And, after the processing of above-mentioned workpiece W and exchange finish, turntable 40 Rotate 180 degree.Like this, make the second pallet 12b move to workpiece Working position, the unprocessed workpiece W being arranged on the second pallet 12b is processed.On the other hand, the first pallet 12a moves to workpiece switch from workpiece Working position, and the workpiece W that completes processing having on the first pallet 12a is taken off to (then, unprocessed workpiece W being newly arranged on the first pallet 12a) from the first pallet 12a.
As implied above, in automatic pallet switch 10, turntable 40 carries out (also referred to as " calibration ") in rotary moving of 180 degree rotations and static repeatedly.
About the structure of automatic pallet switch 10
, use Fig. 2 to Fig. 7 below, the structure of automatic pallet switch 10 is described.Fig. 2 is the stereogram of wanting portion that represents automatic pallet switch 10.Fig. 3 is the top view of automatic pallet switch 10.Fig. 4 is the side view of automatic pallet switch 10.Fig. 5 is the partial enlarged drawing of Fig. 4.Fig. 6 is the figure of the situation that represents that stationary cam follower 66 engages with the groove 62b of deviation post with situation that conventionally the groove 62b of position engages and stationary cam follower 66.In addition, Fig. 7 describes in the back.
Output rotating part 26 is fixed on output shaft 34, there is two cam-follower support portions 28 of two circular cam follower support portion 28(axially the fixing side by side along output shaft 34 with the 34 one rotations of this output shaft), wherein, this output shaft 34 is set to it axially and the axially parallel of described power shaft 32.In the present embodiment, due to output shaft 34 axially also along vertical, so arrange along the vertical direction (for convenient two cam-follower support portions 28, the cam-follower support portion 28 of upside is called to overhead cam follower support portion 28a, the cam-follower support portion 28 of downside is called to lower cam-follower support portion 28b).
And, in the present embodiment, as shown in Figure 3, multiple (8) cam-follower 29 is arranged on (cam-follower 29 equally spaced arranges along the circumferencial direction of circular cam-follower support portion 28) on cam-follower support portion 28, and these cam-followers 29 are specifically all sides of plane cam 22 with the holding section 24(of parallel cam 20) engaging.Thus, the revolving force of described drive source is via power shaft 32 and two plane cams 22 of parallel cam 20() be passed to cam-follower support portion 28 and be then passed to output shaft 34., output shaft 34(cam-follower support portion 28) be accompanied by the parallel cam 20 of power shaft 32() rotation and rotate.
If more specifically described, 4 cam-follower 29(in 8 cam-followers 29 are the 2nd, 4,6, No. 8 cam-followers 29 in Fig. 3) be arranged on overhead cam follower support portion 28a above, remain 4 cam-follower 29(is the 1st, 3,5, No. 7 cam-followers 29 in Fig. 3) be arranged on lower cam-follower support portion 28b.And, because upper plane cam 22a is corresponding with overhead cam follower support portion 28a, lower plane cam 22b is corresponding with lower cam-follower support portion 28b, so, if power shaft 32 rotates, the holding section 24(that goes up plane cam 22a is specifically for the projection of upper plane cam 22a is the holding section 24 of projection 22c) the cam-follower 29(the 1st of pushing overhead cam follower support portion 28a, 3, 5, the cam-follower 29 of No. 7), in addition, the holding section 24(body ground of lower plane cam 22b says for the projection of lower plane cam 22b be the holding section 24 of projection 22c) pushing descends the cam-follower 29(the 2nd of cam-follower support portion 28b, 4, 6, No. 8 cam-followers 29), thus, cam-follower support portion 28 and output shaft 34 are rotated.
Fig. 7 represents the parallel cam 20 of power shaft 32() the anglec of rotation and output shaft 34(cam-follower support portion 28) the anglec of rotation between the schematic diagram of relation.
As aforementioned projection 22c, be provided with as shown in Figure 34 projections, , be arranged on the first projection 22d on lower plane cam 22b, be arranged on the second projection 22e on plane cam 22a, be arranged on the 3rd projection 22f on lower plane cam 22b and be arranged on the 4th projection 22g on plane cam 22a, when parallel cam 20 rotates with the rotation of power shaft 32, with the first projection 22d, the second projection 22e, the 3rd projection 22f, the order of the 4th projection 22g, push respectively the 1st, 2, 3, No. 4 cam-follower 29(are in Fig. 7, the anglec of rotation of power shaft 32 is from till 0 degree to 270 degree).And, if the 4th projection 22g finishes (in Fig. 7 the pushing of No. 4 cam-follower 29, the anglec of rotation of power shaft 32 is 270 degree), the not part of projection 22c of plane cam 22 is that holding section 24 engages with cam-follower 29, although parallel cam 20 rotates, but cam-follower support portion 28 and output shaft 34 become non-rotary state (in Fig. 7, the anglec of rotation of power shaft 32 is from till 270 degree to 360 degree).
As implied above, the related parallel cam mechanism 18 of present embodiment has output rotating part 26(cam-follower support portion 28) though between the non-stacking area rotating with the rotation of parallel cam 20 and parallel cam 20 rotate but export rotating part 26(cam-follower support portion 28) between non-rotary stacking area.And, if the parallel cam 20 of power shaft 32() rotate a circle, as shown in aforementioned, the projection 22c of plane cam 22 only pushes when (5th～No. 8 cam-followers 29 are at the parallel cam 20 of power shaft 32() rotates for the second time and is urged 4 in 8 cam-followers 29 (1st～No. 4) cam-followers 29), therefore, output shaft 34 and cam-follower support portion 28 rotate 1/2 week (Rotate 180 degree) (in Fig. 7, the anglec of rotation of output shaft 34 is from till 0 degree to 180 degree).
In addition, because turntable 40 and described output rotating part 26 are fixed on output shaft 34 in the same manner, so rotate with output rotating part 26 one.Thus, by the action of above-mentioned (and shown in Fig. 7) output rotating part 26, realize the action of foregoing turntable 40, that is, repeatedly carried out (also referred to as " calibration ") in rotary moving and the static action of 180 degree rotations.
As shown in Figure 5, these shaft coupling parts 50 have: as the upper inner side shaft coupling 50a of the ring-type of an example of the first shaft coupling portion, it is arranged in the below part of turntable 40; The upper outside shaft coupling 50b of ring-type, it is arranged on housing, and is positioned at the outside of inner side shaft coupling 50a, than the large circle of upper inner side shaft coupling 50a; And as the downside shaft coupling 50c of the ring-type of an example of the second shaft coupling portion, it is positioned at the below of inner side shaft coupling 50a and upper outside shaft coupling 50b, also they is called to upside shaft coupling altogether with upper inner side shaft coupling 50a and upper outside shaft coupling 50b() relatively arrange.
Because upper inner side shaft coupling 50a is arranged on turntable 40, so rotate together with the rotation of turntable 40, on the other hand, upper outside shaft coupling 50b and downside shaft coupling 50c do not rotate.In addition, upper inner side shaft coupling 50a and upper outside shaft coupling 50b do not move along upper and lower (vertical) direction, and on the other hand, downside shaft coupling 50c can move along the vertical direction by downside shaft coupling driving mechanism 60 described later.
And 50c is moved upward towards upside shaft coupling by downside shaft coupling, thereby downside shaft coupling 50c and upside shaft coupling are in conjunction with (engagement), are rotated thus the location of platform 40.
In addition in the regulation time point (a part is interval) of the related shaft coupling parts 50 of present embodiment between stacking area, turntable 40 is positioned.
Specifically, as shown in Figure 7, by downside shaft coupling driving mechanism 60 described later, the interval (being called between positioning area) till the anglec of rotation of power shaft 32 is 300 degree to 330 degree, utilizes shaft coupling parts 50 to realize location.Specifically, making in the anglec of rotation is 300 while spending, and downside shaft coupling 50c starts to rise, and is 330 while spending in the anglec of rotation, the downside shaft coupling 50c end that declines.And, between this positioning area with the processing and implementation of workpiece W during corresponding, therefore, can be positioned under the state of tram at turntable 40 and workpiece W, carry out the processing of workpiece W.In addition, utilize the adhesion of shaft coupling parts 50, can improve rigidity, and under the state that suppresses vibration generation, carry out correspondence processing.
In addition, as shown in aforementioned, turntable 40 and the 26 one rotations of output rotating part.Therefore,, if turntable 40 is positioned, exports rotating part 26 and be also positioned., shaft coupling parts 50 position turntable 40 and output rotating part 26 by being arranged on the combination of upper inner side shaft coupling 50a on turntable 40 and downside shaft coupling 50c.
Downside shaft coupling driving mechanism 60 is for moving up and down downside shaft coupling 50c.This downside shaft coupling driving mechanism 60 has grooved cam 62, grooved cam driven wheel 68, pushing dish 70 and disk spring 72.
The parts that this grooved cam 62 is ring-type, its central shaft is coaxial with aforementioned output rotating part 26.But this grooved cam 62 can be with respect to output rotating part 26(and output shaft 34 and turntable 40) independent rotation.And the outer peripheral face 62a of this grooved cam 62 is upper along circumferentially forming groove 62b, this groove 62b and stationary cam follower 66(, are fixed on housing and irremovable cam-follower) engage.
Here, the formation position of the groove 62b on above-below direction (groove 62b is formed on which position on the above-below direction of grooved cam 62), is all positioned at constant position in nearly all part of the whole circumference of groove and (is called common position UP.With reference to the upside figure of Fig. 6), but (be called deviation post SP in part to skew below described constant position.With reference to the downside figure of Fig. 6).Therefore, rotation when if the groove 62b of grooved cam 62 engages with stationary cam follower 66, when stationary cam follower 66 arrives deviation post SP from common position UP (, when state from the state variation of the upside figure of Fig. 6 to downside figure), grooved cam 62 entirety upward (to shaft coupling parts 50 sides) are mobile (because stationary cam follower 66 cannot move, therefore, grooved cam 62 moves.Contrast is with reference to upside figure and the downside figure of Fig. 6).
In addition, stationary cam follower 66 arranges at least 3 (being in the present embodiment 3)., in the present embodiment, stationary cam follower 66 as shown in Figure 3, is provided with 3 along circumferentially equally spaced the interval of 120 degree (, with).In addition, in the same manner, described deviation post SP is also arranged on 3 positions along circumferentially equally spaced the interval of 120 degree (, with).Therefore,, in the time that stationary cam follower 66 arrives deviation post SP, 3 stationary cam followers 66 all arrive deviation post SP simultaneously.And under described situation, 3 stationary cam followers 66 become fulcrum and lifting (pushing) grooved cam 62.
In addition, on the position of grooved cam 62 below the groove 62b of outer peripheral face 62a, there is the gear teeth 62c forming along circumferentially.And these gear teeth 62c engages with the grooved cam driven wheel 68 being fixed on power shaft 32, when power shaft 32 being rotated by described drive source, utilize grooved cam driven wheel 68 and grooved cam 62 is rotated., move and make turntable 40(and output shaft 34 and output rotating part 26 by this drive source) and grooved cam 62 the two rotate together.
In addition, the gear ratio of grooved cam driven wheel 68 and grooved cam 62 is 1:3.Therefore, the parallel cam 20 of power shaft 32() rotation is during 1 week, and grooved cam 62 rotates 1/3 week.On the other hand, because stationary cam follower 66 and deviation post SP are as shown in aforementioned, be equally spaced provided with 3, therefore, whenever grooved cam 62 rotates 120 degree, stationary cam follower 66 just arrives deviation post SP.Therefore, the parallel cam 20 of power shaft 32() rotate during 1 week, must there is 1 stationary cam follower 66 to arrive deviation post SP and grooved cam 62 is moved upward, thereby make 50 combinations of shaft coupling parts.
In addition, as shown in aforementioned, grooved cam 62 moves and downside shaft coupling 50c is pushed towards upside shaft coupling (upper inner side shaft coupling 50a) to shaft coupling parts 50 sides (being in other words top), but not directly pushes downside shaft coupling 50c, but indirectly pushes via some parts.; the related grooved cam 62 of present embodiment is arranged between grooved cam 62 and shaft coupling parts 50 via pushing dish 70 described later with as these parts of disk spring 72(of an example of spring members); pushing downside shaft coupling 50c, moves downside shaft coupling 50c and makes downside shaft coupling 50c and the combination of upside shaft coupling.
Pushing dish 70 is arranged on the parts of the upside of grooved cam 62 and the downside of downside shaft coupling 50c.This pushing dish 70 loads on grooved cam 62, therefore, can move up and down with the moving up and down interlock of grooved cam 62.On the other hand, with respect to the rotatable situation of grooved cam 62, pushing dish 70 cannot rotate (describing in the back for the mechanism that realizes this situation (cannot rotate)).Therefore, pushing dish 70 rotates relatively with respect to grooved cam 62, thus, in order to make this relative smooth rotation, and between pushing dish 70 and grooved cam 62, ball bearing 74 is installed.
In addition, on pushing dish 70, locate in the position (in other words, the position of each stationary cam follower 66 tops) corresponding with aforementioned 3 stationary cam followers, 66 difference, be provided with the protuberance 70a protruding upward., protuberance 70a is arranged on 3 positions along circumferentially equally spaced the interval of 120 degree (, with).And the protuberance 70a at these 3 positions has disk spring 72 separately, this disk spring embeds in this protuberance 70a.
And downside shaft coupling 50c is arranged on pushing dish 70 with the state of clamping disk spring 72.Therefore, pushing dish 70 pushes downside shaft coupling 50c via disk spring 72.
In addition, downside shaft coupling 50c is arranged on pushing dish 70 (, downside shaft coupling 50c and pushing coil 70 chimeric) under the chimeric state that has protuberance 70a of hole portion being arranged on this downside shaft coupling 50c.In addition, be provided with cotter way 50d in the side of downside shaft coupling 50c, owing to being inserted with the pin 76 as brake in this cotter way 50d, so downside shaft coupling 50c becomes and cannot rotate.Thus, pushing dish 70 also with downside shaft coupling 50c in the same manner, become and cannot rotate.And, thus, can make to be arranged on disk spring 72 on the protuberance 70a of pushing dish 70 and be positioned at all the time the top of stationary cam follower 66, can utilize as 3 stationary cam followers 66 of fulcrum and stably push disk spring 72.
About the validity of the related cam gear of present embodiment (automatic pallet switch 10)
The related automatic pallet switch 10 of above-mentioned embodiment has: turntable 40; Shaft coupling parts 50, it carries out the location of described turntable 40 by being arranged on the combination of the first shaft coupling portion on this turntable 40 (upper inner side shaft coupling 50a) and the second shaft coupling portion (downside shaft coupling 50c); Stationary cam follower 66; And grooved cam 62, it has groove 62b, when engaging with described stationary cam follower 66 by this groove 62b, be rotated and move, this grooved cam 62 to described shaft coupling parts 50 side shiftings and by one in described the first shaft coupling portion and described the second shaft coupling portion towards another pushing, thus, a described shaft coupling portion moved and make a described shaft coupling portion and described another shaft coupling portion combination.
As shown in aforementioned, in order to make the first shaft coupling portion and the combination of the second shaft coupling portion, need to make one in both to move to another, but in the prior art, this action realize by use hydraulic mechanism etc.But, in this case, due to the existence of hydraulic mechanism, the problem that generation device maximizes.
On the other hand, in the present embodiment, owing to using above-mentioned stationary cam follower 66 and grooved cam 62, a described shaft coupling portion is moved to described another shaft coupling portion, thereby compared with existing example, can realize very compact new automatic pallet switch 10.
In addition, in the above-described embodiment, stationary cam follower 66 is at least provided with 3.Therefore, can realize following structure, that is, 3 above stationary cam followers 66 become fulcrum, promote (pushing) grooved cam 62 and a described shaft coupling portion (downside shaft coupling 50c) is moved to described another shaft coupling portion (upper inner side shaft coupling 50a).
In the prior art, do not have the mechanism that uses stationary cam follower 66 and grooved cam 62, if the known product of actual observation, corresponding fulcrum only has 2.And realize following structure, that is, utilize these 2 fulcrums to support on one side, on one side a described shaft coupling portion is moved to described another shaft coupling portion.But, because fulcrum only has two to cause producing this problem of deficient in stability.
On the other hand, in the present embodiment, by adopting the mechanism of above-mentioned use stationary cam follower 66 and grooved cam 62, can increase simply the quantity of stationary cam follower 66, thereby 3 above fulcrums are set., in the present embodiment, because stationary cam follower 66 is at least provided with 3, so can utilize 3 above fulcrums stably to support a described shaft coupling portion on one side, this shaft coupling portion is moved on one side to described another shaft coupling portion.
In addition, between grooved cam 62 and shaft coupling parts 50, be provided with disk spring 72, grooved cam 62 pushes a described shaft coupling portion (downside shaft coupling 50c) via disk spring 72.Therefore, produce following advantages.
If in the situation that not there is not disk spring 72, in order to export desired pushing force, just need to carry out accurate grooved cam 62 Position Control (this be due to, in the situation that not there is not disk spring 72, the position of the above-below direction of grooved cam 62 is slightly offset and will makes pushing force occur significantly to change).On the other hand, in the present embodiment, because grooved cam 62 pushes a described shaft coupling portion (downside shaft coupling 50c) via disk spring 72, so do not need accurate grooved cam 62 Position Control (this be due to, owing to there being disk spring 72, even if so the position on the above-below direction of grooved cam 62 is offset, pushing force also less changes).
In addition, also have drive source, it makes turntable 40 and grooved cam 62 the two rotates simultaneously by moving.Specifically, parallel cam 20 is arranged on together with grooved cam driven wheel 68 on the power shaft 32 being rotated by drive source, by parallel cam 20, turntable 40 is rotated respectively, by grooved cam driven wheel 68, grooved cam 62 is rotated.And, can realize like this minimizing of number of components.
