Laser welding fixture

Abstract

The invention provides a laser welding fixture. The laser welding fixture comprises a bottom plate, a driving device and a clamping device, wherein the bottom plate is used for placing workpieces; the driving device is in driving connection with the bottom plate and is used for adjusting an included angle between the bottom plate and a first direction; the clamping device is arranged on the bottom plate and is used for fixing positions of the workpieces in the bottom plate. Through the technical scheme, the problem that the incident angle between the welded workpieces and the laser welding cannot be adjusted in the prior art can be solved.

Description

technical field

[0001] The invention relates to the technical field of laser welding, in particular to a laser welding fixing device. Background technique

[0002] At present, in the field of rail transit, based on various advantages of laser welding, laser lap welding technology is gradually replacing spot welding technology.

[0003] Patent No. CN 104942454A provides a laser welding construction device, which uses the magnetic force generated by the electro-permanent magnetic field to clamp stainless steel, which eliminates the gap between the workpieces and ensures the tight fit between the workpieces. The invention can realize the close bonding of workpieces, but the incident angle of the laser beam cannot be adjusted when the laser beam is fixed.

[0004] Patent No. CN 105499867A provides a thin-plate laser welding fixture, which is provided with a substrate box on the base, and a Y-direction sliding fastening plate that is slidably matched with the substrate box is pr...
