Five-axis linkage welding mechanical arm

Abstract

The invention discloses a five-axis linkage welding mechanical arm. According to the technical scheme, the five-axis linkage welding mechanical arm is characterized in that a Y-axis sliding table is fixedly connected to the top end of a horizontal base, a Z-axis sliding table is vertically arranged at the side, away from the horizontal base, of the Y-axis sliding table, the Z-axis sliding table can be connected to the Y-axis sliding table in a sliding manner, and an X-axis sliding table is arranged on the Z-axis sliding table in a sliding manner, wherein a wire feeding module is arranged at the top end of the Z-axis sliding table, a fourth-axis and fifth-axis welding gun moving mechanism is arranged on the X-axis sliding table in a sliding manner, the wire feeding module is connected withan adjustable wire outlet nozzle in the fourth-axis and fifth-axis welding gun moving mechanism through an internal Teflon wire feeding pipe, a laser welding gun is arranged on the fourth-axis and fifth-axis welding gun moving mechanism, the adjustable wire outlet nozzle is aligned with a laser beam in position, and a programmable controller is adopted in a numerical control system. Therefore, theeffects that the flexible machining capacity of laser welding can be improved, complex welding processes and tool clamps are simplified, multi-station composite circulating machining is achieved, thestructure is compact, and space is saved are achieved.

Description

technical field [0001] The invention belongs to the technical field of laser welding automation, and in particular relates to a five-axis linkage welding robot arm. Background technique [0002] Since the end of the 20th century, the automatic welding industry has also developed to a certain extent with the development of my country's technological level and the gradual maturity of the market economy. For example: simple linear crawling car, automatic girth welding machine, non-standard customized special automatic welding machine, domestic welding robot, manipulator, etc. However, due to the fact that traditional manual welding is still the mainstay in my country at present, the proportion of automated welding is less than 30%. In addition, in recent years, the recruitment of welders in enterprises has been old, jumping, and difficult, and there are also practical difficulties in the equipment procurement budget of small and medium-sized enterprises. Therefore, domestic we...
