Fig. 2 is the main sectional view of the syndeton of the utility model and machining center slide and crossbeam.
Fig. 3 is the top view of the syndeton of the utility model and machining center slide and crossbeam.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.Machining center milling head parts relief arrangement, is made up of bearing holder (housing, cover) assembly, slip cap assembly and positioning sleeve 8.
As shown in Figure 1, Figure 2, Figure 3 shows, the structure of machining center milling head parts relief arrangement is: bearing holder (housing, cover) assembly is form by the cylindrical of bearing 2 being equipped with a bearing holder (housing, cover) 3.Slip cap assembly is put for disk spring 5 being arranged on slip cap 6 upper surface open slot by mandrel 4, adopts this disk spring can bear the very large axial load of excursion, and the deformation energy of its unit volume is comparatively large, has and cushions vibration absorption ability preferably.Mandrel 4 and slip cap 6 Internal hole positioning.The structure of bearing holder (housing, cover) assembly and slip cap assembly is: by the through hole of bearing pin 7 in the middle of bearing 2, whole bearing holder (housing, cover) assembly is fixed on slip cap 6 internal cavity end, the contact surface of slip cap 6 and bearing 2 is provided with an adjustment pad 12 for space between regulating, is provided with one and adjusts pad 12 bearing can be regulated at the tightness of sliding shoe inside.The length of bearing pin 7 is greater than the diameter of slip cap 6, and is less than the diameter of positioning sleeve 8, and only in this way guarantee slip cap assembly slides up and down at positioning sleeve 8 endoporus.The structure of slip cap assembly and positioning sleeve 8 is: slip cap 6 is arranged on positioning sleeve 8 lower end inside cavity, and slip cap black box can slide up and down along positioning sleeve 8 endoporus; Being provided with one in the upper surface screwed hole of positioning sleeve 8 can the adjustment screw 9 of precession screwed hole, the adjustment end of screw 9 and the tip contact of mandrel 4, adjustment screw 9 is soket head cap screw, the upper surface that whole screw 9 exposes positioning sleeve 8 surface is also rotary with a locking nut 11, the lower surface of locking nut 11 contacts with the upper surface of positioning sleeve 8, arranging locking nut 11 can when adjusting screw, and enlarged contact areas, improves stability.
In order to realize the function of this machining center milling head parts relief arrangement better, the main sectional view of syndeton and top view if Fig. 2, Fig. 3 are the utility model and machining center slide and crossbeam respectively: be two covers when this relief arrangement 1 reality uses, be individually fixed in the installing hole of slide 13 the right and left; Fixed form is: positioning sleeve 8 is fixed in installing hole by holding screw 10, and the lower surface of relief arrangement bearing holder (housing, cover) 3 contacts with crossbeam 14 upper rail face.
The using state of this machining center milling head parts relief arrangement: after this device installs, when needing off-load, by the adjustment screw 9 above screwing-in device, adjustment screw 9 can apply pressure to mandrel 4, mandrel 4 can pass to bearing holder (housing, cover) 3 pressure again, final bearing holder (housing, cover) 3 pairs of crossbeam 14 upper rails apply certain active force, namely the decrement of disk spring 5 is controlled well by adjusting the screw-in of screw 9, thus control the contact force of bearing holder (housing, cover) 3 and crossbeam 14 upper rail, the size of this active force can offset the active force of part milling head parts, thus reaches the effect of off-load.When without the need to this relief arrangement practical time, screw out adjustment screw 9, bearing holder (housing, cover) 3 is not contacted with crossbeam 14 upper rail.
