For this reason, the air suspension system came into being. It uses air springs as elastic elements and uses the compressibility of gas to achieve elastic effect. The air pressure of the compressed gas can be automatically adjusted with changes in load and road conditions, thereby improving riding comfort. When the related technology is to buckle the end of the air spring, it is necessary to place the buckling ring in the through hole on the turntable, and pass the bladder skin through the buckling ring, and then install the sealing plate on the end of the bladder skin, and finally buckle the buckling ring on the end of the bladder skin through the buckling unit on the turntable.

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 8As shown, the sealing plate crimping tool for air springs of the present invention comprises a frame 1 and a processing table 11, a fixing plate 12 is provided on the processing table 11, the fixing plate 12 has a through hole 121, a crimping assembly for crimping a buckle 42 on the outside of a bladder skin 41 is provided in the through hole 121, the crimping assembly comprises a plurality of crimping parts 13 uniformly arranged along the circumference of the through hole 121, and the plurality of crimping parts 13 can be synchronously moved inward or outward along the radial direction of the through hole 121, a socketing mechanism is also provided on the processing table 11, and the socketing mechanism comprises an adjusting assembly and a driving assembly.

[0037] Specifically, when it is necessary to buckle the sealing plate 43 of the air spring, the buckle ring 42 is placed in the through hole 121 and clamped by a plurality of buckling parts 13. Then, the bladder skin 41 is passed through the middle of the buckle ring 42 so that the buckle ring 42 is sleeved on the outside of the bladder skin 41. Then, the sealing plate 43 is inserted into the end of the bladder skin 41, and the position of the bladder skin 41 is adjusted so that the sealing plate 43 is aligned with the buckle ring 42. The buckle ring 42 is buckled on the outside of the bladder skin 41 through the synchronous inward movement of a plurality of buckling parts 13, and the sealing plate 43 is locked and fixed to achieve the sealing of the air spring.

[0038] The adjusting assembly includes a moving ring 21, an inner rod 22 and an outer rod 23. The moving ring 21 can move along the length direction of the processing table 11. The inner rod 22 and the outer rod 23 are both set to at least three. The multiple inner rods 22 and the multiple outer rods 23 are evenly and alternately arranged along the circumference of the moving ring 21, and one end away from the moving ring 21 extends toward the fixed plate 12. The driving assembly includes a driving member 1 for driving the inner rod 22 or the outer rod 23 to move along the radial direction of the moving ring 21, and a driving member 2 for adjusting the inclination angle of the inner rod 22 or the outer rod 23, so that the inner rod 22 and the outer rod 23 It has three states: State 1, the inner rod 22 is arranged horizontally, and the outer rod 23 gradually tilts outward along the axis of the moving ring 21 toward the direction close to the fixed plate 12, so that the end of the bag skin 41 can be stuck between the inner rod 22 and the outer rod 23; State 2, the inner rod 22 and the outer rod 23 are gradually tilted outward along the axis of the moving ring 21 toward the direction close to the fixed plate 12, which is used to squeeze the end of the bag skin 41 into a contracted state; State 3, the inner rod 22 and the outer rod 23 are gradually tilted inward along the axis of the moving ring 21 toward the direction close to the fixed plate 12, which is used to stretch the end of the bag skin 41 into an expanded state.

[0039] Specifically, Figures 1 to 7As shown, the inner rod 22 and the outer rod 23 present three states. In the first state, the inner rod 22 is horizontally arranged, and the outer rod 23 gradually tilts outward along the axis of the moving ring 21 toward the fixed plate 12. At this time, the bag skin 41 is pushed in the direction close to the fixed plate 12, and the end of the bag skin 41 can be pushed between the inner rod 22 and the outer rod 23. In the second state, the inner rod 22 and the outer rod 23 are driven by the driving member 1 to move along the radial direction of the moving ring 21 toward the axis of the moving ring 21, and at the same time, the inner rod 22 is driven by the driving member 2 to change the inclination angle, so that the inner rod 22 and the outer rod 23 are gradually tilted outward along the axis of the moving ring 21 toward the fixed plate 12. In this process, the end of the bag skin 41 stuck between the inner rod 22 and the outer rod 23 can be squeezed into a contracted state through the movement of the inner rod 22 and the outer rod 23. At this time, the size of the end of the bag skin 41 is smaller than the inner diameter of the buckle 42, which is convenient for the bag skin 41 to pass through the middle of the buckle 42. In the three states, the inner rod 22 and the outer rod 23 are driven by the first driving member to move in the radial direction of the moving ring 21 in the direction away from the axis of the moving ring 21, and at the same time, the inner rod 22 and the outer rod 23 are driven by the second driving member to change the inclination angle, so that the inner rod 22 and the outer rod 23 are gradually inclined inward along the axis of the moving ring 21 toward the fixed plate 12. In this process, the capsule 41 inserted between the inner rod 22 and the outer rod 23 can be moved by the movement of the inner rod 22 and the outer rod 23. The end is stretched out and in an expanded state. At this time, the size of the end of the bladder skin 41 is larger than the outer diameter of the sealing plate 43, which makes it easy to insert the sealing plate 43 into the end of the bladder skin 41. Then, by moving the movable ring 21, the inner rod 22 and the outer rod 23 are driven to separate from the bladder skin 41. At this time, the end of the bladder skin 41 will return to its initial state and wrap around the outside of the sealing plate 43. Then, by moving the buckling piece 13, the buckling ring 42 is buckled on the outside of the sealing plate 43 to complete the buckling process of the sealing plate 43 of the air spring.

[0040] In some embodiments, a guide groove 231 is provided on the outer rod 23 along its axial direction, and a hook rod 232 is provided in the guide groove 231. The hook rod 232 is L-shaped, and one end is slidably provided in the guide groove 231, and the other end extends in the direction away from the movable ring 21. When the bag skin 41 is pushed between the inner rod 22 and the outer rod 23, the end of the bag skin 41 will be stuck between the outer rod 23 and the hook rod 232.

[0041] Specifically, Figures 3 to 7 As shown, when the bag skin 41 is pushed between the inner rod 22 and the outer rod 23, the end of the bag skin 41 will be stuck between the outer rod 23 and the hook rod 232. At this time, when the outer rod 23 is driven to move along the radial direction of the movable ring 21 by the driving member, the end of the bag skin 41 stuck between the outer rod 23 and the hook rod 232 can be driven to move synchronously, so as to squeeze the end of the bag skin 41 into a contracted state, or stretch it into an expanded state.

[0042] In some embodiments, two clamping plates 24 are further provided on the fixing plate 12 . The two clamping plates 24 are horizontally slidably arranged on the fixing plate 12 along the radial direction of the through hole 121 , and the two clamping plates 24 can synchronously approach or move away from each other along the radial direction of the fixing plate 12 .

[0043] Specifically, Figures 1 to 3 As shown, when the inner rod 22 and the outer rod 23 are in the third state, the end of the bladder skin 41 can be stretched open to an expanded state. At this time, the size of the end of the bladder skin 41 is larger than the outer diameter of the sealing plate 43, which is convenient for inserting the sealing plate 43 into the end of the bladder skin 41. Then, through the movement of the movable ring 21, the bladder skin 41 and the sealing plate 43 inserted into the bladder skin 41 are driven to move synchronously. When the sealing plate 43 moves to the fixed plate 12, the two clamping plates 24 approach each other to clamp the bladder skin 41 on the outside of the sealing plate 43. At this time, the movable ring 21 moves away from the fixed plate 12. The movement can drive the inner rod 22 and the outer rod 23 to gradually separate from the bag skin 41. During this process, the clamping plate 24 is provided to clamp the bag skin 41 on the outside of the sealing plate 43, so that the sealing plate 43 will not be separated from the bag skin 41 during the process of the inner rod 22 and the outer rod 23 being pulled out. After the inner rod 22 and the outer rod 23 are pulled out, the end of the bag skin 41 returns to its initial state and is tightly wrapped around the outside of the sealing plate 43. Then, the buckle 42 is buckled onto the outside of the sealing plate 43 through the buckling assembly, so that the bag skin 41, the buckle 42 and the sealing plate 43 can be tightly assembled.

[0044] In some embodiments, the driving member 1 is a telescopic rod 25, and the telescopic rod 25 is provided in plurality and corresponds one-to-one with the plurality of inner rods 22 and the plurality of outer rods 23 respectively. Each telescopic rod 25 is arranged along the radial direction of the moving ring 21, and one end is connected to the moving ring 21, and the other end is hinged to the corresponding inner rod 22 or outer rod 23. One end of the inner rod 22 and the outer rod 23 facing the moving ring 21 passes through the moving ring 21 to extend to the other side by a set length. The driving member 2 is a telescopic rod 26, and the telescopic rod 26 is provided in plurality and corresponds one-to-one with the plurality of inner rods 22 and the plurality of outer rods 23 respectively. One end of each telescopic rod 26 is hinged to the middle part of the corresponding telescopic rod 25, and the other end is hinged to the end of the corresponding inner rod 22 or outer rod 23 close to the moving ring 21.

[0045] Specifically, Figures 3 to 7As shown, multiple telescopic rods 1 25 corresponding to the inner rod 22 are connected to the electric control structure 1, so that through the electric control structure 1, the multiple telescopic rods 1 25 corresponding to the inner rod 22 can be controlled to be telescopic, and the multiple inner rods 22 are driven to move synchronously along the radial direction of the moving ring 21. Similarly, multiple telescopic rods 1 25 corresponding to the outer rod 23 are connected to the electric control structure 2, which can drive the multiple outer rods 23 to move synchronously along the radial direction of the moving ring 21; multiple telescopic rods 26 corresponding to the inner rod 22 are connected to the electric control structure 3, so that through the electric control structure 3, the multiple telescopic rods 26 corresponding to the inner rod 22 can be controlled to be telescopic, so that the length of the telescopic rods 26 changes, and the inner rod 22 is driven to flip around the hinge point with the telescopic rod 1 25, so that the inclination angles of the multiple inner rods 22 change synchronously. Similarly, multiple telescopic rods 26 corresponding to the outer rod 23 are connected to the electric control structure 4, so as to drive the multiple outer rods 23 to change their inclination angles synchronously.

[0046] In some embodiments, the processing table 11 is also provided with a clamping assembly for clamping the bag skin 41, and the clamping assembly includes a movable seat 31, two clamping plates 32 arranged on the movable seat 31, and a driving rod 33 for driving the two clamping plates 32 to move closer to or away from each other. The movable seat 31 can move along the length direction of the processing table 11, and a slide groove 111 is provided on the processing table 11 along its length direction. The movable ring 21 and the movable seat 31 are both slidably matched with the processing table 11 through the slide groove 111.

[0047] Specifically, Figure 1 , Figure 2 and Figure 8 As shown, by driving the two clamping plates 32 to approach each other through the driving rod 33, the bag skin 41 located at the upper end of the movable seat 31 can be clamped to prevent the bag skin 41 from shaking during the buckling process and affecting the buckling quality. At this time, the movement of the movable seat 31 can drive the clamped bag skin 41 to move synchronously, so that the bag skin 41 moves toward the direction close to the fixed plate 12.

[0048] In some embodiments, rollers 34 are provided on the upper end of the movable seat 31 and on the opposite side of the two clamping plates 32. Specifically, Figure 2 and Figure 8As shown, by the mutual approach of the two clamping plates 32, the bag skin 41 located at the upper end of the movable seat 31 can be clamped to prevent the bag skin 41 from shaking during the buckling process. After the end of the bag skin 41 is clamped into the inner rod 22 and the outer rod 23, the end of the bag skin 41 will be squeezed into a contracted state during the process of driving the inner rod 22 and the outer rod 23 to the second state through the driving component. At this time, the inner rod 22 and the outer rod 23 are driven by the movable ring 21 to move away from the fixed plate 12, which can drive the bag skin 41 stuck between the inner rod 22 and the outer rod 23 to move synchronously, so that the bag skin 41 passes through the middle of the buckle 42, thereby reducing the friction between the bag skin 41 and the movable seat 31 and the clamping plate 32, and realizing the smooth movement of the bag skin 41.

[0049] like Figure 2 and Figure 8 As shown, the movable seat 31 is a telescopic structure, so as to adjust the height of the movable seat 31 and the two clamping plates 32, so as to be able to clamp the bladder skins 41 of different diameters, so that the axis of the bladder skin 41 is consistent with the axis of the through hole 121, thereby improving the applicability of the device.
