４の上端の角度は90°−β即ち90°＋α／２である。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. A base 3 having a guide surface 3a in the vertical direction is vertically fastened to a mounting base 2 fixed on a table 1 of a grinding machine, and an upper surface 4a is attached to the base 3 at an angle of 90° to the horizontal line toward the grinding wheel. A cradle 4 with a forward downward slope of angle 2, that is, an apex angle of 90°+α/2, is fastened. The receiving table 4 and the base 3 are fixed with the receiving surface 5a having an angle α° with the horizontal plane forming one of the V surfaces that receives the workpiece W so as to be slidable up and down along the guide surface 3a as the upper surface. A side plate 5 is interposed and fixed to the base 3 with bolts so as to be adjustable within the vertically elongated hole 5b. The sliding side plate 6 forming the other side of the V surface that receives the workpiece W has a receiving surface 6a that is straight in a guide groove 5c that is inclined and cut parallel to a plane that forms an angle α° with a horizontal plane that is one surface of the V surface. It is slidably fitted and is adjustable and fastened to the stationary side plate 5 with bolts within the range of the elongated hole 6b in the sliding direction. A scale is engraved on the side surface to determine the amount of protrusion of the sliding side plate corresponding to the diameter of the workpiece, so that the position can be adjusted to match the base line of the fixed side plate 5. In addition, the sliding side plate 6
The end surface 6d on the grindstone side is formed so as not to interfere with the grindstone and maintain the necessary rigidity to receive the workpiece W, but is normally formed so that it is tangent to the workpiece and the grindstone when attached. Further, as shown in FIG. 3, the receiving surface 6a of the sliding side plate 6 is protruded in correspondence with the diameter of the workpiece, so that the support axis is on the same line when receiving the workpiece. Since the fixed side plate 5 is moved up and down according to the diameter of the filter, the receiving surface 6a
has been moved in parallel. Therefore, the sliding side plate 6
Find the angle of the opposite end of the grindstone. In Fig. 5, the angle between the receiving surface 6a and the horizontal plane is α, and when the workpiece diameters are d 1 and d 2 , the front ends E and E of the receiving surface 6a of the sliding side plate are on the common tangent line between the workpiece and the grindstone. If the receiving surface 6a of the sliding side plate 6, that is, EF is
Translated to E′F′, EFF′E′ is a parallelogram and <
EFF′=<AE′B. ＜If AOE′=β＜
AE′B=α+β and <OLE′=<OME′=90°,
Since OE′ is common and OL=OM, △OLE′≡△
OME′, ∴LOE′=＜MOE′=β and △ONM and △
Since <AON=90° with ANO, <OMN
=90° or <ONA is common, so <OAN=<MON=α ∴<AOM+<MON=2<AOE′+<MON=2β
+α=90° ∴β=90°−α/2 ∴<EFF′=α+β=α+90°−α/2=90°+α/2 Therefore, the angle between the sliding side plate 6 and the lower end surface 6e<EFF'=90°+α/2, and the trapezoidal shape is formed such that the angle between the upper end surface 6d and the receiving surface 6a is 90°−α. The inclined surface of the pedestal 4 is a straight surface 4a so that the sliding side plate 6 is positioned thereon.
Since the side surfaces are vertical, the angle of the upper end of the pedestal 4 is 90°-β, that is, 90°+α/2.

Next, the fixed side plate 5 is lowered by loosening the bolts fixing it to the base 3, and the lower end surface 6e of the sliding side plate is brought into contact with the receiving surface 4a of the pedestal 4 and fixed with bolts, and the work holder holds the workpiece concentrically. Be prepared to accept the situation. Therefore, when a workpiece W of 60φ is supported at the center on the spindle side and the center on the tailstock side, the work holder receiving surfaces 5a and 6a contact the lower surface of the workpiece and support it without bending.

れは皆無となる特徴を有するものである。Effects As detailed above, the present invention forms a lower end angle at a predetermined angle of a sliding side plate that is provided on a fixed side plate through one side of a V-shaped receiving surface so as to be slidable in the direction of one side of another V-shaped receiving surface. Since a cradle is provided on the end surface of the base plate, the position of the plate and base is automatically determined by simply adjusting the scales of the sliding and fixed side plates, making adjustment work easier and reducing setup time. be able to. Furthermore, since the sliding side plate is fixed in contact with the pedestal, there is no risk that the sliding side plate will move and the work holder will not be able to function satisfactorily, even in the case of heavy workpieces. .
