The formation of the grasping device of present embodiment is described below with reference to Fig. 5.
Fig. 5 is the side view of the grasping device of present embodiment.As shown in Figure 5, the grasping device 10 of present embodiment possesses: make handle part that a pair of holding jig 2 and 3 and provide the hold of hold that unit 40 is provided to a pair of holding jig 2 and 3 of workpiece relatively is provided on machine table 50.Wherein, the both ends of the holding jig 2 on top are fixed on the machine table 50 with support 20.Hold provides unit 40 to come to provide hold to the holding jig 2 of upside and 3 of the holding jigs of downside by the holding jig 3 that promotes downside.
In the present embodiment, the holding jig 2 of upside is provided in the one-piece type holding jig 2 that is provided with bar seam row 13 and 14 in the handle part 15.Therefore, can control whole work-piece with the same basically power with the holding jig 2 of this simple integral structure.Its result, will holding jig along cutting apart on the Workpiece length direction, with regard to each holding jig of cutting apart hold being set respectively the unit is provided.Therefore, compare, can make and the small-sized light bodyization of grasping device can reduce the grasping device manufacturing cost with the occasion of cutting apart holding jig.
In addition, in the present embodiment, because that the grasping device of the holding jig that this grasping device 10 is cut apart with setting is compared is in light weight, so grasping device 10 is moved on high accuracy rectilinear orbit 70 with more speed.Its result helps shortening minute surface and cuts the fabrication cycles cycle that disappears.
At this holding jig with reference to Fig. 6 and 7 explanation present embodiments.Fig. 6 (A) is the side view of the holding jig of present embodiment, and Fig. 6 (B) is a ground plan of seeing holding jig shown in Fig. 6 (A) from the face of controlling one side.Be noted that and in Fig. 6 (B),, the face of controlling added hacures represented though be not the cross section part.Fig. 7 (A) is the end view drawing of holding jig shown in Figure 6, and Fig. 7 (B) is the side partial enlarged drawing of holding jig shown in Fig. 6 (B).
In the present embodiment, describe as the holding jig of workpiece control optical conduction array row (not shown) with handle part.The optical conduction array row are elongated rectangle, and the end face on its length direction is processed by mirror-finish cutting.Therefore, as Fig. 6 (A) and (B), the holding jig 2 of present embodiment is elongated one-piece type shape, is metal system.
Shown in Fig. 6 (B), the face of controlling 11 of controlling the handle part 15 of workpiece is with certain width straight line extension shape.The length L of controlling on the length direction of face 11 is preferably long than the length on the length direction of workpiece.In addition, width (being orthogonal to the thickness on the direction of the length direction) D that controls face 11 is advisable to be shorter than optical conduction array col width (perpendicular to the length on the direction of the end face of being processed by mirror-finish cutting).Here, the length L of establishing on the length direction of the face of controlling is hundreds of mm, the width D of controlling face 11 for number mm about.
Shown in Fig. 7 (A), along the handle part 15 of the face of controlling 11 of holding jig 2, its thickness is same as the width D of the face of controlling, and is thinner than support portion 16, so that do not run into bite during cutting.
Shown in Fig. 6 (A), in the present embodiment, have the 1st and the 2nd the seam row 13 and 14 that dotted line shape ground formation respectively is parallel to a plurality of seams 12 of the face of controlling 11 in handle part 15 sides.Each bar seam 12 that bar stitches row 13 and 14 runs through handle part 15.First and second stitches row 13 and 14, preferably is longer than Workpiece length, and in the present embodiment, the total length that is actually on the face of controlling 11 length directions is provided with.With regard to the gap-shaped shape, also can stitch two ends and make circular hole at bar, its bore dia stitches width greater than bar.
Like this, two row bars seam row 13 and 14 are set, can give flexible the handle part 15 of holding jig 2 by being parallel to the face of controlling 11.Its result when controlling workpiece, can produce strain because of bar seam 12 shrivels with the handle part 15 of the thicker position of workpiece correspondence.Therefore, controlling face 11 can be by the localized indentation thick projection that absorbs workpiece or recessed that contracts.
Also have, each bars seam 12 dislocation each other of 12 and the 2nd seams of each bar seam row 14 of the 1st seam row 13 forms staggeredly, makes bar stitch bar that 12 two ends 12a lists with other seams and stitches 12 overlapping.
By staggered landform slivering seam 12, just can apply the flexible of equalization in fact along its length to the face of controlling 11 of holding jig 2.Like this, even if with little thick projection or recessed workpiece, also can control with all basic the same power on the whole work-piece length direction it.
Handle part 15 is made as suitable with metal, if then better with all high spring steel (SUP) manufacturing of hard and tough high-speed steel (SKH) or elastic limit and fatigue limit.If adopt this metalloid, then, give flexible easily by bar seam row are set.
Illustrate each bar when making whole holding jig 2 with SKH or SUP below with reference to Fig. 7 (B) and stitch 12 etc. advantageous configurations and size shape, can apply in view of the above is enough to absorb the thick projection of workpiece or recessed flexible by the elastic limit internal strain.Fig. 7 (B) is the 1st and the 2nd partial enlarged drawing that stitches row 13 and 14 shown in Fig. 6 (A).
Control the interval H of face 11 and the 1st seam row 13
1The scope of thickness that is stratiform part 17 is to be advisable with interior 0.5-2 times of the face of controlling 11 wide D.For example, if D=3.5mm, then H
1=5mm.
In the present embodiment, the scope of bar seam length S is to be advisable at wide 3-5 times of the face of controlling 11.
S is big more for bar seam length, flexible big more along the stratiform part 17 of bar seam 12 and 18.But 12 long if bar stitches, may cause along the hold of the face of controlling 11 of bar seam not enough.
In the present embodiment, in all bar seam row 13,14, the length S of its seam 12 is the same, and interval T is too between the bar seam.S=20mm for example, T=10mm.
Also have, because that the two ends 12a of each bar seam 12 stitches with other bars that list is 12 overlapping, so the interval T between the bar seam is shorter than bar seam length S.
The scope of the width U of each seam 12 is advisable with 0.1-0.5mm.For example, U=0.2mm.
When the face of controlling of holding jig when absorbing thick projection or recessed and recessed contracting, the deformation extent of controlling face is the degree that the bar seam shrivels fully that reaches to the maximum.Therefore, bar seam width is excessive, then may cause the holding jig distortion to surpass elastic limit.When utilizing cylinder or helical spring to wait to produce hold, as long as this power can be controlled in the strain, bar seam width bigger also can.On the other hand, if bar seam width is too small, then be difficult to fully be out of shape thick projection or recessed.
Be enough to make it to lean on the elastic limit internal strain to absorb the thick projection of workpiece or recessed flexible by resembling the bar seam 12 that disposes above-mentioned size above-mentioned, just can applying to the handle part 15 of controlling parts 1.
Certainly, also can consider to absorb the thick projection of workpiece or recessed on the face of controlling 11 by rubber layer is set.But rubber layer also can be out of shape on the direction of the face of controlling 11, so if adopt rubber layer, workpiece can be offset because of cutting stress when cutting.Therefore, with regard to controlling the workpiece this point securely, it not is suitable that rubber layer is set.
By contrast, the holding jig 2 that tape seam 12 is set of present embodiment, the stratiform part 17 of its handle part 15 has distortion on the direction perpendicular to the face of controlling 11 with 18 actually as leaf spring, and is in fact producing distortion on the direction of the face of controlling 11.Therefore, by the holding jig 2 of present embodiment, can control workpiece with power impartial on the Workpiece length direction, and can firmly fix workpiece simultaneously.
