[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.
[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] The current assembly process of the shock absorber hose airbag includes: manually selecting and installing pads, adjusting the level of the pressure plates of the two clamps, then applying glue, manually using the two clamps to press the airbag, starting a 45-second timer, and after the timer ends, checking the airtightness of the processed airbag.
[0037] Due to design limitations of the clamps, manually adjusting the level of the two clamp plates is difficult, leading to uneven force on the four corners of the airbag and potentially causing leakage, posing a significant quality risk. Furthermore, manually adjusting the level and manually using a stopwatch are inefficient methods.
[0038] To address the aforementioned issues, this application provides an airbag clamping fixture that replaces manual airbag clamping, automatically clamps the airbag, reduces labor costs, ensures even force distribution during airbag clamping, and reduces airbag failures.
[0039] like Figures 1-3 As shown in an illustrative embodiment of the airbag clamping fixture of this utility model, the airbag clamping fixture is used to clamp the airbag to be processed, and includes a bracket, a cylinder 1, an upper pressure plate 3, and a lower pressure plate 7. The airbag clamping fixture is installed on a horizontal plane, with the bottom closest to the horizontal plane and the top furthest from the horizontal plane. The direction of the top is upward, and the direction of the bottom is downward.
[0040] The support includes a crossbeam 9 and a column 10 that are perpendicularly connected to each other. The top of the column 10 is connected to the crossbeam 9, and the bottom is connected to the pressure plate 7.
[0041] Cylinder 1 includes a cylinder barrel and a piston rod. Cylinder 1 is vertically arranged and perpendicular to the crossbeam 9. The cylinder barrel is connected to the crossbeam 9, and the piston rod moves inside the cylinder barrel.
[0042] Cylinder 1 is located above crossbeam 9.
[0043] The upper pressure plate 3 is a flat plate, parallel to the crossbeam 9. The side of the upper pressure plate 3 closest to the cylinder 1 is connected to the piston rod of the cylinder 1. The upper pressure plate 3 moves with the piston rod toward the lower pressure plate 7, contacting the air bag to be processed. Alternatively, the upper pressure plate 3 moves with the piston rod away from the lower pressure plate 7, away from the air bag to be processed.
[0044] The lower pressure plate 7 holds the airbag to be processed and is spaced apart from the upper pressure plate 3, located on the side of the upper pressure plate 3 away from the cylinder 1.
[0045] The lower pressure plate 7 is parallel to the upper pressure plate 3 and is located below the upper pressure plate 3.
[0046] The piston rod can drive the upper pressure plate 3 to move closer to the lower pressure plate 7 and contact the airbag to be processed.
[0047] By using cylinder 1 to drive the upper pressure plate 3 and lower pressure plate 7 to cooperate, stable clamping of the airbag is achieved. Compared with the traditional manual clamping method, the pressure is uniform and controllable, which can improve the accuracy and quality of airbag processing. The structural design of the bracket ensures the overall stability of the tooling, making the clamping process more reliable.
[0048] When it is necessary to press the airbag to be processed, the airbag is located on the lower pressure plate 7. The piston rod of the cylinder 1 moves downward in the cylinder, driving the upper pressure plate 3 to move downward. The upper pressure plate 3 and the lower pressure plate 7 cooperate to press the airbag to be processed. By moving the piston rod up and down with the cylinder 1, the pressure acting on the airbag is controllable. The upper pressure plate 3 and the lower pressure plate 7 remain parallel, so that the pressure acting on the airbag is uniform, further improving the processing accuracy and quality of the airbag.
[0049] The crossbeam 9 and the column 10 are perpendicular to each other, providing stable support for the cylinder 1 and the lower pressure plate 7, ensuring the stability of the entire structure.
[0050] In some embodiments, such as Figure 4 As shown, the airbag clamping fixture also includes:
[0051] The stabilizing component 5 includes a bending rod 501 and a buffer 502. The buffer 502 is perpendicular to the lower pressure plate 7 and is embedded in the lower pressure plate 7. The bending rod 501 is located on the side of the lower pressure plate 7 near the upper pressure plate 3. The bending rod 501 is bent and the bend is at an angle. The airbag to be processed contacts the side of the bending rod 501 away from the lower pressure plate 7. The buffer 502 connects two inclined rods on the side near the lower pressure plate 7.
[0052] The stabilizing component 5 allows the airbag clamping fixture to better adapt to airbags of different shapes and sizes, reducing scratches or damage to the airbags and improving the fixture's versatility and safety. The buffer component 502 acts as a buffer, preventing the airbag from being damaged due to excessive pressure, ensuring the processing quality of the airbag, reducing friction between the bending rod 501 and the lower pressure plate 7, and improving the service life of the fixture.
[0053] The buffer element 502 includes a sliding bearing and an elastic element.
[0054] The bending rod 501, the sliding bearing, and the elastic element are connected sequentially from top to bottom.
[0055] The bending rod 501 is V-shaped, with an obtuse angle, forming a space to accommodate the airbag to be processed. A sliding bearing is installed on each side of the angle. An elastic element is installed below each sliding bearing.
[0056] When the airbag to be processed is pressed, the airbag is located on the bending rod 501. The upper pressure plate 3 presses down on the airbag and applies pressure to it. The pressure is transmitted to the elastic element through the bending rod 501 and the sliding bearing. The elastic element contracts, which plays a role in buffering and regulating the pressure.
[0057] When the shape or size of the airbag begins to change, the bending rod 501 deforms within a certain range to adapt to the changes in the airbag.
[0058] In some embodiments, the airbag clamping fixture further includes:
[0059] The support plate 8 is connected to the lower pressure plate 7 and is located on the side of the lower pressure plate 7 close to the upper pressure plate 3. During the process of the upper pressure plate 3 moving towards the lower pressure plate 7, the upper pressure plate 3 contacts the support plate 8.
[0060] The thickness of the support plate 8 can be set between 1mm and 20mm. The upper surface of the support plate 8 is higher than the upper surface of the lower pressure plate 7. The smaller the thickness of the support plate 8, the smaller the gap between the upper pressure plate 3 and the support plate 8 when they contact each other, and the smaller the volume of the airbag after processing. The larger the thickness of the support plate 8, the larger the gap between the upper pressure plate 3 and the support plate 8 when they contact each other, and the larger the volume of the airbag after processing.
[0061] The support plate 8 and the lower pressure plate 7 are fixed together by bolts, which makes it easy to replace the support plate 8 with one of different thicknesses according to different airbag volume requirements.
[0062] The upper pressure plate 3 moves downward to press the airbag until the lower surface of the upper pressure plate 3 contacts the upper surface of the support plate 8. By adjusting the thickness of the support plate 8, the airbag volume can be further controlled, the airbag processing quality can be improved, and various needs can be met.
[0063] In some embodiments, the airbag clamping fixture further includes:
[0064] The guide rail 4 is connected to the crossbeam 9 and the lower pressure plate 7 at both ends, and is parallel to the column 10. The upper pressure plate 3 is connected to the guide rail 4 and moves along the guide rail 4.
[0065] The guide rail 4 is connected to the crossbeam 9 and the lower pressure plate 7 at both ends, and is parallel to the column 10, providing guidance for the movement of the upper pressure plate 3. When the piston rod of the cylinder 1 drives the upper pressure plate 3 to move, the upper pressure plate 3 moves up and down along the guide rail 4. Due to the restriction of the guide rail 4, the upper pressure plate 3 can only move in the direction of the guide rail 4, ensuring the linearity and stability of the movement of the upper pressure plate 3.
[0066] The guide rail 4 improves the accuracy and stability of the upper pressure plate 3's movement, enabling it to accurately engage with the lower pressure plate 7 to press the airbag, reducing uneven airbag compression caused by deviations in the upper pressure plate 3's movement. Simultaneously, the guide rail 4 enhances the overall structural strength of the tooling, making it less prone to deformation during long-term use and extending its service life.
[0067] The guide rail 4 is connected to the column 10, which further improves the stability of the guide rail 4.
[0068] In some embodiments, the upper pressure plate 3 is provided with a protruding structure on the side near the guide rail 4, and the guide rail 4 includes a groove, with the protruding structure inserted into the groove.
[0069] A protruding structure on the side of the upper pressure plate 3 near the guide rail 4 is inserted into the groove of the guide rail 4, forming a sliding rail and slider mating structure. When the cylinder 1 drives the upper pressure plate 3 to move, the protruding structure slides in the groove. The groove further limits and guides the protruding structure, preventing the upper pressure plate 3 from shifting laterally during movement and ensuring that the upper pressure plate 3 moves accurately along the direction of the guide rail 4.
[0070] The combination of the raised structure and the groove further improves the accuracy and stability of the movement of the upper pressure plate 3. Compared with the simple guidance of the guide rail 4, this structure can better limit the lateral displacement of the upper pressure plate 3, ensuring that the airbag is subjected to uniform force during the pressing process. At the same time, this structure enhances the connection strength between the upper pressure plate 3 and the guide rail 4, improving the reliability and durability of the tooling.
[0071] In some embodiments, the airbag clamping fixture includes two guide rails 4, which are parallel to each other and are respectively connected to the two ends of the upper pressure plate 3. Both guide rails 4 are perpendicular to the upper pressure plate 3.
[0072] Two guide rails 4 are respectively connected to the two ends of the upper pressure plate 3, providing a stable guiding function for the movement of the upper pressure plate 3. The two ends of the upper pressure plate 3 can move up and down along the extension direction of the guide rails 4, further balancing the movement of the upper pressure plate 3.
[0073] In some embodiments, the airbag clamping fixture includes two cylinders 1, and the piston rods of the two cylinders 1 are respectively connected to the two ends of the upper pressure plate 3. The piston rods of the two cylinders 1 move simultaneously, driving the upper pressure plate 3 to move, further ensuring that the upper pressure plate 3 remains horizontal throughout the movement.
[0074] Two cylinders 1 are connected to the two ends of the upper pressure plate 3 respectively. When the two cylinders 1 run at the same time, their respective piston rods drive the two ends of the upper pressure plate 3 to move simultaneously, applying balanced power to the upper pressure plate 3 and pushing the upper pressure plate 3 to move up and down smoothly.
[0075] In some embodiments, the airbag clamping fixture further includes:
[0076] The control box 6 is connected to the column 10 and contains a built-in controller and a pressure regulating valve. The pressure regulating valve is connected to the cylinder 1.
[0077] The operator sets the required pressure parameters through the controller in the control box 6. The controller transmits the signal to the pressure regulating valve. The pressure regulating valve adjusts the gas pressure entering the cylinder 1 according to the signal, thereby controlling the extension and retraction force and speed of the piston rod of the cylinder 1, and realizing precise control of the airbag clamping force.
[0078] The control box 6, controller, and pressure regulating valve enable the airbag clamping fixture to precisely adjust the clamping force according to different processing requirements, improving the fixture's applicability. Compared to manual pressure adjustment, this automatic control method is more precise and stable, effectively ensuring the processing quality of the airbags while improving production efficiency.
[0079] The control box 6 can also set the clamping time, optimize manual timing, and reduce labor costs.
[0080] In the airbag clamping fixture, two columns 10 are installed on the side closer to the control box 6 to improve the overall stability of the fixture. On the side farther from the control box 6, one column 10 is installed for ease of operation.
[0081] In some embodiments, the airbag clamping fixture further includes:
[0082] Connector 2 is I-shaped, with one end connected to the piston rod and the other end connected to the upper pressure plate 3.
[0083] Connector 2 is I-shaped, with one end connected to the piston rod and the other end connected to the upper pressure plate 3, serving to connect and transmit force. When the piston rod of cylinder 1 extends or retracts, the force of the piston rod is transmitted to the upper pressure plate 3 through connector 2, causing the upper pressure plate 3 to move. The I-shaped structural design gives connector 2 good stability and strength during force transmission, and can evenly transmit the force of the piston rod to the upper pressure plate 3.
[0084] The design of connector 2 ensures the reliability and stability of the connection between the piston rod of cylinder 1 and the upper pressure plate 3, making the force transmission more uniform and efficient. The I-beam structure enhances the strength and rigidity of connector 2, enabling it to withstand greater pressure and tension, preventing damage or loosening of connector 2 during use, and improving the overall performance and service life of the tooling.
[0085] In some embodiments, the airbag clamping fixture also includes a grating and an operation button, both located on the lower pressure plate 7. The airbag to be processed can be clamped by operating the grating and the operation button, ensuring the safety of the clamping process.
[0086] In practical application, adhesive is applied to both ends of the airbag to be processed, and the airbag is placed on the lower pressure plate 7. The cylinder 1 drives the upper pressure plate 3 to move downward, pressing down the airbag until the lower surface of the upper pressure plate 3 contacts the upper surface of the support plate 8. The upper pressure plate 3 stops descending, and the control box 6 starts timing. The timing is 45 seconds. After the timing ends, the adhesive solidifies, and the cylinder 1 drives the upper pressure plate 3 to rise, completing the airbag compression.
[0087] Through the description of several embodiments of the airbag clamping fixture of this utility model, it can be seen that the embodiments of the airbag clamping fixture of this utility model have at least one or more of the following advantages:
[0088] 1. The upper pressure plate 3 is kept horizontal by the cylinder 1 and the guide rail 4 to evenly distribute the pressure on the airbag to be processed and avoid airbag leakage caused by uneven pressure.
[0089] 2. By changing the thickness of the support plate 8, the volume of the airbag to be processed can be adjusted to meet various volume requirements for airbags, thus expanding its applicability.
[0090] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0091] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
