| 摘要 |
The invention relates to an electric spindle with axial force control, intended for friction welding and other uses, of the type used industrially for the automated welding of metal elements or plates. The electric spindle is characterised in that the spindle body contains an integrated force sensor which is associated with the tool by means of an internal shaft that can move axially and which, via an electromechanical actuator, can be used for the real-time local adjustment of the height of the tool above the material to be worked, such as to maintain a constant axial force and a controlled position during the welding and/or machining process. The main advantage of the invention is that the height is corrected according to the force, automatically in the electric spindle itself, with much greater precision and speed, thereby providing more uniform welding results without irregularities. |
