Description
Technical field
It the utility model is related to a kind of vacuum pump rotor finishing positioning fixture, more particularly to a kind of vacuum pump rotor CNC
The fixture of processing.
Background technology
At present, there is the problem of position inaccurate, clamping is cumbersome in existing vacuum pump rotor clamp for machining, 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 folder of the vacuum pump rotor CNC processing of service life length
Tool.
The technical solution of the utility model is：Described fixture includes being arranged on the left positioner on the left of vacuum pump rotor
With 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.
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.
Brief description of the drawings
Fig. 1 is assembling schematic diagram of the present utility model.
Fig. 2 is the structural representation of left positioner.
Fig. 3 is the structural representation of right positioner.
1 is left positioner in figure, and 2 be right positioner, 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.
Embodiment
A kind of fixture of vacuum pump rotor CNC processing, the left side that described fixture includes being arranged on the left side of vacuum pump rotor 3 are determined
Position device 1 and the right positioner 2 for being arranged on the right side of vacuum pump rotor 3,
Described left positioner 1 makes according to mould and die accuracy, including high-precision pole 4, supporting table 5, described support
For the mounting of the one end of platform 5 in the high-precision front end of pole 4, the other end is imitative type circular bosses 6, and the described imitative edge of type circular bosses 6 is imitative type
Chamfering, the described surface of supporting table 5 symmetrically splice bilateral flat boss 7, set boss to justify on described bilateral flat boss 7
Arc；
Described right positioner 2 makes according to mould and die accuracy, including imitative type boss 8, support round platform 5 and Morse's taper
10, the described imitative surface of type boss 8 sets coarse positioning round platform 11 and fine positioning round platform 12 respectively, and described Morse's taper 10 is fixed
It is arranged on support round platform 9 front end.
During using the utility model, first the boring three-jaw on CNC lathe three-claw chucks, ensures three-jaw clamping center and lathe
Center is concentric, and three-jaw clamps left positioner 1 again, and the MT4 that right positioner 2 is put into the servo tailstock of CNC lathes is pushed up at a high speed
In pin hole, product clamping is carried out, then carries out high-precision turning；To carry out batch high accuracy machining production.
