Description
Technical field
It the utility model is related to a kind of vacuum pump rotor finish turning lathe, more particularly to a kind of vacuum pump rotor CNC processing
Lathe.
Background technology
At present, in processing there is the problem of position inaccurate, clamping is cumbersome in existing vacuum pump rotor, so easily lead
Vacuum pump rotor is caused easily to lose circle in process, size is unstable, and product qualification rate is low, adds the consumption of raw material,
Process capability is low, while the service life of fixture itself is relatively low, adds additional production cost.
Utility model content
The utility model provides a kind of simple in construction, accurate positioning, raising machining accuracy to solve problem above, turned
Sub- dimensionally stable, mistake circle are less, product qualification rate is high, process capability is good, the vacuum pump rotor CNC lathe for machining of service life length.
The technical solution of the utility model is：Described lathe include main shaft, chuck, three-jaw, servo tailstock, be arranged on it is true
Left positioner on the left of empty pump rotor and the right positioner being arranged on the right side of vacuum pump rotor,
Described left positioner includes high-precision pole, supporting table, and described supporting table one end is spliced in high accuracy circular
Nose, the other end are imitative type circular bosses, and described imitative type boss edge of table is imitative type chamfering, and described supporting table surface is symmetrical
Bilateral flat boss is spliced, boss circular arc is set on described bilateral flat boss；
Described right positioner includes imitative type boss, support round platform and Morse's taper, described imitative type boss surface point
Not She Zhi coarse positioning round platform and fine positioning round platform, described Morse's taper is fixedly installed on 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
MT4 high speed centre holes in.
The utility model is simple in construction, accurate positioning, improves that machining accuracy, rotor size are stable, lose circle less, product is qualified
Rate is high, process capability is good, service life length, and rotor size tolerance can reach ± 0.01；Angle tolerance reaches ± 0.2 °；Vertically
Degree tolerance, symmetry tolerance reach 0.015；Total run-out tolerance reaches 0.02；Fully meet product drawing requirement, process capability
CPK≥1.67；The frock life-span reaches 200,000 products.

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, and 13 be main shaft, and 14 be chuck, and 15 be servo tailstock.
Embodiment
A kind of vacuum pump rotor CNC lathe for machining, described lathe include main shaft 13, chuck 14, three-jaw, servo tailstock
15th, the left positioner 1 for being arranged on the left side of vacuum pump rotor 3 and the right positioner 2 for being arranged on the right side of vacuum pump rotor 3,
Described left positioner includes high-precision pole 4, supporting table 5, and described one end of supporting table 5 is spliced in high accuracy
The front end of pole 4, the other end are imitative type circular bosses 6, and the described imitative edge of type circular bosses 6 is to imitate type chamfering, the described table of supporting table 5
Face symmetrically splices bilateral flat boss 7, and boss circular arc is set on described bilateral flat boss 7；
Described right positioner 2 includes imitative type boss 8, support round platform 9 and Morse's taper 10, described imitative type boss 8
Before surface sets coarse positioning round platform 11 and fine positioning round platform 12, described Morse's taper 10 to be fixedly installed on support round platform 9 respectively
End；
Described one end of high-precision pole 4 is fixedly connected in chuck 14, and described one end of Morse's taper 10, which is fixed on, to be watched
Take in the MT4 high speed centre holes of tailstock 15.
During using the utility model, first the boring three-jaw on CNC lathe three-claws chuck 14, ensures three-jaw clamping center and machine
Bed center is concentric, and three-jaw clamps left positioner 1 again, and the MT4 that right positioner 2 is put into the servo tailstock 15 of CNC lathes is high
In fast centre hole, product clamping is carried out, then carries out high-precision turning；To carry out batch high accuracy machining production.
