Abstract

Manipulators with cams as the core components play an important role in industry. According to the designed end trajectory of the cam manipulator and the given necessary structural parameters, the cam profile can be inversely obtained. It is noteworthy that the cam profile is designed based on the theoretical correct size of all structural parameters. The size of the structural parameters of the parts changes within the given tolerance range during machining, so the manufacturing error of the actual structural parameters will inevitably lead to errors between the actual end track and the ideal track. In order to study the influence of structural parameter error on the end track accuracy, the cam profile curve is designed by analytical method, and the specific structural parameters that affect the end track accuracy are obtained through theoretical derivation. The theoretical analysis and provided a basis for strictly controlling the sensitive error in actual processing.
