Automatic welding system and method for truck frame

Abstract

The invention relates to an automatic welding system and method for a truck frame. The automatic welding system comprises an artificial stock table which is used for preparing a workpiece to be welded, an automatic conveyer car which is used for transporting the workpiece among equipment, a track which is used for the automatic conveyer car to travel, a clamping device which is used for taking the workpiece down from the automatic conveyer car and transferring to a welding position, a welding robot, a buffering table which is used for repairing welding of the workpiece after the welding and a PLC (programmable logic controller) master control system. The artificial stock table and the clamping device are arranged at two sides of the track, the PLC master control system is connected with and controls the automatic conveyer car, the welding robot, the clamping device and the buffering table through an industry field bus. The automatic welding system and method for the truck frame can greatly improve production efficiency, reasonably utilize manpower resource and realize cycle-based production.

Description

technical field [0001] The invention relates to a bogie frame automatic welding system and method, and belongs to the technical field of rail vehicle body manufacturing. Background technique [0002] At present, welding robots have gradually entered the field of domestic rolling stock manufacturing and are used in the welding production process of bogie frames. However, at present, the robots used in the production process of frame welding are all in the form of stand-alone machines. Each piece of equipment needs to be equipped with 1-2 operators to operate. The opening is manually operated, and the auxiliary time is long, which reduces the production efficiency. In addition, the program of frame welding is completely manually invoked. When multiple varieties are operated at the same time, there is a possibility of using the wrong program due to human error, which not only reduces the production efficiency, but also increases the scrap rate and increases the manufacturing c...

AI Technical Summary

Problems solved by technology

[0004] (1) Low production efficiency: the programming method is single and outdated, the accuracy of the welding track is low, and the welding efficiency is low

[0005] (2) Waste of labor resources: For automated operation equipment, the ultimate goal is generally to achieve unmanned operation, but in the above-mentioned production method, each robot needs to be equipped with 1-2 operators, and the waste of resources is obvious

[0006] (3) A lot of auxiliary time: the lifting of the workpiece, the clamping and loosening of the workpiece all require manual work, requiring a lot of auxiliary time, and the crane is used for the lifting of the workpiece, and there will inevitably be invalid waiting time for the crane

[0007] (4) The concept of production without a beat, the workpiece circulation speed is slow, and the intermediate inventory is large
