The utility model aims at providing a novel automatic soldering turret, include: float electrode arm, solid fixed electrode arm, digging arm be board, guiding groove plate, gyro wheel, connecting rod, piston rod of the cylinder, piston and joint even, its characterized in that: digging arm even board sets up in float electrode arm one side, float electrode arm and the digging arm even mutual fixed connection of board, the connecting rod set up in the digging arm is the board lower extreme even, the digging arm links between board and the connecting rod articulatedly each other, guiding groove plate sets up in solid fixed electrode arm one side, the gyro wheel sets up on guiding groove plate, piston rod of the cylinder set up in the connecting rod lower extreme. The utility model has the advantages of the utility model discloses use T shape articulate mode to replace traditional screw thread connection, become half hinge structure by rigid connection between connecting rod and the piston rod of the cylinder. On piston rod of the cylinder can not transmitted to X direction radial force on the connecting rod, can not influence the work efficiency of cylinder.
