Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and specifically relates to a welding device. Background Technology

[0002] During circumferential welding, the welding torch needs to continuously rotate around the workpiece, causing the robot to rotate the torch. This can easily lead to the welding torch's wiring and the wire feeding wiring twisting together, resulting in entanglement that may not automatically separate after the robot resets and rotates, hindering continuous welding of circumferential welds. Utility Model Content

[0003] In view of the above problems, this application provides a welding device that can reduce the risk of the welding torch circuit and the wire feed line getting tangled together, which is beneficial for continuous welding of circumferential welds.

[0004] This application provides a welding apparatus for welding continuous circumferential welds, comprising a six-axis robot, a first mounting plate, a wire drawer, a first wire feeding tube, a welding torch, and a wiring conduit. The six-axis robot has an execution end. The middle portion of the first mounting plate is mounted on the execution end. The first mounting plate extends along a first direction and has a first end and a second end disposed opposite to each other. The first direction is perpendicular to the axial direction of the execution end. The wire drawer is connected to the first mounting plate and is located near the first end. The first wire feeding tube is connected to the wire drawer and is used to supply welding wire to the wire drawer. The welding torch is connected to the first mounting plate and is located near the second end. The wire drawer is used to drive the welding wire closer to the welding torch. The wiring conduit is connected to the welding torch and is used to accommodate the wiring of the welding torch. The middle portion of the first wire feeding tube is fixed to the first end, and the middle portion of the wiring conduit is fixed to the second end.

[0005] In the above technical solution, by fixing both the first wire feeding tube and the wiring tube to the mounting plate, the first wire feeding tube and the wiring tube can rotate in the same direction when the mounting plate and the welding gun are driven to rotate by the execution end. At the same time, by setting the first wire feeding tube and the wiring tube at the first end and the second end respectively, a certain distance is maintained between the first wire feeding tube and the wiring tube. This facilitates the isolation of the first wire feeding tube and the wiring tube by the welding gun, thereby limiting the entanglement of the first wire feeding tube and the wiring tube during rotation. This reduces the risk that the first wire feeding tube and the wiring tube cannot be separated when the mounting plate is reset by the execution end due to entanglement.

[0006] In some embodiments, the welding apparatus further includes a first mounting plate and a first adjusting plate. One end of the first mounting plate is mounted on the first mounting plate, and the other end of the first mounting plate extends along the axial direction; the first adjusting plate is adjustablely disposed on the first mounting plate along the axial direction and also adjustablely disposed on the first mounting plate along the first direction, and the wire drawer is disposed on the first adjusting plate.

[0007] In the above technical solution, the first adjusting plate is configured to be adjustable along the first direction and along the axial direction on the first assembly plate. This facilitates the adjustment of the distance between the wire drawer and the first end in both the axial and first directions, thereby straightening the portion of the first wire feeding tube located between the first end and the wire drawer. On the one hand, this reduces the risk of the first wire feeding tube becoming entangled with the wiring tube due to an excessive portion of the first wire feeding tube between the first end and the wire drawer; on the other hand, it reduces the risk of uneven wire feeding speed caused by excessive bending of the first wire feeding tube leading to greater friction on the welding wire.

[0008] In some embodiments, the first assembly plate is provided with a first strip hole extending along the axial direction, and the first adjustment plate is provided with a second strip hole extending along the first direction; the welding device further includes a connector and a nut, one end of the connector passes through the first strip hole and the second strip hole in sequence and is threadedly engaged with the nut, and the other end of the connector is used to drive the first assembly plate to abut against the first adjustment plate.

[0009] In the above technical solution, the first assembly plate and the first adjustment plate are fixed by passing one end of the connector through the first strip hole and the second strip hole in sequence and engaging with the nut thread. The structure is simple and easy to implement.

[0010] In some embodiments, the first strip hole is a plurality of holes spaced apart along the axial direction, and the second strip hole is a plurality of holes spaced apart along the first direction; the first strip hole and the second strip hole have multiple overlapping portions, and there are multiple connectors and multiple nuts, with the multiple connectors and multiple nuts corresponding to the multiple overlapping portions.

[0011] In the above technical solution, by setting multiple connectors and multiple nuts corresponding to multiple overlapping parts, the mutual rotation between the first assembly plate and the first adjustment plate is restricted, thereby making the position adjustment of the wire drawer more reliable.

[0012] In some embodiments, the welding device further includes a first latch and a second latch. The first latch is disposed at the first end and is used to latch the first wire feeding tube; the second latch is disposed at the second end and is used to latch the line tube.

[0013] In the above technical solution, the first wire feeding tube is detachably connected to the first end by setting a first buckle, which facilitates the adjustment of the tension of the first wire feeding tube. The circuit tube is detachably connected to the second end by setting a second buckle, which facilitates the adjustment of the tension of the circuit tube. The structure is simple and easy to implement.

[0014] In some embodiments, the first buckle is adjustablely disposed on the first mounting plate along the second direction; and / or, the second buckle is adjustablely disposed on the first mounting plate along the second direction, wherein the first direction, the second direction, and the axial direction are perpendicular to each other.

[0015] In the above technical solution, the first buckle is adjustablely disposed on the first mounting plate along the second direction to facilitate further adjustment of the distance between the wire drawer and the portion of the first wire feeding tube fixed at the first end, thereby making it easier to straighten the portion of the first wire feeding tube located between the first end and the wire drawer; the second buckle is adjustablely disposed on the first mounting plate along the second direction to facilitate further adjustment of the distance between the welding torch and the portion of the wiring tube fixed at the second end, thereby making it easier to straighten the portion of the wiring tube located between the second end and the welding torch, and further reducing the risk of the first wire feeding tube and the wiring tube becoming entangled due to an excessive portion of the first wire feeding tube located between the first end and the wire drawer.

[0016] In some embodiments, the welding apparatus further includes a mounting bracket, one end of which is mounted on the middle of the first mounting plate and located on the side of the first mounting plate away from the execution end, and the welding torch is disposed at the other end of the first mounting bracket away from the first mounting plate.

[0017] In the above technical solution, one end of the mounting bracket is installed in the middle of the first mounting plate so as to isolate the first wire feeding tube and the wiring tube through the mounting bracket, thereby further restricting the winding of the first wire feeding tube and the wiring tube during rotation, and further reducing the risk that the first wire feeding tube and the wiring tube cannot be separated when the actuator drives the mounting plate to reset due to the winding of the first wire feeding tube and the wiring tube.

[0018] In some embodiments, the mounting bracket includes a support, a crash plate, and a second mounting plate. One end of the support is connected to the middle of the first mounting plate, and the other end of the support extends along an axial direction. One end of the crash plate is mounted on the other end of the support away from the first mounting plate. The second mounting plate includes a first segment, a second segment, and a third segment connected in sequence. The first segment is parallel to a second direction, the second segment is parallel to the axial direction, and the third segment is parallel to the first direction. The end of the first segment away from the second segment is connected to the other end of the crash plate away from the support. The welding torch is connected to the end of the third segment away from the second segment and close to the second end. The first direction, the second direction, and the axial direction are perpendicular to each other.

[0019] In the above technical solution, the second mounting plate is configured to include a first segment, a second segment, and a third segment, with the first segment parallel to the second direction, the second segment parallel to the axial direction, and the third segment parallel to the first direction. The end of the first segment away from the second segment is connected to the other end of the anti-collision plate away from the bracket, and the welding torch is connected to the end of the third segment away from the second segment and close to the second end. This ensures that there is a certain distance between the welding torch and the anti-collision plate in the axial direction, thereby providing space for the assembly of the wiring tube and the welding torch, and reducing the risk of interference between the anti-collision plate and other structures and the end connected to the wiring tube and the welding torch when the execution end shakes.

[0020] In some embodiments, the mounting bracket further includes a connector, the two ends of which are connected to the third segment and the welding torch, respectively, and the connector extends along the second direction; at least a portion of the orthographic projection of the anti-collision disc overlaps with the orthographic projection of the connector in a plane perpendicular to the axial direction; and the welding torch protrudes from the side of the anti-collision disc away from the second segment along the second direction.

[0021] In the above technical solution, the welding torch protrudes from the side of the anti-collision plate away from the second section along the second direction, thereby further providing space for the assembly of the circuit pipe and the welding torch, and further reducing the risk of interference between the anti-collision plate and other structures and the end connected to the circuit pipe and the welding torch when the execution end shakes.

[0022] In some embodiments, the welding apparatus further includes a second wire feed tube, one end of which is connected to the wire drawer and is used to receive the welding wire, and the other end of which is located on the side of the welding torch closer to the first end.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Reference Figures 1-2This application provides a welding apparatus 100 for welding continuous circumferential welds, including a six-axis robot (not shown in the figure), a first mounting plate 10, a wire drawer 20, a first wire feeding tube (not shown in the figure), a welding torch 30, and a wiring tube (not shown in the figure). The six-axis robot has an execution end. The middle part of the first mounting plate 10 is mounted on the execution end. The first mounting plate 10 extends along a first direction X and has a first end 11 and a second end 12 disposed opposite to each other. The first direction X is perpendicular to the axial direction Z of the execution end. The wire drawer 20 is connected to the first mounting plate 10 and is close to the first end 11. The first wire feeding tube is connected to the wire drawer 20 and is used to provide welding wire to the wire drawer 20. The welding torch 30 is connected to the first mounting plate 10 and is close to the second end 12. The wire drawer 20 is used to drive the welding wire closer to the welding torch 30. The wiring tube is connected to the welding torch 30 and is used to accommodate the wiring of the welding torch 30. The middle part of the first wire feeding tube is fixed to the first end 11, and the middle part of the wiring tube is fixed to the second end 12.

[0032] It should be noted that the wire drawing device 20, welding torch 30, and six-axis robot are existing technologies and will not be described in detail here.

[0033] In this technical solution, by fixing both the first wire feeding tube and the wiring tube to the mounting plate, the first wire feeding tube and the wiring tube can rotate in the same direction when the mounting plate and the welding torch 30 are rotated by the actuator. At the same time, by setting the first wire feeding tube and the wiring tube at the first end 11 and the second end 12 respectively, a certain distance is maintained between the first wire feeding tube and the wiring tube. This facilitates the isolation of the first wire feeding tube and the wiring tube by the welding torch 30, thereby limiting the entanglement of the first wire feeding tube and the wiring tube during rotation. This reduces the risk that the first wire feeding tube and the wiring tube cannot be separated when the actuator drives the mounting plate to reset due to entanglement.

[0034] According to some embodiments of this application, the welding apparatus 100 further includes a first mounting plate 21 and a first adjusting plate 22. One end of the first mounting plate 21 is mounted on the first mounting plate 10, and the other end of the first mounting plate 21 extends along the axial direction Z; the first adjusting plate 22 is adjustablely disposed on the first mounting plate 21 along the axial direction Z, and is also adjustablely disposed on the first mounting plate 21 along the first direction X, and the wire drawer 20 is disposed on the first adjusting plate 22.

[0035] In this technical solution, the first adjusting plate 22 is configured to be adjustable along the first direction X and along the axial direction Z on the first assembly plate 21. This facilitates the adjustment of the distance between the wire drawer 20 and the first end 11 in the axial direction Z and the first direction X, so as to straighten the portion of the first wire feeding tube located between the first end 11 and the wire drawer 20. On the one hand, this reduces the risk of the first wire feeding tube getting tangled with the wiring tube due to an excessive portion of the first wire feeding tube located between the first end 11 and the wire drawer 20; on the other hand, when the wire drawer 20 drives the welding wire through the first wire feeding tube, it reduces the risk of uneven wire feeding speed caused by excessive bending of the first wire feeding tube and resulting in greater friction on the welding wire.

[0036] According to some embodiments of this application, the first assembly plate 21 is provided with a first strip hole 211 extending along the axial direction Z, and the first adjusting plate 22 is provided with a second strip hole 221 extending along the first direction X; the welding device 100 also includes a connector 44 and a nut, one end of the connector 44 passes through the first strip hole 211 and the second strip hole 221 in sequence and is threadedly engaged with the nut, and the other end of the connector 44 is used to drive the first assembly plate 21 to abut against the first adjusting plate 22.

[0037] For example, connector 44 can be a bolt.

[0038] In this technical solution, the first assembly plate 21 and the first adjusting plate 22 are fixed by passing one end of the connector 44 through the first strip hole 211 and the second strip hole 221 in sequence and engaging with the nut thread. The structure is simple and easy to implement.

[0039] According to some embodiments of this application, the first strip hole 211 is a plurality of holes spaced apart along the axial direction Z, and the second strip hole 221 is a plurality of holes spaced apart along the first direction X; the first strip hole 211 and the second strip hole 221 have multiple overlapping points, and there are multiple connectors 44 and nuts, with multiple connectors 44 and multiple nuts corresponding to the multiple overlapping points.

[0040] In this technical solution, by setting multiple connectors 44 and multiple nuts corresponding to multiple overlapping points, the mutual rotation between the first assembly plate 21 and the first adjustment plate 22 is restricted, thereby making the position adjustment of the wire drawer 20 more reliable.

[0041] According to some embodiments of this application, the welding device 100 further includes a first buckle 112 and a second buckle 122. The first buckle 112 is disposed at the first end 11 and is used to snap onto the first wire feeding tube; the second buckle 122 is disposed at the second end 12 and is used to snap onto the line tube.

[0042] In this technical solution, the first wire feeding tube is detachably connected to the first end 11 by setting the first buckle 112, which facilitates the adjustment of the tension of the first wire feeding tube. The circuit tube is detachably connected to the second end 12 by setting the second buckle 122, which facilitates the adjustment of the tension of the circuit tube. The structure is simple and easy to implement.

[0043] According to some embodiments of this application, a first buckle 112 is adjustablely disposed on a first mounting plate 10 along a second direction Y; and / or, a second buckle 122 is adjustablely disposed on a first mounting plate 10 along a second direction Y, wherein the first direction X, the second direction Y and the axial direction Z are perpendicular to each other.

[0044] In some embodiments, the first end 11 is provided with a first profile 111 extending along the second direction Y, and a first buckle 112 is adjustablely disposed in a groove of the first profile 111 along the second direction Y. The second end 12 is provided with a second profile 121 extending along the second direction Y, and a second buckle 122 is adjustablely disposed in a groove of the second profile 121 along the second direction Y. On the one hand, this allows the first buckle 112 and the second buckle 122 to be adjusted along the second direction Y; on the other hand, it improves the structural strength of the first end 11 and the second end 12.

[0045] In this technical solution, the first buckle 112 is adjustablely disposed on the first mounting plate 10 along the second direction Y, so as to further adjust the distance between the wire drawer 20 and the part of the first wire feeding tube fixed at the first end 11, thereby making it easier to straighten the part of the first wire feeding tube located between the first end 11 and the wire drawer 20; the second buckle 122 is adjustablely disposed on the first mounting plate 10 along the second direction Y, so as to further adjust the distance between the welding torch 30 and the part of the line tube fixed at the second end 12, thereby making it easier to straighten the part of the line tube located between the second end 12 and the welding torch 30, thereby further reducing the risk of the first wire feeding tube and the line tube becoming entangled due to the excessive part of the first wire feeding tube located between the first end 11 and the wire drawer 20.

[0046] According to some embodiments of this application, the welding apparatus 100 further includes a mounting bracket 40, one end of which is mounted on the middle of the first mounting plate 10 and located on the side of the first mounting plate 10 away from the execution end, and the welding torch 30 is disposed at the other end of the first mounting bracket 40 away from the first mounting plate 10.

[0047] In this technical solution, one end of the mounting bracket 40 is mounted in the middle of the first mounting plate 10 so as to isolate the first wire feeding tube and the wiring tube through the mounting bracket 40, thereby further restricting the winding of the first wire feeding tube and the wiring tube during rotation, and further reducing the risk that the first wire feeding tube and the wiring tube cannot be separated when the actuator drives the mounting plate to reset due to the winding of the first wire feeding tube and the wiring tube.

[0048] According to some embodiments of this application, the mounting bracket 40 includes a bracket 41, a crash plate 42, and a second mounting plate 43. One end of the bracket 41 is connected to the middle of the first mounting plate 10, and the other end of the bracket 41 extends along the axial direction Z. One end of the crash plate 42 is mounted on the other end of the bracket 41 away from the first mounting plate 10. The second mounting plate 43 includes a first segment 431, a second segment 432, and a third segment 433 connected in sequence. The first segment 431 is parallel to the second direction Y, the second segment 432 is parallel to the axial direction Z, and the third segment 433 is parallel to the first direction X. The end of the first segment 431 away from the second segment 432 is connected to the other end of the crash plate 42 away from the bracket 41. The welding torch 30 is connected to the end of the third segment 433 away from the second segment 432 and close to the second end 12. The first direction X, the second direction Y, and the axial direction Z are perpendicular to each other.

[0049] In this technical solution, the second mounting plate 43 is configured to include a first segment 431, a second segment 432, and a third segment 433, with the first segment 431 parallel to the second direction Y, the second segment 432 parallel to the axial direction Z, and the third segment 433 parallel to the first direction X. The end of the first segment 431 away from the second segment 432 is connected to the other end of the anti-collision plate 42 away from the bracket 41. The welding torch 30 is connected to the end of the third segment 433 away from the second segment 432 and close to the second end 12. This ensures that there is a certain distance between the welding torch 30 and the anti-collision plate 42 in the axial direction Z, thereby providing space for the assembly of the wiring tube and the welding torch 30, and reducing the risk of interference between the anti-collision plate 42 and other structures and the end connected to the wiring tube and the welding torch 30 when the execution end shakes.

[0050] According to some embodiments of this application, the mounting bracket 40 further includes a connector 44, the two ends of which are connected to the third segment 433 and the welding torch 30, respectively, and the connector 44 extends along the second direction Y; at least a portion of the orthographic projection of the anti-collision disc 42 overlaps with the orthographic projection of the connector 44 on a plane perpendicular to the axial direction Z; the welding torch 30 protrudes from the side of the anti-collision disc 42 away from the second segment 432 along the second direction Y.

[0051] In this technical solution, the welding torch 30 protrudes from the side of the anti-collision disc 42 away from the second section 432 along the second direction Y, thereby further providing assembly space for the circuit pipe and the welding torch 30, and further reducing the risk of interference between the anti-collision disc 42 and other structures and the end connected to the circuit pipe and the welding torch 30 when the execution end shakes.
