SU1752539A1 - Device for simultaneous tightening of securing members of annular flanges - Google Patents

Abstract

The invention relates to mechanical engineering and can be used to mechanize the tightening of threaded joints of annular flanges. The purpose of the invention is to improve the accuracy and convenience of tightening. When the device is operating, a fixed ring 1 is mounted on the flange 2, and the movable rings 3 and 4 on it are fixed by stops 7 and 8 against the fastening elements. On the latter, ratchet wrenches 10 and control devices 16 with ultrasonic transducers are installed. On command from the control unit, pneumatic cylinders 5 drive the rings 3 and 4, which transmit torque to the keys 10, which tighten the fastening elements. Pulling forces are compared and corrected by the microprocessor unit. 5 il.
