Design of a forming machine for production of a stainless steel cup with follow die
Staněk, Michal ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
My dissertation describes the procedure and results of designing a single-purpose machine, which is designed for forming a stainless metal product from an initial semi-finished product. This semi-finished product is a 0.28mm-thick stainless-steel plate. The introduction of my dissertation outlines the evolution of the pulling technology in the Czech Republic and abroad and describes its further details. This research part also includes an overview of individual machines according to the CSN. The practical part is then further dedicated to the exploration of individual issues and requirements for designing the machine itself as well as designing the machine according to the requirements of the final pulled product.

Design of station for PCV filter inspection
Tecl, Michal ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
Bachelor thesis deals with the design of a station for automatic visual inspection of the PCV valve filter. The PCV valve is part of the Common rail system, which is discussed in detail in the research part. Furthermore, the principle and capabilities of machine vision are described. In the practical part, several design variants are developed, which are further evaluated. Based on this evaluation, the most suitable variant is selected and then elaborated in detail.

Design of automatic exchange of spindle heads
Srněnský, Jan ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The purpose of this thesis is to design system for automatic exchange of spindle heads shared by several machines. Spindle heads are transported between these machines and placed to the position for exchange. The system also allows storing of heads. Requirements for system are load capacity of 2 000 kg and placing a spindle head to the exchange position with precision of ± 0,02 mm. The thesis consists of three parts. The first part involves search of head exchange principles and shows possible ways to transport heads and other elements that could be used in the system. In the next part are several possible solutions introduced and the selection of the best one is made. The last part contains the design of the chosen solution, visualisation, description and calculations. The result is design of two solutions which are described in this work.

Design and analysis of the cross table
Zemčík, Matěj ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis deals with the design of the cross table. That is, designing a linear guide, a ball screw and a motor. In addition, dynamic simulations are used in the MSC Adams for machining cycle and the positioning cycle of the semi-product at rapid traverse. As a simulation output are the „real“ load patterns of the bearings in the placing of the ball screws and the durability of these bearings.

AC electric linear drive for paralell kinematics structures of robots
Nejedlý, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Design of linear actuator for parallel kinematic structure is described in this master´s thesis. The parallel kinematic structure is described in the first part. Open kinematics structure and close kinematics structure are compared. Their benefits and disadvantages are also mentioned. Construction of some parallel robots is illustrated. Linear actuators of different company are described. Mechanical parameters and construction of linear actuator are compared. Design of linear actuator is described in practical part of master´s thesis. A few variation of linear actuator are introduced. Individual variants are evaluated by Multicriteria Decisional Analysis and a final conception is selected. Final conception of linear actuator is elaborated. Reasons for selection of every part of linear actuator are given and basic mechanical calculation design part is made. FEA analysis of the structural part of linear actuator is made. Design of linear actuator is evaluated in the final part.

Design of belt grinder
Denk, Daniel ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
Aim of this bachelor thesis is to produce a construction proposal of a belt grinder, which is, with respect to universality, adjustable in different axes. Grinding technology, belt grinder principle and description of the functionally important parts are presented in the first part. Second part is dedicated to the market research of existing belt grinders, evaluation of their construction design of an optimal belt grinder. Third part includes the necessary calculations, construction design analysis and economic evaluation of the optimal grinder and the project also contains its proposed 3D model created with Autodek Inventor Professional 2020 model nad drawing documentation.
