Lifting motor driven welding robot

Abstract

The invention discloses a welding robot driven by a lifting motor, comprising: a column; a rocker, which includes a first rod body, a second rod body, a third rod body and a fourth rod body arranged in the same vertical plane; a traction device, which It includes a cable, a positioning cylinder, a limit mechanism, and a first locking frame; a receiving platform, which includes a vertically arranged connecting column, a hanger horizontally arranged on one side of the connecting column, and a workbench below. A fixed seat is arranged on the working table, and a welding torch, a sleeve and a pulley assembly are arranged on the fixed seat. The present invention can realize horizontal and vertical swing through rocker arm design, selectively provide power for horizontal rotation and vertical rotation through design of lifting motor, and realize fine-tuning of workbench height through pulley design, which can realize multi-tasking Welding is carried out on a single-position frame, which has the advantages of high welding efficiency, low manufacturing cost, and flexible welding positions.

Description

technical field [0001] The invention relates to the field of welding technology. More specifically, the present invention relates to a lifting motor-driven welding robot. Background technique [0002] During the processing of the rack assembly line, it is usually necessary to weld the processed rack, and during the welding process, welding mechanical arms are arranged on both sides of the assembly line so as to weld the racks on the assembly line. There are two types of welding manipulators: mechanical and hydraulic. At present, most of the welding manipulators are hydraulically driven. Since the hydraulic drive uses hydraulic oil as the medium for power transmission, there are the following problems: the starting performance is poor, and it is easy to be damaged due to the wear of internal components. Leakage occurs, and the leaked hydraulic oil will pollute the environment. The hydraulic oil is greatly affected by temperature, the overall efficiency is low, and sometimes ...

Problems solved by technology

There are two types of welding manipulators: mechanical and hydraulic. At present, most of the welding manipulators are hydraulically driven. Since the hydraulic drive uses hydraulic oil as the medium for power transmission, there are the following problems: the starting performance is poor, and it is easy to be damaged due to the wear of internal components. Leakage occurs, and the leaked hydraulic oil will pollute the environment. The hydraulic oil is greatly affected by temperature, the overall efficiency is low, and sometimes there is noise and vibration

Hydraulic components require high processing precision, strict assembly requirements, and difficult manufacturing. Maintenance requires high technology and is difficult during use.

The mechanical welding manipulator uses mechanical transmission parts to realize the welding action, which has the advantages of being strong and durable, but the traditional single-degree-of-freedom mechanical welding manipulator cannot complete complex actions, and its application range is very limited
