[0001] This utility model belongs to the field of pipe welding technology, specifically an automatic argon arc welding station for stainless steel pipes. Background Technology

[0002] The stainless steel pipe argon arc welding station is a specialized work platform designed for the welding needs of stainless steel pipes. Its core function is to realize the argon arc welding operation of stainless steel pipes. It can stably fix the pipe to be welded to ensure the welding accuracy. At the same time, it is equipped with a welding system interface adapted to the argon arc welding process or directly integrates welding gun components. It can be used with an argon gas protection device to isolate air during the welding process, avoid weld oxidation, and reduce defects such as porosity and slag inclusions.

[0003] Since the stainless steel pipes to be welded vary in size and diameter, the position of the clamp needs to be adjusted according to the pipe diameter when clamping and fixing pipes of different diameters to ensure a good clamping effect. However, in some existing technologies, the position of the clamp is adjusted by rotating a threaded rod, which is cumbersome, reduces clamping efficiency, and causes hand fatigue for the operator. Therefore, an automatic argon arc welding station for stainless steel pipes is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, this utility model provides an automatic argon arc welding station for stainless steel pipes, including a welding station 100, and further including: an electric slide rail 400, on which a clamping mechanism 200 is provided; and a collection mechanism 300, which is provided on the top outer wall of the welding station 100. The clamping mechanism 200 includes a bracket 201, a slider 202 slidably connected to the inner wall of the bracket 201, a lever 203 fixedly connected to the outer wall of the slider 202, a moving block 205 hinged to the outer wall of the slider 202 via a hinge rod 204, a clamping plate 206 fixedly connected to the outer wall of the moving block 205, and a rubber pad 207 fixedly connected to the outer wall of the clamping plate 206.

[0017] The above solution employs the following: Clamping mechanism 200 is used to fix the stainless steel pipe to be welded. Two sets of clamping mechanisms 200 are provided, which can move laterally on the welding table 100 via an electric slide rail 400 (existing technology). After the stainless steel pipe is fixed in the clamping mechanism 200, both sets of clamping mechanisms 200 can move simultaneously towards the center, automatically aligning the welding surfaces of the two sets of stainless steel pipes. Welding is then performed via an argon arc welding head on the welding table 100. Two sets of clamping plates 206 can fix the stainless steel pipe. Rubber pads 207 contact the surface of the stainless steel pipe, increasing friction and ensuring a better clamping effect, preventing movement or rotation during welding. By adjusting the lever 203, the distance between the two sets of clamping plates 206 can be adjusted to accommodate stainless steel pipes of different diameters.

[0018] like Figures 2 to 3 As shown, the bracket 201 is slidably connected to the inner wall of the electric slide rail 400, and the lever 203 passes through the outer wall of the front end of the bracket 201; the two ends of the hinge rod 204 are respectively hinged to the outer walls of the moving block 205 and the slider 202, and the moving block 205 is slidably connected to the inner wall of the bracket 201.

[0019] Using the above scheme: the lever 203 can move up and down in the bracket 201, and drive the slider 202 to move synchronously. When the slider 202 moves, one end of the hinge rod 204 connected to it moves accordingly. The other end of the hinge rod 204 drives the moving block 205 to move. Since the moving block 205 can only move laterally along the inner wall of the bracket 201, the hinge rod 204 will flip, causing the moving blocks 205 on both sides and the clamping plate 206 to move simultaneously to the middle or both sides. This allows the spacing to be adjusted to accommodate stainless steel pipes of different diameters, and it eliminates the need to adjust the position of the clamping plate 206 by rotating the threaded rod. This is more convenient, faster, and easier to use, and improves the clamping efficiency.

[0020] like Figures 2 to 3 As shown, the clamping mechanism 200 also includes a plug rod 210, which is elastically connected to the inner wall of the lever block 203 by a connecting spring 209, and a slot 208 is provided on the outer wall of the bracket 201.

[0021] The above solution is adopted as follows: Under normal conditions, the insertion rod 210 is kept in a state of engagement with a set of slots 208 due to the elasticity of the connecting spring 209, which fixes the position of the toggle block 203 and the slider 202, and keeps the hinge rod 204, the moving block 205, and the clamping plate 206 fixed. There are multiple sets of slots 208, which are vertically distributed on the outer wall of the bracket 201. By moving the toggle block 203, the insertion rod 210 engages with different slots 208, which can fix the slider 202 in multiple positions, thereby fixing the spacing of the clamping plate 206 and ensuring the clamping effect on the stainless steel pipe.

[0022] like Figures 2 to 3 As shown, the insertion rod 210 is slidably connected to the inner wall of the lever 203, the insertion rod 210 is engaged with the slot 208, one end of the connecting spring 209 is fixedly connected to the outer wall of the insertion rod 210, and the other end of the connecting spring 209 is fixedly connected to the inner wall of the lever 203.

[0023] Using the above scheme: the insertion rod 210 can be manually pulled outward to stretch the connecting spring 209 and disengage the insertion rod 210 from the slot 208. At this time, the limit contact of the toggle block 203 can be made, and the spacing of the clamping plate 206 can be adjusted. When the toggle block 203 moves upward, the hinge rod 204 flips to both sides, and the two sets of moving blocks 205 move to both sides. Conversely, when the toggle block 203 moves downward, the moving blocks 205 on both sides move to the middle at the same time.

[0024] like Figure 4 As shown, the collection mechanism 300 includes a waste bin 301, a door panel 302 is hinged to the outer wall of the waste bin 301, a pressure plate 304 is elastically connected to the inner wall of the waste bin 301 through a return spring 303, and a handle 306 is hinged to the outer wall of the pressure plate 304 through a connecting rod 305.

[0025] The above solution is adopted as follows: the outer wall of the waste slag box 301 is equipped with a dust suction head. The dust suction head can use an air pump to suck the waste slag generated by welding on the welding table 100 into the waste slag box 301 for collection. After the waste slag box 301 is full of waste slag, the door panel 302 can be opened to process the waste slag inside. The side wall of the pressure plate 304 is completely attached to the inner wall of the waste slag box 301, and it can only move up and down within the inner wall of the waste slag box 301. When the pressure plate 304 is pressed down, it can compact the waste slag, reduce its space occupation, and prevent the waste slag box 301 from being easily filled due to its loose texture. This reduces the frequency of cleaning the waste slag box 301 by the operator.

[0026] like Figure 4 As shown, the waste chip box 301 is fixedly connected to the top outer wall of the welding table 100. One end of the return spring 303 is fixedly connected to the outer wall of the pressure plate 304, and the other end of the return spring 303 is fixedly connected to the inner wall of the waste chip box 301. The pressure plate 304 is slidably connected to the inner wall of the waste chip box 301. The two ends of the connecting rod 305 are respectively hinged to the handle 306 and the outer wall of the pressure plate 304. The handle 306 is slidably connected to the inner wall of the waste chip box 301.

[0027] Using the above solution: Under normal conditions, the door panel 302 remains in the upper position due to the elasticity of the return spring 303. The operator can move the handle 306 horizontally, causing the upper end of the connecting rod 305 to move. The lower end of the connecting rod 305 will push the pressure plate 304 downward, and the connecting rod 305 will flip itself. After the pressure plate 304 moves downward, it can compact the waste. When the pressure plate 304 moves to the bottom, it is still above the vacuum head, so the waste will not be sucked to the upper part of the pressure plate 304. When the pressure plate 304 moves downward, the return spring 303 will be stretched by force. After compacting the waste once, the handle 306 can be released. The tension of the return spring 303 will drive the pressure plate 304 to move upward and reset, returning to the initial state.

[0028] Working principle and usage process of this utility model: The operator can first manually pull the insertion rod 210 outward to disengage it from the slot 208, release the limit of the lever 203, and then push the lever 203 upward to move the slider 202 upward simultaneously. The hinge rod 204 flips to move the moving block 205 and the clamping plate 206 to both sides, increasing the distance between the two sets of clamping plates 206. Then, the stainless steel pipe to be welded is placed between the two sets of clamping plates 206, and the lever 203 is pushed downward. The hinge rod 204 pulls the moving blocks 205 and the clamping plates 206 on both sides toward the middle. When the rubber pad 207 is in contact with the outer wall of the pipe, the insertion rod 210 is released, and the connecting spring 209 drives it to lock into the corresponding slot 208, fixing the position of the lever 203 and the clamping plate 206, thus completing the clamping and fixing of a set of pipes. The efficiency is high and the operation is relatively simple.

[0029] Then repeat the above steps to fix another set of stainless steel pipes to be welded in the second set of clamping mechanisms 200. Start the electric slide rail 400 through the control system. The two sets of clamping mechanisms 200 move synchronously towards the middle along the guide rail of the electric slide rail 400. Stop the electric slide rail 400 when the welding surfaces are in complete contact to complete the automatic seam alignment.

[0030] At this point, the butt joint of the two sets of pipes can be welded using an argon arc welding torch. Simultaneously with the start of welding, the air pump of the collection mechanism 300 is activated. Welding slag and metal chips generated during welding are sucked into the waste chip box 301 through the suction head. Because the waste chips are loosely packed, the waste chip box 301 occupies space too quickly. After each welding operation, the operator can pull the handle 306, which, through the connecting rod 305, flips and pushes the pressure plate 304 downwards to compact the loose waste chips inside the waste chip box 301. After compaction, the handle 306 is released, and the return spring 303 drives the pressure plate 304 back to its initial state. When the waste chips in the waste chip box 301 are compacted and relatively full, the door panel 302 can be opened to process the waste chips, avoiding the need to clean the waste chips after each welding operation. This unified cleaning reduces the frequency of operation.
