Description
Technical field
This utility model relates to lathe, is specifically related to the air supporting lathe of outer rotor motor driven.
Background technology
Currently, precision machine tool is at Aero-Space, war industry, precision instrument, optics and photoelectric communication, microelectronics, new energy
Numerous high-tech sector such as source, biomedical engineering plays huge effect day by day.But, in existing precision machine tool uses
Rotor electric machine drives, and its structure is complicated, smoothness of operation is poor, process velocity is slow, then affects workpiece processing quality and adds work efficiency
Rate；And frictional force and the noise between rotary part adds that the most greatly the rigidity of machine tool is not high enough, causes the service life of lathe
Short.
Utility model content
In order to overcome drawbacks described above in prior art, the purpose of this utility model be to provide a kind of simple and compact for structure,
Smooth running, efficiency are high, frictional force and the air supporting lathe of noise is little, rigidity is high outer rotor motor driven.
To achieve these goals, this utility model by the following technical solutions: the air supporting lathe of outer rotor motor driven,
Including base, arrange on the base support seat, the external rotor electric machine being arranged on this support seat, by swivel joint and the end
The workbench that seat connects, described external rotor electric machine includes stator core, the stator winding being arranged on this stator core, sets successively
Put the magnet steel outside this stator winding and rotor；This rotor is connected with outer rotor, between outer rotor and workbench
Being provided with air-bearing, these air-bearing both sides are vertically arranged with main gas passage, main gas passage and some points of gas channel connections, gas
Floating axle holds and is provided with shading ring outside point gas passage on top.
Described swivel joint by shell, be arranged in this shell determine core, be arranged on and determine the dynamic core of core upper end, be arranged on this
The spring of dynamic core upper end is constituted, and shell is attached by bearing with determining core.
Compared with prior art, this utility model is owing to using above technical scheme, and workbench is supported by air-bearing, real
Having showed motor and workbench integral structure, outside air supply system is made to workbench supply with point gas passage by main gas passage
Workbench can suspend, and can reduce the frictional force between rotary part and noise, the resistance to compression of raising workbench to greatest extent
Ability namely improves the rigidity of workbench, and frictional force diminishes, and process velocity response improves；Second, employing swivel joint will
Workbench is attached with base, and when workbench rotates, shell, spring, dynamic core and bearing rotate together with workbench, determine core
Keep resting state with base, while improve the stationarity of operating, ensure that crudy, reach ultraprecise processing and want
Ask；In a word, this utility model has the advantages such as rigidity simple and compact for structure, high, smooth running, efficiency is high, noise is little.

Motor includes stator core 7, be arranged on this stator core stator winding 6, it is successively set on the magnetic outside this stator winding
Steel 5 and rotor 4；This rotor is connected with outer rotor 8；In order to reduce frictional force, set between outer rotor 8 and workbench 10
Being equipped with air-bearing 9, these air-bearing both sides are vertically arranged with main gas passage 12, and main gas passage 12 is with some points of gas passages 13 even
Logical, outside air supply system makes workbench can suspend with point gas passage 13 to workbench 10 supply by main gas passage 12；For
Prevent gas from leaking outside, outside point gas passage on air-bearing 9 top, be provided with shading ring 11.
In order to improve the stationarity of machine tool running, described swivel joint 2 by shell 18, be arranged in this shell determine core
14, the spring 17 be arranged on the dynamic core 16 determining core upper end, being arranged on this dynamic core upper end is constituted, shell 18 with determine core 14 and pass through bearing
15 are attached.When workbench rotates under the driving of motor, the shell 18 of swivel joint 2, spring 17, dynamic core 16 and
Bearing 14 rotates together with workbench, determines core 14 and keeps resting state with base 1 and support seat 3.
