Description

The rocker frame mechanism of wire cutting machine tool taper head

Technical field

The present invention relates to a kind of rocker frame mechanisms for wire cutting machine tool taper head.

Background technology

Currently used for the rocker frame mechanism of Wire cut electric discharge machine rate taper head, mostly driven in U axis and V axis by cross saddle It is moved on direction, to realize taper WEDM；Existing rocker frame mechanism, including upper balance staff, lower balance staff, the branch connected firmly with upper balance staff The front end of seat, the support base being placed on lower balance staff, upper balance staff and lower balance staff is equipped with leading wheel seat, and upper balance staff passes through with lower balance staff Two level articulated mounting is connected；Not only above the connection structure of balance staff and lower balance staff is complex for the device, installs, is inconvenient for use, and When U axis directions move, articulated mounting can be servo-actuated upper balance staff, hinge joint generates rotation, wear larger, generation processing for a long time Error influences processing quality；And in upper balance staff when doing the movement of U axis directions, due to need to come by the swing of two level articulated mounting It completes, is limited by swing angle, cause its axial stroke less than normal, it is difficult to complete steep-taper processing, such as to increase its axial row The size of journey, two level articulated mounting must be larger, so causes again using limited.

Invention content

The purpose of the present invention is being directed to deficiencies of the prior art, a kind of pendulum of wire cutting machine tool taper head is provided Frame mechanism, it has the advantages that structure is relatively easy, installs, is easy to use, and wears small, it is ensured that processing quality and realization are big Taper WEDM.

In order to achieve the above objectives, the rocker frame mechanism of wire cutting machine tool taper head of the invention, including upper balance staff, lower balance staff, The front end of the bearing connected firmly with upper balance staff, the support base being placed on lower balance staff, upper balance staff and lower balance staff is equipped with leading wheel seat, It is characterized in that bottom shaft rear end is fixedly connected with lower swing seat, lower swing seat is associated with connecting rod, and small end is associated with mounting base, fixed in mounting base There are spline housing, the rear end of upper balance staff to be fixedly connected with splined shaft, splined shaft sliding is set in spline housing.

The upper balance staff of the present invention is coordinated by splined shaft and the spline housing being connected on lower balance staff, when cross saddle passes through branch When seat drives upper balance staff to move along its axis, the equal remains stationary such as lower balance staff and spline housing is not necessarily to two level compared to existing structure Articulated mounting, not only structure is relatively easy, installs, is easy to use, and wears small, it is ensured that processing quality；Upper balance staff is along its axis To the swing for not driving connecting rod when movement, axial stroke is only related with the length of splined shaft, without increasing the size of connecting rod i.e. Axial big stroke can be achieved, to realize that steep-taper is processed；

As a further improvement on the present invention, small end is equipped with sliding slot, and mounting base is fixedly connected with sliding block, and sliding block passes through locking Screw is coupled in sliding slot；By adjusting position of the sliding block in sliding slot, the spacing of upper balance staff and lower balance staff can be changed, improve general Property；

As a further improvement on the present invention, lower swing seat with connecting rod by being hingedly connected；When the stroke of splined shaft is to both ends When point, the swingable certain angle of connecting rod can expand the stroke of upper balance staff axial movement, realize the processing of steep-taper；

In conclusion the present invention has the advantages that structure is relatively easy, installs, is easy to use, and wear small, it is ensured that add Working medium amount and realization steep-taper processing.

Description of the drawings

Fig. 1 is the front view of the embodiment of the present invention.

Specific implementation mode

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in Figure 1, the rocker frame mechanism of the wire cutting machine tool taper head, including upper balance staff 1, lower balance staff 2 and upper balance staff 1 The front end of the bearing 3 connected firmly, the support base 4 being placed on lower balance staff 2, upper balance staff 1 and lower balance staff 2 is equipped with leading wheel seat 5, the bottom 2 rear end of axis is fixedly connected with lower swing seat 6, and lower swing seat 6 is hingedly associated with connecting rod 7 by hinged shaft 13, and 7 upper end of connecting rod is equipped with sliding slot, an installation Seat 8 is fixedly connected with sliding block 9, and sliding block 9 is coupled to by lock-screw 10 in sliding slot, and spline housing 11, upper balance staff 1 are installed in mounting base 8 Rear end be fixedly connected with splined shaft 12, what splined shaft 12 slided is set in spline housing 11.

In use, support base 4 is connected firmly with rack, bearing 3 couples with the cross saddle of lathe, and bearing is driven by cross saddle 3, bearing 3 drives balance staff 1 to do axial direction again（U axis）Movement and radial direction（V axis）Yaw motion；When doing axial mobile, flower The only sliding in spline housing 11 of key axis 12, descends the equal remains stationary such as balance staff 2 and spline housing 11 at this time；When splined shaft 12 stroke extremely When two-end-point, connecting rod 7 can swing certain angle around lower swing seat 6, can expand the stroke of the axial movement of upper balance staff 1, descend balance staff 2 at this time Remains stationary；When doing radial yaw motion, upper balance staff 1 by splined shaft 12, spline housing 11, mounting base 8, sliding block 9, connecting rod 7, Lower swing seat 6 pushes lower balance staff 2 to do radial yaw motion in support base 4, to realize taper WEDM；The present invention is compared to existing There is structure, be not necessarily to two level articulated mounting, not only structure is relatively easy, installs, is easy to use, when cross saddle passes through 3 band of bearing When dynamic upper balance staff 1 moves along its axis, splined shaft 12 wears smaller, can protect in the swing that spline housing 11 slides and connecting rod 7 is a small amount of Demonstrate,prove processing quality；Its axial stroke is mainly related with the length of splined shaft 12 when upper balance staff 1 moves along its axis, without the company of increasing Axial big stroke can be realized in the size of bar 7, to realize that steep-taper is processed；It, can by adjusting position of the sliding block 9 in sliding slot The spacing of balance staff 1 and lower balance staff 2 in change improves general.
