Axial rectangular channel cooperates.Due to the head of screw of positioning screw 16（That is head column part）With the axial direction on the screw 15
Rectangular channel matches, and ensures so that the screw 15 is circumferential does not rotate but axially slidable；And then realize it is circumferentially positioned and
Axially directed effect.
Further, the roller bearing 10 includes inner ring 101 and outer ring 102, and is located at inner ring 101 and outer ring 102
Between realize the roller of rolling；
The frame is equipped with mounting hole, and the outer ring 102 of the bearing 10 is fixed on by mounting hole on the frame.
In order to avoid the sealing problem between ring flange 6 and revolving body 9, can be arranged between ring flange 6 and revolving body 9
Sealing ring 11 realizes sealing and protection to bearing 10.
For fixing bearing, the frame is equipped with mounting hole, and the outer ring 102 of the bearing 10 is fixed on by mounting hole
On the frame.
Further, ring flange 6 is additionally provided on the frame, the outer ring 102 of the roller bearing 10 passes through the first spiral shell
Nail 7 passes through ring flange 6 and mounting hole to be fixed with the frame.Bearing 10 is pressed on mounting hole by ring flange 6 by the first screw 7
Inside make its axial not play, the rotation that such revolving body 9 can freely, stable.
Further, it is moved for the ease of dismounting, the frame includes upper frame 4 and lower frame 8,4 He of upper frame
The lower frame 8 is connected by mounting screw 21.
Further, for braced frame, the lower frame 8 is connected with pedestal 3 by bolt 5.
Further, pressing plate 1 is connected with by the second screw 2 on the pedestal 3.Wherein, pressing plate 1 is for consolidating tooling
It is scheduled on above the workbench of process equipment.
Further, in order to protect the screw 15 and lead screw 17 in slide 18 and slide 18, the slide 18 to be equipped with
End cap 20.
Further, dottle pin 19 is equipped between slide 18 and the lead screw 17.By dottle pin 19, make lead screw 17 in slide
It is axially completely fixed in 18, realizes that screw 15 can way moving in slide 18.
Further, it is additionally provided with spring shim 13 between ring flange 6 and screw 17, branch is played by spring shim 13
Support the effect of clamping.
4 sets of flexible clamping devices can be respectively set on revolving body 9, constitute the revolution of complete set for the utility model
9 support system of body.A whole set of tooling is fixed on above the workbench of process equipment by pressing plate 1；Pedestal 3 is basis, plays support and consolidates
Fixed effect；Upper frame 4, lower frame 8, revolving body 9, the core component that bearing 10 is revolving structure, upper frame 4 and lower frame 8
A frame with high shock resistance and high rigidity is constituted, the mounting surface of degree of precision is provided after zoarium processing for bearing 10；
Bearing 10 is made of inner ring 101, outer ring 102 and roller, intermediate by roller support, outer ring 102 in this system
It is fixed in frame 4, the frame endoporus that lower frame 8 forms, inner ring 101 can rotate.Rolling of the bearing 10 as revolving body 9
Guide rail is part mostly important in core component, plays the role of support, revolution, guide rail, ensures precision so that revolving body
9 keep higher precision in turning course；Four sets of duplicate flexible clamping devices be distributed on the circumference of revolving body 9 with
Make rotary motion with revolving body 9, often covers and be mainly made of top 14, screw 15, positioning screw 16, lead screw 17, slide 18, other
Part is connector, and slide 18 is that the slide bearings of flexible clamping device mainly play support and provide slideway, screw
15, lead screw 17 cooperates to be mounted in slide and work under the positioning of positioning screw 16 and guiding, when lead screw 17 is revolved in outside
Screw 15 can be pushed for linear motion when rotation under torque effect, the top 14 mounted on 15 end of screw is stretched in company with screw 15
Contracting, top 14 are directly contacted with the outer circle of clamped workpiece, and four tops 14 can clamp workpiece to centre of gyration contraction, simultaneously
Loosen workpiece if negative direction.
The characteristics of tooling of the utility model is：Revolving body 9 and its telescopic device above are during the work time in company with quilt
Support workpiece does rotary motion together, because workpiece B is in the center of revolving body 9, its centre of gyration and the endoporus of workpiece
Center, the center holding of driving device are completely concentric.Since clamping device is scalable, workpiece within the scope of certain size can it is big,
It can be small.A whole set of tooling has high rigidity and high rotating accuracy, and flexible durable.
Since the part of required repair and processing is deep-hole type parts, outer circle cannot function as machining benchmark, deep hole machining
The endoporus of part needs to overlap with the centre of gyration in process, but must be supported by the deep hole machining part outer circle.This is
The centre of gyration of system is unique, and the main-shaft core with process equipment in assembling process overlaps, and passes through the clamping device that stretches
It is clamped in the center that inner hole of workpiece is adjusted on excircle of workpiece so that inner hole of workpiece center and the centre of gyration overlap.Adding
During work, by the support of the system, workpiece can keep being processed in the case that center is constant in rotary course, to
Reach final technology requirement.It solves insoluble project in deep hole machining, improves processing efficiency, reduce and be produced into
This, has saved energy consumption.
