Scribing machine water tank welding process method and welding auxiliary device

Abstract

The invention belongs to the technical field of welding, and provides a scribing machine water tank welding process method and a welding auxiliary device. The method specifically comprises the following steps: 1, the mesh generation is carried out on a water tank model, the distribution of residual stress after welding is analyzed, and a sheet metal part splicing structure is designed; 2, distribution and positions of welding spots are designed and stipulated through a genetic algorithm; 3, the position of the welding auxiliary device compactor is set according to the welding sequence and steps; 4, the welding auxiliary device is set to be in an initial state; 5, a sheet metal part is clamped and fixed to the welding auxiliary device through a compactor; 6, welding is performed according to the distribution and positions of the obtained welding spots; 7, the upper part of the bottom surface of a water tank finished product is fully welded, and the other parts are spot-welded; and 8, after welding is completed, the clamping state of the welding auxiliary device is kept for a certain period of time, and then the welding water tank finished product is taken out. The welding auxiliarydevice comprises a welding platform, compactors, a front slideway baffle, a rear slideway baffle, slideway limiting pins, supporting angle iron, a wood tenon support, an air cylinder pressing plate, aguide rail air cylinder, a connecting plate and a U-shaped square box.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular provides a welding process method and a welding auxiliary device for a water tank of a dicing machine. Background technique [0002] The water tank of the grinding wheel dicing machine is the cutting cavity of the entire equipment, and it has a mutual relationship with the main shaft, camera, waterproof, sliding door, and other structures of the equipment. It is also a key factor to ensure the appearance of the equipment. Deformation control can not only greatly shorten the assembly time and improve work efficiency, but also improve the consistency and aesthetics of the appearance of the equipment; [0003] The water tank of the dicing machine is welded by sheet metal bending. The old process not only has low welding efficiency, but also cannot guarantee the size and post-weld deformation, and the quality of the welded product basically depends entirely on the welding level and...

Problems solved by technology

[0003] The water tank of the dicing machine is welded by sheet metal bending. The old process not only has low welding efficiency, but also cannot guarantee the size and post-weld deformation, and the quality of the welded product basically depends entirely on the welding level and welding habits of the welder. Large post-welding deformation and inaccurate position tolerances; accompanied by unsmooth sliding doors, protrusions on both sides of post-welding deformation, interference with the spindle or microscope cover, etc., greatly affect work efficiency
