Description
Technical field
The invention belongs to technical field of mechanical transmission, more particularly to a kind of workpieces processing cyclone milling head.
Background technology
Cyclone milling head part in the market typically passes through belt drive using normal asynchronous or servomotor
Milling cutter disc spins process, the cyclone milling head of this drive form it is complicated, volume and weight is larger, when to workpiece milling
Easily vibrate, noise is big, and cutting speed is relatively low, influences the surface quality and processing efficiency of workpiece.It is added in order to ensure
The lead angle of work screw thread, when processing screw thread, facing cutter is needed to deflect an angle cyclone milling head, and the angle will be with being processed
The lead angle of screw thread is identical, and at present at home, the size of facing cutter deflection angle is typically observed by scale, and precision is not high, such as
Deviation goes beyond the scope, and milling cutter will produce interference milling in milling, and it is incorrect to make to mill out the screw thread come, therefore, traditional rotation
Wind milling head is mostly only applicable to the roughing and semifinishing of the not high workpiece of requirement on machining accuracy or ball-screw.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art and provide it is a kind of it is simple in construction, rotating speed is high, makes an uproar
The workpieces processing cyclone milling head that sound is small, machining accuracy is high.
The object of the present invention is achieved like this:A kind of workpieces processing cyclone milling head, including whirling mill headstock, fixation
The support of bearing on whirling mill headstock is provided with the milling head main shaft of through hole with center, it is characterised in that：On described milling head main shaft
A pair of bearings is installed, bearing inner race is compressed by bearing gland, and bearing outer ring is arranged on the support of bearing, milling head front-end of spindle
Quick change cutterhead is installed in taper hole, torque motor stator, milling head main shaft are fixed with by torque motor gland on whirling mill headstock
On be provided with torque motor rotor.
Taper hole is provided with the described support of bearing.
Described whirling mill headstock is arranged on milling head upper bracket and milling head lower carriage by support shaft.
Servomotor is installed on described milling head upper bracket.
Swing locking cylinder is installed on described milling head lower carriage.
Encoder is provided with described milling head main shaft.
Compared to the prior art the technology of the present invention, simplifies structure, shorten driving-chain, and volume becomes more compact, avoided
Elasticity, gap, friction and hysteresis caused by transmission parts, permanent torque output can be achieved, there is high rotating speed, low inertia
Feature, acceleration is excellent, operates steadily, noise is small, precision is high, and applicability is wide, safe.
