The design of a two-axis manipulator
Soják, Vojtěch ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This master thesis deals with the design of a two-axis manipulator according to entered parameters. In the first chapter provides description of kinematics structures of industrial robots and manipulators and their workspaces. Next parts focus on search in the used components, producers of manipulators and of current design manipulators at JCEE s.r.o. Lanškroun. The practical part deals with the design and construction of custom manipulator and its price calculation.

Design of vibration table
Tuček, Michael ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The main aim of this bachelor thesis is to create a construction plan of vibrating table used for compaction of concrete in molds. First it describes compaction of concrete, after there are listed methods of its consolidation using vibrations. Two variants of vibration drive are created and preferable one is further developed. Individual elements of the structure are designed including their strength analysis.

Design of stend for testing of prosthetic feet
Švachová, Michaela ; Paloušek, David (referee) ; Koutný, Daniel (advisor)
The Bachelor's Thesis first reviews the general body of knowledge related to biomechanics of gait. The paper also provides definition and classification of a lower leg prosthesis together with a review of the most widely used transtibial prosthesis testing methods. The project also provides description and loading conditions of the main d ynamical a nd s tatical t est o f a lower leg p rosthesis a cording t o E N Č SN 10 328. The paper starts with analyzing the problem and continues with construction solutions complaint with testing requirements. The main output of the project is a 3D model of a test stand design with pneumatic actuator created in Inventor 2013 with related calculations in MathCad 14. The project includes also an assembly drawing, drawings of the welded pieces and drawings of other components.

Bidirectional pneumatic stepper motor
Veselý, Václav ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
The diploma thesis Bidirectional pneumatic stepper motor concentrates on a step shaft rotation in the presented scheme of a kinematic mechanism. The introductory research part of the diploma thesis lists various types of pneumatic components and the analysis of elements in pneumatic circuits is provided. The following section of the thesis concentrates on designing a new scheme of a pneumatic stepper and construction of a functional mock-up. The final part of the diploma thesis offers a summary and final evaluation of the design and offers subsequent alterations for its further usage.

Suggestion of a workshop service platform for pneumobil
Suchý, Pavel ; Škopán, Miroslav (referee) ; Hloušek, David (advisor)
The subject of this bachelor’s thesis is a construction design of a mobile scissor lift based on lifting height, platform plate sizes and load capacity. The first part of this thesis studies a comparison of similar lifts. The second part of this thesis deals with a calculation of forces in the lift and a construction of partial components. The pneumatic cylinder is selected for the lifting and a pneumatic circuit is designed. Finally, the drawings of the assembly, drawings of the subassembly and drawing of the partial components are processed.

Safety of automated industrial valves in operating conditions
Kryštof, Ondřej ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.

The construction of electromagnet testing device
Vlasák, František ; Blecha, Radim (referee) ; Knoflíček, Radek (advisor)
Master thesis describes a single-purpose machine design, that is used for testing a basic features of proportional solenoid. The design is created in cooperation with company NUVIA a.s. and contains mechanical solution that is processed in respect with ergonomic requirements, safety and overall costs. Machine concept is affected by customer requirements, whose name, as well as real parameters of the product will not be published, because of non-disclosure agreement.

Equipment for tensioning of mesh on the disc filter segments
Baňoch, Ondřej ; Maňas, Pavel (referee) ; Brandejs, Jan (advisor)
The master thesis deals with mechanical design of device used for stretching and fixing filtration fabric on plastics frames segments for disc filtration device. The thesis was solved in cooperation with IN-EKO Team company that deals with development and manufacturing of filter units. Solution is connected to already ended project FR-T13/699 (end of the year 2013). At the beginning is described the field of filtration devices in broader context with description of the overall functionality these devices and description of used elements in final design. Opening text is followed by concretization of task list and descriptions of concepts variants which are based on FEM analysis of behavior of stretched filtration fabric. The best concept is processed in detail as mechanical design along with pneumatic and PLC control design. Critical part of the design is stretching clamp which was experimentally verified by using experimental clamp in combination with testing machine. The whole design is developed for mass production of disc segments for disc filter which is projected in to the level of the automation.
