Pre-setting method is:
Operating personnel rotate knob, and knob is without axial displacement;
Screw rod is rotation around the shaft under the drive of knob, and screw rod is without axial displacement;
Nut on screw rod is subject to inserting the restriction of the groove screw in slotted eye, only produces axial displacement, and corresponding variation also occurs the torque value that groove screw is indicated on the first moment of torsion scale; Meanwhile, stage clip is subject to the extruding of the flange face of nut, produce deformation quantity, cause the variation of the pressure of pressure ring to rotation steel ball, because the teeth groove of fixed disk has certain radian and is less than 180 degree, also there is corresponding variation in the required moment of torsion of teeth groove that therefore now rotates steel ball disengagement fixed disk.
Now, the torque value that groove screw is indicated on the first moment of torsion scale is the moment of torsion of torque spanner.
Initialization process is simple.
(2), the course of work
Operating personnel apply when the torque spanner of preset torque has carried out terminal operation, when the torque value bearing when wrenching bar reaches preset moment of torsion, rotation steel ball in the axial cylindrical hole of rotating disk is thrown off the teeth groove of fixed disk, cause that spanner handle drives fixed disk to rotate and rotating shaft and wrenching bar static (being spanner idle running), tightening torque is precisely controlled to preset moment of torsion reliably, reaches the object of controlling tightening torque.
After idle running, be rotated further spanner handle, can make to rotate steel ball and again playback and teeth groove and the axial tangent state of cylindrical hole.
