[0065] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0066] like Figures 1 to 4 As shown, according to an embodiment of the present disclosure, a thin-walled part welding device is proposed, including: a tire mold assembly 100, having a mounting surface and a connecting surface, the mounting surface and the connecting surface are located at two ends of the tire mold assembly 100 in the axial direction, the mounting surface is used to mount the thin-walled part, the mounting surface is formed with a protruding structure 101, and the protruding structure 101 is used to abut against the thin-walled part; a support assembly 200, connected to the connecting surface; a clamping assembly 300, arranged on the tire mold assembly 100, and the clamping assembly 300 is used to fix the thin-walled part to the tire mold assembly 100; wherein, the shape of the protruding structure 101 is adapted to the shape of the thin-walled part, and when the thin-walled part is mounted on the mounting surface, the thin-walled part fits against the circumferential side of the protruding structure 101.

[0067] The thin-walled component welding device proposed in the embodiment of the present disclosure includes a tire mold component 100, a support component 200 and a clamping component 300, wherein the tire mold component 100 is respectively formed with a mounting surface and a connecting surface at both ends in the axial direction, the connecting surface is used to connect with the support component 200, so that the tire mold component 100 can be stably supported by the support component 200, and the mounting surface is used to install the thin-walled component to be processed and formed, and the mounting surface is formed with a protruding structure 101 whose shape is compatible with the thin-walled component; in actual application, the various components of the thin-walled component can be installed on the protruding structure 101 of the mounting surface, so that the various components of the thin-walled component are fitted to the protruding structure 101, and then the clamping component 300 is clamped. Component 300 is installed on the tire mold component 100 so that the various components of the thin-walled part are fixed on the tire mold component 100. The various components of the fixed thin-walled part are then connected in sequence to form a complete thin-walled part surrounding the circumference of the protruding structure 101. The connections between the various components of the thin-walled part can be connected by welding; since the various components of the thin-walled part are all attached to the protruding structure 101 and are fixed by the clamping component 300, therefore, during the welding process, the restrictions of the tire mold component 100 and the clamping component 300 can constrain the shapes of the various components of the thin-walled part, and can also inhibit the deformation of the various components of the thin-walled part, which is beneficial to improve the processing accuracy of the thin-walled part.

[0068] It can be understood that the flange 910, the skin 920, the U-shaped part 930 and the box-shaped part 940 in the thin-walled part can be manufactured by sheet metal forming processing methods such as gate pressing or rolling, and then the parts are abutted against the protruding structure 101 one by one through the shape adaptation relationship between the protruding structure 101 and the parts of the thin-walled part, so that the parts of the thin-walled part are installed on the mounting surface, and then fixed by the clamping assembly 300, so that the parts of the thin-walled part can be fully fitted to the protruding structure 101. At the same time, this process is also the shape adaptation of the parts of the thin-walled part. Correction can ensure that the shape and size of each component of the thin-walled part meet the requirements, and then the joints of each component are welded one by one by welding. Since the protruding structure 101 and the clamping assembly 300 fully restrict the thin-walled part, the position relationship and shape structure between the components of the thin-walled part can be relatively fixed, so as to ensure that the components of the thin-walled part can complete the whole process welding under accurate position and reliable constraint, and at the same time, the deformation of the thin-walled part can be avoided. The accuracy requirements of the shape and position of each component can be guaranteed without secondary machining, and the convenience of welding work can be improved.

[0069] It can be understood that since the various components of the thin-walled parts are manufactured by sheet metal forming, and since the components after sheet metal forming may have a certain amount of springback, they can be trial-assembled at the corresponding positions of the installation surface before welding to check whether the shape and size of the components meet the requirements to ensure that the components can fit the raised structure 101; at the same time, before installing each component on the installation surface, the surface of each component should be cleaned to remove oil, rust, attachments and oxide layers on the surface of the parts to ensure the welding quality during welding.

[0070] It can be understood that the thin-walled part is fitted on the circumferential side of the protruding structure 101, the thin-walled part is in a circular ring shape, and the outer ring of the tire mold assembly 100 is also circular. When the thin-walled part is installed on the mounting surface, the axis of the tire mold assembly 100 coincides with the axis of the thin-walled part. Such an arrangement also ensures that the coaxiality of the thin-walled part meets the requirements after processing.

[0071] It should be noted that in the prior art, thin-walled parts are often processed and formed by casting or sheet metal processing. However, due to the complex structure of the thin-walled parts, they cannot be directly formed in one step. The thin-walled parts can only be split into multiple parts and machined after sheet metal welding. In this process, except for the dimensions of the mounting holes and the outer circle which are guaranteed by machining, other dimensions need to be guaranteed by sheet metal clamp welding. However, the thin-walled parts have a complex structure, and after the parts are split, there are many assemblies and welds, and the welds are densely distributed. Accurate positioning of the components cannot be achieved. When processed by sheet metal clamp welding, the flatness, coaxiality and other dimensional accuracy of each component are difficult to guarantee, and the workload of shaping each component is large, and welding deformation is difficult to control. This leads to extremely low production efficiency of qualified thin-walled parts and inability to achieve mass production. Compared with the prior art, the thin-walled parts welding device proposed in the embodiment of the present invention, based on the above-mentioned settings, can realize the shape correction, positioning and splicing of various components of thin-walled parts, can reduce the deformation of thin-walled parts during the welding process, improve the processing accuracy and processing efficiency of the product, can save processing costs, shorten the processing cycle, save labor costs, and realize mass production of the thin-walled parts.

[0072] It should also be noted that due to the complex structure of the thin-walled part, during the product inspection process, some dimensions cannot be manually inspected by inspectors and can only be inspected by high-precision inspection equipment. The tire mold assembly 100 in the thin-walled part welding device proposed in the embodiment of the present disclosure can also be used as an inspection tire mold. By inspecting the degree of fit between the thin-walled part and the mounting surface of the tire mold assembly 100, it can be inspected whether the size and shape of the thin-walled part meet the requirements, which can not only reduce the investment in equipment resources, but also improve the inspection efficiency, further shorten the processing cycle, and save labor costs.

[0073] For example, various components of the thin-walled part may be welded into an integral thin-walled part by manual argon arc welding.

[0074] For example, the tire mold assembly 100 can be made of ordinary carbon steel, which has good manufacturing processability, convenient maintenance and low cost.

[0075] In some examples, such as Figure 1 and Figure 3 As shown, the protrusion structure 101 includes: a first protrusion 1011 for abutting against the U-shaped member 930 in the thin-walled member; a second protrusion 1012, and the second protrusion 1012 is provided with a groove, and the groove is used to abut against the box-shaped member 940 in the thin-walled member.

[0076] In the above technical solution, the protrusion structure 101 includes a first protrusion 1011 and a second protrusion 1012, wherein the first protrusion 1011 is used to abut against the U-shaped part 930 in the thin-walled part, and can position the U-shaped part 930 of the thin-walled part, and the second protrusion 1012 is used to position the box-shaped part 940 of the thin-walled part. The second protrusion 1012 is provided with a groove, and the shape of the groove is adapted to the shape of the box-shaped part 940, so that the box-shaped part 940 can abut against the groove wall of the groove to achieve positioning.

[0077] It can be understood that the U-shaped part 930 and the box-shaped part 940 of the thin-walled part can be installed on the installation surface first through the first protrusion 1011 and the second protrusion 1012, and the remaining skin 920 and flange edge 910 can be arranged based on the positional relationship between the U-shaped part 930 and the box-shaped part 940, thereby realizing the positioning of all components of the thin-walled part.

[0078] It is understandable that when the various components of the thin-walled parts are processed and formed, a certain overlap margin can be reserved so that the components arranged along the axial direction of the thin-walled parts overlap each other. On the one hand, it is easier to weld and is beneficial to improving welding accuracy. On the other hand, it is also beneficial to improve the accuracy of positioning between the components.

[0079] It can be understood that the thin-walled part includes four U-shaped parts 930, and the number of first protrusions 1011 is adapted to the number of U-shaped parts 930 of the thin-walled part, which is also four. Since there are shape differences between some U-shaped parts 930, certain shape differences can also be set between different first protrusions 1011 so that the first protrusions 1011 can adapt to the actual situation of the corresponding U-shaped parts 930.

[0080] It is understandable that in the traditional thin-walled parts welding technology, during the welding process, the parts will undergo certain deformation. In order to avoid affecting the accuracy of the hole position of the parts, mechanical processing and opening of holes are often performed after welding. At the same time, in order to overcome the impact of the deformation of the parts during the welding process, before the welding process, the parts to be welded are often reserved with a certain margin, and the excess margin is removed by subtractive manufacturing to eliminate the impact of the deformation of the parts after welding. However, it is technically difficult to perform mechanical processing on the finished thin-walled parts after welding, which is inconvenient for workers to operate. The thin-walled parts welding device proposed in the embodiment of the present disclosure can avoid deformation of the various parts of the thin-walled parts during the welding process. Therefore, before the various parts of the thin-walled parts are welded, mechanical processing such as opening the installation holes and positioning holes of the various parts can be completed first, thereby reducing the difficulty of mechanical processing. At the same time, there is no need to reserve processing margin, and qualified thin-walled parts can be directly obtained by welding, thereby realizing the zero-residue welding of the thin-walled parts, reducing material costs, and improving processing efficiency.

[0081] In some examples, such as Figure 1 and Figure 3 As shown, the tire mold assembly 100 includes: a connecting portion 110, a connecting surface is formed on the connecting portion 110; a tire mold portion 120, which is detachably arranged on the side of the connecting portion 110 away from the connecting surface, and a protruding structure 101 is formed on the tire mold portion 120; wherein the tire mold portion 120 is composed of a first tire mold 121 and a second tire mold 122, the first tire mold 121 and the second tire mold 122 are both detachably connected to the connecting portion 110, there is a gap between the first tire mold 121 and the second tire mold 122, and the gap between the first tire mold 121 and the second tire mold 122 is adjustable.

[0082] In the above technical solution, the tire mold assembly 100 includes a connecting portion 110 and a tire mold portion 120, wherein the connecting portion 110 is formed with a connecting surface, the connecting portion 110 is used to connect the support assembly 200, the tire mold portion 120 is arranged on the connecting portion 110, the tire mold portion 120 is formed with a protruding structure 101, and the tire mold portion 120 is composed of a first tire mold 121 and a second tire mold 122, the first tire mold 121 and the second tire mold 122 are both arranged on the connecting portion 110, and the first tire mold 121 and the second tire mold 122 are both detachably connected to the connecting portion 110, when the first tire mold 121 and the second tire mold 122 are connected to the connecting portion 110, the positional relationship between the first tire mold 121 and the second tire mold 122 is fixed to each other, and there is a gap, when the second tire mold 122 or the first tire mold 121 is detached from the connecting portion 110, the first tire mold The gap between 121 and the second mold 122 is adjustable. In actual application, the first mold 121 and the second mold 122 are both connected to the connecting portion 110, and the thin-walled part is arranged on the mounting surface, located on the peripheral side of the raised structure 101, that is, the thin-walled part surrounds the first mold 121 and the second mold 122 at the same time. In this case, the thin-walled part is attached to the raised structure 101. Since welding may cause a certain shrinkage of the thin-walled part, it is difficult for the thin-walled part to be demolded from the mold portion 120. At this time, the connection between the first mold 121 and the connecting portion 110 and / or the connection between the second mold 122 and the connecting portion 110 can be disconnected, and the gap between the first mold 121 and the second mold 122 can be adjusted to be reduced, thereby reducing the restriction of the mold portion 120 on the thin-walled part, so that at least part of the thin-walled part is separated from the mold portion 120, which is more conducive to the demolding of the thin-walled part.

[0083] It can be understood that the mounting surface is formed on the tire mold part 120, and the tire mold part 120 is adapted to the thin-walled part in a circular shape. There are protruding structures 101 on the first tire mold 121 and the second tire mold 122. The positional relationship of the protruding structure 101 on the first tire mold 121 and the second tire mold 122 is not further limited here.

[0084] Exemplarily, the first mold 121 and the second mold 122 each occupy half of the mold portion 120, and the connection between the first mold 121 and the second mold 122 is located at the circular diameter of the mold portion 120, which is more conducive to position adjustment of the first mold 121 and the second mold 122 relative to the thin-walled part.

[0085] For example, the first mold 121 and the connecting portion 110 may be connected by pins or screws, and the second mold 122 and the connecting portion 110 may be connected by pins or screws.

[0086] In some examples, such as Figure 1 and Figure 4As shown, the support assembly 200 includes: a rotating shaft portion 210, having a rotating shaft 211, one end of the rotating shaft 211 is connected to the connecting surface, and the rotating shaft 211 is arranged along the axial direction of the tire mold assembly 100; a supporting portion 220, and the rotating shaft portion 210 is arranged on the supporting portion 220; a locking portion 230, which is arranged on the rotating shaft portion 210 and is used to limit the rotation of the rotating shaft 211; wherein the locking portion 230 has a locking state and an unlocking state, when the locking portion 230 is in the locking state, the locking portion 230 limits the rotation of the rotating shaft 211, and when the locking portion 230 is in the unlocking state, the rotating shaft 211 can rotate relative to the supporting portion 220.

[0087] In the above technical solution, the support assembly 200 includes a rotating shaft portion 210, a supporting portion 220 and a locking portion 230, wherein the rotating shaft portion 210 is arranged on the supporting portion 220, and the locking portion 230 is arranged on the rotating shaft portion 210. The rotating shaft 211 of the rotating shaft portion 210 is arranged along the axial direction of the tire mold assembly 100, and a section of the rotating shaft 211 is connected to the connecting surface, so that the tire mold assembly 100 can be rotated by the rotation of the rotating shaft 211. The locking portion 230 is arranged on the rotating shaft portion 210 and can be used to limit the rotation of the rotating shaft 211. The locking portion 230 has two working states, a locked state and an unlocked state. When the locking portion 230 is in the locked state, the locking portion 230 can limit the rotation of the rotating shaft 211. The tire mold assembly 100 can be moved, that is, the tire mold assembly 100 can be fixed at a certain angle; when the locking portion 230 is in the unlocked state, the rotating shaft 211 can rotate relative to the supporting portion 220. At this time, the tire mold assembly 100 can rotate along with the rotating shaft 211 to adjust the angle. In actual applications, since the thin-walled part and the tire mold assembly 100 are both circular, the locking portion 230 is adjusted to the unlocked state, and the thin-walled part can be rotated to a position angle convenient for operation by rotating the rotating shaft 211. When the locking portion 230 is adjusted to the locked state, the tire mold assembly 100 is fixed, that is, the position of the thin-walled part is fixed, and then the welding operation is performed, which can improve the convenience of welding, and is also beneficial to improving the welding quality and processing efficiency.

[0088] In some examples, such as Figure 4 and Figure 5 As shown, the rotating shaft portion 210 further includes: a box body 212 , the rotating shaft 211 is disposed through the box body 212 ; a bearing 233 is disposed in the box body 212 and located between the box body 212 and the rotating shaft 211 ; wherein there is a gap between the connecting surface and the box body 212 .

[0089] In the above technical solution, the rotating shaft portion 210 also includes a box body 212 and a bearing 233. The rotating shaft 211 passes through the box body 212. The box body 212 is arranged on the support portion 220. The bearing 233 is arranged between the box body 212 and the rotating shaft 211, which can improve the smoothness of the rotation of the rotating shaft 211. At the same time, there is a gap between the connecting surface and the box body 212, which can ensure that there is a certain space between the box body 212 and the connecting surface, making it easier for operators to perform welding operations on the thin-walled parts located on the tire mold assembly 100.

[0090] In some examples, such as Figures 4 to 6 As shown, the locking portion 230 includes: a first clamping member 231, along the axial direction perpendicular to the rotating shaft 211, the box body 212 is provided with a slide, the first clamping member 231 is slidably arranged on the slide, the first clamping member 231 is provided with a first arc-shaped groove, the groove wall of the first arc-shaped groove is used to abut the rotating shaft 211; a second clamping member 232, fixedly arranged on the slide, the second clamping member 232 is provided with a second arc-shaped groove, the groove wall of the second arc-shaped groove is used to abut the rotating shaft 211; an adjusting member 233, along the extension direction of the slide, the adjusting member 233 is used to adjust the first arc-shaped groove to be close to or away from the first arc-shaped groove; wherein, along the extension direction of the slide, at least part of the rotating shaft 211 is located between the first arc-shaped groove and the second arc-shaped groove.

[0091] In the above technical solution, the locking portion 230 includes a first clamping member 231, a second clamping member 232 and an adjusting member 233. The box body 212 is provided with a slideway along the axial direction perpendicular to the rotating shaft 211. The first clamping member 231 and the second clamping member 232 are both arranged on the slideway, wherein the first clamping member 231 can slide relative to the slide, the second clamping member 232 is fixedly arranged on the slideway, and the adjusting member 233 adjusts the first clamping member 231 to slide along the slideway; a first arc groove is formed at one end of the first clamping member 231 close to the second clamping member 232, and a second arc groove is formed at one end of the second clamping member 232 close to the first clamping member 231. The first arc groove and the second arc groove are both used to abut the rotating shaft 211, along In the extension direction of the slide, at least a portion of the rotating shaft 211 is located between the first arc groove and the second arc groove. In actual application, when the locking portion 230 is in the unlocked state, the gap between the first clamping member 231 and the second clamping member 232 is relatively large, and the first clamping member 231 does not abut against the second clamping member 232. When the locking portion 230 is converted into the locked state, the first clamping member 231 can be adjusted to be close to the second clamping member 232 through the adjusting member 233, so that the first arc groove is close to the second arc groove. Since the rotating shaft 211 is located between the first arc groove and the second arc groove, as the first arc groove is close to the second arc groove, the first arc groove and the second arc groove can clamp the rotating shaft 211, thereby achieving braking of the rotating shaft 211.

[0092] It is understandable that when the locking portion 230 is in the locked state, the first clamping member 231 can be adjusted by the adjusting member 233 to move the first arc groove away from the second arc groove, thereby releasing the clamping state of the first arc groove and the second arc groove on the rotating shaft 211.

[0093] Exemplarily, a matching structure is adopted between the first clamping member 231 and the slideway, including but not limited to, the first clamping member 231 is formed with a sliding block and a sliding groove is opened on the slideway; or the cross-sections of the first clamping member 231 and the slideway are both square, so that the first clamping member 231 can only slide in the slideway and cannot rotate during sliding.

[0094] In some examples, such as Figures 4 to 6 As shown, the adjusting member 233 includes: a screw 2331, along the sliding conduction direction, the first clamping member 231 is provided with a threaded hole, the second clamping member 232 is provided with a blind hole, the screw 2331 is passed through the blind hole, and one end of the screw 2331 is threadedly connected to the threaded hole; a handle 2332 is arranged at one end of the screw 2331 away from the first clamping member 231; a limit member is arranged on the screw 2331, and is used to limit the handle 2332 from approaching the second clamping member 232.

[0095] In the above technical solution, the adjusting member 233 includes a screw, a handle 2332 and a stopper, wherein the screw 2331 is penetrated through the threaded hole of the first clamping member 231 and the blind hole of the second clamping member 232 along the conducting direction of the slideway, and the screw 2331 is connected to the first clamping member 231 through a thread, so that by rotating the screw 2331, the first clamping member 231 can be moved along the extending direction of the screw 2331, that is, along the extending direction of the slideway. The screw 2331 is provided with a handle 2332 at one end away from the first clamping member 231, and the handle 2332 can be more convenient for rotating the screw 2331. At the same time, a limit member is also provided on the screw 2331, and the limit member can limit the screw 2331 from approaching the second clamping member 232, thereby avoiding the phenomenon that the first clamping member 231 does not move when the screw 2331 is rotated, and the screw 2331 moves toward the second clamping member 232.

[0096] It is understandable that the limiting member may be disposed outside the box body 212 to abut against the surface of the box body 212 , or may be disposed outside the second clamping member 232 to abut against the outer surface of the second clamping member 232 .

[0097] It is understandable that the limit member and the screw rod 2331 can adopt an integrated structure to improve the structural strength.

[0098] In some examples, such as Figure 1 and Figure 3As shown, the support portion 220 includes: a leg 221 , one end of which is connected to the rotating shaft portion 210 ; and a support seat 222 , the other end of which is connected to the support seat 222 .

[0099] In the above technical solution, the support portion 220 includes a leg 221 and a support 222, wherein one end of the leg 221 is connected to the rotating shaft portion 210, and the other end of the leg 221 is connected to the support 222, so that the support 222 and the leg 221 can provide stable supporting force for the rotating shaft portion 210 and the tire mold assembly 100.

[0100] It is understandable that along the axial direction of the rotating shaft 211 , the tire mold assembly 100 and the rotating shaft portion 210 have a certain length, and the center of the support 222 can be located at the gravity center of the tire mold assembly 100 and the rotating shaft portion 210 to ensure the supporting stability of the support 222 .

[0101] In some examples, such as Figure 1 and Figure 3 As shown, the support portion 220 further includes a hanging point 223 disposed on the support 222 .

[0102] In the above technical solution, the support part 220 also includes a hanging point 223 arranged on the support 222, and the hanging point 223 is used to connect the sling to facilitate the movement of the thin-walled part welding device through the lifting equipment, which is beneficial to improve the flexibility of the thin-walled part welding device.

[0103] Exemplarily, a plurality of hanging point members 223 may be provided, and the plurality of hanging point members 223 are evenly arranged around the support 222 . Such an arrangement is beneficial to improving the stability of the thin-walled member welding device during the lifting process.

[0104] In some examples, such as Figure 1 and Figure 7 As shown, the clamping assembly 300 includes: a pressure plate portion 310, which is used to abut against the side of the components of the thin-walled parts away from the tire mold assembly 100; and a clamping portion 320, which is used to adjust the distance between the pressure plate portion 310 and the tire mold assembly 100.

[0105] In the above technical solution, the clamping assembly 300 includes a pressure plate portion 310 and a clamping portion 320, wherein the pressure plate portion 310 is used to abut against the thin-walled part, the pressure plate portion 310 and the tire mold assembly 100 are respectively located on both sides of the thin-walled part, and the clamping portion 320 is used to provide a force for the pressure plate portion 310 and the tire mold assembly 100 to approach each other, so that the pressure plate portion 310 is close to the tire mold assembly 100, and then the pressure plate portion 310 and the tire mold assembly 100 can clamp the various components of the thin-walled part.

[0106] It can be understood that the pressure plate portion 310 includes a plurality of pressure plates adapted to thin-walled components, such as: flange edge pressure plate 311, skin pressure plate, etc., and the area of ​​the pressure plate is smaller than the area of ​​the corresponding thin-walled component, so that when the pressure plate abuts against the thin-walled component, the connection between the various components of the thin-walled component can be located outside the range covered by the pressure plate, so as to facilitate welding processing.

[0107] It can be understood that, through the fixing method of the pressing plate portion 310 and the clamping portion 320, both sides of the thin-walled part can be fixed, which can further prevent the thin-walled part from being deformed, and is more conducive to ensuring the processing accuracy of the thin-walled part.

[0108] It is understandable that the clamping portion 320 includes a plurality of clamping members such as a U-shaped clamp and a screw. Figure 7 As shown, since some parts of the thin-walled part have mounting holes, such as the flange 910, corresponding holes can be opened on the tire mold assembly 100 and the flange pressure plate 311, threaded holes are opened on the tire mold assembly 100, and blind holes are opened on the flange pressure plate 311, so that screws can be used as clamping parts to adjust the distance between the flange pressure plate 311 and the tire mold assembly 100. At the same time, the use of screws as clamping parts also has a better positioning effect, which is beneficial to ensure that the positional relationship between the flange 910 of the thin-walled part, the flange pressure plate 311 and the tire mold assembly 100 is fixed to each other.
