Abstract

An wire electrode stabilizing apparatus, belongs to the mechanical technology field. Two guiding light rails are fixedly installed on two support blocks; two linear bearings pass through the two guiding light rails; a thread supporting plate hugs the two linear bearings; two springs are passed through the two guiding light rails; the two support blocks are fixed on the left side of the main shaft; the main shaft is connected to a slide plate; the slide plate is connected to a swivel head; the swivel head is connected to a wire electrode; the wire electrode passes through a director guider of the thread supporting plate; an adjusting block is connected to a chute of the thread supporting plate through a connection bolt; an adjusting block can move along the chute; and a connection plate is connected to the bottom of the main shaft. The position of the director guider can be changed with the loss change of the wire electrode based on requirement, therefore the wire electrode can rotate for processing in a more stable way; the bounce is reduced and the processing precision is raised.

Description

The steady silk device of a kind of wire electrode

Technical field

The utility model relates to the steady silk device of a kind of wire electrode, belongs to field of mechanical technique.

Background technology

Existing spark-erosion perforating machine is to utilize the thin metal copper pipe (also referred to as wire electrode) that continuous rotation moves both vertically to make electrode, and workpiece is carried out to pulse spark electric discharge removal metal.Because the metal copper pipe diameter for pulsed discharge is very little, complete wire electrode length is generally at 400mm, 300mm, and in the time that the initial service wear of electrode tube moves down, the part in the middle of clamper and guider is very easy to occur flexural deformation.In the time of machining small, electrode tube needs smooth rotation, and the machining area that electrode tube middle part distortion can cause bottom to contact with workpiece occurs that some are abnormal, and the part namely contacting with workpiece produces circle and beats, and affects positional precision and the aperture precision of aperture.

Summary of the invention

In order to overcome the deficiency of prior art structure, the utility model provides a kind of wire electrode steady silk device.

The utility model solves the technical scheme that its technical problem adopts:

The steady silk device of a kind of wire electrode, fixedly mounts two guiding optical tracks on two back-up blocks, two linear bearings penetrate two guiding optical tracks; Hold up a fishplate bar to embrace two linear bearings, two springs penetrate two guiding optical tracks; Two back-up blocks are fixed on the left side of main shaft; Main shaft connects slide plate, and slide plate connects swivel head, swivel head connecting electrode silk, and wire electrode is through the guider of holding up a fishplate bar; Adjustment block is connected to by connecting bolt on the chute of holding up a fishplate bar, and adjustment block can move along chute; Fishplate bar is connected to the bottom of main shaft.

The beneficial effects of the utility model:

Guider position can be as required, and the variation of following electronic wire loss length changes, thereby make wire electrode rotate more stably processing, and minimizing is beated, and improves machining accuracy.

Detailed description of the invention

Obviously the many modifications and variations that, those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.

Embodiment 1: a kind of Fu Si mechanism of electric spark small hole machine, shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4; Comprise and support fast 2, guiding optical track 3, spring 5, hold up a fishplate bar 8, linear bearing 10, adjustment block 11, guider 12.On two back-up blocks 2, fixedly mount two guiding optical tracks 3, two linear bearings 10 are penetrated to two guiding optical tracks 3.With holding up a fishplate bar 8 to embrace two linear bearings 10, ensure like this linear precision of holding up a fishplate bar 8 to pump.And by two springs 5 penetrate two guiding optical tracks 3 press in its lower section.Assemble and hold up the left side that entirety is fixed on after a part to main shaft 1 by two back-up blocks 2.1 drive the swivel head 6 on slide plate 4 to rotate vertical motion when adding man-hour main shaft, when wire electrode 7 original state, hold up the guider 12 of a fishplate bar 8 be positioned at wire electrode 7 in the middle of swing maximum position, make the machining state of wire electrode 7 held stationaries; In the time that wire electrode 7 losses move down, adjustment block 11 is encountered slide plate 4, and follows slide plate 4 and move down, and sees Fig. 4, the stressed compressive state of spring 5, and guider 12 maintains a certain distance in swivel head 6.In the time that slide plate 4 completion of processing rise, strut and hold up a fishplate bar 8 to reply home position by spring 5.

Embodiment 2: a kind of Fu Si mechanism of electric spark small hole machine, shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4; On two back-up blocks 2, fixedly mount two guiding optical tracks 3, two linear bearings 10 are penetrated to two guiding optical tracks 3.

Hold up a fishplate bar 8 to embrace two linear bearings 10, ensured like this linear precision of holding up a fishplate bar 8 to pump.And by two springs 5 penetrate two guiding optical tracks 3 press in its lower section; Two back-up blocks 2 are fixed on the left side of main shaft 1.

Main shaft 1 connects slide plate 4, and slide plate 4 connects swivel head 6, swivel head 6 connecting electrode silks 7, and wire electrode 7 is through the guider 12 of holding up a fishplate bar 8; Adjustment block 11 is connected to by connecting bolt on the chute of holding up a fishplate bar 8, and adjustment block 11 can move along chute; Fishplate bar 9 is connected to the bottom of main shaft 1;

In the time that wire electrode 7 losses move down, adjustment block 11 is encountered slide plate 4, and follows slide plate 4 and move down, and sees Fig. 4, the stressed compressive state of spring 5, and guider 12 maintains a certain distance in swivel head 6.In the time that slide plate 4 completion of processing rise, strut and hold up a fishplate bar 8 to reply home position by spring 5.
