Technical Field
The invention relates to the technical field of clamping devices, in particular to a clamping device for a mechanical fastener.
Background
The fastener is a mechanical part which is used for fastening connection and has extremely wide application. The fastener is widely used in the industries including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, hydraulic pressure and the like, and various fasteners can be seen on various machines, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical industry, instruments, supplies and the like, and are the most widely applied mechanical basic parts. It features various varieties and specifications, different functions and usages, and very high standardization, serialization and universalization degrees. Thus, one type of fastener that has a national standard is also referred to as a standard fastener, or simply a standard.
In many industrial manufacturing processes, mechanical fasteners such as rivets, screws, bolts, and the like are used to connect or secure two or more items together. Installation of such mechanical fasteners is often performed automatically by machines or robots that are capable of installing the mechanical fasteners faster and with greater precision than humans. For such automated systems, there is a need to quickly and reliably feed mechanical fasteners to the actual mounting mechanism. This can be done manually, and in most cases it is preferred to use a suitable automatic feed mechanism. Thus, automated installation processes for mechanical fasteners often require that the fastener to be installed be picked from a first location (e.g., from a feeding mechanism or from a supply magazine or the like) and moved to another location for further processing or installation. Thus, such a clamping device should not only be reliable and accurate, but it is often desirable to provide mechanical fasteners in a certain orientation.
