During the use of the electronic cigarette, in order to avoid the leakage of e-liquid or smoke, sealing rings need to be provided on components such as the atomizer assembly. When assembling the sealing rings, most are assembled manually, so the efficiency is low; or, when some assembling devices are used for assembling the sealing rings, only one sealing ring can be assembled at a time, resulting in low working efficiency. Content of the Utility Model

[0015] The first end of the first rotating part is rotatably connected to the frame, and the second end is rotatably connected to the first end of the second rotating part. The lifting robotic arm is vertically movable along the C direction and is connected to the second end of the second rotating part.

[0016] Alternatively, the first end of the first rotating part is movably connected to the frame along the X direction. The first end of the second rotating part is telescopically connected to the second end of the first rotating part. The lifting robotic arm is vertically movable along the C direction and is connected to the second end of the second rotating part.

[0017] As a further technical solution, the conveying mechanism includes a conveying track and a carrier. The conveying track is arranged on the upper end face of the frame and extends along the A direction. The carrier is slidably connected to the conveying track, and a plurality of workstations for placing the workpieces are arranged on the carrier.

[0018] As a further technical solution, the conveying track and the ring support device are arranged at a relative interval along the X direction.

[0019] As a further technical solution, the object picking assembly includes a connecting piece, an inner sleeve, an outer sleeve and an elastic member. The inner sleeve, the outer sleeve and the elastic member are all provided in multiple groups corresponding to the ring support mechanism.

[0020] The outer sleeve is sleeved on the outer periphery of the corresponding inner sleeve. One end of the elastic member is connected to the first end of the inner sleeve, and the other end is connected to the outer sleeve or the connecting piece.

[0021] At least a part of the second end of the inner sleeve extends out of the end of the outer sleeve away from the connecting piece.

[0022] The inner sleeve is configured to move relative to the outer sleeve under external actuation.

[0023] As a further technical solution, the inner sleeve and the outer sleeve are coaxially arranged.

[0024] One end of the outer sleeve close to the connecting piece is provided with a communication hole, and the inner sleeve is connected to the connecting piece through the elastic piece passing through the communication hole.

[0029] Compared with the prior art, the technical advantages of the sealing ring assembly equipment provided by the present utility model are as follows:

[0030] 1. Since the first driving assembly operates to drive the ring support mechanism to open, thereby expanding the sealing ring arranged on the ring support mechanism; therefore, when sleeving the sealing ring, the speed of expanding the sealing ring can be increased, and the expansion amount of all the sealing rings passing through the ring support mechanism can be ensured to be consistent. Since there are multiple groups of ring support mechanisms, the multiple groups of ring support mechanisms open simultaneously, so that multiple sealing rings are expanded simultaneously, thereby further improving the overall processing efficiency.

[0031] 2. When assembling the sealing ring and the target workpiece, the process is as follows: the ring support device first expands multiple sealing rings, then multiple material taking mechanisms respectively pick up the corresponding expanded sealing rings, and then assemble the expanded sealing rings with the corresponding workpieces placed on the conveying mechanism. In addition, since the ring support device and the material taking mechanism are relatively independent, when multiple material taking structures respectively pick up the corresponding expanded sealing rings and assemble the expanded sealing rings with the corresponding workpieces, the ring support device can synchronously perform the expansion work of the next batch of sealing rings. When the material taking mechanism completes the assembly of the expanded sealing rings of the current batch with the corresponding workpieces, it can immediately pick up the expanded sealing rings of the next batch without reserving expansion time for the ring support device, thereby further improving the assembly efficiency.

[0051] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the convenience of description, only parts related to the present utility model are shown in the drawings, rather than all the structures.

[0052] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to" and "fixed" shall be understood in a broad sense.

[0053] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0055] Combination Figures 1 to 9 As shown, the sealing ring assembly equipment provided in this embodiment is used to complete the assembly of the sealing ring 10 and the corresponding target workpiece 20, so as to reduce the processing cost and improve the processing efficiency. Specifically, the sealing ring assembly equipment includes a frame 100, a support ring device and a feeding device 400; the support ring device is installed on the upper end surface of the frame 100, and the support ring device includes a first drive assembly 200 and a plurality of support ring mechanisms 300. The first output shaft of the first drive assembly 200 is connected to a driving rack 210, and each group of support ring mechanisms 300 includes a transmission gear 310 and a support ring assembly 320 connected to the transmission gear 310, and each transmission gear 310 is meshed with the driving rack 210; the feeding device 400 is installed on the frame 100. The upper end surface of the feeding device 400 includes a picking mechanism 410 and a conveying mechanism 420. The picking mechanism 410 is provided with a plurality of picking components 412 corresponding to the support ring mechanism 300. The conveying mechanism 420 is used to accommodate the workpiece 20. When the first driving component 200 drives the driving rack 210 to move along the A direction, it can drive the corresponding support ring component 320 to open through the transmission gear 310 to open the sealing ring 10 placed on the support ring component 320. The plurality of picking components 412 can take the opened sealing ring 10 and assemble it with the corresponding workpiece 20.

[0056] Since the first driving component 200 operates, the support ring component 320 is driven to open, thereby expanding the sealing ring 10 placed on the support ring component 320; therefore, when the sealing ring 10 is installed, not only the speed of expanding the sealing ring 10 can be increased, but also the opening degree of the support ring component 320 can be changed by setting the output value of the first driving component 200 to ensure that the expansion amount of all the sealing rings 10 passing through the support ring component 320 is consistent, thereby avoiding the occurrence of situations such as the sealing ring 10 breaking due to manual differences or the abnormality of the assembled parts due to improper operation, thereby improving the installation effect of the sealing ring 10 on the workpiece 20 and reducing the probability of the sealing ring 10 being damaged during the support ring assembly stage, thereby reducing production costs.

[0057] Since multiple groups of support ring assemblies 320 are provided, and each group of support ring assemblies 320 is meshed with the driving rack 210 through the corresponding transmission gear 310; therefore, when the first driving assembly 200 drives the driving rack 210 to move along the A direction, the driving rack 210 can be meshed with multiple transmission gears 310 to drive multiple groups of support ring assemblies 320 to open at the same time, thereby achieving multiple sealing rings 10 being stretched at the same time, so as to further improve the overall processing efficiency.

[0058] When the sealing ring 10 and the target workpiece 20 are assembled, the process is that the ring-supporting device first expands the plurality of sealing rings 10, and then the plurality of material-taking structures respectively take the corresponding expanded sealing rings 10, and then assemble the expanded sealing rings 10 with the corresponding workpiece 20 placed on the conveying mechanism 420. The sealing ring 10 is expanded before being sleeved on the target workpiece 20, rather than directly installing the sealing ring 10 in the original state on the target workpiece 20 by pressing force, so that the target workpiece 20 can be prevented from being damaged by the pressing force, thereby improving the product yield and further reducing the production cost. In addition, since the support ring device and the material picking mechanism 410 are relatively independent, when multiple material picking structures respectively pick up the corresponding expanded sealing rings 10 to assemble the expanded sealing rings 10 with the corresponding workpieces 20, the support ring device can simultaneously perform the expansion work of the next batch of sealing rings 10. When the material picking mechanism 410 completes the assembly of the current batch of expanded sealing rings 10 with the corresponding workpieces 20, it can immediately pick up the next batch of expanded sealing rings 10 without reserving expansion time for the support ring device, thereby further improving the assembly efficiency.

[0059] In this embodiment, four groups of support ring mechanisms 300 are provided, and four corresponding material-retrieving structures are provided. The four groups of support ring mechanisms 300 are evenly spaced and connected to the mounting frame 500 along the A direction, and are all connected to the driving rack 210 through corresponding transmission gears 310 .

[0060] In this embodiment, the conveying mechanism 420 includes a conveying track 421 and a carrier 422. The conveying track 421 is provided on the upper end surface of the frame 100 and extends along the A direction. The carrier 422 is slidably connected to the conveying track 421, and a plurality of stations for placing the workpiece 20 are provided on the carrier 422. By providing the conveying mechanism 420, on the one hand, it is convenient to load materials to the stations on the carrier 422. On the other hand, by changing the relative position of the carrier 422 on the conveying track 421, the seized sealing ring 10 can be assembled with the workpiece 20 on the corresponding station in cooperation with the material taking mechanism 410, so as to further improve the assembly convenience and assembly efficiency.

[0061] Further, in this embodiment, the conveying track 421 and the ring support device are arranged at a relative interval in the X direction. The material taking mechanism 410 is rotatably arranged between the conveying track 421 and the ring support device and is located on one side of the ring support device. With such an arrangement, when grasping and assembling the sealing ring 10, the distance between the conveying track 421 and the ring support device can be minimized, thereby shortening the material taking path of the material taking mechanism 410, and thus improving the speed of grasping and assembling the sealing ring 10, achieving the technical effect of efficient assembly.

[0062] Preferably, the material taking mechanism 410 further includes a robotic arm assembly 411 and an object taking assembly 412. The object taking assembly 412 includes a connecting member 4121, an inner sleeve 4122, an outer sleeve 4123, and an elastic member 4124. The inner sleeve 4122, the outer sleeve 4123, and the elastic member 4124 are all provided in multiple groups corresponding to the ring support mechanism 300. The outer sleeve 4123 is sleeved on the outer periphery of the corresponding inner sleeve 4122. One end of the elastic member 4124 is connected to the first end of the inner sleeve 4122, and the other end is connected to the outer sleeve 4123 or the connecting member 4121. At least a part of the second end of the inner sleeve 4122 extends out of the end of the outer sleeve 4123 away from the connecting member 4121. The inner sleeve 4122 is configured to move relative to the outer sleeve 4123 under an external actuation.

[0063] Specifically, the robotic arm assembly 411 includes a rotating robotic arm 4111 and a lifting robotic arm 4112. The rotating robotic arm 4111 includes a rod-shaped first rotating part 41111 and a second rotating part 41112. The first end of the first rotating part 41111 is rotatably connected to the frame 100, and the first end of the second rotating part 41112 is rotatably connected to the second end of the first rotating part 41111. The lifting robotic arm 4112 is connected to the second end of the second rotating part 41112 in a lifting manner along the C direction. The connecting member 4121 is detachably connected to the lifting robotic arm 4112. By changing the angle between the first rotating part 41111 and the second rotating part 41112, the length of the rotating robotic arm 4111 can be changed to facilitate grasping the sealing ring 10. After the object taking assembly 412 grasps multiple sealing rings 10 of the placed objects, the lifting robotic arm 4112 rises along the C direction. Then, the rotating robotic arm 4111 rotates to drive the lifting robotic arm 4112 and the object taking assembly 412 to be located above the conveying mechanism 420. Then, the lifting robotic arm 4112 descends along the C direction so that the sealing rings 10 grasped by the object taking assembly 412 are sleeved on the corresponding workpieces 20 on the conveying mechanism 420.

[0064] Alternatively, the first end of the first rotating part 41111 is movably connected to the frame 100 in the X direction, the first end of the second rotating part 41112 is telescopically connected to the second end of the first rotating part 41111, and the lifting robotic arm 4112 is vertically connected to the second end of the second rotating part 41112 in the C direction. When grasping the sealing ring 10, through the reciprocating movement of the first rotating part 41111 in the X direction and the telescopic movement of the second rotating part 41112 relative to the first rotating part 41111, the grasping of the sealing ring 10 and the assembly of the sealing ring 10 and the corresponding workpiece 20 are completed. In some other embodiments, it can also be set that the first end of the first rotating part 41111 is rotatably connected to the frame 100, the first end of the second rotating part 41112 is telescopically connected to the second end of the first rotating part 41111, and the lifting robotic arm 4112 is vertically connected to the second end of the second rotating part 41112 in the C direction; or the first end of the first rotating part 41111 is movably connected to the frame 100 in the X direction, the first end of the second rotating part 41112 is rotatably connected to the second end of the first rotating part 41111, and the lifting robotic arm 4112 is vertically connected to the second end of the second rotating part 41112 in the C direction. The specific installation and connection method is set according to actual production requirements, and the technical effect of grasping and assembling the sealing ring 10 through the four-axis linkage of the robotic arm assembly 411 can be achieved, which is not limited to the examples in this embodiment.

[0065] The inner sleeve 4122 and the outer sleeve 4123 are coaxially arranged; a communication hole is opened at one end of the outer sleeve 4123 close to the connecting part 4121, and the inner sleeve 4122 is connected to the connecting part 4121 through an elastic part 4124 passing through the communication hole. A plurality of outer sleeves 4123 are sleeved on a plurality of inner sleeves 4122 one by one and are all connected to the connecting part 4121; or the outer sleeve 4123 is connected to the connecting part 4121, and the inner sleeve 4122 is connected to the inner wall of the outer sleeve 4123 close to one end of the connecting part 4121 through an elastic part 4124.

[0066] The part of the second end of the inner sleeve 4122 extending out of the outer sleeve 4123 is configured to sleeved the expanded sealing ring 10 on the ring expanding mechanism 300, and move to the position corresponding to the workpiece 20 on the conveying mechanism 420 under the drive of the robotic arm assembly 411; when the second end of the inner sleeve 4122 abuts against the corresponding working position under the drive of the robotic arm assembly 411, the inner sleeve 4122 retracts so that the grasped sealing ring 10 is sleeved on the corresponding workpiece 20 under the push of the outer sleeve 4123.

[0067] Specifically: both the inner sleeve 4122 and the outer sleeve 4123 are set in a cylindrical shape. The first end of the inner sleeve 4122 is connected to the connecting member 4121 through a corresponding elastic member 4124. The first end of the outer sleeve 4123 is fixedly connected to the connecting member 4121 and sleeved on the corresponding inner sleeve 4122. Or, both the inner sleeve 4122 and the outer sleeve 4123 are set in a cup shape. The outer side of the bottom wall of the outer sleeve 4123 is fixedly connected to the connecting member 4121. The outer sleeve 4123 is sleeved on the corresponding inner sleeve 4122. One end of the elastic member 4124 is fixedly connected to the inner side of the bottom wall of the outer sleeve 4123, and the other end is fixedly connected to the outer side of the bottom wall of the inner sleeve 4122. Or, the first end of the outer sleeve 4123 is fixedly connected to the connecting member 4121 and sleeved on the corresponding inner sleeve 4122. The first end of the inner sleeve 4122 is connected to the inner wall of the first end of the outer sleeve 4123 through a corresponding elastic member 4124. In the above three setting methods, in the original state, the second end of the inner sleeve 4122 is exposed outside the second end of the outer sleeve 4123. The working principle of the object taking assembly 412 is as follows: after the ring support device first expands multiple sealing rings 10, the robotic arm assembly 411 drives the object taking assembly 412 to move above the ring support assembly 320, and then drives the object taking assembly 412 to descend, and inserts the second ends of multiple inner sleeves 4122 into the middle parts of multiple expanded sealing rings 10 one by one. Then, the first driving assembly 200 drives the driving rack 210 to move in a direction away from the A direction, so that multiple ring support mechanisms 300 return to the original state. During this process, the sealing ring 10 is no longer subjected to the external force of the corresponding ring support mechanism 300, and begins to rebound and contract autonomously. After separating from the corresponding ring support mechanism 300, it is sleeved on the second end of the corresponding inner sleeve 4122. Then, the robotic arm assembly 411 drives the object taking assembly 412 to move above the carrier 422, and then drives the object taking assembly 412 to descend, and abuts the second ends of multiple inner sleeves 4122 against the corresponding workpieces 20 at multiple workstations one by one. As the object taking assembly 412 continues to descend, multiple elastic members 4124 are compressed, causing the inner sleeve 4122 to retract into the inner part of the outer sleeve 4123. During this process, as the relative positions of the inner sleeve 4122 and the outer sleeve 4123 change, the continuously descending outer sleeve 4123 pushes out the sealing ring 10 sleeved on the second end of the inner sleeve 4122 and pushes it onto the corresponding workpiece 20, thereby completing the assembly of the sealing ring 10 and the corresponding workpiece 20. Then, the robotic arm assembly 411 drives the object taking assembly 412 to rise, and multiple elastic members 4124 are no longer subjected to external forces and begin to rebound autonomously, driving the second end of the inner sleeve 4122 to be exposed outside the second end of the outer sleeve 4123 again, so as to facilitate the next taking of the sealing ring 10.

[0068] In some other embodiments, the outer sleeve 4123 may not be provided, and the connecting member 4121 may be directly provided as a box body, and multiple inner sleeves 4122 and elastic members 4124 are provided correspondingly. The upper end surface of the box body is connected to the second end of the lifting robot arm 4112, and the lower end surface of the box body is provided with multiple avoidance holes corresponding to the inner sleeve 4122. The first end of the inner sleeve 4122 is connected to the inner side of the upper end surface of the box body through the corresponding elastic member 4124. In the original state, the second end of the inner sleeve 4122 passes through the corresponding avoidance hole and is exposed to the lower end surface of the box body.

[0069] Preferably, the feeding device 400 also includes a feeding component 430 and a material shifting component 440. The output port of the feeding component 430 is arranged toward the support ring device. The material shifting component 440 is used to shift the sealing ring 10 in the feeding component 430 to the corresponding support ring mechanism 300 through the output port.

[0070] Specifically, the feeding assembly 430 is configured to be bucket-shaped so as to facilitate the placement of the sealing ring 10 that has not been stretched. A feeding channel (not shown in the figure) communicating with the feeding assembly 430 is provided on one side of the feeding assembly 430. The end of the feeding channel away from the feeding assembly 430 is configured as an output port, and the output port is configured correspondingly to the support ring device. A material shifting rod (not shown in the figure) is movably provided in the material shifting assembly 440, one end of which is located in the feeding channel. When the material shifting assembly 440 is in operation, the material shifting rod can shift the sealing ring 10 that has not been stretched in the feeding channel to the corresponding support ring mechanism 300. The feeding assembly 430 and the material shifting assembly 440 cooperate with each other to realize the autonomous feeding of the sealing ring 10 that has not been stretched, so as to further improve the assembly efficiency.

[0071] Preferably, the support ring device also includes a mounting frame 500, the support ring assembly 320 includes a limiting cylinder 321, an expansion disk 322, a connecting shaft 323 and a plurality of expansion rods 324, and the mounting frame 500 is movably arranged on the frame 100; corresponding to the plurality of expansion rods 324, a plurality of guide grooves 3221 are arranged on the expansion disk 322 along its circumferential intervals, and along the radial direction of the expansion disk 322, the plurality of guide grooves 3221 are all arranged to be arc-shaped grooves protruding away from the direction B; the limiting cylinder 321 is fixedly connected to the mounting frame 500, the first end of the connecting shaft 323 is fixedly connected to the lower end surface of the expansion disk 322, the second end passes through the limiting cylinder 321 and is fixedly connected to the corresponding transmission gear 310, the first ends of the plurality of expansion rods 324 all pass through the corresponding guide grooves 3221 and are movably connected to the limiting cylinder 321, and the second ends of the plurality of expansion rods 324 cooperate with each other to support the sealing ring 10.

[0072] Specifically, in the present embodiment, eight expansion rods 324 are provided, and eight guide grooves 3221 are provided on the expansion plate 322 corresponding to the expansion rods 324 . The eight guide grooves 3221 are evenly spaced along the circumference of the expansion plate 322 . When the sealing ring 10 needs to be opened, the sealing ring 10 is first placed on the second end of the eight opening rods 324, and then the first driving assembly 200 drives the driving rack 210 to move along the A direction to drive the corresponding transmission gear 310 to rotate along the B direction. At the same time, the transmission gear 310 drives the opening plate 322 to rotate along the B direction through the connecting shaft 323; and since the limiting cylinder 321 is fixedly connected to the mounting frame 500, and the first ends of the eight opening rods 324 are movably connected to the limiting cylinder 321, and the guide groove 3221 is configured to be an arc groove protruding away from the B direction along the radial direction of the opening plate 322; therefore, when the opening plate 322 rotates along the B direction, the opening rod 324 moves along the arc groove in the radial direction of the opening plate 322, so that the second end of the opening rod 324 moves in the direction away from the center of the opening plate 322. Therefore, as the transmission gear 310 drives the expansion plate 322 to move, the eight expansion rods 324 cooperate with each other to expand the sealing ring 10 placed on the second ends of the eight expansion rods 324, so as to complete the assembly of the sealing ring 10 and the target workpiece 20.

[0073] In this embodiment, the first ends of the eight spreading rods 324 pass through the corresponding guide slots 3221 and are movably connected to the limiting cylinder 321, rather than the first ends of the eight spreading rods 324 being slidably connected to the corresponding guide slots 3221; therefore, the limiting cylinder 321 cooperates with the expansion disk 322 to further adaptively limit the first ends of the eight spreading rods 324, so as to improve the connection strength and connection stability between the eight spreading rods 324 and the expansion disk 322, thereby ensuring the operation stability of the support ring assembly 320. In addition, in order to further improve the transmission accuracy, connection strength and connection stability, the expansion disk 322 and the connecting shaft 323 are integrally formed.

When the expansion rod 324 moves along the arc groove in the radial direction of the expansion disk 322, the movement of the entire expansion rod 324 is ensured to be consistent, and the expansion rod 324 is prevented from tilting, so as to further improve the operation stability of the support ring assembly 320.

[0075] Furthermore, a guide slide bar 3241 is provided at the first end of the expansion rod 324, and the axis of the guide slide bar 3241 is arranged perpendicular to the axis of the expansion rod 324. The guide slide bar 3241 is slidably connected to the corresponding guide groove 3211. The connection area between the first end of the expansion rod 324 and the guide groove 3211 is increased by the guide slide bar 3241, so as to further improve the connection strength and connection stability when the first end of the expansion rod 324 is connected to the corresponding guide groove 3211.

[0076] Furthermore, the width of the bottom end of the guide groove 3211 is greater than the width of the opening of the guide groove 3211, and correspondingly, the diameter of the guide slide bar 3241 is greater than the width of the opening of the guide groove 3211. This prevents the guide slide bar 3241 from being separated from the guide groove 3211 along the C direction when the guide slide bar 3241 slides in the corresponding guide groove 3211, so as to further improve the stability of the expansion rod 324 when it is connected to the limit cylinder 321. According to actual needs, along the length direction of the guide groove 3211, the cross-sectional area of ​​the guide groove 3211 can be set to be trapezoidal, dovetail or "⊥" shape.

[0077] In addition, in the present embodiment, at least one connecting portion 3212 is provided on the outer wall of the limiting cylinder 321, and the limiting cylinder 321 is fixedly connected to the mounting frame 500 via the connecting portion 3212; and the ends of the plurality of guide grooves 3211 which are away from the center of the limiting cylinder 321 are all arranged as closed ends, so that when the opening plate 322 rotates along the direction B so that the expansion rod 324 moves along the arc groove in the radial direction of the opening plate 322, it is possible to avoid the guide slide rod 3241 from being separated from the limiting cylinder 321 in the radial direction of the limiting cylinder 321, so as to further improve the stability of the expansion rod 324 when it is connected to the limiting cylinder 321.

[0078] Preferably, the second end of each opening rod 324 is provided with a support step 3242, and each support step 3242 is provided on the side of the opening rod 324 away from the center of the opening plate 322, and a plurality of support steps 3242 cooperate to form a support space for supporting the sealing ring 10. In this way, when the sealing ring 10 is placed on the second end of each opening rod 324, it can be ensured that the sealing ring 10 is always located in the support space, thereby preventing the sealing ring 10 from being separated from each opening rod 324, so as to ensure the opening effect of the sealing ring 10.

[0079] Preferably, the support ring assembly 320 also includes a bearing plate 325 and an auxiliary bearing 326, both of which are sleeved on the middle part of the connecting shaft 323, the bearing plate 325 is fixedly connected to the lower end surface of the limiting cylinder 321, and the auxiliary bearing 326 abuts against the inner wall of the limiting cylinder 321.

[0080] Specific combination Figure 8As shown, by setting the auxiliary bearing 326, the transmission effect between the transmission gear 310 and the connecting shaft 323 is ensured, and the connecting shaft 323 and the limiting cylinder 321 are always coaxial, so as to avoid the relative displacement between the connecting shaft 323 and the limiting cylinder 321 under the action of centrifugal force during the rotation of the connecting shaft 323, so as to further improve the movement stability of the connecting shaft 323 and the expansion plate 322 and the operation stability of the support ring assembly 320. The bearing plate 325 is sleeved on the connecting shaft 323, and the bearing plate 325 is fixedly connected to the lower end of the auxiliary bearing 326, and is connected to the lower end surface of the limiting cylinder 321 through a threaded connector 4121, so as to ensure the connection effect between the auxiliary bearing 326 and the limiting cylinder 321, so as to avoid the relative displacement between the auxiliary bearing 326 and the limiting cylinder 321 during the rotation of the connecting shaft 323. The auxiliary bearing 326 is set as a rolling bearing, and the specific structure refers to the prior art, which will not be repeated here.

[0081] Preferably, the mounting frame 500 is configured as a box body, and the driving rack 210 and the multiple groups of support ring mechanisms 300 are all arranged in the mounting frame 500; the top plate of the mounting frame 500 is provided with mounting channels corresponding to the multiple groups of support ring mechanisms 300, the outer peripheral wall of the expansion disk 322 abuts against the inner wall of the corresponding mounting channel, the limiting cylinder 321 is fixedly connected to the top plate of the mounting frame 500 corresponding to the expansion disk 322, and the two side walls of the mounting frame 500 spaced apart along the A direction are provided with avoidance holes 510 for allowing the driving rack 210 to pass through.

[0082] Specifically, the drive rack 210 and the multiple support ring mechanisms 300 are both arranged in the mounting frame 500. The mounting frame 500 protects the drive rack 210 and the multiple support ring mechanisms 300, prevents external debris or other structures from damaging the drive rack 210 or the multiple support ring mechanisms 300, ensures the use effect of the expansion device, and prolongs its service life. The limit cylinder 321 is fixedly connected to the top plate of the mounting frame 500 through the connecting portion 3212, and the upper end of the limit cylinder 321 is inserted into the corresponding installation channel, so that the ends of the multiple guide grooves 3211 away from the center of the limit cylinder 321 are all abutted against the inner wall of the installation channel to form a closed end, and the outer peripheral wall of the expansion plate 322 is abutted against the corresponding installation channel, so that the second ends of the multiple expansion rods 324 pass through the corresponding guide grooves 3221 and extend out of the mounting frame 500, so as to improve the convenience of expanding the sealing ring 10. Since avoidance holes 510 are provided on the two side walls of the mounting frame 500 which are spaced apart along direction A, when the first driving assembly 200 drives the driving rack 210 to move along direction A, both ends of the driving rack 210 can extend from the corresponding avoidance holes 510 without leaving avoidance space in the mounting frame 500, thereby improving the compactness of the internal components of the mounting frame 500 and reducing the spatial volume of the mounting frame 500.

[0083] Preferably, the ring support device further includes a support plate 700 and a second drive assembly 600; the mounting bracket 500 is movably arranged on the frame 100, the support plate 700 is fixedly arranged above the mounting bracket 500, and accommodating grooves allowing the ring support assemblies 320 to pass through are correspondingly arranged on the support plate 700 for multiple groups of ring support mechanisms 300. The second drive assembly 600 is arranged on the frame 100, and the second output shaft of the second drive assembly 600 is in transmission connection with the mounting bracket 500 to drive the mounting bracket 500 to move up and down in the C direction.

[0084] Specifically, four circular accommodating grooves are correspondingly arranged on the support plate 700. When the second drive assembly 600 drives the mounting bracket 500 to move up in the C direction, the second ends of multiple expanding rods 324 in each group of ring support mechanisms 300 extend above the support plate 700 through the corresponding accommodating grooves.

[0085] Combined with the mounting bracket 500 and the ring support mechanism 300, the working process of the entire ring support device is as follows: First, place the unsealed sealing ring 10 on the support plate 700 corresponding to the accommodating groove. Then, the second drive assembly 600 drives the mounting bracket 500 to move up in the C direction, so that the second ends of multiple expanding rods 324 in each group of ring support mechanisms 300 extend above the support plate 700 through the corresponding accommodating grooves. As the mounting bracket 500 moves up, the second ends of multiple expanding rods 324 in each group of ring support mechanisms 300 all pass through the corresponding sealing ring 10, so that the sealing ring 10 is located in the corresponding support space. Then, the first drive assembly 200 drives the drive rack 210 to move in the A direction, so that multiple expanding rods 324 in each group of ring support mechanisms 300 all move in a direction away from the center of the expansion disc 322, so that the sealing ring 10 in the support space is expanded, so as to facilitate the sleeving of the expanded sealing ring 10 on the inner sleeve 4122. Then, the first drive assembly 200 drives the drive rack 210 to move in a direction away from the A direction, so that multiple expanding rods 324 in each group of ring support mechanisms 300 are reset. Then, the second drive assembly 600 drives the mounting bracket 500 to move down in the C direction, and place the unsealed sealing ring 10 on the support plate 700 corresponding to the accommodating groove again, and repeat the above steps.

[0086] Further, a plurality of support teeth are provided on the inner wall of the accommodation groove. The plurality of support teeth are evenly spaced along the circumferential direction of the accommodation groove, and an avoidance groove is formed between two adjacent support teeth. Before the supporting and installing mechanism works, the unsealed sealing ring 10 is placed on the plurality of support teeth in the corresponding accommodation groove to limit the relative position of the unsealed sealing ring 10 in this state and prevent the unsealed sealing ring 10 from slipping off the support plate 700. An avoidance groove is formed between two adjacent support teeth, and eight avoidance grooves are provided along the circumferential direction of the accommodation groove. When the second driving component 600 drives the mounting bracket 500 to rise along the C direction, the eight expanding rods 324 respectively extend above the support plate 700 from the eight avoidance grooves. The eight avoidance grooves cooperate with each other to further improve the stability of the eight expanding rods 324 during the rising process, thereby further ensuring the expanding effect on the sealing ring 10.

[0087] In addition, according to actual requirements, the first driving component 200 and the second driving component 600 can be set as air cylinders, push rod motors, etc. For specific reference, refer to the prior art, and no specific limitation is made in this embodiment.
