Abstract

The invention relates to a flexible pressing wheel mechanism and a self-adaptive laser welding device. The flexible pressing wheel mechanism comprises a fixing frame, a sliding rod, a connecting rod,a pressing wheel and two springs, the structure is simple, the size is small, relative to the structure of the pressing wheel driven by an air cylinder, so that the problem of interference with otherequipment can be avoided. Meanwhile, the pressing wheel is installed at the bottom end of the sliding rod, one spring is correspondingly connected with one end of the connecting rod and the fixing frame, and the other spring is connected with the other end of the connecting rod and the fixing frame correspondingly; and when the pressing wheel rolls on the plate with the changed height, the heightchange of the pressing wheel is directly counteracted by the stretching and the retracting of the springs, so that enough pressing force of the pressing wheel to the plate can be guaranteed, deformation caused by thermal stress in the laser welding process of the plate can be effectively inhibited, so that a constant distance range can be kept between a laser welding head and a machining area, andthe quality of a welding seam is improved.

Description

technical field

[0001] The invention relates to the technical field of laser welding, in particular to a flexible pressure wheel mechanism and an adaptive laser welding device. Background technique

[0002] As an advanced welding technology, laser welding technology has been more and more widely used and developed in the fields of automobile, energy, aerospace and other fields. At present, the frame floor welding method of large trucks is mainly manual stitch welding. If laser stitch welding is adopted, it can greatly save labor costs, save energy, reduce emissions, and improve production efficiency. However, due to the uneven surface of the frame floor of the truck and poor manufacturing accuracy, the height changes before and after the welding seam are large. This requires a mechanism for pressing the plate that can adapt to the height change of the plate.

[0003] Most of the traditional laser stitch welding equipment adopts the cylinder to drive the compression mechanis...
