Background technology
Mechanical drive mode speed traditional at present promotes close to the limit, brings a lot of problem at high speed, and as high in noise, frictional dissipation height, energy loss are big etc.；Conventional mechanical transmission exists gap, elastic deformation etc. in precision much affects the link of precision, and numerous parts foozle accumulates and directly makes the precision of complete machine reduce；Conventional mechanical transmission mode needs multiple drive mechanism cooperating, and wear extent is very big, and a lot of drive disk assemblies are consumable accessory, need frequent maintenance to change, and new parts also need to certain time break-in, directly affect equipment life.
Summary of the invention
In order to overcome, existing conventional mechanical transmission mode frictional dissipation is big, precision is low, the flimsy deficiency of parts, the present invention provides a kind of high pulling torque direct drive of torque motor workbench, this high pulling torque direct drive of torque motor workbench can improve transmission speed and complete machine precision, and frictional dissipation is little, parts are hardly damaged, the extension device life-span.
The technical scheme is that a kind of high pulling torque direct drive of torque motor workbench, including workbench, workbench main shaft, table base, described workbench main shaft is connected on table base, workbench main shaft is outside to be connected with being connected seat by cylindrical roller bearing, connect seat to be connected with torque motor rotor by fixing bolt and transmit moment of torsion, torque motor rotor exterior is provided with torque motor stator, and torque motor stator is fixed on table base；Described connection seat top is connected with workbenchAnd drive worktable rotary, connect and be provided with single direction thrust ball bearing between seat bottom portion and table base.
There is advantages that owing to taking such scheme, this workbench eliminates gearbox gear gear ring drive mechanism, adopts torque motor directly to drive, and simple in construction is easy to operate；Owing to there is no reducing gear, eliminate gap, it is thus possible to the response speed of drive system, Steady speed and position control accuracy are significantly increased；Cancel the lubrication of the driving parts such as gear drive and bearing, reduce sound pollution and oil pollution；Wear and tear little, improve the lathe life-span；Dynamic property is good, and Mean Time Between Failures is long, and required maintenance is few；Super large scope stepless time adjustment, rotating speed of table 0.02 260r/min speed governing reaches 1.3 ten thousand times, main cutting transmission (260r/min) under high rotating speed can be realized, the slow-speed of revolution (0.02r/min) gapless index feed can be realized again, it is achieved multifunctional intellectual manufacture.
Accompanying drawing explanation

1-attachment screw in figure, 2-connects seat, 3-torque motor rotor, 4-torque motor stator, 5-single direction thrust ball bearing, 6-single direction thrust ball bearing, 7-workbench, 8-cylindrical roller bearing, 9-workbench main shaft, 10-table base.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of high pulling torque direct drive of torque motor workbench, including workbench 7, workbench main shaft 9, table base 10, described workbench main shaft 9 is connected on table base 10, workbench main shaft 9 is outside to be connected with being connected seat 2 by cylindrical roller bearing 8, connects seat 2 top and is connected with workbench 7 by single direction thrust ball bearing 5.EvenBy fixing boltIt is connected with torque motor rotor 3Transmission moment of torsion, torque motor rotor 3 is provided externally with torque motor stator 4, and torque motor stator 4 is fixed on table base 10. connect bottom seat 2 and between table base 10, be provided with single direction thrust ball bearing, connecting seat 2Top with Workbench 7 is connected and drives workbench 7 to rotate.
The torque motor of this workbench is a kind of brushless, permanently synchronous motor, and it is substantially the servomotor of low-speed big, owing to load is directly connected to rotor, it is not necessary to any driving member, and therefore torque motor belongs to direct driving.During workbench work, torque motor rotor directly drive workbench to connect seat 2 and rotate, thus driving workbench 7 to rotate.
Digit Control Machine Tool direct drive of torque motor turntable important technological parameters:
Maximum machining diameter: 1600mm
Maximum machining height: 1400mm
Maximum workpiece weight: 8 tons
Workbench peak torque: 16000Nm
Milling maximum speed: 2000r/min
Rotating speed of table scope: 0.02 260r/min

C axle repetitive positioning accuracy: 2 ".
High pulling torque direct drive of torque motor workbench has the advantage that
1., super large scope stepless time adjustment, rotating speed of table 0.02 260r/min speed governing reaches 1.3 ten thousand times, main cutting transmission (260r/min) under high rotating speed can be realized, the slow-speed of revolution (0.02r/min) gapless index feed can be realized again, it is achieved multifunctional intellectual manufacture.
Directly drive the structure that can simplify Digit Control Machine Tool drive system；Adopt torque motor directly to drive, overturned traditional design, eliminated gearbox gear gear ring drive mechanism, simple in construction, easy to operate, it is achieved that main transmission gapless, noiseless, it is achieved that efficiently, high reliability.
2. because not having reducing gear, the factors such as gap are eliminated, it is thus possible to the response speed of drive system, Steady speed and position control accuracy are significantly increased；
3. cancel the driving parts such as gear drive and bearing lubrication, it is achieved that energy-conserving and environment-protective, noiseless, friction, without greasy dirt, environmental protection.
4. without abrasion, non-maintaining, improve the lathe life-span.
5. dynamic property is good, and Mean Time Between Failures is long, and required maintenance is few.
