Abstract

The invention provides an online detection device and detection method for rolling reduction of a stirring head. The online detection device comprises a temperature control box, a distance measurementdevice, an industrial personal computer and two temperature control devices, wherein the distance measurement device and the temperature control devices are connected with the industrial personal computer in a two-way communication mode; the distance measurement device comprises a first laser range finder and a second laser range finder; the first temperature control device comprises a first temperature sensor and a first temperature adjusting module; the second temperature control device comprises a second temperature sensor and a second temperature adjusting module; and the first temperature adjusting module and the second temperature adjusting module each comprise a semiconductor chilling plate, a microcontroller and a peripheral circuit. A detection system performs online measurementon the rolling reduction of the stirring head in the welding process by utilizing a triangle laser range finding technology, changes of the welding pressure can be mastered through real-time detectionof the rolling reduction of the stirring head, accordingly, effective control over the welding pressure is further achieved, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of photoelectric measurement, in particular to an on-line detection device and detection method for the depression of a stirring head. Background technique [0002] Friction stir welding, as a preferred welding technology for the connection of light alloy materials, makes the research on friction stir welding technology at home and abroad attach great importance, and the research is gradually deepening. The content of the research mainly focuses on welding machine technology, welding materials and welding equipment. In terms of the influence of welding force, the mechanism of defect formation in the weld, and the residual stress and deformation caused by friction stir welding, it can be seen from the research hotspots that the temperature changes caused by pressure and heat production during the welding process, as well as the high temperature caused by temperature changes The size of the plastic area and t...
