Abstract

The invention relates to a large-size workpiece weld holder, comprising a supporting arm consisting of a welding arm and a hinge arm, wherein the hinge arm is of multiple sections which are connected by rotating shafts, the welding arm is fixedly arranged on the front end of the hinge arm, the welding arm is provided with a welding-gun mobile motor, a welding-gun mobile screw rod and a welding gun frame, two sides of the welding gun frame are respectively provided with a welding gun, the rear end of the hinge arm is fixedly provided with a rack screw-rod nut, the middle part of a rack is provided with a rack screw rod, the rack screw-rod nut is sleeved on the rack screw rod, the upper end and the lower end of the rack screw rod are fixed by bearings, the upper end of the rack screw rod is connected with a driving motor, a positioning frame is arranged on the side face of the welding arm, and an electromagnetic sucker is arranged below the positioning frame; and the rack is an independent stand column, the lower end of the rack is fixed on the ground, and only one supporting arm is arranged on the rack. When the large-size workpiece welding holder is used for welding, the advantages of easiness for positioning and high working efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of welding positioning frames for large workpieces. Background technique [0002] In the prior art, the welding of large workpieces needs to be completed on a large positioning device. The positioning device is composed of a bracket and a fixing seat. The bracket is composed of a column, a beam and a welding torch. The column is fixed on the ground. The end of the screw rod is equipped with a drive motor, the screw nut is installed on the screw rod, and the beam splint is installed on the screw nut. When the screw rod rotates, the screw nut drives the beam splint to move up and down, and the beam is installed on the beam splint. , a drive wheel is installed on the beam splint, the drive wheel pushes the beam to move horizontally, the welding torch is installed at the end of the beam, and the beam is perpendicular to the column; the fixed seat is composed of a bottom and a workpiece positioning wheel, and the...
