A kind of motor case efficient drilling machineTechnical field
The utility model belongs to motor manufacturing equipment technical field, is related to a kind of motor case efficient drilling machine.
Background technology
In the part of motor production, motor housing generally includes casing and lid, and lid is divided into protecgulum and bonnet, motorCasing and protecgulum and bonnet be all detachably connected, can load the parts such as stator rotor in motor case after lid dismountingOr motor internal is repaired, the connected mode between casing and lid is generally connected by screw and nut and fastened, instituteTo need the junction in casing to get out connecting hole, the connecting hole of usual casing and lid is all even circumferential arrangement, and extremelyConnecting hole at rare 4, so multiple bore process need to be carried out to casing.In this process, more than people using rig come completeInto, but then need to become the station of bit change if once boring a hole, so drilling is inefficient, but if using multipleDrill bit drills simultaneously, so because drill bit but processes same part in different positions, is generated between drill bit and workpieceMany places vibroseis, will be reduced to borehole accuracy, or drill bit can be controlled to move to different stations using digital control system,But so need to add the digital control system for being used to control drill bit to move, it will increase the cost of machine.
