The method of adjusting workpiece angle is to be placed on workpiece with angular surveying piece, with being adsorbed on dial gauge on lathe, checks whether level of angle comparison block measurement datum.The accuracy that guarantees frock adjusting angle by precision and the machine tool accuracy of angular surveying piece.
Preferably, when the workpiece of required processing is longer, need to match by longer workpiece mounting plate, can select many group frock supporting stations and revolving body with supporting workpiece installing plate; In a preference of the present utility model, used two groups of frock supporting stations and revolving body with supporting workpiece installing plate.
Preferably, revolving body adopts and is threaded with frock supporting station, in a preference of the present utility model, used T-shaped screw bolt and nut to connect, unclamped nut, revolving body and workpiece mounting plate can have been rotated on frock supporting station, thereby regulate the angle of workpiece and lathe table top, also just adjusted the angle of workpiece and cutter, after having adjusted, locking nut.
Preferably, the clamp mechanism on workpiece mounting plate comprises screw corresponding on pressing plate, brace table and screw and workpiece mounting plate.
Preferably, in order to expand the angle of regulation range of frock, can also under frock base plate, increase auxiliary adjustment piece, described auxiliary adjustment piece is triangular prism shaped, frock base plate can be raised to milling machine mesa shape angled, from the angle of practical application, the numerical value that auxiliary adjustment piece is raised the angle of frock base plate and milling machine table top is advisable between 0-45 °.
The utility model has the advantage of:
The turbine blade oblique surface machining frock that the utility model provides is used in the processing of carrying out turbine blade inclined-plane on horizontal milling machine, and angle wherein can regulate arbitrarily, and guarantees that precision is reliable, and processing is stable; The scope of application is extensive, for the inclined-plane within the scope of 0-90 °, can process.
After the turbine blade oblique surface machining frock angular adjustment that the utility model provides, use angle is measured the position that comparison block guarantees converted products and machine tool, thereby raising Product Precision, by manufacturing the angular surveying comparison block of degree of precision, make the accuracy of manufacture of frock can be relatively low, do not affect product quality.
Between the turbine blade oblique surface machining frock supporting base that the utility model provides and revolving body, for the face of cylinder coordinates, the shape on the face of cylinder is convenient to the making of frock, is also convenient to adjusting tool angle.
