Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a grindstone shaping device, and more particularly to a grindstone shaping device that grinds and shapes a rotating grindstone using a diamond roll for grindstone shaping.

[Prior Art 1] Conventionally, in order to shape a rotary whetstone 10, as shown in FIG. The grindstone 10 was ground and shaped by applying it to the grindstone 10 to be shaped and rotating the grindstone 10 in opposite directions while bringing the surface of the diamond roll 4 for grindstone shaping into pressure contact with the surface of the grindstone 10.

This conventional diamond roll 4 for grinding wheel shaping is made by bonding fine diamond particles, and its cross-sectional curve is formed in a shape that is the inverse of the cross-sectional curve of the target grinding wheel 10. diamond roll 4
The grindstone 10 that is ground by the rotation is shaped according to the curve of the cross section of the diamond roll 4 for shaping the grindstone.

[Problems to be Solved by the Invention] However, according to the prior art, the rotating shaft 10 of the grindstone 10
a and the rotating shaft 4a of the diamond roll 4 for grindstone shaping are arranged in a parallel direction, and the diamond roll 4 for grindstone shaping
Since the same part of the surface of the grinding wheel 10 grinds the same part of the surface of the grinding wheel 10, the shaping accuracy (shape accuracy and surface roughness) of the grinding wheel 10 is improved.
is determined by the accuracy of the diamond roll 4 for grinding wheel shaping.
There was a problem that high quality was required, and therefore the cost was high.

Furthermore, when the grindstone 10 is required to have a particularly high degree of shaping accuracy, the diamond roll 4 for shaping the grindstone must be replaced even if it is slightly worn, and therefore there is a problem that the effective life of the grindstone is shortened. .

Further, the conventional diamond roll 4 for shaping a grindstone is limited to a shaped shape or a unique shape, and there is a problem in that it cannot be shaped into a shape other than the unique shape.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides the following grindstone shaping device.

That is, the present invention provides a diamond roll for grinding wheel shaping, which is formed by solidifying fine diamond particles into a cylindrical shape and grinding and shaping the grindstone by rotation, a grinding wheel rotation axis for rotating the curved grindstone to be shaped, and a grindstone rotation axis perpendicular to the grindstone rotation axis. a diamond roll rotation axis arranged in the direction of the diamond roll for rotating the diamond roll for grinding wheel shaping, and a plurality of controls capable of simultaneously controlling mutual positions and spacings of the diamond roll for grinding wheel shaping and the grinding wheel by numerical control; It is a grindstone shaping device equipped with a shaft.

[Function] In the above configuration, since the two axes of the rotation axis of the grindstone shaping diamond roll and the rotation axis of the grindstone are perpendicular to each other, the grindstone shaping diamond roll grinds and shapes the surface of the grindstone in a random manner.

Adjustment of the position and spacing between the grindstone shaping diamond roll and the grindstone is performed by simultaneous movement of a plurality of numerically controlled control axes.

The adjustment by numerical control does not affect the accuracy of the shaped shape of the grindstone even if the diamond roll for shaping the grindstone is worn.

[Embodiments] With regard to embodiments of the present invention, how the structure of the present invention is actually embodied will be described below with reference to the drawings, together with its operation.

FIG. 1 is a front view of one embodiment of the present invention. In the figure, 1 is a base of a grindstone shaping device, and a table 2 is placed on this base 1. is also table 3
is placed on the table 3, and a diamond roll 4 for grindstone shaping having a diamond roll rotation shaft 4a and a diamond roll rotation drive motor 6 for rotationally driving the diamond roll 4 for grindstone shaping with a belt 5 are attached. .

The table stand 2 is composed of two parts, an upper sliding part 2a and a lower fixed part 2b, and by sliding the upper sliding part 2a on the lower fixed part 2b, the diamond roll for grinding wheel shaping is applied. 4 and the diamond roll drive motor 6 can be moved along with the table 3 in a direction perpendicular to the plane of the drawing.

Further, the base 1- is provided with a whetstone head 7, and this whetstone head 7 is driven by a motor 8 for moving the whetstone head back and forth for moving it along a back-and-forth direction control axis 8a by numerical control, and a downward control axis 9a. Grinding wheel head vertical movement motor 9 to move along
or installed.

These movements are simultaneously and smoothly carried out by numerical control of the control shafts 8a, 9a, etc.

Further, a whetstone 10 having a whetstone rotation shaft 10a is rotatably attached to the whetstone head 7, and a whetstone rotation driving motor 11 for rotationally driving the whetstone 10 is attached.

The diamond roll rotation shaft 4a and this grindstone rotation shaft 10a are provided in a direction perpendicular to each other.

While rotating, the grindstone 10 moves up and down and back and forth as shown by chain lines under the numerical control, and its peripheral surface is ground and shaped by the diamond roll 4 for grindstone shaping, which rotates in an orthogonal direction.

FIG. 2 is a plan view of the same embodiment, and in the figure, 12 is a motor for moving the table left and right;
Therefore, during grinding, the diamond roll 4 for grinding wheel shaping moves along with the table 3 in the direction of the left-right control shaft 12a and comes into pressure contact with the rotating grindstone 10, and can be separated when not grinding.

Also in this plan view, it can be seen that the diamond roll rotation axis 4a and the grindstone rotation axis 1.0a are provided in orthogonal directions.

FIG. 3 is an enlarged front view of the main parts of the same embodiment, and is a diagram showing the mutual operational relationship between the grindstone 10 and the diamond roll 4 for shaping the grindstone.

That is, since the rotational direction of the grindstone 10 and the rotation direction of the diamond roll 4 for grindstone shaping are perpendicular to each other, when considering the surface of the grindstone 10 as the center, the surface of the grindstone 10 is the same as that of the diamond roll 4 for grindstone shaping. Since the grinding wheel 10 is ground to a random pattern, the surface of the grindstone 10 is not affected by the surface roughness of the diamond roll 4 for shaping the grindstone, and can be made smooth.

In addition, in this figure, for convenience of explanation, the grindstone 1o side is moved only by rotation, and the grindstone shaping diamond roll 4 side is shown as moving around the grindstone 1o while rotating to explain the relative movement. Actually, in this embodiment, as shown in FIGS. 1 and 2, the grindstone 0 side moves around the diamond roll 4 for shaping the grindstone.

FIG. 4 is an explanatory side view of FIG. 3, which more clearly illustrates the movement of the surface of the grindstone 1° and the movement of the surface of the diamond roll 4 for shaping the grindstone.

As can be seen in this figure, the surface of the whetstone 1o is ground by an unspecified surface of the diamond roll 4 for whetstone shaping, so the surface roughness requires the diamond roll 4 for whetstone shaping to be highly precise. In addition, since the shape shaping is performed by numerical control, the diamond roll 4 for grinding wheel shaping can maintain the shaping precision even if it wears out. Therefore, the diamond roll 4 for grinding stone shaping has a special shape. Cost 1~ as it does not require precision or accuracy and is long lasting.
It is possible to make it cheaper.

As described above with respect to the embodiments, the present invention includes a rotating diamond roll for shaping a grinding wheel made of fine diamond particles compacted into a cylindrical shape, and its rotation axis is set at an angle perpendicular to the rotation axis of the grindstone to be shaped. The surface of the rotating whetstone is randomly ground and smoothed by the surface of the diamond roll for whetstone shaping that rotates in the orthogonal direction, so the surface roughness of the diamond roll for whetstone shaping requires strict precision. Therefore, costs can be reduced.

In addition, the shape of the whetstone to be shaped can be formed into a curved surface because multiple control axes that can be controlled simultaneously are numerically controlled, and even if the diamond roll for shaping the whetstone wears out, the shaping accuracy of the whetstone is controlled numerically. At the same time, the diamond roll for grinding wheel shaping can have a longer useful life.

Furthermore, since the shaped shape is formed by controlling a plurality of control axes through numerical control, it is possible to flexibly meet the needs of diversifying various shapes, such as a small number of many models.

[Effects of the Invention] According to the present invention, the rotating axis of the grinding wheel and the rotating axis of the diamond roll for grinding wheel shaping are configured to be perpendicular to each other, so that the surface of the grinding wheel is ground and shaped in a random manner. Since the specific surface of the diamond roll is eliminated from grinding the specific surface of the grinding wheel, the surface roughness can be greatly improved and product quality can be improved.

In addition, since it is equipped with multiple control axes that can be controlled simultaneously by numerical control, the shape accuracy is not affected by the accuracy of the diamond roll for shaping the whetstone, and an inexpensive diamond roll for shaping the whetstone can be used, thus reducing equipment costs. Can be lowered.

Furthermore, since it is equipped with multiple control axes that can be controlled simultaneously by numerical control, it can be ground and shaped into various shapes such as a perfect circle, ellipse, and parabola using the same diamond roll for shaping the grindstone, responding to diversifying shape needs.

In addition, even if the diamond rolls for grinding wheel shaping become worn out, the mutual position and spacing can be corrected through numerical control, ensuring shaping accuracy and extending the useful life of the diamond rolls for grinding wheel shaping. There are some effects like this.
