[0002] As a core component of a vehicle's passive safety system, the assembly precision of the airbag frame directly affects the reliability and timeliness of airbag deployment. In traditional production processes, the positioning and clamping of airbag frames mainly relies on manual handling combined with simple tooling.
[0003] However, the metal frame of the airbag needs to be repeatedly adjusted to meet the requirements of the welding / assembly station. Manual adjustment is time-consuming and labor-intensive, resulting in low assembly efficiency. Utility Model Content
[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an automotive airbag frame clamping fixture, which solves the problem of low efficiency in the assembly process of manually handling and adjusting the airbag frame in the prior art.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an automotive airbag frame clamping fixture, comprising: a support column fixed on a base; a lifting column disposed within the support column, the lifting column being capable of rising and falling relative to the support column; a bearing portion rotatably disposed on the side of the lifting column; an operating column slidably disposed within the bearing portion, the operating column rotating relative to the bearing portion; and a support plate fixed to one end of the operating column, the support plate being rotatably provided with a clamp.
[0006] Optionally, the lifting column includes a connecting part and a lifting part. The lifting part includes two sealing plates distributed vertically and multiple side plates disposed between the two sealing plates. The support column is hollow inside. Multiple sealing plate openings are opened at the end of the support column away from the base. The side plates are slidably connected to the sealing plate openings.
[0007] Optionally, a lead screw is rotatably connected inside the support column, a first bevel gear is fixed on the lead screw, and a second bevel gear that meshes with the first bevel gear is rotatably provided inside the support column. The second bevel gear is driven by a motor fixed on the support column, and one of the sealing plates is threadedly connected to the lead screw.
[0008] Optionally, the bearing is connected to the connecting part by a bearing. The bearing has a ring-shaped structure, and a rotating block is connected to its inner ring diameter by a bearing. The rotating block has a ring opening, and the operating column is inserted into the ring opening.
[0009] Optionally, the annular opening has multiple notches, and the operating column is fixed with a side strip at the position corresponding to the notch. The side strip has a number of limiting holes, and at least two of the limiting holes are internally threaded with a first threaded pin.
[0010] Optionally, the connecting part is provided with a pin hole, a limiting pin is inserted into the pin hole, and an abutment block is fixed on the bearing part to cooperate with the limiting pin.
[0011] Optionally, a ball seat is fixed on the support plate, and a rotating ball is rotatably disposed inside the ball seat, the rotating ball being fixed on the clamp.
[0012] Optionally, the support plate is threaded with a plurality of second threaded pins, and a push ball is fixed to the side of the second threaded pins near the clamp, the push ball abutting against the clamp.
[0013] Optionally, the base is provided with multiple casters.
[0014] Optionally, a handle is fixed to the end of the operating column away from the support plate.
[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model integrates a lifting column inside the support column. It uses a motor to drive the second bevel gear to mesh with the first bevel gear, thereby driving the lead screw to rotate, realizing the linear lifting motion of the lifting column relative to the support column, and meeting the height positioning requirements of the airbag frame in the vertical direction (Z axis).
[0017] Meanwhile, the bearing portion located on the side of the lifting column in this invention, through its bearing connection structure, can rotate 360° steplessly relative to the lifting column. This design allows the horizontal orientation (rotation angle around the Z-axis) of the fixture installed at the end to be freely adjusted according to the workstation requirements, significantly enhancing the adaptability of the fixture.
[0018] Furthermore, in this invention, the operating column is slidably disposed within the annular opening of the bearing portion, and axial displacement is achieved through the cooperation of the edge strip and the notch. This structure allows the clamp to be extended and retracted in the horizontal direction (X / Y plane) to adapt to different size or positional requirements. After adjustment, the operating column can be reliably locked within the bearing portion by screwing the first threaded pin into the selected limiting hole, ensuring stable positioning.
[0019] Finally, the clamp of this invention can be rotated relative to the support plate by means of the cooperation between the rotating ball and the ball seat. This allows the clamp to precisely match complex assembly or welding angles. After adjustment, by tightening the multiple second threaded pins on the support plate, the clamp's posture can be firmly locked by using the push balls at their ends to press against the clamp.
[0020] In summary, the clamping fixture provided by this utility model solves the problems of low efficiency and insufficient precision of traditional manual handling and adjustment, and greatly improves the ease of operation, positioning accuracy and overall assembly efficiency of the airbag frame in the assembly line flow, positioning and final assembly process.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] As mentioned earlier, the posture of the car's airbag frame is repeatedly adjusted during the production and assembly process to meet the requirements of the welding / assembly station. Manual adjustment is time-consuming and labor-intensive, resulting in low assembly efficiency.
[0039] To address this issue, this utility model provides a clamping fixture applied in the production and assembly of automotive airbag frames. Through corresponding components, it achieves omnidirectional free adjustment and locking of the frame clamping, thereby solving the aforementioned problems. This utility model solves the problem in the following way.
[0040] Example 1:
[0041] Please refer to the instruction manual appendix. Figures 1 to 4 As shown in the figure, this embodiment provides an automotive airbag frame clamping fixture, which includes a base 1, a support column 2, a lifting column 3, a bearing 4, an operating column 5, a support plate 6, and a clamp 7.
[0042] The base 1 has several casters at its bottom. A support column 2 is fixed to the base 1. The support column 2 is hollow, and a partition is fixed to its hollow portion. This partition faces the base 1 (bottom), dividing the hollow portion of the support column 2 into an upward-facing first chamber and a downward-facing second chamber. A lead screw 22 is rotatably connected inside the support column 2. The lead screw 22 passes through the partition and connects the first and second chambers. Within the second chamber, a first bevel gear 23 is fixed to the lead screw 22. A second bevel gear 24 meshes with the first bevel gear 23 and is rotatably connected within the second chamber. Simultaneously, a motor box is fixed to the outside of the support column 2 at a position corresponding to the second chamber. A motor 25 is fixed inside the motor box. The output shaft of the motor 25 passes through the motor box and the support column 2, extends into the second chamber, and connects to the second bevel gear 24. Therefore, when the output shaft of the motor 25 rotates, the second bevel gear 24 rotates accordingly, thereby meshing with the first bevel gear 23 and rotating, ultimately driving the lead screw 22 to rotate.
[0043] In this first embodiment, as Figure 3 As shown, the support column 2 has four sealing plate openings 21 along its four sides at the end furthest from the base 1 (top). The lifting column 3 includes a connecting part 31 and a lifting part 32. The connecting part 31 is fixed to the top of the lifting part 32 and is also sleeved on the top of the support column 2. When the distance between the lifting column 3 and the support column 2 is minimal, the connecting part 31 abuts against the top of the lifting column 3. The lifting part 32 includes two vertically distributed sealing plates 322 and four side plates 321 disposed between the two sealing plates 322. The uppermost sealing plate 322 is located outside the support column 2, and the lowermost sealing plate 322 is located inside the first cavity of the support column 2. At the same time, the lowermost sealing plate 322 has four small holes, each of which is equipped with a guide post (a total of four). These four guide posts are fixed in the first cavity, so that the lowermost sealing plate 322 is guided and limited by these four guide posts when it moves up and down. The bottom sealing plate 322 has a threaded opening in the middle, and is threaded to the lead screw 22 through this threaded opening. Therefore, when the lead screw 22 rotates, the sealing plate 322 moves along the lead screw 22 due to the influence of the threaded connection, thereby realizing the lifting and lowering.
[0044] Meanwhile, the four side plates 321 are inserted into the sealing plate opening 21 and can slide within the sealing plate opening 21. When the lowest sealing plate 322 abuts against the top of the support column 2, the lifting column 3 rises to its highest position, and when the lowest sealing plate 322 abuts against the top of the support column 2, the lifting column 3 descends to its lowest position.
[0045] Example 2:
[0046] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 1 to 2 , Figures 5 to 6 As shown in this second embodiment, a protruding column is fixed to the middle of one side of the connecting part 31. This column is connected to the bearing part 4 via a bearing. Two pin holes 311 are provided on the connecting part 31, and a limiting pin 312 is inserted into each pin hole 311. Correspondingly, two abutment blocks 42 are fixed to both sides of the bearing part 4. Each abutment block 42 has a downward-facing opening (on the base 1 side), and the limiting pin 312 abuts against this opening, thereby limiting the rotation of the bearing part 4. When the bearing part 4 needs to rotate, the limiting pin 312 can be removed.
[0047] In this second embodiment, as Figure 5 , Figure 6 As shown, the bearing 4 has a ring-shaped structure, and a rotating block 41 is connected to its inner ring diameter via a bearing. The rotating block 41 has an annular opening 411, and two notches 412 communicating with it are formed along the annular opening 411. Simultaneously, the operating column 5 is inserted into the annular opening 411. Figure 5 As shown, a side strip 51 is fixed at the position of the operating column 5 corresponding to the notch 412, and the side strip 51 has several limiting holes 511. At least two of the limiting holes 511 are internally threaded with first threaded pins 52. When the operating column 5 (the end of the operating column 5 away from the support plate 6 is fixed with a handle, which is used to operate the operating column 5) is moved relative to the bearing part 4 to the designated position, the aforementioned two (or more) first threaded pins 52 are threadedly connected to the threaded openings on both sides of the rotating block 41 to achieve a locking engagement, thereby limiting the sliding distance of the operating column 5.
[0048] Example 3:
[0049] Based on the above embodiments, in order to further clarify and completely explain the technical features therein, this utility model also provides Embodiment Three. For example... Figures 1 to 2 , Figure 7 As shown, in this third embodiment, the support plate 6 is fixed to the end of the operating column 5 away from its handle, and a ball seat 63 is fixed on the support plate 6. A rotating ball 71 is rotatably arranged inside the ball seat 63. The rotating ball 71 is fixed on the clamp 7, so that the clamp 7 can be adjusted in orientation relative to the support plate 6.
[0050] The support plate 6 is threaded with multiple second threaded pins 61. A push ball 62 is fixed to the side of the second threaded pin 61 near the clamp 7, and the push ball 62 abuts against the clamp 7. By adjusting the distance between the push ball 62 and the clamp 7, the orientation angle of the clamp 7 is limited, thereby meeting the different orientation requirements of the airbag frame clamped on it.
[0051] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to:
[0052] This utility model integrates a lifting column 3 inside the support column 2. The motor 25 drives the second bevel gear 24 to mesh with the first bevel gear 23, thereby driving the lead screw 22 to rotate, realizing the linear lifting motion of the lifting column 3 relative to the support column 2, and meeting the height positioning requirements of the airbag frame in the vertical direction (Z axis).
[0053] Meanwhile, the bearing portion 4 located on the side of the lifting column 3 in this invention, through its bearing connection structure, can rotate 360° steplessly relative to the lifting column 3. This design allows the horizontal orientation (rotation angle around the Z-axis) of the fixture 7 installed at the end to be freely adjusted according to the workstation requirements, significantly enhancing the adaptability of the fixture.
[0054] Furthermore, in this invention, the operating column 5 is slidably disposed within the annular opening 411 of the bearing portion 4, and axial displacement is achieved through the cooperation of the edge strip 51 and the notch 412. This structure allows the clamp 7 to be extended and retracted in the horizontal direction (X / Y plane) to adapt to different size or positional requirements. After adjustment, the operating column 5 is reliably locked within the bearing portion 4 by screwing the first threaded pin 52 into the selected limiting hole 511, ensuring stable positioning.
[0055] Finally, the clamp 7 of this invention can be rotated relative to the support plate 6 by means of the cooperation between the rotating ball 71 and the ball seat 63. This allows the clamp 7 to precisely match complex assembly or welding angles. After adjustment, by tightening the multiple second threaded pins 61 on the support plate 6, the clamp 7 can be firmly locked in position by using the push ball 62 at its end to press against it.
[0056] In summary, the clamping fixture provided by this utility model solves the problems of low efficiency and insufficient precision of traditional manual handling and adjustment, and greatly improves the ease of operation, positioning accuracy and overall assembly efficiency of the airbag frame in the assembly line flow, positioning and final assembly process.
[0057] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
