Description

Technical Field

[0001] This invention relates to welding, and more particularly to a welding apparatus. Background Technology

[0002] like Figure 7 As shown, a T-shaped welding plate includes a main board and side plates symmetrically arranged on both sides of the main board. A vertical plate is fixedly arranged on the top of the main board, and the side plates are fixed to the main board by welding.

[0003] Existing welding technologies are divided into manual welding and automated welding. Manual welding offers greater freedom but carries higher risks and relies heavily on the welder's experience. It is suitable for relatively complex and small-batch workpieces. Automated welding, on the other hand, ensures welding quality through high-precision moving devices, but requires customized programs. Therefore, it is suitable for large-batch and relatively simple parts.

[0004] Currently, Chinese patent CN209349740U discloses a three-axis orthogonal intersection welding machine, which includes a worktable, a slide rail, a Y-axis moving frame, a turntable, a gantry-type X-axis moving frame, a Z-axis moving frame, and a welding mechanism. The turntable drives the workpiece to rotate so that the welding point is better aligned with the welding mechanism.

[0005] The aforementioned patent still has shortcomings. When the height of the upright plate is higher than the maximum height of the Z-axis moving frame, the welding mechanism can only be set on one side of the upright plate and cannot be moved to the other side to weld the main plate and side plate. Usually, the workpiece is turned around by a turntable or other turning equipment before welding. However, the main plate and side plate mentioned above are quite long, and turning them around by a turntable requires a large space and a large turntable, which makes the equipment less compact. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a welding device that has the advantage of being compact.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is: a welding device, comprising: A transport device used to drive the motherboard and side panel to move along the X-axis; The welding device includes a first drive assembly, a second drive assembly, and a welding head. The first drive assembly and the second drive assembly are symmetrically arranged on both sides of the transport device. The welding head is detachably connected to both the first drive assembly and the second drive assembly. The first drive assembly and the second drive assembly drive the welding head to move in the Y-axis and Z-axis directions. The output ends of the first drive assembly and the second drive assembly are each provided with a locking component, which is used to fix the welding head.

[0008] Using the above-mentioned technical means, the parts to be welded are transported to the welding device by a transport device, and then welded by a welding head. The welding head is detachably connected to the first drive component and the second drive component. After welding is completed on one side of the first drive component, the welding head is automatically placed to the output end of the second drive component and locked by a locking component, so that the position of the welding head is automatically replaced to the side of the second drive component. This allows the welding device to have lower height requirements while enabling welding on both sides of the welding plate, increasing the compactness of the equipment. At the same time, the replacement of the welding head reduces the manufacturing cost of the equipment.

[0009] Preferably, the locking component includes a locking block, and an installation block is fixedly disposed on the outer side of the welding head. The installation block has installation holes on both sides, and a locking groove is provided on the side of the locking block. A protrusion is slidably disposed in the locking groove, and a groove is provided on the inner side wall of the installation hole. The welding device also includes a drive source one, which drives the protrusion to protrude from the locking groove and engage with the groove.

[0010] By using the above-mentioned technical means, the protrusion is inserted into the groove by the drive source one, and the locking block is fixed in the mounting hole, so as to realize the disassembly and installation of the welding head with the first drive component and the second drive component, thereby allowing the first drive component and the second drive component to alternately fix the welding head.

[0011] Preferably, the driving source includes an air pump, and an air passage is provided inside the welding head. One end of the air passage is connected to the locking groove, and the other end is connected to the air pump.

[0012] By using the above-mentioned technical means, the gas pressure in the air passage is controlled by an air pump, and the gas pressure causes the protrusion to retract into or protrude from the locking groove, thereby achieving the fixing and disassembly of the welding head. Controlling the movement of the protrusion by gas makes the processing of the locking block simpler, reduces the processing difficulty, and reduces the number of mechanical parts inside the locking block, thus increasing stability.

[0013] Preferably, the transport device includes a transport section, a feeding section, a processing section, a discharging section, and a turning section. The welding device is disposed on both sides of the processing section, the feeding section is disposed on the upper side of the processing section, the turning section is disposed on the side end of the processing section, the discharging section is disposed on the upper end of the turning section, and the transport section moves between the feeding section, the processing section, and the discharging section.

[0014] Through the above-mentioned technical means, the feeding and discharging parts enable the welding plates to be automatically fed and unloaded, and the flipping part enables the welding plates to be automatically flipped and welded, thereby increasing the automation level of the equipment.

[0015] Preferably, the transport section includes a second drive source and a pair of conveyor belts, with a slot between the conveyor belts for the upright plate to pass through. Positioning blocks are symmetrically arranged at both ends of the conveyor belts. The second drive source drives the conveyor belts to move up and down. The feeding section, processing section and discharging section are all composed of a pair of conveyor belts, with a slot in the middle of the conveyor belts for the upright plate to pass through. Positioning blocks are symmetrically arranged at both ends of the conveyor belts.

[0016] Through the above technical means, after the welding plate in the empty trough is reversed, interference between the top plate and conveyor belt 1 and conveyor belt 2 is prevented. The positioning block increases the movement accuracy of the welding plate during transportation and prevents the welding plate from shifting.

[0017] Preferably, the reversing part includes a bogie and a drive source three disposed at the tail of the bogie. The drive source three drives the bogie to rotate. A pair of abutments are detachably disposed at the upper end of the bogie. A slot two is formed in the middle of the abutments. After the welding plate is reversed, the abutments abut against the welding plate, and the upright plate passes through the slot two. A push cylinder is also disposed at the tail of the bogie. The push cylinder pushes the welding plate to move.

[0018] Through the above-mentioned technical means, the welding plate is pushed into the bogie, and the rotation of the bogie is controlled by the drive source three to realize the reversal of the welding plate. The bottom block is detachably connected to the bogie, making the bogie suitable for welding plates of more sizes. After the welding plate is rotated by the push cylinder, the welding plate can be automatically pushed out of the bogie, increasing the degree of automation.

[0019] Preferably, the bogie is further provided with a support frame on the side away from the drive source. The support frame is rotatably connected to the bogie. The bogie is provided with an annular block. The annular block is provided with a positioning hook on its side end. The support frame is provided with a positioning groove. The positioning hook is inserted into the positioning groove. The support frame is also provided with a cover plate on its side end. The cover plate is detachably connected to the support frame.

[0020] By using the above-mentioned technical means, the other end of the bogie is fixed by the support frame, which reduces the impact of gravity on the third drive source and increases the service life of the third drive source. At the same time, it makes both sides of the bogie stable and increases the rotation accuracy of the bogie. The cooperation between the positioning groove and the positioning hook makes the cooperation accuracy between the bogie and the support frame even higher. Attached Figure Description

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0024] A welding device includes a conveying device 1 and a welding device 2. The conveying device 1 consists of several conveyor belts, with a rotating shaft 3 located in the middle of each conveyor belt. The rotating shaft 3 is controlled by a motor to rotate. The conveying device 1 includes a conveying section 4, a feeding section 5, a processing section 6, a discharging section 7, and a tilting section 8. The welding device 2 is located on both sides of the processing section 6. The feeding section 5 is located on the upper side of the processing section 6, the tilting section is located at the side end of the processing section 6, and the discharging section 7 is located at the upper end of the tilting section. The conveying section 4 moves between the feeding section 5, the processing section 6, and the discharging section 7. Part 4 includes a second drive source 9 and a pair of conveyor belts 10. The second drive source 9 includes a vertical cylinder, which is arranged on both sides of the first conveyor belt 10 to drive the first conveyor belt 10 to move between the processing part 6 and the feeding part 5 and the discharging part 7, thereby transporting the welding plates to be processed and processed. The feeding part 5, the processing part 6 and the discharging part 7 are all composed of a pair of second conveyor belts 11. A slot 12 is left between the first conveyor belt 10 and the second conveyor belt 11 for the vertical plate 92 to pass through. Positioning blocks 13 are symmetrically arranged on both sides of the first conveyor belt 10 and the second conveyor belt 11.

[0025] The empty slot 12 prevents interference between the top plate and the first conveyor belt 10 and the second conveyor belt 11 after the welding plate is reversed. The positioning block 13 increases the moving accuracy of the welding plate during transportation and prevents the welding plate from shifting.

[0026] The reversing section includes a bogie 14 and a drive source 3 15 located at the tail of the bogie 14. The drive source 3 15 includes a steering motor and drives the bogie 14 to rotate. A pair of abutments 16 are detachably provided on the upper end of the bogie 14. A slot 2 17 is formed in the middle of the abutments 16. When the welding plate needs to be reversed, the welding plate is fed into the bogie 14 by the conveyor belt 10 and the bogie 14 is rotated by the drive source 3 15. After the welding plate is reversed, the abutments 16 abut against the welding plate. At this time, the upright plate 92 passes through the slot 2 17 and aligns with the slot 12. A push cylinder 18 is also provided at the tail of the bogie 14. The push cylinder 18 pushes the welding plate and pushes it back onto the conveyor belt 10.

[0027] A support frame 19 is also provided on the side of the bogie 14 away from the drive source 3 15. The bottom of the support frame 19 is provided with a support foot 20, and the bottom of the drive source 3 15 is provided with a base 21. The bogie 14 is fixed by the support foot and the base 21. The support frame 19 is rotatably connected to the bogie 14. An annular block 22 is fixedly provided on the bogie 14. A positioning hook 23 is provided on the side end of the annular block 22. A positioning groove 24 is provided on the support frame 19. The positioning hook 23 is inserted into the positioning groove 24. When the annular block 22 rotates, the positioning hook 23 slides circumferentially in the positioning groove 24. A cover plate 25 is also provided on the side end of the support frame 19. The cover plate 25 is detachably connected to the support frame 19 by screws. The cover plate 25 prevents the positioning hook 23 from falling out of the positioning groove 24. The other end of the bogie 14 is fixed by the support frame 19, which reduces the impact of gravity on the drive source 3 15 and increases the service life of the drive source 3 15. At the same time, it makes both sides of the bogie 14 stable and increases the rotation accuracy of the bogie 14.

[0028] The welding device 2 includes a first drive assembly 26, a second drive assembly 27, and a welding head 28. The first drive assembly 26 and the second drive assembly 27 are symmetrically arranged on both sides of the conveyor belt 11 of the processing section 6. The welding head 28 is detachably connected to both the first drive assembly 26 and the second drive assembly 27. Both the first drive assembly 26 and the second drive assembly 27 are two-axis drive devices that drive the welding head 28 to move in the Y-axis and Z-axis directions. The output ends of both the first drive assembly 26 and the second drive assembly 27 are provided with locking components 29. When welding is completed on one side of the first drive assembly 26, the welding head 28 is automatically placed on the output end of the second drive assembly 27 and locked by the locking components 29, so that the position of the welding head 28 is automatically replaced on the side of the second drive assembly 27. This allows the welding device 2 to achieve welding on both sides of the welding plate while having lower height requirements, increasing the compactness of the equipment. At the same time, the replacement of the welding head 28 reduces the manufacturing cost of the equipment.

[0029] Locking assembly 29 includes a locking block 30. A mounting block 31 is fixedly mounted on the outer side of the welding head 28. Mounting holes 32 are provided on both sides of the mounting block 31. The locking block 30 is frustoconical in shape, with a connecting cylinder 33 at its front end. The connecting cylinder 33 is fixed to the locking block 30 by screws. A locking groove 34 is provided between the locking block 30 and the connecting cylinder 33. A protrusion 35 slides within the locking groove 34, and a flange is provided at the tail of the protrusion 35 to prevent it from falling off. The inner wall of the mounting hole 32... The welding device 2 includes a groove 37 and a drive source 1, which includes an air pump. The welding head 28 has an air passage 38 inside. One end of the air passage 38 is connected to the locking groove 34, and the other end is connected to the air pump. When the welding head 28 needs to be installed, the locking block 30 is inserted into the mounting hole 32 and tightened. Air is then pumped into the air passage 38 through the air pump to increase the pressure of the air passage 38 and make the protrusion 35 engage in the groove 37. When the welding head 28 needs to be disassembled, the pressure in the air passage 38 is reduced by the air pump.

[0030] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
