Embodiment
A kind of double freedom platform, the worm screw 3 that the axle of motor 1 go up to be provided with forms transmissions with worm gear 5 engagements that are arranged in this casing after passing a wall of upper box 8, last axle 10 vertically passes the center of worm gear 5, fixedlys connected with two side plates of support 7 respectively after passing casing by the bearing that is arranged on upper box 8 sidewalls in two ends.Last axle 10 can or utilize two side plates of pin or nut clamping mode and support 7 to fix by welding.The worm screw 4 that the axle of motor 2 go up to be provided with forms transmissions with worm gear 6 engagements that are arranged in this casing after passing a wall of lower box 9, lower shaft 11 vertically passes and protrudes upward lower box 9 upper walls behind worm gear 6 centers and penetrate in the upper box 8 and with upper box 8 and fixedly connected, can pass worm gear 6 downwards and get final product, also can pass lower box 9 by the bearing on lower box 9 diapires.Lower shaft 11 can be by pin with upper box 8 Placements, also can be by the mode of lower shaft 11 in place welding of passing casing 8 lower walls or nut clamping connected.Last axle 10 is fixedlyed connected with worm gear 6 with worm gear 5 respectively with lower shaft 11, and its Placement can be welding, also can be to be threaded; Or a prominent axle is set in the center of a side of worm gear, and on prominent axial wall, be provided with elongated opening, will go up axle 10 with screw and clamp then and lower shaft 11 is clamped on this prominent.The set-up mode of worm screw 3 and worm screw 4 can be to be stuck on the motor shaft by corresponding grooves and projection, also can be to use dowel fixes, or be threaded, and can also worm screw directly be set to the part of motor shaft when producing motor.
Worm gear 5 is parallel with two side walls of last axle 10 upper boxes that pass 8 as far as possible, and 6 on worm gear is vertical as far as possible with worm gear 5, and is accurately reliable to guarantee transmission.
Be equipped with groove and crossette on the face of worm gear 5 and worm gear 6, limiting board 12 is stuck on the crossette by screw and recess part with himself fixedlys connected with worm gear.Placement can also be not establish crossette, directly uses several screws, or utilizes binding material that limiting board 12 is fixed on the worm gear.Photoelectricity assembly parts 13 is fixed on casing 8 and casing 9 inwalls and the limiting board 12 corresponding positions, so that worm gear 5 and worm gear 6 be when rotating, the bead of limiting board 12 just by the switch of photoelectricity assembly parts 13, is externally transmitted signal.Photoelectricity assembly parts 13 can be welding with the means of fixation of box body wall, also can be to utilize the binding material bonding, or utilize the clamping of slotting on the box body wall.Said photoelectricity component 13 is made up of circuit board and optoelectronic switch.
The middle part of lower shaft 11 is empty, line box 14 is set on the outer wall of lower box 9, the various lines of motor 1 and photoelectricity assembly parts 13 can pass the back by being provided with in the socket tie-in line box 14 on the online box 14 through the hollow space of lower shaft 11, and are connected with the control corresponding device respectively behind leading-out wire box 14.The various lines of motor 2 then need not process lower shaft 11 and direct tie-in line box 14, and are connected with the relevant controlling device after drawing.
During use, open motor 1 or/and 2, then worm screw 3 is or/and 4 rotate under driven by motor and rotation passed to worm gear 5 or/and 6, and worm gear 5 is or/and 6 drive and go up axle 10 or/and lower shaft 11 rotates.Fixedly connected with support 7 owing to last 10, support 7 is also along with swing within the specific limits; And, because lower shaft 11 is fixedlyed connected with upper box 8 and can be driven it and rotates in a horizontal plane, and upper box 8 can rotate in a plane by last axle 10 drive supports 7, support 7 just both can be swung in a vertical plane like this, can separately or rotate in a horizontal plane simultaneously again.Here on said vertical plane and the horizontal plane concrete condition of placing according to whole device and fixed.When carrying is placed and is fixed on the support 7, also just along with support 7 is done corresponding motion.
And, because the bead of limiting board 12 is through the switch of photoelectricity assembly parts 13, whenever, will send photosignal one time through an optoelectronic switch 13, this signal is integrated the back through the photoelectricity assembly parts and is passed to controller by elastic cable paper, thereby controls the pivotal position of The Cloud Terrace in two planes by controller calculating and by the rotation of control motor.
In order to improve the validity of control, motor 1 of the present invention and motor 2 are stepper motor, the double freedom platform worm gear transmission ratio of the specific embodiment of the invention is 70: 1, uses the stepper motor of model as 42BYGH423B (JB), and the The Cloud Terrace precision is 0.0129 °.
