When the steel grating is automatically welded, the welding base 1 serves as the supporting structure of the automatic welding equipment for the steel grating. The fixing frame 12 at the top of the support block 11 is fixed to the limiting plate 13 and is used as an operating table for welding the steel grating. First, multiple flat steels are placed in multiple limiting grooves 15 respectively, and guided by the arc-shaped surface of the limiting groove 15. The guide assembly assists in placing the flat steels, and the multiple flat steels are quickly inserted into the limiting plates 13 accordingly. The feeding mechanism is used to stagger the cross bars on the grooves of the multiple flat steels. Finally, the welding assembly is used to weld the staggered flat steels and cross bars, which replaces the traditional way of placing the steel grating raw materials, speeds up the feeding arrangement, and thus improves the efficiency of automatic welding of the steel grating.

[0029] The guide assembly includes a rotating rod 2 and a clamping plate 21; multiple rotating rods 2 are connected to the outside of the limit plate 13 through a torsion spring, and the rotating rod 2 is located at the limit groove 15; the clamping plate 21 is fixed to the outside of the rotating rod 2; when multiple flat steels are placed for welding, the flat steels are placed correspondingly at multiple limit grooves 15. At this time, the clamping plate 21 is supported by the torsion spring on the rotating rod 2 and guided by the arc on one side of the limit groove 15 to quickly tilt the flat steel and place it on the top surface of the clamping plate 21. Finally, it is pressed into the limit groove 15. The clamping plate 21 rotates with the rotating rod 2, and the torsion spring is driven by force to drive the clamping plate 21 to squeeze the flat steel against the outer wall of the limit plate 13, which plays a role in quickly placing and limiting the flat steel, making it convenient for rapid welding of the steel grating.

[0030] like Figure 1 and Figure 3 As shown, the welding assembly includes a support frame 3, an electric cylinder 31, a connecting plate 32, a fixing seat 33, a welding machine 34 and a welding head 35; the support frame 3 is fixed to the top of the welding base 1; the electric cylinder 31 is fixed to the outside of the support frame 3; the connecting plate 32 is fixed to the output end of the electric cylinder 31; the fixing seat 33 is slidably connected to the bottom end of the connecting plate 32 through an electric slider No. 1; the welding machine 34 is fixed to the bottom end of the fixing seat 33; a plurality of welding heads 35 are fixed to the bottom end of the welding machine 34; when the steel grid is welded, the welding machine 34 is welded to the bottom end of the welding base 1. When the plate is automatically welded, the flat steel and cross bar are first placed on the limit plate 13 and arranged neatly. Then the output end of the electric cylinder 31 supported by the support frame 3 extends downward, driving the fixed seat 33 at the bottom end of the connecting plate 32 to move downward. The No. 1 electric slider drives the welding machine 34 at the bottom end of the fixed seat 33 close to the welding point. When it reaches the welding point of the flat steel and the cross bar, the output end of the electric cylinder 31 and the No. 1 electric slider continuously cooperate to lift and slide, thereby driving multiple welding heads 35 to weld the intersection of the flat steel and the cross bar, thereby playing the role of automatic welding of the steel grating.

[0031] like Figure 1 、 Figure 4 and Figure 5As shown, a chute 4 is provided at the top of the fixing frame 12; the discharge mechanism includes a No. 2 electric slider 41, a short plate 42, a crossbar box 43 and a matching component; the No. 2 electric slider 41 is slidably connected to the chute 4 at the top of the fixing frame 12; the short plate 42 is fixed to the outside of the No. 2 electric slider 41; the crossbar box 43 is fixed to the outside of the end of the short plate 42 away from the No. 2 electric slider 41; the matching component is arranged on the outside of the fixing frame 12, and the matching component is used to assist in the crossbar blanking; when the crossbar is discharged and welded, First, place multiple cross bars inside the cross bar box 43. After multiple flat steels are placed, the No. 2 electric slider 41 slides in the slide groove 4. The No. 2 electric slider 41 drives the cross bar box 43 connected to the short plate 42 to slide synchronously. Relying on the matching components, during the sliding process of the No. 2 electric slider 41, the multiple cross bars inside the cross bar box 43 are sequentially cut into the corresponding grooves of multiple flat steels, thereby realizing the staggered arrangement of multiple flat steels and cross bars, facilitating the rapid welding of the steel grating, and thereby improving the automatic welding efficiency of the steel grating.

[0032] The mating components include a track plate 5, a rotating roller 51 and a roller 53; the two track plates 5 are correspondingly fixed to the outside of the fixed frame 12; the rotating roller 51 is rotatably connected to the inner wall of the cross bar box 43; a plurality of material troughs 52 are opened on the outside of the rotating roller 51; the two rollers 53 are respectively fixed to the two ends of the rotating roller 51; when the cross bars inside the cross bar box 43 are discharged and welded, the two rollers 53 are used to support the rotating roller 51, and the No. 2 electric slider 41 drives the cross bar box 43 to slide and move, and the roller 53 will roll at the track plate 5. The multiple cross bars in the cross bar box 43 can enter the material trough 52 in turn. As the rotating roller 51 rotates, the cross bars in the material trough 52 fall when they reach the bottom position, and the cross bars can fall into the corresponding grooves of multiple flat steels, thereby realizing the intermittent discharge of the cross bars, which is convenient for the subsequent rapid welding of the steel grating.

[0033] A stop block 6 is fixed to the interior of the cross bar box 43; the stop block 6 is located above the rotating roller 51; the gap between the stop block 6 and the inner wall of the cross bar box 43 corresponds to the material trough 52; when the multiple cross bars inside the cross bar box 43 are intermittently discharged, the stop block 6 is fixed to the inside of the cross bar box 43, and the stop block 6 can guide the multiple cross bars to be arranged, so that the cross bars above the stop block 6 can be stacked in multiple rows, and the gap between the stop block 6 and the inner wall of the cross bar box 43 can stack a row of cross bars, and during the rotation of the rotating roller 51, one cross bar is lowered into the inside of the material trough 52 in turn, thereby improving the discharge effect of the cross bars.

[0034] like Figure 1 and Figure 3As shown, the outside of the welding machine 34 is fixedly connected to a fixed plate 7; the inner wall of the fixed plate 7 is slidably connected to a sliding rod 71; the bottom end of the sliding rod 71 is fixedly connected to a No. 1 extrusion plate 72; the outside of the sliding rod 71 is sleeved with an elastic member 73, and the elastic member 73 is located between the fixed plate 7 and the No. 1 extrusion plate 72; when the flat steel is placed and welded, some flat steels become uneven after placement, resulting in reduced quality of the welded steel grating. The fixed plate 7 is fixed to the external support sliding rod 71 of the welding machine 34. As the No. 1 electric slider drives the fixed seat 33 to slide, the No. 1 extrusion plate 72 can fit on the multiple flat steels at the next welding position and extrude. Relying on the elastic force of the elastic member 73 and the No. 1 extrusion plate 72 to extrude the next group of flat steels, the flat steels are completely pressed into the limit groove 15, thereby reducing the quality problems of the steel grating after welding.

[0035] A plurality of purifiers 8 are fixedly connected to the top of the fixed seat 33; an exhaust slot is provided on the outside of the No. 1 extrusion plate 72 near the welding head 35; an air duct 81 is fixedly connected to the output end of the plurality of purifiers 8, and the air duct 81 is connected to the exhaust slot of the No. 1 extrusion plate 72; when the steel grating is automatically welded, since the steel grating needs to be welded at multiple intersections of the flat steel and the cross bar, a large amount of smoke will be generated during welding. A plurality of purifiers 8 are fixed to the end of the fixed seat 33, and the air duct 81 is connected to the exhaust slot of the No. 1 extrusion plate 72. The exhaust slot corresponds to the welding head 35. The smoke generated during the welding process is extracted and sent to the interior of the purifier 8 for purification and discharge, thereby reducing the air pollution caused by a large amount of smoke.

[0036] like Figure 1 、 Figure 4 and Figure 5 As shown, the outside of the crossbar box 43 is fixedly connected with a No. 2 extrusion plate 9, and a slope is provided on one side of the No. 2 extrusion plate 9; the No. 2 extrusion plate 9 is located on the side close to the support block 11; when multiple crossbars are placed in the corresponding grooves of multiple flat steels in turn, as the crossbar box 43 moves to lower the multiple crossbars, the No. 2 extrusion plate 9 fixed to the tail of the crossbar box 43 moves accordingly, and the slope of the No. 2 extrusion plate 9 can squeeze the crossbar protruding from the corresponding groove when sliding, and press the crossbar that is not fully stuck in the corresponding groove of the flat steel into the corresponding groove, thereby improving the quality of automatic welding of the steel grating and reducing the unevenness of the steel grating after welding.

[0037] like Figure 1 and Figure 3As shown, four welds are provided at the bottom ends of the multiple welding heads 35; the four welds of the welding heads 35 are respectively located at the four corners of the welding heads 35; when welding the steel grating, four welds are provided at the bottom ends of the multiple welding heads 35, and the four welds are respectively located at the four corners of the welding heads 35, and the four welds correspond to the four corners of the square grid formed by the staggered placement of flat steels and cross bars, so that the multiple welding heads 35 can quickly weld the multiple intersections of the flat steels and cross bars, thereby improving the overall stability of the steel grating after welding.

[0038] Working process: When automatically welding the steel grating, the welding base 1 serves as the supporting structure of the steel grating automatic welding equipment. The fixing frame 12 on the top of the support block 11 is fixed to the limit plate 13 and used as an operating table for welding the steel grating. First, multiple flat steels are placed in multiple limit grooves 15 respectively. Relying on the arc surface guidance of the limit groove 15, the guide assembly assists in placing the flat steels, and quickly inserts multiple flat steels into the limit plate 13. Cooperate with the discharge mechanism to stagger the cross bars on the grooves of multiple flat steels. Finally, the welding assembly is used to weld the staggered flat steels and cross bars, replacing the traditional method of placing the steel grating. The material-laying method speeds up the material discharging and arrangement speed, thereby improving the efficiency of automatic welding of steel gratings; when placing and welding multiple flat steels, the flat steels are placed in multiple limit grooves 15 accordingly. At this time, the clamping plate 21 is supported by the torsion spring on the rotating rod 2 and guided by the arc on one side of the limit groove 15, so that the flat steel is quickly tilted and placed on the top surface of the clamping plate 21, and finally pressed into the limit groove 15. The clamping plate 21 rotates with the rotating rod 2, and the torsion spring is driven by force to drive the clamping plate 21 to squeeze the flat steel on the outer wall of the limit plate 13, which plays a role in quickly placing and limiting the flat steel, and is convenient for rapid welding of steel gratings;

[0039] When the steel grating is welded automatically, the flat steel and the cross bar are first placed on the limit plate 13 and arranged neatly. Then, the output end of the electric cylinder 31 supported by the support frame 3 extends downward, driving the fixing seat 33 at the bottom end of the connecting plate 32 to move downward, and the No. 1 electric slide drives the welding machine 34 at the bottom end of the fixing seat 33 to approach the welding point. When it reaches the welding point of the flat steel and the cross bar, the output end of the electric cylinder 31 and the No. 1 electric slide continuously cooperate with the lifting and sliding displacement to drive multiple welding heads 35 to weld the intersection of the flat steel and the cross bar, thereby playing the role of automatic welding of the steel grating; when welding the steel grating, four welding ports are set at the bottom ends of multiple welding heads 35, and the four welding ports are respectively located at the four corners of the welding heads 35. The four welding ports correspond to the four corners of the square lattice formed by the staggered placement of the flat steel and the cross bar, so that the multiple welding heads 35 can quickly weld the multiple intersections of the flat steel and the cross bar, thereby improving the overall stability of the steel grating after welding;

[0040] When welding the cross bars, multiple cross bars are first placed inside the cross bar box 43. After multiple flat steels are placed, the No. 2 electric slider 41 slides in the slide groove 4, and the No. 2 electric slider 41 drives the cross bar box 43 connected to the short plate 42 to slide synchronously. In the process of sliding the No. 2 electric slider 41, the multiple cross bars inside the cross bar box 43 are sequentially discharged into the corresponding grooves of multiple flat steels by means of the matching components, thereby realizing the staggered arrangement of multiple flat steels and cross bars, facilitating the rapid welding of the steel grating, and thus improving the automatic welding efficiency of the steel grating; when welding the cross bars inside the cross bar box 43, two rollers 53 are used to support the rotating roller 51. In the process of the No. 2 electric slider 41 driving the cross bar box 43 to slide, the rollers 53 will move in the same direction. The track plate 5 rolls, and the multiple cross bars in the cross bar box 43 can enter the material trough 52 in turn. As the rotating roller 51 rotates, the cross bars in the material trough 52 fall down when they reach the bottom position, and the cross bars can fall into the corresponding grooves of the multiple flat steels, thereby realizing the intermittent discharge of the cross bars, which is convenient for the subsequent rapid welding of the steel grating; when the multiple cross bars inside the cross bar box 43 are intermittently discharged, the stop block 6 is fixed to the inside of the cross bar box 43, and the stop block 6 can guide the multiple cross bars to be arranged, so that the cross bars above the stop block 6 can be stacked in multiple rows, and the gap between the stop block 6 and the inner wall of the cross bar box 43 can stack a row of cross bars, and during the rotation of the rotating roller 51, one cross bar is lowered into the inside of the material trough 52 in turn, thereby improving the discharge effect of the cross bars;

[0041] The cam 72 is pressed against the top of the welding machine 34 so that the welding head 34 is smooth and the welding machine 30 is in good condition.

[0042] When multiple cross bars are placed in the corresponding grooves of multiple flat steels in turn, as the cross bar box 43 moves and lowers the multiple cross bars, the No. 2 extrusion plate 9 fixed to the tail of the cross bar box 43 moves accordingly. The inclined surface of the No. 2 extrusion plate 9 can squeeze the cross bars protruding from the corresponding grooves when sliding, and press the cross bars that are not fully stuck in the corresponding grooves of the flat steel into the corresponding grooves, thereby improving the quality of automatic welding of the steel grating and reducing the unevenness of the steel grating after welding.
