Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fixing jig for a diamond dresser used for forming a grindstone of a grinding machine.

Prior Art A diamond dresser used for forming a grinding wheel for a cylindrical grinder, a universal grinder, etc. is usually fixed to the upper surface of a rotating table 2 via a mounting jig 3, as shown in FIGS. 1 and 2. By moving the dresser 1 along with the left and right slide tables 4, the grindstone 5 is given a predetermined linear shape.

In such conventional equipment, the dresser 1
In order to set the angle α with respect to the grindstone 5, it is necessary to delicately adjust the turning table 2 and the mounting jig 3, and there is a problem that the adjustment is difficult and takes a lot of time. In addition, if the turning angle δ of the turning table 2 with respect to the left and right slide table 4 is set large, there is a risk that the base metal part 1' of the dresser 1 will interfere with the grinding wheel 5, so the turning angle δ should be kept small. Or, it is necessary to select a mounting jig 3 with an inclination angle in advance as shown in Fig. 1.
Another problem is that the operation is complicated and requires a lot of setup time. Furthermore, in order to avoid worn parts of the dresser 1 and produce sharp dressing points 6, it is necessary to turn the dresser 1 frequently, but this adjustment also requires a lot of time.

Purpose of the invention In order to solve the above-mentioned problems, the purpose of the invention is to make it possible to set the angle of the dresser with respect to the grindstone and move the worn part of the dresser quickly and easily. do.

Structure and function of the invention The dresser fixing jig of the invention that meets this purpose is
It consists of a dresser rotating tool that attaches the dresser and a fixed base that rotatably holds the dresser rotating tool. The dresser is configured to be mounted at an angle with respect to the dresser rotation tool so as to be located at the intersection with the center axis of the tool.

In such a dresser fixing jig, by rotating the dresser rotating tool, the central axis of the dresser moves while drawing a circular locus with the dressing point as the apex. Therefore,
By simply rotating the dresser together with the dresser rotation tool, the inclination angle of the dresser with respect to the grinding wheel can be set arbitrarily.The angle can be set quickly with simple operations, and at the same time, by rotating the dresser, the contact position of the dresser with the grinding wheel can be adjusted. Since the angle is set, the wear part of the dresser is also moved, and a sharp dressing point can be easily obtained.

Embodiments Hereinafter, preferred embodiments of the dresser fixing jig of the present invention will be described with reference to the drawings.

3 and 4 show a dresser fixing jig according to an embodiment of the present invention. In the figure, 10
1 shows a dresser, which consists of a diamond 11 fixed to the tip and a base metal part 12 that holds it. The dresser 10 is a rotating table 1
3 via a dresser fixing jig 14.

The dresser fixing jig 14 includes a dresser rotating tool 15 to which the dresser 10 is attached, and a fixed base 16 that rotatably holds the dresser rotating tool 15. The lower part of the dresser rotating tool 15 is rotatably fitted into a recessed portion of the fixed base 16, and is fixed to the fixed base 16 by a set screw 17.

The dresser rotating tool 15 has a dresser mounting portion 18.
The dresser 10 is inserted into the dresser mounting portion 18 and fixed with a set screw 19. The dresser mounting portion 18 is formed such that the dressing point 20 of the attached dresser 10 is located at the intersection of the center axis 21 of the dresser 10 and the center axis 22 of the dresser rotating tool 15, and the dresser 10 is The dresser rotating tool 15 is mounted at an angle. That is, the central axis 21 of the dresser 10 and the central axis 22 of the dresser rotating tool 15 are inclined by an angle β, and the central axis 21 of the dresser 10 and the lower surface of the grindstone 23 are inclined by an angle α in the state shown in FIG. It is being

In the dresser fixing jig configured as described above, the angle of the dresser 10 with respect to the grindstone 23 is set by rotating the dresser 10 together with the dresser rotating tool 15 around the center axis 22 of the dresser rotating tool 15.

That is, since the dressing point 20 of the dresser 10 is located at the intersection of the center axis 21 and the center axis 22, if the dresser 10 is rotated, the dresser 10 will turn into a circular shape with the dressing point 20 as the apex. Draw the trajectory of the shape. Therefore, the angle α between the dresser 10 and the grindstone 23 when viewed from the direction shown in FIG. 3, that is, the angle α when viewed from the X direction in FIG.
is set to any angle between α and α+2β by selecting the rotation angle of the dresser 10. This angle setting can be done by simply rotating the dresser rotating tool 15 to which the dresser 10 is attached, so there is no need for complicated adjustments as in the past.
Operation is simplified and setup time is significantly reduced. Further, the angle of the dresser mounting portion 18 is set to an appropriate angle, and the angle between the dresser 10 and the grindstone 23 will not become less than α by rotating the dresser 10. The fear that the metal part 12 will come into contact with the grindstone 23 is also eliminated.

In addition, by rotating the dresser 10, the grindstone 23 at the dressing point 20 can be rotated.
Since the contact position with the dresser 10 is also moved, the worn part of the dresser is moved at the same time as the angle of the dresser 10 is set. This eliminates the need for independent adjustment of the movement of the worn part of the dresser and makes it easier to create a sharp dresser. You will get sing points.

Effects of the invention As explained above, when using the dresser fixing jig of the present invention, the angle between the dresser and the grindstone is set by rotating the dresser together with the dresser rotating tool into a circular shape with the dressing point as the apex. This makes it possible to simplify the adjustment when changing the dresser angle, and has the effect of significantly shortening the required time to about 2/5 of the conventional method.

In addition, since the contact position of the dresser with the grindstone is also moved as the angle of the dresser changes, the individual adjustment work for moving the worn part of the dresser, which was previously performed, is no longer necessary, making the work even easier. This also has the effect of making it easier and saving time.
