Before the pipe fitting welding system is used, firstly, the whole welding equipment is fixed at a corresponding working position through the mounting bottom plate at the bottom of the bottom box 1, then the whole welding system is electrified through the external power supply, the working time of one-time welding operation of the driving motor 51 is recorded into the time relay 10 through the control panel 11, and then the pipe fitting welding system can be used.

Assembling the pipe fittings, namely sleeving one end of the irregular pipe fitting to be welded with an elastic rubber sleeve 710, tightly wrapping the irregular pipe fitting to be welded due to the elastic force of the elastic rubber sleeve 710, then sequentially inserting the other end of the irregular pipe fitting to be welded into the rotary drum 71 and the ring body 81 of the levelness adjusting assembly 8, pre-clamping the irregular pipe fitting to be welded under the action of the extrusion groove 74, the T-shaped extrusion rod 75 and the arc-shaped rubber cushion 76, pressing down the T-shaped limiting sleeve 7113 on the periphery of the disc 72 to enable the spline protrusion in the T-shaped limiting sleeve 7113 to slide out of the spline sleeve 7112, enabling the wire winding roller 78 to lose limiting and constraining force, rotating the wire winding roller 78 through the handle 712 by a worker, winding the elastic rubber rope 79, and when the four elastic rubber ropes 79 are wound to a tight state, pre-constraining the pipe fitting to the disc 72, loosening the T-shaped limiting sleeve 7113, resetting the T-shaped limiting sleeve 7113 under the action of a spring, enabling the spline protrusion in the T-shaped limiting sleeve 7113 to slide into the groove of the spline sleeve 7112 for limiting, then installing the other irregular pipe fitting to be welded on the set of pre-installation mechanism 7 on the right side by the same operation, adjusting whether the welding contact surfaces of the two irregular pipe fittings to be welded are aligned in a parallel and level mode, after the two irregular pipe fittings to be welded are roughly adjusted, pressing down the T-shaped limiting sleeve 7113 again, rotating the handle 712, and winding and tightening the elastic rubber rope 79 to complete the fastening of the two irregular pipe fittings to be welded.

Detecting levelness: the staff rotates twist grip 43 earlier, drive adjusting gear 44 through rotation axis 42 and rotate, because adjusting gear 44 and the meshing of tooth sleeve 47, thereby make tooth sleeve 47 move down, tooth sleeve 47 drives electron spirit level 46 through lifter 45 and moves down, when two tops of taking the welding irregular pipe fitting of electron spirit level 46's bottom contact, electron spirit level 46 begins to carry out the levelness and detects, the welding personnel only need read the testing result that shows on the electron spirit level 46 demonstration this moment, can judge whether the levelness of two taking the butt joints of welding irregular pipe fitting satisfies the welding accuracy requirement.

Fine adjustment of pipe fittings: if the requirement of welding precision is not met, a welder presses the adjusting rod 852 in a corresponding direction to make the elastic protection plate 86 contact with the surface of the pipe fitting and finely push the pipe fitting, when the pipe fitting is finely adjusted to a required position, the adjusting rod 852 can be respectively positioned and constrained at the position of the pipe fitting at the moment under the action of the conical elastic buckle 84, the clamping buckle 853, the pressing plate 854 and the clamping spring 855, the adjusting rod 852 can be outwards ejected under the action of the clamping spring 855, but the conical elastic buckle 84 is clamped with the clamping buckle 853 on the adjusting rod 852, so that the adjusting rod 852 cannot be automatically reset, if the positioning constraint of the adjusting rod 852 is to be relieved, the pressing rod 88 is only needed to be pressed, the conical elastic buckle 84 is downwards extruded from the bottom end of the pressing rod 88, the clamping buckle 853 can be outwards ejected and reset when the adjusting rod 852 is unconstrained, after the fine adjustment is finished, the rotating handle 43 is loosened, the lifting rod 45 can be, The spring and the movable plate are reset upwards under the action of the spring.

Welding operation: the welder opens the cover on the door of the top box 2, takes out the welding gun 32 embedded on the door, operates the control panel 11, and makes the central processor 9 start the electric welding set 31 and the driving motor 51 respectively, the driving motor 51 can drive the two driving belt pulleys 55 to rotate slowly through the second bevel gear 54, the first bevel gear 53 and the transmission rod 52 respectively, the two driving belt pulleys 55 drive the two rotary drums 71 to rotate through the belt and the transmission belt pulley 73 respectively, thereby driving the pipe to be welded to rotate slowly, at this moment, the time relay 10 starts to time, the welder starts to weld the contact part of the pipe, when the set working time of one-time welding operation of the driving motor 51 is reached, the pipe at this moment is indicated to rotate for a circle, thereby completing the welding operation of the pipe.

Unloading: firstly, the adjusting rod 852 of the levelness adjusting assembly 8 is reset to separate the elastic protection plate 86 from the surface of the pipe fitting, then the T-shaped limiting sleeve 7113 is pressed down to remove the restriction of the winding roller 78, so that the elastic rubber rope 79 is freely pulled out, one end of the pipe fitting is removed from the tight restriction state, the elastic rubber sleeve 710 is peeled off from the pipe fitting, and then the welded pipe fitting is horizontally pulled out leftwards or rightwards, so that the unloading can be completed.

It should be noted that the irregular pipe fitting referred to in the present invention is: the cross section of the pipe fitting is a polygonal or other irregular-shaped pipe fitting, or a curved pipe with the bending included angle of the pipe fitting being less than 30 degrees.

And those not described in detail in this specification are well within the skill of those in the art.
