Material clamping and rotating device and lamp inspection machine

The utility model discloses a material clamping and rotating device which comprises an installation shell, a rotating mechanism, a reciprocating operation mechanism and a clamping jaw, the rotating mechanism is provided with an internal rotating mechanism and an external rotating mechanism, and after installation, the external rotating mechanism and the installation shell have an overlapping interval; therefore, the length of the material clamping and rotating device is shortened, the mass of the rotating body is reduced, the rotational inertia of the rotating body is reduced, and the sudden stop requirement in the material transportation and detection process is met. Due to the fact that the device is compact in structure and small in installation height size, installation space is saved, and clamping performance is good. 本实用新型公开了一种物料夹持旋转装置，包括安装壳体、转动机构、往复运行机构和夹爪，转动机构设置为内部转动机构和外部转动机构，安装后，所述外部转动机构与所述安装壳体具有重叠区间；从而缩短该物料夹持旋转装置的长度，减轻旋转体质量，减小旋转体的转动惯量，满足物料运输及检测过程中的急停需求。该装置由于结构紧凑，安装高度尺寸较小，节省安装空间，并且夹持性能好。
