Numerical control four-shaft welding manipulator

Abstract

The invention discloses a numerical control four-shaft welding manipulator, and provides the numerical control four-shaft welding manipulator with the advantages of capability of leveling welding wires with different model numbers, convenience to align the welding wires and improvement of the welding accuracy. The numerical control four-shaft welding manipulator is characterized in that a fixed rod is horizontally arranged at the tail end of a mechanical arm; a welding gun is fixed at one end of the fixed rod; a welding wire pushing mechanism is arranged in the position, corresponding to the welding gun, of the mechanical arm; the welding wires are fed in the welding wire pushing mechanism from a welding wire winding machine, and are pushed to a workpiece direction; the welding wire pushing mechanism comprises a shell, and a pushing piece, a leveling piece, an adjustable fixed piece and a driving mechanism arranged in the shell in sequence; the welding wires with different specifications and different diameter sizes can be adapted to; and the application range of the welding manipulator is widened. The driving mechanism can drive the pushing piece, the leveling piece and the adjustable fixed piece to move, so that the whole welding wire pushing mechanism can adapt to the welding wires with different model numbers, and the welding wires can be located in a stable working state to prevent shaking in the welding process.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a numerically controlled four-axis welding manipulator. Background technique [0002] A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Its mission is to assist or replace human work in jobs such as manufacturing, construction, or hazardous jobs. [0003] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. The feature is that various expected operations can be completed through programming, and the structure and performance have both the advantages of man and robot. [0004] The manipulator is the earliest industrial robot and the first modern robot. It can replace the heavy labor of people to ...

Problems solved by technology

[0007] Although this kind of welding manipulator is simple in structure, stable and reliable in operation, and easy to adjust, it is necessary to select the type of welding wire according to the welding object during the welding process, and in the welding process, this kind of manipulator can only push out the welding wire. The flatness cannot be guaranteed, and it is not easy to align the welding wire, which will result in inaccurate welding
