[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figure 1 Figure 1 , an embodiment provided by the present utility model: a stainless - steel welding device, including a mounting base 1. An installation frame 2 is fixedly connected inside the mounting base 1. A movable welding assembly 3 is arranged on the inner top surface of the installation frame 2. The movable welding assembly 3 includes: a moving assembly and a welding device. The moving assembly can drive the welding device to perform linear movement in the up - down and front - back directions, and can quickly realize the welding between stainless - steel parts, thereby improving the processing efficiency and safety. A clamping assembly is arranged above the mounting base 1.

[0035] Referring to Figures 1 - 3 Figures 1 - 3 , the clamping assembly includes: a motor 401, a clamping frame 405, and a bolt 408. The motor 401 is fixedly connected to the right - hand surface of the mounting base 1. The left - hand output end of the motor 401 penetrates through the right - hand surface of the mounting base 1. A bidirectional lead screw 402 is fixedly connected to the left - hand output end of the motor 401. When the motor 401 is started, it can drive the bidirectional lead screw 402 to rotate. The left end of the bidirectional lead screw 402 is rotatably connected to the inner left - hand wall surface of the mounting base 1. Moving plates 403 are threadedly connected to both the left and right ends of the bidirectional lead screw 402. The bottom surface of the moving plate 403 is in mutual contact with the inner bottom surface of the mounting base 1. The inner wall of the mounting base 1 can guide and limit the movement of the moving plate 403, so that the moving plate 403 can only perform linear movement in the left - right direction. When the bidirectional lead screw 402 rotates, it can drive the two moving plates 403 to perform synchronous linear movement in opposite directions.

[0036] A support rod 404 is detachably installed on the side surface of the moving plate 403 close to the installation frame 2. The clamping frame 405 is fixedly connected to the end of the support rod 404 away from the moving plate 403. When the moving plate 403 moves, it can drive the clamping frame 405 to move synchronously through the support rod 404. The clamping frame 405 is integrally arranged in a 45° inclined structure. A limiting rod 406 is fixedly connected to the bottom end of the rear - side inner wall of the clamping frame 405. The number of the limiting rods 406 is several. The several limiting rods 406 are fixedly connected in a linear array inside the clamping frame 405. The limiting rods 406 can limit and support the stainless - steel parts placed inside the clamping frame 405. At the same time, there is a gap between two adjacent limiting rods 406, which can enable the welding slag entering the inside of the clamping frame 405 to directly fall through the gap, avoiding accumulation inside the clamping frame 405 and causing obstruction to the movement of the clamping plate 409.

[0037] A chute 407 is provided at the center of the upper surface of the limit rod 406. The bolt 408 is arranged on the side of the clamping frame 405 away from the support rod 404. One end of the bolt 408 close to the clamping frame 405 penetrates through the clamping frame 405. The bolt 408 is threadedly connected to the inner wall of the clamping frame 405. One end of the bolt 408 close to the clamping frame 405 is rotatably connected to a clamping plate 409. A rubber pad is fixedly connected to the surface of the clamping plate 409 away from the bolt 408. The rubber pad can avoid the hard contact between the clamping plate 409 and the stainless steel part, thereby avoiding the clamping damage or wear of the stainless steel part. A limit block 410 is fixedly connected to the bottom end of the clamping plate 409. The limit block 410 is slidably connected to the inside of the chute 407. The limit block 410 can perform linear motion inside the chute 407. Through the cooperation of the provided limit block 410 and chute 407, the movement of the clamping plate 409 can be guided and limited, so that the clamping plate 409 can maintain linear motion inside the clamping frame 405. When the bolt 408 rotates, it can drive the clamping plate 409 to move towards the stainless steel part, thereby clamping and fixing the stainless steel part, realizing the rapid positioning of the stainless steel part, and at the same time making the stainless steel part maintain an inclined state of 45°. When the stainless steel parts on both sides approach and fit together, a right-angle stainless steel part can be formed. Furthermore, the movable welding assembly 3 can be used to quickly weld the stainless steel parts at the right angle.

[0038] Refer to Figures 2 - 4 , a limit groove 501 is provided on the surface of the moving plate 403 close to the mounting frame 2. One end of the support rod 404 close to the moving plate 403 is inserted into the inside of the limit groove 501. A clamping groove 502 is provided on the upper surface of the support rod 404. A moving block 503 is arranged at the upper end of the moving plate 403. A clamping rod 504 is fixedly connected to the bottom end of the moving block 503. The bottom end of the clamping rod 504 penetrates through the moving plate 403. The bottom end of the clamping rod 504 is clamped in the inside of the clamping groove 502. In the initial state, the bottom end of the clamping rod 504 is located inside the clamping groove 502, and the support rod 404 can be clamped and fixed. A spring 505 is sleeved on the outside of the clamping rod 504. The top end of the spring 505 is fixedly connected to the bottom surface of the moving block 503. The bottom end of the spring 505 is fixedly connected to the upper surface of the moving plate 403. When the moving block 503 moves upward, it can drive the clamping rod 504 to move synchronously away from the clamping groove 502 and pull the spring 505, so that the spring 505 is stretched to generate elastic potential energy. At this time, the clamping and fixing of the support rod 404 can be released, so that the support rod 404 can be quickly pulled out and replaced. When positioning and welding two spliced stainless steel plates, the support rod 404 with a vertical clamping part can be replaced, inserted into the inside of the limit groove 501, and the moving block 503 is released, so that the clamping rod 504 moves downward and resets under the action of the elastic potential energy of the spring 505, and quickly inserts into the inside of the clamping groove 502 to complete the clamping and fixing of the new clamping part, and the operation is simple.

[0039] Working principle: Place the stainless steel parts for right-angle welding into the interior of the clamping bracket 405. Then, rotate the bolt 408 to drive the clamping plate 409 to move and clamp and limit the stainless steel parts, so that the stainless steel parts are set in a 45° inclined state. Subsequently, start the motor 401 to drive the stainless steel parts on both sides to approach each other to form a right-angle structure. Furthermore, the welding operation can be quickly carried out through the movable welding assembly 3. During the welding process, the welding slag that enters the interior of the clamping bracket 405 can fall through the gaps between the limiting rods 406 to avoid hindering the movement of the clamping plate 409. When it is necessary to clamp, position and weld stainless steel parts of other shapes, the moving block 503 can be pulled up to quickly release the clamping limit on the support rod 404. Then, insert the new support rod 404 with the required clamping parts into the limit slot 501 and release the moving block 503 to quickly complete the replacement of the clamping parts, and the operation is simple and convenient.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
