6 coaxial sleeve of external seal body be set to the outside of ontology 3 and with the radially secure connection of ontology 3, at fixture and shell 1
When stationary state, 11 end of mounting hole is radially close to external seal body 6 and ringfeder 52, and mounting hole 11, ringfeder 52, ontology
Along axial there is gap to form chip space 61 between 3 and external seal body 6；The junction of the ontology 3 and external seal body 6 is chip removal
The minimum point of slot 61, in junction, external seal body 6 flushes or slightly lower with ontology 3, so that it is guaranteed that machining chips can be from ontology 3
It moves on external seal body 6, external seal body 6 is circumferentially arranged at least one and the naturally downward transition of 61 minimum point of chip space
Chip removal mouth 62.
In fixed shell 1, push rod 51 is pushed away into ontology 3 along axial direction first, ringfeder 52 follows push rod 51 to move, by ontology
3 are inserted into mounting hole 11 axially movable, and the inner wall of ringfeder 52 and mounting hole 11 has certain interval, external seal body 6 and peace at this time
It fills hole 11 to complete after cooperating, push rod 51 is returned to axially movable with ontology 3 along the position being axially close to, and ringfeder 52 is and then downward
Movement, since ringfeder 52 is wedge structure, ringfeder 52 gradually can radially hold out against the inner wall of mounting hole 11, be moved by ringfeder 52
Fill up the space between mounting hole 11 and ontology 3, when fixture and 1 clamping engagement of shell.
In preferred embodiment, ringfeder 52 is projected radially inward close to the side of shell 1 and is fastened in push rod 51, thus with
Axially movable with push rod 51.
In order to ensure the fit quality of fixture and shell 1 when every task, fixture provided in this embodiment is also to mating surface
Airtight detection is carried out, the air tightness detection machine structure 7 includes coaxial arrangement in the distributing ring 71 in 6 outside of external seal body, distributing ring 71
It is disposed radially an air inlet 72, air inlet 72 radially gos deep into external seal body 6；External seal body 6 and fixation hole 11
Mating surface on be uniformly arranged in the circumferential direction multiple stomata (not shown), the stomata passes through the channel that is hidden in external seal body 6
It is connected to air inlet.
Air pressure is provided for fixture by air inlet 72 after the assembly is completed in ontology 3 and shell 1, if air pressure can stablize
Certain value then illustrates external seal body 6 and 11 no-float of fixation hole, can be normally carried out processing, if atmospheric pressure value is not obvious
Increase, then illustrates a certain contact surface there are gap, this may be caused by falling in the clast of chucking surface after being processed as front, can
The bias that can lead to 1 axial direction of fixture and shell, influences machining accuracy, needs to remove ontology 3 and cleared up.It is completed in normal process
Afterwards, when fixture is separated with shell 1, high pressure gas can be blown out from stomata, the clast on shell 1 and fixture be blown off, to prevent
There are clasts on the contact surface of fixture and shell 1.
In order to ensure the sealing performance of distributing ring 71, it is outer that insertion is provided on the contact surface of external seal body 6 and distributing ring 71
Sealing ring 63 inside seal 6, distributing ring 71 are equipped with the bulge loop 73 being inserted into sealing ring 63；It is of course also possible to will
Sealing ring 63 is arranged on distributing ring 71, and bulge loop 73 is arranged on outer seal 6.
Distributing ring 71 itself is radially affixed with external seal body 6, its contact surface can be made to be close to realize airtight, preferred implementation
A circle and distributing ring 71 are also provided in example on the outside of outer seal 6 along the dustproof cover 74 axially engaged, dustproof cover 74 is radially
Affixed with external seal body 6, dustproof cover 74 is in concave-convex staggered labyrinth structure along axial contact surface with distributing ring 71, is further mentioned
High sealing performance, certain labyrinth structure also can choose waveform, zigzag etc..Dustproof cover is set as on the outside of 74 upper surface
The inclined-plane tilted down, consequently facilitating clast is discharged.
For the ease of test air-tightness, looping pit is enclosed circumferentially arranged with one in the end of air inlet 72 inside external seal body 6
(not shown) is circumferentially uniformly provided with inside external seal body 6 and multiple at least to match from looping pit to external seal body 6 with mounting hole 11
The gas distribution channels 64 of conjunction face place connection.
In the present embodiment, when the fixed shell 1 of fixture, the axial both ends of external seal body 6 respectively with ontology 3 and fixation hole 11
End face abuts, for the ease of processing, the gas distribution channels 64 axially through external seal body 6, and stomata be in external seal body 6 and
Fixation hole 11 is along the end face axially engaged.Since external seal body 6 and ontology 3 are along axial affixed, gas will not be from outer close
The contact surface for sealing body 6 and ontology 3 leaks, and external seal body 6 and mounting hole 11 are relatively narrow along axial counterface, only need to guarantee this
The air-tightness of end face is good, so that it may confirm fixture and 1 no-float of shell.
After confirmation air-tightness meets the requirements, can by rolling center 4 along axially pressing against 11 other side of mounting hole, thus
Shell 1 is locked, prevents from shaking when processing.
