Hyperbolic trace directional tangent constant-speed welding robot device

Abstract

The invention discloses a hyperbolic trace directional tangent constant-speed welding robot device and belongs to the technical field of a welding robot. The device comprises a mechanical arm consisting of an X-axis translatable element and a Y-axis translatable element, a Z-axis rotating table, a controller, a welding power supply and a welding gun and the like, wherein a workpiece with a hyperbolic trace welding joint is controlled with a workpiece mounting table to rotate; and the welding gun is controlled with the X-axis translatable element and the Y-axis translatable element to move. According to the hyperbolic trace directional tangent constant-speed welding robot device, a three-degree-of-freedom mechanism which independently moves is used for achieving a high-quality welding function to the hyperbolic trace welding joint of the workpiece; when the welding is performed, the welding gun is placed on a normal line at a hyperbolic trace welding joint welding point all the time, the welding direction is the tangent direction of a hyperbolic trace, the tangent faces some preset fixing direction all the time, the welding speed is constant, the efficiency is high, and the manufacturing cost, maintaining cost and using cost are low; and at each point in the welding, the relative positions and gestures of the welding gun and the welding joint welding point on the workpiece are kept all the time, an optimal welding effect can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of welding robots, and particularly relates to the structural design of a hyperbolic track directional tangent constant-speed welding robot device. Background technique [0002] In aerospace, aviation, shipbuilding, petrochemical and other fields, there are a large number of equipment with hyperbolic arcs. In the production process of the equipment, the workpieces need to be welded along the hyperbolic arc track. In order to obtain high-quality welds, the workpiece needs to be welded to achieve the following multiple goals at the same time: the welding torch must always be in the flat welding position during welding, the welding torch is always straight down, and the welding direction and the hyperbolic track are in the tangent direction of the point. Consistent, the tangent line must be a horizontal line, and the welding speed remains constant. At present, the welding of hyperbolic trajectories mostly uses man...
