Description

Technical Field

[0001] The invention belongs to the technical field of steel truss support reinforcement welding, in particular to a steel truss support reinforcement welding processing device and an operating method thereof. Background Art

[0002] The steel frame support reinforcement is an important component of the steel frame floor deck, which is mainly used to connect the steel frame and the support, and transfer the frame load to the support, and then transfer the load to the foundation through the support; at the same time, the steel truss support reinforcement is composed of three straightened steel bars arranged in a triangle, and is connected by two full-length wavy bent web steel bars by resistance spot welding.

[0003] In the prior art, when welding the lower chord steel bars and the web steel bars of the steel truss support bars, the electrode wheel is used to squeeze the lower chord steel bars and the web steel bars onto the electrode plate, and the welding process is performed by resistance welding. However, the existing welding device has the following problems: First, the existing electrode wheel and the electrode plate are both made of copper, which has insufficient strength. However, when squeezed for a long time, a concave part will appear at the squeezed position, which affects the subsequent welding quality. The squeezed position of the electrode wheel and the electrode plate needs to be replaced to continuously ensure the welding quality, but the position replacement is often not timely enough; Second, when the electrode wheel and the electrode plate are squeezed, the electrode wheel is generally The lower chord steel bars are pushed to move, fit on the web bars, and then squeezed on the electrode plate. However, during welding, the web bars are generally welded on the upper chord steel bars first. Because the cross-section of the steel truss support bars is an isosceles triangle, after the web bars are welded on the upper chord steel bars, the web bars will be warped outward and the distance will be uncertain. When the web bars and the lower chord steel bars are welded, the electrode plate is in a fixed state. The lower chord steel bars and the web bars are only pushed by the electrode wheel to fit and squeeze on the electrode plate, which may easily lead to the web bars and the lower chord steel bars not fitting tightly enough, and will also greatly affect the welding quality, resulting in welding failure or fracture of the weld in the later stage.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 12As shown, a steel truss support rib welding processing device according to an embodiment of the present invention comprises a pair of bases 1 and a pair of guide wheels 11; the pair of bases 1 are symmetrically arranged and staggered with the pair of guide wheels 11; a fixed plate 17 is fixedly connected to the middle of the base 1; first circular grooves 18 are provided on both side walls of the fixed plate 17; a copper plate 19 slides in the first circular groove 18; the cross section of the copper plate 19 is an isosceles trapezoid; a pair of first slide grooves 13 symmetrically distributed about the fixed plate 17 are provided on the base 1; an inclined plate is slidably connected in the first slide groove 13 12; A pair of cylinders 14 symmetrically distributed about a fixed plate 17 are fixedly connected to the base 1, and the output end of the cylinder 14 is fixedly connected to the inclined plate 12; a copper wheel 15 is provided on the side wall of the end of the inclined plate 12, and a servo motor 16 is provided on the other side of the inclined plate 12, and the copper wheel 15 is rotated by the servo motor 16; the servo motor 16 is started by a starting member; the copper disk 19 and the copper wheel 15 move toward each other through an extrusion member; the copper disk 19 is rotated by a rotating member; in the prior art, when welding the lower chord steel bars and the web steel bars of the steel truss support reinforcement, a The electrode wheel squeezes the lower chord steel bar and the web steel bar onto the electrode plate, and then welds them by resistance welding. However, the existing welding device has the following problems: First, the existing electrode wheel and electrode plate are both made of copper, which is not strong enough. However, when squeezed for a long time, a concave part will appear at the squeezed position, which will affect the subsequent welding quality. The squeezed position of the electrode wheel and the electrode plate needs to be replaced to continuously ensure the welding quality, but the position replacement is often not timely enough. Second, when the electrode wheel and the electrode plate are squeezed, the electrode wheel generally pushes the lower chord steel bar to move and fits on the web steel bar. However, during welding, the web reinforcement is usually welded to the upper chord reinforcement first. Since the cross-section of the steel truss support bar is an isosceles triangle, after the web reinforcement is welded to the upper chord reinforcement, the web reinforcement will be warped outwards and the distance will be uncertain. When the web reinforcement and the lower chord reinforcement are welded, since the electrode plate is in a fixed state, the electrode wheel is used to push the lower chord reinforcement and the web reinforcement to fit and squeeze the electrode plate, which may cause the web reinforcement and the lower chord reinforcement to fit not tightly enough, and greatly affect the welding quality, resulting in the welding failure or fracture of the welding part in the later stage.Therefore, when the present invention is working, its copper wheel 15 and copper plate 19 are both one side of the electrode. This is the prior art and will not be elaborated. At the same time, the above is a welding device for the web bar and the lower chord steel bar in the forming process of the entire steel truss support bar. The remaining traction devices, bending devices, etc. are not drawn (prior art). When the web bar and the lower chord steel bar are welded, a pair of bases 1 are provided, and the adjacent welding points of the web bar and the lower chord steel bar are welded by the copper plate 19 and copper wheel 15 on the pair of bases 1. During welding, the inclined plate 12 is pushed to move by the cylinder 14, thereby driving the copper wheel 15 to move. When the copper wheel 15 moves, the copper plate 19 will be driven by the extrusion piece to move toward the copper wheel 15. The copper wheel 15 and the copper plate 19 move toward each other, allowing them to move. The web bar steel bar is basically in a fixed position, so that the web bar steel bar and the lower chord steel bar are welded and processed in a tight state to ensure the welding quality. At the same time, after the copper wheel 15 and the copper plate 19 are welded, the copper wheel 15 will drive the servo motor 16 to work through the starting part to drive the copper wheel 15 to rotate. At the same time, the copper plate 19 will also rotate through the rotating part to adjust the extrusion position of the copper wheel 15 and the copper plate 19 to avoid the extrusion position being always in a certain place, so that the copper plate 19 and the copper wheel 15 are in a uniform extrusion state. In the later stage, it is only necessary to adjust the pushing distance of the cylinder 14 according to the overall state of the extrusion concave to ensure the welding quality, avoid the untimely replacement of the position of the electrode wheel and the electrode plate, and also avoid the position adjustment operation, which affects the overall welding efficiency. ;

[0037] The extrusion member includes a fixed box 2; a pair of symmetrically distributed fixed boxes 2 are fixedly connected to the base 1; a moving shaft 25 is rotatably connected to the middle of the copper plate 19; a pair of first through holes 27 are opened on the side wall of the fixed box 2; the moving shaft 25 passes through the first through hole 27; a group of teeth 26 are fixedly connected to the outer wall of the moving shaft 25; an L-shaped rack 24 is fixedly connected to the side wall of the inclined plate 12, and the horizontal rod of the L-shaped rack 24 passes through the fixed box 2; a first rotating shaft 21 is rotatably connected in the fixed box 2, and a first gear 22 and a second gear 23 are fixedly connected to the first rotating shaft 21; the first gear 22 and a group of teeth 26 on the moving shaft 25 are meshed with each other; the second gear 23 and the horizontal rod of the L-shaped rack 24 are meshed with each other; the horizontal rod of the L-shaped rack 24 and the teeth 26 of the moving shaft 25 are located on both sides of the first rotating shaft 21; the inner diameter of the first gear 22 is smaller than the inner diameter of the second gear 23; the moving shaft 25 A guide plate 45 is fixedly connected to it; a guide groove 46 is provided on the inner wall of the first through hole 27; the guide plate 45 is slidably connected in the guide groove 46; during operation, when the inclined plate 12 is pushed by the cylinder 14 and then drives the copper wheel 15 to move, at this time, the horizontal rod of the L-shaped rack 24 and the second gear 23 are meshed with each other, thereby driving the first rotating shaft 21 to rotate. When the first rotating shaft 21 rotates, the first gear 22 and the teeth 26 on the moving shaft 25 are meshed, thereby driving the moving shaft 25 to move horizontally, thereby driving the copper wheel 15 and the copper disk 19 to move toward each other. At the same time, the inner diameter of the first gear 22 is smaller than the inner diameter of the second gear 23, in order to facilitate the movement and placement of the lower chord steel bars and the web steel bars, and to ensure that the movement and welding of the lower chord steel bars and the web steel bars are not affected in a limited space (the parts on the above-mentioned copper wheel 15 and copper disk 19 and the copper wheel 15 or copper disk 19 have a shielding layer, which will not affect the resistance welding between the two, and the following parts are the same).

[0038] The rotating member includes a disc 32; a disc 32 is fixedly connected to the side wall of the copper disc 19 near the bottom of the first circular groove 18; a pair of first grooves 33 are opened on the outer wall of the disc 32; a fixing column 34 is fixedly connected to the bottom of the first groove 33 through a spring; a group of second slide grooves 3 and a group of arc-shaped inclined grooves 31 are opened on the inner ring wall of the first circular groove 18; a plurality of arc-shaped inclined grooves 31 are located between adjacent second slide grooves 3; the bottom of the second slide groove 3 is a stepped surface, and the step of the stepped surface is inclined; the depth of one end of the arc-shaped inclined groove 31 is higher than the high surface of the step surface of the second slide groove 3, and the depth of the other end of the arc-shaped inclined groove 31 is the same as the low surface of the step surface, and the end side wall of the arc-shaped inclined groove 31 is connected with the inclined surface of the step of the step surface; the fixing column 34 slides in the second slide groove 3 and the arc-shaped inclined groove 31; during operation, when the copper plate 19 and the copper wheel 15 are moving toward each other, the fixed column 34 will move with the second slide groove 3, and the fixed column 34 will move from the high surface of the step surface to the low surface. At this time, the depth of one end of the arc-shaped inclined groove 31 is higher than the high surface of the step surface of the second slide groove 3. Therefore, the copper plate 19 can be moved out horizontally at this time. When the copper plate 19 and the copper wheel 15 move in the opposite direction, the fixed column 34 will be blocked by the stepped inclined surface of the step surface when it moves in the opposite direction, allowing the fixed column 34 to enter the arc-shaped inclined groove 31, and then allowing the fixed column 34 to enter the adjacent second slide groove 3, thereby driving the rotation adjustment of the copper plate 19, and repeating the cycle so that the copper plate 19 is in a uniform rotation state to ensure uniform adjustment of the extrusion position.

[0039] The starting member includes an elastic plate 37; an elastic plate 37 is fixedly connected to the side wall of the first slide groove 13 through a spring, and a negative plate 36 is fixedly connected to the elastic plate 37; a positive plate 35 is fixedly connected to the side wall of the inclined plate 12 located in the first slide groove 13; when the positive plate 35 and the negative plate 36 are in contact with each other, the servo motor 16 works; during operation, when the cylinder 14 contracts, the inclined plate 12 moves, which allows the negative plate 36 and the positive plate 35 to contact each other, allowing the servo motor 16 to work, and then allowing the copper wheel 15 to be at a fixed rotation angle (the servo motor 16 has a locking mechanism, which is a prior art) to adjust the extrusion position of the copper wheel 15.

[0040] The inclined plate 12 is provided with a first through slot 4; a first slider 41 is slidably connected in the first through slot 4; the servo motor 16 is fixedly connected to one side of the first slider 41, and the copper wheel 15 is rotatably connected to the first slider 41 through a rotating shaft, and the output end of the servo motor 16 and the rotating shaft are connected to each other; a first threaded column 42 is rotatably connected in the first through slot 4, the first threaded column 42 and the first slider 41 are threadedly connected, and the end of the first threaded column 42 extends out of the inclined plate 12; the first slider 41 is square; when working, the first threaded column 42 can drive the first slider 41 to move back and forth in the first through slot 4, and then the overall position of the copper wheel 15 can be fine-tuned to ensure the accuracy of the welding position.

[0042] A pair of symmetrically distributed second grooves 5 are provided on the side walls on both sides of the fixed plate 17; an L-shaped rod 51 is slidably connected in the second groove 5, and the end of the L-shaped rod 51 is fixedly connected to the bottom of the second groove 5 by a spring, and the end rod of the L-shaped rod 51 is inclined, and the vertical rod of the L-shaped rod 51 and the inclined surface on the outer wall of the copper plate 19 are parallel to each other; a third groove 52 is provided on the end of the vertical rod of the L-shaped rod 51; a cleaning plate 53 is fixedly connected to the bottom of the third groove 52 by a spring; a fourth groove 54 is provided in the middle of the side wall of the cleaning plate 53 extending out of the third groove 52; an isosceles triangle block 55 is provided in the middle of the side wall of the cleaning plate 53; the isosceles triangle block 55 is provided on the side wall It is fixed to the bottom of the fourth groove 54 by a spring; two groups of first cleaning brushes 56 about the isosceles triangle block 55 are fixed to the side wall of the cleaning plate 53; the cleaning plate 53 circulates up and down through the power part; during operation, when the lower chord steel bars and the web steel bars are welded, welding slag will be left on the surface of the electrode plate. In order to avoid the influence of welding slag on subsequent welding, when the copper disk 19 rotates, the cleaning plate 53 on the L-shaped rod 51 will scrape and clean the surface of the copper disk 19 (isosceles triangle block 55 and the first cleaning brush 56), and at the same time, one end of the L-shaped rod 51 is fixed to the bottom of the second groove 5 by a spring, so that the cleaning plate 53 can move with the copper disk 19 to ensure the cleaning fit.

The copper wheel 15 and the copper plate 19 move toward each other, so that the web reinforcement is basically in a fixed position, and the welding of the web reinforcement and the lower chord reinforcement is tightly bonded.

[0047] S2: After the copper wheel 15 and the copper plate 19 are welded, the copper wheel 15 drives the servo motor 16 to work through the starter, driving the copper wheel 15 to rotate. At the same time, the copper plate 19 also rotates through the rotating part to adjust the extrusion position of the copper wheel 15 and the copper plate 19.

[0048] Working principle: When the web reinforcement and the lower chord reinforcement are welded, a pair of bases 1 are provided, and the adjacent welding points of the web reinforcement and the lower chord reinforcement are welded by the copper disc 19 and the copper wheel 15 on the pair of bases 1. During welding, the inclined plate 12 is pushed to move by the cylinder 14, thereby driving the copper wheel 15 to move. When the copper wheel 15 moves, the copper disc 19 is driven to move toward the copper wheel 15 through the extrusion piece. The copper wheel 15 and the copper disc 19 move toward each other, so that the web reinforcement is basically in a fixed position, so that the welding of the web reinforcement and the lower chord reinforcement is tightly fitted, ensuring the welding quality. At the same time, after the copper wheel 15 and the copper plate 19 are welded, the copper wheel 15 will drive the servo motor 16 to work through the starting part, drive the copper wheel 15 to rotate, and the copper plate 19 will also rotate through the rotating part to adjust the extrusion position of the copper wheel 15 and the copper plate 19 to avoid the extrusion position being always in a certain place, so that the copper plate 19 and the copper wheel 15 are in a uniform extrusion state. In the later stage, it is only necessary to adjust the pushing distance of the cylinder 14 according to the overall state of the extrusion concave to ensure the welding quality, avoid the untimely replacement of the position of the electrode wheel and the electrode plate, and also avoid the position adjustment operation, which affects the overall welding Efficiency; when the copper plate 19 and the copper wheel 15 are moving towards each other, the fixed column 34 will move with the second chute 3. At this time, the fixed column 34 moves from the high surface of the step surface to the low surface. Therefore, the depth of one end of the arc-shaped inclined groove 31 is higher than the high surface of the step surface of the second chute 3. Therefore, the copper plate 19 can be moved out horizontally at this time. When the copper plate 19 and the copper wheel 15 move in the opposite direction, the fixed column 34 will be blocked by the stepped inclined surface when it moves in the opposite direction, allowing the fixed column 34 to enter the arc-shaped inclined groove 31, and then allow the fixed column 34 to enter the adjacent second chute 3, thereby driving the copper plate 19 The rotation adjustment is repeated in a cycle to keep the copper disk 19 in a uniform rotation state to ensure uniform adjustment of the extrusion position; when the lower chord steel bars and the web steel bars are welded, welding slag will be left on the surface of the electrode plate. In order to avoid the influence of welding slag on subsequent welding, when the copper disk 19 rotates, the cleaning plate 53 on the L-shaped rod 51 will scrape and clean the surface of the copper disk 19 (isosceles triangle block 55 and the first cleaning brush 56). At the same time, one end of the L-shaped rod 51 is fixed to the bottom of the second groove 5 through a spring, so that the cleaning plate 53 can move with the copper disk 19 to ensure cleaning fit.
