Robot arm for pulley welding

Abstract

The invention relates to the field of welding technology. The invention discloses a pulley type welding robot mechanical arm, which comprises: a column; a main arm, which includes a first rod body, a second rod body and a third rod body which are sequentially hinged in the same vertical plane; an auxiliary arm, which includes a The fourth rod body, the telescopic frame, the fifth rod body, the sixth rod body, the seventh rod body and the eighth rod body arranged in the same vertical plane of the main arm; the receiving platform includes a vertically arranged connecting column, a horizontally arranged The hanger above one side of the connecting column and the workbench below; a sleeve and a pulley assembly. The present invention can realize horizontal and vertical swings through the design of the curved arm, fine-tuning the height of the workbench through the design of the pulley, and can perform welding on multi-station racks. The advantage of bit flexibility.

Description

technical field [0001] The invention relates to the field of welding technology. More specifically, the present invention relates to a pulley type welding robot arm. 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 there...

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 robot arm of the mechanic uses mechanical transmission parts to realize the welding action, which has the advantages of sturdiness and durability, but the traditional single-degree-of-freedom mechanical welding robot arm cannot complete complex actions, and its application range is very limited
