Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like figure 1 As shown, the driving device based on the externally driven linear stepping motor of the present invention includes an externally driven linear stepping motor 3, and also includes a front screw 2 and a rear end fixedly connected to the rotating parts of the externally driven linear stepping motor 3 Screw rod 5, and front end nut 1 and rear end nut 4 respectively installed on front end screw rod 2 and rear end screw rod 5; front end screw rod 2 and rear end screw rod 5 are coaxial; front end screw rod 2 and rear end screw rod 5 have the same thread direction Or on the contrary, the pitch is the same or different;

[0026] By changing the helical direction of the front-end screw 2 and the rear-end screw 5, the movement directions of the two objects driven by the front-end screw 2 and the rear-end screw 5 are changed; by changing th...

Abstract

The invention discloses a driving device based on an externally driven linear stepping motor. The driving device includes an externally driven linear stepping motor, and also includes a front screw and a rear screw fixedly connected to the rotating part of the externally driven linear stepping motor; the front screw is equipped with a front nut, and the rear screw is equipped with a rear nut; The threads of the front-end screw rod and the rear-end screw rod have the same or opposite direction of rotation, and the same or different pitches. If the front-end screw and the rear-end screw are threaded in opposite directions, and the external-driven linear stepping motor is started on the premise that the rear-end nut is fixed, the external-driven linear stepping motor will drive the external-driven linear stepping motor at the same time. An object fixedly connected to the feeder motor and another object fixedly connected to the front-end nut move in the same direction along the guide rail. The driving device realizes the function of driving two objects to move in the same direction through an externally driven linear stepping motor.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and in particular relates to a driving device based on an externally driven linear stepping motor. Background technique [0002] In daily life and scientific research activities, a linear stepper motor is often used to drive an object to move. To realize the movement of two objects, two linear stepper motors are needed to drive. [0003] In the actual application of engineering, the movement of most associated two objects is relatively simple, for example, two associated objects move towards each other or in the opposite direction at the same time in one direction, but the speed of movement is different; if two externally driven Driven by a linear stepper motor, it not only puts forward higher requirements for the motor installation space and motor control, but also increases the complexity of the entire drive device structure. Contents of the invention [0004] The technical problem to b...
