The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] First embodiment

[0022] See also Figure 1 to Figure 3 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment, Figure 2 is a front view of the overall structure of the first embodiment, Figure 3 It is a cross-sectional view of the overall internal structure of the first embodiment.

[0023] The utility model provides an automatic welding device for corrugated and ladder bridges: comprising a welding table 101, a fixing frame 102, a welding machine 103 and a fixing assembly, wherein the fixing assembly comprises a support plate 104, two drive motors 105, two cams 106, two clamping plates 107, two extrusion rods 108, a limit spring 109, a limit rod 110 and two rubber pads 111. The above-mentioned solution solves the problem that the existing corrugated and ladder bridges are not fixed on the welding table during welding, the bridges are prone to offset, and the welding quality of the corrugated and ladder bridges is affected.

[0024] According to this specific embodiment, the fixing frame 102 is fixedly connected to the welding table 101 and is located above the welding table 101. The welding machine 103 is arranged on the fixing frame 102. The fixing assembly is arranged on the welding table 101. The bridge is fixed on the welding table 101 by the fixing assembly, and then the welding machine 103 is started to fix the bridge.

[0025] The support plate 104 is fixedly connected to the welding platform 101 and is located below the welding platform 101. The two drive motors 105 are fixedly connected to the support plate 104 and are located above the support plate 104. The two cams 106 are respectively connected to the corresponding drive motors 105. The welding platform 101 has a through slot 112. The two extrusion rods 108 are movably connected to the welding platform 101 and are symmetrically arranged in the through slot 112. Each extrusion rod 108 is symmetrically arranged in the through slot 112. The rods 108 are respectively movably matched with the corresponding cams 106, the two ends of the limit spring 109 are respectively fixedly connected to the two extrusion rods 108, the two clamping plates 107 are respectively fixedly connected to the corresponding extrusion rods 108, and are both located above the welding platform 101. When welding the bridge, the bridge to be welded is first placed in the welding platform 101 and located between the two clamping plates 107, and then the two driving motors 105 on the support plate 104 are started, and the two driving motors 105 are connected to the two driving motors 105. The motor 105 drives the two cams 106 to rotate respectively, so that the short end of the cam 106 gradually leaves the extrusion rod 108, and the long end of the cam 106 squeezes the extrusion rod 108. At this time, the extrusion rod 108 is squeezed by the cam 106, and the two extrusion rods 108 move relatively in the through groove 112. The limit spring 109 is compressed, and the extrusion rod 108 drives the clamping plate 107 to move to the outside of the bridge until the two clamping plates 107 clamp the bridge. The bridge is fixed and then the welding machine 103 on the fixing frame 102 is started to perform welding operation on the bridge. After the welding of the bridge is completed, the driving motor 105 is started to drive the cam 106 to rotate and reset. At this time, the two clamping plates 107 are kept away from the bridge by the force of the limit spring 109, and finally the welded bridge is taken out from the welding table 101. In the above manner, the bridge can be fixed on the welding table 101 to prevent the bridge from shifting, thereby ensuring the welding quality of the bridge.

[0026] Secondly, both ends of the limit rod 110 are fixedly connected to the welding table 101 and are located in the through groove 112, and the limit rod 110 passes through the two extrusion rods 108. By arranging the limit rod 110 in the through groove 112, when the two extrusion rods 108 squeeze the limit spring 109 in the through groove 112, the limit rod 110 can prevent the limit spring 109 from bending outward from the through groove 112.

[0027] At the same time, the two rubber pads 111 are fixedly connected to the corresponding clamps 107 and are respectively located on the outer side walls of the clamps 107. By arranging the rubber pads 111 on each clamp 107, the rubber pads 111 can reduce the friction between the clamps 107 and the bridge frame, so that the bridge frame can be fixed more stably.

[0028] When welding the bridge, the bridge to be welded is first placed in the welding table 101 and located between the two clamping plates 107, and then the two driving motors 105 on the support plate 104 are started, and the two driving motors 105 respectively drive the two cams 106 to rotate, so that the short ends of the cams 106 gradually leave the squeezing rods 108, and the long ends of the cams 106 squeeze the squeezing rods 108. At this time, the squeezing rods 108 will be squeezed by the cams 106, and the two squeezing rods 108 will move relative to each other on the limiting rods 110, and the limiting springs 109 will be compressed, and the squeezing rods 108 will drive the clamping plates 107 to move toward the outside of the bridge until the two clamping plates are connected. The plate 107 clamps the bridge frame and fixes it, and then the welding machine 103 on the fixing frame 102 is started to perform welding operations on the bridge frame; after the welding of the bridge frame is completed, the driving motor 105 is started to drive the cam 106 to rotate and reset, and at this time, the two clamping plates 107 are moved away from the bridge frame by the force of the limit spring 109, and finally the welded bridge frame is taken out from the welding table 101; in addition, by arranging the rubber pad 111 on each of the clamping plates 107, the rubber pad 111 can reduce the friction between the clamping plate 107 and the bridge frame, so that the bridge frame can be fixed more stably. In the above manner, the bridge frame can be fixed on the welding table 101, the bridge frame can be prevented from being offset, and the welding quality of the bridge frame is guaranteed.
