Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly relates to a positioning welding device for steel grating. Background Art

[0002] Steel grating is a steel product formed by arranging flat steel crosswise at a certain interval and with cross bars, and welded into a square grid in the middle. The steel grating is positioned and welded by a steel grating welding machine. After the flat steel and cross bars arranged according to specifications are positioned on the top of the welding table of the steel grating welding machine, the welding parts moving horizontally on the steel grating welding machine gradually move from above the steel grating components to complete the welding of the flat steel and cross bars. Multiple longitudinal flat steels of the steel grating are operated by workers and clamped between two transverse flat steels at a specified interval. Multiple cross bars are also horizontally placed on the top of the longitudinal flat steels at a specified interval. During the welding process, it is impossible to perform the alignment fastening and spacing adjustment and shaping of the steel components at multiple welding point positions of the steel components. As a result, when the welding parts move down for welding on the semi-finished steel grating, the longitudinal flat steels and cross bars are displaced due to the force at the welding point areas, causing the welding points at the ends of the longitudinal flat steels and the welding points of the cross bars to be misaligned. At the same time, when welding both sides of the steel grating, workers need to flip the steel grating from the side of the semi-finished steel grating, which is likely to cause the flipped semi-finished steel grating to be misaligned, thus making it impossible to conveniently complete the shaping welding operation of the steel grating and affecting the welding efficiency. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning welding device for steel grating. By setting two side positioning seats and two side clamping plates, two pieces of transverse flat steel are positioned on the top of the welding table. A number of splicing area clamping frames rotate towards the inside of the transverse flat steel and clamp the transverse flat steel from the inside. At the same time, the splicing area clamping frames are close to the longitudinal flat steel from the ends of the longitudinal flat steel, and the splicing and positioning and arrangement fastening operations of the transverse flat steel and the longitudinal flat steel are carried out from the positions where the welding points are located. The cross bar positioning module flips above the side positioning seat, so that a number of arc-shaped pressing buckles press and position the cross bars from above, and the spacing adjustment and shaping and long-term fastening positioning of the steel components can be effectively carried out at multiple welding point positions of the steel components, so as to effectively carry out the welding operations at each welding point of the steel components. The turning-over module controls the semi-finished steel grating to turn over and adjusts its position to the top of the welding table, so as to conveniently complete the shaping welding operation of the steel grating on the welding table, and solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention provides the following technical solutions: A steel grating positioning and welding device, comprising a welding machine frame and a welding piece sliding on the top of the welding machine frame. A welding table is fixedly connected to the top of the welding machine frame. Above the welding table, there are two symmetrically distributed side positioning seats. The inner side wall of the side positioning seat is fixedly connected with a side clamping plate. Inside both of the side positioning seats, there is a longitudinal flat steel alignment module. The longitudinal flat steel alignment module includes a rotating frame and a plurality of splicing area clamping frames. The plurality of splicing area clamping frames rotate inside the side positioning seat through the rotating frame. Above the side positioning seat, there is a cross bar positioning module. The cross bar positioning module includes a flipping seat, a combined clamping plate, a connecting beam, and an arc-shaped pressing buckle. The combined clamping plate rotates on the top of the side positioning seat through the flipping seat and a plurality of the connecting beams. The bottom of the connecting beam is fixedly connected with a plurality of the arc-shaped pressing buckles. In front of the side positioning seat, there is a turning-over module. The turning-over module includes a transverse moving seat, a turning-over block, and a connecting plate. The turning-over block fixes the front ends of the two side positioning seats through the connecting plate. The turning-over block rotates inside the transverse moving seat. The transverse moving seat is slidably connected to the top of the welding machine frame.

[0005] Further, the rotating frame is rotatably connected to the top of the side positioning seat. A plurality of the splicing area clamping frames are linearly and equidistantly fixedly connected to the bottom of the rotating frame.

[0006] Further, a clamping head is fixedly connected to the bottom of the splicing area clamping frame. The clamping head is snap-fitted to the bottom of the corresponding side positioning seat.

[0007] Further, the flipping seat is rotatably connected to the top of the side positioning seat. The flipping seat is located behind the corresponding rotating frame.

[0008] Further, a plurality of the connecting beams are linearly and equidistantly fixedly connected to the free end of the flipping seat. The other end of the connecting beam is fixedly connected to the combined clamping plate. The connecting beam is located directly above the corresponding splicing area clamping frame.

[0009] Further, the combined clamping plate corresponds to the other side positioning seat. The combined clamping plate is snap-fitted to the top of the other side positioning seat.

[0010] Further, the turning-over block is fixedly connected to the top of the connecting plate. The connecting plate aligns the two side positioning seats. The two ends of the connecting plate are respectively fixedly connected to the front ends of the two side positioning seats.

[0011] Further, the two ends of the turning-over block are respectively rotatably connected to the corresponding side walls of the transverse moving seat. The rotation center of the turning-over block is at the middle position of the distance between the top of the welding table and the top of the combined clamping plate.

[0012] Further, both the flipping block and the connecting plate are located on the top of the welding table, and the welding table is located inside the transverse moving seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, two side positioning seats and two side clamping plates are provided to position two pieces of transverse flat steel on the top of the welding table. The rotating frames on the two side positioning seats control a plurality of splicing area clamping frames to rotate towards the inside of the transverse flat steel, clamping the transverse flat steel from the inside, and at the same time, the splicing area clamping frames are attached to the longitudinal flat steel from the end of the longitudinal flat steel, so that the splicing positioning and arrangement fastening operations of the transverse flat steel and the longitudinal flat steel can be carried out from the position where the welding point is located. The cross-bar positioning module flips above the side positioning seat, so that a plurality of connecting beams drive a plurality of arc-shaped buckles at the bottom to press and position the cross-bar from above, and the spacing adjustment and long-term fastening positioning of the steel members can be effectively carried out from multiple welding point positions of the steel members, so as to effectively carry out the welding operations at each welding point of the steel members.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Regarding the specific mechanical structure of the present invention, it will be clearly presented in the following detailed description of the structure. The structural content mentioned in the following embodiments is all referenced to the accompanying drawings of the specification. Figures 1 to 6 The structural content mentioned in the following embodiments is all referenced to the accompanying drawings of the specification.

[0017] Please refer to Figures 1 - 6 , in the embodiment of the present invention, a positioning welding device for steel grating includes a welding machine frame 1 and a welding member 11 sliding on the top of the welding machine frame 1. A welding table 12 is fixedly connected to the top of the welding machine frame 1. There are two symmetrically distributed side positioning seats 2 above the welding table 12. A side clamping plate 21 is fixedly connected to the inner side wall of the side positioning seat 2. A longitudinal flat steel alignment module 3 is provided inside both side positioning seats 2. The longitudinal flat steel alignment module 3 includes a rotating frame 31 and a plurality of splicing area clamping frames 32. The plurality of splicing area clamping frames 32 are rotated inside the side positioning seat 2 through the rotating frame 31. A cross bar positioning module 4 is provided above the side positioning seat 2. The cross bar positioning module 4 includes a flipping seat 41, a combined clamping plate 42, a connecting beam 43, and an arc-shaped pressing buckle 44. The combined clamping plate 42 is rotated on the top of the side positioning seat 2 through the flipping seat 41 and a plurality of connecting beams 43. A plurality of arc-shaped pressing buckles 44 are fixedly connected to the bottom of the connecting beam 43. A turning-over module 5 is provided in front of the side positioning seat 2. The turning-over module 5 includes a transverse moving seat 51, a turning-over block 52, and a connecting plate 53. The turning-over block 52 fixes the front ends of the two side positioning seats 2 through the connecting plate 53. The turning-over block 52 is rotated inside the transverse moving seat 51. The transverse moving seat 51 is slidably connected to the top of the welding machine frame 1.

[0018] The welding machine frame 1 serves as a base for connecting the welding member 11 and the welding table 12. The welding table 12 is fixed on the top of the welding machine frame 1. The welding table 12 is used to support the steel grating components. The transverse flat steel and the longitudinal flat steel are sequentially placed on the top of the welding table 12, positioned and adjusted to be shaped, and then welded by the welding member 11. The welding member 11 is connected to the top of the welding machine frame 1 through a movable seat at the bottom, so that the welding member 11 can move horizontally along the side of the welding machine frame 1 on the top of the welding machine frame 1. The welding member 11 moves and descends above the welding table 12 to weld each welding point of the steel grating components.

[0019] The two side positioning seats 2 are symmetrically arranged above the welding table 12. The inner sides of the two side positioning seats 2 are provided with side clamps 21. The side clamps 21 are fixed on the inner side walls of the side positioning seats 2 to stably position the side clamps 21 above the welding table 12. The side clamps 21 can clamp the transverse flat steel from the outside to play the role of positioning the two transverse flat steel from the outside. The flip module 5 is arranged in the front position of the side positioning seat 2. The flip module 5 is composed of a transverse seat 51, a flip block 52 and a connecting plate 53. The flip block 52 is fixedly connected to the top of the connecting plate 53. The connecting plate 53 is aligned with the two side positioning seats 2. The two ends of the connecting plate 53 are respectively fixedly connected to the front ends of the two side positioning seats 2 to stably combine the flip module 5 and the two side positioning seats 2. The flip block 52 is located inside the traverse seat 51, and the two ends of the flip block 52 are rotatably connected to the corresponding side walls of the traverse seat 51, so that the two side positioning seats 2 can be flipped above the welding table 12 through the connecting plate 53 and the flip block 52. The traverse seat 51 is slidably connected to the top of the welding frame 1, and the traverse seat 51 can move laterally along the side of the welding frame 1 at the top of the welding frame 1 through the movable seat at the bottom, so that the flipped side positioning seat 2 can move laterally on the top of the welding table 12 against the top of the welding table 12, effectively adjusting the position of the side positioning seat 2 above the welding table 12, so that the flipped side positioning seat 2 can still move and be positioned on the top of the welding table 12. The flip block 52 and the connecting plate 53 are both located at the top of the welding table 12, and the welding table 12 is located inside the lateral displacement seat 51, so that when the lateral displacement seat 51 moves on the top of the welding machine frame 1, it can stagger the welding table 12 to ensure that the lateral displacement seat 51 can smoothly move the position of the side positioning seat 2 on the top of the welding table 12. The rotation center of the flip block 52 is located at the middle position of the distance between the top of the welding table 12 and the top of the combined buckle plate 42, so as to effectively control the flipping of the side positioning seat 2 at the bottom of the welding machine frame 1, so that the flipped side positioning seat 2 can remain parallel to the welding table 12.

[0020] Two longitudinal flat steel alignment modules 3 are respectively arranged inside the two side positioning seats 2. The longitudinal flat steel alignment module 3 is composed of a rotating frame 31 and a plurality of splicing area clamping frames 32. The rotating frame 31 is rotatably connected to the top of the side positioning seat 2, and a plurality of splicing area clamping frames 32 are fixedly connected to the bottom of the rotating frame 31 at equal straight-line intervals, so that the plurality of splicing area clamping frames 32 can rotate inside the side positioning seat 2 through the rotating frame 31 to adjust the positions of the plurality of splicing area clamping frames 32. The plurality of splicing area clamping frames 32 can move to the top area of the side positioning seat 2 to expose the side clamping plates 21 inside the side positioning seat 2, so as to align and place the transverse flat steel inside the side clamping plates 21. A clamping head 33 is fixedly connected to the bottom of the splicing area clamping frame 32. When the plurality of splicing area clamping frames 32 rotate towards the inside of the side positioning seat 2, the clamping head 33 will rotate together. After the splicing area clamping frame 32 rotates to a position parallel to the side clamping plate 21, the clamping head 33 is clamped to the bottom of the corresponding side positioning seat 2, which can effectively perform the fastening and positioning operation after the splicing area clamping frame 32 rotates towards the inside of the side positioning seat 2. The splicing area clamping frame 32 is fixed at a specified position inside the side positioning seat 2. The outer wall of the splicing area clamping frame 32 is closely attached to the inner wall of the transverse flat steel. The splicing area clamping frame 32 and the side clamping plate 21 can effectively clamp and fix the transverse flat steel on the top of the welding table 12. The position of the splicing area clamping frame 32 is fixed, and the distance between adjacent splicing area clamping frames 32 is fixed. This distance matches the longitudinal flat steel. While the splicing area clamping frame 32 clamps and fixes the transverse flat steel, the two sides of the splicing area clamping frame 32 are respectively closely attached to the corresponding sides of the corresponding longitudinal flat steel, which can separate and control the distance between adjacent longitudinal flat steels. The splicing area clamping frame 32 is aligned at the splicing corner area of the longitudinal flat steel and the transverse flat steel, which can effectively perform the splicing positioning and fastening operation of the transverse flat steel and the longitudinal flat steel from the position of the welding point, and at the same time effectively arrange a plurality of longitudinal flat steels to form a square grid with a specified size.

[0021] The crossbar positioning module 4 is arranged above the side positioning seat 2. The crossbar positioning module 4 is composed of a flipping seat 41, a combined buckle plate 42, a connecting beam 43 and an arc-shaped pressing buckle 44. A number of connecting beams 43 are fixedly connected in a straight line at equal intervals to the free end of the flipping seat 41. The other end of the connecting beam 43 is fixedly connected to the combined buckle plate 42. A number of arc-shaped pressing buckles 44 are fixedly arranged at the bottom of each connecting beam 43. The flipping seat 41 is rotatably connected to the top of the side positioning seat 2. The flipping seat 41 is located behind the corresponding rotating frame 31, so that the rotation operation of the flipping seat 41 will not be hindered by the rotating frame 31. The flipping seat 41 rotates on the top of the side positioning seat 2, enabling the connecting beam 43 to rotate directly above the corresponding splicing area clamping frame 32, and allowing the connecting beam 43 to bring the corresponding arc-shaped pressing buckle 44 to approach the longitudinal flat steel from above, adjusting the positions of the multiple connecting beams 43 and arc-shaped pressing buckles 44. The combined buckle plate 42 corresponds to the other side positioning seat 2. The rotation of the flipping seat 41 enables the combined buckle plate 42 to approach the corresponding side positioning seat 2, so that the combined buckle plate 42 is clamped tightly on the top of the other side positioning seat 2 from above, effectively fixing the crossbar positioning module 4 on the top of the side positioning seat 2. The connecting beam 43 is positioned on the top of a plurality of longitudinal flat steels, so that a number of arc-shaped pressing buckles 44 at the bottom press and position the corresponding crossbars from above, effectively positioning and fastening a plurality of crossbars on the top of the longitudinal flat steels.

[0022] Two side positioning seats 2 and two side clamping plates 21 positioned above the welding table 12 position two transverse flat steels on the top of the welding table 12. Two longitudinal flat steel alignment modules 3 turn inwards inside the two side positioning seats 2, so that a plurality of splicing area clamping frames 32 clamp the transverse flat steel from the inside of the transverse flat steel. At the same time, both sides of the splicing area clamping frame 32 are respectively in close contact with the corresponding longitudinal flat steels, so as to effectively align and fasten the transverse flat steel and the longitudinal flat steel. The cross bar positioning module 4 turns above the side positioning seat 2 to approach the cross bar at the top of the longitudinal flat steel. A plurality of connecting beams 43 press and position the cross bar on the top of the longitudinal flat steel from above with several arc-shaped fasteners 44 at the bottom, and can effectively carry out the alignment, fastening and spacing adjustment and shaping of the steel members from the positions of multiple welding points of the steel members during the welding process. The hollow areas on the longitudinal flat steel alignment module 3 and the cross bar positioning module 4 are staggered from the welding points of each part of the steel member, so as to avoid the dislocation of the end welding points of the longitudinal flat steel and the welding points of the cross bar during welding, and effectively carry out the welding operation of the welding points of each part of the steel member. The welded part 11 moves horizontally above the welding table 12 to batch-weld the top surface of the shaped steel grating. The semi-finished steel grating that has completed the top surface welding operation remains fastened inside the longitudinal flat steel alignment module 3 and the cross bar positioning module 4. Under the control of the turning-over module 5, the turning block 52 and the connecting plate 53 drive the longitudinal flat steel alignment module 3, the cross bar positioning module 4 and the semi-finished steel grating to rotate on the top of the welding table 12, and effectively carry out the turning-over operation of the semi-finished steel grating. After turning over, the turning seat 41 and the combined buckle plate 42 are in close contact with the top of the welding table 12. The transverse moving seat 51 drives the turned-over semi-finished steel grating as a whole to be translated to the top of the welding table 12 for welding operation, so that the turned-over semi-finished steel grating will not be misaligned, and the shaped welding operation of the steel grating on the welding table 12 can be conveniently completed, improving the welding effect and welding efficiency of the steel grating.

[0023] The working principle of the present invention is as follows: Two pieces of horizontal flat steel are respectively clamped inside the two side clamping plates 21 to position the two pieces of horizontal flat steel on the top of the welding table 12. The two longitudinal flat steel alignment modules 3 respectively turn towards the inside of the two side positioning seats 2. A plurality of splicing area clamping frames 32 rotate to the inside of the horizontal flat steel and clamp the horizontal flat steel from the inside. The two sides of the splicing area clamping frame 32 are respectively in close contact with the corresponding longitudinal flat steel to align and fasten the horizontal flat steel and the longitudinal flat steel. At the same time, a plurality of longitudinal flat steels are arranged to form a specified square grid. The cross-bar positioning module 4 turns above the side positioning seat 2 to approach the cross-bar at the top of the longitudinal flat steel. A plurality of connecting beams 43 drive a plurality of arc-shaped fasteners 44 at the bottom to press and position the cross-bar from above on the top of the longitudinal flat steel. The spacing adjustment and shaping and long-term alignment and fastening of the steel member are completed at multiple welding point positions of the steel member. The welding member 11 moves horizontally above the welding table 12 to batch-weld the top surface of the shaped steel grating. The semi-finished steel grating after the top surface welding operation is rotated on the top of the welding table 12 by the turning block 52 and the connecting plate 53 to turn the semi-finished steel grating over. The transverse moving seat 51 drives the turned-over semi-finished steel grating to move horizontally as a whole to the top of the welding table 12, and the semi-finished steel grating is positioned on the top of the welding table 12 again. The welding member 11 moves again to weld the other side of the semi-finished steel grating.
