[0014] The present invention provides a pipeline flange precision welding device, which has the following beneficial effects: (1) The present invention uses an electric slide, an L-shaped frame, a V-shaped frame, a round roller, a second chuck, a spring, a round plate, a vertical plate, a guide rod and a double-hole iron plate in conjunction with a straight rod. Under the action of the extrusion force, the round plate and the L-shaped frame are in contact, and the spring on the round plate begins to shrink.

[0016] (3) The present invention arranges the soldering device so that the L-shaped strip, H-shaped frame, liquid storage tank, liquid pump, frame rod, ring inclined plate, electric liquid spray head, L-shaped rod and square box cooperate with the liquid guide tube. The electric liquid spray head sprays the soldering flux evenly on the interface between the pipe and the flange, so that the interface between the pipe and the flange is evenly covered with the soldering flux, thereby preventing the interface between the pipe and the flange from having no soldering flux, thereby preventing the soldering device from having a poor soldering effect due to the lack of soldering flux. Moreover, the soldering flux dripped from the electric liquid spray head is collected by the square box, and the soldering flux in the square box enters the liquid guide tube, which transports the soldering flux into the liquid storage tank, thereby allowing the soldering flux dripped from the electric liquid spray head to be recycled and reused, thereby preventing the large amount of soldering flux dripped from the electric liquid spray head from wasting the soldering flux when the equipment is in use.

The square box 89 is located below the electric liquid spray head 87. The flux dripped from the electric liquid spray head 87 is collected by the square box 89. The flux in the square box 89 enters the liquid guide tube 810. The liquid guide tube 810 transports the flux into the liquid storage tank 83, so that the flux dripped from the electric liquid spray head 87 can be recycled and reused, thereby avoiding the large amount of flux dripped from the electric liquid spray head 87 when the welding device is in use, causing the equipment to waste flux when in use.

[0027] When the L-shaped frame 112 drives the vertical plate 121 to move to the left, the vertical plate 121 drives the short rod 71 to move to the left, the short rod 71 drives the long plate 72 to move to the left, the long plate 72 drives the thin rod 73 to move to the left, the thin rod 73 drives the U-shaped arc plate 74 to move to the left, and the U-shaped arc plate 74 drives the roller 75 to move to the left. Under the action of friction, the roller 75 rolls on the operating table 1, reducing the platform amplitude of the electric slide 111, so that the pipeline on the L-shaped frame 112 will not shake violently when the pipeline moves to the left for docking, thereby preventing the pipeline on the L-shaped frame 112 from shaking violently when the equipment is in use, thereby avoiding the problem of inaccurate equipment docking caused by the pipeline on the L-shaped frame 112 shaking violently when the welding device is in use.

[0028] While the long plate 72 drives the thin rod 73 to move left, the thin rod 73 drives the double-ring rod 76 to move left, the double-ring rod 76 drives the arc-shaped spring piece 77 to move left, and the arc-shaped spring piece 77 drives the chamfering block 78 to move left, so that when the chamfering block 78 moves to the left, the chamfering shovel of the chamfering block 78 moves the welding slag on the operating table 1 to the left, preventing a large amount of welding slag from accumulating on the operating table 1 when the equipment is in use, thereby avoiding the problem of a large amount of welding slag on the operating table 1 causing unsmooth docking of the pipe and the flange when the welding device is in use.

[0029] When the thin rod 73 drives the double ring rod 76 to move to the left, the double ring rod 76 drives the L-shaped strip 81 to move to the left, the L-shaped strip 81 drives the H-shaped frame 82 to move to the left, the H-shaped frame 82 drives the liquid storage tank 83 to move to the left, and the liquid storage tank 83 drives the liquid pump 84 to move to the left. At the same time, the double ring rod 76 drives the frame rod 85 to move to the left, the frame rod 85 drives the ring inclined plate 86 to move to the left, and the ring inclined plate 86 drives the electric liquid spray head 87 to move to the left. When the pipe and the flange are connected, the servo motor shaft in the electric slide 111 stops rotating. In the process of starting the motor in the drive module 5, the liquid pump 84 is started. The liquid pump 84 extracts the flux from the liquid storage tank 83, and the liquid pump 84 inputs the flux into the electric liquid spray head 87 through the infusion hose, and the electric liquid spray head 87 is started. The electric liquid spray head 87 sprays the flux to the interface between the pipe and the flange, so that when the pipe and the flange rotate forward, the electric liquid spray head 87 evenly sprays the flux on the interface between the pipe and the flange, so that the interface between the pipe and the flange is evenly covered with flux, thereby preventing the pipe and the flange interface from having no flux during welding when the equipment is in use, thereby avoiding the problem of poor welding effect of the welding device caused by the lack of flux at the interface between the pipe and the flange when the welding device is in use.

[0030] While the double-ring rod 76 drives the L-shaped strip 81 to move to the left, the L-shaped strip 81 drives the L-shaped rod 88 to move to the left, the L-shaped rod 88 drives the square box 89 to move to the left, and the square box 89 drives the liquid guide tube 810 to move to the left. When the electric liquid spray head 87 sprays flux, the flux dripped from the electric liquid spray head 87 is collected by the square box 89, and the flux in the square box 89 enters the liquid guide tube 810. The liquid guide tube 810 transports the flux into the liquid storage tank 83, so that the flux dripped from the electric liquid spray head 87 can be recycled and reused, preventing the electric liquid spray head 87 from dripping a large amount of flux when the equipment is in use, thereby avoiding the problem of a large amount of flux dripped from the electric liquid spray head 87 when the welding device is in use, causing the equipment to waste flux when in use.
