Automatická výměna velkých obrobků u obráběcích center
Pomikálek, Adam ; Pavlík, Jan (referee) ; Blecha, Radim (advisor)
The subject of this bachelor thesis describes an automatic workpiece replacement at the machining centres. The description is divided into three chapters. The first chapter deals with clamping and positioning of the technological pallets and workpieces. The second chapter is focused on determination of position of workpieces and on manipulation between the machine and container with assistance of manipulators. In the third part, the thesis aims on containers of the technological pallets and their use in the process of automatic workpiece replacement.

Design of automatic clamping device for CNC milling machine
Jirásek, Jiří ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
This work is focused on the design and construction of a device for automatic replacement of workpieces for CNC milling machines. The thesis contains research in the field of automatic replacement of workpieces. The design itself can be divided into two parts. The first part is the selection of a universal clamping platform and the design of a technological pallet. The second part is the design and construction of the clamping device. First, different design variants are proposed.. These variants are then evaluated by multi-criteria analysis, based on which the most suitable variant is chosen. This is followed by the selection of suitable components for the assembly of the universal clamping platform and the construction of the technological pallet. The main part of the work is the structural design of the pneumatic wedge vice, including the necessary calculations and design of individual components. The output is technical drawings of chosen components and a technical drawing and CAD model of the assembly.

PřekladačVypnout okamžitý překladPalletizing of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis
Hynšt, Tomáš ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis deals with palletization of heavy workpieces that are used by multi-purpose machining centers. The final outcome introduces a suitable option for palletization heavy workpieces of multi-purpose machining centers. In the first part of the thesis is draft of machining centers with parameters which were chosen by exploration of market for selecting suitable solution. The second part of thesis is dealing with a detailed draft palletization made by parts of exploration of market then design palletization system and design pallet changer. The designed construction of pallet changer is dimensioned with help of analytical calculating methods and numerical simulations methods. Outcome palletization system allows automatic change of twenty tons workpieces including pallet between two storage places.

Design of transfer carriage equipped with robot or pallete holder
Tatíček, Vojtěch ; Kočiš, Petr (referee) ; Dokoupil, Vladimír (advisor)
The aim of this work was to design the construction of transport equipment under industrial robot, pallet holder or other equipment. This manipulation device can be moved in one axis on a rigid guide. The device is designed for use in a linear manufacturing system for handling workpieces and tools. It is capable of operating two rows of machines when it is placed in the middle. The main function of this device is to extend the workspace to the carried devices. This type of construction can be used in combination with an industrial robot for other technological tasks such as welding or light machining. The main parts of this device include statically mounted beds that can be stacked behind each other to form optionally long conveyor paths and a positioning plate that moves along the path formed by these beds. An industrial robot, pallet holder or other device is attached to this positioning plate. In addition to the design itself, the thesis also includes a thorough research of the issue, further possibilities of solution in the form of concepts, verification of the structure by means of calculations and simulations and implementation of the solution into a specific production cell.

Automatická výměna malých a středních obrobků u CNC strojů
Tejkl, Michal ; Pavlík, Jan (referee) ; Blecha, Radim (advisor)
The subject of this bachelor thesis is a professional research, dealing with automatic workpiece replacement for CNC machines. The research describes not only the separation of workpiece replacement systems but also the possibility of clamping them. An integral part of AVO is the transport of workpieces between the CNC machine and the tray. The final topic in this work are the trays that extend production times without the need for operator intervention. The reader gains an overview of the possibilities and principles of AVO.

Automatic exchange of workpieces in CNC horizontal milling centers
Mašek, Dominik ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The thesis focuses on the issue of automatic workpiece change in CNC horizontal milling centres. On the basis of a system analysis of the problem and the current state of the market, a suitable method of automatic workpiece change for a large machine tool, which can be specified as a machine designed for workpieces weighing more than 10 000 kg, is to be proposed. In the first part of the thesis the problem of automatic workpiece change is discussed, followed by a market analysis. The design of the structural solution consists of the design and evaluation of solution variants, the necessary technical calculations of the selected variant, a 3D model and selected drawings. The machine is rated for a load of 40,000 N from the pallet and workpiece.
