Dual-rocker four-axis welding position changing machine and using method thereof

Abstract

The invention relates to a dual-rocker four-shaft welding position changing machine and a using method thereof. The lower ends of two upper rockers are hinged to a rack, the upper portions of the upper rockers are hinged to an upper hydraulic cylinder, and the upper rockers can be driven by the upper hydraulic cylinder to rotate around upper rocker main shafts; the lower ends of two lower rockers are hinged to the rack, the upper portions of the lower rockers are hinged to a lower hydraulic cylinder, and the lower rockers can be driven by the hydraulic cylinder to rotate around lower rocker main shafts; the upper ends of the two upper rockers are hinged to the bottom of a rotating machine head, and the upper ends of the two lower rockers are hinged to the bottom of the rotating machine head; and a rotational chuck is arranged at the top of the rotating machine head. According to the dual-rocker four-shaft welding position changing machine and the using method, the working principle of a four-connecting-rod mechanism is adopted, an upper rocker mechanism and a lower rocker mechanism are controlled by the corresponding hydraulic cylinders to rotate, the rotating machine head is driven to achieve position changing with any height and angle, rotation of workpieces at any position can be further achieved through the rotating machine head, adjustment is flexible, and welding of the workpieces can be greatly facilitated; and through linkage of a control system and a welding robot, automatic position changing in the workpiece welding process can be achieved.

Description

technical field [0001] The invention relates to a welding positioner, in particular to a double rocker four-axis welding positioner and a method for using the same. Background technique [0002] At present, most of the commonly used welding positioners can only realize simple rotation or flipping actions, but cannot adjust and flip actions at any height in space, so they cannot meet the welding requirements of large workpieces with complex shapes, which brings inconvenience to welding operations. Contents of the invention [0003] The invention provides a double-rocker four-axis welding positioner, which adopts the working principle of a four-bar linkage mechanism. The upper rocker mechanism and the lower rocker mechanism are respectively controlled by corresponding hydraulic cylinders to drive the rotating machine head to achieve any height and angle. The rotating machine head can also realize the rotation of the workpiece at any position, and its flexible adjustment can ...
