Embodiment
Below in conjunction with accompanying drawing, the embodiment of bi-directional synchronization motion central balancing regulating device of the present utility model is described.
Fig. 1 is the structural representation of an embodiment of bi-directional synchronization motion central balancing regulating device of the present utility model, and Fig. 2 is the vertical view of part-structure in Fig. 1.The bi-directional synchronization motion central balancing regulating device of present embodiment comprises the first lead screw guide rails 21 and the second lead screw guide rails 31 that be arranged in parallel, in the first lead screw guide rails 21, be provided with the first nut slider 22, move in the first lead screw guide rails 21 for carrying apparatus measures 23.In the second lead screw guide rails 31, be provided with the second nut slider 32, move in the second lead screw guide rails 31 for carrying balancing weight 33, wherein the quality of apparatus measures 23 and the quality of balancing weight 33 are roughly the same.
The bi-directional synchronization motion central balancing regulating device of present embodiment also comprises driver 15 and the stepper motor 11 that controlled by driver 15, stepper motor 11 is connected and is used for controlling driving gear 12 with driving gear 12, driving gear 12 is meshing with idle gear 13, idle gear 13 is meshing with follower gear 14, wherein the diameter of the diameter of driving gear 12 and follower gear 14 is roughly the same, thereby therefore when rotating, stepper motor 11 drive driving gear 12 while rotating, by the transmission of idle gear 13, follower gear 14 rotates with the speed identical with driving gear 12 and identical direction.Driving gear 12 is connected with the first lead screw guide rails 21, by the rotating drive lead screw guide rails rotation of driving gear 12, thereby drives the first nut slider 22 to slide in the first lead screw guide rails 21.Follower gear 14 is connected with the second lead screw guide rails 31, by the rotating drive lead screw guide rails rotation of follower gear 14, thereby drives the second nut slider 32 to slide in the second lead screw guide rails 31.
