(the first execution mode)

First, illustrate that the twin shaft of embodiment of the present invention exports servo motor 150A.Fig. 1 is the end view that twin shaft exports servo motor 150A.Twin shaft exports the ultralow inertia servo motor that servo motor 150A is height output (specified output 37kW) possessing two output shafts 150A2a, 150A2b.Twin shaft exports servo motor 150A and possesses body frame 150A1, driving shaft 150A2, the first bracket 150A3 and the second bracket 150A4.

Body frame 150A1 is roughly cylindric framework, and within it week is provided with the stator (not shown) with coil.At the direction of principal axis both ends of body frame 150A1, be separately installed with the first bracket 150A3 and the second bracket 150A4 in the mode of the opening blocking body frame 150A1.Motor box is formed by body frame 150A1, the first bracket 150A3 and the second bracket 150A4.Bearing 150A3b, 150A4b of free rotation ground supporting driving shaft 150A2 is respectively equipped with in the first bracket 150A3 and the second bracket 150A4.Be provided with rotor (not shown) in the periphery of the length direction central portion of driving shaft 150A2, the rotary magnetic field produced by stator to give rotatory force to driving shaft 150A2 with the interaction of the rotor being located at driving shaft 150A2.

The through first bracket 150A3 of one end 150A2a (right part of Fig. 1) of driving shaft 150A2, protrudes from outside from motor box, becomes output shaft 150A2a.In addition, the through second bracket 150A4 of the other end 150A2b of driving shaft 150A2, protrudes from outside from motor box, becomes the second output shaft 150A2b.The rotary encoder (without icon) of the rotation of the other end 150A2b detecting driving shaft 150A2 is built-in with in the second bracket 150A4.

In addition, below the first bracket 150A3 and the second bracket 150A4, a pair consent 150A3t and 150A4t exporting servo motor 150A for fixing twin shaft is respectively equipped with.Existing servo motor only the installation seat surface of the bracket of load-side (output shaft gives prominence to side) (right flank of Fig. 1) be provided with extend in parallel with driving shaft fixedly use consent.In purposes beyond precision optical machinery test, consent by means of only the installation seat surface being located at load-side bracket is fixed, but particularly apply in the precision optical machinery testing apparatus (such as fatigue test device and vibration-testing apparatus) of the dynamic loading of the high frequency of more than number 10Hz (such as 20Hz), when the servo motor using specified output to export for height more than 10kW degree, only fix with the installation seat surface of bracket, servo motor cannot be completely fixed in the direction vertical with driving shaft, the vibration of the small amplitude of such as several μm ~ several 10 μm of degree can be there is, thus cause the error cannot ignored test result.

In addition, on device pedestal 5002, adjuster (adjuster) A is configured with in the multiple positions close to substrate 5202,5302,5402.Adjuster A has and is fixed on the female threaded portion A1 of device pedestal 5002 with bolt AB and screws in the outer screw section A2 of this female threaded portion A1.Outer screw section A2 is the cylindrical element being formed with ridge in barrel surface, and is formed at the screwed hole of female threaded portion A1 by making outer screw section A2 be incorporated into and rotates, and outer screw section A2 can be made to retreat relative to the substrate of correspondence.One end (side in the nearly orientation of the substrate for correspondence) of outer screw section A2 forms roughly dome shape, by making this protuberance abut with a side of corresponding substrate, can carry out the inching of substrate position.In addition, the hexagon ring of not shown die nut is formed in the other end (side for the position, a substrate distant place of correspondence) of outer screw section A2.In addition, once after fixing base 5202,5302,5402, be installed on outer screw section A2 by nut A3, get loose because the vibration etc. being passed to adjuster A from substrate through vibration-testing causes to avoid outer screw section A2.Nut A3 is that the mode being connected to female threaded portion A1 with one end is installed, screw in nut A3 from this state and be pressed into female threaded portion A1, make axle masterpiece for outer screw section A2 and female threaded portion A1, by the frictional force that this axle power produces at the ridge of outer screw section A2 and female threaded portion A1, female threaded portion A1 is avoided to get loose from outer screw section A2.

Then, the formation of the first actuator 5200 is described.Figure 34 is the end view of the first actuator 5200 from Y direction (Figure 33 from right side to the left) viewing embodiments of the present invention.This resolution chart is short of a part to show internal structure.In addition, Figure 35 is the part shortcoming of the vertical view of the first actuator 5200 and shows internal structure.In addition, in the following description, be defined as along from the first actuator 5200 towards the direction of the X-axis of platform 5100 " X-axis positive direction ", be defined as along from platform 5100 towards the direction of the X-axis of the first actuator " X-axis negative direction ".

As shown in figure 34, on substrate 5202 by being welded with the framework 5222 be made up of the multiple beam 5222a be welded to one another and top board 5222b.In addition, carry out adding the driving mechanism 5210 that shakes in order to honour platform 5100 (Figure 33) and add for what make to utilize driving mechanism 5210 to carry out the base plate 5242 of Movement transmit to the supporting device 5240 of the connect mechanism 5230 of platform 5100 that shake, be fixed on the top board 5222b of framework 5222 via not shown bolt.

Driving mechanism 5210 has servo motor unit 150X, coupler 5260, bearing portion 5216, ball screw 5218 and ball nut 5219.Coupler 5260 links driving shaft 152X and the ball screw 5218 of servo motor unit 150X.In addition, the bearing support plate 5244 that bearing portion 5216 is fixed by base plate 5242 vertical welding to supporting device 5240 supports, and rotatably support ball screw 5218.Ball nut 5219 is not moved around axle and is supported by bearing support plate 5244, and is combined with ball screw 5218.Thus, when driving servo motor unit 150X, ball screw rotates, and ball nut 5219 is retreated at its direction of principal axis (that is X-direction).Be passed to platform 5100 by the motion of this ball nut 5219 via connect mechanism 5230, and drive platform 5100 in X-direction.Then, control servo motor unit 150X by the rotation direction switching servo motor unit 150X with the short period, with the amplitude of hope and cycle platform 5100 can be added and shake in X-direction.

On the base plate 5242 of supporting device 5240, rotor bearing cock 5246 vertically welds with base plate 5242.In the one side (face of X-axis negative direction side) of rotor bearing cock 5246, in the mode that driving shaft 152X is vertical with rotor bearing cock 5246, cantilever support servo motor unit 150X.Rotor bearing cock 5246 is provided with peristome 5246a, and driving shaft 152X this peristome through 5246a of servo motor unit 150X, links in the another side side of rotor bearing cock 5246 and ball screw 5218.

In addition because servo motor unit 150X be cantilever support in rotor bearing cock 5246, so can to rotor bearing cock 5246 particularly with the weld part of base plate 5242 on apply large bending stress.In order to relax this bending stress, and be provided with rib 5248 between base plate 5242 and rotor bearing cock 5246.

Pair of horns contact ball bearing (AngularBall Bearing) 5216a, 5216b that bearing portion 5216 has positive combination and combines (be 5216a X-axis negative direction side person, in X-axis positive direction, side person is 5216b).Angular contact ball bearing 5216a, 5216b are accommodated in inside the hollow bulb of bearing support plate 5244.Bearing pressing plate 5216c is provided with in the one side (face of X-axis positive direction side) of angular contact ball bearing 5216b, by using bolt 5216d that this bearing pressing plate 5216c is fixed on bearing support plate 5244, and angular contact ball bearing 5216b is pressed into X-axis negative direction.In addition, in ball screw 5218, threaded portion 5218a is formed with in barrel surface bearing portion 5216 being adjacent to X-axis negative direction side.The axle collar 5217 that inner circumferential is formed with negative thread can be installed in the 5218a of this threaded portion.Be displaced into X-axis positive direction by making the axle collar 5217 rotate relative to ball screw 5218, angular contact ball bearing 5216a is press-in X-axis positive direction.So, because angular contact ball bearing 5216a and 5216b is the approximating direction of press-in, therefore both are closely sealed each other and give bearing 5216a, 5216b by suitable prestrain.

Then, the formation of linking part 5230 is described.Linking part 5230 has nut guide card (NutGuide, spigot nut) 5232, a pair Y-axis track 5234, a pair Z axis track 5235, middle microscope carrier 5231, a pair X-axis track 5237, a pair X-axis rotor block 5233 and rotor block installation component 5238.

Nut guide card 5232 is fixed on ball nut 5219.In addition, a pair Y-axis track 5234 is together to the track that Y direction is stretched out, and is fixed on above-below direction side by side in the end of the X-axis positive direction side of nut guide card 5232.In addition, a pair Z axis track 5235 is together to the track that Z-direction is stretched out, and is fixed on Y direction side by side in the end of the X-axis negative direction side of platform 5100.Middle microscope carrier 5231 is the faces each the Y-axis rotor block 5231a combined with this Y-axis track 5234 being located at X-axis negative direction side, each Z axis rotor block 5231b combined with Z axis track 5235 is located at the square in the face of X-axis positive direction side, and both Y-axis track 5234 and Z axis track 5235 are formed slidably.

That is, middle microscope carrier 5231 can slide in Z-direction relative to platform 5100, and can slide in Y direction relative to nut guide card 5232.Therefore, middle microscope carrier 5231 can slide in Y direction and Z-direction relative to platform 5100.Thus, shaken in Y direction and/or Z-direction even if platform 5100 adds by other actuators 5300 and/or 5400, therefore nut guide card 5232 still unlikely and displacement conjugates.That is, the bending stress produced in the displacement displacement of Y direction and/or Z-direction because of platform 5100 is unlikely puts on ball screw 5218 or bearing portion 5216, coupler 5260 etc.

A pair X-axis track 5237 is together to the track that X-direction is stretched out, and is fixed on Y direction side by side on the base plate 5242 of supporting device 5240.Each of X-axis rotor block 5233 and this X-axis track 5237 combines, and can slide along X-axis track 5237.Rotor block installation component 5238 is the components being fixed on nut guide card 5232 bottom surface in the mode of stretching out towards Y direction both sides, and X-axis rotor block 5233 is fixed on the bottom of rotor block installation component 5238.So, nut guide card 5232 is directed at X-axis track 5237 via rotor block installation component 5238 and X-axis rotor block 5233, thereby, it is possible to only move in X-direction.

So, because the moving direction of nut guide card 5232 is only limited in X-direction, so when driving servo motor unit 150X and make ball screw 5218 rotate, nut guide card 5232 and the platform 5100 be combined with this nut guide card 5232 are retreated in X-direction.

Position detection component 5250 is configured with at a side side (be proximal lateral in Figure 34, be right side in Figure 35) 5238a of the Y direction side of rotor block installation component 5238.Position detection component 5250 has at certain intervals (arrangement) side by side in the retaining plate of sensor 5253 of 3 proximity transducers 5251 of X-direction, the detection plate 5252 being located at the side 5238a of rotor block installation component 5238 and supporting proximity transducer 5251.Proximity transducer 5251 can detect whether to have object close to the assembly of (such as within 1 millimeter) before each proximity transducer.Because the side 5238a of rotor block installation component 5238 and proximity transducer 5251 fully leave, so proximity transducer 5251 can detect whether had detection plate 5252 before each proximity transducer 5251.The control unit C5 of vibration-testing apparatus 5000 such as uses the testing result of proximity transducer 5251 can FEEDBACK CONTROL servo motor unit 150X (Figure 38).

In addition, on the base plate 5242 of supporting device 5240, be provided with and clip from X-direction both sides and configure the confinement block 5236 of X-axis rotor block 5233.This confinement block 5236 is for limiting the moving range of nut guide card 5232.That is, when driving servo motor unit 150X and make nut guide card 5232 continue mobile to X-axis positive direction, the confinement block 5236 being finally configured at X-axis positive direction side contacts with rotor block installation component 5238, and nut guide card 5232 cannot in the excessively movement of X-axis positive direction.Also same when making nut guide card 5232 continue mobile towards X-axis negative direction, the confinement block 5236 being configured at X-axis negative direction side contacts with rotor block installation component 5238, and nut guide card 5232 cannot in the excessively movement of X-axis negative direction.

First actuator 5200 described above and the second actuator 5300 are except the direction arranged different (X-axis and Y-axis are exchanged), and its structure is identical.Therefore, detailed description is omitted about the second actuator 5300.

Then, the formation of the 3rd actuator 5400 of embodiment of the present invention is described.Figure 36 is the end view from X-direction (from the below of Figure 16 upward) viewing platform 5100 and the 3rd actuator 5400.This end view is short of a part to show internal structure.In addition, Figure 37 is from Y direction (from the left side of Figure 33 to the right) the viewing platform 5100 of embodiment of the present invention and the end view of the 3rd actuator 5400.Figure 37 is short of a part to show internal structure.In addition, in the following description, be defined as Y-axis positive direction by along from the second actuator 5300 towards the direction of the Y-axis of platform 5100, be defined as Y-axis negative direction by along from platform 5100 towards the direction of the Y-axis of the second actuator 5300.

As shown in Figure 36 and Figure 37, substrate 5402 is provided with stretched out by vertical direction multiple beam 5422a, with cover the plurality of beam 5422a from top and framework 5422 that the top board 5422b that configures is formed.The lower end of each beam 5422a is welded in above substrate 5402, and upper end is welded in below top board 5422b.In addition, the bearing support plate 5442 of supporting device 5440 is fixed on the top board 5422b of framework 5422 by not shown bolt.This bearing support plate 5442 is, for supporting, platform 5100 (Figure 33) is added the driving mechanism 5410 that shakes and for driving mechanism 5410 added the component of Movement transmit to the connect mechanism 5430 of platform that shake at above-below direction.

Driving mechanism 5410 has servo motor unit 150Z, coupler 5460, bearing portion 5416, ball screw 5418 and ball nut 5419.Coupler 5460 links driving shaft 152Z and the ball screw 5418 of servo motor unit 150Z.In addition, bearing portion 5416 is fixed on described bearing support plate 5442, rotatably support ball screw 5418.Ball nut 5419 is not moved and is supported by bearing support plate 5442 around its axle, and is combined with ball screw 5418.Thus, when driving servo motor unit 150Z, ball screw rotates, and ball nut 5419 is retreated at its direction of principal axis (i.e. Z-direction).Be passed to platform 5100 by the motion of this ball nut 5419 via connect mechanism 5430, drive platform 5100 in Z-direction.Then, control servo motor unit 150Z by the rotation direction switching servo motor unit 150Z with the short period, with desired amplitude and cycle platform 5100 can be added and shake in Z-direction (above-below direction).

Below the bearing support plate 5442 of supporting device 5440, be fixed with the rotor bearing cock 5446 that (XY plane) in the horizontal direction expands via 2 webs 5443.Below rotor bearing cock 5446, hang servo motor unit 150Z and be fixed.In rotor bearing cock 5446, be provided with peristome 446a, driving shaft 152Z this peristome through 446a of servo motor unit 150Z, links in the top side of rotor bearing cock 5446 and ball screw 5418.

In addition, in the present embodiment, because the size of the direction of principal axis of servo motor unit 150Z (above-below direction, Z-direction) is larger than the height of framework 5422, so the major part of servo motor unit 150Z is configured at the position lower than substrate 5402.Thus, in device pedestal 5002, be provided with the blank part 5002a for receiving servo motor unit 150Z.In addition, be provided with in substrate 5402 servo motor unit 150Z by opening 5402a.

The through bearing support plate 5442 of bearing portion 5416 and arranging.In addition, because the structure of bearing portion 5416 is same with the bearing portion 5216 (Figure 34, Figure 35) in the first actuator 5200, therefore detailed description is omitted.

Then, the formation of linking part 5430 is described.Linking part 5430 has movable frame 5432, a pair X-axis track 5434, a pair Y-axis track 5435, multiple middle microscope carriers 5431, two pairs of Z axis tracks 5437 and two pairs of Z axis rotor blocks 5433.

Movable frame 5432 has the frame portion 5432a being fixed on ball nut 5419, the top board 5432b being fixed on the upper end of frame portion 5432a and X-direction two edge from top board 5432b and stretches out downwards and fixing sidewall 5432c.A pair Y-axis track 5435 is together to the track that Y direction is stretched out, and (arrangement) arranged side by side is fixed in X-direction on the top board 5432b of movable frame 5432.In addition, a pair X-axis track 5434 is together to the track that X-direction is stretched out, and (arrangement) arranged side by side is fixed in Y direction below platform 5100.Middle microscope carrier 5431 is for the X-axis rotor block be combined with X-axis track 5434 5431a is located at top, and each the Y-axis rotor block 5431b combined with Y-axis track 5435 is located at the square of bottom, and forms and can slide relative to both X-axis track 5434 and Y-axis track 5435.In addition, middle microscope carrier 5431 is that each position of intersecting at X-axis track 5434 and Y-axis track 5435 respectively establishes one.Because X-axis track 5434 and Y-axis track 5435 respectively establish two respectively, therefore X-axis track 5434 intersects at 4 places with Y-axis track 5435.Therefore, 4 middle microscope carriers 5431 are used in present embodiment.

So, each middle microscope carrier 5431 can slide in X-direction relative to platform 5100, and can slide in Y direction relative to movable frame 5432.That is, movable frame 5432 can slide in X-direction and Y direction relative to platform 5100.Thus, shaken even if platform 5100 adds in X-direction and/or Y direction by other actuators 5200 and/or 5300, therefore movable frame 5432 still unlikely and displacement conjugates.That is, the bending stress produced in the displacement displacement of X-direction and/or Y direction because of platform 5100 is unlikely puts on ball screw 5418 or bearing portion 5416, coupler 5460 etc.

In addition, in present embodiment, because the platform 5100 that taking the weight of is larger on movable frame 5432 and workpiece, thus X-axis track 5434 and Y-axis track 5435 interval of getting than the Y-axis track 5234 of the first actuator 5200 and Z axis track 5235 wide.Thus, in the same manner as the first actuator 5200, be set to when linking the formation of platform 5100 with movable frame 5432 by means of only microscope carrier in the middle of, middle microscope carrier will maximize, and cause the load increase putting on movable frame 5432.Thus, in present embodiment, be set to the formation that each several part intersected at each X-axis track 5434 and Y-axis track 5435 configures small-sized middle microscope carrier 5431, so that the magnitude of load putting on movable frame 5432 is suppressed at necessary bottom line.

Two pairs of Z axis tracks 5437 are the tracks stretched out to Z-direction, and fix for each a pair in Y direction at each sidewall 5432c (arrangement) arranged side by side of movable frame 5432.Each of Z axis rotor block 5433 and this Z axis track 5437 combines, and can slide along Z axis track 5437.Z axis rotor block 5433 is fixed on via rotor block installation component 5438 above the top board 5422b of framework 5422.Rotor block installation component 5438 has and the side plate 5438a of the almost parallel configuration of sidewall 5432c of the movable frame 5432 and base plate 5438b of lower end being fixed on this side plate 5438a, and entirety becomes L-shaped section shape.In addition, in the present embodiment, particularly that center of gravity is high and weight is large workpiece is fixed on platform 5100 time, the larger torque around X-axis and/or around Y-axis easily puts on movable frame 5432.Thus rotor block installation component 5438 utilizes rib (enhancing muscle) reinforcement to bear this rotating torque.Specifically, be that the corner that side plate 5438a at the Y direction two ends of rotor block installation component 5438 and base plate 5438b are formed arranges a pair first rib 5438c, be provided with further across the second rib 5438d between these a pair first rib 5438c.

So, Z axis rotor block 5433 is fixed on framework 5422, and can slide relative to Z axis track 5437.Therefore, movable frame 5432 can slide at above-below direction, and the movement of restraint framework 5432 beyond above-below direction.So, because the moving direction of movable frame 5432 is only limited in above-below direction, so when driving servo motor unit 150Z and make ball screw 5418 rotate, movable frame 5432 and the platform 5100 be combined with this movable frame 5432 are retreated at above-below direction.

In addition, same with the position detection component 5250 (Figure 34, Figure 35) of the first actuator 5200 position detection component (not shown) is also located at the 3rd actuator 5400.The control unit C5 of vibration-testing apparatus 5000 according to the testing result of this position detection component, can control the height of movable frame 5432 within the limits prescribed (Figure 38).

As described above, in the present embodiment, between the orthogonal each actuator of driving shaft and platform 5100, be provided with two pairs of tracks and can slide relative to this track and the middle microscope carrier that forms.Thus, platform 5100 can slide by any direction on the face vertical with the driving direction of its actuator relative to each actuator.Thus, even if cause platform 5100 displacement to conjugate because of certain actuator, the load produced because of this displacement and moment is unlikely puts on other actuators, and the state maintaining that other actuators and platform 5100 combine via middle microscope carrier.That is, even if platform is subjected to displacement displacement at an arbitrary position, the state that each actuator can make platform conjugate still is maintained.Thus, 3 actuators 5200,5300,5400 can be driven in present embodiment simultaneously, and platform 5100 and the workpiece be fixed thereon are carried out adding shaking at 3 direction of principal axis.

Again in present embodiment, as mentioned above, at actuator 5200, the linking part being provided with the guide possessing combined track and rotor block between 5300,5400 and platform 5100.In addition, same guide is located at actuator 5200,5300,5400, and this guide is the nut being used as the ball screw mechanism guiding each actuator.

In addition, in above-mentioned various execution mode, be use ultralow inertia servo motor in torque generating device, but formation of the present invention is not limited to this.The moment of inertia of the rotor formation of other forms of motor (such as inverter motor) that is little, that can drive with high acceleration or high acceleration is used also to be contained in the present invention.Now, in the same manner as above-mentioned various execution mode, can adopt and arrange encoder in the motor, the rotary state (such as revolution and angle position) of the motor output shaft detected according to encoder carries out the formation of FEEDBACK CONTROL.

In addition, above-mentioned execution mode is mainly suitable for example of the present invention in the durable test device of automobile power transmission, but the present invention is not limited to this, can be used in various uses in general industry.Such as the present invention can be used at two wheeler, agricultural machinery, construction implement, rolling stock, boats and ships, aircraft, electricity generation system, supply and drain water system or when forming the assessment of these the mechanical property of various parts and durability.

Be more than description of the present embodiment, but the present invention is not defined in above-mentioned formation, various distortion can be made in technical thought range of the present invention.Such as, in above-mentioned various execution mode, be the servo motor unit 150 (or torque imparting servo motor unit 132) that use two rank link that (having 1 output shaft) servo motor 150B and 1 twin shaft exports servo motor 150A, but more than a three rank link servo motor 150B and multiple twin shaft also can be used to export the formation of the servo motor unit of servo motor 150A.
