The agency can track the realization of a wide range, such as the sine curve, with the cycloid, with stopping points, curves, images of goldfish heads and so on. Studied the subject before the straight cam combination mechanism is to achieve a heart-line trajectory. First of all, this issue through theoretical analysis, a straight, before the design of cam combination formula, the components come to the location, size and shape of the size of the actual cam profile and theoretical profile and so on. And then on the basis of each component of the institution to carry out the physical design, such as shafts, rails, frame design, etc., and components designed for the assembly combination of entities. Finally, in order to verify the correctness of the design, the issue is still under Proe motion simulation entities. Key words: Cam De
