Technical Field

[0001] This application relates to the field of air spring shaping technology, and in particular to an air spring support ring position shaping device. Background Technology

[0002] Currently, the automotive industry is widely promoting the use of air spring shock absorbers to replace traditional coil spring shock absorbers. Due to the unique structure of air springs, there is a process in the production of air springs where the support ring is installed into the inner hole of the bladder. The support ring is made of carbon steel with a large outer diameter, while the bladder is made of rubber with a small inner diameter and has an internal braided mesh. Under normal conditions, the diameter difference between the two is about 1.5 times. Current devices or structures that automatically install the support ring into the bladder have the problem of inaccurate installation position of the support ring. Therefore, there is an urgent need for a device or structure that can reshape the position of the support ring. Utility Model Content

Detailed Implementation

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does 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, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] like Figure 1 As shown, in this embodiment, an air spring support ring position shaping device is provided. This device includes a clamping mechanism 1 and a support ring mechanism 2. The clamping mechanism 1 is mainly used to position and clamp the air spring skin 5, and under the drive of the clamping mechanism 1, the air spring skin 5 can be driven to move along its axial direction. Here, the axial direction, as used below, refers to the axial direction of the air spring skin 5, which under certain conditions is in the same direction as the vertical direction; while the radial direction refers to the radial direction of the air spring skin 5, which under certain conditions is in the same direction as the horizontal direction.

[0056] Each clamping mechanism 1 includes an inner ring support 101 and an outer ring support 111 for clamping the bladder skin 5. Please refer to... Figure 4 The inner ring support 101 and the outer ring support 111 are located on the inner and outer rings of the bladder skin 5, respectively. After the relative displacement of the inner ring support 101 and the outer ring support 111, the inner ring support 101 and the outer ring support 111 can be sealed and pressed against the inner and outer rings of the bladder skin 5, respectively, so that the two clamping mechanisms 1 can be sealed and clamped at both ends of the axial direction of the bladder skin 5. It should be noted that the bladder skin 5 is a hollow rubber airbag, and the support ring 6 is located inside the hollow structure of the bladder skin 5.

[0057] Furthermore, a through hole 1013 structure is provided in the middle of the inner ring support member 101, through which the supporting ring mechanism 2 extends into the bladder skin 5; specifically, the number of supporting ring mechanisms 2 is the same as the number of clamping mechanisms 1, and they correspond one-to-one. After the supporting ring mechanism 2 extends into the corresponding through hole 1013, the outer wall of the supporting ring mechanism 2 can slide and seal with the hole wall of the through hole 1013, so that under the cooperation of the two supporting ring mechanisms 2 and the two through holes 1013 respectively, a sealed cavity structure is formed inside the bladder skin 5; and the supporting ring mechanism 2 includes an inflation member and a support member. The air outlet end of the inflation member is located at one end of the supporting ring mechanism 2 located in the sealed cavity and communicates with the sealed cavity. The air inlet end of the inflation member is located outside the sealed cavity, so as to inflate the sealed cavity and increase the outer diameter of the bladder skin 5.

[0058] The support member is also located at one end of the sealing cavity of the support ring mechanism 2, so the support member is also located inside the sealing cavity. The support member can be expanded or contracted radially. After the support member is expanded radially, it can abut against the inner ring of the support ring 6, thereby positioning the support member radially. In addition, the two support ring mechanisms 2 can move relative to each other in the axial direction. Therefore, under certain conditions, the two support members on the two support ring mechanisms 2 can clamp the support ring 6 in the axial direction, thereby positioning the support ring 6 axially and ensuring the positioning accuracy of the support ring 6.

[0059] Based on this, the clamping mechanism 1 and the supporting ring mechanism 2 can move relative to each other in the axial direction, so that the bladder skin 5 fixedly connected to the clamping mechanism 1 and the supporting ring 6 positioned and clamped by the supporting ring mechanism 2 can be displaced relative to each other in the axial direction, thereby adjusting the position of the supporting ring 6 relative to the bladder skin 5.

[0060] In summary, in this application, the two ends of the bladder skin 5 are respectively placed in two clamping mechanisms 1. The inner ring support 101 and the outer ring support 111 of the clamping mechanism 1 can seal and clamp the bladder skin 5, and the support ring mechanism 2 slides and seals with the through hole 1013 of the inner ring support 101, thereby forming a sealed cavity structure inside the bladder skin 5. The inflation component of the support ring mechanism 2 inflates the inside of the bladder skin 5, increasing the diameter of the bladder skin 5. The support ring 6 falls onto the support surface of the support ring mechanism 2. The support ring mechanism 2 positions the support ring 6 radially by unfolding the support component, and through the relative axial movement of the two support ring mechanisms 2, the support components of the two support ring mechanisms 2 clamp the support ring 6 axially and position the support ring 6 axially. Furthermore, the clamping mechanism 1 and the supporting ring mechanism 2 are axially movable relative to each other. Therefore, the clamping mechanism 1 can drive the bladder skin 5 to move relative to the supporting ring 6, and the two supporting ring mechanisms 2 can mechanically clamp the supporting ring 6, which can realize the stability of the supporting ring 6 during the position adjustment process, achieve the precise positioning of the supporting ring 6 in the bladder skin 5, and ensure the stability and quality of the finished product.

[0061] Please refer to Figure 4The inner ring support 101 includes a plate-shaped portion 1012 and a columnar portion 1011 disposed on the plate-shaped portion 1012. The through hole 1013 penetrates the plate-shaped portion 1012 and the columnar portion 1011. The outer ring support 111 includes a plurality of clamping blocks located on the outer periphery of the columnar portion 1011. The side of the clamping block facing the columnar portion 1011 is provided with an inner wall surface that matches the outer wall surface of the columnar portion 1011. The end of the bladder skin 5 is inserted between the outer wall surface of the columnar portion 1011 and the inner wall surface of the clamping block. The clamping block is fixedly disposed relative to the columnar portion 1011 in the axial direction and is movably disposed relative to the columnar portion 1011 in the radial direction. Thus, when the clamping block moves towards the columnar portion 1011, the inner wall surface of the clamping block and the outer wall surface of the columnar portion 1011 can be used to seal and clamp the bladder skin 5. Multiple clamping blocks are distributed on concentric circles with the axis of columnar part 1011 as the center, thus ensuring that multiple clamping blocks can be pressed synchronously on the outer periphery of the skin 5, ensuring that the skin 5 can be sealed and clamped at any point in the circumferential direction.

[0062] Each clamping mechanism 1 also includes a quick-change plate 115 and a pressure ring 103, please refer to Figure 2 and Figure 4 The quick-change plate 115 has a through hole in the middle. The plate-shaped part 1012 is fixedly installed on the quick-change plate 115, and the through hole 1013 corresponds to the position of the through hole of the quick-change plate 115, so as to ensure that the support ring mechanism 2 can be inserted into the bladder skin 5 through the through hole and the through hole 1013 in sequence. The pressure ring 103 is sleeved on the outer periphery of the clamping block. The side of the pressure block away from the columnar part 1011 has a first inclined surface, and the side of the pressure ring 103 facing the clamping block has a second inclined surface that cooperates with the first inclined surface. When the pressure ring 103 moves axially, the first inclined surface and the second inclined surface can contact and squeeze, thereby synchronously driving multiple pressure blocks to move towards the columnar part 1011, and after moving a certain distance, the pressure block and the columnar part 1011 seal and press the bladder skin 5.

[0063] The two clamping mechanisms 1 are distributed along the axial direction, please refer to... Figure 1 Here, the first clamping mechanism 1 is defined as the clamping mechanism 1 located on the axial lower side. A protective sleeve 102 is fixedly provided on the pressure ring 103 of this clamping mechanism 1. Please refer to... Figure 2 and Figure 5 The sleeve 102 provides a coarse guide for the bladder skin 5, making it easier for the bladder skin 5 to smoothly enter between the inner ring support 101 and the outer ring support 111.

[0064] In the first clamping mechanism 1, please refer to Figures 2 to 4The pressure ring 103 is connected to the clamping cylinder mounting plate 105 via two first guide shafts 104. The locking pin 106 allows for quick replacement of the pressure ring 103 and the first guide shafts 104 to adapt to different products. The first guide shaft 104 can slide up and down within the first linear bearing 107, which is fixed on the first fixed seat 108. The clamping cylinder 109 is fixed on the first fixed seat 108 and connected to the clamping cylinder mounting plate 105 via the first floating joint 110.

[0065] The clamping cylinder 109 extends and drives the pressure ring 103 to move downward through the first guide shaft 104. The pressure ring 103 drives the clamping block to move towards the middle through the second inclined surface. The clamping block is fixed on the linear guide rail 112, thereby ensuring that each clamping block can move stably along the linear guide rail 112 and clamp the lower end face of the bladder skin 5.

[0066] A return spring 113 is provided between the clamping block and the columnar part 1011. The return spring 113 is used to provide the clamping block with an elastic force away from the columnar part 1011. The two ends of the return spring 113 can be set in the pin holes opened on the clamping block and the columnar part 1011 to ensure that the size of the return spring 113 itself will not affect the clamping effect of the clamping block and the columnar part 1011 on the skin 5.

[0067] The protective cover 114 protects the linear guide rail 112. The inner ring support 101, the protective cover 114 and the linear guide rail 112 are fixed on the quick-change plate 115. The quick-change plate 115 is equipped with handles 116 on both sides. The quick-change plate 115 and all the parts installed on it are quick-change fixtures, which can be quickly positioned by the first positioning sleeve 117, the first positioning pin 118 and the second positioning pin 119.

[0068] A pressure plate 120 is provided on the quick-change plate 115. The pressure plate 120 can be locked under the limiting action of the screw 121, thereby fixing the quick-change plate 115 to the positioning plate 122 by the screw 121. The positioning plate 122 has a sensor mounting plate 123. Multiple proximity sensors 124 are installed on the sensor mounting plate 123. The proximity sensors 124 detect the model of the detection screw 125 on the quick-change plate 115, thereby confirming the model of the tooling on the current quick-change plate 115, and thus confirming the specifications of the bladder 5 and the support ring 6 on the current quick-change plate 115.

[0069] The positioning plate 122 is fixed on both sides of the end of the support shaft 126. The first fixing seat 108 is set on both sides of the support shaft 126 and fixed by the first locking nut 127. The end of the support shaft 126 away from the positioning plate 122 is fixed with the first guide shaft support 128.

[0070] The inner wall of the columnar part 1011 is provided with a first sealing ring 129, and the outer wall of the support ring mechanism 2 slides and seals with the first sealing ring 129; the inner wall of the clamping block or the outer wall of the columnar part 1011 is embedded with a second sealing ring 130, and the second sealing ring 130 seals and abuts against the bladder skin 5.

[0071] Here, the second clamping mechanism 1 is defined as the clamping mechanism 1 located on the axial upper side. The second clamping mechanism 1 has the same structural principle as the first clamping mechanism 1. In the second clamping mechanism 1, please refer to... Figure 8 and Figure 9 The clamping cylinder 109 is fixed to the quick-change plate 115 by a pad. The clamping cylinder 109 is connected to the pressure ring 103 through the first floating joint 110. When the clamping cylinder 109 retracts, it drives the pressure ring 103 to move upward. The pressure ring 103 drives the clamping block to move towards the middle through the second inclined surface. The clamping block is fixed on the linear guide rail 112, thereby clamping the upper end face of the bladder skin 5. The clamping block can be reset by the return spring 113. The quick-change plate 115 is equipped with handles 116 on both sides. The quick-change plate 115 and all the parts installed on it are quick-change fixtures, which can be quickly positioned by the first positioning sleeve 117, the first positioning pin 118, and the second positioning pin 119.

[0072] Since the two ring support mechanisms 2 have the same structure, they will not be described separately here; each ring support mechanism 2 also includes a fixed shaft 211, please refer to Figure 6 and Figure 7 The outer wall surface of the fixed shaft 211 can slide and seal with the through hole 1013, and the support is located at one end of the fixed shaft 211 located in the sealing cavity, and the fixed shaft 211 has an axial hollow cavity inside.

A spacer 208 is provided between the two bearings and sleeved on the outer circumference of the venting drive shaft 205. The spacer 208 is fixed by a second locking nut 209.

[0074] Above the double-row angular contact ball bearing 206 is a pressure cap 210. The double-row angular contact ball bearing 206 and the deep groove ball bearing 207 are mounted on the fixed shaft 211. Under the action of the two bearings, an annular gap 227 is formed between the venting drive shaft 205 and the cavity wall of the hollow cavity. The two ends of the annular gap 227 are sealed. The fixed shaft 211 is provided with an air inlet channel 226 that communicates with the annular gap 227. The venting drive shaft 205 is provided with an air outlet channel 228 that communicates with the annular gap 227.
