Abstract

The invention provides an X frame automatic welding system which comprises a first feeding trolley, a carrying robot, a first positioning machine, a first welding robot, a second feeding trolley, a second positioning machine, a second welding robot and a control device, wherein the carrying robot is used for automatically picking up an X frame from the first feeding trolley; the first positioning machine is used for receiving the X frame picked up by the carrying robot; the first welding robot is used for carrying out first welding on the X frame on the first positioning machine; the second feeding trolley is used for receiving the X frame which is picked up by the carrying robot and is welded on the first positioning machine; the second positioning machine is used for picking up the X frame on the second feeding trolley and overturning the X frame; the second welding robot is used for carrying out second welding on the X frame overturned on the second positioning machine; and the control device is used for controlling the feeding trolleys, the carrying robots, the positioning machines and the welding robots to work. Therefore, according to the X frame automatic welding system disclosed by the invention, the integral automatic welding production line of X frame welding can be implemented and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of excavator manufacturing, in particular to an automatic welding system for an X frame on an excavator. Background technique [0002] In the existing excavator crawler frame welding production line, the X frame is the main part of the crawler frame. The X-frame includes an X-shaped main body and an annular support seat protruding from the main body of the X-frame. The main body of the X-frame is formed by welding an X-shaped upper plate, an X-shaped lower plate and four side plates connecting the surroundings of the upper plate and the lower plate. The annular support seat is welded at the middle position of the X-shaped upper plate and the lower plate. The middle of the X-shaped upper plate and the lower plate are respectively provided with circular holes corresponding to the annular support seats. Existing excavator manufacturers assemble and weld the X-frame through the following process: First, the c...
