The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
For a boring machine fixture for boring taper hole, as shown in Figure 1, comprising: support set 1, positioning sleeve 2, lubricating cup 3, platen 4, copper sheathing 5, main axis arbor 6, lathe tool 7, cutter holder 8, taper liner 9, mandrel 10, nut 11, steel ball 12, nut 13 and bearing pin 14; Wherein, positioning sleeve 2 is connected with support set 1, and gland 4 is connected with positioning sleeve 2, and mandrel 10 is connected with main axis arbor 6; Bearing pin 14 two ends are also with fine thread button, it is through the slotted hole groove of main axis arbor 6, through hole through mandrel 10 right-hand members, is connected with mandrel 10 with main axis arbor 6 respectively, and nut 13 is connected with bearing pin 14, steel ball 12 is between nut 13 and bearing pin 14, the gradient of taper liner 9 is identical with the gradient of mandrel 10 ramps, and cutter holder 8 one end have endoporus one end to have outer button, and clamping is in the inclined-plane of taper liner 9 and mandrel 10 track elongated slot, lathe tool 7 is contained in the endoporus of one end, and nut 11 is tightened on the screw thread of one end.
For a boring machine fixture for boring taper hole, as shown in Figure 1, wherein the material of taper liner 9 is brass.
As shown in Figure 1, support set 1 works to support a whole set of frock, long slot bore width on main axis arbor must coordinate with pin diameter appropriately, long slot bore length is to determine according to the length of long slot bore on mandrel 10 left end surface rails, positioning sleeve 2 via nitrides are arranged on support set 1 after processing, the parts such as copper sheathing 5, bearing pin 14 are played the role of positioning, and gland 4 also via nitride is arranged on positioning sleeve 2 after processing, and works to stop that bearing pin 14 seesaws, two copper sheathings 5 are tight fits with coordinating of positioning sleeve 2, gland 4, and copper sheathing 5 is supporting main axis arbor 6, and the rotation meeting of main axis arbor causes wearing and tearing and can not cause wearing and tearing to main axis arbor copper sheathing, after copper sheathing wearing and tearing, can change easily, mandrel 10 is critical components of this cover frock, be arranged in the hole of main axis arbor 6, the through-hole diameter of mandrel 10 right-hand members also must coordinate with pin diameter appropriately, mandrel left end is surface rail, the gradient of this surface rail and long slot bore length can design according to the actual tapering on workpiece, bearing pin 14 will carry out modifier treatment and be key component, two ends are also with fine thread button, it is through the slotted hole groove of main axis arbor 6, through hole through mandrel 10 right-hand members, during work, between bearing pin 14 and positioning sleeve 2 and gland 4, produce friction, after being used wearing and tearing, bearing pin 14 can change, two nuts 13 are tightened in respectively on the screw thread at bearing pin 14 two ends, its effect is just the same with the retainer effect in bearing, as shown in Figure 2, guarantee that steel ball 12 can rotate freely and can not be dropped out in nut 13, steel ball 12 plays flexible rotating, and can be by lubricating cup 3 to positioning sleeve 2 the inside note butter, to steel ball 12, the flexible rotating of bearing pin 14 plays lubrication, the gradient of two taper liners 9 is identical with the gradient of mandrel 10 ramps, the material of taper liner is brass, after the inclined-plane orbital motion wearing and tearing on mandrel 10, can change easily, cutter holder 8 one end have endoporus one end to have outer button, and clamping is in the inclined-plane of two taper liners 9 and mandrel 10 track elongated slot, and lathe tool 7 is contained in the endoporus of one end, and two nuts 11 are tightened on the screw thread of one end, after the two nut back ofs the body are tight, can adjust the gap between two taper liners 9 and inclined-plane track, cutter holder 8 and taper liner 9 can be slided freely flexibly on the inclined-plane of mandrel 10 track.
After frock of the present invention assembles, be arranged on the facing head of TPX6113 boring machine, main axis arbor 6 packs in inner hole of spindle, allows the facing head of boring machine maintain static during use, only allows main shaft rotate and stretches two motions; Flexible promotion main axis arbor 6 and the cutter holder 8 of main shaft seesaw, and seesawing of cutter holder 8 is that surface rail along mandrel 10 left ends seesaws, and the proal while of cutter holder 8 also can move downward along surface rail; Rotatablely moving of main shaft also can drive main axis arbor 6, cutter holder 8 and bearing pin 14 to rotate simultaneously; Due to bearing pin 14 be glanded 4 and positioning sleeve 2 limited the action seesawing, so bearing pin 14 can not seesaw, can only rotate and be with moving mandrel 10 to rotate simultaneously, mandrel 10 also just can not seesaw; Cutter holder 8 drives lathe tool 7 motions, and the motion of cutter holder 8 is exactly the motion of lathe tool 7; Lathe tool 7 has three motions simultaneously: seesaw, move up and down, rotatablely move, the biosynthesis locus of these three motions has just formed the process of a cutting internal conical surface; Internal taper hole from large end boring to small end; Only needing to regain fast main shaft just can rapid return; Very easy to use flexible; The facing head that uses this frock boring machine is fixed, only needs the flexible of main shaft and two kinds of motions of rotation just can complete the processing of internal conical surface, is highly suitable for that facing head and main shaft can only rotate respectively and the boring machine that can not simultaneously rotate.
The present invention does not describe part in detail, is those skilled in the art of the present technique's known technology.
