【 摘 要 】

The aim of this paper is to design a high precision platform of double freedom which can control speed and limit travel. In order to make the structure compact and not bloated, the gear transmission is chosen as the transmission mode in this paper. In order to accurately control the speed and limit the stroke, the stepping motor has become the first choice of motor design. The stepper motor can be used as the power source not only to build an open-loop control system with simple structure but also to set up a closed-loop control system with higher control precision. Based on this idea, the structure design is completed. After the structure design is finished, the finite element method is used to analyze the individual parts. To confirm the reasonableness of the structure.
