Design of a headstock for a machine tool
Sehon, Tomáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This master’s thesis deals with design of a headstock for a machine tool. Theoretic part of this thesis provides basic description of a horizontal machine tool. Further it is dedicated to description of a headstock of machines with extensionable work spindle. In a design part firstly optimal variant is chosen by using multicriterial analysis. Necessary calculations were done and chosen variant was developed. Design is realised by 3D CAD model and drawing documentantion.

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.

Design of linear axis for heavy machine tool
Göbel, Lukáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.

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.

Modular linear axis
Chlapečka, Tomáš ; Bilík, Martin (referee) ; Pavlík, Jan (advisor)
This thesis contains a structural design of linear axis with a stroke up to 800mm and a maximum load of 800N. The thesis also deals with a modular assembly system of the linear axis based on the structural design. Linear axes can be fitted with rolled, whirled and grinded ball screws with thread pitch 5, 10, 16mm and rolled trapezoidal screws on pitch 4 and 8mm. The stroke of the linear axes can be selected in the range from 200 up to 800 mm, with a maximum load of 800N in all linear dimensions. The feed of linear axis is provided by shaped rolling guide way and four trucks. The modular system offers two servo motors with direct and indirect measuring four stepper engines with indirect measuring. The thesis also includes strength and functional calculations of principal components, graphs of the possible load on linear axis in different positions , durability of the ball screws, maximum speed and feed rate of the chosen screws, data sheet, 3D model, drawings and assembly drawings of the nodes.

Drive and leading of laser pointer
Dostál, Petr ; Studený, Jiří (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with a construction solution for traversing of laser pointer, which is used for position identification for stock removal from the storage unit SSI Logimat, including a construction solution of leading of this traversing. The first part contains a research of storage systems used in logistics, as well as systems upgraded with laser pointer. In main part are described the suggestions of leading of laser pointer traversing, together with the design of mechanical transmission and components associated with mechanical transmission. Subsequently the drive of spin of the laser and drive of mechanical transmission are designed. Selection of drives is verified by calculation. The final part contains the check of leading of traversing by strength calculation for bending, from which is suggested the design of leading reinforcement.

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.
