Welding manipulator construction design
Fuks, Šimon ; Tůma, Zdeněk (referee) ; Štěpánek, Vojtěch (advisor)
This bachelor thesis deals with the design of a five-axis welding manipulator as an additional device to a welding table. The research focuses on knowledge from arc welding automation, especially on the use of industrial robots and manipulators in this area. A rich selection of accessories for robotic arc welding is also summarized. In the practical part, several conceptual variants are proposed, and the most suitable variant is further developed. The basic technical calculations of the manipulator are presented and the individual construction details are discussed. Furthermore, the work deals with the safety and control possibilities of the designed manipulator. The work also includes a drawing of the overall assembly.

Design methodology for the selection of basic components of linear machine tool axes
Král, Stanislav ; Dosedla, Michal (referee) ; Holub, Michal (advisor)
The aim of the thesis is based on specified parameters positioning units, which include stroke (1m, 2m, 4m), load (5kg, 50kg, 500kg), you place the position accuracy (0.04 mm) and dynamic (maximum attainable speed 1.5 m / s), proposals to build a ball screw, linear motor, a toothed belt and toothed comb. For selected variants of positioning units to design a 3D model of positioning units. The proposed variations to compare and define their advantages / disadvantages, techno-economic comparison, the limit values of individual designs, etc. The work includes a search drive in positioning units, design units with toothed belt, a toothed comb, ball screw linear actuator, a calculated message of individual proposals then 3D design options for the ball screw and linear motor including drawings and assembly drawings.

Positioning of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis
Grepl, Martin ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The thesis deals with the positioning of the tilting head of the multifunctional milling centre in three axis. The aim of the thesis is to design a multifunctional milling machine centre with a horizontal axis of the spindle in cooperation with Bc. Ľubomír Vazovan, Bc. Ján Rapčan a Bc. Tomáš Hynšt, who are working on the issues of the headstock, automatic tool change and palletization. The thesis also contains proposals of certain options and their subsequent evaluation by the multicriterial method PATTERN. The resulting construction is complemented by calculations of the main construction nodes.

Design of a three-axis manipulator
Vojtěch, Michael ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
The goal of master’s thesis is design of a three-axis manipulator working as x-ray unit. Axis include one rotary and two liner. The work is based on the existing manipulator and the goals are reducing vertical installation space, weight reduction, increasing accuracy and repeatability. Creating 3D model with computational report from available components. There is resulting variant solved with linear motor in this thesis with that there is indicated alternative variant but not dealt with in detail.

Design of a two-axis multi-spindle lathe carriage
Sedlář, Jiří ; Štěpánek, Vojtěch (referee) ; Hadraba, Petr (advisor)
This diploma thesis deals with the design of a two-axis multi-spindle lathe carriage. In the first part, there is made a research, and its aim is to find possible variants of design solutions. After the best rated variant was selected, the thesis further continues with the necessary technical calculations of the main design nodes such as a synchronous servomotor, ball screw, linear guide and bearing. The design itself was carried out with regard to calculations and the resulting model was examined in terms of dynamic stability. The subject of examination was to find the natural frequencies of the assembly and to determine the amplitudes of the oscillations which arise from the harmonic excitation force. Finally, Lobe diagrams for grooving and longitudinal turning operations were drawn.
