Description

Technical Field

[0001] This utility model relates to the technical field of circumferential welding, specifically to a dual-station welding station. Background Technology

[0002] Dual-station circumferential welding is a highly efficient and automated welding process, primarily used for the continuous production of circular or annular workpieces, such as pipes, pressure vessels, storage tanks, and flanges. Its core design utilizes two alternating stations to simultaneously load and unload workpieces, significantly improving production efficiency. Specifically, while welding is being performed at station A, station B simultaneously clamps and centers a new workpiece. After welding is complete, a rotary table or slide exchanges positions between the two stations; station B then enters the welding state, while station A unloads and re-clamps the workpiece. This alternating operation eliminates the waiting time of traditional single-station welding, enabling continuous production. However, this welding mode can only handle welding a single seam; it is no longer suitable for double-seam welding. Utility Model Content

[0003] This invention proposes a dual-station welding station that can simultaneously meet the needs of single-seam or double-seam welding, enabling workpiece loading and unloading and welding to be carried out synchronously, thus significantly improving production efficiency.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A dual-station welding station includes a worktable with a fixed transmission track. The transmission track has a ring structure and is fitted with several support plates that are slidably connected to it along the track. Each support plate is fixed with a clamping mechanism, and the center of the transmission track has a drive block that is fixedly connected to each support plate. The drive block is rotatably connected to the worktable via a drive mechanism. Two welding mechanisms are also fixed on the worktable, and the welding guns of the welding mechanisms are located above the transmission track.

[0006] A further technical solution is that the clamping mechanism includes a chuck body fixed on a support plate, and a number of clamping claws are slidably fixed on the chuck body. The number of clamping claws are arranged in a circular array on the chuck body and driven by a driving mechanism to move back and forth along the outside of the chuck body toward the center of the chuck body.

[0007] A further technical solution is that the welding mechanism includes a support block fixed on the workbench, a mounting plate fixed on the top of the support block, an adjusting block slidably connected to the mounting plate, the adjusting block being driven by a driving mechanism to reciprocate toward the clamping mechanism on the mounting plate, a first slide rod fixed perpendicular to the adjusting block, a second slide rod vertically connected to the first slide rod via a locking block, a third slide rod vertically connected to the second slide rod via a locking block, the locking block being slidably connected to the first slide rod, the second slide rod, and the third slide rod, a connecting block fixed to the third slide rod, and a welding torch detachably connected to the connecting block.

[0008] A further technical solution is that the workbench also has a pressing mechanism, which includes a mounting frame fixed on the workbench. A lifting plate is slidably connected to the mounting frame. The lifting plate is driven to move up and down along the mounting frame by a driving mechanism. A vertically arranged connecting rod is fixed on the lifting plate, and a pressing block is fixed at the bottom end of the connecting rod.

[0009] A further technical solution includes a control system, wherein the signal input terminal of the control system is connected to the controller, and the control output terminal is connected to drive mechanism one, drive mechanism two, drive mechanism three, and drive mechanism four.

[0010] A further technical solution is that sliding holes are provided at the connection points of the locking block with the first slide rod, the second slide rod and the third slide rod, and a locking nut is provided on the side wall of the locking block, which can pass through the side wall of the locking block and enter the sliding hole.

[0011] The working principle and beneficial effects of this application are as follows:

[0012] 1. With two welding mechanisms at two workstations, when double-seam welding is required, the two welding torches are adjusted to the required position and height of the two weld seams respectively, and double-seam welding can be achieved without further adjustment of the welding torches.

[0013] 2. Simultaneously, the conveyor track first transports the first clamping mechanism, which has fixed the workpiece to be welded, to the first welding mechanism for the first weld seam. During the welding process, the remaining clamping mechanisms clamp and fix the workpiece in sequence. After the welding at the first welding mechanism is completed, the conveyor track transports the first clamping mechanism to the second welding mechanism for the second weld seam. The clamping mechanisms that are subsequently clamped are then transported to the first welding mechanism for the first weld seam. This cycle repeats, achieving double-seam welding while allowing the workpiece loading and unloading to be carried out simultaneously with the welding, thus realizing automated continuous production.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-6As shown, a dual-station welding station includes a worktable 100. A transmission track 1 is fixed on the worktable 100. The transmission track 1 has a ring structure, and several support plates 11 are slidably connected to it along the track. Each support plate 11 is fixed with a clamping mechanism 2. The center of the transmission track 1 has a driving block 12 fixedly connected to each support plate 11. The driving block 12 is rotatably connected to the worktable 100 through a driving mechanism 13. The driving mechanism 13 drives the driving block 12 to rotate, thereby causing the support plates 11 to move along the transmission track 1 and change the position of the clamping mechanism 2. Two sets of welding mechanisms 3 are also fixed on the worktable 100. The welding guns 30 of the welding mechanisms 3 are all located above the transmission track 1.

[0024] In this embodiment, the welding station has two welding mechanisms 3 at two workstations. When double-seam welding is required, the two welding torches 30 are adjusted to the required heights of the two weld seams, and no further adjustments to the welding torches 30 are needed to achieve double-seam welding. Simultaneously, the transfer track 1 transports the first clamping mechanism 2, which holds the workpiece to be welded, to the first welding mechanism 3 for the first weld seam. During welding, the remaining clamping mechanisms 2 sequentially clamp and fix the workpiece. After welding at the first welding mechanism 3 is completed, the transfer track 1 transports the first clamping mechanism 2 to the second welding mechanism 3 for the second weld seam. Subsequent clamping mechanisms 2 are then transported to the first welding mechanism 3 for the first weld seam, and this cycle repeats continuously. This achieves double-seam welding while simultaneously enabling workpiece loading and unloading and welding to proceed synchronously, realizing automated continuous production.

[0025] In this embodiment, the clamping mechanism 2 includes a chuck body 21 fixed on a support plate 11. Several clamping claws 22 are slidably fixed on the chuck body 21. These claws 22 are arranged in a circular array on the chuck body 21 and are driven by a driving mechanism 23 to reciprocate along the outer side of the chuck body 21 towards its center. Figure 4 As shown, one embodiment features a chuck body 21 with three locking claws 22. The drive mechanism 23 is configured with a large bevel gear and three small bevel gears. The three small bevel gears mesh with the large bevel gear. The back of the large bevel gear has a planar thread structure. The three locking claws 22 are mounted at equal angles on the planar thread. When a wrench is used to turn the small bevel gear, the large bevel gear rotates, and the planar thread on its back causes the three locking claws to simultaneously move closer to or retract from the center. Because the pitch of the planar rectangular thread is equal, the movement distance of the three locking claws 22 is equal, providing an automatic centering function.

[0026] like Figure 6As shown, one embodiment of the welding mechanism 3 in this application includes a support block 32 fixed on a workbench 100. A mounting plate 33 is fixed to the top of the support block 32. An adjusting block 34 is slidably connected to the mounting plate 33. The adjusting block 34 is driven by a driving mechanism 35 to reciprocate on the mounting plate 33 toward the clamping mechanism 2. A first slide rod 36 perpendicular to the adjusting block 34 is fixed to the adjusting block 34. A second slide rod 37 is vertically connected to the first slide rod 36 via a locking block 39. A third slide rod 38 is vertically connected to the second slide rod 37 via the locking block 39. The locking block 39 is slidably connected to the first slide rod 36, the second slide rod 37, and the third slide rod 38. A connecting block 31 is fixed to the third slide rod 38. A welding torch 30 is detachably connected to the connecting block 31.

[0027] The locking block 39 has sliding holes at the connection points with the first slide rod 36, the second slide rod 37, and the third slide rod 38. A locking nut 391 is inserted through the side wall of the locking block 39. The locking nut 391 can pass through the side wall of the locking block 39 and enter the sliding hole to lock the first slide rod 36, the second slide rod 37, and the third slide rod 38. Thus, the driving block 12, the first slide rod 36, the second slide rod 37, and the third slide rod 38 can all change positions to achieve three-dimensional adjustment of the welding torch 30.

[0028] like Figure 5 As shown, the workbench 100 also has a pressing mechanism 4. The pressing mechanism 4 includes a mounting frame 41 fixed on the workbench 100. A lifting plate 42 is slidably connected to the mounting frame 41. The lifting plate 42 is driven to move up and down along the mounting frame 41 by a driving mechanism 43. A vertically arranged connecting rod 44 is fixed on the lifting plate 42, and a pressing block 45 is fixed to the bottom end of the connecting rod 44. The function of the pressing mechanism 4 is to press on the workpiece and, together with the clamping mechanism 2, fix the workpiece more stably. In use, after the clamping mechanism 2 clamps the workpiece and moves it to the welding position matching the welding torch 30, the driving mechanism 43 drives the connecting rod 44 to descend, and the pressing block 45 presses on the workpiece to prevent the workpiece from shifting during welding. After welding is completed, the driving mechanism 43 drives the connecting rod 44 to rise again. At this time, the transmission track 1 carries the workpiece to the next station.

[0029] The entire welding station is controlled by a control system. The signal input of the control system is connected to the controller 5, and the control output is connected to drive mechanism 13, drive mechanism 23, drive mechanism 35 and drive mechanism 43. The controller 5 sets the specified parameters according to the type of workpiece and the welding position to realize the automated welding process.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
