Description

Technical Field

[0001] This utility model belongs to the technical field of robotic welding workstations, specifically relating to a robotic welding workstation for tanks. Background Technology

[0002] When welding the circumferential weld seam of a tank, the robotic welding workstation places the assembled tank on the welding platform. Rollers support the tank and rotate it, while the welding torch remains stationary in a specific position. The circumferential weld seam is then welded as the tank rotates. Maintaining stable tank rotation is crucial for ensuring weld quality. During welding, weld beads and scale fall onto the rollers. Some of these fall off with the rollers, while others adhere. The uneven distribution of these adhered weld beads and scale causes instability in the tank's rotation, leading to misalignment between the welding torch and the weld seam, resulting in a lower weld quality. Furthermore, a large amount of weld beads and scale adhere to the weld surface and its vicinity during tank welding, which cannot be automatically removed and requires manual removal after welding, a time-consuming and labor-intensive process.

[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a tank robot welding workstation.

DETAILED DESCRIPTION

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figure 1 As shown, a tank robot welding workstation according to one embodiment of the present invention includes a platform body 1, and multiple fixed brackets 2 are bolted to the platform body 1. The fixed brackets 2 are rotatably connected to rollers 3, and the fixed brackets 2 support the rotation of the rollers 3. During welding, the welding torch is stationary, and the rotation of the rollers 3 drives the tank on them to rotate, so as to realize the relative movement between the welding torch and the circumferential weld seam and complete the welding of the circumferential weld seam.

[0029] A first cleaning component 4 is welded to one end face of the fixed bracket 2. The position of the first cleaning component 4 matches that of the roller 3. One end face of the first cleaning component 4 is in contact with the surface of the roller 3. When the roller 3 rotates and passes through the first cleaning component 4, the weld beads and oxide scale on the surface of the roller 3 are scraped off by the first cleaning component 4. After passing through the first cleaning component 4, the surface of the roller 3 returns to a clean state.

[0030] A second cleaning component 5 is fixedly connected to one end face of the platform body 1. The position of the second cleaning component 5 matches the position of the circumferential weld of the tank body. The second cleaning component 5 is in close contact with the circumferential weld of the tank body. When the tank body rotates, the circumferential weld rubs against one end face of the second cleaning component 5. Since the second cleaning component 5 has a certain width, it can encompass the circumferential weld and a certain width area on both sides. After the circumferential weld passes through the second cleaning component 5, the oxide scale on the circumferential weld and the weld beads on both sides will be brushed off by the second cleaning component 5.

[0031] like Figure 3 As shown, the first cleaning component 4 includes a pair of support frames 401. The pair of support frames 401 are located on both sides of the roller 3 and welded to the opposite end faces of the fixed bracket 2. Both support frames 401 are connected to the same scraper 403. One end face of the scraper 403 is an arc-shaped surface that matches the roller 3 and fits tightly with the roller 3. When there are weld beads and oxide scale on the surface of the roller 3, the weld beads and oxide scale on the roller 3 will be scraped off by the scraper 403 because the scraper 403 fits tightly.

[0032] Each pair of support frames 401 has a first shaft hole 402, and the scraper 403 has a second shaft hole 404 that matches the first shaft hole 402. A pin 405 is inserted into each pair of first shaft holes 402, passing through the first shaft hole 402 and the second shaft hole 404, thereby fixing the scraper 403 to the support frame 401. When the scraper 403 is worn and affects its use, it can be easily replaced. One end of the pin 405 is chamfered, so that the pin 405 can be easily inserted into the first shaft hole 402 and the second shaft hole 404.

[0033] Multiple first dust collection boxes 6 are placed on the platform body 1. The multiple first dust collection boxes 6 are located below the first cleaning component 4. The weld beads and oxide scale removed by the first cleaning component 4 fall into the first dust collection box 6. A pair of handles 7 are welded to the opposite end faces of the first dust collection box 6. When the weld beads in the first dust collection box 6 accumulate to a certain amount, the first dust collection box 6 can be moved by the handles 7 to remove the debris accumulated in the first dust collection box 6.

[0034] like Figure 4 As shown, a T-shaped groove 8 is provided in the middle of one end face of the platform body 1. A pair of second bolts 514 are slidably connected in the groove wall of the T-shaped groove 8. The second bolts 514 slide in the groove wall of the T-shaped groove 8. The second cleaning assembly 5 includes a support box 511. A pair of third shaft holes 512 matching the second bolts 514 are provided in one end face of the support box 511. The screw of the second bolt 514 passes through the third shaft hole 512. The second bolt 514 is threadedly connected to a first nut 513. Tightening the first nut 513 can compress the support box 511 to make it fit tightly against the surface of the platform body 1, thereby fixing the second cleaning assembly 5 on the platform body 1. When it is necessary to adjust the position of the second cleaning assembly 5 to match the circumferential weld, loosening the first nut 513 can allow the second cleaning assembly 5 to slide along the T-shaped groove 8.

[0035] The support box 511 is slidably connected with a sliding block 509, which can slide inside the support box 511. When sliding, the sliding block 509 is mostly located inside the support box 511, and the support box 511 can well limit the movement range of the sliding block 509, so that the sliding block 509 can only slide up and down without tilting. A plurality of first limiting grooves 515 are formed in one side end face of the support box 511, and a plurality of second limiting grooves 516 matched with the first limiting grooves 515 are formed in one side end face of the sliding block 509. The spring 510 is placed in the groove wall of the first limiting groove 515, and the spring 510 extends into the side wall of the second limiting groove 516. The upper and lower ends of the spring 510 are respectively clamped in the first limiting groove 515 and the second limiting groove 516, so as to keep the position of the spring stable. The spring 510 can pop up the sliding block 509 to a certain height, so that the second cleaning assembly 5 can be closely attached to the girth weld. Since the spring 510 has a certain expansion space, it can adapt to tank bodies of different diameters and can keep the close degree of the second cleaning assembly 5 attached to the tank body.

[0036] A second dust collecting box 504 is inserted into the top end face of the sliding block 509, and a steel wire brush 501 is threadedly connected to the top end face of the second dust collecting box 504. The steel wire brush 501 is matched with the position of the girth weld of the tank body, and can cover the weld itself and a certain space on both sides thereof. Since the steel wire brush 501 is flexible, it can be closely attached to the weld and the base material at the same time, so that the steel wire brush 501 sweeps off the weld beads and the oxide skin, and the second dust collecting box 504 can contain these swept-off weld beads and oxide skin.

[0037] First threaded holes 502 are formed in opposite ends of the steel wire brush 501, and second threaded holes 505 matched with the first threaded holes 502 are formed in one side end face of the second dust collecting box 504. First bolts 503 are threadedly connected to the first threaded holes 502 and the second threaded holes 505, and the first bolts 503 fix the steel wire brush 501 on the second dust collecting box 504. When the steel wire brush 501 needs to be replaced, the first bolts 503 can be removed for convenient replacement.

[0038] A T-shaped limiting block 506 in the shape of an inverted T is integrally formed in the bottom end face of the second dust collecting box 504, and a T-shaped limiting groove 507 matched with the T-shaped limiting block 506 is formed in the top end face of the sliding block 509. The T-shaped limiting block 506 is slid into the T-shaped limiting groove 507 from the side, so as to realize the insertion of the second dust collecting box 504 and the sliding block 509. When the weld beads and the oxide skin in the second dust collecting box 504 accumulate to a certain amount, the second dust collecting box 504 is slid off the sliding block 509, and then the second dust collecting box 504 can be removed to dispose of the weld beads and the oxide skin therein.

[0039] The outer side end surface of the sliding block 509 is welded with a skirt-shaped dust plate 508, the projection area of the dust plate 508 is greater than the area of the top end surface of the supporting box 511, so that when the sliding block 509 slides in the supporting box 511, the dust plate 508 can cover the joint between the sliding block 509 and the supporting box 511, preventing sundries from falling into the joint and affecting the up-down sliding of the sliding block 509.

[0040] In use, as shown in Figure 1 The tank body is placed on the roller 3, the roller 3 supports and rotates the tank body, the position of the welding gun and the weld is adjusted, the welding gun is fixed and the tank body rotates, so that the welding of the weld of the tank body is realized. During the welding process, the welding spatters and the oxide skin fall to the roller 3, part of the welding spatters and the oxide skin slide off with the rotation of the roller 3, and the other part of the welding spatters and the oxide skin adheres to the roller 3 and cannot slide off naturally. When the adhered welding spatters and the oxide skin pass through the scraper 403, the scraper 403 is attached to the surface of the roller 3, the roller 3 rotates and passes through the scraper 403, and the scraper 403 can shovel off the adhered welding spatters and the oxide skin on the roller 3. The shovelled off welding spatters and the oxide skin fall into the first dust collecting box 6, and are concentrated and disposed after accumulating to a certain amount. At the same time, the second cleaning assembly 5 is slid and adjusted to a proper position, so that the circumferential weld is located at the middle part of the steel wire brush 501. Due to the elastic support of the spring 510 and the deformation of the bristles of the steel wire brush 501, the steel wire brush 501 is closely attached to the weld and the base material on both sides of the weld. When the tank body rotates, the welding spatters and the oxide skin can be brushed off, and the brushed off welding spatters and the oxide skin fall into the second dust collecting box 504. After accumulating to a certain amount, the second dust collecting box 504 can be easily cleaned.
