Problems solved by technology

Its disadvantages are: 1. Large arbitrariness, difficult to find the welding position, poor positioning accuracy, which affects the welding quality; The joints are inconsistent; 3. The distance between the edge of the supporting plate and the pressure plate holding the thin plate is large from the welding seam of the thin plate. Due to the extremely thin thickness of the plate, the welded part of the thin plate is deformed by heat, and the high quality and consistency of all seams at the welded part cannot be guaranteed.
Although automation is realized, the process of workpiece positioning control and image processing is complicated, and the positioning accuracy is affected by the captured image signal
In addition, the clamping electromagnet and the pneumatic clamping mechanism are distributed at a large interval, and the thin plate is easily deformed by heat during welding. It cannot ensure that the entire welding edge of the thin plate, especially the thin plate with a thickness less than 0.3m, is evenly clamped and welded.
[0004] The patent with application number 200820062771.3 describes a fixture for welding thin plates with a welding torch. Although the upper and lower pressure plates are used to evenly press the two thin plates, the distance between the edges of the two thin plates to be welded is 1.5-2 mm, and the weld seam is wide. It cannot be welded without solder. Welded together, unable to meet the tailor welding requirements of thin plates

Abstract

The invention discloses a stainless steel or nickel sheet laser tailor-welding alignment clamping device and a method. The alignment clamping device comprises an XYZ three-dimensional translation RZ one-dimensional rotation motion mechanism, a video monitoring alignment regulating mechanism and a magnet pneumatic clamping mechanism, wherein the stainless steel or nickel sheet laser tailor-welding alignment clamping device can align and position sheets through the XYZ three-dimensional translation RZ one-dimensional rotation motion mechanism and the video monitoring alignment regulating mechanism, and then clamps and fixes the stainless steel or nickel sheets by the magnet pneumatic clamping mechanism to realize the laser tailor-welding of the stainless steel or nickel sheets. The invention can solve the problem of difficult welding of the stainless steel or nickel sheets smaller than 0.3mm in thickness in laser butt welding because the sheets are easy to deform owing to easy deformation property per se and thermal stress, and guarantees the quality of tailor-welded seams.

Description

technical field [0001] The invention relates to a stainless steel or nickel thin plate laser tailor welding alignment clamping device and method, belonging to the application field of laser fine processing technology. Background technique [0002] The application of laser welding is becoming more and more widespread. Because the stainless steel or nickel plate with a thickness of less than 0.3mm is very thin, it is easy to deform and bend, and the contact surface of the two thin plates is small, and it is easily deformed after being heated during laser welding, and the amount of deformation is large. , which brings considerable difficulty to tailor welding, so the alignment of the splicing position and the positioning and clamping of the thin plate are extremely critical during thin plate tailor welding. At present, the alignment and positioning of tailor-welded thin-plate welds mainly rely on the experience of operators, who use eyes to distinguish alignment, manually move ...
