Technical field
The present invention relates to technology with the step-up system vise, at length be, relate to having and push by main body frame restriction rotation by lead screw shaft and utilize in the step-up system of the moveable jaws that the axis direction that is rotated in lead screw shaft of the lead screw shaft that cooperates moves, by adjusting the pressure of step-up system, adjust the technology of clamping force of the workpiece of be fixed jaw and moveable jaws clamping to lead screw shaft.
Background technology
The vise that possesses step-up system can obtain firm workpiece clamping force.In the communique of patent documentation 1, on vise, be provided with mechanical step-up system, this step-up system is configured in the distolateral of lead screw shaft, by rotating but can not be with moving axially, promptly can not rotate relatively but can center on with axially relatively moving at the hollow shaft that cooperates with lead screw shaft at the hollow shaft that is supported on main body frame.Step-up system possesses: have the lead screw shaft side end of cone shape and at axially extended working shaft; Have through hole that inserts working shaft and the working shaft support component that is supported by hollow shaft with the state that restrictive axial relatively moves; With with respect to the axis of working shaft configuration symmetrically and 4 rollers contacting with the lead screw shaft side end of cone shape by twos, between an end and working shaft support component of lead screw shaft, formed the roller accommodation space.The axial length of this accommodation space is for leaving axis, promptly short more more in the outer part more.Lead screw shaft can not be rotated relatively but can cooperated with hollow shaft with axially relatively moving, and the rotation of the rotation cardan shaft that is rotated by handle or motor etc. passes to hollow shaft by arrangement of clutch, the lead screw shaft rotation that then can not cooperate with hollow shaft with the relative rotation.Along with the rotation of lead screw shaft, moveable jaws is moving axially along the slide-and-guide face of main body frame, moves to regular jaw.Begin with regular jaw and moveable jaws holding workpiece,,, make lead screw shaft rotate necessary power again and surpass the rotation transmission capacity of arrangement of clutch to the transmission of hollow shaft in order to obtain sufficient clamping force when workpiece clamping force greatly to a certain degree the time.That is, the rotation transmission of arrangement of clutch is disengaged.Therefore, hollow shaft no longer rotates, promptly just rotates the cardan shaft rotation along with the rotation of rotation cardan shaft.Therefore, the rotation cardan shaft stops the rotation along with hollow shaft and rotates relatively with respect to hollow shaft, but since hollow shaft on main body frame, be limited axial move and with rotation cardan shaft threaded engagement, so the rotation cardan shaft is at the working shaft that moves axially and push step-up system.Working shaft is pushed an end of lead screw shaft to increase with the wedge effect by the power of the pressing force of the rotation cardan shaft of drivings such as handle by 4 rollers.The driving torque of the handle of driving rotation cardan shaft etc. becomes big, and in axial moving, each roller moves to radial outside at the roller accommodation space working shaft thereupon to lead screw shaft one end.As mentioned above, because the axial length of roller accommodation space is short more by radial outside more, so the radial outside of roller accommodation space has partly been taken in roller, promptly, in order to allow the moving to radial outside of roller, one end of lead screw shaft must be axially to moving with the working shaft opposition side, and lead screw shaft moves, and the moveable jaws that cooperates with lead screw shaft moves to regular jaw.Therefore, the driving torque of swelled handle etc. then strengthens and pushes the pressing force of lead screw shaft, and the working shaft of step-up system then can obtain strong more workpiece clamping force with respect to hollow shaft, promptly move to the direction near lead screw shaft vertically more with respect to main body frame.
In the communique of patent documentation 2, the step-up system of fluid pressure type is set on vise, this step-up system is provided in the distolateral of lead screw shaft, is centered on by the hollow shaft identical with the mechanical type step-up system.Step-up system possesses: the working shaft of Yan Shening vertically; With through hole, and, between an end and working shaft support component of lead screw shaft, form the hydraulic pressure chamber of having filled action liquid with the working shaft support component that the state that restrictive axial relatively moves is supported by hollow shaft with insertion working shaft.Begin holding workpiece with regular jaw and moveable jaws, when the workpiece clamping force reaches to a certain degree, remove the rotation transmission of arrangement of clutch, to increase device the same with mechanical type, and the rotation cardan shaft is moving axially, and pushes the working shaft of step-up system.At hydraulic pressure chamber because the sectional area of an end of lead screw shaft big more than working shaft so can have more than by rotating the also big power of power that cardan shaft is pushed working shaft with driving such as handles by hydraulic pressure, pushed an end of lead screw shaft.Therefore the moveable jaws that moves by lead screw shaft and cooperate with lead screw shaft moves towards regular jaw.Thereby the same with the mechanical type step-up system, by the driving torque of swelled handle etc., the working shaft of step-up system is axially moving to the direction near lead screw shaft more, can obtain firm workpiece clamping force more.
Must workpiece be remained on the vise with suitable clamping force.For example, when the workpiece of the low material of processing thin-walled parts or rigidity such as aluminium, plastics, because of excessive clamping force workpiece can be out of shape.Recover after process finishing owing to strain, or impair machining accuracy, or impair quality because of the plastic deformation product is out of shape.In addition, when clamping force was too small, sometimes because of the operating force workpiece produces skew, or generation processing was bad on the contrary, or because of situation cutter generation damage.In order to adjust clamping force, keep workpiece with suitable clamping force, in the communique of patent documentation 3, on the vise that possesses the mechanical type step-up system, be provided with the clamping force adjusting device.
Constitute hollow shaft by lead screw shaft side hollow shaft that is separated from each other and lead screw shaft opposition side hollow shaft, make lead screw shaft side hollow shaft and rotation cardan shaft threaded engagement, and can not rotate relatively but can cooperate with an end of lead screw shaft with axially relatively moving, in addition, by arrangement of clutch lead screw shaft opposition side hollow shaft is connected with the rotation cardan shaft, the rotation of rotation cardan shaft is delivered to lead screw shaft opposition side hollow shaft by arrangement of clutch.End face by being located at lead screw shaft side hollow shaft and the guide finger that extends vertically can not rotate but can be at axially cooperation lead screw shaft side hollow shaft and lead screw shaft opposition side hollow shaft relatively with relatively moving.Between two hollow shafts, be provided with the baffle ring that has towards the outstanding protuberance of lead screw shaft direction, by above-mentioned guide finger, can not cooperate with two hollow shafts with the relative rotation.On lead screw shaft opposition side hollow shaft, be provided with and adjust ring, and can remove with lead screw shaft opposition side hollow shaft and keep adjustment to encircle ordinatedly.Baffle ring is provided with external screw thread on outer peripheral face, and be located at the internal thread threaded engagement of adjusting on the ring, for baffle ring, by adjust ring limited relative lead screw shaft opposition side hollow shaft in axial relatively moving.In addition, the mid portion formation stage portion at the rotation cardan shaft in the lead screw shaft side end face of this stage portion, is provided with the rotation propulsive element that has to the outstanding protuberance of lead screw shaft direction.The protuberance of rotation propulsive element is after releasing is transmitted in the rotation of arrangement of clutch, along with rotation of rotating cardan shaft and axial moving cooperate with the protuberance of baffle ring.Thus, the rotation cardan shaft can not rotate relatively with respect to lead screw shaft side hollow shaft.By along with the step-up system that advances of rotation cardan shaft to the pushing of working shaft, just workpiece is applied bigger clamping force, therefore, with because of from the bigger reaction force of workpiece that produce with frictional force main body frame, limit the rotation of lead screw shaft side hollow shaft.Therefore, the rotation cardan shaft stops because of the rotation of handle etc., keeps workpiece with the clamping force of regulation.The adjustment of workpiece clamping force is adjusted ring and is rotated and baffle ring is carried out moving axially by remove adjusting cooperating of ring and lead screw shaft opposition side hollow shaft, making.That is,, reduce clamping force, leave, strengthen clamping force by making baffle ring by making baffle ring close with respect to the rotation propulsive element.

In addition, baffle ring can not relatively rotate (scheme 2) by from the outstanding counterrotating fixed part that limits baffle ring and hollow shaft of the outer peripheral face of hollow shaft with main body frame.
Further, the outer peripheral face of baffle ring is relative with the inner peripheral surface of main body frame, the detent mechanism at above-mentioned axial location of restriction baffle ring is set, this detent mechanism possesses recess and possesses protuberance the opposing party a side of above-mentioned outer peripheral face and above-mentioned inner peripheral surface, and the side in recess and the protuberance above-mentioned axially set a plurality of, the opposing party can move and selectively cooperates with any of a side by being made as towards a side, thus can adjust baffle ring and main body frame in above-mentioned axial relative position (scheme 3).
In addition, above-mentioned the opposing party of recess and protuberance is by being applied in elastic acting force and can cooperating (scheme 4) with a side towards a side.
In addition, on the above-mentioned outer peripheral face of baffle ring, axially set a plurality of recesses above-mentioned, and form recess and insert component on main body frame, thereby protuberance is set on main body frame, component is by being applied in elastic acting force and can cooperating (scheme 5) with recess towards recess.
In addition, baffle ring has at the above-mentioned lead screw shaft opposition side annulus that exposes from the lead screw shaft opposition side of main body frame that extends axially, the rotation propulsive element has the lead screw shaft side annulus that axially extends to the lead screw shaft side above-mentioned, this lead screw shaft side annulus inserts in the above-mentioned lead screw shaft opposition side annulus, and has above-mentioned protuberance (scheme 6).
In addition, on the outer peripheral face of the lead screw shaft side annulus that rotates propulsive element, be provided with circumferential groove (scheme 7).
In addition, above-mentioned circumferential groove is provided with many, and with corresponding respectively the setting of a side (scheme 8) at above-mentioned a plurality of recess that axially sets and protuberance.
With rotation rotation cardan shafts such as handles, by the moving hollow shaft of arrangement of clutch rotation, lead screw shaft is rotated because of the rotation of hollow shaft, and moveable jaws axially moves towards regular jaw lead screw shaft, begins the fastening of workpiece.Clamping force strengthens, and it is big that the rotational resistance of hollow shaft becomes, and when surpassing the rotation transmission capacity of arrangement of clutch, then the rotation transmission of arrangement of clutch is disengaged.Along with the rotation of arrangement of clutch is transmitted and removed, the rotation cardan shaft is relative with hollow shaft to be rotated and the moving axially of lead screw shaft, simultaneously will be corresponding to the working shaft that brings step-up system because of the pressing force with the revolving force of hollow shaft threaded engagement generation.According to scheme 1, with regard to the rotation cardan shaft, be provided with the rotation propulsive element that can cooperate with baffle ring moving axially along with while rotating, baffle ring can not rotate relatively with main body frame, so the rotation cardan shaft stops the rotation that is produced of handle etc. by baffle ring, with the clamping force maintenance workpiece at axial relative position corresponding to baffle ring and main body frame.Since can adjust baffle ring and main body frame at relative axial position, so can be with desirable clamping force maintenance workpiece.And, owing to insert hollow shaft in the baffle ring, so the ledge of the ledge of baffle ring, rotation propulsive element is radially than the outer peripheral face of hollow shaft more in the outer part, away from the pivot of rotation cardan shaft, the impulsive force of moment, the impulsive force that applied when promptly stoping the rotation of rotation cardan shaft are less so two ledges cooperatively interact.Therefore, the clamping force adjusting device can suppress baffle ring and rotation propulsive element because of breakage, distortion or wearing and tearing that impulsive force caused.
When strengthening the clamping force of workpiece, the rotation transmission of arrangement of clutch is disengaged, thereby hollow shaft can not relatively rotate with main body frame because of the rotation cardan shaft can't rotate.Under state in relative rotation, increase the clamping force of workpiece, the reaction force of clamping force is increased, hollow shaft and main body frame are by keeping axially pushing the frictional force that is produced because of mutual, and the big more frictional force of clamping force is big more, and is firm more.According to scheme 2, be provided with from the outstanding fixed part of hollow shaft outer peripheral face the relative rotation of this component limitations baffle ring and hollow shaft.At length be that fixed part is supported by the radial outside part of hollow shaft and a radially inner side side partly of baffle ring, and inserts and be located in the opposing party's the axial groove.Baffle ring can not rotate with main body frame relatively by being in and hollow shaft under main body frame can not relative rotation status, has stoped the rotation of rotation cardan shaft.Therefore, baffle ring and hollow shaft limit relative rotation between them by fixed part, do not take on the cross sectional shape of side face, part or all to be made the tabular surface that is in contact with one another and limit counterrotating method,, make easily so can adopt circular cross-section.As mentioned above, because hollow shaft can not rotate with main body frame relatively because of frictional force, when stoping the rotation of rotation cardan shaft by baffle ring, energy overcome friction and rotating.Therefore, relaxed the impulsive force that baffle ring, rotation propulsive element and fixed part are applied, suppressed damaged or distortion.In addition, adjust by hollow shaft baffle ring and main body frame at axial relative position, and till the rotation of having removed arrangement of clutch was transmitted, baffle ring rotated with rotation propulsive element one.Therefore, because of varying in size of workpiece, even the quill shaft when removing arrangement of clutch rotation transmission is with respect to the rotatable phase difference of main body frame, after releasing is transmitted in the arrangement of clutch rotation, up to the rotation amount of the rotation cardan shaft of two ledges till cooperatively interacting of baffle ring and rotation propulsive element, be that the amount of movement of the working shaft of step-up system also is roughly necessarily, can correctly obtain the workpiece clamping force of stipulating.
According to scheme 3, corresponding to the side at a plurality of recesses that axially set and protuberance, baffle ring axially is being positioned at a plurality of positions with respect to main body frame.Therefore, the clamping force adjusting device can improve the repeatability of clamping force, even because of the essential change of change workpiece clamping force, also can easily obtain correct clamping force.
According to scheme 4, above-mentioned the opposing party of recess and protuberance overcomes active force and moves when applying power, thereby releasing cooperates with a side's, move when removing the Li Shiyin active force, cooperate with a side once more, owing to cooperate with a side and remove and the cooperating an of side, thus do not need to move with instruments such as spanners, can be easily and promptly adjust the clamping force of workpiece.
According to scheme 5, component does not need special shape, can use cheap parts such as steel ball or conical part.
According to scheme 6, hollow shaft and rotation cardan shaft are surrounded by two annulus, can suppress entering of smear metal powder, cutting fluid etc.Further, can catch and touch lead screw shaft opposition side annulus baffle ring is moved, can easily adjust the clamping force of workpiece.
According to scheme 7, according to the established part of the lead screw shaft opposition side annulus of baffle ring, the end of for example lead screw shaft opposition side annulus and the position relation of circumferential groove, the axial location of baffle ring can be learnt, thereby the adjustment situation of clamping force can be confirmed with respect to main body frame.And, be accompanied by the increase of clamping force, the position relation axial of the established part of lead screw shaft opposition side annulus and circumferential groove also changes, by observation to this position relationship change, before clamping force reaches setting, can make rotary speed reduction by the rotation cardan shaft of generations such as handle.Therefore, can promptly carry out the maintenance operation of workpiece, reduce impulsive force simultaneously, thereby can suppress the damaged or distortion of the fixed part of baffle ring, rotation propulsive element and baffle ring.
According to scheme 8, as long as the established part, for example end that make the lead screw shaft opposition side annulus of baffle ring are for example consistent with the position relation axial corresponding to the circumferential groove of clamping force, even change clamping force then also can easily be confirmed the adjustment situation of clamping force.Therefore, can eliminate the worry that mistake is adjusted to the clamping force beyond wishing.

In addition, vise 100 possesses clamping force adjusting device 110, and this clamping force adjusting device 110 possesses: with the outer peripheral face of hollow shaft 14 chimeric, promptly insert the baffle ring 40 of hollow shaft 14; Extend vertically and be fixed on the hollow shaft 14 and from the outstanding key 48 of the outer peripheral face of hollow shaft 14; And be fixed on the lead screw shaft opposite ends of rotation cardan shaft 15 by hexagon socket head cap screw 34, and have vertically the rotation propulsive element 41 of the lead screw shaft side annulus 41a that extends simultaneously, on the inner peripheral surface of baffle ring 40, formed the keyway that guides key 48 vertically.
Detent mechanism 111 has: adjust ring 42; Be located at the pin of adjusting on the ring 42 47; Steel ball 43; And be located at pin 46 on the main body frame 3b.
The pin 46 that is located on the main body frame 3b is radially extending, be located at the outer peripheral face of adjusting ring 42 on and cooperate at axially extended groove 42b.With the phase difference that become regulation with pin 46, if describe in detail is to be the phase difference of the regulation at center, to be 180 ° phase difference in the present embodiment with axis 10a, steel ball 43 insertions are located in the screwed hole of main body frame 3b, and to radially inner side it is applied elastic acting force with compression helical spring 44, simultaneously by adjusting the amount of the being screwed into corrective action power of hexagon socket head cap screw 45.The outer peripheral face of adjustment ring 42 and baffle ring 40 and the inner peripheral surface of main body frame 3b are chimeric, extending axially simultaneously, lead screw shaft opposition side annulus 42a is outstanding from main body frame 3b and baffle ring 40, and inserts the outer peripheral face of the lead screw shaft side annulus 41a of rotation propulsive element 41.On the outer peripheral face of adjusting ring 42, except groove 42b, also poor with the prescribed phases that is become with groove 42b, promptly with main body frame 3b on the pin 46 and the phase difference of screwed hole be to be 180 ° phase difference in identical phase difference, the present embodiment, form conical bore 42c, disposed 4 this conical bore 42c simultaneously vertically side by side.Therefore, conical bore 42c and formed recess and protuberance respectively and cooperatively interact by the steel ball 43 that compression helical spring 44 applies the power of acting on.Being located at the pin 47 adjusted on the ring 42 is radially extending and is cooperating with circumferential groove 40e on the outer peripheral face of being located at baffle ring 40.With this, can rotate relatively but can not make baffle ring 40 with moving axially relatively and adjust ring 42 and cooperate.Therefore, baffle ring 40 and adjustment ring 42 become the baffle ring that is made of shape counterrotating two parts of energy, have constituted and have asked for protection the baffle ring described in the scope.
Below, the maintenance operation of the workpiece 2 on the vise 100 is described.As shown in Figure 1, workpiece 2 is positioned between regular jaw 5 and the moveable jaws 6, with the not shown handle that is installed on the hexagonal handle mating holes 15a, and rotation rotation cardan shaft 15.The rotation of rotation cardan shaft 15 passes to hollow shaft 14 by arrangement of clutch 70, by being fixed on the lead screw shaft 10 that 13 rotations of hexagonal through hole bolt can not cooperate with hollow shaft 14 with the relative rotation in the band on the hollow shaft 14.By the rotation of lead screw shaft 10, mobile vertically with the nut 9 of lead screw shaft 10 threaded engagement, the moveable jaws 6 that is fixed on the nut 9 follows sliding closure 4 to move, as shown in Figure 2, and the clamping of beginning workpiece 2.
Then if strengthen the clamping force of workpiece 2, make moveable jaws 6 move again required lead screw shaft 10 revolving force, be the rotational resistance of hollow shaft 14 when surpassing the rotary transfer force of arrangement of clutch 70, the fitting projection of clutch ring 21 skids off from the mating groove of nut 20.That is, removed the rotation transmission of arrangement of clutch 70, hollow shaft 14, lead screw shaft 10 are no longer rotated.When the rotation of removing arrangement of clutch 70 is transmitted, have only 15 rotations of rotation cardan shaft, rotation cardan shaft 15 relatively moves with respect to hollow shaft 14 vertically.With the lead screw shaft opposition side end of the working shaft 16 of rotation cardan shaft 15 adjacency, chimeric have a bearing block 25, the bearing block 24 of lead screw shaft side end that is fixed on rotation cardan shaft 15 is pushed working shaft 16 by sliding bearing 30 and bearing block 25 to the lead screw shaft side.The pressing force that puts on working shaft 16 is increased because of the wedge effect of the lead screw shaft side end 16a of cone shape, by 4 rollers 17,18, pushes the end axis 11 that is fixed on lead screw shaft 10 1 ends.Lead screw shaft 10 is axially being pushed, and by the nut 9 of threaded engagement, moveable jaws 6 is pushed to the direction of regular jaw 5.
Along with the pressing force of the rotation cardan shaft 15 that is rotated by handle becomes big, working shaft 16 is to the lead screw shaft side shifting, and 4 rollers 17,18 move to radial outside.Because the roller accommodation space that is formed between end axis 11 and the working shaft support component 19 is more little by radial outside more, so along with 4 rollers 17,18 moving to radial outside, end axis 11 is moving axially, and workpiece 2 is remained on the vise 100 by bigger clamping force.
Along with moving axially of rotation cardan shaft 15, rotation propulsive element 41 is moving axially, as Fig. 3 and as Fig. 6 of the major part enlarged drawing of Fig. 3, shown in Figure 7, be located at the protuberance 40b on protuberance 41c and the lead screw shaft opposite sides 40a that is located at baffle ring 40 on the lead screw shaft side 41b of lead screw shaft side annulus 41a, its mating surface 40c, 41d are fitted to each other, and rotation cardan shaft 15 can not rotate.Promptly, the key 48 of baffle ring 40 by being provided with as fixed part, limited relative rotation with respect to hollow shaft 14, hollow shaft 14 is pushed main body frame 3b by thrust bearing 33 to the lead screw shaft opposition side by result from the reaction force from workpiece 2 on the lead screw shaft 10 along with pushing of 10 pairs of workpiece 2 of lead screw shaft.Because this is pushed, and produces frictional force between hollow shaft 14 and main body frame 3b, big more this frictional force of pressing force is big more, promptly increases the clamping force of workpiece 2 more, just can stop the relative rotation of hollow shaft 14 with respect to main body frame 3b more.Since when rotation cardan shaft 15 moves, mating surface 40c, when 41d is fitted to each other, and the clamping force of workpiece 2 reaches setting, so can stop the relative rotation of hollow shaft 14 with respect to main body frame 3b with sufficient frictional force.Therefore rotate cardan shaft 15 because of being difficult to be rotated moving stopping by handle.
The clamping force adjustment of workpiece 2 is adjusted that ring 42 slides and is realized moving axially by making.Because steel ball 43 is compressed helical spring 44 and has applied elastic acting force, so if adjustment ring 42 is being moved axially, then can overcome elastic force moves to radial outside, along with adjusting moving of ring 42, remove itself and the cooperating of conical bore 42c, thereby cooperate with other conical bores 42c that can obtain the regulation clamping force.In addition, the pin 46 of main body frame 3b cooperates with groove 42b, and the ring 42 relative rotations with respect to main body frame 3b are adjusted in restriction, and conical bore 42c and steel ball 43 positively cooperate.In addition, on the outer peripheral face of the flange portion 42d of lead screw shaft opposition side annulus 42a, be provided with annular knurl, can hand easily make non-skidly and adjust ring 42 and slide.
Along with adjusting moving of ring 42, to be located at the pin of adjusting on the ring 42 47 and to move axially, the baffle ring 40 that cooperates with pin 47 by circumferential groove 40e is also moving axially.With this, the protuberance 40b of baffle ring 40 axially with the protuberance 41c of the lead screw shaft side annulus 41a of rotation propulsive element 41 near or leave.As shown in Figure 8, when protuberance 40b adjusted to position near protuberance 41c, before reaching big clamping force, two protuberance 40b, 41c cooperated and the rotation of the cardan shaft 15 that stops the rotation.In addition, as shown in Figure 6, when protuberance 40b adjusted to the position of leaving protuberance 41c, after reaching big clamping force, two protuberance 40b, 41c cooperated and the rotation of the cardan shaft 15 that stops the rotation.Therefore, can workpiece 2 be remained on the vise 100 with the less clamping force of regulation or bigger clamping force.
Rotation propulsive element 41 is provided with many circumferential groove 41f on the outer peripheral face of lead screw shaft side annulus 41a, these many circumferential groove 41f are set to: the end face of the flange portion 42d of adjustment ring 42 is consistent with circumferential groove 41f, and corresponding at the conical bore 42c of axis direction and adjustment ring 42.In Fig. 6, steel ball 43 with from the lead screw shaft side of adjusting ring 42, promptly cooperate from the 4th conical bore 42c of left-hand digit, the end face of flange portion 42d is with consistent from the 4th circumferential groove 41f of right-hand component.In Fig. 8, steel ball 43 with cooperate from the 2nd conical bore 42c of left-hand digit, the end face of flange portion 42d is with consistent from the 2nd circumferential groove 41f of right-hand component.In addition, adjust to when cooperating with the conical bore 42c of the leftmost side when steel ball 43, the end face of flange portion 42d is consistent with the circumferential groove 41f of the rightmost side, but this moment, because protuberance 40b, 41c cooperate each other, so step-up system 80 is inoperative.Promptly, because hollow shaft 14 can not rotate with respect to main body frame 3b relatively because of frictional force, so hollow shaft 14 can rotate, rotate the rotary transfer force of being fitted to each other of back protuberance 40b, 41c and arrangement of clutch 70 by rotation cardan shaft 15, hollow shaft 14 is rotated, thereby lead screw shaft 10 is rotated.When the clamping force that strengthens workpiece 2, when the rotational resistance of hollow shaft 14 strengthens, be difficult to turning handle, the operator finishes the maintenance operation of workpiece.So do not keep workpiece 2 because step-up system 80 does not work with less clamping force, not the distortion that produces because of clamping force.
Along with the moving of rotation cardan shaft 15, promptly along with the increase of clamping force, the circumferential groove 41f of rotation propulsive element 41 advances to the lead screw shaft side vertically gradually, relatively moves with respect to the end face of the flange portion 42d that adjusts ring 42.In the present embodiment, as shown in Figure 6, under the state that rotation cardan shaft 15 stops after reaching the clamping force of regulation, be disposed at the circumferential groove 41f of the rightmost side and the end face of flange portion 42d, they are in axial position consistency.When protuberance 40b, 41c are fitted to each other, when the rotation of rotation cardan shaft 15 stops,, be applied with impulsive force for protuberance 40b, 41c and as the key 48 of the fixed part of baffle ring 40.The operator is according to the position relation of end face and the circumferential groove 41f of flange portion 42d, and clamping force approaches setting value as can be known, thereby can reduce the rotary speed of handle, reduces above-mentioned impulsive force.Therefore, except the breakage of the structure member that can suppress clamping force adjusting devices 110 such as protuberance 40b, 41c and key 48, distortion, can also accelerate the rotary speed of handle when the operation beginning, workpiece keeps operation thereby can carry out rapidly.
In addition, in the present embodiment, because the frictional force that hollow shaft 14 produces because of the reaction force based on the workpiece clamping force can not relatively rotate with respect to main body frame 3b, when protuberance 40b, 41c are fitted to each other, the rotation though hollow shaft 14 rotates less by overcome friction.Therefore, absorb the impulsive force that puts on protuberance 40b, 41c and the key 48 etc., can suppress breakage, the distortion of the structure member of clamping force adjusting device 110.
In the present embodiment, on adjustment ring 42, be provided with conical bore 42c, be recess, on main body frame 3b, be provided with steel ball 43, be protuberance, but also recess can be located on the main body frame 3b, protuberance is located at adjusts on the ring 42 simultaneously.
In addition, on hollow shaft 14, be provided with key 48, but pin also can be set as fixed part and make it outstanding on quill shaft 14, cooperate with the groove that extends vertically on being located at baffle ring 40 from outer peripheral face as the fixed part of baffle ring 40.
On the vise 100 of present embodiment, used mechanical type step-up system 80, and utilized the wedge effect of the lead screw shaft side end 16a of working shaft 16, but also can use fluid pressure type step-up system 90 as shown in Figure 9.
Fluid pressure type step-up system 90 is provided with the stage portion of radially inner side on the inner peripheral surface of the mid portion of hollow shaft 14, have: be supported on the working shaft 37 on this stage portion; Embedding also is fixed in the above-mentioned stage portion inner peripheral surface of hollow shaft 14 and the seal 38 that sealing surface contacts with working shaft 37; With the outer peripheral face that embeds and be fixed in the lead screw shaft opposition side end of end axis 11, the seal 39 that sealing surface contacts with the inner peripheral surface of hollow shaft 14, between the above-mentioned stage portion of the inner peripheral surface of hollow shaft 14 and end axis 11, form hydraulic pressure chamber, be filled with action liquid.The driving side sectional area of this hydraulic pressure chamber is the sectional area of working shaft 37, and being driven the lateral section long-pending is the sectional area of the inner peripheral surface of hollow shaft 14.
The rotation of arrangement of clutch 70 is transmitted and is removed, and rotation cardan shaft 15 is moving axially, and pushes working shaft 37.Since hydraulic pressure chamber be driven that the lateral section is long-pending to be far longer than the driving side sectional area, so end axis 11 has been applied in the power of the pressing force that is far longer than working shaft 37.Increase the revolving force of operator with handle, rotation cardan shaft 15 is moving axially, and along with the pressing force increase of working shaft 37, pushes end axis 11 more forcefully.Therefore, the same with mechanical step-up system 80, along with rotation cardan shaft 15 in axial moving, the workpiece clamping force increases, the protuberance 41c of rotation propulsive element 41 cooperates the rotation of the cardan shaft 15 that stops the rotation thus with the protuberance 40b's of baffle ring 40.Thereby the clamping force with regulation remains on workpiece 2 on the vise 100.
