PRESSURE BOLT FASTENING DEVICE

摘要

A pressure bolt fastening device is provided to reduce working time by fastening bolts with the same torque simultaneously. A pressure bolt fastening device comprises a press contact unit(10), a holder main body(20), a bolt type fastening member holding unit(20a), a pressure actuator(30), and a control manifold unit(50). The press contact unit is in surface contact with the surface of an adjacent fastening member. The holder main body extends as long as the width between bolt type fastening members(B). The bolt type fastening member holding unit, having a nut type fastening member(N), is fixed to the end of the holder main body. The pressure actuator, which is fixed to the center of the holder main body and jointed to the press contact unit rotatably, fastens the nut type fastening member by pressing an intermediate contact member. The control manifold unit controls the pressure supplied to the pressure actuator.
