Process and a device for the rotation-angle-monitored tightening or loosening of screw connections |
摘要 |
The invention relates to a process and a device for the rotation-angle-monitored tightening or loosening of screw connections by means of power driven tools. The absolute rotation angle swept over in the screwing operation with respect to a fixed point about a swivel axis through the rotation axis of the screw connection is measured. An advantageous, relative-position free, absolute measurement of the rotation angle is effected by the use of an absolute rotation-rate measuring sensor. The rotation-rate sensor can herein be configured as a mechanical, compass-like gyroscope, as a rotation sensor or as an acceleration sensor, by means of which a measured value correlated with the absolute rotation angle can be recorded.
