Tool for setting threaded rivet nuts with pressure medium driven rotary motor

摘要

For turning the threaded rivet nut, the motor rotates the tool threaded spindle (5) to the right. The upsetting is actuated by a pressure medium drive pusher, actuating the threaded spindle axial movement for upsetting. A change-over valve (8) forms a control for the pressure medium. Under the valve action, the motor rotates to the left, while the spindle, the pusher, the motor, and the valve are interconnected axially. The drive is formed by a hydraulic-pneumatic unit. Onto the gripper housing (10) end (11) with an adjusting thread (35) is fitted a stop sleeve (9), limiting the axial motion of the spindle and retaining the change-over valve.
