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 methods of precise hole organisation of working and manual processing precise hole.
Background technique
The lesser unthreaded hole of diameter dimension (< φ 2) or threaded hole (< M2) structure are applied non-in the components of precision equipment Often extensively, especially same axial workpiece, current this structure are mostly processed on manual precision meter lathe.Existing precision is small Tail stock 56 can be along the axial activity of guide rail 59, the axle center of machine tool chief axis 50 and tail stock 56 as shown in Figure 1: for hole machined scheme It always is to be overlapped, workpiece 51 is clamped on the collet of lathe, rotates with machine tool chief axis 50;Tailstock cone cylinder 55 and handwheel 57 Between connected by leadscrew-nut mechanism, rotate handwheel, tailstock cone cylinder will move left and right along axial direction;One end of collet handle 54 with Drill chuck 53 is rigidly connected, and the other end is the tapered shaft with Morse's taper structure, equally has Mohs cone in tailstock cone cylinder 55 Collet handle 54 is inserted into the taper hole of tail stock cone cylinder 55 by the taper hole of degree with certain axial force, the tapered surface essence of the two Close fit, drill bit 52 (or screw tap), drill chuck 53, collet handle 54, tailstock cone cylinder 55, handwheel 57 these structural members are with regard to rigid at this time Property links together, and drill bit axle center is overlapped with 50 axle center of lathe spindle, rotates clockwise or counterclockwise handwheel, drill bit (or screw tap) It will accordingly along an axial left side or move right.
When processing precise hole, starting lathe spindle motor, workpiece are rotated together with main shaft first, move lathe along guide rail After tailstock to a suitable position, tailstock set lever 58 is placed in locked position, at this time tail stock matrix just and lathe Lathe bed 60 is rigidly connected, and rotates the handwheel on tailstock, and tailstock cone cylinder just will drive drill bit (or screw tap) axially movable, When drill bit and workpiece contact, cutting material is begun to, forms small structure on workpiece.
But prior art has several disadvantages in that
For the needs of chip removal and cooling, when bit bore, generally carries out pecking precession work, i.e., drill bit needs ceaselessly to make directly Line moves back and forth, especially the deeper aperture of working depth, this is just ceaselessly rotated with greater need for operator clockwise and anticlockwise Handwheel, movement range is big, and physical consumption is more, and processing efficiency is low, also more severe to the abrasion of tailstock tool movement mechanism;
Drill bit (or screw tap) diameter dimension of processing precise hole is smaller, and 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 It is all to be completed by rotation hand wheel, and rotation hand wheel indirectly controls the movement of drill bit with fallback action, operator is difficult pair The stress condition of drill bit (or screw tap) carries out real-time perception, may cause if operator's movement range is slightly larger noted earlier Drill bit (or screw tap) fracture, workpiece scraps.
Summary of the invention
Present invention seek to address that the above problem, a kind of precise hole organisation of working and manual processing precise hole are provided Method, it only makees straight reciprocating motion by hand-held drill chuck under the premise of guaranteeing machining accuracy, and labor intensity is low, It is high in machining efficiency;Since hand directly contacts drill chuck, the stress condition of drill bit can be intuitively experienced in real time, and is carried out real-time Adjustment, avoids drill bit (or screw tap) from damaging because stress is excessive, improves product qualification rate, the technical scheme adopted is as follows:
A kind of precise hole organisation of working, comprising: 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 be slidably connected on guide rail, it is characterised in that: further include for clamp the drill chuck of drill bit or screw tap, collet handle, guide sleeve and Tailstock cone cylinder, the drill chuck and collet handle Joint, the guide sleeve left part have cylindrical pilot hole, and right part is with not The bullet of family name's taper;The collet handle be threaded onto pilot hole and with pilot hole clearance fit, the tailstock cone cylinder have not The bellmouth of family name's taper, the bullet and tailstock cone cylinder Morse's taper of the guide sleeve cooperate, and the handwheel passes through feed screw nut machine Structure drives axial direction of the tailstock cone cylinder in tail stock along bullet to move to the left or to the right.
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 suitable position along guide rail and is locked by tailstock set lever Tightly, the bullet of guide sleeve is inserted into tailstock cone cylinder and is fitted close with certain axial force;Then collet handle is inserted into In the pilot hole of guide sleeve, clearance fit between collet handle and the pilot hole of guide sleeve, drill chuck is positioned by pilot hole, both can edge Pilot hole axial free movement, and can guarantee that axis is overlapped always with the axis of lathe spindle when being axially moved, processing precise When aperture, it is only necessary to which handheld drill collet axial direction straight line, which moves left and right, can be completed drilling or tapping.
The present invention has the advantage that only making linear reciprocation by hand-held drill chuck under the premise of guaranteeing machining accuracy Movement, labor intensity is low, high in machining efficiency;Since hand directly contacts drill chuck, drill bit can be intuitively experienced in real time Stress condition, and adjusted in real time, drill bit (or screw tap) avoided to damage because stress is excessive, improve product qualification rate.
