つく欠点がある。 Generally speaking, grinding of the outer diameter surface of this type of workpiece based on the axis is often done using center support on a cylindrical grinding machine, which has the drawback of requiring a large number of man-hours for loading, unloading, chucking, etc., resulting in high processing costs. be.

全く無視されることになり、偏心その他の不都合
が多発する。 There are also cases where the above-mentioned grinding is performed using a centerless grinding machine, but a centerless grinding machine supports the grinding outer diameter surface on the blade and the rotating circumferential surface of the adjustment wheel and grinds the outer diameter surface. For example, when grinding a workpiece W such as a rotor with a shaft for a small motor having a reference axis A as shown in FIG. , the coaxiality between the grinding outer diameter surface and the reference axis is completely ignored, resulting in frequent occurrence of eccentricity and other inconveniences.

いう不都合があり、さらに調整車の振れ、表面精
度が研削精度に大きく影響するという欠点があ
る。 For example, as shown in FIGS. 2 and 3, a grinding wheel 1, an adjusting wheel 2, and a blade 3 in between
In the centerless grinding machine, the reference axis A of the workpiece W is supported by the circumference of the blade 3 and the adjustment wheel 2, and the reference axis A is pressed against the blade 3 and the adjustment wheel 2 by the roller 5 attached to the arm 4. Grinding the grinding outer diameter surface B while regulating the position of the axis A (Fig. 2), or pressing the drive roller 6 against the grinding outer diameter surface B and forcibly rotating the workpiece W by the roller 6 instead of the adjustment wheel. While grinding (3rd
However, in the case of Fig. 2, the workpiece W is forcibly rotated by the adjusting wheel 2 which is in rolling contact with the reference shaft A, which has a small diameter, so the grinding outer diameter, which has a large diameter, has been proposed. Grinding resistance on surface B greatly exceeds the frictional force between reference shaft A and adjustment wheel 2, and accidents often occur in which slip occurs between reference shaft A and adjustment wheel 2, making grinding impossible. That is, there is the disadvantage that the slippage causes a high number of defective products, and furthermore, there is a disadvantage that the vibration of the adjusting wheel and the surface accuracy greatly affect the grinding accuracy.

軸径に対する研削外径面の寸法コントロールが難
しいという欠点もある。 On the other hand, in the case of Fig. 3, accidents due to slipping as described above are reduced, but since the small diameter reference shaft A is in rolling contact with the large diameter adjustment wheel 2, the runout of the adjustment wheel, surface accuracy, etc. are affected by the grinding. The drive roller 6 that presses down the workpiece W cannot avoid affecting the accuracy.
There is a limit to the diameter of the roller, which poses a problem in the lifespan of the roller. Furthermore, both the conventional examples shown in FIGS. 2 and 3 have the disadvantage that it is difficult to control the dimensions of the grinding outer diameter surface with respect to the reference shaft diameter.

In addition to significantly reducing the man-hours required for unloading, etc., and reducing the cost, the grinding accuracy such as coaxial accuracy and surface accuracy has been improved, and the configuration of the grinding device has been significantly simplified, making it possible to replace the centerless grinding device used in the past. The purpose is to easily adapt it to a grinding machine.

The adjustment wheel 2 is supported by an adjustment chassis 9 on a support base 8, and is rotationally driven in the direction of the arrow by a drive device (not shown). Note that when the adjustment wheel 2 is energized to perform depth of cut grinding, the support stand 8 is sent to the grinding wheel 1 side by a notching device (not shown), and conversely, when the grinding wheel 1 is energized to perform depth of cut grinding. In this case, the grinding wheel 1 is sent to the adjusting wheel 2, but since these structures are well known, their explanation will be omitted.

負荷が軽減される利益がある。 In the above, the lower shoe 11 is installed upright on the work rest 10 fixed on the support stand 8, and the horizontal support surface 12 that supports the reference axis A of the workpiece W is formed on the top surface. , the reference axis A of the workpiece W is to be placed on the support surface 12, and the reference axis A is
An upper shoe 13 facing upward is provided, and a supporting surface/processing reference surface 14 is formed on the lower surface of the upper shoe 13, which is a slope with the grinding wheel side lowered, and is urged toward the grinding wheel 1 side by the adjustment wheel 2. The peripheral surface of the reference axis A of the workpiece W is configured to contact the processing reference surface 14 on the side of the grinding wheel 1 from the perpendicular line V passing through the axis O thereof. As mentioned above, the upper shoe 13 works together with the lower shoe 11 to regulate the position of the reference axis A of the workpiece W relative to the grinding wheel 1, so its support is as follows:
Although not shown, the workpiece W may be held so as to be movable only in the vertical direction by a support member integrated with the workrest 10 or the support stand 8, or the workpiece W may be evacuated to a position where it does not get in the way during loading and unloading of the workpiece W. When the work rest 10 is placed on the support surface 12 and then set in a predetermined position, or when it does not interfere with loading and unloading, the work rest 10 is used together with the lower shoe 11.
Alternatively, it may be fixed at a predetermined position on the support stand 8. In the figure, the position of the rotation center O1 of the adjustment wheel 2 is shown to be higher than the horizontal line H passing through the axis O of the workpiece W by an amount h, but in Fig. There is no need to make a height difference between the center of rotation O1 and the center of rotation. However, if the configuration is as shown in the figure, there is an advantage that the load on the upper shoe 13 is reduced during forced rotation of the workpiece W.

軸心Ｏよりもｈだけ高い位置に設定する。 Fig. 4 shows an example in which the shoe is separated into upper and lower parts;
An L-shaped support surface 16 is provided at the upper end, and the surface extending in the vertical direction can be used as the machining reference surface 17. In this case, the rotation center O 1 of the adjustment wheel 2 can be set closer to the axis O of the workpiece W. Set it to a higher position by h.

In any case, the combination of the support surface and the machining reference surface is such that the machining reference surface contacts the peripheral surface of the reference shaft on the grinding wheel side of the perpendicular line passing through the axis of the reference shaft. A combination of planes or an arc shape with a wide open adjustment wheel side is used.

る。 This invention has the above-mentioned configuration, and after placing the reference shaft of the workpiece on the support surface of the shoe, the adjustment wheel 2 is urged toward the grinding wheel 1, and the circumferential surface is aligned with the workpiece. The grinding outer diameter surface B of W is brought into rolling contact, and the reference axis A is pressed against the machining reference surface 14 or 17, 17' for grinding.

要がなくなる。 In any case, the adjustment wheel only needs to press the reference axis of the workpiece against the machining reference surface, maintain that state (biasing force) constant, and forcibly rotate the workpiece. There is no role as such. Therefore, the adjusting wheel itself is made of an elastic friction body, or at least the peripheral surface that contacts the workpiece is made of an elastic friction body, or a biasing means for driving and biasing the adjusting wheel toward the grinding wheel is used. If an elasticity imparting means such as a spring is provided, the biasing force applied to the workpiece can always be maintained in a substantially constant state, and there is no need to provide a special biasing force adjusting means for driving the adjustment wheel.

ようにしたから、以下に列挙するような種々の効
果が得られる。 As described in detail above, according to the first invention, the position of the axis of the reference axis of the workpiece is regulated by the support surface and the machining reference surface provided on the shoe to make the cut, and the adjustment wheel is used to control the position of the axis of the workpiece. Since the grinding wheel is biased toward the grinding wheel and the outer diameter surface of the workpiece is thereby ground, various effects as listed below can be obtained.
(1) 調整車は、工作物の研削外径面等の最大直径
の部分に転接してその強制回転を行わせるか
ら、工作物の強制回転力がといし車と研削外径
面との間の研削抵抗力に負けてスリツプすると
いうような不都合がなく、工作物の安定した回
転が得られる。(1) Since the adjustment wheel rolls into contact with the maximum diameter part of the grinding outer diameter surface of the workpiece and forces its rotation, the forced rotational force of the workpiece is transferred between the grinding wheel and the grinding outer diameter surface. The workpiece can be rotated stably without the inconvenience of slipping due to the grinding resistance of the workpiece.
したがつて、従来のような上記スリツプによ

られる。 Therefore, there is no occurrence of defective products due to the slip as in the prior art, and stable grinding accuracy can be obtained.
(2) また、上記調整車は主として工作物の付勢手

工基準面により基準軸を支持して、その位置規
制を行うようにしている。(2) In addition, the above adjustment wheel mainly acts only as a means for urging the workpiece, and its circumferential surface does not act as a machining reference surface.On the other hand, the reference shaft is supported by the support surface of the shoe and the machining reference surface. and its location is regulated.

触れや表面精度等に全く影響されず、上記シユ
ーの加工基準面とといし車との関係によつて定
まり、よつて同軸精度、表面精度、寸法精度の
すべてに亘つて高精度の研削が可能となる。 Therefore, the grinding accuracy of the workpiece is completely unaffected by the touch of the adjusting wheel, surface accuracy, etc., and is determined by the relationship between the grinding reference surface of the shoe and the grinding wheel, and is therefore determined by the coaxial accuracy and surface accuracy. , high-precision grinding is possible over all dimensional accuracy.

が飛躍的に向上する。 In particular, the relationship between the shoe, which serves as a reference for machining the workpiece, and the reference axis is always maintained constant because the diameter of the reference axis is constant. The size control is much easier than before, and its accuracy is dramatically improved.

It can be easily adapted to conventionally used centerless grinding machines.
