A kind of motor case drilling machine
The invention belongs to motor manufacturing equipment technical fields, are related to a kind of motor case drilling machine.
In the part of motor production, motor housing generally includes casing and lid, and lid is divided into front cover and rear cover, motor
Casing and front cover and rear cover be all detachably connected, the parts such as stator rotor can be packed into motor case after lid disassembly
Or motor inside is repaired, the connection type between casing and lid is usually connected by screw and nut and is fastened, institute
To need to drill out connecting hole in the junction of casing, the connecting hole of usual casing and lid is all that even circumferential is arranged, and extremely
Connecting hole at rare 4, so multiple bore process need to be carried out to casing.In this process, people mostly use drilling machine complete
At, if but once bore a hole and then need to convert the station of drill bit, what is drilled in this way is inefficient, but if using multiple
Drill bit drills simultaneously, but processes the same part since drill bit is in different positions in this way, produces between drill bit and workpiece
Many places vibroseis will reduce borehole accuracy, or can control drill bit using digital control system and be moved to different stations,
But need to be added to control the mobile digital control system of drill bit in this way, it will increase the cost of machine.
