Designe of spindel for miling centre
Žebrák, Matěj ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The thesis deals with the design and construction of the spindle of the milling centre. The aim of the thesis is to design an indirect drive spindle with an output power of about 25 kW and a tool interface HSK 63. In the design part, first the selection of the drive method and spindle mounting is made. The selected structural design is then elaborated in detail using the necessary structural calculations supported by strength-deformation and modal FEM analysis. The output of this work is a 3D model of the spindle and drawings of the selected nodes.

Design of single-purpose assembly machine for assembly of gas distributor in gas grill
Procházka, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Objective of this thesis is creating the construction of one-purpose assembly machine for combination of gas switchboard in gas grill assembly, which is top part of the gas cooking grill, consisting of stainless steel plate and burners. There are three types of burners, one small type, two medium types and one big type. Each consists of aluminium body, nozzle, ignition electrode and gas leakage protection fuse. Prior to construction itself, variant solutions of the assembly operations arrangement are designated. From those, the most appropriate one is chosen based on multicriteria weighting method. Construction of assembly line is created using 3D modelling program with necessary design calculations. For selected assemblies and parts, a drawing documentation has been created. Risk analysis and security of the machine’s normal operation is an integral part of the thesis. Risk analysis is created for the machine’s normal operation. In conclusion, the costs of purchasing the assembly line are calculated and the return of the investment for purchasing the machine is assessed.

Design of working arm for threading machine
Radil, Filip ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
The aim of this bachelor thesis is a design of a working arm for a threading machine. The arm has to keep required axis orientation of the tool in the entire workspace, and in addition it has to compensate the weight of threading machine and absorb the reaction forces from the thread which is being cut. The thesis also contains a research part into reaction arms, calculations report of main parts, 3D model of arm and drawing documentation of main parts.

A design of pneumatic stationary chuck
Hurtík, Daniel ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This Bachelor’s thesis is focused on the construction of a pneumatic stationary chuck, but it also mentions something in the field of workpiece clamping and machine vices for rotating workpieces. The first part contains a brief search in the field of clamping, which focuses mainly on the clamping of rotating parts. The next chapter focuses on possible solutions that would meet our requirements. The main components of the chuck are then calculated and designed so that subsequent construction can be performed in any CAD software, which is the content of the next chapter. Finally, some requirements for chuck operation are summarized.

Design of segment sheet bender
Romanov, Dmitrij ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The bachelor's thesis deals with the design of a manual segment sheet metal bending machine. Part of the work is a theoretical analysis of the current state of science and technology in the field of material bending. The design solution of the segment bending machine is based on similar machines currently available on the market, which are analysed in this work. Then the possibilities of the construction of important parts of the bending machine are proposed, which are then evaluated for the selection of a suitable variant. The bending machine is designed for bending low-carbon steel sheets suitable for cold forming with dimensions up to 1550 x 2 mm.. The work contains calculations of the control parts of the machine, which are based on the selected material for bending. Afterwards a 3D model of the bending machine and drawing documentation of the assembly and its selected nodes are developed.
