This master’s thesis defines and closely specifies actual trends in clamping systems for shank tools, especially used for milling and drilling operations. The project describes possibilities of application of clamping systems for shank tools for particular types of machining and briefly defines their principles. Experimental part is focused on material analyse of hydraulic and thermal clamping system. Comparing of clamping systems in term of their technical properties and their initial costs is included in technical and economical conclusion.

This thesis descibes questions of tools for production of shape hollows focused especially on milling and electroerosion machining. Here you can find individual tools included their description and characteristics, toolmakers and their news. Here are mentioned methods and contemporary trend of cutting. Here is comparison of several tools in concrete applications. Included is also list of basic types of milling tools clamping. In conclustion there is mentioned further development of tools and their using.

Diploma thesis deals with the concept of interchangeable straight spindle head type VA1-C, used for automatic clamping in 80 kW spindle head from production of TOS Kuřim. Thesis contains survey of interchangeable heads, analysis of the spindle housing, strenght analysis of the spindle with the safety calculations in critical sec-tions and analysis of the clamping mechanism together with the calculation of the camping force, which holds the tools in the spindle. Analysis of the camping mechanisms contains calculation of the contact stress between balls and housings. All results are shown in the graphs. In the last part of the thesis are described the construction elements using the model of the interchangeable head. Enclosed is the assembly drawing of the spindle head, bill of material, detail drawing of the spindle and also 3D model of the interchangeable spindle head.

The aim of this diploma thesis is to design manipulator for handling tools and tool heads between two tool’s magazines of the two vertical machining centers. One part of this thesis is a proposal of solutions, selection of the optimal choice, its construction and technical calculations of some construction nodes. Other parts of this thesis are technical drawings. The technical drawing of assembly, and two technical drawings of main components.

Práce se zabývá změnou výrobního procesu výroby tlakového zásobnku system Common Rail. Předmětem práce je take návrh a úprava upínacího přípravku pro výrobu kovaných tlakových zásobníků pro obráběcí centra ELHA.

This Master thesis deals with design structures of moving bolster for body panel press and with design of railroad tracks, in which the bolster is moving in two mutually perpendicular directions. These moving bolsters are used for facilitating and speeding up the change of pressing dies, which is desirable in automated automotive industry for shortening and streamlining the pressing die change. The part of the work is research of the current state of knowledge in systems for quick die change, design of the moving bolster and its drive, design of railroad tracks, amount of design and control calculations, design of mechanism for lifting the bolster, optimization and strength calculations of bolster in ANSYS software. All the design structures of bolster, railroad tracks and basic workplace layout are processed in 3D software for modelling Autodesk Inventor. Attachments consist of drawing documentation of main assemblies, namely mounting drawing of moving bolster assembly, mounting drawing of railroad tracks assembly, drawing of workplace layout and furthermore drawing of driven shaft, weldment and workpiece of moving bolster and railroad tracks block.
