Description

3rd Zhou Zu mechanism and with its composition walk core type turn-milling machine tool
Technical field
The present invention relates to the 3rd Zhou Zu mechanism and with its composition walk core type turn-milling machine tool.
Background technology
Existing walk on scheming market, this technology of kinematic axis for lathe possesses some special knowledge always, and what be instantly most widely used is exactly that three axles comprising the positive axis axle group be made up of X1 axle group, Y1 axle group, Z1 axle group walk core type turn-milling machine tool; Or, when the increase of countershaft structure has Z2 axle group, then coordinate positive axle construction row to become four axles to walk core type turn-milling machine tool; Or the positive axle construction of countershaft respective outer side edges be made up of X2 axle group, Z2 axle group when countershaft forms five axles and walks core type turn-milling machine tool; Or the positive axle construction of countershaft respective outer side edges be made up of X2 axle group, Z2 axle group, Y2 axle group when countershaft forms six axles and walks core type turn-milling machine tool.
Above-mentioned existing walk the positive axle construction X1 axle group of core type turn-milling machine tool, Y1 axle group, Z1 axle group three parts, wherein the positive main shaft of lathe is arranged on Z1 axle slide plate, be through hole in the positive main shaft of lathe, workpiece raw material are directly sent in the positive main shaft of lathe, for convenience of processing, the positive main shaft tail end of lathe connects feeder, feeder is sustainable uninterrupted to the positive main shaft feeding of lathe, machine tool chief axis holding workpiece material, material is driven to move back and forth in Z-direction, after workman edits program, main shaft coordinate lathe guide sleeve structure (guide pin bushing can with synchronous electric guide pin bushing, the exchanges such as interlock guide pin bushing) or without guide sleeve structure, workpiece is delivered to close to cutter, cutter follow procedure sequencing carries out first aft-loaded airfoil to the different operations of workpiece respectively.Complete turning, milling, boring, tapping that workpiece can complete in positive axle construction respectively, the operation such as eccentric orfice is shaping, inclined hole is shaping.After positive axis structural constraint cuts off workpiece, as cutting workpiece end face needs reprocessing, then main axle structure cannot realize, and needs the error that increase countershaft structure is brought because of secondary clamping to avoid workpiece.Countershaft axle group and the positive axle construction of lathe are installed in opposite directions, be positioned at the countershaft position of lathe, countershaft structure is become by X2 axle group, Y2 axle group, Z2 axial fabric, or be made up of X2 axle group, Z2 axle group, or be made up of Z2 axle group, during mainly for work pieces process, the cut-out end face processing that positive axle construction cannot complete.Auxiliary main shaft of machine tool is arranged on the slide plate of Z2 axle group, coordinate the positive spindle processing of lathe, scoop out the workpiece spread out of by the positive main shaft of lathe, after workpiece is cut-off, auxiliary main shaft of machine tool holding workpiece, coordinates blade row, processes the back side of workpiece, also positive axis can be replaced to complete part processing, save process time.The techniques such as when after Workpiece shaping, the part processed can be sent by auxiliary main shaft of machine tool automatically, and this countershaft structure can complete accessory turning, milling, boring, tapping, engraving equally, inclined hole is shaping, eccentric orfice is shaping.According to the processing arrangement of workpiece to be processed, can determine whether to need to increase countershaft structure, or increase Z2 axle group in countershaft separately, form four axles with positive axle construction and walk core type turn-milling machine tool; Or Z2 axle group and X2 axle group, form five axles with positive axle construction and walk core type turn-milling machine tool in increase countershaft; Or the Z2 axle group in increase countershaft, X2 axle group, Y2 axle group, form six axles with positive axle construction and walk core type turn-milling machine tool.
Cutting tool installation manner plate in positive axle construction can install two row's cutters, two row's cutters exist in the X direction in opposite directions, because Cutting tool installation manner plate is a complete part, therefore all cutters are synchronization action when X, Y, Z tripartite moves upward, and the technique of required processing can only could be carried out the processing of next technique after a cutter completes stroke by next cutter.This just causes lathe lathe positive axis when processing work to have drawback, and cutter mutually limits to and causes the Workpiece shaping time well not optimized, and affects the shaping efficiency of workpiece.
