Then, illustrate the composition of the first actuator 5200.Figure 34 be from Y direction (Figure 33 from right side to the left) viewing this The side view of first actuator 5200 of the embodiment of invention.The test chart is short of a part to show internal structure. In addition, the part that Figure 35 is the vertical view of the first actuator 5200 is short of and shows internal structure.In addition, the following description In, it will be defined as " X-axis positive direction " along from the direction of the first actuator 5200 towards X-axis of platform 5100, it will be along from flat The direction of platform 5100 towards the X-axis of the first actuator is defined as " X-axis negative direction ".

As shown in figure 34, by being welded with multiple beam 5222a and top plate by being welded to one another on substrate 5202 The frame 5222 that 5222b is constituted.In addition, to prop up 5210 and of driving mechanism for honouring platform 5100 (Figure 33) and carrying out plus shaking Supporting device for the link mechanism 5230 for adding movement of shaking to be transferred to platform 5100 for making to carry out using driving mechanism 5210 5240 bottom plate 5242, is fixed in via not shown bolt on the top plate 5222b of frame 5222.

Driving mechanism 5210 has servo motor unit 150X, coupler 5260, bearing portion 5216,5218 and of ball screw Ball nut 5219.Coupler 5260 links the drive shaft 152X and ball screw 5218 of servo motor unit 150X.In addition, axis Bearing portion 5216 by supporting device 5240 bottom plate 5242 vertical welding by fixed bearing support plate 5244 supports, and can Rotationally rotating bearing ball screw rod 5218.Ball nut 5219 is not mobile around axis and supported by bearing support plate 5244, and with rolling Pearl screw rod 5218 combines.Thus, when driving servo motor unit 150X, ball screw rotation, ball nut 5219 is in its axis side It retreats to (that is, X-direction).It is transferred to platform 5100 via link mechanism 5230 by the movement of the ball nut 5219, and Platform 5100 is driven in X-direction.Then, it is watched by switching the rotation direction of servo motor unit 150X with short cycle to control Motor unit 150X is taken, by platform 5100 plus can be shaken in X-direction with desired amplitude and period.

In the upper surface of the bottom plate 5242 of supporting device 5240, rotor bearing cock 5246 is vertically welded with bottom plate 5242. The one side (face of X-axis negative direction side) of rotor bearing cock 5246, in such a way that drive shaft 152X is vertical with rotor bearing cock 5246, Cantilever support servo motor unit 150X.Opening portion 5246a is equipped on rotor bearing cock 5246, servo motor unit 150X's Drive shaft 152X penetrates through opening portion 5246a, links in another surface side of rotor bearing cock 5246 and ball screw 5218.

In addition, because servo motor unit 150X is cantilever support in rotor bearing cock 5246, motor can be supported Plate 5246 especially with apply big bending stress on the weld part of bottom plate 5242.In order to mitigate the bending stress, and the bottom of at Rib 5248 is equipped between plate 5242 and rotor bearing cock 5246.

A pair of of angular contact ball bearing (Angular Ball Bearing) that bearing portion 5216 is combined with positive combination 5216a, 5216b (being 5216a in X-axis negative direction side person, be 5216b in X-axis positive direction side person).Angular contact ball bearing 5216a, 5216b is accommodated in inside the hollow portion of bearing support plate 5244.Angular contact ball bearing 5216b one side (X-axis positive direction side Face) it is equipped with bearing pressing plate 5216c, bearing pressing plate 5216c is fixed on by bearing support plate by using bolt 5216d 5244, and angular contact ball bearing 5216b is pressed into X-axis negative direction.In addition, in ball screw 5218, to bearing portion 5216 The barrel surface for being adjacent to X-axis negative direction side is formed with threaded portion 5218a.Inner circumferential can be installed in the 5218a of the threaded portion to be formed with The collar 5217 of negative thread.It is displaced into X-axis positive direction by so that collar 5217 is rotated relative to ball screw 5218, angular contact Ball bearing 5216a is indentation X-axis positive direction.In this way, since angular contact ball bearing 5216a and 5216b are that indentation is closer to each other Direction, therefore the two is closely sealed each other and will suitably preload and assign bearing 5216a, 5216b.

Then, illustrate the composition of linking part 5230.Linking part 5230 has nut guide card (Nut Guide, spigot nut) 5232, a pair of of Y-axis track 5234, a pair of of Z axis track 5235, intermediate microscope carrier 5231, a pair of of X-axis track 5237, a pair of of 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 of of Y-axis track 5234 is to be stretched together to Y direction The track gone out, and upper and lower directions is fixed in the end of the X-axis positive direction side in nut guide card 5232 side by side.In addition, a pair of of Z axis rail Road 5235 is the track stretched out together to Z-direction, and Y-axis is fixed in the end of the X-axis negative direction side in platform 5100 side by side Direction.Intermediate microscope carrier 5231 is that the Y-axis rotor block 5231a of each combination with the Y-axis track 5234 is set to X-axis negative direction side Face, the Z axis rotor block 5231b of each combination with Z axis track 5235 is set to the square in the face of X-axis positive direction side, and to Y Both axis track 5234 and Z axis track 5235 are slideably constituted.

That is, intermediate microscope carrier 5231 can be slided relative to platform 5100 in Z-direction, and relative to 5232 energy of nut guide card It is enough to be slided in Y direction.Therefore, intermediate microscope carrier 5231 can be slided relative to platform 5100 in Y direction and Z-direction.Cause And it shakes in Y direction and/or Z-direction, nut even if platform 5100 is added by other actuators 5300 and/or 5400 Guide card 5232 still will not therefore displacement displacement.That is, being generated because platform 5100 is conjugated in the displacement of Y direction and/or Z-direction Bending stress will not be applied to ball screw 5218 or bearing portion 5216, coupler 5260 etc..

A pair of of X-axis track 5237 is the track stretched out together to X-direction, and on the bottom plate of supporting device 5,240 5242 It is fixed on Y direction side by side.Each combination of X-axis rotor block 5233 and the X-axis track 5237, can be along X-axis track 5237 And it slides.Rotor block installation component 5238 is to be fixed on 5232 bottom of nut guide card in a manner of being stretched out towards Y direction both sides The component in face, and X-axis rotor block 5233 is fixed on the bottom of rotor block installation component 5238.In this way, nut guide card 5232 via Rotor block installation component 5238 and X-axis rotor block 5233 and be directed at X-axis track 5237, thereby, it is possible to only X-direction move It is dynamic.

In this way, because the moving direction of nut guide card 5232 is only limited in X-direction, servo motor unit is driven 150X and when ball screw 5218 being made to rotate, nut guide card 5232 and the platform 5100 that is combined with the nut guide card 5232 are in X-axis It retreats in direction.

(it is proximal lateral in Figure 34, is right in Figure 35 in a side side of the Y direction side of rotor block installation component 5238 Side) 5238a be configured with position detection component 5250.Position detection component 5250 has at certain intervals (arrangement) side by side in X-axis 3 proximity sensors 5251 in direction, set on rotor block installation component 5238 side 5238a detection plate 5252 and branch Hold the retaining plate of sensor 5253 of proximity sensor 5251.Proximity sensor 5251 is can detect before each proximity sensor Whether object component close to (such as 1 millimeter within) is had.Because the side 5238a of rotor block installation component 5238 with connect Nearly sensor 5251 is sufficient away from so whether proximity sensor 5251 can detect has inspection before each proximity sensor 5251 It surveys and uses plate 5252.The control unit C5 of vibration-testing apparatus 5000 can for example be fed back using the testing result of proximity sensor 5251 Control servo motor unit 150X (Figure 38).

In addition, on the bottom plate 5242 of supporting device 5240, X-axis rotor block is configured equipped with being clipped from X-direction both sides 5233 confinement block 5236.The confinement block 5236 is used to limit the moving range of nut guide card 5232.That is, driving servo motor list First 150X and when nut guide card 5232 being made to be continued to move to X-axis positive direction, be finally configured at the confinement block 5236 of X-axis positive direction side It is contacted with rotor block installation component 5238, nut guide card 5232 can not excessively be moved in X-axis positive direction.Make 5232 court of nut guide card Also same when being continued to move to X-axis negative direction, the confinement block 5236 and rotor block installation component 5238 for being configured at X-axis negative direction side connect It touches, nut guide card 5232 can not excessively be moved in X-axis negative direction.

In addition to the direction of setting is different, (X-axis is mutual with Y-axis from the second actuator 5300 for first actuator 5200 described above Change) except, construction is identical.It omits and is described in detail accordingly, with respect to the second actuator 5300.

Then, illustrate the composition of the third actuator 5400 of embodiment of the present invention.Figure 36 is from X-direction (from Figure 16 Lower section upward) viewing platform 5100 and third actuator 5400 side view.The side view in order to show internal structure and A shortcoming part.In addition, Figure 37 is the platform for watching embodiment of the present invention from Y direction (to the right from left side of Figure 33) 5100 and third actuator 5400 side view.Figure 37 is short of a part to show internal structure.In addition, in theory below That will be defined as Y-axis positive direction along from the direction of the second actuator 5300 towards Y-axis of platform 5100 in bright, will along from The direction of platform 5100 towards the Y-axis of the second actuator 5300 is defined as Y-axis negative direction.

As shown in Figure 36 and Figure 37, the multiple beam 5422a stretched out by vertical direction are equipped on substrate 5402 and from top Cover multiple beam 5422a and the frame 5422 that constitutes of the top plate 5422b that configures.The lower end of each beam 5422a is welded in substrate The upper surface of 5402, upper end is welded in below top plate 5422b.In addition, the bearing support plate 5442 of supporting device 5440 passes through nothing The bolt of diagram and be fixed on the top plate 5422b of frame 5422.The bearing support plate 5442 is for supporting platform 5100 (Figure 33) in above-below direction plus the driving mechanism 5410 shaken and for by driving mechanism 5410 plus movement of shaking be transferred to it is flat The component of the link mechanism 5430 of platform.

Driving mechanism 5410 has servo motor unit 150Z, coupler 5460, bearing portion 5416,5418 and of ball screw Ball nut 5419.Coupler 5460 links the drive shaft 152Z and ball screw 5418 of servo motor unit 150Z.In addition, axis Bearing portion 5416 is fixed on the bearing support plate 5442, rotatably supports ball screw 5418.Ball nut 5419 does not exist It moves around its axis and is supported by bearing support plate 5442, and combined with ball screw 5418.Thus, drive servo motor list When first 150Z, ball screw rotation, ball nut 5419 is retreated in its axis direction (i.e. Z-direction).Pass through the ball nut 5419 movement is transferred to platform 5100 via link mechanism 5430, and platform 5100 is driven in Z-direction.Then, by with The rotation direction of short cycle switching servo motor unit 150Z controls servo motor unit 150Z, can be with desirable amplitude It by platform 5100 plus shakes in Z-direction (upper and lower directions) with the period.

Below the bearing support plate 5442 of supporting device 5440, it is fixed with towards level via 2 link plates 5443 The widened rotor bearing cock in direction (X/Y plane) 5446.Below rotor bearing cock 5446 hang servo motor unit 150Z and It is fixed.Opening portion 446a is equipped in rotor bearing cock 5446, the drive shaft 152Z perforations of servo motor unit 150Z should Opening portion 446a links in the upper surface of rotor bearing cock 5446 side and ball screw 5418.

In addition, in the present embodiment, because the axis direction (upper and lower directions, Z-direction) of servo motor unit 150Z The height of size ratio frame 5422 is big, so the major part of servo motor unit 150Z is configured at the position lower than substrate 5402. Thus, the blank part 5002a for storing servo motor unit 150Z is equipped in device pedestal 5002.In addition, in substrate In 5402 be equipped with servo motor unit 150Z by opening 5402a.

Bearing portion 5416 penetrates through bearing support plate 5442 and is arranged.In addition, since the construction of bearing portion 5416 and first cause Bearing portion 5216 (Figure 34, Figure 35) in dynamic device 5200 equally, therefore omits detailed description.

Then, illustrate the composition of linking part 5430.Linking part 5430 have movable frame 5432, a pair of of X-axis track 5434, A pair of of Y-axis track 5435,5431, two pairs of Z axis tracks 5437 of multiple intermediate microscope carriers and two pairs of Z axis rotor blocks 5433.

Movable frame 5432 has the frame portion 5432a for being fixed on ball nut 5419, the upper end for being fixed on frame portion 5432a Top plate 5432b and two edge of X-direction from top plate 5432b stretch out and fixed side wall 5432c downwards.A pair of of Y-axis track 5435 be the track stretched out together to Y direction, and in the upper surface of top plate 5432b of movable frame 5432 (arrangement) arranged side by side in X Axis direction and fix.In addition, a pair of of X-axis track 5434 is the track stretched out together to X-direction, and below platform 5100 It (arranges) and is fixed in Y direction side by side.Intermediate microscope carrier 5431 is the X-axis rotor block 5431a will to be combined with X-axis track 5434 Set on top, and by the Y-axis rotor block 5431b of each combination with Y-axis track 5435 set on the square of lower part, and it is configured to Relative to the sliding of both X-axis track 5434 and Y-axis track 5435.In addition, intermediate microscope carrier 5431 is in X-axis track 5434 and Y-axis The each position that track 5435 intersects respectively sets one.Since X-axis track 5434 and Y-axis track 5435 respectively set two respectively, X-axis Track 5434 intersects with Y-axis track 5435 at 4.Therefore, 4 intermediate microscope carriers 5431 are used in present embodiment.

In this way, each intermediate microscope carrier 5431 can be slided relative to platform 5100 in X-direction, and relative to movable frame 5432 can slide in Y direction.That is, movable frame 5432 can be slided relative to platform 5100 in X-direction and Y direction.Cause And even if platform 5100 is added in X-direction and/or Y direction by other actuators 5200 and/or 5300 and shaken, activity Frame 5432 still will not therefore displacement displacement.That is, because platform 5100 is produced in the displacement displacement of X-direction and/or Y direction Raw bending stress will not be applied to ball screw 5418 or bearing portion 5416, coupler 5460 etc..

In addition, in present embodiment, because of the taking the weight of bigger platform 5100 and workpiece on movable frame 5432, So Y-axis track 5234 and Z axis track of the interval that is taken of X-axis track 5434 and Y-axis track 5435 than the first actuator 5200 5235 is wide.Thus, in the same manner as the first actuator 5200, it is set as only linking platform 5100 and activity box by an intermediate microscope carrier When the composition of frame 5432, intermediate microscope carrier will be enlarged, and the load for being applied to movable frame 5432 is caused to increase.Thus, this implementation In mode, it is set to configure small-sized intermediate microscope carrier 5431 in each X-axis track 5434 and each section that Y-axis track 5435 intersects Composition, will be applied to movable frame 5432 magnitude of load inhibit in necessary bottom line.

Two pairs of Z axis tracks 5437 are the tracks stretched out to Z-direction, and each side wall 5432c of movable frame 5432 simultaneously Arrange (arrangement) in Y direction and each pair is fixed.Each combination of Z axis rotor block 5433 and the Z axis track 5437, and can be along Z axis track 5437 and slide.Z axis rotor block 5433 is fixed on the top plate of frame 5422 via rotor block installation component 5438 The upper surface of 5422b.Rotor block installation component 5438 has the side plate with the substantially parallel configurations of side wall 5432c of movable frame 5432 5438a and be fixed on side plate 5438a lower end bottom plate 5438b, it is whole to become L-shaped section shape.In addition, in this reality It applies in mode, when being especially fixed on the workpiece that center of gravity is high and weight is big on platform 5100, around X-axis and/or around Y-axis Larger torque is easy to be applied on movable frame 5432.Thus rotor block installation component 5438 is to utilize rib (enhancing muscle) reinforcement To bear the rotating torque.Specifically, being the side plate 5438a at the Y direction both ends of rotor block installation component 5438 and bottom A pair of of first rib 5438c of corner setting that plate 5438b is constituted, is further provided between a pair of first rib 5438c The second rib 5438d.

In this way, Z axis rotor block 5433 is fixed on frame 5422, and can be slided relative to Z axis track 5437.Therefore, movable Frame 5432 can slide in above-below direction, and the movement other than limiting movable frame 5432 in above-below direction.In this way, because living The moving direction of dynamic frame 5432 only limits in above-below direction, so driving servo motor unit 150Z and making ball screw 5418 When rotation, movable frame 5432 and the platform 5100 combined with the movable frame 5432 are retreated in above-below direction.

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

As described above, in the present embodiment, between the orthogonal each actuator of drive shaft and platform 5100 Equipped with two pairs of tracks and the intermediate microscope carrier that can be constituted relative to track sliding.Platform 5100 is relative to each actuating as a result, Device can be slided in any direction on the face vertical with the driving direction of its actuator.Thus, even if caused by some actuator 5100 displacement of platform conjugates, and the load and torque generated by the displacement will not be applied to other actuators, and maintain other actuatings The state that device and platform 5100 are combined via intermediate microscope carrier.That is, even if platform is subjected to displacement displacement at an arbitrary position, still tie up Hold the state that each actuator can be such that platform conjugates.Thus, can be driven simultaneously in present embodiment 3 actuators 5200,5300, 5400, and platform 5100 and the workpiece being fixed thereon are carried out plus shaken in 3 axis directions.

Again in present embodiment, have as described above, being equipped between actuator 5200,5300,5400 and platform 5100 The linking part of the guiding mechanism of combined track and rotor block.In addition, same guiding mechanism be set to actuator 5200,5300, 5400, which is used as guiding the nut of the ball screw mechanism of each actuator.
