Conical bore boring machine has drill unit.
Among the present invention, conventional mechanism, systems such as lathe bed, electrical control driving mechanism, workpiece detent mechanism, digital control system, slide unit, main motor mechanism, main spindle box are all identical with machine tool.Knife bar, cutter head and directly related with it part are formed the reducing boring head, are core of the present invention, it and slide unit, driving mechanism, digital control system, composition reducing boring unit head.Drill unit is common borehole drill construction, and operated by rotary motion is at the offside with respect to reducing boring unit head, i.e. the another side of workpiece detent mechanism.
When the present invention works, at first workpiece is bored bottom outlet by drill unit, and then by reducing boring unit head boring taper hole.During heavy boring, slide unit drives main shaft and walks to small end from the big end of workpiece taper hole, and during right boring, slide unit drives main shaft and walks to big end from the small end of workpiece taper hole, and radially machining direction remains unchanged always.During boring, set the parameter of numerical control device, servo motor B is just being changeed driving slide unit drive boring head and is being moved forward vertically, promptly move to workpiece, servomotor A is just changeing and promotes the relative main shaft of push rod by screw body and move forward vertically, promote ramp blocks, pass through radial ball bearing, pushing block makes slide block move radially along dovetail slideway, driving knife bar radially moves, heavy boring cutter on knife bar arrives the workpiece bore position, it is taper hole straight edge line heavy boring starting point, numerical control device is by setting value control servomotor A, B is by certain mathematical relationship work, knife bar is in that axially and radially the motion of two directions is synthetic, realize the linear reducing of variable cross-section, make the heavy boring cutter walk out the straight edge line of conical bore, main shaft just changes under main motor mechanism drives simultaneously, drive knife bar and heavy boring cutter and make cutting movement, carry out the roughing of conical bore, heavy boring finishes, and the heavy boring cutter is walked from workpiece, and fine boring cutter arrives taper hole straight edge line right boring starting point, the counter-rotating of cnc mechanism control servo motor B, slide unit drives main spindle box, main shaft returns, and servomotor A keeps former setting just to change, the synthetic linear reducing of variable cross-section of realizing of two motions, make fine boring cutter walk out the straight edge line of conical bore, then carry out the fine finishining of conical bore, right boring finishes, and fine boring cutter is walked from workpiece, numerical control device control servomotor A, B all reverses, main motor mechanism stall makes knife bar get back to initial point, finishes the processing of a conical bore.
Among the present invention, the tool path pattern of boring unit head and driving mechanism are that the principle according to the linear reducing of variable cross-section manufactures and designs, it meets the geometrical property of cone fully and forms mechanism, be the linear reducing boring of a variable cross-section truly unit head, therefore can boring process the circular section conical bore of standard.Simultaneously, symmetry is installed thick, smart two boring cutters on the knife bar, adopts the reciprocation type feed, is not prolonging the feed stroke, is not increasing under the prerequisite of boring cutter bar length, can realize thick smart two work steps processing; When heavy boring and right boring, push rod is to push away forward always, knife bar to move radially direction constant, error very close to each other; It is constant that linear in addition reducing can make boring cutter intrinsic operating angle maintenance in process stablize, and this all will improve the machining accuracy in hole greatly.
The Precision Machining conical bore will be through drill-over bottom outlet, heavy boring conical bore, right boring conical bore three road manufacturing procedures.Be provided with drill unit among the present invention, three road manufacturing procedures of conical bore processing can all be finished on a boring machine.
Empirical tests with technical indicators such as its taper hole that bores, its surface smoothness, tapering, bus nonstraightness, small end apertures, is controlled within the specification requirement of detail drawing fully, and reliable and stable.
Owing to adopted linear reducing technology of variable cross-section and double-pole to come and go the linear reducing boring of feed art designs variable cross-section unit head, and and the Numeric Control Technology combination, make the present invention have characteristics such as compact conformation, machining accuracy height, automaticity height, and tapering can freely be provided with, applicability is strong, the work noiselessness, long service life.
