Mobile turning machining center with vertical workpiece axis
Pomikálek, Adam ; Knoflíček, Radek (referee) ; Marek, Jiří (advisor)
The subject of this diploma thesis is the conceptual design of a mobile lathe centre with a vertical workpiece axis. First, a search in the field of mobile lathes, stationary lathes and methods of their transport is performed. Then, from the described transport machine options, the most suitable transport variant is selected, thanks to which variants of the mobile machine solution are created. Subsequently, the design of the winning variant is fully adapted to the method of transport using containers. Emphasis is placed on simple construction, maximum use of the transport packaging in the machine frame and easy assembly of the machine customer. For these reasons, the machine frame must consist of two containers. Finally, the assembly and adjustment of the machine tool are solved in combination with the verification of the functionality of the proposed concept.
Construction of conveyor superstructure of mobile robot MiR
Adámek, Tomáš ; Szabari, Mikuláš (referee) ; Knoflíček, Radek (advisor)
The subject of this diploma thesis is the design of a conveyor superstructure of a collaborative mobile robot MiR. The first part is a theoretical research basis focused on mobile collaborative technologies and information related to Mobile industrial Robots. The following is a practical part built on previous acquired knowledge. The key issue of the solution is the logistics transport of the PCB magazine in the field of SMT industry. There are created two structural design variants of the superstructure arrangement for the transport of two binders and the most suitable variant is selected on the basis of the multicriteria basic method. The selected alternative of the conveyor top module is then subjected to design calculations. In order to obtain a comprehensive overview of the prototype production, the following section contains drawing documentation, including relevant comments, an economic cost estimate and a risk analysis.
Adaptive order creation in an engineering company
Kučerová, Veronika ; Knoflíček, Radek (referee) ; Marek, Jiří (advisor)
The diploma thesis deals with the influences on business planning, to which companies adapt in effort to succeed in a dynamic production and market environment. The influencing effect causing changes in the production company and the ability to react flexibly can eliminate possible losses or outages in production. However, adaptation leads to significant interventions throughout the company's value chain. The theoretical part presents the possibilities of business planning, which can have a significantly useful impact on management of the order across the pre-production and production stages. In the practical part, simulation models are demonstrated proofing nagative influencing effects. Then the methodology is compiled, witch leads the future user, how to limit or eliminate both internal and external disturbing effects.
New Concept of Car Headlights Test Fixtures
Melničuk, Petr ; Blecha, Radim (referee) ; Knoflíček, Radek (advisor)
The subject of this diploma thesis is designing a way of substituting pneumatic drives with electrical actuators for mechanical movements in a headlights tester. The thesis also contains a theoretical introduction to the issue in the first part. Substitution variants are assessed considering chosen parameters and evaluated using multi-criteria evaluation method. Two final designs are compiled based on the evaluation results and processed into the 3D model of the tester. Drawings are produced for these solutions. In conclusion, a recommendation derived from achieved results is given to the tester manufacturer, ELCOM a.s.
Design and implementation of a test application for measuring dimensions with an optical sensor and a robotic arm
Zagorská, Kateřina ; Vetiška, Jan (referee) ; Knoflíček, Radek (advisor)
This diploma thesis deals with creation of a measuring application using optical sensor and robotic arm in the RobotStudio software. The literature review of the thesis describes the field of optical measuring and calibration. Furthermore, the thesis includes the process of creating a measuring application and outlining issue of calibration of individual parts. The work is supplemented by a demonstration of repeatability measurements and a description of possible errors that may occur if the robot is set incorrectly.
Design of a signle-purpose machine for a control and measuring station for cabling
Bouchal, Tomáš ; Marek, Jiří (referee) ; Knoflíček, Radek (advisor)
The task of this thesis is a design and a construction of a semi-automatic single-purpose machine. This machine is designed for testing seven types of wiring harnesses, which are going to be tested, whether they contain all needed parts. The machine also measures some parts of the harnesses. It is necessary to use more types of sensors in the design and the construction of the single-purpose machine. All controlling and measuring processes are automatic. An operator of the machine just inserts the wiring harness into a fixture, activates the program, then removes controled harness and puts it into the right box. The task of this thesis is solved in a cooperation with Mechatronic Design & Solutions s.r.o. company.
Automatic application system of protecting corners of palletized materials
Havelka, Michal ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
The diploma thesis is about the design of an automatic application system of edge protection corners to palletized material. As the first the diploma thesis briefly discusses actual principles and solutions in area of palletization. After that, there are 4 potential solutions described and measured by multicriteria evaluation method where the most suitable solution is being chosen. Then the actual act of designing of the chosen solution is described and also there are solved necessary calculations. In the end there is risk analysis of new workplace and the drawing documentation of selected nodes is attached. The diploma thesis’ assignment has been made in cooperation with company PHATEC s.r.o. in Litomyšl.
Calculation of the position of the support relative to the spindle on the machine for drilling braking holes
Hanák, Jan ; Knoflíček, Radek (referee) ; Tůma, Zdeněk (advisor)
This bachelor thesis do a research on trains wheels, axles, trains wheelsets and an injection hole which serves for nondestructive disassembly of wheels from axle. The output of this work is an evaluation of possible ways of injection hole drilling and a calculation proposal of drilling spindle tilt versus in relation to support in the course of drilling.
Robotization of machine tools
Tabarka, Roman ; Kočiš, Petr (referee) ; Knoflíček, Radek (advisor)
This bachelor thesis focuses on the robotization of machine tools. This work describes the evaluation of the current state in terms of robotization of CNC machine tools. In addition to the assignment, a case study from practice was prepared.
Support systems (frames, stands) in modern machine tool design
Horák, Jiří ; Marek, Tomáš (referee) ; Knoflíček, Radek (advisor)
This bachelor’s thesis has a character of recherche, and it is focused on a description of an actual state and construction of supporting systems and frames of machine tools. This thesis deals with the construction of machine centers. It also analysis adverse effects arising from the machining, that the machine frame must withstand to maintain sufficient precision. In the thesis, there are also some basic principles for the construction of support systems. The thesis also includes a recherche describing the most common design arrangements in the creation of machine tools, as well as the author’s observations on the possible development of the problem.
