| 摘要 |
<p>The invention relates to an improved automatic riveting system of the type used in robotised installations in order to enable multiple operations to be performed by one device at the same work point, such as drilling, reaming, insertion of rivets, riveting, cleaning, etc. The invention is characterised in that the system employs a multi-tool head which does not move on its own, but which is fixed to a parallel kinematic machine which performs all of the combined multi-tool head positioning movements, thereby making the necessary corrections to the offset between the different physical positions of the independent tools that are disposed on the tool head. The main advantage of the invention lies in the fact that the system dispenses with the need for complex tool-head-changing mechanisms in order to obtain different diameters for drilling and other operations, thereby significantly reducing the cost of the device while increasing the reliability, precision and mechanical life thereof.</p> |
