Abstract
The utility model relates to a wire winding mechanism for electric spark wire cutting machine tools. A two-speed motor arranged on a base can transfer the motion to an intermediate shaft through a synchronous toothed belt wheel, and can drive a wire winding barrel gear and a wire winding barrel to rotate by using one group of duplicate gears arranged on the sliding sleeve of the intermediate shaft; the other group of duplicate gears can rotate a leading screw to rotate through an end part gear. A slide plate can do reciprocating movement along a flat and a concave guide rails on the base by the way the leading screw is screwed with a nut fixed in a nut seat. Thus the rotation and reciprocating movement of the wire winding barrel can be realized. The utility model has the advantages of stable rotation of the wire winding barrel, low noise, uniform wire arrangement, constant wire tensioning and stable wire feeding.
Description
The utility model relates to NC wirecut EDM machine, particularly the curled hair mechanism of electric spark linear cutting machine.
The electric spark linear cutting machine of now having produced, its curled hair tube mechanism is installed in silk tube left side with motor, pass through yielding coupling, directly order about the rotation of silk tube, simultaneously, pass through wire tube shaft, through the two-stage gear reduction, drive is dragged and is pulled screw mandrel rotation, makes the slide plate band the silk tube and does straight reciprocating motion, thereby realize that wire electrode arranges clocklike curled hair, puts silk by certain flight lead.This curled hair mechanism motor oscillating directly passes to the silk tube, the rotation of silk tube and move asynchronous, the shaft coupling rapid wear, wire is not steady, easily fracture of wire.Chinese patent on August 16th, 89 was announced a kind of curled hair mechanism (CN2042766U).Its operation principle is, rack-mounted reversible electric machine, pass through cog belt, drive the rotation of spline screw mandrel, make planker and curled hair tube carry out linear reciprocating motion with the screw mandrel nut engaged, simultaneously, the outer splined shaft of spline screw mandrel adopts cog belt to be connected with the axle of curled hair tube, drives the forward and reverse rotation of curled hair tube.The transitive relation of this mechanism is: motor → cog belt
On) rotation.The moment that this transitive relation, structure itself can cause rotation of curled hair tube and planker to move is asynchronous, adds backlash, factors such as the torsional rigidity of spline screw axis (thin and long units) is lower, aggravated above-mentioned asynchronously, it is inhomogeneous to occur row's flight lead sometimes, fracture of wire phenomenon etc.This mechanism does not have planker limit travel protective device yet.In addition, its ball-screw---splined shaft processing technology and user's maintenance all have great difficulty.
The purpose of this utility model is, provides that a kind of curled hair tube stability of rotation, vibration noise are little, the silk tube rotates with planker and moves synchronously, and it is even to arrange flight lead, is difficult for fracture of wire, and the curled hair tube mechanism of planker limit travel protective device is arranged.
The technical solution of the utility model is, double speed alternating current generator and support are installed on the base, slide plate can move along a flat V plastic-sticking guiding rail on base, screw mandrel is housed in the slide plate, one end of screw mandrel screws with the nut that is fixed on the interior dress of nut seat on the base, the other end of screw mandrel is equipped with gear, is installed in the bottom of a cylinder base.The silk cylinder base is fixed on the slide plate, on the silk cylinder base curled hair tube and curled hair tube gear is housed.Between support and silk cylinder base, jackshaft is housed, the right-hand member of jackshaft is equipped with the synchronous toothed belt wheel, gets in touch by the synchronous toothed belt wheel of synchronous cog belt and motor end.Sliding sleeve also is housed on the jackshaft, and sliding sleeve is equipped with duplicate gear outward, and duplicate gear meshes with curled hair tube gear and screw mandrel end gear respectively.Be equipped with in the sliding sleeve and be absorbed in flat key, jackshaft has a long keyway and is mated, be equipped with duplicate gear sliding sleeve can in ask on the axle and slide.
On nut seat, can be equipped with in order to eliminate the double nut of screw mandrel drive gap.
Transmission process (referring to Fig. 1): double-speed motor (1) is through synchronous toothed belt wheel (2), synchronous cog belt (3), transmit motion to jackshaft (7), driving duplicate gear (9) by the sliding sleeve on the jackshaft rotates, one group drives curled hair tube (12) rotation through gear (11) in the duplicate gear, another group gear (14) drives screw mandrel (15) rotation, again by with fixing feed screw nut's seat (16) inner nut of base (17), slide plate (13) can be moved along a flat V plastic-sticking guiding rail on base.When the forward and reverse rotation of motor, the also forward and reverse thereupon rotation of silk tube, and doing reciprocating linear motion is simultaneously arranged clocklike curled hair or is put silk by certain flight lead thereby obtain wire electrode.This transmission is reduced to:
Motor → cog belt →
Slide plate and curled hair tube move back and forth
The utility model has the advantages that: (1), motor oscillating are absorbed by base and synchronous toothed belt, silk tube stability of rotation; (2) owing to adopted jackshaft, duplicate gear to pass to silk tube and screw mandrel respectively, no longer connect with two pairs of gears or two secondary cog belts and rotate, it is synchronous to have guaranteed that rotation of silk tube and slide plate move.When duplicate gear rotates, the inevitable rotation simultaneously of wire tube shaft end tooth wheel and screw mandrel end tooth wheel, and two pairs of gear clearances cancel out each other, thus the row's of acquisition silk is even, thread tension is constant, and wire is effect stably; (3) be absorbed in flat key owing to having adopted, when slide plate exceeded stroke, key and jackshaft keyway were thrown off, and the machine insurance effect is played in jackshaft idle running.(4) adopt jackshaft, avoided the elongated weakness of screw mandrel spline, improved the torsional rigidity and the processing technology of turning cylinder, be convenient to user's maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that notification number is the transmission schematic diagram of CN2042766U curled hair mechanism;
