Description

Technical Field

[0001] This utility model relates to the field of adapter assembly technology, and in particular to a sealing ring assembly device. Background Technology

[0002] Fluid flow piping typically requires adapters for connection. To improve the sealing performance at the connection between the fitting and the connector, a sealing ring is usually installed between them. Sealing rings are divided into inner and outer rings. The outer sealing ring is fitted over the fitting and is usually assembled by a support claw. The inner sealing ring is installed in a mounting groove cut into the inner wall of the connector. Inner sealing rings are more difficult to assemble and prone to installation misalignment. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a sealing ring assembly device that can accurately install the sealing ring into the interior of the adapter.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a sealing ring assembly device, comprising:

[0005] The positioning sleeve has a first channel with a diameter smaller than the outer diameter of the sealing ring along the axial direction. One side of the positioning sleeve is provided with a feeding position that can only accommodate one sealing ring. The end of the positioning sleeve away from the feeding position is used to insert an adapter coaxial with the first channel.

[0006] The feeding mechanism includes a guide rod, a push rod, and a top rod that are coaxial with the first channel and sequentially sleeved from the inside to the outside. The guide rod, the top rod, and the push rod can all reciprocate along the axial direction of the first channel. The guide rod can pass through the sealing ring and be inserted into the adapter. The top rod includes a push claw portion near the end of the adapter. The push claw portion abuts against the end face of the sealing ring to compress the sealing ring at the feeding position and push it into the first channel. The end of the push rod can abut against the end face of the sealing ring and push the sealing ring in the first channel into the mounting groove of the adapter.

[0007] The beneficial effects of this utility model are as follows:

[0008] The guide rod guides the sealing ring, and the push rod uses its claws to deform the sealing ring, sending the inner sealing ring into the first channel. The push rod then moves the sealing ring within the first channel, allowing it to return to its original position within the mounting groove due to its own elasticity. This device reduces the assembly difficulty of the sealing ring located inside the connector and improves the assembly efficiency. It features a simple structure, easy manufacturing, and low cost. The coaxial structure significantly improves the coaxiality of the sealing ring during movement, reducing misalignment.

[0009] Furthermore, the guide rod includes a guide rod body and a limiting part. The limiting part includes a first frustum structure. The sealing ring pushed by the push rod can be sleeved on the side of the first frustum structure and restored under the guidance of the first frustum structure to enter the mounting groove of the adapter.

[0010] The diameter of the internal channel of the adapter is smaller than the outer diameter of the sealing ring. Therefore, the sealing ring will undergo slight compression deformation when it is inside the adapter. The limiting part is set as a first frustum structure. When the sealing ring comes into contact with the side of the first frustum structure, it will be guided and the coaxiality of the mounting groove and the sealing ring will be improved.

[0011] Furthermore, the diameter of the large circular surface of the first frustum structure is smaller than the inner diameter of the sealing ring, allowing the limiting part to pass through the sealing ring. During assembly, the mounting groove of the adapter is located between the large circular surface of the first frustum structure and the push rod.

[0012] Furthermore, the push rod also includes a push rod body, and two push claws are provided. The two push claws are symmetrically arranged along the axis of the first channel. Each push claw includes a connecting arm that is fixedly connected to the push rod body. The end of the connecting arm away from the push rod body is provided with a push arm that bends towards the axis, and the push arm abuts against the end face of the sealing ring.

[0013] Furthermore, the push rod has a first guide groove for the push arm portion to be embedded in, and the positioning sleeve has a second guide groove that communicates with the first channel and is for the connecting arm component to be embedded in.

[0014] Furthermore, the end of the first channel near the feeding position has a flared structure, which facilitates the entry of the sealing ring into the first channel. At the same time, the connecting arm can retract under the push of the flared structure and enter the first channel.

[0015] Furthermore, it also includes a drive assembly, which includes a first linear module, a second linear module, and a third linear module. The first linear module is used to drive the guide rod to move, the second linear module is used to drive the top rod and the push rod to move synchronously, and the third linear module is connected to the output end of the second linear module and is used to drive the push rod to move relative to the top rod.

[0016] Furthermore, it also includes a vertical plate fixedly connected to the positioning sleeve, the feeding position is set on the vertical plate, and the driving component and the positioning sleeve are respectively located on both sides of the vertical plate.

[0017] Furthermore, the upright plate has vertical channels that intersect with the loading position. Multiple vertically distributed sealing rings are stored in the vertical channels. Below the vertical channels, there is a cutting plate that can move along the width direction of the upright plate. The cutting plate has a cutting opening that can only accommodate one sealing ring. During the movement, the cutting plate is aligned with the vertical channels and the loading position respectively.

[0018] Furthermore, the upright plate is provided with an air blowing channel that is aligned with and connected to the feeding position. The air blowing channel is located above the cutting plate and can blow the sealing ring in the cutting opening into the feeding position. Attached Figure Description

[0033] 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 making a clearer and more definite definition of the scope of protection of the present invention.

[0034] This utility model discloses a sealing ring assembly device for assembling the internal sealing ring 3 of the adapter 4. See attached drawing. Figure 7 As shown, an installation groove 41 is provided on the inner wall of the adapter 4, and the sealing ring 3 needs to be installed in this installation groove 41.

[0035] See appendix Figure 1 As shown, the sealing ring assembly device includes a positioning sleeve 1 and a pushing mechanism 5. The positioning sleeve 1 is used to position the adapter 4 and the corresponding sealing ring 3, and the pushing mechanism 5 is used to push the sealing ring 3 into the adapter 4 to complete the assembly of the sealing ring 3.

[0036] See appendix Figure 2 As shown, the positioning sleeve 1 has a first channel 11 along the axial direction, and the diameter of the first channel 11 is smaller than the outer diameter of the sealing ring 3. A feeding position 21, which can only accommodate one sealing ring 3, is provided on one side of the positioning sleeve 1. The sealing ring 3 at the feeding position 21 is fed by a feeding mechanism. The end of the positioning sleeve 1 away from the feeding position 21 is used to insert an adapter 4 coaxial with the first channel 11. The channel 42 of the adapter has the same diameter as the first channel 11. When the connector is inserted into the positioning sleeve 1, the connector and the end of the first channel 11 abut against each other and separate from the sealing ring 3.

[0037] See appendix Figure 2 and attached Figure 3As shown, the feeding mechanism 5 includes a guide rod 51, a push rod 53, and a push rod 52 coaxial with the first channel 11. The guide rod 51, push rod 52, and push rod 53 are sequentially sleeved from the inside out, but all three can extend into the adapter 4 through the first channel 11. The guide rod 51, push rod 53, and push rod 52 can all reciprocate along the axial direction of the first channel 11. The guide rod 51 can pass through the sealing ring 3 to guide the sealing ring 3. The push rod 53 includes a push claw portion 532 near the end of the adapter 4. The push claw portion 532 abuts against the end face of the sealing ring 3 to compress and deform the sealing ring 3 at the feeding position 21 and push it into the first channel 11. The end of the push rod 52 can abut against the end face of the sealing ring 3 and push the sealing ring 3 in the first channel 11 into the mounting groove of the adapter 4.

[0038] In this embodiment, the guide rod 51 guides the sealing ring 3, and the push rod 53 uses the push claw part 532 to squeeze and deform the sealing ring 3, sending the inner sealing ring 3 into the first channel 11. The push rod 52 then pushes the sealing ring 3 within the first channel 11 to move, allowing the sealing ring 3 to return to its original position within the mounting groove under its own elastic force after reaching the mounting groove position. This device reduces the assembly difficulty of the sealing ring 3 located inside the connector and improves the assembly efficiency of the sealing ring 3 inside the connector. It features a simple structure, easy manufacturing, and low cost. The coaxial structure greatly improves the coaxiality of the sealing ring 3 during movement, reducing offset.

[0039] In one embodiment, see Appendix Figure 3 As shown, the guide rod 51 includes a guide rod body 511 and a limiting part 512. The limiting part 512 includes a first frustum structure 5121. The limiting part 512 is fixed to the end of the guide rod body 511, and the small circular surface of the first frustum structure 5121 is fixedly connected to the limiting rod body. The sealing ring 3 pushed by the push rod 52 can be fitted onto the side of the first frustum structure 5121 and restored under the guidance of the first frustum structure 5121 to enter the mounting groove of the adapter 4. The diameter of the internal channel of the adapter 4 is smaller than the outer diameter of the sealing ring 3. Therefore, the sealing ring 3 will have slight compression deformation when it is inside the adapter 4. By setting the limiting part 512 as the first frustum structure 5121, the sealing ring 3 will be guided after contacting the side of the first frustum structure 5121, improving the coaxiality of the mounting groove and the sealing ring 3. At the same time, the inclined side of the first frustum structure 5121 allows the sealing ring 3 to gradually restore until the sealing ring 3 is embedded in the mounting groove.

[0040] When feeding material at feeding position 21, the guide rod 51 is located entirely on the side of feeding position 21 away from the positioning sleeve, so as not to interfere with feeding at feeding position 21. After feeding position 21 completes feeding one sealing ring 3, the guide rod 51 passes through the sealing ring 3. The diameter of the large circular surface of the first frustum structure 5121 is smaller than the inner diameter of the sealing ring 3, allowing the limiting part 512 to pass through the sealing ring 3.

[0041] For assembly, please refer to the appendix. Figure 2 As shown, the mounting groove of the adapter 4 is located between the large circular surface of the first frustum structure 5121 and the push rod 52, so that the sealing ring 3 can be embedded into the mounting groove before it reaches the large circular surface of the first frustum structure 5121.

[0042] The limiting part 512 also includes a second frustum structure 5122, the large circular surface of the second frustum structure 5122 being the same size as the large circular surface of the first frustum structure 5121 and mating with it. In this way, when the phase part passes through the sealing ring 3 at the feeding position 21, even if the position of the sealing ring 3 is slightly off, the second frustum structure 5122 can guide the sealing ring 3 to be aligned, thus ensuring the coaxiality of the sealing ring 3 and the limiting rod.

[0043] See appendix Figure 4 As shown, the push rod 53 also includes a push rod body 531, which is sleeved on the push rod 52. Two push claws are provided, symmetrically arranged relative to the axis of the first channel 11. The push claw portion 532 includes a connecting arm 5321 fixedly connected to the push rod body 531. At the end of the connecting arm 5321 away from the push rod body 531, a push arm 5322 bent towards the axis is provided, which abuts against the end face of the sealing ring 3. After the push arm 5322 abuts against the sealing ring 3, it continues to move. Due to the limitation of the positioning sleeve 1, the sealing ring 3 can be bent from the middle position, allowing it to enter the first channel 11, whose size is smaller than its outer diameter.

[0044] See appendix Figure 2 and attached Figure 5 As shown, the end of the first channel 11 near the loading position 21 is a flared structure 13, which facilitates the entry of the sealing ring 3 into the first channel 11. Simultaneously, the connecting arm 5321 forms a spring-loaded structure. Because the maximum distance between the connecting arms 5321 is greater than the outer diameter of the sealing ring 3, which is also greater than the diameter of the first channel 11, the connecting arm 5321 can retract under the push of the flared structure 13 and enter the first channel 11. The contact surface between the push arm 5322 and the sealing ring 3 is an inclined surface corresponding to the flared structure 13. The radial width of the contact surface between the push arm 5322 and the sealing ring 3 is greater than the radial width of the sealing ring 3, allowing the push arm 5322 to deform the sealing ring 3.

[0045] See appendix Figure 3 As shown, the push rod 53 is sleeved on the push rod 52, but the push arm 5322 is bent towards the axial direction. In order to make way for the push arm 5322, the push rod 52 is provided with a first guide groove 521 for the push arm 5322 to be partially embedded. The push arm 5322 moves along the first guide groove 521. At this time, when the push rod 52 and the push rod 53 move relative to each other, the first guide groove 521 guides and makes way for the push arm 5322.

[0046] To make way for the spring arm and guide the movement of the push rod 53, see Appendix. Figure 5 As shown, the positioning sleeve 1 has a second guide groove 12 that communicates with the first channel 11 and allows the connecting arm 5321 component to be embedded.

[0047] See appendix Figure 1 As shown, the sealing ring 3 assembly device also includes a drive assembly 6, which comprises a first linear module 61, a second linear module 62, and a third linear module 63. The first linear module 61 is fixed to the horizontal plate and is used to drive the guide rod 51 to move. The second linear module 62 is used to drive the push rod 53 and the push rod 52 to move synchronously. The third linear module 63 is connected to the output end of the second linear module 62 and is used to drive the push rod 52 to move relative to the push rod 53. The second linear module 62 is fixed on the horizontal plate, and a transverse plate is fixed to its output end. The third linear module 63 and the push rod 53 are fixed on the transverse plate.

[0048] The first linear module 61, the second linear module 62, and the third linear module 63 can all be cylinders.

[0049] A vertical plate 2 is fixed on the horizontal plate, a positioning sleeve is fixed on the vertical plate 2, a feeding position 21 is set on the vertical plate 2, and the driving component 6 and the positioning sleeve are located on both sides of the vertical plate 2 respectively.

[0050] See appendix Figure 6 As shown, the feeding mechanism includes a vertical channel 22 on the upright plate 2 that intersects with the feeding position 21, meaning the vertical channel 22 and the feeding position 21 are not vertically aligned. Multiple vertically distributed sealing rings 3 are stored within the vertical channel 22, and the sealing rings 3 within the vertical channel 22 can be fed via a vibratory feeder. Below the vertical channel 22 is a cutting plate 23 that can move along the width of the upright plate 2. The cutting plate 23 has a cutting opening 231 that can only accommodate one sealing ring 3. During its movement, the cutting plate 23 aligns with both the vertical channel 22 and the feeding position 21.

[0051] When the cutting opening 231 is aligned with the vertical channel 22, the lowest sealing ring 3 in the vertical channel 22 falls into the cutting opening 231. Then the cutting plate 23 moves horizontally until the cutting opening 231 is aligned with the loading position 21, and the sealing ring 3 in the cutting opening 231 falls into the loading position 21.

[0052] Since the sealing ring 3 is relatively light, it may not be able to fall from the cutting opening 231 into the loading position 21 by its own weight. Therefore, an air blowing channel 24 is provided on the upright plate 2, which is aligned with and connected to the loading position 21. The air blowing channel 24 is located above the cutting plate 23 and can blow the sealing ring 3 in the cutting opening 231 into the loading position 21.

[0053] When the device is working, the cutting plate 23 moves a sealing ring 3 in the vertical channel 22 to directly above the loading position 21, and loads the sealing ring 3 to the loading position 21 through the pushing channel. Then, the first linear module 61 drives the limiting rod to pass through the sealing ring 3 to the set position. The adapter 4 is manually inserted into the end of the positioning sleeve 1. At the set position, the large surface of the first frustum structure 5121 of the limiting part 512 is located on the side of the mounting groove away from the sealing ring 3 of the vertical plate 2. The second linear module 62 drives the push rod 52 and the top rod 53 to move synchronously toward the seal. During this process, the end of the push claw of the top rod 53 protrudes from the push rod 52. The push claw first abuts against the end face of the sealing ring 3 at the loading position 21. The sealing ring 3 is squeezed smaller by the push claw and enters the first channel 11. The second linear module 62 stops. Finally, the third linear module 63 pushes the push rod 52 to move relative to the top rod 53. The push rod 52 pushes the sealing ring 3 in the first channel 11 into the channel 42 of the adapter, and abuts against the side of the first frustum structure 5121. Under the guidance of the first frustum structure 5121, the squeezed sealing ring 3 gradually recovers until it is embedded in the mounting groove. At this point, one sealing ring 3 is assembled, and the guide rod 51, top rod 53 and push rod 52 are all reset to await the assembly of the next sealing ring 3.

[0054] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
