Abstract
The present invention relates to a kind of fixtures of vacuum pump rotor CNC processing.The fixture includes the left positioning device being arranged on the left of vacuum pump rotor and the right positioning device being arranged on the right side of vacuum pump rotor, the left positioning device includes high-precision pole, supporting table, described supporting table one end is spliced in high accuracy circular nose, the other end is imitative type circular bosses, the imitative type boss edge of table is imitative type chamfering, the supporting table surface symmetrically splices bilateral flat boss, and boss circular arc is arranged on the bilateral flat boss；The right positioning device includes imitative type boss, support round platform and Morse's taper, and coarse positioning round platform and fine positioning round platform is respectively set in the imitative type boss surface, and the Morse's taper is fixed at support round platform front end.The configuration of the present invention is simple, accurate positioning, raising machining accuracy, rotor size is stable, lose circle less, product qualification rate is high, process capability is good, service life is long.
Description
Technical field
The present invention relates to a kind of vacuum pump rotor finishing positioning fixture more particularly to a kind of vacuum pump rotor CNC processing
Fixture.
Background technology
Currently, existing vacuum pump rotor clamp for machining, there are position inaccurate, the cumbersome problem of clamping is easy to lead in this way
Vacuum pump rotor is caused to be easy to lose circle in process, size is unstable, and product qualification rate is low, increases the consumption of raw material,
Process capability is low, while the service life of fixture itself is relatively low, adds additional production cost.
Invention content
The present invention provides one kind simple in structure, accurate positioning, improves machining accuracy, rotor ruler in order to solve problem above
Very little stabilization, mistake circle are less, product qualification rate is high, process capability is good, the fixture of vacuum pump rotor CNC with long service life processing.
The technical scheme is that：The fixture includes the left positioning device being arranged on the left of vacuum pump rotor and sets
The right positioning device on the right side of vacuum pump rotor is set,
The left positioning device includes high-precision pole, supporting table, and described supporting table one end is spliced before high-precision pole
End, the other end are imitative type circular bosses, and the imitative type boss edge of table is imitative type chamfering, and the supporting table surface symmetrically splices
Boss circular arc is arranged on the bilateral flat boss for bilateral flat boss；
The right positioning device includes that imitative type boss, support round platform and Morse's taper, the imitative type boss surface are set respectively
Coarse positioning round platform and fine positioning round platform are set, the Morse's taper is fixed at support round platform front end.
The configuration of the present invention is simple, accurate positioning, raising machining accuracy, rotor size is stable, loses circle less, product qualification rate
Height, process capability is good, service life is long, and rotor size tolerance can reach ± 0.01；Angle tolerance reaches ± 0.2 °；Verticality
Tolerance, symmetry tolerance reach 0.015；Total run-out tolerance reaches 0.02；Fully meet product drawing requirement, process capability CPK
≥1.67；The tooling service life reaches 200,000 products.
Description of the drawings
Fig. 1 is the assembling schematic diagram of the present invention.
Fig. 2 is the structural schematic diagram of left positioning device.
Fig. 3 is the structural schematic diagram of right positioning device.
1 is left positioning device in figure, and 2 be right positioning device, and 3 be rotor, and 4 be high-precision pole, and 5 be supporting table, and 6 be imitative
Type circular bosses, 7 be bilateral flat boss, and 8 be imitative type boss, and 9 be support round platform, and 10 be Morse's taper, and 11 be coarse positioning round platform,
12 be fine positioning round platform.
Specific implementation mode
A kind of fixture of vacuum pump rotor CNC processing, the fixture include being arranged to determine on the left side in 3 left side of vacuum pump rotor
Position device 1 and the right positioning device 2 being arranged on the right side of vacuum pump rotor 3,
The left positioning device 1 makes according to mould and die accuracy, including high-precision pole 4, supporting table 5, the supporting table 5 one
In 4 front end of high-precision pole, the other end is imitative type circular bosses 6 for end mounting, and imitative 6 edge of type circular bosses is imitative type chamfering,
5 surface of supporting table symmetrically splices bilateral flat boss 7, and boss circular arc is arranged on the bilateral flat boss 7；
The right positioning device 2 makes according to mould and die accuracy, including imitative type boss 8, support round platform 5 and Morse's taper 10, institute
Coarse positioning round platform 11 and fine positioning round platform 12, the Morse's taper 10 fixed setting is respectively set in imitative 8 surface of type boss stated
In 9 front end of support round platform.
When using the present invention, first the boring three-jaw on CNC lathe three-claw chucks, ensures three-jaw clamping center and lathe center
With one heart, left positioning device 1 is clamped in three-jaw again, and right positioning device 2 is put into the MT4 high speed centre holes of the servo tailstock of CNC lathes
It is interior, product clamping is carried out, high-precision turning is then carried out；To carry out batch high-precision machining production.
