Description

Technical Field

[0001] This invention relates to the field of sealing ring assembly, and more particularly to a sealing ring assembly tooling. Background Technology

[0002] A sealing ring is a rubber product that typically needs to be installed in conjunction with a workpiece to be sealed. However, currently, sealing rings are usually assembled manually, which is difficult and inefficient. Therefore, for a sealing ring kit, the difficulty and inefficiency of manually assembling the sealing rings onto the workpiece is a problem we need to solve. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a sealing ring assembly tooling with a simple structure, reduced assembly difficulties and effectively improved assembly efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a sealing ring assembly tooling, comprising a frame having a slotted accommodating part, a self-retracting mechanism rotatably mounted on the frame, a lifting mechanism slidably mounted on the frame, and a drive mechanism hinged between the self-retracting mechanism and the lifting mechanism, wherein the drive mechanism can both rotate and slide; the drive mechanism, when slid clockwise in the horizontal direction, can drive the self-retracting mechanism to rotate clockwise in the horizontal direction, and the self-retracting mechanism is in a retracted state, with the sealing ring being secured thereon and in a retracted state; the drive mechanism, when slid counterclockwise in the horizontal direction, can drive the self-retracting mechanism to rotate counterclockwise in the horizontal direction, and both the self-retracting mechanism and the sealing ring are in an extended state. Once the workpiece is placed into the receiving slot, the drive mechanism is slid clockwise again in the horizontal direction. This causes the self-retracting mechanism to rotate clockwise in the horizontal direction, and both the self-retracting mechanism and the sealing ring are in a retracted state again. Rotating the drive mechanism clockwise in the vertical direction causes the lifting mechanism to slide in the vertical direction, and the lifting mechanism can insert the sealing ring into the workpiece to complete the assembly. Rotating the drive mechanism counterclockwise in the vertical direction causes the lifting mechanism to slide down in the vertical direction to return to the initial state. Sliding the drive mechanism counterclockwise again in the horizontal direction causes the self-retracting mechanism to rotate counterclockwise in the horizontal direction, and the self-retracting mechanism is in an extended state. The workpiece with the sealing ring can then be removed from the receiving slot.

[0005] The beneficial effect of the sealing ring assembly tooling of the present invention is that when a worker manually places the workpiece into the receiving slot, sliding the drive mechanism clockwise in the horizontal direction causes the self-retracting mechanism to rotate clockwise in the horizontal direction, and the self-retracting mechanism is in a retracted state. The worker then manually places the sealing ring onto the self-retracting mechanism, and the sealing ring is also in a retracted state. Sliding the drive mechanism counterclockwise in the horizontal direction causes the self-retracting mechanism to rotate counterclockwise in the horizontal direction, and both the self-retracting mechanism and the sealing ring are in an extended state. Sliding the drive mechanism clockwise again in the horizontal direction causes the self-retracting mechanism to rotate clockwise in the horizontal direction, and both the self-retracting mechanism and the sealing ring are again in a retracted state. Then, rotating the drive mechanism clockwise vertically causes the lifting mechanism to slide vertically, allowing it to engage the sealing ring with the workpiece and complete the assembly. Rotating the lifting mechanism counterclockwise vertically causes it to slide downwards vertically to return to its initial state. Next, rotating the drive mechanism counterclockwise horizontally causes the self-retracting mechanism to rotate counterclockwise horizontally, extending it to its extended position. This allows a person to remove the workpiece with the sealing ring attached from the receiving slot, completing one assembly cycle. This sealing ring assembly fixture has a simple structure, reduces assembly difficulty, and effectively improves assembly efficiency.

[0006] As a further improvement of the present invention, the self-retracting mechanism includes a limiting ring plate, a retracting ring plate, and multiple sets of sliding components. The limiting ring plate is disposed above the retracting ring plate and has multiple strip-shaped holes evenly arranged on the limiting ring plate. The retracting ring plate is rotatably disposed above the frame and has multiple inclined through holes evenly arranged on the retracting ring plate. The retracting ring plate can also be hinged to the handle on the drive mechanism through a connecting seat. Each set of sliding components includes a fixed slide rail inclinedly disposed on the frame, a sliding seat with a slot slidably disposed on the fixed slide rail, and a sliding pin disposed on the sliding seat. Each sliding pin can pass through the inclined through hole and the strip-shaped hole in sequence and can slide on them. Slide the handle clockwise along the horizontal direction, causing the retractable ring plate and the limiting ring plate to rotate clockwise along the horizontal direction. Since each sliding pin can pass through the inclined through hole and the strip hole in sequence and slide on them, the inclined through hole and the strip hole will slide clockwise. That is, the sliding pin slides clockwise in the inclined through hole and slides close to the receiving slot in the strip hole. Therefore, it will drive the sliding pin and the sliding seat to slide close to the receiving slot. The inner ring formed between multiple sliding seats is the retractable area. At this time, the retractable area becomes smaller and is in a contracted state. A person can lock the sealing ring on multiple slots and the sealing ring is also in a contracted state; the reverse is also true.

[0007] As a further improvement of the present invention, the limiting ring plate, the take-up and release ring plate, and the receiving slot are on the same axis. Multiple fixed slide rails are arranged in a ring around the receiving slot. Each fixed slide rail is equipped with a slide rod, and each slide rod is located below the take-up and release ring plate. Each sliding seat is sleeved on the slide rod and can slide on it. The slide rod enables the sliding seat and sliding pin to slide.

[0008] As a further improvement of the present invention, a connecting seat is disposed on the take-up and release ring plate, and a connecting pin is provided on the connecting seat. The handle is sleeved on the connecting pin and can rotate about the connecting pin as a central axis. The connecting seat and the connecting pin enable the handle to be hinged to the take-up and release ring plate. The handle can both rotate and slide. When the handle is slid clockwise in the horizontal direction, it will cause the take-up and release ring plate to rotate clockwise in the horizontal direction.

[0009] As a further improvement of the present invention, each fixed slide rail is provided with a first clearance groove, and each sliding seat is provided with a connected second clearance groove and a retaining groove, with each second clearance groove located below the retaining groove. The first and second clearance grooves in the same group are at the same level and can form a rotation area between them. The take-up and release ring plate is rotatably arranged on multiple rotation areas. A person can lock the sealing ring into multiple retaining grooves, and the take-up and release ring plate is rotatably arranged on multiple rotation areas with the sealing ring located in the inner ring of the take-up and release ring plate.

[0010] As a further improvement of the present invention, each sliding seat is an L-shaped structure, each second clearance groove is provided on the horizontal plate of the sliding seat, and each slot is provided on the vertical plate of the sliding seat.

[0011] As a further improvement of the present invention, the lifting mechanism includes a lifting ring plate and multiple sets of lifting components. The lifting ring plate is sleeved under the frame and can slide. Each set of lifting components includes a lifting column and a lifting rod. Each lifting column is mounted on the lifting ring plate, and the free ends of some lifting columns can pass through bushings on the frame and engage with some lifting rods. The free ends of the remaining lifting columns can pass through clearance holes on the frame and engage with the remaining lifting rods. Any lifting column can also be hinged to the arm on the drive mechanism via a connecting shaft. The free end of each lifting rod is located in the inner ring of the retracting ring plate of the self-retracting mechanism. Rotating the arm clockwise in the vertical direction can pull one of the lifting columns hinged to the arm to slide clockwise (i.e., slide upwards), causing the lifting ring plate, the remaining lifting columns, and all lifting rods to slide counterclockwise. All lifting rods contact the sealing rings locked in multiple slots and can push them onto the workpiece. Conversely, the arm returns to its initial state.

[0012] As a further improvement of the present invention, a connecting shaft is provided on any one of the lifting columns, and the boom is sleeved on the connecting shaft and can rotate about the connecting shaft as the central axis. The connection shaft enables any one of the lifting columns to be hinged to the boom.

[0013] As a further improvement of the present invention, the drive mechanism includes a frame arm and a handle. The middle part of the frame arm is rotatably disposed below the frame, and one end of the frame arm is hinged to any one of the lifting columns on the lifting mechanism, while the other end is provided with a limit frame. One end of the handle is rotatably disposed on the take-up and release ring plate on the take-up and release mechanism, and the other end can pass through the limit frame. Sliding the handle clockwise in the horizontal direction causes the middle part of the handle to slide clockwise in the horizontal direction within the inner frame of the limit frame, driving the take-up and release ring plate and the limit ring plate to rotate clockwise in the horizontal direction; the reverse is also true. Rotating the handle clockwise in the vertical direction causes the middle part of the handle to rotate clockwise in the inner frame of the limit frame, pressing against the frame arm, thereby pulling the lifting column hinged to the frame arm to slide clockwise (that is, slide upwards).

[0014] As a further improvement of the present invention, the frame includes a lockable frame plate and a frame base with a receiving slot formed between them, a self-retracting mechanism is rotatably mounted on the frame plate, a lifting mechanism is slidably mounted on the frame plate, and the middle part of the drive mechanism is rotatably mounted on the frame plate with one end of the drive mechanism hinged to the self-retracting mechanism and the other end hinged to the lifting mechanism.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0026] See appendix Figure 1-5 As shown, this embodiment of a sealing ring assembly tooling includes a frame with a slotted opening, a self-retracting mechanism 3 rotatably mounted on the frame, a lifting mechanism slidably mounted on the frame, and a drive mechanism 5 hinged between the self-retracting mechanism 3 and the lifting mechanism, the drive mechanism 5 being both rotatable and slidable. Sliding the drive mechanism 5 clockwise in the horizontal direction causes the self-retracting mechanism 3 to rotate clockwise in the horizontal direction, and the self-retracting mechanism 3 is in a retracted state, with the sealing ring caught on it and also in a retracted state. Sliding the drive mechanism 5 counterclockwise in the horizontal direction causes the self-retracting mechanism 3 to rotate counterclockwise in the horizontal direction, and both the self-retracting mechanism 3 and the sealing ring are in an extended state. The workpiece is then placed... The slot is accommodating. Sliding the drive mechanism 5 clockwise along the horizontal direction again causes the self-retracting mechanism 3 to rotate clockwise along the horizontal direction, and both the self-retracting mechanism 3 and the sealing ring are in a retracted state again. Rotating the drive mechanism 5 clockwise along the vertical direction causes the lifting mechanism to slide vertically, and the lifting mechanism can insert the sealing ring into the workpiece to complete the assembly. Rotating the drive mechanism 5 counterclockwise along the vertical direction causes the lifting mechanism to slide downwards vertically to return to its initial state. Sliding the drive mechanism 5 counterclockwise along the horizontal direction again causes the self-retracting mechanism 3 to rotate counterclockwise along the horizontal direction, and the self-retracting mechanism 3 is in an extended state. The workpiece with the sealing ring assembled can be removed from the slot.

[0027] The self-retracting mechanism 3 of this embodiment includes a limiting ring plate 31, a retracting ring plate 32, and multiple sets of sliding components 33. The limiting ring plate 31 is disposed above the retracting ring plate 32 and has multiple strip holes 311 evenly arranged on it. The retracting ring plate 32 is rotatably disposed above the frame and has multiple inclined through holes 321 evenly arranged on it. The retracting ring plate 32 can also be hinged to the handle 52 on the drive mechanism 5 through the connecting seat 10. Each set of sliding components 33 includes a fixed slide rail 331 inclinedly disposed on the frame, a sliding seat 332 slidably disposed on the fixed slide rail 331 and having a slot 6, and a sliding pin 333 disposed on the sliding seat 332. Each sliding pin 333 can pass through the inclined through hole 321 and the strip hole 311 in sequence and can slide on them. Sliding the handle 52 clockwise along the horizontal direction will cause the retracting ring plate 32 and the limiting ring plate 31 to rotate clockwise along the horizontal direction. Since each sliding pin 333 can pass through the inclined through hole 321 and the strip hole 311 in sequence and can slide on them, the inclined through hole 321 and the strip hole 311 will slide clockwise. That is, the sliding pin 333 slides clockwise in the inclined through hole 321 and slides close to the receiving slot in the strip hole 311. Therefore, it will drive the sliding pin 333 and the sliding seat 332 to slide close to the receiving slot. The inner ring formed between the multiple sliding seats 332 is the retracting area. At this time, the retracting area becomes smaller and is in a contracted state. A person can put the sealing ring on the multiple slots 6 and the sealing ring is also in a contracted state; the reverse is the same.

[0028] In this embodiment, the limiting ring plate 31, the retracting ring plate 32, and the receiving slot are on the same axis. Multiple fixed slide rails 331 are arranged in a ring around the receiving slot. Each fixed slide rail 331 is equipped with a slide rod 8, and each slide rod 8 is located below the retracting ring plate 32. Each sliding seat 332 is sleeved on the slide rod 8 and can slide on it. The slide rod 8 enables the sliding seat 332 and the sliding pin 333 to slide.

[0029] In this embodiment, the connecting seat 10 is disposed on the take-up and release ring plate 32, and a connecting pin is provided on the connecting seat 10. The handle 52 is sleeved on the connecting pin and can rotate about the connecting pin as the central axis. The connecting seat 10 and the connecting pin enable the handle 52 to be hinged to the take-up and release ring plate 32. The handle 52 can both rotate and slide. When the handle 52 is slid clockwise in the horizontal direction, it will cause the take-up and release ring plate 32 to rotate clockwise in the horizontal direction.

[0030] In this embodiment, each fixed slide rail 331 is provided with a first clearance groove 9, and each sliding seat 332 is provided with a connected second clearance groove 7 and a retaining groove 6, with each second clearance groove 7 located below the retaining groove 6. The first clearance groove 9 and the second clearance groove 7 in the same group are at the same level and can form a rotation area between them. The take-up and release ring plate 32 is rotatably disposed on multiple rotation areas. A person can lock the sealing ring into multiple retaining grooves 6, and the take-up and release ring plate 32 is rotatably disposed on multiple rotation areas with the sealing ring located in the inner ring of the take-up and release ring plate 32.

[0031] In this embodiment, each sliding seat 332 has an L-shaped structure, each second clearance groove 7 is provided on the horizontal plate of the sliding seat 332, and each slot 6 is provided on the vertical plate of the sliding seat 332.

[0032] The lifting mechanism of this embodiment includes a lifting ring plate 13 and multiple sets of lifting components 4. The lifting ring plate 13 is sleeved under the frame and can slide. Each set of lifting components 4 includes a lifting column 41 and a lifting rod 42. Each lifting column 41 is set on the lifting ring plate 13. The free ends of some lifting columns 41 can pass through the bushings on the frame and be engaged with some lifting rods 42. The free ends of the remaining lifting columns 41 can pass through the clearance holes on the frame and be engaged with the remaining lifting rods 42. Any lifting column 41 can also be hinged to the arm 51 on the drive mechanism 5 through the connecting shaft 11. The free ends of each lifting rod 42 are located in the inner ring of the retracting ring plate 32 of the self-retracting mechanism 3. Rotating the arm 51 clockwise along the vertical direction pulls one of the lifting columns 41, which is hinged to the arm 51, to slide clockwise (i.e., upward). This causes the lifting ring plate 13, the remaining lifting columns 41, and all the lifting rods 42 to slide counterclockwise. All the lifting rods 42 then contact the sealing rings that are locked in the multiple slots 6, pushing them onto the workpiece. Conversely, rotating the arm 51 clockwise returns it to its initial state.

[0033] In this embodiment, a connecting shaft 11 is provided on any one of the lifting columns 41, and the frame arm 51 is sleeved on the connecting shaft 11 and can rotate about the connecting shaft 11 as the central axis. The connection shaft 11 enables any one of the lifting columns 41 to be hinged to the frame arm 51.

[0034] The drive mechanism 5 in this embodiment includes a support arm 51 and a handle 52. The middle part of the support arm 51 is rotatably disposed below the frame, and one end of the support arm 51 is hinged to any one of the lifting columns 41 on the lifting mechanism. The other end is provided with a limit frame 12. One end of the handle 52 is rotatably disposed on the take-up and release ring plate 32 on the take-up and release mechanism 3, and the other end can pass through the limit frame 12. Sliding the handle 52 clockwise in the horizontal direction causes the middle part of the handle 52 to slide clockwise in the horizontal direction within the inner frame of the limit frame 12, driving the take-up and release ring plate 32 and the limit ring plate 31 to rotate clockwise in the horizontal direction; the reverse is also true. Rotating the handle 52 clockwise in the vertical direction causes the middle part of the handle 52 to rotate clockwise in the inner frame of the limit frame 12, pressing the support arm 51 together, thereby pulling the lifting column 41 hinged to the support arm 51 to slide clockwise (that is, slide upward).

[0035] The frame in this embodiment includes a lockable frame plate 1 and a frame base 2, with a receiving slot formed between them. A self-retracting mechanism 3 is rotatably mounted on the frame plate 1, a lifting mechanism is slidably mounted on the frame plate 1, and a drive mechanism 5 is rotatably mounted on the frame plate 1 at its center, with one end of the drive mechanism 5 hinged to the self-retracting mechanism 3 and the other end hinged to the lifting mechanism. (Reference) Figure 1 It can be seen that the frame plate 1 is also equipped with a handle for easy movement; the retractable ring plate 32 is rotatably set above the frame plate 1, the fixed slide rail 331 is inclinedly set above the frame plate 1, the lifting column 41 is slidably set on the frame plate 1 and the lifting ring plate 13 is sleeved on the frame base 2 and can slide, and the middle part of the frame arm 51 is rotatably set below the frame plate 1.

[0036] In the implementation process of this embodiment, the handle 52 is slid clockwise along the horizontal direction. The middle part of the handle 52 will slide clockwise within the inner frame of the limiting frame 12, causing the retractable ring plate 32 and the limiting ring plate 31 to rotate clockwise along the horizontal direction. Since each sliding pin 333 can pass through the inclined through hole 321 and the strip hole 311 in sequence and can slide on them, the inclined through hole 321 and the strip hole 311 will slide clockwise. That is, the sliding pin 333 slides clockwise in the inclined through hole 321 and slides close to the receiving slot in the strip hole 311. Therefore, it will drive the sliding pin 333 and the sliding seat 332 to slide close to the receiving slot. The inner ring formed between the multiple sliding seats 332 is the retractable area. At this time, the retractable area becomes smaller and is in a contracted state. A person can put the sealing ring on the multiple slots 6 and the sealing ring is also in a contracted state. Slide the handle 52 counterclockwise along the horizontal direction. The middle part of the handle 52 will slide counterclockwise along the horizontal direction within the inner frame of the limiting frame 12, causing the take-up and release ring plate 32 and the limiting ring plate 31 to rotate counterclockwise along the horizontal direction. At this time, the take-up and release area becomes larger and is in an extended state, and the sealing ring is also in an extended state. The workpiece is manually placed into the receiving slot.

[0037] Slide handle 52 clockwise again in the horizontal direction, the retraction area shrinks, and the sealing ring is in the contracted state again. Rotate handle 52 clockwise in the vertical direction, the middle of handle 52 will be inside the inner frame of the limiting frame 12 and press against the frame arm 51 to rotate clockwise together, thereby pulling a lifting column 41 hinged to the frame arm 51 to rotate clockwise (that is, slide upward), so that the lifting ring plate 13, the other lifting columns 41 and all lifting rods 42 slide upward, and all lifting rods 42 contact the sealing rings stuck on the multiple slots 6 to push them onto the workpiece. Conversely, the same principle applies, and the frame arm 51 returns to the initial state. Slide handle 52 counterclockwise again in the horizontal direction. The middle part of handle 52 will slide counterclockwise in the horizontal direction within the inner frame of the limiting frame 12, causing the take-up and release ring plate 32 and the limiting ring plate 31 to rotate counterclockwise in the horizontal direction. At this time, the take-up and release area becomes larger and is in an extended state, allowing a person to remove the workpiece with the sealing ring assembled from the receiving slot, completing one assembly slot. Reference Figure 1 This shows the sliding range of handle 52, which is also the range of contraction and extension of the retraction area. This type of sealing ring kit has a simple structure, reduces assembly difficulties, and effectively improves assembly efficiency.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention.
