Abstract
In this paper, we first analyze subject to the manipulator's technical requirements, the manipulator to general design, implement various movements of the agency or implementation method, draw a sketch of the overall structure of the design, to estimate the approximate size and weight of the structure.With Solidworks software on material mechanical hand, the overall design modeling, again according to the given requirements and design data for selecting the disc, and then determine the telescopic cylinder models, computational analysis of the lifting cylinder model for estimating the total mass of the telescopic part and a sucker, the above quality estimation after the choice of a good connection, and the rotating motion of the rotary cylinder, but also related to the bearing selection.The involved constantly in the process of analysis and comparison of the advantages and disadvantages of different ways in which the same movement, so as to choose a relatively good scheme and the. After the completion of the design of each part were analyzed, determine the size choose the last models to complete the assembly drawing and parts drawing.
In this paper, the movement of the machine hand of the punch is studied, and its structure is designed.
The results show that the design of the upper and the lower manipulator is relatively compact, and the dynamic performance is relatively stable compared with the hydraulic drive.
The characteristics of this paper: from the implementation mechanism, the driving system of the upper and lower material manipulator structure design, from the economic, practical, aesthetic and other aspects of the design of the structure, the design parameters are designed.
