Description

Technical Field

[0001] This invention belongs to the technical field of aluminum profile welding, and more specifically, relates to an integrated processing equipment for aluminum profiles. Background Technology

[0002] Aluminum profiles are widely used in rail transportation, building structures, new energy equipment, and industrial equipment due to their advantages such as light weight, high strength, and good corrosion resistance. In actual production, it is often necessary to butt-weld the ends of two aluminum profiles to form a continuous structure or meet assembly requirements. The existing technology for welding aluminum profiles still has the following drawbacks: In the existing technology, the space at the end of aluminum profiles is limited, and traditional clamps cannot provide enough space for welding operations while ensuring clamping strength, which can easily lead to interference between the clamping mechanism and the welding mechanism.

[0003] In existing technologies, the alignment of aluminum profile ends before welding often relies on manual labor or simple limiting structures, which makes it difficult to achieve high-precision self-centering positioning and results in unstable welding end-face contact quality.

[0004] In existing technologies, the ends of aluminum profiles will undergo thermal expansion due to instantaneous temperature rise during resistance pressure welding. If a completely rigid clamping method is used, it can easily lead to deformation of thin-walled aluminum profiles, reduced weld quality, or even welding failure.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an integrated processing equipment for aluminum profiles in order to achieve a more practical and valuable purpose. Summary of the Invention

[0006] This invention provides an integrated processing equipment for aluminum profiles, which overcomes the above-mentioned defects in the prior art.

[0007] The purpose and effectiveness of this integrated processing equipment for aluminum profiles are achieved by the following specific technical means: An integrated processing device for aluminum profiles includes a frame 10 and a welding actuator disposed on the frame 10, and further includes: The processing cylinder 12 is disposed on the frame 10 and is used to accommodate and position the ends of at least two aluminum profiles to be welded. The processing cylinder 12 has an avoidance opening 13 on the upper side of the middle part. The first clamping assembly is disposed inside the processing cylinder 12 and is used to radially clamp the aluminum profile. The first clamping assembly includes a first annular frame 16 and a first limiting member 18 symmetrically disposed inside the first annular frame 16 to self-center and position the end of the aluminum profile during the clamping process. At least one side of the first clamping assembly is elastically floating with the elastic pre-tightening member 51 through the first support member 22 to allow the aluminum profile to undergo thermal displacement during the welding process. The second clamping assembly is disposed inside the processing cylinder 12. The second clamping assembly includes a second annular frame 32, a second push block 33, a connector 34, and a second support 37. Under radial driving action, the second push block 33 generates axial displacement through the connector 34 to push the welding ends of the two aluminum profiles to be connected to each other.

[0008] In this design, the first clamping assembly is used for radial clamping and has elastic floating capability, while the second clamping assembly is used for axial docking. The welding actuator enters the welding area through the clearance opening. Even with limited end space, this design achieves precise pre-welding positioning of the aluminum profile, stable clamping during welding, and ensures that welding operations do not interfere with each other, guaranteeing the stability and consistency of resistance pressure welding.

[0009] Preferably, the first limiting member 18 has a V-shaped or V-shaped structure, and can achieve self-centering positioning by contacting the aluminum profile with symmetrical inclined surfaces.

[0010] In this solution, the geometric self-guiding characteristics of the first limiting member 18 are used to achieve automatic centering of the aluminum profile end, reduce manual centering errors, and improve welding accuracy.

[0011] Preferably, the first clamping assembly further includes a first clamping plate 20, which is disposed within the first annular frame 16 via the first support member 22 and is used to clamp the outer side of the aluminum profile.

[0012] This solution achieves radial clamping of the outer side of the aluminum profile, improving the overall stability of the aluminum profile during the welding process.

[0013] Preferably, one side of the first support member 22 is rigidly connected to the first annular frame 16, and the other side is elastically connected through the elastic preload member 51 to form a combination structure of rigid clamping and floating clamping.

[0014] In this solution, welding heat deformation is absorbed without reducing the clamping force, thus avoiding deformation of thin-walled aluminum profiles or unstable welding quality due to rigid clamping.

[0015] Preferably, the first clamping assembly further includes an inner support member 25, which can extend into the groove of the aluminum profile to support the cavity structure of the aluminum profile.

[0016] In this solution, the cavity structure is internally supported while being clamped on the outside to prevent the thin-walled aluminum profile from collapsing or becoming locally unstable during clamping or welding.

[0017] Preferably, the second clamping assembly further includes an expandable member 40, which is driven by an air pump 41 to apply a radial stabilizing force to the second support member 37 and the second clamping plate 38.

[0018] In this solution, a stable and controllable axial connection force is provided for the two aluminum profiles, so that the welding ends always remain in contact before welding.

[0019] Preferably, the second push block 33 is connected to the second annular frame 32 via a connector 34, the connector 34 being used to convert the radial displacement of the second push block 33 into a butt displacement along the axial direction of the aluminum profile.

[0020] Preferably, the second support member 37 and the second clamping plate 38 are disposed on the second push block 33, and are used to contact the outer side of the aluminum profile and remain stable under the action of the axial docking displacement.

[0021] Preferably, the processing cylinder 12 is provided with a rotating ring 14, which meshes with a first gear 44 and a second gear 46 and is driven by a stepper motor 45 to drive the aluminum profile to rotate synchronously.

[0022] Preferably, the welding actuator is a resistance pressure welder 49, which is mounted on the frame 10 via a moving mechanism 48 and is capable of displacement adjustment in at least two directions relative to the processing cylinder 12.

[0023] Compared with the prior art, the present invention has the following beneficial effects: This invention enables aluminum profiles to automatically achieve end self-centering during clamping by incorporating a first clamping assembly with a symmetrical limiting structure within the processing cylinder. Specifically, the first limiting members in the first clamping assembly are symmetrically arranged and have an inclined guide structure. When the clamping assembly retracts radially, the inclined surface synchronously contacts the outer contour of the aluminum profile and generates a guiding effect, thereby forcing the aluminum profile to automatically move towards the geometric center position in the radial direction, achieving self-centering positioning without manual adjustment.

[0024] This invention employs a rigid-one-rigid clamping structure in the first clamping assembly. After the first clamp fully clamps the aluminum profile, one side of the clamping structure serves as a rigid positioning reference, while the other side clamping structure forms a radially floating clamping relationship with the support through an elastic preload member. Before welding, the elastic preload member provides a stable clamping force to the floating clamping structure, ensuring the aluminum profile remains reliably fixed in the initial welding state. During welding, when the end of the aluminum profile experiences instantaneous heating and slight thermal expansion due to resistance pressure welding, the floating clamping structure can retract within the allowable stroke range of the elastic preload member, thereby releasing the local stress caused by thermal expansion. After welding is completed and cooled, the elastic preload member drives the floating clamping structure to automatically reset. Through the above-mentioned structural and motion coordination, this invention avoids the problems of deformation, collapse, or unstable weld quality of thin-walled aluminum profiles caused by the inability to release thermal stress during welding, which is a problem with traditional rigid clamping methods. It achieves adaptive compensation for welding thermal deformation without losing clamping force, significantly improving the stability of the welding process and the yield of finished products.

[0025] This invention achieves stable axial connection of the welded ends of aluminum profiles by setting a second clamping assembly independent of the radial clamping mechanism. The second clamping assembly includes a second push block, a connecting member, a second support member, and an expandable member driven by an air pump. During operation, the expandable member is only used to apply a radial stabilizing force to the second clamping assembly and does not directly generate an axial connection force on the welded ends of the aluminum profiles. Specifically, during the process of the first clamping assembly radially clamping the aluminum profile and completing self-centering positioning, the first limiting member moves closer to the other through a telescopic rod, thereby driving the second limiting member to move closer to the other, which in turn pushes the second push block to produce a radial inward displacement. The radial displacement of the second push block is converted into a butt joint displacement along the axial direction of the aluminum profile through a connector disposed between the second push block and the second annular frame, so that the welded ends of the two aluminum profiles move closer to each other in the axial direction and remain in a fitted state. Simultaneously, the air pump supplies air to the expandable component, causing it to expand radially. This expands the component and applies a radial force to the second support and its second clamping plate, ensuring that the second clamping plate contacts the outer side of the aluminum profile before axial connection, thus providing pre-fitting and stable support. Through this structural and dynamic coordination, the aluminum profile is effectively constrained in the radial direction during axial connection, preventing radial offset, local warping, or unstable posture during end connection. During the docking process, the axial docking force is generated continuously and controllably by the structural relationship of the connectors, rather than being directly applied by the expandable parts. This makes the axial docking action and the radial stabilization action independent of each other in terms of the source and direction of force, while also cooperating with each other. This makes the axial docking process smoother, avoids the generation of impact loads, and effectively improves the fit quality and welding consistency of the welded end faces. It is especially suitable for welding scenarios of thin-walled hollow aluminum profile ends where high welding quality stability is required. Attached Figure Description

[0034] See attached document Figure 1 To be continued Figure 15 The system includes a frame 10 and a welding actuator mounted on the frame 10, and also includes: The processing cylinder 12 is mounted on the frame 10 and is used to accommodate and position the ends of at least two aluminum profiles to be welded. An avoidance opening 13 is provided on the upper side of the middle part of the processing cylinder 12. The first clamping assembly is disposed inside the processing cylinder 12 and is used to radially clamp the aluminum profile. The first clamping assembly includes a first annular frame 16 and a first limiting member 18 symmetrically disposed inside the first annular frame 16.

The second clamping assembly is disposed inside the processing cylinder 12. The second clamping assembly includes a second annular frame 32, a second push block 33, a connector 34, and a second support 37.

[0035] In practice, after the aluminum profile is placed into the processing cylinder 12, the first clamping component retracts radially to achieve self-centering clamping; the second clamping component advances axially to bring the welding ends of the two aluminum profiles together; during welding, the welding actuator, driven by the moving mechanism 48, approaches the welding end through the clearance opening 13 to perform resistance pressure welding, while maintaining the clamping state. Even with limited end space, this achieves precise pre-welding positioning of the aluminum profile, stable clamping during welding, and prevents interference between welding operations, ensuring the stability and consistency of resistance pressure welding.

[0044] Preferred options are shown in the appendix. Figure 7 Appendix Figure 9 Appendix Figure 14 Appendix Figure 15 An expandable member 40 is provided between the other end of the second support member 37 and the other side of the interior of the second housing 36. A third rubber member 39 is provided on one side of the second clamping plate 38. An air pump 41 is installed on the inner wall of the rotating ring 14. The air pump 41 is connected to the expandable member 40 by a telescopic connecting pipe 42.

[0045] Preferred options are shown in the appendix. Figure 7 To be continued Figure 9 A telescopic rod 31 is provided between the second limiting member 35 and the first limiting member 18, and the second limiting member 35 has a V-shaped structure.

[0046] Specific usage of this invention: The staff put two aluminum profiles into the processing cylinder 12 from both ends, so that the two aluminum profiles are located in the two rotating rings 14 respectively, and the placement parts 15 set in the rotating rings 14 support the aluminum profiles, so that the welded ends of the two aluminum profiles are located in the middle area of ​​the processing cylinder 12 and correspond to each other.

[0047] Subsequently, the system controls the two extended ends of the bidirectional telescopic cylinder 29 to extend synchronously, pushing the two movable rings 27 away from each other axially. Since one end of the first push block 17 slides in the inclined groove 28 within the movable ring 27, when the movable ring 27 undergoes axial displacement, under the inclined guiding action of the groove 28, the axial movement of the movable ring 27 is converted into the radial inward movement of the first push block 17, thereby bringing the pair of first push blocks 17 closer together. The closer proximity of the pair of first push blocks 17 drives the pair of first limiting members 18 to move closer together. Because the first limiting member 18 has a V-shaped structure, its inclined surface contacts the outer contour of the aluminum profile during the approach process, guiding the aluminum profile and causing it to gradually move towards the center position, thus confining the aluminum profile between the four limiting ends of the two first limiting members 18, achieving self-centering positioning of the aluminum profile end.

[0048] Simultaneously, as the first limiting member 18 approaches, it causes the first housing 19, the first support member 22, and the first clamping plate 20 to move closer to the aluminum profile. The first clamping plate 20 contacts the outer side of the aluminum profile and radially clamps it. When the first clamping plate 20 is blocked by the outer side of the aluminum profile, the first limiting member 18 and the first housing 19 continue to move closer, causing the first support member 22 to slide relative to the first housing 19 and stretching the first buffer member 23. Thus, the first buffer member 23 provides a continuous elastic clamping force to the first support member 22 and the first clamping plate 20, achieving stable clamping of the outer side of the aluminum profile.

[0049] A stable axial connection of the welded ends of the aluminum profile is achieved by setting a second clamping assembly independent of the radial clamping mechanism. The second clamping assembly includes a second push block 33, a connector 34, a second support 37, and an expandable component 40 driven by an air pump 41. During operation, the expandable component 40 is only used to apply a radial stabilizing force to the second clamping assembly and does not directly generate an axial connection force for the welded ends of the aluminum profile.

[0050] Specifically, during the process of the first clamping assembly radially clamping the aluminum profile and completing self-centering positioning, the first limiting member 18, when approaching each other, drives the second limiting member 35 to approach each other through the telescopic rod 31, thereby pushing the second push block 33 to generate radial inward displacement. The radial displacement of the second push block 33 is converted into a butt joint displacement along the axial direction of the aluminum profile through the connecting member 34 disposed between the second push block 33 and the second annular frame 32, so that the welded ends of the two aluminum profiles approach each other in the axial direction and maintain a fitted state.

[0051] Simultaneously, the air pump 41 supplies air to the expandable component 40, causing it to expand radially. This expands the component and applies a radial force to the second support component 37 and its second clamping plate 38, ensuring that the second clamping plate 38 contacts the outer side of the aluminum profile before axial connection, thus providing pre-fitting and stable support. Through this combination of structure and motion, the aluminum profile is effectively constrained in the radial direction during axial connection, preventing radial offset, local warping, or unstable posture at the welded ends.

[0052] During the docking process, the axial docking force is generated continuously and controllably by the structural relationship of the connector 34, rather than being directly applied by the expandable component 40. This makes the axial docking action and the radial stabilization action independent of each other in terms of the source and direction of force, while also cooperating with each other. This makes the axial docking process smoother, avoids the generation of impact loads, and effectively improves the fit quality and welding consistency of the welding end face. It is especially suitable for welding scenarios of thin-walled hollow aluminum profile ends where high welding quality stability is required.

[0053] During the continuous clamping process of the first clamping assembly, the first clamping plate 20 is subjected to the reaction force from the outside of the aluminum profile, causing the inner support member 25 to slide relative to the opening 24 and gradually enter the cavity or groove of the aluminum profile. The inner support member 25 and the second rubber member 26 on it support the internal structure of the aluminum profile, thereby forming a clamping structure in which the external limiting of the first limiting member 18 and the internal support of the inner support member 25 cooperate, further improving the structural stability of the thin-walled hollow aluminum profile during the clamping and welding process.

[0054] After the first clamping assembly has fully clamped the aluminum profile, one end of one of the first support members 22 contacts the inner side of the first housing 19 to form a rigid positioning reference; one end of the other first support member 22 is connected to the first housing 19 through an elastic preload member 51, and the first support member 22 has rubber blocks 50 on both sides of its end inside the first housing 19, allowing the first support member 22 to generate restricted radial floating within the first housing 19. This causes the corresponding first clamping plate 20 to form a floating gripper, while the other first clamping plate 20 forms a positioning gripper. Thus, before welding, the elastic preload member 51 provides a stable clamping force; during welding, the slight expansion of the aluminum profile end due to heat is allowed to be released; and after welding is completed and cooled, the elastic preload member 51 drives the gripper to automatically reset, achieving a floating compensation clamping effect.

[0055] After clamping and docking are completed, the system controls the stepper motor 45 to start. The stepper motor 45 drives the first gear 44 to rotate through the second gear 46, thereby driving the rotating ring 14 to rotate, so that the two aluminum profiles rotate synchronously. Subsequently, the moving mechanism 48 drives the resistance pressure welder 49 to move horizontally and vertically, so that the welding end of the resistance pressure welder 49 contacts the welding ends of the two aluminum profiles through the clearance opening 13, and completes the resistance pressure welding of the aluminum profile ends. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
