Abstract

The invention discloses a friction stir welding device, a knife handle and a welding method using the welding device. According to the friction stir welding device, a sensor is arranged on the knife handle, one end of the knife handle is connected with an electric spindle, and the other end of the knife handle is connected with a friction stir welding tool. The spindle drives the knife handle andthe friction stir welding tool to rotate at high speed, and the tool machines a workpiece to be machined by contact. In the process of machining, pressure, torque and temperature of the spindle are accurately measured, at the same time, a composite grating ruler collects displacement and the speed is collected by an encoder, and high quality welding of friction stir welding is realized through theclosed-loop dynamic control of key process parameters such as displacement and speed.

Description

technical field [0001] The invention relates to welding technology, in particular to a friction stir welding welding device, a tool handle and a welding method using the welding device. Background technique [0002] The control of friction stir welding quality is mostly concentrated on the single parameter of welding upsetting force (pressure). In fact, the key parameters affecting the quality of friction stir welding are not only upsetting force, but also factors such as torque, welding temperature, and welding speed. The result of a comprehensive factor; second, most constant pressure control systems are realized by hydraulic means, but this system is not directly affected by the stirring tool, and cannot adapt to the large fluctuation of the workpiece surface due to its own insufficient feedback speed. Third, a small number of existing sensors are installed on the handle of the tool for pressure control. Because only force control is considered, when welding the protrudin...
