Description

[Detailed Description of the Invention] This invention relates to a grindstone correction device used for reshaping and reshaping the grindstone of a cylindrical grinder.

In a whetstone correction device with a dresser attached to the Shinshindai, the holder of the dresser is fixed to the Shinjindai.
To correct the whetstone, it was necessary to move the holder along with the Shinshindai toward the whetstone, or conversely move the whetstone toward the Shinjindai.

This idea eliminates the need to move the grinding wheel head as well as the Shinshin stand, and by rotating the holder of a predetermined length and finely feeding the grinding wheel, the dresser at the tip of the holder can be reliably and easily handled. The purpose of this invention is to provide a grindstone correction device with a new structure that can perform the grinding process well.

This invention will be explained in detail below using illustrated examples.

Reference numeral 1 is a Shinshindai, and a Shinshin axis 2 is provided on the side end face so that it can move forward and backward.

A holder 5 of a dresser 4 is attached concentrically around a center 3 for fixing a workpiece protruding from the tip of the Shinshin stand 2 so as to rotate around the center 3.

Reference numeral 6 denotes a support portion of the holder 5, which is formed by stacking a pair of annular plates 6a and 6b each having a stepped portion on the circumferential side, and has a groove 6C formed by the stepped portion on the circumferential side.

The holder 5 is made of a plate with a required length, has a hole in its base that fits into the support part, and a groove 6C on the circumferential side of the hole.
It integrally has a protrusion 5a fitted into it.

In addition, the upper surface of the base of the holder 5 has a screw 7 attached to it.
A screw 8 for fixing the holder 5 is screwed into the support part 6 fixed to the dresser 4 attached to the tip.
It is possible to fix it with the screw 8 while it is in contact with the grindstone 9.

Note that 10 is a positioning pin, 11 is a pin guide groove, 12 is a cover, and 13 is a dustproof cover.

In the structure described above, since the holder 5 is rotatably attached around the center 3, it can be moved 180' around the center 3.

Therefore, when the workpiece is being polished by the grindstone 9, it can be maintained at the position shown by the chain line, and when corrections are being made, it can be rotated 180 degrees and fixed at a straight position.

Then, as long as the grindstone 9 is moved and brought into contact with the dresser 4, correction work such as reshaping or reshaping can be performed immediately.

As mentioned above, this invention includes a holder 5 of a required length concentrically with the sensor 3 on the heart axis 2 so as to be rotatable and fastened thereon,
Since the dresser 4 is attached to the tip of the holder 5, the rotation of the holder 5 is accompanied by a slight movement of the grindstone 9, thereby making it possible to reliably bring the dresser into contact with the grindstone.

Therefore, there is no need to move the Shinshin stand when correcting the grindstone, which greatly simplifies the work and improves efficiency.

In addition, since the holder is on the opposite side during grinding, it does not interfere with grinding, and the structure is simple as there is no need to process the Shinshindai, just by installing the holder around the center.
It has features such as being able to be used with conventionally structured cylindrical grinders.
