Technical Field
The invention belongs to the field of machining and manufacturing, and particularly relates to a method for accurately clamping and quickly positioning water cutting.
Background
The water cutting is characterized in that water is used as a medium for pressurization, the small hole injection principle is utilized, ultrahigh-pressure water energy is converted into 'water arrows' with the speed of 800-1000 m/s, the water arrows can be used for cutting various soft-based materials and cleaning the surfaces of the objects, and proper abrasive materials (natural pomegranate sand) are added into the water arrows, so that any hard-based object can be cut. The water jet machining technology can effectively solve the problems of large machining difficulty and low efficiency of typical part structures of materials difficult to machine, and realizes efficient and low-cost machining of the parts.
The "cutter" of the water cutting equipment, namely the nozzle, is very convenient for cutting on the integral plate, but when the structural characteristics of the piece to be cut are provided, the cutting needs to refer to the existing characteristics, and the cutting is not easy to be implemented due to the limitation of the cutting equipment, such as the cutting of cast and formed parts and the like.
As shown in fig. 1, a disc-shaped grinding wheel as a grinding tool needs to cut an outer circle into a hexagonal shape or other shapes with a mounting hole as a center, and a water cutting machine tool does not have a grating ruler or other structures, and cannot perform centering operation, so that cutting processing cannot be performed.
