Nut 11 carries out rotation connection with the lead screw 10 being fixed among support platform 9.When manual rotating nut 11, lead screw will band
Guide rail 13,14 in left and right sliding is moved to ramp or decline, it, can be by left and right when rising or decline certain altitude requires
Stud base is pressed in interior guide rail by sliding outer guide 18, the left rail fastening bolt 15 of 20 two sides and right guide rail fastening bolt 16
In locking slot, axially position is realized, and guarantee solid and reliable property of workpiece when on fixture in processing.
In adsorbent equipment, the present embodiment shares the identical Suction cup assembly of 2 nested structures, and it is flat that Suction cup assembly is uniformly mounted on support
On platform 9, in every set Suction cup assembly, first sealing ring 19 is mounted in sucker base 2, then sucker 1 is mounted on sucker base 2
In, prevent absorption when occur gas leak phenomenon and cause to adsorb it is unreliable.The end rubber disc mouth of sucker 1 is than on sucker base
Surface is higher by a certain distance, so that being located on sucker base when workpiece is adsorbed, while sucker 1 can be adjusted with support base
Angle adsorbs carbon fibre composite plate.And it is connect by the stay bolt of 1 lower end of sucker with the threaded hole 6a of support base 6 solid
It is fixed.There is stomata among sucker, sucker lower end is connect by air intake duct with external vacuum pump, and sucker can be by carbon when vacuum pump work
The upper surface that fibrous composite plate is adsorbed on sucker base achieves positioning.And then it realizes to carbon fibre composite
Milling Process.In view of single sucker forced area is small and the suction pressure of vacuum pump is limited, so on a fixture unit
It can also be used simultaneously equipped with 2-4 sucker, guarantee workpiece will not be made to rotate due to there are torque when plate milling.
Support base 6 is connect by π shape slot 6d with the flat upper end of ribs 3, by support base bolt 4 by support base 6 and
3 upper end of ribs links together, after Suction cup assembly adjusts angle, by the tight fixed bolt being mounted in ribs annular groove 3a
5 is fixed；The other end of ribs 3 is mounted in support platform 9 by fixing bolt, nut 7,8.Support base 6 and ribs 3 are logical
Cross two pairs of bolts, nut cooperation is fixed, a pair of bolts nut is used to support the hinged of seat and ribs, and another pair is used for annular groove
Place plays after the tilt angle of adjustment support base and tightens locked effect；Ribs 3 can be with 360 degree rotation to adjust absorption
Position.The upper end of ribs has fixed bolt hole and annular groove.Support base 6 can be around the axis rotation of bolt 4, when going to one
When determining angle, outer end tight fixed bolt 5 and the nut of annular groove 3a are tightened, fixed position.
The present invention adds the milling of carbon fibre composite using a set of adjustable suction jig completion by shirtsleeve operation
Adjustment in work angle and height, compared with traditional clamping device and modularization suction jig, the fixture is full-featured, flexibility
By force, using reliable, machining accuracy and processing efficiency can be improved.
