Unclamp the stop screw 21b of adjusting nut 21, when adjusting nut 21 is turned right, the elastic force of spring (spring load) strengthens, when turning left, the elastic force of spring dies down.
In addition, only spring load is preferably determined by 2～3 examination processing.
As a result, when being screwed into adjusting nut 21, guide finger 16b forwards (among the figure left side) is mobile, make 16 deflections of the 2nd helical spring, the elastic force of the 2nd helical spring 16 is from guide 16a, by thrust bearing 24 pushing wheel hubs 9, and then push movable wheel 12, make the power grow of clamping ball 13.
Fig. 2 is the schematic diagram of moment of torsion shift transformation mechanism, and Fig. 2 (a) is the moving direction Y of the rotation direction N that rotates of stereogram and expression movable wheel, ball and the movable wheel polar plot at the direction of displacement Z of axial displacement.Shown in Fig. 2 (a), the moment of torsion shift transformation T of mechanism is made of fast pulley 11, movable wheel 12 and a plurality of ball 13.This moment of torsion shift transformation T of mechanism by by the fixing fast pulley 11 of handle of a knife 3 (with reference to Fig. 1), towards the movable movable wheel 12 of the direction of meet at right angles with axle (X) and for example 3 balls 13 constitute.
On movable wheel 12, the same groove 12a that on the end face of fast pulley 11 sides, forms 3 alms bowl shapes.And in the gap that the groove 12a by the groove 11a of said fixing wheel 11 and movable wheel 12 forms, also clamping is installed respectively ball 13.
Fig. 2 (b) be H before the expression action, shown in Fig. 2 (a) to the side view of looking, Fig. 2 (c) is the profile of I-I line shown in Fig. 2 (b).
Shown in Fig. 2 (c), ball 13 inserts and is clamped among the groove 12a of alms bowl shape of the groove 11a of fast pulley 11 alms bowl shapes and movable wheel 12.Fast pulley 11 is w with the profile width dimensions of movable wheel 12.
Fig. 2 (d) be H after the expression action, shown in Fig. 2 (a) to the side view of looking, Fig. 2 (e) is the profile of J-J line shown in Fig. 2 (d).
Shown in Fig. 2 (e), when the rotatory force of roller 1 (with reference to Fig. 1) passed to head 5, head 5 overcame the elastic force of the 2nd helical spring 16, and movable wheel 12 is rotated x towards rotating (N) direction.So the ball 13 according to rotate at the inclination angle of groove 11a, the 12a of 120 ° alms bowl shapes moves (with reference to the polar plot of Fig. 2 (a)) to the Y direction.And to the moving of Y direction, movable wheel 12 moves (displacement) z quantity towards the Z direction by means of this ball 13.
At this moment, fast pulley 11 becomes w+z with the profile width dimensions of movable wheel 12.This is because this torque conversion becomes the cause of axial displacement, so, it is called the moment of torsion shift transformation T of mechanism.
Like this, by the outer peripheral face of roller 1 pushing workpiece (machined object) W, the counter-force of the pushing force of being born by roller 1 makes movable wheel 12 rotations with the load torque that rotatory force produces.By means of this rotation, the ball of the groove clamping of cone shape is rotated, load torque is transformed into axial displacement, thereby changes the elastic force of the 2nd helical spring 16.By means of the variation of this elastic force,, also can compensate automatically the processing diameter even there is bigger deviation in the size of preprocessing.
For example, be that diameter differs 0.3mm under the situation of φ 30.0mm and φ 30.3mm at the diameter of axle of preprocessing, the pushing force that roller 1 bears (load) also produces than big-difference.The load torque that the counter-force of this pushing force applies the rotation of workpiece also produces difference.And shown in Fig. 2 (e), the dislocation that this load torque makes movable wheel 12 produce size x towards the N direction by means of ball 13, makes movable wheel 12 obtain the displacement of size z to axle (Z) direction, forces 16 deflections of the 2nd helical spring.
As a result, by the deflection variation of the 2nd helical spring 16, change the elastic force of the 2nd helical spring 16, variation according to this elastic force, the head 5 that has taper part 5t that is connected on the wheel hub 9 is retreated, so, just become the amount that big direction compensates 0.3mm automatically to diameter.
That is, by means of being built-in with the moment of torsion shift transformation T of mechanism
1The compensation of diameter compensation mechanism E, even there is deviation in the preprocessing size, carry out rolling and processing on one side on diametric(al) Yi Bian Barreling tool also can compensate automatically.Along with the change of load torque, load torque diminishes, when axial displacement obtains removing, and the Barreling tool homing, the position when non-loaded can not change.
Then, with reference to Fig. 1 action is described.
Shown in Fig. 1 (b), the initial setting of the cutter of Barreling tool 10 is described.At first, the initial setting of tool diameter is performed such, unclamp lock nut 23, adjustable ring 22 is retreated, the recess 8d of releasing housing 8 engages with the protuberance 22c's of adjustable ring 22, for the lower limit of the adjusting range of setting tool diameter, adjust to degree than the little 0.05～0.10mm of minimum diameter of work φ D.
Then, carry out the initial setting of elastic force.This Barreling tool 10 is controlled the diameter of cutter automatically by means of the elastic force (spring load) of the 2nd helical spring 16.This elastic force is set optimum value for corresponding to material, hardness, processing diameter and the surface roughness of workpiece.For this reason, unclamp the stop screw 21b of adjusting nut 21, when adjusting nut 21 was turned right, elastic force strengthened, and when turning left, elastic force weakens.
The rolling and processing of Barreling tool 10 is to roll processing by what roller 1 carried out, and external diameter only dwindles the amount that is rolled.Therefore, when in given tolerance dimension, polishing, preferably consider the reduction volume of external diameter in advance.For example, about φ 30mm, should consider that reduction volume is 0.02～0.04mm.
Here, Barreling tool 10 is fixed on the knife rest of NC lathe, makes workpiece with rotating speed 600min
-1Rotate.And, workpiece W insertion has been disposed in the cylindric support 2 of a plurality of rollers 1.So roller 1 contacts with the workpiece machined surface, to the pressurization of the machined surface of workpiece W, roll the machined surface of (plastic deformation) workpiece W, whereby, the surface finish of machined surface is become smooth minute surface.
To the foregoing summarizing as can be known, diameter compensation mechanism E
1By means of the above-mentioned moment of torsion shift transformation T of mechanism
1The axial displacement that produces changes the elastic force of the 2nd helical spring 16, makes the head 5 that is connected with wheel hub 9 mobile vertically, even there is deviation in the preprocessing size, also can process the automatic compensation of diameter.
For example, even there is deviation in the preprocessing diameter of workpiece, by means of being built-in with the moment of torsion shift transformation T of mechanism
1Diameter compensation mechanism E
1, according to the preprocessing diameter of workpiece, change the axial location of roller 1, change tool diameter automatically.
That is to say that when inserting Barreling tool 10 in the smaller workpiece of preprocessing diameter, the elastic force of the 2nd helical spring 16 overcomes polish pressure, makes wheel hub 9 move to the cutter front, tool diameter diminishes automatically.But it can be less than the tool diameter that sets in advance.
In contrast, when inserting Barreling tool 10 among the bigger workpiece W of preprocessing diameters, polish pressure overcomes the elastic force of the 2nd helical spring 16, makes wheel hub 9 move to handle of a knife 3 sides, and tool diameter can become big automatically.
