[0022] Reference Figure 1-4 The present invention proposes a welding device for easy adjustment of welding angle, comprising: a worktable 1, a platform 402, a clamping part, an annular slide 201, a slide block 203, a locking element, a welding torch 205, a support frame 301 mounted on the worktable 1, and a driving mechanism mounted on the support frame 301.

[0023] like Figure 1-2 As shown, the stage 402 is linearly slidably mounted on the table surface of the worktable 1. Specifically, a linear slide groove 401 is provided on the table surface of the worktable 1, and a slider is provided at the bottom of the stage 402, which is slidably fitted into the linear slide groove 401 so that the stage 402 can move along the linear slide groove 401 on the table surface of the worktable 1.

[0024] like Figure 3 As shown, the clamping component is mounted on the stage 402 for clamping the workpiece. Specifically, the clamping component includes a fixed plate 403, a clamping plate 405, a limiting rod 406, and a first threaded rod 404. The fixed plate 403 is fixed to the stage 402. The first threaded rod 404 is rotatably mounted on the fixed plate 403 and threadedly connected to it. The limiting rod 406 is parallel to one side of the first threaded rod 404 and is axially movable on the fixed plate 403. The clamping plate 405 is opposite to one side of the fixed plate 403 and movably connected to the first threaded rod 404, and fixedly connected to the limiting rod 406. During operation, the rotation of the first threaded rod 404 moves the clamping plate 405 closer to or further away from the fixed plate 403, thus completing the clamping or releasing action.

[0025] like Figure 4As shown, the annular slide 201 is located above the stage 402 and connected to the drive mechanism. It can move horizontally and vertically under the drive of the drive mechanism, with its horizontal displacement direction perpendicular to the sliding direction of the stage 402. Specifically, the drive mechanism includes a base 305, a horizontal drive mechanism, and a vertical drive mechanism. The base 305 is slidably mounted on the support frame 301, and the sliding direction of the base 305 is perpendicular to the moving direction of the stage 402. The horizontal drive mechanism is connected to the base 305 to drive the base 305 to move along its sliding direction, thereby adjusting the position of the welding torch 205 above the workpiece. The vertical drive mechanism is an electric push rod 306, whose telescopic rod 307 points downwards and is fixed to the annular slide 201, driving the annular slide 201 to rise and fall vertically, thereby adjusting the height of the welding torch 205.

[0026] Furthermore, the support frame 301 is provided with a limiting groove 304 perpendicular to the linear slide groove 401, and the base 305 is located within the limiting groove 304 and forms a sliding fit with the limiting groove 304. The horizontal drive mechanism includes a second threaded rod 303 and a motor 302 for driving the second threaded rod 303 to rotate; the second threaded rod 303 is rotatably mounted on the support frame 301 and connected to the motor 302 fixedly mounted on the support frame 301, and the second threaded rod 303 is threadedly connected to the base 305. During operation, the motor 302 drives the second threaded rod 303 to rotate, pushing the base 305 to slide within the limiting groove 304.

[0027] The slide block 203 is slidably mounted on the annular slide rail 201 and locked by a locking element. Specifically, the annular slide rail 201 includes a left annular portion and a right annular portion arranged opposite each other, and the opposite surfaces of the left and right annular portions are respectively provided with annular grooves 202 coaxial with them. The slide block 203 is located between the left and right annular portions, and both sides of it have sliding portions that are slidably installed in the annular grooves 202. The locking element includes a bolt 204, which is located between the left and right annular portions and threaded onto the slide block 203. The head of the bolt 204 is located inside the annular slide rail 201, and the radial width of the head is greater than the distance between the left and right annular portions. When the bolt 204 is tightened, its head is tightly pressed against the inner wall of the annular slide rail 201, so that the slide block 203 can no longer slide on the annular slide rail 201, thereby forming a lock. When the slide block 203 needs to slide, simply loosen the bolt 204 to separate its head from the inner wall of the annular slide rail 201.

[0028] When using this welding device, the workpiece is first placed between the clamping plate 405 and the fixed plate 403. Then, the first threaded rod 404 is turned to move the clamping plate 405 towards the fixed plate 403 under the guidance of the limiting rod 406 until the workpiece placed between them is clamped. Then, the bolt 204 is loosened to separate its head from the inner wall of the annular slide 201, so that the slide 203 enters a sliding state. At this time, the slide 203 is moved to slide circumferentially along the annular slide 201, thereby moving the welding torch 205. When the welding torch 205 is adjusted to the required welding angle, the bolt 204 is tightened so that its head is tightly pressed against the inner ring surface of the annular slide 201, so that the slide 203 can no longer move, and then it enters the locked state again.

[0029] Then, the motor 302 is turned on, which drives the second threaded rod 303 to rotate on the support frame 301. The rotation of the second threaded rod 303 pushes the base 305, along with the electric push rod 306 and the welding torch 205, to slide in the limiting groove 304. When the electric push rod 306 moves into position, the motor 302 is turned off, and the electric push rod 306 is started to push the annular slide 201 to move the welding torch 205 down to the part of the workpiece to be welded. When the welding torch 205 is in position, the electric push rod 306 is turned off, and then the welding torch 205 performs the welding work. During the welding process, it is only necessary to push the stage 402 to move along the linear slide.

[0030] As can be seen from the above, in this utility model, the stage 402 is linearly slidably mounted on the table surface of the worktable 1. A clamping component is mounted on the stage 402 for clamping the workpiece. The annular slide 201 is supported by a driving mechanism and can move horizontally and vertically under the drive of the driving mechanism. Its horizontal displacement direction is perpendicular to the sliding direction of the stage 402, thus forming a three-axis movement with the moving direction of the worktable 1. The slide block 203 is slidably mounted on the annular slide block 201, and the welding torch 205 is mounted on the slide block 203. During welding operations, by moving the slide block 203 along the annular slide block 201, the welding torch 205 can be precisely positioned to the required welding angle, ensuring the aesthetic appearance of the weld and meeting the process requirements. This method is suitable for various complex and irregular welding tasks.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
