Zaključna naloga obsega analizo hidravlične prototipne naprave za avtomatsko strego in pozicioniranje obdelovancev. V prvem delu naloge so podrobneje predstavljene uporabljene hidravlične in krmilne komponente ter opisane tri vrste hidravličnih ventilov, in sicer običajni proporcionalni, regel in servo ventili, ki se uporabljajo za odprto-zančno in zaprto-zančno krmiljenje pozicije batnice hidravličnega valja. Glavni del naloge predstavlja eksperimentalna analiza hidravličnega krmiljenja, pri kateri smo analizirali osnovne karakteristike sistema, kot so hitrostni profil pri različnih obratovalnih pogojih in pozicijska ločljivost. V sklopu eksperimentov smo določili tudi optimalne krmilne parametre za PID regulacijo pozicije hidravličnega valja. V zadnjem delu naloge je predstavljen koncept realnega strežnega sistema in krmiljenja za avtomatski razrez kosov.

• Title: Analysis of hydraulic drive for automatic handling

Abstract

This Bachelor's thesis covers the analysis of a hydraulic prototype drive for automatic handling and positioning of workpieces. In the first part of the thesis, the hydraulic and control components used are described in detail and three types of hydraulic valves are described: the conventional proportional, the direct-drive servo solenoid and the servo valves that are used for open-loop and closed-loop control of the position of the hydraulic cylinder piston rod. The main part of the thesis is the experimental analysis of the hydraulic control, in which we analyzed the basic characteristics of the system such as the speed profile at different operating conditions and position resolution. As part of the experiments, we also determined the optimal control parameters for the PID control of the position of the hydraulic cylinder. In the final part of the thesis is presented the concept of a real handling system and control for automatic cutting of pieces.
