Description

A kind of high pulling torque direct drive of torque motor workbench

Technical field

This utility model relates to mechanical field, a kind of high pulling torque direct drive of torque motor workbench.

Background technology

The most traditional mechanical drive mode speed promotes close to the limit, brings a lot of problem at high speed, as high in noise, Frictional dissipation height, energy loss are big etc.;Conventional mechanical transmission exists gap, elastic deformation etc. in precision much affects precision Link, numerous parts foozle accumulates and directly makes the precision of complete machine reduce;Conventional mechanical transmission mode needs multiple Drive mechanism cooperating, 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 Want 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, this Utility model provides a kind of high pulling torque direct drive of torque motor workbench, and this high pulling torque direct drive of torque motor workbench can improve High transmission speed and complete machine precision, and frictional dissipation is little, parts are hardly damaged, the extension device life-span.

The technical solution of the utility model is: 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, passes through short columnar roller outside workbench main shaft Bearing connects with being connected seat, connects seat and is connected with torque motor rotor by fixing bolt and transmits moment of torsion, torque motor rotor Outside is provided with torque motor stator, and torque motor stator is fixed on table base;Described connection seat top and workbench It is connected and drives worktable rotary, connecting and be provided with single direction thrust ball bearing between seat bottom portion and table base.

This utility model has the advantages that, owing to taking such scheme, this workbench eliminates gearbox gear Wheel gear ring drive mechanism, uses torque motor directly to drive, and simple in construction is easy to operate;Owing to there is no reducing gear, disappear Except 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, reduces sound pollution and oil pollution;Wear and tear little, improve the lathe longevity Life;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, can realize main cutting transmission (260r/min) under high rotating speed, can realize again The slow-speed of revolution (0.02r/min) gapless index feed, it is achieved multifunctional intellectual manufacture.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

1-attachment screw in figure, 2-connects seat, 3-torque motor rotor, 4-torque motor stator, 5-one-way thrust ball axle Hold, 6-single direction thrust ball bearing, 7-workbench, 8-cylindrical roller bearing, 9-workbench main shaft, 10-table base.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings:

As shown in Figure 1, a kind of high pulling torque direct drive of torque motor workbench, including workbench 7, workbench main shaft 9, workbench Base 10, described workbench main shaft 9 is connected on table base 10, and workbench main shaft 9 is outside by cylindrical roller bearing 8 Connect with being connected seat 2, connect seat 2 top and be connected with workbench 7 by single direction thrust ball bearing 5.Connect seat 2 by fixing bolt Be connected transmission moment of torsion with torque motor rotor 3, torque motor rotor 3 is outside is provided with torque motor stator 4, and torque motor stator 4 are fixed on table base 10. and connect bottom seat 2 and between table base 10, be provided with single direction thrust ball bearing, connecting seat 2 Top is connected with workbench 7 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 servo electricity of low-speed big Motivation, owing to load is directly connected to rotor, it is not necessary to any driving member, therefore torque motor belongs to directly driving.Workbench work When making, torque motor rotor directly drive workbench to connect seat 2 and rotate, thus drive 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

Rotating speed of table progression: stepless

C axle positioning precision: 4 "

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, can realize Main cutting transmission (260r/min) under high rotating speed, can realize again the slow-speed of revolution (0.02r/min) gapless index feed, it is achieved many merits Can intelligence manufacture.

Directly drive the structure that can simplify Digit Control Machine Tool drive system;Use torque motor directly to drive, overturn biography System design, eliminates gearbox gear gear ring drive mechanism, and simple in construction is easy to operate, it is achieved that main transmission gapless, nothing Noise, it is achieved that efficient, high reliability.

2. because not having reducing gear, the factors such as gap are eliminated, it is thus possible to the sound of drive system is significantly increased Answer speed, Steady speed and position control accuracy;

3. the lubrication of the driving parts such as gear drive and bearing is cancelled, it is achieved that energy-conserving and environment-protective, noiseless, nothing are shaken Dynamic, 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.
