Safety of workpiece clamping device
Mahel, Petr ; Bradáč, František (referee) ; Blecha, Petr (advisor)
Master’s thesis is dealing with safety of workpiece clamping device. In the first part we are describing possibilities of clamping workpiece on different machines, legislative conditions in EU and CR in engineering devices, and general demands that refer to harmonized standards for different types of clamping devices. The main target of the thesis are the lists of requirements for hydraulic three-jaw chucks and proposal of two chosen safety applications. The first safety application refers to safety of clamping workpiece in hydraulic chuck. The second safety application is aimed at clamping of workpiece with the help of strap clamps. There is a description of the procedure of calculation of safe tightening moment during assembly of the nut.
