Abstract

The invention discloses a swing frame mechanism of a taper head of a linear cutting machine. The swing frame mechanism comprises an upper swing shaft, a lower swing shaft, a support and a supporting seat, wherein the support is fixedly connected with the upper swing shaft; the lower swing shaft is sleeved by the supporting seat; and the front end of each of the upper swing shaft and the lower swing shaft is provided with a main guide wheel seat. The swing frame mechanism is characterized in that the rear end of the lower swing shaft is fixedly connected with a lower swing seat; the lower swing seat is connected with a connecting rod; the upper end of the connecting rod is connected with a mounting seat on which a spline housing is fixedly arranged; and the rear end of the upper swing shaft is fixedly connected with a spline shaft slidably arranged in the spline housing. The swing frame mechanism has the advantages of relatively simple structure and convenience in installation and use and is little in wear and capable of ensuring the processing quality and realizing large-taper processing.

Description

The rocker frame mechanism of wire cutting machine tool taper head

Technical field

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

Background technology

Being currently used for the rocker frame mechanism of Wire cut electric discharge machine rate taper head, many drive by cross saddle is moved, to realize taper WEDM on U axle and V direction of principal axis；Existing rocker frame mechanism, the bearing connected firmly with upper balance staff including upper balance staff, lower balance staff, the support seat being placed on lower balance staff, the front end of upper balance staff and lower balance staff is equipped with leading wheel seat, and upper balance staff is connected by two grades of articulated mountings with lower balance staff；It is complex with the attachment structure of lower balance staff that this device not only goes up balance staff, installs, uses inconvenience, and upper balance staff is when U direction of principal axis moves, and articulated mounting servo-actuated, pin joint can produce and rotate, and the time one, long abrasion was relatively big, produces mismachining tolerance, affects crudy；And at upper balance staff when doing U direction of principal axis and moving, owing to the swing of two grades of articulated mountings need to be relied on to complete, limited by pendulum angle, cause its axial stroke less than normal, it is difficult to steep-taper processing, as strengthened its axial stroke, the size of two grades of articulated mountings must be relatively big, causes the most again using limited.

Summary of the invention

It is an object of the invention to for deficiencies of the prior art, it is provided that the rocker frame mechanism of a kind of wire cutting machine tool taper head, it has, and structure is relatively easy, install, advantage easy to use, and it is little to wear and tear, it is ensured that crudy and realize steep-taper processing.

For reaching above-mentioned purpose, the rocker frame mechanism of the wire cutting machine tool taper head of the present invention, the bearing connected firmly with upper balance staff including upper balance staff, lower balance staff, the support seat being placed on lower balance staff, the front end of upper balance staff and lower balance staff is equipped with leading wheel seat, it is characterised in that bottom shaft rear end is fixedly connected with lower swing seat, and lower swing seat is associated with connecting rod, small end is associated with mounting seat, being installed with spline housing in mounting seat, the rear end of upper balance staff is fixedly connected with splined shaft, and what splined shaft slided is located in spline housing.

The upper balance staff of the present invention is coordinated with the spline housing being connected on lower balance staff by splined shaft, when cross saddle drives upper balance staff to move along its axis by bearing, lower balance staff and spline housing etc. all keep static, compared to existing structure, without two grades of articulated mountings, not only structure is relatively easy, install, easy to use, and it is little to wear and tear, it is ensured that crudy；The swing of not drivening rod when upper balance staff moves along its axis, its axial stroke is the most relevant with the length of splined shaft, it is not necessary to the size adding big connecting rod can realize the biggest stroke, thus realizes steep-taper processing；

As a further improvement on the present invention, small end is provided with chute, and mounting seat is fixedly connected with slide block, and slide block is coupled in chute by lock-screw；By adjusting slide block position in chute, the spacing of upper balance staff and lower balance staff can be changed, improve versatility；

As a further improvement on the present invention, lower swing seat is connected by hinged with connecting rod；When the stroke of splined shaft is to two-end-point, the swingable certain angle of connecting rod, the stroke that upper balance staff moves axially can be expanded, it is achieved the processing of steep-taper；

In sum, the present invention has that structure is relatively easy, installs, advantage easy to use, and it is little to wear and tear, it is ensured that crudy and realize steep-taper processing.

Accompanying drawing explanation

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

Detailed description of the invention

The present invention is further detailed explanation below in conjunction with the accompanying drawings.

As shown in Figure 1, the rocker frame mechanism of this wire cutting machine tool taper head, including upper balance staff 1, lower balance staff 2, the bearing 3 connected firmly with upper balance staff 1, it is placed on the support seat 4 on lower balance staff 2, the front end of upper balance staff 1 and lower balance staff 2 is equipped with leading wheel seat 5, lower balance staff 2 rear end is fixedly connected with lower swing seat 6, lower swing seat 6 is associated with connecting rod 7 by hinge 13 is hinged, connecting rod 7 upper end is provided with chute, one mounting seat 8 is fixedly connected with slide block 9, slide block 9 is coupled in chute by lock-screw 10, spline housing 11 it is installed with in mounting seat 8, the rear end of upper balance staff 1 is fixedly connected with splined shaft 12, what splined shaft 12 slided is located in spline housing 11.

During use, supporting seat 4 and connect firmly with frame, bearing 3 couples with the cross saddle of lathe, cross saddle drive bearing 3, bearing 3 to drive balance staff 1 to do movement and the yaw motion of radial direction (V axle) of axially (U axle) again；Do axial mobile time, splined shaft 12 only slides in spline housing 11, now descends balance staff 2 and spline housing 11 etc. all to keep static；When the stroke of splined shaft 12 is to two-end-point, connecting rod 7 can swing certain angle around lower swing seat 6, can expand the stroke that upper balance staff 1 moves axially, and now descends balance staff 2 to keep static；When doing yaw motion radially, upper balance staff 1 is promoted lower balance staff 2 to do yaw motion radially in supporting seat 4 by splined shaft 12, spline housing 11, mounting seat 8, slide block 9, connecting rod 7, lower swing seat 6, thus is realized taper WEDM；The present invention is compared to existing structure, it is not necessary to two grades of articulated mountings, and not only structure is relatively easy, install, easy to use, when cross saddle drives upper balance staff 1 to move along its axis by bearing 3, splined shaft 12 is in the swing that spline housing 11 slides and connecting rod 7 is a small amount of, wear and tear less, it is ensured that crudy；When upper balance staff 1 moves along its axis, its axial stroke is the most relevant with the length of splined shaft 12, it is not necessary to the size adding big connecting rod 7 can realize the biggest stroke, thus realizes steep-taper processing；By adjusting the slide block 9 position in chute, upper balance staff 1 and the spacing of lower balance staff 2 can be changed, improve general.
