Background

The flexible manufacturing is one of two major cores of intelligent manufacturing, and is certainly the mainstream development direction in the future, and the equipment interaction is always an industrial technical problem as a key point of the flexible manufacturing.

In the conventional machining process, after a workpiece is produced, a worker firstly takes off the last machined workpiece (in the process, clamping components on all tools need to be loosened), and then installs the next workpiece to be machined (in the process, all the clamping components need to be screwed). This often takes a lot of time and there is a great risk that this is done directly inside the machine tool. In practice, however, most workpieces are processed for a long time, and if this time can be used, not only the processing time can be greatly saved, but also the risk of operation can be reduced.

The machine tool table has T-slot/threaded holes, and the pallet is often fixed directly to the machine tool table by screws, nuts or bolts. The table top of the machine tool in the field of machine manufacturing is determined when the machine tool is produced and delivered, the size of the table top is fixed with the installation mode of a tool, the table top cannot be replaced basically, and the fixing mode of a jig/workpiece is limited.
