Drill bit mounting structure that machining changed with being convenient for

The utility model relates to machining equipment technical field, concretely relates to drill bit mounting structure that machining changed with being convenient for for install the drill bit in the rig fuselage, including the electromagnetic type adapter sleeve, the electromagnetic type adapter sleeve is fixed locates the rig fuselage, is equipped with the mo shi taper hole on the electromagnetictype adapter sleeve, connect the conical head, the connection conical head passes through the pyramis to be connected with the mo shi taper hole, and the pyramis of connecting the conical head is themoshi pyramis. The beneficial effects are that: through electromagnetic type adapter sleeve that use to connect the conical head with have the mo shi taper hole, the replacement and installation of the drill bit of being convenient for simultaneously, uses solenoid to increase and connects joint strength between conical head and the moshi taper hole, has guaranteed the reliable connection of connecting conical head and mo
