a pressing unit disposed adjacent to the second jig and selectively pressurizing the second jig to contact the first pin part, the second pin part, and the scaffolding part; and
A welding part disposed adjacent to the first jig and the second jig and welding the first pin part, the second pin part, and the scaffolding part while the first pin part, the second pin part, and the scaffolding part rotate in contact with each other; Including,
a first driving shaft connecting the first jig and the driving unit;
a second driving shaft connected to the second jig and rotating the second jig;
a drive connecting shaft that is spaced apart from the first drive shaft and transmits a driving force; and
a chain unit connecting the first driving shaft and the second driving shaft to the driving connecting shaft; and
A processor connected to the driving unit, the pressing unit, and the welding unit to control the driving unit, the pressing unit, and the welding unit; further comprising;
The pressing part,
a pressure shaft selectively contacting the second drive shaft; and
Further comprising: a pressing motor connected to the pressing shaft and selectively pressurizing the pressing shaft;
The second driving shaft further includes a contact sensor disposed at one end of the second driving shaft to detect whether or not contact is made with the pressing shaft,
the processor,
Detecting whether the pressure shaft is in contact with the second drive shaft through the contact sensor;
When the pressing shaft contacts the second driving shaft, the first jig, the second jig, and the scaffolding part are rotated,
While the first jig, the second jig, and the scaffolding part rotate, the first pin part, the second pin part, and the scaffolding part are welded through the welding part,
Each of the first jig and the second jig,
a fixing unit disposed to be slidable in the first jig and the second jig and inserted into the scaffolding unit; and
A coupling portion disposed to be slidable in the first jig and the second jig and inserted into the fixing portion to press the fixing portion toward the inner surface of the scaffolding portion;
The fixing part,
a plurality of protrusions disposed at predetermined intervals and protruding from an inner circumferential surface of the fixing part;
a first contact portion disposed on an outer circumferential surface of each of the plurality of protruding portions and contacting an inner circumferential surface of the scaffolding portion; and
Automatic welding apparatus for manufacturing scaffolding system comprising a; second contact portion disposed between the first contact portion and each of the plurality of protrusions and connecting the first contact portion and the plurality of contact portions. delete delete According to claim 1,
The fixing part has a plurality of fixing grooves formed at predetermined intervals on the outer circumferential surface of the fixing part,
Each of the plurality of fixing grooves has a shape complementary to each of the plurality of protrusions,
The fixing part protrudes along the outer circumferential surface of the fixing part and interferes with the connectors of the first pin part and the second pin part to fix the first pin part and the second pin part to the scaffolding part; system further comprising a system Automatic welding device for scaffold manufacturing. According to claim 4,
the processor,
Based on the welding amount input by the user, the rotational speed of the first pin part, the second pin part, and the scaffolding part through the driving part and the length of the coupling part inserted into the scaffolding part along the longitudinal direction of the scaffolding part decide,
The fixing part is inserted into the scaffolding part, and the fixing part is controlled to be inserted with the determined length,
The determined length and the determined rotational speed are automatic welding devices for manufacturing system scaffolds that are proportional to the amount of welding input by the user.
