摘　　要：为了对六面顶压机顶锤的裂纹缺陷进行检测,设计了一种狭小空间图像采集装置对六个顶锤锤面进行图像采集,给出了图像采集装置的整体结构。按照最短路径标准对装置采集图像路径进行优化,建立了距离矩阵模型,并利用遗传算法进行求解寻找最优路径,实现了六组顶锤锤面图像的快速采集。采用D-H法建立了装置的连杆参数模型,通过运动学分析,求出了装置的正运动学方程和逆运动学方程的解。最后利用MATLAB对装置进行仿真分析,验证了所设计装置的合理性。In order to detect crack defects of the top hammer of cubic hinge press,a narrow space image acquisition device was designed to collect images on cubic hinge press,and the structure of the image acquisition device was given.According to the shortest path standard,the image acquisition path cf the device is optimized,the distance matrix model is established,and the genetic algorithm is used to find the optimal path,which realizes the rapid acquisition of six sets of top hammer surface images by using D-H method,the connecting rod parameter model of the device is established.Through kinematics analysis,the forward kinematics equation and the irwerse kinematics equation of the device are solved.Finally,MATLAB is used to simulate the device and verify the rationality of the designed device.
