Description

Technical Field

[0001] The invention belongs to the field of welding equipment, and more specifically, particularly relates to welding equipment for making steel structures. Background Art

[0002] Steel structure round tube welding is a process of connecting the cuts of two or more steel structure round tubes together through welding technology, which can make the round tubes firmly combined and form a stable structure. At present, steel structure round tube welding is usually performed by welders holding electric welding guns around the butt joint of the round tube cuts. Since the weld formed by the butt joint of the two sets of round tube cuts is a ring structure, the welding process requires the welder to constantly adjust the body posture position. Each change of welding position will interrupt the welding process. It can be seen that the traditional steel structure round tube welding is intermittent due to the continuous conversion of the welding direction of the edge of the round tube cut, and the two sets of round tube cuts cannot be welded and formed quickly at one time, which reduces the welding speed of the round tube. In addition, due to the interruption of the welding process, the weld seal surface is discontinuous, and the interruption of the weld is prone to form stress concentration points, which reduces the fatigue life of the welding positions of the two sets of steel structure round tubes, resulting in cracking and damage at the welds of the two sets of round tubes.

A top plate 7 is welded to the top of the column 11, a hydraulic telescopic cylinder 6 is installed on the upper side of the top plate 7, a lifting plate 8 is installed on the bottom end of the telescopic rod of the hydraulic telescopic cylinder 6, and an electric welding machine 10 is installed on the lower side of the lifting plate 8; a rotating tube clamping device 12, a rotating drum 1201, a clamping block 1202, a pressing sleeve 1203, a guide column 1204, a return spring 1205, a rubber gasket 1206 and a bracket 1207; the outer side surface of the rotating drum 1201 is rotatably connected to the bracket 1207, and a seat plate 20 is welded to the lower side surface of the bracket 1207; the top end of the return spring 1205 is welded with the clamping block 1202, the other end of the return spring 1205 is welded to the rotating drum 1201, and the outer side surface of the rotating drum 1201 is welded with a guide column 1204.

[0027] In the disclosed embodiment, six groups of square through grooves are provided on the outer side surface of the rotating drum 1201, and the square through grooves are distributed in a circular array around the horizontal center axis of the rotating drum 1201. The inside of the square through grooves of the rotating drum 1201 is interspersed with clamping blocks 1202. The outer side surface of the rotating drum 1201 is provided with a threaded structure. The outer side surface of the rotating drum 1201 is provided with an external tooth structure near the rear end. The gear 19 is meshed and connected to the external tooth structure of the rotating drum 1201. The inner side surface of the rotating drum 1201 is interspersed with a round tube 17. The gear 19 drives the rotating drum 1201 to rotate, thereby completing the automatic steering work of the welding of the round tube 17.

[0028] In the disclosed embodiment, two groups of vertical plates are provided on the upper side surface of the bracket 1207, and the front side surface of each group of vertical plates is provided with small through holes that pass through from front to back. A transmission rotating rod 18 is rotatably connected in the small through holes of the vertical plates of the bracket 1207, and gears 19 are welded on the outer side surfaces of the transmission rotating rod 18 near the front end and the rear end. The tube rotating motor 15 drives the two groups of gears 19 to rotate synchronously through the transmission rotating rod 18, and the gears 19 drive the two groups of round tubes 17 clamped and fixed on the inner side of the rotating cylinder 1201 of the two groups of tube rotating clamping devices 12 to rotate synchronously, so as to avoid the different rotation speeds of the incision parts of the two groups of round tubes 17 causing the welds at the butt joint positions of the incisions of the two groups of round tubes 17 to be offset, thereby ensuring that the incision parts of the two groups of round tubes 17 are stably rotated and welded.

[0029] In the embodiment of the present disclosure, there are six groups of clamping blocks 1202, and the front side surface of each group of clamping blocks 1202 is a slope structure. The rear side surface of the clamping block 1202 is provided with a convex plate, and a through hole is provided at the center position of the upper side surface of the convex plate. The guide column 1204 is inserted into the convex plate through hole of the clamping block 1202, so that the clamping block 1202 can slide directionally along the guide column 1204 in the square through groove of the rotating drum 1201. The lower side surface of each group of clamping blocks 1202 is bonded with a rubber gasket 1206. The rough surface of the rubber gasket 1206 increases the contact friction between the clamping block 1202 and the outer surface of the round tube 17, so that the six groups of clamping blocks 1202 can stably clamp the round tube 17.

[0030] In the disclosed embodiment, the pressing sleeve 1203 is a cylindrical structure that passes through from front to back, and a threaded structure is provided on the inner side surface of the cylinder. The threaded outer side surface of the rotating cylinder 1201 is engaged with the threaded structure on the inner side surface of the pressing sleeve 1203. During the rotation of the pressing sleeve 1203, it rotates and moves along the threaded outer side surface of the rotating cylinder 1201. The rear end of the pressing sleeve 1203 squeezes the inclined structure of the six groups of clamping blocks 1202, so that the pressing sleeve 1203 pushes the clamping blocks 1202 to move synchronously centripetally along the square through groove of the rotating cylinder 1201, and the clamping blocks 1202 clamp and fix the round tubes 17 of different diameters in the center.

[0031] In the disclosed embodiment, a disc is provided at the top of the guide column 1204, and the diameter of the disc is larger than the diameter of the through hole of the clamping block 1202. The disc of the guide column 1204 limits the movement of the clamping block 1202 to prevent the clamping block 1202 from sliding out of the guide column 1204 under the action of the return spring 1205.

[0032] In the disclosed embodiment, a convex plate is provided at the center position of the lower side surface of the slide 2, and a threaded through hole that passes through the front and rear is provided at the center position of the front side surface of the convex plate. The outer side surface of the threaded drive rod 14 is threadedly engaged with the threaded through hole of the slide 2. Through holes are provided on the left and right sides of the threaded through hole of the convex plate of the slide 2. Two groups of guide rods 4 are respectively inserted into the convex through holes of the slide 2. The tube rotating motor 15 drives the slide 2 to move forward and backward along the guide rod 4 through the threaded drive rod 14, so that the slide 2 drives the electric welding machine 10 carried by the beam frame 9 to move horizontally forward and backward, and the welding gun head position of the electric welding machine 10 is horizontally adjusted according to the welding path shape formed by the docking of the cut edges of the two groups of round tubes 17 and the docking position of the two groups of round tubes 17.

[0033] In the disclosed embodiment, the upper side of the lifting plate 8 is provided with two groups of through holes extending vertically therethrough, and the columns 11 are inserted into the through hole structure of the lifting plate 8. The hydraulic telescopic cylinder 6 drives the lifting plate 8 to move vertically upward or downward along the columns 11, so that the electric welder 10 at the bottom of the lifting plate 8 can adjust the welding height position according to the diameter of the round tube 17.

[0034] The specific usage and function of this embodiment are as follows: When the present invention performs butt welding of two sets of steel structure round tubes, the two sets of round tubes 17 are first inserted into the rotating cylinders 1201 of the two sets of rotating tube clamping devices 12, and then the pressing sleeve 1203 is manually rotated. Since the inner side thread of the pressing sleeve 1203 is engaged with the thread structure of the outer side of the rotating cylinder 1201, the pressing sleeve 1203 moves backward along the thread of the outer side of the rotating cylinder 1201, and the rear end of the pressing sleeve 1203 squeezes the inclined surface structure of the six sets of clamping blocks 1202. At this time, the six sets of clamping blocks 1202 are moved along the rotating cylinder 1201. The square through slot and guide column 1204 of 01 move synchronously toward the center until the rubber gasket 1206 bonded to the clamping block 1202 fits tightly against the outer side of the round tube 17. The clamping blocks 1202 of the two sets of rotating tube clamping devices 12 center the two sets of round tubes 17. The control machine 5 controls the hydraulic oil supply station 3 to start through the wire. The hydraulic oil supply station 3 supplies oil to the hydraulic telescopic cylinder 6 through the oil pipe. The telescopic rod of the hydraulic telescopic cylinder 6 pushes the lifting plate 8 to slide downward along the column 11. The lifting plate 8 is installed on the lower side. The welding gun head of the welding machine 10 is close to the round tube 17, and then the control machine 5 controls the translation motor 16 through the wire to drive the threaded driving rod 14 to rotate, and the threaded driving rod 14 drives the slide 2 connected to the outer side meshing to move along the guide rod 4 in the forward and backward direction, and the slide 2 drives the column 11 connected to the beam frame 9 to move synchronously, and the welding gun head of the welding machine 10 moves horizontally to the docking position of the two groups of round tubes, and the control machine 5 controls the transmission rotating rod 18 to rotate through the wire, and the transmission rotating rod 18 drives the two groups of gears 19 connected to the outer side welding. Synchronous rotation, since the gear 19 is meshed and connected to the outer tooth structure of the rotating drum 1201, the two groups of gears 19 respectively drive the rotating drums 1201 of the two groups of rotating tube clamping devices 12 to rotate, and the two groups of rotating drums 1201 drive the inner clamping blocks 1202 to clamp and fix the round tubes 17 to rotate synchronously. At this time, the control machine 5 controls the electric welder 10 to start through the wire, and the welding gun head of the electric welder 10 performs continuous circumferential welding on the butt joint positions of the two groups of round tubes 17, thereby completing the butt welding of the two groups of round tubes 17 of the steel structure.

[0035] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, and can be implemented as long as it can achieve its beneficial effects. The control machine 5, hydraulic telescopic cylinder 6, electric welder 10, tube rotation motor 15, and translation motor 16 used above are all common components on the market. When purchased and used, they can be used by simply connecting them according to the instruction manual purchased together, so they will not be repeated here.
