[0041] Before explaining any embodiment of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements described in the following description or shown in the above drawings.

[0042] In this application, the terms "comprise", "include", "have" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0043] In this application, the term "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this application, the character " / " generally indicates that the associated objects before and after are in an "and / or" relationship.

[0044] In this application, the terms "connect", "combine", "couple", "mount" can be direct connection, combination, coupling or mounting, or indirect connection, combination, coupling or mounting. For example, direct connection means that two parts or components are connected together without the need for an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling and can include electrical connection or coupling.

[0045] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use in relation to a particular value, etc. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. Relative terms may refer to a plus or minus a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without the use of a relative term should also be disclosed as a particular value with a tolerance. In addition, when expressing a relative angular positional relationship (such as substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0046] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0047] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0048] Combination Figures 1 to 6 As shown, the support ring device provided in this embodiment can support multiple sealing rings 10 at the same time, so as to reduce the processing cost and improve the processing efficiency. Figure 3 In this embodiment, the direction from left to right is recorded as direction A, the counterclockwise direction is recorded as direction B, and the direction from bottom to top is recorded as direction C.

[0049] Specifically, the support ring device includes a mounting frame 100, a first drive assembly 200 and multiple groups of support ring mechanisms 300; the first drive assembly 200 is fixedly connected to the mounting frame 100, and a driving rack 210 is connected to the first output shaft of the first drive assembly 200; each group of support ring mechanisms 300 includes a transmission gear 310 and a support ring assembly 320 that is transmission-connected to the transmission gear 310, and each transmission gear 310 is meshed with the driving rack 210; when the first drive assembly 200 drives the driving rack 210 to move along the A direction, the corresponding support ring assembly 320 can be driven to open through the transmission gear 310 to open the sealing ring 10 placed on the support ring assembly 320.

[0050] Since the first driving component 200 operates, the support ring component 320 is driven to open, thereby expanding the sealing ring 10 placed on the support ring component 320; therefore, when the sealing ring 10 is installed, not only the speed of expanding the sealing ring 10 can be increased, but also the opening degree of the support ring component 320 can be changed by setting the output value of the first driving component 200 to ensure that the expansion amount of each sealing ring 10 on the support ring component 320 is consistent, thereby avoiding the sealing ring 10 from breaking due to manual operation errors or abnormal conditions of the assembled parts due to improper operation, improving the installation effect of the sealing ring 10, and reducing the probability of the sealing ring 10 being damaged during the expansion and assembly stage, thereby reducing production costs.

[0051] Since multiple groups of support ring assemblies 320 are provided, and each group of support ring assemblies 320 is meshed with the driving rack 210 through the corresponding transmission gear 310; therefore, when the first driving assembly 200 drives the driving rack 210 to move along the A direction, the driving rack 210 can be meshed with multiple transmission gears 310 to drive multiple groups of support ring assemblies 320 to open at the same time, thereby achieving multiple sealing rings 10 being stretched at the same time, so as to further improve the overall processing efficiency.

[0052] In some other embodiments, the transmission mode between the first drive assembly 200 and the plurality of support ring mechanisms 300 can be set as sprocket transmission in addition to gear transmission. Specifically, the component connected to the support ring assembly 320 can be set as a transmission sprocket, and correspondingly, a driving chain is connected to the first output shaft of the first drive assembly 200, and each driving sprocket is connected to the driving chain; when the first drive assembly 200 drives the driving chain to move along the A direction, the corresponding support ring assembly 320 can be driven to open through the transmission sprocket to open the sealing ring 10 placed on the support ring assembly 320.

[0053] Combination Figures 1 to 3 As shown, in some embodiments, four groups of support ring mechanisms 300 may be provided, and the four groups of support ring mechanisms 300 are evenly spaced and connected to the mounting frame 100 along the A direction, and are all connected to the driving rack 210 through corresponding transmission gears 310 .

[0054] Combination Figures 4 to 6 As shown, in some embodiments, the support ring assembly 320 includes a limiting cylinder 321, an opening plate 322, a connecting shaft 323 and a plurality of opening rods 324; corresponding to the plurality of opening rods 324, a plurality of guide grooves 3221 may be arranged on the opening plate 322 along its circumferential intervals, and along the axial direction of the opening plate 322, the plurality of guide grooves 3221 are all arranged to be arc-shaped grooves protruding away from the direction B; the limiting cylinder 321 may be fixedly connected to the mounting frame 100, the first end of the connecting shaft 323 may be fixedly connected to the lower end surface of the opening plate 322, the second end may pass through the limiting cylinder 321 and be fixedly connected to the corresponding transmission gear 310, the first ends of the plurality of opening rods 324 may all pass through the corresponding guide grooves 3221 and be movably connected to the limiting cylinder 321, and the second ends of the plurality of opening rods 324 may be able to synchronously move in the direction away from the axial direction of the opening plate 322 during the rotation of the opening plate 322, so as to cooperate with each other to support the sealing ring 10.

[0055] Specifically, in this embodiment, there are eight expansion rods 324. There are eight guiding grooves 3221 corresponding to the expansion rods 324 on the expansion plate 322, and the eight guiding grooves 3221 are evenly spaced along the circumferential direction of the expansion plate 322. When it is necessary to expand the sealing ring 10, first place the sealing ring 10 at the second ends of the eight expansion rods 324. Then, the first driving assembly 200 drives the driving rack 210 to move along the A direction, so as to drive the corresponding transmission gear 310 to rotate along the B direction. At the same time, the transmission gear 310 drives the expansion plate 322 to rotate along the B direction through the connecting shaft 323. Since the limiting cylinder 321 is fixedly connected to the mounting frame 100, and the first ends of the eight expansion rods 324 are movably connected to the limiting cylinder 321, and the guiding grooves 3221 are arranged as arc-shaped grooves protruding radially from the expansion plate 322 in the direction away from the B direction. Therefore, when the expansion plate 322 rotates along the B direction, the expansion rods 324 move along the arc-shaped grooves in the radial direction of the expansion plate 322, so that the second ends of the expansion rods 324 move in the direction away from the center of the expansion plate 322. Thus, as the transmission gear 310 drives the expansion plate 322 to move, the eight expansion rods 324 cooperate with each other, so that the sealing ring 10 placed at the second ends of the eight expansion rods 324 is expanded, facilitating subsequent processing steps.

[0056] In some other embodiments, the number of the expansion rods 324 can be appropriately increased or decreased according to actual needs. For example, the number of the expansion rods 324 can be set to six, nine or ten, and the number and positions of the guiding grooves 3221 are correspondingly set with the expansion rods 324. Alternatively, multiple guiding grooves 3221 can be all arranged as arc-shaped grooves protruding in the direction close to the B direction. In this setting, when the first driving assembly 200 drives the driving rack 210 to move in the opposite direction of the A direction, multiple sets of ring expanding assemblies 320 can be driven to open simultaneously by the engagement of the driving rack 210 with multiple transmission gears 310, so as to expand multiple sealing rings 10 simultaneously.

[0057] Combined with Figures 4 to 6As shown, in some embodiments, since the first ends of the eight spreading rods 324 pass through the corresponding guide grooves 3221 and are movably connected to the limiting cylinder 321, rather than the first ends of the eight spreading rods 324 being directly slidably connected to the corresponding guide grooves 3221; therefore, the limiting cylinder 321 cooperates with the expansion disk 322 to further adaptively limit the first ends of the eight spreading rods 324, so as to improve the connection strength and connection stability between the eight spreading rods 324 and the expansion disk 322, thereby ensuring the operation stability of the support ring assembly 320. In addition, in order to further improve the transmission accuracy, connection strength and connection stability, the expansion disk 322 and the connecting shaft 323 are integrally formed. In other embodiments, according to actual needs, after the expansion disk 322 and the connecting shaft 323 are separately formed, the first end of the connecting shaft 323 is connected to the lower end surface of the expansion disk 322 by welding, bonding, connection with a threaded connector, etc., so as to improve the assembly convenience of the support ring assembly 320.

[0058] In order to further improve the convenience and stability of the expansion rod 324 when it moves along the corresponding arc groove in the radial direction of the expansion plate 322, Figure 5 As shown, in some embodiments, corresponding to the plurality of guide grooves 3221, the upper end surface of the limiting cylinder 321 is provided with a plurality of guide grooves 3211 at intervals along its circumference, each guide groove 3211 extends along the radial direction of the limiting cylinder 321, and the first ends of the plurality of opening rods 324 are slidably connected to the plurality of guide grooves 3211 one by one. When the opening rod 324 moves along the arc groove in the radial direction of the expansion plate 322, the movement of the entire opening rod 324 is ensured to be consistent, and the opening rod 324 is prevented from tilting, so as to further improve the operation stability of the support ring assembly 320.

[0059] Furthermore, a guide slide bar 3241 is provided at the first end of the expansion rod 324, and the axis of the guide slide bar 3241 is arranged perpendicular to the axis of the expansion rod 324. The guide slide bar 3241 is slidably connected to the corresponding guide groove 3211. The connection area between the first end of the expansion rod 324 and the guide groove 3211 is increased by the guide slide bar 3241, so as to further improve the connection strength and connection stability when the first end of the expansion rod 324 is connected to the corresponding guide groove 3211.

[0060] Furthermore, the width of the bottom end of the guide groove 3211 is greater than the width of the opening of the guide groove 3211, and the guide slide bar 3241 is aligned with the guide groove 3211, and the diameter of the guide slide bar 3241 is greater than the width of the opening of the guide groove 3211. This prevents the guide slide bar 3241 from being separated from the guide groove 3211 along the C direction when the guide slide bar 3241 slides in the corresponding guide groove 3211, so as to further improve the stability of the expansion rod 324 when it is connected to the limit cylinder 321. According to actual needs, along the length direction of the guide groove 3211, the cross-sectional area of the guide groove 3211 can be set to be trapezoidal, dovetail or "⊥" shape.

[0061] In addition, in some embodiments, at least one connecting portion 3212 is provided on the outer wall of the limiting cylinder 321, and the limiting cylinder 321 is fixedly connected to the mounting frame 100 through the connecting portion 3212; and the ends of the plurality of guide grooves 3211 that are away from the center of the limiting cylinder 321 are all set as closed ends, so that when the opening plate 322 rotates along the direction B so that the expansion rod 324 moves along the arc groove in the radial direction of the opening plate 322, it is possible to avoid the guide sliding rod 3241 from being separated from the limiting cylinder 321 in the radial direction of the limiting cylinder 321, so as to further improve the stability of the expansion rod 324 when it is connected to the limiting cylinder 321.

[0062] In some embodiments, the second end of each opening rod 324 is provided with a support step 3242, and each support step 3242 is provided on the side of the opening rod 324 away from the center of the opening plate 322, and multiple support steps 3242 cooperate to form a storage space for supporting the sealing ring 10. In this way, when the sealing ring 10 is placed on the second end of each opening rod 324, it can be ensured that the sealing ring 10 is always located in the storage space, thereby preventing the sealing ring 10 from being separated from each opening rod 324, so as to ensure the opening effect of the sealing ring 10.

[0063] In some other embodiments, the second end of each expansion rod 324 is provided with a receiving step, and each receiving step is provided on the side of the expansion rod 324 close to the center of the expansion plate 322, and the multiple receiving steps cooperate with each other to form a receiving space. When it is necessary to sleeve the sealing ring 10 on the sealing groove of the target suction nozzle, the sealing ring 10 can be first expanded, and then the target suction nozzle can be placed in the receiving space; then the first driving component 200 drives the driving rack 210 to move in the opposite direction of direction A, so that each expansion rod 324 moves in the direction close to the center of the limiting cylinder 321, so that the expanded sealing ring 10 is sleeved in the sealing groove of the target suction nozzle in the receiving space under the action of its own contraction, thereby completing the assembly of the sealing ring 10 and the target suction nozzle. In this embodiment, the structure and principle are explained by taking the first driving component 200 driving the driving rack 210 to move along the A direction so that the sealing ring 10 placed in the storage space is stretched, and the target suction nozzle and the sealing ring 10 are assembled as an example. In actual operation, the target assembly parts in the accommodating space are placed according to actual needs and are not limited to the target suction nozzle.

[0064] Combination Figure 6 As shown, in some embodiments, the support ring assembly 320 also includes a bearing plate 325 and an auxiliary bearing 326, and the bearing plate 325 and the auxiliary bearing 326 are both sleeved in the middle of the connecting shaft 323, the bearing plate 325 is fixedly connected to the lower end surface of the limiting cylinder 321, the outer ring of the auxiliary bearing 326 abuts against the inner wall of the limiting cylinder 321, and the inner ring is tightly matched with the connecting shaft 323.

[0065] Specific combination Figure 6 As shown, by setting the auxiliary bearing 326, the transmission effect between the transmission gear 310 and the connecting shaft 323 is ensured, and the connecting shaft 323 and the limiting cylinder 321 are always coaxial, so as to avoid the relative displacement between the connecting shaft 323 and the limiting cylinder 321 under the action of centrifugal separation during the rotation of the connecting shaft 323, so as to further improve the movement stability of the connecting shaft 323 and the expansion plate 322 and the operation stability of the support ring assembly 320. The bearing plate 325 is sleeved on the connecting shaft 323, and the bearing plate 325 is fixedly connected to the lower end of the auxiliary bearing 326, and is connected to the lower end surface of the limiting cylinder 321 through a threaded connector (not shown in the figure), so as to ensure the connection effect between the auxiliary bearing 326 and the limiting cylinder 321, so as to avoid the relative displacement between the auxiliary bearing 326 and the limiting cylinder 321 during the rotation of the connecting shaft 323. The auxiliary bearing 326 is set as a rolling bearing, and the specific structure refers to the prior art, which will not be repeated here.

[0066] Combination Figures 1 to 3As shown, in some embodiments, the mounting frame 100 can be configured as a box body, and the driving rack 210 and the multiple groups of support ring mechanisms 300 are all arranged in the mounting frame 100; the top plate of the mounting frame 100 is provided with installation channels corresponding to the multiple groups of support ring mechanisms 300, the outer peripheral wall of the expansion disk 322 abuts against the corresponding installation channel, the limiting cylinder 321 is fixedly connected to the top plate of the mounting frame 100 corresponding to the expansion disk 322, and the two side walls of the mounting frame 100 arranged along the A interval are provided with avoidance holes 110 for allowing the driving rack 210 to pass through.

[0067] Specifically, the drive rack 210 and the multiple support ring mechanisms 300 can be both arranged in the mounting frame 100, and the mounting frame 100 plays a protective role for the drive rack 210 and the multiple support ring mechanisms 300, preventing external debris or other structures from causing damage to the drive rack 210 or the multiple support ring mechanisms 300, ensuring the use effect of the expansion device and extending its service life. The limit cylinder 321 is fixedly connected to the top plate of the mounting frame 100 through the connecting portion 3212, and the upper end of the limit cylinder 321 is inserted into the corresponding installation channel, so that the ends of the multiple guide grooves 3211 away from the center of the limit cylinder 321 are all abutted against the inner wall of the installation channel to form a closed end, and the outer peripheral wall of the expansion plate 322 is abutted against the corresponding installation channel, so that the second ends of the multiple expansion rods 324 pass through the corresponding guide grooves 3221 and extend out of the mounting frame 100, so as to improve the convenience of expanding the sealing ring 10. Since the avoidance holes 110 are arranged on the two side walls of the mounting frame 100 arranged along the interval A, when the first driving component 200 drives the driving rack 210 to move along the A direction, the two ends of the driving rack 210 can pass through the corresponding avoidance holes 110 without leaving the avoidance space in the mounting frame 100, thereby improving the compactness of the internal components of the mounting frame 100 and reducing the spatial volume of the mounting frame 100.

[0068] Preferably, combined Figure 1 and Figure 7 As shown, the support ring device also includes a frame 400, a support plate 500 and a second drive assembly 600; the mounting frame 100 is movably arranged on the frame 400, the support plate 500 is fixedly arranged above the mounting frame 100, and the support plate 500 is provided with a receiving groove 501 corresponding to the multiple groups of support ring mechanisms 300 to allow the support ring assembly 320 to pass through, the second drive assembly 600 is arranged on the frame 400, and the second output shaft of the second drive assembly 600 is transmission-connected to the mounting frame 100 to drive the mounting frame 100 to rise and fall along the C direction.

[0069] Combination Figure 1 , Figure 2 and Figure 7As shown, in some embodiments, four circular receiving grooves 501 are correspondingly provided on the support plate 500. When the second driving assembly 600 drives the mounting frame 100 to rise along the C direction, the second ends of the plurality of expanding rods 324 in each set of support ring mechanisms 300 extend above the support plate 500 through the corresponding receiving grooves 501.

[0070] Combining the mounting frame 100 and the support ring mechanism 300, the working process of the entire support ring device is as follows: First, place the unsealed sealing ring 10 on the support plate 500 corresponding to the receiving groove 501. Then, the second driving assembly 600 drives the mounting frame 100 to rise along the C direction, so that the second ends of the plurality of expanding rods 324 in each set of support ring mechanisms 300 extend above the support plate 500 through the corresponding receiving grooves 501. As the mounting frame 100 rises, the second ends of the plurality of expanding rods 324 in each set of support ring mechanisms 300 all pass through the corresponding sealing ring 10, so that the sealing ring 10 is located in the corresponding storage space. Then, the first driving assembly 200 drives the driving rack 210 to move along the A direction, so that the plurality of expanding rods 324 in each set of support ring mechanisms 300 all move in a direction away from the center of the expansion disc 322, thereby expanding the sealing ring 10 in the storage space, so as to facilitate sleeving the expanded sealing ring 10 on the corresponding target part. Then, the first driving assembly 200 drives the driving rack 210 to move in a direction away from the A direction, so that the plurality of expanding rods 324 in each set of support ring mechanisms 300 are reset. Then, the second driving assembly 600 drives the mounting frame 100 to descend along the C direction, and places the unsealed sealing ring 10 on the support plate 500 corresponding to the receiving groove 501 again, and repeats the above steps.

[0071] Combined with Figure 1 and Figure 7 As shown, in some embodiments, a plurality of support teeth 5011 are provided on the inner wall of the receiving groove 501. The plurality of support teeth 5011 are evenly spaced along the circumferential direction of the receiving groove 501, and an avoidance groove 5012 is formed between adjacent two support teeth 5011. Before the support ring device works, place the unsealed sealing ring 10 on the plurality of support teeth 5011 in the corresponding receiving groove 501 to limit the relative position of the unsealed sealing ring 10 in this state and prevent the unsealed sealing ring 10 from slipping off the support plate 500. An avoidance groove 5012 is formed between adjacent two support teeth 5011, and eight avoidance grooves are provided along the circumferential direction of the receiving groove 501. When the second driving assembly 600 drives the mounting frame 100 to rise along the C direction, the eight expanding rods 324 extend above the support plate 500 from the eight avoidance grooves one by one. The eight avoidance grooves cooperate with each other to further improve the stability of the eight expanding rods 324 during the rising process, thereby further ensuring the expanding effect on the sealing ring 10.
