Description

[Detailed description of the idea] When attaching a cutting tool to the tool post of a lathe, the height of the cutting edge is aligned with the center of rotation of the main shaft of the lathe.

For this purpose, we prepare in advance various thicknesses of bottom plates to be interposed between the tool rest and the cutting tool, and each time we attach the cutting tool to the tool post, we select the appropriate thickness of the bottom plate through trial and error. To do this quickly requires a certain amount of experience and sensitivity.

Therefore, when some technicians remove a used cutting tool from the tool rest, they also remove the bottom plate used for the cutting tool, combine them, and store them on a sorting table in preparation for next use.

In this case, you have to be careful not to separate the bite and the bottom plate and prevent it from collapsing.

The bites stored on these sorting tables are usually placed on a plurality of bottom plates, so they are very unstable.

Therefore, when inserting and removing these bits, you have to be careful not to touch the adjacent bits with your fingertips and cause them to collapse.

From the above, it is necessary to store the cutting tools at intervals that allow enough space for the fingertips, which increases the area occupied by the sorting table.

The present invention provides a device for improving these problems.

The configuration of this embodiment will be described with reference to FIG.
The L-shaped fitting 1 has a lower plate 1- facing the bottom of the cutting tool 3.
2 and a standing plate 1-1 facing the side surface of the cutting tool 3, the L-shaped metal fitting has an L-shaped cross section, and is sized to match the cross-sectional dimensions of the cutting tool and its length. A flat magnet 2 is placed on the surface of the standing plate 1-1 at the internal angle of 1.
It is used as a bottom plate holding fitting by attaching it.

Next, to describe an example of its use, when the inner corner of the L-shaped fitting 1 is brought close to the bottom surface of the cutting tool 3 to be attached to the tool post, the magnet 2 attached to the vertical plate 1-1 will be attracted to the side surface of the cutting tool 3. do.

In this case, the side surface of the cutting tool 3 to which the magnet 2 is attracted should be on the inside when it is attached to the tool rest.

Next, place the cutting tool 3 and L-shaped fitting 1 in this state on the tool rest, and place the bottom plate 4 on the lower plate 1-1 according to the height of the cutting edge.
2 and cutting tool 3, and align the height of the cutting edge with the center of rotation of the main shaft of the lathe.

In this case, the cutting tool 3 and the L-shaped fitting 1 are attracted to each other on their sides by the magnet 2, but when the bottom plate 4 is inserted or removed, the direction of the attracting surface will shift, but as is well known, the magnet will absorb the shift in both directions. However, since the resistance force is relatively weak, it can easily adapt to vertical changes of the lower plate 1-2 of the cutting tool 3 and the L-shaped fitting 1 as the bottom plate 4 increases or decreases. After aligning the height of the cutting edge with the center of rotation of the main spindle of the lathe, fix the bottom plate holding fitting together with the cutting tool to the tool post and perform the desired cutting operation.

Next, when the use of the cutting tool 3 is finished and it is removed, the bottom plate 4 used for this is in close contact with the cutting tool 3 together with the L-shaped fitting 1 by the magnet 2.
If you store this in the rear sorting table, part-time job 3 and L
The shaped metal fitting 1 does not separate or collapse.

In addition, when using Bit 3 again, it is only necessary to attach it to the turret on its side without adjusting the height of the cutting edge, which significantly reduces the installation time in lathe machining of small quantities and a wide variety of products where the cutting tool is frequently replaced. can be shortened to
