设计了一种具有多种抓取模式的广义夹持器,使其能够抓取各种薄板零件。该夹持器集成了两组由紧凑型力传递机构驱动的手指;采用D-H法建立了夹持器空间多连杆机构的运动学模型;以最大化工作空间、机械增益和结构刚度为目标进行多目标优化,得到3组夹持器结构参数,并通过Adams软件构建虚拟样机,将优化过程的结果与虚拟样机的结果进行比较,验证了所提出的优化方法可以获得更大的工作空间和更大的机械增益;最后,根据优化后的参数,试制夹持器模型,并通过3种不同的抓取方式实验验证了该结构进行板材抓取的可行性。
In this study
a generalized gripper with multiple modes is designed so that it can grasp various sheet parts. The gripper lies in two sets of fingers and two sets of compact force transmission mechanisms. Firstly
a kinematic model of the hybrid spatial multi-linkage mechanism of gripper is established by means of the D-H method. Multi-objective optimization is performed to maximize workspace
mechanical gain
and structural stiffness; three groups of gripper structure parameters are obtained to construct the virtual prototype; by comparing the results of the optimization process with those of the virtual prototype
the results indicate that the proposed optimization procedure can acquire a larger workspace and greater mechanical gain. Finally
according to the optimized parameters
a generalized gripper is manufactured. Three different grasping mode experiments are carried out to verify the feasibility of the gripper.
