Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a multi-angle adjustable robotic arm for composite welding. Background Technology

[0002] Hybrid welding combines the advantages of different welding processes and has been widely used in welding dissimilar materials and complex structural workpieces (such as automotive parts and aerospace components). However, this type of welding has extremely high requirements for the precision of the welding torch angle, workpiece adaptability, and work efficiency: it needs to cover welds from multiple directions; it needs to be adaptable to workpieces of different sizes and shapes; and it needs to balance the safety of the welding process with the cleanliness of the working environment.

[0003] Currently, existing welding robotic arms have the following drawbacks in composite welding scenarios: conventional clamps can only fix workpieces with regular shapes, and their clamping stability is insufficient for irregularly shaped workpieces or workpieces with structural gaps; moreover, it is difficult to adjust the angle synchronously after clamping, and it cannot cooperate with the welding torch for multi-angle operation.

[0004] Most robotic arms lack specific protective structures, allowing welding spatter to easily damage the welding torch or surrounding components; scattered welding slag leads to a dirty and messy working environment, increasing cleaning costs and safety hazards. Some equipment only supports a single welding process and cannot quickly switch to or adapt to the multi-process collaborative requirements of composite welding, necessitating multi-station switching and extending working hours. Summary of the Invention

[0005] To solve the above technical problems, the present invention is achieved through the following technical solution: a multi-angle adjustable robotic arm for composite welding, comprising: a support platform, wherein a welding adjustment arm is detachably installed on the top of the support platform for adjusting the welding point, and chip collection assemblies are symmetrically installed on both sides of the outer surface of the support platform. The column is used for stable support of the positioning clamp. The column is fixedly installed on both sides of the top of the chip collection assembly. A motor is fixedly installed on one side of the outer surface of the column. The positioning clamp is rotatably installed between the opposite sides of the column through the output end of the motor, and the positioning clamp is mounted on both sides of the welding adjustment arm. The welding adjustment arm includes a robotic arm rotary table. A main arm is rotatably mounted on the top of the rotary table. An arm linkage is internally driven by the main arm. A welding seat is fixedly mounted inside the arm linkage. A welding torch is fixedly mounted inside the welding seat. A protective cover is fitted onto the outer surface of the welding torch. The robotic arm rotary table of the welding adjustment arm is threaded to the top of the support platform. The main arm and arm linkage are reset to their initial positions, and the welding torch is in a ready-to-work state along with the welding seat. When welding a workpiece, the robotic arm rotary table drives the main arm to rotate horizontally, adjusting the horizontal position of the welding torch. The main arm and arm linkage, through their internal transmission structure, adjust the pitch and extension angles of the welding torch, aligning the welding torch with the workpiece welding area.

[0006] Preferably, the robotic arm rotary table is threadedly mounted on the top of the support platform, and the welding torch is mounted between the two positioning clamps via the robotic arm rotary table, main arm, and arm linkage.

[0007] Preferably, the protective component includes a sleeve, with an inner partition plate fixedly installed on the outer surface of the sleeve, a protrusion fixedly installed on the outer surface of the inner partition plate, and an isolation cover fitted onto the outer surface of the inner partition plate. During welding, the inner partition plate and protrusion plate of the protective component, together with the isolation cover, isolate welding spatter, reduce heat diffusion, and protect the welding torch and surrounding components. The isolation cover is designed with a conical structure, which can expand the protection range, extending outward from the end of the welding torch, blocking the high-temperature metal spatter generated during welding from directly splashing onto the welding torch body, welding seat, or surrounding components, avoiding burns and wear to components, and extending equipment life. The inclined surface of the conical isolation cover can guide some spatter to slide down along the conical surface into the chip collection assembly below, reducing the accumulation of spatter on the surface of the isolation cover.

[0008] Preferably, the sleeve, inner partition, and isolation cover are all fitted onto the outer surface of the welding torch. The isolation cover is a conical structure, and the protrusions are circumferentially mounted on the surface of the inner partition. The hollow space formed between the isolation cover and the inner partition can create an air buffer layer, reducing the efficiency of direct heat transfer from welding to the welding torch or surrounding structures, and reducing the risk of heat damage. The circumferential distribution of the protrusions on the surface of the inner partition increases the airflow area inside the isolation cover, allowing the heat generated during welding to be quickly conducted and dissipated through the protrusions, preventing localized overheating inside the isolation cover. Furthermore, when spatter comes into contact with the protrusions, it is dispersed, preventing a large amount of spatter from accumulating in one area. Simultaneously, the protrusions can block spatter from directly impacting the welding torch, further reducing the probability of the welding torch being damaged by spatter.

[0009] Preferably, the positioning clamp includes a frame, a positioning bracket is fixedly installed on the surface of the frame near the column, a positioning seat is fixedly installed on the outer surface of the positioning bracket, an extension platform is fixedly installed on the outer side of the frame, a push cylinder is fixedly installed inside the extension platform, and a clamping component is driven to the actuating end of the push cylinder. Before welding the workpiece, the operator starts the motor, which drives the positioning bracket to rotate the frame to a horizontal position or a suitable angle. The push cylinder then extends the telescopic rod, which in turn drives the clamping block to slide along the guide slider. The operator then places the workpiece between the clamping hook and the clamping block, and the push cylinder retracts to clamp the workpiece. The push cylinder, clamping block, and clamping hook work together to achieve rapid clamping of workpieces of different sizes and shapes, ensuring the positional stability of the workpiece during welding, and adapting to the angular rotation requirements of the positioning clamp, keeping the workpiece fixed during multi-directional welding.

[0010] Preferably, the positioning seat is fixedly connected to the outer surface of the motor, the output end of the motor is fixedly connected to the positioning frame, and the positioning frame drives the frame to rotate and be installed between the opposite surfaces of the column.

[0011] Preferably, the clamping component includes a guide slide block, a limit block fixedly mounted on the top of the guide slide block, a telescopic rod internally mounted on the guide slide block, a clamping block fixedly mounted on the outer surface of the telescopic rod, and a hook on the top of the clamping block. The positioning clamp is fixed to the motor via a positioning seat and can rotate with the motor output to adjust the workpiece angle. The actuator of the push cylinder is connected to the telescopic rod, extending and retracting to drive the clamping block to slide along the guide slide block, facilitating the adaptation to workpieces of different sizes. The clamping block is fixed to the telescopic rod and moves synchronously with the push cylinder, providing stable clamping force through rigid contact with the workpiece surface, preventing workpiece displacement during welding. The clamping block and hook work together to clamp irregularly shaped workpieces with protrusions or grooves. By embedding the hook into the gaps in the workpiece structure, a dual fixation of hooking and clamping is formed, preventing the workpiece from falling off due to welding vibration or angle adjustment.

[0012] Preferably, the telescopic rod is fixedly connected to the actuator of the push cylinder, and the clamping block is slidably adapted to the guide block via the telescopic rod.

[0013] Preferably, the chip collection assembly includes a collection seat with a through slot inside, positioning grooves on both sides of the top of the collection seat, a raised pad fixedly installed on the upper surface of the collection seat, and chip guide plates rotatably installed on both sides of the outer surface of the collection seat. During the welding process, small welding chips may fall directly onto the surface of the collection seat. The raised pad can buffer the impact of the welding chips and prevent them from directly impacting the collection seat and causing wear or deformation.

[0014] Preferably, the through slot is fixedly connected to the support platform, the positioning slot is fixedly connected to the column, and the chip guide plate is configured with an inclined structure and positioned below the positioning clamp. Welding chips fall onto the chip guide plate below the positioning clamp. The inclined structure of the chip guide plate allows for adjustment of the inclination angle according to the size of the workpiece and the welding angle, ensuring that welding chips from different positions are effectively guided. Simultaneously, the flip-up structure of the chip guide plate facilitates subsequent cleaning of accumulated welding chips within the collection seat; flipping the chip guide plate exposes the opening of the collection seat. The inclined structure of the chip guide plate allows the falling welding chips to slide naturally along the inclined surface towards the collection seat, preventing welding chips from accumulating below the positioning clamp, achieving centralized collection of welding chips, and reducing the workload of manual cleaning.

[0015] This invention provides a multi-angle adjustable robotic arm specifically for composite welding. It offers the following advantages: (i) The multi-angle adjustable robotic arm for composite welding is fixed to the motor by the positioning clamp and the positioning seat. It can rotate with the output end of the motor to adjust the angle of the workpiece. The actuator of the push cylinder is connected to the telescopic rod. By extending and retracting, the clamping block slides along the guide slide to adapt to workpieces of different sizes.

[0016] (II) This multi-angle adjustable robotic arm for composite welding is fixed by clamping blocks and telescopic rods, and moves synchronously with the push cylinder. Through rigid contact with the workpiece surface, it provides stable clamping force and prevents workpiece displacement during welding. The clamping blocks and hooks work together to clamp irregularly shaped workpieces with protrusions or grooves. By embedding the hooks into the gaps in the workpiece structure, a double fixation of hooking and clamping is formed, preventing the workpiece from falling off due to welding vibration or angle adjustment.

[0017] (III) This multi-angle adjustable robotic arm for composite welding features a conical isolation cover. This conical structure expands the protection range, extending outwards from the welding torch tip. It prevents high-temperature metal spatter generated during welding from directly impacting the welding torch body, welding base, or surrounding components, thus avoiding burns and wear and extending equipment life. The inclined surface of the conical isolation cover guides some of the spatter along the conical surface to the chip collection assembly below, reducing spatter accumulation within the isolation cover.

[0018] (iv) The multi-angle adjustable robotic arm for composite welding has protrusions distributed in a circumferential shape on the surface of the inner layer partition, which can increase the air circulation area inside the isolation cover. This allows the heat generated by welding to be quickly conducted and dissipated through the protrusions, avoiding local overheating inside the isolation cover. When the spatter comes into contact with the protrusions, it will be dispersed to prevent a large amount of spatter from accumulating in a certain area. At the same time, the protrusions can block the spatter from directly hitting the welding torch, further reducing the probability of the welding torch being damaged by spatter.

[0019] (V) This multi-angle adjustable robotic arm for composite welding uses a chip guide plate with an inclined structure to allow falling welding chips to slide naturally along the inclined surface to the collection seat, preventing welding chips from accumulating under the positioning clamp and achieving centralized collection of welding chips, thus reducing the workload of manual cleaning. During the welding process, small particles of welding chips may fall directly onto the surface of the collection seat. The raised pad can buffer the impact force of the welding chips and prevent them from directly hitting the collection seat and causing wear or deformation. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a multi-angle adjustable robotic arm for composite welding, comprising: a support platform 1, wherein a welding adjustment arm 3 is detachably installed on the top of the support platform 1, the welding adjustment arm 3 being used to adjust the welding point position, and chip collection assemblies 2 are symmetrically installed on both sides of the outer surface of the support platform 1. The column 5 is used to stably support the positioning clamp 4. The column 5 is fixedly installed on both sides of the top of the chip collection assembly 2. A motor 6 is fixedly installed on one side of the outer surface of the column 5. The positioning clamp 4 is rotatably installed between the opposite faces of the column 5 through the output end of the motor 6, and the positioning clamp 4 is mounted on both sides of the welding adjustment arm 3. The welding adjustment arm 3 includes a robotic arm rotary table 31. A main arm 32 is rotatably mounted on the top of the robotic arm rotary table 31. An arm connecting rod 34 is internally driven by the main arm 32. A welding seat 33 is fixedly mounted inside the arm connecting rod 34. A welding torch 35 is fixedly mounted inside the welding seat 33. A protective part 36 is fitted on the outer surface of the welding torch 35. The robotic arm rotary table 31 of the welding adjustment arm 3 is threaded to the top of the support platform 1. The main arm 32 and the arm connecting rod 34 are reset to their initial positions, and the welding torch 35 is in a ready-to-work state along with the welding seat 33. When welding a workpiece, the robotic arm rotary table 31 drives the main arm 32 to rotate horizontally, adjusting the horizontal position of the welding torch 35. The main arm 32 and the arm connecting rod 34 cooperate through an internal transmission structure to adjust the pitch and extension angles of the welding torch 35, so that the welding torch 35 is aligned with the welding area of ​​the workpiece.

[0024] The robotic arm rotary table 31 is threadedly mounted on the top of the support platform 1, and the welding torch 35 is driven between the two side positioning clamps 4 through the robotic arm rotary table 31, the main arm 32, and the arm connecting rod 34.

[0025] The protective component 36 includes a sleeve 364, on the outer surface of which an inner layer partition 361 is fixedly installed. A protrusion 363 is fixedly installed on the outer surface of the inner layer partition 361, and an isolation cover 362 is fitted over the outer surface of the inner layer partition 361. During welding, the inner layer partition 361 and protrusion 363 of the protective component 36, in conjunction with the isolation cover 362, isolate welding spatter, reduce heat diffusion, and protect the welding torch 35 and surrounding components. The isolation cover 362 is designed with a conical structure, which expands the protection range, extending outwards from the end of the welding torch 35. This prevents high-temperature metal spatter generated during welding from directly splashing onto the welding torch 35 body, welding seat 33, or surrounding components, avoiding burns and wear to the components and extending equipment life. The inclined surface of the conical isolation cover 362 guides some spatter to slide down along the conical surface into the chip collection assembly 2 below, reducing spatter accumulation within the isolation cover 362.

[0026] The sleeve 364, inner partition 361, and isolation cover 362 are all fitted onto the outer surface of the welding torch 35. The isolation cover 362 is a conical structure, and the protrusions 363 are circumferentially mounted on the surface of the inner partition 361. The hollow space formed between the isolation cover 362 and the inner partition 361 can form an air buffer layer, reducing the efficiency of direct heat transfer from welding to the welding torch 35 or surrounding structures, and reducing the risk of heat damage. The protrusions 363 are circumferentially distributed on the surface of the inner partition 361, which can increase the air circulation area inside the isolation cover 362, allowing the heat generated by welding to be quickly conducted and dissipated through the protrusions 363, avoiding local overheating inside the isolation cover. When spatter comes into contact with the protrusions 363, it will be dispersed, preventing a large amount of spatter from accumulating in a certain area. At the same time, the protrusions 363 can block spatter from directly impacting the welding torch 35, further reducing the probability of the welding torch 35 being damaged by spatter.

[0027] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8 As shown, the chip collection assembly 2 includes a collection seat 21. The collection seat 21 has a through slot 25 inside, and positioning grooves 24 on both sides of the top of the collection seat 21. A raised pad 23 is fixedly installed on the upper surface of the collection seat 21, and chip guide plates 22 are rotatably installed on both sides of the outer surface of the collection seat 21. During the welding process, small welding chips may fall directly onto the surface of the collection seat 21. The raised pad 23 can buffer the impact of the welding chips, preventing them from directly impacting the collection seat 21 and causing wear or deformation.

[0028] The through slot 25 is fixedly connected to the support platform 1, the positioning slot 24 is fixedly connected to the column 5, and the chip guide plate 22 is set with an inclined structure and is located below the positioning clamp 4. Welding chips generated during welding fall onto the chip guide plate 22 below the positioning clamp 4. The inclined structure of the chip guide plate 22 allows for adjustment of the tilt angle according to the size of the workpiece and the welding angle, ensuring that welding chips from different positions are effectively guided. Simultaneously, the flip-up structure of the chip guide plate 22 facilitates the later cleaning of accumulated welding chips in the collection seat 21; flipping the chip guide plate 22 exposes the opening of the collection seat 21. The inclined structure of the chip guide plate 22 allows the falling welding chips to slide naturally along the inclined surface towards the collection seat 21, preventing welding chips from accumulating below the positioning clamp 4, achieving centralized collection of welding chips, and reducing the workload of manual cleaning.

[0029] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 11As shown, the positioning clamp 4 includes a frame 41. A positioning frame 46 is fixedly installed on the surface of the frame 41 near the column 5. A positioning seat 43 is fixedly installed on the outer surface of the positioning frame 46. An extension platform 44 is fixedly installed on the outer side of the frame 41. A push cylinder 42 is fixedly installed inside the extension platform 44. A clamping component 45 is driven to the actuating end of the push cylinder 42. Before welding the workpiece, the operator starts the motor 6, which drives the positioning frame 46 to rotate the frame 41 to a horizontal position or a suitable angle. The push cylinder 42 drives the telescopic rod 453 to extend. At this time, the telescopic rod 453 drives the clamping block 455 to slide along the guide slider 451. Then, the operator places the workpiece between the hook 454 and the clamping block 455. The push cylinder 42 retracts to complete the workpiece clamping. The push cylinder 42, clamping block 455 and hook 454 work together to achieve quick clamping of workpieces of different sizes and shapes, ensuring the positional stability of the workpiece during welding, while adapting to the angular rotation requirements of the positioning clamp 4, so that the workpiece remains fixed during multi-directional welding.

[0030] The positioning seat 43 is fixedly connected to the outer surface of the motor 6, the output end of the motor 6 is fixedly connected to the positioning frame 46, and the positioning frame 46 drives the frame 41 to rotate and be installed between the opposite surfaces of the column 5.

[0031] The clamping component 45 includes a guide slide block 451, with a limit block 452 fixedly installed on the top of the guide slide block 451. A telescopic rod 453 is internally mounted on the guide slide block 451, and a clamping block 455 is fixedly installed on the outer surface of the telescopic rod 453. A hook 454 is provided on the top of the clamping block 455. The positioning clamp 4 is fixed to the motor 6 via a positioning seat 43 and can rotate with the output end of the motor 6 to adjust the workpiece angle. The actuator of the push cylinder 42 is connected to the telescopic rod 453, and by extending and retracting, it drives the clamping block 455 to slide along the guide slide block 451 to accommodate workpieces of different sizes. The clamping block 455 is fixed to the telescopic rod 453 and moves synchronously with the push cylinder 42. Through rigid contact with the workpiece surface, it provides a stable clamping force, preventing workpiece displacement during welding. The clamping block 455 and the hook 454 work together to clamp irregularly shaped workpieces with protrusions or grooves. The hook 454 is embedded in the gap of the workpiece structure to form a double fixation of hooking and clamping, which prevents the workpiece from falling off due to welding vibration or angle adjustment.

[0032] The telescopic rod 453 is fixedly connected to the actuating end of the push cylinder 42, and the clamping block 455 is slidably adapted to the guide block 451 through the telescopic rod 453.

[0033] In use, before welding the workpiece, the operator starts the motor 6, which drives the positioning frame 46 to rotate the frame 41 to a horizontal or suitable angle. The push cylinder 42 then extends the telescopic rod 453, causing the clamping block 455 to slide along the guide slider 451. The operator then places the workpiece between the hook 454 and the clamping block 455, and the push cylinder 42 retracts to clamp the workpiece. The push cylinder 42, clamping block 455, and hook 454 work together to quickly clamp workpieces of different sizes and shapes, ensuring the stability of the workpiece position during welding. Simultaneously, it adapts to the angular rotation requirements of the positioning frame 4, keeping the workpiece fixed during multi-directional welding.

[0034] The positioning clamp 4 is fixed to the motor 6 via the positioning seat 43 and can rotate with the output end of the motor 6 to adjust the workpiece angle. The actuator of the push cylinder 42 is connected to the telescopic rod 453, which extends and retracts to drive the clamping block 455 to slide along the guide slider 451, so as to adapt to workpieces of different sizes. The clamping block 455 is fixed to the telescopic rod 453 and moves synchronously with the push cylinder 42. Through rigid contact with the workpiece surface, it provides a stable clamping force and avoids workpiece displacement during welding. The clamping block 455 cooperates with the hook 454 to clamp irregularly shaped workpieces with protrusions or grooves. By embedding the hook 454 into the gap of the workpiece structure, a double fixation of hooking and clamping is formed to prevent the workpiece from falling off due to welding vibration and angle adjustment.

[0035] The robotic arm rotary table 31 of the welding adjustment arm 3 is fixed to the top of the support platform 1 by threads. The main arm 32 and the arm connecting rod 34 are reset to their initial positions, and the welding torch 35 is in a ready-to-work state along with the welding seat 33. When welding the workpiece, the robotic arm rotary table 31 drives the main arm 32 to rotate horizontally, adjusting the horizontal position of the welding torch 35. The main arm 32 and the arm connecting rod 34 cooperate through the internal transmission structure to adjust the pitch and extension angles of the welding torch 35, so that the welding torch 35 is aligned with the welding area of ​​the workpiece.

[0036] During welding, the inner partition 361 and protrusion 363 of the protective component 36, together with the isolation cover 362, isolate welding spatter, reduce heat diffusion, and protect the welding torch 35 and surrounding components. The isolation cover 362 is designed with a conical structure, which expands the protection range by extending outward from the end of the welding torch 35. This prevents high-temperature metal spatter generated during welding from directly splashing onto the welding torch 35 body, welding seat 33, or surrounding components, avoiding burns and wear to the components and extending the equipment life. The inclined surface of the conical isolation cover 362 can guide some of the spatter to slide down along the conical surface into the chip collection assembly 2 below, reducing the accumulation of spatter on the surface of the isolation cover 362.

[0037] The hollow space formed between the isolation cover 362 and the inner partition 361 can form an air buffer layer, reducing the efficiency of welding heat transfer to the welding torch 35 or surrounding structures and reducing the risk of heat damage. The protrusions 363 are distributed circumferentially on the surface of the inner partition 361, which can increase the air circulation area inside the isolation cover 362, allowing the heat generated by welding to be quickly conducted and dissipated through the protrusions 363, avoiding local overheating inside the isolation cover. When the spatter comes into contact with the protrusions 363, it will be dispersed to prevent a large amount of spatter from accumulating in a certain area. At the same time, the protrusions 363 can block the spatter from directly hitting the welding torch 35, further reducing the probability of the welding torch 35 being damaged by spatter.

[0038] Welding slag falls onto the guide plate 22 below the positioning clamp 4. The guide plate 22 is designed with an inclined structure, and its inclination angle can be adjusted according to the size of the workpiece and the welding angle to ensure that welding slag from different positions can be effectively guided. At the same time, the flip-up structure of the guide plate 22 facilitates the later cleaning of accumulated welding slag in the collection seat 21. Flipping the guide plate 22 exposes the opening of the collection seat 21. The inclined structure of the guide plate 22 allows the falling welding slag to slide naturally along the inclined surface to the collection seat 21, preventing the welding slag from accumulating below the positioning clamp 4, achieving centralized collection of welding slag, and reducing the amount of manual cleaning work.

[0039] During the welding process, small welding slag particles may fall directly onto the surface of the collection seat 21. The raised pad 23 can buffer the impact of the welding slag and prevent the welding slag from directly hitting the collection seat 21 and causing wear or deformation.
