Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a protection device for welding stainless steel welded pipes, including:

[0022] A workbench 1, on the top of the workbench 1, there are multiple groups of jigs for fixing the position of the stainless steel welded pipe during welding operations and cutting operations. On the top of the workbench 1, there is a welding piece 101, and the welding head of the welding piece 101 is aligned with the welding position of the stainless steel welded pipe to weld it. On the top of the workbench 1, a bracket 201 is fixedly arranged, and a hydraulic component is fixedly installed on the top of the bracket 201. The output end of the hydraulic component at the bottom is fixedly provided with a connecting plate 202. A driving motor is arranged on the outer wall of the connecting plate 202, and one end of the output end of the driving motor is fixedly provided with a cutting knife 2. When two stainless steel welded pipes are welded together and the ends of the two stainless steel welded pipes are uneven, the uneven part is cut off by the cutting knife 2 to facilitate the subsequent alignment and welding of the two stainless steel welded pipes. A protection component is arranged on the outer wall of the cutting knife 2, and the protection component includes:

[0023] A rotating unit, which is used to adjust the exposed state of the cutting knife 2, and the rotating unit includes a protective cover 3 and a rotating cover 304. The protective cover 3 is fixedly arranged on the outer wall of the connecting plate 202, and the protective cover 3 is sleeved on the top of the cutting knife 2. The rotating cover 304 is rotatably connected to the inner wall of the protective cover 3 through a pin shaft, and the rotating cover 304 is sleeved on the outer wall of the cutting knife 2. During the welding operation, the user rotates the rotating cover 304 downward to wrap and block the lower part of the cutting knife 2, so as to play a protective role for the cutting knife 2, reduce the damage of the welding piece 101 to the cutting knife 2 during welding, and improve the service life of the cutting knife 2;

[0024] A positioning unit, which is arranged on the outer wall of the rotating cover 304 and is used to fix the use position of the rotating cover 304.

[0025] A sliding groove 301 is opened on the outer wall of the protective cover 3, and a sliding block 305 is fixedly arranged on the outer wall of the rotating cover 304, and the sliding block 305 is movably clamped in the inner wall of the sliding groove 301 to limit the rotation path and rotation range of the rotating cover 304.

[0026] The positioning unit includes a positioning block 302, a connecting block 306 and a moving block 307. The positioning block 302 is fixedly arranged on the outer wall of the protective cover 3, and a clamping groove 303 is formed on the outer wall of the positioning block 302. There are two groups of the positioning block 302 and the clamping groove 303, and they are symmetrically distributed on both sides of the protective cover 3. The connecting block 306 is fixedly arranged on the outer wall of the slider 305, and the moving block 307 is inserted through the outer wall of the connecting block 306. A connecting groove 308 is formed on the outer wall of the moving block 307, and a clamping block 310 is movably clamped on the inner wall of the connecting groove 308. The outer end of the clamping block 310 is butted and clamped in the corresponding clamping groove 303. A spring strip 309 is fixedly arranged on the inner wall of the connecting groove 308, and the other end of the spring strip 309 is fixedly arranged on the outer wall of the clamping block 310. When the rotating cover 304 wraps and shields the cutting tool 2, the moving block 307 is aligned with the positioning block 302. By pushing the moving block 307 downward, the bottom of the moving block 307 is inserted into the positioning block 302. And when the clamping block 310 is aligned with the clamping groove 303, the clamping block 310 is pushed outward by the driving force of the spring strip 309, so that the clamping block 310 is inserted and clamped in the clamping groove 303, so as to fix the position of the connecting block 306, thereby fixing the position of the rotating cover 304, facilitating the protection of the cutting tool 2. And when the cutting tool 2 needs to be used, the user pushes the clamping block 310 inward through the clamping groove 303, so that the clamping block 310 is separated from the clamping groove 303. At this time, the moving block 307 is pulled upward, so that the moving block 307 moves away from the positioning block 302. By continuously pulling the moving block 307 backward, the slider 305 and the rotating cover 304 are driven to rotate backward, so that the rotating cover 304 rotates above the cutting tool 2. At this time, the lower part of the cutting tool 2 is exposed, so as to cut the stainless steel welded pipe with uneven ends during welding. And there are two groups of the connecting groove 308, the clamping block 310 and the spring strip 309, which are symmetrically distributed on the moving block 307. After the rotating cover 304 rotates above the cutting tool 2, similarly, the other group of clamping blocks 310 are clamped in the clamping grooves 303 of the other group of positioning blocks 302, so as to fix the position of the rotating cover 304 and prevent the rotating cover 304 from sliding down during the cutting operation.

[0027] A baffle 4 is fixedly arranged on the top of the workbench 1, and a turning plate 401 is rotatably connected to the outer wall of the baffle 4 through a hinge to protect the workbench 1 and further improve safety.
