Large bridge-type CNC gantry milling machines are designed for CNC machining of medium to large-sized mechanical parts, CNC machining of parts with high precision in hole systems and external dimensions, and CNC machining of complex three-dimensional curved surface parts.

[0003] However, existing CNC gantry milling machines often lack specialized tools when encountering deep hole grooves or internal spiral grooves, making it impossible to meet product processing requirements. When it is necessary to create a positioning groove for the inner sleeve of an external clamping sleeve, the machining device cannot be equipped with a suitable milling cutter to mill a positioning groove on the inside of the sleeve. Therefore, a machining device for creating positioning grooves on the inner sleeve of an external clamping sleeve is needed. Utility Model Content

[0024] The device for machining the inner sleeve positioning groove of the outer sleeve provided by this utility model has a fixing mechanism. When the control plate is moved to the left, the fixing rod is disengaged from the fixing hole. At the same time, the retaining spring extends. After the milling cutter head is placed in the mounting groove, the control of the control plate is released. Under the action of the retaining spring itself, the fixing rod is inserted into the fixing hole to fix the milling cutter head. This prevents the milling cutter head from disengaging from the mounting groove during machining and ensures the smooth progress of the machining work. Attached Figure Description
