Description
Technical field
The utility model relates to a kind of machining tool fixture, more specifically to a kind of Boring in-step frock clamp.
Background technology
In Francis turbine, water distributor is made up of protecgulum, bonnet, stator etc., and stator is contained in the middle of front and rear covers.In unit design, require that protecgulum, bonnet must with one heart, guarantee stator flexible rotating, is not stuck.In the prior art, be not exclusively used in Francis turbine front and rear covers Boring in-step frock clamp, realize front and rear covers Boring in-step must carry out in large-scale, high precision apparatus, and therefore investment is large, and versatility is little.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides the Francis turbine front and rear covers Boring in-step frock clamp that a kind of structure is simple, small investment, versatility are good.
The purpose of this utility model is achieved by following technical scheme: a kind of Francis turbine front and rear covers Boring in-step frock clamp, comprise calibration flange and front and rear covers Special connection seat, uniform installation calibration block on calibration flange, calibration block number is equal with the hole number that front and rear covers need be processed, calibration flange inner diameter and front and rear covers external diameter match, calibration flange outer diameter and vertical lathe workbench size match, calibration flange is provided with clamping hole (clamping hole play with bolt through clamping hole thus calibration flange is fixedly installed in the effect of vertical lathe workbench), calibration flange is arranged on vertical lathe workbench, front and rear covers Special connection seat seam size and front and rear covers external diameter match, front and rear covers Special connection seat is provided with front and rear covers connecting hole (front and rear covers connecting hole play with bolt through front and rear covers connecting hole thus connect front and rear covers effect), protecgulum, bonnet are linked as a clamp body by front and rear covers Special connection seat, and clamp body to be arranged on vertical lathe workbench and to be positioned at calibration flange.
The utility model processing method is as follows:
1, first in the middle of vertical lathe workbench, load onto vertical car jaw, pass the clamping hole on calibration flange thus be arranged on vertical lathe workbench by the uniform calibration flange being provided with calibration block with bolt, vertical car jaw is positioned at calibration flange;
2, protecgulum is first put on vertical lathe workbench, protecgulum is fixed with vertical car jaw, put front and rear covers Special connection seat above protecgulum, bonnet is placed on above front and rear covers Special connection seat, passes front and rear covers connecting hole thus protecgulum, bonnet and front and rear covers Special connection seat are linked as a clamp body with bolt;
3, rotate vertical lathe workbench, when reference block aims at calibration block, after correcting protecgulum plane and inner circle with vertical lathe workbench knife rest, lock workbench, with the boring head bore hole on vertical lathe workbench knife rest to drawing dimensional requirement.
This frock clamp is simple to operate, and machining accuracy is high, and working (machining) efficiency is high, utilizes traditional machining process, achieves the accurate processing of hydraulic turbine front and rear covers with boring, reduces the input of large-sized numerical control equipment.
