the technical solution adopted for the present invention to solve the technical problems is: comprise the bracket shell with output shaft, and control and to be supported on the horizontal driving mechanism that the bracket shell of fixed base horizontally rotates and to horizontally rotate with respect to bracket shell the vertical transmission mechanism that direction is controlled output shaft vertical rotation, horizontal driving mechanism and vertical transmission mechanism adopt Worm and worm-wheel gearing, horizontal driving mechanism and vertical transmission mechanism are all arranged in bracket shell, vertical-transmission worm screw is arranged on horizontal transmission worm gear one side, horizontal transmission worm gear meshes horizontal transmission worm screw, vertical-transmission worm gear becomes 90 degree to distribute with horizontal transmission worm gear, vertical-transmission worm gear connects output shaft, vertical-transmission worm screw passes outside bracket shell, the axle worm screw and the hollow worm screw that comprise mutual grafting, between axle worm screw and hollow worm screw, by the bulging joining sleeve outside hollow worm screw, connected, bearing is set respectively between vertical-transmission worm screw two ends and bracket shell, bearing one side is provided with gap adjustment nut, and gap adjustment nut is threaded with bracket shell.
on bracket shell, be fixedly installed bearing cap, gap adjustment nut is threaded with bearing cap, and gap adjustment nut adopts slotted nut, and slotted nut is locked by screw.
insert the end of the axle worm screw of hollow worm screw and give prominence to outside hollow worm screw and the adjusting nut that is threaded, the end face of adjusting nut compresses hollow worm screw.
at bulging joining sleeve and adjusting nut, protecting cover is set outward, protecting cover is fixed on bearing cap.
the assembly structure of horizontal transmission worm screw is identical with vertical-transmission worm screw.
the present invention is by above-mentioned specific design, horizontal transmission part and vertical-transmission are partly arranged in a bracket shell, can realize comprehensive 360 ° of accurate rotation location, there is compact structure, antidumping moment is strong, velocity ratio is large, low return difference, drive gap are easy to adjust, long service life.
Accompanying drawing explanation
below in conjunction with drawings and Examples, detailed content of the present invention is described.
fig. 1 is structural representation schematic diagram of the present invention.
fig. 2 is the C-C sectional view of Fig. 1.
Embodiment
as shown in the figure, the present invention includes the bracket shell 2 with output shaft 1, and control and to be supported on the horizontal driving mechanism that the bracket shell 2 of fixed base 3 horizontally rotates and to horizontally rotate with respect to bracket shell 2 vertical transmission mechanism that direction is controlled output shaft 1 vertical rotation, horizontal driving mechanism and vertical transmission mechanism adopt Worm and worm-wheel gearing, horizontal driving mechanism and vertical transmission mechanism are all arranged in bracket shell 2, vertical-transmission worm screw 4 is arranged on horizontal transmission worm gear 7 one sides, the horizontal transmission worm screw 6 of horizontal transmission worm gear 7 engagement, 7 one-tenth 90 degree of vertical-transmission worm gear 5 and horizontal transmission worm gear distribute, vertical-transmission worm gear 5 connects output shaft 1, vertical-transmission worm screw 4 passes outside bracket shell 2, the axle worm screw 8 and the hollow worm screw 9 that comprise mutual grafting, between axle worm screw 8 and hollow worm screw 9, by the bulging joining sleeve 10 outside hollow worm screw 9, connected, 2 of vertical-transmission worm screw 4 two ends and bracket shells arrange respectively bearing 11, bearing 11 1 sides are provided with gap adjustment nut 12, and gap adjustment nut 12 is threaded with bracket shell 2.As being fixedly installed bearing cap 13 on bracket shell 2, gap adjustment nut 12 is threaded with bearing cap 13, and gap adjustment nut 12 adopts slotted nut, and slotted nut is locked by screw 14.Insert the end of the axle worm screw 8 of hollow worm screw 9 and give prominence to outside hollow worm screw 9 and the adjusting nut 15 that is threaded, the end face of adjusting nut 15 compresses hollow worm screw 9.At bulging joining sleeve 10 and the outer protecting cover 16 that arranges of adjusting nut 15, protecting cover 16 is fixed on bearing cap 13.The assembly structure of horizontal transmission worm screw 6 is identical with vertical-transmission worm screw 4.In working order, the motor 17 that vertical orientations is adjusted is by miniature reducer 18, drive 4 motions of vertical-transmission worm screw, vertical-transmission worm screw 4 is designed to axle worm screw 8 and 9 two parts of hollow worm screw, by bulging joining sleeve 10, connect, axle worm screw 8 drives vertical-transmission worm gear 5 running together with hollow worm screw 9, and vertical-transmission worm gear 5 drives output shafts 1 rotation, makes to be arranged on workpiece on output shaft 1 and rotates in vertical direction location as heliostat.The adjustment process of vertical-transmission worm screw 4 axial clearances is: the gap adjustment nut 12 that adopts slotted nut is screwed in to 2 li of bearing caps establishing internal thread, by rotary gap adjusting nut 12, promote packing ring 21 and compress bearing 11, make vertical-transmission worm screw 4 without axial clearance, then counterrotating gap adjustment nut 12 several angles, the necessary axial clearance of reserved vertical-transmission worm screw 4 running, locking is arranged on the screw 14 on gap adjustment nut 12 again, finally locks the adjustment that bulging joining sleeve 10 completes vertical-transmission worm screw 4 drive gaps.By screwing the adjusting nut 15 of axle worm screw 8 one end settings, also can change the position to axial of axle worm screw 8 and hollow worm screw 9, make vertical-transmission worm screw 4 and the back lash of vertical-transmission worm gear 5 reach the needed gap of work.Equally in working order, the motor 19 that level orientation is adjusted, by miniature reducer 20, drives horizontal transmission worm screw 6 motions.Because horizontal transmission worm gear 7 is fixedly mounted on the stationary axle 22 being connected with fixed base 3, horizontal transmission worm screw 6 mounting supports are on bracket shell 2, when horizontal transmission worm gear 7 keeps motionless, horizontal transmission worm screw 6 can be revolved round the sun along fixing horizontal transmission worm gear 7 with bracket shell 2, thereby realizes the rotation location of substantially horizontal.The adjustment process of horizontal transmission worm screw 6 axial clearances is identical with the adjustment process of vertical-transmission worm screw 4 axial clearances, does not repeat them here.Above-described embodiment is described the preferred implementation of Integral multifunctional positioning transmission mechanism of the present invention; not design and the scope of invention are limited; do not departing under the present invention program's prerequisite; various external form modification and improvement that those skilled in the art make technological scheme of the present invention, all should fall into the protection domain of Integral multifunctional positioning transmission mechanism of the present invention.
