Automatic feeding system for door plank resistance spot welding

The invention relates to an automatic feeding system for door plank resistance spot welding. The automatic feeding system mainly comprises door plank installation platforms (100), screw rod guide rods (101), a terminal support (102), vertical guide rods (103), bases (104), a transmission screw rod (105), vertical supports (106), Y-direction stepping motors (107), electric lifting rods (108), an electrical control box (109), a platform support (110), an X-direction stepping motor (111) and an elastic coupler (112). According to the purpose of the automatic feeding system for door plank resistance spot welding, the automatic feeding system can be used in cooperation with a resistance spot welding machine, a door plank is fixed to the installation platforms (100), automatic feeding and automatic positioning of the door plank are achieved through the X-direction stepping motor (111), the Y-direction stepping motors (107) and the electric lifting rods (108), original manual feeding and manual positioning are repla
