Abstract
Description
Technical Field
[0001] This utility model relates to the field of airbag support technology for air suspension systems, and more specifically, to a double airbag support inspection tool. Background Technology
[0002] Air suspension has been increasingly widely used in vehicles due to its unique advantages. The main function of the airbag support in the suspension system is to bear the suspension load. As an important connecting component of the suspension, the airbag support transmits force while providing installation space for the airbag.
[0003] The complex stress on the chassis suspension causes the airbag support to bear loads under various working conditions. Existing airbag supports can generally only connect a single airbag, lacking airbag supports that can connect two airbags, and there is a lack of testing for dual airbag supports, especially the testing of the workpiece proportion and hole position ratio. Utility Model Content
[0004] To address at least one of the aforementioned problems, this utility model first provides a dual-airbag support fixture, comprising a dual-airbag support, a fixture base, a first detection element, a second detection element, a first mating element, and a second mating element. The dual-airbag support is detachably connected to the fixture base. The first and second detection elements are both fixed on the fixture base. The first and second mating elements are both inserted into or threadedly connected to the dual-airbag support. The first detection element is adapted to abut against the first mating element from above and below. The second mating element is limited and abuts against the first and second detection elements.
[0005] Optionally, the base of the inspection fixture is provided with a first mounting hole, the bottom of the first inspection piece is provided with a first protrusion, the first protrusion is installed in the first mounting hole, and both the first inspection piece and the first protrusion are cylindrical.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] This utility model embodiment provides a double airbag support fixture, combined with Figures 1 to 4 As shown, the system includes a double-airbag support 1, a fixture base 2, a first inspection component 3, a second inspection component 4, a first mating component 5, and a second mating component 6. The double-airbag support 1 and the fixture base 2 are detachably connected, facilitating the inspection of the double-airbag support 1. The first inspection component 3 and the second inspection component 4 are both securely mounted on the fixture base 2, providing a stable and reliable reference surface for the entire inspection system, effectively preventing measurement deviations and ensuring the consistency of inspection results. The first mating component 5 and the second mating component 6 are connected to the double-airbag support 1 via plug-in or threaded connections, achieving both rapid assembly and high-precision positioning between the connecting components. The first inspection component 3 and the first mating component 5 engage in a vertical abutment mechanism to accurately inspect the installation height and flatness of the double-airbag support 1 in the vertical direction. The second mating component 6 is confined between the first inspection component 3 and the second inspection component 4, forming a circumferential constraint on the double-airbag support 1 in the horizontal direction, used to determine whether there are production ratio deviations or bending deviations, thereby achieving multi-directional rapid inspection of the workpiece and improving inspection efficiency and accuracy.
[0023] like Figure 3 As shown, optionally, a first mounting hole 21 is provided on the fixture base 2, and a matching first protrusion 32 is designed on the bottom of the first inspection piece 3. Positioning and fixing are achieved through the tight fit between the protrusion and the mounting hole. Both the first inspection piece 3 and the first protrusion 32 adopt a cylindrical structure. This shape is non-directional and easy to manufacture with precision. It can automatically center, effectively eliminating errors caused by installation tilt or torsion, and further enhancing the reliability of the inspection results.
[0024] like Figure 3As shown, optionally, the fixture base 2 is also provided with a second mounting hole 22, and the bottom of the second detection element 4 is provided with a second protrusion 41, which is used to mount it to the base. The second detection element 4 and the second protrusion 41 adopt a cuboid structure. This shape has a large contact surface and anti-overturning moment, which is more effective when facing the lateral force generated during the detection process, and can keep the second detection element 4 stable, thereby ensuring the accuracy and reliability of the limit detection function.
[0025] like Figure 4 As shown, optionally, the first mating part 5 is provided with a first connecting post 52, the second mating part 6 is provided with a second connecting post (not shown), and the dual airbag support 1 is provided with a third mounting hole 11 and a fourth mounting hole 12. The diameter of the first connecting post 52 is adapted to the third mounting hole 11, and the diameter of the second connecting post is adapted to the fourth mounting hole 12, thereby detecting the size of the third mounting hole 11 and the fourth mounting hole 12 during the connection process.
[0026] like Figure 4 As shown, optionally, external threads are machined on the bottom of the peripheral walls of the first connecting post 52 and the second connecting post, while the third mounting hole 11 and the fourth mounting hole 12 on the dual airbag support 1 are both provided with internal threads. The threaded connection provides a strong locking force, effectively preventing the mating parts from loosening or falling off under the vibration environment of repeated testing operations, reducing the risk of misjudgment due to loose parts. At the same time, the external thread only located at the bottom of the first connecting post 52 reduces the number of rotations during installation, saving installation time while maintaining the threaded locking effect, thus improving installation and testing efficiency.
[0027] like Figure 1 As shown, optionally, the first mating part 5 is provided with a first positioning hole 51, and the first detection part 3 is provided with a second positioning hole 31. The third mounting hole 11, the first positioning hole 51, and the second positioning hole 31 are positioned by a positioning pin. Positioning by a three-hole pin is not only quick and convenient, but this mechanical hard positioning method can also determine whether the hole shaft production position is accurate and judge whether the product is qualified.
[0028] like Figure 2 As shown, optionally, all sharp edges of the first detection component 3, the second detection component 4, the first mating component 5, and the second mating component 6 are chamfered. This eliminates sharp edges, greatly improving the safety of the operator's hands, avoiding the risk of scratches, and also preventing the surface of the dual airbag support 1 from being scratched during the inspection process. Secondly, the chamfering facilitates the introduction of parts during the assembly process, especially when the first mating component 5 and the second mating component 6 are introduced into the third mounting hole 11 and the fourth mounting hole 12 respectively, guiding the parts into place smoothly, improving assembly efficiency, and protecting the mating surfaces from damage.
[0029] like Figure 1 As shown, optionally, ergonomic handles 23 are fixedly installed at both ends of the fixture base 2. The addition of handles 23 makes the moving and transfer of the fixture very labor-saving and convenient, and is especially suitable for use between different workstations on the production line.
[0030] like Figure 2 As shown, optionally, four first mating parts 5 are provided, symmetrically arranged in pairs on the double airbag support 1; two second mating parts 6 are provided, also symmetrically distributed. This symmetrical layout ensures that the double airbag support 1 is subjected to uniform clamping force and positioning constraint during testing, effectively preventing workpiece deformation or testing distortion caused by uneven force.
[0031] like Figure 1 As shown, optionally, a precision-machined positioning post 24 is fixedly installed on the fixture base 2, and a connecting hole 13 is precisely machined on the double airbag support 1. Through the insertion and engagement of the positioning post 24 and the connecting hole 13, rapid and accurate initial positioning of the double airbag support 1 on the fixture base 2 is achieved. The operator can easily place the support in the correct position without repeated adjustments, greatly saving positioning time and improving inspection efficiency.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
