Document Type and Number:
Japanese Patent JPWO2021177388
Kind Code:
A1
Abstract:
In a tool holding portion of a machining tool, a cartridge is provided so as to be movable forward and backward. A cam accommodated inside a cam accommodation portion rotates while the cam is in abutment against the cartridge to thereby move the cartridge forward and backward. A rod which moves forward and backward inside a tool body along an axis is provided with an abutment portion. The abutment portion abuts against an abutment position of the cam according to the forward and backward movement of the rod to thereby rotate the cam. A restriction mechanism is capable of adjusting the phase of the cam when the abutment portion is apart from the abutment position so that a reference position is reached where the abutment position faces the abutment portion.
