Fixedly install bearing cap on bracket shell, the gap adjustment nut is threaded with bearing cap, and the 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 adjustment nut that is threaded, the end face of adjusting nut compresses hollow worm screw.
Outside bulging joining sleeve and adjustment nut protecting cover is set, protecting cover is fixed on the 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 drive part are arranged in the bracket shell, can realize comprehensive 360 ° of accurate rotation positioning, have that compact structure, antidumping moment are strong, velocity ratio big, low return difference, drive gap are easy to adjust, long service life advantage.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Fig. 1 is a structural representation schematic representation 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 of band 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, 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 the 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, bearing 11 1 sides are provided with gap adjustment nut 12, and gap adjustment nut 12 is threaded with bracket shell 2.As fixedly install bearing cap 13 on bracket shell 2, 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 adjusting nut 15 compresses hollow worm screw 9.Outside bulging joining sleeve 10 and adjustment nut 15 protecting cover 16 is set, 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 that vertical orientations is adjusted is by miniature reducer 18, drive vertical transmission worm screw 4 motions, vertical transmission worm screw 4 is designed to a worm screw 8 and 9 two parts of hollow worm screw, connect by bulging joining sleeve 10, axle worm screw 8 and hollow worm screw 9 drive vertical transmission worm gear 5 runnings together, and vertical transmission worm gear 5 drives output shafts 1 rotation, make the workpiece that is installed on the output shaft 1 such as heliostat rotation positioning in vertical direction.The adjustment process of vertical transmission worm screw 4 axial clearances is: will adopt gap adjustment nut 12 screw-ins of slotted nut to establish 2 li of the bearing caps of internal thread, by rotary gap adjusting nut 12, promote packing ring 21 and compress bearing 11, make vertical transmission worm screw 4 no axial clearances, the nut of counterrotating gap adjustment then 12 several angles, reserve the necessary axial clearance of vertical transmission worm screw 4 runnings, locking is arranged on the screw 14 on the gap adjustment nut 12 again, locks the adjustment that bulging joining sleeve 10 is promptly finished vertical transmission worm screw 4 drive gaps at last.By screwing the adjustment nut 15 that a worm screw 8 one ends are provided with, also can change the position to axial of a worm screw 8 and hollow worm screw 9, make vertical transmission worm screw 4 reach the needed gap of work with the back lash of vertical transmission worm gear 5.Equally in working order down, the motor 19 that level orientation is adjusted drives horizontal transmission worm screw 6 motions by miniature reducer 20.Because horizontal transmission worm gear 7 is fixedly mounted on the stationary axle 22 that fuses 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 positioning 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 only is that the preferred implementation to integral multifunctional positioning and driving mechanism of the present invention is described; be not that the design and the scope of inventing limited; under the prerequisite that does not break away from the present invention program; 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 and driving mechanism of the present invention.
