Embodiment Construction
[0014] The following is based on figure 1 Shown, the present invention is further analyzed: as figure 1 As shown, a quick-change countersinking device and method is composed of a guide mandrel 1, a quick-change tool 2, a gasket 3, a pressure bolt 4 and a tool handle 5. Both the working end and the fixed end of the handle are provided with internal threads; the pressure bolt 4 runs through the gasket 3, the guide mandrel 1, the quick-change tool 2, and the handle 5 in turn, and is tightly connected with the working end of the handle 5; the guide The mandrel 1 and the quick-change tool 2 are cylindrical in shape; both sides of the quick-change tool 2 are respectively connected with the handle 5 and the guide mandrel 1 by crimping. The buckle connection can play the role of applying force to the CNC lathe to achieve integral rotation and transmit torque. The outer surface of the cylindrical quick-change tool is provided with a lateral groove 6; an indexable insert 7 is arranged...

The invention relates to a quick-changing type counter boring device and a quick-changing type counter boring method. The device comprises a guiding spindle, a quick-changing tool, a gasket, a pressure bolt and a knife handle. Both the working end and the fixed end of the knife handle are provided with inner screws; the pressure bolt penetrates through the gasket, the guiding spindle, the quick-changing tool and the knife handle sequentially and is fixedly connected with the working end of the knife handle; the guiding spindle and the quick-changing tool are of hollow cylinder type; two sides of the quick-changing tool are connected with the knife handle and the guiding spindle respectively by withholding. The outer surface of the cylindrical quick-changing tool is provided with a lateral groove; a rotatable blade is arranged in the groove. The device and the method have the following beneficial effects: the process cycle is short, the efficiency is high and the dangerousness is low in use, the device and the method are suitable for the machining of a multi-aperture and multi-diameter counter boring plane, the locating and cutting of the tool can be realized by changing the diameter of the guiding spindle and the tool, so as to realize the quick-changing function, and therefore, the universality and the interchangeability are improved.
Description
technical field [0001] The invention relates to a device and a countersinking method for processing a countersinking hole on a conical surface of a mill, especially a large-scale mills cone, in particular to a quick-change countersinking device and method, which belong to the technical field of mechanical processing. technical background [0002] During mill processing, some mills need to countersink the mill liner hole on the outer surface by machining, so as to install bolts and gaskets during engineering use. At present, most of the methods used in the industry are boring and milling machines or gantry milling machines to process counterbores. This processing method is acceptable for mills with a diameter of less than 5 meters and a weight of less than 30 tons, but for mills with a diameter of more than 5 meters, Due to the insufficient span of the gantry milling machine, the existing technology can only be processed on the boring and milling machine. Due to the limitatio...
