Description

Technical Field

[0001] This utility model relates to the field of medical consumable production equipment, and in particular to an assembly device for sealing rings. Background Technology

[0002] In the use of medical devices and consumables, sealing performance is crucial. Sealing rings are one of the key components used to ensure this performance. Traditional sealing rings are mostly circular in cross-section, and their automated assembly has been widely researched and applied. However, for certain specialized applications, rectangular cross-section sealing rings are more suitable.

[0003] However, the automated assembly of rectangular cross-section sealing rings presents certain challenges due to their unique cross-sectional shape. Traditional automated assembly solutions for circular sealing rings cannot be directly applied to rectangular cross-section sealing rings. The main reason is that the circular cross-section of a sealing ring has a tapering inner ring, making it relatively easy to fit onto a cylinder for transport. However, rectangular cross-section sealing rings do not exhibit this tapering inner ring characteristic, making it impossible to use a cylinder for transport and installation into the material. Furthermore, when the sealing ring needs to be installed inside the material, it is difficult to use clamping methods for transport and installation of the rectangular cross-section sealing ring. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to design an assembly device for sealing rings, thereby solving the technical problem of automated handling and assembly of rectangular cross-section sealing rings.

[0005] An assembly apparatus for a sealing ring includes a transfer platform, a loading assembly, and a pick-and-place mechanism. The transfer platform has a placement platform for placing the sealing ring. The pick-and-place mechanism drives the loading assembly to move closer to or further away from the placement platform. The loading assembly includes a clamping member, a clamping rod, and a driving member. A limiting portion on the clamping member extends into the inner ring of the sealing ring. The driving member drives a pressing portion of the clamping rod to apply a pressing force to the sealing ring outside the inner ring. The limiting portion maintains the sealing ring in a specific shape, and the sealing ring is clamped by the combined action of the limiting portion and the pressing portion.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: By restricting the shape of the sealing ring through the limiting part and then deforming the sealing ring through the extrusion part, the sealing ring is transformed from a circular shape with a large outer diameter into an irregular shape. The maximum external dimension of the deformed irregular-shaped sealing ring is smaller than that of the circular shape, allowing the sealing ring to be placed inside the material to be assembled. Because the sealing ring is clamped through the combined action of the limiting part and the extrusion part, it is not necessary to move the sealing ring by tightly fitting the limiting part to the sealing ring. Therefore, the size of the limiting part can be designed to be smaller than the inner ring of the sealing ring, allowing the limiting part to easily extend into the inner ring of the sealing ring, thus achieving automated handling and assembly of rectangular cross-section sealing rings.

[0007] In the above-described assembly device for a sealing ring, the limiting portion has a position for accommodating the extrusion portion.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the position on the limiting part to accommodate the extrusion part ensures that after the limiting part and the extrusion part work together to clamp the sealing ring, the overall circumferential dimensions of the limiting part, the extrusion part and the sealing ring are not too large, further avoiding the situation where the sealing ring cannot be transferred into the material due to the excessive circumferential dimensions.

[0009] In the above-mentioned assembly device for sealing rings, the assembly device further includes a rotary material picking mechanism and a transfer and translation mechanism. The transfer and translation mechanism includes the transfer table. The rotary material picking mechanism is used to pick up the sealing ring and place it on the transfer table. The transfer and translation mechanism is used to drive the transfer table to move closer to the rotary material picking mechanism or to move closer to the picking and placing mechanism.

[0010] In the above-mentioned assembly device for sealing rings, the rotating material handling mechanism includes a platform one, a rotating cylinder, a translation cylinder two, and a gripper cylinder. The platform one is fixedly connected to the frame, the rotating cylinder is disposed on the platform one, the translation cylinder two is connected to the drive end of the rotating cylinder, and the gripper cylinder is connected to the drive end of the translation cylinder two. Two finger grippers are also disposed on the drive end of the gripper cylinder. The rotating cylinder drives the finger grippers to turn towards the transfer and translation mechanism or the material handling position, the translation cylinder two drives the finger grippers to move closer to or away from the transfer and translation mechanism, and the gripper cylinder drives the two finger grippers to move closer to or away from each other.

[0011] In the above-mentioned assembly device for sealing rings, the rotary material handling mechanism further includes a movable plate and a translation cylinder. The movable plate is slidably disposed on the platform, the translation cylinder is fixedly disposed on the platform, the drive end of the translation cylinder is connected to the movable plate, and the rotary cylinder is fixedly disposed on the movable plate.

[0012] In the above-mentioned assembly device for sealing rings, the transfer and translation mechanism further includes a platform two, a moving plate two, and a translation cylinder three. The platform two is fixedly connected to the frame, the moving plate two is slidably disposed on the platform two, the translation cylinder three is fixedly disposed on the platform two, the driving end of the translation cylinder three is connected to the moving plate two, the transfer table is fixedly connected to the moving plate two, the translation cylinder three drives the transfer table to move, and the transfer table also has a blocking part, which is disposed on the upper surface of the placement platform and disposed on both sides along the moving direction of the transfer table.

[0013] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that by setting a blocking part on the placement platform, the sealing ring can be prevented from being thrown out during the movement of the transfer platform.

[0014] In the above-mentioned assembly device for sealing rings, the middle part of the placement platform has a clearance groove, the transfer platform also includes two upper baffles, the two upper baffles are respectively fixedly disposed on the blocking parts on both sides, there is a gap between the two upper baffles, and each upper baffle also has a clearance arc, the clearance arc is disposed on one side of the gap.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: The clearance groove avoids the finger gripper, allowing the finger gripper to extend close to the placement platform between the two blocking parts. When the two finger grippers release their restriction on the sealing ring, the deformation of the sealing ring is limited by the blocking parts, which then position the sealing ring. This allows the clamping component to more accurately extend into the inner ring of the sealing ring. The upper baffle limits the vertical height of the sealing ring, and the clearance arc avoids the clamping component.

[0016] In the above-mentioned assembly device for sealing rings, the loading assembly further includes a mounting plate and a translation cylinder four. The mounting plate is connected to the pick-and-place mechanism. The clamping member is provided on the side of the mounting plate near the transfer and translation mechanism. The translation cylinder four is fixedly mounted on the mounting plate and its driving end is connected to the clamping rod. The translation cylinder four drives the clamping rod to move closer to or away from the clamping member.

[0017] In the above-mentioned assembly device for sealing rings, the translation cylinder four is disposed on the side of the mounting plate opposite to the clamping member. The mounting plate has an avoidance notch. The translation cylinder four drives the clamping rod to move in the avoidance notch. The loading assembly also includes a lifting cylinder one, which is fixedly connected to the driving end of the translation cylinder four. The clamping rod is connected to the driving end of the lifting cylinder one, which drives the clamping rod to move in the vertical direction. The clamping member also includes a stop part one, and the clamping rod also includes a stop part two.

[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: The lifting cylinder one can drive the clamping rod to move vertically. After the limiting part and the squeezing part clamp and move the sealing ring into the material, the translation cylinder four does not move the clamping rod initially. The lifting cylinder one first drives the clamping rod upward. When the height of the squeezing part is completely higher than the sealing ring, the sealing ring loses the squeezing pressure and deforms, returning to its circular shape. This design is more conducive to the separation of the limiting part and the squeezing part from the sealing ring when the internal space of the material is limited. The function of the blocking part one and the stop part two is to limit the height position of the sealing ring after it is clamped and to prevent the sealing ring from being moved upward during the upward movement of the squeezing part.

[0019] In the above-mentioned assembly device for sealing rings, the picking and placing mechanism further includes a platform three, a movable plate three, a guide rod, a lifting cylinder two, and a translation cylinder five. The platform three is fixedly connected to the frame. The movable plate three is slidably disposed on the platform three. The guide rod is slidably disposed on the movable plate three, and its end near the transfer table is connected to the loading assembly. The lifting cylinder two is fixedly disposed on the movable plate three, and its driving end is disposed through the movable plate three and connected to the loading assembly. The translation cylinder five is fixedly disposed on the platform three, and its driving end is connected to the movable plate three.

[0020] By applying the technical solution of this utility model, the sealing ring is gripped and placed onto the placement platform using finger grippers. The platform then positions the sealing ring using its transport and blocking components. Through the combined action of the limiting and squeezing components, the sealing ring can be precisely gripped and transferred, no longer limited by its shape. This solution effectively grasps, transports, and installs rectangular cross-section sealing rings into the material, thereby improving production efficiency and reducing labor costs.

[0038] See Figure 1 The cross-section of the sealing ring 50 is non-circular. In the following embodiments, the cross-section can be rectangular, rectangular with a groove, square, or naturally circular.

[0039] See Figure 1-5 ,like Figure 1The sealing ring assembly device shown includes a rotary material handling mechanism 10, a transfer and translation mechanism 20, a loading assembly 30, and a pick-and-place mechanism 40, all mounted on a frame. The rotary material handling mechanism 10 picks up a sealing ring 50 from a rectangular cross-section sealing ring feeding device (not shown in the figures) on one side. The rotary material handling mechanism 10 drives a pair of finger grippers 18 to extend into the inner ring of the sealing ring 50. Driven by a gripper cylinder 17, they move away from each other, pulling the sealing ring 50 along the two sides where the grippers 18 are moving away from each other. The sealing ring 50 is stretched into a long strip and its movement is restricted by the two finger grippers 18. Driven by a rotary cylinder 15, the sealing ring 50 rotates 90 degrees, changing its position from vertical to horizontal. At this time, the transfer platform 24 in the transfer and translation mechanism 20 is located below the sealing ring 50. Driven by the translation cylinder 16, the sealing ring 50 approaches the transfer platform 24. When the sealing ring 50 approaches the placement platform 241, the gripper cylinder 17 drives the two finger grippers 18 to approach each other. The two finger grippers 18 release the constraint on the sealing ring 50, and the sealing ring 50 falls onto the placement platform 241, and the sealing ring 50 returns to a circular shape.

[0040] The transfer platform 24 moves horizontally, causing the sealing ring 50 to move to the material-receiving position. At this time, the loading assembly 30, located above the transfer platform 24, moves closer to the transfer platform 24 under the action of the picking and placing mechanism 40. The loading assembly 30 includes a clamping member 32 and a clamping rod 34. The clamping member 32 extends into the inner ring of the sealing ring 50 placed on the transfer platform 24, and the clamping rod 34 descends simultaneously to the outside of the inner ring of the sealing ring 50. When the clamping member 32 and the clamping rod 34 reach the predetermined material-receiving position, the clamping rod 34 is driven to move closer to the clamping member 32. The clamping rod 34 continues to move until the sealing ring 50 is tightened, and the shape of the sealing ring 50 changes to a horseshoe shape. At this time, the inner ring of the sealing ring 50 is tightly pressed against the clamping member 32 under the squeezing action of the clamping rod 34. Driven by the pick-and-place mechanism 40, the sealing ring 50 is moved out of the transfer table 24 and moved toward the material where the sealing ring 50 needs to be assembled. After the sealing ring 50 is moved into the material, the clamping rod 34 is driven away from the clamping member 32, releasing the constraint on the sealing ring 50. After the clamping member 32 and the clamping rod 34 are away from the sealing ring 50, the shape of the sealing ring 50 returns to a circular shape, and the assembly of the sealing ring 50 is completed.

[0041] This solution effectively grips the rectangular cross-section sealing ring 50, preventing damage during handling. The assembly of the sealing ring 50 is completed, successfully solving the assembly challenge of rectangular cross-section sealing rings 50 and achieving efficient and reliable assembly.

[0042] The structure of each part will be described in detail below with reference to the attached diagram.

[0043] See Figure 1The rotary material handling mechanism 10, the intermediate transfer mechanism 20, and the pick-and-place mechanism 40 are all mounted on the frame, and the loading assembly 30 is mounted on the pick-and-place mechanism 40. The rotary material handling mechanism 10 removes the sealing ring 50 from the feeding device (not shown) and places it on the intermediate transfer mechanism 20. The intermediate transfer mechanism 20 moves the sealing ring 50 to below the loading assembly 30. After the loading assembly 30 retrieves the sealing ring 50 from the intermediate transfer mechanism 20, it is moved by the pick-and-place mechanism 40 to the material to be assembled. This assembly device has two rotary material handling mechanisms 10, an intermediate transfer mechanism 20, and a loading assembly 30, as shown below. Figure 1 The two rotating material handling mechanisms 10, the transfer and translation mechanism 20, and the loading assembly 30 are symmetrically distributed according to the handling mechanism 40, and can be used as follows: Figure 1 The two rotating material handling mechanisms 10, the two intermediate transfer mechanisms 20, and the picking and placing mechanism 40 described herein are arranged in a straight line. Alternatively, the rotating material handling mechanisms 10, the intermediate transfer mechanisms 20, and the picking and placing mechanism 40 may be arranged in a straight line, with the two rotating material handling mechanisms 10 and the two intermediate transfer mechanisms 20 arranged side by side.

[0044] For details, see Figure 2The rotary material handling mechanism 10 includes a support 11, a platform 12, a movable plate 13, a translation cylinder 14, a rotary cylinder 15, a second translation cylinder 16, a gripper cylinder 17, and finger grippers 18. The support 11 is fixed to the machine frame, and the platform 12 is mounted on top of the support 11. The movable plate 13 is slidably mounted on the platform 12, and the translation cylinder 14 is fixedly mounted on the platform 12. The drive end of the translation cylinder 14 is connected to the movable plate 13, driving the movable plate 13 to move horizontally. The rotary cylinder 15 is fixedly mounted on the movable plate 13. The second translation cylinder 16 is mounted on the drive end of the rotary cylinder 15 and can be driven to rotate by the rotary cylinder 15. The gripper cylinder 17 is mounted on the drive end of the second translation cylinder 16 and can be driven to translate by the second translation cylinder 16. Two finger grippers 18 are respectively mounted on the two driving fingers of the gripper cylinder 17. The two finger grippers 18 can be driven by the gripper cylinder 17 to move away from or towards each other. The sealing ring feeding device (not shown in the figure) is located on one side of the rotating feeding mechanism 10. When feeding is required, the two finger grippers 18 are close to each other, with the end of the finger gripper 18 away from the gripper cylinder 17 facing the sealing ring feeding device. When the sealing ring 50 on the sealing ring feeding device reaches the feeding position, the translation cylinder 14 drives the moving plate 13 to move closer to the sealing ring 50, while the translation cylinder 16 drives the gripper cylinder 17 to move closer to the sealing ring 50. Under the combined action of the translation cylinder 14 and the translation cylinder 16, the finger grippers 18 are inserted into the inner ring of the sealing ring 50. Driven by the gripper cylinder 17, the two finger grippers 18 move away from each other, pulling the sealing ring 50 in the direction of their separation, causing the sealing ring 50 to deform into a long strip shape. The sealing ring 50 is restrained by the pull of the two finger grippers 18. After the sealing ring 50 is constrained by the two finger grippers 18, the translation cylinder 14 and the second translation cylinder 16 are simultaneously driven to return the gripper cylinder 17 to its initial position. Then, driven by the rotary cylinder 15, the second translation cylinder 16 rotates, thereby driving the gripper cylinder 17 to rotate, causing the two finger grippers 18, carrying the sealing ring 50, to change from a vertical state to a horizontal state. Driven by the second translation cylinder 16, the two finger grippers 18, carrying the sealing ring 50, approach the transfer and translation mechanism 20.

[0045] It should be noted that the platform 12 driving moving plate 13 can be omitted, and the sealing ring feeding device can complete the step of bringing the sealing ring 50 close to the rotating material taking mechanism 10; or it can be replaced by the translation cylinder 2 16, and replacing the translation cylinder 2 16 with a longer stroke can also achieve the same effect.

[0046] It should be noted that when the gripper cylinder 17 opens and closes vertically, the sealing ring 50 is pulled into a vertical position. If the gripper cylinder 17 opens and closes horizontally, the sealing ring 50 is pulled into a horizontal position. After being rotated 90° by the rotary cylinder 15, although it remains horizontal, the axial direction of the sealing ring changes from horizontal to vertical. The gripper cylinder 17 can open and close in a cross manner or in a translational manner.

[0047] For details, see Figure 1 and Figure 3 The transfer and translation mechanism 20 includes a second support 21, a second platform 22, a second movable plate 23, a transfer table 24, a connecting member 25, and a third translation cylinder 26. The second support 21 is fixed to the frame, and the second platform 22 is mounted on top of the second support 21. The second movable plate 23 is slidably mounted on the second platform 22. The third translation cylinder 26 is fixedly mounted on the second platform 22, and its drive end is connected to the second movable plate 23 to drive the second movable plate 23 to move horizontally. The connecting member 25 is fixedly mounted on the second movable plate 23, and the transfer table 24 is mounted on top of the connecting member 25. The transfer table 24 includes a placement platform 241 and a blocking part 242. The placement platform 241 is used to place the sealing ring 50 that has lost the constraint of the two finger grippers 18. Blocking parts 242 are provided on both sides of the transfer table 24 along the moving direction of the second movable plate 23. During the movement of the sealing ring 50 by the transfer platform 24, the blocking part 242 limits the sealing ring 50 on the placement platform 241 to prevent it from being thrown out during the movement. The blocking part 242 can be a protrusion or a protruding rod protruding from the placement platform 241. A clearance groove 244 is also provided in the middle of the placement platform 241 to avoid the finger clamp 18. An upper baffle 243 is also provided on the upper end face of the blocking part 242, and the two upper baffles 243 are respectively connected to the blocking parts 242 on both sides. The upper baffles 243 limit the height of the sealing ring 50 on the placement platform 241. There is a gap between the two upper baffles 243, which is used to avoid the finger clamp 18 and the clamping rod 34 that hold the sealing ring 50. The two finger clamps 18 can pass through the gap with the sealing ring 50, and the clamping rod 34 can move in the gap when it approaches the clamping member 32.

[0048] Furthermore, when the two upper baffles 243 are close together, in addition to avoiding the sealing ring 50 and the finger clamp 18, they also need to avoid the clamping member 32. Therefore, there are avoidance arcs 245 on both upper baffles 243, and the avoidance space formed by the two avoidance arcs 245 needs to be sufficient for the clamping member 32 that clamps the sealing ring 50 to pass through.

[0049] For details, see Figure 1 , Figure 4 and Figure 5The loading assembly 30 includes a mounting plate 31, a clamping member 32, a translation cylinder 33, a clamping rod 34, a fixing block 35, and a lifting cylinder 36. The mounting plate 31 is fixedly connected to the guide rod 43 in the loading and unloading mechanism 40, and is located at the end of the guide rod 43 near the transfer and translation mechanism 20. The clamping member 32 is fixedly mounted on the side of the mounting plate 31 near the transfer and translation mechanism 20. The clamping member 32 has a limiting part 321, which is used to extend into the inner ring of the sealing ring 50. The clamping part 341 in the clamping rod 34 cooperates with the limiting part 321 to compress and tighten the sealing ring 50. The clamping rod 34 is fixedly mounted on the drive end of the lifting cylinder 36 via the fixing block 35. The lifting cylinder 36 is fixedly mounted on the drive end of the translation cylinder 33, which is fixed on the side of the mounting plate 31 opposite to the clamping member 32. The translation cylinder 33 can drive the lifting cylinder 36 to move horizontally, causing the extrusion section 341 to move closer to or further away from the limiting section 321. The lifting cylinder 36 can drive the clamping rod 34 to rise or fall, raising the extrusion section 341 to a horizontal height higher than the limiting section 321. An clearance notch 311 is also provided on the mounting plate 31 to allow the clamping rod 34 to pass. When the translation cylinder 33 drives the clamping rod 34 closer to the clamping member 32, the clamping rod 34 moves within the clearance notch 311.

[0050] It should be noted that the function of the lifting cylinder 36 is to allow the sealing ring 50 to return to its circular shape after it has been moved into the material by the clamping member 32 and the clamping rod 34. The upward pressing part 341 of the clamping rod 34 moves away from the sealing ring 50 first. Therefore, the lifting cylinder 36 can be omitted. After the sealing ring 50 is moved into the material by the clamping member 32 and the clamping rod 34, the clamping rod 34 is directly driven by the translation cylinder 33 to move horizontally away from the clamping member 32, thus allowing the sealing ring 50 to return to its circular shape as well.

[0051] Furthermore, in order to enable the clamping member 32 and the clamping rod 34 to cooperate in compressing and tightening the sealing ring 50, the limiting part 321 in the clamping member 32 can be designed as a horseshoe shape, and the limiting part 321 has a position to accommodate the compressing part 341, such as... Figure 5 When the extrusion part 341 moves closer to the restriction part 321, it is positioned within the horseshoe-shaped U-shaped opening. The originally circular sealing ring 50 is compressed into a horseshoe shape. The inner sidewall of the sealing ring 50 is tightly pressed against the outer sidewall of the restriction part 321, and the extrusion part 341 tightly presses against the outer sidewall of the sealing ring 50. This allows the sealing ring 50 to be moved by the clamping member 32 and the clamping rod 34. The maximum outer diameter of the restriction part 321 must be smaller than the inner diameter of the sealing ring 50 so that the restriction part 321 can be easily inserted into the easily deformable inner ring of the sealing ring 50. Besides being designed as a horseshoe shape, the restriction part 321 can also be replaced by multiple protruding pillars, such as... Figure 6As shown, multiple convex cylindrical limiting portions 321 are inserted into the inner ring of the sealing ring 50. The outer cylindrical surface of the limiting portion 321 can block the inner ring of the sealing ring 50 and can play the same role as the horseshoe-shaped limiting portion 321 described above.

[0052] It should be noted that after the clamping member 32 and the clamping rod 34 clamp the sealing ring 50, the maximum circumferential dimension of the sealing ring 50 plus the clamping rod 34 must be smaller than the inner diameter of the material. Only in this way can the sealing ring 50 be sent into the interior of the material through the clamping member 32 and the clamping rod 34.

[0053] Furthermore, the clamping member 32 also has a first stop portion 322, and the clamping rod 34 also has a second stop portion 342. The first stop portion 322 and the second stop portion 342 are larger than the limiting portion 321 and the squeezing portion 341 in their circumferential outer diameters, respectively. The function of the first stop portion 322 and the second stop portion 342 is to block the sealing ring 50, preventing the sealing ring 50 from undergoing significant displacement relative to the limiting portion 321 during the squeezing and clamping process. The advantage of this design is that it accurately positions the sealing ring 50. After the sealing ring 50 is moved to the material, it can be precisely positioned in the sealing ring 50 mounting groove of the material after being released by the squeezing portion 341.

[0054] For details, see Figure 1The loading and unloading mechanism 40 includes a platform 3 41, a movable plate 3 42, a guide rod 43, a lifting cylinder 2 44, a translation cylinder 5 45, and a bracket 3 46. The bracket 3 46 is fixed to the frame, and the platform 3 41 is mounted on top of the bracket 3 46. The movable plate 3 42 is slidably mounted on the platform 3 41 and has a linear bearing. The guide rod 43 passes through the linear bearing and can move up and down relative to the movable plate 3 42. One end of the guide rod 43 near the transfer and translation mechanism 20 is fixedly connected to the loading assembly 30. The lifting cylinder 2 44 is fixed to the movable plate 3 42, and its drive end is connected to the loading assembly 30, driving the loading assembly 30 to move up and down along the direction guided by the guide rod 43. The translation cylinder 5 45 is fixed to the platform 3 41, and its drive end is connected to the movable plate 3 42, driving the movable plate 3 42 to move horizontally along the slidably mounted guide direction. The specific steps of the loading and unloading mechanism 40 driving the loading assembly 30 to clamp the sealing ring 50 include: the translation cylinder 45 drives the moving plate 3 42 to translate, so that the loading assembly 30 is moved to the top of the transfer translation mechanism 20. At this time, the transfer platform 24 is located on the side close to the loading and unloading mechanism 40. The loading assembly 30 is driven by the lifting cylinder 2 44 to move closer to the transfer platform 24. The clamping member 32 in the loading assembly 30 passes through the avoidance arc 245 in the transfer platform 24. The limiting part 321 of the clamping member 32 extends into the inner ring of the sealing ring 50. The squeezing part 341 of the clamping rod 34 is located outside the inner ring of the sealing ring 50. The clamping rod 34 is driven by the translation cylinder 4 33 to move closer to the clamping member 50. As the holder 32 moves, the clamping rod 34 moves in the gap between the two upper baffles 243. The extrusion part 341 abuts against the outer wall of the sealing ring 50. As the clamping rod 34 continues to move, the sealing ring 50 begins to deform and shrink. When the extrusion part 341 moves into the horseshoe-shaped U-shaped opening of the limiting part 321, the inner wall of the sealing ring 50 abuts against the limiting part 321. Under the combined action of the extrusion of the extrusion part 341 and the limiting of the limiting part 321, the sealing ring 50 is tightened and clamped. After the sealing ring 50 is clamped, the lifting cylinder 2 44 drives the loading assembly 30 to move upward, and the translation cylinder 5 45 drives the loading assembly 30 holding the sealing ring 50 to move to the material with the assembled sealing ring 50.
