Utility Model Registration No. 3146819

However, the above-described cutting tool localization method always requires the assistance of a localization device, and the cutting tool cannot be localized directly.
For this reason, after the localization is completed, it is usually necessary for an operator to visually confirm whether or not the blade localization of the cutting tool is reliably performed, which is very troublesome.
Not only that, but the operator's experience must be relied upon, so inexperienced workers must repeatedly adjust and localize over time.
In particular, when the cutting tool is a small cutting tool, since the blade is very small, the degree of visual judgment becomes high.
That is, the prior art has the disadvantages that the degree of localization of the cutting tool is high and the accuracy is low.

  The present invention relates to a cutting tool holder that can be directly inspected by a user and can quickly position a cutting tool.

A cutting tool holder capable of direct inspection and localization of a cutting tool according to the present invention includes a holder body, an adjustment ring, at least one tight compression member, and an inspection localization unit.
The holder body has a front nut, a rear nut, and a collet.
A conical hole is formed through the front nut. A first screw yama portion is formed on the inner wall surface of the conical hole.
A stereotaxic portion is annularly installed around the outer periphery of the front nut.
The collet is installed in the conical hole. A clamping hole corresponding to the conical hole is formed in the collet.
A second screw yama part corresponding to the first screw yama part is formed in the rear nut. As a result, the first screw yama part and the second screw yama part are screwed together, and the collet is placed between the front nut and the rear nut. The rear nut is formed with a hole corresponding to the holding hole.

The adjustment ring is installed over the fixed portion of the front nut and rotates relative to the holder body. Around the adjustment ring, at least one stereotaxic hole is formed so as to penetrate therethrough. The adjustment ring is formed by flatly cutting at least one localization surface.
At least one tight compression member is placed through the stereotaxic hole. A contact compression end is formed at the end of the tight compression member facing the stereotaxic portion. As a result, the adjustment ring is made non-rotatable relative to the holder body by tightly pressing the localization portion. An operation end is formed at the end of the tight compression member opposite to the contact compression end.

  The autostereotactic unit has a hold sheet. The hold sheet is provided with at least a pair of hold arms. Each hold arm can be fixed with an adjustment ring in between. As a result, the hold sheet rotates according to the adjustment ring. At the same time, an inspection hole corresponding to the conical hole of the front nut is further formed through the hold sheet. A stereotaxic line is installed in the viewing hole. The localization line is parallel to the localization plane. Here, the parallel means that an error that can be regarded as parallel is allowed.

With the cutting tool holder capable of direct inspection and localization of the cutting tool according to the present invention, the user first places the cutting tool between the holder body, then installs the inspection localization unit between the adjustment ring, and further turns the adjustment ring. By simply rotating the stereotaxic unit relative to the cutting tool holder in conjunction with it, the localization line can be accurately aligned with the cutting tool blade so that the cutting tool blade can also be accurately aligned with the localization surface indirectly. The localization of the cutting tool can be completed.
Thereby, the user can complete the localization of the cutting tool easily, quickly and directly at once, and the speed, accuracy and convenience of the cutting tool localization can be improved.
