The machine frame is connected with the driving component and mechanism is called the non frame driver mechanism. The Grashof theorem, for hinge four bar mechanism, the only linkage is non frame connecting rod when the rod prime mover, hinge four bar mechanism for double rocker mechanism. The crank block mechanism (swinging hydraulic cylinder), non frame driver is piston. With the election of the original frame connecting rod instead of non frame driving component of the original transform called non frame transform.
In guarantee agencies meet has determined the movement conditions premise. Change known and solve the motion parameters of the position, the motion of the mechanism of input and output sequence changes a transformation method, called inverted motion transformation is the original dynamic transformation of a special case.
According to the car, milling, planing, drilling...... Requirements of different machining processes. Use the motion inversion transformation principle ", cutting movement of metal cutting in the workpiece and the cutting tool, inverted motion transform", can be achieved by adopting different forms of movement, design a variety of different structure of the program, the unique characteristics of processing equipment. For example, application of cutting tool and workpiece motion inversion formed lathe and FT bed, vertical drilling machine with radial drilling machine, planers and shapers and properties of different metal cutting machine tool.
