The invention discloses an automatic
welding machine for square pipes and gaskets. The
welding machine comprises an
operating table, a rotary worktable fixedly installed on the
operating table, and anautomatic
gasket feeding device, an automatic square
pipe feeding device, a
welding device and an automatic discharging device which are arranged around the rotary worktable sequentially. A welding
assembly mechanism is arranged on the rotary worktable; the rotary worktable drives the welding
assembly mechanism to circulate and operate among the automatic
gasket feeding device, the automatic square
pipe feeding device, the welding device and the automatic discharging device; and the welding
assembly mechanism receives gaskets at the automatic
gasket feeding device and square pipes at the automatic square
pipe feeding device, and assembly of the gaskets and the square pipes is completed before movement to the welding device. According to the automatic welding
machine, automatic feeding, automatic assembly and welding of the square pipes and the gaskets can be achieved, welded parts are conveyed to a discharging area, manual operation is not needed in the whole process, manpower input is reduced, the welding accuracy and the production safety are improved, the floor area is small, and the production cost is greatly reduced.
