Abstract

The invention discloses a hollow turntable. A worktable 1 is fixedly connected with a mandrel 6, the mandrel 6 is fixedly connected with a torque motor rotor 7, a first screw 11 penetrates a pressing plate 20, a radial turntable bearing seat ring 5a and a turntable bearing thrust washer 5c and is fixedly connected with the mandrel 6, a pneumatic clamp 4 and the mandrel 6 are concentric, the pneumatic clamp 4 sleeves the outside of the mandrel 6 and is fixedly connected with an upper flange plate 2, the upper flange plate 2 and a torque motor stator 9 are fixedly connected with a turntable body 21, a radial turntable bearing shaft ring 5b is fixedly connected with the turntable body 21 through a second screw 11, a lower flange plate 19 is fixedly connected with the turntable body 21, and a flange sleeve 14 is fixedly connected with the lower flange plate 19. The hollow turntable has the advantages of high rotating speed, full-closed loop control and safe and environment-friendly locking mode. As the worktable is hollow, the machining range of a traditional vertical machining center can be extended to meet machining requirements of shafts or other parts with large length-diameter ratios.

Description

Hollow type turntable
Technical field
The present invention relates to a kind of hollow type turntable, particularly to a kind of lathe C axle hollow type turntable
Background technology
Turntable is the critical function parts of machining center, and its gyration and other linear axis carry out linkage and can process respectively Planting complex-curved or shaped piece, its supporting machining center has been obtained for extensively in the modern industry such as military project and Aero-Space Application.Existing turntable uses center location structure, and table core has a positioning center hole, its underpart and rotary encoder Rotating part connect.And rotary encoder is fixed on base body by encoder support, base bottom base cover plate is close Envelope.The turntable of this kind of design for some draw ratios are relatively big or length is longer but part that only local needs processing, due to Can only be installed above at work top, need to make the highest or baroque fixture and be fixed, both added processing Difficulty, have lost again the stroke (as shown in Figure 1) of linear axis.
Summary of the invention
Solved by the invention technical problem is that overcomes prior art not enough, it is provided that a kind of lathe C axle hollow type turntable.
The technical solution used in the present invention is hollow type turntable, and workbench is fixing with mandrel to be connected, mandrel and torque motor Rotor is fixing to be connected, and screw one is connected through pressing plate, the centripetal seat ring of turntable bearing and turntable bearing thrust washer and mandrel are fixing, Pneumatic gripping is concentric with mandrel, is enclosed within mandrel outer, and fixing with upper flange plate is connected, upper flange plate and torque motor divided stator Not fixing with turntable body and be connected, the centripetal blowout patche of turntable bearing is connected by screw two and turntable body are fixing, lower flange and turntable Body is fixing to be connected, and flange sleeve is fixing with lower flange to be connected.Torque motor rotor rotates, and drives central axis and workbench to turn Dynamic, the radial and axial power suffered by workbench is transmitted on turntable body by turntable bearing, and pneumatic gripping can be with lock mandrel.
Dust ring it is provided with between workbench and upper flange plate.Being provided with V-ring between mandrel and flange sleeve, turntable body lower end is pacified Capping plate.Flange sleeve offers hermetic seal passage, inside sets swollen stifled.The impurity such as these sealings are possible to prevent dust, water enter and turn Inside platform, affect precision and the service life of turntable.
Read head is fixing with lower flange to be connected.Rotation magnetic railings ruler is fixing with mandrel to be connected.Read head and rotation magnetic railings ruler It is used for C axle revolution revolution feedback is carried out magnetic grid detection.
The invention has the beneficial effects as follows the hollow type turntable of the present invention, rotating speed is high, full closed loop control, locking mode safety collar Protect.Because workbench hollow can expand the range of work of traditional vertical machining center, meet axle class or other draw ratios bigger zero The processing of part.
Accompanying drawing explanation
Fig. 1 is the turntable structure schematic diagram of prior art of the present invention;
Fig. 2 is the structural representation of the hollow type turntable of the present invention.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Hollow type turntable as shown in Figure 2, workbench 1 is fixing with mandrel 6 to be connected, and mandrel 6 is fixed with torque motor rotor 7 Connecting, screw 1 is fixing with mandrel 6 even through pressing plate 20, turntable bearing centripetal seat ring 5a and turntable bearing thrust washer 5c Connecing, pneumatic gripping 4 is concentric with mandrel 6, is enclosed within outside mandrel 6, and fixing with upper flange plate 2 is connected, and upper flange plate 2 and moment are electric Machine stator 9 is fixing with turntable body 21 respectively to be connected, and turntable bearing centripetal blowout patche 5b is fixing with turntable body 21 even by screw 2 11 Connecing, lower flange 19 is fixing with turntable body 21 to be connected, and flange sleeve 14 is fixing with lower flange 19 to be connected.Torque motor rotor turns Dynamic, drive central axis and workbench to rotate, the radial and axial power suffered by workbench is transmitted to turntable by turntable bearing On body, pneumatic gripping can be with lock mandrel.
Dust ring 3 it is provided with between workbench 1 and upper flange plate 2.V-ring 17, turntable it is provided with between mandrel 6 and flange sleeve 14 Cover plate 12 is installed in body 21 lower end.Flange sleeve 14 offers hermetic seal passage, inside sets swollen stifled 13.These sealings are possible to prevent ash Dirt, the impurity such as water enters inside turntable, affects precision and the service life of turntable.
Read head 15 is fixing with lower flange 19 to be connected.Rotation magnetic railings ruler 16 is fixing with mandrel 6 to be connected.Read head and rotation Magnetic railings ruler is used for C axle revolution revolution feedback is carried out magnetic grid detection.
The invention has the beneficial effects as follows the hollow type turntable of the present invention, rotating speed is high, full closed loop control, locking mode safety collar Protect.Because workbench hollow can expand the range of work of traditional vertical machining center, meet axle class or other draw ratios bigger zero The processing of part.
