[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0030] The directional words appearing in the following description are all directions shown in the figure, and do not limit the specific structure of the bonding tooling of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0031] The sealing ring must be replaced during the entire life cycle of the wind turbine generator set. Since the bearing of the wind turbine generator set is connected to each clamping part 21, the sealing ring must be replaced by a split sealing ring and then bonded to close the sealing ring.

[0032] Among them, the cross-sectional structure of the sealing ring of the wind turbine generator set is mostly a special-shaped structure, so it is difficult to ensure the alignment of the interface of the sealing ring simply by manual labor during bonding. If the interface bonding is misaligned, a gap will appear at the interface of the sealing ring after the sealing ring is set on the bearing, resulting in a loose seal. In addition, it may also cause loose bonding. During use, the interface may gradually open due to friction, the sealing joint may separate, and a gap may appear, causing a large amount of grease leakage.

[0033] In addition, manual bonding requires tightening the two ends of the sealing ring, and the glue needs to be kept stable after it is applied to allow the glue to solidify. If there is shaking during the curing process of the glue or the two ends become loose due to insufficient tightening force, the bonding will be loose, and the old glue will need to be scraped off and re-bonded, and the bonding quality is difficult to guarantee.

[0034] In order to solve the above technical problems, the embodiments of the present application provide a bonding tool. The bonding tool provided in the embodiments of the present application can be used for bonding sealing rings, especially in the field of wind power technology, to bond sealing rings with special-shaped structures. The following embodiments of the present application only use the bonding of sealing rings with special-shaped structures as an example to illustrate the bonding tool, but the application of the bonding tool in the embodiments of the present application is not limited to the following embodiments, and can also be used for bonding ports of other split components and protecting them.

[0035] In order to better understand this application, Figures 1 to 7 The bonding tool according to the embodiment of the present application is described in detail.

[0036] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a bonding tool, which includes a support member 1 and a clamping member 2. The support member 1 is provided with a connecting portion 11. The clamping member 2 includes at least two clamping portions 21 arranged in cooperation along a first direction X. The clamping portion 21 is detachably connected to the connecting portion 11. The clamping portion 21 is provided with a connecting groove 211 that passes through along the first direction X. At least one clamping portion 21 in the clamping member 2 can move along the first direction X, and the connecting grooves 211 of each clamping portion 21 can be connected to each other.

[0037] The bonding tool in the embodiment of the present application includes a support member 1 and a clamping member 2 detachably connected to the support member 1, the clamping member 2 includes at least two clamping parts 21 arranged in cooperation along the first direction X, the clamping part 21 is provided with a connecting groove 211 passing through along the first direction X, when replacing the sealing ring, the end of the sealing ring can be at least partially embedded in the connecting groove 211, and the alignment and bonding of the sealing ring interface can be controlled by moving at least one clamping part 21 along the first direction X. In addition, since the clamping part 21 is detachably connected to the support member 1, when the bonding tool is actually used, the clamping part 21 on the support member 1 can be replaced according to the specifications of the sealing ring to be bonded, so that the bonding of sealing rings of various specifications can be achieved, while ensuring the bonding accuracy, the applicability of the bonding tool is improved.

[0038] Optionally, the clamping portion 21 can be connected to the connecting portion 11 in any detachable manner in the prior art. For example, the connecting portion 11 and the clamping portion 21 can be respectively provided with a first connecting hole 13 and a second connecting hole 213. The bonding tool can also include bolts. The clamping portion 21 can be detachably connected to the connecting portion 11 by sequentially passing the bolts through the first connecting hole 13 and the second connecting hole 213.

[0039] It is understandable that for the variable pitch and yaw bearings of wind turbines, the sealing rings mainly include single-lip structures, double-lip structures, four-lip structures or other cross-sectional structures that need to be customized. Therefore, for wind turbines, multiple clamps 2 can be provided, each clamp 2 corresponds to a sealing ring with a cross-sectional structure, that is, the cross-sectional shapes of the connecting grooves 211 in the multiple clamps 2 are different, and the cross-sectional shapes of the connecting grooves 211 in each clamp 2 are matched with a sealing ring with a cross-sectional structure, so that in actual use, the clamp 2 on the support 1 can be replaced according to the cross-sectional structure of the sealing ring to be bonded, so as to achieve the bonding of sealing rings of corresponding specifications.

[0040] Among them, since each clamping member 2 includes at least two clamping parts 21, the cross-sectional shapes of the connecting grooves 211 in the multiple clamping members 2 are different. Specifically, the cross-sectional shapes of the connecting grooves 211 of each clamping part 21 on the same clamping member 2 are the same, and the cross-sectional shapes of the connecting grooves 211 of the clamping parts 21 of the multiple clamping members 2 are different. Therefore, when the clamping member 2 needs to be replaced in actual use, it is necessary to replace each clamping part 21 connected to the current support member 1 with the clamping part 21 of another clamping member 2 to achieve the bonding of the sealing ring of the corresponding specification.

[0041] It should be noted that the clamping member 2 includes at least two clamping parts 21 arranged in cooperation along the first direction X, which means that the number of the clamping parts 21 can also be two, and the two clamping parts 21 are respectively used to clamp the two ends of the sealing ring to achieve the docking of the sealing ring. Alternatively, the number of the clamping parts 21 can also be more than two. For example, when the sealing ring is lengthened, three clamping parts 21 can also be provided, wherein the clamping parts 21 located on both sides are respectively used to clamp the two ends of the sealing ring, and the clamping part 21 located in the middle is used to clamp the lengthened section, and the sealing ring is closed by bonding the lengthened section to the two ends of the sealing ring.

[0042] For ease of understanding, the following description is made by taking the example that the clamping member 2 includes two clamping portions 21 arranged in pairs along the first direction X, wherein the clamping portions 21 arranged in pairs are respectively defined as a first clamping portion 21 a and a second clamping portion 21 b .

[0043] See also Figure 1 and Figure 2 In some embodiments, the support member 1 can be set as an integrated structure. In this case, in order to facilitate the movement of at least one clamping portion 21 along the first direction X, in some optional embodiments, the connecting portion 11 is extended along the first direction X, and in the clamping member 2, at least one clamping portion 21 is slidably connected to the connecting portion 11 along the first direction X.

[0044] Taking the example of the first clamping portion 21a being slidably connected to the connecting portion 11 along the first direction X, the connecting portion 11 can be extended along the first direction X and play a guiding role. The guiding limit of the first clamping portion 21a can be achieved through the connecting portion 11, so that the first clamping portion 21a can be connected to the second clamping portion 21b along the first direction X, thereby improving the stability of the bonding process, ensuring the sealing performance of the sealing ring after bonding, and reducing the risk of grease leakage caused by the sealing ring debonding or opening.

[0045] Optionally, the connecting portion 11 may be configured as a guide rail, and the clamping portion 21 may be provided with a groove, and the clamping portion 21 is connected to the guide rail so that the clamping portion 21 moves relative to the guide rail along the first direction X. Optionally, the connecting portion 11 may also be configured as a guide groove, and the clamping portion 21 is at least partially embedded in the guide groove so that the clamping portion 21 is slidably arranged along the guide groove along the first direction X.

[0046] When the connecting portion 11 is configured as a guide groove, in some optional embodiments, the guide groove forms a first opening at at least one end of the support member 1 along the first direction X, and a first limiting portion 111 is provided on the support member 1. At least one clamping portion 21 is slidably connected to the guide groove through the first opening, and the first limiting portion 111 can limit the freedom of movement of the clamping portion 21 in the direction of the notch of the guide groove.

[0047] Among them, the clamping part 21 can be embedded in the guide groove through the first opening. Since the first limiting part 111 is arranged in the guide groove, after the clamping part 21 is at least partially embedded in the guide groove, the clamping part 21 can be fixed to the guide groove in a plane perpendicular to the first direction X, thereby further improving the stability of the clamping part 21 moving along the first direction X, improving the alignment accuracy of the connecting groove 211 on the first clamping part 21a and the second clamping part 21b, and ensuring the sealing performance of the sealing ring after bonding.

[0048] Optionally, the first limiting portion 111 can be provided integrally with the guide groove to simplify the manufacturing difficulty. The first limiting portion 111 can be provided at the notch of the guide groove, and the degree of freedom of movement of the clamping portion 21 in the direction of the notch of the guide groove can be limited by reducing the notch area of ​​the guide groove. Alternatively, the first limiting portion 111 can also be provided in the guide groove, and the clamping portion 21 can be provided with a flange 212 protruding toward the guide groove, and the degree of freedom of movement of the clamping portion 21 in the direction of the notch of the guide groove can be limited by blocking the first limiting portion 111 on the side of the flange 212 facing the notch of the guide groove.

[0049] Among them, the direction of the groove opening of the disengagement guide groove refers to, taking the guide groove being arranged on a side surface of the connecting portion 11 along the second direction Y as an example, the direction of the groove opening of the disengagement guide groove is the second direction Y, that is, the first limiting portion 111 is used to limit the freedom of movement of the clamping portion 21 along the second direction Y.

[0050] It can be understood that, for the above-mentioned bonding tooling, at least one clamping portion 21 is slidably connected to the guide groove through the first opening. The first clamping portion 21a can be slidably connected to the guide groove along the first direction X, and the second clamping portion 21b can be fixed to the guide groove along the first direction X. Alternatively, both the first clamping portion 21a and the second clamping portion 21b can be slidably connected to the guide groove along the first direction X, which can ensure that the first clamping portion 21a and the second clamping portion 21b are connected to each other along the first direction X.

[0051] See also Figure 3 In some optional embodiments, the guide groove is through-through along the first direction X and forms first openings at both ends of the support member 1 along the first direction X, and the clamping parts 21 are respectively inserted into the corresponding first openings and slidably connected to the guide groove. That is, in the case where both the first clamping part 21a and the second clamping part 21b can be slidably connected to the guide groove, the guide groove can be through-through along the first direction X, and the first clamping part 21a and the second clamping part 21b can be respectively inserted from the first openings at both ends and move toward each other along the first direction X to achieve the docking of the first clamping part 21a and the second clamping part 21b along the first direction X.

[0052] Among them, since the guide groove runs through along the first direction X, it is easier to manufacture and form, reducing the difficulty of manufacturing and designing the bonding tooling, and the precision of the formed guide groove is higher, which can further improve the docking accuracy of the first clamping part 21a and the second clamping part 21b along the first direction X, and improve the sealing performance of the sealing ring after bonding.

[0053] See also Figures 1 to 3 When using the bonding tool in the above embodiment, the clamping member 2 that matches the sealing ring to be bonded can be selected according to the cross-sectional structure of the sealing ring to be bonded. For example, the first clamping portion 21a and the second clamping portion 21b are both slidably connected to the guide groove along the first direction X, and one end of the sealing ring can be clamped by the first clamping portion 21a, and the other end of the sealing ring can be clamped by the second clamping portion 21b. Then, the first clamping portion 21a and the second clamping portion 21b are respectively embedded in the guide groove through the first opening and move toward each other along the first direction X, and the moving line of the end of the sealing ring is fixed to achieve the alignment bonding of the sealing ring interface.

[0054] See also Figures 4 to 7 In other embodiments, the support member 1 may also be configured as a split structure, in which case it is convenient for at least one clamping portion 21 to move along the first direction X. In some optional embodiments, the support member 1 includes at least two support portions 12 arranged in cooperation along the first direction X, each support portion 12 is provided with a connecting portion 11, each clamping portion 21 is detachably connected to the connecting portion 11 of one of the support portions 12, and two adjacent support portions 12 are slidably connected along the first direction X.

[0055] That is, when the support member 1 is configured as a split structure, in addition to utilizing the above-mentioned embodiment to make the first clamping portion 21a slidably connected to the connecting portion 11 along the first direction X, after the clamping portion 21 is connected to the connecting portion 11 of the support portion 12, the support portions 12 can slide relative to each other along the first direction X to drive the clamping portion 21 thereon to move along the first direction X, thereby achieving the mutual docking of the connecting grooves 211 of each clamping portion 21.

[0056] The support member 1 includes at least two support portions 12 arranged in cooperation along the first direction X, the number of the support portions 12 is greater than or equal to the number of the clamping portions 21, and each clamping portion 21 is detachably connected to the connecting portion 11 of one of the support portions 12. Optionally, the number of the support portions 12 is the same as the number of the clamping portions 21, so as to simplify the structure of the bonding tool and facilitate the bonding operation.

[0057] Taking the example of the clamping member 2 including the first clamping portion 21a and the second clamping portion 21b, the support portion 12 is correspondingly defined as the first support portion 12a connected to the first clamping portion 21a, and the second support portion 12b connected to the second clamping portion 21b. The first support portion 12a and the second support portion 12b are slidably arranged along the first direction X to achieve the alignment and bonding of the interfaces at both ends of the sealing ring.

[0058] Optionally, the support member 1 may further include a guide rod extending along the first direction X. The guide limitation of the support portion 12 along the first direction X can be achieved by correspondingly arranging guide holes on each support portion 12 and by penetrating the guide holes of each support portion 12 on the guide rod. Alternatively, the support member 1 may also achieve a sliding connection through the cooperation of a concave and convex structure.

[0059] Specifically, on the end surfaces of two adjacent support parts 12 facing each other, one is provided with a convex part 121, and the other is provided with a concave part 122 matching with the convex part 121, and the convex part 121 is inserted into the concave part 122 along the first direction X and is slidably connected with the concave part 122. For example, the convex part 121 can be provided on the first support part 12a, and the concave part 122 can be provided on the second support part 12b, so that a concave-convex structure can be formed to achieve the guide limit between the first support part 12a and the second support part 12b, and the above structure is simpler, more reliable, and more stable.

[0060] Optionally, the cross-section of the protrusion 121 along the first direction X may be non-circular, for example, rectangular, so as to avoid relative rotation when two adjacent support portions 12 move toward each other along the first direction X, reduce the possibility of relative twisting of the interface when the sealing ring is bonded, and further improve the bonding effect of the sealing ring interface.

[0061] In addition, the protrusion 121 can be set as an integrated structure with the first support portion 12a, or the support member 1 also includes a connecting rod, which is connected to the first support portion 12a and protrudes relative to the end of the first support portion 12a to form the protrusion 121, that is, the specific molding method of the protrusion 121 can be adjusted according to the specific structure of the support portion 12, and can satisfy the matching connection between the protrusion 121 and the recessed portion 122.

[0062] It is understandable that when using the bonding tool in the above embodiment, the clamping member 2 that matches the sealing ring to be bonded can be selected according to the cross-sectional structure of the sealing ring to be bonded. Taking the support member 1 as an example, which includes a first support portion 12a and a second support portion 12b that are separately arranged, the first clamping portion 21a can be first connected to the connecting portion 11 of the first support portion 12a to form a first-part installation structure, and one end of the sealing ring can be clamped by the first-part installation structure, and then the second clamping portion 21b can be connected to the connecting portion 11 of the second support portion 12b to form a second-part installation structure, and the other end of the sealing ring can be clamped by the second-part installation structure. Furthermore, through the guiding cooperation of the convex portion 121 and the concave portion 122, the first-part installation structure and the second-part installation structure are moved toward each other along the first direction X, and the moving line of the end of the sealing ring is fixed to achieve the alignment bonding of the sealing ring interface.

[0063] See also Figures 1 to 7 For the sealing ring, before installing it in the bonding tool in the embodiment of the present application, adhesive glue can be applied to the end of the sealing ring, or before installing it in the bonding tool in the embodiment of the present application, adhesive glue can be injected using the bonding tool.

[0064] Specifically, in some optional embodiments, at least one clamping portion 21 is provided with a guide channel, which extends to the butt joint surface between the clamping portions 21 and is connected to the connecting groove 211. By providing the guide channel on the clamping portion 21, after the sealing ring interface is aligned by using the bonding tool, glue can be injected into the guide channel to guide the glue to the butt joint surface between the sealing rings, thereby achieving bonding between the sealing rings.

[0065] Further, along the first direction X, the connecting surface of the clamping portion 21 is correspondingly provided with a guide groove 215, the guide groove 215 is connected with the connecting groove 211, and the guide grooves 215 of the clamping portion 21 are connected to each other and combined to form a guide channel. By directly providing the guide groove 215 on the connecting surface of the clamping portion 21, the structure is simpler and more reliable than providing the guide channel on one of the clamping portions 21.

[0066] Optionally, when the support member 1 is divided into a support portion 12, a liquid injection groove 14 may be correspondingly provided on the docking surface of the support portion 12, and the liquid injection groove 14 is connected to the guide groove 215, and the liquid injection groove 14 and the guide groove 215 may be arranged along a third direction Z, and the third direction Z intersects with the first direction X and the second direction Y, and the third direction Z is a vertical direction, so that it is easier for the glue to be drained to the docking surface between the sealing rings under the action of its own gravity, thereby improving the reliability of the alignment bonding.

[0067] See also Figures 1 to 7 For the bonding tool in the above embodiment, after the sealing ring interface is aligned and bonded, it is necessary to remove the bonding tool to take out the sealing ring. Therefore, in order to facilitate the removal of the sealing ring, in some optional clamping members 2, the connecting groove 211 of each clamping portion 21 forms a second opening on the same side of the second direction Y, and the second direction Y intersects with the first direction X. A second limiting portion 214 is also provided on the clamping portion 21, and the second limiting portion 214 is used to limit the member to be clamped in the connecting groove 211.

[0068] The part to be clamped is a sealing ring. Since the sealing ring is usually made of nitrile rubber, it has a certain amount of elastic deformation. Therefore, by forming a second opening along the second direction Y in the connecting groove 211 of the clamping portion 21, the sealing ring can be directly taken out from the second opening by utilizing its deformation after being aligned and bonded. Alternatively, in order to reduce the impact on the bonding area of ​​the sealing ring, the sealing ring can also be moved relative to the bonding tool along the first direction X, thereby avoiding the bonding area of ​​the sealing ring to take out the sealing ring from the second opening, which is more convenient to operate.

[0069] On this basis, by setting a second limiting portion 214 on the clamping portion 21 to limit the sealing ring in the connecting groove 211, the possibility of the sealing ring detaching from the second opening before being bonded and fixed can be reduced, the bonding process stability is further improved, and the sealing performance of the sealing ring is ensured.

[0070] Optionally, the second limiting portion 214 may be integrally provided at the second opening of the communicating groove 211 , and limit the freedom of movement of the sealing ring in a direction away from the communicating groove 211 by blocking the second opening of the communicating groove 211 .

[0071] Optionally, the second limiting portion 214 can also be set as a bolt. For example, when the first connecting hole 13 and the second connecting hole 213 are correspondingly opened on the support member 1 and the clamping portion 21, the second connecting hole 213 can be connected to the connecting groove 211. The second limiting portion 214 passes through the first connecting hole 13 and the second connecting hole 213 in sequence and can abut against the sealing ring set in the connecting groove 211.

[0072] That is, the second limiting portion 214 can be reused as a bolt for the first connecting hole 13 and the second connecting hole 213. By connecting the second connecting hole 213 and the connecting groove 211, the second limiting portion 214 can be used to press on the sealing ring before the sealing ring is bonded and fixed, so as to fix the sealing ring and prevent the sealing ring from sliding or loosening during alignment bonding, thereby further improving the reliability of the alignment bonding of the sealing ring.

[0073] To facilitate understanding of the present application, the support member 1 is divided into a first support portion 12a and a second support portion 12b, that is, Figures 4 to 7 Taking the embodiment of the present invention as an example, the steps for using the bonding tool in the embodiment of the present application are described, specifically including:

[0074] When using the bonding tool in the above embodiment, a clamping member 2 matching the cross-sectional structure of the sealing ring to be bonded can be selected first.

[0075] The first connecting hole 13 and the second connecting hole 213 are sequentially penetrated by bolts, and the first clamping portion 21a is connected to the connecting portion 11 of the first supporting portion 12a to form a first part of the mounting structure, and then one end of the sealing ring is clamped by the first part of the mounting structure.

[0076] The first connecting hole 13 and the second connecting hole 213 are sequentially penetrated by bolts, and the second clamping portion 21b is connected to the connecting portion 11 of the second supporting portion 12b to form the second part of the mounting structure, and then the other end of the sealing ring is clamped by the first part of the mounting structure.

[0077] Through the guiding cooperation of the convex portion 121 and the concave portion 122 , the mounting structure of the first part and the mounting structure of the second part are moved toward each other along the first direction X to achieve docking of the interfaces at both ends of the sealing ring.

[0078] The bolts of the first and second parts of the mounting structure are used to abut against the sealing ring to limit the sealing ring, and then the adhesive glue is injected into the guide channel. After the glue flows into the joint surface between the sealing rings, the entire structure is kept stable for more than 10 minutes.

[0079] After the glue is cured, loosen the bolts and take the sealing ring out from the second opening to achieve alignment and bonding of the sealing ring.

[0080] It can be understood that the above-mentioned bonding tool can be used to achieve the alignment bonding method of the ends of sealing rings of various specifications, which can improve the alignment accuracy compared to the manual bonding method. The bonding tool also has the advantages of being easy to carry, easy to operate, saving manpower and time, and is more suitable for various use environments, such as bonding work when replacing sealing rings on site.

[0081] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
