Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding apparatus for ship ventilation pipes. Background Technology

[0002] During the welding process of ship ventilation pipes, ventilation pipe welding equipment is required. Currently, the ventilation pipe welding equipment on the market mainly consists of a welding structure and a fixing structure. In actual use, the fixing structure includes a clamping plate and a support. The clamping plate and the ventilation pipe are equipped with a rotating structure. The ventilation pipe can rotate on the clamping plate by means of the rotating structure, which facilitates the alignment of the welding ends of the two ventilation pipes and makes it easier to weld two unconnected ventilation pipes into one piece. However, while the aforementioned ventilation duct welding equipment does achieve good welding results for ventilation ducts that are not connected at both ends, it still has some shortcomings in practical use, such as: Existing ventilation duct welding equipment does not have a good ventilation duct transmission structure. When welding a part of the ventilation duct, it is necessary to weld other parts of the ventilation duct. At this time, it is necessary to move the welding part of the ventilation duct. The transmission structure used in ventilation duct welding parts on the market mainly consists of a transmission component that abuts against the ventilation duct. The transmission component abuts against the part of the ventilation duct away from the welding end. When the welding part of the ventilation duct needs to be rotated, the transmission component will drive one of the ventilation ducts to rotate, thereby adjusting the welding parts of the two unconnected ventilation ducts. Although the transmission structure of the aforementioned ventilation duct welding equipment can adjust the welding parts of two unconnected ventilation ducts, the transmission structure drives the rotation of one ventilation duct to the other, which will cause uneven force on the welding parts of the two ventilation ducts. This can easily lead to damage to the weld seams of the two ventilation ducts, thereby affecting the quality of the weld seams of the two ventilation ducts. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a ship ventilation pipe welding device that can solve the technical problem in the prior art where the transmission structure drives one ventilation pipe to rotate, resulting in uneven stress on the welding parts of the two ventilation pipes and damage to the weld seams of the two ventilation pipes.

[0004] The technical solutions provided by the embodiments of the present invention are as follows: An embodiment of the present invention provides a welding device for ship ventilation pipes, comprising: a welding robot, a first fixing member, a second fixing member, and a connecting plate. The first fixing member and the second fixing member have the same structure and are connected to the connecting plate. The welding robot is distributed on one side of the connecting plate. The second fixing component includes a mounting base, a pressing component, and a rotating roller; The mounting base is fixed to the connecting plate. A snap-fit ​​seat is snapped into the inner wall of the mounting base. Rollers are evenly distributed on the snap-fit ​​seat. Fixed lugs are rotatably attached to both ends of the rollers. The fixed lugs are fixed to the snap-fit ​​seat. The pressing member is detached from the mounting base. The first fixing member and the second fixing member are both connected to the duct body, and the duct body on the first fixing member and the duct body on the second fixing member abut against each other. The connecting plate is connected to a transmission structure, which includes a transmission motor, a push wheel, and a pusher. The fixed end of the transmission motor is fixed to the connecting plate, a drive rod is fixed on the push wheel, the drive rod is fixed to the drive end of the transmission motor, the push part is fixed relative to the push wheel, and the push part abuts against the duct body.

[0005] The pressing component includes a flipping component, a screw component, and a pressing block; The flipping component is installed on the mounting base. A screw sleeve is threaded onto the screw component. The screw sleeve and the flipping component are fixed together. A stop block is rotatably mounted on the lower end of the screw component. A bullseye wheel is fixed on the bottom surface of the stop block. A rotating head is fixed on the upper end of the screw component.

[0006] The mounting base on the first fixing member is connected to an electric slide rail. The fixed end of the electric slide rail is fixed to the connecting plate, and the end of the mounting base on the first fixing member that is away from the electric slide rail slides against the connecting plate.

[0007] The pushing part has extrusion blocks that are evenly spaced through it. The extrusion block is a block-shaped structure that is tilted on one side. The upper part of the extrusion block abuts against the air duct body. The side of the extrusion block that abuts against the air duct body is rough.

[0008] The lower part of the extrusion block abuts against a first support block and a second support block. The second support block is fixed to a push wheel. An abutting part is fixed on the first support block. The abutting part and the push part are fixedly connected.

[0009] The pushing part, the abutting part, and the pushing wheel form a hollow cavity structure. The pushing part and the abutting part are elastic, and the side of the abutting part facing away from the first support block is rough.

[0010] A dust exhaust pipe is distributed on the side away from the welding robot between the first and second fixing components. The dust exhaust pipe has a notch near the duct body. A rotating rod is rotatably mounted on the inner wall of the notch. Brush bristles are fixed on the rotating rod at equal intervals.

[0011] A first gear is fixed to one end of the rotating rod that passes through the dust exhaust pipe. A toothed belt is fitted onto the first gear, and a second gear is connected to the toothed belt. The second gear is fixed to the drive rod.

[0012] A rod is fixed to the mounting seat on the first fixing member, a tube is sleeved on the rod, and the tube is fixed to the mounting seat on the second fixing member.

[0013] Support frames are fixed on both sides of the connecting plate. The support frames abut against the air duct body, and the abutment part of the support frames and the air duct body is provided with a rotating wheel.

[0014] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this invention, when the two duct bodies abut against each other, the push wheel abuts against the part where the two duct bodies abut against each other. The push wheel is a columnar structure with a concave center. The concave center of the push wheel will not contact the welding surface of the duct body. This allows the output shaft of the drive motor to drive the push wheel through the drive rod during the welding of the two duct bodies, thereby providing a pushing force to the two duct bodies and adjusting the welding part of the two duct bodies to ensure the quality of the duct body welding.

[0015] In this invention, when the push wheel drives the duct body to rotate on the first and second fixing parts through the push part, the second gear drives the first gear to rotate through the toothed belt. At the same time, the first gear drives the brush to clean the welding slag on the weld seam of the duct body through the rotating rod.

[0016] In this invention, the exhaust end of the dust extraction pipe is connected to the external dust extraction structure. When the external dust extraction structure is working, the receiving end of the external dust extraction structure will draw air from the inside of the dust extraction pipe. At this time, the inside of the dust extraction pipe is in a negative pressure state. This allows the external air to enter the inside of the dust extraction pipe through the opening, and the external air blows the welding slag on the brush bristles to be transported to the receiving end of the external dust extraction structure, so as to realize the external dust extraction structure to centrally clean the welding slag separated from the brush bristles.

[0028] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions 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, not all embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0031] Reference manual attached Figures 1 to 8 An embodiment of the present invention provides a welding device for ship ventilation pipes, comprising: a welding robot 1, a first fixing member 3, a second fixing member 8, and a connecting plate 7. The first fixing member 3 and the second fixing member 8 have the same structure and are connected to the connecting plate 7. The welding robot 1 is distributed on one side of the connecting plate 7.

[0032] The second fixing member 8 includes a mounting base 24, a pressing member, and a rotating roller 22.

[0033] Mounting base 24 is fixed on connecting plate 7. A snap-fit ​​seat 21 is snapped into the inner wall of mounting base 24. Rollers 22 are evenly distributed on snap-fit ​​seat 21. Fixed lugs 23 are rotated at both ends of rollers 22. Fixed lugs 23 are fixed to snap-fit ​​seat 21. Pressing parts are installed and removed from mounting base 24.

[0034] The air duct body 5 is inserted into both the first fixing member 3 and the second fixing member 8, and the air duct body 5 on the first fixing member 3 and the air duct body 5 on the second fixing member 8 abut against each other.

[0035] A transmission structure is connected to the connecting plate 7. The transmission structure includes a transmission motor 6, a push wheel 61, and a pusher 64.

[0036] The fixed end of the drive motor 6 is fixed to the connecting plate 7. The drive rod 63 is fixed on the push wheel 61. The drive rod 63 is fixed to the drive end of the drive motor 6. The push part 64 is fixed relative to the push wheel 61. The push part 64 abuts against the duct body 5. The pressing parts include the flipping part 2, the screw part 27 and the abutting block 29.

[0037] The flip-up part 2 is installed on the mounting base 24. The screw part 27 is threaded with a screw sleeve 26. The screw sleeve 26 and the flip-up part 2 are fixed. The lower end of the screw part 27 has a rotating abutment block 29. The bottom surface of the abutment block 29 is fixed with a bullseye wheel 28. The upper end of the screw part 27 is fixed with a rotating head 25.

[0038] Specifically, in actual use, the duct body 5 on the first fixing member 3 and the duct body 5 on the second fixing member 8 abut together. Then, the operator rotates the rotating head 25 in the opposite direction. The rotating head 25 can drive the screw member 27 to rotate, thereby realizing the downward movement of the abutting block 29. When the abutting block 29 abuts against the duct body 5, the abutting block 29 can press against the duct body 5 through the bullseye wheel 28, thereby fixing the duct body 5 on the rotating roller 22, which is convenient for the welding robot 1 to weld the contact parts of the two duct bodies 5.

[0039] When the duct body 5 is fixed on the rotating roller 22, since the rotating roller 22 rotates on the fixed lug 23, the rotating roller 22 rotates on the fixed lug 23 when the duct body 5 rotates around its own axis, which reduces the friction between the duct body 5 and the rotating roller 22 and facilitates the relative position adjustment of the two duct bodies 5.

[0040] When the two duct bodies 5 abut against each other, the push wheel 61 can abut against the part where the two duct bodies 5 abut against each other. The push wheel 61 is a columnar structure with a concave center. The concave part of the push wheel 61 will not contact the welding surface of the duct body 5. This allows the output shaft of the drive motor 6 to drive the push wheel 61 to provide a pushing force to the two duct bodies 5 simultaneously through the drive rod 63 during welding, thereby adjusting the welding part of the two duct bodies 5 and ensuring the quality of the welding of the duct bodies 5.

[0041] In one possible implementation, the mounting base 24 on the first fixing member 3 is connected to the electric slide rail 73, the fixed end of the electric slide rail 73 is fixed to the connecting plate 7, and the mounting base 24 on the first fixing member 3 slides away from the end of the electric slide rail 73 and the connecting plate 7.

[0042] Specifically, when the rotating roller 22 needs to support the duct body 5, the working end of the electric slide rail 73 can drive the position adjustment of the mounting base 24, thereby enabling the rotating roller 22 on the first fixing member 3 to support different positions on the duct body 5, ensuring stable contact between the welded parts of the two duct bodies 5.

[0043] In one possible implementation, the pushing part 64 is provided with extrusion blocks 65 at equal intervals. The extrusion blocks 65 are block-shaped structures with one side inclined. The upper part of the extrusion blocks 65 abuts against the air duct body 5. The side of the extrusion blocks 65 that abuts against the air duct body 5 is rough.

[0044] Specifically, when the pushing part 64 drives the extrusion block 65 to abut against the outer wall of the duct body 5, the extrusion block 65 can be extruded by the duct body 5. At this time, the extrusion block 65 will extrude the first support block 66, thereby extruding the first support block 66 into the abutting part 68. At this time, the abutting part 68 will extrude the weld seam of the two duct body 5 welding parts, thereby extruding the weld slag on the weld seam. The weld slag after being extruded will loosen on the weld seam, making it easier for the weld slag on the weld seam to be separated in the future.

[0045] It should be noted that the end of the extrusion block 65 that abuts against the duct body 5 has a rough surface. The advantage of this design is that it allows for friction between the extrusion block 65 and the duct body 5, making it easier for the extrusion block 65 to push the duct body 5.

[0046] Please refer to the attached diagram in the instruction manual. Figure 1 Since the transmission structure is distributed on the side of the connecting plate 7 away from the welding robot 1, the duct body 5 will be exposed to the air before the abutting part 68 squeezes the weld of the duct body 5. This allows the weld of the duct body 5 to be cooled in the external environment. In order to achieve rapid cooling of the weld on the duct body 5 and brittleness of the weld slag, the operator can set an external cooling structure on the connecting plate 7. The external cooling structure can rapidly cool the weld on the duct body 5. When the weld cools, the weld slag on the weld will brittle. At this time, when the abutting part 68 squeezes the weld slag on the weld, the squeezed weld slag will loosen on the weld, which is convenient for subsequent processing.

[0047] In one possible implementation, the lower part of the compression block 65 abuts against a first support block 66 and a second support block 67. The second support block 67 is fixed to the push wheel 61. An abutment part 68 is fixed on the first support block 66. The abutment part 68 is fixedly connected to the push part 64.

[0048] Specifically, when the extrusion block 65 and the pushing part 64 abut against the two sides of the welding part of the two air duct bodies 5, the abutting part 68 extrudes the welding slag on the weld. At this time, there will be friction between the abutting part 68 and the weld of the air duct body 5, which can enable the abutting part 68 to cooperate with the pushing part 64 to rotate the welding part of the two air duct bodies 5, thereby enabling the welding robot 1 to weld different parts of the air duct body 5.

[0049] In one possible implementation, the pushing part 64, the abutting part 68, and the pushing wheel 61 form a hollow cavity structure. The pushing part 64 and the abutting part 68 are elastic, so that after the extrusion block 65 extrudes the first support block 66, the pushing part 64 and the abutting part 68 can drive the extrusion block 65 to reset by their own restoring force. The side of the abutting part 68 that is away from the first support block 66 is rough.

[0050] In one possible implementation, a dust exhaust pipe 4 is distributed between the first fixing member 3 and the second fixing member 8 on the side away from the welding robot 1. A notch 42 is opened in the part of the dust exhaust pipe 4 near the air duct body 5. A rotating rod 43 is rotatably mounted on the inner wall of the notch 42. Brush bristles 41 are fixed on the rotating rod 43 at equal intervals.

[0051] A first gear 44 is fixed at one end of the rotating rod 43 that passes through the dust exhaust pipe 4. A toothed belt 45 is sleeved on the first gear 44. A second gear 62 is connected to the toothed belt 45. The second gear 62 is fixed on the drive rod 63.

[0052] Specifically, when the push wheel 61 drives the duct body 5 to rotate on the first fixing member 3 and the second fixing member 8 through the push part 64, the second gear 62 will drive the first gear 44 to rotate through the toothed belt 45. At the same time, the first gear 44 drives the brush 41 to clean the welding slag on the weld of the duct body 5 through the rotating rod 43.

[0053] The exhaust end of the dust pipe 4 is connected to the external dust collection structure. When the external dust collection structure is working, the receiving end of the external dust collection structure will draw air from the inside of the dust pipe 4. At this time, the inside of the dust pipe 4 is in a negative pressure state. This allows the external air to enter the inside of the dust pipe 4 through the notch 42, and the external air blows the welding slag on the bristles 41 to be transported to the receiving end of the external dust collection structure, so as to realize the external dust collection structure to centrally clean the welding slag separated from the bristles 41.

[0054] In one possible implementation, a rod 71 is fixed to a mounting seat 24 on the first fixing member 3, a rod sleeve 72 is sleeved on the rod 71, and the rod sleeve 72 is fixed to the mounting seat 24 on the second fixing member 8.

[0055] In one possible implementation, support frames 9 are fixed on both sides of the connecting plate 7. The support frames 9 abut against the duct body 5. A rotating wheel is provided at the abutment part of the support frame 9 and the duct body 5. The support frame 9 can support the duct body 5 through the rotating wheel, so that the duct body 5 can be stably fixed on the first fixing member 3 and the second fixing member 8.

[0056] Specifically, when the working end of the electric slide rail 73 moves the position of the first fixing member 3, the first fixing member 3 will move the insertion rod 71 inside the rod cylinder 72. At this time, the length of the insertion rod 71 will change. When the insertion rod 71 is used in conjunction with the rod cylinder 72, it can protect the welding parts of the two air duct bodies 5 and prevent external objects from contacting the welding parts of the air duct body 5 due to accidental circumstances.
