Description

[Detailed explanation of the invention] This invention is designed to prevent edge spalling by dressing the surface of the whetstone into a taper and cutting the barrel edge of the roll into a predetermined shape. The present invention relates to a grindstone dressing device intended to provide a tool support device.

Conventionally, various structures have been proposed and put into practical use for devices that correct and polish the surface used on a grindstone (hereinafter referred to as the abrasive surface) to a flat surface. As there is no proposal for a device yet, and it depends entirely on the skill of the operator, the accuracy of the finish of the abrasive surface depends on the quality of the skill.

However, with this invention, the tool arm is automatically operated by a lever linked to the grinding wheel head, and the direction of the taper of the grinding surface and the size of the taper can be adjusted, so there is no need to rely on skilled technique. They succeeded in automatically finishing an accurate abrasive surface.

That is, to explain this invention with reference to an embodiment, a guide groove 2 is provided on the whetstone head 1 at right angles to the direction of movement thereof, and a pin 4 protruding from one end of an arm 3 is slidably inserted into the guide groove 2. , the other end of the arm 3 is rotatably attached to one end of a U-shaped lever 6 via a hinge 5, and one end of a connecting rod 7 is rotatably attached to the other end of the lever 6. It is rotatably attached to the upper end of the tool arm 8, a diamond tool 9 is fixed to the lower part of the tool arm 8, and the mounting pins 10 and 11 are removably inserted into the upper and lower parts of the mounting part of the diamond tool 9. The arm 8 is attached to the guide tool 13 of the tailstock 12.

Several mounting holes 14 are provided at the other end of the lever 6, and the arm is rotatably mounted to the tailstock using bolts 15. By changing the mounting position of the bolts 15, the taper angle of the grinding surface can be adjusted. can be changed.

In the embodiment described above, in order to dress the tapered abrasive surface, the arm is first folded down, the pin 4 is inserted into the guide groove 2, and the hinge 5 is tightened to integrate the arm and the lever.

Next, when the grindstone head 1 is moved in the direction of arrow 16 in FIG.
7, and the connecting rod 7 also moves in the same direction to move the tool arm 8 in the direction indicated by the arrow 18 with the pin 10 as the center.
The grinding surface of the whetstone 24 is finished by moving in the direction of .

In the embodiment described above, if the position of the port 15 is moved in the direction of arrow 20, the ratio of tool movement relative to the movement of the grinding wheel head will be increased, so the taper angle will be increased, and if the position of port 15 is moved in the direction of arrow 21, the taper angle will be reduced. Become.

When the grindstone head 1 is moved in the direction of arrow 19 in FIG. 5, the arm 3 rotates in the direction of arrow 22 around the bolt 15 in the figure, and the connecting rod 7 also moves in the same direction. In this case, the tool arm 8 rotates in the direction of arrow 23 about the pin 11 (to remove the pin 10), and the abrasive surface can be finished.

In other words, even if the moving direction of the grindstone head is reversed, the tool moves in the same direction and at the same rate, so that the grinding surface can be finished with a symmetrical taper.

Next, rotate the arm from the hinge as shown by arrow 25 in Figure 2, remove it from the groove of the grindstone head 1, and set the pin 1011 on the
\, the abrasive surface can be finished flat, so
It can also be used to finish conventional flat grindstones.

In other words, according to this invention, the arm and lever are connected so that the tool is moved perpendicular to the grinding surface in conjunction with the movement of the grindstone head, so it is possible to accurately and automatically grind the tapered grinding surface without requiring advanced technology. can be finished.

Further, by attaching and detaching the arm, it is possible to finish a tapered abrasive surface or a flat abrasive surface, and the taper angle can be adjusted by adjusting the mounting position of the lever.
