Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, specifically an automatic arc welding device and welding method for gas-filled cabinets. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes various energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. However, in current technology, welding of existing gas-insulated switchgear is mostly done manually, resulting in low actual welding efficiency. Furthermore, the welding process of existing gas-insulated switchgear easily generates a large amount of particulate metal oxides, forming fumes that disperse into the air. These fumes also contain harmful gases produced by combustion aids, polluting the operating environment and harming personnel health. Additionally, with the increasing number of welded structures in gas-insulated switchgear, adjusting the welding position becomes inconvenient, leading to unsatisfactory welding results.

[0018] An automatic arc welding method for gas-insulated switchgear includes the following steps:

[0019] S1. Welding Preparation: Based on the actual usage environment, protective plates and movable frames can be added or removed to allow the protective plates, movable frames, connecting blocks, and connecting frames to work together to form a certain welding area with the first and second movable plates. Then, according to the specifications of the gas cabinet to be welded, the distance between the first and second adjustment frames can be adjusted. At the same time, by rotating and adjusting the second positioning rod, the second positioning plate can press the base to fix the positions of the first and second adjustment frames. Then, by controlling the start of the adjustment motor, the adjustment motor can work with the first moving threaded rod to move the movable seat to the area between the first and second adjustment frames. By adding or removing top blocks, the first top bar, and the second top bar, the spliced ​​first and second top bars can be positioned above the first and second adjustment frames. Then, under the restriction of the position of the limit ring, the extension tube and connecting tube can be easily adjusted so that the suction frame can be positioned between the first and second adjustment frames, thus completing the pre-welding preparation.

[0020] S2. Welding Process: Place one end of the gas cabinet component to be welded on the top of the lifting tube. Then, start the connecting motor to drive the connecting shaft to rotate. The rotating connecting shaft, through the connecting groove and the locking strip and slot, synchronously drives the corresponding first bevel gear to rotate. The rotating first bevel gear, in conjunction with the second bevel gear, extension shaft, extension worm, and extension worm wheel, drives the two lifting threaded rods to rotate synchronously. The rotating lifting threaded rods, in conjunction with the lifting plate and lifting bar, raise the working height of the lifting tube, allowing the lifting tube to easily raise the height of the gas cabinet component to be welded until the bottom of the gas cabinet component is higher than the top of the support tube. At this point, push the gas cabinet component to be welded towards the top of the support tube, allowing the support tube to stably support the gas cabinet component. Then, by moving the first and second adjusting frames, the two rotating frames can gradually approach the gas cabinet to be welded. At both ends of the component, the adjusting worm gear is rotated to drive the corresponding bidirectional threaded rod to rotate. The rotating bidirectional threaded rod, in turn, drives the clamping plate to gradually fit against the outer surface of the gas cabinet component to be welded, so that the gas cabinet component to be welded can be stably placed on the top of the support tube. Then, by controlling the start of the moving motor, the moving motor, in conjunction with the second moving threaded rod, moves the moving seat closer to the gas cabinet component to be welded, so that the welding robot body can efficiently perform the welding process of the gas cabinet component to be welded. At the same time, by rotating the rotating worm gear, the rotating worm gear, in conjunction with the rotating worm wheel, drives the corresponding rotating frame to rotate. Under the position restriction of the clamping plate, the rotating frame can easily adjust the placement angle of the gas cabinet component to be welded. At the same time, by rotating the adjustable limit thread cap, the limit nut can support the adjustable support tube to support and fit against the bottom of the gas cabinet component to be welded.

[0021] S3. Environmental Protection: By controlling the start of the fume purifier, the fume purifier can extract air from the welding position in real time through the extension pipe, connecting pipe and suction frame. This ensures that harmful gases generated during welding can be promptly extracted into the fume purifier for treatment, and that the air inside the welding area formed by the protective plate, movable frame, connecting block and connecting frame, and the first and second movable plates does not easily diffuse to the surroundings.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] (1) In this invention, during use, one end of the gas cabinet component to be welded is placed on the top of the lifting pipe. Then, by controlling the start of the linkage motor, the linkage motor can drive the linkage shaft to rotate. The rotating linkage shaft, through the linkage groove, can synchronously drive the corresponding first bevel gear to rotate through the locking strip and the locking groove. The rotating first bevel gear, in conjunction with the second bevel gear, the extension shaft, the extension worm, and the extension worm wheel, can drive the two lifting threaded rods to rotate synchronously. The rotating lifting threaded rods, in conjunction with the lifting plate and the lifting strip, can raise the working height of the lifting pipe, so that the lifting pipe can easily raise the height of the gas cabinet component to be welded until the bottom of the gas cabinet component to be welded is higher than the top of the support pipe. At this time, the gas cabinet component to be welded is pushed towards the top of the support pipe, so that the support pipe can stably support the gas cabinet component to be welded. Then, by moving the first adjustment frame and the second adjustment frame, the two rotating frames can gradually approach the two ends of the gas cabinet component to be welded. Then, by rotating the adjusting worm, the adjusting worm, in conjunction with the adjusting worm wheel, can drive the gas cabinet component to rotate. The bidirectional threaded rod rotates, causing it to work with the adjusting plate to gradually bring the clamping plate into contact with the outer surface of the gas-insulated cabinet component to be welded. This allows the component to be stably placed on top of the support tube. Then, by controlling the start of the moving motor, the moving motor, in conjunction with the second moving threaded rod, moves the moving seat closer to the component, enabling the welding robot to efficiently weld it. Simultaneously, by rotating the rotating worm gear, which in turn drives the corresponding rotating frame to rotate, the angle of the rotating frame can be easily adjusted under the constraint of the clamping plate. Furthermore, by rotating and adjusting the height of the limiting threaded cap, the limiting cap supports the adjusting support tube, ensuring it is in contact with the bottom of the component, allowing for easy adjustment of its position. This ensures the equipment efficiently welds the gas-insulated cabinet component and effectively performs its intended functions.

[0024] (2) In this invention, by controlling the start of the fume purifier body, the fume purifier body can perform real-time air extraction treatment at the welding position through the extension pipe, connecting pipe and suction frame, so that the harmful gases generated during the welding process can be extracted into the fume purifier body for treatment in a timely manner, ensuring that the air inside the welding area formed by the protective plate, movable frame, connecting block and connecting frame with the first movable plate and the second movable plate is not easily diffused to the surroundings, thereby improving the safety of actual welding.

The two support tubes 125 are slidably sleeved on the outer surface of the corresponding support rod 124. The welding components include a movable seat 103, a platform 108, and a welding robot body 109. The movable seat 103 is slidably sleeved on the outer surface of the corresponding top plate 102, and the movable seat 103 is threadedly connected to the first movable threaded rod 110. Multiple movable wheels 104 are rotatably connected between the inner surface walls on both sides of the movable seat 103, and the bottom of each movable wheel 104 is in contact with the top of the corresponding top plate 102. Multiple support wheels 105 are equidistantly rotatably connected to the inner surface walls on both sides of the movable seat 103. The platform 108 is slidably embedded inside the movable seat 103, and the bottom of the platform 108 is in contact with the tops of the multiple support wheels 105. The suction components include a welding fume purifier body 112, an extension tube 113, a connecting tube 114, and a suction frame 116. The body 112 is fixedly connected to one side of the base 101. The extension tube 113 is connected to the input end of the dust purifier body 112. The connecting tube 114 is fixedly connected to one end of the extension tube 113.

Simultaneously, by rotating the second positioning rods 213, the second positioning pieces 214 press against the base 101 to fix the positions of the first adjusting frame 201 and the second adjusting frame 202. By moving the first adjusting frame 201 and the second adjusting frame 202, the two rotating frames 203 gradually approach the two ends of the gas-filled cabinet component to be welded. Then, by rotating the adjusting worm 207, the adjusting worm 207, in conjunction with the adjusting worm gear, drives the corresponding bidirectional threaded rod 204 to rotate, thereby allowing the rotating bidirectional threaded rod 204 to engage with the adjusting piece 210. 05. The clamping plate 206 gradually adheres to the outer surface of the gas-insulated cabinet component to be welded, allowing the component to be stably placed on top of the support tube 125. Then, by controlling and activating the moving motor 107, the moving motor 107, in conjunction with the second moving threaded rod 106, moves the moving seat 103 closer to the gas-insulated cabinet component, enabling the welding robot body 109 to efficiently weld the component. Simultaneously, by rotating the rotating worm gear 208, which, in conjunction with the rotating worm wheel, drives the corresponding rotating frame 203 to rotate, the rotating frame 203, under the positional constraint of the clamping plate 206, can easily adjust the placement angle of the gas-insulated cabinet component. Furthermore, by rotating and adjusting the height of the limiting threaded cap, the limiting cap can support and adjust the support tube 125 to adhere to the bottom of the gas-insulated cabinet component, allowing for convenient adjustment of its placement position and enabling the equipment to efficiently weld the component.

[0053] Please see Figure 18 and Figure 19The protective mechanism 3 is used to separate the welding area and includes a protective plate 301, a movable frame 304, a first movable plate 305, a second movable plate 306, and a top block 307. A connecting block 302 and a connecting frame 303 are fixedly connected to the outer surface of the protective plate 301. The first movable plate 305 and the second movable plate 306 are rotatably connected to the outer surface of the movable frame 304. A connecting block 302 is also fixedly connected to the outer surface of the first movable plate 305, and a connecting frame 303 is fixedly connected to the outer surface of the second movable plate 306. The top block 307 is slidably inserted into the top of the protective plate 301. Two first top bars 308 slide through one side of the outer surface of the top block 307. A second top bar 309 is fixedly connected to one end of each first top bar 308 by bolts. Based on the actual usage environment, the protective plate 301 and the movable frame 304 can be added or removed, so that the protective plate 301, the movable frame 304, the connecting block 302 and the connecting frame 303 can cooperate to form a certain welding area separation between the first movable plate 305 and the second movable plate 306. By adding or removing the top block 307, the first top bar 308 and the second top bar 309, the spliced ​​first top bar 308 and the second top bar 309 can be positioned above the first adjustment frame 201 and the second adjustment frame 202. Then, under the position restriction of the limiting ring 115, the extension tube 113 and the connecting tube 114 can be easily adjusted, so that the suction frame 116 can be positioned between the first adjustment frame 201 and the second adjustment frame, thereby completing the pre-welding preparation process.

[0054] The following provides a detailed description of an automatic arc welding method for a gas-filled cabinet according to an embodiment of the present invention. The method of use includes the following steps:

[0055] Step 1, Welding Preparation: Based on the actual usage environment, the protective plate 301 and movable frame 304 can be added or removed. This allows the protective plate 301, movable frame 304, connecting block 302, and connecting frame 303 to cooperate with the first movable plate 305 and second movable plate 306 to form a certain welding area separation. Then, according to the specifications of the gas inflator to be welded, the distance between the first adjusting frame 201 and the second adjusting frame 202 is adjusted. Simultaneously, by rotating and adjusting the second positioning rod 213, the second positioning piece 214 can press against the base 101 to fix the positions of the first adjusting frame 201 and the second adjusting frame 202. Finally, by controlling... Start the adjustment motor 111 so that the adjustment motor 111 can work with the first moving threaded rod 110 to move the moving seat 103 to the area between the first adjustment frame 201 and the second adjustment frame 202. By adding or removing the top block 307, the first top bar 308 and the second top bar 309, the spliced ​​first top bar 308 and the second top bar 309 can be located above the first adjustment frame 201 and the second adjustment frame 202. Then, under the position restriction of the limiting ring 115, the extension tube 113 and the connecting tube 114 can be easily adjusted so that the suction frame 116 can be located between the first adjustment frame 201 and the second adjustment frame, thereby completing the pre-welding preparation process.

[0056] Step 2, Welding Process: Place one end of the gas-insulated cabinet component to be welded on top of the lifting pipe 220. Then, start the connecting motor 118 to drive the connecting shaft 117 to rotate. The rotating connecting shaft 117, through the connecting groove and the locking strip 119, synchronously drives the corresponding first bevel gear 216 to rotate. The rotating first bevel gear 216, in conjunction with the second bevel gear 218, the extension shaft 217, the extension worm 210, and the extension worm wheel, drives the two lifting threaded rods 209 to rotate synchronously. The rotating lifting threaded rods 209 cooperate with the lifting... Plate 211 and lifting bar 219 can raise the working height of lifting pipe 220, allowing lifting pipe 220 to easily raise the height of the gas cabinet component to be welded until the bottom of the gas cabinet component to be welded is higher than the top of support pipe 125. At this time, the gas cabinet component to be welded is pushed towards the top of support pipe 125, so that support pipe 125 can stably support the gas cabinet component to be welded. Then, by moving the first adjusting frame 201 and the second adjusting frame 202, the two rotating frames 203 can gradually approach the two ends of the gas cabinet component to be welded. Finally, by rotating adjusting worm gear 207, adjusting worm gear 207 can be adjusted... 07, in conjunction with the adjusting worm gear, drives the corresponding bidirectional threaded rod 204 to rotate. This rotating bidirectional threaded rod 204, in conjunction with the adjusting plate 205, causes the clamping plate 206 to gradually contact the outer surface of the gas-insulated cabinet component to be welded. This allows the gas-insulated cabinet component to be stably placed on top of the support tube 125. Then, by controlling and activating the moving motor 107, the moving motor 107, in conjunction with the second moving threaded rod 106, moves the moving seat 103 closer to the gas-insulated cabinet component. This enables the welding robot body 109 to efficiently perform the welding of the gas-insulated cabinet component. Simultaneously, through… By rotating the worm gear 208, the worm gear 208, in conjunction with the worm wheel, can drive the corresponding rotating frame 203 to rotate. Under the position restriction of the clamping plate 206, the rotating frame 203 can easily adjust the placement angle of the gas cabinet component to be welded. At the same time, by rotating and adjusting the height of the limiting thread cap, the limiting nut can support the adjusting support tube 125 to support and fit against the bottom of the gas cabinet component to be welded. This allows the placement position of the gas cabinet component to be welded to be easily adjusted, enabling the equipment to efficiently perform the welding process of the gas cabinet component and efficiently realize its intended functions.

[0057] Step 3, Environmental Protection: By controlling the activation of the fume purifier body 112, the fume purifier body 112 can perform real-time air extraction at the welding position through the extension pipe 113, connecting pipe 114, and suction frame 116. This ensures that harmful gases generated during the welding process can be promptly extracted into the fume purifier body 112 for treatment. This ensures that the air inside the welding area formed by the protective plate 301, the movable frame 304, the connecting block 302, and the connecting frame 303, along with the first movable plate 305 and the second movable plate 306, does not easily diffuse to the surroundings, thus improving the safety of the actual welding process.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Then, by rotating the adjusting worm gear (207), the adjusting worm gear (207) and adjusting worm wheel can drive the corresponding bidirectional threaded rod (204) to rotate. This allows the rotating bidirectional threaded rod (204) to work with the adjusting plate (205) to drive the clamping plate (206) to gradually fit against the outer surface of the gas-filled cabinet component to be welded. This allows the gas-filled cabinet component to be welded to be placed stably on top of the support tube (125).

At the same time, by rotating the rotating worm (208), the rotating worm (208) and the rotating worm wheel can drive the corresponding rotating frame (203) to rotate. Thus, under the position restriction of the clamp (206), the rotating frame (203) can conveniently adjust the placement angle of the gas cabinet component to be welded.
