Description

A kind of method of precise hole organisation of working and manual processing precise hole
Technical field
The present invention relates to a kind of method of precise hole organisation of working and manual processing precise hole.
Background technology
The less unthreaded hole of diameter dimension (<φ 2) or screwed hole (<M2) structure is applied non-in the parts of precision equipment Often extensively, especially same axial workpiece, current this structure is more to be processed on manual precision meter lathe.Existing precision is small Hole machined scheme is as shown in Figure 1:Tail stock 56 can be along the axially activity of guide rail 59, the axle center of machine tool chief axis 50 and tail stock 56 All the time it is to overlap, workpiece 51 is clamped on the chuck of lathe, rotated with machine tool chief axis 50;Tailstock cone cylinder 55 and handwheel 57 Between connected by screw-nut body, rotate handwheel, tailstock cone cylinder will move left and right vertically;One end of chuck handle 54 with Drill chuck 53 is rigidly connected, and the other end is equally to have Mohs cone in the tapered shaft with Morse's taper structure, tailstock cone cylinder 55 In the taper hole of degree, the taper hole that chuck handle 54 is inserted into tail stock cone cylinder 55 with certain axial force, the taper surface essence of the two Close fit, now drill bit 52 (or screw tap), drill chuck 53, chuck handle 54, tailstock cone cylinder 55, these structural members of handwheel 57 are just firm Property link together, drill bit axle center and the axis coinciding of lathe spindle 50 rotate clockwise or counterclockwise handwheel, drill bit (or screw tap) Will be accordingly left vertically or move right.
During processing precise hole, start lathe spindle motor first, workpiece is rotated with main shaft, and lathe is moved along guide rail Behind tailstock to a suitable position, tailstock set lever 58 is placed in locked position, now tail stock matrix just and lathe Lathe bed 60 is rigidly connected, and rotates the handwheel on tailstock, and tailstock cone cylinder will drive drill bit (or screw tap) axially movable, When drill bit is contacted with workpiece, begin to cut material, small structure is formed on workpiece.
But prior art has following shortcoming:
General progress is pecked the need for for chip removal and cooling, during bit bore needs ceaselessly to make straight into action, i.e. drill bit Line is moved back and forth, especially the deeper aperture of working depth, and this is just ceaselessly rotated clockwise and anticlockwise with greater need for operator Handwheel, movement range is big, and physical consumption is more, and processing efficiency is low, and the abrasion to tailstock tool motion is also more severe;
Drill bit (or screw tap) diameter dimension of processing precise hole is smaller, and its mechanical strength is very weak, stress in process Drill bit (screw tap) fracture and workpiece may be caused to scrap if slightly larger, delay normal production;In existing scheme drill bit peck into All completed with fallback action by rotation hand wheel, and the action of rotation hand wheel indirect control drill bit, operator is difficult pair The stressing conditions of drill bit (or screw tap) carry out real-time perception, may be caused if operator's movement range is slightly larger noted earlier Drill bit (or screw tap) fracture, workpiece scraps.
The content of the invention
Present invention seek to address that there is provided a kind of precise hole organisation of working and manual processing precise hole for above mentioned problem Method, it only makees straight reciprocating motion, labor intensity is low on the premise of machining accuracy is ensured by hand-held drill chuck, It is high in machining efficiency;Because hand directly contacts drill chuck, the stressing conditions of drill bit can be intuitively experienced in real time, and carry out real-time Adjustment, it is to avoid drill bit (or screw tap) improves product qualification rate because stress is excessive and damages, and the technical scheme that it is used is as follows:
A kind of precise hole organisation of working, including:Lathe bed, the lathe spindle with Workpiece clamping head, tail stock, handwheel, Guide rail and for locking, discharge the tailstock set lever of tail stock, the guide rail is fixedly installed on lathe bed, the lathe tail Seat is slidably connected on guide rail, it is characterised in that:The drill chuck that also includes being used for clamping drill bit or screw tap, chuck handle, guide pin bushing and Tailstock cone cylinder, the drill chuck and chuck handle Joint, the guide pin bushing left part have cylindrical pilot hole, and its right part is with not The bullet of family name's taper;The chuck handle is threaded onto in pilot hole and coordinated with being oriented to interporal lacuna, and the tailstock cone cylinder has not The bellmouth of family name's taper, bullet and the tailstock cone cylinder Morse's taper of the guide pin bushing coordinate, and the handwheel passes through feed screw nut machine Structure driving tailstock cone cylinder is moved to the left or to the right in tail stock along the axial direction of bullet.
A kind of method of manual processing precise hole:Workpiece is clamped first with the Workpiece clamping head of lathe spindle, in drill point Drill bit or screw tap are clamped on head as needed, tail stock is moved to correct position along guide rail and locked by tailstock set lever Tightly, the bullet of guide pin bushing is inserted into tailstock cone cylinder and is fitted close with certain axial force;Then chuck handle is inserted into In the pilot hole of guide pin bushing, gap coordinates between chuck handle and the pilot hole of guide pin bushing, and drill chuck is positioned by pilot hole, both can edge Pilot hole axial free movement, can guarantee that axis is overlapped all the time with the axis of lathe spindle when being axially moved, processing precise again During aperture, it is only necessary to which handheld drill chuck axial direction straight line, which is moved left and right, can complete drilling or tapping.
The invention has the advantages that:On the premise of machining accuracy is ensured, linear reciprocation is only made by hand-held drill chuck Motion, labor intensity is low, high in machining efficiency;Because hand directly contacts drill chuck, drill bit can be intuitively experienced in real time Stressing conditions, and adjusted in real time, it is to avoid drill bit (or screw tap) improves product qualification rate because stress is excessive and damages.
