[0002] Electricity iron fittings are indispensable metal components in the power transmission and distribution network, encompassing various auxiliary supports, connections, and fixing parts from high-voltage transmission lines to low-voltage distribution facilities, including cable supports for supporting and fixing cables.

[0003] Chinese patent CN207013894U discloses a cable bracket welding workbench, which has the following advantages: it only requires fixing the main cable bracket and workpiece to the fixing device for welding, avoiding manual fixing, ensuring stability during welding, reducing welding difficulty, improving welding quality, and reducing the defect rate; using the fixing device for positioning reduces the risk of work-related injuries from manual fixing; the beam frame is fixed and can be automatically flipped, avoiding manual flipping welding and improving work efficiency.

[0004] However, this technical solution still has at least the following drawbacks: when welding multiple cable supports, the complex operation method makes it impossible to achieve welding quickly, thus reducing welding efficiency. Therefore, this invention is proposed. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0043] Example 1

[0044] like Figures 1 to 15 As shown, a welding apparatus for electric iron accessories includes:

[0045] The mobile unit includes a base 100 and a storage bin 102, and a moving mechanism is provided between the storage bins 102;

[0046] The pushing unit includes a guiding mechanism and a conversion mechanism. The guiding mechanism includes guide plates 300 on both sides of the base 100, and a guide wheel 308 is provided on one side of the guide plate 300. The conversion mechanism includes a conversion component and a second gear 201. The guide wheel 308 moves horizontally under the action of the guide plate 300 and then rotates the second gear 201 after passing through the conversion component.

[0047] like Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, in a specific embodiment, the pushing unit further includes a pushing mechanism, which is located above the conversion mechanism and connected to the guide wheel 308. This allows the guide wheel 308 to move, thereby driving the conversion mechanism to move. The pushing mechanism is equipped with a reset component. When the guide wheel 308 loses the support of the guide plate 300, it is reset by the reset component, and the conversion mechanism remains stationary during the reset. The conversion component includes a support platform 204, and a connecting shaft 202 is movably inserted into the support platform 204. The bottom of the connecting shaft 202 is fixedly connected to the second gear 201, and a rotating column 203 is fixedly installed on the top. An elastic element is movably inserted into the rotating column 203. A guide groove 205 is provided on the support platform 204, and the guide groove 205 includes an inclined surface 206 and a horizontal surface 207. When the elastic element slides in the guide groove 205, it moves upward under the action of the inclined surface 206. In this configuration, there are three elastic elements. When the rotating column 203 is not rotating, the three elastic elements are located at both ends and the middle part of the guide groove 205, forming an equilateral triangle. The elastic element located in the middle part is on the horizontal plane 207. The elastic element in the middle part only enters the inclined plane 206 when the elastic element pushed by the lower plate 211 moves beyond the position where the inclined plane 206 and the horizontal plane 207 meet, so as to prevent the elastic element in the middle part from rising before entering the bottom of the lower plate 211.

[0048] like Figure 8 As shown, the elastic element further includes an outer tube 208 and an inner tube 209 that are nested together, and a first spring 210 is installed between the outer tube 208 and the inner tube 209. When the elastic element slides in the guide groove 205, the inner tube 209 rises along the inclined surface 206 to compress the elastic element as a whole. In this configuration, a protrusion is provided between the outer tube 208 and the inner tube 209 to prevent the outer tube 208 and the inner tube 209 from separating.

[0049] like Figures 10 to 12 As shown, the pushing mechanism further includes a lower plate 211 and an upper plate 212 fixedly connected to each other. When the lower plate 211 moves, it abuts against the elastic element to drive the rotating column 203 to rotate. The pushing mechanism also includes a slide rail 214, on which a first slider 213 and a second slider 311 are slidably connected. A pull rod 310 is installed between the first slider 213 and the second slider 311. A connecting frame 309 is fixedly installed at one end of the pull rod 310, and a guide wheel 308 is installed on the connecting frame 309. In this configuration, the second slider 311 supports the connecting frame 309, thereby increasing the stability of the connecting frame 309 and preventing it from causing the center of gravity of the first slider 213 to shift, which would lead to increased wear on one side.

[0050] like Figure 10 , Figure 11 , Figure 13As shown, further, side base plates 103 are fixedly installed on both sides of the top of the storage bin 102, and fixed brackets 215 are fixedly installed on both sides of the ends of the side base plates 103. The slide rail 214 is fixedly connected to the fixed brackets 215, and fixed members 216 are fixedly installed at both ends of the slide rail 214. The reset assembly includes a first fixed rod 217 fixedly installed between the two fixed members 216. A connecting block 219 is movably sleeved on the first fixed rod 217, and the connecting block 219 is fixedly connected to the upper plate 212. A second spring 218 is movably sleeved on the first fixed rod 217. The elastic force of the second spring 218 acts on the connecting block 219 to reset the upper plate 212 and the lower plate 211. In this configuration, the guide plate 300 consists of an inclined section, a vertical section, and a horizontal section. When the guide wheel 308 moves along the inclined section, the second spring 218 is compressed. When the guide wheel 308 moves from the horizontal section into the vertical section, the elastic force of the second spring 218 is released and drives the connecting block 219 to reset, so that the lower plate 211 and the upper plate 212 are reset.

[0051] like Figure 5 , Figure 6 , Figure 10 As shown, further, a connecting plate 220 is fixedly installed on one side of the support platform 204. A second fixing rod 222 is movably inserted into the connecting plate 220. Fixing plates 223 are fixedly installed at both ends of the second fixing rod 222. The fixing plates 223 are fixedly connected to both ends of the storage bin 102. A rack 200 is fixedly installed on the top of the side base plate 103, and the rack 200 meshes with the second gear 201. A push rod 221 is fixedly installed on the connecting plate 220. A groove 106 is opened on the top of the storage bin 102. The push rod 221 moves through the groove 106 and extends into the interior of the storage bin 102. In this configuration, the second fixing rod 222 supports the connecting plate 220, and the support platform 204 is connected to the connecting plate 220 to prevent the support platform 204 from rotating.

[0052] like Figure 3 As shown, furthermore, an adjustment mechanism is provided at the bottom of the guide mechanism. The adjustment mechanism includes support frames 302 fixedly installed on both sides of the base 100, and support columns 301 are movably connected to the support frames 302. The support columns 301 are fixedly connected to the guide plate 300. The adjustment mechanism also includes support members 304 fixedly installed on both sides of the base 100. A lifting plate 303 is movably inserted into the support member 304. Push plates 305 are fixedly installed at both ends of the lifting plate 303. Slide rods 306 are fixedly installed at both ends of the base 100. The push plates 305 are movably sleeved on the slide rods 306. Top rods 307 are fixedly installed at both ends of the side base plate 103. The top rods 307 are aligned with the push plates 305. In this configuration, the lifting plate 303 is composed of multiple right-angled trapezoids, and each right-angled trapezoid corresponds to the support column 301. When the lifting plate 303 moves, the support column 301 is raised or lowered by changing the contact position between the support column 301 and the lifting plate 303.

[0053] like Figures 13 to 15 As shown, further, it also includes a welding unit, which includes a sliding mechanism fixedly installed on one of the fixed plates 223. A stopper 402 is installed on the sliding mechanism. A rotating plate 403 is rotatably connected to one side of the stopper 402. A welding torch 409 is rotatably installed at one end of the rotating plate 403. A rotating rod 404 is fixedly installed at the other end of the rotating plate 403. A pull plate 405 is rotatably connected to the rotating rod 404. A roller 406 is rotatably installed at one end of the pull plate 405. An mounting plate 407 is installed on the sliding mechanism. A guide groove 408 is opened on the mounting plate 407. The roller 406 is movably connected in the guide groove 408. An air tank 410 is installed on the top of the fixing member 216. The air tank 410 is connected to the welding torch 409. In this configuration, the sliding mechanism includes an electric slide rail 400 and an electric slide table 401. The electric slide rail 400 is fixedly connected to the fixed plate 223, the electric slide table 401 is fixedly connected to the stop member 402, the mounting plate 407 is fixedly connected to the electric slide rail 400, and the middle part of the guide groove 408 is V-shaped so that the roller 406 will deflect when it moves. The two ends of the V-shape are located between the two sides of the support column so that the welding torch 409 is already in the rising state when it moves to the edge of the support column.

[0054] like Figure 1 , Figure 4 As shown, the moving mechanism further includes a first gear 104 rotatably mounted on the bottom of the side base plate 103. A power source 105 is mounted on one side of the side base plate 103, and the output end of the power source 105 is connected to the first gear 104. The moving mechanism also includes a toothed groove 101 formed on the base 100, and the first gear 104 meshes with the toothed groove 101. In this configuration, the power source 105 is an electric motor. When it rotates, it drives the first gear 104 to rotate, causing it to roll on the toothed groove 101.

[0055] The implementation principle of a welding device for electric iron accessories in this embodiment is as follows: When welding cable brackets, multiple cable bracket supports are placed on the base 100, and multiple cross arms are placed in the storage bin 102. The power source 105 is started, and the power source 105 drives the first gear 104 to rotate. The first gear 104 drives the side plate 103 to move by meshing with the tooth groove 101.

[0056] During the movement of the side base plate 103, the guide wheel 308 is driven to move via the slide rail 214 and the connecting frame 309. During the movement, the guide wheel 308 contacts the guide plate 300. When the guide wheel 308 moves along the inclined part of the guide plate 300, the guide wheel 308 begins to move to both sides. During the movement, the first slider 213 is driven to move via the connecting frame 309 and the pull rod 310. During the movement, the first slider 213 drives the lower plate 211 to move. During the movement, the lower plate 211 abuts against the outer tube 208. After being abutted by the lower plate 211, the outer tube 208 moves and drives the rotating column 203 to rotate. The rotating column 203 drives the second gear 201 to rotate via the connecting shaft 202. The second gear 201 drives the support platform 204 to move by meshing with the rack 200. The support platform 204 drives the connecting plate 220 to move. The connecting plate 220 drives the push rod 221 to move, so that the cross arm inside the storage bin 102 is pushed out.

[0057] Three elastic elements are provided, consisting of an outer tube 208, an inner tube 209, and a first spring 210. When the rotating column 203 rotates, the three elastic elements rotate with it. When the outer tube 208, which is in contact with the lower plate 211, moves to the guide groove 205, the elastic element descends into the guide groove 205 as a whole. At the same time, the other two elastic elements slide in the guide groove 205, and one of the elastic elements slides along the inclined surface 206. Because the top of the rotating column 203 is blocked by the lower plate 211, the elastic element is compressed when it rises along the inclined surface 206. When the lower plate 211 is reset, the elastic element extends and resets because it loses the blocking effect of the lower plate 211, so that part of the outer tube 208 protrudes from the top of the rotating column 203. At the same time, the upper plate 212 can prevent the elastic element from popping out under the elastic action of the first spring 210 when it is reset.

[0058] When the cross arm is pushed out, it falls onto the support column under the action of the stop 402. When the lower plate 211 moves to the maximum distance on both sides, the power source 105 stops working. At this time, the welding gun 409 performs spot welding to fix the cross arm and the column so that the subsequent workers can perform full welding. After the spot welding is completed, the electric slide table 401 moves to one side and drives the stop 402 to move during the movement so that the stop 402 is misaligned with the welded cross arm. At the same time, the stop 402 drives the roller 406 to move through the rotating rod 404 and the pull plate 405. During the movement, the roller 406 deviates to one side along the guide groove 408 and pulls the rotating rod 404 to rotate through the pull plate 405 so that the welding gun 409 rises and avoids it from colliding with the sides of the support column. When the side plate 103 moves a certain distance and the stop 402 is misaligned with the welded cross arm, the electric slide table 401 drives the stop 402 and the welding gun 409 to reset.

[0059] During the movement of the side base plate 103, the push rod 307 moves. When the side base plate 103 moves to one end of the base 100, the push rod 307 pushes open the push plate 305, and the push plate 305 pulls the lifting plate 303. At this time, the lifting plate 303 moves so that the support column 301 loses its support. The support column 301 drives the guide plate 300 to descend. When the side base plate 103 resets, the guide wheel 308 no longer contacts the guide plate 300. When the side base plate 103 moves to the other end, the push rod 307 pushes open the push plate 305 so that the lifting plate 303 resets. During the reset process, the support column 301 and the guide plate 300 reset. At this time, the guide plate 300 is aligned with the guide wheel 308 again.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
