DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] An embodiment of a rubber sealing ring quick assembly device of the present invention is as follows Figures 1 to 12 shown.

[0021] A rubber sealing ring quick assembly device for assembling a sealing ring 300 includes a connecting tube 100 and an assembly mechanism 200. The assembly mechanism 200 includes a rotating disk 210 and four expansion assemblies. The rotating disk 210 is mounted on the connecting tube 100 so as to be rotatable about its own axis. The direction of the rotating axis of the rotating disk 210 is referred to as a first direction.

[0022] Four expansion assemblies are evenly spaced about the first direction on the rotating disk 210. A sealing ring 300 is mounted on the expansion assemblies. The expansion assembly includes an adjustment portion 220 and a mating rod 230. Initially, the four adjustment portions 220 and the four mating rods 230 form a square. The adjustment portions 220 and mating rods 230 are arranged sequentially in the direction of rotation of the rotating disk 210. Initially, the four adjustment portions 220 are located at the four corners of the square. The angle between the mating rods 230 and their corresponding adjustment portions 220 is 45°.

[0023] The adjustment unit 220 includes an active rod 221, a transmission member, a housing 222, and two adjustment rings 223. The active rod 221 is arranged along a first direction on the rotating disk 210. Rotation of the rotating disk 210 about its own axis can cause the active rod 221 to move in a second direction, which is the radial direction of the rotating disk 210.

[0024] Two adjustment rings 223 are arranged sequentially along the first direction on the active rod 221 and connected by a transmission member. The housing 222 is resilient and mounted outside the two adjustment rings 223. The transmission member, housing 222, and the two adjustment rings 223 are all capable of moving in the second direction with the active rod 221. The mating rod 230 is arranged along the first direction and is capable of moving synchronously with the adjustment rings 223. The sealing ring 300 contacts the housing 222 and the mating rod 230. When the active rod 221 moves in the second direction away from the rotation axis of the rotating disk 210 and activates the transmission member through the sealing ring 300, the transmission member actuates, causing the two adjustment rings 223 to move away from each other in the first direction and rotate each of the adjustment rings 223 about its own axis. The rotation of the adjustment rings 223 about their own axis causes the mating rods 230 to move in the second direction, transforming the square formed by the four adjustment portions 220 and the four mating rods 230 into an octagon.

[0025] For the convenience of description, the side closer to the rotation axis of the rotating disk 210 along the second direction is called inner, and the side farther from the rotation axis of the rotating disk 210 is called outer.

[0026] During use, the rotating disk 210 is first driven to rotate about its own axis, thereby causing the active rod 221 to move inwardly along the second direction on the rotating disk 210. The movement of the active rod 221 drives the transmission member, the outer shell 222, and the two adjustment rings 223 to move synchronously. The movement of the active rod 221 in the second direction also drives the synchronous movement of the matching rod 230. In other words, the rotation of the rotating disk 210 about its own axis causes the entire diameter expansion assembly to move inwardly along the second direction on the rotating disk 210, reducing the outer diameter of the four diameter expansion assemblies and adapting them to the sealing ring 300 in its natural state. This allows the four diameter expansion assemblies to be inserted into the inner ring of the sealing ring 300, and the sealing ring 300 is positioned on the outer shell 222 of the diameter expansion assembly.

[0027] Then, the rotating disk 210 is driven to rotate around its own axis, thereby moving the four expanding assemblies outward along the second direction on the rotating disk 210, so that the outer diameters of the four expanding assemblies become larger, and the sealing ring 300 is expanded synchronously by the expanding assemblies.

[0028] During this process, when the diameter of the sealing ring 300 with low hardness and good elasticity is expanded, the sealing ring 300 is more likely to deform. When the diameter of the sealing ring 300 is expanded, the force exerted by the outer shell 222 to squeeze the transmission member is small, and the sealing ring 300 will not drive the transmission member to move. At this time, the two adjustment rings 223 remain stationary and will not cause the matching rod 230 to move further outward in the second direction. Therefore, during the process of the rotating disk 210 rotating around its own axis, the diameter expansion component will expand proportionally, and the square structure enclosed by the four adjustment parts 220 and the four matching rods 230 will remain unchanged, and will drive the sealing ring 300 to expand synchronously. See Appendix. Figure 3 and attached Figure 4 The radius of the inscribed circle of the expanded sealing ring 300 is a preset value R1, which is the radius required for the sealing ring 300 to be assembled. The side length of the quadrilateral in which the expanded sealing ring 300 is located is X.

[0029] When the diameter of the sealing ring 300, which has high hardness and poor elasticity, is expanded, the sealing ring 300 is not easily deformed. Therefore, when the diameter of the sealing ring 300 is expanded, the sealing ring 300 exerts a greater force on the outer shell 222, and the sealing ring 300 will squeeze the transmission member through the outer shell 222. The transmission member's action can cause the two adjustment rings 223 to rotate around their own axes respectively, and the rotation of the adjustment rings 223 around their own axes can cause the matching rods 230 to move further outward in the second direction. During the process of the rotating disk 210 rotating around its own axis, the diameter expansion component will be pushed further outward by the matching rods 230 on the basis of the overall expansion, and the square enclosed by the four adjustment parts 220 and the four matching rods 230 will gradually become an octagon. See the attached figure. Figure 5 and attached Figure 6 As shown, the radius of the inscribed circle of the expanded sealing ring 300 is a preset value R1, and the side length of the octagon in which the expanded sealing ring 300 is located is Y. After determining the radius of the inscribed circle of the expanded sealing ring 300, the amount of rotation of the rotating disk 210 can be adjusted by calculating the distance that the active rod 221 moves in the second direction.

[0030] Calculation shows that 4X is less than 8Y, meaning that when the diameter of the sealing ring 300 with high hardness and poor elasticity is expanded, the square formed by the four adjustment portions 220 and the four matching rods 230 is changed into an octagon. This allows the sealing ring 300 to be assembled after expansion with a relatively reduced overall deformation (relative to a quadrilateral), thereby minimizing excessive deformation of the sealing ring 300 during expansion and extending the service life of the sealing ring 300.

[0031] In this embodiment, the transmission member includes two movable rings 224 and a plurality of connecting members 225. The two movable rings 224 are sequentially arranged on the active rod 221 along a first direction and are rotatably engaged with the active rod 221. The housing 222 is connected to the two movable rings 224 at both ends along the first direction. The two movable rings 224 and the two adjustment rings 223 are arranged in a one-to-one correspondence, and each adjustment ring 223 is located on a side of its corresponding movable ring 224 that is away from the other movable ring 224 in the first direction. The plurality of connecting members 225 are evenly distributed between the two movable rings 224 along the first direction. The active rod 221 is a threaded rod. The two adjustment rings 223 are each sleeved on the active rod 221 and threadedly engaged with the active rod 221. Both adjustment rings 223 can move synchronously with their corresponding movable rings 224 in the first direction and can rotate about their own axes relative to their corresponding movable rings 224. Specifically, an annular groove is provided on the outer peripheral wall surface of the movable ring 224, and an annular protrusion is provided on the adjustment ring 223 around the first direction. The annular protrusion rotates with the corresponding annular groove, so that the two adjustment rings 223 can move synchronously with the corresponding movable ring 224 in the first direction, and can rotate around their own axis relative to the corresponding movable ring 224.

[0032] The two adjustment rings 223 are respectively called the upper ring and the lower ring, and the connecting member 225 includes an upper push rod, a connecting rod and a lower push rod arranged in sequence along the first direction. The connecting rod is arranged along the first direction, and the upper push rod is located on the side of the lower push rod close to the upper ring in the first direction. The two ends of the upper push rod are respectively rotatably connected to the upper ring and one end of the connecting rod, and the two ends of the lower push rod are respectively rotatably connected to the lower ring and the other end of the connecting rod.

[0033] Furthermore, a limiting ring 226 is provided on the active rod 221, and a plurality of limiting rods are evenly distributed on the limiting ring 226 around the first direction. The plurality of connecting rods are arranged in one-to-one correspondence with the plurality of limiting rods. The limiting rods and the corresponding connecting rods are connected through a first elastic member 227. The first elastic member 227 is arranged along the second direction, and the first elastic member 227 is a spring.

[0034] Specifically, eight connecting members 225 are provided.

[0035] This embodiment provides two movable rings 224 and multiple connecting members 225. When the diameter of the sealing ring 300, which has high hardness and low elasticity, is expanded, the sealing ring 300 will squeeze the connecting rod through the housing 222, causing the connecting rod to move toward the active rod 221. When the connecting rod moves toward the active rod 221, the upper and lower push rods can force the two movable rings 224 to move away from each other in the first direction. The two movable rings 224 will respectively force the upper and lower rings to move away from each other in the first direction, and the active rod 221 can enable the upper and lower rings to rotate about their respective axes. In other words, the action of the transmission member can cause the two adjustment rings 223 to rotate about their respective axes. When the sealing ring 300 squeezes the connecting rod, the first elastic member 227 can limit the movement of the connecting rod, allowing the connecting rod to move in the second direction.

[0036] In this embodiment, the assembly mechanism 200 further includes a fixed disk 240 , which is fixedly installed in the connecting cylinder 100 and coaxial with the rotating disk 210 . The fixed disk 240 is located on a side of the rotating disk 210 close to the housing 222 in the first direction.

[0037] Four driving grooves 211 are provided on the rotating disk 210, and the four driving grooves 211 are evenly distributed around the first direction on the rotating disk 210. The driving grooves 211 are inclined. Four sliding grooves 241 are provided on the fixed disk 240, and the four sliding grooves 241 are evenly distributed around the first direction on the fixed disk 240. The sliding grooves 241 are set along the second direction.

[0038] The active rod 221, the drive slot 211, and the sliding slot 241 are arranged in a one-to-one correspondence. The projections of the drive slot 211 and the corresponding sliding slot 241 in the first direction are angled and non-perpendicular to each other. The active rod 221 passes through the corresponding drive slot 211 and sliding slot 241 in sequence along the first direction, and the sliding slot 241 can restrict the active rod 221 from rotating about its own axis.

[0039] Specifically, a waist-shaped slider is provided on the active rod 221, and the sliding groove 241 is a waist-shaped groove. The waist-shaped slider is slidably installed in the sliding groove 241, so that the sliding groove 241 can limit the active rod 221 from rotating around its own axis.

[0040] In this embodiment, a fixed disk 240 is provided. When the rotating disk 210 rotates around its own axis, the driving slot 211 will apply a component force along the second direction to the corresponding active rod 221, thereby enabling the active rod 221 to slide along the second direction in the corresponding sliding slot 241.

[0041] In this embodiment, the fixed disk 240 is provided with four synchronization slots 242, which are evenly spaced about the first direction. The synchronization slots 242 are arranged along the second direction. The four synchronization slots 242 correspond to four matching rods 230, and each matching rod 230 passes through its corresponding synchronization slot 242 along the first direction. The matching rods 230 are connected to corresponding adjustment rings 223 arranged about the first direction via connecting rods 250. The connecting rods 250 are telescopic rods, and the adjustment rings 223 rotate about their own axes, thereby causing the matching rods 230 to move in the second direction away from the rotation axis of the rotating disk 210 via the connecting rods 250.

[0042] Specifically, the mating rod 230 includes a main rod and a first follower cylinder. The main rod is arranged along the first direction and passes through the corresponding synchronous groove 242. The first follower cylinder is matched with the main rod keyway. The connecting rod 250 connects the first follower cylinder and one of the adjustment rings 223.

[0043] In this embodiment, by providing the synchronous groove 242, when the rotating disk 210 rotates around its own axis and causes the active rod 221 to move outward along the second direction on the rotating disk 210, and if the sealing ring 300 cannot cause the connecting rod to move toward the side close to the active rod 221, the adjusting ring 223 will only move synchronously with the active rod 221, and the movement of the adjusting ring 223 will drive the matching rod 230 to move through the connecting rod 250, that is, see the attached Figure 3 As shown, when the adjustment ring 223 moves only along the second direction, the movement of the adjustment ring 223 will extend the connecting rod 250 and pull the matching rod 230 to move synchronously in the synchronization groove 242, so that the square formed by the four adjustment parts 220 and the four matching rods 230 is proportionally expanded.

[0044] If the sealing ring 300 can cause the connecting rod to move toward the side close to the active rod 221, the connecting rod will cause the two adjusting rings 223 to move away from each other in the first direction through the moving ring 224, and cause the two adjusting rings 223 to rotate around their own axes. As a result, when the adjusting rings 223 rotate, they will pull the matching rod 230 through the connecting rod 250 connected to them to move further outward in the synchronous groove 242, and the connecting rod 250 will also be synchronously telescopically adjusted, and the square enclosed by the four adjusting parts 220 and the four matching rods 230 will be transformed into an octagon. See the attached Figure 5 shown.

[0045] In another possible embodiment, two connecting rods 250 are provided. The two expansion assemblies disposed adjacent to any one of the mating rods 230 in the first direction are referred to as a forward expansion assembly and a reverse expansion assembly, respectively. One of the connecting rods 250 connected to the mating rod 230 is connected to the upper ring of the forward expansion assembly, while the other connecting rod 250 connected to the mating rod 230 is connected to the lower ring of the reverse expansion assembly. A spiral protrusion is provided on the active rod 221, and spiral grooves are provided on the inner circumferential surfaces of the two adjustment rings 223. The spiral directions of the spiral grooves on the upper and lower rings are opposite. Rotation of the upper and lower rings about their respective axes can, through the connecting rods 250, cause the mating rod 230 to move in the second direction away from the rotation axis of the rotating disk 210.

[0046] The mating rod 230 includes a main rod, a first follower cylinder, and a second follower cylinder. The main rod is arranged along a first direction and passes through a corresponding synchronization slot 242. The first follower cylinder and the second follower cylinder are arranged sequentially along the first direction on the main rod and engage with the main rod keyway, thereby enabling the first and second follower cylinders to move relative to the main rod in the first direction and rotate synchronously with the main rod. One connecting rod 250 connects the upper ring of the forward expansion assembly and the first follower cylinder, while the other connecting rod 250 connects the lower ring of the reverse expansion assembly and the second follower cylinder.

[0047] In this embodiment, two connecting rods 250 are provided, so that each engaging rod 230 can be driven to move by the two connecting rods 250 .

[0048] In this embodiment, a rubber sealing ring quick assembly device further includes a manipulator 400, a connecting cylinder 100 is fixedly mounted on the manipulator 400, an assembly space is defined between the four expansion components, and a component 500 to be installed is inserted into the assembly space.

[0049] After reducing the outer diameters of the four expansion components, the robot 400 controls the movement of the assembly mechanism 200, allowing the four expansion components to be inserted into the inner ring of the sealing ring 300. The sealing ring 300 is positioned within the expansion component housing 222. After the expansion is complete, the component to be mounted 500 is inserted into the assembly space using an external fixture.

[0050] Specifically, a motor is provided in the connecting cylinder 100, and a gear is fixedly provided at the output end of the motor. A gear ring is provided on the outer peripheral wall surface of the rotating disk 210 around the first direction, and the gear is engaged with the gear ring. When in use, the motor is started to drive the gear to rotate, and the rotation of the gear will drive the gear ring to rotate, thereby enabling the rotating disk 210 to rotate around its own axis.

[0051] In this embodiment, the assembly mechanism 200 further includes a squeeze plate 260 and a plurality of squeeze rods 270. The squeeze plate 260 is mounted on the fixed plate 240 via a second elastic member 261. The second elastic member 261 is arranged along a first direction and is a spring. The squeeze plate 260 is movable relative to the fixed plate 240 in the first direction. The plurality of squeeze rods 270 are evenly distributed along the first direction on the squeeze plate 260, and the squeeze rods 270 are located on the side of the squeeze plate 260 that is closest to the housing 222 in the first direction. When the squeeze plate 260 moves relative to the fixed plate 240 in the first direction, the ends of the squeeze rods 270 that are closer to the sealing ring 300 in the first direction can abut against the sealing ring 300, causing the sealing ring 300 to disengage from the housing 222 and the mating rods 230, allowing the sealing ring 300 to be assembled onto the component 500 to be mounted.

[0052] Furthermore, the rotating disk 210 is provided with a plurality of follower slots 212, which are evenly distributed along a first direction and arranged at an angle. The fixed disk 240 is provided with a plurality of movable slots 243, which are evenly distributed along the first direction and arranged along a second direction. The extrusion rods 270, the follower slots 212, and the movable slots 243 are provided in a one-to-one correspondence. The projections of the follower slots 212 and the corresponding movable slots 243 in the first direction are at an angle and are not perpendicular to each other. The extrusion rods 270 sequentially pass through the corresponding follower slots 212 and movable slots 243 along the first direction. When the rotating disk 210 rotates about its own axis, the follower slots 212 exert a force component along the second direction on the corresponding extrusion rods 270, thereby enabling the extrusion rods 270 to slide within the corresponding movable slots 243 along the second direction.

[0053] Specifically, four follower slots 212, four movable slots 243, and four extrusion rods 270 are each provided. A hydraulic telescopic cylinder is disposed within the connecting tube 100, and the extrusion plate 260 is mounted at the output end of the hydraulic telescopic cylinder, enabling the extrusion plate 260 to move in the first direction relative to the fixed plate 240. After the diameter expansion is completed, the hydraulic telescopic cylinder is activated, driving the extrusion plate 260 to move in the first direction relative to the fixed plate 240. This allows the end of the extrusion rod 270 proximate to the sealing ring 300 in the first direction to abut against the sealing ring 300, thereby disengaging the sealing ring 300 from the housing 222 and the mating rod 230, allowing the sealing ring 300 to be assembled onto the component 500 to be mounted.

[0054] In combination with the above embodiment, the specific working process is as follows: When in use, the motor is started first, and the motor starts to drive the gear to rotate, and the rotation of the gear drives the gear ring to rotate, thereby enabling the rotating disk 210 to rotate around its own axis.

[0055] When the rotating disk 210 rotates about its own axis, the driving slot 211 on the rotating disk 210 applies a component of force in the second direction to the corresponding active rod 221, thereby enabling the active rod 221 to slide in the second direction within the sliding slot 241 on the corresponding fixed disk 240. Furthermore, the following slot 212 on the rotating disk 210 applies a component of force in the second direction to the corresponding extrusion rod 270, thereby enabling the extrusion rod 270 to slide in the second direction within the moving slot 243 on the corresponding fixed disk 240.

[0056] Simultaneously, the movement of active rod 221 drives the synchronous movement of the transmission member, housing 222, and two adjustment rings 223. Furthermore, the movement of adjustment ring 223 drives the mating rod 230 via connecting rod 250. In other words, the rotation of rotating disk 210 about its own axis causes the entire expansion assembly to move inward in the second direction on rotating disk 210, reducing the outer diameters of the four expansion assemblies and enabling them to mate with the sealing ring 300 in its natural state. After the outer diameters of the four expansion assemblies are reduced, the assembly mechanism 200 is controlled by the manipulator 400 to move, allowing the four expansion assemblies to be inserted into the inner ring of the sealing ring 300. The sealing ring 300 is positioned within the expansion assembly's housing 222. After the expansion is complete, the component to be mounted 500 is inserted into the assembly space using an external fixture.

[0057] The motor is then driven to reverse, allowing the rotating disk 210 to rotate around its own axis, and driving the expansion assembly as a whole to move outward along the second direction on the rotating disk 210, so that the outer ring diameters of the four expansion assemblies become larger, and the expansion assembly is used to synchronously expand the diameter of the sealing ring 300.

[0058] In this process, when the diameter of the sealing ring 300 with low hardness and good elasticity is expanded, the sealing ring 300 is more likely to deform. When the diameter is expanded, the force exerted by the sealing ring 300 on the transmission member through the housing 222 is small, and the sealing ring 300 will not drive the transmission member to move. At this time, the two adjusting rings 223 remain stationary and will not cause the matching rod 230 to move further outward in the second direction. Therefore, when the rotating disk 210 rotates around its own axis, the adjusting ring 223 will only move synchronously with the active rod 221, and the movement of the adjusting ring 223 will drive the matching rod 230 to move through the connecting rod 250, that is, see the attached Figure 3 As shown, when the adjusting ring 223 moves only in the second direction, the movement of the adjusting ring 223 will cause the connecting rod 250 to extend and pull the matching rod 230 to move synchronously in the synchronous groove 242, so that the square formed by the four adjusting parts 220 and the four matching rods 230 will be proportionally expanded, keeping the square structure unchanged, and driving the sealing ring 300 to expand synchronously. Figure 3 and attached Figure 4The radius of the inscribed circle of the expanded sealing ring 300 is a preset value R1, which is the radius required for the sealing ring 300 to be assembled. The side length of the quadrilateral in which the expanded sealing ring 300 is located is X.

[0059] When the diameter of the sealing ring 300 with high hardness and poor elasticity is expanded, the sealing ring 300 is not easy to deform. Therefore, when the diameter of the sealing ring 300 is expanded, the force of the sealing ring 300 squeezing the outer shell 222 is greater, and the sealing ring 300 will squeeze the connecting rod through the outer shell 222, so that the connecting rod moves toward the side close to the active rod 221. When the connecting rod moves toward the side close to the active rod 221, the two moving rings 224 can be urged to move away from each other in the first direction through the upper push rod and the lower push rod, and the two moving rings 224 will respectively urge the upper ring and the lower ring to move away from each other in the first direction, and through the active rod 221, the upper ring and the lower ring can respectively rotate around their own axes.

[0060] As a result, when the adjusting ring 223 rotates, the connecting rod 250 connected thereto pulls the matching rod 230 to move further outward in the synchronization groove 242, and the connecting rod 250 also synchronously adjusts and retracts, causing the matching rod 230 to move further outward in the second direction. As the rotating disk 210 rotates about its own axis, the diameter expansion assembly will expand as a whole and be pushed further into shape by the matching rod 230, causing the square formed by the four adjusting portions 220 and the four matching rods 230 to gradually change into an octagon. See the attached diagram. Figure 5 and attached Figure 6 As shown, the radius of the inscribed circle of the expanded sealing ring 300 is a preset value R1, and the side length of the octagon in which the expanded sealing ring 300 is located is Y. Furthermore, calculations show that 4X is less than 8Y. This means that when the sealing ring 300, which has high hardness and low elasticity, is expanded, the square enclosed by the four adjustment portions 220 and the four mating rods 230 becomes an octagon. This allows the expanded sealing ring 300 to be assembled with relatively less overall deformation (compared to when it becomes a quadrilateral), thereby minimizing excessive deformation of the sealing ring 300 during expansion and extending its service life.

[0061] After the diameter expansion is completed, the hydraulic telescopic cylinder is started to drive the extrusion plate 260 to move in the first direction relative to the fixed plate 240, so that the end of the extrusion rod 270 close to the sealing ring 300 along the first direction can abut against the sealing ring 300, and promote the sealing ring 300 to separate from the outer shell 222 and the matching rod 230, so that the sealing ring 300 can be assembled on the part to be installed 500.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
