Embodiment Construction
[0028] The present invention will be further described below according to the accompanying drawings and embodiments.
[0029] An asynchronous control method for horizontal welding of large heavy-duty steel members, comprising the following steps:
[0030] A. Build the digital model of the 3D workstation and establish the database of the full position of the workpiece. The specific process is as follows:
[0031] A1. Build 3D models of relevant workpieces, positioners and fixtures: use 3D design software to build an initial 3D design workstation with 3D models of asynchronous control positioners, excavator arm workpieces and supporting fixtures, in which the positioner remains unchanged as the base , workpieces and fixtures are reorganized to establish a new three-dimensional model of the workstation according to the design requirements.
[0032] A2. Feasibility of simulating related workpiece welds to flat position: Based on the digital model of the three-dimensional workstat...

The invention belongs to the technical field of flat welding control methods for steel components, and specifically relates to an asynchronous control method for flat welding of large heavy-duty steel components, specifically: building a three-dimensional model of related workpieces, positioners and fixtures; Feasibility of flat position; Static load force analysis of workpiece; Turnover displacement torque and moment of inertia analysis of workpiece; Force analysis of asynchronous lifting of workpiece; Output related workpiece full position state data parameter group; Design workpiece upper part~ Synchronous / asynchronous displacement to the logic program of the unloading process to realize the automatic execution of the whole process; design the workpiece synchronous lifting and flipping displacement control program; design the workpiece left high right low asynchronous displacement control program; design the workpiece left low right high asynchronous displacement Control program; design workpiece out-of-tolerance compensation, fault alarm and safety self-locking program to realize closed-loop feedback and safety control; output a complete set of logic control program for related workpieces. The method can efficiently weld large heavy-duty steel components flat.
Description
technical field [0001] The invention belongs to the technical field of horizontal welding control methods for steel components, and in particular relates to an asynchronous control method for horizontal welding of large heavy-duty steel components. Background technique [0002] Taking the mining excavator as an example, the structure of the arm of the mining excavator is mostly "arched", and the front and rear ends are connected by butt welds, but the location is on a slope of 20°~40°, and welding is difficult , The weld forming quality is unreliable. More than 70% of the structural parts in the market are cracked by weld seams. If the situation is serious, it will directly lead to the scrapping of the overall structural parts and cause serious economic losses. Moreover, due to the complex technical characteristics of the boom manufacturing process and the harsh working environment of mining equipment, at this stage, the average service life of the boom structural parts of ...
