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
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.
