The bombardment nut runner which has the measurement equipment and the aforementioned measurement equipment which measure the angular displacement of the output axis of the bombardment nut runner when fastening the screw coupling

摘要

Topic It fastens without using angular perception means on the output axis and it offers the bombardment nut runner which has the measurement equipment and the aforementioned measurement equipment where you can obtain the angular displacement of the output axis between.SolutionsThe bombardment nut runner, the housing 10 which possesses handle 11, throttle valve 12, pressure air introduction concatenated section has 13 and exhaust air opening 14. Furthermore, the nut runner, rotor the pneumatics type vane motor through 20 which possesses 21 and the fixed cylinder 22 and nut socket 26, has with the impulse unit 23 which possesses the output axis 24 in order to concatenate with threaded fastener 25. In addition, impulse unit 23 has the inertial Drive component 27 of the cylindrical shape, this inertial Drive component 27 is concatenated by the rotor 21 of the motor strongly, has the hydraulic fluid chamber 29 which is demarcated partly by the toe of switch wall 30.
