Description
technical field [0001] The invention relates to the field of automatic screwdrivers, in particular to a screwdriver for automatically adjusting pretightening force. Background technique [0002] Industrial assembly often uses electric or pneumatic screwdrivers. The existing screwdrivers can only simply achieve forward and reverse rotation. For occasions that need to control torque and pre-tightening force, it is often necessary to manually rely on traditional wrenches to tighten, which is inefficient and inaccurate. It is inconvenient to use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a screwdriver for automatically adjusting the pretightening force, which is powered by pneumatic or electric means; the pretightening force is fed back through the sensor and the control board to realize precise control; when the set force is reached, an additional rotation of 90 It has the advantages of high reliability, aut...
