Gun head swing mechanism applicable to rectangular coordinate system welding robot

Abstract

The invention provides a gun head swing mechanism applicable to a rectangular coordinate system welding robot, belongs to the technical field of automation control, and solves the problems that the existing robot welding gun heads cannot swing and movement of the welding gun heads is limited to a certain degree, and welding of complex tools cannot be completed. The tail of a welding gun head of the gun head swing mechanism is connected with a wire feeding tube. The bottom of the wire feeding tube is disposed at one end of a swing rod. The other end of the swing rod is respectively hinged to the bottom of a mandrel and the bottom of a screw. The top of the screw is provided with a connecting mechanism controlled by a servo motor. The welding robot gun head swing mechanism has the advantages that the swing mechanism is small in swing radius, and can freely extend into a tool for welding, the welding gun head is large in freedom degree, welding dead angle can be eliminated, and the like.

Description

technical field [0001] The invention belongs to the technical field of automation control, and relates to a torch head swing mechanism of a rectangular coordinate system welding robot. Background technique [0002] Welding robots are mainly used to replace manual welding work. At present, the more common welding robots include Cartesian coordinate system robots and articulated robots. The swing of the torch head of the articulated welding robot is mainly realized by the joints. Due to the long distance between the joint and the torch head and the large swing radius, it cannot penetrate into the small and complicated tooling, and there are some welding dead ends. Due to the complex structure and high cost of articulated welding robots, it is difficult to promote them in small and medium-sized enterprises with a large volume and a wide range. At present, cheap Cartesian coordinate system welding robots have been released on the market, such as: a Cartesian coordinate system ...

Problems solved by technology

The swing of the welding torch head of the articulated welding robot is mainly realized by the joints. Due to the long distance between the joint and the welding torch head and the large swing radius, it cannot penetrate into the small and complicated tooling, and there are some welding dead ends.

Due to the complex structure and high cost of articulated welding robots, it is difficult to promote them in small and medium-sized enterprises with a large volume and a wide range

At present, cheap Cartesian coordinate system welding robots have been released on the market, such as: a Cartesian coordinate system welding robot device has been announced in the Chinese patent document CN103111777A. Due to the limitation, it is impossible to realize the welding of complex tooling
