Embodiment Construction
[0019] Such as figure 1 , figure 2 As shown, the milling cutter 5 is clamped on the spindle bearing seat 4 of the end milling head with a circlip 17 and a collet 18. Circular transition fit can play the role of pin hole positioning, ensuring the coaxiality accuracy of the center axis of the fixture and the spindle of the end milling head; Close on the bed 1 of the end milling head, the flange connecting sleeve 20 is welded on the fixed bracket 19, which ensures the firmness of the milling cutter installation, and ensures that the fixed bracket 19 is directly behind the CNC end milling machine table; the milling cutter 5 according to According to the needs of crankshaft processing, it is designed as a special milling cutter to ensure that it does not interfere with the journal of the crankshaft keyway when milling the keyway. When the milling cutter 5 is clamped by the circlip 17, there is a stepped shaft for positioning to ensure that the top 6 is tight. , the axial positio...
