Robot welding workstation used for drill mast preparation and robot welding method used for drill mast preparation

Abstract

The invention discloses a robot welding workstation used for drill mast preparation and a robot welding method used for drill mast preparation. The robot welding workstation used for drill mast preparation comprises a welding robot transfer mechanism, a head-and-tail frame moving positioner, a safety device and a corresponding electrical control unit; the welding robot transfer mechanism comprisesa stand column, a X-axis cross beam is installed on the stand column in an erected mode, a Y-axis cross beam is arranged on the X-axis cross beam, a Z-axis cross beam is arranged on the Y-axis crossbeam, and a welding robot body is arranged on the Z-axis cross beam; the head-and-tail frame moving positioner comprises two moving positioner bodies and a jacking centering mechanism, and the jackingcentering mechanism are located between the two moving positioner bodies; the safety device comprises a safety fence arranged on the outer periphery of the welding robot transfer mechanism and the head-and-tail frame mocing positioner; and the electric control unit comprises an electric control cabinet, an electric control system is arranged in the electric control cabinet, and a control box is further arranged on the electric control cabinet. An existing manual welding method is replaced, the work efficiency and productivity are improved, and the automation and mechanization level of a welding workshop are improved.

Description

technical field [0001] The present invention relates to a robot welding workstation, and more particularly, relates to a robot welding workstation for drilling mast preparation and a welding method thereof. Background technique [0002] The drill mast (also known as the mast) is the main structural part of the construction machinery rotary drilling rig, and is the installation support part of the drill pipe, the power head and the guide part of the working footage. As an important component of the mast, the middle mast has a total length of more than ten meters. It is a box-shaped beam welded structure composed of an upper mast body and a lower mast body. The guide rails are welded on both sides of the pressure plate. In the middle mast structure, the welds of the pressure plate and the sealing plate, the welds of the guide rail and the pressure plate are the main welds, and they are all distributed on the side of the central axis of the section. The mast body is composed of...

AI Technical Summary

Problems solved by technology

In the mast welding process, the quality and efficiency of welding need to be fully considered. At present, although there are many application cases of robot welding workstations at home and abroad, it is not possible to complete the main beam steel plate required for the workpiece in the same workstation at one time. , the main welding of the splicing of the square tube and the main beam, and the welding requirements of the welding seam of the bulkhead plug, accessories, etc.
