Then, when rotary part 61 descended, the unit one W that loads on the workpiece loading plate 62 of measuring position R was loaded on the loading part 52 in it descends the way, and rotary part 61 and workpiece load plate 62 and drop to the decline end position.Thereafter, the workpiece W on the loading part 52 utilizes clamp mechanism (figure does not show) to clamp the inner peripheral surface of its through hole Wb, and simultaneously, compacting part 53 descends and joins with top, thus, and by this compacting part 53 and loading part 52 clampings.
And, by the external diameter of air compressing cylinder 58 to the gage outfit 56 measuring workpieces W of second axial workpiece W one side shifting, confirm whether in the size range of regulation, thereafter, this gage outfit 56 moves to the second axial direction of leaving workpiece W, and compacting part 53 rises, simultaneously, remove the clamping of chuck mechanism (figure does not show) to the inner peripheral surface of the through hole Wb of workpiece W.
On the other hand, by the decline of rotary part 61, the workpiece that is positioned at Working position Q loads second the workpiece W that loads on the plate 62, is loaded in the way of its decline on the loading part 31a of main shaft 31, and simultaneously, chuck 34 is inserted in the through hole Wb.And, same as described above and after fixing, can carry out grinding, at this moment, the direction of rotation of this second workpiece W, the situation during with above-mentioned unit one W is compared its reversed in order.Wherein, load the 3rd workpiece W of loading on the plate 62 at the workpiece that is positioned at supply/discharger P.
Thereafter, if rotary part 61 rises, then in the way that rises thereon, the loading part 31a of main shaft 31 and each the workpiece W on the loading part 52 are loaded into workpiece and load on the plate 62, and rise to the rising end position, by horizontally rotating of this rotary part 61, make the workpiece that is positioned at measuring position R load plate 62 and move to supply/discharger P, the workpiece that is positioned at Working position Q loads plate 62 and moves to measuring position R, and the workpiece that is positioned at supply/discharger P loads plate 62 and moves to Working position Q.
And if rotary part 61 descends, then each workpiece W of the second and the 3rd is loaded into the loading part 31a of loading part 52 and main shaft 31 respectively, implements the dimension measurement and the grinding of external diameter.Wherein, in the grinding of the 3rd workpiece W, the order of its direction of rotation is opposite with the above-mentioned second workpiece W, and is promptly identical with above-mentioned unit one W.On the other hand, the first workpiece W loads plate 62 from workpiece and discharges, and loads the 4th workpiece W.
After, repeat above-mentioned action and carry out grinding, utilize this grinding attachment 1 successively workpiece W to be carried out grinding, until n.
As mentioned above, according to grinding attachment 1 of the present invention, workpiece W whenever rotate a circle (direction of rotation that at every turn changes workpiece W), cup-shaped emery wheel T moves on axially second, change the outer peripheral face contact position of ablation face Ta and workpiece W, so the problem that can not grow in the generation cycle, and, even do not carry out complicated control, only just can change the contact position of ablation face Ta and workpiece outer peripheral face by shirtsleeve operation.And, by such change contact position, can prevent that only the part of the ablation face Ta of cup-shaped emery wheel T is worn, this ablation face Ta is worn substantially equably, can prolong the life-span of emery wheel.
And, because for each workpiece W, its direction of rotation all is to change according to just contrary order, so can prevent because the deviation that the wear extent of the ablation face Ta of the caused cup-shaped emery wheel T such as deviation of the grinding expense of this workpiece W produces, the wearing and tearing that the ablation face Ta of cup-shaped emery wheel T is subjected to are more even.
More than, an embodiment of the invention are illustrated, but the present invention the concrete form that can adopt, be not limited to above-mentioned embodiment.
In last example, when corase grind is cut, the ablation face Ta of cup-shaped emery wheel T and the contact position of workpiece outer peripheral face, be to change according to the order of the inner edge side part Pd of outer edge side part Pc, the ablation face Ta of part Pb, the ablation face Ta in the centre line L outside of part Pa, the ablation face Ta of the centre line L inboard of ablation face Ta, but also be not limited to such order, can be according to order variation arbitrarily.
And, the contact position of ablation face Ta and workpiece outer peripheral face is to change between four parts, but also be not limited to this, for example, also can between three parts of the inner edge side part of the outer edge side part of the central portion of the width of ablation face Ta, ablation face Ta, ablation face Ta, change.
And, be that the every rotation of workpiece W once (changes the direction of rotation of workpiece W) at every turn, change the outer peripheral face contact position of ablation face Ta and workpiece W, but also can be the every rotation of workpiece W repeatedly (whenever the direction of rotation of workpiece W changes repeatedly), change the outer peripheral face contact position of ablation face Ta and workpiece W, and, for the forward of the direction of rotation of workpiece W, reverse order, can not workpiece W of every processing, but a plurality of workpiece W of every processing and changing.
And, can also be workpiece W of every grinding, a plurality of workpiece W of perhaps every grinding, the outer peripheral face contact position of change ablation face Ta and workpiece W.
And it is the workpiece that is provided with jut Wa at outer peripheral face that workpiece W also is not limited to, and also can be columnar completely workpiece.
