Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to a tooling device for precise positioning of a bottle body. Background Technology
[0002] In the efficient and stable operation of automotive air conditioning systems, the receiver-drier plays a core and crucial role, serving as a vital functional component to ensure system performance and reliability. Its importance is reflected in several key aspects. It not only stores and dynamically regulates the refrigerant within the air conditioning system, ensuring a stable and continuous refrigerant supply even during significant changes in system load, such as vehicle start-up, acceleration, or drastic fluctuations in ambient temperature, thus maintaining normal system operation, but also, through its carefully designed desiccant and filter structure, effectively removes moisture from the refrigerant and impurities from the piping. This function prevents serious problems caused by moisture, such as ice blockage and corrosion, while also preventing impurities from clogging the expansion valve or damaging the compressor. It creates a dry and clean operating environment for the air conditioning system, directly and significantly impacting the system's cooling efficiency and lifespan.
[0003] However, the existing methods for assembling and securing traditional liquid receiver desiccant bottles have certain limitations. Currently, the common method is to directly bind the bottle with straps to achieve initial positioning. While this method can meet basic securing requirements to some extent, it exposes several significant problems in practical applications. First, the binding force is difficult to control. Due to the lack of scientific and effective control methods, operators often rely on experience, resulting in inconsistent and inaccurate binding force. If the binding is too loose, the bottle may loosen due to vibration during vehicle operation; if it is too tight, it may damage the bottle and affect its normal function. Second, the cylindrical structure and smooth surface of the bottle make it lack effective positioning features during binding. This makes it prone to circumferential rotation or axial displacement, making precise securing difficult. Prolonged exposure to this unstable state, exacerbated by vehicle vibrations, can cause the straps to gradually loosen, potentially leading to the bottle detaching. Loosening or detachment of the bottle can have serious negative impacts on the vehicle's air conditioning system. It can directly compromise the system's seal, leading to refrigerant leakage, which in turn causes abnormal system pressure, a significant decrease in cooling performance, or even complete failure. More seriously, refrigerant leaks can also pose safety hazards, threatening the health and safety of vehicle occupants.
[0004] In summary, there is room for improvement and optimization in the existing assembly and fixing methods of traditional liquid storage desiccant bottles to enhance the stability, reliability, and safety of automotive air conditioning systems. Utility Model Content

[0030] A. Storage drying bottle. Detailed Implementation
[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0032] like Figure 1 and Figure 4 As shown, this utility model claims protection for a bottle body precision positioning tooling device, which mainly includes a base plate 1, a fixed limiting mechanism 2, a movable pressing mechanism 3, and a product tray 4. The fixed limiting mechanism 2 is located on the first side of the base plate 1, the movable pressing mechanism 3 is located on the second side of the base plate 1, and the product tray 4 is located between the fixed limiting mechanism 2 and the movable pressing mechanism 3, and is used to place the liquid storage drying bottle A.
[0033] In this embodiment, the lower surface of the base plate 1 is a flat mounting surface, which is parallel to the second positioning plane 2012 of the L-shaped positioning plate 201 in the fixing and limiting mechanism 2. The bottom of the L-shaped positioning plate 201 is firmly fixed to the base plate 1 by bolts or welding. It has a horizontally extending first positioning plane 2011 and a second positioning plane 2012 extending vertically upward from the first positioning plane 2011. As shown in the figure, the first positioning plane 2011 provides horizontal support for the liquid storage drying bottle A, while the second positioning plane 2012 is used for side positioning.
[0034] One technical feature of this invention is that an anti-misalignment positioning structure is provided on the second positioning plane 2012 protruding towards the movable pressing mechanism 3. This structure consists of a first protruding post 5 and a second protruding post 6. The diameter of the first protruding post 5 is larger than the diameter of the second protruding post 6, and the vertical distance between the top of the first protruding post 5 and the second positioning plane 2012 is L1, while the vertical distance between the top of the second protruding post 6 and the second positioning plane 2012 is L2, where L1>L2. This design effectively prevents incorrect installation of the liquid storage drying bottle A. The bottom of the liquid storage drying bottle A has corresponding holes that match the size and position of the first protruding post 5 and the second protruding post 6. In other words, the first protruding post 5 and the second protruding post 6 are set with reference to two holes already present on the bottom of the liquid storage drying bottle A to achieve the positioning purpose.
[0035] The second positioning plane 2012 has a recessed first mounting hole 20121 and a second mounting hole 20122. The first protruding post 5 is fixedly installed in the first mounting hole 20121 by an interference fit, and the second protruding post 6 is also fixedly installed in the second mounting hole 20122. Both the first mounting hole 20121 and the second mounting hole 20122 have stepped surfaces to limit the protruding posts and ensure the stability and accuracy of the installation of the protruding posts.
[0036] Product tray 4 is positioned between fixed limiting mechanism 2 and movable clamping mechanism 3, and its function is to support the liquid storage desiccant bottle A. The upper surface of product tray 4 has a positioning arc surface 401 that matches the shape of the liquid storage desiccant bottle A. This positioning arc surface 401 is a semi-circular arc surface that matches the diameter of the bottle body of the liquid storage desiccant bottle A, and the central axis of the semi-circular arc surface is parallel to the second positioning plane 2012. This design allows the liquid storage desiccant bottle A to be stably placed on product tray 4 and to match the positions of fixed limiting mechanism 2 and movable clamping mechanism 3. Simultaneously, the axial distance between the first protrusion 5 and the second protrusion 6 is smaller than the radius of curvature of the upper semi-circular arc surface of product tray 4. This ensures that when the liquid storage desiccant bottle A is lowered along the arc surface and pushed towards the second positioning plane 2012, the bottom of the bottle can simultaneously contact the first protrusion 5 and the second protrusion 6 and slide into position, avoiding one-sided jamming due to excessive distance and further ensuring positioning accuracy.
[0037] A pad 7 is fixedly mounted on the base plate 1, and the movable clamping mechanism 3 is fixedly mounted on the pad 7 by bolts or other means. Specifically, the movable clamping mechanism 3 includes a fixed seat 301, a sleeve 302, a top rod 303, and a connecting rod structure. The fixed seat 301 includes a mounting plate 3011, which is detachably fixed to the pad 7 by bolts, facilitating the installation, disassembly, and maintenance of the movable clamping mechanism 3.
[0038] The sleeve 302 is mounted on the fixed base 301, providing a sliding track for the push rod 303. The push rod 303 is horizontally slidably inserted into the sleeve 302, and a buffer pad 8 is connected to the end of the push rod 303 near the fixed limiting mechanism 2. The buffer pad 8 can prevent damage to the bottle body when the push rod 303 presses against the liquid storage drying bottle A.
[0039] Furthermore, the linkage structure includes a handle and a connector 306. The handle includes a first rod 304 and a second rod 305 arranged perpendicularly to each other. The second rod 305 is hinged to the fixed base 301. One end of the connector 306 is hinged to the joint between the first rod 304 and the second rod 305, and the other end is hinged to the end of the top rod 303. The free end of the first rod 304 is connected to a non-slip handle 9 for easy rotation of the handle by the operator.
[0040] The working principle of this utility model is as follows: When it is necessary to position the liquid storage drying bottle A, first place the liquid storage drying bottle A on the positioning arc surface 401 of the product tray 4 and push it to one side of the second positioning plane 2012 so that one side of the liquid storage drying bottle A is in contact with the second positioning plane 2012 of the fixed limiting mechanism 2. At the same time, make the first protrusion 5 and the second protrusion 6 of the error-proof positioning structure cooperate with the corresponding holes on the liquid storage drying bottle A to ensure the correct installation direction. Then, the operator holds the anti-slip handle 9 and rotates the handle. When the handle rotates, it drives the top rod 303 to move axially along the sleeve 302 through the connector 306. When the end of the top rod 303 presses against the liquid storage drying bottle A, the axis of the top rod 303, the axis of the connector 306, and the axis of the second rod 305 are collinear, and this collinearity passes through the hinge point of the second rod 305 on the fixed seat 301. At this time, the movable clamping mechanism 3 is in a stable clamping state, realizing the precise positioning of the liquid storage drying bottle A. In this design, since the axis of the top rod 303, the axis of the connector 306, and the axis of the second rod 305 are collinear when in the clamping state, the reaction force of the liquid storage drying bottle A on the top rod 303 is along the length direction of the second rod 305, that is, there is no lateral deviation. Therefore, the handle will not easily reverse and cause loosening, and the clamping effect is good. When it is necessary to remove the liquid storage drying bottle A, turn the handle in the opposite direction. The push rod 303 will retract under the action of the connecting rod structure, releasing the clamping force on the liquid storage drying bottle A, and then the liquid storage drying bottle A can be taken out.
[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
