Description
Technical field
The present invention relates to a kind of vacuum pump rotor finish turning lathe more particularly to a kind of vacuum pump rotor CNC lathe for machining.
Background technology
Currently, existing vacuum pump rotor is in processing, there are position inaccurates, the cumbersome problem of clamping to be 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, vacuum pump rotor CNC lathe for machining with long service life.
The technical scheme is that：The lathe includes main shaft, chuck, three-jaw, servo tailstock, is arranged in vacuum pump
Left positioning device on the left of 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, 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；
Described high-precision pole one end is fixedly connected in chuck, and described Morse's taper one end is fixed on servo tailstock
In MT4 high speed centre holes.
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.

Specific implementation mode
A kind of vacuum pump rotor CNC lathe for machining, the lathe include main shaft 13, chuck 14, three-jaw, servo tailstock
15, left positioning device 1 on the left of vacuum pump rotor 3 is set and the right positioning device 2 on 3 right side of vacuum pump rotor is set,
The left positioning device includes high-precision pole 4, supporting table 5, and described 5 one end of supporting table is spliced in high-precision pole
4 front ends, the other end are imitative type circular bosses 6, and imitative 6 edge of type circular bosses is imitative type chamfering, 5 surface pair of supporting table
Claim mounting bilateral flat boss 7, boss circular arc is set on the bilateral flat boss 7；
The right positioning device 2 includes imitative type boss 8, support round platform 9 and Morse's taper 10, imitative 8 surface of type boss
Coarse positioning round platform 11 and fine positioning round platform 12 is respectively set, the Morse's taper 10 is fixed at 9 front end of support round platform；
Described 4 one end of high-precision pole is fixedly connected in chuck 14, and described 10 one end of Morse's taper is fixed on servo tail
In the MT4 high speed centre holes of seat 15.
When using the present invention, first the boring three-jaw on CNC lathe three-claws chuck 14, ensures in three-jaw clamping center and lathe
The heart is concentric, and left positioning device 1 is clamped in three-jaw again, and the MT4 high speeds that right positioning device 2 is put into the servo tailstock 15 of CNC lathes are pushed up
In pin hole, product clamping is carried out, then carries out high-precision turning；To carry out batch high-precision machining production.
