Description

Technical Field

[0001] The present invention relates to the technical field of welding processing, and specifically to a welding processing device for a steel bar truss floor slab. Background Art

[0002] The welding processing device for a steel bar truss floor slab includes the welding of the entire steel bar truss floor slab, mostly the welding between the two. However, during use, the welding during the installation of the steel bar truss floor slab is also essential. By welding stud bolts on the floor slab, the offset of the steel bar truss floor slab caused by pouring concrete can be reduced.

[0003] When the existing stud bolts are welded to the steel bar truss floor slab, in order to protect the arc heat, protect the arc, and assist the molten iron of the weld to form, a ceramic ring is usually used and placed at the welding position of the stud bolt and the floor slab to ensure the welding quality.

[0004] However, it is found in the actual use process that when workers perform stud bolt welding operations, they must carry a large number of ceramic rings with them. During operation, they need to first take out the ceramic rings and place them stably, and then use a welding torch to accurately weld the stud bolts in place. In this process, workers not only need to flexibly control the welding torch, but also have to carry multiple ceramic rings, which undoubtedly increases their movement difficulty. At the same time, after welding is completed, workers need to break the ceramic rings to check whether the welding quality of the stud bolts meets the standard. The traditional method requires carrying a hammer with them and knocking it. This method is likely to cause the offset of the stud bolt position and affect the welding effect. For this reason, we propose a welding processing device for a steel bar truss floor slab. Summary of the Invention

[0005] One technical problem to be solved by this application is that for the traditional welding of stud bolts to a steel bar truss floor slab, multiple ceramic rings need to be carried, and the ceramic rings need to be placed one by one. When using a welding torch to weld the stud bolts, carrying too many makes movement difficult, and the welded ceramic rings need to be broken, a hammer needs to be carried again, and the welded stud bolts may be offset when breaking.

[0006] To solve the above technical problem, an embodiment of this application provides a welding processing device for a steel bar truss floor slab, including a machine body. A fixed rod is provided on the same end face of the welding pipe of the machine body, and further includes:

[0007] Arc-shaped clamping plates, which are arranged at the end face of the machine body. There are two of them, and they can rotate around the fixed rod to face the opening of the welding pipe.

[0008] A limiting frame, which is arranged on the side of the fixed rod. It is a frame combined with a circular shape and a square shape, which can prevent the ceramic ring from falling off.

[0009] A rotating clamping unit is provided on a fixed rod. When it rotates around the fixed rod and reaches the limit frame, it can push the limit frame open, causing the porcelain ring to fall into the two arc-shaped clamping plates. At the same time, after welding is completed, the two arc-shaped clamping plates can be opened by controlling the rotating clamping unit, and the porcelain ring can be quickly released and then crushed by extrusion.

[0010] In some embodiments, the rotating clamping unit includes a bottom plate provided at the bottom end of the fixed rod. Two transverse plates are movably provided on the top of the bottom plate. The two arc-shaped clamping plates are respectively fixed at the ends of the corresponding transverse plates. A segmented wedge block is provided on the top of the two transverse plates, and the segmented wedge block can be separated when the two transverse plates open and close.

[0011] In some embodiments, two T-shaped straight plates are provided on the top of the bottom plate. T-shaped grooves are opened at the bottoms of the two transverse plates, and the two T-shaped straight plates are respectively movably provided in the corresponding T-shaped grooves.

[0012] In some embodiments, a lifting rod is movably provided inside the bottom plate. A double-sided groove plate is movably sleeved on the outer surface of the lifting rod. Grooves are opened on the top sides of the two transverse plates close to the lifting rod. Rotating plates are movably provided inside the two grooves. The end faces of the two rotating plates away from the corresponding grooves are respectively movably provided in the grooves on the side edges of the corresponding double-sided groove plates. A strong spring is sleeved on the outer surface of the lifting rod. The bottom end of the strong spring is provided on the top of the bottom plate, and a linkage assembly for controlling the movement of the lifting rod is provided at the top end of the lifting rod.

[0013] In some embodiments, the linkage assembly includes a knob ring provided at the top end of the lifting rod. A sleeve ring is provided on the inner wall of the knob ring. A connecting ring is movably sleeved on the outer surface of the sleeve ring. The inner wall of the connecting ring is movably sleeved on the fixed rod. A plurality of guide rods are provided on the outer surface of the fixed rod. A plurality of guide grooves are opened on the inner side of the connecting ring, and the plurality of guide rods are respectively movably provided in the corresponding guide grooves.

[0014] In some embodiments, a first connecting rod is provided at the top end of the connecting ring. The top end of the first connecting rod is provided with a linkage ring sleeved on the machine body. A second connecting rod is provided at the top end of the linkage ring. The top end of the second connecting rod passes through the handle of the machine body and is provided with a pressing plate. A third spring is sleeved on the outer surface of the second connecting rod. The bottom end of the third spring is provided on the machine body. A porcelain ring conveying assembly for opening the limit frame in an orderly manner and dropping the porcelain ring is provided on the fixed rod.

[0015] In some embodiments, the porcelain ring conveying assembly includes a sleeve plate sleeved on a fixed rod. A connecting plate is arranged on the side of the sleeve plate. A porcelain ring storage cylinder is arranged on the side of the connecting plate away from the sleeve plate. A plurality of porcelain rings are stacked inside the porcelain ring storage cylinder. Two L-shaped plates are arranged at the bottom of the connecting plate. The tops of the two L-shaped plates are movably arranged at the bottom of a limiting frame. The inner side of the limiting frame is closely attached to the bottom end of the porcelain ring.

[0016] In some embodiments, a connecting groove is formed in the side of the connecting plate. An inclined surface sleeve is movably arranged on the inner wall of the connecting groove. A moving block is arranged on the outer surface of the inclined surface sleeve. The moving block is movably arranged on the inner wall of the connecting groove. The bottom end of the moving block is arranged on the top of the limiting frame.

[0017] The inclined surface of the inclined surface sleeve corresponds to the inclined surface of the segmented wedge block. When the segmented wedge block rotates around the fixed rod, the inclined surface of the segmented wedge block can squeeze the inclined surface of the inclined surface sleeve, so that the moving block drives the limiting frame to move, and the porcelain rings inside the porcelain ring storage cylinder can be dropped into the inside of two arc-shaped clamping plates.

[0018] In some embodiments, a guide post is arranged on the inner wall of the connecting groove. The outer surface of the guide post is movably arranged inside the inclined surface sleeve. A second spring is sleeved on the outer surface of the guide post. Two ends of the second spring are respectively arranged on the end surface of the inclined surface sleeve and the inner wall of the connecting groove.

[0019] When the segmented wedge block squeezes the inclined surface sleeve, the inclined surface sleeve is also squeezed against the second spring. After the segmented wedge block moves away from the inclined surface sleeve, the inclined surface sleeve can be reset to realize multiple continuous uses.

[0020] In some embodiments, an inertia hammer assembly is arranged on the inner side of the arc-shaped clamping plate for hammering and crushing the welded porcelain rings by inertia. A plurality of circular grooves are formed in the inner side of the arc-shaped clamping plate. The inertia hammer assembly includes cones movably arranged on the inner walls of the plurality of circular grooves. Tension springs are arranged between the end surfaces of the plurality of cones and the inner walls of the corresponding circular grooves.

[0021] The present invention has at least the following beneficial effects:

[0022] Through the collaborative operation of the set rotary clamping unit and the porcelain ring conveying component, when the rotary clamping unit rotates slowly, it will drive the arc-shaped clamping plate to move to the position of the porcelain ring conveying component. At this time, the circular part of the limit frame avoids the porcelain ring, while the square part reaches the edge of the porcelain ring, prompting the porcelain ring to smoothly slide into the arc-shaped clamping plate. As the rotary clamping unit continues to rotate, the porcelain ring is brought to the position facing the welding gun barrel. At this time, only the stud needs to be placed. This design not only realizes the one-time and efficient welding of the stud and the porcelain ring, but also the porcelain ring conveying component has the ability to load multiple porcelain rings, enabling the worker to easily complete the operation with only one tool in hand, greatly reducing the burden on the worker during the movement process;

[0023] The set rotary clamping unit and the linkage component are used in combination. After the welding is completed, a pressing operation is performed, enabling the linkage component to drive the rotary clamping unit to work. At this time, the rotary clamping unit can open the two arc-shaped clamping plates, and then directly release the linkage component. The rotary clamping unit will quickly reset, and at this time, the two arc-shaped clamping plates will directly crush the porcelain ring, and the outer surface of the stud is uniformly stressed, which can prevent deviation in one direction and is very fast, greatly increasing the work efficiency.

[0040] Embodiment 1: Please refer to Figure 1-12 , the present invention provides a technical solution: a welding processing device for a steel bar truss floor slab, including a machine body 1, a fixed rod 4 is arranged on the same end surface of the welding pipe of the machine body 1, and further includes:

[0041] An arc-shaped clamping plate 2, the arc-shaped clamping plate 2 is arranged at the end surface of the machine body 1, there are two of them, and it can rotate around the fixed rod 4 to face the opening of the welding pipe, and the inner side of the arc-shaped clamping plate 2 is concave-convex;

[0042] The limit frame 3 is arranged on the side of the fixed rod 4. It is a frame with a combined circular and square shape, which can prevent the ceramic ring from falling. The inner side of the limit frame 3 is in contact with the bottom end of the ceramic ring.

[0043] The rotary clamping unit 5 is arranged on the fixed rod 4. When it rotates around the fixed rod 4 and reaches the limit frame 3, it can push the limit frame 3 to open, so that the ceramic ring falls into the two arc-shaped clamping plates 2. At the same time, after welding is completed, the two arc-shaped clamping plates 2 can be opened by controlling the rotary clamping unit 5, and the ceramic ring can be quickly loosened and then crushed.

[0044] The rotary clamping unit 5 includes a bottom plate 51 arranged at the bottom end of the fixed rod 4. Two transverse plates 52 are movably arranged on the top of the bottom plate 51. The two arc-shaped clamping plates 2 are respectively fixed at the ends of the corresponding transverse plates 52. A segmented wedge block 54 is arranged on the top of the two transverse plates 52. The segmented wedge block 54 can be separated when the two transverse plates 52 open and close, and the segmented wedge block 54 can move away from each other when the two transverse plates 52 move.

[0045] Two T-shaped straight plates 56 are arranged on the top of the bottom plate 51. T-shaped grooves 57 are opened at the bottoms of the two transverse plates 52, and the two T-shaped straight plates 56 are respectively movably arranged in the corresponding T-shaped grooves 57. The settings of the T-shaped straight plates 56 and the T-shaped grooves 57 can provide a limiting effect for the transverse plates 52 and also have a guiding function.

[0046] A lifting rod 53 is movably arranged inside the bottom plate 51. A double-sided groove plate 55 is movably sleeved on the outer surface of the lifting rod 53. Grooves 59 are opened on the top sides of the two transverse plates 52 close to the lifting rod 53. Rotating plates 510 are movably arranged inside the two grooves 59. The end faces of the two rotating plates 510 away from the corresponding grooves 59 are movably arranged in the grooves on the sides of the corresponding double-sided groove plates 55. A strong spring 58 is sleeved on the outer surface of the lifting rod 53. The bottom end of the strong spring 58 is arranged on the top of the bottom plate 51. A linkage component 7 for controlling the movement of the lifting rod 53 is arranged at the top end of the lifting rod 53. The strong spring 58 can quickly drive the arc-shaped clamping plates 2 to squeeze the ceramic ring when reset, so that the ceramic ring is broken.

[0047] The linkage component 7 includes a knob ring 78 arranged at the top end of the lifting rod 53. A sleeve ring 75 is arranged on the inner wall of the knob ring 78. A connecting ring 72 is movably sleeved on the outer surface of the sleeve ring 75. The inner wall of the connecting ring 72 is movably sleeved on the fixed rod 4. A plurality of guide rods 710 are arranged on the outer surface of the fixed rod 4. A plurality of guide grooves 74 are opened on the inner side of the connecting ring 72. The plurality of guide rods 710 are respectively movably arranged in the corresponding guide grooves 74. The guide rods 710 and the guide grooves 74 can make the connecting ring 72 slide on the outer surface of the fixed rod 4 and at the same time prevent the connecting ring 72 from rotating.

[0048] A connecting rod 71 is provided at the top end of the connecting ring 72. A linkage ring 73 sleeved on the machine body 1 is provided at the top end of the connecting rod 71. A connecting rod 79 is provided at the top end of the linkage ring 73. A pressing plate 76 is provided at the top end of the connecting rod 79 through the handle of the machine body 1. A spring three 77 is sleeved on the outer surface of the connecting rod 79. The bottom end of the spring three 77 is provided on the machine body 1. A porcelain ring conveying assembly 6 for opening the limiting frame 3 and orderly dropping porcelain rings is provided on the fixed rod 4. By pressing the pressing plate 76, the connecting ring 72 can be driven to move through the connecting rod 79, the linkage ring 73 and the connecting rod 71. The provided spring three 77 plays a resetting effect to prevent the pressing plate 76 from getting stuck.

[0049] The porcelain ring conveying assembly 6 includes a sleeve plate 61 sleeved on the fixed rod 4. A connecting plate 63 is provided on the side of the sleeve plate 61. A porcelain ring storage cylinder 62 is provided on the side of the connecting plate 63 away from the sleeve plate 61. A plurality of porcelain rings are stacked inside the porcelain ring storage cylinder 62. Two L-shaped plates 68 are provided at the bottom of the connecting plate 63. The tops of the two L-shaped plates 68 are movably provided at the bottom of the limiting frame 3. The inner side of the limiting frame 3 is closely attached to the bottom end of the porcelain ring. The provided two L-shaped plates 68 can enable the limiting frame 3 to slide, so that the porcelain rings in the porcelain ring storage cylinder 62 fall.

[0050] A connecting groove 65 is formed on the side of the connecting plate 63. An inclined surface sleeve 64 is movably provided on the inner wall of the connecting groove 65. A moving block 69 is provided on the outer surface of the inclined surface sleeve 64. The moving block 69 is movably provided on the inner wall of the connecting groove 65. The bottom end of the moving block 69 is provided on the top of the limiting frame 3;

[0051] The inclined surface of the inclined surface sleeve 64 corresponds to the inclined surface of the segmented wedge block 54. When the segmented wedge block 54 rotates around the fixed rod 4, the inclined surface of the segmented wedge block 54 can squeeze the inclined surface of the inclined surface sleeve 64, so that the moving block 69 drives the limiting frame 3 to move, and the porcelain rings inside the porcelain ring storage cylinder 62 can be dropped into the inside of the two arc-shaped clamping plates 2. The inclined surface of the inclined surface sleeve 64 corresponds to the inclined surface of the segmented wedge block 54. When passing through the segmented wedge block 54, the inclined surface sleeve 64 can be squeezed to move.

[0052] A guide post 67 is provided on the inner wall of the connecting groove 65. The outer surface of the guide post 67 is movably provided on the inner wall of the inclined surface sleeve 64. A spring two 66 is sleeved on the outer surface of the guide post 67. The two ends of the spring two 66 are respectively provided on the end surface of the inclined surface sleeve 64 and the inner wall of the connecting groove 65;

[0053] When the segmented wedge block 54 presses against the inclined surface sleeve 64, it also causes the inclined surface sleeve 64 to press against the second spring 66. After the segmented wedge block 54 moves away from the inclined surface sleeve 64, the inclined surface sleeve 64 can be reset to achieve multiple continuous uses. The inner side of the limit frame 3 is provided with an arc, which can correspond to the end face of the porcelain ring. When reset by the second spring 66, the previous porcelain ring will be pressed and stuck to prevent it from falling. When the arc-shaped clamping plate 2 passes by next time, it can fall again.

[0054] When using this device, first, it is necessary to rotate the knob ring 78 to drive the rotation of the inner sleeve ring 75. The sleeve ring 75 will rotate around the fixed rod 4. At this time, the knob ring 78 will drive the lifting rod 53 to rotate. The lifting rod 53 drives the bottom plate 51 arranged on its outer surface to rotate around the fixed rod 4. Before the bottom plate 51 drives the arc-shaped clamping plate 2 and the segmented wedge block 54 to move to the limit frame 3, the inclined surface of the segmented wedge block 54 will first contact the inclined surface sleeve 64. When the segmented wedge block 54 rotates to the inclined surface sleeve 64, the inclined surface sleeve 64 will press against the second spring 66 and slide on the outer surface of the guide post 67 at the same time. The inclined surface sleeve 64 drives the moving block 69 arranged on its outer surface to slide inside the connecting groove 65. The moving block 69 will drive the limit frame 3 to slide on the two L-shaped plates 68. Moving the limit frame 3 will cause the porcelain ring at the bottom to lose its limit and fall into the inside of the arc-shaped clamping plate 2 at this time. When the arc-shaped clamping plate 2 rotates the knob ring 78 back to the starting position again, at the same time, the segmented wedge block 54 will move away from the inclined surface sleeve 64. The inclined surface sleeve 64 will be reset under the action of the second spring 66, and the reset inclined surface sleeve 64 will drive the moving block 69 to move. The moving block 69 will drive the limit frame 3 arranged at the bottom to move and reset, so that the limit frame 3 is re-stuck at the bottom end of the bottom porcelain ring to prevent the porcelain ring that has fallen into the arc-shaped clamping plate 2 from falling off when it leaves. At this time, the stud can be inserted into the porcelain ring inside the arc-shaped clamping plate 2, and the machine body 1 can be used to weld it to the steel bar truss floor slab.

[0055] After welding is completed, the porcelain ring needs to be crushed. Press the pressing plate 76 with the thumb, causing the pressing plate 76 to drive the second connecting rod 79 to descend. At the same time, the pressing plate 76 will squeeze the third spring 77 and cause deformation. The second connecting rod 79 drives the linkage ring 73 to slide on the outer surface of the machine body 1. The linkage ring 73 drives the first connecting rod 71 to descend. The first connecting rod 71 drives the connecting ring 72 at the end face to move. Since a guiding groove 74 is provided on the inner side of the connecting ring 72, the connecting ring 72 will slide on the outer surface of the guiding rod 710. Therefore, it can drive the collar 75 and the knob ring 78 to descend. The knob ring 78 drives the lifting rod 53 to descend. The lifting rod 53 drives the powerful spring 58 provided on the outer surface to deform, causing the lifting rod 53 to slide within the bottom plate 51. When the lifting rod 53 is squeezed, it will drive the double-sided groove plate 55 to descend. The double-sided groove plate 55 drives the rotating plates 510 in the two side grooves to move. The rotating plates 510 drive the transverse plate 52 provided at the end face to move. Since the T-shaped groove 57 provided at the bottom of the transverse plate 52 slides on the outer surface of the T-shaped straight plate 56, it will drive the two arc-shaped clamping plates 2 provided at the end face to open. At this time, quickly release the pressing plate 76. The pressing plate 76 will reset under the action of the third spring 77, and at the same time drive the second connecting rod 79, the linkage ring 73, the first connecting rod 71, the connecting ring 72 and the knob ring 78 to reset. The knob ring 78 drives the lifting rod 53 to reset. The lifting rod 53 will also reset under the action of the powerful spring 58, driving the double-sided groove plate 55 to reset and move. The double-sided groove plate 55 drives the rotating plates (510) on both sides to move. The rotating plates 510 pull the transverse plate 52 to reset and move. Therefore, the transverse plate 52 drives the two arc-shaped clamping plates 2 to move relatively quickly, squeezing the porcelain ring inside and crushing it.

[0056] Embodiment 2: Please refer to Figure 13-14 , the present invention provides a technical solution: An inertia hammer assembly 8 is provided on the inner side of the arc-shaped clamping plate 2 for hammering and crushing the welded porcelain ring by inertia. A plurality of circular grooves 81 are provided on the inner side of the arc-shaped clamping plate 2. The inertia hammer assembly 8 includes cones 82 movably arranged on the inner walls of the plurality of circular grooves 81. A tension spring 83 is provided between the end faces of the plurality of cones 82 and the inner walls of the corresponding circular grooves 81. When the powerful spring 58 drives the arc-shaped clamping plate 2 to reset, it will first drive the arc-shaped clamping plate 2 to reset. At the same time, the cone 82 will not move immediately, and at the same time, it will squeeze the tension spring 83 at the end face. When the arc-shaped clamping plate 2 reaches the outer surface of the porcelain ring, the cone 82 resets in the second time, impacts the porcelain ring, and impacts back and forth. Each impact is less powerful than the previous one until it resets under the action of the tension spring 83.
