Magnetic screwdriving and insertion system with manipulation which can be rendered automatic

摘要

In the magnetic screwdriving and insertion system with manipulation which can be rendered automatic, screws which have no longitudinal or cross-wise recesses and nuts which have no bevels accessible from outside are turned by means of a screwdriving head, driven electrically by manual actuation, by virtue of the fact that the spindles located in the screwdriving head are pressed into the channels located in the screw, the nut, etc., and then the screwdriving head is turned, in the course of which the spindles - controlled by magnets - automatically search for the channels. The nuts can therefore be let into the body in a completely flush position. Optical uniformity of the surface of the workpiece is obtained by covering the channel openings by magnetic lenses. Magnetic bodies controlled by the screwdriving head ensure that a push-in fastener, also designed as an electric socket, can be locked in a threadless holder, in which case the holder itself can also be anchored in a body if the opening available is slightly too large. In the case of greater clearance space, a screw provided with a spring is used. All operations relevant to the control of the working sequence are indicated by signals so that the system is also suitable for automatic manipulating devices.
