DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] An embodiment of a rubber sealing ring quick assembly device of the present invention is as follows Figures 1 to 12 shown.

[0032] A rubber seal ring quick assembly device is used to assemble a seal ring 300, comprising a connecting tube 100 and an assembly mechanism 200. The assembly mechanism 200 comprises a rotating disk 210 and four diameter expansion components. The rotating disk 210 can be rotatably mounted on the connecting tube 100 around its own axis, and the direction of the rotating axis of the rotating disk 210 is referred to as a first direction.

[0033] The four diameter expansion components are evenly distributed around the first direction on the rotating disk 210. The sealing ring 300 is sleeved on the diameter expansion component. The diameter expansion component includes an adjustment portion 220 and a matching rod 230. In the initial state, the four adjustment portions 220 and the four matching rods 230 form a square, and the adjustment portions 220 and the matching rods 230 are arranged in sequence in the rotation direction of the rotating disk 210. In the initial state, the four adjustment portions 220 are respectively located at the four corners of the square. The angle between the matching rod 230 and the corresponding adjustment portion 220 is 45°.

[0034] The adjusting part 220 includes an active rod 221, a transmission member, a housing 222 and two adjusting rings 223. The active rod 221 is arranged along a first direction on the rotating disk 210. The rotating disk 210 rotates around its own axis to cause the active rod 221 to move in a second direction, which is a radial direction of the rotating disk 210.

[0035] The two adjustment rings 223 are arranged in sequence along the first direction on the active rod 221 and connected by a transmission member. The housing 222 is elastic and installed outside the two adjustment rings 223. The transmission member, the housing 222 and the two adjustment rings 223 can all move in the second direction with the active rod 221. The matching rod 230 is arranged along the first direction and can move synchronously with the adjustment ring 223. The sealing ring 300 contacts the housing 222 and the matching rod 230. When the active rod 221 moves along the second direction to the side away from the rotation axis of the rotating disk 210 and can cause the transmission member to move through the sealing ring 300, the movement of the transmission member can cause the two adjustment rings 223 to move away from each other in the first direction and cause the two adjustment rings 223 to rotate around their own axes respectively. The rotation of the adjustment ring 223 around its own axis can cause the matching rod 230 to move in the second direction and change the square enclosed by the four adjustment parts 220 and the four matching rods 230 into an octagon.

[0036] For the convenience of explanation, the side close to the rotation axis of the rotating disk 210 along the second direction is called inner, and the side away from the rotation axis of the rotating disk 210 is called outer.

[0037] When in use, the rotating disk 210 is first driven to rotate around its own axis, so that the active rod 221 moves inward along the second direction on the rotating disk 210. The movement of the active rod 221 will drive the transmission member, the housing 222 and the two adjustment rings 223 to move synchronously, and the movement of the active rod 221 in the second direction can drive the matching rod 230 to move synchronously. That is, the rotation of the rotating disk 210 around its own axis can make the diameter expansion assembly move inward along the second direction on the rotating disk 210 as a whole, so that the outer ring diameters of the four diameter expansion assemblies become smaller and can be adapted to the sealing ring 300 in a natural state, so that the four diameter expansion assemblies can be inserted into the inner ring of the sealing ring 300, and the sealing ring 300 is located at the housing 222 of the diameter expansion assembly.

[0038] Then, the rotating disk 210 is driven to rotate around its own axis, so that the four diameter expansion components move outward along the second direction on the rotating disk 210, so that the outer diameters of the four diameter expansion components become larger, and the diameter expansion components are used to synchronously expand the sealing ring 300.

[0039] 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 of the sealing ring 300 is expanded, the force of squeezing the transmission member through the outer shell 222 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 rotation of the rotating disk 210 around its own axis, the diameter expansion component will be proportionally expanded, and the square structure surrounded by the four adjustment parts 220 and the four matching rods 230 will remain unchanged, and drive the sealing ring 300 to expand synchronously. See the attached Figure 3 and attached Figure 4 The radius of the inscribed circle of the sealing ring 300 after the diameter expansion is a preset value R1, and R1 is the radius required for the sealing ring 300 to complete the assembly. The side length of the quadrilateral where the sealing ring 300 is located after the diameter expansion is X.

[0040] 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 transmission member through the outer shell 222. The transmission member can cause the two adjustment rings 223 to rotate around their own axes respectively, and the rotation of the adjustment ring 223 around its own axis can cause the matching rod 230 to move further outward in the second direction. In the process of the rotating disk 210 rotating around its own axis, the diameter expansion component will be pushed by the matching rod 230 to further deform on the basis of the overall expansion, and the square surrounded by the four adjustment parts 220 and the four matching rods 230 will gradually become an octagon, see the attached Figure 5 and attached Figure 6As shown, the radius of the inscribed circle of the sealing ring 300 after the diameter expansion is a preset value R1, and the side length of the octagon in which the sealing ring 300 is located after the diameter expansion is Y. After determining the radius of the inscribed circle of the sealing ring 300 after the diameter expansion, 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.

[0041] And after calculation, 4X<8Y, that is, when the sealing ring 300 with high hardness and poor elasticity is expanded, the square enclosed by the four adjustment parts 220 and the four matching rods 230 is changed into an octagon, so that the overall deformation of the sealing ring 300 after the expansion is relatively reduced (relative to the transformation into a quadrilateral) while ensuring that the sealing ring 300 can be assembled after the expansion, thereby avoiding excessive deformation of the sealing ring 300 during the expansion as much as possible and extending the service life of the sealing ring 300.

[0042] In this embodiment, the transmission member includes two moving rings 224 and a plurality of connecting members 225. The two moving rings 224 are sequentially arranged on the active rod 221 along the first direction and are rotatably matched with the active rod 221. The two ends of the housing 222 along the first direction are respectively connected to the two moving rings 224. The two moving rings 224 and the two adjusting rings 223 are arranged in a one-to-one correspondence. Each adjusting ring 223 is located on a side of the moving ring 224 corresponding to the moving ring 224 arranged thereto, away from the other moving ring 224 in the first direction. The plurality of connecting members 225 are evenly distributed around the first direction between the two moving rings 224. The active rod 221 is a threaded rod. The two adjusting rings 223 are both sleeved on the active rod 221 and are spirally matched with the active rod 221. The two adjusting rings 223 can move synchronously with the moving ring 224 arranged thereto in the first direction, and can rotate around their own axes relative to the moving ring 224 arranged thereto. 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 axes relative to the corresponding movable ring 224.

[0043] 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.

[0044] Furthermore, a limit ring 226 is provided on the active rod 221, and a plurality of limit rods are evenly distributed on the limit ring 226 around the first direction. The plurality of connecting rods are arranged one by one corresponding to the plurality of limit rods. The limit 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.

[0045] Specifically, eight connecting members 225 are provided.

[0046] In this embodiment, two moving rings 224 and a plurality of connecting members 225 are provided. When the sealing ring 300 with high hardness and poor elasticity is expanded, the sealing ring 300 will squeeze the connecting rod through the housing 222, so that the connecting rod moves to the side close to the active rod 221. When the connecting rod moves to 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 the upper ring and the lower ring can be respectively rotated around their own axes through the active rod 221. That is, the action of the transmission member can cause the two adjustment rings 223 to rotate around their own axes respectively. And when the sealing ring 300 squeezes the connecting rod, the movement of the connecting rod can be limited by the first elastic member 227, so that the connecting rod can move in the second direction.

[0047] In this embodiment, the assembly mechanism 200 further includes a fixed disk 240 , which is fixedly installed in the connecting tube 100 and coaxial with the rotating disk 210 . The fixed disk 240 is located on one side of the rotating disk 210 close to the housing 222 in the first direction.

[0048] The rotating disk 210 is provided with four driving grooves 211, which are evenly distributed around the first direction on the rotating disk 210 and are inclined. The fixed disk 240 is provided with four sliding grooves 241, which are evenly distributed around the first direction on the fixed disk 240 and are arranged along the second direction.

[0049] The active rod 221, the driving groove 211 and the sliding groove 241 are arranged in a one-to-one correspondence. The projections of the driving groove 211 and the sliding groove 241 arranged corresponding thereto in the first direction have an angle, and are not perpendicular to each other. The active rod 221 passes through the driving groove 211 and the sliding groove 241 arranged corresponding thereto in sequence along the first direction, and the sliding groove 241 can limit the active rod 221 from rotating around its own axis.

[0050] 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.

[0051] In this embodiment, a fixed disk 240 is provided. When the rotating disk 210 rotates around its own axis, the driving groove 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 groove 241.

[0052] In this embodiment, four synchronization grooves 242 are formed on the fixed disk 240, and the four synchronization grooves 242 are evenly distributed around the first direction on the fixed disk 240, and the synchronization grooves 242 are arranged along the second direction. The four synchronization grooves 242 are arranged one by one with the four matching rods 230, and each matching rod 230 passes through the synchronization groove 242 correspondingly arranged thereto along the first direction. The matching rod 230 is connected to the adjustment ring 223 correspondingly arranged thereto around the first direction through the connecting rod 250, and the connecting rod 250 is a telescopic rod, and the rotation of the adjustment ring 223 around its own axis can cause the matching rod 230 to move in the second direction to the side away from the rotation axis of the rotating disk 210 through the connecting rod 250.

[0053] Specifically, the matching 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, and the first follower cylinder cooperates with the main rod keyway. The connecting rod 250 connects the first follower cylinder and one of the adjustment rings 223.

[0054] 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 adjusting ring 223 moves only in the second direction, the movement of the adjusting ring 223 will extend the connecting rod 250 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 is proportionally enlarged.

[0055] 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 respectively, so that when the adjusting ring 223 rotates, it will pull the matching rod 230 to move further outward in the synchronous groove 242 through the connecting rod 250 connected thereto, 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 changed into an octagon. Figure 5 shown.

[0056] In another possible embodiment, two connecting rods 250 are provided, and the two expansion assemblies arranged adjacent to any matching rod 230 around the first direction are respectively referred to as the forward expansion assembly and the reverse expansion assembly, one of the connecting rods 250 connected to the matching rod 230 is connected to the upper ring of the forward expansion assembly, and the other connecting rod 250 connected to the matching rod 230 is connected to the lower ring on the reverse expansion assembly. A spiral protrusion is provided on the active rod 221, and spiral grooves are provided on the inner circumferential wall surfaces of the two adjustment rings 223, and the spiral directions of the spiral grooves on the upper ring and the lower ring are opposite, and the upper ring and the lower ring rotate around their own axes respectively, which can cause the matching rod 230 to move in the second direction to the side away from the rotation axis of the rotating disk 210 through the connecting rod 250.

[0057] The mating rod 230 includes a main rod, a first follower cylinder and a second follower cylinder. The main rod is arranged along the first direction and passes through the corresponding synchronous groove 242. The first follower cylinder and the second follower cylinder are arranged on the main rod in sequence along the first direction and cooperate with the main rod keyway, so that the first follower cylinder and the second follower cylinder can move relative to the main rod in the first direction and can rotate synchronously with the main rod. One of the connecting rods 250 connects the upper ring of the forward expansion assembly and the first follower cylinder, and the other connecting rod 250 connects the lower ring of the reverse expansion assembly and the second follower cylinder.

[0058] In this embodiment, two connecting rods 250 are provided, so that each mating rod 230 can be driven to move by the two connecting rods 250 .

[0059] In this embodiment, a rubber sealing ring quick assembly device also includes a manipulator 400, a connecting tube 100 is fixedly mounted on the manipulator 400, an assembly space is defined between four expansion components, and a component 500 to be installed is inserted into the assembly space.

[0060] After the outer diameters of the four diameter-expanding components are reduced, the robot 400 is used to control the assembly mechanism 200 to move so that the four diameter-expanding components can be inserted into the inner ring of the sealing ring 300. The sealing ring 300 is located at the outer shell 222 of the diameter-expanding component. After the diameter expansion is completed, the external fixture is used to insert the component to be installed 500 into the assembly space.

[0061] Specifically, a motor is arranged in the connecting cylinder 100, a gear is fixedly arranged at the output end of the motor, a gear ring is arranged on the outer peripheral wall surface of the rotating disk 210 around the first direction, and the gear is meshed 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.

[0062] In this embodiment, the assembly mechanism 200 further includes a pressing plate 260 and a plurality of pressing rods 270. The pressing plate 260 is mounted on the fixed plate 240 via a second elastic member 261. The second elastic member 261 is arranged along the first direction and is a spring. The pressing plate 260 can move along the first direction relative to the fixed plate 240. The plurality of pressing rods 270 are evenly distributed around the first direction on the pressing plate 260, and the pressing rods 270 are located on a side of the pressing plate 260 close to the housing 222 in the first direction. When the pressing plate 260 moves in the first direction relative to the fixed plate 240, one end of the pressing rod 270 close to the sealing ring 300 in the first direction can abut against the sealing ring 300, and cause the sealing ring 300 to be separated from the housing 222 and the matching rod 230, so that the sealing ring 300 can be assembled to the component 500 to be installed.

[0063] Further, the rotating disk 210 is provided with a plurality of follower grooves 212, which are evenly distributed around the first direction on the rotating disk 210, and the follower grooves 212 are inclined. The fixed disk 240 is provided with a plurality of moving grooves 243, which are evenly distributed around the first direction on the fixed disk 240, and the moving grooves 243 are arranged along the second direction. The extrusion rod 270, the follower groove 212 and the moving groove 243 are arranged one by one, and the projections of the follower groove 212 and the moving groove 243 corresponding thereto in the first direction are at an angle, and are not perpendicular to each other. The extrusion rod 270 passes through the follower groove 212 and the moving groove 243 corresponding thereto in sequence along the first direction. When the rotating disk 210 rotates around its own axis, the follower groove 212 will apply a component force along the second direction to the extrusion rod 270 corresponding thereto, thereby enabling the extrusion rod 270 to slide along the second direction in the moving groove 243 corresponding thereto.

[0064] Specifically, four follower grooves 212, four moving grooves 243, and four extrusion rods 270 are provided. A hydraulic telescopic cylinder is provided in the connecting tube 100, and the extrusion plate 260 is installed at the output end of the hydraulic telescopic cylinder, so that the extrusion plate 260 can move in the first direction relative to the fixed plate 240. 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 the sealing ring 300 is separated from the housing 222 and the matching rod 230, so that the sealing ring 300 can be assembled on the part to be installed 500.

[0065] In combination with the above embodiments, the specific working process is as follows:

[0066] When in use, the motor is started first, and the motor can 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.

[0067] When the rotating disk 210 rotates around its own axis, the driving slot 211 on the rotating disk 210 will apply a component force along the second direction to the corresponding active rod 221, so that the active rod 221 can slide along the second direction in the sliding slot 241 on the corresponding fixed disk 240. And the following slot 212 on the rotating disk 210 will apply a component force along the second direction to the corresponding extrusion rod 270, so that the extrusion rod 270 can slide along the second direction in the moving slot 243 on the corresponding fixed disk 240.

[0068] At the same time, the movement of the active rod 221 will drive the transmission member, the housing 222 and the two adjustment rings 223 to move synchronously, and the movement of the adjustment ring 223 will drive the matching rod 230 to move through the connecting rod 250, that is, the rotation of the rotating disk 210 around its own axis can make the expansion assembly as a whole move inward along the second direction on the rotating disk 210, so that the outer ring diameters of the four expansion assemblies become smaller and can be adapted to the sealing ring 300 in a natural state. After the outer ring diameters of the four expansion assemblies are reduced, the assembly mechanism 200 is controlled by the manipulator 400 to move, so that the four expansion assemblies can be inserted into the inner ring of the sealing ring 300. The sealing ring 300 is located at the housing 222 of the expansion assembly. After the expansion is completed, the external fixture is used to insert the component 500 to be installed into the assembly space.

[0069] Then the driving motor is reversed to allow the rotating disk 210 to rotate around its own axis and drive the expanding assembly as a whole to move outward along the second direction on the rotating disk 210, so that the outer diameters of the four expanding assemblies become larger, and the expanding assembly is used to synchronously expand the sealing ring 300.

[0070] In this process, when the sealing ring 300 with low hardness and good elasticity is expanded, the sealing ring 300 is more likely to deform. When the sealing ring 300 is expanded, the force of squeezing 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 adjustment 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 adjustment ring 223 will only move synchronously with the active rod 221, and the movement of the adjustment ring 223 will drive the matching rod 230 to move through the connecting rod 250, that is, see the attached Figure 3 As shown in FIG. 1 , when the adjusting ring 223 moves only in the second direction, the movement of the adjusting ring 223 will extend the connecting rod 250 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 is proportionally enlarged, the square structure is kept unchanged, and the sealing ring 300 is driven to expand synchronously. Figure 3 and attached Figure 4The radius of the inscribed circle of the sealing ring 300 after the diameter expansion is a preset value R1, and R1 is the radius required for the sealing ring 300 to complete the assembly. The side length of the quadrilateral where the sealing ring 300 is located after the diameter expansion is X.

[0071] 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 to move the connecting rod 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 forced 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 force the upper ring and the lower ring to move away from each other in the first direction, and the upper ring and the lower ring can be rotated around their own axes respectively through the active rod 221.

[0072] As a result, when the adjusting ring 223 rotates, the connecting rod 250 connected thereto will pull the matching rod 230 to move further outward in the synchronous groove 242, and the connecting rod 250 will also be adjusted synchronously to move outward in the second direction. In the process of the rotating disk 210 rotating around its own axis, the diameter expansion component will be pushed and further deformed by the matching rod 230 on the basis of overall expansion, and the square surrounded by the four adjusting parts 220 and the four matching rods 230 will gradually become an octagon, see the attached Figure 5 and attached Figure 6 As shown, the radius of the inscribed circle of the sealing ring 300 after the diameter expansion is the preset value R1, and the side length of the octagon in which the sealing ring 300 after the diameter expansion is located is Y. And after calculation, 4X<8Y, that is, when the diameter of the sealing ring 300 with high hardness and poor elasticity is expanded, the square surrounded by the four adjustment parts 220 and the four matching rods 230 becomes an octagon, so that the overall deformation of the sealing ring 300 after the diameter expansion is relatively reduced (relative to the quadrilateral), while ensuring that the sealing ring 300 can be assembled after the diameter expansion, thereby avoiding the excessive deformation of the sealing ring 300 during the diameter expansion as much as possible, and extending the service life of the sealing ring 300.

[0073] After the 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 cause 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.

[0074] 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 principle of the present invention should be included in the protection scope of the present invention.
