Detailed description of the invention
Existing engine lathe itself has the function of bore hole, and the present invention changes a social system engine lathe, can complete taper deep hole boring.The transformation of the way or the part increased comprise boring bar 7, boring cutter 10, Double-conical-surface core bar 9, cylinder core bar 28, screw thread spline core bar 27 etc.Scroll chuck 3 in Lathe Spindle Box 4, clamped by the workpiece 2 with taper deep hole, centre frame 33 is by the other end holding workpiece.
Oil delivering unit support 30 is fixed in a certain position of lathe bed 1 guide rail according to the length of workpiece, oil delivering unit support 30 is fixed with oil delivering unit seat 29, and one end of revolving meber 32 is arranged on oil delivering unit seat 29 by bearing, and the other end contacts with workpiece end face.
One end of boring bar 7 is fixedly connected with slide carriage 26, and boring bar 7 makes axial feed with slide carriage 26 along the movement of bed ways, and servomotor 25 and the shaft coupling 24 be attached thereto, spline housing 23 also move thereupon.The power resources of slide carriage motion are main motor.
Two radial direction through hole processed by the wall of oil delivering unit seat 29, enters fluid from macropore, fluid, by the inner space of oil delivering unit seat 29, the inner space of revolving meber 32, flows to boring cutter place, washes away iron filings, cooling, lubrication working position.Iron filings, fluid are from other one section of outflow of workpiece.Scroll chuck place is provided with scroll chuck cover 37, when spindle hole is by artificial shutoff in advance, iron filings, fluid are under the influence of centrifugal force, be thrown to from the space between claw in scroll chuck cover, prevent fluid from throwing away, produce and pollute, the bottom of scroll chuck cover is provided with chip removal mouth, adopt prior art to be cleared up by iron filings in time, prevent iron filings from piling up.
Enter other high-voltage oil liquid from the little radial direction through hole oil delivering unit seat 29 wall, by the axially extending bore pushing revolving meber 32 on oil delivering unit seat 29 wall, prevent its axial play.
Be provided with in the transverse holes of boring bar 7 and relative to the boring cutter 10 of boring bar movement, Double-conical-surface core bar 9, cylinder core bar 28, screw thread spline core bar 27 can be placed with in the axial hole at boring bar center, boring bar be provided with swivel nut 12, spring 16, support bar 14.
Boring cutter 10 has taper hole, the taper hole that the anterior conical surface of Double-conical-surface core bar 9 is offered through boring cutter, and with one side contacts, opposite side does not contact, i.e. shifted relative.Due to the tensioning function of extension spring 40 pairs of boring cutters, single edge contact remains.When servomotor 25 rotates, when driving screw thread spline core bar 27 to rotate by shaft coupling 24 and spline housing 23, screw thread spline core bar 27 and the cylinder core bar 28 be attached thereto, Double-conical-surface core bar 9 move axially relative to boring bar 7, by the effect of Double-conical-surface core bar 9 inner cone, make boring cutter radial motion, process taper hole.
The rear portion conical surface of Double-conical-surface core bar 9 and the end thereof contacts of support bar 14, other one end of support bar contacts with workpiece 2, and support bar 14, through the hole in the middle part of the swivel nut 12 being fixed on boring bar, can move relative to swivel nut.Support bar 14 one end with annular protrusion, mounting spring 16 between annular protrusion and swivel nut, one end that spring 16 makes support bar 14 all the time with the taper-face contact of Double-conical-surface core bar 9, when 9 axially-movable of Double-conical-surface core bar, make support bar 14 radial motion.When the hole of institute's boring diminishes, because Double-conical-surface core bar 9 two conical degree of conical surfaces are identical, support bar 14 inwardly moves, and adapts with processed hole.The existence of support bar, serves the effect of supplemental support, can reduce the distortion of boring bar, and this is very dark for hole, and cone hole machine when boring bar is longer, acts on very large.
The two ends band of support bar 14 is gradient, the one end contacted with Double-conical-surface core bar 9, and gradient is consistent with the core bar conical surface, and with one end of absorption surface, gradient is consistent with workpiece tapering.
Support bar is processed with keyway, and dismountable stop pin 13 snaps in keyway; Prevent support bar 14 from turning round around own axes.Float support has two, one of them float support axis and boring cutter axis being parallel or close to level, and the offside of boring cutter point of a knife is positioned at relative to boring bar axis, radial cutting force is born in help, another one float support axis and boring cutter axial space interlock, and vertical or close vertical, are positioned at below boring cutter, cutting force is born in help, reduces the distortion of boring bar.
Boring cutter 10 is provided with long spiro nail 39, long spiro nail 39 is positioned at the gathering sill that boring bar 7 is offered, be connected with the short screw 38 be fixed on boring bar 7 by extension spring 40, the pulling force by spring makes the conical surface of the taper hole of boring cutter 10 and Double-conical-surface core bar 9 remain single edge contact.
Double-conical-surface core bar 9 and cylinder core bar 28, screw thread spline core bar 27 is coaxial, the right-hand member of Double-conical-surface core bar 9 is porose, hole and cylinder core bar 28 left end minor diameter position match, a pin is had to be horizontally through both matching parts, the right-hand member of cylinder core bar 28 is porose, match with screw thread spline core bar 27 left end smaller diameter end in hole, a pin is had to be horizontally through both matching parts, on screw thread spline core bar 27, threaded portion matches with the screw thread in boring bar right-hand member hole, splined section on screw thread spline core bar 27 matches with spline housing 23, splined section and contiguous position thereof have spatially with many graduation marks of core bar axis serrated vertical, spline housing is connected with servomotor 25 by shaft coupling 24.Many graduation marks can help to understand and check screw thread spline core bar 27 to move axially distance, help thus understand and check the boring cutter radial motion distance be attached thereto, and namely help understand and check taper hole aperture.
Industrial endoscope 34 is installed in hole that boring bar 7 is offered.Lens location design is advisable with the working angles observing point of a knife place, but leaves point of a knife certain distance, the transparent sealing lid 35 installed before preventing iron filings from damaging camera lens.
Two conical degree of conical surfaces of Double-conical-surface core bar 9 are equal.
Swivel nut 12 is fixed on boring bar, and support bar 14, through the hole at swivel nut center, swivel nut end face is processed with two holes, for tightening or unclamping swivel nut.
System many places arrange seal, to prevent oil liquid leakage.Swivel nut another one end face and swivel nut centre bore hole wall are processed with cannelure, place blind nut seal 17, float support seal 15 in groove respectively, prevent oil liquid leakage.Be processed with cannelure respectively in the both sides of boring cutter 10 bellmouth, place seal 11 in groove, Leakage prevention.One end of boring bar 7 is provided with boring bar end cap 6, and boring bar end cap 6 end face offers cannelure, places seal 8 in groove.Prevent draining.At cylinder core bar 28 cylindrical and boring bar 7 endoporus contact position, O-ring seals is installed.
Servomotor 25 is connected with impulse generator 36 by numerical control control device 31, and impulse generator is connected with lathe spindle 5.Lathe spindle each transfer n pulse, reach the control device 31 of be equipped with digital control system through electric wire, according to the instruction of program, make control device 31 export required pulse, allow servomotor 25 do the gyration of required speed.Make boring cutter to coordinate mutually along workpiece radial motion with boring cutter along moving of axis of workpiece direction like this, ensure that the tapering processed meets the requirements.
