Abstract:Robotsko varjenje se v sodobni industriji širi in zamenjuje človeško delovno silo. Ima veliko prednosti pred ročnim varjenjem, zato je sledenje tehnološkim spremembam v podjetjih nujno. Robotske roke je potrebno sprogramirati in jim pripraviti priprave, da so zvarjenci vedno na istem mestu. V podjetju Metalna Senovo, kjer sem tudi štipendist, so kupili varilno robotsko celico. Pobuda je bila, da bi namesto na starih avtomatskih varilnih strojih varili z robotsko roko. Prednosti tega so izboljšana kvaliteta samega vara, krajši manipulacijski časi zaradi avtomatskega obračanja, večja zanesljivost in manj odpadnih zvarjencev. Moja naloga je bila skonstruirati in pripraviti tehnično dokumentacijo za izdelavo pnevmatske priprave za robotsko celico. Pri delu sem uporabljal programski paket Catia, kjer sem uporabljal module za modeliranje, izris načrtov, varjenje ter modul za statične analize. Preračunal sem pomike in primerjalne napetosti po Von Misesu, pri čemer je bilo potrebno upoštevati, da zaradi delovanja sil pnevmatskih cilindrov pomiki na sredini ogrodja varilne priprave ne smejo biti večji od 0,5 mm na strani cilindrov in 0,3 mm na nasprotni strani. Varilna priprava pa mora kljub veliki togosti ostati majhnih dimenzij in lahka.

Title:Construction of platform for robotic welding
Abstract:Robotic welding in modern industry expands every day and replaces human labour. It has many advantages over manual welding, because of that fact tracking of technological change is necessary. Robots need to be programmed and they need platforms. With a platform we make sure that the workpiece stays in the same place every time and through that increase accuracy and repeatability. The company Metalna Senovo, where I had a scholarship has recently bought a welding robot cell. The idea was that instead of the old automatic welding machines, robotic welding should be introduced. Its benefits are better quality improved and reducing manipulation reliability and time due to automatic rotation as well as reducing waste. My task was to construct and prepare technical documentation for a pneumatic platform for a robot cell. At work I use a software package Catia, with modules for modelling, drawing, welding and a module for static analysis. I calculated displacements and von Mises stress. It should be noted that pneumatic cylinders produce a thrust force. Displacements in the centre of the frame should not be greater than 0.5 mm on the side of the cylinder and 0.3 mm on the opposite side. The welding platform must despite its high stiffness, retain its small dimensions and its lightness.
