Abstract
The use of semi-automatic devices grown mainly in areas that require precision and systematization of processes, due to safety and reliability of automated processes. This work aims to design and build a device to support and motion sensors, called sensor's positioner. With proper device inertia moment calculations and stepper motor torque, the theoretical part of the project was built, thus ensuring the device structure as closely as possible to the idealized. Two aluminum plates were used to support and give structure to a system composed of a trapezoidal screw and two guides. From the center of a plate to the center of the other, the spindle is the main element. A radial bearing to support the load and the rotation of this element was used. The guides follow the same spindle orientation. Coupled to the other end of the spindle, a stepper motor generates the required rotation for the vertical displacement of a mobile device, which is called nut. As the spindle rotates, the nut which is attached to the two guides and seated in a spindle nut-screw system, has a limited rotation, generating only vertical displacement. The automation of this device was taken using Arduino, which is responsible for systematizing the stepper motor rotation, allowing accurate positioning of the sensor. The calculations of engine torque and moment of inertia positioner provided a normal operation of the device, as designed, which certainly will be very important and useful for the study and development of mechanical devices.
