groove 9 serves as a positioning reference to prevent displacement of the straightedge and measuring gauge during use and improves the detection accuracy. The mounting groove 9, in conjunction with the hexagonal bolts, enables the straightedge and measuring gauge to be detachably fixed, facilitating later maintenance, replacement, and position adjustment, and making it flexible in use.

[0026] Specifically, the tops of the refrigerator side pressure plate ruler 1, the first ruler 3, the second ruler 4, the refrigerator side hose ruler 5, the compressor pressure plate ruler 6, the compressor side hose ruler 7, and the third ruler 8 are all provided with placement slots 10, and the refrigerant circulation pipeline C body 11 is snapped into the placement slots 10.

[0027] Using the above scheme, the placement groove 10 matches the outer contour of the refrigerant circulation pipeline C, so that the pipeline can be accurately clamped onto the fixture, which facilitates the restriction of the lateral and longitudinal displacement of the pipeline. Through the coordinated positioning of multiple sets of placement grooves 10, it is also convenient to detect the shape deviation, bending angle and spacing of each section of the pipeline, so as to realize the one-time measurement of the full-size pipeline, which helps to ensure the accuracy and consistency of the measurement and improve the efficiency of the inspection work.

[0028] Specifically, the refrigerator side pressure plate ruler 1, base plate 2, first gauge 3, second gauge 4, refrigerator side hose gauge 5, compressor pressure plate ruler 6, compressor side hose gauge 7, and third gauge 8 are all made of aluminum alloy profiles.

[0029] The above solution uses aluminum alloy profiles for the entire inspection fixture. The lightweight, high strength and corrosion resistance of aluminum alloy make it easy to operate, reduce labor intensity, extend the service life of the inspection fixture, ensure the dimensional accuracy and surface quality of the inspection fixture, and improve the reliability of the inspection.

Use a ruler and feeler gauge to measure the gap between each straightedge and the interface between the refrigerant and compressor pressure plates of the pipeline being inspected, the gap between the semi-circular arc of each gauge and the interface between the soft (rubber hose) and hard (aluminum) tubes, and whether the dimensional error of the distance from the vertical surface of the gauge to the bend of the pipeline is within the allowable range specified in the drawing of the refrigerant circulation pipeline C body 11. This is used to determine whether the product is qualified.

[0032] The inspection fixture of this device is designed with an error range of ±0.5mm, which meets the allowable error range specified in the drawing of the refrigerant circulation pipeline C body 11. It can ensure the dimensional measurement accuracy of the refrigerant circulation pipeline C body 11, facilitate the reduction of the full-size inspection time of the product, ensure the measurement consistency and product consistency of batch products, and complete the full-size inspection measurement of the product in one go, meeting the needs of batch production line operation.
