Background technology
Electro spindle is a kind of to be merged into common the lathe such as main shaft of lathe, milling machine, boring machine and drilling machine etc. and spindle motor
The machine tool component of integration.
Existing machine tool chief axis is connected with spindle motor mostly using gear, shaft coupling, belt connection or other connections, but all
The problems such as gear clearance, Coupling Clearance, belt slippage, belt shake and various transmission mechanisms wear be present, next to that common
Machining center and engraving machine electro spindle working speed it is higher（8000 ~ 2400 revs/min）Moment of torsion is smaller, the carving for light load
Milling class is processed.It cannot be used for heavy load processing.
The content of the invention
It is an object of the invention to provide a kind of big torsion electric spindle motor of low speed, improved by structure to solve the above-mentioned back of the body
Problem present in scape technology.
The technical scheme is that：A kind of big torsion electric spindle motor of low speed, including electro spindle, rotor core, stator line
Winding is enclosed, electro spindle includes rotating shaft, handle of a knife pull bar, handle of a knife, it is characterised in that：Rotor core is arranged in rotating shaft, and rotating shaft is set
Hollow, handle of a knife pull bar is connected through rotating shaft with handle of a knife, and coil windings are arranged on stator, and coil windings use frequency conversion coil windings
Or servo coil winding so that it possesses maximum torsion of the permanent moment of torsion behavior in service still with motor i.e. in middle low-speed running
Square, adapt to operating mode needs when lathe low speed is high to be turned round.
A kind of further described big torsion electric spindle motor of low speed, it is characterized in that：The bearing of electro spindle is using combination
Assembling：I.e. rotating shaft one end is assemblied on body using deep groove ball bearing, and the other end uses two single-row angular contact bearings, or one
Double row angular contact bearing is installed on body, rotating shaft is born radial load and axial force for a long time so that electrical spindle for machine tool has
There is permanent accurate performance.
A kind of further described big torsion electric spindle motor of low speed, it is characterized in that：The end cap of electro spindle is than common electricity
The end cap wall thickness reinforcement of machine is more, can bear axial force and the radial direction vibrations being transmitted to by rotating shaft, the end cap of thickening
Also allow electro spindle to be fixed when being assembled to lathe by end cap, make assembling simplification and assembly precision is high, electro spindle
With height processing rigidity and high assembly precision.
A kind of further described big torsion electric spindle motor of low speed, it is characterized in that：Also include electromagnetic brake and
Spindle encoder is assemblied in rotating shaft so that electrical spindle for machine tool possesses braking and pinpoint function.
The utility model beneficial effect is：Electrical spindle for machine tool has high rigidity, high torque characteristic, is especially suitable for being used in
On the lathe that low speed and large torque, high rigidity are processed in wood-turning machine, hardware lathe, milling machine and drilling machine etc., above-mentioned lathe is substituted to set
Standby original main shaft power assembly containing transmission device so that machine tool capability is substantially improved.
The present invention directly eliminates spindle motor after machine tool chief axis is integrally combined with spindle motor and imparted power to
The transmission mechanism of main shaft.There is no transmission mechanism to avoid to be driven power consumption yet, reach than having the lathe of spindle drive more
The effect of energy-conservation, while it also avoid other common drawbacks that transmission mechanism is brought.So that it is assembled with the lathe of electrical spindle for machine tool
Operation it is more accurate, stably, efficiently and peace and quiet.In the actual use of lathe, precision and stability when machine tool chief axis is run
There is very big influence to the quality, efficiency and cutter life of processing.
