Robotic manipulation with Laser Welded Common Rail during the laser welding process
Bužga, Petr ; Šubrt, Kamil (referee) ; Knoflíček, Radek (advisor)
This master’s thesis deals with a description of Laser Welded Common Rail, which is produced by the company Bosch Diesel, s. r. o. in Jihlava. The theoretical part is focused primarily on a proposal for an industrial robot which would be manipulated with Common Rail during the laser welding process. The practical section is concerned with changes in the current paths of the robot to reduce production times, and to avoid using the same parts of the robot for the whole duration it is being manipulated with the Common Rail. At the end of this master's thesis is a techno-economic evaluation of previous alternatives, and it determines the appropriate option for robotic manipulation with the Common Rail during the laser welding process.

Drive system by serial connection of rotary hydromotors
Pokorný, Pavel ; Knoflíček, Radek (referee) ; Omes, Jiří (advisor)
The thesis deals with the problem of large-capacity manipulation of large forgings with forging manipulator. It describes current techniques, their characteristics, advantages and disadvantages. Based on the analysis of these techniques, the thesis introduces design of the connection of the hydraulic circuit for the drive of the traveling traction wheels of the forging manipulator QKK 100 by ŽĎAS a.s. focusing on simplicity, trouble-free operation, efficiency, economy, change of speed and torque, and possibility of modification according to the current load.

Mobile turning machining center with vertical workpiece axis
Pomikálek, Adam ; Knoflíček, Radek (referee) ; Marek, Jiří (advisor)
The subject of this diploma thesis is the conceptual design of a mobile lathe centre with a vertical workpiece axis. First, a search in the field of mobile lathes, stationary lathes and methods of their transport is performed. Then, from the described transport machine options, the most suitable transport variant is selected, thanks to which variants of the mobile machine solution are created. Subsequently, the design of the winning variant is fully adapted to the method of transport using containers. Emphasis is placed on simple construction, maximum use of the transport packaging in the machine frame and easy assembly of the machine customer. For these reasons, the machine frame must consist of two containers. Finally, the assembly and adjustment of the machine tool are solved in combination with the verification of the functionality of the proposed concept.

Design of mobile horizontal wood-splitting machine
Dressler, Jan ; Škopán, Miroslav (referee) ; Knoflíček, Radek (advisor)
This thesis shows making of documentation for production powerfull wood-splitting machine for hardest forestal work. There are researched and soluted all phases of pre-production machine's lifecycle, also means analysis of conception, potentional risks and failures analysis and also definition of required properties. Based on those properties and results of analyses is possible to setting up condition which should be satisfied. At following part are descripted and shown features of machine-design . Main feature (component) of machine is its frame, also there are strenght analysis of frame. Machine movement features are mainly hydraulics pistons which are powered by asynchronous engine, whith alternative possibility movement by wheel tractor power-take off shaft or hydraulics output. There are performed all important properties. Working safety questions and high endurability of machine shold be also performed. At the end of work is realised conception and design study of forestal production system for wood processing with one universal source of energy – wheeled tractor.

Stiffness of Industrial Robot Arm
Vogel, Jan ; Jurčišin,, Miroslav (referee) ; Knoflíček, Radek (advisor)
Stiffness analysis of an arm of an industrial robot with linear kinematics during a drilling operation. For solving this problem are used optical scanners. Finding the optimal cutting force for drilling by criterions: minimal deformation of robots arms and, at the same time, the emerging vibration from the cutting process is also minimal.

Hydraulic heating press with nominal force 600 kN
Tyburec, Adam ; Knoflíček, Radek (referee) ; Omes, Jiří (advisor)
This bachelor thesis contains a design of a hydraulic heating press. That includes the calculation of the press drive, the design of the hydraulic circuit, the analytical calculation of the hydraulic cylinder and the optimization of the press frame by FEM. Drawing of a press assembly, drawing of a hydraulic cylinder assembly and detailed drawings of selected components are made based on these results. At the end a simplified maintenance plan is created.
