Description

Technical Field

[0001] This utility model relates to the field of hardware fitting welding technology, and more specifically, it relates to a welding device for processing hardware fittings. Background Technology

[0002] Against the backdrop of the rapid development of modern manufacturing, hardware accessories are an indispensable component in fields such as machinery, furniture, construction, and electronic products. Their processing quality and efficiency directly affect the performance and reliability of end products. Welding, as a key process in hardware accessory processing, has a decisive impact on product quality due to its operational precision and stability. However, from the perspective of process equipment design and processing efficiency, there are still technical problems that need to be solved in traditional welding equipment for hardware accessory processing.

[0003] Firstly, traditional welding equipment for hardware parts processing has significant shortcomings in workpiece clamping. Existing welding equipment typically uses a simple cylinder-driven single clamping plate structure to fix the workpiece. While this single-point or double-point clamping method can meet basic needs for workpieces with regular shapes, the hardware parts industry offers a wide variety of products, with most parts exhibiting irregular geometric shapes, complex curved surfaces, or irregular contours. When these irregularly shaped hardware parts are placed on traditional clamping devices, the limited number of contact points often prevents the formation of stable multi-point support between the workpiece and the clamping surface. This leads to the workpiece easily tilting, shaking, or shifting during clamping. This unstable clamping state makes it difficult to guarantee the accuracy of weld point positions during subsequent welding, resulting in inconsistent weld quality and severely impacting product qualification rates. In the welding processing of high-precision hardware parts, the inaccurate positioning caused by this simple clamping method is particularly prominent, not only increasing the scrap rate but also reducing production efficiency.

[0004] Secondly, in response to the above problems, some improved hardware welding devices have indeed appeared on the market, which superficially achieve the function of multi-point fixing of irregular hardware parts. However, these improved designs still reveal serious stability problems in practical applications: their multi-point clamping structure usually lacks a precise locking mechanism and anti-loosening design. When the welding device is subjected to factors such as vibration interference during operation, these simply connected clamping components are very easy to loosen or shift, causing the stability of the clamping device to gradually decrease. The originally adjusted multi-point clamping position shifts, resulting in the inability to guarantee the clamping accuracy of subsequent workpieces. More seriously, in some high-precision and high-requirement hardware welding operations, the slight displacement of the clamping device may cause the weld point to deviate from the design position, resulting in poor welding. This not only wastes materials but may also cause safety hazards to the end product due to insufficient welding strength. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a welding device for processing hardware accessories, so as to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a welding device for processing hardware accessories, comprising a rotary table, a placement platform fixedly mounted on the rotary table, movable seats movably mounted on both sides of the placement platform, a movable sleeve fixedly mounted on one side of the movable seat, a control sleeve rotatably mounted on the outer side of the movable sleeve, a drive wheel fixedly connected to one side of the control sleeve, an mounting plate fixedly mounted on the outer side of the movable sleeve, a threaded sleeve rotatably mounted on the mounting plate, a driven wheel fixedly connected to one side of the threaded sleeve, a plurality of driven wheels respectively meshing with the drive wheel, a control groove inclinedly opened on the inner side of the movable sleeve, and a control plate slidably mounted in the control groove. A fastening block is fixedly connected to one side of the control panel. Multiple clamping rods are slidably arranged inside the movable sleeve. A linkage sleeve is movably arranged inside the movable sleeve. A control sleeve is rotatably connected to one side of the movable sleeve. The inner wall of the control sleeve and the outer wall of the linkage sleeve are movably connected by threads. Multiple positioning blocks are movably arranged on one side of the control sleeve. A movable spring is connected to one side of the positioning block. The two ends of the movable spring are respectively connected to two adjacent positioning blocks. Multiple cylindrical blocks are fixedly arranged on the outer side of the movable sleeve. A positioning sleeve is slidably arranged on the outer side of the movable sleeve. A screw is fixedly connected to one side of the positioning sleeve. The outer wall of the screw is movably connected to the inner wall of the screw sleeve by threads.

[0009] The present invention is further configured such that a base is provided below the rotating table, and a geared motor is detachably provided on the inner side of the base. The output end of the geared motor passes through the top of the base and is connected to the rotating table. Through this structural design, the device can flexibly adjust the angle of the hardware accessories, which is convenient for welding different positions.

[0010] The present invention is further configured such that a slide rail is fixedly provided on the rotating platform, the movable seat is slidably mounted on the slide rail, a cylinder is detachably provided on the rotating platform, a piston rod is connected to the output end of the cylinder, and the other end of the piston rod is detachably connected to the movable seat. This design allows the clamping mechanism to move smoothly on the slide rail, and the cylinder provides a stable thrust to ensure accurate positioning during clamping, effectively avoiding errors that may be caused by manual adjustment.

[0011] The present invention is further configured such that a lifting assembly is detachably provided on the base, a moving assembly is detachably provided at the top of the lifting assembly, and a welding torch assembly is detachably provided on the moving assembly. This structure realizes the multi-dimensional adjustment function of the welding torch position, and the height and position of the welding torch can be flexibly adjusted according to the shape of different hardware accessories and welding requirements.

[0012] The present invention is further configured such that a positioning wheel is rotatably mounted on one side of the positioning block, and the positioning wheel is engaged between two adjacent cylindrical blocks, thus forming a mechanical interlocking mechanism.

[0013] The present invention is further configured such that a plurality of positioning rails are fixedly provided on one side of the control sleeve, and a positioning groove is provided in the positioning block. The positioning block is slidably installed on the outside of the positioning rails through the positioning groove. This guiding sliding structure ensures the accuracy of the positioning block movement and avoids offset during the positioning process.

[0014] The present invention is further configured such that a fixed plate is fixedly provided on the inner side of the movable sleeve, a top plate is fixedly connected to one end of the clamping rod, and a tension spring is movably sleeved on the outer side of the clamping rod. The two ends of the tension spring are respectively connected to the top plate and the fixed plate, and the clamping rod slides through the fixed plate. This elastic clamping structure allows the clamping rod to adapt to different surfaces of irregularly shaped hardware parts, and the tension spring provides appropriate clamping force, which not only ensures the clamping firmness but also avoids deformation and damage to the workpiece.

[0015] The present invention is further configured such that a linkage groove is provided on one side of the linkage sleeve, and a linkage block is fixedly connected to one side of the fastening block. The linkage block slides in the linkage groove, and this linkage mechanism realizes the synchronous locking function of the clamping system.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a welding device for processing hardware accessories, which has the following advantages:

[0018] 1. Through the structural design of components such as the moving sleeve, clamping rod, control sleeve, fastening block, and linkage sleeve, this device successfully solves the technical problem of traditional welding devices for hardware parts processing being unable to achieve multi-point clamping of irregularly shaped hardware parts. The device utilizes the organic cooperation of the moving seat, moving sleeve, clamping rod, and fastening block to form a highly flexible adaptive multi-point clamping system. When the irregularly shaped hardware part is placed on the placement table, the cylinder pushes the moving seat through the piston rod, causing the entire clamping mechanism to move inward. The clamping rod in contact with the hardware part automatically stops advancing, while the other clamping rods continue to advance until they all contact the workpiece surface. The tension springs are stretched to different degrees, thus achieving all-round multi-point support and clamping of hardware parts with various irregular geometric shapes, complex curved surface structures, or irregular contour features. This adaptive clamping method ensures that the workpiece remains stable during welding, without tilting, shaking, or displacement, thereby significantly improving the accuracy of the weld point position and the weld quality, greatly reducing the scrap rate, and increasing production efficiency. It is especially suitable for welding high-precision hardware parts, completely overcoming the problems of inaccurate positioning caused by traditional clamping methods.

[0019] 2. A multi-locking mechanism, formed by the cooperation of components such as a positioning sleeve, positioning block, positioning wheel, cylindrical block, control sleeve, driving wheel, driven sleeve, screw sleeve, and screw, solves the technical defect of insufficient stability in the connection structure of existing improved hardware welding devices. This design innovatively integrates multiple locking protection mechanisms: First, the positioning rail drives the positioning block and positioning wheel to rotate to the position corresponding to the cylindrical block through the positioning groove. The movable spring resets and pulls the positioning block, causing the positioning wheel to re-lock between the two cylindrical blocks, forming the first layer of locking. Then, the control sleeve rotates in the opposite direction, driving the screw sleeve to rotate, causing the screw to move and reset the positioning sleeve. The inner wall of the positioning sleeve limits the movement of the outer wall of the positioning wheel. To prevent the positioning wheel and positioning block from sliding outward, a second layer of locking is formed. Finally, the positioning wheel and cylindrical block cooperate to limit the movement, forming a third layer of locking to ensure that the control sleeve cannot rotate unexpectedly. This multi-locking mechanism can maintain high stability under the influence of factors such as vibration interference generated during the operation of the welding device, effectively preventing the clamping parts from loosening or shifting, ensuring that the adjusted multi-point clamping position will not deviate, and guaranteeing clamping accuracy even in high-precision and high-requirement hardware welding operations. This avoids the weld point deviating from the design position and forming poor welding, greatly reducing material waste, and preventing potential safety hazards to the end product caused by insufficient welding strength.

A control groove 10 is inclinedly opened on the inner side of the movable sleeve 4, a control plate 11 is slidably mounted in the control groove 10, and a fastening block is fixedly connected to one side of the control plate 11. 12. Multiple clamping rods 13 are slidably provided inside the movable sleeve 4. A linkage sleeve 14 is movably provided inside the movable sleeve 4. A control sleeve 15 is rotatably connected to one side of the movable sleeve 4. The inner wall of the control sleeve 15 is movably connected to the outer wall of the linkage sleeve 14 by threads. Multiple positioning blocks 16 are movably provided on one side of the control sleeve 15. A movable spring 17 is connected to one side of the positioning block 16. The two ends of the movable spring 17 are respectively connected to two adjacent positioning blocks 16. Multiple cylindrical blocks 18 are fixedly provided on the outer side of the movable sleeve 4. A positioning sleeve 19 is slidably provided on the outer side of the movable sleeve 4. A screw 20 is fixedly connected to one side of the positioning sleeve 19. The outer wall of the screw 20 is movably connected to the inner wall of the screw sleeve 8 by threads.

[0030] A base 21 is provided below the rotary table 1. A geared motor 22 is detachably provided inside the base 21. The output end of the geared motor 22 passes through the top of the base 21 and is connected to the rotary table 1.

[0031] A slide rail 23 is fixedly installed on the rotary table 1, and a movable seat 3 is slidably installed on the slide rail 23. A cylinder 24 is detachably installed on the rotary table 1, and a piston rod 25 is connected to the output end of the cylinder 24. The other end of the piston rod 25 is detachably connected to the movable seat 3.

[0032] A lifting assembly 26 is detachably mounted on the base 21, a moving assembly 27 is detachably mounted on the top of the lifting assembly 26, and a welding torch assembly 28 is detachably mounted on the moving assembly 27.

[0033] In this embodiment, when the equipment is needed, the irregularly shaped hardware parts to be welded are first placed on the placement table 2. Then, the clamping components are unlocked, and then the two cylinders 24 are opened simultaneously. This causes the piston rods 25 connected to the output ends of the cylinders 24 to push the moving seat 3, which in turn drives the moving sleeve 4 and other components to slide inward along the slide rail 23. After the hardware parts are clamped, the clamping components are locked again. Then, the cylinders 24 are closed, and then the lifting assembly 26 is opened. This causes the lifting assembly 26 to drive the upper moving assembly 27 and the welding torch assembly 28 to perform welding. After adjusting the height to a suitable level, turn off the lifting assembly 26, then turn on the moving assembly 27 and adjust the longitudinal position of the welding gun assembly 28. After adjusting the position to a suitable level, turn off the moving assembly 27. Then, the clamped hardware parts can be welded using the welding gun assembly 28. You can also turn on the reduction motor 22 to drive the rotary table 1 connected to the output end to rotate. The rotary table 1 will drive the placement platform 2 and the clamped hardware parts above to rotate, thereby adjusting the angle of the hardware parts. After adjusting to a suitable level, turn off the reduction motor 22.

[0034] Please see Figures 3-5 As a further implementation of the overall equipment: a positioning wheel 29 is rotatably installed on one side of the positioning block 16, and the positioning wheel 29 is engaged between two adjacent cylindrical blocks 18.

[0035] Multiple positioning rails 30 are fixedly provided on one side of the control sleeve 15, and a positioning groove 31 is provided in the positioning block 16. The positioning block 16 is slidably installed on the outside of the positioning rails 30 through the positioning groove 31.

[0036] A fixed plate 32 is fixedly provided on the inner side of the movable sleeve 4. A top plate 33 is fixedly connected to one end of the clamping rod 13. A tension spring 34 is movably sleeved on the outer side of the clamping rod 13. The two ends of the tension spring 34 are respectively connected to the top plate 33 and the fixed plate 32, and the clamping rod 13 slides through the fixed plate 32.

[0037] A linkage groove 35 is provided on one side of the linkage sleeve 14, and a linkage block 36 is fixedly connected to one side of the fastening block 12. The linkage block 36 slides in the linkage groove 35.

[0038] More specifically, when it is necessary to unlock the clamping component, firstly, the control sleeve 5 is rotated forward. The control sleeve 5 will drive the driving wheel 6 on one side to rotate forward. Then, the driving wheel 6 will drive the driven wheel 9 meshing with it to rotate in the opposite direction. Then, the driven wheel 9 will drive the screw sleeve 8 to rotate in the opposite direction on the mounting plate 7. Then, the screw 20 will drive the positioning sleeve 19 to slide, so that the positioning sleeve 19 no longer limits the outer wall of the positioning wheel 29. Then, the control sleeve 15 is rotated forward. The control sleeve 15 will drive the positioning rail 30 on one side to rotate forward. Then, the positioning rail 30 will drive the positioning block 16 to rotate forward through the positioning groove 31. Then, the positioning block 16 will drive the positioning wheel 29 on one side to move out from between the two cylindrical blocks 18, and the positioning wheel 29 will drive the positioning... Block 16 slides outward along the positioning rail 30 and positioning groove 31, causing the positioning block 16 to pull the positioning spring outward. Simultaneously, because the inner wall of the control sleeve 15 and the outer wall of the linkage sleeve 14 are connected by threads, and because the linkage block 36 and linkage groove 35 limit the linkage sleeve 14, the linkage sleeve 14 will not rotate. Then, the linkage sleeve 14, through the cooperation of the linkage groove 35 and linkage block 36, drives the fastening block 12 to slide, causing the fastening block 12 to drive one side of the control plate 11 to slide along the inclined control groove 10. Then, the control plate 11 will drive the fastening block 12 to slide outward, causing the fastening block 12 to drive one side of the linkage plate to slide outward along the linkage groove 35. Then, the inner wall of the fastening block 12 no longer clamps the outer wall of the clamping rod 13. When the air... When cylinder 24 drives piston rod 25 to move moving seat 3, moving seat 3 will drive moving sleeve 4 and other components to move inward. Then, clamping rod 13, which is in contact with the outer wall of the irregular hardware workpiece, will stop moving. Then, clamping rod 13 will slide relative to the inner side of linkage sleeve 14 and fixed plate 32. Then, moving sleeve 4 will drive fixed plate 32 to move, so that fixed plate 32 will drive tension spring 34 to stretch. When one end of all clamping rods 13 is in contact with the outer wall of the irregular hardware, tension spring 34 will be stretched to different degrees. Then, cylinder 24 will be closed. When it is necessary to lock the clamping components, first rotate control sleeve 15 in the opposite direction. Control sleeve 15 will drive positioning block 16 and positioning wheel 29 through the cooperation of positioning rail 30 and positioning groove 31 on one side. Spring 17 rotates in the opposite direction, and simultaneously, linkage sleeve 14 slides in the opposite direction, causing linkage sleeve 14 to push one side fastening block 12 to slide in the opposite direction. Then, fastening block 12 will drive one side control plate 11 to slide in the opposite direction in control groove 10. Due to the inclined opening of control groove 10, control plate 11 will drive one side fastening block 12 to converge inward, causing fastening block 12 to drive one side linkage block 36 to slide inward along linkage groove 35. Then, the inner wall of fastening block 12 will press against the outer wall of clamping rod 13 again, so that clamping rod 13 will not move. At this time, positioning rail 30 will drive positioning block 16 and positioning wheel 29 to the position corresponding to the original two cylindrical blocks 18 through positioning groove 31. Then, movable spring 17 will reset and pull positioning block 16.The positioning block 16 causes one side of the positioning wheel 29 to slide inward along the positioning rail 30 and positioning groove 31, allowing the positioning wheel 29 to re-engage between the two original cylindrical blocks 18. Then, the control sleeve 5 is rotated in the reverse direction, causing some of the drive wheels 6 to rotate in the reverse direction. The drive wheels 6 then drive the driven wheels 9 that mesh with them to rotate in the forward direction. The driven wheels 9 then drive the screw sleeve 8 to rotate in the forward direction on the mounting plate 7. The screw 20 then causes the positioning sleeve 19 to move and reset, so that the inner wall of the positioning sleeve 19 again limits the outer wall of the positioning wheel 29, preventing the positioning wheel 29 and the positioning block 16 from sliding outward. The positioning wheel 29, in conjunction with the cylindrical block 18, limits the control sleeve 15, preventing accidental rotation and ensuring the structural stability after clamping, thus ensuring stable clamping.

[0039] In summary, when using or operating the equipment: First, place the irregularly shaped metal parts to be welded on the placement table 2. Then, unlock the clamping components and simultaneously open the two cylinders 24. This causes the piston rods 25 connected to the output ends of the cylinders 24 to push the moving seat 3, which in turn drives the moving sleeve 4 and other components to slide inward along the slide rail 23. After clamping the metal parts, relock the clamping components, then close the cylinders 24. Next, open the lifting assembly 26, causing it to move the upper moving assembly 27 and the welding torch assembly... Adjust the height of assembly 28. Once the height is adjusted to the appropriate level, turn off the lifting assembly 26 and then turn on the moving assembly 27. Adjust the longitudinal position of the welding torch assembly 28. Once the position is adjusted to the appropriate level, turn off the moving assembly 27. Then, the clamped hardware parts can be welded using the welding torch assembly 28. You can also turn on the reduction motor 22 to drive the rotary table 1 connected to the output end to rotate. The rotary table 1 will then drive the placement platform 2 and the clamped hardware parts above to rotate, thereby adjusting the angle of the hardware parts. Once the angle is adjusted to the appropriate level, turn off the reduction motor 22.

[0040] When it is necessary to unlock the clamping component, first rotate the control sleeve 5 forward. The control sleeve 5 will drive the driving wheel 6 on one side to rotate forward. Then, the driving wheel 6 will drive the driven wheel 9 meshing with it to rotate in the opposite direction. Then, the driven wheel 9 will drive the screw sleeve 8 to rotate in the opposite direction on the mounting plate 7. Then, the screw 20 will drive the positioning sleeve 19 to slide, so that the positioning sleeve 19 no longer limits the outer wall of the positioning wheel 29. Then, rotate the control sleeve 15 forward. The control sleeve 15 will drive the positioning rail 30 on one side to rotate forward. Then, the positioning rail 30 will drive the positioning block 16 to rotate forward through the positioning groove 31. Then, the positioning block 16 will drive the positioning wheel 29 on one side to move out from between the two cylindrical blocks 18, and the positioning wheel 29 will drive the positioning block 16 along... As the positioning rail 30 and positioning groove 31 slide outward, the positioning block 16 pulls the positioning spring outward. Simultaneously, because the inner wall of the control sleeve 15 and the outer wall of the linkage sleeve 14 are connected by threads, and because the linkage block 36 and linkage groove 35 limit the linkage sleeve 14, the linkage sleeve 14 will not rotate. Then, the linkage sleeve 14, through the cooperation of the linkage groove 35 and linkage block 36, drives the fastening block 12 to slide, causing the fastening block 12 to drive one side of the control plate 11 to slide along the inclined control groove 10. Then, the control plate 11 will drive the fastening block 12 to slide outward, causing the fastening block 12 to drive one side of the linkage plate to slide outward along the linkage groove 35. Then, the inner wall of the fastening block 12 no longer clamps the outer wall of the clamping rod 13. When the cylinder 24... When the piston rod 25 pushes the moving seat 3 to move, the moving seat 3 will drive the moving sleeve 4 and other components to move inward. Then, the clamping rod 13, which is in contact with the outer wall of the irregular hardware workpiece, will stop moving. Then, the clamping rod 13 will slide relative to the inner side of the linkage sleeve 14 and the fixed plate 32. Then, the moving sleeve 4 will drive the fixed plate 32 to move, so that the fixed plate 32 will drive the tension spring 34 to stretch. When one end of all the clamping rods 13 is in contact with the outer wall of the irregular hardware, the tension spring 34 will be stretched to different degrees. Then, the cylinder 24 will be closed. When it is necessary to lock the clamping components, the control sleeve 15 will be rotated in the opposite direction. The control sleeve 15 will drive the positioning block 16, the positioning wheel 29 and the movable spring through the cooperation of the positioning rail 30 and the positioning groove 31 on one side. 17 rotates in the opposite direction, and simultaneously, the linkage sleeve 14 slides in the opposite direction, causing the linkage sleeve 14 to push one side of the fastening block 12 to slide in the opposite direction. Then, the fastening block 12 will drive one side of the control plate 11 to slide in the opposite direction in the control groove 10. Due to the inclined opening of the control groove 10, the control plate 11 will then drive one side of the fastening block 12 to converge inward, causing the fastening block 12 to drive one side of the linkage block 36 to slide inward along the linkage groove 35. Then, the inner wall of the fastening block 12 will press against the outer wall of the clamping rod 13 again, so that the clamping rod 13 will not move. At this time, the positioning rail 30 will drive the positioning block 16 and the positioning wheel 29 to the position corresponding to the original two cylindrical blocks 18 through the positioning groove 31. Then, the movable spring 17 will reset and pull the positioning block 16.The positioning block 16 causes one side of the positioning wheel 29 to slide inward along the positioning rail 30 and positioning groove 31, allowing the positioning wheel 29 to re-engage between the two original cylindrical blocks 18. Then, the control sleeve 5 is rotated in the reverse direction, causing some of the drive wheels 6 to rotate in the reverse direction. The drive wheels 6 then drive the driven wheels 9 that mesh with them to rotate in the forward direction. The driven wheels 9 then drive the screw sleeve 8 to rotate in the forward direction on the mounting plate 7. The screw 20 then causes the positioning sleeve 19 to move and reset, so that the inner wall of the positioning sleeve 19 again limits the outer wall of the positioning wheel 29, preventing the positioning wheel 29 and the positioning block 16 from sliding outward. The positioning wheel 29, in conjunction with the cylindrical block 18, limits the control sleeve 15, preventing accidental rotation and ensuring the structural stability after clamping, thus ensuring stable clamping.
