Integrated type laser welding and measurement integrated device

Abstract

The invention belongs to the technical field of laser welding measurement device, and relates to an integration-typed laser welding measurement integrated device which comprises a welding head installation base, a welding head which is arranged on the welding head installation base, a camera device and an arc guideway which is arranged at the welding head installation base; the camera device is connected with a beeline guideway and the camera bracket; the beeline guideway is also connected with a numerical control rotation shaft which drives the beeline guideway; the camera bracket is connected with the welding head installation base by the arc guideway; the arc guideway is provided with a semi-round gear ring and a small gear which is engaged to the semi-round gear ring; the small gear is connected with a numerical control rotation shaft which is connected with the camera bracket; the camera bracket is also connected with a manual adjusting platform which is used for slightly adjusting the relative distance of the camera device and the welding head; the integrated device can realize the shape control and performance control of the laser welding of three-dimensional complex structure light alloy components.

Description

technical field [0001] The invention relates to the technical field of laser welding measurement devices, in particular to an integrated laser welding measurement integration device. Background technique [0002] In fields such as petrochemical, aerospace and military, parts such as pipelines and missile shells are often made by tailor welding of multiple pieces. This type of parts is a three-dimensional object that combines multiple parts to create a space, and its parts are stitched together to form a three-dimensional curve in space. Due to the shape error caused by the processing of such combined parts, the deviation caused by the welding and clamping of the combined parts, the shape error of the combined parts caused by the thermal deformation of the parts during laser welding, and other factors, it will make welding There is a certain difference between the shape of the seam and the theoretical design, which makes the joint width of the parts change to a certain exten...
