Abstract

Ovaj završni rad bavi se konstrukcijom fraktalne stege s motornim pogonom, koja omogućava
čvrsto i precizno stezanje objekata različitih oblika i dimenzija. Fraktalne stege, čiji dizajn
proizlazi iz fraktalne geometrije, omogućuju prilagodljivo stezanje i ravnomjerniju raspodjelu
naprezanja, čime smanjuju rizik od oštećenja obratka.
U radu se najprije analiziraju postojeća konstrukcijska rješenja fraktalnih stega, ocjenjuju
njihove prednosti i nedostaci te se izrađuju koncepcijska rješenja s ciljem postizanja
optimalnog dizajna. Odabrano rješenje detaljno je razrađeno kroz proračune pogonskog
sustava, uključujući određivanje parametara elektromotora, prijenosnog mehanizma i sistema
stezanja. Također, komentira se oblikovanje i čvrstoća čeljusti i okvira stege kako bi se
osigurala mehanička otpornost i dugovječnost uređaja.
Cilj rada je razviti funkcionalno, učinkovito i konstrukcijski izvedivo rješenje fraktalne stege s
motornim pogonom, koje bi moglo pronaći praktičnu primjenu u industriji i obrtništvu.

Abstract (english)

This thesis focuses on the design of a motor-driven fractal clamp, enabling firm and precise
clamping of objects of various shapes and dimensions. Fractal vises, whose design is derived
from fractal geometry, allow for adaptive clamping and even stress distribution, thereby
reducing the risk of workpiece damage.
The study first analyses existing structural solutions for fractal vises, evaluates their
advantages and disadvantages, and develops conceptual designs to achieve an optimal
solution. The selected design is thoroughly elaborated through calculations of the drive
system, including the determination of motor parameters, transmission mechanism, and
clamping system. Additionally, the design and strength of the vise jaws and frame are
discussed to ensure mechanical durability and long service life.
The goal of this thesis is to develop a functional, efficient, and structurally feasible solution
for a motorized fractal vise that could find practical applications in industry and
craftsmanship.
