Abstract

Tema ovog diplomskog rada je konstruiranje naprave za pozicioniranje pri zavarivanju radi smanjenja vremena i povećanja kvaliteta zavara. Naprava će se prvenstveno koristiti za zavarivanje okvira nosive konstrukcije proizvoda. Okvir je velikih dimenzija sastavljen od velikog broja dijelova. Pomoću naprave biti će moguća manipulacija okvirom, odnosno njegova rotacija, zakretanje i podizanje. Nadalje, od naprave se očekuje jednostavno i sigurno rukovanje. U radu su, na temelju definiranih zahtjeva, osmišljena tri koncepta od kojih je vrednovanjem odabran najbolji. Uslijedila je konstrukcijska razrada u obliku proračuna kritičnih dijelova i izrade CAD modela u programu Siemens NX te izrada tehničke dokumentacije.

Abstract (english)

The topic of this thesis is to design of device for positioning during welding in order to reduce time and increase the quality of the weld. The device will primarily be used for welding the frame of supporting structure of the product. The frame has large dimensions and it is made of large number of parts. Using the device, it will be possible to manipulate the frame, i.e. rotation, tilting and lifting. Furthermore, simple and safe handling is expected from the device. In the paper, based on the defined requirements, three concepts were designed, of which the best one was selected through evaluation. This was followed by construction elaboration in the form of critical parts and the design of CAD model in the Siemens NX program, as well as the creation of technical documentation.
