Description
Technical field
The ridge that the present invention relates to the bolts such as stud that use in the foundation bolt that in building site for example, uses or the automobile etc. deform or the situation of corrosion etc. under the ridge of bolt is modified to the tool for correcting screw thread of standard shape, even can be reliably and carry out the tool for correcting screw thread that the correction of bolt thread tooth and long bolt also can begin to carry out the ridge correction from the middle part branch of bolt well even particularly relate in narrow place also.
Background technology
In general, at operation fields such as building site or garages, the ridge distortion of the stud that uses in foundation bolt in being driven into concrete or the automobile etc. etc. or corrosion etc. and can not use under the situation of bolt, perhaps on the ridge of bolt, adhere to foreign matter such as coating or concrete and can not use under the situation of bolt, use known in the past screw die and screw die retainer (diagram is omitted) to carry out the ridge correction of bolt.
Promptly, using screw die and screw die retainer to carry out under the situation of ridge correction of bolt, screw die is fixed on the screw die retainer, the cutting edge of screw die is pushed against on the end of the bolt that will revise, make the whole rotation of screw die retainer holding two bar-shaped handles that are located on the screw die retainer under this state, screw die and screw die retainer are moved successively along bolt.Like this, when the retouch of screw die by retainer, the function by screw die with the distortion of bolt ridge and corrosion ridge be modified to the shape of standard.
But, the ridge correction of the bolt that use screw die and screw die retainer carry out is owing to must insert screw die, make screw die and screw die retainer move to the retouch of ridge along bolt from the end thread of bolt, so when revising long bolt, the ridge of Xiu Zhenging is in the position away from the bolt end if desired, then must make screw die and screw die retainer rotation tens, hundreds of time, have can not be at short notice simply and the problem of easily carrying out the correction of ridge.And, under the situation that the ridge that needs correction is arranged on the end of bolt, be difficult to make ridge consistent, thereby can not revise the problem of the ridge of bolt in addition exactly with the phase place of the ridge of the bolt bottom that normally forms originally by the new bolt end that forms of screw die.
And then the screw die retainer is that the diametric(al) of middle mind-set screw die disposes two bar-shaped handles with a linearity with screw die, so need bigger radius of turn when the ridge correction operation of bolt.As a result, there is the narrow place that barrier is arranged in the radius of turn of handle can not carry out the problem of the ridge correction operation of bolt.
On the other hand, in this field, developed the utensil of the ridge that can begin to revise bolt, as the real flat 1-92324 communique open (patent documentation 1) of opening of Japan from the middle part branch of bolt in the past.
Promptly, above-mentioned utensil 20 (below be called ridge corrector 20) as shown in figure 12, comprising: a part is intersected and a pair of half member 22,22 that cross section is linked freely by axial region 21 rotations, respectively be located at a side of halved body parts 22,22 and be the shape that screw die two is cut apart the screw die halfbody 22a of portion, 22a, be located at halved body parts 22,22 opposite side handles halves 22b, 22b and be located between two handles halves 22b, the 22b and the two screw die halfbody 22a of portion, 22a can be fixed on fixed mechanism portion 23 under the closed state.
So, stating ridge corrector 20 in the use revises under the situation of ridge of bolts (diagram is omitted), at first operate fixed mechanism portion 23 and with the two screw die halfbody 22a of portion, the stationary state of 22a is removed, with two handles halves 22b, 22b is to extending out out and with the two screw die halfbody 22a of portion, 22a opens. then, the part (part that does not deform on ridge) of the bolt that will revise is inserted into the two screw die halfbody 22a of portion, between the 22a, and with two handles halves 22b, 22b is closed and by being formed on the two screw die halfbody 22a of portion, screw die tooth 22c on the 22a, the ridge of 22c grip bolt, in this state portion of mechanism 23 and of fixing of finishing drilling with the two screw die halfbody 22a of portion, 22a is fixed under the closed state. then, grasp two handles halves 22b, 22b, making ridge corrector 20 integral body is the center rotation with the bolt. like this, and by the two screw die halfbody 22a of portion, the screw die tooth 22c of 22a, the ridge that 22c will be out of shape is modified to the shape of standard.
In this ridge corrector 20, the two screw die halfbody 22a of portion, 22a with screw die function are structure to be opened/closed, so even can bring into play this excellent effect of ridge that begins also can revise bolt from the middle part of bolt.
But, in the above-mentioned ridge corrector 20,, when the ridge correction operation of bolt, need bigger radius of turn owing to have long bar- shaped handles halves 22b, 22b equally with the screw die retainer that is provided with two bar-shaped handles.As a result, there is the narrow place that barrier is arranged in the radius of turn of handles halves 22b, 22b can not carry out the problem of the ridge correction operation of bolt.
In addition, in this ridge corrector 20, the screw die halfbody 22a of portion, 22a with screw die function are located at a side of half member 22,22 integratedly, so under the situation of revising different bolt such as the diameter of bolt or thread pitch, can not use identical ridge corrector 20.The result, this ridge corrector 20 need be prepared the different multiple a plurality of ridge correctors 20 of size of the screw die halfbody 22a of portion, 22a corresponding to the diameter of the bolt that will revise and the pitch of screw thread etc., has to cause surging and keeping of cost and carrying also to be difficult to the problem of carrying out.And, under situations such as the screw die tooth 22c of the screw die halfbody 22a of portion, 22a, 22c damage, ridge corrector 20 must be abandoned self, the also relatively poor problem of economy is arranged.
And then, in this ridge corrector 20, carry out the two screw die halfbody 22a of portion, the fixed mechanism portion 23 fixing and that remove of 22a is located at a fixed axis 23a on the handles halves 22b freely by rotation, the hold-down nut 23b that is threadedly engaged with bolt part on the terminal part that is located at fixed axis 23a, and be formed on formations such as grooving 23c on another handles halves 22b, so carrying out the two screw die halfbody 22a of portion, 22a's is fixing, during releasing, hold-down nut 23b etc. need be unclamped and fixed axis 23a is extracted from the grooving 23c that is formed on the handles halves 22b, perhaps fixed axis 23a is inserted among the grooving 23c of handles halves 22b and fastening with hold-down nut 23b.As a result, this ridge corrector 20 the two screw die halfbody 22a of portion, 22a fixing, remove and spend time, the problem that can not promptly carry out the ridge correction of bolt is arranged.Particularly, under the more situation of the radical of the bolt that will revise, it is more remarkable that the problems referred to above become.
