The detailed content of the utility model is explained in
below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation schematic representation of the utility model.
Fig. 2 is the C-C sectional view of Fig. 1.
Embodiment
are as shown in the figure; The utility model comprises the bracket shell 2 of being with output shaft 1; And control is supported on the bracket shell 2 horizontal driving mechanism that horizontally rotates and the vertical driving mechanism that horizontally rotates direction control output shaft 1 vertical rotation with respect to bracket shell 2 of fixed base 3; Horizontal driving mechanism adopts Worm and worm-wheel gearing with vertical driving mechanism; Horizontal driving mechanism is with in vertical driving mechanism all is arranged on bracket shell 2, and 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 engagements; 7 one-tenth 90 degree of vertical transmission worm gear 5 and horizontal transmission worm gear distribute, and 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 hollow worm screw 9 that comprise mutual grafting; Connect by hollow worm screw 9 outer bulging joining sleeves 10 between axle worm screw 8 and the hollow worm screw 9; Vertical transmission worm screw 4 two ends and 2 of bracket shells are provided with bearing 11 respectively, and bearing 11 1 sides are provided with gap adjustment nut 12, and gap adjustment nut 12 is threaded with bracket shell 2.As on bracket shell 2, fixedly installing bearing cap 13, then gap adjustment nut 12 is threaded with bearing cap 13, and gap adjustment nut 12 adopts slotted nut, and slotted nut is by screw 14 lockings.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 adjustment nut 15 that is threaded, the end face of adjustment nut 15 compresses hollow worm screw 9.With adjusting outside the nut 15 protecting cover 16 is set at bulging joining sleeve 10, protecting cover 16 is fixed on the bearing cap 13.The assembly structure of horizontal transmission worm screw 6 is identical with vertical transmission worm screw 4.In working order down; The motor 17 of vertical orientations adjustment drives vertical transmission worm screw 4 motions through miniature reducer 18, and vertical transmission worm screw 4 is designed to a worm screw 8 and 9 two parts of hollow worm screw;
