Summary of the invention
The object of the present invention is to provide a kind of random working angle precision electrolytic machining method and lathe, the gas that produces in the electrolytic process during with solution micro hole Electrolyzed Processing and the timely discharge problem of other electrolysates.
A kind of random working angle precision electrolytic machining method, utilize angular adjustment apparatus make machine tool chief axis obtain vertical, horizontal or between vertical and horizontal between arbitrarily angled processing posture, comprehensively solve in electrolysate and the electrolysis gas and discharge problem.
A kind of random working angle precision electrolytic machine tool, comprise lathe base, lathe bed, be installed on workbench, the work box formed by X workbench, Y workbench and Z workbench on the lathe bed, the electric main shaft that has electricity-leading device, it is characterized in that: between described lathe bed and the lathe base angular adjustment apparatus is housed.
Above-mentioned angular adjustment apparatus is installed on the adjustment handle on screw mandrel top by the slide block, guideway, the leading screw that are installed on the base, and the lathe bed pole that connects above-mentioned slide block and lathe bed is formed.
Electricity-leading device on the above-mentioned electric main shaft by insulated electro brush holder, electrode, draw that electric axis is held, attachment screw, draw electric screw and form, the axle external part interference fit of conductive bearing inner ring and electric main shaft wherein, the insulated electro brush holder by radially draw electric screw, and axial attachment screw be fixed on the outer ring of conductive bearing.
Above-mentioned accurate electrolytic machine tool, electric range of spindle speeds cover from 0 rev/min～100000 rev/mins, ac variable frequency speed regulation.
Characteristics of the present invention be by utilize angular adjustment apparatus make machine tool chief axis obtain vertical, horizontal or between vertical and horizontal between arbitrarily angled processing posture.When the big micropore of processing aspect ratio, when tool-electrode was in vertical position, especially when the micro hole Electrolyzed Processing, electrolysate was difficult to timely eliminating, caused processing unstable even can't process.When the horizontal layout of tool-electrode, help the discharge of electrolysate and upgrading in time of electrolyte this moment, but the gas that produces in the electrolytic process is difficult to timely discharge.When the micropore of some specific type of processing, need take all factors into consideration in electrolyte renewal and electrolysate and the electrolysis gas and discharge problem, and between vertical and horizontal between arbitrarily angled adjustable precision micro-electrochemical machining lathe can find satisfactory processing posture.Also there is not this fine electrolytic machining tool structure at present both at home and abroad.Because tool-electrode is installed on the main shaft in the accurate Electrolyzed Processing, the main shaft of rotation has brought electric problem of drawing of rotary tool electrode at a high speed, electricity-leading device among the present invention comprises conductive bearing, draw electric screw, hold-down screw, insulation sleeve is formed, on the conductive bearing outer ring, apply suitable radial load by hold-down screw, action of centrifugal force when reducing to rotate at a high speed increases contact area, has guaranteed to draw electric reliability.In addition, platen adopts the accurate displacement workbench, the precision height, and resetting is accurate, adopts four-axle linked motion control card to carry out motion control.Since machine adopted precision parts and good configuration design, thereby realized the requirement of lathe high accuracy processing.
Module design of the present invention, miniaturization, the workbench of employing outsourcing, the lathe overall weight is light, and volume is little, can carry out angle adjustment, has good operating space, and can the electric machining three-dimensional microstructures.
