Abstract


Opening and closing mechanism as printing presses key dental institutions, their mechanical performance has a direct impact on the printed overlay accuracy and printing speed. High Point closed teeth biting paper is a novel way , domestic printing high point closed teeth institutions exist in the work process impact of large , noisy and other practical problems , for this situation, this paper intends to adopt conjugate cam -driven approach to solve this problem. On institutions kinematics analysis, dynamic analysis, performance improvement for the organization and methods of theoretical exploration attempts , both Visual C 6.0 software as the platform, the agency conducted a parametric optimization design for enterprises to improve the design presses conjugate cam high closed teeth institutions tool support. This thesis are as follows: ( a ) for a particular model, the first high point conjugate cam teeth institutions were closed kinematic analysis . Reverse motion movement under analysis revealed the relative movement between institutions , synthetic motion analysis to obtain the absolute motion characteristics of the institution . The results show : Acceleration mutations are organizations an impact is an important reason . ( 2 ) to consider the deformation mechanism at high speed components , establish its elastic dynamics model, solving the dynamic response of a body , an impact on the organization , because the noise is given a new interpretation . Found : Yeah institutions influence the elastic deformation of the open bite gripper amount ( open bite maximum deviation reaches 0.1740mm), the dynamic performance of the organization has a certain impact , affecting institutions transfer paper performance. ( 3 ) According to the previous proposed kinematic and dynamic characteristics analysis method, from the cam profile and institutional parameters of two aspects of the organization are optimized analysis . The results showed that: a good selection of cam profile can effectively improve the mechanism motion smooth , rational institutional parameters significantly improved dynamic performance . ( 4 ) in Visual C 6.0 software as a platform for high conjugate cam closed teeth authority will integrate the above optimization method , developed conjugate cam high closed teeth of the parametric design software. The software parameters according to press different agencies , design different conjugate cam mechanism highs closed teeth , and can conduct performance analysis for institutional improvement and optimization platform support.
